JPH10159431A - Gravity two-axis hinge and mount structure for door - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable opening and closure through two right angles and enable attachment to a door of fragile material by providing a gravity axis at each tip of both side pieces of a hinge body, supporting a hinge piece on the axis so as to be bendable, and imparting spring forces to the hinge body to mount an oscillating claw. SOLUTION: A hinge piece 4 on the side of a gravity axis 10a is mounted to a stud 5, while a hinge piece 6 on the side of the other axis 10b is mounted to a door 2. If the door 2 is opened, the axis 10a rotates and a hinge body 8 and the door 2 are opened at 90 degrees. A torque is imparted to the axis 10b in such a direction as to close the door 2 by the weight of the door 2 and a torque is imparted to the axis 10a so as to open the door, and hence the body 8 and the door 2 are rotated about the axis 10a without the rotation of the axis 10b. And if the body 8 and door are rotated through 90 degrees, a side piece 9a makes contact with a stopper bar 12, and thereafter only the door 2 is turned about the axis 10b. If the door is further turned through 90 degrees, the door becomes parallel with a fixed panel 11. And a claw 14 provided on the body 8 comes into contact with a stopper 13 so that a spring force is produced so as to return the door. Thus a smooth opening and closing can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravity hinge capable of opening and closing a heavy door by 180 degrees using its own weight.

[0002]

2. Description of the Related Art Grevitity hinges are hinges that can be opened and closed by utilizing the weight of the door. Depending on how the hinge is attached, when a door opened by hand closes naturally,
Conversely, a door closed by hand may open naturally, and is often used for a door of a toilet booth or the like. However, this gravity hinge cannot open and close the attached door over 180 degrees.

If the door is made of an inorganic material such as marble and is very brittle, it is not possible to attach a gravity hinge to the side end of the door. There is.

[0004]

As described above, the conventional gravity hinge has the above-mentioned problems. The problem to be solved by the present invention is these problems.
Provided is a gravity hinge which can be opened and closed to a certain degree and can be attached to a door made of a brittle material such as marble.

[0005]

SUMMARY OF THE INVENTION The hinge of the present invention is a hinge having two axes. The hinge body has a U-shaped cross section, and has a gravity axis at one end of both sides of the hinge body. It is provided so as to be pivotable. The gravity shaft is formed by a cylindrical cam as in the prior art, and can rotate by the weight of the door acting on the inclined cam. The U-shaped hinge body is provided with a claw that can be oscillated by a spring force.

[0006] By the way, the gravity hinge is attached to the inside of the panel or door and is not exposed at all on the front side.
A butterfly supported on one gravity axis is fixed to the side surface (fixed panel side) of the stud, and a butterfly supported on the other gravity shaft is fixed on the door. Then, a stopper attached to the fixed panel side and extending to the door side contacts the back surface of the door to perform positioning. Further, the stopper attached to the door side is pressed against the claw attached to the hinge body.

When the door is opened, the stud-side gravity shaft rotates and the door rotates 90 degrees to open. However, a load acts on the door-side gravity shaft in a direction to close the door. Do not rotate. When the door is opened 90 degrees, the hinge body hits the back of the panel and the movement is regulated. After that, the gravity axis on the door rotates and the door opens further 90 degrees, and the 180-degree opening as a whole opens. can get.

Conversely, when closing the door, the gravity axis on the door side must rotate and return 90 degrees, and then the gravity axis on the stud side must rotate and return 90 degrees to operate to close the door. No. The stud side gravity shaft is subjected to a torque to open due to the weight of the door, so the door side gravity shaft rotates and returns to 90 degrees and stops when it rotates, and then the stud side gravity shaft rotates. Will be. Here, the claws are attached to the hinge body so that the stud-side gravity axis does not rotate first when the door is closed.

