But, on this plane handle device with lock, since handle is protruded from housing so that door is unlocked and opened, must insert the specified key in the rotor of lock device, then rotate rotor, be connected with rotor There is a disadvantage of troublesome operation when the door needs to be opened and closed many times in the usual business during the day because the latch slides backward due to the operating part of the lock.

Therefore, the object of the present invention is to provide a kind of push-button type planar handle device with a lock like this: in the usual business during the day, the handle can be easily made to protrude by one touch operation; Finally, the random opening of the door can be reliably prevented by regular locking.

Another object of the present invention is to provide a flat handle device with a lock which can simplify the overall structure and reduce the cost of manufacturing and assembling because the lock also functions as a button.

The button-type planar handle device with lock of the present invention, its main components include: a housing 2 fixed on the door 1; A stop plate (metal) 5 fixed on the lock shaft 6 connected to the handle 10; a latch 16 for locking the handle 10 in the sunken position; and a lock device 21 for driving the latch 16 to the unlocked position.

The above-mentioned locking shaft 6 is inserted into the shaft tube portion 4 of one end portion 3 of the housing 2 in such a manner that it can rotate but cannot move axially; on the rear end portion of the locking shaft 6, a stop The moving plate 5 ; the base end 8 of the handle 10 is pivotally connected to the front end of the locking shaft 6 by crossing the pivot 9 . Between the locking shaft 6 and the handle 10, there is arranged a spring 11 for driving the handle. The spring 11 for driving the handle is centered on the above-mentioned pivot 9 so that the handle 10 is rotationally urged toward the protruding direction. The latch 16 accommodated in the other end 12 of the housing 2 can slide forward and backward toward the front end 13 of the handle 10 . The stop receiving portion 15 is engaged or disengaged. The latch 16 is biased forward toward the handle 10 by latch return springs 17 and 18 accommodated in the other end portion 12 of the housing 2 .

The lock device 21 is accommodated in the other end 12 of the housing 2; when the rotor 19 is in the unlocked position, the lock device 21 can be pushed in toward the direction intersecting with the latch 16; and when the rotor 19 is in the locked position , the lock device 21 cannot be pushed in. In the lock device 21, an operation part 20 is provided, and by the operation part 20, when the lock device 21 is pushed into the lock device 21, the lock bolt 16 can be driven toward the stop claw part 14 of the lock bolt 16 and the stop receiving part 15 of the lock handle 10. The direction in which the engagement relationship between is released is reversed. The lock device 21 is biased to slide in the front direction of the housing 2 by a lock device return spring 22 accommodated in the other end portion 12 of the housing 2 .
