Description

[Technical Field]

[0001] The present invention relates to a wall installation tool, a wall installation set using the same, and a wall installation method. [Background technology]

[0002] Various types of shelf fasteners have been proposed for attaching shelves to desired locations on walls and other surfaces. For example, a wall-mounted component, such as a shelf, is engaged with a shelf fastener fixed to a wall to install the shelf. However, in many of these cases, the shelf fastener remains exposed even after the shelf is installed, resulting in aesthetic problems. Furthermore, large screws or other fasteners are required to install the shelf fastener, which can leave holes in the wall after the shelf fastener is removed from the wall. For this reason, a shelf fastener 110, as shown in FIG. 26, has been proposed, which allows the shelf or other wall-mounted component to be attached to the wall with rivets and leaves the shelf fastener hidden after installation (see, for example, Patent Document 1).

[0003] As shown in Figure 26, shelf material fixture 110 is used by being fixed to a wall surface, and has insertion completion feeling portion 120 that extends upward and away from the wall surface from near the center of the upper side of shelf material fixture 110 fixed to the wall surface. By inserting insertion completion feeling portion 120 into receiving portion 210 of tray-equipped shelf material 200, tray-equipped shelf material 200 is attached to shelf material fixture 110. At this time, insertion completion feeling portion 120 emits a clicking sound, allowing the installer to know that installation is complete.

[0004] However, in the case of this shelf fixing device 110, the weight of the tray-equipped shelf material 200 must be supported only by the insertion completion sense generating section 120, which is not necessarily sufficient to prevent the tray-equipped shelf material 200 from falling off the wall on which it is installed (moving in the direction of gravity) and from moving away from the wall on which it is installed (moving in the cross direction), and this is particularly insufficient when a large static load or dynamic load is applied to the tray-equipped shelf material 200, and there was a problem in that it is not necessarily suitable for supporting shelves on which animals such as cats can walk.

[0005] [Patent Document 1] Japanese Patent Publication No. 2021-186393 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention aims to solve the above-mentioned problems of the prior art and to achieve the following objectives: That is, the present invention aims to provide a wall installation tool, a wall installation set using the same, and a wall installation method that can effectively prevent a wall installation member from falling off the wall (moving in the direction of gravity) and from moving away from the wall (moving in the intersecting direction) even when a large static load or dynamic load is applied to the wall, and that can easily, stably, and reliably install the wall installation member on the wall. [Means for solving the problem]

[0007] The means for solving the above problems are as follows: <1> A wall installation tool used to install a wall installation member on a wall, a wall fixing device fixed to the wall; and a wall fixing member fixing device fixed to the wall fixing member and abutting the wall fixing device to abut the wall fixing member against the wall, The wall fastener is a branched wall fixing portion fixed to a wall; a separation prevention means for preventing the wall mounting member fixture, which is fixed to the wall mounting member and abuts against the wall fixing device, from separating (separating) from the wall fixing device; a fall prevention means for preventing the wall mounting member fixture fixed to the wall mounting member and in contact with the wall fixing device from falling from the wall fixing device, The wall installation tool is characterized in that the separation prevention means is provided closer to the branched wall fixing portion than the fall prevention means.

[0008] The aforementioned <1> In the wall installation tool described in , the wall fixing device is fixed to the wall on which the wall installation member is to be installed by the branched wall fixing portion. The separation prevention means of the wall fixing device fixed to the wall prevents the wall installation member fixing device fixed to the wall installation member and in contact with the wall fixing device from separating from the wall fixing device. Furthermore, the drop prevention means of the wall fixing device fixed to the wall prevents the wall installation member fixing device fixed to the wall installation member and in contact with the wall fixing device from falling from the wall fixing device. Furthermore, since the separation prevention means is provided closer to the branched wall fixing portion than the drop prevention means, even if a large force is applied to the separation prevention means via the wall installation member fixing device fixed to the wall installation member and in contact with the wall fixing device, the wall fixing device is stably and reliably held to the wall by the branched wall fixing portion and is effectively prevented from separating from the wall. Furthermore, since the separation prevention means and the fall prevention means are located in different positions, the function of preventing the wall mounting member from separating from the wall and the function of preventing it from falling from the wall can be functionally separated, and even if a large force is applied to the wall mounting member, the wall fixing member is less likely to be damaged, and the wall mounting member is stably and reliably mounted on the wall.

[0009] <2> The wall fastener has a substantially rectangular base and a wide portion formed continuously with the base and wider than the base, The branched wall fixing portions of the wall fixing device are formed on each side of a pair of ends oriented in a direction substantially perpendicular to the width direction of the wide portion and protruding from the tip portion. The aforementioned <1> 1 is a wall installation tool according to the present invention.

[0010] The aforementioned <2> In the wall mounting tool described in , the wall fixing device has the base, the wide portion wider than the base, and the branched wall fixing portion having approximately the same width as the wide portion, arranged in this order. Therefore, the wall fixing device has a generally Y-shape when there are two branched wall fixing portions, and a generally fork-shape when there are three branched wall fixing portions. The branched wall fixing portions fix the wall fixing device to the wall at a width (spaced apart) wider than the base, so that the wall mounting member is stably and reliably mounted on the wall, and even if a large force is applied to the end of the wall mounting member in the width direction, the wall mounting member is effectively prevented from rattling or rotating. Furthermore, even if the wall mounting member installed on the wall falls off the wall, significant damage (such as destruction) to the wall is effectively prevented.

