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.

Abstract translation: 在滑动门的底部沿着地板安装的轨道运动的轮子被示出为支撑在U形构件内，U形构件枢转地联接到固定到门的下边缘的托架。 通过保持器元件防止车轮从轨道上移走，每个保持器元件是在其腹板上具有细长开口的通道元件和在其壁的边缘处的内翻法兰端接件。 整体板从通道的一侧延伸并且枢转地安装在延伸穿过车轮和U形构件的销或短轴上。 保持器元件显着地长于车轮的直径，并且法兰终端被卡扣在轨道上并且与轨道的唇缘成干涉关系。 其下部的车轮延伸穿过保持器元件中的开口并且骑在轨道上。 当门被倾斜或摇动时，法兰端子保持与轨道的唇缘互锁，从而将车轮保持在轨道上，同时允许U形构件在车轮上枢转并且支架在U形构件上枢转 以适应门和轨道的相对不平行的关系。
