  By the way, when installing a braille tile on a hollow floor material such as a deck material, for example, an adhesive is applied to the back surface of the rod body and the side of the mounting leg, and the mounting leg is inserted into the hole formed in the floor material Then attach the braille to the floor. However, in the conventional Braille chopsticks, since the adhesive before curing sometimes falls off from the side of the mounting leg, sufficient adhesion may not be obtained even when the adhesive cures. Therefore, the conventional braille bowl may be detached from the walking surface (mounting surface) even if the time has not passed so much from the installation.

  Then, an object of this invention is to provide the braille wedge which can suppress remove | deviating from a mounting surface, and its construction method.

  In order to achieve the above-mentioned object, the braille cage according to the present invention is a braille bowl having a bowl body and a leg portion provided to extend downward from the bowl body, the leg portion being provided on the outer peripheral surface A first portion including a threaded portion on which a screw thread is formed, and a convex portion which protrudes radially outward of the leg portion relative to the first portion below the first portion and which is continuous in the circumferential direction of the leg portion A bracing member having a second portion for forming a bracing rod, the braille braille comprising the braille main body, and a bracing leg portion extending from the braille main body and having a thread formed on an outer peripheral face; A screw groove is formed in the nut, and the rod member is screwed with the nut member, and the rod screw is formed with a screw thread on the outer peripheral surface, and the rod screw is the screw from the side opposite to the screw leg. It screw-fits to a nut member, and the said nut member is characterized by connecting the said heel leg part and the said rod screw.

  According to such a configuration, when using the adhesive and inserting and attaching the leg of the braille into the hole formed in the mounting surface, the adhesive is entangled in the thread of the first portion, and the second portion Since it accumulates on the top, it is possible to prevent the adhesive from falling down. Thus, after the adhesive is cured, the braille is firmly attached to the mounting surface, so that the braille can be prevented from coming off the mounting surface. In addition, by screwing the hook leg portion of the hook main body to the nut member, the second portion can be formed by the nut member, and the first portion can be formed by the portion exposed from the nut member of the hook leg portion. it can. That is, it is possible to easily form a braille having legs having the first part and the second part. Moreover, the length of a leg part can be easily lengthened by connecting a heel leg part and a rod screw with a nut member. In addition, since the bonding area can be increased when the braille is attached to the mounting surface by using an adhesive because the length of the leg is long, the braille can be further prevented from coming off the mounting surface. . Also, by changing the length of the bar screw, the length of the leg can be easily changed. In other words, the leg length can be easily adjusted.

  Further, in order to achieve the above-mentioned object, the braille cage according to the present invention is a braille bowl having a bowl body and a leg portion provided to extend downward from the bowl body, and the leg portion has an outer periphery A first portion including a screw portion having a thread formed on a surface, and radially outward of the leg portion below the first portion with respect to the first portion and is continuous in a circumferential direction of the leg portion And a second portion forming a convex portion, and a difference between the maximum diameter of the second portion and the outer diameter of the screw portion is 1 to 3 mm.

  According to such a configuration, when using the adhesive and inserting and attaching the leg of the braille into the hole formed in the mounting surface, the adhesive is entangled in the thread of the first portion, and the second portion Since it accumulates on the top, it is possible to prevent the adhesive from falling down. Thus, after the adhesive is cured, the braille is firmly attached to the mounting surface, so that the braille can be prevented from coming off the mounting surface. In addition, the gap between the first portion and the inner peripheral surface of the hole of the mounting surface can be reduced by not increasing the difference between the maximum diameter of the second portion and the outer diameter of the screw portion. When attaching the rod to the mounting surface, the Braille rod can be more firmly attached to the mounting surface. This makes it possible to further suppress the braille from coming off the mounting surface.

  The above-mentioned braille bowl has a weir member having a weir foot portion extending from the weir body and the weir body and having a thread formed on the outer circumferential surface, and a thread groove is formed on the inner circumferential surface And a nut member in which the part is screwed.

That is, it is possible to easily form a braille having legs having the first part and the second part.

  The above-mentioned braille hammer is provided with a rod screw whose outer peripheral surface is formed with a screw thread, and the rod screw is screwed into the nut member from the side opposite to the hook leg portion, and the nut member is the hook leg It is possible to connect the part and the rod screw.

