[0032] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, and the same reference numerals are used for elements that perform the same functions in FIGS. 3 to 9B. Meanwhile, in the illustration and detailed description of the drawings, detailed descriptions and illustrations of elements that are not directly related to the technical features of the present disclosure are omitted, and only the technical configurations related to the present disclosure are briefly shown or explained.

[0033] Meanwhile, in the description of the preferred embodiment of the present disclosure, the front side 50 refers to the front direction side of the door 50, the back side refers to the back direction side of the door 50, and the lateral side refers to both side-direction sides of the door 50 and it will be known that this is a general direction.

[0034] Referring to FIGS. 3 to 9B, the door 10 having finger pinch prevention function according to a preferred embodiment of the present disclosure include; a door frame 20 having a vertical frame 21 spaced apart from both sides and formed in a vertical direction, and a horizontal frame 22 coupled to the upper and lower portions of the vertical frame 21; a coupling frame 30 coupled to the inner side of the vertical frame 21 on one side of the door frame 20; a plurality of hinges 40 coupled to upper and lower portions of the back side 31 of the coupling frame 30; and a door 50 to which the other side of the hinges 40 is coupled to one lateral side 51; characterized in that the coupling frame 30 and the door 50 are coupled by the hinges 40, so that even when the door 50 is opened and closed, a corner portion of the corner contacting the coupling frame 30 does not generate a gap.

[0035] The door frame 20 is coupled to a wall and corresponds to a frame for supporting all elements, and consists of the vertical frame 21 and the horizontal frame 22 in a rectangular frame shape.

The vertical frame 21 is formed to face each other in a plate shape, and a projection portion 23 is formed in the vertical direction on the front side. That is, it is formed in a ‘’ shape so that the projection portion 23 is formed inner side to face each other. The horizontal frame 22 is coupled to the upper and lower portions of the vertical frame 21 in a plate shape. In the preferred embodiment of the present disclosure, the horizontal frame 22 is formed to be coupled to the upper and lower portions of the vertical frame 21, but can be coupled only to the upper portion.

[0036] The coupling frame 30 has a rectangular cross section and is coupled to the projection portion 23 of the vertical frame 21 of the door frame 20. At this time, it is coupled to the projection portion 23 of the vertical frame 21 on one side thereof, but is coupled to the inner side of the protrusion 23, that is, to the direction facing each other.

[0037] In the coupling frame 40, a coupling hole 34 is formed so that bolts 100 penetrate through the upper and lower portions of the lateral side 33 thereof to be coupled to the vertical frame 21 of the door frame 20, and a coupling groove 35 is formed on the upper and lower portions so that the hinge piece 41 of the hinge 40 is coupled to the back side 31 by the bolts 100.

[0038] In the preferred embodiment of the present disclosure, the coupling frame 30 is configured to be coupled to the vertical frame 21 by the bolts 100 when coupled to the vertical frame 21 of the door frame 20, but this is only an embodiment and may be coupled through various coupling means, including bolts and adhesives.

[0039] Meanwhile, the coupling frame 30 is formed such that the back side 31 is inclined from one side to the other side as shown in FIGS. 7A and 7B. Here, the inclined direction is formed such that the width in the direction of the vertical frame 21 of the door frame 20 becomes narrower than the width in the direction of the door 50. At this time, the inclination angle ‘θ’ is preferably 20°, but may be formed in various ways as required.

[0040] By forming the back side 31 of the coupling frame 30 to be inclined in this way, when the door 50 is opened, one side of the door 50 hits the back side 31 of the coupling frame 30. Therefore, there is an effect that can be prevented from being injured by a user entering and exiting the door 50 by returning to the front side by recoil.

[0041] Meanwhile, the cover frame 60 having a ‘’ shaped cross-sectional shape is coupled to the front side 32 and one lateral side 33 of the coupling frame 30. The cover frame 60 is intended to make the appearance appealing so that the bolt 100 used when the coupling frame is coupled to the vertical frame is not exposed to the outside. The lateral side 61 of the cover frame 60 has cutout portions 62 formed at positions corresponding to a plurality of hinges 40 coupled to the upper and lower portions of the coupling frame 30.

[0042] The hinges 40 have one side to be coupled to the coupling frame 30 and the other side to be coupled to the door 50 such that the door 50 is rotatable. The hinges 40 are made by including hinge pieces 41 to be bolted to the coupling groove 35, 52 formed in the coupling frame 30 and the door 50. The hinges 40 are composed of a plurality, and are coupled to the upper and lower portions of the coupling frame 30 and the door 50.

[0043] The door 50 is rotatably coupled to the hinges 40, a coupling groove 52 is formed such that the hinge piece 41 of the hinge 40 is coupled to one lateral side 51. At this time, the coupling groove 52 is formed on the upper and lower portions to correspond to the position and number of the hinges 40.

