[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings denote parts with the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. Hereinafter, a reference numeral with an A attached thereto indicates a member of Example A. For example, ledge 3A indicates a ledge of Example A. Figure 1 is a plan view of a handrail 9 having a corner portion 95 of Example A at an inside corner and a corner portion 95 of Example B at an outside corner. Figure 1 shows the handrail 9 installed on a balcony, with outside and inside corner portions 95 following the shape of the balcony. The handrail 9 is supported by posts 94, and has multiple panels 1 fitted into it. A coping 91 is attached to the top of the handrail 9. In the following description, the terms "other side" and "one side" will be used, but in this specification, the outer side will be referred to as the "other side" and the inner side will be referred to as the "one side." In the drawing, the corner portion 95 at the inside corner is Example A, and the corner portion 95 at the outside corner is Example B.

[0010] [Example A] Example A is an example of a corner portion 95 arranged at an inside corner. Example A is an example of claim 1. Figure 2 is an explanatory diagram of the structure of the handrail 9. Figure 2(A) is an explanatory diagram of fitting a panel 1 into an upper rail 92 and a lower rail 93 of the handrail 9. The handrail 9 has an upper rail 92 and a lower rail 93 supported by supports 94. A coping 91 is attached to the top of the upper rail 92. The panel 1 is attached between the upper rail 92 and the lower rail 93 with a kendon. Figure 2(B) is an explanatory diagram of the state in which the panel 1 has been attached to the handrail 9.

[0011] The corner portion 95 has a different structure for an inside corner and an outside corner, and the structure will be described later. Example A is an example of a corner portion 95 for an inside corner. The corner portion 95 does not have a support pillar 94 arranged therein.

[0012] (corner part) Figure 3 is an explanatory diagram of a corner portion 95 of Example A. Figure 3(A) is a plan view of the corner portion 95, which is an inside corner, Figure 3(B) is a plan view of the batten 3A, and Figure 3(C) is a plan view of the vertical corner frame 2A. For the sake of clarity, the corner portion 95 in Figure 3 does not include the fascia 91, upper rail 92, and lower rail 93. The corner portion 95 is concealed by covering its upper portion with the fascia 91, as shown in Figure 1. The batten 3A in Figure 3(B) is attached to the vertical corner frame 2A in Figure 3(C), allowing for easy assembly as shown in Figure 3(A). The construction process will be described later. Depending on the order in which the panels 1 are attached, there are pre-attached panels 11 that are attached first to the vertical corner frame 2A, and retrofitted panels 12 that are attached later. As shown in Figure 3(A), when the batten 3A is fitted into the vertical corner frame 2A to which the pre-attached panel 11 is attached, and before the retrofitted panel 12 is attached, the panel receiving groove of the retrofitted panel 12 is open, allowing the fixing screw 96 to be tightened with a tool. The worker can then insert the retrofitted panel 12 into the panel receiving groove formed by the batten 3A and the vertical corner frame 2A.

[0013] (Burst) In Example A, one side of the panel 1 is the inner balcony side, and the other side is the outer side. Fig. 3(B) is a plan view of the batten 3A. The flaps 3A have a flaps other side facing surface portion 3A1 that faces the other side surface 113 of the front-attached panel, and a flaps other side facing surface portion 3A1 that faces the other side surface 123 of the rear-attached panel. As shown in the figure, the front-attached panel 11 side and the rear-attached panel 12 side have the same structure. The batten 3A also has a batten projection piece 3A2 that faces the projected surface 122 of the retrofit panel 12. The batten 3A is attached by being pressed in from the other side. At that time, the batten projection piece 3A2 is attached so as to overlap with the projected surface 2A2 of the vertical corner frame 2A, as shown in Figure 3(A). As mentioned above, a fixing screw 96 is driven into this overlapping portion, and the batten 3A and the vertical corner frame 2A are integrated. The tip of the edge projection piece 3A2 is an engaging portion 3A21, which engages with the groove-shaped engaged portion 2A3 of the vertical corner frame 2A. (The portion shown as "3A21 (2A3)" in Figure 3(A))

[0014] (vertical corner frame) The vertical corner frame 2A has a shape symmetrical about the center line shown in Figure 3(C). One side of the pre-attached panel 11 and one side of the post-attached panel 12 have identically shaped facing surfaces 2A1 on one side of the vertical corner frame. The vertical corner frame 2A also has a facing surface 2A1 on one side of the vertical corner frame 2A on the side of one side 111 of the pre-attached panel. The vertical corner frame 2A also has a facing surface 2A1 on one side of the post-attached panel 12 on the side of one side 121 of the post-attached panel.