[0011] <3> In the wall fixing device, the separation prevention means is located at the wide portion and the fall prevention means is located at the base. <2> 1 is a wall installation tool according to the present invention. The aforementioned <3> In the wall mounting tool described in (1), the separation prevention means is located in the wide portion and near the branched wall fixing portion, so that even when a large force is applied to the end of the wall mounting member that is located away from the wall, the wall mounting member is effectively prevented from separating from the wall. Furthermore, since the fall prevention means is located in the base portion and lower than the separation prevention means, if the wall mounting member has a shelf or the like substantially perpendicular to the wall, the wall to which the shelf or the like is in contact serves as the fulcrum, the shelf or the like serves as the force point, and the position of the fall prevention means serves as the point of application. By the principle of leverage, the position of the fall prevention means on the wall fixing member is pushed toward the wall, and the downward (gravitational) force applied from the wall mounting member is received and supported by the fall prevention means. As a result, the wall mounting member is effectively prevented from falling from the wall. Furthermore, the separation prevention means and the fall prevention means are located in different positions, specifically the separation prevention means is located at the top and the fall prevention means is located at the bottom, and the function of preventing the wall mounting member from separating from the wall and the function of preventing it from falling from the wall are functionally separated.Therefore, even if a large force is applied to the wall mounting member, the wall fixing member is less likely to be damaged, and the wall mounting member is stably and reliably mounted on the wall.

[0012] <4> The fall prevention means of the wall fixing device is a protrusion protruding from the surface of the base of the wall fixing device. <2> 1 is a wall installation tool according to the present invention. The aforementioned <4> In the wall installation tool described in , the convex portion protrudes from the surface of the base, so that when the wall fixing device is fixed to the wall, the convex portion protrudes from the wall. As a result, the convex portion restricts downward (gravity direction) movement of the wall installation member fixing device fixed to the back surface of the wall installation member, and the convex portion receives and supports a load applied to the wall installation member via the wall installation member fixing member.

[0013] <5> The separation prevention means of the wall fixing device is positioned so as to overlap at least a portion of the wall fixing device when the wall fixing member is installed on the wall, and the portion of the wall fixing device is positioned closer to the wall than the wall fixing device, thereby preventing the wall fixing device from separating from the wall. <1> 1 is a wall installation tool according to the present invention.

[0014] The aforementioned <5> In the wall installation tool described in , when the wall installation tool is installed on a wall, the wall installation member fastener fixed to the back surface of the wall installation member is prevented from moving away from the wall by the separation prevention means of the wall fastener. As a result, the wall installation member installed on the wall is effectively prevented from separating from the wall.

[0015] <6> The branched wall fixing portion of the wall fixing device has a plurality of rivet holes into which rivets are inserted, and at least two of the rivet holes can be inserted with rivets in directions different from each other. <1> 1 is a wall installation tool according to the present invention.

[0016] The aforementioned <6> In the wall installation tool described in (1), at least two of the multiple rivet holes provided in the branched wall fixing portion of the wall fixing device can be inserted with rivets in different directions, so that the at least two rivets inserted into the rivet holes function like multidirectional pegs and exhibit high resistance to forces in a direction approximately perpendicular to the wall (a direction away from the wall). Therefore, the wall fixing device fixed to the wall does not easily come off the wall, and the wall installation member is installed stably and reliably. Furthermore, even when the wall fixing device is removed from the wall, only pinhole marks from the rivets remain on the wall, and no noticeable damage is caused to the wall. Furthermore, even if a wall installation member, such as a shelf, fixed to the wall falls off the wall, only pinhole marks from the rivets remain on the wall, and no noticeable damage is caused to the wall.

[0017] <7> The branched wall fixing portion has three of the rivet holes, When the straight line connecting two of the three rivet holes is the base of a triangle, the remaining one is the vertex relative to the base of the triangle and is located on the tip side of the branched wall fixing portion, The remaining one rivet hole can insert a rivet toward the base side of the triangle, The two rivet holes are capable of receiving rivets that are generally parallel to the base and that are spaced apart from each other. <6> 1 is a wall installation tool according to the present invention.

[0018] The aforementioned <7> In the wall mounting tool described in (1), the rivet inserted into the remaining rivet hole, which can be inserted toward the base of the triangle, provides a large resistance to downward (gravity direction) forces. Furthermore, the rivets inserted into the two rivet holes, which can be inserted toward the base and away from each other, provide a large resistance to forces in a direction approximately perpendicular to the wall (a direction of separation). In other words, because the three rivets function as a three-sided stake, the wall fixing device fixed to the wall does not easily come off the wall, ensuring stable and reliable installation of the wall mounting member. Furthermore, when the wall fixing device is removed from the wall, only pinhole marks from the rivets remain on the wall, and no noticeable damage is caused to the wall. Furthermore, even if a wall mounting member, such as a shelf, fixed to the wall falls off, only pinhole marks from the rivets remain on the wall, and no noticeable damage is caused to the wall.

[0019] <8> The wall mounting member fixing device is When a portion of the wall mounting member fastener overlaps with the base of the wall fastener and is positioned in contact with the protrusion formed on the surface of the base, a counter restricting portion that faces the branched wall fixing portion so as to cover the periphery of the branched wall fixing portion of the wall fixing device, and that restricts movement of the wide portion of the wall installation member fixing device in the width direction by the branched wall fixing portion; <2> 1 is a wall installation tool according to the present invention.

[0020] The aforementioned <8> In the wall mounting tool described in (1), when the wall mounting member fastener fixed to the back surface of the wall mounting member is attached to the wall fixing device fixed to the wall, a portion of the wall mounting member fastener overlaps the base of the wall fixing device and abuts against the protrusion formed on the surface of the base. In this case, the opposing restricting portion of the wall mounting member fastener faces the branched fixing portion of the wall fixing device so as to cover the periphery of the branched fixing portion, effectively preventing movement of the wall mounting member in its width direction (lateral direction, horizontal direction). Furthermore, the wall mounting member fastener eliminates the need to form a hole having the same outer shape as the wall fixing member on the wall surface side (back side) of the wall mounting member, such as a shelf.

[0021] <9> The wall mounting member fixing device is A substantially rectangular frame member having a pair of first linear portions A, B that are substantially parallel and opposed to each other, and a pair of second linear portions C, D that are substantially parallel and opposed to each other, wherein the pair of second linear portions C, D are formed to be continuous with the first linear portions A, B in a direction perpendicular to the pair of first linear portions A, B, the first linear portion A has an extension portion extending to the inside of the substantially rectangular frame member, The separation prevention means of the wall fixing device is positioned so as to overlap with the extension portion of the wall mounting member fixing device when the wall fixing member is installed on the wall, and the extension portion of the wall mounting member fixing device is positioned closer to the wall than the wall fixing device, thereby preventing the wall mounting member fixing device from separating from the wall. <8> The wall mounting fixture is as described above.

