Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge applied to the installation of a door.

Generally, in order to open and close a thick door, the hinge must be of a corbelled type.Furthermore, in order to make it convenient to take things in and out, a hinge that can be set to a large degree to open the door is required. .

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 do not meet the specified technical level. It can be seen that some have reached this level.

However, in the case of a so-called internal type hinge, in which the hinge is mounted across the inner surface of the door mounting frame and the inner surface of the door, 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 external appearance of the hinge. This is not just a low-level problem, but 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. Technical consideration is currently required.

From this point of view, the conventional example satisfies the requirements such as being a portable type and having a wide door opening, but most conventional examples have a structure in which the link mechanism protrudes greatly into the storage space. Technical issues still remain in this respect.

The present invention was developed in view of the above-mentioned conventional circumstances.
We devised a special cross link and added this to
By combining with a type link and appropriately connecting the hinge mounting body and socket using the link mechanism, it satisfies the requirements of being a portable type and having a large door opening, while also solving the problem of the link mechanism protruding. This is what I did.

First, in FIGS. 1 and 2 showing the first embodiment, the hinge A includes a mounting body 2 fixed to the door mounting frame 1, and a cup-shaped socket 4 embedded and fixed to the door 3. They are connected by a link mechanism 6.

Further, the mounting body 2 is provided with a cutout portion 5 that is sloped downward and cut out at the lower side of the front end, and the link mechanism 6
The mounting plate 7 is conveniently provided to accept the door mounting frame 1 and is fastened to the door mounting frame 1 with screws.
The mounting position can be adjusted and fixed using a set screw and an adjustment screw (not shown).

On the other hand, the cup-shaped socket 4 is fitted and fixed in a mounting recess 8 formed inside the door 3.

Thus, the link mechanism 6 connecting the mounting body 2 and the socket 4 consists of a front cross link 6' and a rear X-shaped link 6'', and the cross link 6' has a first bent portion 9a and a second bent portion. The main arm 9 has a substantially square-shaped side surface and has a sub-arm 10 that swings between the socket 4 and the mounting body 2.
are pivotally connected to each other by a shaft pin 11 at a portion where the longitudinal intermediate portion of the sub-arm 10 and the first bent portion 9a of the main arm 9 overlap, and at least one pair of cross-links 6' are interposed behind the cross-link 6'. The X-shaped link 6'' has a long arm 12 and a short arm 13 that cross each other at the center and are pivotally connected by a shaft pin 14, and the front ends of the long arm 12 and short arm 13 are connected to the main arm 9 and the sub arm. Axle pin 1 at the rear end of 10
5 and 16, respectively, and the main arm 9
The front end of the short arm 13 is pivotally connected to the inner front end of the socket, and the rear end of the short arm 13 is connected to the mounting body 2.
are mutually pivotally connected to the upper front end of.

According to the first embodiment, support arms 1 are provided at the front end of the sub arm 10 and the rear end of the long arm 12, respectively.
9 and 20 are pivotally connected by shaft pins 21 and 22, and the other ends of these support arms 19 and 20 are pivotally connected to the front part of the socket 4 and slightly rearward from the front end of the mounting body 2 by shaft pins 23 and 24, respectively. The hinge A is constructed as follows.

Here, support arms 19 and 20 connecting the sub arm 10 and the long arm 12 to the socket 4 and the mounting body 2 are shown.
is provided to support both the arms 10, 12 in a predetermined direction in the front-rear direction and to enable them to swing by a desired stroke. The connection is not limited to the above-mentioned support arms 19 and 20, but can also be made by a swinging support mechanism consisting of a slide mechanism or a combination of a support arm and a slide mechanism, as will be made clear in each embodiment described later. The link mechanism 6 can operate in the same manner as described above.

In the above configuration, the hinge A of the present invention
Since the door 3 is attached to the door mounting frame 1 as described above, when the door is closed, the link mechanism 6 is reduced in volume as shown in FIG. is received in the socket 4 and the rear part is received in the cutout 5 of the mounting body 2, respectively, and the rear part is received in the cutout 5 of the mounting body 2.
It only slightly protrudes into the cabinet.

When the door is opened from the closed door position, the socket 4, that is, the door 3, is opened by the main arm 9 and the support arm 1.
As a result, the main arm 9 and the support arm 19 rotate clockwise around the shaft pins 15, 21 as fulcrums. The positions of both move forward, the link mechanism 6 expands as shown in FIG. 2, and the sub arm 10 and the long arm 12 slide forward to obtain a lifting amount l.

In other words, since the sub arm 10 and the long arm 12 are movably (rotatably) connected to the socket 4 and the mounting body 2 through the support arms 19 and 20, they can slide forward as the link mechanism 6 is expanded. .

