In FIGS. 4 and 5, reference numeral 13 denotes a ridge 13 integrally formed at a position opposite to the inner surface of each strut 1 in order to facilitate insertion of the sheath tube 13 into the inner hole of the strut 1. belongs to.

As shown in FIG. 2, the headboard 2 has a horizontal base plate portion 20 and a peripheral wall portion 21 integrally formed on the base plate portion 20, and both end portions are formed on the lower surface of the base plate portion 20. A pair of ridges 23, 23 is provided at the position, and a pair of connecting pieces 22, 22 is integrally provided at the intermediate position over the entire length. Each connecting piece 22, 22 is a connecting piece 11,
In this embodiment, the distance d1 between the outer surfaces of the connecting pieces 22 is made equal to the distance d2 between the inner surfaces of the connecting pieces 11 of the support columns 1.

As shown in FIGS. 3, 4 and 6, the lower rail 3 has a horizontal support plate portion 30 and side plate portions 31 and 31 formed by bending at both ends of the support plate portion 30. On the upper surface of the support plate portion 30, a pair of connecting pieces 32, 32 are integrally projected over the entire length. The connecting pieces 32, 32 are provided at intervals corresponding to the distance between the connecting pieces 11, 11 of the support 1. In this embodiment, the distance d3 between the outer surfaces of the connecting pieces 32 is set to the connection of the support 1. The distance d2 between the inner surfaces of the pieces 11
It is matched with.

Notch grooves 33 are formed on both end surfaces of the support plate portion 30 of the lower rail 3 outside the base end portions of the connecting pieces 32, and the support columns 1 are connected to the notch grooves 33, respectively. The piece 11 is engaged and overlapped with each connecting piece 32 of the lower rail 3 and integrally fixed by the fixing tool 7. The groove depth of each of the cut grooves 33 is matched with the protruding width of each of the connecting pieces 22 of the support column 1, whereby the cut groove 33 is formed.
The end surface of the lower bar 3 and the outer surface of the support column 1 are in close contact with each other when the connection piece 22 is engaged with the connection piece 22. In FIG. 4, 34 is a drain hole for draining water accumulated in the groove between the connecting pieces 32.

As shown in FIG. 4, each of the standing grids 4 has the following structure.
The horizontal cross-section has a rectangular shape, and a plurality of standing lattices 4 are arranged at equal intervals between the umbrella tree 2 and the lower crosspiece 3, and the upper end of each standing lattice 4 has connecting pieces 22, 22 of the umbrella tree 2. In the meantime, the lower end is engaged between the connecting pieces 32, 32 of the lower rail 3, respectively, and the upper end and the lower end of each vertical grid 4 are integrally fixed to the connecting pieces 22, 32 by the fasteners 8, respectively.

The handrail having the above-mentioned structure can be assembled in any order. For example, the lower rail 3 is first assembled to each of the columns 1 vertically installed on the floor surface 5, and then the headboard 2 and Assemble a plurality of vertical grids 4.

That is, in order to connect the columns 1 and 1 to the lower bar 3, the connecting pieces 11 of the column 1 are inserted into the cut grooves 33 at both ends of the lower bar 3 and the lower bars 3 are connected to each other. After overlapping the piece 32 and positioning it at a predetermined height, the connecting piece 11,
The 32 parts are integrally fixed.

In order to connect the columns 1 and 1 to the headstock 2, the connecting pieces 22 of the headstock 2 are inserted into the notches 12 at the upper ends of the pillars 1 and the connecting pieces 11 of the pillar 1 are connected. After the positioning is performed by stacking with, the connecting pieces 11 and 22 are integrally fixed by the fixing tool 6.

Prior to fixing the headboard 2 to each of the columns 1,
A plurality of upright grids 4 are arranged at equal intervals between the headstock 2 and the lower crosspiece 3, and the upper ends of the respective upright grids 4 engage with the grooves between the connecting pieces 22 of the headboard 2, and also the respective upright grids. The lower end of 4 is engaged with the groove between the connecting pieces 32, 32 of the lower bar 3 to position each vertical grid 4, and then the upper and lower ends of each vertical grid 4 are connected to each connecting piece 22, 3.
It is integrally fixed to 2 by a fixing tool 8.

As described above, when assembling the support column 1 and the lower crosspiece 3 and assembling the support column 1 and the headstock 2, the connecting pieces 11 and 22 are inserted into the cut grooves 33 and 12, respectively. Assembling of the crosspiece 3 and each vertical grid 4 is realized by engaging the upper and lower ends of each vertical grid 4 with the groove between the connecting pieces 22 and 22 and the groove between the connecting pieces 32 and 32, respectively. Further, the connection between the support 1 and the headstock 2 is made by fixing the overlapping connection pieces 11, 22 and the connection between the support 1 and the lower crosspiece 3 is made by fixing the polymerization connection pieces 11, 32. 2 and the lower rail 3 and each vertical grid 4 are respectively realized by fixing the upper and lower end portions of each vertical grid 4 and the connecting pieces 22 and 32, and a special connecting metal fitting is required. The handrail can be assembled inexpensively and easily without doing so.

[0022]

As described above, according to the present invention, when assembling the support pillar, the lower crosspiece, and the headstock, a pair of connecting pieces are projectingly provided on these constituent members, and the connecting pieces are engaged at the connecting positions of the connecting partners. A notch groove to be inserted is provided to integrally fix the connecting pieces that overlap each other when the connecting pieces and the notch groove are engaged, and the upper and lower ends of the plurality of vertical grids are connected between the connecting pieces of the head tree and the lower rail. Since they are engaged with each other and integrally fixed, the handrail can be easily assembled without using a special connecting fitting such as a head guard or an L-shaped angle as in the conventional example. Further, since no special connecting metal fitting is required, the number of parts is reduced, and an inexpensive handrail can be provided.
