[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a height adjusting device for adjusting the height of furniture such as a unit cabinet or the like so as to eliminate inclination in front, rear, left and right.

[0002]

2. Description of the Related Art In the case of supporting a lower surface of a unit furniture or the like so as to be adjustable in height, a prior art Japanese Utility Model Publication No. 63-13726 discloses a plurality of adjuster bases mounted on a ground rail fixed to a floor in a plan view frame shape. The table is slidably mounted, and an adjuster bolt is erected only on each adjuster base so that it can only rotate, and a support plate is screwed to the adjuster bolt so as to be vertically movable, and a baseboard is mounted on the support plate. It is proposed that the furniture be placed on top of it and the lower end of the furniture be placed on it.

[0003]

According to this prior art, when a plurality of unit furniture and the like are arranged side by side, a plurality of adjuster bases are arranged at appropriate intervals on the ground rail extending in the direction of the arrangement. By rotating each of the adjuster bolts, the height of the baseboard is adjusted so as to be horizontal in front, rear, left and right.

In this case, if the left and right installation positions of the adjuster base with respect to the ground rail are shifted, the horizontal state of the baseboard will be disrupted. In addition, if the distance between the adjuster base and the ground rail is large or small, heavy furniture cannot be evenly supported, and in severe cases, the furniture may be inclined or fall. Therefore, it is necessary to set the installation interval of the adjuster base of the prior art at a predetermined interval, and there is a problem that the installation work of the furniture is extremely troublesome.

It is an object of the present invention to solve the problems of the prior art and to provide a height adjusting device which can be easily assembled.

[0006]

In order to achieve the above object, the present invention is to adjust the height of a baseboard for supporting a lower end of furniture with an adjuster bolt of adjuster means located on a lower surface side of a base body. In the furniture height adjusting device configured as described above, a downwardly open base that extends vertically along the front edge of the furniture is fitted to the edge of the base body in a vertically movable manner. The part is formed so as to extend in the frontage direction of the furniture, and the adjacent base bodies are connected to each other along the frontage direction of the furniture via a support that fits below the fitted portion. A notch groove is formed in an upper end face of the fitted portion so that an adjuster bolt screwed up and down to the upper piece of the support can be inserted upward.

[0007]

According to the above construction, when the support to which the adjuster bolt is attached is inserted below the downwardly open fitting portion of the base body from the side of the fitting portion,
The side surface of the adjuster bolt shaft portion comes into contact with the notch groove formed in the upper end surface of the fitted portion, so that the installation position of the adjuster bolt, and eventually the position of the support, are automatically determined. Then, when connecting furniture in the lateral direction, when the adjacent base bodies are abutted so that the fitting portions are adjacent to each other, the support is straddled below the fitting portions so as to be fitted and arranged. As a result, the displacement of the base body itself is eliminated, and the position of the adjuster bolt is also prevented from being displaced by being sandwiched between the notched grooves of both the fitted portions.
As described above, according to the present invention, there is a remarkable effect that the operation of positioning the adjuster bolt can be performed extremely easily.

When the baseboard is fitted to the fitting portion of the base body, the baseboard is automatically placed on the upper surface of the adjuster bolt screwed to the support, and the installation interval of the adjuster bolt is also predetermined. Once the height of the adjuster bolts is adjusted, the position of the adjuster bolts does not shift, the horizontality of the furniture placed on the baseboard is not changed, and the load of the furniture is supported by the adjuster bolts at predetermined intervals It has a remarkable effect that it can be stabilized.

[0009]

Next, an embodiment of the present invention will be described. The cabinet unit 1 as an example of furniture in the present embodiment is of an assembling type in which a bottom plate 2, a top plate 3, left and right panels 4, 4 and a rear panel 5 are separately formed of steel or the like. However, in the present invention, various types of furniture can be placed on the baseboard 12 on the base body 6.

