  • Patent number: 7293328
    Abstract: A device for closing a door, including a spring element, an attachment element for fixing the device to a door, and an actuation element. The actuation element and the attachment element are linked at opposite ends of the spring element in such a way that, when the door is opened, differential rotation of the actuation element and the attachment element cause the spring element to be stretched and the energy stored in the spring element causes the door to close automatically. The actuation element is embodied as a support element that can be placed against the door frame or the adjacent wall regions in a supporting manner, and the attachment element can be removably mounted on an edge of the door without the use of fasteners or adhesive.
