Summary of the Invention

Problems to be Solved by the Invention

[0004] However, such a handrail having a cross bar has a complicated structure, so construction takes time. In particular, in a handrail having a projecting portion on the outdoor side of the support column, when the projecting portion has a cross bar, work from the indoor side is difficult, so the problem of workability becomes prominent.

[0005] In view of such circumstances, the present invention provides a handrail having a projecting portion provided on the outdoor side of a support column, the projecting portion having a cross bar, and having good workability with respect to the projecting portion.

Means for Solving the Problems

[0006] The handrail of the present invention comprises a support post and an overhang provided on the outdoor side of the support post, the overhang having one or more intermediate rails provided at an intermediate position in the vertical direction and panel bodies arranged above and below the intermediate rails, at least one of the panel bodies being a plate material, at least one of the intermediate rails having an intermediate rail body, a trim, and a groove formed by the intermediate rail body and the trim, into which the end of the plate material is inserted, and the trim is provided on the indoor side of the intermediate rail, at least one of the upper and lower sides. The panel bodies include glass panel bodies having glass plate materials, resin panel bodies having resin plate materials, louvers, and lattice panel bodies having vertical lattices or grid lattices.

[0007] Furthermore, the present invention may also be such that the trim is provided on only one of the upper or lower sides of the intermediate rail, and one of a plurality of types of trim members corresponding to the shape of the panel body provided on the other upper or lower side of the intermediate rail is selected and attached.

[0008] Furthermore, in the present invention, the trim may be provided both above and below the middle rail. [Effects of the Invention]

[0009] According to the present invention, since a trim strip is provided on the indoor side of the intermediate rail, the installation of the boards can be performed from the indoor side. In other words, the assembly of the cantilevered section, which is positioned at a predetermined location on the outdoor side, can be performed from the indoor side, resulting in good work efficiency. Maintenance such as replacing the boards after installation is also easy.

[0010] Furthermore, if one of several types of jointing members can be selected and attached to the middle rail, it can accommodate panel bodies of various shapes. [Brief explanation of the drawing]

[0012] The specific details of the handrail of the present invention will be described below. This handrail can be installed and used in various locations, but here we will show an embodiment in which it is installed on the balcony of an apartment building for the purpose of preventing falls. In the following, the depth direction of the handrail is defined as the front-to-back direction, where the outdoor side is the front and the indoor side is the rear. Also, the width direction (horizontal direction) of the handrail is defined as the left-to-right direction.

[0013] Based on FIGS. 1 to 7, the first embodiment will be described. As shown in FIGS. 1 and 2, this handrail is erected on the body B and includes a plurality of columns 200 arranged at intervals left and right, and a take-out portion 100 provided on the front side of the columns 200. The take-out portion 100 partitions the outdoor side and the indoor side. The columns 200 support the take-out portion 100.

[0014] The column 200 is made of a hollow profile with a substantially rectangular cross-section. The column 200 is made of aluminum. Inside the column 200, a core material 201 extending vertically is inserted. At the lower end of the core material 201, a split bolt 206 protruding downward is attached, and the split bolt 206 is inserted into a lower hole formed in the body B and fixed with resin. And the column 200 is fixed to the core material 201 by screwing. As shown in FIG. 6, on the front surface of the column 200, fins 202 protruding toward the front side are formed. Details of the fins 202 will be described later. However, the columns 200 located at both left and right ends do not have the fins 202.

[0015] The take-out portion 100 has an upper rail 2 and a lower rail 3, a middle rail 1 provided between the upper rail 2 and the lower rail 3, panel bodies 4 arranged above and below the middle rail 1 and side by side left and right, a vertical frame 6 provided between the panel bodies 4 arranged side by side left and right at the intermediate position in the left-right direction of the take-out portion 100, and end vertical members 7 provided at the left-right direction ends of the take-out portion 100. The upper rail 2, the lower rail 3 and the middle rail 1 extend in the left-right direction. The vertical frame 6 and the end vertical members 7 extend in the vertical direction. The vertical frame 6 and the end vertical members 7 are divided vertically and provided between the upper rail 2 and the middle rail 1 and between the middle rail 1 and the lower rail 3. The middle rail 1, the upper rail 2, the lower rail 3, the vertical frame 6 and the end vertical members 7 are all made of aluminum extrusion profiles.

