しないで出入シすることが多く、この場合には身体を横
にずらせてから通らなければならない。``Prior Art'' Conventional doors have a structure in which either the left or right side edge is hinged to the side wall of the entrance, so when a passerby tries to open the door, the door swings wide using the hinge as a fulcrum. It is something to do. Therefore, because the door swings open like this, you have to take a step back when you pull it forward, and you often enter or exit without opening the door fully, in which case you turn your body to the side. You have to move it and then pass.
また、従来のドアーは前記の如くであるから、特に身体
障害者や車椅子使用者にとっては、ドアーの開閉がスム
ーズにいかず、きわめて骨が折れることであったのであ
る。Moreover, since conventional doors are as described above, opening and closing the doors cannot be done smoothly, which is extremely tiring, especially for physically disabled people and wheelchair users.

ある。When you approach the doors 1 and 2 and pull the opening/closing operating lever 19 toward you, the operating lever 19 rotates about its longitudinal center axis as a pivot point, as shown in FIGS. 9 and 10. , its lower end moves toward the rear. Accordingly, the base of the lower support arm 7 is pressed and rotated in the horizontal direction. As a result, the main shaft 8
can be rotated. The door support shaft 4 supported by the tip of the support arm 7, which rotates horizontally rearward with the rotation of the main shaft 8, is arranged in a circular arc with the entire center of the main shaft 8 as shown in FIGS. 3 and 12. Move backwards as if tracing a trajectory. At this time, the door support shaft 4 gradually moves rearward while sliding within the long hole 13a of the horizontal swinging rod 13, but is supported by the horizontal swinging rod 13 so as to be movable in its axial direction. Further, rotation of the support shaft 4 itself is prevented by the rotation restriction plate 14 which is urged toward the door support shaft 41C by the expansion spring 16. That is, the axis P of the shaft portion 4a of the door support shaft 4 is always aligned with the support shaft 12.

Then, the door support shaft 4 on the door 2 side moves forward via the links 23, 22, 23'. Therefore, the door 1 and the door 2 open back and forth in opposite directions.
また、扉1,2を通シ抜けた時には、通シ抜けた側にあ

る。"Effects of the Invention" The present invention has the above-mentioned configuration and operation, and when opened, the pair of left and right doors rotate while moving outward horizontally, and finally become parallel to the side wall of the entrance. Because it is a traditional swing-type door, it does not move backwards when opening,
There is no need to move sideways, and you can continue straight ahead. Therefore, it is especially good for people with physical disabilities and wheelchair users, who can get in and out smoothly. Additionally, the left and right doors open fully parallel to the side walls of the entrance, making it ideal for use in narrow passages. Furthermore, since it opens fully and quickly with a few movements, passing through is smooth.In addition, the rhythmic opening and closing movement of the left and right doors creates a good impression on passersby, and has many practical uses and benefits. There will be 1.
