[0007] The problem to be solved by the utility model

[0008] However, since the crossbeam material 2 and the outer casing 7 of the lighting unit 3 are cut at the construction site, the handrail crossbeam is not actually constructed during the above-mentioned process. At the construction site, firstly, the connecting auxiliary material 32 is installed at the mounting position of the bracket 21 inside the cut portion 1 of the crossbeam material 2 using fixing screws 33. Next, the connecting auxiliary material 32 is fixed to the mounting piece 30 of the bracket 21 fixed to the wall 22 using screws 31. Then, the outer casing 7 is fixed inside the cut portion 1 of the crossbeam material 2, and lighting components such as the light source unit 4 and the power supply cable 5 are installed on the outer casing 7.

[0009] However, when the power supply cable 5 is passed through the connecting auxiliary material 32, it is necessary to avoid damaging the power supply cable 5 due to the fixing screws 33 and 31 protruding into the connecting auxiliary material 32 (cut-out portion 1), which would cause wiring difficulties.

[0010] This disclosure takes into account the above facts and aims to provide a bracket and handrail device in which the mounting position of the bracket in the handrail crossbeam facilitates cable routing.

[0011] Solution for solving the problem

[0012] The bracket of the first embodiment comprises: a bracket body provided at a mounting base and having an extension extending upward; a receiving member installed at the upper end of the extension and housed in the groove of a handrail crossbar with a groove formed at the lower end, having a pair of side plates facing each other across the upper end of the extension and an opening at the bottom; and a mounting portion provided at the upper end of the extension and joined to the pair of side plates in a state at least partially separated by a support portion, wherein the receiving member is capable of swinging relative to the mounting portion about the support portion.

[0013] In the bracket of the first type, the mounting portion of the extension and the opposing side plates of the receiving component are at least partially separated. That is, a gap is formed between the mounting portion of the extension and the side plates of the receiving component, allowing for the routing of cables along the length of the crossbar handrail.

[0014] Because of the opening at the bottom of the receiving component, cable routing is easy. In addition, since the gap between the mounting part of the extension and the side plate of the receiving component can be seen through the opening, it is easy to pass the cable through the gap.

[0015] Furthermore, since the supporting components can swing around the support, the horizontal handrail can be tilted to the desired angle.

[0016] The second type of bracket is based on the first type of bracket, wherein the receiving component is configured to include a pair of side plate portions that face the walls on both sides of the groove of the handrail crossbar, and a base plate portion that connects the upper ends of the pair of side plate portions to each other and fixes them to the bottom of the groove of the handrail crossbar.

[0017] In the second type of bracket, when the base plate of the receiving component is fixed to the bottom of the groove of the handrail crossbar, it can be installed in such a way that the threaded part of the fixing screw does not protrude into the receiving component (groove).

[0018] The third type of bracket is based on the second type of bracket, wherein an abutment portion is provided at the upper end of the mounting portion, and a window portion is formed on the base plate portion to expose the abutment portion, and the abutment portion exposed from the window portion abuts against the bottom of the groove of the handrail crossbar.

[0019] In the third-party bracket, the abutment portion located at the upper end of the mounting portion protrudes from the window portion formed on the base plate portion of the receiving component. The abutment portion protruding from the window portion abuts against the bottom of the groove of the handrail crossbar, so that the load from the handrail crossbar can be received by the abutment portion of the bracket.

[0020] The fourth type of bracket is based on the third type of bracket, wherein the aforementioned abutment portion is configured to include an arc shape centered on the aforementioned support portion.

[0021] In the fourth type of bracket, since the handrail crossbar held by the receiving component swings along the arc shape of the abutment, the load from the handrail crossbar that is inclined relative to the bracket can also be accepted by the abutment of the bracket.

[0022] The fifth type of bracket is based on any of the first to fourth types of brackets, wherein the support portion is provided on a boss portion that protrudes from the mounting portion toward the side plate portion.

[0023] In the bracket of the fifth type, since a boss protrudes from the mounting part toward the side plate part, the gap between the mounting part and the side plate part is maintained. Furthermore, a cable can be inserted into this gap along the boss part.

[0024] The sixth type of bracket is based on any of the first to fourth types of brackets, wherein the support portion is inserted into a gasket disposed between the mounting portion and the side plate portion and is mounted on the mounting portion.

[0025] In the bracket of the sixth type, a gasket is placed between the mounting part and the side plate part to maintain the gap between them. Furthermore, a cable can be inserted into this gap along the gasket.

[0026] The seventh type of bracket is based on any of the first to fourth types of brackets, wherein it has a cover that is fitted to a pair of the aforementioned side plates and seals the openings of the aforementioned receiving components.

