Description

  The present invention relates to a wall surface fixture provided with, for example, a hook for hanging, and more specifically to a wall surface fixture fixed to a wall surface by using a nail and an adhesive tape in combination.

  One of the tools for holding objects on the wall is a hanging tool. For example, as shown in Patent Document 1, the hanging tool includes a mounting board that is attached along the wall surface, and a hanging tool body that is attached to and detached from the mounting board. In this type of hanging tool, the mounting substrate is fixed to a wall surface via a nail or a double-sided adhesive tape.

  The fixing method using a nail is suitable for suspending a large suspended object because it can withstand a large load because it is firmly fixed to a wall surface. Also, PVC wallpaper cannot be attached with adhesive tape, so it had to be fixed with nails.

  However, the fixing method by nailing has the following problems. That is, for example, when a hanging tool is installed on a relatively soft wall such as mortar or gypsum board, the nail hole formed on the wall is enlarged due to repeated loads, and the nail may be loosened.

As one method of preventing this, in Patent Document 1, a part of the load is received by the adhesive tape by using the adhesive tape together. However, in Patent Document 1, a nail is driven into the adhesive tape. When removing, the nail must first be pulled out, and then the mounting board must be peeled off from the wall surface, so the area around the nail hole will be pulled up with adhesive tape, so the mounting board is peeled off. There was a risk that the wallpaper and the like would peel off at the same time.

Next, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is an exploded partial cross-sectional view showing a mounting state of a wall surface fixture according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view and a plan view of a base plate. Figure 3 is a modification of the position of the nail insertion holes of the base plate, FIG. 4 is a perspective view of a pressure-sensitive adhesive tape, FIG. 5 is a front view showing a modified example of the adhesive tape.

  As shown in FIG. 1, the wall surface fixture 1 includes a base plate 2 that is fixed to the wall surface W, and a fixture body 3 that is detachably attached to the base plate 2. In this example, the base plate 2 and the fixture body 3 are made of a synthetic resin molded product.

  In this example, the fixture body 3 is a so-called suspension tool in which a hook 31 for suspension is integrally formed on the front surface, but additional means such as a hook provided on the fixture body 3 are: This is an optional matter in the present invention.

  That is, various holders such as a clip may be provided in addition to the hook 31, and a hanger such as a towel hanger may be provided. The basic attachment structure is not particularly limited as long as it is the same as the present invention.

  In this example, the attachment body 3 is attached to the base plate 2 by sliding a part of the attachment body 3 on an engagement claw (not shown) provided on the base plate 2 so as to be engaged. However, the locking structure between the base plate 2 and the fixture body 3 is not particularly limited. Further, the base plate 2 and the fixture main body 3 may be integrated without being separated.

  Referring also to FIG. 2, the base plate 2 is formed of a rectangular plate and is provided with a nail insertion hole 21 into which the nail 5 is inserted. The nail insertion hole 21 is a through-hole penetrating in the thickness direction of the base plate 2 (left-right direction in FIG. 1), and is formed so as to insert the nail 5 diagonally downward from the front surface of the base plate 2 toward the back surface. ing.

  The nail insertion hole 21 is preferably provided with a stepped surface 22 for receiving the nail head 51 of the nail 5. In this example, the nail 5 is inserted into the nail insertion hole 21, but the present invention includes a screw as a similar product of the nail 5. That is, a method of fixing the base plate 2 by inserting a screw into the nail insertion hole 21 may be used.

  As shown in FIG. 2 (b), in this example, the nail insertion holes 21 are provided in two places up and down along the both sides of the front surface of the base plate 2, for a total of four locations. Is disposed so as to be out of the adhesive range of the adhesive tape 4.

  According to this, since the nail insertion hole 21 is arranged so as to be out of the adhesive tape 4 attachment range, the nail 5 is inserted when the nail 21 is inserted into the nail insertion hole 21 and driven into the wall surface W. Therefore, the adhesive tape 4 is not punched out, so that the adhesive tape 4 can be peeled off first.

  In this example, the nail insertion holes 21 are arranged at four locations on the left and right sides of the adhesive tape 4 sticking range, but may be provided so as to remove the sticking range of the adhesive tape 4 as shown in FIG. ) May be provided on the upper part of the base plate 2.

  Further, as shown in FIG. 3B, when the base plate 2 is wide and is fixed by using two adhesive tapes 4, the nails are removed so that the adhesive range of each adhesive tape 4 is removed. It is preferable to provide the insertion hole 21.

  With reference to FIG. 4, the structure of the adhesive tape 4 is demonstrated. The pressure-sensitive adhesive tape 4 is composed of a double-sided pressure-sensitive adhesive tape in which pressure-sensitive adhesive layers 42 and 42 are formed on both surfaces of a tape base material 41 having an appropriate rubber elasticity, and is gripped by one end in the stretching direction (longitudinal direction). A grip portion 43 is provided.

  In addition, although the release paper (not shown) which protects the adhesive layers 42 and 42 when not in use is provided on both surfaces of the adhesive tape 4, in the present invention, the configuration of the release paper may be arbitrary. The illustration and description are omitted.

The tape base material 41 is preferably a synthetic resin that is easily stretched and peeled and has appropriate rubber elasticity. In this example, the tape base material 41 is formed of a foamed sheet of a crosslinked polyolefin resin polymerized using a metallocene catalyst. The material may be arbitrarily selected according to the specification as long as it has appropriate rubber elasticity having releasability. The configuration of the foam sheet may be either open cells or closed cells.

