Abstract
A latching device, which includes a lock frame mechanism fitted to a door and a corresponding latching mechanism fitted to a door frame. The lock frame mechanism is fixed to the inner side of the door, and is provided with a long locking arm able to horizontally swing, and the latching mechanism is provided with an extensible latch. When the latching device forms an unlatched state, the latch retracts to the side of the latching mechanism side, thereby achieving the effectiveness of preventing people from getting caught on a latch button when passing in and out and further giving an integrated aesthetic appearance to the door assembly.
Claims16
A latching device, comprising a lock frame mechanism fitted to a door and a corresponding latching mechanism fitted to a door frame, wherein:
- the lock frame mechanism comprises a base and a locking arm, the base is fixed to the inner side of the door, and the locking arm is pivotal configured on the base and able to horizontally swing, moreover, a slide groove is defined within the locking arm, and a drive element is located on the base or close to a pin connected position of the locking arm;
- the latching mechanism comprises a base and an extension mechanism provided with a latch, the base is fixed to the door frame and is used to enable the extension mechanism to be fitted thereto, the extension mechanism functions in correspondence with the drive element;
- whereby the drive element at the side of the lock frame mechanism controls movement of the extension mechanism at the side of the latching mechanism, thereby enabling the latch to extend towards the lock frame mechanism and form a latched state, and control by or release from the control of the drive element is used to cause the latch on the extension mechanism to retract and form an unlatched state.