[0016] Each of the panel bodies 4 is a glass plate 41. The upper plate 41 is accommodated between the upper rail 2 and the middle rail 1. The lower plate 41 is accommodated between the middle rail 1 and the lower rail 3.

[0017] The intermediate rail 1 extends to the left and right, and will be described based on its cross-sectional shape when viewed from the left and right directions. As shown in Figure 3, the intermediate rail 1 has an intermediate rail body 11, a trim piece 12, a groove (upper groove 13) formed by the intermediate rail body 11 and the trim piece 12, and a cover plate member 14. The trim piece 12 is provided only on the upper side of the intermediate rail 1. The intermediate rail body 11 has a roughly U-shaped front projection 111 located on the front side in cross-section and opening downwards, a rear projection 112 extending towards the rear from the lower end of the rear wall surface of the front projection 111, and a hanging portion 113 extending downwards from the rear end of the rear projection 112. The front wall surface of the front projection 111 is longer than the rear wall surface, and the height position of the lower end of the front wall surface is the same as the height position of the lower end of the hanging portion 113. 121 12 The rear surface of the rear engaging portion 122 has a shape that protrudes further to the rear as it goes downwards. The trim piece 12 is attached to the main body of the middle rail 11, and the two become one. That is, the front engaging portion 121 of the trim piece 12 is inserted into the front receiving portion 114 of the main body of the middle rail 11, and the rear engaging portion 122 of the trim piece 12 engages with the rear receiving portion 115 of the main body of the middle rail 11. An upper groove portion 13 that opens upwards is formed between the front protrusion 111 and the trim piece 12. The cover plate member 14 is attached so as to close the lower surface of the main body of the middle rail 11 (between the lower end of the front wall surface of the front protrusion 111 and the lower end of the hanging portion 113), and a lower groove portion 15 that opens downwards is formed in the center in the front-to-back direction. An airtight material 151 is attached to the front wall surface of the lower groove portion 15. Engaging claws 141 that protrude upwards are formed at the front end and rear end of the cover plate member 14.The engaging claws 141 are tapered upwards and have a barb that protrudes outwards in the front-rear direction. The fascia member 14 is attached to the main body 11, and the two become one. That is, the front and rear engaging claws 141 of the fascia member 14 engage with the engaging projections 116 of the main body 11. In this way, the main body 11, the trim 12, and the fascia member 14 are integrated to form the main body 11, which is roughly H-shaped. The lower end of the upper plate material 41 fits into the upper groove 13, and the upper end of the lower plate material 41 fits into the lower groove 15. Within the upper groove 13, the front surface of the plate material 41 abuts against the airtight material 131, and the gap between the rear surface of the plate material 41 and the rear wall surface of the upper groove 13 is sealed with the sealing material 132. Within the lower groove 15, the front surface of the plate 41 abuts against the airtight seal 151, and the gap between the rear surface of the plate 41 and the rear wall surface of the lower groove 15 is sealed with the sealant 152.

[0018] The middle rail 1 is attached to the support column 200 by a middle rail bracket 16. As shown in Figure 6, the middle rail bracket 16 is roughly L-shaped when viewed from above. Two middle rail brackets 16 are attached to a single support column 200, sandwiching the column 200 from the left and right. That is, one side of the middle rail bracket 16 extending in the front-to-back direction is fixed to the left and right sides of the support column 200 by screws, and the other side extends outward in the left-to-right direction from the front end of the one side. The other side of the middle rail bracket 16 abuts against the hanging portion 113 of the middle rail 1 from the rear and is fixed by screws. Note that the fins 202 of the support column 200 are cut off in the height range where the middle rail 1 is present.

