Powered height adjustable desktop
First Claim
1. A height adjustable desktop, comprising:
- a base having a fixed peripheral wall extending upwardly from the base to define a cavity;
a cover defining a horizontal work surface for the desktop; and
a lift mechanism supporting the cover relative to the base, wherein the lift mechanism comprises;
a linkage comprising at least one pair of lift arms pivotably connecting each side of the base to a respective side of the cover;
a powered linear actuator attached to the base and operatively connected to the linkage,a connecting rod connected between a lift arm of each pair of lift arms; and
a lever directly or indirectly coupling the linear actuator to the connecting rod,wherein motion of the linear actuator causes rotation of the connecting rod, and rotation of the connecting rod directly rotates the lift arms,wherein the actuator is configured to selectively activate the linkage to rotate the lift arms from a relatively horizontal position to at least one substantially fixed upright position, thereby raising the work surface from a sitting height to a standing height, andwherein the cover rests upon the peripheral wall at the sitting height to fully enclose the cavity, and the cover is spaced above and offset forward of the base at the standing height,wherein each pair of lift arms includes a front lift arm and a rear lift arm, wherein the front lift arm and the rear lift arm each rotate in the same direction as the cover is raised and lowered.

Abstract
A powered height adjustable desktop having a base with a fixed peripheral wall defining a cavity and a cover defining a horizontal work surface. A lift mechanism supports the cover relative to the base. The lift mechanism includes a linkage with at least one pair of lift arms pivotably connecting each side of the base to a respective side of the cover and a powered actuator attached to the base and operatively connected to the linkage. The actuator selectively activates the linkage to rotate the lift arms from a relatively horizontal position to at least one substantially fixed upright position, thereby raising the work surface from a sitting height to a standing height. At the sitting height, the cover rests upon the peripheral wall to fully enclose the cavity. At the standing height, the cover is spaced above and offset forward of the base.

8. A support, comprising:
-
a base for placement upon an existing desk or table; a cover defining a horizontal work surface; and a lift mechanism supporting the cover relative to the base, wherein the lift mechanism comprises; a linkage comprising at least one pair of lift arms pivotably connecting each side of the base to a corresponding side of the cover; a powered linear actuator attached to the base and operatively connected to the linkage; a connecting rod capable of rotation along with at least one of the lift arms; and a lever directly or indirectly converting linear motion of the linear actuator to a torque rotating the connecting rod, and rotation of the connecting rod directly rotates the lift arms, wherein the linear actuator is configured to selectively activate the linkage to rotate the lift arms from a relatively horizontal position to at least one substantially fixed upright position, thereby raising the work surface from a sitting height to a standing height, and wherein the cover is spaced above and offset forward of the base at the standing height. - View Dependent Claims (9, 10, 11, 12, 13)

14. A device, comprising:
-
a cover defining a horizontal work surface; and a lift mechanism supporting the cover, wherein the lift mechanism comprises; a linkage comprising at least one pair of lift arms pivotably connected to each side of the cover; a powered linear actuator operatively connected to the linkage; a connecting rod connected between a lift arm of each pair of lift arms; and a lever directly or indirectly coupling the linear actuator to the connecting rod, wherein motion of the linear actuator causes rotation of the connecting rod, and rotation of the connecting rod directly rotates the lift arms, thereby raising the cover from the sitting height to the standing height. - View Dependent Claims (15)
