Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge which is preferably used for connecting a hanging door and an opening door of a folding door. More specifically, it prevents knocking of the door and smooth opening and closing of the door. A hinge that realizes damage prevention.

[0002]

2. Description of the Related Art A folding door used for closing an opening of a closet is formed by connecting a hanging door 60 and an opening door 62 by a hinge 64 so as to be foldable, as shown in FIG. There is. The hanging door 60 has an upper rail 6 so that the hanging door 60 can rotate around one end side in the width direction (left side in the drawing).
6 is mounted between the lower rail 68 and the lower rail 68, and the opening door 62 is slidable along the upper rail 66 and the lower rail 68 so that one end side in the width direction (right side in the drawing) slides along the upper rail 66 and the lower rail 68. It is installed between. In the figure, 70 is an upper frame to which the upper rail 66 is fixed, and 72
Is a lower frame to which the lower rail 68 is fixed, 74 and 74 are vertical frames, and 76 is a handle.

In the folding door 78 shown in FIG. 7, when the handle 76 is pulled toward you, the hanging door 60 rotates around one end in the width direction and one end in the width direction of the opening door 62 runs along the rails 66 and 68. By sliding the door
0 and the opening door 62 are folded to open the folding door 78.

[0004]

[Problems to be Solved by the Invention] The folding door 7 shown in FIG.
Pulling the handle 76 from the state where 8 is closed, the folding door 78
When the door is opened, as shown in FIG. 9, the hanging door 60 and the opening door 6
2 becomes almost parallel. In this state, when pushing the handle 76 to close the folding door 78, or when a horizontal or diagonal force is applied to the doors 60 and 62 when a person hits the hanging door 60 (see the arrow in the figure), Knocking may occur.

Knocking of the door means that, as shown in FIG. 10, when a lateral or diagonal force is applied to the doors 60 and 62, one end side of the opening door 62 in the width direction is displaced to the direction of the hanging door 60. This is a phenomenon in which the opening door 62 does not move between the rails 66 and 68 even if the opening door 62 does not move due to the collision with the door 60 and a lateral or diagonal force is applied to the hanging door 60. If such knocking occurs when trying to close the folding door, the door cannot be smoothly closed. Further, if a person hits the hanging door and knocks, the door may be damaged.

On the other hand, as a conventional hinge for connecting the hanging door of the folding door and the opening door, both the vanes are locked when the folding door is closed, that is, when the angles of the both vanes become 180 degrees. In addition, when the folding door is opened, that is, when the angle of both blades becomes 0 degree, the one that locks both blades is often used. As such a hinge, an advancing / retreating engaging member biased forward by a winding spring is attached to one of the vanes, and a protrusion engaging with the engaging member is provided on the other vane. The blade angle is 18
Many of them have a structure in which both the vane plates are locked by engaging the engaging member and the protrusion at 0 degree and 0 degree respectively.

However, in the conventional hinge for the folding door described above, when the folding door is opened and the hanging door and the opening door are parallel to each other, the door is locked in this state. The door could be prevented from opening and closing smoothly or the door might be damaged.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a hinge capable of preventing knocking of a folding door, smoothly opening and closing the door, and preventing damage to the door. To do.

[0009]

In order to achieve the above object, the present invention provides a pair of vane plates pivotally connected to each other, a cam member attached to one vane plate, and a base end side of the other vane plate. A leaf spring engaged with the cam member in a state of pressure contact with the blade member, and when the angle between the blade plates becomes 180 degrees due to the engagement of the leaf spring and the cam member. Both the vanes are locked, and when the angles of the vanes are less than 10 degrees, the vanes are opened so that the angle becomes 10 to 45 degrees, and then the vanes are locked. A hinge characterized by the above is provided.

In this case, if the angle at which both blades are opened and locked is less than 10 degrees, knocking may not be sufficiently prevented, and if it exceeds 45 degrees, the opening width when the door is locked becomes small. Sometimes. A more preferable range of the angle for opening and locking both blades is 15
-40 degrees.

In the present invention, the shape and structure of the cam member are not particularly limited, but when the angle of both blades is 180 degrees, the first flat surface portion presses against the leaf spring to lock both blades,
Open both blades so that the angle becomes 10 to 45 degrees when the angle of both blades is less than 10 degrees, and press them against the leaf spring when the angle of both blades is 10 to 45 degrees. The second plane portion that locks both blades with the first plane portion and the second plane portion.
A structure having a curved surface portion that is present between the flat surface portion and that rotates the blade plate in a state of being pressed against the leaf spring can be preferably used.

[0012]

When the hinge door of the folding door and the opening door are connected using the hinge of the present invention, the doors are not locked when they are parallel to each other, and the angle of both doors is 10 to 45 degrees. Open the door and lock it. Therefore, when the folding door is opened, there is an angle of 10 to 45 degrees between the hanging door and the opening door, so when a lateral or diagonal force is applied to the door,
The opening door slides smoothly between the upper and lower rails, preventing knocking. When it is necessary to extend the opening width by making the hanging door and the opening door parallel to each other, the opening door may be pushed toward the hanging door.

Further, in the hinge of the present invention, since the door rotates while the plate spring is in pressure contact with the cam member, a frictional force is generated between the plate spring and the cam member when the door rotates. The frictional force prevents the door from rapidly rotating when the folding door is opened and closed. In this respect also, the folding door is prevented from being damaged, and the opening and closing of the folding door gives a feeling of weight, giving a sense of quality. . That is, the conventional hinge for a folding door locks the door by engaging the engaging member biased by the coil spring with the protrusion, and the engaging member and the protrusion are pressed against each other when the door is rotated. Since it does not, the door may suddenly rotate when opening and closing the folding door, and the feeling of weight when opening and closing the folding door is poor, but the hinge of the present invention has such drawbacks of the conventional hinge. Has been resolved.