[0015] (Can be installed upside down) In Example A, the pre-attached panel 11 and the post-attached panel 12 are attached in the order shown in Figure 3(A), but this order can be reversed. The corner vertical frame 2A is symmetrical about the center line regardless of whether the order of the pre-attached panel 11 and the post-attached panel 12 is changed, and the position does not change regardless of which panel 1 is attached first or last. Figure 4 is an explanatory diagram of the case where the attachment order of the panels 1 in Example A is changed. If the attachment order of the panels 1 is changed, the batten 3A can be reoriented and attached upside down. In this way, Example A does not have a fixed attachment order for the panels 1 as in the past, and it is possible for workers to decide the order of the panels 1 to make installation easier.

[0016] (Construction procedure for Example A) Figure 5 is an explanatory diagram of the construction procedure for Example A. In step 1, the corner vertical frame 2A, support posts 94, upper crosspiece 92, and lower crosspiece 93 are installed in advance. The worker installs the pre-attached panel 11 with a push-in mechanism in the direction of the arrow 1 in the figure. The worker then moves the panel to a position slightly away from the panel insertion groove and abuts it against the visible surface of the adjacent panel 1 (not shown) in the direction of the arrow 2, sealing the gap between the pre-attached panel 11 and the panel insertion groove. The seal may be either a wet seal or a dry seal, and Example A uses a bead, which is a dry seal. The following Examples B and C are similar, and use a bead as the seal.

[0017] In step 2, the worker presses the batten 3A in the direction of the arrow 1 in the figure and moves it in the direction of the arrow 2 in the figure. As a result, the batten projecting piece portion 3A2 overlaps with the projecting surface portion 2A2 of the vertical corner frame 2A as shown in Figure 3(A). Then, a fixing screw 96 is driven into this overlapping portion in the direction of the arrow 3 in the figure, and the batten 3A and the vertical corner frame 2A are integrated.

[0018] In step 3, the worker inserts the retrofit panel 12 into the panel-swallowing groove formed by the exposed surface portion 2A1 on one side of the corner vertical frame and the exposed surface portion 3A1 on the other side of the batten, and seals it.

[0019] In step 4, the worker fits the add-on panel 12 onto the upper crosspiece 92 and lower crosspiece 93 that have been installed in advance.

[0020] As described above, Example A can be installed regardless of the mounting orientation of the panel 1, improving work efficiency and making it easy to use. In addition, the same materials can be used even if the mounting orientation of the panel 1 is changed, making it inexpensive and easy to use.

[0021] [Example B] Example B is an example of claim 2. Hereinafter, a reference numeral with B attached thereto indicates a member of Example B. For example, ledge 3B indicates a ledge of Example B. Example B is an example of a corner portion 95 arranged at a protruding corner. Figure 6 is an explanatory diagram of the structure of the handrail 9 of Example B. Figure 6 illustrates a corner portion 95 of the protruding corner of the handrail 9 installed on a balcony. At first glance, Figure 6 appears to have one side and the other side reversed from Figure 3, but this is because the inside of the balcony is defined as one side and the outside as the other side, as defined in Figure 1.

[0022] (vertical corner frame) Figure 6(A) is a cross-sectional view of a corner portion 95 of Example B at an outside corner. As shown in Figure 6(A), there is a pre-attached panel one side surface 111 and a pre-attached panel other side surface 113, and there is also a post-attached panel one side surface 121 and a post-attached panel other side surface 123. The corner vertical frame 2B does not contact the pre-attached panel one side surface 111 and the post-attached panel one side surface 121. The corner vertical frame 2B has a pair of one-side facing surface portions 2B1 (Figure 6(B)) that face one side (111-121) of the pre-attached panel 11 and the post-attached panel 12, i.e., the one-side 111 side of the pre-attached panel and the one-side 121 side of the post-attached panel, respectively. Figure 6(D) is an explanatory diagram of the attachment relationship between the vertical corner frame 2B and the batten 3B. As shown in Figures 6(A) and 6(D), the projecting surface portion 2B3 of the vertical corner frame on the retrofit panel 12 side overlaps with the batten extension portion 3B4. The overlapping portion is fixed with a fixing screw 96, and the batten 3B and the vertical corner frame 2B are integrated. Figure 6(B) is a plan view of the vertical corner frame 2B of Example B. As shown in Figure 6(B), the vertical corner frame 2B has two visible surfaces 2B1 on one side of the vertical corner frame, one of which faces the pre-attached panel 11 and the other of which faces the post-attached panel 12 and is attached to the corner portion 95.