[0022] The aforementioned <9> In the wall installation tool described above, when the wall fixing member is installed on a wall, the separation prevention means in the wall fixing tool effectively prevents the wall installation member fixing tool from separating (moving away) from the wall.

[0023] <10> The separation prevention means of the wall fixing device is engageable with the extension portion of the wall fixing member fixing device when the wall fixing member is installed on the wall. <9> 1 is a wall installation tool according to the present invention.

[0024] The aforementioned <10> In the wall installation tool described in , the separation prevention means of the wall fixing device can engage with the extension portion of the wall installation member fixing device when the wall fixing member is installed on the wall. When the wall installation member fixing device fixed to the back surface of the wall installation member is attached to the wall fixing device fixed to the wall, a clicking sensation occurs due to the engagement of the separation prevention means with the extension portion, allowing the installer to easily understand that installation is complete. Furthermore, the extension portion is effectively prevented from detaching from the separation prevention means.

[0025] <11> The outer surfaces of both ends of the first linear portion B of the wall installation member fastener are positioned farther from the first linear portion A than the outer surface of the central portion of the wall fastener that can come into contact with the protrusion. <9> 1 is a wall installation tool according to the present invention.

[0026] The aforementioned <11> In the wall mounting device described in , the outer surfaces of both ends of the first linear portion B of the wall mounting member fastener are located farther from the first linear portion A than the outer surface of the central portion that can abut against the convex portion of the wall fastener. In other words, when the wall mounting member is mounted on a wall, the outer surfaces of both ends of the first linear portion B of the wall mounting member fastener are located lower than the outer surface of the central portion that can abut against the convex portion of the wall fastener. Therefore, the wall fasteners arranged inside the wall mounting member fastener further restrict lateral (horizontal) movement of the wall mounting member fastener. Therefore, even when a dynamic load, particularly in the lateral (horizontal) direction, is applied to the wall mounting member, rattle or the like does not occur.

[0027] <12> The aforementioned <1> from <11> a wall installation tool according to any one of the items (1) to (4), a wall installation member that is installed on a wall by the wall installation tool; The wall installation set is characterized by having:

[0028] The aforementioned <12> In the wall installation set described in the item (1), the wall installation member to be installed on the wall by the wall installation tool is <1> from <11> The wall mounting device is mounted on a wall by the wall mounting tool described in any one of the items (1) to (5). The wall fixing device is fixed to the wall on which the wall mounting member is to be installed by the branched wall fixing portion. The separation prevention means of the wall fixing device fixed to the wall prevents the wall mounting member fixing device fixed to the wall mounting member and in contact with the wall fixing device from separating from the wall fixing device. Furthermore, the drop prevention means of the wall fixing device fixed to the wall prevents the wall mounting member fixing device fixed to the wall mounting member and in contact with the wall fixing device from falling from the wall fixing device. Furthermore, since the separation prevention means is provided closer to the branched wall fixing portion than the drop prevention means, even if a large force is applied to the separation prevention means via the wall mounting member fixing device fixed to the wall mounting member and in contact with the wall fixing device, the wall fixing device is stably and reliably held on the wall by the branched wall fixing portion and is effectively prevented from separating from the wall. Furthermore, since the separation prevention means and the fall prevention means are located in different positions, the function of preventing the wall mounting member from separating from the wall and the function of preventing it from falling from the wall can be functionally separated, and even if a large force is applied to the wall mounting member, the wall fixing member is less likely to be damaged, and the wall mounting member is stably and reliably mounted on the wall.

[0029] <13> The wall mounting member has a shelf member that is positioned in a direction substantially perpendicular to the wall surface when the wall mounting member is mounted on the wall surface. <12> 1 is a wall installation set according to the present invention. The aforementioned <13> In the wall mounting set described above, the wall mounting member has a shelf material that is positioned approximately perpendicular to the wall surface when installed on the wall, so that the shelf material is stable and does not wobble even when objects are placed on it.

[0030] <14> The wall-hanging member is a shelf for a catwalk. <13> 1 is a wall installation set according to the present invention. The aforementioned <14> In the wall installation set described above, the wall installation member is a catwalk shelf, so even if an animal such as a cat walks on the catwalk shelf, particularly if an animal such as a cat moves laterally on the catwalk shelf and a dynamic load is applied to the catwalk shelf, the wall installation member will not rattle.

[0031] <15> The aforementioned <11> A method for installing a wall mounting member on a wall using the wall mounting set described in In the wall installation tool, the wall fixing device is fixed to the wall so that the branched wall fixing portion faces upward, and the wall installation member fixing device is fixed to the back surface of the wall installation member, This wall installation method is characterized in that the back surface of the wall installation member fixing device is abutted against the wall at a position above the branched wall fixing portion of the wall fixing device, and then slid downward, so that the wall installation member fixing device abuts against the separation prevention portion and the fall prevention portion of the wall fixing device.

[0032] The aforementioned <15> In the wall installation method described in , the wall fixing device of the wall installation tool is fixed to the wall with the branched wall fixing portion facing upward, and the wall installation member fixing device is fixed to the back surface of the wall installation member. Then, the back surface of the wall installation member fixing device is abutted against the wall at a position above the branched protrusion of the wall fixing device and then slid downward so that the wall installation member fixing device abuts against the separation prevention portion and the fall prevention portion of the wall fixing device. As a result, the wall installation member is installed on the wall.

