Abstract
Wheels for movement along a floor-mounted track at the bottom of a sliding door are shown supported within U-shaped members which are pivotally coupled to brackets secured to the lower edge of the door. The wheels are prevented from being dislodged from the track via retainer elements, each of which is a channel element having an elongated opening in its web and inturned flange terminations at the edges of its walls. An integral plate extends from one side of the channel and is pivotally mounted on the pin or stub shaft extending through the wheel and U-shaped member. The retainer element is significantly longer than the diameter of the wheel, and the flange terminations are snapped over the track and in interference relation with lips of the track. The wheel at its lower portion extends through the opening in the retainer element and rides on the track. When the door is tilted or rocked, the flange terminations remain interlocked with the lips of the track, thereby keeping the wheel on the track while permitting the U-shaped member to pivot on the wheel and the bracket to pivot on the U-shaped member in accommodating the relatively non-parallel relations of the door and track.
