Patent number: 7516992Abstract: A latch structure is provided herein. The latch structure comprises a base, a plate, a rotating element, hooks, a magnetic element, springs, locating posts, a latch element, a pushing element, and screws. One side of the magnetic element is rotatable by the pin, and the other side is mounted with the spring and the locating post. When door is closed inwardly, the pushing element pushes the rotating element forwardly to push the magnetic element contacting with the latch element which are attracting due to the magnetic field. The hooks then engage with the connecting portions. When power is off, spring abuts the magnetic element to release the hook from the connecting portion. The benefit is that as long as the attract force of the magnetic field larger than the pressure of the spring, the hooks and the latch element are decided to engage or separate, increasing the load ability of the latch structure. It is therefore large load ability is acquired only required few attract force, decreasing costs.Type: GrantFiled: December 14, 2006Date of Patent: April 14, 2009Assignee: Door & Window Hardware Co.Inventor: Jung-Chang Peng