[0033] <16> The wall fixing device in the wall installation tool is fixed to the wall by The wall mounting member is then brought into contact with the wall, with the separation prevention portion and the fall prevention portion of the wall fixing device being brought into contact with the wall mounting member fixing device fixed to the rear surface of the wall mounting member. <15> This is a wall installation method described in

[0034] The aforementioned <16> In the wall installation method described above, the wall fixing device in the wall installation tool is fixed to the wall by abutting the wall installation member against the wall with the separation prevention portion and the fall prevention portion of the wall fixing device abutted against the wall installation member fixing device fixed to the back surface of the wall installation member in advance. Therefore, there is no need to position the wall fixing device beforehand and fix it to the wall, and the wall fixing device is fixed to the wall when the wall installation member is abutted against the wall. [Effects of the Invention]

[0035] According to the present invention, it is possible to solve the above-mentioned problems in the prior art and achieve the above-mentioned object, and it is possible to provide a wall installation tool, a wall installation set using the same, and a wall installation method which can effectively prevent a wall installation member from falling off the wall (moving in the direction of gravity) and from moving away from the wall (moving in the intersecting direction) even when a large static load or dynamic load is applied to the wall installation member, and which can easily, stably, and reliably install the wall installation member on the wall.

[0037] (Wall installation tool, wall installation set using the tool, and wall installation method) The wall installation tool of the present invention comprises a wall fixing device and a wall installation member fixing device, and may further comprise other members appropriately selected depending on the purpose, such as rivets (push pins) for fixing the wall fixing device and the wall installation member fixing device, and an installation tool for attaching the rivets (push pins).

[0038] The wall installation set of the present invention comprises the wall installation tool of the present invention and a wall installation member (sometimes referred to as a "wall hanging member") that is installed on a wall by the wall installation tool, and may further comprise other members appropriately selected depending on the purpose, such as rivets (push pins) for fixing the wall installation tool and the wall installation member, and mounting tools for attaching and detaching the rivets (push pins).

[0039] The method for installing a wall-mounting member on a wall of the present invention is a method for installing a wall-mounting member on a wall using the wall-mounting set of the present invention. The wall fixing device and the wall mounting member fixing device can be fixed to a wall, shelf, or other wall mounting member using the rivets (push pins), but may also be fixed to a wall, shelf, or other wall mounting member using screws, etc., if necessary. However, it is preferable to fix the wall fixing device to the wall using the rivets (push pins) to prevent large holes from being created in the wall when the wall fixing device is removed.

[0040] The tack is not particularly limited and can be selected appropriately depending on the purpose, but examples include push pins and thumb tacks that have a needle part and a tack head for applying force to insert the needle part. The term "fixing device" in the wall fixing device and the term "fixing device" in the wall installation member fixing device are sometimes referred to as "mounting device," "locking device," etc.

[0041] The wall-mounted member (wall-hanging member) is not particularly limited in terms of shape, size, material, number, structure, etc., as long as it can be mounted on a wall, and can be appropriately selected depending on the purpose. Examples include a box-shaped shelf with a storage function, an L-shaped shelf with a platform that is installed horizontally against the wall, a catwalk shelf for animals such as cats to climb on, a three-dimensional structure such as a wall-hanging interior, and a two-dimensional structure such as a mirror or a painting.

[0042] According to the present invention, even wall installation members to which a large load is applied, such as catwalk shelves, can be firmly and stably installed on a wall using the wall installation tool of the present invention without causing rattles, etc. In the present invention, the term "catwalk shelf" is not limited to a shelf for cats, but refers to a shelf for all animals to climb on.

[0043] The size of the wall installation tool can be selected appropriately depending on the size and shape of the wall installation member (wall hanging member) to be installed on the wall, but from the viewpoint of aesthetics, it is preferable that the size be such that the entire wall installation tool is hidden by the wall installation member (wall hanging member) when the wall installation member (wall hanging member) is attached to the wall installation tool.

[0044] The material of the wall installation tool is not particularly limited and can be appropriately selected depending on the purpose, but resin is preferred because it is easy to mold and can be mass-produced. The resin is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include polyacetal (POM) resin, high impact polystyrene (HIPS) resin, polycarbonate resin, polyvinyl chloride resin, polyethylene resin, polypropylene resin, acrylonitrile-butadiene-styrene copolymer (ABS) resin, etc. Among these, polyacetal (POM) resin is preferred from the viewpoints of dimensional stability, strength, oil resistance, and fatigue resistance.

[0045] The number of wall mounting fixtures can be selected appropriately depending on the size and shape of the wall mounting member (wall-hanging member) to be mounted, but one wall mounting member may be mounted with one wall mounting fixture, or one wall mounting member may be mounted using two or more wall mounting fixtures.

[0046] The wall on which the wall installation member (wall-hanging member) is installed using the wall installation tool is a member that comes into contact with the surface on which the shelf material is fixed. The wall is not limited to a wall erected parallel to the direction of gravity as long as it is on a flat surface, but also includes, for example, a floor surface, a ceiling surface, a column surface, a beam surface, a door surface, and the like.

[0047] The material of the wall is not particularly limited and can be appropriately selected depending on the purpose, and may be, for example, a board, a plasterboard, a concrete wall, a tile wall, or the like. Here, an embodiment of the wall installation tool, a wall installation set using the same, and a wall installation method according to the present invention will be described with reference to the drawings. Note that the following is merely an embodiment, and the present invention can be modified as desired.

[0048] Fig. 1 is a schematic explanatory diagram showing an example of a wall installation tool of the present invention. The wall installation tool 1 shown in Fig. 1 has a wall fixing device 10 and a wall installation member fixing device 50. Fig. 1 does not show the wall to which the wall fixing device 10 is fixed, or rivets (push pins) for fixing the wall fixing device 10 to the wall. Fig. 1 also does not show the wall installation member (wall-hanging member) such as a shelf to which the wall installation member fixing device 50 is fixed, or the rivets, screws, etc. for fixing the wall installation member fixing device 50 to the wall installation member. There are no particular limitations on the rivets (push pins), screws, etc., and they can be selected appropriately depending on the purpose.

[0049] As shown in Figures 3 and 4, the wall mounting member fixing device 50 is fixed to a recess 102 provided on the back of the back material 101 of a wall mounting member 100 (here, a catwalk shelf material) which has a shelf board 104, a back material 101 arranged perpendicular to the shelf board 104, and a shelf board support member 105 connecting the shelf board 104 and the back material 101, by inserting a screw 21 into the screw hole 53.

