Throughout the specification, when a part is said to be "connected" to another part, this includes not only the case where it is "directly connected" but also the case where it is "indirectly connected" with another element interposed therebetween. . In addition, when a part "includes" a certain component, this means that it may further include other components, not excluding other components, unless otherwise stated, and one or more other characteristics. However, it should be understood that it does not preclude the possibility of existence or addition of numbers, steps, operations, components, parts, or combinations thereof.

First of all, to define a term for a direction, the height direction may mean a vertical direction based on FIG. 1 . That is, the height direction may refer to a rotational axis direction of the rotating unit 200 rotated by the hinge unit 300 to be described below.

As shown in FIGS. 1 to 4, the hinge 10 according to an embodiment of the present invention is connected to a body (not shown) forming a storage space and a door (not shown) that opens and closes the storage space, so that the door It may be a device that guides the rotation of

The main body may be a piece of furniture forming the storage space for storing things, such as a locker.

For example, the door is a component of furniture and may mean a door that selectively opens and closes the storage space.

Here, as an example, the hinge 10 may include a fixing part 100 connected to either the main body or the door and a rotating part 200 connected to the other one of the main body or the door.

For example, the fixing part 100 may be connected to the main body by a fastening member such as a screw, and in this case, the rotating part 200 may be connected to the door by a fastening member such as a screw.

Meanwhile, as an example, the fixing part 100 may be connected to the door by a fastening member such as a screw, and in this case, the rotating part 200 may be connected to the main body by a fastening member such as a screw.

However, for convenience of description, below, it will be assumed that the fixing part 100 is connected to the main body and the rotating part 200 is connected to the door.

For example, the rotation unit 200 may be rotated by an external force with respect to the fixing unit 100 so that the door is rotated with respect to the main body to selectively open and close the storage space.

For example, FIG. 4(a) is the position between the fixing part 100 and the rotation part 200 in the open position of the door, and FIG. 4(b) shows the position of the rotation part 200 in FIG. 4(a). It is a position where the door is moved in the direction of closing the storage space by being rotated in the direction of the closed position on the fixing part 100, and FIG. 4(c) shows that the rotating part 200 in FIG. ) may be further rotated in the direction of the closed position so that the door closes the storage space.

As a result, sequentially, FIGS. 4 (a), 4 (b), and 4 (c) may mean that the rotation part 200 is rotated from the open position to the closed position on the fixing part 100. 4 (a), 4 (b), and 4 (c) in the reverse order may mean that the rotating part 200 is rotated from the closed position to the open position on the fixing part 100. .

Here, as an example, the fixing part 100 faces the rotating part 200, and extends from the fixed fastening part 110 to which the hinge part 300 to be described below is fastened, and the fixed fastening part 110 A fixed body portion 120 connected to either the main body or the door and a fixed extension portion 130 protruding from the fixed body portion 120 and surrounded and connected to an elastic portion 410 to be described below. can

On the other hand, the rotation part 200 faces the fixed fastening part 110, and extends from the first rotation part 210 to which the hinge part 300 to be described below is fastened and the first rotation part 210, and the door It may be provided with a second rotation unit 220 that provides an area in which the fastening member is fastened so as to be fixed.

Here, as an example, the hinge 10 is hinged between the rotating part 200 and the fixed part 100 so that the rotating part 200 is rotated relative to the fixed part 100 by an external force. A branch 300 may be further included.

For example, the fixed fastening part 110 may form a hinge insertion space S1 into which the hinge part 300 is inserted, and the first rotating part 210 is also a hinge into which the hinge part 300 is inserted. An insertion space (S2) may be formed.

For example, the hinge part 300 is inserted into the hinge insertion spaces S1 and S2 to connect the fixed part 100 and the rotating part 200, and the rotating part 200 connects the fixed part 100 As a standard, it can be hinged to each other so that it rotates by external force.

Here, as an example, the hinge 10 further includes a shock absorbing part 400 for buffering the movement of the rotating part 200 when the rotating part 200 is rotated toward the closed position on the fixing part 100. can do.

For example, the shock absorber 400 may be configured to prevent the rotation unit 200 from rapidly rotating on the fixing unit 100 to prevent damage to the door by preventing the door from being opened or closed with force.

For example, the buffer unit 400 may be configured to buffer the movement of the rotation unit 200 by using an elastic force.

