Abstract

The objective of the present invention is to provide a stopper device of a door hinge, which fixes a door in order to maintain stability against strong wind by maximizing the attached surface between a rotating plate of a hinge and a magnet and increasing the fixing force of the door. For the above-mentioned purpose, the stopper device includes a fixing plate fixed to a door frame; and a hinge having the rotating plate fixing a door to be rotated around a hinge axis against the fixing plate. A hinge holder is additionally installed in the hinge unit of the hinge. The magnet is fixed to the hinge holder, so when the door is opened, the metal magnetic rotating plate, which rotates along with the door, adheres to the magnet equipped in the hinge holder and fixes the open position of the door by magnetic force. The stopper device of a door hinge includes a first curved surface, which is fitted and attached to the cylindrical curvature of the hinge unit in the edge of one side opposite to the hinge unit of the magnet; and a second curved surface, which is fitted and attached to the cylindrical curvature of the hinge unit and the curvature of the corner connecting the rotating plate in a connection part between the first curved surface and the front adhesive surface of the magnet.

Description

[0001] The present invention relates to a stopper device for a door hinge,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hinge for opening and closing a door, and more particularly to a stopper device used in a door hinge to prevent sudden closing of a door by wind or the like in a state that the door is opened, To a structure improvement of a magnet member used in a stopper device.

In order to open or close the door of a wooden door or a metal material, a hinge is indispensably installed on the door frame.

Generally, the structure of the hinge comprises a fixed plate fixed to the door frame, a rotary plate fixed to the door, and a hinge shaft connecting the rotary plate and the fixed plate. When the door is pushed or pulled open, the door is fixed The rotating disk is rotated and opened or closed.

However, when the wind is blown or the door is accidentally touched while the door is opened to some extent, it is inconvenient that the door should be turned and closed and then opened again. Further, when the door is closed suddenly by a strong wind The door stopper is installed so that the door that has been conventionally opened is not closed artificially in order to solve such a problem.

There are various kinds of door stoppers. Generally, a method of digging a groove on a concrete floor surface and attaching a latch to the groove is a problem in construction and an operation inconvenience of fixing and releasing the door. In the method of using the wedge piece, the wedge piece was pushed into the gap between the bottom surface and the bottom of the door, and when the door was closed, the wedge had to be pulled out by using the hand.

In view of these problems, Korean Utility Model Laid Open Publication No. 2020090009212 (titled design: hinged holder), FIGS. 1 and 2 (FIG. 1 is a view showing a door hinge and a hinge holder separated from each other, And a rotary plate 14 to which the door is fixed so as to pivot about the hinge axis 12 with respect to the fixed plate 10 as shown in Fig. A separate hinge holder 18 is attached to the hinge portion 20 of the hinge 16 and the magnet 22 is fixed to the hinge holder 18 so that the door is fixed to the hinge holder 18 as shown in FIG. The rotating plate 14 (see the one-dot chain line in FIG. 2) of the metal magnetic body rotating together with the door when it is rotated and opened in the direction of the arrow is supported by the attracting surface 24 of the magnet 22 provided in the hinge holder 18 ), And is fixed by the magnetic force, Or it is configured to not close a door attached to the magnet 22 through the above rotating plate 16 does not apply a large force artificial maintain a fixed state in an open position.

However, the adsorption method using the magnet is advantageous in that it is easy to operate the door by opening and closing the door and can be installed without incurring a large cost. However, since the fixing element of the door depends on the attraction force of the magnet 22, For this purpose, it is necessary to maintain close contact between the magnet and the metal object to be attached. However, as shown in Fig. 2, usually, since the magnet is inferior in moldability, a simple shape such as a rectangle is often taken. The tip end attracting surface 24 of the magnet 22 is in close contact with only the rotating plate 16 and only between the cylindrical engaging portion 26 and the magnet 22 integrally formed therewith, Since the double curved shape of the cylindrical coupling portion 26 (due to the small curved surface of the corner portion bent outward from the circular arc surface of the cylinder) does not contact the magnet 22, There is a problem that the magnet 22 and the rotary plate 16 can not be brought into close contact with each other due to the interference of the corner portion of the magnet with respect to the double curved surface portion so that the fixing force of the magnet is lowered have.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a door hinge stopper device capable of maximizing a close contact surface between a rotary plate and a magnet of a hinge to increase the fixing force of the door, The purpose of the proposal is.

In order to attain the above object, the present invention provides a hinge comprising a fixed plate fixed to a door frame and a rotary plate having a door fixed to the fixed plate to rotate about a center of the hinge axis, wherein a hinge holder Which is a metal magnetic body rotating together with the door when the door is opened by fixing the magnet to the hinge holder, is attracted to a magnet provided on the hinge holder and fixed to the door by the magnetic force, A hinge stopper device according to claim 1, wherein the hinge stopper device has a first curved surface in which one side edge portion of the magnet facing the hinge portion coincides with the cylindrical curved surface of the hinge portion, And the connecting portion has a second curved surface which closely coincides with the curved surface of the hinge portion and the corner curved surface connecting the rotating plate That is configured to be characterized.

According to the present invention as described above, since the attraction surface of the magnet generating the attraction force (magnetic force) for fixing the door is formed along the contour of the rotating plate of the hinge and the cylindrical curved surface of the hinge, So that the fixing force of the door is greatly increased. As a result, there is no fear that the door will be damaged due to the fixed state of the door even in strong winds, and there is no need to frequently open the door .

Figures 1 and 2 are diagrams illustrating the prior art.
