Description

Detailed description of the device

Industrial application fields

  The present invention relates to a mobile phone, a stationery, a toy, an electronic device, a machine tool, a factory facility, furniture, a home appliance, a tool box, a private car, a freight car, a building, and an opening / closing mechanism of a building.

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 side in which the drop prevention mechanism is to be opened, which is troublesome. In addition, in the both-side open structure of the refrigerator that 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, preventing and 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. It has become.

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.
Moreover, since the material is a very simple structure, any material such as metal, wood and plastic can be manufactured.

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 door or the like to the casing with a rotatable hinge, etc., and simultaneously fixes the right link door or the like to the casing with a rotatable hinge or the like. It starts with that.
In this state, both the right and left link doors can be opened and closed without any restriction.
Next, by fixing the central link type door etc. to the left and right link type doors etc. with a rotatable hinge etc., the operation of the left and right link type doors etc. is restricted as follows by the central link type door etc. .
When the left link type door or the like and the central link type door are in the open state, the right link type door or the like needs to have the same rotation center, and therefore the right link type door or the like is limited to the closed state.
When the right link type door or the like and the central link type door or the like are in the open state, the left link type door or the like needs to have the same rotation center, so the right link type door or the like is limited to the closed state.

The invention of claim 2 of the present application is that the hinges connecting a total of three doors, such as the left and right link doors and the central link door, do not interfere with the door itself unless the center of rotation is placed on the opening and closing direction side of each door. Therefore, it is impossible to rotate 180 degrees, so that a hinge is usually externally attached and the appearance shape is deteriorated.
In order to solve this problem, the link doors on the left and right sides are attached slightly retracted from the link doors in the center, and each is fixed with a hinge that can be connected in that state. At the same time, if it is covered with a terminal such as a central link door, it will be invisible.

  The invention of claim 3 of the present application is to improve the appearance by covering the link itself such as the left and right link type doors with the main body such as the central link type door.

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

  In FIG. 1, this state is opened from the right side of the door, etc., and the right link door a, etc. and the central link door, etc. b are integrated about 180 to the left with the holding part d of the housing f as the center of rotation. It shows the state rotated by a degree.

  In FIG. 2, this state is opened from the left side of the door, etc., and the left link door c, etc. and the central link door b, etc. are integrated with the holding part e of the housing f as the center of rotation about 180 in the right direction. It shows the state rotated by a degree.

In FIG. 3, the right link type door etc. a and the central link type door etc. b move together, and the left link type door etc. c move together with the central link type door etc. b.
As described above, since the operation of the left and right link doors a and c is restricted by the central link door b or the like, they are not simultaneously opened even if they are not fixed by a lock or the like.
Further, since the left and right link type doors are fixed in advance to the rotation center portions d and e of the housing f with hinges or the like, no drop-off accident occurs.
At the same time, when the transition from the open state to the closed state occurs, the link itself serves as a guide, so that the transition is made to the fully closed state without any steps.

In FIG. 4, this mechanism is mainly composed of a right link type door etc. a, a central link type door etc. b, a left link type door etc. c, a housing etc. f.
Because of this extremely simple structure, it is not limited to the box shape as shown in this figure, but it can be applied to any shape of housing, the direction of usage, the shape of the left and right link doors, and the center of rotation. Various applications, such as movement to both outsides, can be made.

  In FIG. 5, the mechanism is such that the left link type door c and the central link type door b are not leveled and are kept in a stepped state and are connected by a hinge or the like so that the hinge itself is connected to the central link. It can be covered with a type door or the like and can be opened and closed 180 degrees.

  In FIG. 6, this mechanism can cover the housing side guide j of the f portion of the housing etc. with the central link door b. At the same time, the link itself such as the right and left side link type doors can be covered and the aesthetic appearance can be 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.

Effect of device

  As described above, according to the opening / closing mechanism of the present invention, the left link door, etc. and the right link door, etc. are fixed to the left and right sides of the housing with a rotatable hinge, etc. If the door is fixed with a hinge that can be rotated, it will be possible even if the door that can be opened or closed on both sides does not have a locking mechanism. If the left and right link doors are shifted from the central link door, the hinges etc. are covered with the central link door, etc., and if the left and right links themselves are covered with the central door, the appearance can be improved. It becomes possible.
