Description

  The present invention relates to a hook that is detachably attached to a wall surface via an adhesive on the back surface, and particularly relates to a measure that allows the hook to be easily peeled off from the wall surface.

  In general, a hook is known in which a hook body provided with a hook piece protruding from the lower end of the front surface is bonded to a wall surface via an adhesive on the back surface (see, for example, Patent Document 1). In this case, the adhesive is applied over the entire back surface of the hook body.

JP 2004-57456 A

  By the way, as this kind of hook, there is also a hook that is detachably bonded to a wall surface through an adhesive applied to the back surface of the hook body. In that case, when aiming at the removal | desorption performance of a hook, the non-application area | region of an adhesive agent may be provided in the whole lower end part of the back surface of a hook main body. In this case, when the hook is peeled off from the wall surface, the hook is easily lifted from the wall surface starting from the non-application area at the lower end of the back surface of the hook body.

  However, such a hook made of resin or metal is widely used, and any of them has a relatively high hardness. Therefore, when the hook is peeled off from the wall surface, the lower end of the hook body is peeled off from the wall surface. The peeling force at the force point (the lower end of the hook body) acts over the entire area from the lower end to the upper end of the adhesive application area. For this reason, considerable force is required when peeling off the hook body from the wall surface, which is a considerable burden for women and children, and the hook cannot be easily peeled off from the wall surface.

  The present invention has been made in view of such points, and the object of the present invention is to make the peeling force when peeling the hook from the wall surface act only on the peeling position in the adhesive application area. Thus, an object of the present invention is to provide a hook that reduces the force when the hook body is peeled off from the wall surface and can be easily peeled off from the wall surface.

  In order to achieve the above object, the present invention is premised on a hook in which a hook body provided with a hook piece protruding from the lower end of the front surface is detachably attached to a wall surface via an adhesive on the back surface. Furthermore, the non-application area | region of the said adhesive agent is provided in the whole lower end part of the back surface of the said hook main body. And it is characterized in that a deflection amount increasing portion is provided on the surface side of the hook body to increase the deflection amount of the hook body when the hook body is peeled off from the wall surface.

  Further, the bending amount expanding portion may be configured such that a region above the non-application region on the surface side of the hook main body is cut out to be a substantially uniform thin shape.

  On the other hand, even if the said bending amount expansion part is comprised by the groove-shaped part continuously recessedly provided across both right-and-left both ends in the area | region above the said non-application area | region in the surface side of the said hook main body. Good.

  Further, the deflection amount increasing portion may be configured such that the region above the non-application region on the surface side of the hook body is cut away and gradually becomes thinner toward the upper end of the hook body. .

  In short, by providing a deflection amount enlargement portion on the surface side of the hook body to enlarge the deflection amount of the hook body when peeling the hook body from the wall surface, the peeling force when peeling the hook from the wall surface is increased. When acting on the hook body, the amount of deflection of the hook body is increased. As a result, the peeling force when the hook is peeled off from the wall surface acts only on the peeling position in the adhesive application area by the hook body whose amount of flexure is increased accordingly, and when the hook body is peeled off from the wall surface. This greatly reduces the force and can easily remove the hook from the wall.

  In addition, the amount of deflection of the hook main body by the peeling force when the hook is peeled off from the wall surface is configured by cutting away the region above the non-application region so as to form a substantially uniform thin shape. The enlarged portion bends uniformly, and the peeling force can always be applied only to the peeling position of the adhesive application region.

  On the other hand, the upper portion of the non-application region is formed by a groove-shaped portion that is continuously recessed across the left and right ends, so that the bending amount expanding portion is configured to peel off when the hook is peeled off from the wall surface. The region above the non-application region of the hook body is bent by the force, and the peeling force can be efficiently applied to the starting point of the separation of the adhesive application region.

