DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. A first embodiment of the present invention will be described with reference to Figs. 1 to 6. Fig. 1 is a side view of a main part of a passageway according to the embodiment, Fig. 2 is a plan view of the same, and Fig. 3 is a front view of the same. Fig. 4 is an explanatory view of a first support member in the embodiment, with (a) being a plan view, (b) being a front view, and (c) being a side view. Fig. 5 is an exploded perspective view of the support member. Note that in Fig. 2, the footboard member 2 is shown in a see-through state.

[0011] The passage 100 includes a footboard member 2 and a support member (hereinafter simply referred to as a "support member") 1 that supports the footboard member.

[0012] The support member 1 is composed of two first support members 10 and a second support member 20 bridging the two first support members 10.

[0013] The first support member 10 has a first support portion 11 extending in a first direction Y, and one or more connecting portions 12 (12a, 12b). The connecting portion 12 is provided integrally with the first support portion 11 and protrudes in a second direction X intersecting the first direction (orthogonal in this embodiment), and the connecting portion 12a and the connecting portion 12b are provided on opposite sides of the first support portion 11. In this embodiment, the first support member 10 has four connecting portions 12. The connecting portions 12 may also be recessed portions.

[0014] The first support portion 11 of the first support member 10 is provided with at least one recess 13 (eight in this embodiment) on the support surface 11a side that supports the footboard member 2. The first support portion 11 is also provided with at least one recess 14 (eight in this embodiment) on the surface 11b side opposite the support surface 11a that supports the footboard member 2 (this becomes the support surface when the first support portion 11 is turned upside down).

[0015] The second support member 20 is an elongated member, and both ends are connected to the connecting portion 12 of the first support member 10. In this embodiment, one end of the second support member 20 is connected to the connecting portion 12a of one first support member 10, and the other end of the second support member 20 is connected to the connecting portion 12b of the other first support member 10.

[0016] The connection between the connecting portion 12 of the first support member 10 and the end portion of the second support member 20 is fixed and detachably connected by a fastening member 15 composed of, for example, a bolt 15a and a nut 15b. A through hole 16 for passing the bolt 15a is provided in the connecting portion 12 of the first support member 10, and a through hole 21 for passing the bolt 15a is provided in the end portion of the second support member 20. The fastening member 15 may be a screw such as a coarse sled.

[0017] Next, a method for installing the passage 100 will be described.

[0018] First, a process is performed in which a support member 1, which is formed by connecting and fixing a second support member 20 having a length L (see FIG. 5) corresponding to the width (length in the second direction X) W (see FIG. 2) of the passage 100 to be installed, and two first support members 10, is installed on the passage contact surface.

[0019] Here, a plurality of second support members 20 having different lengths L are prepared as the second support member 20, and the second support member 20 having the required length L can be selected and used. Also, the second support member 20 and the first support member 10 may be connected in advance or on-site.

[0020] Then, the required number of step members 2 are placed on the support surface 11a of the first support portion 11 of the first support member 10 of the support member 1 and the support surface 20a of the second support member 20, and the step members 2 are fixed to the first support member 10 and the second support member 20 using fastening members 17 such as threads, thereby completing the walkway 100.

[0021] In this way, the width W of the passageway 100 (or landing) in the second direction X can be changed simply by changing the length L of the second support member 20, without changing the first support member 10. This eliminates the need to prepare multiple first support members according to the width of the passageway or landing to be installed, makes it possible to easily accommodate changes in the installation width, and improves the degree of freedom in the installation width.

[0022] Next, a second embodiment of the present invention will be described with reference to Fig. 6. Fig. 6 is an explanatory plan view of a passage according to the second embodiment.

[0023] In this embodiment, the support member 1 that supports the footboard 2 is configured by connecting one end of each of a plurality of second support members 20 to one first support member 10.

[0024] In this manner, one end side of the second support member 20 can be connected and fixed to the first support member 10 to form a passage 100 (or a landing).

[0025] Next, a third embodiment of the present invention will be described with reference to Fig. 7. Fig. 7 is an explanatory plan view of a passage according to the third embodiment.

[0026] In this embodiment, the support member 1 has two rows of two first support members 10 connected in the first direction Y, and both ends of the second support member 20 are connected and fixed to the connecting portions 12 of each of the first support members 10 in each row. The two first support members 10 can be connected by, for example, a connecting plate 18 and a fastening member 19.

[0027] In this way, by connecting a plurality of first support members 10 in the first direction, a passage 100 (or a landing) of a required length can be easily provided. In this embodiment, the length of the passage 100 is twice as long as that of the first embodiment.

