Abstract
A guide rail for guiding a pair of angled or horizontal guide wheels ( ) of a guide assembly. The guide rail comprises a rail base ( ), a rail head ( ), and a rail web ( ) interconnecting the rail base ( ) with the rail head ( ). The rail head ( ) 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 ( ) 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 ( ) are only movable vertically into and out of engagement with the guide in the zone while the pair of guide wheels ( ) 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 ( ).
