Definitions
- the present invention is for mounting systems incorporating a positionable support arm, and more particularly pertains to mounting systems used for supporting a flat panel display in position for viewing or a keyboard in position for operating.
- Prior art mounting systems with positionable support arms have incorporated ball gimbals, simple knob operated pivot mounts, angular slots, and control arms or spring devices which were adjusted to maintain position of a flat panel display supported thereby while offering pivotable capabilities about a small number of pivot centers Often the lack of a sufficient amount of pivots limited the positionable capabilities of the support arm and the flat panel display about a sufficient number of pivotal axes. Lack of friction control and dynamic lift capability made adjustment of the flat panel display difficult and required the use of two hands to accomplish an adjustment. Additionally, movement of the support arm and flat panel display payload in a downward accomplished easily, as the weight of the flat panel display acted in conjunction with gravitational forces and readily overcame the frictional qualities of the friction pivot style joint.
- the general purpose of the present invention is a multi-jointed and pivoted mounting system for support and positioning of a flat panel display or a keyboard.
- a multi-jointed and pivoted mounting system for positioning of a flat panel display including: a pivotal support bracket, a support arm, an arm azimuthal pivot, an arm elevational pivot, an adjustable load counterbalance system, a display roll pivot, a display tilt pivot, a display rotation pivot, and an interface coupling, all acting in concert to support and provide positioning for a flat panel display or any other desired object, such as a keyboard.
- a frictional pivot mount forms the basis of each pivot and is an unique tilt resistive or tilt restraining device that relies on the unique properties of a family of polymer materials having static and dynamic coefficients of friction which are substantially identical, such as Delrin or other ultra high molecular weight polyethylene (UHMWPE) materials.
- UHMWPE ultra high molecular weight polyethylene
- the unique frictional pivot tilt restraining device resistably restrains the flat panel display in the new position as selected. Sufficient friction to maintain position of the flat panel display during use is provided, and yet easy “breakaway” release to reposition the flat panel display to a new operating position or to the storage position is afforded.
- the unique characteristics of the polymer material allow smooth tilt adjustment of the frictional pivot tilt mechanism, and yet provide a constant frictional memory for the preset position of the flat panel display. A predetermined poise is required of the operator to reposition the flat panel display, at which time it remains in the new position.
- One significant aspect and feature of the present invention is a multi-jointed and pivoted mounting system for a flat panel display.
- Another significant aspect and feature of the present invention is a multi-jointed and pivoted mounting system for a flat panel display which is positionable at any point within the given range of travel of a support arm.
- Yet another significant aspect and feature of the present invention is a plurality of pivots incorporating ultra high molecular weight polyethylene (UHMWPE) disks or washers (the subject of a pending patent application).
- UHMWPE ultra high molecular weight polyethylene
- Still another significant aspect and feature of the present invention is a plurality of pivots including an arm azimuthal pivot, an arm elevational pivot, a display roll pivot, a display tilt pivot and a display rotation pivot.
- a further significant aspect and feature of the present invention is an interface connecting the display rotation pivot to the display tilt pivot.
- a still further significant aspect and feature of the present invention is a load counterbalance mechanism adjuster whose location and angle of adjustment in respect to the arm elevational pivot is derived through the use of a computerized mathematical algorithm for each mounting option offered in the system, to provide a user adjustable counterbalance pivot point for a broad range of display or payload weights.
- a still further significant aspect and feature of the present invention is a load counterbalance mechanism which provides a dynamically increasing counterbalance moment which corresponds to the increasing moment load on the support arm as the support arm traverses from 0° vertical to 90° horizontal and which provides a dynamically decreasing counterbalance moment which corresponds to the decreasing moment load on the support arm as the support arm moves downward from 90° horizontal to 180° vertical to provide a linear counterbalance force throughout the total adjustable range of the support arm.
- a still further significant aspect and feature of the present invention is a nitrogen gas spring counterbalance mechanism which operates physically within the pivot point of the support arm, allowing 180° ( ⁇ 90°) rotation of the flat panel display or other load.
- a still further significant aspect and feature of the present invention is an arm elevation frictional pivot, independent of the arm counterbalance system, which provides for establishment of a predetermined, bi-directional frictional moving force which allows single-handed movement of the flat panel display within OSHA guidelines and yet provides a stable viewing or operating platform for touch screen or keyboard applications.
- FIG. 1 Another significant aspect and feature of the present invention is a pivot/ratchet assembly which attaches a keyboard tray to the outer end of a support arm.
- the pivot/ratchet assembly offers incremental pivotal positioning in an upward direction about arrays of ratchet teeth and includes a release lever assembly which is utilized to bypass the ratcheting feature to allow manual repositioning for downward positioning of the keyboard tray.
- the pivot/ratchet assembly can also be incorporated to support a flat panel display.

- Smooth and quieted transition of a roll pin, such as roll pin 1354 between tooth ends is promoted by the use of an arced surface, such as arc surface 1398 , instead of abrupt angled surfaces such as are found in other ratcheting devices.
- less deflection of the roll pin 1354 and shorter actuation of the release lever assembly 1346 is required to transit between rounded teeth as opposed to using non-rounded teeth whose surfaces form a sharp angle.
Abstract
Multi-jointed and pivoted mounting systems for support of a flat panel video display and/or keyboard tray, incorporating a plurality of pivot points providing for pivotal motion of one or more components about a plurality of vertical and horizontal axes. Support arms having elevational pivot assemblies, including plastic friction washers and gas springs, offer elevational arm control requiring constant and predetermined positioning effort on the part of the video display operator and keyboard operator.
