Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field related to a double hinge, in which a door is pivotally attached to a side plate such as a cabinet or the like from a closed position inward and outward from a closed position.

[0002]

2. Description of the Related Art In recent years, barrier-free housing has been promoted in preparation for the coming of an aging society. For example, around the washroom, measures have been taken, such as eliminating the steps between the toilet and the bathroom, in order to secure the safety of the feet and facilitate the use of the wheelchair.

[0003] However, in a wash cabinet installed in a washroom, the storage space under the counter is generally covered with an open door, so that when the device is used in a wheelchair, the door becomes an obstacle and the wash cabinet is installed in the wash cabinet. Difficult to meet. Note that there is a similar problem in a kitchen cabinet.

[0004] If the door of the wash cabinet or kitchen cabinet is opened inward, use in a wheelchair becomes easy. However, if the door is simply opened inward, it becomes difficult to store equipment and the like in the storage space, and when the wheelchair is not used, there is a problem that the storage space cannot be utilized. Therefore, in order to accommodate both a user who uses a wheelchair and a user who does not use a wheelchair, doors of a wash cabinet, a kitchen cabinet, and the like need to be pivotally attached to the inside and outside so as to be able to open in both directions.

[0005] As a metal fitting for pivotally connecting a door so that it can be opened as described above, for example, a double hinge as disclosed in Japanese Patent No. 2859858 is known. The double hinge has a biaxial structure in which a pair of blade plates are pivotally connected via a connecting plate so as to be foldable in a Z-shape. A pair of catch mechanisms are provided between the pair of blade plates and the connecting plate so that they can be held in a Z-shaped state.

[0006]

When a door of a cabinet or the like is pivotally connected to the inside and outside from a closed position orthogonal to the side plate by using the double hinge, one of the blade plates is connected to the inner surface of the door. , The other wing plate must be fixed to the edge of the side plate. Similarly, if one blade is fixed to the inner surface of the side plate, the other blade must be fixed to the opening of the door. However, since the opening of the side plate or the door is generally narrow and the screw is hard to work, it is difficult to firmly pivot the door to the side plate in the double hinge.

[0007] The present invention has been made in view of such problems, and the door can be firmly pivoted to the side plate.
An object of the present invention is to provide a double hinge capable of securely holding a door in a closed position orthogonal to a side plate and capable of pivotally opening the door from the closed position inward and outward.

[0008]

In order to solve the above-mentioned problems, a double hinge according to the present invention employs the following means. That is, the feature of the double hinge according to claim 1 is that, when one of the side plates or the door is a first plate member and the other is a second plate member, a fixing piece and a first piece that can be fixed to the inner surface of the first plate member. A wing member having a substantially L-shape having an abutment piece that can be joined to the opening of the plate member and having an outwardly open hinge protruding from the abutment piece; and a flange portion that can be fixed to the inner surface of the second plate member. And a cup portion that can be embedded in the inner surface of the second plate member with one end facing the opening of the second plate member, one end of the cup portion being opened, and an inwardly-opening hinge portion being opened to the other end of the cup portion. Is provided, and one end is pivotally attached to the outwardly opening hinge of the wing member via an outwardly opening pivot, and the other end is pivotally attached to the inwardly opening hinge of the cup member via the inwardly opening pivot. A link member, the link member being a wing member in the closed position of the door. The contact piece and the bottom of the cup portion of the cup member are in contact with each other, and the other end is configured to protrude beyond the fixing piece of the wing member. When the door is engaged at the closed position and the door is opened outward with the pivot open as a fulcrum, an outward-opening catch mechanism capable of releasing the engaged state is provided. In the meantime,

