Abstract
An apparatus having a sliding leaf, a slide member, at least two rail wheels mounted on respective spindles, a mounting mechanism affixed to the slide member and extending in a direction perpendicular to a plane of the sliding leaf, and fixing lugs affixed to and extending outwardly from a lower edge of the slide member at respective ends of the slide member. The slide member is a casing having two sets of recesses. The recesses in each set of recesses increase in height from a center of the casing to a respective end of the casing. The recesses in each set extend from the lower edge of the casing towards an upper wall of casing. The spindles have ends received by respective recesses of the two sets of recesses. The recesses have a narrowing so as to lock onto a respective end of the spindles. The casing is secured in a slot formed in a lower edge of the sliding leaf. The mounting mechanism enables the casing to rock within the slot. The mounting mechanism is a boss interposed between a bottom of the slot and the upper wall of the casing. The fixing lugs are formed of a flexible and spring material. The fixing lugs are affixed to the lower edge of the sliding leaf.
