Dishwasher rack channel cap

Image Number 3 for United States Patent #5061020.

A front opening household dishwasher has an upper rack having wheels that roll inside a C-shaped support channel, which in turn is mounted on support rollers attached to the inside of the tub. Each end of the channel is closed off by end caps to prevent the rack wheels from escaping from the channel, and to limit sliding movement of the channel with respect to the support rollers. Each end cap is a unitary structure having a body portion abutting the end of the channel and extending above and below the upper and lower edges of the channel. An arm portion is integral with the body portion and is connected thereto by a hinge portion at one side, and the arm extends through a pair of aligned openings at the upper and lower walls of the channel to engage a flexible detent hook on the other side of the channel to allow the end cap to be easily assembled and disassembled from the channel.
