Description

Anti-finger pinch safety door {FINGER PROTECTING SAFETY DOOR}

The present invention relates to a finger-trap prevention safety door, and more particularly, to a finger-trap prevention safety door that prevents a part of the body or an object from being pinched when a casement door rotates.

In general, building structures are divided into different spaces by a plurality of inner walls while the inside and outside are blocked so that privacy can be maintained, and access from the inside to the outside or from the outside to the inside or from the inside space A casement-type door is provided as a way to move. In addition, in a conventional casement door, a hinge or hinge is disposed between one side of the door and a door frame supported by a wall, and a handle is disposed on the other side of the door so that the user can hold the handle and pull or push to open and close the door. .

The casement type door has the advantage of being rotatably coupled to the door frame by a hinge, so that the process of opening and closing the door is facilitated. However, as a gap for rotation is formed between the door frame and the door, users' bodies or objects There is a problem that this pinching phenomenon occurs. In particular, accidents in which children's fingers are caught frequently occur in hinged doors, and when the door is closed while the fingers are caught, there is a problem that can lead to serious injuries.

Accordingly, in Korean Patent Publication No. 10-2021-0109274 (hereinafter referred to as 'prior literature'), a curved surface is formed on a door leaf and a door frame through a hinged door to prevent hand jamming, and the space between the curved surfaces is minimized. A technique for preventing an accident of pinching a finger is disclosed. Referring to FIG. 1 , the casement door including a door leaf 1, a door frame 2, a rotation shaft 3, a rotation connection part 4, and a connection member 5 is disclosed in the prior art document. At this time, the door leaf 1 includes a fan-shaped first curved portion and a panel portion, and the door frame 2 includes a second curved portion rotatably adhered to the first curved portion. And the door leaf (1) is rotated through the rotating shaft (3), and the door leaf (1) and the door frame (2) are detached through the rotation connecting portion (4) and the connecting member (5).

As described above, since the shape of one side of the door contacting the door frame is configured in a cylindrical shape, the gap between the door frame and the door frame does not change even when the door leaf rotates, thereby preventing jamming. However, structures that require replacement of all door frames, doors, or related accessories are difficult to apply to existing hinged doors, and in order to apply them, the structure must be changed through extensive construction, resulting in a lot of installation cost. In addition, there is a disadvantage in that work efficiency is lowered due to excessive separation and installation work during part replacement or maintenance of the hinged door.
