Serving tray construction with adjustable clamp means

Claim 2

A serving tray adapted to be detachably clamped to a supporting structure comprising: a. a tray body having top and bottom sides; b. a single anchor rod fixed to the bottom side of said tray body and extending longitudinally thereunder along a median plane; c. anchor brackets slidably disposed on said single anchor rod, each said anchor bracket including end walls constituting a pair of spaced bearing lugs spaced apart on opposite sides of said anchor; and d. clamp means pivotally supported on the spaced bearing lugs of each said anchor bracket and resiliently biased in a clamping direction.

Claim 3

The combination according to claim 1, in which said tray body is provided with a peripheral flange extending below the bottom side thereof at opposite ends of said anchor rod, said peripheral flanges extending below said anchor rod and limiting axial displacement of said anchor rod in relation to the tray.

Claim 4

The combination according to claim 1, in which saddle means are provided on the bottom side of said tray body, said anchor rod lies cradled within said saddle means, and keeper means are provided associated with said anchor rod and saddle means to lock said anchor rod in position below said tray body.

Claim 5

The combination according to claim 1, in which flange means are provided extending below the bottom side of said tray body at opposite ends of said tray, and said anchor rod is proportioned in length to fit snugly between said flange means.

Claim 6

The combination according to claim 1, in which each said anchor bracket includes a centrally disposed lug bored to slidably receive said anchor rod, and is provided with a plurality of lateral extensions slidably engaging said tray bottom to provide three point stability of said anchor bracket on the anchor rod and tray bottom.

Claim 7

The combination according to claim 1, in which said clamp means is pivotally mounted on said anchor bracket for selective manipulation from a position of disuse in which the clamp means lie resiliently pressed against the bottom side of said tray body in substantial parallelism thereto to a position of use substantially perpendicular to said tray bottom in which sAid clamp means are resiliently biased in a clamping direction.

Claim 8

The combination according to claim 1, in which said clamp means includes two pairs of mutually extending spaced and parallel arms adjacent opposite ends of the tray body, each pair of spaced arms being pivotally mounted on an associated anchor bracket, one of said pair of spaced arms being proportioned to nest within the other pair of spaced arms when said clamp means are in position of disuse.

Claim 9

A serving tray adapted to be detachably clamped to a supporting structure comprising: a. a tray body having top and bottom sides; b. an anchor rod fixed to the bottom side of said tray body and extending longitudinally thereunder along a median plane; c. anchor brackets slidably disposed on said anchor rod, each said anchor bracket including a pair of spaced bearing lugs on opposite ends of the anchor brackets; d. a pivot pin carried by said bearing lugs; e. a coil spring concentrically disposed about said pivot pin between said lugs and having one end thereof anchored to said anchor bracket and the other end thereof resiliently abutting said clamp means; and f. clamp means supported on each said anchor bracket and resiliently biased in a clamping direction.

Claim 10

A serving tray adapted to be detachably clamped to a supporting structure comprising: a. a tray body having top and bottom sides; b. an anchor rod fixed to the bottom side of said tray body and extending longitudinally thereunder along a median plane; c. anchor brackets slidably disposed on said anchor rod, each said anchor bracket including a pair of spaced bearing lugs on opposite ends of the anchor brackets; d. a pivot pin carried by said bearing lugs; e. a coil spring concentrically disposed about said pivot pin between said lugs and having one end thereof anchored to said anchor bracket and the other end thereof resiliently abutting said clamp means; and f. clamp means supported on each said anchor bracket and resiliently biased in a clamping direction.