[0027] In the seventh type of bracket, the interior of the receiving component can be hidden by a cover.

[0028] The handrail device of the eighth type has: a plurality of the aforementioned brackets of any one of the first to seventh types; and a handrail crossbar fixed to the plurality of the aforementioned brackets.

[0029] In the eighth type of handrail device, the cable routing becomes easier at the mounting position of the bracket in the handrail crossbeam.

[0030] The effects of the utility model are as follows.

[0031] According to the bracket and handrail device disclosed herein, cable routing at the bracket installation location in the handrail crossbar becomes easier. Attached Figure Description

Detailed Implementation

[0041] Hereinafter, the methods for implementing this disclosure will be described based on the accompanying drawings. Components indicated by the same symbols in the various drawings refer to the same or identical components. Furthermore, there are instances where descriptions and symbols repeated in the embodiments described below are omitted. Also, the drawings used in the following description are schematic drawings, and the dimensional relationships and ratios of the components shown in the drawings may not necessarily correspond to reality. Furthermore, the dimensional relationships and ratios of the components may not necessarily be consistent between multiple drawings.

[0042] The following description, based on the accompanying drawings, illustrates the methods for implementing this disclosure.

[0043] like Figures 1 to 3 As shown, the handrail device 10 of this embodiment includes a handrail crossbar 20 and a bracket 30. The handrail crossbar 20 includes a crossbar lighting device 60, a cover 70, and a lighting cover 73.

[0044] (handrail crossbar)

[0045] The handrail crossbar 20 is, for example, a long, generally cylindrical component that forms the main part of the walking aid handrail, and is supported by multiple brackets 30. A rectangular groove 21 is provided on the bottom side of the handrail crossbar 20 along its length to accommodate a lighting device 60 or similar fixture. The groove 21 is continuously formed along the entire length of the handrail crossbar 20. The outer peripheral surface 22 of the handrail crossbar 20, except for the groove 21, is, for example, a cylindrical surface.

[0046] (bracket)

[0047] like Figure 4 As shown, the bracket 30 is configured to include a bracket body 30A and a receiving component 40. In this embodiment, the bracket 30 is mounted on a wall surface 80, which serves as a mounting base, as an example.

[0048] In the bracket body 30A of this embodiment, for example, the base 32 extending horizontally and the extension extending upward from the base 32 are integrally formed. Specifically, a thick-walled, plate-like extension 33 extending upward in a direction intersecting the base 32 is integrally provided at the front end of the base 32. The bracket body 30A is formed of, for example, a metal material. Furthermore, a washer 31 is provided between the wall surface 80 and the base 32 as needed.

[0049] like Figure 1 and Figure 2 As shown, the upper part of the extension 33 (formed as a roughly triangular, mountain-shaped portion) is provided as a mounting part 331 for mounting the receiving component 40. Cylindrical bosses 34 protrude from the side plates 41 of the mounting part 331 toward the receiving component 40. An internal thread 35 is formed at the center of the bosses 34.

[0050] like Figure 1 and Figure 4 As shown, the receiving member 40 is a strip-shaped component with a cross-section in the shape of a "ko" that includes a pair of opposing side plate portions 41 and a base plate portion 42 connecting the upper ends of the pair of side plate portions 41 to each other. As an example, the receiving member 40 is formed of a metal plate.

[0051] like Figure 4 As shown, a rectangular window 43 is formed in the center of the substrate portion 42 of the receiving component 40 in the longitudinal direction, and holes 44 are formed at both ends of the substrate portion 42 in the longitudinal direction. Figure 1 As shown, a hole 45 is formed in the side plate portion 41 of the receiving component 40 at its central portion along the longitudinal direction for inserting the threaded portion 51 of a countersunk screw 50. Furthermore, the hole 45 is countersunk to accommodate the head 52 of the countersunk screw 50. In addition, the countersunk screw 50 is an example of a support portion of this disclosure.

[0052] like Figure 4As shown, the receiving component 40 is configured as the mounting portion 331 of the cover bracket 30, and a pair of side plate portions 41 are positioned opposite each other across the mounting portion 331. Furthermore, as... Figure 1 As shown, the threaded portion 51 of the countersunk screw 50, which is inserted into the hole 45 of the receiving member 40, is threaded into the internal thread 35 of the boss portion 34 of the mounting portion 331, thereby mounting the receiving member 40 onto the mounting portion 331 of the bracket 30. Figure 2 As shown, the handrail crossbar 20 installed on the receiving component 40 can rotate and tilt in the direction of arrow A with the countersunk screw 50 (support part) as the center.

