Abstract

[Problem] To provide a structure in which a cross-link type left-right opening hinge can be installed on the outside of the door in a single double door using a cross-link type left-right opening hinge. [Solution] In the door (e) using a cross-link type left-right opening hinge, a bent sheet metal material on the outside side (b) of the hinge is bent to create a structure that can be attached to the outside of the gate and the outside of the door, which are set flush.

Description

The present invention relates to a cross-linked left-right hinge for a double-door single door.

Doors have been used for various things such as furniture, control panels, refrigerators, automobiles, and buildings since ancient times. It is a structure that only opens and closes.
Japanese Patent Application Laid-Open No. 9-303942 proposes a double door structure for a refrigerator.
However, the structure is complicated, and it is difficult to support custom-made products of various dimensions other than refrigerators and small-lot production at low cost.
Moreover, this has the structure which installs a mechanism in a door inner side.
A cross-linked double door mechanism is also proposed in Japanese Utility Model Registration No. 3242008. This has a structure in which hinges are installed on the inside of the door.

General hinges are installed on the outside of the door, on the inside of the door, and on the side of the door. Hinges have a long history, and there is no need to discuss the technical content of each, but for the sake of explanation, I will briefly describe the advantages and disadvantages.
The most commonly used is the hinge installed on the outside of the door. The advantage of this is that there is a high degree of dimensional freedom with the door opening, and it is easy to install because there is little interference with the side surface when the door is opened. It is therefore widely used. On the other hand, the disadvantage is that the hinges are visible, so the appearance is inferior.
On the other hand, the advantage of the structure in which the hinge is installed inside the door is the beauty of its appearance.
However, there are restrictions due to the rotation center, and there are many restrictions on the dimensions with the doorway, making the installation work a little difficult.
For the above reason, the structure that is actually used overwhelmingly is to install hinges on the outside of the door.
Unfortunately, until now, all single-piece doors that open to the left and right using cross-link double-opening hinges have had a structure in which the hinges are installed inside the door, and there have been major restrictions on their use.

In a door using a cross-link type left-right opening hinge, by bending a sheet metal bending material on the outside of the hinge, the structure is made so that it can be attached to the outside of the gate and the outside of the door which are set flush.

The following effects can be obtained by installing the cross-link type left-right opening hinge on the outside of the door.
Even if the gap between the side of the gate and the door is set to 1 mm or less, there is no interference with the door when opening and closing.
Since it does not protrude from the side of the gate when opening and closing, there is no interference with the side.
Even if the center of rotation of the hinge is roughly set, the door can be opened and closed.
Good workability because hinges can be retrofitted.
Due to the above advantages, it can be used as a modification to an existing door.
In other words, it is expected that the range of application will be greatly expanded compared to the conventional method of attaching hinges to the inner side of the door.

Fig. 3 shows a horizontal cross-sectional view of the structure for mounting the cross-link type left-right hinge on the outside according to the present invention; Fig. 2 shows a vertical cross-sectional view of an external mounting structure for a cross-link type left-right hinge according to the present invention; FIG. 10 is a cross-sectional view of a hinge body having a structure in which a cross-link type left-right opening hinge according to the present invention is attached to the outside; An example of the external view of the hinge of the structure which attaches the cross link type left-right opening hinge concerning this invention outside is shown.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a single double-opening door related to the present invention will be described below with reference to the drawings.
In FIG. 1, the cross-link type left-right opening hinge d is installed on the outside of the door with respect to the gate f and the door e.
In FIG. 2, the inner side a of the cross-link type left-right opening hinge is installed on the outer side of the gate top g.
The hinge outer side b is installed on the outer side of the door e.
Further, the hinge inner side a and the hinge outer side b are connected by a link c.
In FIG. 3, the cross-link type left-right opening hinge has a hinge inner side a and a hinge outer side b connected by a link c.
Further, the hinge outer side b is set flush with the hinge inner side a by folding back. As a result, it has a structure that can be attached to the outside of the door.
In FIG. 4, the hinge inner side a and the hinge outer side b are connected by a link c.

As shown in [Fig. 2], a cross-link type left-right opening hinge is installed on the outside of the door.

By adopting a cross-link type left-right opening hinge that can be installed with an overwhelming degree of freedom, it can be used as a door in almost all industrial fields, from a palm-sized door to an ultra-heavy door.
At the same time, it is easy in terms of design, and if a cross link type left and right opening hinge is obtained as a part, it is possible to easily manufacture a single double door.
Also, it becomes possible to modify an existing door.
