Definitions

• the invention concerns adjustable beds and provides improvements for proper adjustable support to serve better medical and comfort requirements.
• An improved adjustable body supporting assembly which is distinguished by its capability to rpovide with a single power means the movement of a support and the additional movement of a pivoting second support portion in relation to the first such as the head serving upper back support portion by means of linkages to the base and a improved adjustable body supporting assembly which is distinguished by single power means moving the lower body supports from a horizontal to an upward slanted position of the leg support in combination with the aligned knee support, and of moving the leg support from its slanted elevated position through a horizontal position at an angle to the knee support to a position with the leg support pivoted downward for an regular sit-up position, and embodiment combining both the improved head and knee-leg feature.
• a variation of the embodiment serving for treatment, human activities or cardiovascular problems has power driven separate sides, each composed of a leg and knee support, adjustable to different levels and angles and/or programmed for movement simulating walking movements to facilitate the hearts activity.
• the invention is also providing for more compact adjustable assemblies, moving from a wall hugging sit-up and elevated position to a full lenght bed.
• the embodiments also include an improved mode of operating a built - in toilet .
• serving for human activities is provided with separate adjustable lower supports, to facilitate various positioning or two occupants.
• Providing an adjustable body supporting assembly with a single power means operated knee and leg supports system is accomplished by such simple expedients as connecting the pivotal connections of the leg support to the knee support and also if desired, connecting the pivotal connection of the knee support to the middle support, with spring loaded hinging means and mounting one end of the power means to the leg support and the other end of the power means of the supporting panel or frame.
• the power means such as a fluid operated cylinder and piston or a motor driven screw is extended from its shortest position, in which the leg support can be pulled downward and below a horizontal body supporting level, the leg support will be raised while the knee support remains in an angled pos ition in relation to said knee support, until the leg support is aligned with the knee support.
• the spring loaded hinging means secures now the leg support to remain in an aligned position with the knee support and the retracting powermeans lowers the aligned knee and legg supports until it reaches a level position with the body supporting assembly, at which position the knee support is stopped by restraining means, and further retracting of the powemeans causes now the leg support to continue downward, facilitating sitting-up and entry or exit.
• a mattress wound around the leg-rest end serves for aninterrupted support.
• a further variation of this improvement provides entirely new important results in the form reduced space requirements, single power operation of the whole adjustable support assembly, and an elevated sit-up position which facilitates getting in or out of the assembly.
• the push and pull rod extends in a simpified variation from a downward extention of the backsupport to the leg support, which in turn is pivotally connected to a knee and middle support.
• Said middle and knee support is mounted on pivoting arms to the base, and the back support is also mounted on pivoting arms to the base, while pivotally connected to the rear end of said middle support, in a manner that a push on said push and pull rod causes the backsupport to move from a vertical position through reclining positions to horizontal positions.
• the middle support moves forward, and the leg support is moving from a vertical position to through various positions of slant to a horizontal position.
• the height of the sit-up position can be predetermined by the length and pivotal positioning of the pivoting arms connecting the middle and kee support to the base.
• the leg support can be divided into transverse portions, pivotally connected to each other.
• the said transverse portions are connected with linking arms in a manner which causes a retracting pull of the rod to fold the lower portion of the leg support inward, and a pushing movement to fold said lower portion out when the leg support is elevated.
• the arm connecting the said rod to the upper leg support portion can extend with a cas ter to the floor when leg rests fold out.
• one power means serves for the adjustment of the knee support and the leg support together or to change their relative position to each other, and also accomplishes a sit-up position for the whole body supporting assembly is of special importance when said assembly is provided with a built-in toilet, as a sitting up position serves to facilitate the bowel movement.
• the built-in retractable toilet has been improved to require only a relative low height of the body supporting assembly off the floor.
• the use of one power means for two purposes of body position adjustment by means of improvements of the mechanism holding and moving the supports is a special importance in the creation of a separate movement of the occupants head by means of a linkage of a separate head support portion pivoting form the adjustable backsupport.
• the linkage is pivotally mounted to the frame serving as base, in a manner which gives the linked head support an elevating movement in relation to the backsupport, when the backsupport is elevated, and the more the backsupport is elevate the more the head supports begins to incline forward, thus producing the required positioning and angle for a occupants head when engaged in activities such as T.V. viewing or reading.
