Adjustable armchair tray

Abstract

A multi-functional adjustable tray that mounts on the arm of a chair to provide a comfortably accessible work surface to support a computer mouse and other IO devices.

1 . An adjustable tray configured for connection to chair arm having a top surface and a width dimension, said adjustable tray comprising:
 an armchair stop fastened to said chair arm;   a platform defining a securing hole, said platform comprising an arm defining the securing hole and having a first rotatable joint, wherein the rotatable joint allows the generally planar surface to be rotated around a first axis; and   a movable fastener having body and a head, the body passing through the securing hole into the armchair stop, wherein the platform is rotatably connected to the armchair stop by the movable fastener, and wherein the platform is movable from an approximately horizontal plane to an approximately vertical plane.   
   
   
       2 . The adjustable tray of  claim 1 , wherein the arm further comprises a second rotatable joint, wherein the second rotatable joint allows the generally planar surface to be rotated around a second axis. 
   
   
       3 . An adjustable tray configured for connection to chair arm having a top surface and a width dimension, said adjustable tray comprising:
 an armchair stop;   a platform;   a first arm attached to the platform;   a second arm defining a securing hole;   a joint rotatably connecting the first arm and the second arm, wherein the platform may be rotated by rotating the first arm relative to the second arm; and   a fastener having a body and a head, the body passing through the securing hole into the armchair stop, wherein the second arm is rotatably connected to the armchair stop by the movable fastener.   
   
   
       4 . The adjustable tray of  claim 3 , wherein the armchair stop further comprises:
 a generally horizontal surface defining a first slot, the first slot adapted to retain the head of the movable fastener and to allow the body of the movable fastener to pass therethrough; and   a generally vertical surface defining a second slot, the second slot connected to the first slot and adapted to retain the head of the movable fastener and to allow the body of the movable fastener to pass therethrough;   wherein the movable fastener passes from the first slot to the second slot and vice-versa, allowing the platform to be positioned in an approximately horizontal plane and an approximately vertical plane.   
   
   
       5 . The adjustable tray of  claim 4 , wherein the vertical surface further defines:
 a third slot in the vertical surface, the third slot connected to the second slot and adapted to allow the body of the movable fastener to pass therethrough and adapted to retain the head of the movable fastener; and   a hole connected to the third slot and adapted to allow the head of the movable fastener to pass therethrough;   whereby the platform may be released from the armchair stop by passing the movable fastener through the third slot and passing the head through the enlarged region.   
   
   
       6 . The adjustable tray of  claim 3 , further comprising:
 an elongated guide adjustably connected to the armchair stop, wherein the elongated guide supports the armchair stop, the elongated guide is adjustable to fit the adjustable tray to the width dimension of the chair arm, and the elongated guide has a first end and a second end; and   a compression element circumvolving the chair arm and the elongated guide to secure the elongated guide to the chair arm.   
   
   
       7 . The adjustable tray of  claim 6 , wherein the armchair stop further defines a hole adapted to receive the first end of the elongated guide, and wherein the first end of the elongated guide is slideable within the hole to adjust the adjustable tray to fit the width dimension of the chair arm. 
   
   
       8 . The adjustable tray of  claim 6 , wherein the elongated guide further defines at least one slit; wherein the compression element passes through the slit to secure the elongated guide to the chair arm. 
   
   
       9 . The adjustable tray of  claim 6 , wherein the elongated guide is shaped in an S-curve to maintain the generally planar working surface approximately level with the top of the chair arm. 
   
   
       10 . The adjustable tray of  claim 6 , wherein the elongated guide further comprises a tab connected to the second end, wherein the tab is adapted to keep the compression element between the first end and the second end. 
   
   
       11 . The adjustable tray of  claim 6 , wherein the compression element is a strap. 
   
   
       12 . The adjustable tray of  claim 3 , wherein the armchair stop is rigidly affixed to the chair arm. 
   
   
       13 . The adjustable tray of  claim 3 , further comprising a retainer affixed to the platform to retain objects on the platform. 
   
   
       14 . The adjustable tray of  claim 3 , further comprising a cushioning material disposed on the platform, on the elongated guide, and on the armchair stop. 
   
   
       15 . The armchair tray of  claim 3 , wherein the platform is rotatably attached to the first arm. 
   
   
       16 . The armchair tray of  claim 3 , wherein the platform is adapted to accommodate a mouse. 
   
   
       17 . The adjustable tray of  claim 3 , wherein the platform further comprises an IO device. 
   
   
       18 . The adjustable tray of  claim 17 , wherein said IO device comprises a keyboard. 
   
   
       19 . The adjustable tray of  claim 3 , further comprising an elongated guide connected to the armchair stop, wherein the elongated guide supports the armchair stop, wherein the chair arm defines a first cavity adapted to movably accept the elongated guide, and whereby the position of the armchair stop relative to the chair arm may be adjusted by moving the elongated guide within the first cavity. 
   
   
       20 . The adjustable tray of  claim 19 , wherein the chair arm further defines a second cavity adapted to receive the armchair stop.
