[0003] [Patent Document 1] JP 2006-037589 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the handrail of Patent Document 1, it is necessary to operate the coping when removing the surface material from the handrail. From the viewpoint of maintenance, it is desirable that the surface material of the handrail be easily removed. [Means for solving the problem]

[0005] (1) A handrail that solves the above problem is a handrail comprising a panel having a first surface and a second surface opposite the first surface, and an upper frame portion that clamps an upper end portion of the panel, wherein the upper frame portion has a first upper surface material support portion that is provided along the first surface, a second upper surface material support portion that is provided along the second surface, and an upper fastening member that fastens the first upper surface material support portion and the second upper surface material support portion above the upper end portion so as to clamp the upper end portion between the first upper surface material support portion and the second upper surface material support portion.

[0006] According to this configuration, the first upper surface material support part and the second upper surface material support part sandwich the surface material with the upper fastening member, and the surface material is fixed to the upper frame part, so that the surface material can be removed by loosening the upper fastening member. Since the surface material can be conveniently replaced by removing it in this way, the maintainability of the handrail can be improved.

[0007] (2) In the handrail described in (1) above, the upper fastening member overlaps at least one of the first upper surface material support portion and the second upper surface material support portion when viewed from the front.

[0008] According to this configuration, the upper fastening member overlaps with at least one of the first upper surface material support portion and the second upper surface material support portion when viewed from the front, making the upper fastening member less noticeable. This is expected to improve the design of the handrail.

[0009] (3) In the handrail described in (1) or (2) above, a support pillar is provided to support the upper frame portion, and the second upper surface material support portion overlaps with the first upper surface material support portion when viewed from the front and is positioned at a position away from the support pillar in the direction in which the upper frame portion extends.

[0010] According to this configuration, the second upper surface material support portion is positioned offset from the support pillar when viewed from the front, so that the upper fastening member can be positioned so as not to interfere with the support pillar.

[0011] (4) In a handrail described in any one of (1) to (3) above, the upper frame portion includes an upper frame member having a first upper plate-shaped portion arranged above the surface material and the first upper surface material support portion, an upper pressure member having a second upper plate-shaped portion attached to the first upper plate-shaped portion and the second upper surface material support portion, and an upper decorative material overlapping under at least a portion of the upper frame member and the upper pressure member in the vertical direction.

[0012] With this configuration, at least a portion of the upper frame member and the upper pressure member are concealed by the upper decorative material, which is expected to improve the design of the handrail.

[0013] (5) A handrail described in any one of (1) to (4) above, comprising a lower frame portion that clamps the lower end of the panel material, the lower frame portion having a lower frame member having a first lower panel material support portion arranged to conform to the first surface, a lower pressure member having a second lower panel material support portion arranged to conform to the second surface, and a lower engaging member that engages with one of the lower frame member and the lower pressure member so as to clamp the lower end between the first lower panel material support portion and the second lower panel material support portion, the lower engaging member overlapping at least one of the first lower panel material support portion and the second lower panel material support portion when viewed from the front.

[0014] According to this configuration, the lower engaging member overlaps with at least one of the first undersurface material support portion and the second undersurface material support portion when viewed from the front, making the lower engaging member less noticeable. This is expected to improve the design of the handrail.

[0015] (6) The handrail described in (5) above is provided with a support pillar supporting the upper frame portion, and the second underside material support portion overlaps with the first underside material support portion when viewed from the front and is positioned at a position away from the support pillar in the direction in which the lower frame portion extends.

[0016] According to this configuration, the second undersurface material support portion is positioned offset from the support pillar when viewed from the front, so that the second undersurface material support portion can be positioned so as not to interfere with the support pillar.

[0017] (7) In the handrail described in (5) or (6) above, the lower frame member has a first lower plate-shaped portion arranged below the face material, the lower pressure member has a second lower plate-shaped portion attached to the first lower plate-shaped portion, and the lower frame portion has a bottom decorative material overlapping at least a portion of the lower frame member and the lower pressure member in the vertical direction.

[0018] With this configuration, at least a portion of the lower frame member and the lower pressure member are concealed by the bottom decorative material, which is expected to improve the design of the handrail.

