By fixing to the left and right built-in links with a rotatable pin or the like, the operation of the left and right links is limited by the hinge movable side a, and the following movement is performed. The left link e opens and closes integrally with the hinge movable side a, and the right link f does not move when opened. The right link f opens and closes integrally with the hinge movable side a, and the left link e does not move when opened. [Selection] Figure 4

Description

Detailed description of the invention

Industrial application fields

  The present invention relates to a hinge or hinge opening / closing mechanism.

Conventionally, there are few mechanisms for opening and closing both sides of the door, and the existing technology required a shaft-shaped hinge that can rotate on both sides and some mechanism for preventing the door from falling off.
For this reason, it is necessary to manually release only the direction in which the mechanism for preventing the dropout is to be opened, which is troublesome. In addition, in the both-side open structure of the refrigerator which is now common, it is not necessary to manually unlock the refrigerator, but opening both sides also has the risk of the door body falling off, limiting it. It requires a complicated mechanism.
Also, in the above structure, when the door changes from the closed state to the open state, the door is fixed only on one side, and the one side is not a complete holding structure, so the door itself slightly shifts downward due to its own weight. It has become.
In addition, the double-sided opening method proposed in Japanese Patent Application Nos. 4-64280 and 2008-7631 is the same as the present invention in that it is a link type. However, in the present invention, the hinge itself incorporating the mechanism can be shown. It is a big difference.
In particular, in the structure of Japanese Patent Application No. 4-64280, the hinge for holding the housing and the door is almost the same as the length of the door. When the door is raised, the door falls downward due to its own weight. There is also a problem that it is substantially difficult to open and close.
The hinge internal mechanism in the present invention solves all of these problems.

Problems that the device tries to solve

In the first place, when hinges are attached to both sides to open and close both sides of the door, neither of the doors can be opened or closed. The conventional refrigerator technology that solves this problem is excellent, but at the same time, various mechanisms have to be added to solve the above problems. However, it is expensive and there is a risk that the mechanism will not fit in a small size and the door will fall in a huge size.
The present invention solves both of them, and realizes both sides opening with a very simple structure, and can be manufactured at low cost regardless of the size of the product.
In particular, in the present invention, the structure of the hinge itself incorporating these mechanisms is defined, and this makes it possible to provide a double hinge that can be easily attached to any object at low cost.

Means for solving the problem

In order to achieve the above object, the invention of claim 1 of the present application fixes the left link to the left side of the hinge fixing side with a rotatable pin or the like, and at the same time uses the pin or the like to rotate the right side link on the right side of the hinge fixing side. Start with fixing.
In this state, both the left and right links can operate without any restrictions.
Next, fix the left link to the right side of the hinge movable side with a pin that can rotate the hinge movable side, and the right link to the left side of the hinge movable side. So that the operation is limited.
When the right side of the hinge movable side is in the open state, the left link is also in the open state, and the right link needs to have the same center of rotation as the hinge movable side, so it is limited to the closed state.
When the left side of the hinge movable side is in the open state, the right link is also in the open state, and the left link is limited to the closed state because the center of rotation needs to be the same as that of the hinge movable side.
The invention of claim 2 of the present application shows a structure in which the link mechanism of claim 1 of the present application is housed inside the hinge.
In the invention of claim 3 of the present application, the hinge fixing side and the hinge movable side are stored in a state where the link is sandwiched between the hinge fixed side and the hinge fixed side when the hinge movable side is opened. ing.
Therefore, the dead weight of the door is applied to the hinge movable side as a moment, which hinders the closing operation.
However, in the present invention, when the hinge moves from the open state to the closed state, the link itself that exists between the hinge fixed side and the hinge movable side serves as a guide plate, and gradually moves from the pin base to the hinge movable side. Since it enters the inside of the hinge fixing side naturally, it is possible to shift to the retracted state without being affected by the weight of the door itself.
The invention of claim 4 of the present application is to provide a door that can be double-opened by attaching the hinge of claim 1 to the top and bottom or the left and right inside of the door.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a cross link type left and right hinge structure according to the present invention will be described below with reference to the drawings.

  In FIG. 1, this state is a state in which the hinge is opened from the right side of the hinge movable side “a” and rotated about 180 degrees to the left about the left link rotation axis “c” of the hinge fixing side “b”.

  In FIG. 2, this state is a state where the hinge is opened from the left side of the hinge movable side “a” and rotated about 180 degrees in the right direction around the rotation axis “d” of the right side of the hinge fixing side “b”.

  In FIG. 3, the locus | trajectory when the hinge movable side a moves to the left direction and the right direction is shown.

In FIG. 4, this mechanism mainly comprises a hinge movable side a, a hinge fixing side b, a left link e, and a right link f.
Because of this extremely simple structure, it can be applied to hinges of any shape, regardless of the hinge as shown in this figure.

In FIG. 5, this mechanism is simply shown. First, the h side of the link k is fixed to the housing n with a pin that can be rotated, and the i side of the link m is further rotated to the housing n with a pin that can be rotated. Hold in a fixed state. At the same time, link k and link l are connected by a rotatable pin or the like, and link m and link l are connected by a rotatable pin or the like.
When the link k is rotated in the direction B in this state, the link l is rotated and the link m does not rotate.
When the link m is rotated in the direction B, the link l is rotated and the link k does not rotate.
In other words, the explanation will be easy if the housing n is on the hinge fixed side and the link I is replaced with the hinge movable side.
Although this is not the same as the embodiment, it is an important element in considering the basic operation of the present invention, so it was added for explanation.

  In FIG. 6, the external appearance three-view figure as an Example of this invention form is shown.

FIG. 7 shows a state in which a hinge o is attached to a storage space provided in a step shape with respect to the housing p, and a door q is attached to the hinge o.
At this time, the hinge o is hidden by the door q and the appearance is improved.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and it will be apparent to those skilled in the art that various modifications and changes can be made within the scope of the claims.
