ABSTRACT:
A device for preventing door slamming including a housing that has a bore formed therein, a control element that slides in the bore, the control element having a bore formed therein, a plunger that slides in and out of the bore of the control element, the plunger being biased against a distal end of the bore of the control element by a biasing device, and a stopper element received in the plunger and extending into the control element, wherein a slamming force applied on the plunger dislodges the stopper element from the plunger so that the stopper element becomes lodged in the control element and the housing, thereby preventing the control element from sliding in the bore of the housing.