[0050] Figure 2 is a diagram showing an example of the operation when setting up the wall installation tool shown in Figure 1. The wall installation tool fixture 50, which is a square frame-shaped member, is placed so that it covers the periphery of the wall fixture 10 fixed to the wall, with the back surface of the wall installation member (wall-hanging member) such as a shelf abutting against the wall, and is then slid in the direction of the arrow (downward) in Figure 2 until the wall fixture 10 and wall installation member fixture 50 abut against each other as shown in Figure 1, thereby allowing the wall installation member (wall-hanging member) such as a shelf fixed to the wall installation tool fixture 50 to be installed on the wall (details will be described later).

[0051] As shown in Figures 5 to 7, the wall fixing device 10 has a rectangular base 11, a wide portion 12 that is formed contiguous with the base 11 and is thicker and wider than the base 11, and a branched wall fixing portion 13 that is formed contiguous with the wide portion 12 and protrudes from the wide portion 12 in a branched manner, having a thickness thinner than the wide portion 12 and approximately the same thickness as the base 11. Here, a pair (two) of branched wall fixing portions 13 protrude from the wide portion 12, and the wall fixing device 10 has a substantially Y-shaped appearance in plan view. The number of branched wall fixing portions 13 may be three or more (if the number of branched wall fixing portions 13 is three, the wall fixing device 10 has a fork-like shape in plan view).

[0052] The branched wall fixing portion 13 has a branched protruding portion surface 13A having three rivet holes 13E formed therein for inserting rivets (push pins) 20 in different directions to fix the wall fixing device 10, a tip portion 13B located at the tip of the branched protruding portion surface 13A and in a direction approximately perpendicular to the branched protruding portion surface 13A, an inner edge portion 13C that communicates with tip portion 13B and faces other branched wall fixing portions 13, and an outer edge portion 13D that communicates with tip portion 13B and faces inner edge portion 13C.

[0053] When the straight line connecting two of the three rivet holes 13E forms the base of a triangle, the remaining rivet hole 13E is located as the apex of the triangle relative to the base and on the tip side of the branched wall fixing portion 13. This remaining rivet hole 13E, i.e., the rivet hole 13E formed near the center of the tip portion 13B of the branched wall fixing portion 13, allows a rivet (push pin) 20 to be inserted downward into the wall on which the wall mounting member 100 is to be installed. Therefore, when the load of the wall mounting member 100 is applied downward to the wall fixing device 10, that is, when a large load is applied to the tip portion 13B of the branched wall fixing portion 13 of the wall fixing device 10, the rivet (push pin) 20 inserted downward into the wall on which the wall mounting member 100 is to be installed directly below the tip portion 13B can exhibit great durability.

[0054] Furthermore, the two rivet holes 13E, i.e., the two rivet holes 13E located below the rivet hole 13E formed near the center of the tip end 13B of the branched wall fixing portion 13, allow rivets (push pins) 20 to be inserted substantially parallel to each other and in directions away from each other. Therefore, the three rivets (push pins) 20 inserted into these two rivet holes 13E and the rivet hole 13E located at the vertices of the triangle are inserted into the wall close to each other like a three-pronged stake, and therefore can demonstrate great durability when the load of the wall mounting member 100 is applied downward (in the direction of gravity) or horizontally to the wall fixing device 10, and the wall mounting member 100 can be firmly and stably installed (held) on the wall even when a large static load or dynamic load is applied to the wall mounting member 100.

[0055] In addition, the branched wall fixing portion 13 has a branch base 15 at the end of the wide portion 12 between a pair (two) of branched wall fixing portions 13, which accommodates an extension portion 52 in the wall mounting member fixing device 50 described later and is engageable with the extension portion 52.

[0056] As shown in Figure 6, when the wall fixing device 10 is fixed to a wall, the branch base 15 forms a space between itself and the wall. The branch base 15 has a storage section 15B, a bottom 15C, and an engaging protrusion 15A. The storage section 15B can store the extension section 52 of the wall mounting member fixing device 50. When the wall fixing device 10 is fixed to a wall with the branched wall fixing section 13 positioned upward, the bottom section 15C becomes the bottom surface of the storage section 15B and also serves as the end section of the wide section 12 on the branched wall fixing section 13 side. The engaging protrusion 15A is located closer to the branched wall fixing section 13 than the bottom section 15C and is spaced apart from the bottom section 15C, and can engage with the extension section 52 of the wall mounting member fixing device 50. The branch base 15 restricts the movement of the extension portion 52 of the wall-mounting component fastener 50 in a direction away from (moving away from) the wall, and therefore the branch base 15 functions as the aforementioned separation prevention means.

[0057] The engaging protrusions 15A here have a convex stripe shape formed substantially parallel to the width direction of the wall fastener 10 (substantially parallel to the tips of the branched wall fastening portions 13 and the tips of the branch base portions 15), but they may have any shape as long as they can engage with the extension portions of the wall installation member fastener 50, and may be, for example, a convex portion, a concave portion, a concave groove, or a combination of these. A plurality of engaging protrusions 15A may be provided at intervals. The cross-sectional shape of the convex stripe shape here is trapezoidal, but may also be, for example, semicircular, elliptical, triangular, rectangular, etc.

[0058] The wide portion 12 has a wide portion surface 12A formed approximately near the center with a rivet hole 12F for inserting a rivet (push pin) 20 to fix the wall fixing device 10 and a recess 12B capable of accommodating the head of the rivet (push pin) 20, a screw hole 12C for fixing the wall fixing device 10 to a wall with a screw or the like, an inclined portion 12D that is continuous with the base 11 and gradually becomes thinner toward the base 11, and an inclined portion 12E that is continuous with the branched wall fixing portion 13 and gradually becomes thinner toward the branched wall fixing portion 13.

[0059] The base 11 has a protrusion 14 and a recess 11B. The protrusion 14 is formed on the base surface 11A and protrudes linearly from the base surface 11A in the width direction of the base 11. Therefore, when the wall fixing device 10 is fixed to a wall, the protrusion 14 is positioned to protrude from the wall. The recess 11B can accommodate a rivet hole 11C for inserting a rivet (push pin) 20 and a rivet head 20a of the rivet (push pin) 20, which are formed on the base surface 11A and closer to the end of the base 11 than the protrusion 14.

