Abstract

A leg and hinge unit for supporting a table or the like and which permits the leg to be folded beneath the table for storage. The unit includes a U-shaped bracket having a baseplate portion adapted to be permanently secured to the underside of the table with the legs of the U extending therefrom. A support leg is slidably and pivotally secured to the U-shaped bracket by means of pins fixed to the support leg so as to ride in vertical slots located in the legs of the U-shaped bracket. With the table in its horizontal position and the support leg in its vertical position the pins are at the tops of the slots and the support leg is locked in position by means of shallow channel members on the underside of the bracket plate which receive end portions of the support leg. When the support leg is moved to a position substantially parallel to the table, the pins slide downwardly in the slots and the end portions are moved out of the channel members so as to be received in vertical members depending from one side of the bracket baseplate to thus lock the support leg in its horizontal position.

IRVIN HOLLANDER A TTORNE V PAIENTEB JAN! 81972 SHEET 2 OF 2 R m M W IRVIN HOLLANDER ATTORNEY COMEINA'IIGN SUIPFGRT MEMBER AND HINGE LGCIE MEANS BACKGROUND OF THE INVENTION Variously hinged legs sewing as supports for tables and many like structures are known. However, there has been an absence of an economical and easily manipulated hinged leg assembly which would afford certain stability in its supporting function and a locked position thereof whether stored or acting in a supportive capacity.
This invention resides in a particular leg, hinge and locking arrangement not heretofore known, as will be fully described below, and which provides for the leg support structure two lock positions with a sturdy and simple arrangement utilizing a minimum number of parts.
FIELD OF INVENTION This invention has particular significance in camping trailers and the like wherein space is at a premium and wherein it is desirable to have tables and the like which can be folded out of the way for travel and extended for use. It will be apparent, of course, that the invention may be utilized in a great many conditions and circumstances other than that just indicated although this was the original concept.
SUMY OF THE INVENTION The invention embodiment provides a support structure including a leg and hinge arrangement whereby the leg may be locked in its vertical supporting position aided by the applied load which it supports. By raising the load and pulling the leg therefrom a small amount as here provided, the leg may be readily folded to a substantially horizontal position for storage, the hinge means which permits this having means to lock the leg in its stored position. The arrangement is achieved with a minimum number of parts disposed with utmost simplicity. It provides for the leg two locking positions with a very durable construction.

