Description

[Detailed description of the invention]

[0001]

The present invention relates to a door for furniture and the like in which a door can be opened and closed within a range of 180 ° by combining a cam plate and a link assembly member, and at the same time, a hinge itself is not projected outside. It's about hidden hinges.

[0002]

2. Description of the Related Art Conventionally, as a solution to the inconvenience that the opening of a door is limited by an adjacent furniture door and the door cannot be opened sufficiently, the door is provided movably in the front-rear direction at a door of a furniture main body. A door holding member in which a door is hinged to the door, and the door holding member is pivotally mounted on the door holding member so as to be rotatable in conjunction with the opening and closing of the door. There is known a hinge device for a door in furniture including a driving member which makes the door holding member propelled (see Japanese Patent Application Laid-Open No. 60-219379).

[0003]

However, in the above prior art, a door holding member having a complicated structure and a driving member (for example, a pulley, a belt, a rack, a pinion, etc.) for driving the door holding member are required. In addition, since the support shaft that supports the towing, which replaces the hinge that opens and closes the door, supports the entire door, there was a problem in strength as a support shaft that can be used in a limited space. . In view of this point, the present invention can achieve a smooth opening and closing of the door and a sufficient opening degree by combining a link plate and a cam plate with a simple structure and a rigid plate material in terms of strength. An object of the present invention is to provide a hidden hinge of a door in furniture or the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a base plate is fixed to an appropriate position on an opening side of a furniture main body in a hidden hinge of a door in furniture or the like, and a cam is provided. A plate is fixed to one end of the door, and a first arm is attached to the base plate with a first caulking shaft.
Attach the second arm with the caulking shaft, and the other end of the first arm
Part and the end of the substantially L-shaped first lever, and the second
The other end of the arm and the middle of the first lever,
One end of a substantially L-shaped second lever at an intermediate portion of the second arm
And the other end of the first lever has a third arm.
While being pivotally connected to one end, the cam groove of the cam plate
A second pin is provided for engagement, and the other end of the second lever is
A technical means of pivotally connecting the other end of the third arm to one end of the cam plate and forming the third arm is adopted.

[0005]

The present invention adopts the above technical means so that the door can be propelled forward while rotating in accordance with the opening and closing of the door by the link assembly member. By moving the pins along the door, the door can be opened to the full front of the adjacent furniture, and furthermore, the operation is performed continuously and the opening and closing operation can be performed smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a schematic perspective view showing a storage having a pivotable opening / closing door whose end is supported by a hinge, which is an embodiment, wherein A is a storage main body, 2 is a door, and 12 is a top of the main body. Board,
13 is a main body side plate. Next, an embodiment of a hidden hinge for opening and closing the door 2 with respect to the main body side plate 13 will be described with reference to FIGS.
This will be described in detail with reference to FIG. What is shown in FIG.
Exploded perspective view showing each member of the hidden hinge of the present invention in an exploded manner,
FIG. 3 is a schematic assembly perspective view showing these components assembled. The base plate 1, the first arm 6, the second arm 8, the third arm 11, the first caulking shaft 5, the second caulking shaft 7, and the third Caulking shaft 14, fourth caulking shaft 16, fifth caulking shaft 17, sixth caulking shaft 21, first pin 15, second pin 1.
8, a first lever 9 made of a substantially L-shaped plate, a second lever 10 made of a substantially L-shaped plate, and a cam plate 4, which are hinged in the following combination. The first arm 6 and the second arm 8 are rotatably attached to the base plate 1 by the first caulking shaft 5 and the second caulking shaft 7 with respect to the base plate 1 fixed to the main body top plate 12. The other end of the arm 6 opposite to the end attached to the base plate 1 is rotatably attached to one end of the first lever 9 with the third caulking shaft 14, and the second
Similarly, the arm 8 is rotatably attached to the middle of the first lever 9 with the first pin 15, and one end of the second lever 10 is freely rotatable at the middle of the second arm 8 with the fourth caulking shaft 16. The first lever 9 is made of a substantially L-shaped plate, and is provided at one end of a third arm 11 at an end opposite to the end rotatably attached to the first arm 6. The fifth
The third arm 1 is rotatably mounted on a caulking shaft 17.
The other end of the third arm 11 is pivoted at the end opposite to the end of the second lever 10 made of a substantially L-shaped plate at the other end of the first lever 8 and rotatably attached to the second arm 8. Attach freely,
This other end is further rotatably attached to one end of the cam plate 4 by a sixth caulking shaft 21. And
A cam groove 19 is formed in the cam plate 4, and a second pin 18 fixed to the other end of the first lever 9 is engaged with the cam groove 19. And
The cam plate 4 is fixed to the door 2. FIG. 4 shows the hinge according to the embodiment of the present invention described above, specifically attached to the opening 3 and the door 2 of the storage body.
6A and 6B, the one shown in FIG. 4 shows a closed state, and the one shown in FIG. 5 shows an opened state. A first arm 6 and a second arm 8 rotatably attached to the base plate 1, and a first lever 9 and a second lever rotatably attached to the first and second arms 6 and 8.
The lever 10 and the third arm 11 rotatably attached to the first and second levers 9 and 10 perform a linking operation. With this linking operation, the door 2 is moved forward from the closed state shown in FIG. The door can be opened by pivoting to the side, and as shown in FIG.
When the levers 9 and 10 advance forward, protrude from the door of the adjacent storage main body, and further rotate the door 2, the second pin 18 moves with the cam groove 19 of the cam plate 4 as a guide. Numeral 2 is rotated by 180 ° to open the door as shown. The one shown in FIG.
FIG. 3 is a cross-sectional view taken along the line XX of FIG. 1, showing a state in which the hinge of the present invention is attached to the main body of the storage. In this embodiment, the hinge attached to the main body top plate 12 is shown. Needless to say, it can be attached. Numeral 20 denotes a top plate upper reinforcing plate, which is for aesthetics when opened and closed, and for protecting items when articles are taken in and out. Base plate 1, cam plate 4, first arm 6, second arm 8,
The third arm 11, the first lever 9, and the second lever 10 are formed of a plate material such as a stainless steel plate or a brass plate, and the shape of each member forming the link means can be variously designed. For example, the first lever 9 and the second lever 10 are substantially L
Not only the letter shape, but also the arc shape, the letter shape, etc.
The arm 6 and the second arm 8 are not limited to the Y-shape, but may be formed by simply bending a plate material, and the shape of the cam plate 4 and the shape of the cam groove 19 may be such that the door 2 can be opened and closed by 180 °. Needless to say, various changes can be made.

[0007]

According to the present invention, the following effects can be obtained based on the above configuration. (1) By the combination of the link assembly member and the cam plate, the opening of the door can be opened by 180 ° without being restricted by the door of the adjacent furniture. (2) Since the link member and the cam are formed from the plate material,
It is most suitable as a hidden hinge, and also functions well as supporting a heavy door in terms of strength.
