Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjuster device for adjusting the height of furniture such as desks, tables, partitions and cabinets.

[0002]

2. Description of the Related Art As a conventional adjuster device of this type, as disclosed in, for example, Japanese Patent Laid-Open No. 6-245832, a head of an adjuster bolt is embedded in the center of a disc-shaped leg seat to adjust the adjuster. The external thread of the bolt is screwed into a screw hole provided at the lower end of the furniture leg or the housing, and the leg seat and the adjuster bolt are rotated around their central axes to project from the lower end of those legs. It is common to change the amount so that the height of furniture can be adjusted.

[0003]

However, in the conventional adjuster device as described above, if the amount of protrusion of the adjuster bolt from the lower end of the furniture is large, the male screw portion of the adjuster bolt is exposed to the outside, which is unsightly.

Further, in most of the conventional products, the leg seat is made of a synthetic resin material and molded so that the head of the metal adjuster bolt is embedded in the foot seat. It is difficult to separate the leg seat and the adjuster bolt, which are parts made of different materials, at the time of disposal.

In view of the above-mentioned problems of the prior art, the present invention has a good appearance during use, the cover can be easily replaced according to the use situation, and different materials can be sorted at the time of disposal. The present invention aims to provide a furniture adjuster device.

[0006]

According to the present invention, the above problems can be solved as follows. (1) Furniture in which a male screw portion of an adjuster bolt projecting upward from the center of a disc-shaped leg seat is screwed into a vertically oriented screw hole provided at a lower end of furniture whose height is to be adjusted. In the adjuster device of No. 2, a truncated cone having a desired height is provided at a peripheral edge of an upper surface of the leg seat with a standing wall having an inward locking portion at an upper end, and a through hole through which the adjuster bolt penetrates at a center of the upper surface. A cover having a shape is placed on the leg seat, and an outward engaging projection provided on the lower end portion of the elastic engaging piece hanging from the lower end of the cover is attached to the lower edge of the engaging portion of the leg seat. Engage.

(2) In the above item (1), a recess is provided at the center of the lower surface of the leg seat, a head provided at one end of the male screw portion of the adjuster bolt is fitted in the recess, and the upper surface of the leg seat is fitted. In the center, a nut receiving part that non-rotatably fits a non-circular nut that is screwed with the male thread of the adjuster bolt is provided, and the leg seat is attached by the head of the adjuster bolt and the nut. Attaches to the seat as removable.

(3) In the above item (2), the head of the adjuster bolt is spherical, and the spherical head is in contact with the floor.

(4) In any one of the above items (1) to (3), a plurality of covers having different heights, colors and shapes are provided, and any one of them is selected and attached to or detached from a leg seat. Make it profitable.

[0010]

1 and 2 show an embodiment of the present invention. The adjuster device (1) includes a substantially disk-shaped leg seat (2) made of a hard synthetic resin material, and a large-diameter head (4) having a spherical lower surface at the lower end of a male screw part (3) facing up and down. ) Connected metal bolts (5), nuts (6) with hexagonal outline, and cover (7) with frusto-conical shape made of soft or slightly hard synthetic resin material. Has become.

At the center of the leg seat (2), an adjuster bolt
A through hole (8) into which the male screw part (3) of (5) is inserted is formed, and an adjuster bolt is provided at the center of the lower surface of the leg seat (2).
A circular recess (9) into which the head (4) of (5) fits is formed,
Further, an annular concave groove (10) for lightening is formed on the outer peripheral portion of the concave portion (9) on the lower surface thereof.

At the center of the upper surface of the leg seat (2), a nut receiving portion (11), which is a bottomed hexagonal hole that compliments the outer diameter of the nut (6), is formed. A standing wall (13) having an inward locking portion (12) at the upper end is formed at the peripheral edge of the upper surface of (2).

The cover (5) is formed with a through hole (14) at the center of the upper end through which the male screw part (3) of the adjuster bolt (5) is inserted, and at the outer peripheral edge of the lower end of the cover (5). Engagement protrusion
Short cylindrical elastic engagement pieces (16) having (15) are continuously provided so as to hang down. In this example, the elastic engagement piece (16) is provided on the entire outer periphery of the lower end of the cover (5).
It may be provided only at arbitrary plural places.

The adjuster bolt (5) has its head (4) fitted in the recess (9) of the leg seat (2), and has a male screw (3) through hole.
It is inserted into (8) and screwed into a nut (6) which is fitted into the nut receiving part (11) so as not to rotate relative to it. The nut (6) and the head (4) allow the leg seat (2 ) Is attached to the leg seat (2) so as to be detachable.

In the cover (5), the male screw part (3) of the adjuster bolt (5) has a through hole (14) from above the leg seat (2) to which the adjuster bolt (5) is fixed as described above. Covering so as to be inserted, and the engaging projection (15) of the elastic engaging piece (16),
It is detachably attached to the leg seat (2) by elastically engaging the lower edge of the locking portion (12) of the leg seat (2).

In this state, the male screw portion (3) of the adjuster bolt (5) is welded to the lower end portion of the leg (17) of the table (may be the lower end portion of other furniture) as shown in FIG. The nut (18) provided is screwed into the screw hole (19) directed in the up-down direction from below, and the lower surface of the leg seat (2) is brought into contact with the floor to support the leg (17).

In order to adjust the height of the legs (17), the adjuster bolt (5) together with the leg seat (2) is rotated around its axis to change the protrusion amount of the legs (17) from the lower ends. Just do it.

The depth of the recess (9) of the leg seat (2) is set to be substantially the same as or slightly smaller than the height of the head (4) of the adjuster bolt (5), and the spherical head (4). When the height is adjusted, the leg seat (2) and the adjuster bolt
(5) can be easily rotated.

3 and 4 show a modified example in which the length of the male screw part (3) of the adjuster bolt (5) and the height of the cover (7) are made different. In this way, by preparing multiple types of adjuster bolts (5) with different lengths and covers (7) with different heights, a standard from the floor surface to the lower end of the legs (17) can be obtained. It is possible to cope with all situations in which different heights are different, and to increase the protruding amount of the adjuster bolt (5) without exposing the male screw part (3) to the outside.

Also, prepare a plurality of kinds of covers (7) having different colors, outer shapes, patterns, etc., select one suitable for the situation from them, and attach it to the leg seat (2). If so, versatility is further enhanced.

[0021]

According to the first aspect of the present invention, the appearance of the upper part of the leg seat is good, and the cover can be easily attached / detached. Therefore, the cover can be easily replaced according to the use situation.

According to the second aspect of the present invention, the leg seat, the adjuster bolt, the nut, and the cover can be separated from each other, so that different materials can be separated at the time of disposal, which contributes to reducing the load on the environment. it can.

According to the third aspect of the present invention, when the height is adjusted, even if the load of the furniture is applied to the adjuster bolt, the leg seat and the adjuster bolt can be easily rotated with a light force.

According to the invention described in claim 4, it is possible to deal with the preference of the user, a wide range of usage situations, and the like.
