Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the coping material 2, the case 7 of the lighting unit 3, etc. are cut at the construction site, in reality, the handrail coping is not constructed by the above-described process. At the construction site, first, a connection auxiliary member 32 is attached to the attachment position of the bracket 21 in the notch 1 of the coping material 2 with a fixing screw 33. Next, this connection auxiliary member 32 is fixed to the attachment piece 30 of the bracket 21 fixed to the wall surface 22 by a screw 31. Then, the case 7 is fixed in the notch 1 of the coping material 2, and lighting components such as a light source unit 4 and a power supply cable 5 are provided in this case 7. By the way, when passing the power supply cable 5 through the connection auxiliary member 32, it is necessary to avoid damaging the power supply cable 5 by the fixing screw 33 or the screw 31 protruding into the connection auxiliary member 32 (notch portion 1), and there has been a problem that wiring is difficult.

[0005] In consideration of the above facts, an object of the present disclosure is to provide a bracket and a handrail device that facilitate cable wiring at the attachment position of the bracket on the handrail coping.

Means for Solving the Problems

[0006] The bracket according to the first aspect includes a bracket main body provided on a mounting base portion and having an extension portion extending upward, and a handrail coping having a concave groove formed in a lower portion thereof is attached to an upper end portion of the extension portion. A receiving member that is accommodated in the concave groove to hold the handrail coping, and includes a pair of side plate portions facing each other via the upper end portion of the extension portion and having an open lower portion, and an attachment portion provided at the upper end portion of the extension portion and coupled by a support portion in a state of being at least partially separated from the pair of side plate portions. The receiving member is relatively swingable about the support portion with respect to the attachment portion.

[0007] In the bracket according to the first aspect, the attachment portion of the extension portion is at least partially separated from the side plate portions of the receiving member facing each other. That is, a gap is formed between the attachment portion of the extension portion and the side plate portion of the receiving member through which a cable can be wired in the longitudinal direction of the coping handrail.

[0008] Since the receiving member has an open lower portion, it is easy to perform cable wiring work. Also, since the gap between the attachment portion of the extension portion and the side plate portion of the receiving member can be seen from this opening, it becomes easy to pass the cable through this gap. Further, since the receiving member is swingable about the support portion, the coping handrail can be inclined at a desired angle.

[0009] The bracket according to the second aspect is the bracket according to the first aspect, wherein the receiving member includes a pair of side plate portions respectively facing the wall surfaces on both sides of the concave groove of the handrail coping, and an upper end of the pair of side plate portions are connected to each other, and a substrate portion fixed to the bottom of the concave groove of the handrail coping.

[0010] In the bracket according to the second aspect, when the substrate portion of the receiving member is fixed to the bottom of the concave groove of the handrail coping, it can be attached so that the screw portion of the fixing screw does not protrude into the receiving member (concave groove).

[0011] The bracket according to the third aspect is the bracket according to the second aspect, wherein a contact portion is provided at the upper end of the attachment portion, a window portion for exposing the contact portion is formed in the substrate portion, and the contact portion exposed from the window portion contacts the bottom of the concave groove of the handrail coping.

[0012] In the bracket according to the third aspect, the contact portion provided at the upper end of the attachment portion is exposed from the window portion formed in the substrate portion of the receiving member, and the contact portion exposed from the window portion contacts the bottom of the concave groove of the handrail coping, so that the load from the handrail coping can be received by the contact portion of the bracket.

[0013] The bracket according to the fourth aspect is the bracket according to the third aspect, wherein the contact portion is configured to include an arc shape centered on the support portion.

[0014] In the bracket according to the fourth aspect, since the handrail coping held by the receiving member swings along the arc shape of the contact portion, the load from the handrail coping inclined with respect to the bracket can also be received by the contact portion of the bracket.

[0015] The bracket according to the fifth aspect is the bracket according to any one of the first aspect to the fourth aspect, wherein the support portion is provided on a boss portion protruding from the attachment portion toward the side plate portion.

[0016] In the bracket according to the fifth aspect, since the boss portion protrudes from the mounting portion toward the side plate portion, the gap between the mounting portion and the side plate portion is maintained. Further, the cable can be inserted into this gap along the boss portion.

[0017] The bracket according to the sixth aspect is the bracket according to any one of the first aspect to the fourth aspect, wherein the support portion is inserted through a washer disposed between the mounting portion and the side plate portion and attached to the mounting portion.

[0018] In the bracket according to the sixth aspect, since a washer is disposed between the mounting portion and the side plate portion, the gap between the mounting portion and the side plate portion is maintained. Further, the cable can be inserted into this gap along the washer.

