Variable height desk

Abstract

A desk having a desktop and a lever coupled to a lower surface of the desktop. The desk has leg coupled to the lower surface and including an inner leg telescopically moveable with respect to an outer leg. The desk has a pin extending through an aperture in the outer leg and coupled to the lever with a linkage system. The lever is configured to retract the pin into the inner leg or outer leg allowing the desktop to move between a first height and a second height.

1 . A desk, comprising:
 a desktop;   a lever coupled to a lower surface of the desktop;   a leg coupled to the lower surface and including an inner leg telescopically moveable with respect to an outer leg; and   a pin extending through an aperture in the outer leg and coupled to the lever with a linkage system,   wherein the lever is configured to retract the pin into the inner leg or outer leg allowing the desktop to move between a first height and a second height.   
     
     
         2 . The desk of  claim 1 , the linkage system comprising:
 a rod coupled to the lever;   a cable coupled at a first end to the rod and at a second end to the pin,   wherein pressing the lever rotates the rod to lift the cable and retract the pin.   
     
     
         3 . The desk of  claim 2 , wherein the cable is coupled at the second end to the pin via an actuating member and a cantilever bar. 
     
     
         4 . The desk of  claim 3 , wherein upward movement of the cable within the leg retracts the actuating member and pin into the leg, the retracting permitting movement between the first height and the second height. 
     
     
         5 . The desk of  claim 4 , wherein the actuating member retracts against the force of a biasing member. 
     
     
         6 . The desk of  claim 1 , wherein a biasing member biases the pin into the aperture. 
     
     
         7 . The desk of  claim 1 , further comprising a biasing member within the outer leg, the biasing member configured to bias the desktop to an upward position. 
     
     
         8 . The desk of  claim 1 , wherein the lever is coupled to a second linkage system coupled to a second pin in a second inner leg and a second outer leg, and wherein pressing the lever retracts the second pin. 
     
     
         9 . The desk of  claim 8 , further comprising a second lever coupled to a third linkage system coupled to a third pin in a third inner leg and a third outer leg, the second lever coupled to a fourth linkage system coupled to a fourth pin in a fourth inner leg and a fourth outer leg, and wherein pressing the second lever retracts the third pin and retracts the fourth pin. 
     
     
         10 . The desk of  claim 9 , wherein the lever and the second lever are configured to be pressed simultaneously to move the desktop between the first height and the second height. 
     
     
         11 . The desk of  claim 1 , further comprising an elastic member located in the leg, the elastic member adapted to bias the inner leg and outer leg away from one another. 
     
     
         12 . The desk of  claim 1 , further comprising a second lever coupled to a second linkage system, the second linkage system coupled to a second pin in a second inner leg and a second outer leg, wherein pressing the second lever retracts the second pin. 
     
     
         13 . The desk of  claim 12 , wherein the lever and the second lever are configured to be pressed simultaneously to move the desktop between the first height and the second height.
