Abstract

[Problem] To solve the phenomenon that both sides of a double-opening one-piece door using cross-link type left-right opening hinges tend to open due to play generated at the beginning of the opening of the door. It also provides a structure that realizes safe and smooth operation. A door using a cross-link type left-right opening hinge has a structure in which a spring plunger d is installed at the rotation center of both sides of the hinge. [Selection drawing] Fig. 1

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.
A cross-link type left-right opening hinge is proposed in Japanese Utility Model Registration No. 3149050. As a result, a structure is proposed in which both the left and right sides of a single door can be opened and closed. However, if you try to apply this to a general door that stands vertically on the ground, the upper part of the door will fall down first due to the play of the hinge at the beginning of opening, and it cannot be used in reality.
A cross-linked double door mechanism is also proposed in Japanese Utility Model Registration No. 3145918. This is low cost and can be customized, but is only suitable for opening and closing when placed horizontally on the ground as shown in the proposed drawing.

Japanese Patent Application Laid-Open No. 9-303942 Utility Model Registration No. 3149050 Utility Model Registration No. 3145918

When opening and closing a door set in a direction perpendicular to the ground with a cross-link type left-right opening hinge of Utility Model Registration No. 3149050, the upper part of the door falls down first due to the weight of the door at the beginning of opening.
Unlike normal hinges, the cross-link type left-right opening hinge inevitably has a large amount of play at the start of operation because both the left and right sides are opened and closed.
Due to this play, when the door starts to open, the upper part of the door inevitably falls down first, which is dangerous and practically unusable.
For this reason, it has only been used for doors that are set horizontally with respect to the ground, as in Utility Model Registration No. 3145918.
The present invention intends to eliminate the trouble caused by the play at the beginning of opening the door, and to provide comfortable and safe operation even for the door set perpendicular to the ground.
Also, unlike Japanese Patent Application Laid-Open No. 9-303942, by using the cross-link type left-right opening hinge of utility model registration No. 3149050, it is intended to cope with various custom-made products and small-lot production at low cost.
At the same time, it becomes possible to supply not only door assemblies but also individual parts.
As a practical matter, I would like to add that the majority of demand for doors is for doors that are set perpendicular to the ground.

In a door using a cross-link type left-right opening hinge, a structure is adopted in which a spring plunger is installed at the center of rotation on both sides of the hinge.

Due to the effect of the spring plunger installed at the center of rotation on both sides of the cross-link type left-right opening hinge, the play of the cross-link type left-right opening hinge that occurs when the door starts to open is eliminated, eliminating problems such as the door falling over.
At the same time, the effect of the spring plunger also has the effect of maintaining the closed state of the door.
Since this one-piece door is always connected to the frame, there is no danger of falling off. On top of that, safe and comfortable opening and closing operations are now possible.
This cross-link type left-right opening hinge is not limited to door assemblies, and it is now possible to supply individual parts.
With this idea, it became possible to manufacture a wide range of doors from small to large at a relatively low cost without restrictions.

Fig. 2 shows a top view of the structure in which the spring plunger is installed in the cross link type left and right hinge according to the present invention; Fig. 2 shows a front view of a structure in which a spring plunger is installed in a cross link type left and right opening hinge according to the present invention; FIG. 10 is a right side view of the cross-link type left-right opening hinge with a spring plunger installed according to the present invention; 1 shows an example of an embodiment of a cross link type left and right opening door according to the present invention.

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 has a hinge upper side a and a hinge lower side b connected by a link c.
Also, the spring plunger d is installed at both rotation centers on the lower side b of the hinge.
In FIG. 2, the cross-link type left-right hinge is shown with an upper hinge side a and a lower hinge side b.
Also, the spring plunger d is installed at both rotation centers on the lower side b of the hinge.
In FIG. 3, the cross link type left-right opening hinge has a hinge upper side a and a hinge lower side b connected by a link c.
In addition, the spring plunger d is installed at both rotation centers of the upper side a of the hinge.
[Fig. 4] shows a top view of a double-opening single-leaf door using a cross-link type left-right hinge and the opening and closing trajectory of the door.

In a double-opening single-piece door, by using a cross link type left-right opening hinge with a spring plunger installed at the center of rotation on both sides, a safe and smooth operation of a double-opening single door as shown in [Fig. 4] is realized.

Due to its simple structure, it can be used in a wide range of applications such as furniture, home appliances, buildings, automobiles, trucks, control panels, switchboards, and machine tools.
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.
Moreover, since the frame and the door are always connected, the risk of the door falling off is reduced.
