Description

  The present invention relates to a wall surface fastener having an adhesive layer on the back side of the surface fastener.

  If you use a nail when you try to attach something to the wall, the nail removal work is complicated when you try to remove the attached object (hereinafter referred to as "attachment"). It will remain on the walls and attachments. Therefore, for example, when the attachment has a hook-and-loop fastener function such as a towel, it is considered to attach a wall fastener to the wall surface. As an example of a specific conventional surface fastener for a wall surface, there is one provided with an adhesive layer directly on the back surface of the surface fastener (Patent Document 1).

  Moreover, although it does not have a hook-and-loop fastener, a thermoplastic resin foam layer and a thermoplastic resin surface layer are laminated integrally as an example of a wall surface protective material related to the wall surface fastener in that it is attached to the wall surface. There exists a thing (patent document 2). And it is disclosed that this thermoplastic resin foam layer is stuck to a wall surface with an adhesive.

Utility Model Registration No. 3139262 Japanese Patent Laid-Open No. 2003-245992

  By the way, since the means for fixing the surface fastener to the wall surface is the adhesive layer, the wall surface fastener disclosed in Patent Document 1 can be peeled off from the wall surface and reattached to some extent. The adhesive layer and the hook-and-loop fastener are easily separated, and sometimes a part of the adhesive layer remains when peeled off from the wall surface. More specifically, the surface fastener includes an engaging element group including a large number of loops and hooks on one surface of the base material, and an adhesive layer is formed on the other surface of the base material. And since the other surface of a base material is a substantially plane, it can be said that the adhesion layer formed in this plane is easy to isolate | separate from a surface fastener.

  On the other hand, since the wall surface protective material of Patent Document 2 does not have a surface fastener, it cannot be used as it is as a wall surface fastener, but if a surface fastener is fixed on a thermoplastic resin surface layer, It can be used as a hook-and-loop fastener. However, since the wall surface fastener based on the wall surface protective material has no means for fixing to the wall surface and uses an adhesive different from itself, it is difficult to peel off the adhesive when it is bonded to the wall surface.

  The present invention was created in consideration of the above circumstances, and its purpose is to use a wall surface fastener that makes it difficult to separate the surface fastener and the adhesive layer while using the adhesive layer so that it can be reattached to the wall surface. Is to provide.

  The wall surface fastener of the present invention is a first surface fastener main body including a first base material and an engaging element group protruding from one surface of the first base material, and a sticking plate made of a foam and having a thickness thereof. One side of the direction is provided with a sticking plate on which the other side of the first base material is pasted, and an adhesive layer formed on the other side of the thickness direction of the sticking plate.

  The tackiness of the adhesive layer is not limited, but is preferably 2.0 or less.

  The engagement element group includes, for example, a hook group and a loop group, and is preferably a loop group.

  Moreover, although the thickness of the adhesion layer is not ask | required, it is desirable that it is 0.5-2.0 mm.

  According to the wall surface fastener of the present invention, a concave portion is formed by foam bubbles on the other surface of the sticking plate, and since the adhesive layer enters the concave portion, the connection strength between the sticking plate and the sticking layer is high. The adhesive layer and the hook-and-loop fastener are difficult to separate.

It is a front view which shows the surface fastener set for wall surfaces of 1st embodiment to which this invention was applied. It is the II-II sectional view taken on the line of FIG.

  The wall fastener set 1 according to the first embodiment to which the present invention is applied is attachable to and detachable from the wall fastener 2 and the wall fastener 2 as shown in FIGS. It comprises a plurality of attachments 3, 3,.

  The wall surface fastener 2 is formed on the first surface fastener main body 21, the adhesive plate 22 having the first surface fastener main body 21 attached to one surface in the thickness direction, and the other surface in the thickness direction of the adhesive plate 22. The adhesive layer 23 is provided.

The first hook-and-loop fastener body 21 is made of a fiber or a synthetic resin, and protrudes from a first base material 21a that is a cloth-like or plate-like shape serving as a base, and one surface in the thickness direction of the first base material 21a. And a loop group as the first engagement element group 21b.
The loop group 21b is composed of a number of loops 21c (rings), and the number of loops 21c protrudes from a number of positions on one surface of the first base material 21a.
Note that the first engagement element group may be a hook group 31b described later instead of the loop group 21b. However, since the loop group 21b has a better feel and appearance than the hook group 31b, the loop group 21b is preferably used as the first engagement element group.

