Abstract

An electric assisted height adjustable workstation featuring an integrated user interface for height adjustment and power control resulting in zero standby power consumption is described. Power is connected to the workstation via a physical movement of the integrated user interface causing an integrated connector to complete a circuit. Power is disconnected between the power source and the workstation via physical retraction of the integrated UI or an automatic retraction if the user interface remains inactive for a period of time.

First claim

The claimed invention is:

1. A height adjustable workstation, comprising:
a worksurface;
a support leg coupled to the worksurface;
an electric motor coupled to the support leg, wherein the electric motor is configured to translate a movable portion of the support leg relative to a stationary portion of the support leg;
a power source;
a mechanically actuated connector coupled to the worksurface and connected to the power source, the mechanically actuated connector comprising:
a first power connector connected to the power source;
a second power connector spaced apart from the first power connector; and
a connector interlock operational between an engaged position and a disengaged position, in the engaged position, the connector interlock connects the first power connector and the second power connector, and in the disengaged position, the connector interlock disconnects the first power connector and the second power connector; and

a controller connected to the second power connector and configured to be connected to the power source via the mechanically actuated connector, the controller comprising:
a height adjustment controller connected to the electric motor;

wherein:
in the engaged position, the connector interlock connects the controller to the power source to power the height adjustment controller such that the height adjustment controller controls the electric motor to drive the movable portion to change a height of the worksurface; and
in the disengaged position, the connector interlock disconnects the controller and the power source.

2. The height adjustable workstation of claim 1 , wherein the support leg is a fixed height riser.

3. The height adjustable workstation of claim 1 , wherein the support leg is a telescoping riser.

4. The height adjustable workstation of claim 1 , wherein the stationary portion is supported by a structure, wherein the movable portion is slidingly engaged with the stationary portion.

5. The height adjustable workstation of claim 1 , further comprising:
a base, wherein the stationary portion is supported by the base, and wherein the movable portion is slidingly engaged with the stationary portion.

6. The height adjustable workstation of claim 5 , wherein the electric motor is coupled between the stationary portion and the movable portion, wherein the electric motor is configured to drive the movable portion to change a height of the worksurface.

7. The height adjustable workstation of claim 1 , wherein the controller further comprises:
a timer controller, including a timer, the timer controller configured to cause the connector interlock to disengage when the timer reaches a limit.

8. The height adjustable workstation of claim 1 , wherein the support leg is a linkage assembly coupled between a base and the worksurface.

9. The height adjustable workstation of claim 8 , wherein the stationary portion is a worksurface, wherein the movable portion is a moving bracket, and wherein the linkage assembly further comprises:
a parallel linkage assembly having a proximal end and a distal end;
a transverse linkage having a first end and a second end; and
the moving bracket slidingly engaged with the worksurface,
wherein the parallel linkage assembly is rotatably coupled with the base at the proximal end, and rotatably coupled with the moving bracket at the distal end, and
wherein the transverse linkage is rotatably coupled to the worksurface at the first end of the transverse linkage, and rotatably coupled with the parallel linkage assembly at the second end of the transverse linkage.

10. The height adjustable workstation of claim 9 , further comprising an electric motor connected to the worksurface and the moving bracket.

11. The height adjustable workstation of claim 1 , wherein the first power connector of the mechanically actuated connector is configured to move in a first direction to engage with the second power connector of the mechanically actuated connector, and is further configured to move in a second direction opposite the first direction to disconnect from the second power connector of the mechanically actuated connector.

12. The height adjustable workstation of claim 1 , wherein the first power connector of the mechanically actuated connector is configured to rotate in a first direction to engage with the second power connector of the mechanically actuated connector, and further configured to rotate in a second direction opposite the first direction to disconnect from the second power connector of the mechanically actuated connector.

13. The height adjustable workstation of claim 1 , wherein the mechanically actuated connector further includes a user interface.

14. The height adjustable workstation of claim 13 , wherein the user interface is exposed when the mechanically actuated connector is in the engaged position and hidden when the mechanically actuated connector is in the disengaged position.

15. A height adjustable platform, comprising:
a support bracket;
a riser coupled to the support bracket;
an electric motor coupled to the riser, wherein the electric motor is configured to drive a second member of the riser slidingly engaged with a first member of the riser to change a height of the support bracket;
a power source;
a mechanically actuated connector connected to the power source, the mechanically actuated connector comprising:
a first power connector connected to the power source;
a second power connector spaced apart from the first power connector; and
a connector interlock operational between an engaged position and a disengaged position, in the engaged position the connector interlock connects the first power connector and the second power connector, and in the disengaged position, the connector interlock disconnects the first power connector and the second power connector; and

a controller connected to the second power connector and configured to be connected to the power source via the mechanically actuated connector, the controller comprising:
a height adjustment controller connected to the electric motor; and
a timer controller including a timer;

wherein:
in the engaged position, the connector interlock connects the controller to the power source to power the height adjustment controller such that the height adjustment controller controls the electric motor to drive the second member to change a height of the support bracket;
in the disengaged position, the connector interlock disconnects the controller and the power source; and
the timer controller is configured to move the connector interlock into the disengaged position when the timer reached a limit.

16. A height adjustable support bracket-, comprising:
a support bracket;
a base;
a telescoping riser coupled to the support bracket;
an electric motor coupled to a first member and a second member of the telescoping riser, wherein the electric motor is configured to drive the second member to change a height of the support bracket;
a power source;
a mechanically actuated connector connected to the power source, the mechanically actuated connector comprising:
a first power connector connected to the power source;
a second power connector spaced apart from the first power connector; and
a connector interlock operational between an engaged position and a disengaged position, in the engaged position the connector interlock connects the first power connector and the second power connector, and in the disengaged position, the connector interlock disconnects the first power connector and the second power connector; and

a controller
