DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In a locking device for locking a sickle of a sliding door lock, a gap may be formed between the sliding door and the door frame or conversely depending on the mounting position of the sickle and the locking device. The piece may not be completely locked, or the sliding door may not be properly closed and fixed. SUMMARY OF THE INVENTION The present invention relates to a sliding door lock member in which a locking device for locking a sickle of a sliding door lock can be moved in the front-rear direction to adjust a position for locking the sickle in order to properly close and fix the sliding door. It relates to a stop device.

2. Description of the Related Art Hitherto, Japanese Utility Model Publication No. 58-46194 has proposed a device for adjusting the movement of a stopper in the front-rear direction. In this invention, the rotating plate is rotatably supported by a pin, and a female screw is attached to the hole of the rotating plate so that the female screw can freely rotate, and the head of the male screw screwed to the female screw is exposed on the front surface of the box. Then, the male screw is turned by a screwdriver to turn the turning plate for adjustment.

[0003]

In the adjusting mechanism of the above-mentioned conventional example, a female screw member different from the rotating plate is necessary structurally, and four parts including a male screw and a pin are indispensable. There is a problem that the cost increases, and an object of the present invention is to realize a mechanism that can be adjusted with a small number of parts.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a sliding door lock member for locking a sliding door sickle to a receiving portion of a locking device movably attached to a mounting device. In the stopping device, the mounting member is provided with a guide plate portion having a substantially arc shape when viewed from the side, and the locking member is provided with a sliding contact plate portion that directly or indirectly contacts the guide plate portion. Is designed to be slidable with the tightening screw along the sliding contact plate by loosening the tightening screw, and fixed by tightening.

[0005]

When the tightening screw is loosened with a screwdriver or the like and the tightening screw is moved as it is, the locking member slides along the substantially arc-shaped guide plate portion, and the receiving portion moves in the front-back direction. Then, if the tightening screw is tightened at an appropriate position, the position where the sickle piece is locked is adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case 1 has an open front surface, in which a mounting fixture 2, a locking fixture 3 and a tightening screw 4 are accommodated, the front side is closed by a fixing plate 6, and the tightening screw 5 is closed. It is screwed together, closed with the surface plate 7, and caulked at the upper and lower mounting holes (no symbol).

The fixture 2 has a substantially U-shaped cross section. A guide plate portion 12 having a substantially circular arc shape is provided on an upper portion of the front plate as viewed from the side, and a vertically long adjustment hole 13 is provided therein. Has a screw hole 1
5 is provided. Grooves 14 are formed on both side plates so as to open rearward.

The locking member 3 has a receiving portion 8 provided above a substantially U-shaped section, and the front plate has a substantially circular sliding contact plate portion 9 in which a screw hole 10 is formed. It is provided. In addition, projections 11 are provided on the outer surfaces of both side plates.

[0009] The projections 11 of the locking device 3 are attached to the mounting device 2.
, The sliding contact plate portion 9 is brought into contact with the guide plate portion 12, the screw hole 10 is made to correspond to the adjusting hole 13, and the tightening screw 4 is inserted from the adjusting hole 13 into the screw hole 10. The fitting 2 and the locking tool 3 are integrated by screwing, and housed in the case 1. When the tightening screw 4 is tightened, the locking tool 3 is fixed to the mounting tool 2, and when loosened, the locking tool 3 can slide. Note that the sliding contact plate portion 9 only has to slide in an arc shape along the guide plate portion 12, and does not have to be in an arc shape.

The fixing plate 6 is provided with an opening 16 through which the sickle piece K of the sliding door enters and exits, and a vertically long adjustment hole 17. The tightening screw 5 is passed through the adjustment hole 17 so that the screw hole 1
Screw into 5. When the tightening screw 5 is tightened, the fixture 2 is fixed to the fixing plate 6, and when loosened, the fixture 2 can slide up and down. That is, the fixture 2 is
It is slidable up and down on the fixing plate 6 so that it can be fixed at a required position.

The front plate 7 has an opening 18 through which the sickle K of the sliding door enters and exits, and an operation hole 19 through which the head of the fastening screw 5 is exposed.
Is provided. The head of the tightening screw 4 screwed to the locking tool 3 is exposed from the opening 16 of the fixing plate 6 and the opening 18 of the surface plate 7. The surface plate 7 is for reinforcing the strength and improving the appearance, and is not always necessary and can be omitted.

Next, an assembling method will be described. The attachment 3 is attached to the attachment 2 with the fastening screw 4, and the attachment 2 to which the attachment 3 is attached is attached to the fixing plate 6 with the fastening screw 5. Then, the fixing plate 6 is placed on the surface of the case 1 and
Then, the locking member 3 is accommodated in the case 1, and the surface plate 7 is further superimposed on the surface thereof, and is caulked at the mounting holes (unsigned) at the upper and lower portions. The head of the fastening screw 4 is exposed from the opening 16 of the fixing plate 6 and the opening 18 of the surface plate 7, and the head of the fastening screw 5 is exposed from the operation hole 19 of the surface plate 7.

Next, the operation and movement will be described. When the tightening screw 4 is loosened and the tightening screw 4 is moved upward or downward as it is, the locking tool 3 slides in an arc along the guide plate 12 of the mounting tool 2, and the receiving part 8 moves forward and backward. It is fixed by tightening the tightening screw 4 and the adjustment in the front-rear direction is performed. When the tightening screw 5 is loosened and moved upward or downward as it is, the fixture 2 to which the locking tool 3 is attached slides linearly upward or downward, and the receiving portion 8 also moves in the vertical direction. When the tightening screw 5 is tightened, it is fixed and vertical adjustment is performed.

[0014]

As described above, according to the present invention, it is possible to adjust the movement of the locking member in the front-rear direction with a small number of parts, and to reduce the cost.