  According to this, it is possible to easily lengthen the length of the leg portion by connecting the heel leg portion and the rod screw with the nut member. In addition, since the bonding area can be increased when the braille is attached to the mounting surface by using an adhesive because the length of the leg is long, the braille can be further prevented from coming off the mounting surface. . Also, by changing the length of the bar screw, the length of the leg can be easily changed. In other words, the leg length can be easily adjusted.

  In the above-described braille, the outer peripheral surface of the second portion may be configured to be circular.

  According to this, when attaching a bran to a mounting surface, the diameter of the hole formed in a mounting surface can be made small. This makes it possible to reduce the gap between the leg portion and the inner peripheral surface of the hole on the mounting surface, thereby minimizing the amount of adhesive when attaching the braille to the mounting surface using the adhesive. It is possible to suppress the heel from coming off the mounting surface.

  In the above-described braille bowl, the leg portion may have a polygonal hole portion whose depth is smaller than the length of the leg portion on the tip end surface.

  According to this, when the braille is attached to the mounting surface using the adhesive, the adhesive enters the hole of the polygon, and after the adhesive is cured, the adhesive becomes a detent of the braille. It is possible to suppress rotation of the braille after installation. This makes it possible to further suppress the braille from coming off the mounting surface.

Hereinafter, an embodiment of the invention will be described in detail with reference to the drawings as appropriate.
As shown in FIGS. 1 (a) and 1 (b), the braille 1 according to one embodiment has a tub body 11 and a leg 40 provided to extend downward from the tub body 11. . The braille 1 according to the present embodiment includes a wedge member 10, a nut member 20, and a rod screw 30 as shown in FIG. 1 (c).

The wedge member 10 has a wedge body 11 and a wedge leg 12 constituting a leg 40.
As shown in FIG. 2, the crucible main body 11 is a part which protrudes from the attachment surface S to which the braille 1 is attached, and is formed in a flat truncated cone shape.

  The heel leg portion 12 is a portion extending downward from the center of the lower surface 11B of the heel main body 11, and is formed in a substantially cylindrical shape. The ridge 12 is formed with a thread 12A on the outer peripheral surface (side surface). The length of the heel leg 12 may be, for example, 15 to 23 mm, for example, 15 mm. Further, the outer diameter of the heel leg 12 may be, for example, 5.5 to 10 mm, for example, 6 mm.

  The wedge member 10 can be formed of an appropriate material such as metal or resin. The heel main body 11 and the heel leg 12 may be formed of the same material, or may be formed of different materials.

  The nut member 20 is a member which constitutes the leg portion 40 together with the heel leg portion 12, and is formed in a cylindrical shape which vertically penetrates. The screw groove 21 is formed in the inner peripheral surface of the nut member 20, and the hook leg 12 of the hook member 10 is screwed. The height of the nut member 20 can be, for example, 10 to 12 mm. Moreover, the outer diameter of the nut member 20 can be set to, for example, 6 to 12 mm, for example, 7.5 mm. Similar to the wedge member 10, the nut member 20 can be formed of an appropriate material such as metal or resin.

  The rod screw 30 is a member that constitutes the leg 40 together with the heel leg 12 and the nut member 20, and is formed in a substantially cylindrical shape. The thread 31 is formed on the outer peripheral surface (side surface) of the rod screw 30. The rod screw 30 is screwed into the nut member 20 from the side opposite to the hook leg 12 of the hook member 10. Thereby, the nut member 20 connects the wedge member 10 and the rod screw 30. The length of the rod screw 30 can be, for example, 15 to 45 mm. The outer diameter of the rod screw 30 may be, for example, 5.5 to 10 mm, for example, 6 mm. Similar to the wedge member 10 and the nut member 20, the rod screw 30 can be formed of an appropriate material such as metal or resin.

The leg portion 40 is constituted by the hook leg portion 12 of the hook member 10, the nut member 20 and the rod screw 30, and has a first portion 41, a second portion 42 and a third portion 43.
The first portion 41 is constituted by the heel leg 12 of the heel member 10. Specifically, the first portion 41 is constituted by a portion of the heel leg 12 exposed from the nut member 20, more specifically, a portion above the nut member 20. For this reason, the first portion 41 includes a screw portion 41A having a screw thread 12A formed on the outer peripheral surface thereof. In the present embodiment, the entire outer peripheral surface of the first portion 41 is a screw portion 41A.