Is fixed, the first plate member and the second plate member are firmly pivotally connected. In this pivoted state, when the first plate member is a side plate and the second plate member is a door, when the door is closed at a position where the door is orthogonal to the side plate, the outward-opening catch mechanism moves outwardly on the wing member side. Since the opening hinge portion and the link member are engaged, and the inward opening catch mechanism engages the inward opening hinge portion on the cup member side with the link member, the closed state of the door is maintained. Then, when the door is pushed inward from the closed position of the door, the link member comes into contact with the contact piece of the wing member, and the inward rotation of the door about the pivot opening pivot is regulated. The pivot point moves to the inward pivot. At this time, since the inward-opening catch mechanism releases the engagement state between the inward-opening hinge portion and the link member, the door rotates inward about the inward-opening pivot. Further, when the door is pulled outward from the closed position of the door, the bottom surface of the cup portion of the cup member comes into contact with the link member, and the pivoting of the door around the inwardly opened pivot is restricted, so that the rotation of the door is prevented. The fulcrum moves to the outward pivot. At this time, since the outward-opening catch mechanism releases the engagement state between the outward-opening hinge portion and the link member, the door pivots outward about the outward-opening pivot. The same applies to the case where the first plate member is a door and the second plate member is a side plate.

Therefore, according to the double hinge of the first aspect, the door can be firmly pivotally attached to the side plate, the door can be securely held at the closed position orthogonal to the side plate, and the door can be moved from the closed position to the inside and from the closed position. It can be pivotally attached to the outside so that it can be opened.

In the double hinge according to the second aspect,
A fixing piece of the wing member is fixed to an outer surface of the first plate member,
Since the flange portion of the cup member is fixed to the inner surface of the second plate member, the first plate member and the second plate member are firmly pivotally connected. In this pivoted state, when the first plate member is a side plate and the second plate member is a door, when the door is closed at a position where the door is perpendicular to the side plate, the outwardly opening catch mechanism is located outside the cup member. Since the opening hinge portion and the link member are engaged, and the inward opening catch mechanism engages the inward opening hinge portion on the wing member side and the link member, the closed state of the door is maintained. Then, when the door is pushed inward from the closed position of the door, the bottom of the cup portion of the cup member abuts on the link member, and the rotation of the door around the pivot opening is restricted, so that the door is closed. The pivot point moves to the inward pivot. At this time, since the inward-opening catch mechanism releases the engagement state between the inward-opening hinge portion and the link member, the door rotates inward about the inward-opening pivot. Further, when the door is pulled outward from the closed position of the door, the link member abuts against the contact piece of the wing member, and the outward rotation of the door about the inwardly opened pivot is regulated. The fulcrum moves to the outward pivot. At this time, since the outward-opening catch mechanism releases the engagement state between the outward-opening hinge portion and the link member, the door pivots outward about the outward-opening pivot. The same applies to the case where the first plate member is a door and the second plate member is a side plate.

Therefore, according to the double hinge according to the second aspect, the door can be firmly pivotally attached to the side plate, the door can be securely held at the closed position orthogonal to the side plate, and the door can be moved inward and outward from the closed position. It can be pivotally attached to the outside so that it can be opened.

In the double hinge according to the third aspect,
When the first plate member is used as a side plate and the second plate member is used as a door and the two are pivotally connected, at the closed position of the door, the link member, the outward-opening catch mechanism and the inward-opening catch mechanism are accommodated in the cup portion of the cup member. And placed within the thickness of the door.
Similarly, when the first plate member is a door and the second plate member is a side plate, the link member, the outward-opening catch mechanism, and the inward-opening catch mechanism are arranged within the thickness of the side plate. Therefore,
According to the double hinge of the third aspect, the gap between the inner surface of the door and the opening of the side plate or the gap between the inner surface of the side plate and the opening of the door can be minimized.

According to the double hinge according to the fourth aspect, at least four of the outer cam and the outer slider constituting the outer catch mechanism and the inner cam and the inner slider constituting the inner catch mechanism are provided. The durability of the outward-opening catch mechanism and the inward-opening catch mechanism can be improved only by making the material of the component a material having high wear resistance.

According to the double hinge of the fifth aspect, the opening adjusting screw is screwed into the opening adjusting screw hole provided in the link member, and the amount of the screw is adjusted, whereby the cup of the wing member is adjusted. By adjusting the angle with respect to the member, and subsequently correcting the angle of the door with respect to the side plate, it is possible to easily solve the problem of the door being shaken.
