Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for an adjuster device that can be mounted on a key part on the bottom surface of furniture such as a desk or a partition, and can adjust a horizontal level at the time of installation.

[0002]

[Prior art]

 Conventional adjuster devices for adjusting the horizontal level in furniture and the like generally have a structure in which the adjuster bolt is directly screwed onto the bottom surface by welding a nut to the bottom plate of the body of the furniture or the like. This conventional adjuster device requires a lot of (four or more) adjuster bolts to be screwed onto the bottom surface of the furniture when assembling the furniture, which is troublesome to mount. In order to save this mounting work, as described in Japanese Utility Model Publication No. Sho 54-67050, an adjuster device has been proposed in which an adjuster receiving member in which an adjuster bolt is screwed in advance is fitted to the furniture bottom surface. .

[0003]

[Problems to be solved by the device]

 However, in the conventional adjuster device described above, it is difficult to say that the adjuster is securely fixed because it is installed by only inserting the mounting portion standing on the upper surface of the adjuster receiver into the hole in the bottom bottom surface of furniture or the like. , There is a risk that the adjuster device may fall out when it is lifted by moving furniture. Furthermore, when furniture is moved, there is a possibility that household equipment may be dragged and a force other than vertical load may be applied to the adjuster. In view of the above problems of the conventional technology, the present invention is an adjuster device that can be mounted with one touch and has sufficient strength against forces in all directions applied when moving furniture. The purpose is to provide a mounting structure.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an adjuster device for adjusting the horizontal level of furniture or the like, which includes an adjuster receiver attached to the bottom surface of furniture and an adjuster screwed to the adjuster receiver and provided with a grounding board. In the mounting structure for mounting, the adjuster receiver includes a mounting base, an upper boss portion protruding upward from substantially the center of the mounting base, and a female screw drilled in the upper boss portion and screwed into the adjuster. A boss provided on the bottom surface of furniture or the like having a hole and a plurality of projecting pieces standing upright around the upper boss portion of the mounting base, and at least two of the projecting pieces having locking pieces for preventing slippage. By inserting the upper boss portion and the projecting piece into the projecting hole and the projecting hole, the locking pieces of the at least two projecting pieces are locked in the projecting hole. It is characterized in that.

[0005]

[Action]

 According to the present invention, the adjuster receiver is attached with one touch by simply fitting the upper boss portion and the projecting piece into the corresponding holes provided on the bottom surface of furniture or the like, and once attached, at least two of them are attached. The locking piece of the projecting piece is locked by the hole for the projecting piece and prevented from coming off, and the upper boss portion is provided in addition to the projecting piece, which also fits into the hole of furniture, etc. It is possible to maintain high strength that can withstand forces other than vertical load.

【Example】

 FIG. 7 is a front view of a desk (1) having the adjuster device (A) of the present invention attached to the bottom surface (1a). FIG. 6 shows an enlarged vertical section near the adjuster device (A), and FIG. 5 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 the desk (1) (see FIG. 4) and an adjuster receiving member screwed from below. It consists of a caster (3).

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

As shown in FIG. 1, the adjuster receiver (2) includes a substantially horizontal mounting base (4). An upper boss portion (4a) is provided on the upper surface of the center of the mounting base (4), and a lower boss portion (4b) is also provided on the lower surface of the center. These boss portions (4a), (4b) are aligned 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) has a length corresponding to the depth of the recess (7) of the adjuster (3) described above, and the outer diameter thereof can be fitted into the recess (7). . In addition, the length of the female screw hole (8) corresponds to the length of the male screw part (6a) of the adjuster bolt (6), and when the adjuster (3) is fully screwed in, the lower boss part The (4b) is completely housed in the recess (7), and the male screw part (6a) is screwed over the entire length of the female screw hole (8) to have a sufficient strength to withstand horizontal stress. ing.

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 portion (4a). Also, the retaining projections (10) and (10a) shown in detail in the perspective view of FIG. It is located at a different position. It is preferable that the projecting piece (10) and the projecting piece (10a) have different sizes.

These protrusions (9), (10), (10a) have the upper boss portion (4a) inserted into the hole (11) on the bottom surface (1a) of the desk (1) shown in FIG. They are simultaneously inserted into the holes (16), (17) and (17a) formed in the bottom surface (1a).

It is assumed that the retaining projections (10) and (10a) have a shape as shown in FIG. 2 and are integrally formed when the mounting base (4) is integrally molded with a synthetic resin. The IIIa-II Ia line cross section and the IIIb-IIIb line cross section of this FIG. 2 are shown in FIG. 3 (a) and (b), respectively. That is, a pair of peripheral upright portions (14) facing each other rise from the upper surface of the mounting base member (2) and are fused to the truncated cone-shaped top portion (12). There are two locking pieces (13) that are slightly outwardly opened downward from the truncated cone-shaped top (12) and are offset by 90 degrees from these peripheral uprights (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 (16), (17) and (17a) of the bottom surface (10a) of the desk (1), these locking pieces (13) are inward. When the lower end of the locking piece (13) finally comes out of the plate, it is pushed back to the outside by elastic force, and it locks as a stopper.

[0014]

[Effect of device]

 The present invention is configured as described above, and a plurality of projecting pieces are erected on the upper surface of the center of the adjuster receiving part and around the upper boss part, and at least two of these projecting pieces are formed with engaging pieces, and furniture is Since the structure is such that it is installed by inserting it into the hole for the upper boss part and the hole for the projecting piece on the bottom surface of the adjuster, and attaching it by engaging the locking piece, the mounting base of the adjuster receiver is the hole of the upper boss part. By inserting it into the bottom of furniture, etc., it can be attached easily and stably at a predetermined position with one touch as it cannot be removed. Therefore, by screwing the adjuster into the adjuster receiving portion in advance, the work for installing the adjuster at the time of assembling furniture or the like can be simplified.
