COLLAPSIBLE STAND.

Application filed December 28, 1923. Serial No. 683,131.

This invention relates to collapsible structures, and pertains more particularly to a portable folding stand which is adapted for use as a support for the detachable seat cushions ot' automobiles and the like.

Motorists who take pleasure excursions in the open country, on alighting from their vehicles upon reaching their destinations, frequently take their seat cushions with l0 them t'o avoid sitting on the ground.' An object ot the present-,invention is to provide a suitable stand or support tor such seat cushion, tofraise the same above the ground to a comfort-able height. t

Another object is to provide a stand or structure .otthis nature which shall be collapsible, so that, when not in use, it can be carried in compact form in the narrow space between the seat ot the vehicle and the cushion resting thereon.

Another object is to provide such a stand which can be adjusted t-o tit seats ot different sizes, thereby obviating the necessity of manutacturing stands in a variety of sizes,

and so materially simplifying their Vmanufacture and tending to their economical production in large quantities. y

@ther objects and advantages Will be apparent as the description proceeds.

in the accompanying drawings forming part oit, this specification, in which like numbers of reference denote like parts where'zverk they occur.

Figure 1 is a plan view oit the collapsible seat cushion support, showing the support folded in at one end andextended at the other;

Figure 2 is an elevational view Vwith a section talren on the irregular line 2-2 of Figure 1; and

Figure 3 is a transverse sectionalview taken on Vthe line 3-3 of Figure 1.

A pair of oppositely disposed angle-bars 1 are connected together, preferably by transverse dat rectangular bars or strips 2, secured thereto by any suitable fastening means s-uchas the rivets 3. There are pret era-bly three such bars, one at each end and one in the middle. The bars or strips 2 consist ot separate mutually over-lapping sections, the outer sections 4 being connected Yby the intermediate section 5. The intermediate section 5 has a series of apertures 6 at one end, which are alternatively reg-V isterable with the series of apertures 7 in Vthe corresponding outer section 4.` The other end of section 5 has a series ot aperturcs` 8, adapted for alternative registration with the series of slots 9 in the other outer section V4. yThe length et the slots 9 is preferably equal to the overall distance across two consecutive apertures 8. Bolts 10, passing through they mutually registerable apertures 6 and 7 and aperture 8 and riot 9, secure the intermediate section 5 to to the outer or end sections 4. The angle bars .1 may be brought closer together or spaced :farther apart by bringing into registration the appropriate opposing apertures in the respective over-lapping sections, coarse variations in spacing by successive stages equal to the distance between consecutive holes being had thereby, and any finer variations desired being eitected by the ertures or tapped holes 18 in bar 15 and passing through apertures 19 in the foot 16 ot one leg and through slots 2O in the toot 16 of the other leg. The series of apertures 19 andthe series otslots 20 are capable of alternative registration with their respective co-operating series oit-tapped holes 18.Y Feet and bar 15 constitute the intermediate span of the U-shaped standard be- `tween its legs 14.

A barj21 preferably pivotedat its center 22 to the center of the middle one of the bars 2 and on fthe underside ot the said middle bar 2, can be swung into either the pos-it-ion shown in full lines 0r to the position indicated by dotted lines in Figure 1.

`Staples 23, secured to thev top` side ot the middle one of the bars 2 `and just inside of the bars-1 andpreterablyparallel thereto, are looped through the eyes 24 of rods or hooks 25, having substantially S-shaped perpendicularly projecting ends 26, adapted to engage the apertures 27 in legs 14 for the purpose of retaining the standards 11 in their normal open positions when the stand hasbeen set up for use.

When folded together and tucked away between the seat cushion 28 and the seat box or cushion support ot a vehicle, the strips 2, and bottom flanges 29 of the angle-bars 1, iace the said seat box, and a rectangular frame 30 on the bottom oi' the seat cushion 28 rests on the top side of the flanges 29, the upright flanges 31 of angle-bars 1 being fitted tightly against the inner sides 32 ot the frame 30, by suitably adjusting the length ot the bars 2, and, ot course, also, the intermediate span otthe U-shaped trames or standards 11. This adjustment is rendered possible because ot the apertures 6, 7, and 8, slots 9, and bolts l associated with the bars 2, and because ot the screws 17 and apertures 18 and 19 and the slots in lei-shaped standards 11, provided for the purpose. It will thus be seen that the seat is gripped securely between oppositely disposed angle-bars 1 and that the latter.l by reason of their adjustable connections, can be moved relatively into and out of gripping engagement with the seat and also adjusted to tit seats ot diilerent sizes. ln this collapsed position et the stand, the standards 11 are tolded in so that their legs le. are parallel to the bars 1, and the said standards 11 are retained in this withdrawn position when the cushion 28 is liiited from its seat box, because of the bar 21 being arranged perpendicularly to the 2 so that its ends 33 support the standards 11. ln Figure 1, the standard 11 at the 'tar side is shown to be thus supported by the bar 21.

lllhen it is desired to set up the stand, the bar 21 is swung to the dotted position depicted in Figure 1, and the standards 11 are then swung outwardly on their pivots to he position indicated in Figure 1 by the standard 11 at the near side ot the stand. The rods or hools 25 are then removed from their withdrawn position on the middle bar 2 (this position tor the associated rods ot the 'tar standard 11 is depicted in Figure 1) and their -shaped bent ends 26 are inserted in the apertures 27 in standards 11. Should the hooks 25 not be used, the standards 11 will be swung farther apart until their legs 14E abut againstthe edges 34 ot recesses 3F in the two outer ones of the bars 2. This, however, results in greater bending strain being placed on the bars 1 when the stand is in use. To facilitate disengaging the hooks 25 from the apertures 2T, tolding the stand together, it is desirable to bend or bow the same as shown at the right in Figure 1. rThis bending permits the preparatory to Y S-shaped ends 26 to wind their way through the apertures 27.

Having thus described this invention, l hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor change may be made therein without departing from the spirit of this invention or the scope of the following claims.

I claim:

A collapsible support tor a seat coin-V prising a pair ot oppositely disposed longitudinally extending seat-gripping members respectively having a horizontal tlange adapted to engage the bottom ot the seat and a vertical frange adapted to engage a side ot the seat, means adjustablv connecting the said members and permitting theV latter to be moved relatively into and out oi gripping engagement with the said seat, and leg members pivotally connected to the said seat-gripping members.

3. A collapsible support lor a seat comprising, in combination, a seat having a rectangular trame on the bottom side thereof, and a' supporting standard comprising oppo- Sitely disposed angle-bars having upright flanges adapted to be engaged with the inner sides of the trame and horizontal flange adapted to extend under theV bottom edges ont the frame, means adjustably connecting the said angle-bars and permitting the latter to be brought closer together or spaced farther apart, and leg members pivotally connected to the said anglebars-V ln testimony whereof l hereunto ai'iix my signature.
