Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge device capable of widely opening a swingable door in furniture or a swingable door in a building with respect to a fixed body such as a furniture body or a building. Related to the improvement of.

[0002]

2. Description of the Related Art When attaching a door to a furniture such as a locker or a cabinet so that the door can be horizontally rotated through a hinge device, the open door does not interfere with people's walking or putting things in or out of the furniture. It is being done that the door can be opened wide up to about 180 °.

In this way, the door in furniture is
A conventional hinge device for opening up to about 0 ° is disclosed in Japanese Utility Model Publication 59-10301.
As described in Japanese Patent Publication No. JP-A-2003-138, it is composed of three link bodies, and one end of the first link body is movable back and forth along the depth direction of the furniture body with respect to the furniture body and is rotatable. While freely pivoted, the other end of the first link body is pivotally attached to the door, and one end of the second link body is pivotally attached to the furniture body, while the other end is between the one end and the other end of the second link body. The middle part of the first link body is pivotally connected to the middle part between the one end and the other end, and the one end of the third link body is pivotally connected to the other end of the second link while the third link is connected. The other end of the body is pivotally attached to the door.

In other words, this prior art is characterized by opening and closing the door.
The door is opened and rotated by rotating the first link with respect to the furniture main body and moving back and forth along the depth direction of the furniture main body, and rotating the second link and the third link in conjunction with this. The door is configured to move away from the furniture main body while approaching the furniture main body while closing and rotating.
It was designed so that it could be opened about 0 °.

[0005]

By the way, when the door is rotatably attached to the furniture main body by this conventional hinge device, the load of the door is mainly the first of the three link bodies.
It will be supported by the link body. However, in addition to the one end of the first link body being pivotally attached to the furniture main body, the first link body will largely project to the front of the furniture main body when the door is opened, Since the first link body supports the load of the door in the state of a cantilever whose one end is attached to the furniture main body, the load of the door is not attached to the pivotal attachment point between the first link body and the furniture main body. It acts intensively as a large moment, and for this reason,
Not only the one end of the first link body and the part of the furniture main body to which the first link body is pivotally attached are easily deformed to have low support strength for the door, but also the first link body and the second and third link bodies interlocked with the first link body are twisted. However, there is a problem that the door is not opened and closed smoothly.

It is an object of the present invention to provide a hinge device which can improve the support strength of the door and can open and close the door very smoothly and greatly.

[0007]

In order to achieve this object, the present invention relates to a slide body that can move forward and backward along the depth direction of the fixed main body with respect to an opening in the fixed main body such as a furniture main body. And a pivoting body that can be moved back and forth in the same direction as that of the body, and the pivoting portion for the pivoting door that closes the opening of the fixed body is provided at the tip of the slide body and the tip of the pivoting body. And the slide body and the rotating body are interlocked by a link mechanism having one end pivotally attached to the fixed body, and the interlocking relationship between the slide body and the rotating body by the link mechanism. Is configured so that the pivoting body is advanced and retracted more than the slide body so that the pivoting portion at the tip of the pivoting body moves forward and backward and rotates around the pivotal attachment portion at the tip of the slide body.

[0008]

According to this structure, when the door is opened / closed, the slide body projects toward the outside of the fixed body, and at the same time, the rotary body moves in synchronization with the projecting movement of the slide body. The pivoting portion of the pivoting body with respect to the door overtakes the pivoting portion of the slide body with respect to the door, and thus the pivoting portion of the pivoting body with respect to the door pivots at a faster speed than the fixed body. However, it will rotate largely around the axis of the pivotally attached part with respect to the slide body for the door.

That is, the door rotates while being separated from the fixed main body as a whole, so that the door can be widely opened. And, in the hinge device, the load of the door is mainly supported by the slide body. In that case, since the slide body only needs to be attached to a fixed body such as a furniture body so as to be movable back and forth, for example, the slide body is provided at a plurality of locations in the furniture. The load of the door can be supported in a wide area of the slide body and the fixed body by supporting the slide body by the main body or the guide member having a long length.

