Description

[Detailed explanation of the invention] [Industrial application field] This invention is used to attach shelf brackets, etc. to relatively soft walls such as gypsum board, thin plywood board, ALC board (hereinafter referred to as gypsum board, etc.), The present invention relates to an article fixing device that allows hooks and the like to be easily and reliably attached to a ceiling surface made of a manufactured board or the like.

[Conventional technology]

Conventionally, when attaching desired equipment such as coolers, shelves, hooks, lighting equipment, partition plates, etc. to gypsum board, it has been common to adopt the following two methods. The first is as shown in Fig. 9, 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,
The second method is a method of fixing by passing a wooden screw d through a plasterboard or the like and screwing it into the base plate b.
As shown in the figure, this is a method that does not use a base plate and uses anchor members e or f that expand on the back side of a plasterboard or the like a.

[The problem that the idea attempts to solve]

Among the conventional techniques mentioned above, in the case of the former method, it is not possible to apply it to a place without a base, and people often forget to apply the base in advance, and moreover, the cost of constructing the base is high. The disadvantage is that it takes a lot of 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. Requires tools for drilling holes. There are still some issues that remain.

[Means to solve the problem]

Here, this invention provides a stepped part or a tapered part 3 at the lower part of the fixture body 1 to form a bottom surface 2 that is one size smaller than the fixture body 1, and the bottom surface 2 is
Insertion pieces 12 and 17 for temporary fixing are provided protruding from the surface, and two or more nail guide holes 6 are provided from the surface 5 of the head 4 of the fixing device body 1 so that the guide holes 6 are approximately aligned with the center of the fixing device body 1. The caps are diagonally perforated so as to maintain positional balance and converge close to each other near the bottom surface 2, and the head 4 can be crowned with a cap 8 made of soft synthetic resin. The present invention proposes an article fixing device for gypsum board, etc., which is constructed as follows.

〔Example〕

Next, the case where this invention is used for gypsum board will be explained in detail with reference to the drawings.

First, in FIGS. 1 and 2, reference numeral 1 denotes a fixture body made of a cylindrical body made of hard synthetic resin, and at its lower part there is a bottom surface 2 that is one size smaller than the main body 1 and a stepped portion 3 around it. On the other hand, they are provided obliquely through the fixing device so as to maintain substantially positional balance with respect to the center of the fixing device main body 1, and to converge close to each other near the bottom surface 2 of the main body 1. A through hole 7 for driving a temporary fixing pin (described later) is formed so as to penetrate from the surface 5 of the head 4 of the head 1 to the bottom surface 2. This through hole 7 does not necessarily need to be provided through the center of the main body 1 as shown in the figure, but it is necessary to at least prevent it from interfering with the guide hole 6. Furthermore, the surface 5 of the head 4 is not limited to a conical shape as shown. Note that instead of the stepped portion 3, a tapered portion may be formed toward the bottom surface 2, and these portions are inserted into a through hole of the object to be fixed, which will be described later, and have the effect of pressing the surface of the object to be fixed. Furthermore, the fixture body 1 can also be made of metal.

What is shown in FIG. 3 is a cap 8 to be attached to the fixture main body 1, and this cap 8 is made of soft synthetic resin and is configured to fit tightly into the fixture main body 1.

The manner in which the article fixing device having the above-described structure is attached will be explained with reference to FIG. The stepped or tapered portion 3 of the fixture main body 1 is inserted into the hole 11.
After inserting the pin 12 as an insertion piece into the plasterboard 9 with your finger through the temporary fixing through hole 7 and determining the positional relationship between the bracket 10 and the fixture main body 1 with respect to the plasterboard 9, Nails are driven into the plasterboard 9 through the guide holes 6, and these guide holes 6 maintain approximately positional balance at the center of the body 1 as described above, and are close to each other near the bottom surface 2 of the body 1. The brackets 10 are firmly attached to the gypsum board 9 because they penetrate diagonally so as to converge close to each other, and since the tips of these nails 13 are driven outward toward each other, they are prevented from coming off as a whole. Ru. Next, the cap 8 is attached to the main body 1 to complete the work.

What is shown in FIG. 5 is the main body 1 and the cap 8.
In this example, a male thread 14 is provided on the outer periphery of the main body 1, and on the other hand,
By cutting a female thread 15 into the cap 8, the two can be screwed together after the nail 13 is driven.

FIG. 6 shows another example of fitting the main body 1 and the cap 8. In this case, a suitable tapered surface 16 is formed on the outer periphery of the main body 1, and the cap 8 is pushed into the tapered surface 16 and fitted. It is.

FIG. 7 shows an insertion piece 17 for temporary fixing such as a rivet or pin inserted from the bottom surface 2 of main body 1 instead of protruding through hole 7 into main body 1 for inserting the temporary fixing pin 12 described above.
The work is started by driving the insertion piece 17 through the article to be fixed and into the plasterboard. In this case, the protruding position of the insertion piece 17 does not necessarily have to be at the center of the main body 1.

In the embodiment shown in FIG. 7, the insertion piece 17 such as a separate stud or pin is integrated with the main body 1, but as shown in FIG. 8, the insertion piece 18 is integrated with the main body. It is also possible.

In addition to the above, the following aspects are also possible.

The nail 13 may be a screw nail.

A type in which a female thread is formed in the guide hole 6 and a screw is screwed into the female thread is considered.

In the example described above, three guide holes 6 are formed, and accordingly, three nails are driven into the guide holes, but depending on the case, two or four or more nails may be used.

[Effect of idea]

According to this invention, a slightly smaller stepped portion or tapered portion 3 formed at the bottom of the fixture main body 1 is fitted into the mounting hole 11 of the bracket 10 to fix the temporary fixing insertion piece 12 or 17 to the bracket, etc. After inserting the fixing nail into a relatively soft wall surface such as a gypsum board through the member, the fixing nail can be driven through the guide hole of the fixing device main body 1. Driving nails can be done easily, and since the nail can be driven after confirming the installation position, there is no need to redo the work. Therefore, it is possible to avoid making unnecessary holes in the wall surface by re-driving the nails, and since the fixing nails are driven diagonally and convergently, it is effective in maintaining the installation strength. Furthermore, since the cap can be mounted on the head of the fixing device main body, there is no risk that fingers or objects will be damaged by the head of the fixing device such as a nail during use.
