An adjustable desk includes four extendable legs and an open-sided adjustable frame. The open-sided adjustable frame provides an open space between two of the extendable legs such that the open-sided adjustable frame is suitable for supporting a U-shaped desktop.
Claims24
An adjustable desk comprising:
- a first extendable leg including a first outer housing, a first inner housing, and a first actuation mechanism to selectively extend and retract the first inner housing relative to the first outer housing;
- a second extendable leg including a second outer housing, a second inner housing, and a second actuation mechanism to selectively extend and retract the second inner housing relative to the second outer housing;
- a third extendable leg including a third outer housing, a third inner housing, and a third actuation mechanism to selectively extend and retract the third inner housing relative to the third outer housing;
- a fourth extendable leg including a fourth outer housing, a fourth inner housing, and a fourth actuation mechanism to selectively extend and retract the fourth inner housing relative to the fourth outer housing;
- a motor configured to drive the first actuation mechanism to selectively extend and retract the first inner housing relative to the first outer housing;
- and
- a linkage coupling the motor to the second actuation mechanism such that the motor is configured to drive the second actuation mechanism in unison with the first actuation mechanism,
- wherein the linkage includes a telescopic drive shaft,
- wherein the telescopic drive shaft includes an outer tube with a central lumen, an inner rod within the central lumen and a fitting configured to selectively fix a position of the inner rod within the central lumen relative to the outer tube;
- and
- an open-sided adjustable frame including:
- a first crossbar extending between the first extendable leg and the second extendable leg;
- a second crossbar extending between the second extendable leg and the third extendable leg;
- a third crossbar extending between the third extendable leg and the fourth extendable leg;
- and
- a plurality of desktop mounts configured to facilitate securing a desktop to the open-sided adjustable frame,
- wherein the open-sided adjustable frame provides an open space between the first extendable leg and the fourth extendable leg.
