Abstract

PROBLEM TO BE SOLVED: To facilitate installation of a hanger having a mounting base board provided with a hook part and fixed in a mounted face by means of a nail driven through a nail insertion hole by arranging a temporality locking sheet holding the mounting base board in a mounting position in an unnailed condition on the mounting base board back face. SOLUTION: In installation of a hanger to a wall W and the like, a mounting base board 3 is temporarily fixed to the wall W mounting position via a temporarily locking sheet 5 on the back face. In this way, both hands of a worker can be used freely, so that the worker uses both hands for inserting nails 6 through respective nail insertion holes 34b in projection parts 33a, 33b, respectively, and driving them inward by means of a hammer and the like. Subsequently, a connection shaft 41 in a cap 4 is fitted in an opening part 35 of the mounting base board 3. In this process, the nail 6 is driven into the wall W through the temporarily locking sheet 5, so that the temporarily locking sheet 5 is stuck around the nail 6. Therefore, a part of intensive force is dispersed to the locking sheet 5 even when an excessive load or shock is applied to a locking hook 21 in a hook part, and a nail hole in the wall W can be prevented from expanding.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger used for hanging an object on a wall or the like, and more particularly, to a hanger fixed to a relatively fragile wall such as mortar or gypsum board with a nail or the like. The present invention relates to a hanging device.

[0002]

2. Description of the Related Art This type of hanging tool has a general configuration,
A mounting board made of metal, wood, or synthetic resin to be mounted on a mounting surface such as a wall, and a hook portion (hook portion) provided on the mounting substrate. When classified, 2 types of adhesive type and nailing type
It is roughly divided into two.

[0003] The former adhesive type suspender has an adhesive means such as a double-sided adhesive tape on the back surface of the mounting substrate (the surface opposite to the surface to be mounted), and attaches to the surface to be mounted via the adhesive means. Fixed. On the other hand, in the latter nailing type hanging tool (pin hook), a nail insertion hole is formed in the mounting board, and the nail is fixed to the mounting surface with a nail driven through the nail insertion hole. You.

[0004]

The adhesive-type hanging tool simply peels off the release paper adhered to the double-sided adhesive tape.
In particular, it is convenient in that it can be easily mounted on the mounting surface without using a tool such as a hammer and without damaging the mounting surface.

However, since the adhesive tape is used, its holding force is weak, and it cannot withstand a large hanging load. Further, there is an inconvenience that even if it can be attached to a smooth surface such as a tile or a wood grain panel, it cannot be applied to a non-smooth surface such as a cloth wall, a concrete surface, and a mortar surface.

On the other hand, according to the nailing type hanging tool,
Since the mounting board is firmly fixed to the mounting surface by the nail, a large load can be suspended. However, there is a difficulty in the mounting work.

That is, a so-called carpenter's work is performed using a nail and a hammer for driving the nail. At this time, the mounting board is pressed down with one hand and positioned.
After the nail is inserted into the nail insertion hole with the other hand, hammering must be performed, and the mounting is troublesome. In addition, when the mounting board is small, the hand may be accidentally hit.

Further, when the surface to be mounted is relatively brittle, such as mortar, thin plywood or gypsum board, play may occur in the nail if the end face of the nail hole is chipped once due to excessive load or impact. Each time this was repeated, the nail hole widened and the nail sometimes came off.

[0009] The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a nail-type hanging tool.
It is an object of the present invention to provide a suspension tool that can be temporarily fixed to a mounting surface before nailing and that prevents a nail hole from being widened by an excessive load or impact.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a mounting board having a nail insertion hole and a hook provided at a predetermined portion of the mounting board. In a hanging tool fixed to a mounting surface such as a wall with a nail driven through a nail insertion hole, a back surface of the mounting board has a predetermined adhesive force to the mounting surface, It is characterized in that a temporary fixing sheet for holding the mounting substrate at the mounting position on the mounting surface in a state before hitting is provided.

As described above, since the temporary fixing sheet is provided on the back surface of the mounting board, the hanging tool can be accurately positioned at the mounting position, and the nail can be held without holding the hanging tool with one hand. Can be easily driven. Further, the presence of the temporary fixing sheet prevents the nail hole from expanding.

