Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a round pipe handrail with a cap.

(Prior Art) In recent years, various handrails with caps made of aluminum alloy materials, which are lightweight and have excellent rust and corrosion resistance, have become known. Among these, round pipe handrails with caps using round pipes (pipe top caps) and supports have the advantage of having fewer parts, simple structure, relatively easy assembly work, and excellent strength. , demand has been increasing recently.

(Problem that the invention aims to solve) However, in the conventional round pipe handrail with a cap, when joining the round tube support and the round tube upper hat, first the upper end of the round tube support is made to fit with the round tube cap. The hollowed out part was then cut in a similar manner, and the cut part was brought into close contact with the outer peripheral surface of the round cylinder cap, and the two were joined together by welding.

Therefore, due to welding, the joint has an extremely ugly appearance due to protruding beads and the like, which significantly reduces the commercial value.

In addition, various operations such as cutting the joint of the cylindrical support and welding including attachment to the lower kasagi are troublesome, inefficient, and costly.

(Means for Solving the Problems) This invention was made to solve the above problems, and its purpose is to provide a round pipe handrail with a cap, which will be described below.

This invention will be described in detail below with reference to the drawings. 1 is a cross-sectional lower kasagi made of aluminum alloy, etc., and its upper web 1a has a slightly curved R ( It is formed on the R) surface. And this Shimokasagi 1
is fitted onto the frame 1 so as to come into contact with the upper surface of the mounting seat plate 3 on the frame 2. Note that 4 is a protruding bolt attached to the mounting seat plate 3, which penetrates the lower cap 1 and protrudes upward. Reference numeral 5 denotes a cylindrical support made of aluminum alloy or the like, into which a fitting nut 6 having a female threaded portion 6a which is screwed into the bolt 4 is fitted into the lower end thereof and is fixed together by adhesive or the like. Therefore, the above-mentioned cylindrical column support 5 is fixedly hung on the lower cap 1 by screwing the female threaded portion 6a onto the protruding bolt 4.

In addition, since the upper surface web 1a of the lower Kasagi 1 is an R (R) surface as described above, the protruding bolt 4 of the cylindrical column support 5 can be strongly screwed, and there is no risk of rainwater etc. accumulating on the upper surface web 1a. Drains well. Next, 7 is a round cylinder support 5 with a curved upper surface 8a that is compatible with the outer peripheral surface of the round cylinder upper cap 10 made of aluminum alloy or the like.
The joint part 8 having the same diameter outer circumferential surface 8b is a cylindrical central column having a cap screw hole 9 at the center of a concentric integral body at the upper end, and is made of aluminum alloy or hard plastic like the fitting nut 6. Note that 9' is a fine hole portion of the cap screw hole 9'. Therefore, in this invention, first, the round cylinder upper cap 10 is brought into close contact with the curved upper surface 8a of the joint part 8, and is screwed and fixed to the round cylinder middle pillar 7 with the set screw 11 passing through the cap screw hole 9. Then, the cylindrical middle pillar 7 with the cylindrical upper caps 10 attached to the upper end is fitted onto the upper part of the cylindrical pillar 5, and fixed on the house side with the countersunk screws 12 as shown in Figures 1 and 2. That's what happens.

(Detailed explanation of the invention) As mentioned above, the round pipe handrail of this invention is connected to the round cylinder upper cap 10 via the round cylinder middle pillar 7 having the joint part 8 that fits the outer peripheral surface of the round cylinder upper cap 10. Cylinder support 5
Since the set screw 11 is used to fix the round cylinder support 5 and the round cylinder upper cap 10, the joint between the round cylinder support 5 and the round cylinder upper cap 10 is not ugly unlike conventional welding, and the appearance is very neat and clean, which is an advantage that can significantly improve the product value. It has a positive effect.
In addition, composition work can be performed on-site, and the work is easy and has good workability, and it is efficient and can be provided at low cost. Furthermore, since the upper surface web 1a of the lower Kasagi 1 has an R (R) surface as described above, the protruding bolt 4 of the cylindrical support 5 can be strongly screwed, and there is no risk of rainwater etc. accumulating on the upper surface web 1a. It has the effect of draining water easily.
