Abstract
The present invention relates to sliding supports and particularly sliding supports having two elongate members of channel section which slide one within the other. The invention address the problem of using such sliding supports in an orientation where the channels of the elongate members open vertically rather than horizontally. The sliding support preferably includes a damping mechanism for resisting relative sliding movement of the elongate members. The sliding support also preferably includes a mechanism for defining one or more intermediate positions between extended and shortened positions of the sliding support.
Claims31
A sliding support comprising a first elongate slide member of channel section, a second elongate slide member slidable in the channel defined by the first slide member, and locating means positioned between the first and second slide members to locate and align the first and second slide members for sliding without contact therebetween, the channel section of the first slide member having a base, side walls extending from the base, and a retaining lip extending from each side wall partly across the channel section opening to define an elongate gap between the two lips, the gap between the two lips and the lateral dimension of the second, slide member being such that, in the absence of the locating means such that the second slide member contacts one channel side wall of the first slide member, the second slide member is retained in the first channel by the lip extending towards the channel side wall with which the second slide member is in contact.