DESCRIPTION OF THE INVENTION Referring now to the drawings, while FIGS. 1 and 2 show an embodiment of the invention supporting a table 20, this is for purposes of illustration only. The invention leg and hinge unit may be applied to any member having a substantially horizontal position when in use and a substantially vertical position when not in use. Such a member, particularly with reference to camping trailers and the like, a sidewall of which is indicated at 21, could just as well be a cutting board, a wash basin, any kind of a table, an ironing board or even a bed.
The table, as the member will be referred to henceforth throughout this description, is shown as connected to the wall 211 by a block 22 and a conventional hinge 23 respectively.
Referring to the invention assembly, its hinge comprises a U-shaped bracket generally indicated at 24 in FIG. 3 and including a narrow, elongate, flat, baseplate portion 25 having turned-down ends 26 and 27 which are shown to depend vertically, at right angles thereto. The baseplate portion 25 has a number of apertures 23 by means of which it may be fastened to the underside of the table 20 by screws, as indicated in FIG. 5. Each of the ends 26 and 27 has formed therein an identical and similarly positioned vertical slot 29.
Equidistantly spaced intermediate its ends, the base portion 25 includes two blanked out portions 30 each of which has a generally rectangular configuration. Each of the blanked out portions 30 is so formed and stamped to produce in the process a pair of divergent plate segments 31 turned down on parallel lines spaced between and parallel to the side edges of the baseplate 25. This provides at the underside of the plate portion 25 and between the ends as and 27 a pair of aligned shallow locking channels the sidewalls of which are formed by the segments 311.
As seen in FIG. 3, one side edge of the baseplate portion 25 has formed integral therewith and bent to depend vertically therefrom a pair of spring fingers 32. The fingers 32 are longitudinally spaced, aligned and their upper portions are bent slightly inward between the ends 26 and 27 while their lower dependent extremities are each bent outwardly and curved back to form an arcuate cup 34 which opens inwardly of the bracket 24. The fingers 32 provide means for locking a support leg 33 in a folded position in respect to the table 20. The dependent cup portions of the spring fingers are shaped to conform to the configuration of those portions of the leg with which they will coact. This will be further described.
The support leg 33 has been illustrated in this instance as comprising a continuous tubular member bent into a generally U-shaped configuration. Its closed end portion 36 forms a sup porting base from which its leg segments 35 project upwardly in a slightly divergent relation. The uppermost ends of the leg segnents 35 include flatted right-angled portions 38 bent inwardly towards each other and terminating in coaxial tubular portions 40, the adjacent ends of which are spaced. Note that the portions 38 and 410 are preferably defined by integral portions of the leg segments 35. However, they may be separately fabricated and welded together where circumstances so demand.
Each flatted portion 38 has in the part thereof forming an immediate direct extension of the tubular leg segment 35 a similar and identically positioned aperture 44. In assembling the leg unit 33 to the bracket 24, the flatted portions 38 of the upper ends of the divergent leg segments are disposed between the bracket ends 26 and 27 to align the apertures 44 with slots 29. The leg unit 33 is thus slip fit within the bracket to bridge the space between its ends and thereafter a headed pin it is inserted through each slot 29 to have the head 12 thereof abut the outer surface of the related end portion of the bracket. The body of the pin passes through the aligied aper ture M in the flatted upper portion of the adjacent leg segment 35. A tubular rivet body 33 is fixedly applied to the inwardly projected end of each pin 41 whereby to contain the leg segment 35 in a pivoted slidably adjustable relation to the bracket 24. As will be obvious, the ends of the slots 23 determine the limits of movement therein of the pins M and thereby of the leg unit 33.
OPERATION When the support leg 33 is in its vertical support position of FIGS. 1, 2 and 4, the pins 411 are respectively positioned at the tops of the vertical slots 29 to which they relate. This is best seen in FIGS. 5 and 7. Under conditions of vertical load on the leg 33 here illustrated, the upper terminal tubular leg portions 40 are identically and respectively seated within the channels defined by the pairs of divergent plate segments 31L The weight of the table and its load, perhaps with an assist from the user, will insure this position being achieved. In this position the tubular portions d0 frictionally wedge between the upwardly convergent surfaces of the segments 31 which define the locking channels. The support leg unit 33 is thus secured against any pivotal movement.
In order to fold the support leg unit 33 under the table 20 and hold it there, the user will lift the table a small amount as permitted by the hinge 23 and pull the support leg unit 33 downwardly from its frictionally wedged position until the pins 41 are drawn to the bottom of their respective slots 29. When the pins 41 are so bottomed, the terminal portions 40 are just clear of their respective wedging channel forming bracket segments 31, as best seen in FIG. 8. The leg unit including its segments 35 may now be rotated, clockwise as viewed in FIG. 8, until the unit is substantially parallel with the underside of the table 20. As this leg moves to the position of FIG. 9 (and dotted line position of FIGS. 1 and 6), the terminal portions 40 will first engage the inwardly slanted upper portions of the vertical spring fingers 32, at about areas 32a thereof adjacent the cupped portions 34. This causes the spring fingers, which are slightly resilient, to move in a counterclockwise direction, noting FIG. 8. Continued clockwise movement of the support leg unit 33 and portions 40 thereof will permit the resilient springfingers 32 to snap back to their original positions and the cup portion 34 to frictionally engage about the terminal portions 40 of the leg unit in a manner to lock the same in its stored or folded position as seen in FIG. 9. As this final action takes place to create a locking of the leg unit in its stored position, the pins 41, due to a form of lost motion movement, may ride slightly upward within the slots 29 as the members 40 engage and pass over the areas 32a of the locking member 32. This is also illustrated by the dotted line position of FIG. 6. The leg is now locked in a folded dotted line position shown in FIG. 1 and the'table 20 may now swing to the dependent dotted line position of FIG. 2.
To return the support leg unit 33 to its vertical position, the table 20 is swung back to its horizontal position and the leg unit is moved in a counterclockwise direction as viewed in FIGS. 1 and 6. In so moving, the terminal leg portions 40 will ride over the areas 32a of the spring fingers, forcing the fingers in a counterclockwise direction (FIGS. 6 and 9) and as the pins 41 first bottom in the'slots 29, whereafter, when the leg unit 33 is substantially vertical, the table 20 may be pushed downwardly so that the pins 41 abut the tops of slots 29, the leg section 36 engaging the floor 37 under the table. In the process the portions 40 of the leg unit will be wedged in locked position within the upper converging portions of the locking channels defined by segments 31.
It will be apparent to those skilled in the art that modifications may be made in this invention without departing from the scope and spirit thereof and although the invention has been described and depicted as comprised of certain particular structures and arrangements, these are not to be considered as a limitation on the invention except insofar as they are specifically set forth in the appended claims.
From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect.