As the temporary fixing sheet, a double-sided pressure-sensitive adhesive sheet is preferably employed because of its low cost and availability. In this case, it is preferable that the adhesive strength of the double-sided pressure-sensitive adhesive sheet to the mounting surface is weaker than the pressure of the double-sided pressure-sensitive adhesive sheet to the mounting substrate.

According to this, when the mounting substrate is removed from the mounting surface, the double-sided PSA sheet can be peeled off from the mounting surface together with the mounting substrate. That is, the double-sided pressure-sensitive adhesive sheet is not left on the mounting surface side.

Further, as the temporary fixing sheet, a foam sheet having a large number of independent micro suction cups on a surface opposite to the mounting surface can be applied.

According to this foam sheet, the mounting substrate can be temporarily fixed to the surface to be mounted by the sucker action simply by pressing against the surface to be mounted without using an adhesive. Therefore, for example, to change the mounting position,
Even if the foam sheet is removed from the mounting surface together with the mounting substrate, the problem of adhesive residue does not occur at all.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to an embodiment shown in the drawings.

As shown in the perspective view of FIG. 1 and the front view of FIG. 2, the suspension 1 includes a mounting board 3 and a hook 2 mounted on the mounting board 3. In this embodiment, the hook portion 2 includes a hook 21 and a ring portion 22 formed by bending or bending a single wire, and the ring portion 22 is provided.
And is rotatably mounted on the mounting substrate 3 via.

According to this embodiment, the mounting substrate 3 is made of a disc made of synthetic resin, and the mounting substrate 3 is removably covered with the bowl-shaped cap 4 shown in FIG. Referring also to FIG. 4, an engaging groove 3 for rotatably receiving the ring portion 22 of the hook portion 2 is provided on a peripheral portion of the mounting substrate 3.
8 are formed over the entire circumference.

In the peripheral portion of the mounting substrate 3, an engaging groove 3 is provided.
Locking piece 3 for preventing ring portion 22 from falling off
6, 37 are partially formed. In this embodiment, since the ring portion 22 is welded at the butt end of the wire, in order to fit the hook portion 2 into the engagement groove 38, the ring portion 22 is hooked on the locking piece 36, 2
The joint between the hook 2 and the hook 21 is rotated to the position of the tip of the locking piece 37 to be fitted.

On the front surface 31 of the mounting board 3, a projection for nailing is provided. The nailing projections are for increasing the wall thickness, and according to this embodiment, the three projections 33a to 33a-3
3c is arranged at each vertex position of the inverted isosceles triangle in the front view of FIG. That is, 2
The three projections 33a and 33b are arranged so as to form a pair on the left and right, and one projection 33c is arranged below the front surface 31.

In this case, the upper two projections 33a,
Nail insertion holes 34a and 34b are formed in the 33b so that the nailing direction with respect to the mounting surface W such as a wall is obliquely downward. On the other hand, the mounting surface 33c is formed in the lower projection 33c. A nail insertion hole 34c is formed so that the nailing direction for W is obliquely upward. In addition, each convex part 33a-3
3c is inclined such that the head of the nail 6 that is driven obliquely is closely attached without any gap.

At the center of the front surface 31 of the mounting board 3, an opening 35 is formed in which a connecting shaft 41 provided on the cap 4 is forcibly fitted. With 35, the cap 4 is coaxially put on the mounting substrate 3 and connected thereto.

As described above, the hanging device 1 is a nail-type pin hook, but as shown in FIG. 4, the back surface (the surface facing the mounting surface W) 32 of the mounting substrate 3 is provided. A temporary fixing sheet 5 is attached to the mounting surface W.

FIG. 5A is an enlarged view showing an example in which a double-sided adhesive tape 5a is used for the temporary fixing sheet 5. According to this, the double-sided pressure-sensitive adhesive tape 5a has a film-like tough base material 51, and pressure-sensitive adhesive layers 52 and 53 are formed on both surfaces thereof.
The pressure-sensitive adhesive layer 52 on the side facing the
The pressure-sensitive adhesive layer 53 on the side facing is weakly adhered.

