Addition inhibitor for doors. To prevent the loud slamming of doors already exist devices. various types in which automatically an object between the door leaf and door frame is clamped. Most of these known devices are forcible and consist predominantly of a non-simple mechanism that is more or less reliable and also defaces the doors. One of the known advantages. directions z. B. should fulfill said purpose as a free-swinging pendulum, but this does not happen properly because the axis of rotation of the pendulum is located at its upper end and consequently when closing the door, the pendulum from the centrifugal force quickly, but also swings back quickly. As a result, it usually gets into its vertical rest position before the door has reached its closed position and can be prevented from slamming.

This disadvantage is eliminated in the new invention in that the pendulum is formed by a rod whose axis of rotation i is close to its gravitational force, so that the torque of the pendulum is small. As a result, when quickly closing the door, the pendulum oscillates both slowly outwards and backwards, so that it between. Door leaf and door frame is clamped before the former has reached its closed position. In this way, therefore, the door is prevented from slamming and can only and only then be completely closed after the pendulum is released from its clamping position and returned to its vertical rest position. When the door closes slowly, the pendulum swings. Not at all and thus does not interfere with the closing of the door. This is the main difference with respect to the known positively acting devices.

In the drawing, an embodiment of the new Zuschlaghinderers is shown. Figs. 1 and 2 show the pendulum in front and side view and Fig. 3, 4 and 5 the attachment of the pendulum to a door.

The above the center of gravity c of the pendulum a. attached opening b serves to receive a wood screw or a nail d fastened to the edge of the door leaf t as an axis of rotation for the pendulum. In the swung out position, ie when the door closes quickly, the pendulum a strikes against the door frame r, thus preventing the door slamming.

To be easy or difficult to move. Doors to be able to adjust the oscillation speed of the pendulum to those are expediently for the pivot pin d a plurality of openings b, b1, b2 mounted in pendulum a.

The pendulum is suitably made wholly or partly of elastic material.
