PLATFORM SUPPORT.

Application filed November 8, 1924. Serial No. 748,743.

This invention relates to collapsible tripodal'platform supports for tables, platforms, and the like and has for its objectto improve and cheapen the construction thereof. 7

Fig. 1 is a side elevation illustrating two of the supports embodying the invention and the manner of using them to support a table top.

Fig. 2 is an end elevation of the support.

Fig. 3 illustrates a modified manner of using two of the supports in conjunction.

Fig. 4 is a plan view of the support.

Fig. 5 is an end elevation of the support in collapsed condition.

Fig. 6 is a plan view of Fig. 5.

Fig. 7 is a detail illustrating the manner of pivotally connecting the third leg to the support.

As here shown, the collapsible tripodal platform support embodying the invention includes the three straight supporting legs- 10, 12 and 14 which, when the support is spread into supporting condition, diverge outwardly and downwardly whereby to provide a stable bearing on the floor or other supporting surface.

Two of said legs, as the

legs

10 and 12, are permanently connected rigidly together at their upper ends by the bar 16 and brace 18 to be disposed, when in use, in an approximately vertical plane. Said bar 16 is secured to the upper ends of said

legs

10 and 12, and on corresponding side faces thereof, by suitable means-as screws 20; and said bar extends on opposite sides of said legs for a substantial distance whereby to provide a stable bearing for a table top a or equivalent. Said brace 18 is disposed in spaced relation below said bar 16, and parallel therewith, and is permanently secured rigidly to said

legs

10 and 12 by suitable means as screws 22, and on the same side faces thereof to which said bar is attached. The third leg 14 is provided with a. platform-supporting bracket hereinafter to be described, and said leg with its bracket is pivotally connected with the other two legs in such a manner that it can be swung about its pivotal connectioninto an approximately parallel relation with said legs, in which collapsed condition the support will occupy but little space and can be stacked and transported readily. Said leg and bracket can be also swung into an expanded position at right angles with said other legs, in which position the support is in condition for service.

The pivotal connection for said third leg includes a board 24 of substantial thickness dis osed in the space between said her 16 brace 18 and adapted to engage loosely with said bar and brace. Theupper end of said leg 14 is fixed to said board, on one face thereof, by suitable means as screws 26. Said board is pivotally connected with said her 16 and brace 18 by the

pivot pins

28 and 30, which pins are loosely received in aligned holes in the upper and lower edges of said board; and in the proximate faces of said bar and brace, as is illustrated more clearly In Fig. 7. The upper end of said third leg 14 preferably is extended upwardly above said board and is formed or provided with a'beveled face 32 which is adapted to engage with the side face of the bar 16, in the open position of the support, whereby to hold said leg, in one direction, in proper relation with the fixed legs. \Vhen the leg and board are swung about their pivotal connection, in the opposite direction, to a fully collapsed condition of the support, the board is adapted to lie between the bar 16 and brace 18 and the leg 14 is adapted approximately to overlie one of the fixed legs, or the leg 10, as illustrated in Fig. 5.

Said pivoted third leg is provided with a table supporting bracket comprising afibar 34, which bar is fixed to said board 24, on the same side with said leg, and is extended approximately at right angles upwardly and outwardly from said leg; and the upper and bevelled end 36 thereof is terminated a proximately inthe horizontal plane of t e upper face of said bar 16. As thus arran ed, said bar and bracket cooperate to provi e a triangular support for a table or platform resting thereon. WVhen a long table-board is adapted to be supported, at least two supports will be used, one at each end of the board, as illustrated in Fig.1. The third leg 14 prevents the support from tilting in the direction of the third leg and the weight of the table-board on the bracket 34 prevents the support from tilting in the opposite direction. I I

The connections between the legs of the support are all at the upper end thereof, so that there is a clear and unobstructed space, or foot room, between the legs under the connections; and the legs are edgcwise arranged, whereby further to reduce interference with a person seated atthe table adjacent a support thereof.

WVhen a short table board is to be supported, as the board I), Fig. 3, two supports may be employed and placed with their

fixed legs

10 and 12 in approximate alignment, as illustrated, whereby to form, in effect, afourlegged support.

I claim:

1. A new article of manufacture comprising a collapsible tripodal platform support having three triangularly inclined legs, means disposed at the top-portion of the support fixedly connecting two of said legs and including a platform-supporting bar fixed to the upper ends of said two legs and extended in both directions beyond the upper ends of said'legs, means also disposed at the top-portion of the support pivotally connecting said third leg to said fixed legs, and a platform-supporting bracket fixed to said third leg intermediate its ends and extended outwardly and upwardly therefrom and terminated approximately in horizontal alignment with the upper face of said bar, said support having an unobstructed space between its legs at the bottom portion thereof.

2. A new article of manufacture comprising a collapsible tripodal platform support having three downwardly and outwardly inclined legs, a bar secured to the upper ends and on similar sides of two of said legs and extended in both directions beyond the upper ends of said legs, a brace disposed in spaced relation with and immediately below said bar and secured to the same faces of said legs, a board disposed between said bar and brace and adapted to bear against the proximate faces of both, means vertically pivotally connecting said board with said bar and brace, a platformsupporting bracket fixed to the free end of said board and extended upwardly thereabove and terminated approximately in horizontal alignment with the upper face of said bar, and means connecting the upper end of said third leg rigidly with said pivotal board, said support having an unobstructed space between its legs at the bottom portion thereof.

3. A new article of manufacture comprising a collapsible tripodal platform support having three triangularly-inclined legs, a bar secured to the upper ends and on similar sides of two of said legs and extended in both directions beyond the upper ends of said legs, a brace disposed in spaced relation with and immediately below said bar and secured to the same faces of said legs,

a board disposed between said bar and brace and adapted to bear against the proximate faces of both, means vertically connecting said board hingedly with both said bar and brace, means connecting the upper end of said third leg rigidly with said pivotal board, said leg having an upper portion adapted to engage said bar and limit the pivotal movement in one direction, and a platform-supporting bar carried by said board and extended outwardly and up wardly from said third leg and terminated approximately in horizontal alignment with the upper face of said bar, said support having an unobstructed space between its legs at the bottom portion thereof.

i. A new article of manufacture comprising a collapsible tripodal platform support having three legs, a bar secured to the upper end and on similar sides of two of said legs and extended in both directions beyond the upper ends of said legs, a brace disposed in spaced relation with and below said bar-and secured to the same faces of said legs, a board disposed between said bar and brace and adapted to bear against the proximate faces of both, said board, bar and brace having vertically-aligned holes therein, pivot pins loosely received in said holes, whereby pivotally to connect said board with said bar and brace, means connecting said third leg rigidly with said pivotal board, said leg having an upper portion adapted to engage said bar and limit the pivotal movement in one direction, and a platform-supporting bracket carried by said board and extended outwardly and upwardly from said third leg and terminated approximately in horiiontal alignment with the upper face of said ar. e
