Abstract: A runner wheel support for sliding doors, windows and the like consists of a support body which is a press fit in the respective frame, and which carries the support wheel or roller on an arm carried by a disengageable pivot. The wheel support arm has a cam member cooperating with a height adjustment screw and spring fingers on the support body to hold the wheel support in a stored position while the support body is fitted into a frame member, and thereafter to free the wheel support from this stored position and to hold it in an operative position. Preferably the support body is of L-shape and acts as a connector to join together mitre-cornered pieces of frame. Movement of the wheel support arm to a removal position disengages the cam member from the spring fingers, so that the arm can be disengaged from the pivot and removed. A spring is provided to urge the wheel support arm to the operative position, and the arm is provided with transversely-extending dimples that engage the bore side walls to centralize the wheel.

Abstract translation: 用于滑动门，窗等的滚轮支架由支撑体组成，该支撑体压配合在相应的框架中，并且将支撑轮或滚轮承载在由可脱离的枢轴所承载的臂上。 车轮支撑臂具有凸轮构件，凸轮构件与支撑体上的高度调节螺钉和弹簧指配合，以将支撑体保持在存储位置，同时将支撑体装配到框架构件中，然后从其中释放车轮支撑件 存储位置并将其保持在操作位置。 优选地，支撑体是L形并且用作连接器以将斜角的框架连接在一起。 车轮支撑臂移动到拆卸位置使凸轮构件与弹簧指状件脱离，使得臂可以从枢轴脱离并移除。 提供弹簧以将车轮支撑臂推动到操作位置，并且臂设置有横向延伸的凹坑，其接合孔侧壁以集中轮子。
