Description

[0001]
[Industrial application fields]
The present invention relates to a magnet adhering auxiliary iron plate for adhering to a surface of a nonmagnetic material so that the magnet is adsorbed to the surface of the nonmagnetic material.
[0002]
[Prior art]
FIG. 3 shows the holding tool 10 having the magnet 11 fixed to the back side. In general, in the field of stationery and household goods, many of them have magnets 11 as attachment means. If the counterpart to be attached is a surface of a magnetic material such as steel, the holding tool 10 can be attached to an arbitrary position by the attractive force of the magnet 11. However, since the non-magnetic surface is not attracted, in this case, the auxiliary iron plate 12 for magnet adsorption is attached to the surface, and the magnet 11 is adsorbed to the auxiliary iron plate surface 12 so that the holding tool 10 can be attached. Yes. It is desired that the auxiliary iron plate 12 can be peeled off, and the peeled off iron plate 12 can be used again by being attached to a new mounting position. Therefore, a conventionally known double-sided pressure-sensitive adhesive sheet 13 using a urethane elastomer as a pressure-sensitive adhesive that exhibits adhesive strength can be used again on one side of the double-sided pressure-sensitive adhesive sheet 13 when water is taken after washing. It is conceivable to attach the auxiliary iron plate 12 that is slightly smaller than the size of the double-sided pressure-sensitive adhesive sheet 13.
[0003]
In order to peel it off, one end of the double-sided pressure-sensitive adhesive sheet 13 that protrudes outside the auxiliary iron plate 12 is turned and peeled off from it, but the auxiliary iron plate 12 is thin and easily removed. If deformable, the auxiliary iron plate 12 can be easily peeled off together with the double-sided pressure-sensitive adhesive sheet 13, but in this case, in addition to the magnet's attracting force not becoming strong, the auxiliary iron plate is warped, The problem arises that it is difficult to return to a flat state. On the other hand, if the auxiliary iron plate 12 is thick and does not allow deformation, there is a problem that an extremely strong force is required to peel it off.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to solve the above-mentioned drawbacks and to easily peel off even an auxiliary iron plate having an appropriate thickness that does not weaken the attractive force of a magnet so that it can be used repeatedly.
[0005]
[Means for Solving the Problems]
To achieve the above object, the present invention is an auxiliary steel plate that is adhered to the surface of the non-magnetic body for attracting the magnet to the surface of non-magnetic material, thickness of 0. An auxiliary iron plate group composed of a plurality of auxiliary iron plate pieces having a width of 5 to 1 mm and a width of 5 to 15 mm, and the same or slightly smaller shape as the auxiliary iron plate group, and the auxiliary iron plate pieces are substantially parallel to each other on one side. And the 1st double-sided adhesive sheet which affixed and bonded end surfaces, the synthetic resin sheet which was larger than the said 1st double-sided adhesive sheet, and affixed the said 1st double-sided adhesive sheet on the single side | surface, and the said synthesis | combination It consists of a second double-sided pressure-sensitive adhesive sheet that can be used repeatedly with the urethane elastomer having the same shape as the resin sheet and the above-mentioned synthetic resin sheet affixed on one side, and from one end side of the second double-sided pressure-sensitive adhesive sheet The auxiliary iron plate pieces can be peeled off sequentially in the direction of arrangement.
[0006]
[Action]
When one end of the second double-sided pressure-sensitive adhesive sheet affixed to the surface of the non-magnetic material is turned and peeled off in the direction in which the auxiliary iron plate pieces are arranged, the thickness of the auxiliary iron plate piece is 0 . Since it is 5 to 1 mm and the width of one auxiliary iron plate piece is 5 to 15 mm which can be sufficiently peeled off by the user's force, it can be peeled off sequentially for each auxiliary iron plate piece. Since a plurality of auxiliary iron plate pieces are attached to the first double-sided adhesive sheet, they are integrated after the second double-sided adhesive sheet is peeled off. The surface of the iron plate group is formed. The first and second double-sided PSA sheets do not expose the PSA side.
[0007]
【Example】
FIG. 1 is an exploded perspective view showing an embodiment of a sticking auxiliary iron plate for magnet adsorption according to the present invention, wherein 1 is an auxiliary iron plate group consisting of auxiliary iron plate pieces 1a, 1b, 1c and 1d and 2 is a first double-sided adhesive tape 3 is a synthetic resin sheet such as a polyester film, and 4 is a second double-sided pressure-sensitive adhesive sheet that can be repeatedly used with a urethane elastomer as a pressure-sensitive adhesive.
[0008]
In the present invention, the thickness of the auxiliary iron plate pieces 1a to 1d is 0 . 5 to 1 mm. The reason is that if the thickness is 0.5 mm or less, the attractive force of the magnet is not strong, and the waist is weak and cannot bend easily, and if it is 1 mm or more, it is too large and uneconomical. Moreover, the width | variety of the auxiliary iron plate pieces 1a-1d shall be 5-15 mm . When the width of the auxiliary iron plate pieces 1a to 1d is too wide, a strong peeling force is required, and the narrower the width, the weaker the peeling force is required. On the other hand, when making the desired auxiliary iron plate group 1 size. In addition, the number of auxiliary iron plate pieces 1a to 1d is increased, and it is troublesome.
[0009]
FIG. 2 is a cross-sectional view of a sticking auxiliary iron plate for magnet adsorption according to the present invention attached to the surface of a non-magnetic material. As can be seen from FIG. 2, the auxiliary iron plate pieces 1 a to 1 d are attached to the first double-sided pressure-sensitive adhesive tape 2 that is the same shape as the auxiliary iron plate group 1 or slightly smaller, with the end faces butting each other. The 1st double-sided adhesive sheet 2 is affixed on the single side | surface of the synthetic resin sheet 3 larger than it. The synthetic resin sheet 3 is affixed to one side of a second double-sided pressure-sensitive adhesive sheet 4 that can be repeatedly used with a urethane elastomer having the same shape as the synthetic resin sheet 3 as an adhesive.
[0010]
In FIG. 2, in order to peel off the second double-sided pressure-sensitive adhesive sheet 4 attached to one side of the non-magnetic material, the second double-sided pressure-sensitive adhesive sheet 4 is peeled off from the lower end portion side toward the auxiliary iron plate pieces 1d.
[0011]
Since the peeled-off pieces are integrated, they can be attached to the newly attached position, and the surface of the auxiliary iron plate group 1 that has been attached is formed flat.
[0012]
In the illustrated example, the shape of the auxiliary iron plate group 1 is rectangular, but it is needless to say that it may be circular (not shown). It should be noted that an appropriate bent portion may be formed on one end side of the auxiliary iron plate piece 1d so as to facilitate the peeling. (Not shown)
[0013]
【The invention's effect】
As described above, according to the present invention, as long as the second double-sided pressure-sensitive adhesive sheet attached to the surface of the nonmagnetic material is given a peeling force from the one end side toward the direction of the auxiliary iron plate pieces, It can be peeled off sufficiently with the power of the user. Since the plurality of auxiliary iron plate pieces are attached to the first double-sided pressure-sensitive adhesive sheet and are integrally connected even after the whole is peeled off in this way, it can be attached to a place where it is desired to reuse it. Since the surface of the auxiliary iron plate group at that time can be a flat surface, the attractive force of the magnet can be sufficiently exerted, and it is prevented from sliding off. In addition, since both the first and second double-sided pressure-sensitive adhesive sheets eliminate the exposed portion of the pressure-sensitive adhesive surface, it is possible to prevent contamination due to adhesion of dust or the like.