  Furthermore, by cutting away the region above the non-application region and configuring the flexure amount expanding portion so that it gradually becomes thinner toward the upper end of the hook body, the peeling force when peeling the hook from the wall surface The area above the non-application area of the hook body is gradually bent, and the force for peeling the hook body from the wall surface can be greatly reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  FIG. 1 is a side view of a hook according to a first embodiment of the present invention, FIG. 2 is a front view of the hook, and FIG. 3 is a plan view of the hook.

  1 to 3, reference numeral 1 denotes a hook according to the first embodiment of the present invention. Examples of the hook 1 include ABS resin, PC resin (polycarbonate), POM resin (polyacetal), PA resin, A resin product obtained by molding a hard resin such as PS resin (polystyrene), PVC resin, PP resin, or PE resin by injection molding or extrusion molding is used.

  The hook 1 includes a hook body 10 having a thickness of about 3 to 4 mm formed in a vertically long plate shape that is long in the vertical direction. The hook body 10 is chamfered in a substantially arc shape on both the left and right sides of the upper end, while the lower end is chamfered in a substantially arc shape. A hook piece 11 protruding from the lower end position is integrally provided on the surface of the hook body 10. The hook body 10 is bonded to a wall surface (not shown) by applying an adhesive (not shown) on the back surface thereof. In this case, the wall surface is formed of wallpaper made of paper, vinyl, olefin or the like that is more uneven than the mirror surface.

  4 is a rear view of the hook 1, and FIG. 5 is a cross-sectional view taken along line AA of FIG. As shown in FIG. 4, a display unit 12 that displays the application position of the adhesive is provided on the back surface of the hook body 10. As shown in FIG. 5, the display unit 12 has a substantially U-shaped cross section that has a substantially inverted U-shape that is connected in a single stroke so as to extend over almost the entire area except the lower end of the back surface of the hook body 10. It is formed by the groove 13.

  The groove 13 includes long straight portions 131 and 131 that extend in the vertical direction, and short straight portions that extend in the left and right directions, with the upper ends of both long straight portions 131 and 131 being connected to each other at the left and right ends via arc portions. 132. These straight portions 131 and 132 are disposed substantially in parallel with each other with a certain distance (for example, about 6.5 mm) with respect to the outer edges (right and left side edges and the upper edge) of the adjacent hook body 10. The straight portions 131 are also arranged with a certain distance (for example, about 7 mm) substantially the same as the distance to the left and right side surfaces. Further, the lower ends of both the long straight portions 131 and 131 are relatively separated from the lower end of the hook body 10 (for example, about 12 mm). Then, the adhesive is injected into the groove 13 (both the long straight portions 131 and 131 and the short straight portion 132) of the display unit 12 on the back surface of the hook body 10 in the manner of a single stroke, and the hook body 10 is attached to the wall surface. Even if it is compressed when worn and leaks out of the groove 13, it does not overflow from the outer edge of the hook body 10, and the hook body 10 looks good and is affixed to the wall surface.

  Further, a rib 14 extending in the left-right direction protrudes from the lower end portion of the back surface of the hook body 10. The rib 14 is provided at a position separated from the lower ends of the two long straight portions 131 and 131 by a certain distance (for example, about 6.5 mm), and is compressed when the hook body 10 is attached to the wall surface. A small amount (for example, about 0.3 mm) so that the adhesive leaking out from the lower ends of the straight line portions 131 and 131 can be reasonably blocked and the non-application area 15 where the adhesive is not applied can be reliably set below the rib 14. It protrudes.

  6A and 6B show a container of an adhesive applied to the back surface of the hook body 10, where FIG. 6A shows a state in which the tube mouth is closed with a cap, and FIG. 6B shows a state immediately before the tube mouth is opened with a cap projection. Respectively.