[0019] The bracket according to the seventh aspect is the bracket according to any one of the first aspect to the fourth aspect, and has a cover that is attached to the pair of side plate portions and closes the opening of the receiving member.

[0020] In the bracket according to the seventh aspect, the inside of the receiving member can be hidden by the cover.

[0021] The handrail device according to the eighth aspect includes a plurality of the brackets according to any one of the first aspect to the seventh aspect, and the handrail capping fixed to the plurality of the brackets.

[0022] In the handrail device according to the eighth aspect, the wiring of the cable is facilitated at the mounting position of the bracket on the handrail capping.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, embodiments for carrying out the present disclosure will be described with reference to the drawings. Components denoted by the same reference numerals in each drawing mean the same or similar components. In the embodiments described below, duplicate explanations and reference numerals may be omitted. In addition, the drawings used in the following explanations are all schematic, and the dimensional relationships between the respective elements shown in the drawings, the ratios of the respective elements, etc. do not necessarily match the actual ones. Also, the dimensional relationships between the respective elements, the ratios of the respective elements, etc. do not necessarily match even between multiple drawings.

[0026] Hereinafter, embodiments for carrying out the present disclosure will be described with reference to the drawings. As shown in FIGS. 1 to 3, the folding screen device 10 according to the present embodiment has a folding screen lintel 20 and a bracket 30. The folding screen lintel 20 has a lintel lighting device 60, a cover 70, and a lighting cover 73.

[0027] (Folding screen lintel) The handrail capping 20 is, for example, a long, substantially cylindrical member that constitutes a main part of a walking assist handrail, and is supported by a plurality of brackets 30. On the bottom surface side of the handrail capping 20, a rectangular cross-section concave groove 21 for accommodating a capping lighting device 60 or the like is provided in the longitudinal direction. The concave groove 21 is continuously formed over the entire length of the handrail capping 20 in the longitudinal direction. The outer peripheral surface 22 of the handrail capping 20 is, for example, a cylindrical surface except for the concave groove 21.

[0028] (Bracket) As shown in FIG. 4, the bracket 30 is configured to include a bracket main body 30A and a receiving member 40. The bracket 30 of the present embodiment is attached to a wall surface 80 as an example of a mounting base. The bracket main body 30A of the present embodiment is, for example, provided with a base portion 32 extending in the horizontal direction and an extension portion extending upward from the base portion 32 integrally. Specifically, at the tip of the base portion 32, an extension portion 33 having a thick plate shape extending in a direction intersecting the base portion 32, for example, upward, is integrally provided. The bracket main body 30A is formed of, for example, a metal material. Note that a washer 31 is provided between the wall surface 80 and the base portion 32 as necessary.

[0029] As shown in FIGS. 1 and 2, the upper end portion (a mountain-shaped portion formed in a substantially triangular shape) of the extension portion 33 is a mounting portion 331 for attaching the receiving member 40. On both side planes of the mounting portion 331, cylindrical boss portions 34 project toward the side plate portions 41 of the receiving member 40. A female screw 35 is formed at the center of the boss portion 34.

[0030] As shown in FIGS. 1 and 4, the receiving member 40 includes a pair of side plate portions 41 facing each other and a substrate portion 42 connecting the upper ends of the pair of side plate portions 41, and is a long member having a U-shaped cross-section with an open bottom. The receiving member 40 is formed of, for example, a metal plate as an example.

[0031] As shown in Fig. 4, a rectangular window portion 43 is formed in the center in the longitudinal direction of the substrate portion 42 of the receiving member 40, and holes 44 are formed on both ends in the longitudinal direction of the substrate portion 42. As shown in Fig. 1, a hole 45 into which the screw portion 51 of the round head screw 50 is inserted is formed in the center in the longitudinal direction of the side plate portion 41 of the receiving member 40. Further, the hole 45 is subjected to a countersink process for accommodating the head portion 52 of the round head screw 50. Note that the round head screw 50 is an example of the support portion of the present disclosure.

[0032] As shown in Fig. 4, the receiving member 40 is provided so as to cover the mounting portion 331 of the bracket 30, and a pair of side plate portions 41 face each other via the mounting portion 331. Further, as shown in Fig. 1, the receiving member 40 is attached to the mounting portion 331 of the bracket 30 by screwing the screw portion 51 of the round head screw 50 inserted through the hole 45 of the receiving member 40 into the female screw 35 of the boss portion 34 of the mounting portion 331. As shown in Fig. 2, the handrail capping 20 attached to the receiving member 40 can be rotated and inclined in the direction of arrow A about the axis of the round head screw 50 (support portion).

