The first member is configured to form a clip structure, having a clip base extending to a bend portion and a clip arm extending back along the clip base from the bend portion wherein the clip arm is biased against the clip base. The first member further includes a sliding stopper which is formed by making a “ | 05-21-2015 |
20150308170 | Energy-Saving Magnetic Lock - An energy-saving magnetic lock comprising: a first lock module mounted to a part of a door such as a doorframe; and a second lock module, mounted to the other part of the door such as a door panel which can pivot about the doorframe, for interacting with the first lock module, wherein the first lock module comprises: an electromagnet ( | 10-29-2015 |
20150354251 | LOCKING UNIT AND G-SENSOR ASSEMBLY FOR VEHICLE TRAY USING THE SAME - Disclosed are a locking unit and a G-sensor assembly for a vehicle tray using the locking unit. The locking unit may include a case unit fixed to a first object and a magnetic assembly for selectively engaging with a second object which is disposed outside the case unit. The magnetic assembly may be movably disposed in the case unit. When a shock is generated, the magnetic assembly may move from inside the case unit to outside the case unit by a repulsive force generated between magnets having a same polarity, and consequently engage with the second object and restrict rotation of the second object. | 12-10-2015 |
20160002955 | GATE LATCH ASSEMBLY - A gate latch arranged to be mounted to either a gate or gate post and adapted to co-operate with a component mounted on the other of the gate or gate post to hold the gate closed, the gate latch comprising: a latch mechanism, and a housing containing at least a portion of the latch mechanism, the housing being configured to receive at least one latch accessory to modify the gate latch. | 01-07-2016 |
