Description

[Technical field]

[0001] The technology of the present disclosure relates to a handrail device. [Background technology]

[0002] Patent Document 1 describes a support device used when attaching a handrail or auxiliary handrail to an interior board material that is stretched over the framework of a building. Specifically, the support device includes an expansion anchor, a spacer, a base, and a mounting screw.

[0003] Then, with the expansion anchor inserted through the installation hole in the plate, the guide string attached to the expansion anchor is passed through the central through hole of the spacer, and the guide string is then inserted through the guide groove in the central through hole of the base to cover the spacer with the base. This allows the position of the guide string to be recognized from the front side of the plate. In other words, because the position of the guide string can be recognized from the front side, the angle of the expansion anchor in the longitudinal direction can be confirmed from the front side, preventing incorrect installation.

[0004] [Patent Document 1] JP 2005-133430 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the technology described in Patent Document 1, it is desirable to fix the expansion anchor to the plate so that it is oriented in a predetermined direction relative to the handrail. However, since the expansion anchor is placed on the back side of the plate, it is difficult to check the orientation of the expansion anchor from the front side. In addition, in the configuration of Patent Document 1, the guide cord of the expansion anchor is located on the front side of the plate, but the guide cord is flexible and its relative position to the expansion anchor changes due to deformation, making it difficult to actually adjust the orientation of the expansion anchor.

[0006] An object of the technology disclosed herein is to obtain a handrail device that allows the orientation of an anchor piece located on the rear surface of a wall member to be confirmed and that allows the orientation of the anchor piece to be adjusted from the front surface side of the wall member. [Means for solving the problem]

[0007] A handrail device of a first aspect includes an anchor piece that is engaged with the back surface of a wall member and has a female thread portion, a mounting member for engaging the anchor piece at a position corresponding to the mounting hole on the back surface of the wall member, a bracket member having a base portion disposed at a position corresponding to the mounting hole on the front surface of the wall member, a handrail member supported by the bracket member, a bolt member that is inserted through an insertion hole in the base portion of the bracket member and the mounting hole in the wall member and is screwed into the female thread portion of the anchor piece, and fastens the wall member and the base portion of the bracket member together with the anchor piece, and a bolt member that is inserted through the insertion hole in the bracket member and the mounting hole in the wall member, The wall member has a bolt member which is screwed into the female threaded portion of the anchor piece on the back side of the wall member and fastens the wall member and the bracket member, and the base portion of the bracket member has a viewing hole which exposes a portion of the mounting member to make it visible from the front side of the wall member, and the mounting member has a flange member which is fitted into the mounting hole on the front side of the wall member and through which the bolt member is inserted, a band member which is connected to the anchor piece and the flange member and which is inserted into the mounting hole of the wall member, and a characteristic portion which is visible through the viewing hole when the anchor piece is engaged at a specific rotational position at a position corresponding to the mounting hole on the back side of the wall member.

[0008] In this handrail device, the bolt member is inserted through the insertion hole in the base part of the bracket member and the mounting hole in the wall member, and is further screwed into the female thread part of the anchor piece engaged with the back surface of the wall member. The bolt member, together with the anchor piece, fastens the wall member and the base part of the bracket member. As a result, the bracket member is fixed to the wall member, and the handrail member supported by the bracket member is attached to the wall member.

[0009] The mounting member has a flange member, a band member, and a characteristic portion. The flange member through which the bolt member is inserted is fitted into the mounting hole on the front surface side of the wall member. The band member is connected to the anchor piece and the flange member, and is inserted into the mounting hole of the wall member. This realizes a structure in which a part of the mounting member is located on the front surface side of the wall member, so that the orientation of the anchor piece can be adjusted by operating the mounting member from the front surface side of the wall member.

[0010] A viewing hole is provided in the base portion of the bracket member. The characteristic portion of the mounting member is visible through the viewing hole when the anchor piece is locked at a specific rotational position at a position corresponding to the mounting hole on the rear surface of the wall member. In other words, when the characteristic portion is visible through the viewing hole, it can be confirmed that the anchor member is locked at the specific rotational position.