In this embodiment, a test value in accordance with JISC 2107 of a value of 600 gf / 20 mm or more is used as a guide for distinguishing between strong adhesion and weak adhesion. Is weakly adherent.

As described above, the pressure-sensitive adhesive layer 53 on the mounting surface W side
Is weaker than the pressure-sensitive adhesive layer 52 on the mounting substrate 3 side, for example, even if the mounting position is changed during temporary fixing,
Since the double-sided adhesive tape 5a is adhered and held on the mounting substrate 3 side, and is not left on the mounting surface W side, the mounting position can be changed any number of times as long as the adhesive force of the adhesive layer 53 on the mounting surface W side is effective. Can be changed.

Next, FIG. 5B is an enlarged view of another example of the temporary fixing sheet 5 when the temporary fixing sheet 5b made of the foam sheet 54 having a micro sucker is used. This will be described.

In this example, the foam sheet 54 is provided on the surface of the base material 51 on the side of the mounting surface W instead of the pressure-sensitive adhesive layer 53 of the double-sided pressure-sensitive adhesive tape 5a in FIG. However, the base material 51 may be omitted, and the foam sheet 54 may be attached to the back surface 32 of the mounting substrate 3 via the highly adhesive pressure-sensitive adhesive layer 52.

As the foam sheet 54, for example, a sheet obtained by irradiating an electron beam to polyethylene containing a chemical foaming agent to form a highly foamed sheet by heating and then slicing the sheet into a predetermined thickness to form a thin sheet Then, by stretching with a heating roll to form a surface film, a sheet having a large number of independent micro suction cups on the surface can be obtained. In this example, the same type as the adsorption carpet 40 (thickness 0.3 mm) manufactured by the applicant company is used.

The individual dimensions of the micro suction cup are, for example, as fine as about 10 to 200 μm for the major axis and about 8 to 170 μm for the minor axis. Not only exerts an attraction force capable of temporarily fixing the adhesive to the mounting surface W, but also mechanical adsorption, so that there is no problem of adhesive residue as in the case of using an adhesive.

According to the suspension 1 constructed as described above,
First, the mounting substrate 3 is attached to the mounting surface W via a temporary fixing sheet 5 (a double-sided adhesive tape 5a or a temporary fixing sheet 5b formed of a foam sheet 54 having a micro suction cup) on the rear surface thereof.
Temporarily fix to the mounting position.

As a result, since both hands are free, both convex portions 33a to 33a are used as shown in FIG.
The nail 6 can be inserted into each of the nail insertion holes 34a to 34c of the 3c and driven by a hammer or the like. After a while
When the connecting shaft 41 of the cap 4 is forcibly fitted into the opening 35 of the mounting board 3, all the mounting operations are completed.

Since the nail 6 breaks through the temporary fixing sheet 5 and is driven into the mounting surface W, the temporary fixing sheet 5 is in close contact with the nail 6. For this reason, even if an excessive load or impact is applied to the locking hook 21 of the hook portion 2 later, a part of the extreme force is dispersed to the temporary fixing sheet 5, and the nail of the mounting surface W is Enlargement of the hole can be suppressed. Therefore, it is particularly useful when the mounting surface W is made of a relatively soft and brittle material such as mortar, thin veneer, or gypsum board.

In the above embodiment, the nail 6 driven by a hammer has been described as an example of the main fixing tool. However, the present invention is not limited to the nail, and any pin-shaped one can be selected. For example, a commercially available push pin or thumbtack can be used.

[0035]

As described above, according to the present invention,
By installing a temporary fixing sheet such as a double-sided adhesive tape on the back of the mounting board of the nailing type hanging tool (pin hook), it is possible to drive a nail while the hanging tool is temporarily fixed to the surface to be mounted. Since it is possible, it is free from the trouble such as pressing the mounting board by hand, and the hanging tool can be installed very easily.

Further, the temporary fixing sheet provided on the back surface of the mounting board can prevent the nail hole from expanding due to an excessive load or impact. It becomes possible to keep the trace of the nail hole of the removed trace extremely small.