Description
- This patent application is a continuation-in-part (CIP) of U.S. Ser. No. 08/660,397 filed Jun. 7, 1996, entitled “Mounting System for Flat Panel Display, Keyboard, and Stand” by the same inventors.
- 1. Field of the Invention
- The present invention is for mounting systems incorporating a positionable support arm, and more particularly pertains to mounting systems used for supporting a flat panel display in position for viewing or a keyboard in position for operating.
- 2. Description of the Prior Art
- Prior art mounting systems with positionable support arms have incorporated ball gimbals, simple knob operated pivot mounts, angular slots, and control arms or spring devices which were adjusted to maintain position of a flat panel display supported thereby while offering pivotable capabilities about a small number of pivot centers Often the lack of a sufficient amount of pivots limited the positionable capabilities of the support arm and the flat panel display about a sufficient number of pivotal axes. Lack of friction control and dynamic lift capability made adjustment of the flat panel display difficult and required the use of two hands to accomplish an adjustment. Additionally, movement of the support arm and flat panel display payload in a downward accomplished easily, as the weight of the flat panel display acted in conjunction with gravitational forces and readily overcame the frictional qualities of the friction pivot style joint. However, movement in an upward direction was not so easily and readily accomplished, as the upward force required to raise the flat panel display had to overcome the friction of the friction style joint as well as the force of gravity. In addition, two-handed adjustments added to the complexity of adjusting the flat panel display. Clearly what is needed is a positional flat panel display mounting system which is positionable over a multitude of axes, which can be repositioned without secondary controls, which incorporates an adjustable counterbalance or lifting system to provide “co-equal” movement force in either the upward or downward direction, which incorporates frictional systems which can be used to establish pre-determined moving forces within OSHA guidelines, and which provides stability for touch screen applications.
- The general purpose of the present invention is a multi-jointed and pivoted mounting system for support and positioning of a flat panel display or a keyboard.
- According to one embodiment of the present invention, there is provided a multi-jointed and pivoted mounting system for positioning of a flat panel display including: a pivotal support bracket, a support arm, an arm azimuthal pivot, an arm elevational pivot, an adjustable load counterbalance system, a display roll pivot, a display tilt pivot, a display rotation pivot, and an interface coupling, all acting in concert to support and provide positioning for a flat panel display or any other desired object, such as a keyboard.
- A frictional pivot mount forms the basis of each pivot and is an unique tilt resistive or tilt restraining device that relies on the unique properties of a family of polymer materials having static and dynamic coefficients of friction which are substantially identical, such as Delrin or other ultra high molecular weight polyethylene (UHMWPE) materials. The result provided by the static and dynamic coefficients of friction of UHMWPE materials, such as utilized in disks or washers of the unique frictional pivot tilt restraining device, is that a flat panel display remains in any tilt position selected by the user. If the user wishes to tiltingly reposition the flat panel display upwardly or downwardly, or any other position, the flat panel display must be manually repositioned to overcome the frictional pivot tilt restraining device. Once the flat panel display is tilted to a different selected position, the unique frictional pivot tilt restraining device resistably restrains the flat panel display in the new position as selected. Sufficient friction to maintain position of the flat panel display during use is provided, and yet easy “breakaway” release to reposition the flat panel display to a new operating position or to the storage position is afforded. The unique characteristics of the polymer material allow smooth tilt adjustment of the frictional pivot tilt mechanism, and yet provide a constant frictional memory for the preset position of the flat panel display. A predetermined poise is required of the operator to reposition the flat panel display, at which time it remains in the new position.
- One significant aspect and feature of the present invention is a multi-jointed and pivoted mounting system for a flat panel display.
- Another significant aspect and feature of the present invention is a multi-jointed and pivoted mounting system for a flat panel display which is positionable at any point within the given range of travel of a support arm.
- Yet another significant aspect and feature of the present invention is a plurality of pivots incorporating ultra high molecular weight polyethylene (UHMWPE) disks or washers (the subject of a pending patent application).
- Still another significant aspect and feature of the present invention is a plurality of pivots including an arm azimuthal pivot, an arm elevational pivot, a display roll pivot, a display tilt pivot and a display rotation pivot.
- A further significant aspect and feature of the present invention is an interface connecting the display rotation pivot to the display tilt pivot.
- A still further significant aspect and feature of the present invention is a load counterbalance mechanism adjuster whose location and angle of adjustment in respect to the arm elevational pivot is derived through the use of a computerized mathematical algorithm for each mounting option offered in the system, to provide a user adjustable counterbalance pivot point for a broad range of display or payload weights.
- A still further significant aspect and feature of the present invention is a load counterbalance mechanism which provides a dynamically increasing counterbalance moment which corresponds to the increasing moment load on the support arm as the support arm traverses from 0° vertical to 90° horizontal and which provides a dynamically decreasing counterbalance moment which corresponds to the decreasing moment load on the support arm as the support arm moves downward from 90° horizontal to 180° vertical to provide a linear counterbalance force throughout the total adjustable range of the support arm.
- A still further significant aspect and feature of the present invention is a nitrogen gas spring counterbalance mechanism which operates physically within the pivot point of the support arm, allowing 180° (±90°) rotation of the flat panel display or other load.
- A still further significant aspect and feature of the present invention is an arm elevation frictional pivot, independent of the arm counterbalance system, which provides for establishment of a predetermined, bi-directional frictional moving force which allows single-handed movement of the flat panel display within OSHA guidelines and yet provides a stable viewing or operating platform for touch screen or keyboard applications.
