Patent ID: 8639081

Claim:
A slide arrangement, comprising: a) first and second rails including first and second structures, respectively; b) an I-shaped center rail including: i) a center portion having a longitudinal dimension that extends between opposite ends of the center portion; ii) transverse portions located at the ends of the center portion, the transverse portions being oriented transverse to the longitudinal dimension of the center portion to define the I-shape of the center rail; iii) the I-shape of the center rail defining first and second longitudinal constructions extending from a first end to a second end of the center rail, each of the first and second longitudinal constructions being sized to receive only one of the first and second structures of the first and second rails, respectively, each of the first and second structures of the first and second rails, respectively, being configured to slidably engage the first and second constructions of the center rail; iv) the first longitudinal construction of the center rail including a first longitudinal groove extending from the first end of the center rail to the second end, and the second longitudinal construction including a second longitudinal groove extending from the first end of the center rail to the second end; and c) a spool configured to contact at least one of the first and second rails when the first rail slides relative to the second rail, the spool having an axis of rotation parallel to a longitudinal dimension of the center portion of the I-shaped center rail.
