Description

[Detailed description of the invention] The present invention relates to a hinge applied to door attachment.

Generally, in order to open and close a thick door, it must be made into a hinged type.

Furthermore, in order to make it convenient to take things in and out, a hinge is required that allows the door to be opened to a large degree when taking things out.

To meet this requirement, it is sufficient to connect the mounting body fixed to the door mounting frame and the socket buried in the door using an appropriate link mechanism.From this point of view, even conventional hinges can be There are some that have reached this level.

However, if the hinge is mounted across the inner surface of the door mounting frame and the inner surface of the door, so-called a fleshy type, it is better that the link mechanism does not protrude into the storage space when the door is closed, and this is due to the appearance of the hinge. This is not just a matter of reducing the amount of storage space (in other words, it is necessary to prevent damage to the stored items due to the link mechanism that protrudes when the stored items are placed close to the inner surface of the door. In other words, it is necessary to use the storage space as effectively as possible. Technical considerations are currently required.

From this point of view, conventional examples satisfy the requirements of being a portable type and having a large door opening angle, but in most conventional examples, the link mechanism is thick (protruding) into the storage space. Therefore, technical issues still remain in this respect.

The present invention is the result of studies in view of the above-mentioned conventional circumstances.

We devised a special loss link, and with this cross link,
By appropriately connecting the hinge mounting body and the socket, the problem of the protrusion of the link mechanism is solved while satisfying the requirements of being a portable type door and having a large door opening degree.

The present invention will be explained in detail below based on the drawings showing specific examples of implementation.

In FIGS. 1 to 3 showing the first embodiment, a mounting body 2 fixed to a door mounting frame 1 and a cup-shaped socket 4 buried in a door 3 are connected by a cross link 5 as follows. Constructed by connecting.

That is, the cross link 5 is connected to the front end of the mounting body 2,
The main arm 5a is pivotally connected to the front end of the socket 4 by a shaft pin 6°7 at each end, and the sub arm 5b is pivotally connected to the front end of the socket 4 by a shaft pin 8, and the main arm 5a is formed into a substantially X-shape on the side. It is.

Here, the main arm 5a has a first bent part 5a' and a second bent part 5a'.
The side surface has an approximately 1-shaped bent portion 5a, and the first
When changing from the closed door position shown in the figure to the open door position shown in FIG. A cross link 5 is formed.

Further, the mounting body 2 has a lower front end formed with a cutout part 2a which slopes downward, conveniently for the sub-arm 5b to move in the front-rear direction to obtain the above-mentioned lifting amount l, and In the closed door state shown in the figure, the rear half of the sub arm 5b can be received.

Next, support arms 9 and 10 are pivotally attached to the front and rear ends of the sub arm 5b of the cross link 5, respectively, by shaft pins 11 and 12, and the other end of one of the support arms 9 is attached to the front end of the socket 4. , and the other end of the other support arm 10 is pivotally connected to the mounting body 2 by shaft pins 13 and 14, respectively, and the above-mentioned sub arm 5
b is configured to be slidable in the front and rear directions.

The mounting body 2 is mounted on a mounting plate 15 which is fixed to the door mounting frame 1 with screws (not shown) using a set screw 16 and an adjusting screw 17 so that the mounting position can be adjusted.

In the above configuration, the mounting body 2 is fixed to the door mounting frame 1, and the socket 4 and the door 3 are fixed, and the door 3 is mounted to the mounting frame 1 so as to be openable and closable.
In the closed door state shown in the figure, each rear half of the main arm 5a and sub arm 5b of the cross link 5 is supported within the cutout 2a at the lower front end of the mounting body 2, and the front half of the arms 5a, 5b are supported. Since the arms 9 are each received in the socket 4, the portion of the door mounting frame 1 that protrudes into the cabinet is only the mounting body 2, which is extremely small (in this state, the door cannot be completely closed). Become.

When the door is opened from the above-mentioned closed state as shown in FIGS. 2 and 3, the main arm 5a of the cross link 5 is rotated clockwise about the shaft pin 6, so that the main arm 5
The pivot point between a and the sub arm 5b, that is, the position of the shaft pin 8 moves forward.

Therefore, the cross link 5 is expanded and the sub arm 5b is
The lifting amount l is obtained by sliding forward from the position shown by the dotted line in the figure to the position shown by the solid line in the figure.

That is, this is because the sub arm 5b is movably connected to the mounting body 2 and the socket 4 by the support arm 9.degree. 10.

Therefore, the door opening operation is further performed at a position where the door 3 is advanced by the above-mentioned lifting amount l, and the door 3 is rotated to a position where the main arm 5a, the support arm 9, and the front end of the socket 4 come into contact with each other. It becomes an open door end.

Therefore, by obtaining the above-mentioned lifting amount l, it is possible to pivot a door with a correspondingly large thickness, and
According to the first embodiment described above, the opening/closing angle θ is 130° or more.
It is something that can be obtained.

Next, in FIGS. 4 and 5 showing the second embodiment,
The support arm 9 in the above-mentioned first embodiment is abolished, and the sub arm 5b of the cross link 5 is bent into a substantially horizontal L-shape, and its bent end sb' is connected to the socket 4 by a slide mechanism 18. The rest is the same as the first embodiment described above.

Further, in FIGS. 6 and 7 showing the third embodiment, the rear end 5b" of the sub arm 5b of the cross link 5, which is formed similarly to the first embodiment, and the mounting body 2, The components are connected by a slide mechanism 18, and the rest is the same as the first embodiment described above.

Further, in FIGS. 8 and 9 showing the fourth embodiment, the bent end 5b' of the sub arm 5b and the rear end 5 of the cross link 5, which is bent in the same manner as in the second embodiment, are shown.
b// is connected to the socket 4 and the mounting body 2 by a slide mechanism 18, and the rest is the same as the first embodiment described above.

The slide mechanism 18 includes a slide pin 18a protruding from the bent end 5b' and the rear end 5b'' of the sub arm 5b;
The mounting body 2 and a slide groove 18b formed in the socket 4 are slidably engaged with each other.

Therefore, in each of the second, third, and fourth embodiments, the sub arm 5b can obtain the extension amount l, so that the same opening/closing angle θ as in the first embodiment can be obtained. , which can achieve the same purpose and effect.

As explained above, according to the hinge of the present invention, the mounting body fixed to the door mounting frame and the socket buried in the door are flexibly and extensibly connected via the link mechanism, and these mounting bodies and the socket are connected to the door mounting frame. In the hinges attached to the inner surface of the mounting frame and the inner surface of the door, the cross link swings between the main arm, which has a first bent portion and a second bent portion and forms a side path, and the mounting body and the socket. The two arms are pivotally connected to each other at a portion where the first bending part of the main arm and the longitudinal middle part of the sub arm overlap, and one end of the main arm is connected to the mounting body. The other end of the main arm is pivotally connected to the upper front end of the socket, and the one end of the sub arm is attached to the mounting body via a swing support mechanism. The main arm is interconnected with the lower front end and the other end of the main arm is also interconnected with the inner front end of the socket via a swing support mechanism, and the cross link and swing support mechanism are in the closed state. It is characterized by a size that fits within the height of the inside of the socket and the mounting body, and the connection structure between the mounting body and the socket using a cross link and swing support mechanism makes it possible to open a large door in a portable type. Of course, you can get a degree,
When the door is closed, each member that makes up the cross-link and swing support mechanism fits inside the socket, below the height of the mounting body, so there is no problem of the link mechanism protruding excessively (therefore, the inner surface of the door Even if stored items are put in, the stored items will not be damaged by the link mechanism, and the storage space can be effectively utilized.
