Abstract

PURPOSE: A hinge is provided to protect fingers of a person when a door is closed by closing the door only when power is applied to the door. CONSTITUTION: A hinge(100) comprises a first plate(10), a hinge(20), a second plate(30), a housing member(40), and a leaf spring(50). The second plate is coupled to the first plate through the hinge and is moved relatively to the first plate. The housing member is coupled to the surface of the first plate. The leaf spring is coupled to the housing member and has a convex bent. When the bent of the leaf spring touches the second plate, the bent is moved downward and is restored back to the original state thereof when the bent is separated from the second plate.

Description

Hinge {Hinge}

The present invention relates to a hinge, and more particularly to a hinge that can protect the human finger when closing the door.

In general, the hinge is used for various purposes, but it is especially used to open and close the door in combination with the door.

By the way, the conventional hinge supports the door so as to open and close freely, but the door or door frame is damaged or the noise is severely generated because the free end of the door strongly collides with another door frame due to the strong closing of the door or by the wind. There was a problem.

In addition, in this case, a serious safety accident occurred when a part of the body such as a finger is located between the door and the door frame, and in particular, when the children open and close the door, this risk doubles.

The present invention has been proposed to solve the above-mentioned problems, the object is that the resistance force of the spring when the door is closed, the door is not immediately closed can be closed only when a certain force is applied to close the human body when closing the door It is possible to prevent the human body from being damaged by pinching the fingers of the human body. It has a simple structure and its production cost is low, and its life can be long by only replacing the leaf spring. The purpose is to provide a hinge that can reduce the cost and reduce the noise generated when closing the door.

Hinge according to the present invention for achieving the above object, in the hinge comprising a first plate, and a second plate coupled to the first plate and the hinge relative to the first plate, It is coupled to the receiving member and the receiving member coupled to the surface of the first plate, and has a bent convexly upwards upward, when the bent portion and the second plate is in contact, the bent portion is moved downwards and the contact is released again The bent portion is characterized in that it comprises a leaf spring having a restoring force restored to its original state.

In addition, the receiving member of the hinge according to the present invention is coupled to the surface of the first plate, the bottom plate portion having a flat plate shape, the first protrusion plate protruding from one end of the bottom plate portion, and the bottom plate A second protrusion plate protruding from the other end of the portion, a first parallel plate extending from the first protrusion plate, bent in a direction parallel to the bottom plate portion, and bent from the second protrusion plate; And a second parallel plate positioned in a direction parallel to the bottom plate portion, and one end of the leaf spring is inserted into a space between the bottom plate portion and the first protrusion plate and the first parallel plate, and The end of the side is characterized in that it is inserted into the space between the bottom plate and the second projection plate and the second parallel plate.

According to the hinge according to the present invention, the resistance force of the spring when closing the door can be closed only by applying a certain force to the door is not immediately closed, so that the body can be pinched when closing the door to prevent damage to the human body It has a simple structure and its production cost is low, and by replacing only the leaf spring, its service life can be long, and its structure that can be attached to an existing hinge can reduce its installation cost. There is an effect that can reduce the noise generated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.

Hereinafter, a hinge according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 show a hinge according to an embodiment of the present invention, Figure 1 is a perspective view of a hinge according to an embodiment of the present invention, Figure 2 is a receiving member and the leaf spring of the hinge shown in FIG. 3 and 4 are views for explaining the state of use of the hinge shown in Figure 1, Figures 5 and 6 are respectively a front view for explaining the state of use of the hinge shown in FIG. .

As shown in the figure, the hinge 100 according to an embodiment of the present invention is the first plate 10, the hinge 20, the second plate 30, the receiving member 40, the plate The spring 50 is included.

The first plate 10 has a flat plate shape and is coupled to the door, for example.

The second plate 30 is coupled by the first plate 10 and the hinge 20 to be rotated relative to the first plate 10, and has a flat plate shape, for example, in a door frame. Combined.

Since the first plate 10, the second plate 30 and the hinge 20 is a commonly seen product, further detailed description thereof will be omitted.

The receiving member 40 is coupled to the surface of the first plate 10.

The leaf spring 50 is coupled to the receiving member 40, and has a curved portion 52 that is convexly raised upward, and the curved portion 52 is in contact with the curved portion 52 and the second plate 30. ) Is moved downward and the contact is released to have the restoring force to restore the bent portion 52 to its original state.

The receiving member 40 will be described in more detail.

The receiving member 40 includes a bottom plate portion 41, a first protrusion plate 42, a second protrusion plate 43, a first parallel plate 44, and a second parallel plate 45. do.

The bottom plate portion 41 is coupled to the surface of the first plate 10, and has a flat plate shape.

The first protrusion plate 42 protrudes from one end of the bottom plate portion 41.

The second protrusion plate 43 protrudes from the other end of the bottom plate portion 41.

The first parallel plate 44 is bent and extended from the first protrusion plate 42 and is positioned in a direction parallel to the bottom plate portion 41.

The second parallel plate 45 is bent and extended from the second protrusion plate 43 and is positioned in a direction parallel to the bottom plate portion 41.

One end of the leaf spring 50 is inserted into a space between the bottom plate part 41, the first protrusion plate 42, and the first parallel plate 44. It is inserted into the space between the bottom plate portion 41, the second protrusion plate 43 and the second parallel plate 45.

Hinge 100 according to an embodiment of the present invention having the configuration as described above is as follows.

First, when the user closes the door, as shown in FIG. 3, the bent portion 52 of the leaf spring 50 and the second plate 30 come into contact immediately before the door is closed.

Therefore, the door is prevented from being closed immediately due to the contact frictional resistance between the bent portion 52 and the second plate 30, thereby preventing accidental human accidents such as pinching the human body.

The front view which showed the contact relationship of the said 1st board 10, the 2nd board 30, and the said leaf spring 50 in this state is shown in FIG.

Subsequently, when the user closes the door while continuously applying force, the door is closed while forming the elastic deformation in which the curved portion 52 of the leaf spring 50 contracts downward.

Subsequently, when the user opens the door, the bent portion 52 is restored again to return to the original state.
