Abstract

A doorstop that includes a retainer piece disposed on one of a door and a door support, the retainer piece including a plastic housing with a main opening and a guide opening arranged perpendicular to the main opening and parallel to a pivot axis of the door. The doorstop also includes a door retaining rod articulated on the other of the door and the door support. The door retaining rod passes through the main opening of the retainer piece housing and includes a brake ramp and a catch depression on a side of the door retaining rod. The doorstop also includes a catch device configured to determine specific door opening positions. The catch device includes a brake body and a spring. The catch device connects the retainer piece and the door retaining rod to each other in a moveable manner. The brake body includes a hollow cylinder having a semi-spherical closed end and an open end and is slidingly disposed in the guide opening of the retainer piece. The open end accommodates the spring so that the closed end is pre-tensioned by the spring relative to the brake ramp and catch depression and is guided in the guide opening free of tilt.