[0011] The handrail device of the second aspect is the handrail device of the first aspect, wherein the characteristic portion is a sign portion provided on the flange member.

[0012] By providing a simple structure in which a marking portion is provided on the flange member, a characteristic portion can be provided on the mounting member.

[0013] A third aspect of the handrail device is based on the first aspect, and the characteristic portion is a portion of the band member that protrudes from the flange member toward the surface side of the wall member and reaches the viewing hole.

[0014] By making the characteristic portion a portion of the band member that protrudes from the flange member towards the front surface of the wall member and reaches the viewing hole, the characteristic portion can be provided on the attachment member as a part of the band member.

[0015] The handrail device of a fourth aspect is any one of the first to third aspects, wherein the insertion hole and the viewing hole are separately provided in the base portion of the bracket member.

[0016] Since the insertion hole and the viewing hole are provided separately, the insertion hole can be shaped to suitably insert the bolt member, and the viewing hole can be shaped to suitably view the characteristic portion.

[0017] A handrail device of a fifth aspect is any one of the first to third aspects, wherein the insertion hole and the viewing hole are formed continuously in the base portion of the bracket member.

[0018] Since the insertion hole and the viewing hole are not provided separately but are integrated, the structure can be simplified.

[0019] The handrail device of the sixth aspect is any one of the first to fifth aspects, in which the anchor piece is fixed to the back surface of the wall member with its longitudinal direction being perpendicular to the extension direction of the handrail member when viewed in the normal direction of the back surface of the wall member.

[0020] When the handrail member is subjected to a force having a component perpendicular to its extension direction, it can exert a stronger resistance to this force compared to a configuration in which the longitudinal direction of the anchor piece is parallel to the extension direction of the handrail member. Effect of the Invention

[0021] According to the present invention, the orientation of the anchor piece located on the back surface of the wall member can be confirmed, and the orientation of the anchor piece can be adjusted from the front surface side of the wall member. [Brief description of the drawings]

[0023] Hereinafter, an example of an embodiment of the present application will be described in detail with reference to the drawings.

[0024] First embodiment Fig. 1 and Fig. 2 show a handrail device 1 of a first embodiment as viewed from the side. Fig. 3 partially shows the handrail device 1 attached to a wall member 2. Fig. 4 to Fig. 7 show partially enlarged perspective views of the handrail device 1 in the middle of being attached to the wall member 2.

[0025] The handrail device 1 of the first embodiment is attached to a wall member 2 of a building or the like. The wall member 2 includes a plaster board 21 and a reinforcing plate 22. The plaster board 21 is reinforced by the reinforcing plate 22. In the wall member 2, the front surface (the surface of the plaster board 21) to which the reinforcing plate 22 is not attached is the front surface 2A, and the rear surface (the surface of the reinforcing plate 22) to which the reinforcing plate 22 is attached is the rear surface 2B. Hereinafter, the front surface 2A side of the wall member 2 may be referred to as the front side, and the rear surface 2B side may be referred to as the rear side.

[0026] As shown in Fig. 3, the handrail device 1 has an anchor piece 3, an attachment member 4 (see Figs. 4 and 5), a bracket member 5, a handrail member 6, and a bolt member 7. The attachment member 4 has a band member 41 and a flange member 45. The handrail device 1 is ready for use by fixing the bracket member 5 to the wall member 2 using the anchor piece 3, the attachment member 4 (more specifically, a combination of a part of the band member 41 and the flange member 45), and the bolt member 7, and attaching the handrail member 6 to the pair of fixed bracket members 5.

[0027] The handrail member 6 is formed, for example, in a rod shape. Bracket members 5 are attached to both longitudinal ends of the handrail member 6. The handrail device 1 is supported and fixed to the wall member 2 by the bracket members 5. In this state, the handrail member 6 is disposed apart from and parallel to the surface 2A of the wall member 2. Therefore, it is possible to grip the handrail member 6, for example, by inserting a finger between the surface 2A of the wall member 2 and the handrail member 6.

