Lock device and sliding door including lock device

Abstract

It is an object of the present invention to use a simple structure to successively performing all operations of unlocking or locking and an opening support mechanism by one operation handle. A lock device includes: an operation mechanism (20) mounted to a stile of a sliding door being a door end stile or a meeting stile and configured to be operated with the operation handle (20a); a lock configured to lock or unlock the sliding door by the operation mechanism (20); the opening support mechanism (60) configured to kick out the sliding door; and a link bar (50) configure to connect between the operation mechanism (20) and the opening support mechanism (60). The operation mechanism (20) includes a slider (40) that can move vertically in conjunction with turning of a handle shaft (22) of the operation handle (20a). The opening support mechanism (60) is arranged at the link bar (50) while being away from the slider (40) at a predetermined interval, the link bar (50) being connected to the slider (40) and transmitting a vertical motion of the slider (40).

Description

technical field [0001] The invention relates to a lock device applied to doors and windows and a sliding door with the lock device. Background technique [0002] In order to overcome the inertial force to open the doors and windows that are larger and heavier than usual doors and windows, especially sliding doors, which are in a locked state, a relatively large force is required. In this way, since it is a door or window (sliding door) that initially requires a large force to open, a lock device having an opening assist mechanism is used. As such a lock device with an opening assisting mechanism, "a hook lock with an opening assisting mechanism" described in Patent Document 1 is known, for example. [0003] Figure 11 It is a vertical cross-sectional view of a conventional hook lock with an opening assist mechanism described in Patent Document 1 viewed from the front of a sliding door. [0004] The hook lock with an auxiliary opening mechanism is installed in the housing 1...

AI Technical Summary

Problems solved by technology

[0006] However, in the above-mentioned conventional shackle lock with an auxiliary opening mechanism, the operating part (handle switch lock lever, etc.) for locking and unlocking is separated from the operating handle for operating the auxiliary opening mechanism.

In such a hook lock with an opening assist mechanism, although the operations for unlocking and opening the window can be performed continuously, the operations for closing and locking the window are independent, so the operation is troublesome.

In addition, the structure of the hook lock with an auxiliary opening mechanism is also relatively complicated

[0007] Since the operating mechanisms of the jumper and hook bolts are all accommodated in one housing, not only the structure of the housing becomes complicated, but also it is difficult to dispose the jumper at any position apart from the position of the operating handle, and it is also impossible to arrange multiple jumping pole

In addition, due to the constraints of the housing, it is difficult to increase the size of each component, and it is difficult to transmit a large torque from the operating rod.
