BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a sliding door according to the present invention.

FIG. 1 is a side view of an essential part of an embodiment according to the present invention. The present embodiment is a sliding door 2 that rides on a sliding door 1 and is a two-piece latch that can be inserted into a gap on both sides of a rail 3a on which the sliding door 2 rides, in the illustrated example, a gap between the rail 3a and the rails 3b and 3c. A claw 4, a locking operation guide (not shown) for pressing in a direction to reduce the interval between the tips 12 of the two locking claws 4, and an operation knob 5 for operating or releasing the pressing function of the locking operation guide. The sliding door stopper unit 6 is attached to the lower part of the sliding door 2.

FIG. 2 is an exploded view showing an example of the sliding door stopper unit 6. As shown in FIG.

The main part of the sliding door stopper unit 6 includes a unit main body 7 which is inserted and fixed below the inside of the vertical frame of the sliding door 2 and a locking claw block 8 having two locking claws 4 connected at the root. The tip 12 of the two locking pawls 4 is engaged with the shoulder 9 of the locking pawl block 8 which is the upper half of the two locking pawls 4.
Locking operation guide 10 pressing in a direction to reduce the interval between
The operation knob 5 is configured to press and reduce the distance between the tips of the two locking claws 4 by moving the locking operation guide 10 up and down, or to release the pressing.

In the present embodiment, the locking claw block 8 is made of a hard synthetic resin, and the material is flexible and elastic. Since a certain shoulder portion 9 extends downward in a tapered shape, when the locking operation guide 10 engaged with the shoulder portion 9 is moved downward, the leading end interval between the two locking claws 4 is reduced. The pressing force acts on the shoulder portion 9 in the direction, and the leading end interval between the two locking claws 4 is narrowed, so that the two locking claws 4 cannot be pulled out from the gap between the rails.

When the locking operation guide 10 is moved upward, there is no pressing force for narrowing the interval between the tip ends of the two locking claws 4, and the two locking claws 4 can be pulled out of the rail gap. it can.

The unit main body 7 has a long hole 11 for adjusting the vertical position of the locking claw block 8 and mounting the locking claw block 8 on the locking claw block 8 in which the locking operation guide 10 is engaged with the shoulder portion 9. Insert the half part into the unit body 7 and adjust the adjustment screw 12
Thereby, the locking claw block 8 can be fixed to the unit main body 7.

That is, when the unit body 7 is mounted on the lower part of the sliding door, the two locking claws 4 can be inserted into the gap between the rail 3a on which the sliding door 2 rides and the rails 3b, 3c on both sides.
The vertical position is adjusted by the slot 11 so that the locking portion 4a at the tip of the rail is located slightly below the top 13 of the rail.

The pin 14 is inserted and mounted on the locking operation guide 10 through the shoulder portion 9 of the locking claw block 8, that is, the gap between the upper half portions of the two locking claws 4. It has a function of maintaining the positional relationship with the claw block 8 normally, and at the same time, guiding the vertical movement of the locking operation guide 10. Further, a function of positively opening the interval between the tips of the two locking claws 4 when the locking operation guide 10 is moved upward can be provided.

The operation knob 5 is attached to a side surface of the locking operation guide 10 so that the locking operation guide 10 can be moved up and down from outside when the unit body 7 is mounted on the lower part of the sliding door.

With the above structure, the locking operation guide 10 is moved downward by operating the operation knob 5 so that the rail 3a on which the sliding door 2 rides and the rails 3b, 3c on both sides are normally used.
The gap between the front end locking portions 4a of the two locking claws 4 inserted into the gap between the front end and the front end is narrowed by pressing in the direction of narrowing and the opening is prevented, so that the sliding door 2 does not come off the rail 3a. It is possible to provide a sliding door which can be smoothly opened and closed, and is suitable for a vertically elongated three-sheet sliding or the like.

When the sliding door is removed, the operation knob 5 is operated to move the locking operation guide 10 upward to release the pressing force that has narrowed the interval between the tip locking portions 4a of the two locking claws 4. , The rail 3a on which the sliding door 2 rides and the rails 3b, 3 on both sides
The sliding door 2 can be removed from the sill-shaped sill 1 while pulling out the two pieces of the locking claws 4 inserted into the gap between the sliding door 2 and the sliding door 2.

As mentioned above, the sash-shaped sill 1 can be provided with a necessary waterproof function at the entrance to the bathroom as described above to eliminate the step.

[0024]

As described above, according to the present invention, normally, two locking claws are inserted into the gaps on both sides of the rail on which the sliding door provided on the sill rides, and the operating knob is operated. The stop operation guide presses the two locking claws in the direction of narrowing the gap between the tips to prevent the gap between the tips from being opened and to prevent the sliding door from coming off the rail.
It is possible to provide a sliding door which is preferable for sheet sliding and the like.

When the sliding door is removed, the pressing force of the locking operation guide, which has narrowed the interval between the tips of the two locking claws, is released by operating the operation knob, and the sliding claw is inserted into the gap on both sides of the rail on which the sliding door rides. The sliding door can be removed from the threshold while pulling out the two locking claws from the gap.

It should be noted that the sill has a waterproof function, and can constitute an entrance sill without a step.
A suitable sliding door can also be provided for an entrance to a bathroom used by a physically handicapped person.