[0053] The side plate portion 41 of the receiving member 40 abuts against the top of the boss portion 34, which protrudes from the side of the mounting portion 331. Furthermore, a gap S1 is formed between the planes 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 opening on the lower side of the receiving member 40, whose cross-section is formed in the shape of a "ko".

[0054] When the receiving component 40 is installed in the mounting portion 331 of the bracket 30 as shown, then... Figure 2 and Figure 4 As shown, the abutting portion 332 of the mounting portion 331 of the bracket 30 protrudes from the window portion 43 of the base plate portion 42 of the receiving member 40. Furthermore, the details of the abutting portion 332 will be described below.

[0055] In bracket 30, such as Figure 1 and Figure 2 As shown, the receiving component 40 is inserted into the groove 21 of the handrail crossbar 20, and the base plate portion 42 of the receiving component 40 abuts against the bottom of the groove 21. Furthermore, the hole 44 inserted into the base plate portion 42 (see reference) Figure 4 The self-tapping screw 47 in the bracket is screwed into the lower hole (not shown) at the bottom of the groove 21, thereby installing the handrail crossbar 20 on the receiving part 40. In this embodiment, the handrail crossbar 20 is installed on the receiving part 40 in this way, so that the abutting portion 332 of the bracket 30 exposed from the window portion 43 of the base plate portion 42 abuts against the bottom of the groove 21 of the handrail crossbar 20.

[0056] like Figure 2 As shown, the upper edge of the mounting part 331 has an arc-shaped edge 334 formed with a radius R centered on the axis of the countersunk screw 50 (support part).

[0057] Furthermore, the upper edge of the mounting portion 331 has straight inclined edges 333 on both sides of the arc-shaped edge portion 334, which are inclined relative to the horizontal direction (inclination angle θ). The arc-shaped edge portion 334 and the inclined edge portion 333 are set as abutting portions 332 that abut against the bottom surface of the groove 21 of the handrail crossbar 20. The inclination angle θ is set to about 30 degrees to 50 degrees.

[0058] Since the arcuate edge 334 of the bracket 30 exposed from the window 43 of the base plate 42 is an arcuate shape centered on the axis of the countersunk screw 50 (support), even if the handrail crossbar 20 is tilted, the abutment 332 will always contact the bottom of the groove 21.

[0059] In addition, such as Figure 5 As shown, the receiving member 40 can be tilted until the bottom of the groove 21 abuts against the inclined edge 333 of the mounting portion 331 provided on the bracket 30. In other words, the inclined edge 333 serves as a limiting member to restrict the tilting of the receiving member 40.

[0060] like Figure 2 As shown, a lighting device 60 for the handrail crossbar 20, which includes a light source such as an LED, is housed between two brackets in the groove 21 of the handrail crossbar 20. In this embodiment, a housing component with an opening at the bottom is fixed to the groove 21 of the handrail crossbar 20, the lighting device 60 for the crossbar is provided on the housing component, and a light-transmitting lighting cover 73 is provided at the opening of the housing component.

[0061] like Figure 1 and Figure 2 As shown, a power supply cable 61 for supplying power to the lighting device 60 for the handrail is routed through the groove 21 of the handrail crossbeam 20. The power supply cable 61, which runs across the bracket 30 in the length direction of the handrail crossbeam 20, is routed through the gap S1 between the mounting part 331 of the bracket 30 and the receiving part 40 on the upper side of the boss 34.

[0062] like Figure 2 As shown, the lighting device 60 for the crossbeam is electrically connected to the power supply cable 61 via a connecting cable 62 and a wiring portion 63. Figure 2 As shown, a portion of the power supply cable 61, the connecting cable 62, and the wiring portion 63 may also be disposed inside the receiving component 40.

[0063] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a cover 70 is installed on the side plate portion 41 of the receiving component 40 to block the opening of the receiving component 40. The cover 70 has a pair of locking plates 71 and a connecting plate portion 72 that connects the lower ends of the pair of locking plates 71 to each other, and is a component with a "ko" shaped cross section. The cover 70 is an example of the cover of this disclosure.

[0064] like Figure 1 As shown, the width of the receiving component 40 is slightly narrower than the width of the groove 21 of the handrail crossbar 20, so that the locking plate portion 71 of the cover 70 can be inserted into the gap between the side of the groove 21 and the side plate portion 41 of the receiving component 40. Figure 6As shown, covers 70 are provided on both sides of the extension 33 of the bracket 30 of the receiving component 40. Specifically, when the connecting plate portion 72 is in contact with or close to the extension 33 of the bracket 30, the locking plate portion 71 is installed on the side plate portion 41 of the receiving component 40.

