Abstract
A guide rail for guiding a pair of angled or horizontal guide wheels (17,18) of a guide assembly. The guide rail comprises a rail base (2), a rail head (4), and a rail web (3) interconnecting the rail base (2) with the rail head (4). The rail head (4) has at least one zone facilitating engagement and disengagement of the guide wheels with the guide rail. The zone has a narrowed area in which the guide head (4) has a narrower transverse width dimension which is less than the larger transverse width dimension on opposite sides of the zone and less than a normal engagement spacing of the guide wheels from one another such that the pair of guide wheels (17,18) are only movable vertically into and out of engagement with the guide in the zone while the pair of guide wheels (17,18) are prevented from moving vertically into and out of engagement with the guide rail, relative to the guide rail, by the larger transverse width dimension of the guide head (4).