[0033] The side plate portion 41 of the receiving member 40 abuts against the top of the boss portion 34 protruding from the side surface of the mounting portion 331. Further, a gap S1 is formed between the flat surfaces on both sides of the mounting portion 331 and the side plate portion 41 of the receiving member 40. This gap S1 communicates with the lower opening of the receiving member 40 formed in a U-shaped cross section.

[0034] When the receiving member 40 is attached to the mounting portion 331 of the bracket 30 in this way, as shown in Figs. 2 and 4, the contact portion 332 of the mounting portion 331 of the bracket 30 is exposed from the window portion 43 of the substrate portion 42 of the receiving member 40. The details of the contact portion 332 will be described later.

[0035] As shown in FIGS. 1 and 2, the bracket 30 has the receiving member 40 inserted into the concave groove 21 of the handrail coping 20, and the substrate portion 42 of the receiving member 40 is in contact with the bottom of the concave groove 21. Then, a tapping screw 47 inserted through the hole 44 (see FIG. 4) of the substrate portion 42 is screwed into a counterbore (not shown) at the bottom of the concave groove 21, whereby the handrail coping 20 is attached to the receiving member 40. In this embodiment, by attaching the handrail coping 20 to the receiving member 40 in this way, the contact portion 332 of the bracket 30 exposed from the window portion 43 of the substrate portion 42 comes into contact with the bottom of the concave groove 21 of the handrail coping 20.

[0036] As shown in FIG. 2, the upper edge of the mounting portion 331 has an arc-shaped edge portion 334 (radius R) formed in an arc shape centered on the axis of the countersunk head screw 50 (support portion).

[0037] Further, the upper edge of the mounting portion 331 has linear inclined edge portions 333 inclined (inclination angle θ) with respect to the horizontal direction on both sides of the arc-shaped edge portion 334. The arc-shaped edge portion 334 and the inclined edge portions 333 are the contact portion 332 with which the bottom surface of the concave groove 21 of the handrail coping 20 comes into contact. The inclination angle θ is set to about 30 degrees to 50 degrees.

[0038] Since the arc-shaped edge portion 334 of the contact portion 332 of the bracket 30 exposed from the window portion 43 of the substrate portion 42 is in an arc shape centered on the axis of the countersunk head screw 50 (support portion), even if the handrail coping 20 is inclined, the contact portion 332 always comes into contact with the bottom of the concave groove 21.

[0039] Note that, as shown in FIG. 5, the receiving member 40 can be inclined until the bottom of the concave groove 21 comes into contact with the inclined edge portion 333 provided on the mounting portion 331 of the bracket 30. In other words, the inclined edge portion 333 serves as a stopper that limits the inclination of the receiving member 40.

[0040] As shown in Fig. 2, between the two brackets in the concave groove 21 of the handrail coping 20, a coping lighting device 60 configured to include a light source such as an LED is accommodated. In the present embodiment, a case member that opens downward is fixed to the concave groove 21 of the handrail coping 20. The coping lighting device 60 is provided on this case member, and a lighting cover 73 having translucency is disposed at the opening of the case member.

[0041] As shown in Figs. 1 and 2, a power supply cable 61 for supplying power to the coping lighting device 60 is wired in the concave groove 21 of the handrail coping 20. The power supply cable 61 that crosses the handrail coping 20 in the longitudinal direction is wired in a gap S1 between the mounting portion 331 of the bracket 30 above the boss portion 34 and the receiving member 40.

[0042] As shown in Fig. 2, the coping lighting device 60 and the power supply cable 61 are electrically connected via a communication cable 62 and a connection portion 63. As shown in Fig. 2, a part of the power supply cable 61, the communication cable 62, and the connection portion 63 may be disposed inside the receiving member 40.

[0043] As shown in Figs. 1, 2, 4, and 6, a cover 70 that closes the opening of the receiving member 40 is attached to the side plate portion 41 of the receiving member 40. The cover 70 has a pair of locking plate portions 71 and a connecting plate portion 72 that connects the lower ends of the pair of locking plate portions 71, and is a member formed in a U-shaped cross section. The cover 70 is an example of the cover of the present disclosure.

[0044] As shown in Fig. 1, the width of the receiving member 40 is formed slightly narrower than the width of the concave groove 21 of the handrail coping 20 so that the locking plate portion 71 of the cover 70 can be inserted into the gap between the side surface of the concave groove 21 and the side plate portion 41 of the receiving member 40. As shown in Fig. 6, covers 70 are respectively provided on both sides of the receiving member 40 via the extension portion 33 of the bracket 30. Specifically, the locking plate portion 71 is attached to the side plate portion 41 of the receiving member 40 in a state where the connecting plate portion 72 is in contact with or close to the extension portion 33 of the bracket 30.

