Abstract
Abstract A knock-down tray rack having a horizontal base member, a pair of bow-shaped support members, and a pair of unitary side panels incorporating upright sleeve members at opposite side edges thereof for receiving the upright leg members of the support members, and being provided with opposed vertically spaced ledges for supporting trays thereon. The leg members of the support members are adapted to be easily telescopingly fitted in the corresponding sleeve members of the side panels so that the bow-shaped support members span the side panels and so that the bottoms of the leg members are securely received within corresponding socket members in the base member. The base member may be further supported by casters having mounting extensions extending into the open bottom ends of the depending leg members of the bow-shaped support members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A tray rack comprising: (a) a base member having at least one pair of socket members therein, (b) first and second side panels, each side panel having at least one elongated upright sleeve member, (c) at least one bow-shaped support member including a pair of elongated parallel upright members having upper end portions, a transverse bridge member integrally connecting said upper end portions, and free lower end portions, (d) each of said upright members being adapted to be telescopingly received in a corresponding sleeve member so that said bridge member is above said side panels in an upright assembled position, (e) said upright members being longer than said corresponding sleeve members, (f) said free lower end portions being securely received in said corresponding socket members to rigidly support said support member and said side panels on said base member, in said assembled position, and (g) support means on said side panels for supporting vertically spaced trays above said base member and between said side panels.
Claim 2
Dependent Claim
165 words
A tray rack comprising: (a) a base member having at least one pair of socket members therein, (b) first and second side panels, each side panel having at least one elongated upright sleeve member, (c) at least one bow-shaped support member including a pair of elongated parallel upright members having upper end portions, a transverse bridge member integrally connecting said upper end portions, and free lower end portions, (d) each of said upright members being adapted to be telescopingly received in a corresponding sleeve member so that said bridge member is above said side panels in an upright assembled position, (e) said upright members being longer than said corresponding sleeve members, (f) said free lower end portions being securely received in said corresponding socket members to rigidly support said support member and said side panels on said base member, in said assembled position, and (g) support means on said side panels for supporting vertically spaced trays above said base member and between said side panels.
Claim 3
Dependent Claim
27 words
The invention according to claim 1 in which said bow-shaped support member is an inverted U-shaped tubular support member and said pair of upright members are straight.
Claim 4
Dependent Claim
154 words
The invention according to claim 1 in which each of said side panels is substantially planar having top and bottom edge portions and opposed side edge portions, each of said side panels having an elongated upright sleeve member adjacent each of said side edge portions, and further comprising two of said bow-shaped support members, and two pair of socket members in said base member, the leg members of one of said bow-shaped members being adapted to be received in the corresponding sleeve members adjacent the same side edge portions of both said side panels, and the upright leg members of the other bow-shaped support member being received in the corresponding sleeve members adjacent the opposite side edge portions of both said side panels, whereby said support members span both said side panels, the spacing of said socket members being such that each socket member receives a corresponding lower end portion of a leg member.
Claim 5
Dependent Claim
114 words
The invention according to claim 3 in which said base member has a front end portion and a rear end portion, a pair of transversely spaced front socket members in the front end portion of said base member and a pair of transversely spaced rear socket members in the rear end portion of said base member, one of said bow-shaped support members constituting a front support member and the other of said support members constituting a rear support member, the leg mcmbers of said front support member being received in said front socket members and the leg members of said rear support member being received in the rear socket members, in said assembled position.
Claim 6
Dependent Claim
97 words
The invention according to claim 4 in which each of said side panels is formed of planar sheet material, the side edge portions of each of said panels being turned to form corresponding upright sleeve members for receiving the upright leg members of said bow-shaped support members, said support means for supporting vertically spaced trays comprising vertically spaced horizontal ledges struck out inwardly from the sheet material of each of said corresponding side panels, the vertical spacing of the ledges of said first panel being equal to the vertical spacing of the ledges of said second panel.
Claim 7
Dependent Claim
74 words
The invention according to claim 5 in which each of said sleeve members formed along a side edge portion of a side panel is formed by turning the side edge portions of said sheet material to form an upright sleeve wall substantially surrounding and snugly and slideably engaging the corresponding leg member of a bow-shaped support member in assembled position, to prevent any horizontal movement of said support members relative to said side panels.
Claim 8
Dependent Claim
83 words
The invention according to claim 5 in which the free lower end portions of said corresponding leg members are hollow and open at the bottom thereof, each of said socket members comprising a vertical opening through said base member, a caster for each leg member, each caster comprising caster mounting means having an extension for insertion into the open bottom end of each of said leg members, and means permitting swivel motion of each caster about the vertical axis of said leg member.
Claim 9
Dependent Claim
29 words
The invention according to claim 7 in which each of said extensions on said casters is adapted to force-fit within the bottom opening in each of said leg members.
Claim 10
Dependent Claim
26 words
The invention according to claim 6 in which each of said side panels including said ledges and said sleeve members are formed from unitary sheet material.