  As shown in FIGS. 6A and 6B, the adhesive is enclosed in the tube Y. This adhesive makes it possible to bond the back surface of the hook body 10 to the wall surface formed of wallpaper. As the adhesive, for example, “Pitat! And Peel” of Sharp Chemical Industry Co., Ltd. can be applied. As shown in FIG. 6A, the adhesive is discarded every time the hook body 10 is peeled off from the wall surface and applied to the back surface every time it is newly bonded. Only the application amount necessary for new bonding is filled in the individual tubes Y. In this case, as shown in FIG. 6B, when the tube Y is pressed while the mouth Yb of the tube Y is opened by the protrusion Yc on the top of the cap Ya, the adhesive in the tube Y is removed. The adhesive is injected from the mouth Yb and can be applied with a single stroke without being separated from the display unit 12, and the adhesive can be smoothly applied to the display unit 12.

  Further, below the ribs 14 on the back surface of the hook body 10, a protrusion 16 is provided that extends linearly in the left-right direction in the non-application region 15. The protrusion 16 has a slightly larger protrusion than the rib 14 and is set to a protrusion (for example, about 0.5 mm) that substantially matches the layer thickness of the adhesive that is compressed when the hook body 10 is attached to the wall surface. Has been.

  The surface side of the hook body 10 is a deflection amount that increases the deflection amount of the hook body 10 on the upper side that is a predetermined distance (for example, about 10 mm) away from the non-application area 15 when the hook body 10 is peeled off from the wall surface. An enlargement unit 17 is provided. The bending amount expanding portion 17 is configured to cut out a region away from the non-application region 15 by a predetermined distance (for example, about 10 mm) and to have a uniform thin wall shape. In this case, the deflection amount enlarged portion 17 is set to a thickness that is approximately one third of the thickness of the hook body 10.

  Therefore, in the present embodiment, the deflection amount enlargement portion 17 that enlarges the deflection amount of the hook body 10 above the non-application area 15 when the hook body 10 is peeled off from the wall surface on the surface side of the hook body 10. Therefore, when the peeling force when peeling off the hook 1 from the wall surface acts on the hook main body 10, the amount of deflection of the hook main body 10 on the upper side that is separated from the non-application area 15 by a predetermined distance (for example, about 10 mm). Enlarged. As a result, the peeling force when the hook 1 is peeled off from the wall surface acts only on the peeling position in the adhesive application region by the hook body 10 whose amount of deflection is increased accordingly, and the hook body 10 is removed from the wall surface. The force at the time of peeling is reduced, and the hook 1 can be easily peeled off from the wall surface.

  In addition, since the bending amount expanding portion 17 is formed by forming a region having a uniform thin shape all over a predetermined distance (for example, about 10 mm) above the non-application region 15, the hook 1 is peeled off from the wall surface. The peeling amount expanding portion 17 of the hook main body 10 is uniformly bent by the peeling force, and the peeling force can always be applied only to the peeling position in the adhesive application region.

  In the present embodiment, the hook body 10 is attached to the wall surface by the adhesive injected into the groove 13 of the display portion 12 on the back surface. However, as shown in FIG. Alternatively, an adhesive sheet 18 having a slight thickness may be adhered, and the adhesive sheet 18 may be repeatedly and detachably attached to a wall surface having no irregularities such as a mirror surface. The adhesive sheet 18 includes an acrylic foam adhesive layer whose surface is adhered to the back surface of the hook body 10, a polyurethane self-adhesive layer whose surface is adhered to the back surface of the acrylic foam adhesive layer, and an adhesive layer between the adhesive layers. A saturated polyester resin layer. When dirt or dust adheres to the back surface of the polyurethane self-adhesive layer, the adhesiveness is restored by washing with water or the like. Even in this case, when the peeling force when the hook 1 is peeled off from the wall surface acts on the hook main body 10, the amount of deflection of the hook main body 10 is increased on the upper side that is a predetermined distance away from the non-application area 15. As a result, the peeling force when the hook 1 is peeled off from the wall surface acts only on the peeling position of the bonding region of the adhesive sheet 18 by the hook body 10 whose amount of flexure is increased accordingly. The force at the time of tearing off is reduced, and the hook 1 can be easily peeled off from the wall surface.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  In this embodiment, the configuration of the hook body is changed. The rest of the configuration excluding the hook body is the same as in the case of the first embodiment, and the same parts are denoted by the same reference numerals and detailed description thereof is omitted. 8 is a side view of the hook according to the second embodiment of the present invention, FIG. 9 is a front view of the hook, and FIG. 10 is a plan view of the hook.