  The second portion 42 is a portion that protrudes radially outward of the leg portion 40 below the first portion 41 and is formed by the nut member 20. In the present embodiment, since the nut member 20 is cylindrical, the second portion 42 forms a convex portion continuous in the circumferential direction of the leg portion 40. Moreover, the outer peripheral surface of the 2nd part 42 is circular because the nut member 20 is cylindrical shape. The difference between the maximum diameter of the second portion 42 and the outer diameter of the threaded portion 41A, specifically, the difference between the outer diameter of the nut member 20 and the outer diameter of the heel leg 12, is preferably not too large, for example It is desirable that it is 1 to 3 mm. To explain further, it is desirable that the maximum projecting amount of the second portion 42 with respect to the first portion 41 is 0.5 to 1.5 mm.

  The third portion 43 is constituted by a rod screw 30. Specifically, the third portion 43 is constituted by a portion of the rod screw 30 exposed from the nut member 20. For this reason, in the third portion 43, a thread 31 is formed on the entire outer peripheral surface.

  Further, the leg portion 40 (specifically, the rod screw 30) has a polygonal hole portion 44 in the tip end surface 40E (lower end surface). The hole 44 is formed as a bottomed hole that is recessed upward from the tip end surface 40E of the leg 40. The holes 44 are formed in a regular hexagon when viewed from the direction orthogonal to the tip end surface 40E (see FIG. 1 (b)). The depth D44 of the hole 44 may be smaller than the length L40 of the leg 40, and may be, for example, 2 to 6 mm. Further, the size of the hole 44, for example, the diameter of the circumscribed circle of the hole 44 (in this embodiment, the length of the diagonal connecting the facing apexes of the regular hexagon) is 2.5 to 6 mm, for example. And so on. The length L40 of the leg 40 can be, for example, 30 to 60 mm.

  The braille 1 is assembled by screwing the hook leg 12 of the hook member 10 into the nut member 20 and screwing the rod screw 30 into the nut member 20 from the side opposite to the hook leg 12. Under the present circumstances, an adhesive agent is applied and fixed to at least one of the part screwed to the nut member 20 of the heel leg 12 and the inner peripheral surface of the nut member 20 so that the wedge member 10 and the nut member 20 do not separate. It is also good. Similarly, an adhesive may be applied and fixed to at least one of the portion screwed to the nut member 20 of the rod screw 30 and the inner peripheral surface of the nut member 20 so that the nut member 20 and the rod screw 30 do not come off. Good.

  Next, the construction method of the braille 1 according to the embodiment, specifically, the method of attaching the braille 1 to the mounting surface S will be described.

First, an example of a method of attaching the braille 1 to a hollow floor material 50 as shown in FIG. 3 used on a deck such as a wood deck, a veranda, a balcony, a promenade and the like will be described.
The floor material 50 mainly includes an upper plate 51, a lower plate 52, and a plurality of connecting portions 53. The upper plate 51 and the lower plate 52 are disposed at predetermined intervals in the vertical direction, and the connecting portion 53 is provided so as to extend in the vertical direction and connect the upper plate 51 and the lower plate 52. The floor material 50 is formed of, for example, wood (natural wood), resin, a composite of wood and resin, or the like.

  When attaching the braille 1 to such a floor material 50, first, as shown in FIG. 4, a hole forming step of forming the holes 51H and 52H in the floor material 50 is performed. Specifically, in the hole forming step, a first through hole 51H (through hole) for inserting the leg portion 40 of the braille 1 into the upper plate 51 (mounting surface S) using a drill T1 or the like for woodworking Of the upper surface 52A of the lower plate 52, and a second hole 52H (concave portion) which does not penetrate through the portion facing the first hole 51H. The diameter of the holes 51H and 52H can be slightly larger than the outer diameter of the leg 40 (specifically, the nut member 20), for example, about 0.5 to 1 mm larger. Also, the depth of the second hole 52H can be, for example, about half the thickness of the lower plate 52.

  Next, as shown to FIG. 5 (a), (b), the application process which apply | coats the adhesive agent 60 to the flooring 50 and the braille 1 is performed. Specifically, in the application step, as shown in FIG. 5A, the nozzle T2 for injecting the adhesive is inserted from the first hole 51H of the upper plate 51, and the adhesive 60 is injected to form the lower plate 52. An adhesive reservoir 60P is provided in a portion of the upper surface 52A opposite to the first hole 51H, and more specifically, in the second hole 52H and the periphery thereof.