[0028] 2 and 4, a mounting hole 23 is formed in the wall member 2. The mounting hole 23 penetrates the wall member 2 in the thickness direction.

[0029] As shown in Figures 2, 6 and 7, the bracket member 5 has a fixing portion 51 and a base portion 53. An end of the handrail member 6 is fixed to the fixing portion 51 by a fixing bolt 52 or the like. The base portion 53 is formed in a plate shape that fits along the wall member 2. When the handrail device 1 is attached to the wall member 2, the base portion 53 contacts or faces the surface 2A of the wall member 2. The base portion 53 is disposed at a position on the surface 2A of the wall member 2 that corresponds to the mounting hole 23.

[0030] An insertion hole 54 is formed in approximately the center of the base portion 53 when viewed from the front. With the handrail device 1 attached to the wall member 2, the bolt body 71 of the bolt member 7 is inserted into the insertion hole 54. That is, the bolt body 71 is inserted into the insertion hole 54 of the base portion 53 and the mounting hole 23 of the wall member 2.

[0031] As described below, the anchor piece 3 is engaged with the rear surface 2B of the wall member 2. The bolt body 71 is further screwed into the female thread portion 31 of the anchor piece 3. A nut member 73 is screwed into the bolt body 71 from the front side, whereby the wall member 2 and the base portion 53 of the bracket member 5 are fastened between the anchor piece 3 and the nut member 73.

[0032] In the base portion 53, visual holes 55 are formed above and below the insertion hole 54 in a front view. The visual holes 55 are formed at positions where the marker portion 8 can be visually recognized from the front side, i.e., the front surface 2A side, when the marker portion 8 is in a predetermined position in the circumferential direction of the mounting hole 23. In the example shown in Figs. 6 to 8, two visual holes 55 are formed at positions with a central angle of 180 degrees with respect to the insertion hole 54. In particular, the position and size of the visual holes 55 are determined so that the marker portion 8 appears in approximately half of the inner area of ​​the visual holes 55 when the anchor piece 3 is in a specific rotational position. In the first embodiment, the visual holes 55 are provided separately from the insertion hole 54.

[0033] A cover 57 is further attached to the bracket member 5 to improve its appearance. Note that Fig. 6 shows the bracket member 5 with the cover 57 removed.

[0034] As shown in Fig. 3, when the handrail device 1 is attached to the wall member 2, the anchor piece 3 is engaged with the back surface 2B of the wall member 2. In the first embodiment, the anchor piece 3 is a rectangular plate-shaped member, and has a female screw portion 31 (see Figs. 4 and 5) formed in the center. The anchor piece 3 is fixed to the back surface of the wall member 2 at a position where the female screw portion 31 and the mounting hole 23 of the wall member 2 are aligned.

[0035] With the handrail device 1 attached to the wall member 2, the bolt member 7 is inserted into the mounting hole 23 of the wall member 2. The bolt member 7 has a cylindrical bolt body 71 with a male thread portion 72 formed on its outer periphery. The outer diameter of the bolt body 71 is smaller than the inner diameter of the mounting hole 23. For this reason, a gap is generated between the outer periphery of the bolt body 71 and the inner periphery of the mounting hole 23.

[0036] The male thread portion 72 of the bolt member 7 is screwed into the female thread portion 31 of the anchor piece 3 at the rear side (the rear surface 2B side of the wall member 2). A nut member 73 is screwed into the male thread portion 72 of the bolt body 71 from the front side.

[0037] Here, the configuration and function of the mounting member 4 will be described. As described above, the mounting member 4 includes the band member 41 and the flange member 45. The flange member 45 has a cylindrical portion 45A and a flange portion 45B extending radially outward from the front side of the cylindrical portion 45A. The outer diameter of the cylindrical portion 45A is smaller than the inner diameter of the mounting hole 23 of the wall member 2. The flange member 45 has a shape that allows the cylindrical portion 45A to be inserted into the mounting hole 23 from the front surface 2A side of the wall member 2 (see FIG. 6). The inner diameter of the cylindrical portion 45A is larger than the outer diameter of the bolt body 71, and has a shape that allows the bolt body 71 to be inserted inside the cylindrical portion 45A.