In addition, the link mechanism 6 has a larger overall expansion and contraction amount than a single X-type link, so the above-mentioned lifting amount l can be made considerably large, so that a sufficient l can be obtained. After that, socket 4 is
The front edge rotates until the main arm 9 and support arm 19 come into contact with each other, resulting in an open door end.
The opening/closing angle Θ of the door 3 can be set to 150° or more in the illustrated example.

In addition, since the lifting amount l can be increased as described above, it is possible to maintain a large distance between the front end of the door mounting frame 1 and the door 3, making it possible to install a door with a large plate thickness. It will become.

Next, the second embodiment of the present invention is shown in FIG.
The link mechanism 6 is connected to a cross link 6' and two sets of X
The main arm 9 and the sub arm 10 and the long arm 12 and the short arm 13 are cross-pivoted to each other by a shaft pin 25 at the center. The front and rear ends of 26 and short arm 27 are connected to shaft pins 15, 16, 2, respectively.
8 and 29, and the other parts are constructed in the same manner as in the first embodiment.

According to the second embodiment, the amount of expansion and contraction of the link mechanism 6 can be made larger than that of the first embodiment.
Furthermore, the lifting amount l can be set to a large value, and the opening/closing angle Θ can be further increased.

Further, in FIGS. 4 and 5 showing the third embodiment, the link mechanism 6 is formed in the same manner as in the first embodiment, and the long arm 12 and the mounting body 2 are connected to the slide mechanism. 30, and the other parts are formed in the same manner as in the first embodiment described above.

Here, the slide mechanism 30 is formed by slidably engaging a slide pin 30a protruding from the long arm 12 and a slide groove 30b recessed in the mounting body 2.

Furthermore, the sixth example shows the fourth example and the fifth example.
7, the sub-arm 10 is bent into a substantially L-shaped side surface, and its bent end 10a is directly connected to the socket 4 by a slide mechanism 30, so that the sub-arm 10 in both the first and third embodiments is In the fourth embodiment, the support arm 19 is eliminated, and the long arm 12 and the mounting body 2 are pivotally connected by a support arm 20 in the same manner as in both the first and second embodiments. In this case, they are connected by a slide mechanism 30 as in the third embodiment.

Here, the slide mechanism 30 is formed of a slide pin 30a and a slide groove 30b, as in the case of the third embodiment, and the slide pin 30a is protruded from the bent end 10a of the sub arm 10, and the socket 4 has a slide groove 30b recessed therein and is engaged therewith so as to be relatively slidable.

According to the third, fourth, and fifth embodiments, the socket 4, the mounting body 2, the sub arm 10, and the long arm 12 are combined with the support arms 19, 20 and the slide mechanism 30, or the slide mechanism 30 Since they are connected to each other by a single arm, the sub arm 1 is
0. The long arm 12 can be slid,
Therefore, since the above-mentioned protrusion amount l can be obtained, a wide opening/closing angle Θ can be obtained.

As explained above, according to the hinge according to the present invention, the mounting body 2 fixed to the door mounting frame 1 and the socket 4 buried in the door 3 are connected via the link mechanism 6 in a flexible and extensible manner. In the hinge A in which the mounting body 2 and the socket 4 are respectively attached to the inner surface of the door mounting frame 1 and the inner surface of the door 3, the link mechanism 6 consists of a front cross link 6' and a rear X-shaped link 6'', The cross link 6' includes a main arm 9 having a first bending part 9a and a second bending part 9b and having a substantially square shape on the side, and a sub-arm 10 that swings between the socket 4 and the mounting body 2. The arms 9 and 10 are pivotally connected to each other at a portion where the longitudinal intermediate portion of the sub arm 10 and the first bent portion 9a of the main arm 9 overlap, and at least One pair of interposed X-shaped links 6'' is formed by pivoting a long arm 12 and a short arm 13 such that they cross each other at the center, and the front ends of the long arm 12 and short arm 13 are connected to the main arm 9 and the short arm 13, respectively. Secondary arm 10
The front end of the main arm 9 is pivotally connected to the inner front end of the socket 4, and the rear end of the short arm 13 is pivotally connected to the upper front end of the mounting body 2. The front end of the sub arm 10 is connected to the inner front end of the socket 4 via a swing support mechanism, and the rear end of the long arm 12 is also connected to the front end of the mounting body 2 via a swing support mechanism. Since the cross link 6', the X-shaped link 6'', and the swinging support mechanism are characterized by being interconnected with the lower part, the lifting amount l can be set to be quite large due to the large amount of expansion and contraction. This makes it possible to install doors with considerably thick plates, as well as to reduce the opening/closing angle θ of the door 3.
For example, the cross link 6', Since each member constituting the mechanism is housed in an extremely small size, the problem of protrusion that occurs when the link mechanism protrudes excessively is eliminated, and therefore, even if the stored items are placed close to the inner surface of the door 3, the stored items will not be The storage space can be effectively utilized without being damaged by the link mechanism.
