Description

[Detailed explanation of the idea] This invention relates to handrails.

In the conventional example, the balusters were inserted into the main body of the handrail, and the balusters were connected and fixed to each other.

However, since the slope pitch of handrails for stairs generally differs from site to site, they cannot be manufactured in a factory, and all must be manufactured on-site, which has the drawback of requiring a large amount of processing time and skilled skills.

Therefore, the aim of this invention is to provide a handrail that does not require on-site fabrication.

An embodiment of this invention is shown in FIGS. 1 to 5.

That is, in this stair handrail, the handrail main body 1 is made of irregularly shaped laminated wood, and as shown in the figure, both ends of a C-shaped cross section (channel) are further extended inward and face each other with grooves 1a,
lb, the lower opening 2 forms a recess 3 extending in the longitudinal direction.

The irregularly shaped laminated wood is formed into the above shape by laminating sliced veneers and pressing them with adhesive, and has elasticity.

Therefore, a handrail 4 is processed and fixed in a factory to a stair tread (not shown), and the opening 2 of the handrail body 1 is fitted and pushed into the upper end 5 of the plurality of balusters 4 installed on site as shown in Fig. 2. As shown in FIG. 3, the handrail body 1 is held fixed by its elasticity.

Furthermore, a curved flying reversal spring 7 is fitted in an upwardly convex direction as shown in FIG. Insert the joint plate 8 having a shape between the grooves 1a and lb, and push the joint plate 8 against the spring resistance of the reversing spring 7, so that the spring 7 is reversed and becomes convex downward as shown in Fig. Both ends of the spring 7 are supported by the upper surfaces of the grooves 1a and 1b, and the middle part of the spring 7 moves the joint plate 8 into the grooves 1a and 1b.
The press is fixed to the bottom surface of b.

This joint board 8 also has the function of supporting the baluster 4 in the lateral direction.

As described above, the handrail of this invention has a resilient handrail body with four parts formed on the lower surface and extending in the longitudinal direction, so the handrail body can be fixed by being pushed into the upper end of the baluster, and the slope can be fixed. It can be easily inserted regardless of the pitch, and since the handrail body can be processed at a factory, it has the effect of eliminating the need for on-site processing and skilled skills as in the past.

In addition, because the joint plate was inserted into the horizontal groove where the baluster is not located and pressed and fixed with the inverted curved leaf spring, the inside of the recess can be hidden by the joint plate, and the joint plate can be easily fixed with the inverted spring. .