[0019] (8) A handrail described in any one of (1) to (7) above, comprising a support post supporting the upper frame portion and two adjacent panel materials, the two panel materials being arranged so that a gap is provided between a lateral end portion of one panel material and a lateral end portion of the other panel material, and the gap is arranged so that it overlaps with the support post when viewed from the front.

[0020] With this structure, the gap between the two panels overlaps with the support post when viewed from the front, making the gap less noticeable when viewed from the front. Because the gap is less noticeable, the two panels appear to be connected, which is expected to improve the design of the handrail. Effect of the Invention

[0021] The handrail of the present disclosure can improve maintainability. [Brief description of the drawings]

The second lower surface material support portion 422 is formed in a plate shape extending upward from the second lower plate-shaped portion 421. The second lower surface material support portion 422 contacts the second surface 20B of the panel material 20 via the second lower cushioning material 45. A third lower cushioning material 46 is provided between the panel material 20 and the lower frame portion 40. The second lower surface material support portion 422 overlaps with the first lower surface material support portion 412 in a front view, and is disposed at a position away from the support 12.

[0058] The lower pressing member 42 has a second rising portion 423. The second rising portion 423 is formed integrally with the second lower plate-shaped portion 421 so as to extend upward from the second lower plate-shaped portion 421. The second rising portion 423 is located on the second space S2 side with respect to the face material 20 in the vertical direction. The second rising portion 423 is located between the face material 20 and the first rising portion 413 of the lower frame member 41 in the vertical direction. A lower engagement portion 424 is provided on the second rising portion 423. The lower engagement member 43 engages with the lower engagement portion 424. The lower engagement portion 424 is, for example, a screw hole.

[0059] The lower engagement member 43 engages with one of the lower frame member 41 and the lower holding member 42 so as to clamp the lower end portion 23 between the first lower surface member support portion 412 and the second lower surface member support portion 422. In this embodiment, the lower engagement member 43 engages with the lower holding member 42. The lower engagement member 43 is, for example, a bolt. The bolt of the lower engagement member 43 is arranged so that the head of the bolt faces toward the first space S1. The bolt of the lower engagement member 43 engages with a lower engagement portion 424 provided on the second rising portion 423 of the lower holding member 42. The tip portion of the bolt which is the lower engagement member 43 contacts the first rising portion 413 of the lower frame member 41.

[0060] When the bolt of the lower engagement member 43 is screwed into the screw hole of the lower engagement portion 424, the tip of the bolt, which is the lower engagement member 43, presses the first rising portion 413. When the tip of the bolt, which is the lower engagement member 43, presses the first rising portion 413, the lower holding member 42 moves in a direction from the second space S2 toward the first space S1. When the lower holding member 42 moves in a direction from the second space S2 toward the first space S1, the second lower surface material support portion 422 is pressed against the second surface 20B of the panel material 20. When the lower holding member 42 presses the second lower surface material support portion 422 against the second surface 20B of the panel material 20, the first lower surface material support portion 412 and the second lower surface material support portion 422 clamp the panel material 20.

[0061] The lower engaging member 43 overlaps with at least one of the lower frame member 41 and the lower pressing member 42 in a front view. The lower engaging member 43 overlaps with at least one of the first lower surface material support portion 412 and the second lower surface material support portion 422 in a front view. In this embodiment, the lower engaging member 43 overlaps with both the first lower surface material support portion 412 and the second lower surface material support portion 422 in a front view. In this embodiment, the lower engaging member 43 overlaps with the first rising portion 413 and the second rising portion 423 in a front view. The lower engaging member 43 is located between the first lower surface material support portion 412 and the first rising portion 413 in the vertical direction.

[0062] The lower frame portion 40 has a bottom decorative material 47. The bottom decorative material 47 covers at least a part of the lower frame member 41 and the lower pressing member 42, thereby concealing at least a part of the lower frame member 41 and the lower pressing member 42. The bottom decorative material 47 overlaps at least a part of the lower frame member 41 and the lower pressing member 42 in the vertical direction. The bottom decorative material 47 of this embodiment is arranged so as to overlap the end of the lower frame member 41 and the lower pressing member 42 on the second space S2 side in the vertical direction. The bottom decorative material 47 is configured to cover the part of the lower frame member 41 and the lower pressing member 42 that is located closer to the second space S2 side than the surface material 20 in the vertical direction. The bottom decorative material 47 is made of, for example, resin, wood, etc. The bottom decorative material 47 is arranged so as to contact the floor 1. The bottom decorative material 47 may be fixed to at least one of the lower frame member 41 and the lower pressing member 42 by, for example, screws, adhesives, etc.

