NESTED TRAY STAND Filed Aug. 2, 1962 FIG. I

INVENTORS JULES LISS MARTIN USS ATTORN EY United States Patent 3,100,459 NESTED TRAY STAND Jules Liss, Queens, and Martin Liss, Brooklyn, N.Y. (Both of M71 McDonald St., Brooklyn, NY.) Filed Aug. 2, 1962, Ser. No. 214,307 4 Claims. (Cl. 108-91) The present invention relates to a tray stand unit comprising a stand portion and a tray portion that can be readily assembled, and wherein individual units can be nested or stacked vertically to occupy a minimal storage space. It is contemplated to provide a novel decorative tray stand wherein the stacking means enhances the overall appearance of the device, thus permitting a stacked number of individual units to be kept at convenient near-at hand locations, rather than in closets or storerooms. Novel nesting means are provided to avoid the inherent clumsiness in the method of stacking and arrangement of the units found in conventional nested tray stands.

The device of the present invention is formed of a metal stand portion wherein the legs are secured to a central support member, to which a plastic tray portion is affixed by simple bolt means. It will be appreciated that the conventional low-cost assembly of nested tray stands do not ondinarily contain any element of novely or inherent interest in appearance. It will be appreciated that if this can be attained it will enhance the utility of the device, and consequently attain greater public acceptance.

It is therefore a primary object of thepresent invention to provide a low cost easily manufactured tray stand unit adapted to be nested so as to occupy minimal space in the stacked condition.

. Yet a further object of the present invention is to provide spacing means formed integrally on the tray portion of the device, enabling rapid accurate assembly of the unit to take place. I

These and other objects and advantages of the present invention will be pointed out with particularity or will be apparent from the following description and the drawings appended thereto, in which: FIG. 1 is a perspective view in the exploded condition of a device of the present invention.

FIG. 2 is a bottom plan view of the tray portion of the present invention.

FIG. 3 is an elevation view, partly in sec-tion, of units of the present invention in nesting relationship.

FIG. 4 is an alternate embodiment of the tray portion :of the present invention.

Referring more particularly to the drawings, there is shown in FIG. 1 an embodiment of the present invention characterized generally by the numeral 10, comprising staand portion 12 and tray pontion 14. Stand portion 12 comprises a plurality of [ground engaging leg members 16 mounted upon a central support member 18. A preferred configuration is a three-legged stand since the device is designed to serve as an occasional tray stand, carrying ash trays vases or the like, with little weight normally carried by the unit. a Leg members 12 have radially extending

horizontal portions

19a, 19b, 19c, and downwardly and outwardly extending

portions

20a, 20b and 20c, adapted to engage the ground at the terminal portions 22 thereof. The stand portion may be conveniently manufactured of light steel strips, which are spot-welded to the support member 18. It will be understood that critical tolerances are not needed in a generally low cost device of this type.

Tray portion 14 is a molded plastic member having an upper surface 24 and a lower surface 26 (FIG. 2). Bottom surface 26 has integrally formed thereon a plurality of downwardly depending spacing rnembers herein "ice shown as three pairs of members 28a-2Sa, 28b28b, 280-280, which are adapted to register with and abut the horizontal portions of the

leg members

19a, 19b and 19c, respectively. In the assembled condition, these spacing members are disposed on either side of each of these

horizontal portions

19a, 19b, 190, to prevent angular displacement of the tray 14 relative to the stand 12.

Bottom sunface 26 has formed thereon a second set of downwardly depending spacing

members

30a, 30b and 300, also adapted to register with

horizontal portions

19a, 19b, and 190. However, the second set of spacing members abuts upon and rests on the upper surface of the horizontal portions of the leg members in order to maintain the tray in a plane normal to the axis of the stand portion. An axial bore 32 is formed in central support member 18, and a corresponding downwardly depending hollow cylinder 34 is formed axially on the bottom surface 26. of the tray portion. To assemble the unit, a tapered screw is introduced into the bottom opening of axial bore 32 and thence into the bore 36 of hollow cylinder 34 to threadedly engage the cylinder. Since the tray portion is made of a fairly non-rigid plastic, the screw thread is adapted to out into the inner wall portion of the cylinder and tighten the tray to the stand. In the assembled relation, the tray is maintained in spaced relationship to the stand by means of the first and second set of spacing members hereinabove described, which prevent the tray from moving relative to the stand either in the horizontal or the vertical planes.

As shown in FIGS. 1 and 2, tray 14 is formed with a set of slots 38 which are equal in number to and parallel with the respective horizontal portions of the leg members 19n19c. As shown in FIG. 4, these parts enable the-tray stands of the present invention to be compactly nested with the downwardly extending portions 20a-20-c of the leg members registering with and passing through the slots of the tray stand stacked underneath. It will be appreciated that this forms an extremely compact assembly of tray stands.

Alternatively, for a tray 14 of larger dimension, a

simple notch configuration may be employed, as shown in FIG. 4, wherein the slots tilts-4 .30 do not extend to the edge of the .tray but remain inwardly of the edge portion. This permits of a sturdier structure and also increases the total surface of the tray.

It will be appreciated that the spacing members hereinabove described enable the device of the present invention to be shipped in knock-down condition'and yet be rapidly assembled by the user. The spacing members 28 and 30 place the stand 12 in accurate registry with the tray 14 and also place the slots in correct registration for stacking purposes, as hereinabove explained. The provision for assembly of the unit by a simple screw connection permits shipping of the device at low cost, since it will be in compact, knockeddown form. Also, the spacing members enable the unit to be assembled m a single screw connection, with tray and stand disposed in proper spaced relation to each other. It will be appreciated that this greatly simplifies. the manufacturing process.

There has been disclosed heretofore the best embodiment of the invention presently contemplated and it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit of the invention.