Hereinafter, the shock absorber 400 will be described in more detail with reference to FIGS. 1 to 4 .

For example, the shock absorber 400 may include an elastic part 410 connected to the fixing part 100 and a pressing part 420 protruding from the rotating part 200 toward the elastic part 410. can

For example, the elastic part 410 may be disposed connected to the fixing part 100, and may have an elastic material such as rubber or synthetic resin.

For example, the pressing part 420 is formed on the rotating part 200, and when the rotating part 200 is rotated in the direction of the closed position on the fixing part 100, the elastic part 410 It may be configured to buffer the movement of the rotation unit 200 by applying pressure.

For example, the pressing part 420 may be made of a material such as metal or plastic, which has less or no elasticity than the buffer part 400 .

As a result, the buffering function in which the shock absorbing part 400 buffers the movement of the rotating part 200 is disposed on the fixing part 100 while the pressing part 420 moves in conjunction with the rotating part 200. It can be implemented due to the elastic deformation of the elastic part 410 by pressing the elastic part 410.

Of course, it is obvious that the pressing part 420 is formed on the fixing part 100 and the elastic part 410 is disposed on the rotating part 200 to buffer the movement of the rotating part 200. do.

On the other hand, as an example, the elastic part 410 is connected to the fixing part 100 and forms an enclosing space S3 into which the fixing part 100 is inserted so as to surround the fixing part 100 ( 411) and a protrusion 413 protruding from the enclosing portion 411 and being pressed by the pressing portion 420 to buffer the movement of the pressing portion 420.

For example, the enclosing part 411 may form the enclosing space S3 into which the fixing part 100 is inserted so as to be detachable from the fixing part 100 .

For example, the enclosing portion 411 forms the enclosing space (S3), but one direction is open to the outside so that the fixing part 100 can be inserted into or detached from the enclosing space (S3) in one direction. The surrounding space S3 may be formed.

For example, the enclosing portion 411 may be formed in a 'c' shape.

For example, the enclosing part 411 includes a first enclosing part 411a covering the outer surface of the fixed extension part 130, a second enclosing part 411b covering the inner surface of the fixed extension part 130, and A third enclosing portion 411c covering one side of the fixed extension portion 130 may be provided.

For example, the first enclosing portion 411a, the second enclosing portion 411b, and the third enclosing portion 411c may form the enclosing space S3 into which the fixed extension part 130 is inserted. there is.

The fixed extension part 130 is inserted into the enclosing space S3 formed by the first enclosing portion 411a, the second enclosing portion 411b, and the third enclosing portion 411c, and is inserted into the enclosing portion. It may be connected to 411, or separated from the enclosing portion 411 by being separated from the enclosing space S3 by an external force.

Meanwhile, the protruding portion 413 may be formed to protrude from the enclosing portion 411 so as to come into contact with the pressing portion 420 when it is moved.

That is, when the pressing part 420 rotates on the rotating part 200, it contacts the protruding part 413, and the movement can be buffered by the elastic force of the protruding part 413.

Here, as an example, the protruding portion 413 protrudes from the enclosing portion 411 and forms an insertion space S4 into which the pressing portion 420 is inserted. The protruding body portion 413a and the protruding body portion 413a Inclined portion 413b protruding from) toward the insertion space S4 and forming a slope 4130 that allows the elastic portion 410 to move downward in the height direction by the pressure of the pressing portion 420. can be provided.

To explain this in more detail, the elastic part 410 is not fixed on the fixing part 100 by a separate fastening member such as a screw or bolt in order to maximize the ease of assembly, but the fixing extension part 130 ) is inserted into the enclosing space S3 formed by the first enclosing portion 411a, the second enclosing portion 411b, and the third enclosing portion 411c to be tightly fitted to the fixing part 100. ), the elastic part 410 may unintentionally move upward in the height direction on the fixed extension part 130 as the door is repeatedly closed and opened.

Therefore, the inclined portion 413b is formed on the insertion space S4 so that the elastic part 410 moves upward in the height direction on the fixing part 100 and moves downward in the height direction again. can

For example, the inclined portion 413b may be formed in an upper and lower beam shape on the insertion space S4.

