Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjuster device which is attached to a key portion of a bottom surface of furniture such as a desk or a partition to adjust a horizontal level at the time of installation.

[0002]

2. Description of the Related Art This type of adjuster device not only adjusts furniture up and down, but also receives the weight of the furniture, etc., and if it drags when moving it, horizontal force is applied to it. The strength that can withstand is also required. Further, as a matter of course, the female screw hole into which the male screw portion of the adjuster is screwed needs to have an appropriate length corresponding to the adjuster function. For this reason, this type of adjuster device is assumed to be composed of a screw-in type adjuster and an adjuster receiver, which is attached to the bottom surface of furniture or the like.
An example of this is described in Japanese Utility Model Publication No. 54-67050.

[0003]

In the above-described conventional adjuster device, the distance between the bottom of the furniture and the installation floor becomes large even when the adjuster is screwed all the way in,
It looks bad. Further, due to the structure, there is still a possibility that the attachment portion inserted into the bottom surface of the furniture may be damaged by the force applied between the furniture and the adjuster device when the furniture is dragged. An object of the present invention is to provide an adjuster device for adjusting the horizontal level of furniture or the like which solves the above problems.

[0004]

In order to achieve the above-mentioned object, the present invention is a furniture comprising an adjuster receiving member mounted on the bottom surface of furniture and the like, and an adjuster equipped with a grounding plate which is adjustably screwed to the adjuster receiving member. In the adjuster device for adjusting a horizontal level such as the above, the adjuster receiver has the mounting base, an upper boss portion protruding upward from substantially the center of the mounting base, and a lower portion of the mounting base member aligned with the upper boss portion. Lower boss portion and a female screw hole in the up-down direction that penetrates these boss portions, and the adjuster has an annular recess having a diameter larger than that of the lower boss portion protruding downward in the center of the upper surface of the grounding board. And a male screw portion which is erected at the center of the annular recess and is screwed into the female screw hole.

[0005]

According to the present invention, due to the presence of the upper and lower boss portions in the adjuster receiver, the male screw portion of the adjuster can be stabilized and can be moved up and down with a sufficiently long stroke, and the distance between the furniture bottom surface and the installation floor surface can be increased. It can be made small and can have sufficient strength against a horizontal force.

FIG. 6 is a bottom view of the adjuster device (A) of the present invention.
It is a front view of the desk (1) attached to (1a). FIG. 5 shows an enlarged vertical section near the adjuster device (A), and FIG. 4 shows a bottom view of the same. Details of the adjuster device (A) are shown in FIG. 1 as an exploded vertical sectional view.

As can be easily seen from FIG. 1, the adjuster device (A) includes an adjuster receiving member (2) attached to a bottom surface (1a) of a desk (1) and an adjuster screwed from below.
It consists of (3).

The adjuster (3) is formed by embedding a metal adjuster bolt (6) in a ground plate (5) made of synthetic resin, for example. The grounding plate (5) should be installed around the male thread (6a) of the adjuster bolt (6).
A deep and wide annular recess reaching the back of the head (6b) of (6)
It has (7). It is preferable that the bottom surface of the grounding board (5) be uneven as shown in FIG. 4 and the side surface be serrated as shown in FIG.

As shown in FIG. 1, the adjuster receiver (2) includes a mounting base (4) which is substantially horizontal. On the upper surface of the center of the mounting base (4), the upper boss (4a) is
Similarly, lower boss portions (4b) are provided on the lower surface of the center, respectively. These boss portions (4a), (4b) are in alignment with each other, and a female screw hole (8) to be screwed into the male screw portion (6a) of the adjuster bolt (6) is formed at the center thereof.

The lower boss portion (4b) is the adjuster described above.
It has a length corresponding to the depth of the recess (7) of (3), and its outer diameter can be fitted into the recess (7). The length of the female screw hole (8) is the same as the male screw part of the adjuster bolt (6).
Adjuster (3) is said to be commensurate with the length of (6a).
When fully screwed in, the lower boss portion (4b) is completely housed in the recess (7), and the male screw portion (6a) is screwed over the entire length of the female screw hole (8) with sufficient strength. It is designed to withstand horizontal stress.

On the upper surface of the mounting base (4), the cylindrical positioning projections (9) shown in FIG. 1 are arranged one on each side of the upper boss (4a) as shown in FIG. It is set up. In addition, the protrusions (10) and (10a) for retaining which are shown in detail in the perspective view of FIG.
Also, one on each side of the upper boss (4a), and the protrusion (9) is 9
It is arranged at a position shifted by 0 degree. As shown in FIG.
It is preferable that the projecting piece (10) and the projecting piece (10a) have different sizes. These protrusions (9), (10), (10a) are, when the upper boss portion (4a) is inserted into the hole (11) on the bottom surface (1a) of the desk (1),
It is to be inserted into the holes (not shown) on each bottom surface (1a) in alignment with each other.

The retaining projections (10), (10a) are integrally formed in the shape shown in FIG. 2 when the mounting base (4) is integrally molded with synthetic resin. That is, a pair of peripheral upright portions facing each other from the upper surface of the mounting base (4).
(14) rises upward and merges with the truncated cone-shaped top (12). Two locking pieces (13) opened slightly outward from the truncated cone-shaped top portion (12) are formed so as to be offset by 90 degrees from these peripheral upright portions (14). This locking piece (13) does not reach the upper surface of the mounting base (4) and leaves a gap just by the plate thickness of the bottom surface (1a) of the desk (1). Therefore, when the protruding pieces (10) and (10a) are inserted into the holes on the bottom surface (10a) of the desk (1), these locking pieces are inserted.
When (13) is pushed inward and slightly squeezed into it, and finally the lower end of the locking piece (13) comes out of the plate, it will return to the outside due to the elastic force and prevent it from coming off. .

[0013]

As described above, according to the present invention, a female screw hole is formed in a vertically protruding boss portion in the center of the mounting base of the adjuster receiver, and the male screw portion of the adjuster is screwed into the female screw hole. Therefore, the adjuster receiver has sufficient strength and is not easily damaged by the force applied to the adjuster. In addition, a recess is formed in the center of the upper surface of the grounding plate of the adjuster, and a male screw portion is provided upright in the center, so that the height of the lower boss portion of the adjuster receiving portion is absorbed by this recess. It is possible to reduce the size from the adjuster to the grounding board, and the overall appearance of furniture and the like can be maintained.