• an adjustable body support assembly with three adjucent lower assemblies will facilitate many important human activities, which require not only elevating positioning but also the lowering of a support area. Variations of this assembly will serve for improved family life, while other variations can serve to provide for the insertion of a bedpan in the lowered area, thus facilitating the requirement when necessary.

• a fluid operated cylinder 4 is shown mounted pivotally at 3 to the member 2.
• a pushrod 5 isextending from the piston in the cylinder 4 and is in turn pivotally mounted at6 to an downward extending member 7 of the leg support 8.
• This legsupport is pivotally connected by a springloaded hinge 9 to the knee support 10 which is pivoting at 9.
• the pushrod 5 retracts and causes the legsupport to pivot downward creating a sit-up position as shown in Fig. 2.
• leg support Is now the fluid directed into the cylinder for an outward stroke the leg support is pushed upward while because of its springloaded hinging mounting, retains an angled relation to the knee support 7 as in Fig. 3 until said knee support is restrained as in Fig.4. The raise continues until a springloaded pivoting mechanism 9 snaps the supports 8 and 10 into an aligned position shown in Fig. 4. Is the fluid now directed for inward stroke, the leg support with the presently aligned knee support will move downward into a horizontal position, as in Fig.1. The knee support 10 is restrained from further downward movement by the frame 1 and thus when further inward flow is provided to the piston and rod, the leg support will pivot downwards.
• the same power means serves for a body supporting assembly with two separate lower body assemblies of pivotally connected knee and leg supports, as shown in Fig. 6,
• the left side leg support 12 and the knee support 13 is raised in common alignment while the right side leg support 14 is lowered from its spring-loaded pivoting point 15 mounted to the right side knee support 16.
• the powermeans, in this case shown as a fluid driven piston 17 serving for the left side movements separately is pivotally mounted to the frame member
• Adjustment of usual type cut-outs as provided in many mototized screw drives would limit the length of the stroke, and when fluid operated drives are used, the amount of fluid and pressure could be regulated to provide a stroke of a desired length and the following reversal of movement.
• cut-out 24 and 26 are shown activated by an adjustable member 25 or 27 to provide a limit to the desired stroke of the respective supports and also serve for the alternate movement of each side and reversal of stroke.
• a base 28 has been added to the supporting frame or panel 29 and is connected to said member by pivoting arms 30 and 31 at 32 and 33, and power drive 39.
• One arm 30 is composed of two members 34 and 35 which slide in each other and are provided with a securing screw 36. Using the power drive 39 and loosening the screw 36 will provide a lenghtening or shortening of arm 30 and create a desired slant of the body supporting assembly, once the screw 36 is secured for a desired length of the arm 30.
• the arm 30 could be extended with a screw.
• a motorized screw drive 39 is pivotally connected to support panel 29 and with its other end to base 28 at 41, and serves for the adjustable elevation.
• Figures 9 and 10 show an embodiment in which the adjustment of all pivotally connected body supports from a bed-like horizontal position through variable reclining postions to an elevated sitting position is achieved by one single power stroke and vice versa, and within the additional space saving feature of the whole assembly retracting into a sitting position of less than half the length and remaining stationary near a wall.
• a backsupport 44 is pivotally connected to a middle support 45 at 48.
• a pivoting arm 49 connected at 51 to member 43 of the base 42 is mounted pivotally at its other end to the back support at 50.
• the middle support 45 serves as support panel similarily fo frame or panel 1 in Fig.1-6 and is supported by arms shown as 52 and 53 which are pivotally connected at 54 and 55 to the support45, and at their other ends to the base 42 at 56 and 57.
• member 47 serves of a pivotal connection to member 59, which in turn is pivotally connected at 58 to members 61 and 63 which are pivotally connected respectively at 62 to the upper leg support portion 46 and to the lower portion 65.
• An elgonated armrest 68 is seen behind the middle support
• leg type extension member 74 of the arm which with its attached caster 75 moves downward to support the extended assembly.
• FIG. 14 A further variation of this embodiment is shown in Fig. 14.
