Description

[Detailed Description of the Invention] This invention relates to an adjuster for storage furniture, such as a wardrobe, which is placed under the base plate of the storage furniture to keep the storage furniture in a horizontal state.

BACKGROUND ART In recent years, tall wall-mounted storage furniture such as wardrobes, which are installed against a wall, have become mainstream in order to make more effective use of living space.

This type of storage furniture (in order to secure the storage capacity, it is configured to be stored in an upright position up to the upper limit of arm's reach, so the thickness of the component parts is thicker and the overall weight is lower than the conventional height. This is a significant increase compared to low storage furniture.

For this reason, this type of storage furniture lacks installation stability against external pressures such as earthquakes and heavy own weight, and especially when installed on soft floors such as tatami mats, the storage furniture tends to sag partially due to its own weight. There is a risk that it will be delayed.

In order to prevent the above-mentioned inconvenience, an adjuster is attached to the front side of the base plate of the storage furniture, and the adjuster corrects the inclination of the storage furniture so that the storage furniture is always installed horizontally.

The conventional adjuster shown in Figs. 7 and 8 consists of a side plate A of storage furniture, a bracket B fixed to the inner surface of A, a screw rod C as a height adjuster screwed into this, and It consists of a platen platen attached to the lower end of the screw rod C.

The upper part of a screw rod C having a tool operation groove is inserted into the operation hole F penetrated through the base plate E, and when a screwdriver is inserted into this operation hole F and the screw rod C is rotated, the platen is rotated. is pressed against the floor surface G, and the front side of the storage furniture is in a lifted state.

However, in the conventional adjuster described above, when the screw rod C is rotated to press the platen against the floor surface G, the upper end of the screw rod C is buried in the operation hole F. The operating groove moves up and down into the operating hole F of the base plate E of the furniture, and the screwdriver easily comes off from the operating groove, making the adjustment operation troublesome.

This invention was developed in view of the above points, and the purpose of this invention is to attach an operating tool to a bracket that is fixed to the inner surface of the side panel of furniture and that is in contact with the bottom surface of the base plate. A cap nut is provided as a cap nut, and this cap nut is screwed together with a threaded rod at the upper end of the column serving as a height adjuster having a pressure plate at the lower end, so that the column is moved up and down as the cap nut rotates. To provide an adjuster for storage furniture of this kind with good operability, in which the upper surface of a cap nut serving as an operation surface does not rise or fall regardless of the vertical movement of a support column.

Next, the adjuster for storage furniture according to this invention will be explained with reference to an embodiment shown in the drawings.

First, a first embodiment will be explained with reference to FIGS. 1 to 3.

As shown in Fig. 1, the adjuster consists of a bracket 1 having a U-shaped cross section, a column 2 as a height adjuster that is inserted through the bracket 1, and an operating tool for the column 2 that is screwed into the column 2. It is composed of a cap nut 3 and a retaining ring 4 that is inserted into the cap nut 3.

To explain in more detail, the bracket 1 includes a side plate A of furniture,
A mounting part 5 that comes into contact with the inner surface of the main plate E, an upper bending plate 6 as a horizontal part that comes into contact with the lower surface of the main plate E, and this upper bending plate 6
and side girder curved plates 7 as horizontal parts facing each other.

An insertion hole 6a is provided approximately in the center of the upper bending plate 6, and a square holding hole is provided in the lower bending plate 7, into which the support column 2 is inserted at a position facing the insertion 7L6. 7
A is provided.

Incidentally, the base plate E of the furniture is provided with an operation hole 7a penetrated at a position corresponding to the insertion hole 6a.

The above-mentioned cap nut 3 has an operating part 3a formed of an operating groove for inserting a screwdriver into the upper end surface of the body part 3b, and a retaining piece 3C made of a flange is integrally connected to the body part 3b. is formed.

The outer diameter of the body portion 3b matches the inner diameter of the insertion hole 6a, and the outer diameter of the retaining piece 3C is made sufficiently larger than the inner diameter of the insertion hole 6a.

The length of the body part 3b is such that when the body part 3b of the bag nut 3 is inserted into the operation hole F of the furniture, the operation part 3a is approximately aligned with the upper surface of the base plate E or is located slightly below. It is set.

