Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle device for a so-called grip-type door lock that is operated when a Tibolt portion of a locking device provided on a door is retracted into the locking device.

Conventionally, many of the handle devices for this type of door lock are of the lever, knob, or thumb lever type.
All of them have complicated structures and lack smooth operation functions.
There was a drawback.

It is an object of the present invention to eliminate such drawbacks.

This problem is to make the handle of the door lock which is operated when retracting the latch bolt into the locking device a grip type, and to simplify the structure, and this problem can be fully and satisfactorily achieved by the following means. be.

In the present invention, the grip that can be pulled by hand faces the inside of the handle case, and when the grip is pulled toward the handle case, the pin provided on the fixed piece fixed to this grip is inserted into the elongated hole provided in the latch bolt drive rod. This is a door lock handle device in which the latch bolt drive rod is operated while sliding therein, the gist of which is as set forth in the claims.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a known locking device, in which a latch bolt 6 is retracted into the locking device A by an elevating plate 10.

Reference numeral 1 denotes a lock case, and within this lock case 1, a dead bolt plate 2 and a latch bolt plate 3 that move laterally, and an elevating plate 10 that moves up and down by the operation of a latch bolt drive rod 4 are provided.

A deadbolt 5 is provided at the end of the deadbolt plate 2 and a latch bolt 6 is provided at the end of the latch bolt plate 3. An opening 17 is provided through which the deadbolt 5 and the latch bolt 6 are moved forward and backward from the front 7 of the lock case 1. 1// is provided at the front 7.

The deadbolt 5 has a cam 19 rotated by the cylinder lock S.
It moves forward and backward.

The latch bolt 6 should always protrude from the front 7.
It is biased φ by a spring 9 connected to a receiving plate 8 implanted in the lock case 1.

In addition, the elevating plate 10 provided inside the lock case 1 has vertical grooves 1 in the vertical direction.
1 is opened, and a guide pin 12 protruding from the lock case 1 is fitted into the vertical groove 11 of the lock case 1 to guide vertical movement of the elevating plate 10.

A spring 13' provided between the bent piece 14 of the elevating plate 10 and the flange receiving plate 13 planted in the lock case 1 keeps the elevating plate 10 pressed downward at all times. A bent piece 4 provided on the lower edge 10' of the lifting plate 10 is exposed to the outside from the lock case 1, and when this bent piece 14 is pushed up with the latch bolt drive rod 4, the lifting plate 10 rises against the spring 13'.

At this time, one end of the rotating plate 15 connected to the elevating plate 10 and the latch bolt plate 3 is pivoted to a shaft 16 implanted in the lock case 1, and the beak end of the rotating plate 15 is The provided pin 17 is inserted into the engagement hole 17' of the latch bolt plate 3.
furthermore, a slide bin 18 is attached to the back surface of the elevating plate 10.
This slide bin 18 is brought into contact with the side edge of the rotating plate 15.

Therefore, when the bent piece 14 of the lifting plate 0 is pushed up by the latch bolt drive rod 4, the lifting plate 1° is raised.

At this time, the slide bin 18 moves upward while contacting the side edge of the rotating plate 15, so that the rotating plate 15
Since the latch bolt plate 3 is rotated around the pivot plate 10, the pin 17 provided on the pivot plate 10 moves the latch bolt plate 3 to the right in FIG. The lock device A is such that when the latch bolt plate 3 moves in this way, the latch bolt 6 protruding from the front 7 can be retreated into the lock case 1.

In the lock device in which the elevating plate is moved from outside the lock case 1, the handle device of the present invention will be explained with reference to FIGS. 3 and 4.

3 and 4 are partially cut away vertical sectional side views of the present invention, in which FIG. 3 is before operation, and FIG. 4 is an operation state diagram after operation.

The handle case 20 has a curved portion B that is gripped by the hand. A drive shaft 21 inserted into a hole 19' of a cam 19 for moving the dead bolt 5 forward and backward, and a cylinder lock S connected to the drive shaft 21 are provided in the upper part of the handle case 20.

Further, an opening 22 is formed inside the handle case 20, and a grip 23, which can be pulled toward the handle case by hand, is exposed through the opening 22.

This grip 23 forms a split groove 23', and one end of this grip 23 is rotatably supported by a first pin 25 within the bolt case 20, and is fixed in the split groove 23'. A second pin 26 is fixed to one end of the fixed piece 24.

The second pin 26 is still fitted into the elongated hole 27 formed in the latch bolt drive rod 4. When the second pin 26 moves within the elongated hole 27, the latch bolt and drive rod 4 are rotated about the third pin 28 as a support shaft. Further, one end of the latch bolt drive rod 4 is rotatably attached within the torque case 20 by a third pin 28.

The tip of the rano bolt drive rod 4 is in contact with a bent piece 14 of the elevating plate 10 for retracting the dead bolt 5.

The grip 23 described above is biased by one end of a spring 29, and the other end of the spring 29 is in contact with the inner wall surface 20' of the handle case 20.

Since the present invention is configured as described above, the second

be rotated in the direction.

Since the present invention operates in this manner, the end of the latch bolt drive rod 4 pushes up the bent piece 14 of the lock device A. When the elevating plate 10 is raised once in this way, the rotating plate 15 is rotated about the shaft 16 by the slide bin 18.
17 moves the latch bolt plate 3.

When the Tibalt plate 3 moves in this way, the front 7
The protruding latch bolt 6 can be retracted into the locking device A.

The present invention provides a handle with a handle on the inside of the handle case, and when the handle is pulled toward the handle case, the second pin of the fixed piece slides in the long hole of the latch bolt drive rod, and the latch is activated. Since the bolt drive rod is raised, this elevation moves the elevating plate inside the locking device and also retracts the latch bolt into the locking device, which simplifies the structure and allows four fingers to be placed on the grip. This has the practical effect of allowing the grip to move smoothly during operation.
