ABSTRACT:
A sliding door employing a runner wheel assembly of the invention typically comprises a frame of hollow extruded frame elements. The hollow section of the bottom frame element is provided with two such wheel assemblies, one at each end, supporting the door for sliding movement, each assembly comprising a wheel retainer member and a wheel carrier or support member releasably secured to the retainer member. In normal use the wheel carried by the wheel support member projects through an opening of the bottom frame element to cooperate with a track. When the door is lifted from the track the wheel support member can be pivoted relative to the retainer member to a position from which it can be removed and replaced through the opening. The wheel support consists of a unitary member providing a non-circular bearing part which is inserted into a keyhole shaped aperture in the wheel retainer while the support is in one orientation, the support thereafter being rotated to another orientation for retention in the wheel retainer.