- Another significant aspect and feature of the present invention is a pivot/ratchet assembly which attaches a keyboard tray to the outer end of a support arm. The pivot/ratchet assembly offers incremental pivotal positioning in an upward direction about arrays of ratchet teeth and includes a release lever assembly which is utilized to bypass the ratcheting feature to allow manual repositioning for downward positioning of the keyboard tray. The pivot/ratchet assembly can also be incorporated to support a flat panel display.
- Having thus described significant aspects and features of the present invention, it is the principal object of the present invention to provide a multi-jointed and pivotable mounting system for a flat panel video display or a keyboard.
- Other objects of the present invention and many of the attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, in which like reference numerals designate like parts throughout the figures thereof and wherein:

vertical surface mount 10 supporting aflat panel display 16.Angled bracket assemblies mount track plates arm elevation bracket 22 and its associated components.Pivotal support bracket 22 serves as a pivotal mount forsupport arm 24 and other associated components including a gas (e.g., nitrogen)spring 25 and left and rightsupport arm members Gas spring 25 secures between thepivotal support bracket 22 and thesupport arm 24, as later described in detail. Thepivotal support bracket 22 pivots aboutvertical axis 26 to carry thesupport arm 24, a three-axis pivot 30, and theflat panel display 16 as a unit about thevertical axis 26.Support arm 24 pivotally secures to thepivotal support bracket 22 to offer movement of thesupport arm 24, the three-axis pivot 30, and theflat panel display 16 as a unit about thehorizontal axis 28. The three-axis pivot 30, as described later in detail, secures at theoutboard end 24 b of thesupport arm 24 to support theflat panel display 16. - FIG. 2 illustrates a side view of the elements of FIG. 1. Illustrated in particular is the three-
axis pivot 30 includingpivot assemblies outboard end 24 b ofsupport arm 24 and a component mount orbracket 38 on the rear surface of theflat panel display 16. Theinboard end 24 a of the support arm is pivotally secured to thepivotal support bracket 22 to provide elevational pivotal positioning of thesupport arm 24 and its payload about thehorizontal axis 28 illustrated in FIG. 1. The three-axis pivot 30 and theflat panel display 16 can be elevationally positioned about thehorizontal axis 28 in conjunction with and by the action of thesupport arm 24. As viewed in FIG. 2,pivot assembly 32 offers rotation of the members outboard of thepivot assembly 32, that is to say,pivot assemblies flat panel display 16, about thevertical axis 40 extending through thepivot assembly 32.Pivot assembly 34 offers tilt of the members outboard of thepivot assembly 34, that is to say,pivot assembly 36 andflat panel display 16, about a horizontally alignedaxis 42 extending through thepivot assembly 34, as illustrated in FIG. 4.Pivot assembly 36 offers tilt of the members outboard of thepivot assembly 36, that is to say,flat panel display 16, about aroll axis 44 extending through thepivot assembly 36. - The
pivot assembly 32, of the three-axis pivot 30, secures to vertically orientedflanges support arm 24. - Now, with reference to FIGS. 2 and 4 the three-
axis pivot 30 is described.Pivot assembly 32 includesangle brackets arm flanges end 24 b of thesupport arm 24, UHMWPE (ultra high molecular weight polyethylene)disks angle brackets bolt 58 having twoBelleville washers 59 and 60 andnut 62. Aligned to the interior surfaces of theUHMWPE disks angle brackets assembly 34.Bolt 58 extends through thebrackets UHMWPE disks Belleville washers 59 and 60 andnut 62.Bolt 58 is tensioned across the assembly to provide suitable friction to stabilizepivot assemblies flat panel display 16.Pivot assembly 34, constructed in the same manner and fashion aspivot assembly 32, includesangle brackets angle brackets pivot assembly 32,UHMWPE disks angle brackets bolt 76 having twoBelleville washers nut 80. Aligned to the interior surfaces of theUHMWPE disks angle brackets assembly 36.Bolt 76 extends through thebrackets UHMWPE disks Belleville washers nut 80.Bolt 76 is tensioned across the assembly to provide suitable friction to stabilizepivot assembly 36 andflat panel display 16, preventing thepivot assembly 36 from falling due to its weight. The frictional tension is adjustable to accommodate various weights of flat panel displays.Pivot assembly 36 includes aplate 86 suitably secured to the flanges of theangle brackets UHMWPE disk 88, aplanar portion 38 a ofbracket 38, abolt 90, aBelleville washer 92 and anut 94.Bolt 90 extends through theplate 86,UHMWPE washer 88,planar portion 38 a,Belleville washer 92 andnut 94, and is adjusted to provide tension across the assembly to provide suitable friction. - It can be appreciated that an almost infinitesimal number of positionings of the
flat panel display 16 are available incorporating the three-axis swiveling of theflat panel display 16 at the three-axis pivot 30 and the horizontal and elevational positionability provided by thepivotal support bracket 22. In each case it can be appreciated that theflat panel display 16 must be adjustable and yet stay in the position selected by the user. If the user wishes to tiltingly reposition theflat panel display 16 upwardly, downwardly, left to right or in a circular plane, theflat panel display 16 must be manually repositioned to overcome the friction imposed bypivot assemblies flat panel display 16 is moved to a different selected position, the unique tilt restraining devices inherent inpivot assemblies flat panel display 16 in the new position as selected. Sufficient friction to maintain position of theflat panel display 16 during use is provided but easy “breakaway” release to reposition theflat panel display 16 to a new operating position or to a storage position is afforded. The unique characteristics of the polymermaterial UHMWPE disks Belleville washers flat panel display 16 and yet provide a constant frictional memory for the present position of theflat panel display 16. A predetermined poise is required of the operator to reposition theflat panel display 16, at which time it remains in the new position. Each pivot point is also adjustable to accommodate various flat panel displays and different length arms. - FIG. 3 illustrates a rotated isometric view of the