[0038] In contrast, the outer diameter of flange portion 45B is larger than the inner diameter of mounting hole 23 of wall member 2. Flange member 45 is shaped such that when flange portion 45B contacts surface 2A of wall member 2, flange member 45 cannot be inserted any further into mounting hole 23 and is fitted into mounting hole 23.

[0039] The band member 41 is inserted into the inner peripheral side of the cylindrical portion 45A of the flange member 45, and mutually meshing ratchet teeth are formed on the inner peripheral surface of the cylindrical portion 45A and the outer peripheral surface of the band member 41. These ratchet teeth are formed to permit movement of the flange member 45 relative to the band member 41 in the direction of arrow P1 but to prevent movement in the opposite direction, that is, in the direction of arrow P2.

[0040] Further, a recess into which the band member 41 fits from the radially inside is formed on the inner peripheral surface of the flange member 45. This prevents the flange member 45 from rotating in the circumferential direction (the direction of the arrow R3 shown in FIG. 4) relative to the band member 41.

[0041] A holder 43 is provided on the rear end of the band member 41 via a thin hinge 42 (see FIG. 4). That is, the band member 41 is connected to the anchor piece 3 at the rear side via the holder 43, and is also connected to the flange member 45 at the front side. The mounting member 4 as a whole is designed so that relative rotation or twisting in the circumferential direction of the cylindrical portion 45A does not occur with respect to the anchor piece 3. The holder 43 and the band member 41 are shaped so that they can be inserted into the mounting hole 23 in the process of mounting the handrail device 1 to the wall member 2.

[0042] 4 and 5, the holder 43 is formed in the shape of a rectangular parallelepiped box with one side open so as to be able to partially accommodate the anchor piece 3. Specifically, the holder 43 holds the anchor piece 3 so that the female screw portion 31 is exposed from one end of the anchor piece 3 in the longitudinal direction toward the center. The holder 43 is attached to the band member 41 via a thin hinge 42, so that when the holder 43 is not fixed to the rear surface 2B of the wall member 2, it is rotatable in the direction of arrow R1 shown in FIG. 4 and in the opposite direction, that is, in the direction of arrow R2.

[0043] The holder 43 is provided with an adhesive member 44 on a surface of the holder 43 facing the rear surface 2B of the wall member 2. The adhesive member 44 makes it possible to fix the holder 43 to the rear surface 2B of the wall member 2. As the adhesive member 44, for example, a double-sided adhesive tape can be used, but is not limited thereto.

[0044] A sign portion 8 is provided on the front surface of flange portion 45B of flange member 45. Sign portion 8 is provided in a portion of the circumferential direction of flange portion 45B, for example, by coloring a portion of the front surface.

[0045] As shown in Fig. 3, when the handrail device 1 is attached to the wall member 2, the band member 41 of the mounting member 4 is inserted into the mounting hole 23 of the wall member 2. The band member 41 is interposed between the outer periphery of the bolt body 71 and the inner periphery of the mounting hole 23. When viewed in the direction of arrow N1, the band member 41 has an arc shape that exists in a gap between the outer periphery of the male thread portion 72 and the inner periphery of the mounting hole 23, not in the entire circumferential direction but in a part of it.

[0046] In addition, when the band member 41 is inserted into the mounting hole 23 and the holder 43 is not fixed to the back surface 2B of the wall member 2, the holder 43 and the anchor piece 3 can be rotated in the direction of arrow R3 by rotating the mounting member 4 from the front surface 2A side.

