Application October '27, 1949, Serial No.123g826- ,5 Glaimsl This invention comprises novel and useful imprevem ents ina stand and more specifically pertains to a collapsible stand having improved means for retaining "the parts in their assembled and in their collapsed positions as desired.

The principal object-oi this invention is to provide an improved construction of stand which may "be employed for a support for various articles, and which shall have an "improved construction permitting ready collapsing or folding of the stand into a compact position for storage or for assembling into anoperative position.

A further object of the invention is 'toprovide an improved'stand in conformity with the foregoing object wherein the 'legs of the stand are I provided with improved means for selectively locking the same into their operative andinoperative positions.

Yet another object of the invention is to provide an improved-stand which shall be of a simple and inexpensive construction, yet sturdy and highly efilcient for the purposes intended.

These, together with various ancillary features and o'b j ects of'the invention which will later become-apparentas the followingdescription proceeds, are attained by the present invention, a preferred embodiment of which has been illustrated, by way of example only, in the accompanying drawings, wherein:

natezsimilar parts: throughout-the. various. views, attention is directed first to theembodimentpf 'FFgures 1-14, :6, '7, in which it will be seen that the foldable: stand iorm-ing'the subject :of this invention consists ofra pal-r; of concentric; inner and outer tubes; or sleeves, Jill and ill, which .are relatively slidable with respect to :each other. The lower end of the outer tubeior sleeve :12 is provided with a closure cap orxhase 2114; havingan upstanding annular wall I56 which is received within-the lower :endof the outer sleeve 12 and secured thereto in. any desired manner. The upper surfaceof this annular-wall. 1B of the base it, constitutes a seat or abutment upon which the lower-end of the inner sleeve l t! mayrest.

Embracing the bottom portion of the exterior surface of the outersle'eve I2 is ametal strap or band I8 which is clamped or otherwise fixedly secured to the outer sleeve inany suitable manner, this band having a plurality of radially extending pairs of apertured ears Zllbetween which are pivotally'attached supporting legs 22 of the stand.

As shown best in Figure 7, these legs may convenien'tly comprise tubular rods having flat portions 25 at their innerends, these flattened portions'being apertured as at 26 for'the reception of pivotpins 2-8by means of which the flattened "portions are pivotall-y secured between the pairs of ears 29. By this means, the legs are mounted for 1 Adjacent its hinged extremity, each leg 22 is preferably providedwitha laterally extending lug 3|] which adjacent the leg 22 is provided with a slotted portion '32 by means of which the leg may be locked in its-closed or folded position, and with a laterally extending surface '34 constituting an abutment-surface'by means of which the leg'may be locked into its opened or-oper-ativeposition.

The outer sleeve 12 and the annular wall or rim it of the base secured therein; are provided with vertically extending slots 36 which are adapted to receive the lugv 30"when the leg is folded into itsv closed-position.

Freely and slidahly received upon the outer sleeve I2 is a retaining or looking sleeve member 38, having an annularly enlarged apron-like lowerport'ion 40 which 'isradapted to embrace the flattened end portions 42 ofeachof the legmembersinthe'ir raised position as shown'in Figure .2

"to thereby retain and lock these legs in their collapsed arrangement. At the same time, the lower edge of the inner sleeve III in its lowered position will engage in the notches 32 of the legs in their folded position, as shown in Figure 2, whereby 3 the legs are locked at both their extremities and the entire stand is thus retained in its collapsed position. 7

It will now be seen that in order to convert this stand from its folded or inoperative position shown in Figure 2 to the operative position of Figure 1, it is merely necessary to raise the retaining sleeve 38 whereupon the apron portion 40 will disengage its locking embracing of the ends of the legs, and upon raising of the inner sleeve l0, whereby the lower end of the same will be disengaged from the slots 32, the legs will pivot vertically by means of their own weight to their horizontal position shown in Figure 1. At this time, the retaining sleeve may be dropped to its lower position, whereupon the exterior surface of the apron 40 will be disposed against the abutment surface 34 of the lugs, thereby preventing the legs from raising above their horizontal posi-' tion. At the same time, the hinged extremities of the legs which are arcuately shaped as at 44, will engage the regularly extending stops or abutments 46 formed upon the rim portion it of the base, these stops extending through the above mentioned longitudinal slots 36. The engagement of the abutment surfaces 44 of the legs with the stop members 46 will prevent pivotal movement of the legs below their horizontal position. Thus, the legs will be securely locked against upward or downward pivoting movement, thus forming a very rigid and sturdy stand which may be employed to support any desired type of article.

Alternatively, the construction illustrated in Figures 5, 8 and 9 may be employed. In this form, the same construction of concentric inner and outer sleeves l2 and I may be employed, together with the retaining sleeve 38 having the retaining apron 40 thereon. Likewise, the annular clamp l3 having the pivots 28 for pivotally connecting between the pairs of radially extending pairs of ears to vertically pivoting leg memhere 50 may be employed. These leg members, however, as shown in Figure 9, are provided with flattened extremities 52, and curved abutment surfaces 54 and a pivot aperture 56, have omitted therefrom the locking lugs of the previous embodiment. Instead, a locking notch 58 is provided adjacent the pivot end of these legs, which at their other extremities are flattened in the same manner as the legs 22 at the ends 42 as shown in the preceding embodiment. In this embodiment, the legs are retained in their lowered, horizontal or operative position by engagement of the lower end of the apron 50 of the retaining sleeve 38 in the above mentioned notches 58; which thus positively prevents either upward or downward pivoting movement of the legs and locks the same in their operative position.

In the folded position, the legs are retained merely by the flattened outer end portions of the same being embraced by the apron 40 of the retaining sleeve 38. 4

From the foregoing, the advantages arising from the novel construction of the device, together with this operation will be readily understood by those skilled in the art after a consideration of the foregoing specification and accompanying drawings,v and accordingly, further explanation isbelieved to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after 4 a consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