That is, when the door is closed, or when the door is opened 90 degrees, the stopper attached to the door is engaged with the claw, but when the door is opened 180 degrees, the claw is not engaged. Cancel. Therefore, the tip of the claw is close to the stopper that is attached to the panel and extends from the panel, and the stud-side gravity axis cannot rotate. The door is rotated back by 90 degrees and the stopper is locked to the claw, whereby the claw tip is separated from the panel-side stopper.
Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

1 shows a door 2 provided with a gravity hinge 1 according to the invention. A locking device 3 is attached to the front end side of the door 2, one butterfly 4 of the above-mentioned gravity hinge 1 is fixed to a stud 5, and the other butterfly 6 is fixed to a beam 7 attached to the back of the door. I have. Therefore, door 2 can be opened and closed based on the gravity hinge, and 180
A degree opening is obtained.

FIG. 2 is a detailed view of the gravity hinge, showing a plan view. As is clear from the figure, the gravity hinge 1 has gravity axes 10a, 10b at the tips of the side pieces 9a, 9b of the U-shaped hinge body 8. The gravity hinge 1 shown in the figure is a general one-axis gravity hinge attached to each side piece 9a, 9b, and the butterfly piece 4 on the gravity axis 10a side is attached to the stud 5,
The butterfly 6 on the other gravity axis 10 b side is attached to the door 2.

FIG. 2 shows a state in which the door 2 is closed. When the door 2 is opened, the gravity shaft 10a on the stud side rotates to move the hinge body 8 and the door 2 90 degrees as shown in FIG.
Will be open every time. Due to the weight of the door 2, torque acts on the gravity shaft 10 b in a direction to close the door 2, and one of the gravity shafts 10 a acts on the door 2 in a direction to open the door 2, so that the gravity shaft 10 b rotates. Hinge body 8 around gravity axis 10a
And the door 2 rotates.

If the hinge body 8 rotates 90 degrees as shown in FIG. 3, the side piece 9a is attached to the back surface of the fixed panel 11 and comes into contact with the stopper 12 extending toward the door 2. Therefore, the hinge main body 8 cannot rotate any more, and thereafter, only the door 2 rotates about the gravity axis 10b and opens. FIG. 4 shows a case where the door 2 is further rotated 90 degrees and opened 180 degrees, and the door 2 is parallel to the fixed panel 11.

A substantially L-shaped claw 14 is attached to the hinge body 8 of the gravity hinge 1 of the present invention. The claw 1
4 can swing about a shaft 15, and a spring 16 is wound around the shaft 15, one end is fixed to a fixing pin 17 provided on the hinge body 8, and the other end is movable on a claw 14. It is fixed to the pin 18. And this claws 14
, The tip of a stopper 13 attached to the door 2 hits, and presses the claw 14. Therefore, claws 14
Is inclined, and a spring force that is trying to return to its original state is constantly acting.

If the door 2 is turned by 180 degrees to be parallel to the fixed panel 11 as shown in FIG.
The claw 14 is separated from the claw 14, and the claw 14 is returned to an original position by a spring force. If the claw 14 returns to the original position, the claw tip 19 is located near the tip of the stopper 12.

When closing the door 2 which has been opened by 180 degrees, the door 2 rotates about the gravity axis 10b. That is, even if it tries to rotate around the gravity axis 10a, the claw tip 19 hits the stopper 12, and the rotation of the hinge body 8 is prevented. Accordingly, only the door 2 rotates about the gravity axis 10b, and the hinge body 8 remains stopped. If the door 2 returns 90 degrees to the state shown in FIG.
To incline the claws. As a result, the claw tip 1
9 moves away from the stopper 12.

When the claw tip 19 is released from the stopper 12, the hinge body 8 rotates about the gravity axis 10a and the door 2 is closed as shown in FIG.
The side end of the door 2 hits the stopper 12 and is properly closed at a predetermined position. As described above, the two-axis gravity hinge of the present invention is provided with a gravity shaft at one end of both sides of a U-shaped hinge body, and the butterfly shaft is supported on the gravity shaft. Can be obtained.

[0018]

The gravity hinge of the present invention is a biaxial hinge, and can rotate the attached door by 180 degrees to open it. The direction of torque due to the weight of the doors of both gravity shafts of the gravity hinges is different, and the hinge body is provided with claws, so that the opening and closing operations are performed in order and smooth opening and closing are performed. Further, by using the gravity hinge, even if the material of the door is a brittle inorganic material such as marble, it can be attached without chipping.