• the power drive is replaced by a mechanism similar to these employed presently in recliners assisted by means such as springs or gas filled cylinders whereby the occupant provides for the movement by moving certain parts of the body and/ or a supporting push or pull on the armrests 68.
• Fig. 11,12,15 a design of a new type fo toilet is seen composed of a lower portion 69 which contains a bowl 70 connectied by an traplike feature 71 serving to restrict odors from the flexible hose connection 72 and the wall outlet 73.
• the toilet shown here in its retracted position has reached with its upper portion 74 made from material such as hardened foam in Fig.
• a pivotally connected cover 75 which is, by the continued retracting movement of the toilet forced into a horizonta position enclosing the opening of toilet, at the same time a spring loaded lever is pushed activating a programmed water flush into the toilet bowl 70, said flush originating from a flexible hose connection to a water main outlet.
• Said upper portion 74 of the toilet serves mainly as rim for the slit like opening, as the mattress itself serves as seat instead the seat of conventional toilets, and is made of disposable material so that it can easily be replaced when dirtied or when occupants change. It is as shown in Fig. 11 formed with an protuding part 74 and is held in position on the toilet by being pushed in and held by a protruding part 76 of the toile A deflector-type part 75 is extending upward from said upper portion 74 and serves to deflect a possible forward directed flow downward, however also, as a positioning means. For it is evident that an upward movement of the toilet into the mattress opening will cause said deflector type extension 75 to extend between the. legs of an occupant.
• slit sides 81 and 82 provide in this improved version the seating support and reduce the size of the opening, for the occupant actually remains seated on the mattress.
• a new improvement developed eliminates such system by using one power stroke to move both the toilet and vacate a slit by the simple expedient of a connecting member 85 serving as push and pull rod and connected either indirectly as in Fig. 15, to the power drive 86 is used to provide a pulling movement on sides 81 and 82 by such means as pulling a sheet like material, 89 by means such as clamps 90 & 91 in scissor like form apart.
• the slit is widened by means such as specially formed parts 92 and 93, whose upper end stick into the lower part of the slit 80 of the mattress 94.
• Parts 92 and 93 are pivotally mounted to the bottom side of the mattress support 95 at 96 and 97 respectively.
• FIG. 18 and 19 An improved adjustable body support assembly is shown in Fig. 18 and 19.
• the backsupport 101 is divided transversely into an lower portion 102 pivoted at 103 to the base frame 104, and into an upper portion 105 pivoted to said lower portion 102 at 106.
• a support frame 107 shown in Fig. 18 is made up of long members 108 and connected by member 110.
• This member 110 is provided with an downward extention 111 into which one side fo a screwdrive 112 is secured at 113.
• the other side of the screwdrive is secured to member 114 of the simplified base frame 104 to provide an elevating movement to the back support 102 lifting at the same time the upper portion 105.
• An downward extention 115 of the said upper portion 105 is connected at 116 to a link 117 which is pivoting at 118 to the baseframe, and thus causes the upper support portion 105 progressively to incline forward when power means 112 pulls this support upward.
• the linking member 120 is pivoted at its one end to the leg support 119 and to the base from 104 with one of the pivoting holes
• This hole and the corresponding pivoting hole in the base frame 104 are distanced so as to achieve a complete horizontal alignment of the leg support 119 with the knee support 118, when said knee support is lowered by of the power drive 122. While the leg support is in its flat and aligned position with said knee support the pivoting bolt can be transferred to another set of corresponding pivoting holes in both the linking member 120 and the base frame 104, and thus produce a desired different movement of the leg support 119 in relation to the knee support 118. As shown also in Fig.
• Fig. 20 & 21 To overcome the moving of the mattress when the adjustable supports are operated the improvement of securing the mattress to the frame is shown in Fig. 20 & 21.
• a wide strap 122 is attached to both edges 123 of the mattress, and its median position extends outward as flap 124 which can be attached to the bolts 125 sticking out below the base frame 104.
• a wide strap 126 is attached to the upper mattress dege 123 at one side and to lower edge of the mattress at the other side, permitting mattress reversal.
• a body supporting assembly comprising adjacent adjustable assemblies for each side is shown with the additional median lower assembly whose knee support 132 is turned downward forming together with lowered leg support 133 a lower level facilitating human activities and or insertion of a bedpan.
