Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hinge device used for attaching, for example, a door to a doorway frame.

[Conventional technology]

As shown in FIG. 3, at an entrance such as an entrance in a house, a mounting frame F is installed on a wall W, and a door is swingably attached to this mounting frame F via a hinge device 1B. There is. In this case, hinge mounting! B is 2 as shown in Figure 4.
It consists of plate hinges PA, PB and a pin S that engages these hinges PA, PB. More specifically, each hinge PA, PR has uneven engaging portions KA, KB formed on their abutting sides, respectively, and these engaging portions KA, KB are recessed portions KA, KB, respectively. , K.B.
and A2. in these recesses. The convex portions KA1 and KB1 that enter into the KB are configured to be combined with each other.

Then, each convex portion KA1. KB1 is formed in a cylindrical shape, and each cylindrical convex part KA□, KB of both hinges PA, PB
It has a structure in which a pin S passes straight through l. Therefore, for example, when the hinge PB is fixed to the mounting frame F with wood screws N, the hinge PA can rotate around the pin S, and the hinge PA is attached to the door side with the wood screws N. It is fixed in place to maintain the function of the door.

By the way, in a normal house, there is almost no need to remove the door from the mounting frame.

Temporary doors can be installed at the entrances and exits of buildings under construction or temporary offices, and if they become a hindrance to work, they can be removed and reinstalled as necessary. be. In such cases, conventionally, the hinge device has been removed from or attached to the mounting frame each time.

[Problem to be solved by the invention]

However, the work of removing the hinge device from the mounting frame and attaching it to the mounting frame by returning or screwing in the wood screws is very time-consuming and troublesome. In addition, not only temporary doors but also regular doors, for example, when moving and moving large items, it may be much easier to remove the door. The work of removing the hinge device from the mounting frame and attaching it to the mounting frame not only requires time and effort as described above, but also becomes a very difficult work if the door is heavy.

The present invention has been made in an attempt to provide a hinge device that can be relatively easily attached to and detached from a mounting frame, which is a time-consuming and difficult task.

[Means to solve the problem]

The hinge device according to the present invention has one of a pair of hinges formed into a cylindrical shape, a pin attached to the other hinge, and the pin engaged with a convex engaging portion of one of the hinges. A notch is formed in the mating part, the part is formed into a plate shape, and one hinge is connected to the other hinge through the slit-like opening of one hinge to the part where the notch is formed in the pin of the other hinge. The gist is that the device is configured to be engaged by being removably inserted.

Also, attach the pin to the other hinge so that it can rotate freely.

It is also possible to provide a lever extending perpendicularly to the axis of the pin at one end of the pin, and a fixing means for fixing the lever at a predetermined swinging position.

[For production]

In the hinge device having the above configuration, the pin attached to the other hinge passes through the opening of the convex engaging portion of one hinge, and the corresponding portion of the pin of the other hinge passes through the notch surface of the other hinge. By removably fitting the parts along the line, they are removably engaged with each other. By setting the direction of the notch of the pin in a direction different from the normal direction when using the hinge device, the notch also functions as a part of the pin shaft, and one hinge is connected to the pin of the other hinge. There is no such thing as being left out.

Further, when a pin is rotatably attached to the other hinge, a lever is extended from one end of the pin, and the lever is fixed at a predetermined swinging position by a fixing means,
By fixing the lever in the emergency direction, one hinge is reliably prevented from being pulled out from the pin, and the rotational movement of one hinge is performed more smoothly. When the hinge device is removed, the lever is opened and the pin is rotated so that the direction of the notch matches the direction in which the pin is removed.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be explained with reference to FIGS. 1 and 2.
This will be explained with reference to the figures.

FIG. 1 is a perspective view showing a pair of hinges 1 and 2 separated and disassembled, and the hinge l has a convex engaging portion IK of the concave and convex engaging portions formed in a cylindrical shape, In the illustrated example in which the pin 3 is attached, three convex engaging portions IK are provided.

A pin 3 is rotatably held at three locations. By the way, this pin 3 has a circular cross section as shown in FIG. Notch 3
S is formed. This notch 3S is formed by chamfering from both sides, and its thickness t is set to be smaller than the diameter of the pin 3. However, this notch 3
S also functions as a pin shaft.