[0047] In a state where the band member 41 is inserted into the mounting hole 23 and the holder 43 is not fixed to the rear surface 2B of the wall member 2, when the anchor pieces 3 rotate in the circumferential direction of the bolt body 71 within the mounting hole 23, the marker portion 8 provided on the flange member 45 also rotates. That is, the rotational position of the anchor pieces 3 corresponds to the rotational position of the marker portion 8. Therefore, the orientation of the anchor pieces 3 can be known by visually checking the position of the marker portion 8. In the example shown in FIG. 7, when viewed in the longitudinal direction of the band member 41 (the direction of the arrow P1 shown in FIG. 5), the position where the anchor pieces 3 are exposed from the holder 43 coincides with the position of the marker portion 8.

[0048] In the first embodiment, in a state in which the anchor piece 3 is fixed to the rear surface 2B of the wall member 2, the band member 41 is cut so that the band member 41 is not exposed on the front side.

[0049] Next, a method for attaching the handrail member 1 to the wall member 2 in this embodiment will be described.

[0050] When attaching the handrail device 1 to a wall member 2, as shown in Fig. 4, a worker inserts the holder 43, anchor piece 3, and band member 41 into the mounting hole 23 of the wall member 2 from the front side. At this time, the holder 43 and anchor piece 3 are placed in a position nearly parallel to the band member 41 (laid down position), and the anchor piece 3 and holder 43 are inserted into the mounting hole 23 with the back side. However, the holder 43 and anchor piece 3 are not completely parallel to the band member 41, but are inclined. This inclined state is maintained by the elasticity of the thin hinge 42, for example.

[0051] As a result, the holder 43, band member 41 and anchor piece 3 are inserted into the mounting hole 23, and the holder 43 is on the back surface 2B side of the wall member 2. In this state, the worker grasps the portion of the mounting member 4 that is located in front of the wall member 2, and rotates the holder 43 and anchor piece 3 in the circumferential direction of the mounting hole 23. At this time, the worker can know the rotational positions of the holder 43 and anchor piece 3 by visually checking the sign portion 8 or the band member 41.

[0052] In the handrail device 1 of the first embodiment, it is preferable that the longitudinal direction of the anchor piece 3 is perpendicular to the extension direction of the handrail member 6 when viewed in the normal direction of the surface 2A of the wall member 2. This is because the attachment strength of the anchor piece 3 to the wall member 2 increases when a force is applied to the handrail member 6 in a direction perpendicular to the extension direction. In this way, the longitudinal direction of the anchor piece 3, which is perpendicular to the extension direction of the handrail member 6, is the "specific direction" in this embodiment.

[0053] With the direction of the anchor piece 3 set in this way, the worker pulls the band member 41 towards himself. Since the holder 43 and the anchor piece 3 are inclined with respect to the band member 41, the holder 43 rotates in the direction of arrow R1 around the thin hinge 42 with respect to the band member 41 while the end of the anchor piece 3 (the end opposite the holder 43) comes into contact with the back surface 2B of the wall member 2. Then, due to this rotation, the holder 43 assumes a position parallel to the back surface 2B of the wall member 2. With the holder 43 parallel to the back surface 2B of the wall member 2, the anchor piece 3 housed in the holder 43 also assumes a position parallel to the back surface 2B of the wall member 2.

[0054] 5, with the holder 43 parallel to the back surface 2B of the wall member 2, the adhesive member 44 of the holder 43 is fixed to the back surface 2B of the wall member 2. This causes the anchor piece 3 to be engaged with the back surface 2B of the wall member 2. The centers of the female screw portion 31 of the anchor piece 3 and the mounting hole 23 of the wall member 2 are aligned.

[0055] Then, the flange member 45 is moved toward the rear side relative to the band member 41 and fitted into the mounting hole 23 of the wall member 2 (see FIG. 6). Since ratchet teeth are formed on the band member 41 and the flange member 45, the flange member 45 will not move toward the front side relative to the band member 41 from this state.

[0056] Here, the worker cuts and removes a part of the band member 41. In the first embodiment, at least the part of the band member 41 that is located on the front side of the flange member 45 is removed.

