7 Claims. (Cl. 312-255) This invention relates to a novel slidable shelf or tray adapted for use in a supporting stand or cabinet.

It is an object of the present invention to provide a slidable shelf or tray of novel construction, suitably composed of metal, together with means for support and engagement thereof on, for example, a supporting stand where it may be used as an auxiliary for a filing cabinet.

It is a particular object of the present invention to provide a novel combination of a tray or shelf of the class described and decorative edge finishing trim or molding therefor secured together in a novel construction and arrangement.

Other objects and advantages of my invention, the economies thereof, and the construction and arrangement of parts will be apparent from a consideration of the following specification and drawings:

Fig. l is a perspective view of a stand and sliding shelf embodying the present invention.

Fig. 2 is an enlarged fragmentary section on the line 22 of Fig. 3.

Fig. 3 is a plan view of my assembly with parts in section.

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 is a perspective fragmentary exploded view of the novel shelf of the present invention.

Referring to the drawings, reference numeral generally indicates a four-legged tubular stand provided with a slidable shelf in accordance with the present invention, and generally adapted to hold cabinets such as record cabinets, although it will be understood that the present invention is not limited thereto.

Thus, the stand comprises four legs 11, although there may be six or any greater number arranged in rectangular fashion, secured together by a brace generally indicated as 12, mounted on suitable caster and roller assemblies 13. The stand further comprises a pair of

angle members

14, 14 immediately above the

transverse braces

15 and 16 for supporting a device such as a record card tray cabinet or other object. Mounted on the stand is a slidable shelf or tray 17.

It will be understood that although I have illustrated a tubular stand, so far as the present invention is concerned the stand may comprise a cabinet and need not be adapted for supporting a cabinet thereabove as on the

angle irons

14, 14. 1

Secured to an opposed pair of tubular supports 11 is a bracket serving as a slideway or track composed of a flange portion 18 welded or otherwise secured between one pair of tubes 11. This bracket is further bent normally thereto so as to form a substantially U-shaped bracket 19 having an inturned end portion 20 extending above the flange 18 and projecting toward the leg 11. It will be understood that a pair of these brackets are provided, one at each opposed side of the supporting stand 10.

The slidable tray adapted for engagement with the aforesaid track may be conveniently composed of a sheet of metal 21 notched at at least its two forward corners in a rounded manner as at 22 shown in Fig. 5, and with States Patent at least its sides or, in the present instance, both its sides and forward edge, return-bent in U-shaped manner to provide a forward face 23 and an inturned leg 24.

The rearward end of the sheet of metal 21 may be bent downwardly but need not be returnsbent as at 25.

Secured at least to the two side edge portions and desirably also to the forward edge portion at'the bottom of the metal sheet 21 are Z-shaped brackets generally indicated as 26, each of which comprises a leg or flat 27 which is secured as by welding to the underface of the metal sheet 21. The other leg or flat 28 o-f't-his Z- shaped bracket extends in plane parallel spaced'relationship to the inturned component 24. This leg or flat end 28 terminates in a U-bend 29 normal thereto, having one outer face 30 in alignment with the component 23 extending from the sheet 21.

The U-bend 29 is adapted to be received in the U- bend 19 secured to the supporting base for inter-locking slidable engagement, the component 29 forming a slide and the component 19 forming a runway or track.

For covering the exposed edges of the tray component 21 I provide unitary molding in the form of a strip which may be of aluminum having a dmorative outer surface 51 and a medial flange or arm 32 which may be of serrated or notched form as shown in Figs. 2 and 4. This notched leg or flange is continuous of the molding strip 31 except where it is removed (not shown) when bent, for example. at the corner 33.

In forming the assembly of the tray, the molding 31 is adapted to extend slightly above the top of the base sheet 21 to provide a seat for the finishing surface 34 which may be of linoleum, vinyl resin or other plastic, leather, or other sheet material.

In assembling the components the tray is slid onto the supporting stand with the U-bend portion 29 received in the -U-bend portion 19 against a stop member, not shown, at which time the molding strip 31 is moved into place so that the serrated arm 32 becomes disposed between the flat 28 of Z-bracket 26 and the terminal flat end 20 of U bend 19 on thesupporting stand bracket, after which a plurality of securing members such as the pins 35 may be driven through the molding leg 32 and the

components

28 and 24 so as to form an assembly.

Although I have described and illustrated the preferred embodiment of my invention, it will be understood that various changes may be made in the details thereof without departing from the scope of my appended claims.

I claim:

1. A rectangular supporting stand including a pair or opposed parallel track means for support and interengagement with a slidable shelf, said track means each comprising a flange secured to the opposed sides of the stand, said flange including a leg normal thereto projecting inwardly of said stand having a spaced upwardly returnbent U-terminus opening above said flange, a slidable tray on said track formed of sheet metal edgewise return-bent to form U-shaped flanges at its front and side edges, Z- shaped brackets having one flat end secured to the underface of said tray at the side and forward edges thereof and the other in spaced plane parallel relationship to the return-bent edges of the tray and terminating thereat downwardly and normally in a U-bend for slidable reception in the U-bend on said track, and a molding overlying the forward and side edges of the tray including the adjacent outer face of the U-bend on the Z bracket, including a longitudinally extending medial arm disposed between the free face of the Z-bracket and return-bent terminus edges of the tray.
