Description

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG. 1, the present invention comprises a mounting plate a fixed to the inner surface of a side panel of a cabinet, etc., which is fitted into a recess provided on the inner surface of a door, and then fixed with screws. The relevant force 1
It relates to a hinge formed by connecting a socket b for fixing the socket b with a plurality of arms C so as to be openable and closable.

Generally, this f1 mounting plate is composed of two members: a fixed side member a' fixed to a side plate of a cabinet, etc., and an HVS A-Aa" to which the arm C is connected, and As illustrated in FIGS. 2 and 3, it is composed of three parts 3 to which an adjusting part a'' is added, and as shown in the figure, the member a' is connected to the arm to the fixed side part ha'. Or vertical adjustment device d1 front and back adjustment device e1
The left and right adjustment device f allows the door to be adjusted up and down, back and forth, and left and right, respectively, so that the opening position τj of the door can be adjusted.

Conventionally, the above-mentioned left and right adjustment devices are as shown in Figures 2 and 3.
The one shown in the figure is known.

That is, the one shown in Fig. 2 has an adjustment screw f' screwed through the hole f' of the above-mentioned member a'', and its tip abuts against the fixed side member a'. It is.

However, according to the above-mentioned configuration, the reaction force caused by the adjustment screw f" is received by the fixed side member a',
Although the fixed side member a' and the adjustment screw f' are not completely connected, it is fine to move the member a'' upward in the figure, but if you want to adjust the movement downward, use the adjustment screw frr. After screwing the appropriate amount, it is necessary to press member a downward by hand to move it, which is cumbersome to operate.
It also has the disadvantage of being time consuming.

This drawback is avoided by the system shown in FIG. 3, in which a flange f'' is provided at the tip of an adjustment screw fW screwed into a screw hole f' of member a'' to adjust the force.

A groove a''' having a generally convex shape in cross section is opened at the front end and horizontally provided in the front end of the side member a'', and the flange arm f'' is slidably and rotatably engaged in the groove arm; By advancing and retracting the adjustment screw f' by spiral rotation, the adjustment side member a is moved through the flange f″′.
By applying a reaction force to "', the member a" is adjusted to move in one direction or downward in the figure.

However, according to the above-mentioned configuration, the "2 groove a" is a flat groove, and the "1 flange f"' that is engaged therein also has a flat disk shape, so the above member a" To set a large amount of movement adjustment, the groove m and the flange f/r
It is necessary to maintain a gap of suitable size between J and J.

1. Since the above-mentioned part U'a" is tilted using the right end in the figure as a fulcrum, and the left end side to which the arm is connected is adjusted by moving left and right, the above-mentioned adjustment screw f" is tilted. A gap for this purpose is essential.

Therefore, in the above-mentioned device, when the adjusting screw f'' is in the vertical position as in the illustrated example, due to the above-mentioned gap, the adjusting side member a'''
Naturally, a necessary evil rattling will occur between the screw and the adjustment screw f7, and this rattling will cause an error during adjustment, which not only makes the adjustment more troublesome, but also
There is a drawback that adjustment tends to be uncertain.

As a result of studies in view of the above-mentioned drawbacks of the conventional art, the present invention is a mounting plate, in which a fixed side member is provided with a spherical seat having a substantially spherical cross section, which is elongated in the front-rear direction, and whose Ai+ end is open. - The tip of the adjusting screw screwed into the force adjusting side part 4AVc is formed as a spherical joint part, and this is configured to be engaged with the spherical seat so as to rotate and slide, thereby connecting the fixed side member and the adjusting screw. The goal is to ensure that there is no wobbling no matter what state of adjustment it is in, so that horizontal adjustments can be made easily and accurately.
That is the purpose.

Hereinafter, the present invention will be described in detail based on the illustrated embodiment.The hinge of the present invention is shown in FIG.
..., and FIGS. 4 and 5 show the main part, the mounting plate.

1. In the illustrated example, the mounting plate includes a fixed side member 1 consisting of a member 1a that is fixed to a cabinet or the like, a member 1b that is vertically adjustable and supported by an adjustment screw 2, and the arm C. . It goes without saying that it may be formed in the shape of a moon.

In the illustrated example, the member 1a is fixed to a side plate 6 of a cabinet or the like with screws 4.4, and is located on the front side of a member 1b that is screwed onto the member 1a so as to be able to adjust its movement rNf in the vertical direction. A spherical seat 6 having a substantially spherical cross section is opened at its front end and extends in the front-rear direction, and a long window hole 7 having a constant narrow width over the entire length is provided above the spherical seat 6.