pivotal support bracket 22, FIG. 5 illustrates a front view of thepivotal support bracket 22 secured to thetrack plates pivotal support bracket 22 secured to thetrack plates pivotal support bracket 22 is now described. Thepivotal support bracket 22 includes acentral bracket 96 pivotally suspended betweenangled support brackets angled bracket assemblies Angled support brackets planar portions track plates Planar portions Planar portions planar portions central bracket 96, as later described in detail. - The
central bracket 96 includes a centralplanar area 102 havingplanar members planar members semi-circular members UHMWPE disks planar members Support arm 24, illustrated in FIG. 1, includes a leftsupport arm member 112 and a rightsupport arm member 114. Referring to FIG. 3, leftsupport arm member 112 includes a disk-like portion 112 a corresponding to the size of theUHMWPE disk 108. Aplanar member 112 b having aflange 112 c extends from the disk-like portion 112 a to form part of thesupport arm 24. Rightsupport arm member 114 is not shown in FIG. 3 for purposes of brevity and clarity. However, as can be seen from FIGS. 4 and 6, rightsupport arm member 114 is similar to leftsupport arm member 112 and includes a disk-like portion 114 a corresponding to the size ofUHMWPE disk 110 and aplanar member 114 b having aflange 114 c and extending from the disk-like portion 114 a to form the other part of thesupport arm 24.Flanges pivot tabs support arm 24 at a ±90° rotation. FIG. 5 illustrates disk-like portions support arm members support arm members like portion 112 a (partially in cross section) and a cutaway view of the disk-like portion 114 a for purposes of brevity and clarity. Acaptive stud 116 secures in the disk-like portion 112 a of the leftsupport arm member 112 and extends through anoilite bearing 118 and accompanyingoilite washer 120 assembly centered about and alongholes UHMWPE disk 108 and theplanar member 104, respectively, through asteel washer 122, aBelleville washer 124 and anut 126.Nut 126 is adjusted to provide tension across the assembly to provide a predetermined suitable friction to stabilize the leftsupport arm member 112, pivot assembly, and the flat panel display 16 (not shown). The weight of theflat panel display 16 is counterbalanced bygas spring 25. In a similar fashion, acaptive stud 128 secures in the disk-like portion 114 a of the rightsupport arm member 114 and extends through an oilite bearing (not shown, but similar to oilite bearing 118) and accompanyingoilite washer 119 assembly centered about and along holes in theUHMWPE disk 110 and theplanar member 106, through asteel washer 132, aBelleville washer 134, and anut 136. Anut 136 is adjusted to provide tension across the assembly to provide a predetermined suitable friction to stabilize the rightsupport arm member 114, pivot assembly, and the flat panel display 16 (not shown). - A predetermined frictional force is thus established to ensure that the vertical motion of
support arm 24 remains in any position selected by the user. If the user wishes to reposition theflat panel display 16 upwardly or downwardly, theflat panel display 16 must be manually repositioned to overcome the support arm rotational friction established above. Once theflat panel display 16 is moved to a different selected position, the unique friction devices will resistably restrain theflat panel display 16 in its new position as selected. Sufficient friction to maintain position of theflat panel display 16 during use is provided but easy “breakaway” release to reposition theflat panel display 16 to a new operating position or to a storage position is afforded. - The unique characteristics of the
polymer UHMWPE disks Belleville washers flat panel display 16 and yet provide a constant frictional memory for the preset position of theflat panel display 16. A predetermined poise is required of the operator to move theflat panel display 16, at which time it remains in the new position. This predetermined vertical positioning force is established and functions independently of thesupport arm 24 payload counterbalance, which is performed by an adjustable gas spring assembly described below. - A positionable and adjustable
gas spring mount 140 is adjustably mounted to adjustably slide along the centralplanar area 102 as positioned by a threadedshaft 142 havingnuts slot 148 at the lower end of the threadedshaft 142 provides for rotational adjustability of the threadedshaft 142 and thus thegas spring mount 140 along the centralplanar area 102. The angle of centralplanar area 102 and thus the angle of threadedadjustment shaft 142 in relation to thesupport arm 24horizontal pivot axis 28, as shown in FIG. 1, is predetermined by a computerized mathematical algorithm for each mounting option or weight to provide a user adjustable optimum counterbalance force pivot position corresponding to the specific weight of theflat panel display 16 mounted onsupport arm 24. See FIGS. 18, 19 and 23 for examples of threadedshafts gas spring mount 140 is positionable in the space between leftsupport arm member 112 and rightsupport arm member 114 up to and intersecting with thesupport arm 24horizontal axis 28, as shown in FIG. 1, allowing thesupport arm 24 to rotate and counterbalance a variable payload in a range of 0° to 180°.Tabs planar area 102 to support the ends of the threadedshaft 142 by means of holes located in thetabs shaft 142 passes. A threadedhole 154 central to thegas spring mount 140 accommodates the threadedshaft 142 for purposes of adjustment of thegas spring mount 140.Gas spring mount 140 also includesopposed tabs pivot bolt 160 passes through theopposed tabs gas spring 25. Theoutboard end 183 of thegas spring 25 secures to apivot pin 184 passing through left and rightsupport arm members plastic spacers - The load counterbalance mechanism provides a dynamically increasing counterbalance moment which corresponds to the increasing moment load on the