[0019] The upper rail 2 extends to the left and right, and will be described based on its cross-sectional shape when viewed from the left and right directions. As shown in Figure 4, the upper rail 2 has an upper rail upper member 21 and an upper rail lower member 22. The upper rail upper member 21 is a molded material with a shape that curves upward in cross-section. The upper rail lower member 22 is a molded material with a straight shape that extends front and back in cross-section. An upper rail groove 23 is formed in the front part of the upper rail lower member 22, opening downward. An airtight material 231 is attached to the front wall surface of the upper rail groove 23. The upper rail upper member 21 and the upper rail lower member 22 engage with each other at their front and rear ends and are integrated. The rear part of the upper rail lower member 22 abuts against the upper end surface of the support column 200 from above and is fixed by screwing it in. The front part of the upper rail 2 protrudes forward relative to the support column 200. The upper end of the upper plate material 41 fits into the upper rail groove 23. Within the upper rail groove 23, the front surface of the plate material 41 abuts against the airtight material 231, and the gap between the rear surface of the plate material 41 and the rear wall surface of the upper rail groove 23 is sealed with the sealing material 232.

[0020] The lower rail 3 extends to the left and right, and will be described based on its cross-sectional shape when viewed from the left and right directions. As shown in Figure 5, the lower rail 3 has a lower rail body 31, a trim piece 32, and a lower rail groove 33 formed by the lower rail body 31 and the trim piece 32. The lower rail body 31 has a shape similar to the middle rail body 11, and like the middle rail body 11, it has a front projection 311, a rear extension 312, a hanging portion 313, a front receiving portion 314, and a rear receiving portion 315. However, compared to the middle rail body 11, the front wall surface of the front projection 311 and the vertical length of the hanging portion 313 are shorter. An airtight material 331 is attached to the rear surface of the rear wall surface of the front projection 311. The trim piece 32 has the same shape as the trim piece 12 of the middle rail 1 and has a front engaging portion 321 and a rear engaging portion 322. The trim piece 32 is attached to the lower rail body 31, and the two become one unit. A lower rail groove 33 is formed between the front protrusion 311 and the trim 32, opening upwards. In this way, the lower rail 3, formed by the integration of the lower rail body 31 and the trim 32, is roughly concave in shape. The lower end of the lower plate material 41 fits into the lower rail groove 33. Within the lower rail groove 33, the front surface of the plate material 41 abuts against the airtight material 331, and the gap between the rear surface of the plate material 41 and the rear wall surface of the lower rail groove 33 is sealed with sealant 332.

[0021] The lower rail 3 is attached to the support column 200 by a lower rail bracket 34. The lower rail bracket 34 is roughly L-shaped when viewed from the left-right direction. One side of the lower rail bracket 34, which extends vertically, is fixed to the front of the support column 200 by screws, and the other side extends forward from the lower end of the one side. The lower rail bracket 34 is roughly the same width as the support column 200 when viewed from the front-rear direction. A mounting fixture 35, which extends horizontally, is attached to the other side of the lower rail bracket 34. The mounting fixture 35 is wider than the support column 200 when viewed from the front-rear direction. The mounting fixture 35 abuts from above against the upper surface of the other side of the lower rail bracket 34 and is fixed by screws. The lower rail 3 is placed on the other side of the lower rail bracket 34 so as to cover the mounting fixture 35 from above, and is fixed to the mounting fixture 35 by screws.