[0044] Meanwhile, the depth d.sub.1 of the coupling groove 35 of the coupling frame 30 and the depth d.sub.2 of the coupling groove 52 of the door 50 are, as shown in FIG. 6, are formed by half the thickness of the rotating shaft 42 of the hinges 40, and one-quarter of the rotating shaft 42 of the hinges positioned at the corner portion of the coupling frame 30 and the door 50 is formed to protrude to the front side. For example, if the thickness of the rotating shaft 42 of the hinges 40 is 12 mm, the depth of the coupling groove 35 of the coupling frame 30 and the depth of the coupling groove 52 of the door 50 are formed to 6 mm. In this way, forming the depth of the coupling groove 35 of the coupling frame 30 and the coupling groove 35 of the door 50 in half is to enable the door 50 to rotate smoothly without being caught during rotation.

[0045] According to the door 10 having the finger pinch prevention function according to the present disclosure as described above, there is an effect of preventing a finger jamming accident between the door frame 20 and the door 50 by making sure that there is no gap between the door frame 20 and the door 50 coupled to one side of the door frame 20 in the process of opening and closing the door 50.

[0046] Particularly, by coupling the coupling frame 30 which is coupled to one side of the door frame 20 and the door 50 through the hinges 40, even when the door is opened or closed, there is no gap in the corner portion where the door 50 and the coupling frame 30 come in contact with each other, thereby preventing a finger from being caught.

[0047] Meanwhile, the door 10 having a finger pinch prevention function according to a preferred embodiment of the present disclosure includes a cover 70 to prevent the hinges 40 from being exposed to the outside as shown in FIGS. 8A and 8B. The cover 70 is made of a soft synthetic resin material, and includes a wings portion 71 of which one side is coupled to the back side 31 of the coupling frame 30 and the other side is coupled to the lateral side 51 of the door 50, and an exposure prevention portion 72 that is formed between the wings portion 71 and prevent the hinges 40 from being exposed to the outside.

[0048] Meanwhile, when the cover 70 is coupled to the coupling frame 30 and the door 50, it is preferable not to form coupling grooves 35, 52 for coupling the hinges 40, and accordingly, the coupling frame 30 and the door 50 are formed to have a smaller cross-sectional area as much as the depth of the coupling grooves 35, 52.

[0049] When the cover 70 is coupled, the wings portion 71 is positioned on the back side 31 of the coupling frame 30 and the lateral side of the door 50, and the hinge piece 41 of the hinges 40 gets in close contact with the wings portion 71 to be coupled to the coupling frame 30 and the door 50 by the bolts 100. At this time, a gap corresponding to the thickness of the rotating shaft 42 of the hinges 40 is generated in the corner portion of the coupling frame 30 and the door 50. In order to block this, finishing frames 73 are coupled to the back side 31 of the coupling frame 30 and one lateral side 51 of the door 50 in a vertical direction.

[0050] By configuring in this way, on the front side the hinges 40 are not seen by the cover 70 and a gap is not generated at the same time, thereby preventing the fingers from being caught and the appearance being appealing, and on the back side the pinching of the fingers is prevented by the finishing frames 73 and the appearance is appealing. Furthermore, if the handle portion closes to the door frame 20 when the door 50 is closed, the door 50 is temporarily stopped by the cover 70, thereby preventing the finger from being caught between the handle portion of the door 50 and the door frame 20.

[0051] And the door 10 having a finger pinch prevention function according to a preferred embodiment of the present disclosure includes a back cover 80 to prevent the back side 31 of the coupling frame 30 from being exposed to the outside as shown in FIGS. 9A and 9B. In the back cover 80, one side thereof is coupled to one lateral side of the door 50, the other side thereof is formed to abut the inner lateral side 24 of the vertical frame 21 of the door frame 20, and a space between the inner lateral side 24 of the vertical frame of the door frame 20 and the door 50 is not exposed to the outside. At this time, in the back cover 80, one side thereof is coupled to one lateral side 51 of the door 50 using an adhesive or the like, and the other side thereof is formed to be movable when the door is opened or closed by abutting the inner lateral side 24 of the vertical frame 21 of the door frame 20.

[0052] As described above, the cover 70 is configured at the corner where the coupling frame 30 and the door 50 abut, and the back cover 80 is configured at the back side 31 such that the hinges 40 are not exposed to the outside on the front side, and the back side 31 of the coupling frame 30 is not exposed on the rear side, so that the appearance can be seen appealingly.

[0053] As described above, the door having the finger pinch prevention function according to the preferred embodiment of the present disclosure is illustrated according to the above description and drawings, but this is merely an example and those skilled in the art will understand that various changes and modifications are possible without departing from the technical idea of the present disclosure.
