The latch lock can be unlocked via an unlocking member interlocking with the handle.

[0005]

In the case of the former conventional technique described above, the latch cannot be unlocked even if the handle is pushed and pulled on the lower part where the handle is pivotally supported, which is not convenient.

In the latter case, the operation is smooth when the center portion of the handle is operated, but when the upper and lower portions are operated, the movement of the parallel link mechanism may not be smooth and may feel heavy. Also, when the upper or lower part is operated suddenly, it hardly operates.

The present invention has been made in view of such circumstances,
An object of the present invention is to provide a door lock handle device that can smoothly release a latch lock even when any part of the handle is operated.

[0008]

According to the present invention, means for solving the above-mentioned problems are constituted as follows. That is, a vertically long handle is provided on each of an inner seat mounted on the indoor side of the door and an outer seat mounted on the outdoor side, and an unlocking member for retracting the latch head or an operating member for allowing the retracting. An unlocking member for actuating the latch head is provided in each of the inner seat and the outer seat in conjunction with each of the handles, and the latch head is retracted or retracted by pushing one of the handles or pulling the other handle. In a door lock handle device that allows the door to be opened, the one unlocking member is rotatable in the inner seat, and the other unlocking member is rotatable in the outer seat. It is characterized by being pivoted to.

Since the handle is supported by connecting a projecting piece protruding inside the center of the handle to the rotating end of the unlocking member, the handle is reliably released even if any part of the handle is operated. The lock member can be linked, and the latch lock can be unlocked with good operability.