  According to this, since the adhesive tape 4 itself has the stretching release property, when the adhesive tape 4 is pulled down with the base plate 2 fixed to the wall surface W, the adhesive tape 4 is stretched from the wall surface W. While being peeled off, the wall surface W can be removed without damaging as much as possible by removing the base plate 2 after removing the adhesive tape 2 first.

  In this example, the tape base material 41 is formed by forming both ends of a rectangular sheet having a predetermined thickness into a semicircular convex shape, but the shape of the tape base material 41 is arbitrary such as a rectangular shape, an elliptical shape, a triangular shape, etc. It is.

  The pressure-sensitive adhesive layers 42, 42 are highly retainable and are coated with a pressure-sensitive adhesive that can be synchronized with the crosslinked polyolefin resin of the tape base material 41. In this example, the pressure-sensitive adhesive is composed of a SBS block copolymer polymer applied uniformly and directly on the surface of the tape base 41 with a predetermined thickness. In this example, the pressure-sensitive adhesive layers 42 and 42 are formed to have a thickness of 0.1 mm.

  In this example, the PSA is based on an SBS block copolymer polymer, and an adhesive component such as α-pinene resin or C5C9 petroleum resin, naphthenic oil or the like is added to the matrix, and an antioxidant or ultraviolet absorber. Various additives such as are blended.

  More preferably, an isocyanate resin is further added to the pressure-sensitive adhesive. According to this, since it is strongly associated with the surface treatment of the tape substrate, the interfacial strength is further increased and the anchoring property can be improved.

  More preferably, the adhesive contains a predetermined amount of silica beads. In this example, since the pressure-sensitive adhesive is solvent-based, silica beads having solvent resistance are used. Of these, hydrophobic silica beads are more preferable because they have good dispersibility in the solvent-based pressure-sensitive adhesive material.

  The gripping portion 43 is made of a non-adhesive synthetic resin film bonded to both ends at one end in the extending direction of the tape base material 41. In this example, the gripping portion 43 is made of a polyester film bonded to the surface of the pressure-sensitive adhesive layers 42, 42, but if it is non-sticky for gripping by hand, for example, the pressure-sensitive adhesive layer on the tape base material 41. 42 and 42 may be formed without coating.

In this example, in order to prevent the adhesive tape 4 from being punched out by the nail 5, the nail insertion hole 21 of the base plate 2 is provided at a position outside the adhesive tape 4 attachment range. tape 4 may be stuck to the base plate 2 so as to avoid the peg insertion hole 21. Such an embodiment is also included in the present invention.

  That is, as shown in FIG. 5A, the adhesive tape 4 is provided with a notch 44 in which a part of the adhesive surface is notched so as to avoid the nail insertion hole 21 of the base plate 2. The notches 44 are cut in a semicircular shape so as to avoid the nail insertion holes 21 and are provided at two positions on the left and right sides.

  According to this, the nail 5 is prevented from penetrating the adhesive tape 4 by being pasted by the notch portion 44 so as to avoid the nail insertion hole 21.

  As an aspect other than this, as shown in FIG. 5 (b), a single slit groove 45 is provided from one end (the upper end in FIG. 5 (b)) to the center of the adhesive tape 2, and a nail is formed in the slit groove 45. The insertion hole 21 may be arranged.

  As another embodiment, as shown in FIG. 5 (c), a part of the adhesive tape 2 is cut out along the nail insertion hole 21, and one end of the adhesive tape 2 is connected so that the cut-out portions 46 are connected to each other. The same effect can be obtained by forming the cut 47 from the upper end in FIG.

  Further, as shown in FIG. 5 (d), two cut-out portions 46 may be arranged in parallel on the top of the adhesive tape 2, and a cut 47 may be provided from the front end of the adhesive tape 2 for each cut-out portion 46. You may make it connect.

  Next, an example of a procedure for using the wall surface fixture 1 will be described with reference to FIG. First, the release paper (not shown) of the adhesive tape 4 is peeled off, and the exposed adhesive surface is bonded along the back surface of the base plate 2.

  Next, the other release paper is peeled off, and the adhesive surface is attached to a predetermined position on the wall surface W. As a result, the base plate 2 is attached to the wall surface W. Next, the base plate 2 is completely fixed to the wall surface W by inserting the nail 5 into the nail insertion hole 21 and hitting the wall surface W with a hammer or the like.

  After attaching the fixture body 3 to the base plate 2, the object to be suspended may be suspended from the hook 31 and used. In removing the used hanger body 3, first, the attachment body 3 is removed from the base plate 2.

  Next, with the base plate 2 fixed to the wall surface W, the grip portion 43 of the adhesive tape 4 protruding from the lower end of the base plate 2 is gripped by hand and gradually pulled downward. As the adhesive tape 4 is pulled, it is gradually peeled off from the wall surface W. At this time, since the base plate is fixed by the nail, the base plate flies toward the hand simultaneously with the peeling of the adhesive tape. There is no going out.

  After peeling off the adhesive tape 4 from the wall surface W, the base plate 2 and the nail 5 can be removed simultaneously by pulling out the nail 5 with pliers or lifting the base plate 2 from the wall surface W. According to this, by removing the nail 5 after peeling off the adhesive tape 4, it is possible to prevent the wallpaper near the nail hole from being damaged by the adhesive tape as in the prior art.