  Further, as shown in FIG. 5 (b), the adhesive 60 is applied to the lower surface 11 B of the crucible main body 11 and the first portion 41 of the leg portion 40 of the braille 1. Further, the adhesive 60 is applied to the tip 40A of the leg 40 of the braille 1. When the adhesive 60 is applied to the tip 40A, the adhesive 60 is applied to fill not only the outer peripheral surface of the tip 40A and the tip surface 40E but also the inside of the hole 44 formed in the tip surface 40E. .

  In addition, although an example of the application | coating process was demonstrated here, the order which apply | coats the adhesive agent 60 is arbitrary.

  Although the adhesive agent 60 can be suitably selected according to the material of the braille 1 and the flooring 50 (attachment surface S), a two-component epoxy adhesive etc. can be used as an example.

  Next, as shown to Fig.6 (a), the attachment process of attaching braille 1 to the floor material 50 is performed. Specifically, in the attachment step, the leg portion 40 of the braille 1 is inserted into the first hole 51H, whereby the tip 40A of the leg portion 40 is placed on the adhesive reservoir 60P on the lower plate 52 (see FIG. 5A). And the lower surface 11B of the main body 11 is attached to the surface 50A of the floor material 50.

  Then, after the mounting process, a rotation process is performed in which the adhesive 60 applied to the braille 1 and the adhesive 60 applied to the floor material 50 are integrated. Specifically, in the rotation step, the braille 鋲 1 is applied once or more (360 ° or more), for example, two to three times, by gripping the eyelid main body 11 or the like, and applied to the tip 40A of the leg 40 The adhesive 60 and the adhesive 60 applied to the lower plate 52 are mixed and integrated. Further, by rotating the braille 1, the adhesive 60 applied to the first portion 41 of the leg portion 40 can be attached over the entire circumference of the inner peripheral surface of the first hole 51 H of the upper plate 51.

  And if adhesive agent 60 hardens, attachment (construction) to floor material 50 (attachment side S) of braille 1 is completed.

  Here, as shown in FIG. 6 (b), the conventional braille 9 is a hole in which the adhesive 60 is applied to the lower surface of the crucible main body 91 and the side of the leg 94 and the leg 94 is formed in the floor material 50. In the case of being inserted and attached to 51 H, the adhesive 60 before curing may fall down on the upper surface 52 A of the lower plate 52 from the side surface of the leg portion 94. When the adhesive 60 falls down and the amount decreases, sufficient adhesive strength can not be obtained even if the adhesive 60 cures, so the conventional braille 9 has a long time since the installation on the mounting surface S Even if it did not, it might come off from the mounting surface S.

  On the other hand, as shown in FIG. 6A, when the braille 1 of the present embodiment uses the adhesive 60 and inserts the leg portion 40 of the braille 1 into the hole 51H formed in the mounting surface S, The adhesive 60 tangles with the thread 12 A of the first portion 41 and accumulates on the protruding second portion 42, so that the adhesive 60 can be prevented from falling on the lower plate 52. Thus, after the adhesive 60 is cured, the braille 1 is firmly attached to the mounting surface S, so that the braille 1 can be prevented from coming off the mounting surface S.

  In addition, since the protruding second portion 42 is caught after the adhesive 60 is cured, detachment of the braille 1 from the mounting surface S can be further suppressed.

  Further, since the braille 1 is configured to include the wedge member 10 and the nut member 20, the second part 42 can be formed by the nut member 20 by screwing the wedge leg portion 12 of the wedge member 10 into the nut member 20. The first portion 41 can be formed by the portion exposed from the nut member 20 of the heel leg 12. That is, according to the present embodiment, the braille 1 having the leg portion 40 having the first portion 41 and the protruding second portion 42 can be easily formed.

  In addition, since the braille cage 1 is configured to include the wedge member 10 and the nut member 20, the relative position between the wedge main body 11 and the nut member 20 can be changed. The distance to the top surface of the two portions 42 can be adjusted. Thus, for example, the upper surface of the second portion 42 can be disposed at an appropriate position in accordance with the thickness of the upper plate 51 of the floor material 50, so that the adhesive 60 before curing is effectively reduced. Can be suppressed.