On the other hand, unlike the case of the hinge 1, the convex engaging portion 2F of another hinge 2 is formed in a cylindrical shape having a slit-like opening 2T on the rear side. The opening dimension T of the opening 2T is the pin 3
The relationship is set such that T>t for the notch thickness t.

Therefore, when the pin 3 is currently held in the state shown in the drawing on the hinge 1, the notch direction H of the pin 3 is in the vertical direction of the drawing, and therefore, the hinge 2 can be erected from the state shown in the drawing to the vertical state to engage the convex shape. By aligning the openings 2T of the joints 2F in the vertical direction, the hinge 2 can be released from the engagement with the hinge 1. In this manner, as long as the notch direction of the pin 3 and the opening direction of the convex engaging portion 2F of the hinge 2 are not matched, the pin 3 functions as a pin shaft. In this case, the notch 3S also
Since the portion having the thickness t is an arcuate surface, the hinge 2 can rotate smoothly.

Further, in this hinge device, a lever 4 is provided at one end of the pin 3 and extends in a direction perpendicular to the axis. This lever 4 is integral with the pin 3, and the pin 3 can be rotated by the swinging action of the lever 4. Therefore, the direction (position W) in which the hinge 2 is separated from the hinge 1 can be adjusted. On the other hand, the hinge 2 is provided with a stopper 5. The outer end of the stopper 5 is bent upward, which extends above the lever 4 and
This is to fix the movement of. Also, this stopper 5
A guide hole 5H is formed in the guide hole 5H.
A guide pin 6 implanted in the hinge 2 is inserted,
The stopper 5 is movable in the direction of the arrow. Furthermore, a spring 7 is attached to the stopper 5, and the stopper 5 is always urged outward. Therefore, when the stopper 5 is displaced in the opposite direction against the elasticity of the spring 7,
The lever 4 becomes free and allows the pin 3 to rotate.

That is, when both hinges 1.2 are to be disengaged, the stopper 5 is displaced to allow the lever 4 to move freely.

IH and 2H in the figure are holes drilled in both hinges 1 and 2, respectively. By inserting wood screws into these holes 1H12H and screwing the wood screws into a predetermined member, for example, as shown in FIG. In this case, hinge 1 is fixed to the door and hinge 2 is fixed to the mounting frame F.

According to the hinge device according to the present invention, while the lever 4 is fixed by the stopper 5, the pin 3 cannot rotate and the hinge 2 does not separate from the hinge 1. Therefore,
The pin 3 functions as a pin shaft when opening and closing the door. When it is desired to remove the door handle from the mounting frame F, the stopper 5 is displaced to free the movement of the lever 4, and the lever 4 is rotated. Then, depending on the position of the door, the notch direction H of the notch 3S of the pin 3 is aligned with the opening 2T of the engaging part 2F.
This means that the door handle can be easily removed from the mounting frame F.

When attaching the door handle to the mounting frame F, this is also done by swinging the lever 4 in the same manner.

Although the features of the hinge device of the present invention are as described above, the scope of the present invention is not limited by the contents of the above description and drawings, and may include various modifications without departing from the gist. 0 For example, in the case of the illustrated example, a lever and a stopper are attached, but the present invention is basically characterized in that a notch is provided in the pin, and the pin is not provided with a lever or a stopper. may be fixedly held on the convex engaging portion. In that case, when removing the hinge, all you have to do is rotate the hinge around the pin. Of course, the attachment of a lever and its stopper as shown in the illustrated example improves operability and provides a practical device, but even in that case, the shape of the stopper.

The structure is not limited to the illustrated example. For example, an unevenness is formed around the end of the engaging part 1 of the hinge 1, and a tilting type locking lever attached to the pin is engaged with the unevenness, so that it can be formed at an arbitrary angle. It can also be configured to fix the rotation of the bottle.

Also, the stopper can be attached to the same hinge as the lever. Furthermore, this hinge device is applicable not only to doors but also to various members.

〔Effect of the invention〕

Since the present invention is constructed and operates as described above, when the hinge device according to the present invention is used, it is possible to extremely easily engage and disengage a pair of swingably engaged members. For example, when applied as an engagement hinge device for an entrance/exit door of a house, the door can be attached and detached from the mounting frame relatively easily and in a short time.
