Title:
HINGE
Document Type and Number:
WIPO Patent Application WO/2016/033980
Kind Code:
A1
Abstract:
A hinge used for being installed on a door and window leaf and a door and window frame (7). The hinge comprises a gear and rack unit and an inclined draw bar (1). The gear and rack unit is installed on the door and window frame (7). A gear (5) is rotatably installed on the door and window frame (7). A rack is located on one side of the gear (5). The gear (5) is meshed with the rack. A gear installation portion (51) is arranged on one side of the gear (5). The two ends of the inclined draw bar (1) are installed on the door and window leaf and the door and window frame (7) respectively. The door and window leaf can be smoothly opened and closed on the door and window frame by means of the gear and rack unit on the premise that the number of hinge parts is reduced, and the gear and rack unit can form a force arm outside the gear installation portion. The weight of the door and window is partially borne by the gear installation portion, most of the gravity of the door and window can be counteracted by the force arm formed by the gear and rack unit, and therefore the weight of the door and window can be largely shared; in this manner, the problem that the existing hinge is unreasonably stressed and prone to damage is effectively solved.
