Description

Finger protector for door {FINGER PROTECTOR FOR DOORS}

The present invention relates to a finger protection device for an entrance door, and more particularly, is coupled so that the longitudinal edges of each cover member are folded to each other, and only the upper and lower ends of each cover member are rotatably supported, so that each cover member is folded. It relates to a finger protection device for an entrance door in which the configuration for supporting can be simplified.

In general, a hinged door consists of a door frame and a door leaf, and is rotatably installed on the door frame by two or more hinges.

Hinges can be classified in various ways from 90 degrees to 110 degrees, 135 degrees, 165 degrees and 180 degrees according to the opening and closing angle, and when opening the door, there is a space between the door frame on which the hinge is installed and the door leaf (hereinafter referred to as the'hand pinched area '.) is formed.

In 2000, the Korea Consumer Protection Agency surveyed the gap between the 165° hinge's hand pinch area, and when the door was opened, the gap ranged from 0.5 cm to 3.5 cm, which was wide enough to pinch children's fingers as well as adults' fingers.

The problem here is that when the door is closed, the pressure is applied up to 40 tons/inch ² . There have been many cases of serious injury or even permanent damage if the door is closed with a finger or other body part inserted between the hand-clamped areas.

In this regard, U.S. Patent Publication No. 6,141,909 (registration date: November 7, 2000) discloses safety guards for door jambs installed on the door jambs. It is a protective shield designed to be attached to doors and door jambs to cover the pinch-void area and to prevent fingers or other objects from being pinched when the door is closed. The protective shield has a unique shape and can be attached to a narrow area, making it easy to install the protective shield even on a door with a push bar or panic device. The protective shield is designed for simplicity and therefore long lasting and aesthetic. It is also possible to allow a relatively large swing, for example up to 110 degrees, more preferably 180 degrees, without any damage to the protective shield itself, the door or the door hardware.

According to the above-described prior art, by blocking the hand jamming area between the door frame and the door leaf, not only the installation is simple, but also the appearance is beautiful, and safety accidents such as fingers being caught in the door gap can be prevented.

However, the above-described prior art has a problem in that the protection device is deformed toward the hand jamming area between the door frame and the door leaf, preventing the door from being closed, and the protection device is deformed into the hand jamming area, so that the hand jamming area cannot be covered.

As another prior art, Korean Patent Registration No. 10-0824370 (announcement date: 2008.04.25) discloses a multi-stage hand pinch prevention mechanism for doors. 1 (a) and 1 (b), the hand pinch prevention mechanism according to the prior art includes an outer member 100, a first intermediate member 200, a second intermediate member 300, and an inner Including member 400. Such a hand pinch prevention mechanism attaches the first attachment part 110 of the outer member to the door leaf 2 by double-sided tape or the like as shown in FIG. 1(a), and the second attachment part 410 of the inner member is double-sided tape. When the door leaf 2 is opened and closed while it is attached to the door frame 3 by the like, the door leaf 2 rotates about the hinge 1. At this time, a relative movement of the outer member 100 fixed to the door leaf 2 and the inner member 400 fixed to the door frame 3 occurs, and the arc shape of the outer member, the intermediate member, and the inner member is a hinge (1). Since it is located on a concentric circle having a center, the first and second intermediate members and the inner member located in the outer member naturally slide out and close the gap between the door leaf 2 and the door frame 3.

Therefore, by blocking the gap between the door frame and the door leaf, it was possible to exert an effect of preventing a safety accident such as a finger being caught in the door gap.

However, the multi-stage hand pinch prevention mechanism for the door of this structure includes an outer member, a first intermediate member, a second intermediate member, and an inner member in order to prevent a gap between the door frame and the door, and each of the components is By being configured to overlap, there is a problem in that assembly and maintenance are remarkably deteriorated.

. Patent Document 1: U.S. Patent Publication No. 6,141,909 (Registration Date: 2000.11.07) . Patent Document 2: Korean Patent Registration No. 10-0824370 (Announcement date: 2008.04.25)

It is an object of the present invention by rotating the upper and lower ends of each cover member for covering a gap formed between one end of the door to which the hinge is coupled and the door frame when the door is rotated around the hinge to open the doorway, It is possible to simplify the folding structure of each cover member, and to provide a finger protection device for a door in which the rotation support structure of each cover member is simplified.

In addition, the problem to be solved by the present invention is not limited to the technical problems mentioned above, and other technical problems that are not mentioned are clearly to those of ordinary skill in the technical field to which the present invention belongs from the following description. It will be understandable.

The object is, according to the present invention, to be connected to the door frame and the door leaf to cover a gap formed between the door frame when the door leaf is opened, formed to have a shorter length than the door leaf, and both sides in the width direction of the rear surface A first cover member vertically disposed so that first and second shaft coupling portions are respectively formed in the end regions so that the outside of the first shaft coupling portion is positioned on the door frame; The second cover is formed to have the same length as the first cover member and vertically disposed so that the outside of the fourth shaft coupling part is positioned on the door by forming third and fourth shaft coupling portions respectively in both end regions in the width direction of the rear surface absence; The first and second cover members are formed to have the same length as the first and second cover members, and first and second coupling portions are formed on both sides of the rear surface in the width direction, so that both ends in the width direction are located at the front side of the region where the second and third shaft coupling portions are formed. , A third cover member disposed vertically between the second cover members; And a pair of upper and lower portions of the first, second, and third cover members so as to face each other so that the first cover member is rotatably coupled to the door frame, and the second cover member is rotatable to the door leaf. And the first, second, and third cover members include a rotation connecting portion connecting the first, second, third, and fourth shaft coupling portions to be folded or unfolded at a rotation point, and the first, second ,3 When the door is opened while the cover member is folded, the first, second, and third cover members rotated and supported by the rotational connection unit are unfolded to cover a gap between the door and the door frame. It is achieved by means of a protective device.

The first, second, third, and fourth shaft coupling portions are formed of a fitting groove having an arc-shaped cross section so as to be rotatably coupled to the rotation connecting portion, and the outer side of the fitting groove is folded and unfolded by the rotation connecting portion.
