The sliding door 1 and the embedding member 12 are stabilized when they are buried.

With the above-mentioned structure, the finger-stuffing prevention device of this embodiment has the structure shown in FIG. 1 when the sliding door is fully opened.
As shown in, the movable member 5 of the door closing prevention unit 3 is in a state in which the tip end portion is inclined downward with the connecting shaft 11 as a fulcrum. This is because the weight of the first magnet 7, the shock absorber 6, the lid 8 and the own weight of the movable member 5 provided inside the movable member 5 tilts the tip of the movable member 5 downward with the connecting shaft 11 as a fulcrum. However, since the connecting portions 5d and 5d of the movable member 5 are in contact with the recess bottom surface 10e of the mounting base 10, an appropriate angle is maintained. In addition, the balance adjusting spring 9 uses the connecting shaft 11 as a fulcrum, one end contacts the contact surface 10f of the mounting base 10, and the other end contacts the contact surface 5h of the movable member 5. The urging force is applied in a direction to push the movable member 5 upward.

As a result, the movable member 5 of the door closing prevention unit 3 maintains a positional relationship capable of interfering with the upper end portion 1a of the sliding door 1, and the urging force of the balance adjusting spring 9 exerts a small force on the door groove. It is possible to move in the direction of 2a.

As the poles repel each other, the tip of the movable member 5 is lifted upward, moved from the position where the closing of the sliding door 1 with the upper end 1a is blocked to the retracted position, and hits the bottom surface 2b of the door groove. It comes into contact with them. From this state, the sliding door 1 is further closed, and when the sliding door 1 is completely closed, as shown in FIG. 11, the first magnet 7 of the door closing prevention unit 3 is closed.
Since the second magnet 14 of the door closing prevention release unit 4 and the second magnet 14 are apart from each other, the movable member 5 abuts along the upper end surface of the sliding door 1. Therefore,
It does not hinder the closing of the sliding door 1. Further, in this state, the protruding member 1 of the door closing prevention releasing unit 4
3 is housed inside the embedding member 12.

On the other hand, when the sliding door 1 is closed faster than the above predetermined speed, as shown in FIG. 12, the N pole of the first magnet 7 of the door closing prevention unit 3 and the first pole of the door closing prevention releasing unit 4 are closed. The N pole of the two magnets 14 repel each other, and the movable member 5
Although the leading end of the sliding door 1 retreats upward, the upper end 1a of the end face of the sliding door 1 is exposed from the notch 5e at the leading end of the movable member 5 of the door closing prevention unit 3 by the time of retreating to the retracted position. The shock absorber 6 interferes with the upper end portion 1 a of the sliding door 1. That is, the door closing prevention unit 3 receives the sliding door 1 by the shock absorber 6 and plays a role of a sticking rod with respect to the sliding door 1. As a result, even when the sliding door 1 is closed quickly, it is possible to prevent fingers from being caught between the sliding door 1 and the door frame 2.

The shock absorber 6 is made of, for example, the above-mentioned hanenite, which is a rubber material that has excellent vibration absorbing properties, hardly repels even when receiving an external force, and absorbs energy. By this, the sliding door 1 is closed vigorously,
Even when the upper end of the sliding door 1 interferes with the shock absorber 6, the interference energy is absorbed, and it is possible to prevent the rebound of the sliding door 1 and the generation of a large interference sound. In addition, it is possible to prevent damage to the finger-stuffing prevention device for the door.

Further, the movable member 5 is provided with a positioning recess 5b which is an elongated hole, but the sliding door 1 is vigorously closed, and the upper end portion 1a of the opening / closing side end surface of the sliding door 1 interferes with the shock absorber 6. At this time, the shock absorber 6 is slightly deformed due to interference and is pushed toward the connecting shaft 11. At this time, the first magnet 7 in the shock absorber 6 also moves in the direction of the connecting shaft 11 from the normal position due to the deformation of the shock absorber 6, but the positioning recess 5b has the first magnet 7 therein. Acts as a guide when moving backwards.

The distance S between the bottom surface 2b of the door groove and the upper end surface of the sliding door 1 is slightly different depending on the sliding door 1.
The adjustment screw 18 is provided so that when the adjustment screw 18 is tightened, the adjustment screw 18 comes into contact with the recess bottom surface 10e of the mounting base 10, and when the adjustment screw 18 is further tightened, the adjustment screw 18 moves as shown in FIG. The tip of the member 5 is pushed upward. That is, the rear end portion of the movable member 5 becomes the force point, and the tip end portion of the movable member 5 becomes the action point and is lifted up with the connecting shaft 11 as the fulcrum. Thereby, the bottom surface 2b of the doorway
The upper end portion 1a of the opening / closing side end surface of the sliding door 1 and the movable member 5 of the door closing prevention unit 3 can interfere with each other in the opened / closed state of the sliding door 1 according to a slight difference in the distance S between the sliding door 1 and the upper end surface of the sliding door 1. It is possible to adjust the position so as to have a proper positional relationship.

Further, the projecting member 22 is formed to have substantially the same shape as that of the projecting member 13 of the first embodiment, and a circular hole 22a having a diameter about the screw head of the magnet position adjusting screw 24 is formed in the central portion of the tip surface. ing.

In the above structure, when the magnet position adjusting screw 24 is tightened from the hole 22a of the projecting member 22 using a screwdriver or the like, the second magnet 23 becomes the magnet position adjusting screw 2
4, the second magnet 23 moves in a direction away from the open / close end surface of the sliding door 1 when the magnet position adjusting screw 24 is loosened. Therefore, when the magnet position adjusting screw 24 is loosened, the distance between the opening / closing side end surface of the sliding door 1 and the second magnet 23 is increased, so that the movable member 5 of the door closing prevention unit 3 is closed even when the sliding door 1 is closed at a high speed. Can be easily pushed up.

On the other hand, when the magnet position adjusting screw 24 is tightened, the distance between the opening / closing side end surface of the sliding door 1 and the second magnet 23 becomes shorter, so that the second magnet 23 has the upper end 1a of the opening / closing side end surface of the sliding door 1. The repulsive force is not applied to the first magnet 7 of the door closing prevention unit 3 until it just interferes with the door closing prevention unit 3, and the movable member 5 does not move when the upper end 1a of the open / close side end surface of the sliding door 1 approaches. Can be pushed up slowly. This makes it possible to appropriately adjust the closing speed of the door when the door is completely closed by the door closing prevention means.