[0060] Here, the side surface of the protrusion 14 that is positioned on the wide portion 12 side in a direction substantially perpendicular to the base surface 11A is the load-receiving surface 14B. The load-receiving surface 14B of the protrusion 14 restricts downward (gravity direction) movement of the wall-mounting-component fastener 50 fixed to the back surface of the wall-mounting member 100, and also receives and supports the load applied to the wall-mounting member 100 via the wall-mounting-component fastener 50. Therefore, the protrusion 14 (load-receiving surface 14B of the protrusion 14) functions as the aforementioned falling-off prevention means.

[0061] The rivet holes 11C allow rivets (push pins) 20 to be inserted downward into the wall on which the wall mounting member 100 is to be installed. Therefore, when the load of the wall mounting member 100 is applied downward to the wall fastener 10, that is, when a large load is applied to the load receiving surface 14B of the protrusion 14 of the wall fastener 10, the rivets (push pins) 20 inserted downward into the wall on which the wall mounting member 100 is to be installed directly below the load receiving surface 14B can exhibit great durability.

[0062] When the AA cross section of the wall fixture 10 in FIG. 8 is viewed in the direction of the arrows, it appears as shown in FIG. 9; when the BB cross section of FIG. 8 is viewed in the direction of the arrows, it appears as shown in FIG. 10; when the CC cross section of FIG. 8 is viewed in the direction of the arrows, it appears as shown in FIG. 11; and when the DD cross section of FIG. 8 is viewed in the direction of the arrows, it appears as shown in FIG. 12.

[0063] Although the wall fixture 10 is made of resin here, there is no particular limitation on the material, and it may be made of metal, wood, etc. The size of the wall fixture 10 can be selected appropriately depending on the size of the wall-mounted member 100 such as a shelf material.

[0064] As shown in FIGS. 13 and 14, the wall-mounting component fastener 50 is a substantially rectangular frame-shaped component 51 having a first linear portion A 51A, a first linear portion B 51B, a second linear portion C 51C, and a second linear portion D 51D. The pair of first linear portion A 51A and first linear portion B 51B faces each other substantially parallel. The pair of second linear portion C 51C and second linear portion D 51D faces each other substantially parallel. The pair of second linear portion C 51C and second linear portion D 51D is substantially perpendicular to the pair of first linear portion A 51A and first linear portion B 51B and is formed continuously with the first linear portion A 51A and first linear portion B 51B.

[0065] The wall-mounting-member fastener 50, which is a substantially rectangular frame-shaped member 51, is fixed to the recess 102 on the back surface of the wall-mounting member 100 so that, when the wall-mounting member 100 is installed on a wall, the pair of first linear portions A 51A and first linear portion B 51B, which are substantially parallel and opposed to each other, are positioned horizontally, and the pair of second linear portions C 51C and second linear portion D 51D, which are substantially parallel and opposed to each other, are positioned vertically (see FIGS. 3 and 4).

[0066] In the wall mounting member fixture 50, the wall mounting member fixture front surface 50A shown in FIG. 13 is the surface exposed on the back surface of the wall mounting member 100, and the wall mounting member fixture back surface 50B shown in FIG. 14 is the back surface that abuts against the back surface of the wall mounting member 100 (see FIGS. 3 and 4).

[0067] The substantially rectangular frame member 51 has screw holes 53 at its four corners. The first linear portion A 51A has an extension portion 52 that extends in a substantially rectangular shape inside the substantially square frame member 50 toward the first linear portion B 51B side.

[0068] A step is formed on the tip side of the extension portion 52, making it thinner so that it can enter the branch base 15 of the wall fixing device 10. An engagement protrusion 52C that can engage with the engagement protrusion 15A of the branch base 15 of the wall fixing device 10 is formed on the tip of the extension portion 52, and when the engagement protrusion 52C of the extension portion 52 is received in the receiving portion 15B of the branch base 15 of the wall fixing device 10 and engages with the engagement protrusion 15A, as shown in Figure 6, a click is generated. This allows the installer of the wall mounting member 100 to easily understand that installation is complete.

[0069] The engaging protrusion 52C here has a ridge shape formed substantially parallel to the width direction of the wall-mounting-component fastener 50 (substantially parallel to the first linear portion A 51A), but it may have any shape as long as it can engage with the engaging protrusion 15A of the wall fastener 10, and may be, for example, a protrusion, a recess, a recessed groove, or a combination of these. A plurality of engaging protrusions 52C may be provided at intervals. The cross-sectional shape of the ridge shape here is trapezoidal, but it may also be, for example, semicircular, elliptical, triangular, rectangular, etc.

[0070] The surface of the step in the extension portion 52 that is perpendicular to the extension direction of the extension portion 52 is an opposing surface 52B that can come into contact with the tip of the branch base 15 of the wall fixing device 10. That is, as shown in FIG. 1 , when the extension portion 52 is accommodated in the accommodation portion 15B of the branch base 15 of the wall fixing device 10, the opposing surface 52B of the extension portion 52 comes into contact with the tip of the branch base 15 of the wall fixing device 10.

[0071] When the extension portion 52 of the wall mounting member fixing device 50 is accommodated and positioned in the accommodation portion 15B of the branch base 15 of the wall fixing device 10, the inner edge of the first linear portion A 51A and the outer edge of the extension portion 52, a part of the inner edge of the second linear portion C 51C located on the first linear portion A 51A side, and a part of the inner edge of the second linear portion D 51D located on the first linear portion A 51A side face the branched wall fixing portion 13 of the wall fixing device 10 so as to cover the periphery of the branched wall fixing portion 13.

[0072] Therefore, the wall mounting member 100, to whose back surface the wall mounting member fixture 50 is fixed, is effectively prevented from moving in its width direction (lateral direction, horizontal direction). Furthermore, the wall mounting member fixture 50 eliminates the need to provide a hole having the same outer shape as the outer shape of the wall fixture 10 on the back surface (wall surface side) of the wall mounting member 100.

