Also, when caring for the bathing of the elderly and the physically injured, a sliding door that can open the entrance to the bathroom is preferable, and a sliding door with three doors is more convenient.

[0004]

However, in order to make a three-sliding door or the like, the width per sliding door becomes smaller and the sliding door becomes longer in the vertical direction, so that the sliding door rattles and the smooth opening and closing is difficult. The sliding door may slip off the rail.

As a sliding door which is prevented from coming off the rail, Japanese Patent Publication No. 57-17156 discloses a structure of a sliding door sash, that is, a sliding door in which a guide metal fitting is installed along the rail. With this configuration, there is a step in the threshold, so there is a problem in safety measures for the elderly and physically injured.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a sliding door that does not come off from the rail and is suitable for the entrance to the bathroom.

[0007]

The sliding door according to the present invention comprises:
A sliding door that rides on a sill, two pieces of locking claws that are inserted into gaps on both sides of a rail on which the sliding door rides, a locking operation guide that presses the locking claws of the two pieces in a direction that narrows the tip end spacing, It is an object of the present invention to achieve the above-mentioned object by a structure provided with an operation knob for activating or releasing the pressing function of the locking operation guide.

[0008]

With the above construction, normally, the locking operation is performed by inserting two pieces of the locking claws into the gaps on both sides of the rail on which the sliding door rides, for example, the gap with the adjacent rail, and operating the operation knob. The guide presses the two locking claws in the direction of narrowing the front end spacing to narrow the front end spacing and prevent it from opening, thus preventing the sliding door from coming off the rail.

When removing the sliding door, the pressing force of the locking operation guide, which has narrowed the distance between the tips of the two locking claws, is released by operating the operating knob, and the sliding door is inserted into the gaps on both sides of the rail on which the sliding door rides. The sliding door can be removed from the sill while pulling out the two pieces of the locking claws that had been used.

Incidentally, the sill has a waterproof function, and a sill of an entrance / exit can be constructed without a step.