  In addition, since the outer peripheral surface of the second portion 42 (nut member 20) is circular, when attaching the braille 1 to the mounting surface S as compared with, for example, a hexagonal or quadrilateral, the mounting surface S The diameter of the hole 51H to be formed can be reduced. This makes it possible to reduce the gap between the leg 40 and the inner peripheral surface of the hole 51H, and therefore, when attaching the braille 1 to the mounting surface S using the adhesive 60, the amount of the adhesive 60 is minimized. At the same time, it is possible to suppress the braille 1 from coming off the mounting surface S.

  In addition, the difference between the maximum diameter of the second portion 42 and the outer diameter of the screw portion 41A (the first portion 41) is not increased to, for example, 1 to 3 mm, so that the first portion 41 and the inner circumferential surface of the hole 51H Since the gap between them can be made small, when attaching the braille 1 to the mounting surface S using the adhesive 60, the braille 1 can be more firmly attached to the mounting surface S. Thereby, it is possible to further suppress the braille 1 from coming off the mounting surface S.

  In addition, when the braille 1 is attached to the mounting surface S using the adhesive 60, the adhesive 60 enters the hole portion 44 of the regular hexagon, so that the adhesive 60 is cured after the adhesive 60 is cured. It becomes a detent. Specifically, the adhesive 60 applied in the holes 44 of the regular hexagon is connected to the adhesive 60 applied to the lower plate 52 and cured, so that the cured adhesive 60 stops the rotation of the braille 1 and Become. As a result, since rotation of the braille 1 after attachment to the mounting surface S can be suppressed, the braille 1 can be further suppressed from coming off the mounting surface S (floor member 50).

  In addition, when the braille 1 is attached to the floor material 50 having the upper plate 51 and the lower plate 52 which are disposed at predetermined intervals in the vertical direction, the base end portion of the leg portion 40 (first Since the portion 41) is fixed to the upper plate 51 of the floor material 50 and the tip 40A of the leg 40 is fixed to the lower plate 52 of the floor material 50, the braille 1 can be firmly attached to the floor material 50 .

  In particular, in the construction method described above, the second hole 52H is formed in a portion facing the first hole 51H of the upper surface 52A of the lower plate 52, and the adhesive 60 is applied to the inside of the second hole 52H and its peripheral portion Since the bonding area between the adhesive 60 and the lower plate 52 can be increased, the braille 1 can be attached more firmly to the floor material 50.

  Moreover, in the construction method mentioned above, after the braille 1 is inserted into and attached to the floor material 50, the braille 1 is rotated one or more times, so the adhesive applied to the tip 40A of the leg 40 of the braille 1 Since the adhesive 60 of the adhesive reservoir 60P on the lower plate 52 is mixed and integrated, the braille 1 can be firmly attached to the floor material 50.

  In addition, in order to prevent the outflow of the adhesive 60 applied to the lower plate 52, it is desirable that the holes 52H do not penetrate. In other words, it is desirable that the leg 40 of the braille 1 has a length such that the tip 40A does not protrude from the back surface 50B of the floor material 50. Further, in the present embodiment, the leg 40 is formed in such a length that the tip 40A enters into the hole 52H of the lower plate 52 when the braille 1 is attached to the floor material 50, but the tip is The length 40A may not enter the hole 52H.

Next, an example of a method of attaching the braille 1 on a solid floor material made of solid wood or the like instead of the hollow floor material 50 or on a sidewalk such as asphalt pavement surface instead of the floor material will be described.
In this case, first, a hole forming process is performed. Specifically, in the hole forming step, as shown in FIG. 7A using a drill or the like (not shown), a hole 55H with a bottom for inserting the leg portion 40 of the braille 1 into the mounting surface S (recessed portion Form).

  Next, an application process is performed. Specifically, in the application step, a nozzle for injecting an adhesive (not shown) is inserted into the hole 55H formed in the mounting surface S, and the adhesive 60 is injected to form an adhesive reservoir. Further, the adhesive 60 is applied to the lower surface 11 B of the crucible main body 11 and the first portion 41 of the leg 40 of the braille 1, and the adhesive 60 is applied in the hole 44 of the leg 40. The application process here may be performed in the order of applying the adhesive 60 to the braille 1 and then injecting the adhesive 60 into the hole 55H. Moreover, although the adhesive agent 60 is apply | coated to the lower surface 11B of the crucible main body 11 here, it is not necessary to apply.