support arm 24 as thesupport arm 24 traverses from 0° vertical to 90° horizontal and provides a dynamically decreasing counterbalance moment which corresponds to the decreasing moment load on thesupport arm 24 as thesupport arm 24 moves downward from 90° horizontal to 180° vertical to provide a linear counterbalance force throughout the total adjustable range of thesupport arm 24. - Pivot
tabs planar members angled bracket assemblies bolt 166 passes through aBelleville washer 168, throughplanar portion 100 b ofangled support bracket 100, through aUHMWPE washer 170, and throughpivot tab 162, and secures into a threadedinsert 172 secured to the inner wall of thepivot tab 162.Bolt 166 is adjusted to provide desirable frictional properties across the assembly. In a similar fashion, and atangled bracket assembly 18, abolt 174 passes through aBelleville washer 176, throughplanar portion 98 b ofangled support bracket 98, through aUHMWPE washer 178, and throughpivot tab 164, and secures into a threaded insert 180 (directly belownut 146 in FIG. 4) secured to the inner wall of thepivot tab 164.Bolt 174 is adjusted to provide desirable frictional properties across the assembly. This friction stabilizes the entire assembly as it pivots aboutvertical axis 26 shown in FIG. 1. Asemi-circular slot 182 passes through theplanar portion 100 b ofangled support bracket 100,UHMWPE washer 170, andpivot tab 162 for adjustability access to theslot 148 in the end of the threadedshaft 142.UHMWPE washer 170 is positioned and secured with respect to theangled support bracket 100 by means of mutually engaged interlock tabs (not illustrated) to prevent washer rotation and secure alignment of thesemi-circular slot 182 common to theUHMWPE washer 170,pivot tab 162, andplanar portion 100 b ofangled support bracket 100. - FIG. 4 illustrates a front view of the
support arm 24 in the fully lowered position with attached three-axis pivot 30 andflat panel display 16. Illustrated in particular is a view of the three-axis pivot 30 and of thegas spring 25 secured between thegas spring mount 140 and thepivot pin 184, withplastic spacers support arm 24. - FIG. 5 illustrates a front view of the
pivotal support bracket 22 secured to thetrack plates - FIG. 6 illustrates a bottom view in partial cross section of the
pivotal support bracket 22 secured to thetrack plates - FIGS.7-10 are side views in partial cutaway of the
vertical surface mount 10 showing various positionings of thesupport arm 24 along its 180°pivot range 191 abouthorizontal axis 28 shown in FIG. 1. The three-axis pivot 30 and theflat panel display 16 are not illustrated for purposes of brevity and clarity. In these particular examples thegas spring mount 140 is adjusted to the maximum load position, thus providing the greatest offset fromhorizontal pivot axis 28, providing the greatest gas spring assistance. As adjustablegas spring mount 140 is adjusted closer to thehorizontal axis 28, the counterbalance pivot point is lessened, which is desirable with smaller, lighter loads. Infinite adjustability within a range of payloads is desirable and attainable with this design. Also illustrated is the ability of thesupport arm 24 to travel from +90° (vertical up position) to −90° (vertical down position). - It should be noted that for each and every various monitor weight there is an optimum position for the
gas spring mount 140. And, even further, it should be noted that at each adjustment point (weight of monitor), thesupport arm 24 will, by design, dynamically adjust the counterbalance moment as thesupport arm 24 is moved through the 180° range of travel. - The load moment increases as the
support arm 24 travels from 0° to 90°, reaching its maximum at 900. It then decreases as thesupport arm 24 is moved from 90° to 180°. The load moment is at its minimum (zero) when thesupport arm 24 is vertical, 0° or 180°. - The counterbalance moment increases and decreases essentially to cancel the load moment as the
support arm 24 travels from 0° to 90° to 180°. The dynamic aspect of the counterbalance is created by the relationship of the three pivot points in the system. Point B is the pivot of thesupport arm 24 through thehorizontal axis 28. Point A is the gasspring pivot bolt 160 on thepivotal support bracket 22. Point C is the gas spring pivot atpivot pin 184 away from thesupport arm 24 pivot at B. At 0° and 180° the three pivot points B, A and C are all in line, thus providing zero counterbalance moment. As thesupport arm 24 pivots about the pivot at B, the angle A-C-B increases to its maximum at 90° and then decreases back to zero at 180°. This dynamic angle exactly corresponds with the load moment. The angle created about these pivot points puts thegas spring 25 in the correct position to counterbalance the load moment for each position of thesupport arm 24. - FIG. 11 illustrates a top view of the elements of FIG. 1 and the
pivot arc 190 of thesupport arm 24 aboutvertical axis 26, as shown in FIG. 1, wherebolt 174 secures angledbracket assembly 18 to thepivotal support bracket 22. Thepivot arc 190 is capable of ±90° range, or greater, depending on the mounting configuration. The limit would normally be set by the width of theflat panel display 16 when it contacts the wall, plate, machine or other such surface, prior to the 90° pivot.Pivot assembly 32 allows theflat panel display 16 to be pivoted aboutvertical axis 40, shown in FIG. 2, allowing theflat panel display 16 to be positioned parallel to the wall, plate, machine or other such surface. - FIG. 12 illustrates a perspective view of another