  That is, in the present embodiment, as shown in FIGS. 8 to 10, the hook body 20 of the hook 2 is above the non-application area 15 so that the surface thereof becomes thinner as it goes to the upper edge of the hook body 20. This region is cut out to constitute a bending amount expanding portion 21 formed in an arc shape toward the back surface side. The hook 2 is made of resin, and the hook body 20 is formed in a vertically long plate shape that is long in the vertical direction. Further, the hook piece 11 protrudes from a lower end position of a substantially perfect circular base 22 whose peripheral surface coincides with the lower end of the hook body 20.

  Therefore, in the present embodiment, the region above the non-application region 15 on the front surface side of the hook body 20 is cut away so as to gradually become thinner toward the upper edge of the hook body 20, and the circle toward the back surface side. Since the bending amount of the hook body 20 is increased by the bending amount expanding portion 21 formed in an arc shape, when the peeling force when the hook 2 is peeled off from the wall surface acts on the hook body 20, the upper edge of the hook body 20. As the distance approaches, the amount of deflection of the hook body 20 is increased. As a result, the peeling force when the hook 2 is peeled off from the wall surface gradually bends as it approaches the upper side of the non-application area 15 of the hook body 20, and the force when the hook body 20 is peeled off from the wall surface is greatly reduced. Thus, the hook 2 can be easily peeled off from the wall surface.

  Next, a third embodiment of the present invention will be described with reference to FIG.

  In this embodiment, the configuration of the hook body is changed. The rest of the configuration excluding the hook body is the same as in the case of the first embodiment, and the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

A bending amount expanding portion 31 that is cut out and expands in an arc shape on the surface side is formed. The hook 3 is made of resin, and the hook body 30 is formed in a vertically long plate shape that is long in the vertical direction. Further, since the hook piece 11 is formed with the surface of the hook body 30 bulging in an arc shape on the surface side, the thickness near the base is sufficiently secured, so that the hook piece 11 protrudes from the lower end position of the hook body 30. It is integrally formed.

  Therefore, in the present embodiment, the region above the non-application region 15 on the surface side of the hook body 30 is cut away so as to gradually become thinner toward the upper edge of the hook body 30 and is arcuate on the surface side. Since the deflection amount of the hook body 30 is increased by the bulging deflection amount enlargement portion 31, when the peeling force when the hook 3 is peeled off from the wall surface acts on the hook body 30, the hook becomes closer to the upper edge of the hook body 30. The amount of bending of the main body 30 is increased. As a result, the peeling force when the hook 3 is peeled off from the wall surface gradually bends as it approaches the upper side of the non-application area 15 of the hook body 30, and the force when the hook body 30 is peeled off from the wall surface is greatly reduced. Thus, the hook 3 can be easily peeled off from the wall surface.

In the present embodiment, the hook body 30 is configured with the bending amount expanding portion 31 that swells in an arc shape on the surface side so that the surface of the hook body 30 becomes thinner toward the upper edge of the hook body 30.

In this case, the peeling force when the hook 3 is peeled off from the wall surface is formed by forming the bending amount expanding portion 31 together with the groove-like portion 33 extending across the left and right ends in the region above the non-application region 15. When the hook body 30 is peeled off from the wall surface, the region above the non-application region 15 of the hook body 30 bends more efficiently and the peeling force acts efficiently on the starting point of the peeling of the adhesive application region. Thus, the hook 3 can be easily peeled off from the wall surface.

  Next, a fourth embodiment of the present invention will be described with reference to FIGS.