[0022] The vertical frame 6 extends vertically and will be described based on its cross-sectional shape when viewed from the vertical direction. As shown in Figure 6, the vertical frame 6 is attached to the fin 202 of the support column 200. The vertical frame 6 has a front vertical member 61 located at the front, two rear vertical members 62 located at the rear, and a vertical groove portion 63 formed by the front vertical member 61 and the rear vertical members 62. The fin 202 has a fin body 203, a first engaged portion 204, and a second engaged portion 205. The fin body 203 is a flat plate that protrudes forward from the support column 200 and is formed along the entire vertical length of the support column 200. The first engaged portion 204 is formed on the left and right sides of the middle portion of the fin body 203 in the front-rear direction. The first engaged portion 204 is a triangular projection when viewed from above. The front surface of the first engaged portion 204 is inclined with respect to the left and right surfaces of the fin body 203, and the rear surface of the first engaged portion 204 is perpendicular to the left and right surfaces of the fin body 203. The second engaged portion 205 is formed on the left and right sides of the fin body 203, behind the first engaged portion 204. The second engaged portion 205 protrudes from the fin body 203 to the left and right. The tips of each of the left and right second engaged portions 205 are tapered toward the tip and have a return that protrudes toward the rear. The front vertical member 61 has a front wall portion 611, a recessed wall portion 612, a middle receiving portion 613, and the first engaged portion 614. The front wall portion 611 is located at the very front of the vertical frame 6 and extends to the left and right. Airtight material 631 is attached to the rear surfaces of the left and right tips of the front wall portion 611. The recessed wall portion 612 extends from the left-right center of the front wall portion 611 toward the rear. The intermediate support portion 613 is provided on both the left and right sides of the rear end of the recessed wall portion 612 and is substantially U-shaped, opening toward the front. The first engaging portion 614 is provided on the rear side of the intermediate support portion 613 and is substantially U-shaped, opening toward the rear. The left and right rear ends of the first engaging portion 614 are tapered toward the rear and have a shape with a return that protrudes inward in the left-right direction. The two rear vertical members 62 are positioned on the left and right sides of the fin 202 and the front vertical member 61. The two rear vertical members 62 are symmetrical and each has a rear wall portion 621, a projection 622, a recessed wall portion 623, and a second engaging portion 624. The rear wall portion 621 is located behind the front wall portion 611 and extends to the left and right. The protrusion 622 projects outward from the inner left-right end of the rear wall portion 621. The recessed wall portion 623 extends outward from the left-right center of the rear wall portion 621.The second engaging portion 624 extends inward in the left-right direction from the rear end of the recessed wall portion 623. The tip of the second engaging portion 624 is tapered toward the tip and has a return that protrudes toward the front. The vertical frame 6 is provided between the upper rail 2 and the middle rail 1 and between the middle rail 1 and the lower rail 3. The front vertical member 61 is attached to the fin 202. The front portion of the fin body 203 is housed inside the first engaging portion 614, and the first engaging portion 614 engages with the first engaged portion 204. Then, two rear vertical members 62 are attached to the fin 202 and the front vertical member 61. The projection 622 is inserted into the middle receiving portion 613, and the second engaging portion 624 engages with the second engaged portion 205 from the rear. At this time, the front wall portion 611 of the front vertical member 61 and the rear wall portion 621 of the rear vertical member 62 face each other with a gap between them, and a vertical groove portion 63 is formed between them. The left and right ends of the plate material 41 fit into the vertical groove portion 63. At this time, the front surface of the plate material 41 abuts against the airtight material 631, and the gap between the rear surface of the plate material 41 and the rear wall portion 621 is sealed with the sealing material 632.

[0023] The end vertical member 7 extends vertically and will be described based on its cross-sectional shape when viewed from the vertical direction. The description will also be based on the end vertical member 7 provided at the right end of the overhang 100 (the end vertical member 7 provided at the left end has a symmetrical shape). As shown in Figure 7, the end vertical member 7 has an end vertical member body 71, a trim 72, and an end groove 73 formed by the end vertical member body 71 and the trim 72. The end vertical member body 71 has a front wall portion 711 that extends horizontally and a rear extension portion 712 that extends from the right end of the front wall portion 711 toward the rear. A roughly U-shaped front support portion 713 that opens toward the rear is formed at the center of the front-to-back direction on the left side of the rear extension portion 712. A rear support portion 714 that protrudes toward the left is formed at the rear end of the rear extension portion 712. The front surface of the rear support portion 714 protrudes toward the front as it goes toward the left. An airtight seal 731 is attached to the rear surface of the front wall portion 711. The trim piece 72 is roughly U-shaped, opening to the right. A front engaging portion 721 that protrudes forward is formed at the right end of the front wall surface of the trim piece 72. A rear engaging portion 722 that protrudes forward and then bends to protrude to the right is formed at the right end of the rear wall surface of the trim piece 72. The rear surface of the rear engaging portion 722 has a shape that protrudes further to the rear as it goes to the right. The end vertical members 7 are provided between the upper rail 2 and the middle rail 1, and between the middle rail 1 and the lower rail 3. The upper end vertical member body 71 has its upper and lower ends screwed to the ends of the upper rail 2 and the middle rail 1, respectively. The lower end vertical member body 71 has its upper and lower ends screwed to the ends of the middle rail 1 and the lower rail 3, respectively. The trim piece 72 is then attached to the end vertical member body 71, and the two become one unit. Specifically, the front engaging portion 721 of the trim strip 72 is inserted into the front receiving portion 713 of the end vertical member body 71, and the rear engaging portion 722 of the trim strip 72 engages with the rear receiving portion 714 of the end vertical member body 71. An end groove portion 73 opening to the left is formed between the front wall portion 711 and the trim strip 72. The right end of the rightmost plate material 41 fits into the end groove portion 73. Within the end groove portion 73, the front surface of the plate material 41 abuts against the airtight material 731, and the gap between the rear surface of the plate material 41 and the rear wall surface of the end groove portion 73 is sealed with sealant 732.