vertical surface mount 210, the first alternative mounting system embodiment, supporting aflat panel display 216. Pivotal support bracket orarm elevation bracket 222 serves as a pivotal mount forsupport arm 224 and other associated components including a gas (e.g., nitrogen)spring 225.Gas spring 225 secures between thepivotal support bracket 222 and thesupport arm 224, as later described in detail.Support arm 224 pivotally secures to thepivotal support bracket 222 to offer movement of thesupport arm 224, the single-axis pivot 230, as shown in FIG. 13, and theflat panel display 216 as a unit about thehorizontal axis 228. Alternately, the three-axis pivot 30, such as previously described in detail, can be secured at theoutboard end 224 b of thesupport arm 224 to support theflat panel display 216. - FIG. 13 illustrates a side view of the elements of FIG. 12. Illustrated in particular is the single-
axis pivot 230 suitably secured between theoutboard end 224 b ofsupport arm 224 and a component mount orbracket 238 on the rear surface of theflat panel display 216. Theinboard end 224 a of thesupport arm 224 is pivotally secured to thepivotal support bracket 222 to provide elevational pivotal positioning of thesupport arm 224 and itsflat panel display 216 payload about thehorizontal axis 228 illustrated in FIG. 12. The single-axis pivot 230 and theflat panel display 216 can be elevationally positioned about thehorizontal axis 228 in conjunction with and by the action of the pivotedsupport arm 224. As viewed in FIG. 13, the single-axis pivot 230 offers tilt of theflat panel display 216 about thehorizontal axis 240, as shown in FIG. 15, extending through the single-axis pivot 230. - The single-

Thesupport arm 802 with asteel coil spring 810 is mounted toangled base 512 in the same fashion using the same hardware as shown and described in FIG. 23. - FIG. 25 illustrates a perspective view of a
keyboard support system 1000, the fifth alternative mounting system embodiment. Thekeyboard support system 1000 consists of akeyboard tray 1010, amouse pad tray 1012, a pivot/brake assembly 1072 and asupport arm 1014. Thekeyboard tray 1010 includes a fixedportion 1016 with mountinglip 1018 which extends perpendicular to the fixedportion 1016. Cable access holes 1022, 1024 and 1026 are located at the junction of the fixedportion 1016 and the mountinglip 1018. The mountinglip 1018 also has a plurality of mounting holes 1020 a-1020 n for securing thekeyboard tray 1010 to the pivot/brake assembly 1072 and connectedsupport arm 1014.Support arm 1014 is designed and constructed similarly to supportarm 224 of FIG. 15. The pivot/brake assembly 1072 attaches to supportarm 1014 with a plurality of screw and nut combinations 1021 a-1021 n. Thekeyboard tray 1010 also includes aslide plate 1028 having a right extended member 1030, a leftextended member 1032,slots machine screws front lip 1038. The right and leftextended members 1030 and 1032 accommodate various lengths of keyboard wrist rests. Theslide plate 1028 slidingly secures to the fixedportion 1016 viaslots machine screws lip 1018 andfront lip 1038, when properly adjusted, capture and secure the keyboard and keyboard wrist rest to thekeyboard tray 1010. - The
mouse pad tray 1012 consists of acontiguous slide plate 1054 having an upperplanar member 1056 and a lowerplanar member 1058, which are vertically offset and joined by anintermediate portion 1060.Mouse pad tray 1012, having aplanar surface 1044 andlips planar member 1058 of thecontiguous slide plate 1054 via hook and loop material, double-sided tape or like materials. The upperplanar member 1056 slidingly engagesslide channels machine screw 1064, having aknob 1064 a, extends through a threaded hole incontiguous slide plate 1054 and upward intoslot 1062.Machine screw 1066, having aknob 1066 a, extends through a threaded hole in thecontiguous slide plate 1054 to lock or stop all movement of themouse pad tray 1012.Machine screw 1064 is a stop to limit lateral travel of themouse pad tray 1012. Themachine screw 1064 can be loosened by theknob 1064 a to back themachine screw 1064 out ofslot 1062 to allow themouse pad tray 1012 to be removed and reinserted on the other side of the keyboard tray fixedportion 1016. - FIG. 26 illustrates a perspective view of the pivot/
brake assembly 1072.Support arm 1014 is not shown for purposes of brevity and clarity. The pivot/brake assembly 1072 includes aU-shaped bracket 1074 with aleft member 1074 a and aright member 1074 b which supportfriction assembly 1100 andbrake assembly 1102, respectively. - The
friction assembly 1100 is now described.Bolt 1084 extends through angledbracket 1076,UHMWPE disk 1088, theleft member 1074 a ofU-shaped bracket 1074,UHMWPE disk 1090, angledbracket 1078, andBelleville washer 1104, all of which are collectively frictionally secured vianut 1096, as shown in FIG. 27. A predetermined frictional force is thus established to ensure that the tilting motion ofkeyboard tray 1010, shown in FIG. 25, remains in any position selected by the user. If the user wishes to reposition the tilt of thekeyboard tray 1010, thekeyboard tray 1010 must be manually repositioned to overcome thekeyboard tray 1010 tilting friction established above. Once thekeyboard tray 1010 is moved to a different selected position, the unique friction devices will resistably restrain thekeyboard tray 1010 in its new position as selected. Sufficient friction to maintain position of thekeyboard tray 1010 during preparation for use is provided, but easy “breakaway” release to reposition thekeyboard tray 1010 to a new operating position or to a storage position is afforded. Thekeyboard tray 1010 is locked into any position to provide increased stability usingbrake assembly 1102, which will be described in detail later, before thekeyboard tray 1010 is used for mouse or keyboard input. - The unique characteristics of the
UHMWPE disks Belleville washer 1104 allow smooth adjustment of the keyboard tray and yet provide a constant frictional memory for the preset position of the keyboard tray. A predetermined poise is required of the operator to move the keyboard tray, at which time it remains in the new position. - The
