DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge for opening and closing a door to a main body of a cabinet or the like, and more particularly, to a so-called slide hinge whose axis of rotation is shifted in a horizontal plane when the door is opened and closed. is there.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 7 and 8, a hinge 60 of this type is embedded in a door 4 and fixed to a side plate 50 of a cabinet. A frame portion 66 is integrally connected to the shaft 60 via a plurality of links 62 and a shaft pin 64, and is detachably attached to the washer 61 by a screw fixing type or a one-touch type by snap engagement.

[0003] By the way, in the case of assembled furniture, a so-called knock-down system is adopted in order to facilitate shipping and packing in a factory and to improve handling in a distribution process. From the viewpoints of easiness and ease of parts management, it can be said that it is desirable that the metal fittings such as the hinges remain attached to the disassembled furniture as much as possible.

In this type of hinge, a washer 61 is fixed to a side plate 50 of the cabinet, and a cup 60 and a frame 66 are attached to the door 4 disassembled from the cabinet. Or a so-called washer-side attachment / detachment method in which the entire hinge is attached to the side plate 50 and a cup-side attachment / detachment method in which the cup portion 60 is screwed in accordance with the recessed portion of the door 4 during assembly.

[0005] In the washer-side detachable type, in the case of a one-touch engagement configuration, an assembling operation is easy, for example, a tool is not required. However, as shown in Fig. 9, a frame portion 66 protrudes from one end surface of the door 4. Therefore, in addition to the risk of damage to the frame portion 66, a plurality of doors cannot be placed in a stacked state such that the side surfaces are flush with each other, which makes the packaging cumbersome and increases the amount of packing materials (furthermore, industrial waste). Disadvantage).

On the other hand, the cup-side detachable method has an advantage that the doors can be stacked in a flush manner, but the work is difficult because a plurality of cup parts need to be pushed into each of the recesses of the door at the same time. It becomes even more difficult because the door must be closed and mounted), and screw fixing work using a tool is inevitable.

[0007] In view of the above situation, the cup-side attachment / detachment system, in which the doors can be stacked in a flush manner to facilitate the packing operation, is basically advantageous from the viewpoint of the knockdown system.

For this reason, for example, Japanese Utility Model Laid-Open No. 49-30770.
As shown in the publication, the cup portion is enlarged by a cam mechanism and fixed in the recessed portion.
As shown in Japanese Patent No. 29476, the cup portion has a double structure consisting of an outer cup fixed to the door and an inner cup attached to the frame side, and both cups are fixed by means such as screwing, or Further, a method has been proposed in which a cup portion is obliquely engaged with a seat fixed to a door, and is rotated and locked.

[0009]

According to the method described in Japanese Utility Model Application Laid-Open No. 56-129476,
This increases the number of parts and complicates the structure of the cup part, which inevitably increases the price. In addition, in the case of a method in which the frame portion is locked by being engaged obliquely, it cannot be mounted in a state where the frame portion is fixed to the side plate, and there is a disadvantage that the working mode is limited.

Accordingly, an object of the present invention is to provide a hinge of this type which can maintain the advantages of the cup-side detachable system in knockdown furniture, improve workability, diversify mounting forms, and reduce manufacturing costs. I do.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention focuses on the conventionally inseparable structure of a cup portion and a frame portion, and aims at practical use of the separated structure. The feature is that a plurality of shaft pins are separated from the cup portion and provided at the ends of a plurality of links of the frame portion, respectively, and the plurality of shaft pins are interconnected to each other. After receiving one shaft pin from the upper side in the depth direction of the cup portion and storing the same, a receiving groove is formed in which the frame portion is tilted to receive another shaft pin. A lock member is provided to prevent the shaft pin from moving after being housed.

Further, according to the present invention, the lock member can be configured as an insertion plug that is press-fitted into the recessed portion of the door to prevent the movement of the shaft pin.

[0013]

According to the present invention, for example, a knock-down type in which a cup portion is fixed in advance in a recessed portion of a door and a washer is fixed to a side plate of a cabinet. The assembling is such that after one shaft pin of the frame portion is received and received in the receiving groove of the cup portion from the upper surface in the depth direction of the cup portion, the frame portion is rotated about the one shaft pin as a fulcrum and tilted. And the other shaft pin are accommodated in the accommodation groove. Since the plurality of shaft pins are connected to each other, no displacement occurs in engagement with the housing groove, and movement of the shaft pin with respect to the cup portion is prevented by the lock member. Thus, the cup portion and the frame portion are connected to each other, and the function of rotating the door with respect to the cabinet is obtained by fixing the frame portion to the washer of the side plate.

[0014]

1 to 4 show an embodiment of the present invention.
The hinge 2 has a cup portion 8 embedded and fixed in the recessed portion 6 of the door 4, a frame portion 10 coupled to a washer fixed to a side plate of a main body such as a cabinet, an insertion plug 11 as a lock member, 11 are provided.

