ワー１３を軸支持部材３に取付けても良い。 As shown in FIG. 1, a horizontally opening recess 32 is formed in the vertical frame 31 of the entrance and exit, and the fixed support plate 1 is screwed to the vertical frame 31 so as to cover the opening of this recess 32. A vertically long rectangular swinging member entry/exit opening 2 is formed in the support plate 1, and a shaft support member 3 having a U-shaped vertical cross section is attached to the lower edge of this opening 2 so as to extend inwardly. The pivot shaft 7 of the swinging member 6 is attached to the member 3 in the following manner so that it cannot be seen from the front. That is, the shaft support member 3 has a pair of upper and lower support pieces 4 facing each other, and as shown in FIG. A long shaft insertion hole 5 is formed therein. A pivot shaft 7 is fitted into these long shaft insertion holes 5, and a shaft mounting portion 8 of the swinging member 6 is fitted into this pivot shaft 7. As shown in FIG.
is integrally formed with the shaft mounting portion 8 and the shaft mounting portion 8, and when the door 12 is closed,
It has a first swinging piece 6A facing in the front-rear direction, and a second swinging piece 6B connected to the free end of the first swinging piece 6A and facing in the left-right direction in the same state. The free end of the swinging piece 6B passes through the opening 2, and the plate 10 is attached to the free end.
A door 12 is attached to this plate 10. As clearly shown in FIG.
A cam follower 13 is attached to the cam follower 13 in the following manner. That is, a short cylinder 15 is fitted in a portion of the pivot shaft 7 between the support pieces 4, a pair of arms 14 are provided horizontally at the upper and lower ends of the short cylinder 15, and a cam follower is installed between these arms 14. 13 is attached via a pin 16. A plate cam 18 against which the cam follower 13 contacts is attached to the shaft support member 3, and the plate cam 18 has a cam surface 17 that bulges out toward the pivot shaft 7 as it goes toward the opening 2. , this board cam 1
8 and the cam follower 13, the following motions are given to the pivot shaft 7. That is, when the door 12 is in the closed state, the cam follower 13 comes into contact with the left end of the cam surface 17, and the pivot 7 is at the farthest position from the opening 2 in the long shaft insertion hole 5, and the door 12
When the cam follower 13 is opened, the cam follower 13 moves on the cam surface 17, and when the door 12 is fully opened, the cam follower 13 comes into contact with the rightmost end of the cam surface 17, and the pivot 7 moves inside the long shaft insertion hole 5. The opening 2 is positioned closest to the opening 2 of the opening 2. With this structure, when the door 12 is opened, the swinging member 6 swings and moves forward to the right as a whole. In other words, the opened door 12 is prevented from hitting the vertical frame 31. . A pin 19 is inserted into the front portion of the shaft insertion elongated hole 5 of the upper and lower support pieces 4 of the shaft support member 3.
The leaf spring 20 of 9 is stopped, and this leaf spring 2
One end of the 0 abuts the short cylinder 15 from the front, and the other end abuts the shaft support member 3 to bias the swinging member 6 rearward. In addition, an intervening material 2 made of synthetic resin or the like is provided between the swinging member 6 and the shaft support member 3 so that the above-mentioned movement can be performed smoothly.
2 is provided. Furthermore, in order to maintain the state when the door 12 is opened to a predetermined position, a door stopper 23 is provided on the shaft support member 3, and a spherical locking piece 24 is provided on the cylindrical member 21 of the door stopper 23 at the top and bottom. It is fitted so as to be movable and is biased upward by a spring 25. A locking groove 26 (see FIG. 3) is formed at the lower end of the swinging member 6, and the door 12
When opened to a predetermined position, the locking piece 24 is fitted. With this structure, when the closed door 12 is opened to a predetermined position, the swinging member 6 reaches directly above the door stopper 23, and
Since the locking piece 24 biased by the spring 25 fits into the locking groove 26, the door 12 is kept open in this state. When a force exceeding a set value is applied to the door 12 in the open state, the locking groove 2
6 is released from the locking piece 24, and the door 12 closes by itself due to the action of the leaf spring 20. Note that this door stopper 23 only needs to have a suitable stopper mechanism, or may not be provided. Further, the shaft support member 3 may be provided above and below the opening 2, and the elongated hole 5 may also be of such a type that its longitudinal direction is oriented left and right or front and back. Furthermore, the plate cam 18 may be attached to the pivot shaft 7 and the cam follower 13 may be attached to the shaft support member 3.

ちで閉じることが出来る。(Effect of the invention) As described above, according to this invention, the pivot 7 for opening and closing the door 12 is located in the recess 32 of the vertical frame 31, and the pivot 7 of the swinging member 6 is accessible from the outside of the door. Since it is invisible, the door opening/closing device can be made extremely superior in terms of design, and since it is impossible to break the pivot 7, it is possible to make the door opening/closing device excellent in terms of crime prevention. Further, the swinging member 6 is moved forward or left and right by the action of the cam mechanism, so that when the opened door 12 is closed, the door 12 approaches the vertical frame 31. Therefore, the door 12 can be closed closer to the vertical frame 31.