  Next, the mounting process is performed. Specifically, in the attachment step, the leg portion 40 of the braille 1 is inserted into the hole 55H, and the tip end 40A of the leg 40 is attached to the adhesive 60 (adhesive reservoir) injected into the hole 55H. Attach the lower surface 11 B of 11 to the mounting surface S. In addition, after the attachment process, you may perform the rotation process which rotates the braille 1 more than once as needed. Then, when the adhesive 60 is cured, the attachment (construction) of the braille 1 to the mounting surface S is completed.

  In the braille 1, since the leg 40 is formed by connecting the rod 12 of the rod 10 and the rod screw 30 with the nut member 20, the length of the leg 40 can be easily increased. it can. Further, the length of the leg 40 is longer than that of the leg 94 of the conventional braille 9 shown in FIG. 7B, so that the braille 1 is attached to the mounting surface S using the adhesive 60. Sometimes, the bonding area can be increased. Thereby, since the braille 1 can be firmly attached to the mounting surface S, it is possible to further suppress the braille 1 from coming off the mounting surface S.

  In particular, in the braille 1, since the first portion 41 includes the screw portion 41A in which the screw thread 12A is formed on the outer peripheral surface, and the screw thread 31 is formed on the outer peripheral surface of the third portion 43 The bonding area can be further increased as compared with the case where no is formed. Thereby, the braille 1 can be attached more firmly to the mounting surface S. In addition, since the screw threads 12A and 31 become stuck, it is possible to further suppress the braille 1 from coming off the mounting surface S.

Moreover, as shown to Fig.8 (a), although the sidewalk 55 in which the braille 1 is set may be comprised from a several layer, the braille 1 is remove | deviated from the attachment surface S also in this case. It is difficult.
For example, when the upper layer 55A is an asphalt layer, the asphalt layer may become hot and softened by being exposed to direct sunlight in summer. The conventional braille 9 shown in FIG. 8 (b) may be sunk by the softening of the asphalt layer or the adhesive 60 may be softened and removed. On the other hand, since the lower end portion of the leg portion 40 including the tip end portion 40A of the leg portion 40 reaches the lower layer 55B and is firmly adhered and fixed to the lower layer 55B, it sinks even if the upper layer 55A (asphalt layer) softens. It is difficult to get stuck or dislodged.

  Also, if the upper layer 55A is a block such as an interlocking block placed on the lower layer 55B, the block may move. In the conventional braille 9 shown in FIG. 8 (b), since the adhesive strength is weak due to the short leg 94, there has been a case where the one placed particularly at the boundary of the block is detached. On the other hand, since the lower end portion of the leg portion 40 reaches the lower layer 55B and is firmly adhered and fixed to the lower layer 55B, the braille 1 is difficult to remove even if the upper layer 55A (block) moves.

  When the upper layer 55A is a rubber tile installed in the lower layer 55B made of a concrete layer or the like, the rubber tile bends or the upper portion moves. In the conventional braille 9 shown in FIG. 8B, since the leg 94 is short and not firmly fixed to the lower layer 55B, the rubber tile may be detached by bending or movement. On the other hand, since the lower end portion of the leg portion 40 reaches the lower layer 55B and is firmly adhered and fixed to the lower layer 55B, the braille 1 is hard to be detached even if the upper layer 55A (rubber tile) is bent or moved. It has become.

  In addition, when the braille 1 is attached on a solid floor material or a sidewalk, the adhesive 60 is not injected into the hole 55H in the coating step, and the lower surface 11B of the braille main body 11 of the braille 1 and the first The adhesive 60 may be applied to the side of the leg 40 including the portion 41, and the leg 40 may be inserted into and attached to the hole 55H.

  In this case, for example, as shown in FIGS. 9A and 9B, if the hole 55H formed in the mounting surface S is too deep relative to the length of the legs 40 and 94, as shown in FIG. In the conventional braille 9 shown in the drawings, the adhesive 60 before curing falls off from the side surface of the leg portion 94, so that the adhesive strength may be insufficient and it may be detached from the mounting surface S. On the other hand, in the braille 鋲 1 shown in FIG. 9A, the adhesive 60 is entangled with the screw thread 12A of the first portion 41 and accumulated on the second part 42, so it is difficult to fall off. Can be firmly attached to the mounting surface S, and it is possible to suppress detachment from the mounting surface S. In other words, the conventional braille 9 may be easily detached from the mounting surface S after installation unless the depth of the hole 55H is strictly controlled, but the braille 1 has a difference in the degree of skill of the builder, etc. Thus, even if the depth of the hole 55H can not be strictly controlled, it is possible to suppress detachment from the mounting surface S.

