Abstract: A supporting roller assembly for a sliding closure, such as a sliding screen door, movable along a track and having an edge channel opening toward said track. The roller assembly has a bracket positioned in the edge channel of the panel, an arm pivoted at one end on the bracket and mounting a track engaging roller at its other end, and a spring for urging the roller toward the track. The invention provides a novel adjustable limit stop for limiting movement of the roller arm away from the track. The described stop is a plunger slidable in the bracket and urged by a spring into contact with the roller arm and a lock screw accessible from the outside of the panel for adjustably securing the plunger in fixed position. The lock screw also serves to secure the roller assembly on the channel.

Abstract translation: 用于滑动闭合件的支撑辊组件，例如滑动筛门，可沿着轨道移动并具有朝向所述轨道的边缘通道开口。 辊组件具有定位在面板的边缘通道中的托架，臂的一端在支架上枢转并且在其另一端安装轨道接合辊以及用于将辊推向轨道的弹簧。 本发明提供了一种新颖的可调限位装置，用于限制滚子臂远离轨道的移动。 所描述的止挡件是可在支架中滑动并且由弹簧推动的柱塞与辊臂接触的柱塞和可从面板外部进入的锁定螺钉，用于可调节地将柱塞固定在固定位置。 锁定螺钉还用于将辊组件固定在通道上。

Abstract: A SUPPORTING ROLLER ASSEMBLY FOR A SLIDING PANEL, SUCH AS A SLIDING SCREEN DOOR, MOVABLE ALONG A TRACK AND HAVING AN EDGE SURFACE FACING THE TRACK. THE ROLLER ASSEMBLY INCLUDES A SPRING BIASED ROCKER ARM HAVING A ROUNDED SEATING EDGE SEATING AGAINST THE PANEL EDGE SURFACE, A TRACK ENGAGING ROLLER ON THE ARM ADJACENT ONE END OF ITS SEATING EDGE, AND ATTACHMENT MEANS PIVOTALLY SECURED TO THE ARM ADJACENT THE OTHER END OF THE SEATING EDGE FOR SECURING THE ARM TO THE PANEL AND ADJUSTING THE ARM TO SHIFT THE POINT OF CONTACT OF ITS SEATING EDGE WITH THE PANEL EDGE SURFACE IN A DIRECTION ALONG THE SEATING EDGE, THUS TO ADJUST THE ROLLER TOWARD AND AWAY FROM THE PANEL EDGE SURFACE.