[0023] (Burst) Fig. 6(C) is a plan view of the batten 3B of Example B. Fig. 6(D) is an explanatory diagram of the attachment relationship between the corner vertical frame 2B and the batten 3B. The batten 3B has a pair of batten one-side facing surface portions 3B1, a pair of batten other-side facing surface portions 3B2, and a pair of batten expected surface portions 3B6 shown in Fig. 6(C), which face one side (one side of the batten panel 111 and one side of the after-attachment panel 121), the other side (the other side of the batten panel 113 and the other side of the after-attachment panel 123), and the expected surface (the expected surface 114 of the batten panel and the expected surface 122 of the after-attachment panel) of the before-attachment panel 11 and the after-attachment panel 12, respectively. The batten 3B has a pair of batten one-side facing surface portions 3B1 abutting against a pair of vertical corner frame one-side facing surface portions 2B1. On the remaining side of the vertical corner frame 2B, the batten extension portion 3B4 abuts against the vertical corner frame facing surface portion 2B3. As a result, the vertical corner frame 2B is surrounded and abutted on three sides by the batten 3B. The flange 3B also has a hollow portion surrounded by a pair of flange projection surface portions 3B6 and a pair of flange other side projection surface portions 3B2.

[0024] See the center line in Figure 6(D). The corner vertical frame 2B is symmetrical about the center line, so there is no need to change its direction regardless of the front or back of the panel 1. The sash 3B's sash extension 3B4 breaks the symmetry, so if the installation order of the panels 1 is changed, simply turning the sash 3B upside down will change the direction of the sash extension 3B4, allowing for changes in the installation order of the panels 1 to be accommodated.

[0025] (Can be installed upside down) The corner vertical frame 2B is symmetrical about the center line regardless of whether the order of the pre-attached panel 11 and the post-attached panel 12 is changed, and its position does not change regardless of which panel 1 is first or last. Figure 7 is an explanatory diagram of the case where the installation order of the panels 1 in embodiment B is changed. As shown in the figure, even if the order of the panels 1 is changed, the position of the extension 3B4 of the batten 3B changes by changing the direction of the batten 3B, allowing the worker to install the panel 1. In this way, the corner portion 95 of the embodiment B is configured so that the ridge 3B can be attached upside down relative to the attachment order of the panel 1.

[0026] (Construction procedure for Example B) FIG. 8 is an explanatory diagram of the construction procedure of Example B. In (Step 1), the corner vertical frame 2B, support posts 94, upper rails 92, and lower rails 93 are installed in advance.

[0027] In (Step 2), the worker begins the work of installing the pre-attached panel 11 to be placed at the location that will become the corner portion 95. The worker uses a push-in tool to fit the pre-attached panel 11 into the upper rail 92 and lower rail 93, and presses the pre-attached panel 11 against the support 94.

[0028] In (Step 3), the worker pushes the batten 3B toward the pre-attached panel projected surface 114. The worker confirms that the corner vertical frame projected surface portion 2B3 and the batten extension portion 3B4 are firmly overlapped, and then fastens them together with the fixing screw 96.

[0029] In (step 4), the worker attaches the retrofit panel 12 to the panel receiving groove formed in the corner portion 95 consisting of the integrated vertical corner frame 2B and batten 3B.

[0030] As described above, Example B can be installed regardless of the mounting orientation of the panel 1, improving work efficiency and making it easy to use. In addition, the same components can be used even if the mounting orientation of the panel 1 is changed, making it inexpensive and easy to use.

[0031] [Example C] Example C is an example of claim 3. Hereinafter, a reference numeral with a C attached thereto indicates a member of Example C. For example, ledge 3C indicates a ledge of Example C. Example C is an example of a corner portion 95 arranged at a protruding corner, and corresponds to a modification of Example B, which is also arranged at a protruding corner. Figure 9 is an explanatory diagram of the handrail 9 structure of Example C. Figure 9(A) is a cross-sectional view of a corner portion 95 of Example C at a protruding corner. There is a pre-attached panel 11 and a post-attached panel 12. Example C is a corner portion 95 at a protruding corner, and the other side and one side are in the relationship shown in the figure. Figure 9(A) illustrates one side surface 111 of the pre-attached panel, one side surface 121 of the post-attached panel, and the other side surface 123 of the post-attached panel, and for the post-attached panel 12, the out-of-plane direction 124 and the in-plane direction 125 are illustrated. Figure 9(A) illustrates the completed corner structure, with a top board 91 attached to the top of each panel (pre-attached panel 11 and post-attached panel 12).

