Lift mechanism systems and methods
First Claim
1. A lift mechanism, comprising:
- a fixed component having proximal and distal ends;
a movable component disposed in sliding or rolling engagement with the fixed component;
a wheel pivotally supported by one of the components about a pivot axis, the wheel comprising a pulley member and a cam member with an eccentric shape;
a first cable connecting the cam member of the wheel to a spring for biasing the wheel to rotate in a first direction;
a spring plate disposed between one or more coils of the spring, wherein the spring plate is coupled to one of the first cable, the movable component, or the fixed component; and
a second cable connecting the pulley member to one of the components so that the wheel rotates when the movable component is moved relative to the fixed component.

Abstract
The invention includes a display positioning assembly comprising a support, a display supported by the support, and a balance mechanism carried by the display and operatively connected to the support. The invention also includes an article for selectively exposing a display comprising a generally planar support surface having a first side and a second side opposite the first side. A balance mechanism operatively connected to a display may be positionable between a storage position proximate the first side of the generally planar support surface and an exposed position proximate the second side of the generally planar support surface. The invention also includes an assembly for arresting the free fall of an object. The assembly may comprise an outer slide in sliding or rolling engagement with an inner slide, and a brake comprising at least one pivot member may be coupled to the inner slide.

13. An apparatus, comprising:
-
a support surface; one or more legs configured to support the support surface; and a lift mechanism positioned under the support surface, including; a fixed component having proximal and distal ends, a movable component disposed in sliding or rolling engagement with the fixed component, a wheel pivotally supported by one of the components about a pivot axis, the wheel comprising a pulley member and a cam member with an eccentric shape, a first cable connecting the cam member of the wheel to a spring for biasing the wheel to rotate in a first direction, a spring plate disposed between one or more coils of the spring, wherein the spring plate is coupled to one of the first cable, the movable component, or the fixed component, and a second cable connecting the pulley member to one of the components so that the wheel rotates when the movable component is moved relative to the fixed component. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A lift mechanism, comprising:
-
a fixed component having proximal and distal ends; a movable component disposed in sliding or rolling engagement with the fixed component; a wheel pivotally supported by one of the components about a pivot axis, the wheel comprising a pulley member and a cam member with an eccentric shape; a first cable connecting the cam member of the wheel to a spring for biasing the wheel to rotate in a first direction; a spring plate disposed between one or more coils of the spring, wherein the spring plate is coupled to one of the first cable, the movable component, or the fixed component; and a second cable connecting the pulley member to one of the components so that the wheel rotates when the movable component is moved relative to the fixed component, wherein at least the first cable does not include metal, but rather comprises a tensile polymer. - View Dependent Claims (26)
