Abstract
An adjustable roller assembly for supporting and leveling an appliance including a rail secured to the appliance and having a keyhole opening with a horizontal stationary base frame secured to the rail. A bracket having a bottom end is pivotally secured to the base frame and the top end of the bracket has a threaded nut spaced from the keyhole opening in the rail. A roller is rotatably secured to the bottom end of the bracket and is movable up and down relative to the stationary base frame in response to pivotal movement of the bracket. A horizontally disposed bolt having a head portion, a shank portion, a threaded portion, and an unthreaded terminal end portion is provided with the shank portion passing through the keyhole opening in the rail. The head portion is located on one side of the rail, and the threaded portion on the opposite side of the rail and threadingly engages the nut. The shank portion has a stop projecting to prevent withdrawal of the shank portion through the keyhole opening in the rail and the stop projection and unthreaded terminal end portion are spaced from each other a distance greater than the distance of the nut from the keyhole opening in the rail to prevent withdrawal of the bolt from the threaded nut.
