It is preferable that the coupling angles of the first support piece 221a and the second support piece 221b form an obtuse angle so that the contacting process and the pressing process can be smoothly performed. At this time, the above-described pressing piece 273 comes into contact with the surface forming the obtuse angle.

By forming the first support piece 221a and the second support piece 221b at an obtuse angle in this way, the pressing piece 273 prevents entry into the space between the first support piece 221a and the second support piece 221b. When the door 10 is opened, interference when the pressure piece 273 separates from the first support piece 221a and the second support piece 221b can be prevented.

The third soft member 250 is installed between the first jamming prevention plate 220 and the second jamming prevention plate 240 to increase the angle between the first jamming prevention plate 220 and the second jamming prevention plate 240. Since the door 10 is deformably provided so as to be changeable, when the door 10 is in a closed state, it is bent so that the angle between the first jamming prevention plate 220 and the second jamming prevention plate 240 is minimized, and the door 10 In this maximum open state, it is unfolded and deformed so that the angle between the first jamming prevention plate 220 and the second jamming prevention plate 240 is maximized.

A first accommodating groove 222 and a second accommodating groove 241 are formed on the rear surface of the first jamming prevention plate 220 and the rear surface of the second jamming prevention plate 240, respectively. Both ends of the third soft member 250 are inserted and fixed to 222 and 241, respectively, to combine the two components.

The shape of the third soft member 250 and the first and second accommodating grooves 222 and 241 to which both ends thereof are coupled can be freely modified as long as the third soft member can be maintained, but, for example, the third soft member The central portion of the member 250 is formed in a flat plate shape, both ends are formed in a cylindrical shape, and the first and second accommodating grooves 222 and 241 are formed in a partially cut pipe shape to form both ends of the third soft member 250. may be coupled to the first and second receiving grooves 222 and 241 in an interference fit form.

At this time, guide protrusions are formed on the cylindrical portions of both ends of the third soft member 250, and corresponding guide grooves are formed on the inner circumferential surfaces of the first and second accommodating grooves 222 and 241, so that the third soft member 250 ) may be appropriately adjusted.

Finally, the present invention installed a soft member on each joint in order to rotatably combine each component. By using the soft member in this way, body parts such as fingers are moved between each component of the present invention, or each component. Even if it enters between the field and the door or door frame, since the soft member is deformed and absorbs the shock, it is possible to prevent injury to the body part.

In addition, when using a soft member, since there is no configuration that causes friction during rotation, it is possible to prevent noise due to friction or deterioration of each part due to frictional heat, which can prolong life and prevent occurrence of unpleasant noise. It works.

As described above, although it has been described with reference to the preferred embodiments of the present invention, those skilled in the art will variously modify and change the present invention within the scope not departing from the spirit and scope of the present invention described in the claims below. You will understand that it can be done.