Therefore, according to the present invention, since the load of the door can be supported by the large area of the slide body and the fixed body, deformation of the slide body and the portion of the fixed body to which the slide body is attached is prevented, and the support strength of the door is significantly improved. In addition, since it is possible to prevent the excessive load from concentrating on a specific portion of the slide body and the fixed body, it is possible to ensure a smooth operation of the slide body, so that the slide body or the rotating body can be secured. Also, it is possible to prevent the operation of the link body from being twisted and to open and close the door smoothly.

The pin 17 is configured to be rotatable.

The rotating body 9 has a torsion spring 18 whose one end engages with a hole 18a formed in the slide body 8 and a protrusion 18b.
Thus, the cabinet body 1 is biased to rotate in the outer surface direction. The link body 10 is a slide body 8
Between the base plate 11 and the base plate 11, and a substantially middle portion along the longitudinal direction of the link body 10 is rotatably attached to the slide body 8 by a pivot pin 19. The long groove hole 10a formed by cutting out at one end is rotatably locked to the second pin 20 fixed to the base plate 11, and the base end portion of the rotating body 9 is inserted in the long groove hole 10b formed by cutting out at the other end. By inserting the tip end of the first pin 17 provided in the above, the slide body 8 and the rotating body 9 are configured to move forward and backward in cooperation with each other.

By forming a fan-shaped hole 21 in a plan view in the base plate 11 and bending the link body 10 in a stepwise manner so that a portion other than one end of the link body 10 fits into the hole 21. The case 7 can be thinned by the thickness of the base body 11. The slide body 8
The tip of the cabinet and the tip of the rotating body 9 are
Is formed in a narrow width so as to extend toward the side of
The door 2 is attached to the tip of the slide body 8 and the tip of the rotating body 9.
Pin holes 22 and 23 are formed as an example of the pivotally connecting portion for the.

A bracket 25, which is L-shaped in a side view, is attached to the inner surfaces of the upper and lower ends of one side edge (right side edge in the embodiment) of the door 2 with a reinforcing member 24 having a U-shaped cross section in side view. Fixed at the horizontal piece 25a of the bracket 25
A support pin 27 having a large diameter portion 27a, and a locking pin 28
Are fixed by caulking so that the support pin 27 is located near the outer surface of the door 2, and the support pin 27 is inserted into the pin hole 22 at the tip of the slide body 8, while the locking pin 28 is rotated. It is inserted into the pin hole 23 at the tip of the moving body 9.

At this time, the vertical height dimension H of the large diameter portion 27a of the support pin 27 is set to be larger than the plate thickness dimension t of the rotating body 9, while the tip end portion of the rotating body 9 is attached to the door 2. It is formed in a stepped shape so as to be substantially in contact with the upper and lower end surfaces, and a gap e is formed between the tip of the rotating body 9 and the slide body 8.
Is formed, the engagement state between the locking pin 28 and the pin hole 23 is reliably maintained.

A back plate 2a is stretched on the back surface of the door 2. The maximum advance / retreat distance L0 of the slide body 8 is the length dimension S1 of the first elongated hole 13 formed in the slide body 8.
The length dimension S1 of the first elongated hole 13 is defined by
Is set to a size larger than twice the size L3 between the axial center of the support pin 27 and the outer surface of the door 2 at the tip of the slide body 8.

Further, since the rotating body 9 moves back and forth relative to the slide body 8, the maximum forward / backward distance L4 of the rotating body 9 is set.
Is the length dimension S1 of the first elongated hole 13 in the slide body 8.
And the length dimension S2 of the second elongated hole 16 are added together (S1 + S2). The length dimension S2 of the second elongated hole 16 is defined as the front-rear spacing between the support pin 27 and the locking pin 28. While being set to about twice the dimension P, the distance dimension L1 between the second pin 20 and the pivot pin 19, the first pin 17 and the second pin 2 are set.
The ratio of 0 to the space dimension L2 is L0 to (L0 + 2P)
Set to the relationship.