[0028] Next, a fourth embodiment of the present invention will be described with reference to Fig. 8. Fig. 8 is an explanatory plan view of a support member according to the fourth embodiment.

[0029] In this embodiment, the support member 1 has four rows of two first support members 10 connected in the first direction Y, and both ends of the second support member 20 are connected and fixed to the connecting portions 12 of each first support member 10 in each row adjacent to each other in the second direction.

[0030] In this way, by arranging a plurality of first support members 10 in the second direction, a passageway or landing of a required width can be easily provided. In this embodiment, the width of the passageway or landing is three times that of the third embodiment.

[0031] Next, a fifth embodiment of the present invention will be described with reference to Figures 9 to 11. Figure 9 is a side view of a passage according to the fifth embodiment, Figure 10 is a plan view of the same, and Figure 11 is a front view of the same.

[0032] In this embodiment, the passageway 100 of the first embodiment is provided with a handrail 5 along the first support portion 11 of the first support member 10.

[0033] The handrail 5 comprises a handrail beam 51 and two supports 52, 52 that support both ends of the handrail beam 51.

[0034] The support pillar 52 is fixedly held to the footboard member 2 by first holding means 61 , and is fixedly held to the outer surface of the first support portion 11 of the first support member 10 by second holding means 62 .

[0035] Here, the first holding means 61 includes a plate-shaped holding member 61a having one end fixed to the footboard member 2, and approximately semicircular band fittings 61b, 61c for clamping the support post 52 therebetween.

[0036] The retaining member 61a is disposed between the recess 13 provided in the first support portion 11 of the first support member 10 and the footplate member 2, and one end is fixed to the bottom side (lower side) of the footplate member 2 by a fastening member 65 such as a bolt and nut.

[0037] The band metal fitting 61b is integrally provided on the other end of the holding member 61a. Note that the holding member for holding the lower end of the support 52, such as the band metal fitting 61b, may be separate from the holding member 61a and may be connected to the holding member 61a by a fastening member or the like.

[0038] Then, by clamping the support 52 between the band fittings 61b and 61c and tightening the band fittings 61b, 61c with fastening members 66 such as bolts and nuts, the lower end of the support 52 is fixed to the footboard member 2 via the retaining member 61a of the first retaining means 61.

[0039] The second holding means 62 comprises a holding member 62a fixed to the first support portion 11 of the first support member 10 with fastening members 67 such as bolts and nuts, and a bracket 62b fixed to the lower end of the support pillar 52.

[0040] Then, by fastening the retaining member 62a and the bracket 62b with fastening members 68 such as bolts and nuts, the lower end of the support pillar 52 is fixedly held to the side of the first support portion 11 of the first support member 10 by the second retaining means 62.

[0041] Thus, in this embodiment, the recess 13 provided in the first support member 10 forms a space between the first support member 10 and the footboard member 2 through which the retaining member 61a for fixing the post 52 of the handrail 5 to the footboard member 2 passes.

[0042] This makes it possible to easily fix and hold the support post 52 of the handrail 5 to the step member 2.

[0043] The second holding means 62 may be a means for fixing the lower end of the support pillar 52 to the side surface of the first support part 11 with fastening members such as bolts and nuts.

[0044] In each of the above embodiments, recycled plastics are used for the footboard member 2, the first support member 10, the second support member 20, and the third support member 30. In the case of recycled plastics, the outer shell has sufficient strength and rigidity, but the inside has lower strength and rigidity than the outer shell. Therefore, when fixing a holding member that holds the handrail post to the footboard member, by providing recesses in the first support member 10, the second support member 20, and the third support member 30 in advance, there is no risk of a decrease in strength and rigidity compared to cutting the recesses later.

[0045] In each of the above embodiments, an example has been described in which the support member 1 supports the tread member 2 that constitutes the passageway 100, and a method for installing the passageway 100. However, the present invention can be similarly applied to the case in which a staircase or a landing for a passageway is formed instead of the passageway 100.

[0046] In other words, the support member 1 can be a support member that supports the step members of the landing. Also, the first support member 10 and the second support member 20 that constitute the support member 1 can be connected to form a landing. Furthermore, the method for installing the passage can be directly implemented as a method for installing the landing.

[0047] Furthermore, in each of the above embodiments, an example has been described in which a recess is provided on the surface side of the first support member that supports the footboard member, but a configuration in which no recess is provided may also be used. [Explanation of symbols]
