An engagement concave portion is formed to rotatably engage with the engagement convex portion formed at both the upper and lower ends, and the above-mentioned retaining convex portion is formed at both the upper and lower ends of the small column, and the above-mentioned engagement convex portion is formed at both the upper and lower ends of the small column. The vicinity of the retaining convex portion is shaved, and is shaped so that the small pillar can be attached to the crosspiece in response to changes in the angle between the small pillar and the crosspiece.

[Function] The handrail according to the present invention first attaches the main material of the lower crossbar,
Next, the engaging convex portions of the small pillars are engaged with the four engaging parts of the main material of the lower crosspiece, and then the auxiliary members of the lower crosspiece can be accessed. Next, the engagement concave portion of the main member of the upper crossbar is engaged with the engagement convex portion of the upper portion of the small pillar, and then the auxiliary member of the upper crosspiece is attached. Since the engagement recesses of the main material are rotatably engaged with the engagement protrusions formed on both the upper and lower ends of the small pillar, the handrail can be easily attached.

[Example] The handrail will be described in detail below using an example of the handrail according to the present invention shown in the drawings. FIG. 1 is a perspective view showing the relationship between the main material and the auxiliary material of the lower crosspiece portion of the first embodiment, and FIG. 2 is a perspective view showing the relationship between the engagement recess of the lower crosspiece and the engagement convex portion of the small pillar. , Figure 3 is a perspective view showing the small pillar attached to the lower crosspiece, Figure 4
The figure is a perspective view showing the relationship between the main material and the auxiliary material of the upper crosspiece, FIG. 5 is a side view of the upper crosspiece, and FIG. 6 is a perspective view of the completed handrail. Here, 1 is the upper crosspiece, 11 is the main material of the upper crosspiece, 12 is the auxiliary material of the upper crosspiece, 13 is the engagement recess of the upper crosspiece, 2 is the lower crosspiece, 21 is the main material of the lower crosspiece, 22
Reference numeral 23 indicates the auxiliary material of the lower crosspiece, 23 indicates the four holding parts of the lower crosspiece, 3 indicates the small pillar, 31 indicates the engagement convex portion of the small pillar, and 32 indicates the shaved portion of the small pillar.

This embodiment has an upper crossbar 1 and a lower crossbar 2.

This is a handrail in which small pillars 3 are arranged between these, and the embodiment shown on the right side of Fig. 6 is a horizontal handrail, and the embodiment shown on the left side of Fig. 6 is an inclined handrail of a staircase. . This embodiment is applicable to any case.

Both the upper crosspiece 1 and the lower crosspiece 2 consist of a main member 11.21 and an auxiliary member 12.22. Further, the main member 11.21 is formed with engagement recesses 13.23 that rotatably engage with the engagement protrusions 31 formed at both upper and lower ends of the small pillar 3. The engaging concave portions 13.23 of the main member 11.21 rotatably engage with the engaging convex portions 31 formed on both the upper and lower ends of the small pillar 3, so even when the handrail is horizontal, it is tilted. Even if the trabeculae 3
can be rotated relative to the upper crossbar 1 and the lower crossbar 2, making it easy to attach a handrail. In this embodiment, the engaging protrusion 31 has a cylindrical shape, but is not limited to this embodiment, and may have a spherical shape, for example.

The above-mentioned engagement projections 31 are formed on the upper and lower ends of the small pillar 3, and the vicinity of the engagement projections 31 at both the upper and lower ends of the small pillar 3 are shaved, so that the shaved portions 32 of the small pillar 3 are The small post 3 and the crosspiece 1.2 are formed in such a way that the small post can be attached to the crosspiece according to any angle change.

Since the small pillar 3 is formed with a shaved portion 32, when the small pillar 3 is rotated relative to the upper crosspiece 1 and the lower crosspiece 2 as described above, the small pillar 3 is rotated relative to the upper crosspiece 1 and the lower crosspiece 2. 2 and does not impede rotation.

The handrail according to the above embodiment can be installed in the same way whether it is a horizontal handrail such as a balcony or an inclined handrail such as a staircase. In either case of inclination, first attach the main member 11 of the lower crosspiece 1, then engage the retaining convex portion 31 of the small pillar 3 with the engagement recess 13 of the main member 11 of the lower crosspiece Attach the auxiliary material 12 of the crosspiece 1. Next, the engagement concave portion 23 of the main member 21 of the upper crosspiece 2 is engaged with the retaining convex portion 31 on the upper part of the small pillar 3, and then the auxiliary member 22 of the upper crosspiece 2 is attached. The engaging concave portions 13.23 of the main member 11.21 rotatably engage with the engaging convex portions 31 formed at both ends of the lower part of the small pillar 3, so it can accommodate differences in the inclination angle of the handrail. Handrails can be installed easily, quickly, and accurately. As described above, the installation of the handrail is completed.
