Abstract

A height adjustable workstation comprising a frame, a console supported by and movable up and down with the respect to the frame, and a keyboard tray supported by the console and pivotable with respect thereto when the console is moved down.

Claims

1. A height adjustable workstation comprising:

a stationary frame comprising a pair of side members,

a console supported by said frame between said side members and movable up and down with respect to the frame between a deployed position and a stowed position; and

a keyboard tray pivotally connected to the console and pivotable with respect thereto between a substantially horizontal position and a stowed position;

wherein the keyboard tray is in the substantially horizontal position when the console is in the deployed position, and is pivoted upwardly to the stowed position when the console is in the stowed position.

2. The workstation of claim 1 in which the console includes a first monitor rack and a second monitor rack angled outwardly over the first monitor rack.

3. The workstation of claim 1 further including at least one spring mounted to the frame and secured to the console and biased to drive the console up.

4. The workstation of claim 3 in which said spring is a constant force spring.

5. The workstation of claim 1 in which the frame includes two spaced rails and the console includes bearings which ride on the rails.

6. The workstation of claim 1 further including a latch for releasably locking the console in the stowed position.

7. The workstation of claim 1 further including an adjustable friction hinge assembly between the keyboard tray and the console.

8. The workstation of claim 7 in which the adjustable friction hinge assembly includes a first ear coupled to one side of the console, a first bracket coupled to one side of the tray, and a handle with a shaft extending through the first ear and into the first bracket.

9. The workstation of claim 8 in which the adjustable friction hinge assembly further includes a second ear coupled to an opposite side of the console, a second bracket coupled to an opposite side of the tray, a set of belleville washers, and a fastener extending through the belleville washers and the second ear and into the second bracket.

10. A height adjustable workstation comprising:

a stationary frame comprising a pair of side members, said frame including spaced rails;

a console supported by said frame between said side members, and including friction bearings which ride on the rails for moving the console up into a deployed position and down to a stowed position with respect to the frame;

a keyboard tray supported by the console and pivotable with respect thereto/between a substantially horizontal position and a stowed position;

wherein the keyboard tray is in the substantially horizontal position when the console is in the deployed position, and is pivoted upwardly to the stowed position when the console is in the stowed position; and

spring means for biasing the console into the deployed position.

11. The workstation of claim 10 in which the console, when fitted with one or more monitors, has a weight and the biasing force of the spring means is approximately equal to the weight and the friction force of the friction bearings.

12. The workstation of claim 11 in which the spring means includes a pair of constant force springs mounted to the frame and secured to the console.

13. The workstation of claim 10 further including an adjustable friction hinge assembly between the keyboard tray and the console.

14. The workstation of claim 13 in which the adjustable friction hinge assembly includes a first ear coupled to one side of the console, a first bracket coupled to one side of the tray, and a handle with a shaft extending through the first ear and into the first bracket.

15. The workstation of claim 14 in which the adjustable friction hinge assembly further includes a second ear coupled to an opposite side of the console, a second bracket coupled to an opposite side of the tray, a set of belleville washers, and a fastener extending through the belleville washers and the first ear and into the second bracket.
