Abstract: A friction applying assembly for a panel movable from a first position to a second position which includes a mounting plate rigidly secured to the panel with the plate having a non-circular aperture. There is a hinge support arm having at one end a non-circular aperture and a bolt arm having a head at one end, which bolt arm is inserted into the non-circular aperture of the hinge support arm to prevent relative movement between the bolt arm and hinge support arm. The bolt arm is elongated having a large diameter section adjacent the head and a smaller diameter section at the opposite end and a tapered conically shaped intermediate section between the large diameter section and small diameter section. An elongated bushing body having one end inserted into the non-circular aperture of the mounting plate is secured thereto to prevent relative movement between the bushing and mounting plate. The bushing has an internal tapered conically shaped cavity complementary to and in frictional engagement with the intermediate section of the bolt arm. A compression spring having one end seated against the bushing and the opposite end retained by fastener means on the smaller diameter section of the bolt arm urges the bushing into movable frictional engagement with the tapered conically shaped intermediate section of the bolt arm.

Abstract translation: 一种用于面板的摩擦施加组件，其可从第一位置移动到第二位置，所述摩擦施加组件包括刚性地固定到所述面板的安装板，所述板具有非圆形孔。 铰链支撑臂的一端具有非圆形孔和一端具有头部的螺栓臂，该螺栓臂插入铰链支撑臂的非圆形孔中，以防止螺栓臂之间的相对运动 和铰链支撑臂。 螺栓臂是细长的，其具有与头部相邻的大直径部分和相对端部的较小直径部分，以及在大直径部分和小直径部分之间的锥形锥形中间部分。 将一端插入安装板的非圆形孔中的细长衬套主体固定到其上以防止衬套和安装板之间的相对运动。 衬套具有与螺栓臂的中间部分互补并与之相互摩擦接合的内锥形锥形腔。 一个压缩弹簧，其一端靠在衬套上，而相对的端部通过紧固装置保持在螺栓臂的较小直径部分上，促使衬套与螺栓臂的锥形锥形中间部分形成可动的摩擦接合。