A nut portion 3d, which is screwed into a threaded rod portion 2a of the post 2, which will be described later, is formed on the body portion 3b from the lower end surface side of the retaining piece 3C.

On the other hand, the retaining ring 4 has an inner diameter that matches the outer diameter of the body portion 3b, and the outer diameter is equal to the outer diameter of the main plate E.
It is slightly smaller than the inner diameter of the operation hole F.

Next, the support column 2 inserted into the holding hole 7a has a threaded rod portion 2a formed from the upper end surface to the center portion, a rotation prevention portion 2b formed continuously with the threaded rod portion 2a, and a rotation prevention portion 2b formed continuously from the screw rod portion 2a. A disk-shaped platen 2C is fixed to the lower end of the motion preventing portion 2b.

The rotation preventing portion 2b has a square cross section and is inserted into the holding hole 7a in alignment with the holding hole 7a.

Next, a method for assembling and installing the adjuster will be explained.

The cap nut 3 is inserted from below the insertion hole 6a of the upper bending plate 6 with the operating part 3a facing upward, and the retaining piece 3C is brought into contact with the lower surface of the upper new bending plate 6.

Next, a retaining ring 4 is attached to the body part 3b from the top of the nut 3.
is inserted and brought into contact with the upper surface of the upper bending plate 6.

Therefore, the cap nut 3 is prevented from being pulled out by the retaining ring 4 on the upper bending plate 6, and is rotatable.

Subsequently, the support column 2 is inserted into the holding hole 7a from below the lower bending plate 7 with the threaded rod portion 2a facing upward.

With the rotation prevention part 2b aligned with this holding hole 7a,
When a driver is inserted into the operation part 3a of the cap nut 3 and rotated counterclockwise when viewed from the top, the threaded rod part 2a and the nut part 3d of the cap nut 3 are screwed together.

Furthermore, the body portion 3b of the cap nut 3 is inserted into the operating hole 7 of the base plate E.
The upper bending plate 6 is inserted from below, and the upper surface of the upper bending plate 6 is brought into contact with the lower surface of the base plate E, and the mounting portion 5 is brought into contact with the inner surface of the side plate A.

The bracket 1 is fixed to the side plate A with bolts through the bolt insertion holes 5a.

With the bracket 1 attached from the side plate A to the base plate E, the upper end surface of the operating portion 3a of the cap nut 3 is positioned flush with the upper surface of the alley plate E.

The function of the adjuster assembled in this way and attached to the lower part of the storage furniture will be explained.

Place the storage furniture in a predetermined position, insert a screwdriver into the insertion part 3a of the cap nut 3 that rotates in the fixed position, and then tighten the cap nut 3.
Rotate clockwise when viewed from above.

The threaded rod portion 2a that is screwed into the nut portion 3d is likely to be moved by the cap nut 3, but since the rotation prevention portion 2b is prevented from rotating by the holding hole 7a of the bracket 1, the cross-dressing 2
It does not rotate itself.

That is, the support 2 is moved downward by the rotation of the cap nut 3 in the fixed position, and the platen 2 is integrated with the support 2 as shown in FIG.
C is pressed against the floor surface G without rotating, and the front side of the storage furniture is lifted from the floor surface G.

On the other hand, contrary to the above, when the cap nut 3 is rotated counterclockwise, the threaded rod part 2a is gradually screwed into the nut part 3d, so the support column 2 rises without rotating, and the discontinued 2C leaves the floor and returns to the state shown in Figure 2.

If the length of the nut portion 3d is increased by extending the retaining piece 3C of the improved arrangement nut 3 in the axial direction, the adjustment range of the height of the support column 2 can be further expanded.

The description of the first embodiment is above, but further details of the second to fourth embodiments are explained above.
An example of this will be explained with reference to FIGS. 4 to 6.

However, the same parts as in the first embodiment are denoted by the same reference numerals.

As shown in FIG. 4, the second embodiment uses a spring 8 instead of the removal stop ring 4 of the first embodiment.
This spring 8 is inserted through the pillar 12 and the lower new music board 7
and the lower end surface of the cap nut 13.

This spring 8 causes the cap nut 13 to be pressed against the lower surface of the upper bending plate 6, so that the retaining ring 4
The operation part 13a is always located near the top surface of the main plate E.