The sticking plate 22 is made of a closed-cell or open-cell foam, and is a foam such as urethane, styrene, chloroprene, styrene butadiene, acrylic, vinyl chloride, polyethylene, isoprene, natural rubber, and preferably foamed plastic. It is.
The sticking plate 22 is plate-shaped and has a predetermined thickness t1. A specific value of the thickness t1 is 1.0 mm to 15.0 mm.
In addition, the 1st surface fastener main body 21 is affixed on the one surface of the thickness direction of the sticking board 22 with the adhesive agent. The adhesive strength of this adhesive is greater than that of the pressure-sensitive adhesive layer 23. Here, the one surface and the other surface of the sticking plate 22 are more precisely two surfaces intersecting in the thickness direction, and in the illustrated example, the sticking plate 22 has a plate shape having a uniform thickness. Two planes orthogonal to each other, in other words, two parallel planes.

  The adhesive layer 23 is formed by applying an adhesive to the sticking plate 22 and drying it. Since the sticking plate 22 is a foam, there are minute concave portions formed by bubbles of the foam on the two surfaces in the thickness direction of the sticking plate 22, and hence the two surfaces in the thickness direction are rough surfaces with irregularities. It becomes. A part of the pressure-sensitive adhesive layer 23 enters the rough surface, and the bonding strength between the pressure-sensitive adhesive layer 23 and the sticking plate 22 becomes strong.

Further, the adhesive layer 23 has a ball tack property indicating an adhesive strength of 2.0 or less. The ball tackiness measurement method conforms to the former JIS Z0237. A specific measurement method is as follows: for an inclined surface with an inclination angle of 30 degrees, the ball runway (length: 100 mm) from the upper side to the lower side of the inclined surface, and the adhesive layer 23 (length) as the measurement unit 100 mm) is formed continuously. Whether or not the steel balls of 2/32 inches to 32/32 inches (steel balls having different sizes in increments of 1/31 inches) are rolled on this inclined surface and stopped at the measurement section (adhesive layer 23). Is to be evaluated. Ball tackiness is expressed by the size of n / 32 of the stopped steel ball. In the measurement using the adhesive layer 23 used in the present invention, a 2/32 inch steel ball stopped, and a steel ball larger than that stopped. Therefore, the ball tackiness of the adhesive layer 23 is 2 (= 2.0) or less.
In the present embodiment, by setting the ball tackiness of the adhesive layer 23 to 2.0 or less, when the wall surface fastener 2 is peeled off from the wall surface W, the adhesive plate 22 and the adhesive layer 23 remain integrated. The surface fastener 2 can be separated from the wall surface W. That is, since the adhesive layer 23 is less likely to remain on the wall surface W, the wall surface W is less likely to become dirty.
On the other hand, if the ball tackiness is greater than 2.0, the adhesive strength becomes too strong, and when the wall surface fastener 2 is peeled from the wall surface W, the adhesive plate 22 and the adhesive layer 23 are separated, and the wall surface W There is a possibility that the adhesive layer 23 may remain.

The thickness t2 of the adhesive layer 23 is, for example, 0.5 to 2.0 mm. By the way, this figure is rounded off to the second decimal place.
In this embodiment, the adhesive plate 23 and the adhesive layer 23 are integrated when the wall surface fastener 2 is peeled off from the wall surface W by setting the thickness t2 of the adhesive layer 23 to 0.5 to 2.0 mm. The wall surface fastener 2 can be separated from the wall surface W. That is, since the adhesive layer 23 is less likely to remain on the wall surface W, the wall surface W is less likely to become dirty.
On the other hand, when the thickness t2 is smaller than 0.5 mm, the adhesive force is weakened, and the wall fastener 2 is peeled off from the wall surface W when the attachment 3 is peeled off from the wall fastener 2.
On the contrary, when the thickness t2 is larger than 2.0 mm, one surface of the adhesive layer 23 (adhesive surface to the wall surface W) is far from the adhesive plate 22 (bonding surface to the adhesive plate 22). When peeling off, the sticking plate 22 and the adhesive layer 23 may be separated, and the adhesive layer 23 may remain on the wall surface W.

