ABSTRACT:
An improved closing device for opening and closing a slidable drawer is presented. The device entails an elongate hollow cylindrical housing having an axial slot extending from one end over at least a part of the body and second axial slot being ‘L’ shaped where the leg of the L is adjacent and substantially parallel to first slot. A cylindrical member is slidable in the body with the projection extending from the member inserted into a second slot. The cylindrical piece with angled groove is able to receive a pin attached to the guide rail of the drawer so that when the draw is opened the pin pulls the cylindrical piece along the first slot towards the angled section. The cylindrical piece rotates and locks due to the extension on second slot. Furthermore, when the drawer is closed the pin on the guide rail, when pushed in, engages with the first slot that rotates the cylindrical piece thus releasing the extension and the spring pulls the drawer to a closed position.