In the above structure, when the door 2 is pulled toward the front, the slide body 8 projects and the rotating body 9 also projects at a speed higher than that of the slide body 8. Thus, the door 2 as a whole projects in front of the cabinet body 1 and rotates counterclockwise in plan view. Then, the rotating body 9
The maximum forward / backward distance L4 of the slide body 8 is the maximum forward / backward distance L of the slide body 8.
0 is a dimension (2P) which is twice the front-rear spacing dimension P between the support pin 27 and the locking pin 28.
When the locking pin 28 overtakes the support pin 27 by the projecting movement of the support pin 27, the front-rear positional relationship between the support pin 27 and the locking pin 28 can be set to a position opposite to the front-back positional relationship in the closed state. Therefore, the door 2 can be opened greatly up to about 180 °.

The load of the door 2 is mainly supported by the slide body 8 of the hinge device 3 located below, and it is sufficient if the slide body 8 can be moved only back and forth. 3 guide pins 1 like
4 or can be supported by a linearly extending guide member, so that the load of the door 2 can be supported by a wide area of the slide body 8, the base body 11 and the cabinet body 1. Therefore, the support strength of the door 2 can be remarkably improved, and since the load can be prevented from concentrating on a narrow portion of the slide body 8, the smooth operation of the slide body 8 can be ensured. It is possible to prevent the twisting and to open and close the door 2 smoothly.

As in this embodiment, when the maximum advance / retreat distance L0 of the slide body 8 is set to a dimension larger than twice the dimension L3 between the axial center of the support pin 27 and the outer surface of the door 2, it opens. Since the outer surface of the door 2 in the state is located outside the outer surface of the door 2 in the closed state, even if the cabinets 1 are arranged side by side, the doors 2 in any cabinet 1 are adjacent to each other. It can be opened so as to overlap the outer surface of the door 2 in the cabinet 1.

Further, as in the above embodiment, when the spring 18 for urging the rotating body 9 to rotate toward the side of the cabinet body 1 is provided, the spring force of this spring 18 causes the door 2 to move. Urging the door 2 in the closing direction while opening up to about 90 °, and urging the door 2 in the opening direction when opening the door 2 by 90 ° or more. And 1
Since the door 2 is selectively urged in the opening direction, the door 2 can be prevented from being left in the half-opened state.

In the above embodiment, the locking pin 28 of the rotating body 8 is used.
Was configured to rotate counterclockwise around the support pin 27 in a plan view.
In the upper hinge device 3, the rotating body 9 is placed on the upper surface of the slide body 8, and the lower hinge device 3 is replaced by the upper and lower positions.
In FIG. 1, when the rotating body 9 is arranged on the lower surface of the slide body 8, the tip of the rotating body 9 and the support pin 28 do not interfere with each other regardless of which direction the rotating body 9 rotates.
As indicated by the solid line and the alternate long and short dash line in FIG. 1, the door 2 can be opened approximately 180 ° by rotating the rotating body 9 in either a counterclockwise direction or a clockwise direction in a plan view.

The hinge device 3 according to the present invention can be applied not only to the installation of a horizontally pivoting door, but also to the left and right side plates 1a of the cabinet body 1 as shown in FIG. It goes without saying that the present invention can also be applied to the case of being rotatable. Further, the slide body, the rotating body, and the link body may be directly attached to the furniture body without being attached via the case, and further, the pivots provided at the tip of the slide body and the tip of the rotating body may be installed. The attachment portion may have another form such as a pin protruding.

Further, the link mechanism is not limited to one link body, but may be formed by pivotally attaching a plurality of link bodies. It goes without saying that the present invention can be applied not only to the case where the door is attached to the cabinet, but also to the case where the rotatable door is attached to other furniture or the case where the door is attached to the building.
