[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closing device for stopping a sliding door such as a lavatory at an arbitrary position.

[0002]

2. Description of the Related Art Conventionally, to stop a sliding door such as a lavatory or other sliding door at a desired position for ventilation, a magnet provided on the rail at the tip of the rod while the rod is raised by a slide for photographing. Magnetically or press a rubber cushion.

Further, in order to release the stop of the sliding door, the above magnetic attachment and pressing are released while the rod is lowered by the slide for photographing.

According to the above-mentioned structure, when the stop of the sliding door is released, the photograph is slid, which is troublesome.

Therefore, as shown in Japanese Patent Application Laid-Open No. 3-161674, when the photograph is pushed up, the upper end of the rocking body is pressed against the guide rail, and the pin and the locking projection that move up together engage and rock. Since the descent of the moving body is regulated, the braking state is maintained.

Next, when the sliding door is slid, the swinging body swings due to the pressure contact between the upper end of the swinging body and the guide rail, so that the continuous pin is disengaged from the locking projection, and the lowering regulation of the swinging body is released. The braking state is released by the descent of the moving body.

[0007]

According to the above configuration, when the pin is raised along the slope of the locking projection,
Since there is no guide, the pin will come off the slope if a slight lateral shake occurs on the oscillator. Therefore, there is a problem that the braking force cannot be applied unless the sliding door is completely stopped.

Therefore, an object of the present invention is to provide a closing device for a sliding door in which trouble does not occur during a braking operation.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a vertical passage which is provided inward from either the upper frame surface or the lower frame surface of a sliding door, Operation of a slider that is inserted / retracted and rotatably inserted, a braking member that is provided at the tip of the slider in the protruding direction and that slides in the sliding direction of the slider, and that provides a protruding output, and an operating member exposed on the surface of the sliding door A rod provided inside the sliding door connected to the slider so as to rotate freely and to rotate freely, a spring for applying a restoring force to the rod in a direction opposite to the slider, and an end portion of the slider of the sliding door. A slide pin that can be retracted and provided so that the tips opposite to each other by the applied pressing force project from the peripheral surface parallel to the sliding direction, and the slide pin in the protruding direction of the slider on the wall surface of the passage. Wherein during de and receiving unit which slide pins previously having passed through the tapered surface and the tapered surface portion which is provided so as to gradually immerses the slide pin is provided to engage, the slide pin to the opposite side edges of the tapered surface portion guides And a guide path that is provided on the wall surface of the passage so as to return the slide pin that is disengaged from the receiving portion to immediately below the tapered surface portion, and is parallel to the tip end surface of the braking member in the sliding direction of the sliding door. The closing device for the sliding door includes a notch part provided so that a part of the sliding door contacts the rail.

[0010]

When the sliding door which is slid in the closing direction is closed at an arbitrary position, when the rod is lifted by operating the operating member, the slider is lifted and the braking member is pressed against the rail, so that the sliding door stops sliding. . At this time, as the slider rises, the slide pin is retracted by the tapered surface portion, the slide pin is prevented from coming off the tapered surface portion by the guide portion, and the braking member rises due to the contact between the rail and the tip surface of the braking member. Since it stops, the slider and rod rise.

When the slide pin passes the upper end of the tapered surface portion, the slide pin is released from the sinking state.
The tip of the protruding slide pin rides on and engages with the receiving portion. Therefore, the slider is prevented from descending together with the rod, the pressing state of the braking member against the rail is maintained, and the sliding door is closed.

In order to release the above-mentioned closed state, when the sliding door is slid a little in either direction, the braking member is rotated by a part of the upper end surface of the braking member pressed against the rail, so that it slides from the receiving portion. The tip of the pin comes off,
The engagement relationship between the receiving portion and the slide pin is released. For this reason, the spring lowers the slider together with the rod,
The pressing of the braking member against the rail is released.

The slide pin that descends together with the slider returns to the position immediately below the tapered surface portion by the guide path.
