Sliding door wheel retainer.

摘要

A wheel retainer (20) prevents a wheel (22) of a sliding or bypass door from jumping off of the floor track (18) on which the wheel rolls. Means (27) are provided on the lower portion of the retainer (20) for slidably engaging a downwardly facing portion of the track (18) for inhibiting upward movement of the retainer (20) from the track (18). Preferably this is in the form of an L-shaped hook (27) having a base wider than the opening of a dovetail slot (19) in the track (18) and a neck narrower than the opening of the slot. The retainer (20) can then be installed only by pivoting the retainer (20) relative to the track (18) for inserting the hook (27). The retainer (20) also has means (23; 28) for engaging an upper portion of the wheel (22) to prevent it from being lifted from the track (18). The preferred embodiment is a D-shape with an arcuate portion (23) over the top of the wheel and barbs (28) that prevent the retainer (20) from accidentally being dislodged from the wheel (22).