[0024] The right-side end vertical member 7 is located to the right of the rightmost support column 200. On the rightmost support column 200, the middle rail bracket 16 is attached only to the left side of the support column 200. The bottom rail bracket 34 is attached in the same way as on the other support columns 200, but the mounting fixture 35 is shorter in width than those on the other support columns 200. The same applies to the left-side end vertical member 7.

[0025] Next, I will explain the installation procedure for this handrail. (1) Erecting of support columns 200 A pilot hole is formed in the frame B. A threaded rod 206 is screwed into the lower end of the core material 201. Next, resin is poured into the pilot hole. Then, the threaded rod 206 protruding from the core material 201 is inserted into the pilot hole. The core material 201 is then held in place and the resin is allowed to harden. This fixes the core material 201 to the frame B. Next, the support column 200 is placed over the outside of the core material 201. Then, screws are driven into the support column 200 from the rear, and the support column 200 and the core material 201 are screwed together and fixed in place. (2) Installation of the lower rail 3 The lower rail bracket 34 is attached to the front of the support column 200. Next, the mounting fixture 35 is attached to the lower rail bracket 34. Then, the lower rail body 31 is attached to the mounting fixture 35. (3) Installation of the middle rail 1 The intermediate support brackets 16 are attached to the left and right sides of the support column 200. Next, the intermediate support body 11 is attached to the intermediate support brackets 16. Next, the cover plate member 14 is attached to the intermediate support body 11. (4) Installation of upper rail 2 The lower upper rail member 22 is attached to the upper end surface of the support column 200. Next, the upper upper rail member 21 is attached to the lower upper rail member 22. (5) Installation of vertical frame 6 and end vertical members 7 The front vertical member 61 is attached to the fin 202 of the support column 200. In addition, the end vertical member body 71 is attached to the left and right ends of the upper rail 2, middle rail 1, and lower rail 3. (6) Installation of the upper plate 41 The board 41 is tilted forward, and its upper end is inserted into the upper rail groove 23 of the upper rail 2 from the rear and below. Then, the board 41 is rotated around its upper edge as an axis, and its lower end is brought into contact with the airtight material 131 of the middle rail 1. Then, the trim strip 12 is attached to the middle rail body 11. As a result, the lower end of the board 41 fits into the upper groove 13. Furthermore, for the board 41 in the middle section in the left-right direction, the rear vertical members 62 are attached to the left and right front vertical members 61. As a result, the left and right ends of the board 41 fit into the vertical grooves 63. Also, for the board 41 at the left-right ends, the rear vertical member 62 is attached to one of the left or right front vertical members 61, and the trim strip 72 is attached to the other left or right end vertical member body 71. As a result, one left or right end of the board fits into the vertical groove 63, and the other end fits into the end groove 73. Then, sealants 132, 232, 632, and 732 are injected into the gaps between the rear surfaces of the top, bottom, left, and right ends of the plate material 41 and the walls of each groove. The plate material 41 is fixed in place as the sealants 132, 232, 632, and 732 harden. (7) Installation of the lower plate 41 The board 41 is tilted forward, and its upper end is inserted into the lower groove 15 of the middle rail 1 from the rear and below. Then, the board 41 is rotated around its upper edge as an axis, and its lower end is brought into contact with the airtight seal 331 of the lower rail 3. Finally, the trim 32 is attached to the lower rail body 31. This causes the lower end of the board 41 to fit into the lower rail groove 33. The left and right fitting of the board 41 and its fixing with the sealing materials 152, 332, 632, and 732 are the same as the upper part.

