DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door for properly closing and fixing a sliding door. The present invention relates to a locking device for a sliding door lock that can be adjusted.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open No. 9-78902 discloses an invention for adjusting the movement of a locking member in a vertical direction. This invention uses an adjusting screw which penetrates a long hole provided in a surface plate.
The receiving piece can be fixed in a vertically adjustable manner.

[0003]

In the above-mentioned prior art, the adjustment is performed by loosening the adjusting screw with a screwdriver, moving the receiving piece up and down, and then tightening the adjusting screw again. However, an object of the present invention is to enable adjustment with simpler operation.

[0004]

According to the present invention, in order to solve the above-mentioned problems, at least a stopper, a slide, a bridge and an adjusting screw are accommodated in a case and covered with a surface plate. In a locking device for a sliding door lock that locks a sickle of a sliding door lock with a locking device, the locking device and the sliding device can slide up and down together, and an adjusting screw can be rotated on the sliding device. The adjustment screw is screwed with a non-rotatable piece that can be moved back and forth, and the piece is provided with guided portions on both sides and engages with the oblique guide portions on both inner sides of the case. When the adjusting screw is rotated, the bridge body moves back and forth, the guided part is guided by the guide part, the sliding tool moves up and down, and the locking tool moves up and down together. It is.

[0005]

When the adjusting screw is rotated, the piece screwed to the adjusting screw moves back and forth, the guided portions on both sides are guided by the guide portion, and the sliding device moves up and down to engage the locking device. Also move up and down together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case 1 has an open front surface, in which a sliding member 2, a locking member 3, a frame 4, an adjusting screw 5 and side plates 6.6 are accommodated. Close with 7.

The sliding member 2 and the locking member 3 are integrated, and the integrated member includes sliding grooves 11 in the front-rear direction.
11 are provided, projections 9 are provided on the upper part, and projections 10 are provided on the lower part. An adjusting screw 5 screwed into the screw hole 12 of the bridge body 4 is rotatably attached to the slide body 2 and the locking body 3 by an E-shaped retaining ring 8. The provided guided portions 13 (which are projections in the present embodiment) are in sliding contact with the sliding grooves 11 and are slidably guided in the front-rear direction. Since the sliding tool 2 is integrated with the locking tool 3, it moves up and down together, and the locking tool 3 locks the sickle piece K of the sliding door lock. In addition, the locking device 3
Is not required to be integral with the sliding device 2 and may be any device as long as it can slide up and down together with the sliding device 2. Good.

The side plate 6 is provided with a guide portion 14 having an obliquely long hole, an upper and lower guide hole 15 at an upper portion, and an upper and lower guide hole 16 at a lower portion. This side plate 6.6
Is approximately the same size as the inner surface of the case 1 and is immovable after being housed in the inner surface of the case 1 and attaching the surface plate 7. The side plates 6 may be attached to the inner surface of the case 1 so as not to move, or the guides 14 may be provided on the side plate of the case 1 without installing a separate side plate. Is also good.

The surface plate 7 has an opening 17 through which the sickle K of the sliding door enters and exits, and an operating hole 1 through which the adjusting screw 5 that moves up and down is exposed.
8 is provided. The locking tool 4 is exposed from the opening 17 of the surface plate 7.

Next, an assembling method will be described. An adjusting screw 5 screwed with a piece 4 is rotatably mounted on an E-shaped retaining ring 8 on a united sliding device 2 and a locking device 3. The guided portions 13 are engaged with the guide portions 14, 14, and the projections 10 are engaged with the guide holes 16, respectively. The surface plate 7 is attached from the surface side of the case 1 so that the locking tool 4 is exposed from the opening 17 of the surface plate 7 and the adjusting screw 5 is exposed from the operation hole 18.

Next, operation and movement will be described. When the adjusting screw 5 is rotated, the bridge body 4 moves back and forth, and the guided portions 13 are guided by the guide portions 14 while slidingly contacting the sliding grooves 11 and move obliquely in the sliding direction. 2 and the latch 3 move together or downward.

[0012]

As described above, according to the present invention, there is an effect that vertical adjustment can be performed by a simple operation of simply turning the adjusting screw.
