BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a door impact reduction device according to an exemplary embodiment; FIG. Here, a state in which the door is viewed from above is shown.

Referring to FIG. 1, a door impact reducing apparatus 100 includes a conductive member 102 mounted on a door 10 and a structure 50 (for example, an indoor wall or furniture, etc.) (Not shown). Here, the door 10 may be a door for a person to enter and exit, or a door for opening and closing a space for storing articles.

Here, one end of the door 10 may be rotatable about an axis in the longitudinal direction of the one end of the door 10 (the direction of the paper in FIG. 1). At this time, one end of the door 10 may be hinged to the structure 50 through the hinge 60. Then, the door 10 is opened and closed while rotating around the hinge 60.

The conductive member 102 may be mounted on the inner surface of the door 10 (i.e., the surface located in the direction in which the door 10 is closed). The conductive member 102 may protrude from the inner surface of the door 10. The conductive member 102 may be provided at the upper end of the door 10. [ The conductive member 102 is placed on the side of the door 10 in the region adjacent to the other end (that is, the side opposite to the side where the hinge 60 is formed) of the door 10 It can be mounted on the inner surface.

The conductive member 102 may be provided with a curvature corresponding to the curvature of the turning radius of the door 10. The conductive member 102 may be made of a metal such as copper or aluminum. The conductive member 102 may be, for example, in the form of a rod, but the shape thereof is not limited thereto.

The magnetic member 104 may be provided in the structure 50 where the door 10 is closed. Specifically, when the door 10 is closed in the structure 50, the magnetic member 104 may be provided in a region corresponding to the other edge region of the inner surface of the door 10. [

When the door 10 is closed inside the magnetic member 104, a space for inserting the conductive member 102 may be provided. When the door 10 is closed by an external force, an eddy current is generated between the conductive member 102 and the magnetic member 104 due to the electromagnetic induction phenomenon while the conductive member 102 is inserted into the space inside the magnetic member 104 . Since the closing speed of the door 10 is reduced by the eddy current, the impact due to the closing of the door 10 can be reduced.

FIG. 2 is an enlarged view of a door impact reducing device in a case where the door is closed in an exemplary embodiment; FIG.

Referring to FIG. 2, a receiving portion 111 having a space into which the conductive member 102 is inserted is formed inside the magnetic member 104. The magnetic member 104 may be of a columnar shape (e.g., a cylinder or a square column) having an empty center, but is not limited thereto. For example, the magnetic member 104 may be composed of two separate magnetic members with the receiving portion 111 sandwiched therebetween.

The diameter of the receiving portion 111 may be set to be larger than the width (or thickness) of the conductive member 102. That is, when the conductive member 102 is inserted into the receiving portion 111, the conductive member 102 and the magnetic member 104 may be spaced apart from each other by a predetermined distance. The receiving portion 111 may be provided in a shape corresponding to the conductive member 102. That is, the accommodating portion 111 may be provided with a curvature corresponding to the curvature of the conductive member 102. Likewise, the magnetic member 104 may also be provided with a curvature corresponding to the curvature of the conductive member 102.

The door impact reducing apparatus 100 may further include a stopper 106. When the door 10 is closed by an external force, the closing speed of the door 10 is reduced due to the eddy current, The door 10 is moved in the opposite direction due to the recoil, so that the door 10 can not be closed properly. Accordingly, the door 10 can be fixed through the stopper 106. [ The stopper portion 106 may include a stopper groove 111, a stopper projection 113, an elastic member 115, and an elastic member receiving groove 117.

The stopper groove 111 may be formed in the conductive member 102. The stopper groove 111 may be formed at the end portion of the conductive member 102, for example. The stopper groove 111 is formed in a concave spherical shape so that the stopper protrusion 113 can be easily inserted or removed when the conductive member 102 is pulled into and out of the receiving portion 111 Lt; / RTI >

The stopper protrusion 113 may be provided on the magnetic member 104. The stopper protrusion 113 may be inserted into the stopper groove 111 to fix the conductive member 102 when the conductive member 102 is pulled in. The stopper protrusion 113 is released from the stopper groove 111 during the pulling-out operation of the conductive member 102. [

The upper end of the stopper protrusion 113 may have a shape corresponding to the stopper groove 111. That is, the upper end of the stopper protrusion 113 may have a convex spherical shape corresponding to the concave spherical surface of the stopper groove 111. The lower end of the stopper projection 113 may be formed with a latching protrusion 113a so as not to be separated from the elastic member receiving groove 117. [

The elastic member 115 serves to provide an elastic force so that the stopper projection 113 can move up and down. The elastic member 115 can be received in the elastic member receiving groove 117 provided in the magnetic member 104. [ The elastic member 115 is positioned at the lower portion of the stopper projection 113 in the elastic member receiving groove 117.

On the other hand, an inclined portion 102a may be provided at the end of the conductive member 102. [ That is, the inclined portion 102a may be inclined downward so that the conductive member 102 does not catch on the stopper protrusion 113 during the pulling-in operation of the conductive member 102 and naturally rides over the stopper protrusion 113. [

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
