Description

[Detailed Description of the Invention] The present invention relates to a drive device for driving a lever handle locking device attached to an entrance door.

Conventionally, the mounting position of the handle provided on the lock had to be changed depending on the opening/closing direction of the door, but when the mounting position of the handle was changed, the drive rod provided on the handle was connected to the notch of the rotating member of the locking device. There was a drawback that engagement could not be achieved.

The present invention was developed by focusing on this drawback, and its purpose is to prevent the protrusion of the drive rod provided on the handle even when the nozzle is installed vertically or horizontally. The lever handle drive device has a lever handle that operates a latch bolt by engaging with an engaging notch provided oppositely on the peripheral edge of a rotating plate.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
One end of the handle 2 is fitted into the fitting hole 1f, and the drive rod 3 is inserted into the recess 2c of the fitted end.
After fitting the bulge 3a formed at one end, a through hole 3b formed in the wall surface of this recess 2C and the wall surface of the bulge 3a.
, 2b to connect the handle 2 and the drive rod 3, and both ends of the pin 4 are provided to slightly protrude outside the handle 2, and one end edge of the handle fixing member 5 is attached to both ends of the pin 4. After fitting the notch 5a formed in the
A screw 6 is passed through a hole 5c provided in the bent portion 5b of the other end of the handle fixing member 5, and then this screw 6 is screwed into a screw hole IC provided in the opening peripheral portion 1b of the form body 1.

Further, the protrusion 3C provided at the tip of the drive rod 3 is engaged with an engagement notch 7a provided on the peripheral edge of the rotating plate 7 so as to face each other.

Both ends of the pair of connecting rods 9 are pivoted with pins 10 to connect the rotating plate 7 and the rotating operating member 8 forming the operating rod 8a for operating the latch bolt (not shown) with a pair of connecting rods 9. It's a shame.

Also, a center hole 8b of the rotation operation member 8 is formed, and this hole 8
A square shaft 11 for operating a dead bolt (not shown) is inserted into b.

As described above, the present invention includes a handle that is pivotally supported so that the mounting position can be changed via a handle fixing member that is detachable from the lid frame, and a drive rod that has one end fitted to the base end of the handle. A protrusion provided at the other end of the drive rod, a rotation plate formed with a plurality of engagement notches that engage with the protrusion, and a rotation operation member formed with an operation rod for operating the latch bolt; A pair of connecting rods are connected to the rotating operation part and the rotating plate with a pin. Since the protrusions are made to engage with each other, the protrusion of the drive rod that engages with the engagement notch can be changed by changing the mounting position of the bundle and engaging with the other engagement notch. This has the effect that the locking device can be operated without any trouble even if the position of the bundle is changed at times.