[0063] <Operation of the embodiment> A first effect of this embodiment will be described. In the upper frame portion 30 of the handrail 10, the first upper surface material support portion 312 and the second upper surface material support portion 322 are fastened by the upper fastening members 33 to clamp the face material 20. When constructing the handrail 10, the face material 20 can be attached to the upper frame portion 30 by tightening the upper fastening members 33. Also, in cases such as when replacing the face material 20 after installing the handrail 10, the face material 20 can be removed from the upper frame portion 30 by loosening the upper fastening members 33. In the handrail 10, the face material 20 can be easily attached to and removed from the upper frame portion 30.

[0064] A second effect of this embodiment will be described. In conventional handrails, the surface material may be fixed to the floor by a sealant. When using a sealant, it is necessary to provide an opening in the floor for inserting the surface material, fill the opening with the sealant, and wait until the sealant hardens, which requires a lot of work to handle the sealant. In addition, construction management may become complicated due to schedule adjustments of craftsmen who handle the sealant. In the handrail 10, the surface material 20 is fixed by clamping the upper end 22 by the upper frame portion 30 and the lower end 23 by the lower frame portion 40, so that the handrail 10 does not require the work of handling such a sealant. Furthermore, the handrail 10 can suppress the complication of construction management due to schedule adjustments of craftsmen when constructing the handrail 10.

[0065] Furthermore, when a sealing material is used, the effort of cutting out the sealing material is required when replacing the face material 20. Because the upper hold-down member 32 and the lower hold-down member 42 are positioned offset from the support posts 12, in the handrail 10, the face material 20 can be removed by loosening the upper fastening member 33 and the lower engaging member 43. In the handrail 10, a new face material 20 can be attached by tightening the upper fastening member 33 and the lower engaging member 43, leaving the support posts 12, coping 36, etc. in place. Because the face material 20 can be easily removed and attached in the handrail 10, replacing the face material 20 is easier than when a sealing material is used.

[0066] A third function of this embodiment will be described. In the handrail 10, the upper fastening member 33 overlaps with the first upper surface material support portion 312 and the second upper surface material support portion 322 in the front view. In addition, the lower engaging member 43 overlaps with the first lower surface material support portion 412 and the second lower surface material support portion 422 in the front view. In the handrail 10, the upper fastening member 33 and the lower engaging member 43 can be configured so as to be inconspicuous when viewed from the front. Furthermore, in the front view, the gaps between the lateral ends 21 of the adjacent panel materials 20 overlap the support pole 12, making the gaps between the lateral ends 21 less noticeable, so that the panel materials 20 located on both sides of a certain support pole 12 appear to be connected in the front view. In this way, the handrail 10 appears to use large panel materials 20, so the handrail 10 can have a simple and beautiful configuration.

[0067] <Effects of the embodiment> (1) The handrail 10 comprises a panel 20 and an upper frame portion 30. The upper frame portion 30 clamps the upper end portion 22 of the panel 20. The upper frame portion 30 has a first upper surface material support portion 312, a second upper surface material support portion 322, and an upper fastening member 33. The first upper surface material support portion 312 is provided so as to follow the first surface 20A of the panel 20. The second upper surface material support portion 322 is provided so as to follow the second surface 20B of the panel 20. The upper fastening member 33 fastens the first upper surface material support portion 312 and the second upper surface material support portion 322 above the upper end portion 22 so as to clamp the upper end portion 22 between the first upper surface material support portion 312 and the second upper surface material support portion 322.

[0068] According to this configuration, the face material 20 is fixed to the upper frame portion 30 by the first upper face material support portion 312 and the second upper face material support portion 322 sandwiching the face material 20 with the upper fastening members 33, and therefore the face material 20 can be removed by loosening the upper fastening members 33. Since the face material 20 can be conveniently replaced by removing it in this way, the maintainability of the handrail 10 can be improved.

[0069] (2) The upper fastening member 33 overlaps with at least one of the first upper surface material support portion 312 and the second upper surface material support portion 322 when viewed from the front.