[0032] (vertical corner frame) 9(B) is a plan view of a vertical corner frame 2C of Example C. FIG. 9(C) is a plan view of a batten 3C of Example C. The vertical corner frame 2C has a shape in which a fitting piece 2C8 protrudes from a hollow frame body. The facing surface 2C1 on one side of the vertical corner frame is provided in a position facing one side surface 111 of the pre-attached panel and holds the one side surface 111 of the pre-attached panel. Details of the contact relationship will be described later, but the correspondence of the points where the vertical corner frame 2C contacts the batten 3C will be explained below. The attachment surface portion 3C2 on one side of the attachment panel is located on one side of the attachment panel 12 and extends in the attachment direction of the attachment panel 12. The surface of the vertical corner frame 2C that abuts against this is the attachment direction abutment portion 2C2 of the vertical corner frame 2C that extends in the attachment direction on one side of the attachment panel 12. The front-facing abutment portion 2C2 of the vertical corner frame 2C has a sliding recess 2C9 on the front panel side, from which the front-facing abutment portion 2C3 extends toward the rear panel side. In other words, the vertical corner frame 2C has the front-facing abutment portion 2C3 that extends in the front direction to the rear panel 12 side of the mounting edge 3C to be attached. The prospective abutment portion 2C3 of this vertical corner frame 2C abuts against the prospective abutment point 3C5 of the prospective abutment portion 3C4 of the edge. A front-facing contact portion 2C3 on the vertical corner frame 2C is connected to a fitting piece 2C8 having a recess 2C81 at its tip.

[0033] (Burst) 9(C) is a plan view of the flange 3C of Example C. The attachment surface portion 3C2 on one side of the rear-attachment panel of the flange 3C and the attachment surface portion 3C3 on the other side of the rear-attachment panel of the flange 3C are arranged opposite each other. Furthermore, a sliding protrusion 3C9 is provided on the end of the front panel 11 side of the front surface portion 3C2 of the rear panel, and protrudes out to the side surface. The role of the sliding protrusion 3C9 will be described later. The corner vertical frame 2C and the batten 3C are connected by pushing the batten 3C toward the prospective surface 114 of the pre-attached panel. The ledge 3C also has a ledge projection direction abutment portion 3C4, which is the surface facing the projection surface 122 of the retrofit panel 12.

[0034] (Panel swallowing groove) A panel swallowing groove for attaching the retrofit panel 12 is formed between the mounting surface portion 3C2 on one side of the retrofit panel of the ledge 3C and the opposing mounting surface portion 3C3 on the other side of the retrofit panel. See Figure 10, which shows how the panel-sweeping groove is formed by the batten 3C and the corner jamb 2C. The pre-attached panel 11 is attached to a panel swallowing groove formed by a facing surface portion 3C1 on the other side of the pre-attached panel located on the edge 3C and a facing surface portion 2C1 on one side of the corner vertical frame 2C on one side of the pre-attached panel 11.

[0035] (Position regulation section) FIG. 10 is an explanatory diagram of the position restriction portion of Example C. Example C is an example in which a position restriction portion not present in Examples A and B is present, and fastening the batten 3C and the vertical corner frame 2C with a fixing screw 96 is not necessarily required. The position restriction portion will be described in detail in the next paragraph, but the worker can complete the connection between the batten 3C and the vertical corner frame 2C without using the fixing screw 96 by engaging or fitting together the components present on the batten 3C and the vertical corner frame 2C that make up the position restriction portion. However, it goes without saying that the worker may also use the fixing screw 96 to fasten the batten 3C and the vertical corner frame 2C.

[0036] (Engagement position regulation portion) The engagement position restricting portion 41C restricts the position of the retrofit panel in the outward direction 124 of the panel surface by engaging the engagement protrusion 3C7 provided on the engagement surface portion 3C6 of the engagement edge 3C with the engagement recess 2C7 of the vertical corner frame 2C. As mentioned above, if necessary, the fixing screw 96 may be fastened at this position.

[0037] (Mating position regulation part) The vertical corner frame 2C has a fitting piece 2C8 extending from the projection direction abutment portion 2C3. The fitting piece 2C8 has a recess 2C81 that fits with the ledge 3C. After the projection direction abutment portion 2C3 of the vertical corner frame 2C abuts the ledge 3C at the projection direction abutment point 3C5, the fitting piece 2C8 changes direction and connects to the fitting piece 2C8, with its tip forming the recess 2C81, which forms a hook-shaped fitting portion. The projection direction abutment portion 2C3 of the vertical corner frame 2C and the ledge projection direction abutment portion 3C4 abut against each other, fulfilling the role of positioning. The engagement of the engagement projection 3C8 of the edge 3C with the recess 2C81 of the vertical corner frame 2C regulates the positions of the edge 3C and the vertical corner frame 2C in the outward direction 124 of the retrofit panel surface.