[0073] The outer surfaces of both end portions of the first linear portion B 51B of the wall-mounting-component fastener 50, which are located on the second linear portion C 51C side and the second linear portion D 51D side, are located farther from the first linear portion A 51A than the outer surface of the central portion 51E that can abut against the protrusions 14 of the wall fastener 10. That is, the wall-mounting-component fastener 50 has, in the first linear portion B 51B, the central portion 51E that is approximately parallel to the first linear portion A 51A and located approximately in the center, and outer inclined portions 51G located on both ends (outside) of the central portion 51E.

[0074] Therefore, when the wall mounting member 100 is mounted on a wall, the outer inclined portions 51G located at both ends of the first linear portion B 51B of the wall mounting member fixing device 50 are located lower than the outer surface of the central portion 51E that can abut against the convex portion 14 of the wall fixing device 10. Therefore, the wall fixing device 10 arranged inside the wall mounting member fixing device 50 more restricts the lateral (horizontal) movement of the wall mounting member fixing device 50 (wall mounting member 100), and even when a lateral (horizontal) dynamic load is applied to the wall mounting member 100, rattling or the like does not occur in the wall mounting member 100.

[0075] When the wall-mounting component fixing device 50 is viewed in the direction of the arrows at the AA cross section in FIG. 15, it appears as shown in FIG. 16; when the wall-mounting component fixing device 50 is viewed in the direction of the arrows at the BB cross section in FIG. 15, it appears as shown in FIG. 17; and when the wall-mounting component fixing device 50 is viewed in the direction of the arrows at the CC cross section in FIG. 15, it appears as shown in FIG. 18.

[0076] As shown in FIGS. 16 and 17, the central portion 51E of the first linear portion B 51B of the wall installation component fastener 50 is formed to be thinner than the outer inclined portions 51G located at both ends.

[0077] Therefore, when the extension portion 52 of the wall mounting member fixing device 50 is accommodated in the accommodation portion 15B of the branch base 15 of the wall fixing device 10, as shown in Figures 1 and 2, the central portion 51E of the first linear portion B 51B of the wall mounting member fixing device 50 is arranged in a state overlapping with the base 11 of the wall fixing device 10.

[0078] Next, an example of installation of the wall installation set on a wall using the wall installation tool 1, that is, an example of installation of the wall installation member 100 on a wall using the wall installation tool 1, will be described with reference to FIGS. FIG. 19 is a schematic, partially sectional view illustrating a state in which a wall installation member 100 (catwalk shelf) is installed on a wall using a wall installation tool 1 according to one example of the present invention; FIG. 20 is a schematic, partially sectional view illustrating a state in which the wall installation member 100 (catwalk shelf) is not shown in FIG. 19; and FIG. 21 is a partially enlarged, partially sectional view illustrating an engagement state between the wall fixing device 10 and the wall installation member fixing device 50 in FIG. 19.

[0079] As shown in Figures 19 to 21, the wall mounting member 100 (catwalk shelf material) is installed on a wall in a state in which the wall mounting member fixing device 50 is fixed with a plurality of screws 21 to the back surface of the back material 101 that abuts against the wall, and the wall fixing device 10 is fixed to the wall by inserting rivets (push pins) 20 into rivet holes 13E provided in three locations on each of the two branched wall fixing portions 13, rivet hole 12F provided near the center of the wide portion 12 of the wall fixing device 10, and rivet hole 11C provided on the end side (lower side) of the base 11 of the wall fixing device 10.

[0080] At this time, the extension portion 52 of the wall mounting member fixture 50 is housed in the branch base 15 of the wall fixture 10, and a clicking sensation occurs when the engagement protrusion 52C at the tip of the extension portion 52 engages with the engagement protrusion 15A of the branch base 15 of the wall fixture 10. This allows the installer of the wall mounting member 100 to easily understand that installation is complete.

[0081] At this time, the extension portion 52 of the wall mounting member fixing device 50 comes into contact with the branch base 15 (the separation prevention portion) of the wall fixing device 10, and the outer edge of the central portion 51E of the first linear portion B 51B of the wall mounting member fixing device 50 comes into contact with the load receiving surface 14B (the fall prevention portion) of the convex portion 14 of the wall fixing device 10. Because the branch base 15 functioning as the separation prevention means and the convex portion 14 (load receiving surface 14B) functioning as the fall prevention means are located in different positions, the function of preventing the wall mounting member 100 from separating from the wall and the function of preventing it from falling from the wall can be functionally separated, and even if a large force is applied to the wall mounting member 100, the wall fixing member 10 is less likely to break, and the wall mounting member 100 can be stably and reliably installed on the wall.

[0082] Furthermore, the load-receiving surface 14B of the protrusion 14, to which the load from the wall mounting member 100 is directly applied from the wall mounting member fixing device 50, has a rivet (push pin) 20 inserted downward into the wall directly below it, so that even when a dynamic load is applied to the wall mounting member 100, the wall mounting member 100 can be firmly and stably held on the wall without slippage or the like.

[0083] Furthermore, even when a dynamic load is applied laterally (horizontally) to the wall mounting member 100, the wall mounting member fixing device 50, which is the square frame-shaped member 51, covers the periphery of the wall fixing device 10, so even if the wall mounting member fixing device 50 attempts to move laterally (horizontally), the movement is restricted by the wall fixing device 10, effectively suppressing or preventing rattling, etc. In other words, when the extension portion 52 of the wall mounting member fixing device 50 is accommodated in the accommodation portion 15B of the branch base 15 of the wall fixing device 10, the inner edge of the first linear portion A 51A and the outer edge of the extension portion 52, a part of the inner edge of the second linear portion C 51C located on the first linear portion A 51A side, and a part of the inner edge of the second linear portion D 51D located on the first linear portion A 51A side face the branched wall fixing portion 13 of the wall fixing device 10 so as to cover the periphery of the branched wall fixing portion 13. Therefore, the wall mounting member 100, to whose back surface the wall mounting member fixing device 50 is fixed, is effectively prevented from moving in the width direction (lateral direction, horizontal direction) by the wall fixing device 10. Furthermore, the wall mounting member fixing device 50 eliminates the need to provide a hole having the same outer shape as the outer shape of the wall fixing device 10 on the back surface (wall surface side) of the wall mounting member 100.

