Description of the Related Art A hinged door that cannot receive the lower end of a door by a door stop or a hanging sliding door that does not have a guide rail on the floor side has an unstable lower end when closed. That is, in the case of a hinged door, the lower end of the door at the closed position is in a state in which it can swing inward beyond the closed position, and in the case of a sliding door, the lower end of the door at the closed position is the door. In a state in which it can swing inward and outward directions perpendicular to the opening and closing movement direction.

A floor-side elevating pin-type steady rest device that is pulled up and fitted in, and a recess is provided on the floor side, and a pin that can be raised and lowered held at the ascending limit position by a spring is provided at the lower end of the door, A door-side elevating pin type steady rest device has been conceived in which the elevating pin is lowered by magnetic attraction when the door reaches the closing limit position and fitted into a recess on the floor side.

やはり装置が大型になる問題点があった。However, in the steadying device of the floor-side lifting pin type, there is a great possibility that dust will accumulate in the recess for accommodating the floor-side lifting pins and smooth pin lifting operation will not be performed. In the door-side lift pin type steady rest device, when the lift pin arrives directly above the floor-side recess, the lift pin is instantaneously moved by the magnetic attraction force and for a required stroke against the urging force of the spring. Not only do they require a large and strong magnet, but also in any type of steady rest device, when the door is opened, the elevating pin is pushed out vertically on the slope of the recess, and the door is opened. This results in a large resistance to the opening operation of the
The lifting pins must also be strong enough to withstand the resistance.
Again, there was a problem that the device became large.

The casing 22 is held in a substantially horizontal retreat posture in contact with the stopper surface 32 on the casing 22 side. When the sliding door 21 in such a state is closed, when the sliding door 21 reaches just before the closing limit position, the magnet 31 of the movable piece 23 is
, And the movable piece 2
3 is pulled down against the urging force of the spring 30, and as shown in FIG. 5A, the movable piece 23 swings downward around the support shaft 29 to assume an obliquely downward posture, and the tip thereof has the recess 1
Opening both side walls 3 of the movable piece introduction part 37 at the entrance of 3
It contacts the inclined bottom surface 36b between 6a. Then, with the subsequent closing movement of the sliding door 21, the movable piece 23, the tip of which abuts on the inclined bottom surface 36 b, is guided by the outwardly opened side walls 36 a and fits into the recess 33, and the sliding door 21 is moved. When the movable member 23 reaches the closing limit position, the left and right side surfaces 23b of the movable piece 23 are sandwiched between the locking surfaces 33b of the concave portion 33, and the lower end of the sliding door 21 swings inward and outward directions perpendicular to the opening and closing movement direction. Is blocked. At this time, the magnet 31 of the movable piece 23 comes closest to or contacts the inclined bottom surface 33a of the concave portion 33,
The obliquely downward posture of the movable piece 33 is strongly held.

ができる。As described above, according to the door steadying device according to the first aspect of the present invention, the lower end of the door that has reached the closing limit position swings inward beyond the closing limit position. To
It is possible to reliably prevent this by fitting the concave part on the floor side with the movable piece on the door side, but since only the concave part is provided on the floor side, the movable piece is provided at the lower part of the tip of the hinged door, It is extremely unlikely that the accumulated dust will interfere with the normal operation of the movable piece. Moreover, the movable piece provided at the lower end of the hinged door has one end pivotally supported so that it can swing up and down,
Because the magnetic attraction force swings from a substantially horizontal retreat position to an obliquely downward position, the required magnetic attraction force is smaller than when the entire lifting pin is pulled down by the magnetic attraction force, and a small magnet is used. It is possible to reliably perform the desired operation while using the configuration. Also, when the hinged door is opened, the movable piece in the obliquely downward position, whose tip is parallel to the door opening movement direction and on the opposite side to the door opening movement direction, is pushed out while swinging upward from the recess. Compared with the case of pushing out, the resistance applied to the door side is extremely small, and the movable piece can be smoothly and reliably returned to the original retracted posture.

The recess can also be small. Furthermore, according to the configuration of the third aspect, even if the gap between the hinged door and the floor slightly changes, the closing limit position of the hinged door can be made constant, and the gap between the hinged door and the floor can be adjusted. Therefore, it is not necessary to finely adjust the position of the recess on the floor side in the opening and closing direction of the opening door. Further, according to the configuration of the fourth aspect, the portion protruding inward from the lower end of the hinged door can be reduced.
