Abstract: A door stop for hollow walls having two drywall surfaces. The door stop comprises a cylindrical housing having an outwardly turned flange serving as a trim plate engaging the drywall surface exposed to the door knob of a swinging door. The flange is located at the exposed end of the housing. A piston occupies and is entrapped within a chamber formed in the housing. The piston is exposed to the door knob and presents surface roughly flush with the outer surface of the wall. The piston receives impacts when the door is swung so that the door knob strikes the wall. A spring inside the housing decelerates the piston responsive to the door being swung until contact with the wall ensues, and subsequently returns the piston to its original position. The chamber of the housing communicates to the exterior by a small orifice, so that piston movement is pneumatically dampened. A brace formed at the rear of the housing contacts the other drywall surface of the wall, such that impact forces are distributed over both drywall surfaces of the wall. The brace, which in alternative embodiments is selectively C-shaped or cruciform, is friction fit the rear wall of the housing.

Abstract translation: 一个具有两个干墙面的中空墙的门挡。 门挡板包括一个圆柱形外壳，其具有向外转动的凸缘，用作装饰板，该装饰板与暴露于摆动门的门把手的干墙表面接合。 凸缘位于外壳的暴露端。 活塞占据并被夹在形成在壳体中的室内。 活塞暴露于门把手，并将表面与墙壁的外表面大致齐平。 当门被摆动时，活塞接收撞击，使门把手撞到墙壁上。 壳体内部的弹簧响应于摆动的门而减速活塞，直到与壁接触，并随后将活塞返回到其初始位置。 壳体的腔室通过小孔与外部连通，使得活塞运动被气动阻尼。 形成在壳体后部的支架接触壁的另一个干壁表面，使得冲击力分布在壁的两个干墙表面上。 在替代实施例中，支架是选择性地C形或十字形的，与壳体的后壁摩擦配合。
