In the following, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the embodiments are for a clear understanding of the present invention, and the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so if they are not necessary for the understanding of the invention, they will not be described repeatedly, and well-known components will be briefly described or omitted, but the present invention It should not be understood as being excluded from the embodiment of.

1 shows an embodiment of a door to prevent pinching of both hands according to the present invention.

Referring to Figure 1, both the hand pinch prevention door is a protection member 11 coupled to one side of the door body (D); A contact induction member 12 coupled to the door frame F to induce rotation of the protection member 11; An opening/closing adjustment hinge 13 for adjusting an opening/closing speed of the door body D while coupling one of the protection members 11 to the door frame F; And a rotation hinge 14 that couples the other side of the protection member 11 to the door frame frame F so that the door body D rotates.

The door body (D) may have a structure in which the door body (D) is opened and closed while being rotated with respect to one edge while being in the shape of a square plate as a whole, but may be opened and closed in a sliding manner through appropriate structural changes. The door body (D) may open and close the door frame frame (F) serving as an entrance passage, and the door frame frame (F) may have a square or similar shape in which a person can enter. When the door body (D) is rotated for opening and closing, a jamming area (JP) may be formed between the vertical members of the door body (D) and the door frame frame (F) facing each other, and the door according to the present invention is jammed as such. It has a structure that prevents human body parts such as fingers or pets such as dogs from being caught in the prevention area JP. The protective member 12 may have a semi-cylinder shape as a whole, and may be coupled to one side edge of the door body D. For example, the protective member 11 may be coupled to one side of the door body D in a shape surrounding the side surfaces of the door body D at both edges of the half-cylindrical open portion. In addition, the circular circumferential surface of the protection member 12 may protrude outside one side of the door body D. The contact inducing member 12 may be coupled to the vertical surface of the door frame frame F facing the protective member 11. The contact inducing member 12 may have a curved shape having a large radius of curvature as a whole or a curved shape convex in the direction of the protection member 11. The protective member 11 may extend linearly from the lower end to the upper end of one side of the door body D, and the contact inducing member 12 may also have the same or similar length as the protective member 11. It may be extended to reach the upper end from the lower end of one side of the door frame (F). The protective member 11 and the contact inducing member 12 may form a boundary region or a contact region extending in a vertical direction. For opening and closing, the door body D may be rotated, and the protection member 11 coupled to the door body D may be rotated together with the rotation of the door body D. The contact area or boundary area between the protection member 11 and the contact induction member 12 may be a rotation axis of the door body D. As the circumferential surface of the protective member 11 becomes a curved surface, a gap between the protective member 11 and the contact inducing member 12 is rotated by contacting the circumferential surface of the curved contact inducing member 12 having a large radius of curvature. It can be prevented from occurring. As a result, the pinched region JP is not formed.

An opening/closing adjustment hinge 13 may be installed at a lower portion of the door frame F, and a coupling portion coupled to the protection member 11 may be formed on the opening/closing adjustment hinge 13. The lower portion of the protective member 11 may be rotatably coupled to the coupling portion. The opening/closing adjustment hinge 13 may be installed in a form accommodated in the protection member 11, and may have a hydraulic operation structure operated by hydraulic pressure, but is not limited thereto. The opening/closing adjustment hinge 13 may have a function of adjusting or limiting the rotational speed of the door body D according to external pressure. For example, while the door body D is gradually closed, the opening/closing control hinge 13 may be rotated at a constant speed according to a pressure of a predetermined size. In contrast, when a large pressure is applied to the door body (D) for a short period of time and the opening/closing control hinge (13) needs to rotate at a high speed, a damper function is operated inside the opening/closing control hinge (13) to control the opening/closing hinge (13). Speed of rotation may be limited. The rotation speed of the door body D may be limited or the rotation angle may be limited by the rotation speed control function or the rotation speed limit function of the opening/closing control hinge 13, whereby the door frame frame F and the door body The pinch of the pinched region JP formed between one side surface of (D) can be prevented. The opening/closing control hinge 13 may be operated in a manner similar to, for example, an ABS brake, so that the rotational speed of the door body D is limited when a large pressure or a large moment is applied. The opening/closing adjustment hinge 13 may limit the rotational speed of the door body D in various ways, and is not limited to the presented embodiment.

The door body (D) can be rotated based on the opening and closing adjustment hinge (13) and the rotation hinge (14), and the opening and closing adjustment hinge (13) and the rotation hinge (14) are respectively lower of one side of the door body (D). And can be combined on the upper side. One portion of the rotation hinge 14 is fixed to the door frame frame F, and the door body D may be coupled to a portion exposed in the direction of the door frame F from the door frame frame F. One part of the rotation hinge 14 may be fixed to the door frame frame F, and the door body D may be rotatably coupled to the rotation hinge 14. The rotation hinge 14 may be accommodated in the protection member 11, thereby preventing exposure to the outside like the opening/closing adjustment hinge 13. In this way, the opening/closing adjustment hinge 13 and the rotation hinge 14 are installed at one end of the upper member and the lower member of the door frame frame F facing each other, and the upper and lower portions of one side of the door body D It may be coupled to each of the opening and closing adjustment hinge 13 and the rotation hinge so as to be rotatable. Accordingly, a door of a rotational opening/closing method is installed without using parts such as hinges. Accordingly, the installation of the door body D is simplified while preventing a gap in the vertical direction of which the width changes between the door body D and the door frame frame F from being formed. The door body (D) may have various opening and closing structures and is not limited to the presented embodiment.
