  • Publication number: 20070136991
    Abstract: The present invention relates to a buffer hinge. More particularly, the return spring is used to automatically open and close the door, and one end of the axis with a corresponding rotation is affixed with the buffer component with multiple convexes. The buffer component is positioned into the buffer container of the positioning component at one end of the positioning return spring. Moreover, the buffer container has multiple concaves for embedding the convexes of the buffer component. Therefore, when the angle for opening the door is larger, the return torque produced from the return spring has a greater increase. However, when the embedding number between the convexes and the concaves is relatively increased, the buffer resistance between the two is also larger. On the contrary, when the angle for closing the door is smaller, the return torque produced from the return spring has a smaller decrease.

  • Publication number: 20070136999
    Abstract: The present invention relates to a structure for connecting the hinge flap and the door. More particularly, the outer side of the hinge flap in the door structure has a baffle side, and the inner side of the hinge flap has multiple baffle panels. Further, the baffle side and battle panel can form a lean guide side for the door. Besides, the upper and the lower of the hinge use the baffle side or the baffle panel in any sides of the hinge flap to lean on the door. Instead, the door is embedded into the middle of the baffle side and the baffle panel. Furthermore, two axes in the upper and the lower of two hinges for pivoting can be accurately positioned in the same centerline of the axis. It does not cause the occurrence of any incline. Moreover, the door can swing smoothly because the door is affixed with the door socket. Furthermore, the hinge also can have a long working life.
