Background Art Generally, a hinged door is a type of door which has been widely used as an entrance of a building, and is made of various materials, such as glass, wood, or iron.

As shown in FIG. 1, when a hinged door 1 is pushed or pulled, the door 1 pivots on a hinge shaft 3, thus opening or closing an entrance. In order to avoid interference between a hinged side of the door 1 and a doorframe or wall 2 during the rotation of the hinged door 1, a gap 4 is provided between the hinged side of the door 1 and the doorframe or wall 2.

However, a person's fingers may be caught in the gap 4 defined between the hinged side of the door 1 and the doorframe or wall 2, so that the person may be seriously

injured. Further, external noise or dust may undesirably enter a room through the gap 4.

Disclosure of the Invention Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a safety device for hinged doors, which covers a gap between a hinged door and a doorframe or wall, using a flexible bellows part, thus preventing fingers from being accidentally caught in the gap, thereby preventing persons from being injured, and preventing noise or dust from entering a room, and accomplishing a good appearance.

In order to accomplish the above object, the present invention provides a safety device for hinged doors, capable of covering a gap between a hinged door and a doorframe. The safety device includes a bellows part attached to predetermined portions of both the hinged door and the doorframe, thus covering the gap at inner and outer sides of the hinged door. The bellows part has flexibility to allow for a change in a length thereof in response to a rotation of the hinged door.

Brief Description of the Drawings The above and other objects, features and other

advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. 1 is a perspective view to show a part of a hinged door; FIG. 2 is a view of a safety device for a hinged door, according to the first embodiment of the present invention ; FIG. 3 is a view of a safety device, according to a modification of FIG. 2; FIG. 4a is a perspective view of a safety device for the hinged door, according to the second embodiment of the present invention; and FIGS. 4b and 4c are perspective views of safety devices, according to modifications of FIG. 4a.

Best Mode for Carrying Out the Invention Reference should now be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components.

FIG. 2 is a view of a safety device for a hinged door, according to the first embodiment of the present invention, FIG. 3 is a view of a safety device, according to a modification of FIG. 2, FIG. 4a is a perspective view of a safety device for the hinged door, according to the

second embodiment of the present invention, and FIGS. 4b and 4c are perspective views of safety devices, according to modifications of FIG. 4a.

According to the first embodiment of the present invention, as shown in FIGS. 2 and 3, the safety device includes a bellows part 10 to cover a gap 5 between a hinged door 1 and a doorframe or wall 2.

The bellows part 10 used as the safety device is attached, at both end portions thereof, to inner and outer sides of the hinged door 1, respectively. As shown in FIG.

2, an intermediate portion of the bellows part 10 is constructed in a U-shape to be attached to the doorframe or wall 2 while surrounding a part of the doorframe or wall 2.

Alternatively, as shown in FIG. 3, the intermediate portion may be constructed to have a flat surface, so that the flat surface is attached to a surface of the doorframe or wall 2.

As such, the bellows part 10 is attached to both the doorframe or wall 2 and the hinged door 1, thus covering the gap 5 at the inner and outer sides of the door 1. While the hinged door 1 pivots on a hinge shaft 3, the bellows part 10 contracts and extends to allow for a change in a length thereof.

As shown in FIG. 4a, a safety device according to another embodiment of the present invention includes two bellows parts 10, and two cover parts 11 provided at opposite sides of each of the bellows parts 10. The cover

parts 11 of the two bellows parts 10 are attached to inner and outer sides of both the hinged door 1 and the doorframe or wall 2, thus covering the gap 5.

Further, as shown in FIGS. 4b and 4c, in each of safety devices according to modifications of FIG. 4a, two cover parts 11 are provided at predetermined portions of a bellows part 10. As shown in FIG. 4b, both end portions of the safety device having the bellows part 10 are attached to inner and outer sides of the hinged door 1, and an intermediate portion of the safety device is constructed in a U-shape to be attached to the doorframe or wall 2 while surrounding a part of the doorframe or wall 2.

Alternatively, as shown in FIG. 4c, the intermediate portion may be constructed to have a flat surface, so that the flat surface is attached to a surface of the doorframe or wall 2.

The safety device according to the present invention is made of synthetic resin having flexibility, such as polypropylene or polyethylene, and is attached to both the hinged door 1 and the doorframe or wall 2 using a conventional adhesive.

As such, according to the present invention, only the bellows part 10 which has flexibility to allow for a change in a length thereof in response to a rotation of the hinged door 1 is used, or the bellows part 10 is used together with the cover part 11, thus covering the gap 5 at the inner and outer sides of the door 1, therefore preventing

fingers from being caught in the gap 5, and preventing noise or dust from entering a room through the gap 5.

Further, in winter, cold wind cannot blow into the room through the gap 5, so that the room keeps warm.

Furthermore, the colorful bellows part 10 provides a good appearance.

Industrial Applicability As described above, the present invention provides a safety device for hinged doors, capable of preventing a part of a person's body, such as fingers or toes, from being accidentally caught in a gap between a hinged door and a wall or doorframe, and preventing inflow of noise or dust through the gap, and preventing cold wind from blowing into a room through the gap, and thereby keeping the room warm, and accomplishing a good appearance.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