The cup portion 8 is provided with a cup body 12 housed in the recess 6 and a fixing piece 14 connected to the cup body 12. Receiving grooves 16 are formed. The cup body 12 is formed in a substantially rectangular shape,
Void portions 20, 20 are formed between the hollow portion 6 and the hollow recess 6 in the embedded state. Reference numeral 18 indicates a screw fixing hole.

The frame 10 has a frame body 22 fixed to a washer of a side plate by a screwing method or a one-touch engagement method, and a shaft 2 attached to a connection end of the frame body 22.
Outer link 26 pivotally mounted via 4
And an inner link 30 similarly rotatably mounted via a shaft 28. Shaft pins 32 and 34 are provided at the distal ends of the outer link 26 and the inner link 30, respectively. Each shaft pin 32, 34 is connected to a connecting piece 36, 36.
Are linked by Reference numeral 38 denotes a spring member for urging a catch force on the cup portion 8, and reference numerals 40 and 42 denote a supporting shaft and a receiving shaft of the spring 38, respectively. In the drawing,
The one-touch engagement structure of the frame portion 10 with the washer is omitted.

A recess 16a for accommodating the shaft pin 32 and a recess 16b for accommodating the shaft pin 34 are formed in the housing groove 16, and the upper surface in the depth direction of the cup is opened.

Next, the operation of assembling the hinge 2 will be described. As shown in FIG. 1 and FIG.
6a, and then, as shown in FIG. 3, the frame portion 1 with the shaft pin 32 housed in the recess 16a.
0 is rotated about the shaft pin 32, and the shaft pin 34 is housed in the recess 16b.

The shaft pins 32, 34 are respectively
The state of fitting to 16b is the same as the conventional case where the cup part and the frame part are integrated. That is, the receiving grooves 16, 16 of the present application can be formed by cutting out the cup portion of the conventional product. In a state where the shaft pins 32 and 34 are set at fixed positions, the upper protruding edge 16c of the accommodation groove 16 is provided.
As a result, upward pulling out in the same state is prevented.

Here, the shaft pin 3 associated with the opening / closing operation of the door 4
Considering the action of the forces on the cup body 12 of the first and second cups 34, when the outer link 26 and the inner link 30 move in the direction of the arrow S with respect to the cup portion 8, that is, when the door 4 is closed, The shaft pin 34 moves in the arrow N direction about the pin 32. Therefore, if the movement of the shaft pin 34 is prevented, the same hinge function as that of the related art can be obtained. Since the shaft pin 34 is merely a rotation axis of the inner link 30, the moving force of the inner link 30 in the direction of the arrow N of the shaft pin 34 is not large, and can be dealt with sufficiently by the presence of a so-called padding or the like. . The upward component force due to the moving force of the shaft pin 34 is even smaller. When the door 4 is opened, there is no problem because the shaft pins 32, 34 are completely received by the housing grooves 16, 16.

After the shaft pins 32, 34 are received in the receiving grooves 16, 16, the plugs 11, 11 are press-fitted into the gaps 20, 20, as shown in FIG. The insertion plug 11 has an insertion portion 11 a into the cup body 12 and shaft pins 32 and 3.
4 and the contact portion 1 with the fixing piece 14
1c is formed. The insertion portion 11a provides stable attachment to the cup body 12, and the contact portion 11c prevents the shaft pin 34 from shifting in the moving direction. Therefore, the shaft pins 32, 34 are held by the holding portion 11b so that the cup body 1
2 is fixed without trouble. This provides a hinge function. Note that the insertion plug 11 can be formed of a synthetic resin or the like. In FIG. 1, one of the plugs 11 is omitted.

In the above-described example, the attachment mode in which the frame portion 10 is held by hand is shown, but as shown in FIG.
The door 4 can be connected by moving the door 4 while being attached to the washer 52 fixed to zero.

In the above example, each component has a specific shape. However, the present invention is not limited to this, and the design can be changed as appropriate as long as the above-described mounting function can be achieved. For example, as shown in FIG. 6, the shaft pins 32 and 34 can be formed as a shaft pin 35 as a substantially U-shaped integral body. In this case, the manufacture of the shaft pin is easy, and the assembling work can be facilitated. In this case, the fixing function of the insertion plug 11 can be obtained in the same manner as in the above example.

[0024]

According to the present invention, in the case of a slide hinge in which the rotation axis is shifted in a horizontal plane, it is possible to adopt a knock-down configuration that does not have an inner cup when only the cup portion is attached to the door. In this case, it is possible to cope with the problem by improving the conventional cup portion and not to complicate the structure of the cup portion, so that the advantage of the cup-side detachable system can be obtained at low cost.

In particular, according to the present invention, the plurality of shaft pins provided on the plurality of links are connected to each other without being free, thereby preventing the falling off of the shaft pins and the occurrence of the displacement between the shaft pins. In addition, the engagement of the plurality of shaft pins into the accommodation grooves can be reliably performed.