[0070] According to this configuration, the upper fastening member 33 overlaps with at least one of the first upper surface material support portion 312 and the second upper surface material support portion 322 when viewed from the front, making the upper fastening member 33 less noticeable. This is expected to improve the design of the handrail 10.

[0071] (3) The second upper surface material support portion 322 overlaps with the first upper surface material support portion 312 in a front view, and is positioned away from the support pillar 12 in the direction in which the upper frame portion 30 extends.

[0072] According to this configuration, the second upper surface material supporting portion 322 is positioned offset from the support column 12 in a front view, so that the upper fastening member 33 can be positioned so as not to interfere with the support column 12. Therefore, the fastening condition of the upper fastening member 33 to the first upper surface material supporting portion 312 and the second upper surface material supporting portion 322 can be suitably adjusted so that the upper frame portion 30 can clamp the upper end portion 22 of the face material 20.

[0073] (4) The upper frame portion 30 has an upper frame member 31, an upper pressing member 32, and an upper decorative material 37. The upper decorative material 37 overlaps at least a portion of the upper frame member 31 and the upper pressing member 32 in the vertical direction.

[0074] According to this configuration, at least a portion of the upper frame member 31 and the upper pressure member 32 are concealed by the upper decorative material 37, which is expected to improve the design of the handrail 10.

[0075] (5) The handrail 10 has a lower frame portion 40. The lower frame portion 40 clamps the lower end portion 23 of the panel 20. The lower frame portion 40 has a lower frame member 41, a lower holding member 42, and a lower engagement member 43. The lower frame member 41 has a first lower surface material support portion 412. The first lower surface material support portion 412 is provided so as to fit along the first surface 20A. The lower holding member 42 has a second lower surface material support portion 422. The second lower surface material support portion 422 is provided so as to fit along the second surface 20B. The lower engagement member 43 engages with one of the lower frame member 41 and the lower holding member 42 so as to clamp the lower end portion 23 between the first lower surface material support portion 412 and the second lower surface material support portion 422. The lower engagement member 43 overlaps with at least one of the first lower surface material support portion 412 and the second lower surface material support portion 422 when viewed from the front.

[0076] According to this configuration, the lower engaging member 43 can support the panel material 20 so that the first undersurface material supporting portion 412 and the second undersurface material supporting portion 422 sandwich the panel material 20. Because the lower engaging member 43 overlaps with at least one of the first undersurface material supporting portion 412 and the second undersurface material supporting portion 422 when viewed from the front, the lower engaging member 43 becomes less noticeable. This is expected to improve the design of the handrail 10.

[0077] (6) The second undersurface material support portion 422 overlaps with the first undersurface material support portion 412 in a front view, and is positioned away from the support pillar 12 in the direction in which the lower frame portion 40 extends.

[0078] According to this configuration, the second undersurface material supporting portion 422 is positioned offset from the support pillar 12 when viewed from the front, so that the second undersurface material supporting portion 422 can be positioned so as not to interfere with the support pillar 12.

[0079] (7) The lower frame portion 40 has a bottom decorative material 47. The bottom decorative material 47 overlaps at least a portion of the lower frame member 41 and the lower presser member 42 in the up-down direction.

[0080] According to this configuration, at least a portion of the lower frame member 41 and the lower pressure member 42 are concealed by the bottom decorative material 47, which is expected to improve the design of the handrail 10.

[0081] (8) The handrail 10 comprises a support post 12 and two adjacent panel members 20. The two panel members 20 are arranged so that a gap is provided between the lateral end portion 21 of one panel member 20 and the lateral end portion 21 of the other panel member 20. The two panel members 20 are arranged so that the gap between the lateral end portion 21 of one panel member 20 and the lateral end portion 21 of the other panel member 20 overlaps with the support post 12 in a front view.

[0082] With this configuration, the gap between the two panel materials 20 overlaps with the support pillar 12 when viewed from the front, making the gap less noticeable when viewed from the front. Since the gap is not noticeable, the two panel materials 20 look connected, which is expected to improve the design of the handrail 10.

[0083] <Modification> The above-mentioned embodiment is an example of the form that the handrail can take, and is not intended to limit the form. The handrail can take a form different from the form exemplified in the above-mentioned embodiment. Such an example is a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment.
