DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a hinge used for opening and closing a door.

[0002]

2. Description of the Related Art In hinges conventionally used for opening and closing doors, the angle of opening and closing of a connected object such as a door is 180 degrees (2 degrees).
There was only a hinge at right angles.

[0003] However, in the case of hinges in which the opening / closing angle of a connected object such as a door is only 180 degrees (two right angles), 90% is required.
Despite the fact that opening and closing at a degree is sufficient, there is a drawback that if it is unnecessarily rotated to 90 degrees or more, it will be extremely obstructive.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hinge which can be reliably stopped at an opening / closing angle of a connected object such as a door which is hinged at 90 degrees (right angle). is there.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a back surface of a flat plate having a through hole at one end thereof having a through hole through which a connecting shaft can be inserted, and having a plurality of through holes. In addition, a movable member to which a stop member in which a joint portion, an inclined portion, and an abutment portion are formed to be bent is fixed, and a fitting portion for fitting a bearing portion of the movable member to one end and a connection shaft can be inserted into one end. A vertically long fixed-side member provided with a bearing portion having an insertion hole; and a through-hole of the bearing portion of the movable-side member and an insertion hole of the bearing portion of the fixed-side member, and the movable-side member and the fixed The hinge is configured to include a connecting shaft that rotatably connects the side member and the fixed side member has a rotation range of 90 degrees.

[0006]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a front view of the hinge of the present invention, FIG. 2 is a plan view of the hinge of the present invention, and FIG. 3 is a rear view of the hinge of the present invention.

As shown in FIGS. 1 and 2, the hinge 1 according to the present invention is bent and has a joint 2e, an inclined portion 2g, and an abutting portion 2.
The movable side member 2 includes a horizontally long flat plate 2b having a stop member 2d which is formed and bent and fixed to the back surface, and a vertically long fixed side rotatably attached to the movable side member 2. It comprises a member 3 and a connecting shaft 4 for rotatably connecting the movable side member 2 and the fixed side member 3.

That is, in the hinge 1 of the present invention, as shown in FIG. 1, a plurality of through holes 2a, 2a, 2a for inserting a set screw, a set bolt and the like are formed in the movable member 2. . One end of the movable side member 2 has a bearing 2c, 2c
Are protrudingly provided at two locations above and below.

The fixed side member 3 is formed in a vertically long rectangular shape, and fitting portions 3e, 3e into which the bearing portions 2c, 2c of the movable side member 2 can be inserted at one end are formed at two upper and lower positions. As shown in FIG. 10, the mounting plate 3b is fixed to the fixing member 5a by bolts 6a, and includes an impact plate 3c for relieving an impact when the abutting portion 2f collides.

FIG. 4 is a plan view of the movable member, FIG. 5 is a right side view of the movable member, FIG. 6 is a front view of the fixed member, FIG. 7 is a plan view of the fixed member, and FIG. Left side view of FIG. 9
Is a front view of the connecting shaft. Hereinafter, components of the hinge 1 according to the present invention will be described.

As shown in FIGS. 4 and 5, the movable side member 2 is a horizontally long flat plate 2 having shaft bearings 2c, 2c having one end formed with an insertion hole through which a connecting shaft can be inserted.
b and a stop member 2d which is bent to form a joint 2e and an abutment 2f and is fixed to the back surface of the movable member 2.

As shown in FIGS. 6, 7 and 8, the fixed member 3 is provided with a plurality of through holes 3a, 3a, and is projected from the movable member 2. Fitting part 3e, into which the bearing parts 2c, 2c can fit.
3e is formed.

As shown in FIG. 7, the fixed member 3 comprises a mounting plate 3b and a buffer plate 3c fixed to one side of the mounting plate 3b, and one end of the mounting plate 3b has a connecting shaft. 4 is provided with a bearing portion 3d in which an insertion hole through which the hole 4 can be inserted is formed.

The connecting shaft 4 shown in FIG. 9 has a flange 4a formed on the head. With the connecting shaft 4, the movable member 2 can be rotatably attached to the fixed member 3. That is, as shown in FIG. 1, in a state where the bearings 2 c, 2 c protruding from one end of the movable member 2 are fitted to the fitting portions 3 e, 3 e formed on the fixed member 3, the connecting shaft is 4 is inserted so as to be rotatable.

FIG. 10 is a plan view showing a state where an object to be connected such as a door is attached using the hinge of the present invention. FIG.
As shown in FIG. 0, an object 5 such as a door is fixed to the movable member 2 with bolts and nuts 6 and 6, and the fixed member 3 is fixed to a fixing member 5a such as a wall or a pillar with bolts 6a.

As shown in FIG. 10, when the movable member 2 to which the member 5 to be connected such as a door is fixed is turned in the direction of arrow a, the stop member 2 fixed to the rear surface of the flat plate 2b has an impact. When the joint portion 2f abuts on the fixed member 3, it cannot rotate any more, the rotation range of the fixed member 3 is 90 degrees, and it stops at a right angle to the fixed member 5a.

That is, the movable member 2 to which the object 5 is fixed
Is an abutment portion 2f of a stop member 2d on the back surface of the movable side member 2.
When the fixed-side member 3 abuts against the surface of the movable member 2, it cannot rotate any more, and stops at a position where the flat plate 2b of the movable-side member 2 and the fixed-side member 3 are at a right angle.

[0018]

The present invention has the following effects because it has the above-described configuration. First, the angle of opening and closing of a connected object such as a door can always be stopped at 90 degrees (right angle).

Second, since the hinge structure according to the present invention is extremely simple, the manufacturing cost of the hinge is extremely low.
