摘要 The device of this invention is a collapsible, tray holder having an upper tray cradle, universally adapted to hold a variety of different types of trays, an upright support, and a base. The cradle portion includes a rear stabilizer and a spring loaded front clasp designed to receive and hold trays of different sizes and shapes. The base and the cradle are connected to the upright with locking hinge connections forming, when assembled, a substantially C-shaped support. The tray cradle may be unlocked and folded at the hinge connections, parallel to the upright, with or without a tray therein. The base connection may also be unlocked for pivotal movement to collapse the holder to an I-shaped configuration for shipment or storage.
权利要求
1. A collapsible tray holder comprising; an upright support; parallel bridge members pivotally connected to the base of said upright support at opposite sides thereof, with said bridge members extending from said upright support; a first lateral crossleg connecting adjacent ends of said bridge members opposite said upright support; a second lateral crossleg attached to said upright support and disposed adjacent said bridge members at the pivotal connection, said second leg disposed to stop pivotal movement of said bridge members into said upright support when said bridge members extend perpendicularly from the base of said upright; tray holding means including at least one bed member pivotally connected at an end thereof at the upper end of said upright support; and opposed hook members carried by said bed, for releasably engaging opposite edges of the tray; releasable stop means connected to said upright support adjacent said bed member at the pivotal connection thereof, for stopping pivotal movement of said bed member into said upright support when said bed member extends perpendicularly from said upright support so that when said stop means and said second leg are disposed abutting said bed and bridge members, respectively, said members are adapted to extend outwardly from said upright support substantially perpendicular thereto in an erect position, and when said stop means and said second leg are not disposed abutting said members, said members are adapted to be pivoted to a collapsed position.
2. The tray holder of claim 1 wherein the tray holding means comprises: twin bed members pivotally connected to said upright support at an end opposite said base and extending outwardly from said support; biased hooking means slidably received in said bed members at the end thereof opposite said upright support for receiving an edge of a tray; and a tray stabilizer pivotally connected to said bed members at an end thereof and disposed adjacent said upright support, said stabilizer disposed to receive an edge of a tray opposite the edge received by said hooking means.
3. The tray holder of claim 2 wherein the stop means comprises a stop rotatably connected to said upright support adjacent the pivotal connection of said bed members, said stop selectively preventing pivotal movement of said bed members into said upright support when said bed members extend outwardly from said upright support.
4. A collapsible tray holder comprising: an upright support; a base pivotally connected to said support; a tray bed pivotally connected to said support; a rear tray stabilizer pivotally engaging the rear of said bed for receiving the rear edge of the tray; a plurality of mutually spaced hooks, the shanks of said hooks slidably received in said bed, said hooks opening upwardly to receive the front edge of a tray; bias means connecting the shanks of said hooks and said bed for normally urging said hooks into said bed; a handle interconnecting the hooking portion of said hooks for withdrawing said hooks from said bed.
