Abstract
A fastening device for axially fastening a rotatably mounted threaded pin to a closing element, in particular a door, having a fastening element, which can be screwed onto the threaded pin, and having a backward-rotation prevention means for securing the screwed-on fastening element, wherein the backward-rotation prevention means has a sealing region for sealing the threaded pin with respect to the closing element. The disclosure also describes a closure actuator and a closing element incorporating the fastening device.
Claims16
A fastening device for axially fastening a rotatably mounted threaded pin having a polygonal cross section to a closing element, the fastening device comprising:
- a fastening element that can be screwed onto the threaded pin;
- and
- a back-rotation prevention seal for securing the screwed-on fastening element, wherein the back-rotation prevention seal has a polygonal cutout for receiving the threaded pin so that the back-rotation prevention seal can be nonrotatably coupled to the threaded pin, and wherein the back-rotation prevention seal has a sealing region that seals the threaded pin in relation to the closing element.
A closure actuator for actuating a closure element, the closure element having a threaded pin having a polygonal cross section and a fastening device for fastening the threaded pin to a closing element, wherein the fastening device comprises a fastening element that can be screwed onto the threaded pin;
- and a back-rotation prevention seal for securing the screwed-on fastening element;
- wherein the back-rotation prevention seal has a sealing region that seals the threaded pin in relation to the closing element, and wherein the back-rotation prevention seal has a polygonal cutout for receiving the threaded pin so that the back-rotation prevention seal can be nonrotatably coupled to the threaded pin.
A closing element, having an actuating element, a closure element, and a closure actuator, wherein the closure actuator is configured to actuate the closure element, the closure element having a threaded pin and a fastening device for fastening the threaded pin to the closing element, wherein the fastening device comprises a fastening element that can be screwed onto the threaded pin;
- and a back-rotation prevention seal for securing the screwed-on fastening element;
- wherein the back-rotation prevention seal has a sealing region that seals the threaded pin in relation to the closing element, wherein the threaded pin has a polygonal cross section, and wherein the back-rotation prevention seal has a polygonal cutout for receiving the threaded pin so that the back-rotation prevention seal can be nonrotatably coupled to the threaded pin.