[0057] Then, the bolt body 71 is inserted into the mounting hole 23 of the wall member 2 from the cylindrical portion 45A of the flange member 45, and further, the male thread portion 72 of the bolt body 71 is screwed into the female thread portion 31 of the anchor piece 3. The front side portion of the bolt body 71 is adjusted so as to protrude further forward than the base portion 53 of the bracket member 5.

[0058] The worker brings the bracket member 5 into contact with or faces the surface 2A of the wall member 2, with the base portion 53 parallel to the surface 2A of the wall member 2 and with the extension direction of the handrail member 6 in a predetermined direction. At this time, the bolt body 71 is inserted into the insertion hole 54.

[0059] A viewing hole 55 is formed in the base portion 53 of the bracket member 5. As shown in Fig. 8, when the holder 43 and the anchor piece 3 are in a specific direction, the marker portion 8 can be seen through the viewing hole 55. In contrast, as shown in Fig. 9, when the holder 43 and the anchor piece 3 are not in a specific direction, the position of the marker portion 8 is shifted from the viewing hole 55, and therefore the marker portion 8 cannot be seen through the viewing hole 55. In other words, by viewing the marker portion 8 through the viewing hole 55, the worker can know that the anchor piece 3 is in a specific direction.

[0060] The front part of the bolt body 71 protrudes further forward than the base part 53 of the bracket member 5. The worker screws the nut member 73 into this protruding part. As a result, the wall member 2 and the base part 53 of the bracket member 5 are sandwiched between the anchor piece 3 and the bolt member 7. That is, the bolt member 7 fastens the wall member 2 and the base part 53 of the bracket member 5 together with the anchor piece 3. As a result, the bracket member 5 is fixed to the wall member 2 on the surface 2A side, and the handrail member 6 is also fixed to the surface 2A of the wall member 2 at one end side in the extension direction. The other end side in the extension direction of the handrail member 6 is also fixed to the surface 2A of the wall member 2 in the same manner as the one end side.

[0061] The holder 43 holding the anchor piece 3 is fixed to the rear surface 2B of the wall member 2 by the adhesive member 44. Therefore, when the nut member 73 is screwed into the bolt body 71, the anchor piece 3 is prevented from rotating together with the bolt body 71.

[0062] Next, the operation and effects of this embodiment will be described. In the handrail device 1 of the first embodiment, with the holder 43, band member 41 and anchor piece 3 inserted into the mounting hole 23 and the holder 43 and anchor piece 3 on the back surface 2B side of the wall member 2, the worker can grasp the portion of the mounting member 4 that is located in front of the wall member 2. As a result, in the handrail device 1 of the first embodiment, by grasping the holder 43, the worker can rotate the holder 43 and anchor piece 3 in the circumferential direction of the mounting hole 23 and adjust the rotational position of the anchor piece 3.

[0063] At this time, the worker cannot see the holder 43 and the anchor piece 3 from the front side (the surface 2A side of the wall member 2). However, by visually checking the sign portion 8 or the band member 41, the worker can know the rotational positions of the holder 43 and the anchor piece 3. Therefore, it is easy to check whether the anchor piece 3 is in a specified rotational position.

[0064] Moreover, in the handrail device 1 of the first embodiment, a viewing hole 55 is formed in the base portion 53 of the bracket member 5. That is, even when the bracket member 5 is in contact with or facing the surface 2A of the wall member 2, the worker can visually check the sign portion 8 through the viewing hole 55 and know that the anchor piece 3 is in a specific rotation position.

[0065] In the handrail device 1 of the first embodiment, the insertion hole 54 and the viewing hole 55 are provided separately. Therefore, the insertion hole 54 can have a shape suitable for inserting the bolt member 7, and the viewing hole 55 can have a shape suitable for viewing the characteristic part.

[0066] Even if the visualization hole 55 is covered by the nut member 73, the operator can view the visualization hole 55 by removing the nut member 73 from the bolt body 71. Alternatively, the visualization hole 55 may be formed at a position that is not covered by the nut member 73, so that the visualization hole 55 can be viewed even when the nut member 73 is screwed into the bolt body 71.

