July 28, 1959 G. M. ELLMAN COLLAPSIBLE STAND Filed June 1l, 1958 :Ill

lill Z United States Patent COLLAPSIBLE STAND Gilbert M. Ellman, Chicago, Ill., assignor to Aristo-Craft Products, Chicago, Ill., a partnership Application .lune 11, 1958, Serial No. 741,411 7 Claims. (Cl. 45-121) This invention relates to collapsible stands or rests for supporting music sheets, papers, [books and the like.

It is a general object of the invention to provide a new and improved stand of the type described.

Another object is to provide a new and improved music stand of light weight materials which may bereadily collapsed into a compact unit convenient for carrying and storage and which may be easily unfolded for use as a sturdy support.

A more specific object is to provide a new and improved music stand of the type described including a collapsible leg structure and a foldable rest structure, the latter having one portion permanently joined to the leg structure and another portion connectalble to the leg structure for holding the stand in an upright unfolded condition.

The particular embodiment of the invention chosen forJ illustration is intended primarily for use by musicians in Ibands or orchestras for supporting music sheets in front of the seated musician; it is particularly adapted for such use because it is readily collapsible into a compact unit convenient for carrying by hand or other transportation during movement from place to place. However, it will be understood the utility is not limited to that described. i

The invention is illustrated in a preferred embodiment in the accompanying drawings, in which:

Fig. l is a front elevational view of the stand disposed in an unfolded upright position;

Fig. 2 is a side elevational View of the stand as illustrated in Fig. 1;

Fig. 3 is a front elevational view of the stand in collapsed condition; and

Fig. 4 is a side elevational view of the stand as illustrated in Fig. 3. i

Referring now to the drawings in more detail, in a preferred embodiment, a stand incorporating the principles of the present invention includes a collapsible leg structure generally ydesignated and a foldable rest structure generally designated 11. The leg structure 10 comprises a iirst or inner inverted V-shaped leg iframe 131 including a pair of separate legs 14 and 15 having lower ends spaced rather widely apart and adapted to rest on the door and having upper ends joined as at 16 at the apex of the frame. If desired, the lower ends of legs 14 and 15 may be provided with suitable rubber-like shoes as at 17. A second or outer V-shaped leg frame 18 has separate legs 19 and 20 including upper ends which are rather widely spaced apart and lower ends joined as at 21 and adapted to rest on the floor.

Intermediate portions of the leg frames 13 and18 are pivotally interconnected as by having each leg of the outer frame 18 pivoted on one leg of the` frame 13:. In the preferred embodiment illustrated, legs 19 and 20 of the outer frame 18 are pivotally connected respectively to the legs 14 and 15 of the inner frame 13 as Iby pivot pins 23 which may take the form of bolts, screws or rivets. At the pivots 23, legs 19 and 20 of the outer frame 18 pass outwardly of the legs 14 and 15 of the inner frame 13.

If desired, the pins 23 may be removably mounted, and the respective legs of the two frames may be provided with a series of holes which enable an adjustment of the pivotal interconnection to vary the effective height of the stand. Preferably, the outer frame 18 is provided with a plate or disc as illustrated at 25 suitably secured to the frame legs as at 26 and providing a support for an emblem or other indicia for identifying a particular band or orchestra.

The rest structure 11 is comprised of two portions, a first portion in the form of an elongated plate 27 secured adja-cent opposite ends to the upper ends of the legs 19 and 20 of frame 1S as at 28. As illustrated, the second rest portion comprises a plate 30 of a length comparable to that of the plate 27 and of a substantial width in a front to rear direction as will be apparent on viewing the drawings. The second rest portion 30 is pivoted to the lower edge `of the rst rest portion 27 as by a pair of hinges seen at 31. Adjacent its upper edge, the rest portion 30 has a centrally located opening 33 therethrough adapted to tit over the upper end of the inner leg frame 13 when the stand is in the upright unfolded position illustrated in Figs. l and 2.

The opening 33 provides the second rest portion 30 with a hook-like means adapted to latch over the projecting end 16 of the frame 13 for securely retaining the stand in the upright position of Figs. l and 2. In this position, as seen in Fig. 2, the frames 13 and 18 are inclined from the vertical and cross each other at the pivotal interconnection 23, so that the leg frames provide a three point support at 17, 17 and 21. ln this position of the stand, the rst rest portion 27, of course, lies substantially in the plane of the outer frame 18 to which it is attached, and the second rest portion 30 extends upwardly and rearwardly from the lower edge of rest portion 27 toward the upper end of the leg frame 13.

. Due to the inherent weight of the stand, it will .-be apparent that the lower ends of the leg frames cannot pivot toward each other, and due to the latching of the rest portion 30 over the upper end of leg frame 13, the frames are prevented from pivoting in the opposite direction, so that the stand is rigidly disposed in the position illustrated to provide a sturdy support for music sheets, and the like.

The stand is readily collapsible from the position illustrated in Figs. l and 2 to the compactly folded position of Figs. 3 and 4. Collapseof the structure is effected by simultaneously pulling upwardly on the upper rest portion Si] while pivoting this portion in a counterclockwise direction as viewed in Fig. 2 to release the rest portion 30 from the upper end of frame 13. After this release, the outer frame 18 rnay easily ibe pivoted in a counterclockwise direction as viewed in Fig. 2 to dispose the outer frame 18 in the plane of the inner frame 13 in the manner illustrated in Figs. 3 and 4, with the inner frame nested within the outer frame 13. Such movement disposes the rest portion 27 against lower portions of legs 14 and 15 of the inner frame 13, and the upper rest portion 30 may be pivoted to lie against the leg portions` of both frames as seen in Figs. 3 and 4. Preferably, the disc or plate 25 is provided with a latch or other fastening means illustrated at 3S, pivoted at 36 and adapted to releasably latch over the edge of rest portion 30 to securely retain the stand in the collapsed position illustrated. Such latch means securely holds all the parts of the stand in the position shown so that `the stand may be gripped by `handy as at the portions 16 or 21 for carrying.

In the preferred embodiment illustrated, the leg frames 13 and 1S are comprised of tubular aluminum or similar lightweight materials, and the rest portions 27 and 36 may be comprised of light-weight metal material or of pressed berboard or similar materials so' that the entire weight of the stand is negligible and readily portable.

The foregoing detailed description is given for clearness of understanding only and no unnecessary limitations should be understood therefrom as modifications will be obvious to those skilled in the art.
