Tray with armrest clamp
First Claim
1. An apparatus, comprising:
- a tray;
a pivot housing attached to said tray, comprising an arm hub rotatably coupled to said pivot housing;
an armrest clamp comprising;
a clamping ring;
a stationary clamp jaw; and
a traveling clamp jaw driven in linear displacement relative to said stationary clamp by rotation of said clamping ring; and
a support arm comprising;
an end cap at a first end of said support arm;
a latch extending outward from said end cap; and
a tray release pushbutton attached to said latch,wherein;
said latch holds said arm hub stationary against said end cap when said support arm is connected to said pivot housing;
depressing said tray release pushbutton disengages said latch from said arm hub; and
disengaging said latch from said arm hub disconnects said pivot housing from said support arm.

Abstract
A tray attached to a pivot housing, support arm, and armrest clamp may be easily and quickly detached and reattached to an armrest on a chair. The tray may rotate around an arm hub when a stationary lower index plate in the arm hub is displaced from an upper index plate in the index housing. The tray is restrained from rotation when the upper and lower index plates are in contact with one another. The tray may be disconnected from the support arm while the support arm remains clamped to an armrest. The armrest clamp includes a bevel gear driven in rotation by a clamping ring on the support arm. The bevel gear drives rack gear attached to a traveling clamp jaw. Rotating the clamping ring displaces the traveling clamp jaw relative to a stationary clamp jaw, enabling the armrest clamp to securely clamp to an armrest.