[0065] Furthermore, the cover 70 is fixed to the receiving member 40 by bonding the locking plate portion 71 to the side plate portion 41 of the receiving member 40, but it can also be fixed by fitting or other means without using adhesive. Also, the locking plate portion 71 of the cover 70 can be bonded to the groove 21 of the handrail crossbar 20. Here, as... Figure 5 As shown, when the receiving member 40 is tilted relative to the horizontal, the length of the openings on both sides of the receiving member 40 across the extension 33 changes. In the cover 70 of this disclosure, the locking plate 71 can be installed on the side plate 41 of the receiving member 40 while the connecting plate 72 is in contact with or close to the extension 33 of the bracket 30, so that the openings on both sides of the receiving member 40 across the extension 33 can be sealed regardless of the tilt angle.

[0066] like Figure 2 As shown, the cover 70 conceals the power supply cable 61 and other components housed inside the receiving component 40. Therefore, as... Figure 3 As shown, even when viewing the handrail device 10 from bottom to top, the power supply cable 61 and the like are not visible. Furthermore, the cover 70 that blocks the opening of the receiving component 40 can also simultaneously block the opening of the groove 21 at the position corresponding to the receiving component 40.

[0067] Furthermore, a housing component for accommodating a lighting device 60 for the crossbeam 20 is provided in the groove 21 of the handrail crossbeam 20 as described above, and the opening of the groove 21 is sealed by a lighting cover 73 disposed in the opening of the housing component.

[0068] (Function, Effect)

[0069] This embodiment is configured as described above, and its function and effect will be explained below together with the assembly sequence of the handrail device 10.

[0070] (1) First, the direction of the bracket 30 is initially determined so that the extension 33 is in the vertical direction and multiple brackets 30 are installed on the wall surface 80 at predetermined intervals.

[0071] (2) Next, the receiving part 40 of the bracket 30 is inserted into the groove 21 of the handrail crossbar 20, and the self-tapping screw 47 inserted in the hole 44 of the receiving part 40 is screwed into the lower hole (not shown) formed at the bottom of the groove 21, thereby installing the handrail crossbar 20 on the receiving part 40.

[0072] (3) Then, the power supply cable 61 is wired into the groove 21 of the handrail crossbeam 20, and the lighting device 60 for the crossbeam is installed.

[0073] In summary, according to this embodiment, since the abutting portion 332 of the bracket 30 exposed from the window portion 43 of the receiving member 40 contacts the bottom of the groove 21 of the handrail crossbar 20 (see reference...), Figure 7 The load from the handrail crossbar 20 is received by the abutment portion 332 of the bracket 30, thus reducing the load applied to the countersunk screw 50 (support portion).

[0074] The groove 21 of the handrail crossbar 20 has a portion for receiving component 40. A gap S1 is provided between the side plate portion 41 of the receiving component 40 and the side of the mounting portion 331 of the bracket 30. The gap S1 communicates with the opening on the lower side of the receiving component 40.

[0075] Therefore, in the part where the receiving component 40 is provided, the operator can see the interior of the receiving component 40, namely the gap S1 for wiring the power supply cable 61, through the opening on the lower side of the receiving component 40, and can insert the power supply cable 61 into the gap S1 along the boss portion 34. Thus, the power supply cable 61 can be easily wired through the gap S1 on the upper side of the boss portion 34.

[0076] In this embodiment, since the power supply cable 61 is routed through the gap S1 on the upper side of the boss portion 34 inside the receiving member 40, the boss portion 34 can suppress the power supply cable 61 from falling (slackening downwards) inside the receiving member 40.

[0077] [Other Implementation Methods]

[0078] The above describes one example of an embodiment of the present disclosure. However, the embodiments of the present disclosure are not limited to the above-described embodiments. Of course, various modifications can be made without departing from the spirit of the subject.

[0079] In the above embodiment, bosses 34 are formed on both sides of the mounting portion 331. However, a gasket with a thickness equivalent to the thickness of the gap S1 can be provided on both sides of the mounting portion 331 instead of providing a pair of bosses 34 on the mounting portion 331.

[0080] Furthermore, bosses 34 or gaskets are provided on the two sides of the mounting portion 331, but the bracket 30 can also be formed by providing a boss 34 or gasket on one side of the mounting portion 331 and having the other side of the mounting portion 331 in contact with the side plate portion 41.

[0081] In the above embodiments, an example of a wall-mounted bracket for wall mounting has been described as a bracket of this disclosure, but this disclosure is not limited to this. For example, it can also be applied to a support bracket for mounting on the upper part or side of a handrail support. The handrail crossbar is not limited to a cylindrical shape, but may also be a square tube shape. Furthermore, the handrail crossbar is not limited to a tubular component, but may also be a solid component with grooves.