[0038] (Sliding position regulation part) The sliding position regulating portion 43C is formed at a location where the sliding protrusion 3C9 of the pressing edge 3C is inserted into the sliding recess 2C9 of the vertical corner frame 2C. To connect the batten 3C to the vertical corner frame 2C, the batten 3C is pushed toward the pre-attached panel's projected surface 114. This action inserts the sliding protrusion 3C9 of the batten 3C into the opening of the sliding recess 2C9 of the vertical corner frame 2C, which was already installed before the pre-attached panel 11 was installed. The worker then moves the entire batten 3C so that the sliding protrusion 3C9 of the batten 3C is pushed toward the bottom 2C91 of the sliding recess 2C9. This action simultaneously engages the sliding position restricting portion 43C, the fitting position restricting portion 42C, and the engagement position restricting portion 41C, securing the batten 3C to the vertical corner frame 2C. The sliding position restricting portion 43C restricts movement in the in-plane direction 125 of the retrofit panel and the out-of-plane direction 124 of the retrofit panel.

[0039] The sliding position restricting portion 43C is configured to be difficult to come off because the sliding protrusion 3C9 moves upward and comes into contact with the upper end of the sliding recess 2C9 and stops. Therefore, in the embodiment C, it is possible to omit the fastening of the fixing screw 96 required in the embodiments A and B. As shown in FIG. 10, the worker can also fasten the fixing screw 96 just to be safe, as described above.

[0040] (Can be installed upside down) Figure 11 is an explanatory diagram of the case where the installation order of the panels (11, 12) of Example C is changed. As shown in Figure 9, the corner vertical frame 2C and the batten 3C are not symmetrical in shape. Even if the order of the pre-attached panel 11 and the post-attached panel 12 is changed, both components can be installed upside down, and can accommodate changes in the order of the panels 1. The batten 3C is pressed toward the prospective surface 114 of the pre-attached panel. The installation method is also the same, where the batten 3C is pressed on the post-attached panel 12 side in the out-of-plane direction 124 of the post-attached panel 12, indicated by the arrow 1, and then in the in-plane direction 125 of the arrow 2. When the fixing screw 96 is used for fixing, the fixing screw 96 is driven into the flange engagement surface portion 3C6 of the flange 3C.

[0041] (Construction procedure for Example C) 12 is an explanatory diagram of the construction procedure of Example C. Steps 1 and 2 are the same as those of Examples A and B. In step 3, the edge 3C is pressed toward the pre-attached panel projected surface 114, and the edge 3C is moved toward the vertical corner frame 2C in the direction of arrow 1. This operation positions the component of the position control portion (42C, 43C, 41C) on the edge 3C side and the component on the vertical corner frame 2C side close to each other.

[0042] Next, the pressing edge 3C is lowered in the direction of the arrow 2. The engaging position restricting portion 41C, the fitting position restricting portion 42C, and the sliding position restricting portion 43C engage with each other, preventing movement in the outward direction 124 (left and right direction) of the retrofit panel. In Example C, the worker drives the fixing screw 96 in from the direction of the arrow 3 just to be sure.

[0043] (Step 4) is a step of attaching the add-on panel 12 to the assembled corner portion 95. Through the above steps, the handrail 9 of Example C is assembled.

[0044] (Summary of Effects of the Examples) In Examples A to C, the battens (3A to 3C) can be installed upside down. When installing the panel 1, workers can adapt even if the front and rear of the panel 1 are changed. Furthermore, the corner vertical frames (2A, 2B) in Examples A and B have a structural shape that is symmetrical left and right about the center line, so they can be installed regardless of the front and rear of the panel 1. In this way, Examples A to C are easy for workers to use. The corner portion 95 basically consists of only the ridges (3A to 3C) and the vertical corner frames (2A to 2C), making it easy for workers to handle and convenient to use. Moreover, in the embodiment C, it is possible to omit the fixing screw 96, which is convenient to use.

[0045] Although the embodiments of the present invention have been described in detail with reference to the drawings and various modifiable aspects have been explained, the specific configuration is not limited to these embodiments, and the present invention also includes design changes within the scope of the present invention that do not deviate from the gist of the present invention.

[0046] Furthermore, the various aspects described above can be combined by utilizing each other's techniques, as long as there are no particular contradictions or problems in their purposes, configurations, etc. [Explanation of symbols]