[0026] Note that the order of some parts of the above construction procedure may be changed. For example, the upper member 21 of the upper rail may be attached to the lower member 22 of the upper rail after the board material 41 has been attached. Also, the trim pieces 12 and 32 of the middle rail 1 and bottom rail 3 may be attached after the trim pieces 72 of the rear vertical member 62 and the end vertical member 7 have been attached.

[0027] With the handrail of the first embodiment configured in this way, since the trim strip 12 is provided on the indoor side of the middle rail 1, the installation of the board material 41 can be done from the indoor side. In other words, the cantilevered section 100, which is positioned at a predetermined location on the outdoor side, can be assembled from the indoor side, resulting in good workability. Maintenance such as replacing the board material 41 after installation is also easy.

[0028] Next, the handrail of the second embodiment will be described based on Figures 8 to 11. Compared to the first embodiment, the handrail of the second embodiment differs in the shape of the lower panel body 4 and the middle rail 1. It does not have a bottom rail. As shown in Figure 8, the lower panel body 4 is a louver 43.

[0029] The louver 43 has multiple lattice members 44, an auxiliary vertical frame 45 provided in the middle of the cantilever 100 in the left-right direction, and end covers 46 provided at the left-right ends of the cantilever 100. The lattice members 44, auxiliary vertical frame 45, and end covers 46 are all made of extruded aluminum. As shown in Figure 9, the lattice member 44 extends left and right and has a lattice member body 441 and extension pieces 442. The lattice member body 441 has a parallelogram cross-section, with a front wall surface and a rear wall surface that extend vertically, with the front wall surface being on the upper side. The extension pieces 442 extend downward from the lower end of the lattice member body 441 (the lower end of the rear wall surface). As shown in Figure 10, the auxiliary vertical frame 45 is attached to the support column 200. The auxiliary vertical frame 45 extends vertically. Each auxiliary vertical frame 45 has a visible surface portion 452 extending to the left and right, a front visible surface portion 451 extending forward from one end of the visible surface portion 452, and a rear visible surface portion 453 extending backward from the other end of the visible surface portion 452. Two auxiliary vertical frames 45 are attached to a single support column 200, sandwiching the column 200 from the left and right. That is, the visible surface portions 452 of the left and right auxiliary vertical frames 45 abut against the front of the column 200, the rear visible surface portions 453 abut against the left and right sides of the column, and the front visible surface portion 451 protrudes forward from the left-right center of the column 200. The rear visible surface portion 453 is fixed to the column 200 by screws. The end faces of the lattice members 44 then abut against the front visible surface portion 451 from the left and right directions and are fixed by screws. In the height range where the auxiliary vertical frame 45 exists, the fins 202 of the support column 200 are removed. As shown in Figure 11, the end cover 46 is a flat plate that extends vertically. The end cover 46 abuts against the left and right end faces of the lattice material 44 and is fixed by screwing it in. At the right end of the louver 43, the right end cover 46 is located to the right of the rightmost support column 200. At the rightmost support column 200, an angle material 47 is attached in place of the auxiliary vertical frame 45. The angle material 47 extends vertically and has a roughly L-shaped cross-section. One side of the angle material 47 that extends in the front-to-back direction is fixed by screwing it to the left face of the support column 200, and the other side extends to the right from the front end of the one side. The other side of the angle material 47 abuts against the rear face of the lattice material body 441 from the rear and is fixed by screwing it in. The same applies to the left end of the louver 43.

[0030] Furthermore, as shown in Figure 9, in the middle rail 1, the middle rail body 11 and the trim 12 are the same as in the first embodiment, but the joint plate member 14a is different from that of the first embodiment. The joint plate member 14a in the second embodiment is a flat plate that does not have a lower groove.

[0031] The handrail of the second embodiment, configured in this way, provides the same effects and advantages as the first embodiment. In addition, a different cover plate member 14a is selected, corresponding to the fact that the lower panel body 4 is a louver 43, compared to the first embodiment.

[0032] Next, the handrail of the third embodiment will be described based on Figures 12 and 13. Compared to the first embodiment, the handrail of the third embodiment has different shapes for the upper panel body 4, the middle rail 1, and the top rail 2. As shown in Figure 12, the upper panel body 4 is a louver 43.