brake assembly 1102 is now described.Brake assembly 1102 has abrake handle 1108 having a threadedshaft 1086 which extends from the lower portion of thebrake handle 1108 at a 90° angle, and extends throughwasher 1106, shown in FIG. 27, angledbracket 1082,steel washer 1094, theright member 1074 b ofU-shaped bracket 1074,steel washer 1092, and angledbracket 1080, all of which are collectively frictionally secured vianut 1098, which is welded toangled bracket 1080. Rotatingbrake handle 1108 will cause threadedshaft 1086 to turn in either direction, either lessening the frictional tension, allowing for a new tilt position to be selected, or increasing the frictional tension, which will act as a brake mechanism, locking thekeyboard tray 1010 into position. - FIG. 27 illustrates a top view of the pivot/
brake assembly 1072. - FIG. 28 illustrates a side view of the
keyboard support system 1000. Illustrated in particular are theslide channels contiguous slide plate 1054 of themouse pad tray 1012 slidingly engages thekeyboard tray 1010. The upperplanar member 1056 of themouse pad tray 1012 is captured by theslide channels - Also illustrated in FIG. 28 is a plurality of mounting bolts1112 a-1112 n and nuts 1110 a-1110 n which secure the mounting
lip 1018 of thekeyboard tray 1010 to the pivot/brake assembly 1072. - FIG. 29 illustrates a perspective view of a sixth alternative mounting system embodiment in the form of a rolling
cart assembly 1200. The rollingcart assembly 1200 includes a base 1210 with a plurality of dual wheel casters 1212 a-1212 n which supports amounting pole 1214. Secured to themounting pole 1214, via a plurality of pole mounting brackets 1216 a-1216 n, are thepivotal support bracket 222 and thesupport arm 224 of avertical surface mount 210 which supportsflat panel display 216, and thesupport arm 1014 in connection with pivot/brake assembly 1072 of akeyboard support system 1000. Also supported by themounting pole 1214 is aCPU mounting bracket 1218. Amail tray bracket 1220 is secured to the-base 1210 of themounting pole 1214. The combination of these elements creates a mobile, easily adjustable, computer work station. The adjustability features of the rollingcart assembly 1200 allow the mobile work station to be easily adjusted for standing and sitting work applications, providing the ability to maintain a 16-inch or other desired separation between the monitor and keyboard in any position. Thesupport arm 224 andsupport arm 1014 may be positioned vertically for easy storage, ease of mobility and other considerations. - FIG. 30 illustrates an isometric view of a pivot/
ratchet assembly 1300 which can be incorporated and utilized as an alternative for (a) thepivot assembly 34 for support of theflat panel display 16 of FIG. 2; (b) the single-axis pivot 230 for support of theflat panel display 216 of FIG. 13; (c) the single-axis pivot 430 for support of a flat panel display of FIG. 19; (d) the single-axis pivot 530 for support of theflat panel display 516 of FIG. 21; (e) pivot/brake assembly 1072 for support of thekeyboard tray 1010 of FIG. 25; and (f) the support of any keyboard or keyboard tray, keyboard/mouse/trackball tray, flat panel or other display or any other device requiring pivotal support. - With reference to FIGS. 30, 31 and32 the structure of the pivot/
ratchet assembly 1300 is now described where FIG. 31 illustrates an isometric exploded view and FIG. 32 illustrates an isometric view of a partially assembled pivot/ratchet assembly 1300. AU-shaped bracket 1302 is central to the pivot/ratchet assembly 1300 and includes aplanar portion 1302 a having a plurality of mounting holes 1304 a-1304 n. A leftplanar member 1302 b and a rightplanar member 1302 c extend at right angles from theplanar portion 1302 a. Threadedpivot studs planar member 1302 b and the rightplanar member 1302 c, respectively. A semi-circular array of smoothedratchet teeth 1310, whose radius center is co-located with the center of thepivot stud 1306, is located at one end of the leftplanar member 1302 b. Another semi-circular array of smoothedratchet teeth 1312, whose radius center is co-located with the center of thepivot stud 1308, is located at one end of the rightplanar member 1302 c. In order, and with reference to FIG. 31, aUHMWPE washer 1314, anangle bracket 1316 having alarge pivot hole 1318, aBelleville washer 1320, athrust washer 1322, and aNylock nut 1324 align and secure over and about the threadedpivot stud 1306. In the same fashion, aUHMWPE washer 1326, anangle bracket 1328 having alarge pivot hole 1330, aBelleville washer 1332, athrust washer 1334, and aNylock nut 1336 align and secure over and about the threadedpivot stud 1308.Angle bracket 1316 includes a largeplanar member 1316 a, one end of which is rounded, having anupper pivot hole 1338 and alower hole 1340 in addition to thelarge pivot hole 1318 and also includes a smallplanar member 1316 b extending perpendicular to the largeplanar member 1316 a.Angle bracket 1328 includes a largeplanar member 1328 a, one end of which is rounded, having anupper pivot hole 1342 and alower hole 1344 in addition to thelarge pivot hole 1330 and also includes a smallplanar member 1328 b extending perpendicular to the largeplanar member 1328 a. Mountingholes holes planar members keyboard tray 1010, previously illustrated, or, in the alternative, to a flat panel display. - A