On the other hand, a screw hole 3 penetrating the front wall 3a of the adjustment side member 3
An adjustment screw 8 is threaded through b so that it can be screwed forward and backward in the left and right direction of the door (not shown), and the upper end of this adjustment screw 8 is connected to the threaded part 8a in the figure, and the lower end is connected to the threaded part 8a. ,
A spherical joint part 8b has the same curvature as the spherical seat 6, and a neck part 8C is formed between the threaded part 8a and the spherical joint part 8b, the diameter of which is smaller than that of the spherical joint part 8b. 8b is rotatably and slidably engaged with the spherical seat 6, so that the part 1b and the adjustment screw 8 are connected without any looseness in any direction.

Here, the width of the long window hole 7 connected to the upper side of the spherical seat 6 is, of course, smaller than the diameter of the spherical seat 6.
The diameter of the neck portion 8C of the adjustment screw 8 is slightly larger than that of the adjustment screw 8, so that the spherical joint portion 8b does not come off upward in the figure, and the neck portion 8C is not rigid in the length direction. This allows for smooth sliding in the front and back directions.

The spherical joint portion 8b can be fitted into the spherical seat 6 through an opening 6a provided at its front end.

Further, in the illustrated example, the adjustment side member 3 is formed in a transverse U-shape from a front wall 3a and upper and lower side walls 3c, 3c curved in parallel from both side edges of the front wall 3a.
The adjustment screw 10 is inserted into the rear end of the front wall 3a through a long hole 9 provided long in the front and back direction, and is screwed into the member 1b. By wearing it, you can adjust the movement in the front and back directions.

In the above configuration, the adjustment screw 8 is connected to the adjustment side member 3.
When it is screwed into the screw hole 3b, the spherical joint part 8b at the end is engaged with the spherical seat 6 and does not move, so the reaction force is supported by part +J'1b. By doing so, the adjustment side member 3 is moved upward in the figure.

When the adjusting screw 8 is turned in the opposite direction to that described above, the adjusting member 3 is moved downward.

As a result, the door is adjusted to move leftward or rightward via the adjustment member 3, the arm, and the socket.

The amount of movement adjustment described above is within the range of the effective length of the screw hole 3b and the threaded portion 8a of the adjustment screw 8, but the adjustment described above is performed with the adjustment screw 1o loosened, and the adjustment side member 3 , the front side part is moved vertically in the figure using the abutted end where the rear end is abutted against part #1b as a fulcrum, so the larger the adjustment amount, the more the adjustment screw 8 becomes Although it is inclined in the left-right direction in FIG. 4, the spherical joint portion 8b has no directionality with respect to the spherical seat 6, so
Can be tilted freely.

Therefore, no bending stress is applied to the spherical joint part 8b and the spherical seat 6, the screw hole 3b and the threaded part 8a of the adjustment screw 8, etc.
The adjustment screw 8 threads smoothly during adjustment.

As explained above, according to the hinge according to the present invention, in which a mounting plate and a socket are connected by a plurality of arms, the mounting plate has at least a fixed side member fixed to a cabinet or the like. 1 and an adjustment side member 3 connected to the arm, and the adjustment side member 3 has an adjustment screw 8 having a spherical joint portion 8b at the end, which can be freely advanced and retreated by screwing in the left and right direction of the door. On the other hand, on the fixed side member, a spherical seat 6 having a substantially spherical cross section is provided, which is long in the front-rear direction and has an open front end. , and the adjustment side member 3 is fixed to the fixed side member 1 so as to be adjustable in left and right movement by being slidably engaged with the spherical joint portion 8b relative to the spherical seat 6. is fitted with universal directionality, and by the screwing of the adjustment screw 8,
By tilting the adjustment side member 3 using its rear end as a fulcrum, the adjustment screw 8 is also tilted when adjusting the horizontal movement, but a gap is provided to allow the adjustment screw 8 to tilt. , since there is no need to hold it between the fixed side member 1 and the adjustment screw 8, the spherical seat 6 and the spherical joint part 8b can be tightly engaged, and the connection is made without rattling. Adjustment of the adjustment side member 3 in the left and right direction can be made accurate, and the adjustment screw 8 can be freely tilted by its spherical joint portion 8b following the left and right movement of the adjustment side member 3, so that movement adjustment is particularly easy. When the amount is large, the adjusting screw 8 can be screwed without applying unreasonable bending stress to the threaded portion or the connecting portion between the adjusting screw 8 and the fixed side member 1, as in the conventional example. Not only can adjustments be made smoothly and easily, but also problems such as damage to the above-mentioned parts caused by forcibly screwing the adjusting screw 8 can be eliminated.