As a result, in a state where the elastic part 410 is unintentionally moved upward in the height direction on the fixing part 100, when the pressing part 420 is moved from the open position to the closed position, the pressing part 420 may come into contact with the inclined portion 413b to press the inclined surface 4130 of the inclined portion 413b, and due to the inclined surface 4130, the elastic part 410 moves downward in the height direction. It can be moved and moved to its intended position.

At this time, the pressing part 420 can realize the shock absorption of the door due to contact with the inclined surface 4130 .

Meanwhile, the inclined portion 413b may include the slope 4130 and a horizontal surface 4131 facing the pressing portion 420 in the height direction in the closed position.

For example, the horizontal surface 4131 may be configured to face and contact the lower surface of the pressing part 420 when the pressing part 420 is in a closed position.

As a result, the horizontal surface 4131 can also realize the shock absorption of the door when the pressing part 420 is moved to the closed position and the open position.

Meanwhile, the protruding portion 413 protrudes from the protruding body portion 413a toward the insertion space S4 and may further include a hemispherical stopper 413c.

Here, the stopper 413c may be formed to be spaced apart from the inclined portion 413b in the height direction.

For example, a separation distance in the height direction between the stopper 413c and the inclined portion 413b may be smaller than a length of the pressing portion 420 in the height direction.

Therefore, when the pressing part 420 is moved from the open position to the closed position, the pressing part 420 comes into contact with at least one of the stopper 413c and/or the inclined part 413b to realize a shock absorber. It can be.

That is, when the stopper 413c and/or the inclined portion 413b rotates the pressing part 420 in the closed position toward the open position, the pressing part 420 in the open position When it is rotated in the direction of the closed position, it comes into contact with the pressing part 420 to limit the rotation of the pressing part 420, thereby implementing a shock absorber.

Meanwhile, the stopper 413c may be formed at a position overlapping the horizontal surface 4131 in the height direction.

As a result, the stopper 413c and the inclined portion 413b cooperate with each other to implement the shock absorber of the pressing portion 420 .

In addition, the stopper 413c may be separated from the second enclosing portion 411b by a predetermined distance to form a restraining space S5.

The restriction space S5 may refer to a space in which the pressing part 420 is positioned when the pressing part 420 is in a closed position.

Hereinafter, based on the technical idea described above, the buffering function will be described in more detail with reference to FIG. 4 .

As shown in FIG. 4(a), the positional relationship between the rotating part 200 and the fixing part 100 may mean an open position where the door does not close the storage space.

At this time, the pressing part 420 may be in a state not in contact with the protruding part 413 .

Here, when the rotating part 200 is rotated toward the closed position on the fixing part 100 by an external force, as shown in FIG. 4(b), the pressing part 420 moves into the insertion space S4. While being inserted, it may come into contact with the protruding portion 413 .

Here, when the elastic part 410 is unintentionally moved upward in the height direction on the fixing part 100, the pressing part 420 is applied to the inclined surface 4130 of the inclined part 413b. It can be moved in the direction of the closed position while pressing, and as a result, the elastic part 410 can be moved downward on the fixing part 100 in the height direction and moved to the intended position.

Here, when the rotating part 200 is further rotated toward the closed position on the fixing part 100 by an external force, as shown in FIG. 4(c), the pressing part 420 closes the stopper 413c. While pressurizing, the position may be changed to the restraining space (S5).

At this time, the pressing part 420 may be buffered while coming into contact with the stopper 413c and/or the horizontal surface 4131 of the inclined part 413b.

In the reverse order, even when the rotating part 200 is rotated toward the open position on the fixing part 100 from the closed position where the door closes the storage space, the pressing part 420 moves to the restraining space S5. Buffering may be implemented as the stopper 413c and/or the inclined portion 413b come into contact with the horizontal surface 4131 of the stopper 413c and/or the inclined portion 413b.

Furniture according to another embodiment of the present invention may include the hinge 10, a main body forming a storage space, and a door that is rotated by the hinge to open and close the storage space.

That is, the hinge 10 is connected to the body and the door, respectively, so that the door can selectively open and close the storage space of the body.

As an example, the furniture may be a locker, but is not limited thereto.

In the above, the configuration and characteristics of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and various changes or modifications can be made within the spirit and scope of the present invention. It will be apparent to those skilled in the art, and therefore such changes or modifications are intended to fall within the scope of the appended claims.
