Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning device for furniture, etc., and an object of the present invention is to prevent mistakes in the mounting direction of a positioning section.

Some kitchen furniture, such as sinks, have a separate structure from the furniture base frame to facilitate installation.

In this case, a positioning member is usually provided on the underside of the furniture body, and it is common to position the furniture body with respect to the base frame by supporting this with the inner surface or hole of the base frame. It is. The positioning member was provided with a guide portion such as an inclined portion to facilitate joining to the inner surface or hole of the base frame.

In other words, the positioning member has a direction of attachment to the furniture body due to the presence of the guide portion. In the past, the guide part lost its function in the positioning part because it was installed in the opposite direction, and it took time and effort to position it with the base frame. The present invention eliminates the drawbacks of such a conventional structure, and embodiments thereof will be described below with reference to the accompanying drawings. The figure shows base frame 1,
This shows a combination type kitchen furniture consisting of a plurality of furniture main bodies 2 and a common top plate 3.

That is, first install only the base frame 1 on the floor, adjust the levelness etc., then set the furniture bodies 2 on the base frame 1 according to your preference, and finally place the furniture bodies 2 above them. The common top plate 3 is covered. A positioning member 4 with respect to the base frame 1 is provided on the bottom surface of the furniture main body 2.

The positioning member 4 is to be joined to the inner surface of the base frame 1, and an inclined guide portion 5 is formed on the outer surface of its tip, that is, a portion facing the inner surface of the base frame 1, and the above-mentioned positioning member 4 is joined This can be done quickly and reliably.

In order to eliminate the longitudinal directionality of the positioning member 4, it is conceivable to provide the guide portion 5 on the opposite side as shown by the dotted line in FIG.
Further, the positioning member 4 is attached to the bottom plate 2a of the furniture main body 2 via screws 6, as shown in FIG.

Reference numeral 7 denotes an insertion hole formed in the positioning member 4 for passing the threaded main body portion 6a of the piece 6, and one end thereof is open at the bottom of a recess 8 formed in the distal end surface of the same layer determining member 4.

The concave portion 8} is where the raised head 6b of the screw 6 faces. Now, the inner diameter of the recess 8 is a, the depth is b, the inner diameter of the camellia through hole 7 is c, the length is d, the outer diameter of the rocking part 6b of the screw 6 is e, and the length of the main body part 6a is f. When, of course, c<e
The relationship is set as mia, and the relationship is set as b+d>f>d.

Therefore, in a normal state, the main body part 6a of the screw 6 protrudes from the positioning member 4 by an amount f-d and can be screwed into the bottom plate 2a, thereby allowing the same-level layer determining part 4 to be attached. Yes (see Figure 3).

Next, if an attempt is made to attach the positioning member 4 upside down as shown in FIG. 4, the screw main body portion 6a will not reach the bottom plate 2a due to the relationship b0d>f, so attachment will not be possible.

In the above embodiment, b+d>f, but the screw main body 6
Even if the tip of a reaches the bottom plate 2a, if the amount of screwing into the bottom plate 2a is small, the screw 6 will not exert its mounting force. That is, the length f of the screw main body portion 6a may be set to the following relationship: b+d>f>d or b+df>d.

As described above, according to the present invention, by adjusting the dimensions of the positioning member in relation to the screws, it is possible to reliably prevent the positioning member from being installed in the wrong direction, thereby fully demonstrating the function of the positioning member. It is possible to do so.

Note that the spirit of the present invention can of course be applied to equipment other than furniture.

Claims (1)

[Scope of Claims] 1. A positioning member having a guide portion at its tip is attached to a structure such as furniture with a screw, and an insertion hole for the screw is formed in the positioning member, and a hole is provided from the tip surface of the positioning member. The bottom of the recess is also open at one end, and the inner diameter of the recess is a, the depth is b, the inner diameter of the insertion hole is c, the length is d, the outer diameter of the head of the screw is e, and the body of the screw is A positioning device for furniture, etc., characterized in that, where f is the length, c<e≦ab+d>f>d or b+d≒f>d.