  Moreover, as shown in FIGS. 10 (a) to (c), the Braille rod 1 can easily change the length of the leg 40 by changing the length of the rod screw 30 (30A, 30B, 30C) Can. In other words, the braille 1 can adjust the length of the leg 40 easily. As an example, the length of the rod screw 30A may be 20 mm, the length of the rod screw 30B may be 25 mm, and the length of the rod screw 30C may be 30 mm.

  As mentioned above, although embodiment was described, this invention is not limited to the said embodiment. About a specific structure, it can change suitably in the range which does not deviate from the meaning of invention as follows. In the following, the same components as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted, and only differences from the above-described embodiment will be described.

  In the said embodiment, although the braille 1 was comprised from the wedge member 10, the nut member 20, and the rod screw 30, it is not limited to this. For example, the braille 1 may be composed of a wedge member 10 and a nut member 20.

  In this case, for example, as shown in FIGS. 11A and 11B, the length of the heel leg 13 of the heel member 10 may be longer than that of the heel leg 12 of the embodiment. The length of the heel leg 13 may be, for example, 20 to 60 mm. In the braille 1 shown in FIG. 11, the portion of the heel leg 13 above the nut member 20 constitutes the first portion 41, and the portion below the nut member 20 constitutes the third portion 43. There is. Further, the braille 1 shown in FIG. 11 applies an adhesive to at least one of the side surface of the heel leg 13 and the inner peripheral surface of the nut member 20 during use so that the wedge member 10 and the nut member 20 do not come off. It is desirable to fix it.

  Further, as shown in FIG. 12, in the braille 1 configured by the wedge member 10 and the nut member 70, the nut member 70 is not a penetrating cylindrical like the nut member 70 of the embodiment but has It may be cylindrical at the bottom. The screw groove 71 is formed in the inner peripheral surface of the nut member 70, and the hook leg 12 of the hook member 10 is screwed. In the braille 1 shown in FIG. 12, the portion of the heel leg 12 exposed from the nut member 70 constitutes a first portion 41, and the nut member 20 constitutes a second portion 42.

  Moreover, in the said embodiment, although point-like (for warning) Braille で は 1 was illustrated, it is not limited to this, For example, as shown to Fig.13 (a), linear (for guidance) Braille 鋲 8 It may be In more detail, the braille 8 may be configured to have a long and flat quadrangular frustum-like tub body 81 and a leg 40 provided to extend downward from the tub body 81. In the braille 8, a plurality of, for example, three legs 40 are provided. To explain further, as shown in FIG. 13 (b), the braille 8 comprises a wedge member 80 having a wedge body 81 and three wedge legs 12, a nut member 20 and a rod screw 30. According to such a braille 8, as in the case of the braille 1, it is possible to suppress detachment from the mounting surface.

  Moreover, in the said embodiment, although the hole 44 formed in the front end surface 40E of the leg part 40 was a regular hexagon, it is not limited to this. For example, the hole may be a regular pentagon or a square such as a square or a rectangle. The hole may be an equilateral triangle, or may be a star polygon such as a star regular hexagon or a star regular pentagon. In addition, the hole part should just be a polygon, and is not limited to a regular polygon. The braille may have a configuration without a hole.

  Moreover, in the said embodiment, although the outer peripheral surface of the 2nd part 42 of the leg part 40 was circular, it is not limited to this. For example, the outer peripheral surface of the second portion may be a regular hexagon or a square.

  Moreover, in the said embodiment, although the 1st part 41 of the leg part 40 used the whole screw part 41A as the outer peripheral surface, it is not limited to this. For example, the first portion may have a configuration in which only a part of the outer peripheral surface is a threaded portion. In other words, the first portion may have a configuration in which a thread is formed only on a part (for example, the lower end) of the outer peripheral surface.

  Further, in the embodiment, the second portion 42 is formed by the nut member 20 by screwing the nut member 20 into the hook leg portion 12 of the hook member 10, and a portion exposed from the nut member 20 of the hook leg portion 12. Although the braille 1 in which the 1st portion 41 is formed is illustrated by ,, it is not limited to this. For example, the braille hammer may have a configuration in which the first portion and the second portion are formed by cutting a portion to be a leg portion.

  In addition, the present invention may be implemented by arbitrarily combining the elements described in the above-described embodiment and the modification.