The base body 6 is formed on the front and rear edges of a thin metal flat plate portion 6b having a rectangular shape in a plan view. The pair of fitted portions 6a, 6a are integrally bent and connected. The flat plate portion 6b of the base body 6 is fixed on the floor with an anchor screw 7. Reference numeral 8 denotes a metal support having a downward U-shaped cross section, and the support 8 has a shape capable of being fitted to the lower side of each of the fitted portions 6a from the side. The upper piece 8a of the support 8 is provided with a female screw portion (not shown) to which the adjuster bolt 9 can be screwed up and down.

On the end surface of the upper piece of each fitting portion 6a of the base body 6, a notch groove 11 having a radius slightly larger than the radius of the shaft portion 9b of the adjuster bolt 9 is formed in a semicircular shape in plan view. . Reference numerals 12 and 12 denote left and right longitudinal baseboards which can be fitted into the pair of front and rear fitted parts 6a and 6a extending in the frontage direction from above, and are formed in a downward U-shape in cross section.
2a is mounted on the head 9a of the adjuster bolt 9,
The cabinet unit 1 is placed on the upper piece 12a of the baseboard 12. When the cabinet units 1 are connected in the lateral direction (the frontage direction), the length of the baseboard 12 is formed to be the frontage length corresponding to the number of units. In addition, an operation hole 13 having a diameter smaller than the diameter of the head 9a of the adjuster bolt 9 is formed in the upper piece 12a of the baseboard 12 at every arrangement interval of each of the adjuster bolts 9 (the arrangement interval of the notch grooves 11). Then, a driver to be locked in the groove 14 on the upper surface of the head 9a can be inserted while the baseboard 12 is covered with the adjuster bolt 9. The operation hole 13 at the end in the longitudinal direction of the baseboard 12 has a semicircular shape as shown in FIG. Further, it goes without saying that a cross hole or a hexagonal hole may be formed on the upper surface of the head 9a instead of the groove 14.

Reference numeral 15 shown in FIG. 5 denotes a position of the support 8 at the end of one base body 6 or the outermost support 8 among the base bodies 6 connected in the horizontal direction so that the support 8 is not laterally displaced. The height of the fixed frame 15 is made substantially equal to the fitted portion 6a of the base body 6, and the lower piece 15a of the fixed frame 15 is fixed to the floor surface with the anchor screw 7.

Reference numeral 16 denotes a lateral skirting that covers the outside of the fixing frame 15, and a downwardly open locking piece 17 whose base end is fixed to the inner surface of the side plate 16a of the lateral skirting 16 is raised on the fixing frame 15. It is configured to be locked to the side piece 15b. A wiring cord (not shown) can be inserted into the space above the flat plate portion 6b of the base body 6, and although not shown, the fixed frame 1
5 can be pulled out of the base body 6 through a through hole formed in the side piece 15b of the side board 5 and the side plate 16a of the lateral baseboard 16. When the through hole is not used, the through hole is made of synthetic resin or the like. The cover body can be detachably closed by the cover body.

With this configuration, the base body 6 is arranged on the floor surface so that the front and rear end fitted portions 6a extend in the frontage direction, and a support with an adjuster bolt 9 is provided in each fitted portion 6a. When the body 8 is inserted from the side, the adjuster bolt 9
Abuts against the notch groove 11 in the fitted portion 6a, whereby the position of the adjuster bolt 9 is automatically determined.

When the side ends of the adjacent base members 6 are abutted against each other, the support members 8, 8 are located inside the fitted portions 6a, 6a.
Are straddled, and the left and right fitted portions 6
Since the shaft portion 9b of the adjuster bolt 9 is sandwiched between the notched grooves 11 and 11 on the side end surfaces of the a and 6a, the work of fixing the support body 8 to the floor surface or the base body 6 by screwing or the like is not performed.
The position of the adjuster bolt 9 and the support 8 can be determined, and there is no displacement. Therefore, in this state, it is only necessary to fix the base body 6 to the floor surface. The baseboard 12 is fitted on the plurality of adjuster bolts 9, and the adjuster bolts 9 are rotated from one upper side thereof to raise the height of the baseboard 12. After deciding the size, if furniture (cabinet unit 1) is placed on it,
It is possible to maintain the horizontality of the furniture left and right and front and back, and to stably support the load of the furniture.