[0067] In the handrail device 1 of the first embodiment, the sign portion of the disclosed technology is the sign portion 8 provided on the flange member 45. That is, with the simple structure of providing the sign portion 8 on the flange member 45, the characteristic portion can be provided on the mounting member 4.

[0068] Second Embodiment Next, a second embodiment will be described. In the second embodiment, the same elements, members, etc. as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof will be omitted.

[0069] As shown in FIG. 10, in the handrail device 12 of the second embodiment, a viewing hole 56 that is continuous with the insertion hole 54 is formed in the base portion 53 of the bracket member 5 instead of the viewing hole 55 of the first embodiment.

[0070] In the handrail device 12 of the second embodiment, the front end 41A of the band member 41 is located within the range of the thickness T1 (see FIG. 2) of the base portion 53 of the bracket member 5. In the example shown in FIG. 10, the end 41A of the band member 41 is located at the same position as the front end face 53A of the base portion 53. The viewing hole 56 is formed so that the front end 41A of the band member 41 is accommodated when the anchor piece 3 is in a specific rotation position. That is, in the handrail device 12 of the second embodiment, the front end 41A of the band member 41 is a portion that protrudes toward the front surface 2A side of the wall member 2 and reaches the viewing hole 56. In the handrail device 12 of the second embodiment, this end 41A is an example of a characteristic part of the disclosed technology.

[0071] In the handrail device 12 of the second embodiment, the marker portion 8 is not provided on the flange member 45.

[0072] In the second embodiment thus configured, the handrail device 1 can be attached to the front surface 2A side of the wall member 2 in a manner similar to that of the first embodiment. However, in the second embodiment, when cutting and removing a portion of the front side of the band member 41, the cut is made on the front side of the end face 45C of the flange member 45. Specifically, the front end 41A of the band member 41 is set to be within the range of the thickness T1 of the base portion 53 of the bracket member 5. This makes it possible to confirm that the anchor piece 3 is in a specific rotation position by visually checking the end 41A of the band member 41 through the viewing hole 56 of the bracket member 5, as shown in FIG.

[0073] In the handrail device 12 of the second embodiment, the insertion hole 54 and the viewing hole 56 are continuous with each other. Since the insertion hole 54 and the viewing hole 56 can be integrated without being provided separately, the structure of the bracket member 5 can be simplified, and further the structure of the handrail device 12 as a whole can be simplified.

[0074] In the handrail device 12 of the second embodiment, the portion of the band member 41 that protrudes from the flange member 45 toward the front surface 2A of the wall member 2 and reaches the viewing hole is the sign portion 8. That is, a characteristic portion can be provided on the mounting member 4 as a part of the band member 41.

[0075] In the second embodiment, the modified configuration shown in Fig. 12 and Fig. 13 may be used. In the modified handrail device 13, in a structure in which the sign portion 8 is provided on the end surface 45C of the flange member 45, as in the handrail device 1 of the first embodiment, the insertion hole 54 and the viewing hole 56 are continuous as in the handrail device 12 of the second embodiment. However, the viewing hole 56 is shaped so that the sign portion 8 can be easily viewed from the front side. This allows the structure of the bracket member 5 to be simplified even in a structure in which the sign portion 8 is provided on the end surface 45C of the flange member 45, and further allows the structure of the handrail device 13 to be simplified.

[0076] 12 and 13, the direction in which the viewing hole 56 is connected to the insertion hole 54 is the same as the extension direction of the handrail member 6. In other words, when a force is applied in a direction perpendicular to the handrail member 6, the insertion hole 54 does not expand in the direction of the force. Therefore, when a force is applied in a direction perpendicular to the handrail member 6, rattling of the bolt body 71 with respect to the insertion hole 54 is suppressed. In this case, the position of the sign portion 8 may be rotated 90 degrees from the example shown in FIG. 8 in accordance with the viewing hole 56. [Explanation of symbols]