[0084] There are no particular limitations on the method for installing the wall mounting tool 1 or the wall mounting set including it, and any suitable method can be selected depending on the purpose, but for example, it can be performed as follows: First, the branched wall fixing portion 13 of the wall fixing device 10 is oriented upward, and rivets (push pins) 20 are inserted into rivet holes 11C, 12F, and 13E to fix the wall fixing device 10 to the wall. Then, the first linear portion A 51A of the wall mounting member fixing device 50 is positioned upward and laterally (horizontally), and screws 21 are threaded into screw holes 103 in recesses 102 of the back material 101 of the wall mounting member 100 to fix the wall mounting member fixing device 50 to the back surface of the wall mounting member 100.

[0085] The rivet (push pin) 20 shown in Fig. 22 can be inserted into the rivet holes 11C, 12F, and 13E using a removal tool 90 shown in Fig. 23. That is, as shown in Fig. 24, the rivet (push pin) 20 can be easily inserted into the wall by pressing the rivet head 20a of the rivet (push pin) 20 with the rivet pressing portion 90a of the removal tool 90. To remove the rivet (push pin) 20 that has been inserted into the wall, as shown in Fig. 25A, the bifurcated rivet extraction portion 90b of the removal tool 90 is inserted under the rivet head 20a of the rivet (push pin) 20, and as shown in Fig. 25B, the removal tool 90 is moved in the direction of the arrow using the rivet extraction portion 90b as a fulcrum, and as shown in Fig. 25C, the rivet (push pin) 20 can be easily removed from the wall by the principle of leverage. This installation tool 90 can be included in the wall installation tool or wall installation set of the present invention.

[0086] Next, the back surface of the back material 101 of the wall mounting member 100 (the wall mounting member fixing device 50 fixed to the back material 101) is abutted against the wall at a position above the branched wall fixing portion 13 of the wall fixing device 10 fixed to the wall, specifically at the position shown in Figure 2.

[0087] At this time, the wide portion 12 and the branched wall fixing portion 13 of the wall fixing device 10 are positioned inside the wall mounting member fixing device 50, which is a square frame-shaped member 51, and the first linear portion B 51B of the wall mounting member fixing device 50 is positioned on the base 11 of the wall fixing device 10. The inner edge of the first linear portion A 51A and the outer edge of the extended portion 52, a part of the inner edge of the second linear portion C 51C located on the first linear portion A 51A side, and a part of the inner edge of the second linear portion D 51D located on the first linear portion A 51A side face the branched wall fixing portion 13 of the wall fixing device 10 so as to cover the periphery of the branched wall fixing portion 13.

[0088] When the first linear portion B 51B of the wall mounting member fixing device 50 is positioned on the wide portion 12 of the wall fixing device 10, the wall mounting member 100 moves away from the wall. However, when the first linear portion B 51B is positioned on the base portion 11, which is thinner than the wide portion 12, the wall mounting member 100 can be abutted against the wall without any gaps. Therefore, the installer can understand that the wall mounting member 100 has been positioned with no gaps between it and the wall, as shown in Figure 2.

[0089] Thereafter, the wall mounting member 100 (wall mounting member fixture 50 fixed to the backing material 101) is slid downward. At this time, the central portion 51E of the first linear portion B 51B of the wall mounting member fixture 50 slides and moves on the base 11 of the wall fixture 10, and the outer edge of the central portion 51E comes into contact with the load-receiving surface 14B of the protrusion 14 of the wall fixture 10. In addition, the extension portion 52 of the wall mounting member fixture 50 is housed in the branch base 15 of the wall fixture 10, and the engaging protrusion 52C at the tip of the extension portion 52 engages with the engaging protrusion 15A of the branch base 15 of the wall fixture 10, producing a clicking sensation. In addition, the tip 13B of the branched wall fixing portion 13 of the wall fixing device 10 faces the inner edge of the first straight portion A 51A of the wall installation member fixing device 50, the opposing surface 52B of the extension portion 52 faces the tip of the branch base 15 of the wall fixing device 10, and the load-receiving surface 14B of the convex portion 14 of the wall fixing device 10 abuts against the outer edge of the central portion 51E of the first straight portion B 51B of the wall installation member fixing device 50.

[0090] As a result, the wall-mounting member 100 is mounted on the wall. The wall fixing device 10 can be fixed to the wall at any time, but can also be fixed to the wall as follows: After the wall mounting member fixing device 50 is fixed to the back surface of the wall mounting member 100 in advance, a rivet (push pin) 20 is inserted into a rivet hole, for example, rivet hole 12F, of the wall fixing device 10, and the extension portion 52 of the wall mounting member fixing device 50 is inserted into the branch base portion 15 of the wall fixing device 10, so that the wall mounting member fixing device 50 and the wall fixing device 10 are temporarily integrated. When this wall mounting member 100 is pressed against a predetermined wall surface, the rivet (push pin) 20 inserted into rivet hole 12F of the wall fixing device 10 is pressed by the back material 101 of the wall mounting member 100 and penetrates the wall. Thereafter, when the wall mounting member fixing device 50 (wall mounting member 100) is removed from the wall fixing device 10, the wall mounting member 10 remains on the wall, temporarily fixed by the rivet (push pin) 20 through the rivet hole 12F. Then, after the wall mounting member 10 has been firmly fixed with the rivet (push pin) 20, the wall mounting member 100 can be installed on the wall by engaging the wall mounting member fixing device 50 with the wall mounting member 10.

[0091] In this way, the wall fixing device 10 in the wall installation tool 1 is fixed to the wall by abutting the wall installation member 100 against the wall with the branched wall fixing portion 13 of the wall fixing device 10 against the wall installation member fixing device 50 fixed to the back surface of the wall installation member 100 in advance. This eliminates the need to position the wall fixing device 10 in advance and fix it to the wall, and is convenient because the wall fixing device 10 can be fixed to the wall as soon as the wall installation member 100 is abutted against the wall.
