InactiveUS20060000955A1Without risk of damage to the article or an inadvertent retraction thereofExtend evenlyOffice tablesStands/trestlesConstant-force springConstant force
An extension and retraction arrangement for retaining a supported article, such as a monitor, in relation to a trolley structure that is retained for axial extension and retraction in relation to an elongate support arrangement. A support arm, which can be unitary, articulated, pivoting, or non-pivoting, can be coupled to the trolley structure. The trolley structure can have a centrally disposed alcove disposed inboard of first and second rail members of the elongate support arrangement. A subsurface enclosure can retain the rail members, and first and second doors can selectively close an aperture in a framework coupled adjacent to an end of the subsurface enclosure. Constant force springs can assist travel of the trolley structure and an arcuate braking member or compressing spring can provide a braking effect to the trolley structure

Cable retractor

A cable retractor for use in a variety of applications includes a housing forming an internal chamber, and first and second drums within the chamber for winding of the cable. The first drum may include a stationary outer surface, and the second drum may be formed by a plurality of rollers mounted on a rotatable frame. The rollers may orbit about the first drum upon rotation of said frame, with each of the rollers also rotating about its own roller axis. The first and second drums may be sized to enable wrapping of the cable both side-by-side and in multiple layers about at least one of the first drum and the second drum. The cable retractor may include structure to urge the rollers to rotate with respect to the frame as the frame rotates. For example, a portion of the rollers may be frictionally engaged with a track, and capable of slipping with respect to the track to provide smooth extension and retraction of the cable even as multiple layers of cable are wound about the first and second drums.
