Abstract:
1. A device for pulling a door panel or a window casement toward a frame, comprising: a traction device arranged in a rabbet of the door panel or the window casement or a rabbet of the frame; a retracting block arranged in the other of the rabbet of the frame or the rabbet of the door panel or window casement; the traction device and the retracting block being arranged such that the traction device engages the retracting block when the door panel or window casement mates with the frame; the retracting block having a stationary inclined retracting structure, the inclined retracting structure being angled with respect to a vertical axis; the traction device including a traction element linearly movable along the vertical axis and a spring disposed so as to load the traction element, wherein the traction element includes a traction bolt protruding from and fixed relative to the traction element so as to directly engage with the inclined retracting structure when the door panel or window casement mates with the frame, the traction device further having a release member for retaining and releasing the traction element to move along the vertical axis; wherein when the traction device engages the retracting block, the release member releases the traction element such that the traction bolt directly engages the inclined retracting structure and the spring urges the traction bolt to move along the inclined retracting structure, thereby pulling the door panel or window casement towards the frame.
