Description

[Detailed explanation of the invention] [Industrial application field] This invention can be applied to soft wall boards and ceiling boards such as gypsum board, thin plywood board, ALC board, etc.
This invention relates to an article fixing device for soft boards used to attach interior items such as shelf brackets, curtain rail brackets, and lighting fixtures.

[Conventional technology]

Conventionally, when attaching desired equipment such as coolers, shelves, hooks, lighting equipment, partition plates, etc. to plasterboard or the like, it has been common to adopt the following two methods. The first is as shown in Fig. 8, when a wooden base plate b is installed on the back side of a plasterboard etc. a in advance, and for example when attaching a hook c,
This is a method of fixing by screwing into a wood screw d.
As shown in FIG. 9, this is a method in which an anchor member e or f that expands on the back side of a plasterboard or the like is used without using a base plate.

In addition, in the case of hard walls etc.,
In the publication, when fixing a plate to be fixed to concrete, etc., fixing nails are passed through a through-hole provided in the main body and through a plurality of intersecting through-holes provided at a distance from each other in the plate to be fixed. The method for fixing the plate to be fixed is described.

[The problem that the idea aims to solve]

Among the conventional techniques mentioned above, when using the former method, even though it cannot be applied to a place without a base, people often forget to apply the base in advance, and moreover, the cost for constructing the base is high. It has the disadvantage that it takes a long time. In addition, when using the latter method, relatively large holes (actually 8 to 8
10mm) and cannot be removed once installed. It takes up a lot of space on the back. It easily collapses from the hole and wobbles. A tool for drilling is required. Problems such as these remain.

Furthermore, the method described in JP-A No. 48-7148 is based on the method described in JP-A No. 48-7148, since the wall is a hard object, so if the fixing nails are hammered close together, the concrete etc. will crack and cannot be fixed. The plate must have multiple through holes spaced apart from each other, fixing nails must be passed through each through hole, and these fixing nails must be nailed into concrete with sufficient distance to fix the plate. In order to cover the through hole, the size of the main body would have to be large, far exceeding the size of the head of a nail, which was an unsightly method.

With this idea, since the board to be attached is a soft board, even if fixing nails are driven into the soft board in close proximity to each other, the soft board will not crack. The plurality of through holes provided are combined into a single mounting hole, and the fixing nails are converged in a cross shape into such a hole or a conventional mounting hole made in the article to be fixed. The object to be fixed can be fixed by passing it through the plate and hitting it against a soft board, and thereby the size of the main body for covering the through-hole or through-hole of the object to be fixed can be reduced to the size of the head of a nail. The aim is to make it possible to do so.

[Means to solve the problem]

That is, this invention provides a fixing device consisting of a main body, a fixing piece, and an article to be fixed. , two diagonal through holes are provided from the beveled surface toward the bottom surface of the main body, and in this case, these through holes are substantially symmetrical with respect to the central axis of the main body and approach each other as they go toward the bottom surface of the main body. At the same time, the fixing pieces intersect near the center axis of the main body near the bottom surface, and the fixing pieces are passed through the diagonal through holes provided in the main body, and the two penetrating fixing pieces are opened in the article to be fixed. The present invention proposes an article fixing device for a soft plate that is configured to penetrate through one through hole, thereby solving the conventional problems.

[Effect]

The fixture having the above configuration can firmly fix the article to be fixed without causing the soft plate to break even when the fixture is struck against the soft plate.

〔Example〕

Next, this invention will be explained using a case where the soft board is a gypsum board as an example.

In FIGS. 1a, b, and c and FIG. 2, 1 is a main body made of a relatively hard material such as hard synthetic resin or metal, and the outer periphery of the top surface 2 of this main body 1 is approximately in the shape of a truncated cone. The inclined surface 3 has a substantially symmetrical shape with respect to the center of the main body 1, and a bottom surface 4 of the main body 1.
The openings 5a and 6a of the two diagonal through holes 5 and 6 are formed so that they approach each other as they go toward the bottom surface, and in the case of the one shown in FIG. 7, goods 10
It is adapted to abut against the inner wall of the mounting through hole 10'.

When using the article fixing tool 8 having the above configuration, the article 10 to be fixed, such as a hook, is pressed against the plasterboard 9, and the through hole 1 for attaching the article 10 is pressed against the plasterboard 9.
Apply the article fixing device 8 of this invention to the part 0',
As shown in FIG.
In this way, the fixing pieces 11,
11 are driven into the gypsum board 9 so as to cross each other. Note that the bottom surface 4 of the article fixing device 8 in FIG. 2 is flat.

FIGS. 3a, b, and c show the seventh piece as the fixed piece 11.
This is an example in which a fixing piece 11a such as a nail having a flat cross-sectional shape as shown in Figures a and b is used. In place of the tapered reduced inclined surface 7, a reduced step portion 12 is formed by cutting out the peripheral edge of the bottom surface 4 and inserting it into the attachment hole 10' of the article 10. Although it has been
In the above example and each example described below, it is an optional matter whether or not to provide the tapered reducing inclined surface 7 or the reducing step part 12 on the bottom surface 4 of the main body 1, and when provided, it is necessary to set the tapered reducing slope 7 or the reducing step 12 at the exact position described above. This has the effect of increasing the pressing force against the article 9 to be fixed.

FIGS. 4a, b, and c show an example in which a pair of beveled surfaces 13, 14 are formed on the outer periphery of the top surface of the main body 1, and are symmetrical with respect to the center thereof. It is opened at 14.

5a, b, and c differ in that the main body 1 of each of the above-mentioned examples had a circular contour, but is approximately rectangular, and in this case, the outer periphery of the top surface 2 is Forming the beveled surfaces 19, 20 as in the example of
Diagonally cut through holes 5 and 6 are opened in these diagonally cut surfaces 19 and 20.

In the examples shown in FIGS. 3 to 5 above, the method of use is the same as that shown in FIG. 2. In addition, for practical purposes, it is also considered to provide internal threads in the diagonal through holes 5 and 6 and use wood screws as fixing pieces.

[Effect of idea]

According to the article fixing device for soft plates of this invention, the following practical effects can be obtained. In other words, soft wall panels such as plasterboard, frames on ceiling panels, etc.
Hooks, shelf brackets, lighting fixtures, etc. can be fixed or attached easily and quickly by simply driving in two fixing tools.

No special fittings or tools are required for installation.

When replacing or removing it, it can be easily removed, and the hole after removal is small, so you can make it less noticeable by simply rubbing it with your fingers.

The size of the main body of the fixture can be reduced to approximately the size of the head of a nail, and the appearance can be made unnoticeable.