Further, a substantially dish-shaped scrap 9 is attached to the lower end of the support 12, and the scrap 9 is rotatable relative to the support 12, but the support 12 itself cannot be rotated into the holding hole 7a of the bracket 1. Since it is blocked, when the cap nut 13 is rotated, the column 12 is lowered and the scrapped product 9 is pressed against the floor surface G without being rotated.

In the third embodiment, as shown in FIG. 5, a cut is made in the upper bending plate 16 of the bracket 11 from the center of this side edge to the mounting part 15 side to a position corresponding to the holding hole 17a. An insertion hole 16a having an insertion width X is formed.

On the other hand, the cap nut 23 inserted into the insertion hole 16a is formed with a body part 23b having a large diameter larger than at least the insertion width X, and a flange 23C. An engagement groove 23e is formed between the flange 23C and the flange 23C.

The outer diameter Y of the bottom peripheral surface of this engagement groove 23e is equal to the insertion width X
The cap nut 23 is slightly smaller than the insertion hole 1.
6a from the side, and the nut portion 23d of this cap nut 23 and the threaded rod portion 2a of the support column 2 are screwed together.

The width of the engagement groove 23e matches the thickness of the flange 16.

Furthermore, in the fourth embodiment, as shown in FIG.
From the side edge of 7, an insertion hole 2 equivalent to the above insertion hole 16a is inserted.
A holding hole 27a is formed opposite to the holding hole 27a.

Therefore, it is possible to insert the screwed cap nut 23, the engagement groove 23e of the support column 2, and the rotation prevention portion 2b into the insertion hole 26a and the holding hole 27a, respectively, from the side of the bracket 21. can.

When this embodiment is attached to storage furniture, the direction in which the cap nut 23 and support column 2 are inserted into the insertion hole 26a and the holding hole 27a corresponds to the full width direction of the storage furniture.

Therefore, the position of the operation hole F provided in the base plate E for operating the cap nut 23 can be freely set along the entire width direction within the range where the cap nut 23 and the support column 2 do not fall off from the bracket 21.

In both the first to fourth embodiments described above, the operation parts 3a, 1
Of course, 3a and 23a may be hexagonal holes into which a hexagonal wrench is inserted and can be rotated.

Furthermore, the cross-sectional shape of the rotation prevention parts 2b, 12b of the columns 2, 12 and the shape of the inner corner edges of the holding holes 7a, 17a and the holding hole 27a, which match this shape, may be made into a polygonal shape other than a square shape. Similarly, rotation of the columns 2, 12 is prevented.

As explained above, according to the adjuster according to this invention, the retaining piece on the outer periphery of the cap nut-shaped operating tool is brought into contact with the lower surface of the horizontal part of the bracket that is fixed to the bottom of furniture, etc. to support it. The upper end screw part of the pillar with a discontinued part at the lower end is screwed into the bore nut part of the operation tool, and the horizontal part of the bracket is loosely connected to the pillar, so that the weight of furniture, etc. is transferred through the bracket. This is transmitted to the retaining piece of the cap nut-shaped operating tool, and is supported by the scrap at the lower end of the rear column.

Therefore, when raising and lowering the discontinued part at the lower end of the column to perform an adjustment operation using the adjuster, the top surface of the cap nut-shaped operating tool is rotated with a screwdriver, and the threaded stem at the upper end of the column is screwed into the inner cavity of the operating tool. It is only necessary to adjust the insertion length, and during the adjustment operation, the operating part on the top surface of the cap nut-shaped operating tool that is engaged with the driver does not move up and down with respect to parts such as brackets and furniture, and the adjustment work is difficult. This has the effect of making it easier.

Further, according to the adjuster according to the invention, the weight of the furniture, etc. supported by the adjuster is received by the outer circumferential retaining piece of the cap nut-shaped operating tool through the bracket, and is transferred through the nut portion of the operating tool's mouth. Since the weight is transmitted from the upper threaded portion of the column to the discontinued portion at the lower end of the column and supported, the weight is not unevenly transferred to the threaded portion, and there is no risk of damage to the adjustment screw.

Therefore, it can be used not only for lightweight furniture but also as a support adjuster for heavy parts such as the base plate of buildings.