[0045] Further, the cover 70 is fixed to the receiving member 40 by the locking plate portion 71 being adhered to the side plate portion 41 of the receiving member 40, but it may be fixed by fitting or the like without using an adhesive. Also, the locking plate portion 71 of the cover 70 may be adhered to the concave groove 21 of the handrail coping 20. Here, as shown in FIG. 5, when the receiving member 40 is in a state inclined from the horizontal, the lengths of the opening portions on both sides via the extension portion 33 in the receiving member 40 change. The cover 70 of the present disclosure can attach the locking plate portion 71 to the side plate portion 41 of the receiving member 40 with the connecting plate portion 72 in contact with or close to the extension portion 33 of the bracket 30, so that the opening portions on both sides via the extension portion 33 in the receiving member 40 can be closed regardless of the inclination angle.

[0046] As shown in FIG. 2, the cover 70 hides the power supply cable 61 and the like housed inside the receiving member 40. Therefore, as shown in FIG. 3, even when looking up at the handrail device 10 from below, the power supply cable 61 and the like cannot be seen. Also, the cover 70 that closes the opening of the receiving member 40 can simultaneously close the opening of the concave groove 21 at the position corresponding to the receiving member 40.

[0047] Also, in the concave groove 21 of the handrail coping 20, as described above, a case member for housing the coping lighting device 60 is provided, and the opening of the concave groove 21 is closed by the lighting cover 73 disposed at the opening of this case member.

[0048] (Function, Effect) This embodiment is configured as described above, and its function and effect will be described below together with the assembly procedure of the handrail device 10.

[0049] (1) First, determine the orientation of the bracket 30 so that the extension portion 33 is in the vertical direction, and attach a plurality of brackets 30 to the wall surface 80 at a predetermined interval.

[0050] (2) Next, the receiving member 40 of the bracket 30 is placed in the concave groove 21 of the handrail coping 20 so that it enters the concave groove 21, and a tapping screw 47 inserted through the hole 44 of the receiving member 40 is screwed into a pilot hole (not shown) formed at the bottom of the concave groove 21, thereby attaching the handrail coping 20 to the receiving member 40.

[0051] (3) Then, wiring of the power supply cable 61 and attachment of the coping lighting device 60 and the like are performed with respect to the concave groove 21 of the handrail coping 20.

[0052] As described above, according to the present embodiment, the contact portion 332 of the bracket 30 exposed from the window portion 43 of the receiving member 40 contacts the bottom of the concave groove 21 of the handrail coping 20 (see FIG. 7), and the load from the handrail coping 20 is received by the contact portion 332 of the bracket 30, so that the load on the flat head screw 50 (support portion) can be reduced. In the concave groove 21 of the handrail coping 20, a gap S1 is provided between the side plate portion 41 of the receiving member 40 and the side surface of the attachment portion 331 of the bracket 30 at the portion where the receiving member 40 is provided, and this gap S1 communicates with the lower opening of the receiving member 40. Therefore, at the portion where the receiving member 40 is provided, the operator can see the inside of the receiving member 40 from the lower opening of the receiving member 40, that is, the gap S1 where the power supply cable 61 should be wired, and can insert the power supply cable 61 into this gap S1 along the boss portion 34. Thus, the power supply cable 61 can be easily passed through the upper gap S1 of the boss portion 34 for wiring.

[0053] In the present embodiment, since the power supply cable 61 is wired in the upper gap S1 of the boss portion 34 inside the receiving member 40, the fall (slack downward) of the power supply cable 61 can be suppressed by the boss portion 34 inside the receiving member 40.

[0054] [Other Embodiments] Although an example of the embodiment of the present disclosure has been described above, the embodiments of the present disclosure are not limited to the above, and it goes without saying that various modifications can be made without departing from the gist thereof.

[0055] In the above embodiment, the boss portions 34 are formed on both side planes of the mounting portion 331. However, instead of providing the pair of boss portions 34 on the mounting portion 331, washers having a thickness corresponding to the thickness dimension of the gap S1 may be respectively arranged on both side planes of the mounting portion 331. Also, although the boss portions 34 or washers are provided on both side planes of the mounting portion 331, the bracket 30 may be formed such that the boss portion 34 or washer is provided on one plane of the mounting portion 331 and the other plane of the mounting portion 331 is brought into contact with the side plate portion 41. In the above-described embodiment, an example of applying the present disclosure to a wall-mounted bracket attached to a wall surface as the bracket of the present disclosure has been described. However, the present disclosure is not limited thereto, and for example, it can also be applied to a bracket with a support attached to the upper part or side surface of a handrail support. The handrail capping is not limited to a cylindrical shape and may be a square tube shape. Further, the handrail capping is not limited to a pipe member and may be a solid member having a concave groove.