  Each attachment 3 includes an attachment main body 32 and a second hook-and-loop fastener body 31 attached to the attachment main body 32. Further, in the illustrated example, there are three attachments 3, and when these three attachments 3 are described separately, for convenience, they are referred to as first, second, and third attachments 3a, 3b, and 3c. .

The second hook-and-loop fastener body 31 is made of fiber or synthetic resin and can be attached to and detached from the first hook-and-loop fastener main body 21. And a hook group as a second engagement element group 31b protruding from one surface in the thickness direction of the substrate 31a.
The hook group 31b can be attached to and detached from the loop group 21b of the first hook-and-loop fastener body 21, and is composed of a large number of hooks 31c. The large number of hooks 31c are formed from a large number of positions on one surface of the second base material 31a. It protrudes. Each hook 31c is J-shaped, protrudes from the second base material 31a, and is curved so as to be folded back while bulging in an arc shape on the tip side.

The attachment main body 32 is an object to which the second surface fastener main body 31 can be attached. In the illustrated example, the attachment body 32 is different for each of the first, second, and third attachments 3a, 3b, and 3c, and when these three attachment bodies 32 are described separately, For convenience, they are referred to as first, second, and third attachment bodies 33, 34, and 35.
The 1st attachment main body 33 adhere | attaches the surface of the thickness direction of the base plate 33b which consists of a foam on the surface of the thickness direction of the decorative board 33a made from a cork by the front view triangle shape. The other surface in the thickness direction of the second base material 31a of the second hook-and-loop fastener body 31 is adhered and pasted to the other surface in the thickness direction of the base plate 33b.
The second attachment main body 34 is a thin belt-like cloth, and the other surface of the second hook-and-loop fastener body 31 in the thickness direction of the second base material 31a is adhered and pasted to one surface of the cloth. It is.
The third attachment body 35 has a thick belt-like cloth 35a, a disk shape having a diameter wider than the band width of the cloth 35a, and connects the resin attachment plate 35b, the attachment plate 35b, and the fabric 35a. The connecting metal fitting 35c and the decorative metal fitting 35d fixed to the fabric 35a.

The wall surface fastener set 1 of the first embodiment of the present invention described above is used for a flat wall surface W that is a vertical surface as in the following 1) to 4).
1) First, the pressure-sensitive adhesive layer 23 of the wall surface fastener 2 is directed toward the wall surface W, and the loop group 21b of the wall surface fastener 2 is pressed by hand, whereby the pressure-sensitive adhesive layer 23 is firmly pressed against the wall surface W. The fastener 2 is attached to the wall surface W.
2) Next, the second hook-and-loop fastener body 31 of the attachment 3 is directed toward the wall surface fastener 2 affixed to the wall surface W, and the attachment body 32 of the attachment 3 is pushed by hand. The second hook-and-loop fastener main body 31 and the first hook-and-loop fastener main body 21 of the wall surface fastener 2 are connected, and the attachment 3 is attached to the wall surface fastener 2.
3) When the attachment 3 is removed, the attachment 3 is pulled away from the wall surface W without pressing the wall surface fastener 2 by hand. Then, only the attachment 3 is peeled off, and the wall surface fastener 2 remains adhered to the wall surface W. Accordingly, the adhesive strength (connection strength) of the adhesive layer 23 to the wall surface W is stronger (larger) than the connection strength of the first and second hook-and-loop fastener bodies 21 and 31. Thus, since only the attachment 3 is detached, the attachment 3 can be easily attached and detached.
4) When removing the wall surface fastener 2, the attaching plate 22 of the wall surface fastener 2 is pulled away from the wall surface W. Then, the bonding strength between the adhesive layer 23 and the adhesive plate 22 (foam) is strong, the ball tackiness of the adhesive layer 23 is 2.0 or less, and the thickness of the adhesive layer 23 is 0.5-2. Since the thickness is 0.0 mm, the wall surface fastener 2 is separated from the wall surface W while the adhesive plate 22 and the adhesive layer 23 are integrated.

  The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