[0033] The configuration of the louvers 43 is the same as that of the louvers 43 in the second embodiment. However, the number of lattice members 44 may be different.

[0034] Furthermore, as shown in Figure 13, the intermediate rail 1 has the shape of the intermediate rail 1 of the second embodiment inverted vertically. That is, it has an intermediate rail body 11b, a trim piece 12b provided on the lower side of the intermediate rail body 11b, a lower groove portion 13b formed by the intermediate rail body 11b and the trim piece 12b, and a cover plate member 14b that closes the upper surface of the intermediate rail body 11b.

[0035] Furthermore, as shown in Figure 12, in the upper rail 2, the upper member 21 of the upper rail is the same as in the first embodiment, while the lower member 22b of the upper rail is different from that of the first embodiment. In the third embodiment, the lower member 22b of the upper rail is a flat plate that does not have an upper rail groove.

[0036] The handrail of the third embodiment, configured in this way, provides the same effects and advantages as the first embodiment. Since it has a trim 12b on the lower side of the middle rail 1 and a trim 32 on the bottom rail 3, the plate material 41 (lower panel body 4) can be attached from either the top or bottom side. The bottom rail 3 may not have a trim. Furthermore, a different cover plate member 14b is selected in correspondence with the upper panel body 4 being a louver 43, compared to the first embodiment.

[0037] Next, the handrail of the fourth embodiment will be described based on Figure 14. The handrail of the fourth embodiment differs from that of the first embodiment in the shape of the middle rail 1. As shown in Figure 14, the middle rail 1 has two trim pieces 12c at the top and bottom.

[0038] The fourth embodiment of the intermediate rail 1 includes an intermediate rail body 11c, two upper and lower trim pieces 12c, and an upper groove portion 13c and a lower groove portion 15c formed by the intermediate rail body 11c and the trim pieces 12c. The intermediate rail body 11c has a vertically symmetrical shape. The intermediate rail body 11c has a roughly U-shaped front upper protrusion 111c located on the front and upper side in cross-section and opening downwards, a roughly U-shaped front lower protrusion 117c located on the front and lower side and opening upwards, a rear extension portion 112c extending backwards from the lower end of the rear wall surface of the front upper protrusion 111c and the upper end of the rear wall surface of the front lower protrusion 117c, respectively, and a hanging portion 113c connecting the rear ends of the upper and lower rear extension portions 112c. The front wall surface of the front upper protrusion 111c and the front wall surface of the front lower protrusion 117c are connected and continuous vertically. Similar to the first embodiment, a front support portion 114c and a rear support portion 115c are formed on the upper and lower rear extension portions 112c. The trim piece 12c is the same as the trim piece 12 of the first embodiment. The two trim pieces 12c are attached to the middle rail body 11c and become one unit. An upper groove portion 13c opening upward is formed between the front upper protrusion portion 111c and the upper trim piece 12c. A lower groove portion 15c opening downward is formed between the front lower protrusion portion 117c and the lower trim piece 12c. In this way, the middle rail 1 formed by the middle rail body 11c and the two trim pieces 12c is approximately H-shaped. The lower end of the upper plate material 41 fits into the upper groove portion 13c, and the upper end of the lower plate material 41 fits into the lower groove portion 15c.

[0039] The handrail of the fourth embodiment, configured in this way, provides the same effects and advantages as the first embodiment. Since it has a trim 12c on the lower side of the middle rail 1 and a trim 32 on the bottom rail 3, the lower board material 41 can be attached from either the top or bottom side. Note that the bottom rail 3 may not have a trim.

[0040] The present invention is not limited to the embodiments described above, and within the scope of the invention, the shape and structure of each part can be appropriately modified considering the conditions of the installation location and design considerations. For example, the panel body may be made of any material, such as boards or louvers, as well as vertical lattices or grid patterns. It is desirable that multiple types of grout members corresponding to these various shapes of panel bodies be provided, and that one of them be selected and attached to the middle rail. Furthermore, the shapes of the support columns, upper rail, and lower rail may be any shape. It may even be possible to have no upper or lower rail. [Explanation of Symbols]