release lever assembly 1346 pivotally secures and aligns between theleft angle bracket 1316 and theright angle bracket 1328 and interfaces with the semi-circular arrays of smoothedratchet teeth release lever assembly 1346 includes a configuredbody member 1348 formed from a planar member and having a plurality of tabs extending at right angles from a lower centralplanar portion 1357 for the mounting of apivot pin 1350 and rollpins body member 1348 includes, coplanar with the centralplanar portion 1357, arelease tab 1356 for manual release from the ratcheting feature which is described later in detail. A vertically aligned outerleft tab 1358 and an opposing vertically alignedouter right tab 1360 extend at right angles from the centralplanar portion 1357. Pivot holes 1362 and 1364 are located in the upper regions of the outerleft tab 1358 and theouter right tab 1360, respectively.Holes left tab 1358 and theouter right tab 1360, respectively.Pivot pin 1350 aligns throughpivot holes left tab 1358 and theouter right tab 1360, respectively, as well as throughrespective holes angle brackets pivot pin 1350 to positionally fix thepivot pin 1350 in position. opposing vertically aligned left and rightinner tabs planar portion 1357 and includeholes Roll pin 1352 aligns in and frictionally engagesholes left tab 1358 and the innerleft tab 1374, respectively.Roll pin 1354 aligns in and frictionally engagesholes outer right tab 1360 and theinner right tab 1376, respectively. Roll pins 1352 and 1354 engage the arrays ofsmooth ratchet teeth resilient material planar portion 1357 of therelease lever assembly 1346 to provide positive spring-like pressure for forced engagement of the roll pins 1352 and 1354 with the semi-circular arrays of smoothedratchet teeth - FIG. 33 illustrates a top view of the pivot/
ratchet assembly 1300. Illustrated in particular is the alignment of the roll pins 1352 and 1354 in therelease lever assembly 1346 with the smoothedratchet teeth arrays U-shaped bracket 1302. - FIG. 34 illustrates a cross sectional view of the pivot/
ratchet assembly 1300 along line 34-34 of FIG. 33. The relationship between therelease lever assembly 1346 and the smoothedratchet teeth array 1312 is described herein. The relationship between therelease lever assembly 1346 and the smoothedratchet teeth array 1310 is similar and is not described for purpose of brevity and clarity. Therelease lever assembly 1346 and an attachedkeyboard tray 1010 are supported by and pivot about pivot stud 1308 (and 1306) and are positionally held by interaction of the smoothed ratchet teeth array 1312 (and 1310) and roll pin 1354 (and 1352). Therelease lever assembly 1346 pivots either clockwise or counterclockwise aboutpivot pin 1350 to position theroll pin 1354 with respect to the smoothedratchet teeth array 1312.Roll pin 1354, being part of therelease lever assembly 1346, is forced and held in engagement between an angled and non-angled portion of ratchet teeth of the smoothedratchet teeth array 1312, as shown in FIG. 35, by the spring-like action of theresilient rubber block 1382 and holds in position and prevents rotation of therelease lever assembly 1346 and the attachedkeyboard tray 1010 and theangle bracket 1328 in a clockwise direction about thepivot stud 1308. Cantilever forces force theroll pin 1354 against the non-angled portion of a ratchet tooth of the smoothedratchet teeth array 1312 for support of therelease lever assembly 1346, the attachedkeyboard tray 1010, andangle bracket 1328. - Counterclockwise rotation of the
release lever assembly 1346, the attachedkeyboard tray 1010, and theangle bracket 1328 about thepivot stud 1308 for upward angular displacemental adjustment of thekeyboard tray 1010 is allowed and effected by manually grasping the outer end of thekeyboard tray 1010 and lifting, thereby causing theroll pin 1354 to be forced, against the spring-like pressure exerted by theresilient rubber block 1382, along the angled portion of a ratchet tooth of the smoothedratchet teeth array 1312, along and about the smoothed tooth end, and into a position between successive angled and non-angled teeth surfaces to a desired position. - Clockwise rotation about
pivot stud 1308 to angularly displace thekeyboard tray 1010 downwardly is effected by depressing therelease tab 1356 to the left, against the spring-like pressure exerted by theresilient rubber block 1382, to pivot therelease lever assembly 1346 about thepivot pin 1350 to remove theroll pin 1354 from influence of the smoothedratchet teeth array 1312 to allow rotational freedom of therelease lever assembly 1346, the attachedkeyboard tray 1010, and theangle bracket 1328 in a clockwise direction about thepivot stud 1308. Releasing of therelease tab 1356 then causes theroll pin 1354 to again engage a position between adjacent angled and non-angled teeth surfaces to secure therelease lever assembly 1346, the attachedkeyboard tray 1010, andangle bracket 1328 against further clockwise rotation. - Elevational rotation of the
support arm 1014 about a pivot support bracket, such aspivotal support bracket 222, in combination with the pivotal positioning of thekeyboard tray 1010 about the pivot/ratchet assembly 1300, as just previously described, offers a great degree of elevational and angular adjustment. - FIG. 35 illustrates in detail the shape of the teeth in the smoothed
ratchet teeth array 1312. With reference to a horizontally alignedradius line 1386 the shape of the teeth is now described.Tooth 1388 includes aflat surface 1392 which is parallel toradius line 1386 upon which vertical forces from thekeyboard tray 1010 are brought to bear throughroll pin 1354 during static operation. Also, lateral forces caused by theresilient rubber block 1382 force theroll pin 1354 into the arcedportion 1394 betweenteeth resilient rubber block 1382 is overcome asroll pin 1354 is forced along and about theflat tooth surface 1396, which is angled or ramped with respect to theradius line 1386. Theroll pin 1354 then traverses thearc surface 1398 at the end oftooth 1390 to be forced by theresilient rubber block 1382 betweenteeth roll pin 1354, between tooth ends is promoted by the use of an arced surface, such asarc surface 1398, instead of abrupt angled surfaces such as are found in other ratcheting devices. Also, less deflection of theroll pin 1354 and shorter actuation of therelease lever assembly 1346 is required to transit between rounded teeth as opposed to using non-rounded teeth whose surfaces form a sharp angle. - Various modifications can be made to the present invention without departing from the apparent scope hereof.
