Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case in which handles provided on both sides of a door are pushed in the opening and closing direction of the door.
The present invention relates to a door handle device in which a latch is immersed and can be opened as it is even when pulled.

[0002]

2. Description of the Related Art In a general door handle device, when a handle (lever handle or knob) is operated to rotate, a latch bolt of a latch lock is immersed and the door can be opened. It requires time and effort to rotate the door and to rotate the door in the opening direction with the hand holding the rotated handle. In order to simplify this trouble, there is a push-pull type handle device that can open the door by one-touch operation by pushing the handle in the opening direction (pulling in the opening direction with the handle on the opposite side of the door) (actual fairness 2). -49327).

A push-pull type handle device has a structure in which one handle mechanism rotates in a direction in which the handle is pushed to drive the latch of the latch lock in a retracting direction, and the other handle mechanism has a handle in which The latch is rotated in the pulled direction to drive the latch in the immersion direction. Since the rotating directions of both handles are opposite, the structures of the push-side handle mechanism and the pull-side handle mechanism are different. Therefore, the push-side handle mechanism and the pull-side handle mechanism must be separately prepared, and there are problems such as an increase in the number of parts and an increase in parts management.

[0004]

In order to solve such a problem, the handle of the handle mechanism is changed by selecting and inserting pins into two holes provided therein.
The push-side and pull-side handle mechanisms must also be used. In order to change the handle mechanism, one handle mechanism must be disassembled, the pin insertion position must be changed, and reassembly must be performed. In addition, a long working time is required.

[0005] Since the latch lock case is generally rectangular in shape, the hole for latch lock embedding provided in the end face of the door is also formed into a square hole. However, since engraving a square hole is more difficult than engraving a round hole, it is desirable to make the latch lock case a circular cylinder.

[0006] Door handle devices include those in which an empty lock that cannot be locked because the latch only protrudes and retracts is provided, and those that have a lock mechanism. The lock mechanism must be easily assembled in the empty lock. No. Further, in a partition door provided between rooms, a door that can be opened and closed by pushing or pulling from either side of the door without limiting the opening direction may be required. The present invention provides a door handle device that can solve such problems.

[0007]

In order to achieve the above object, a door handle device of the present invention has a latch insertion hole opened in the front of a lock case, and a latch is inserted into the latch insertion hole so as to be able to protrude and retract. A latch lock is provided on the end surface of the door, an escutcheon having an attachment surface fixed to both surfaces of the door is provided with a concave portion which is opened on the opposite side of the above-mentioned mounting surface, and a through hole communicating with the above-mentioned latch insertion hole is provided in the concave portion.

A shaft is provided, and the lever core fixed to the handle is An elongated hole pivotally attached to the pivot and the second support shaft is loosely fitted in the lever core and a long groove in which the first support shaft is loosely fitted, and the first support shaft and the second support shaft are arranged in opposite directions. When the first support shaft and the second support shaft move in the biasing direction, the drive unit rotates in a direction in which the latch protrudes, and the first support shaft and the second support shaft. When one of the two support shafts is pushed in the direction opposite to the biasing direction, the drive unit rotates in a direction in which the latch is retracted.

The latch is inserted into the latch insertion hole formed in the inner surface of the circular cylindrical lock case, and can be inserted into the latch insertion hole so that the tip can be tilted. It can be constituted by a latch stopper which is inserted into the insertion hole so as to be able to advance and retreat, and which locks the reversing latch in an upright state when the distal end portion is engaged with the engaging portion.
