Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a device for joining the upper umbrella of a handrail and a support.

(Prior art) Conventionally, when joining a round pipe support with a diameter smaller than the upper head of a handrail in a perpendicular state to the round pipe upper head of the handrail, the end face of the support was hollowed out to fit the outer circumferential surface of the upper head of the handrail. The scraped portion was then brought into close contact with the outer circumferential surface of the upper Kasagi and the two were joined with screws, or the two were joined by welding at the same close location.

(Problem that the invention aims to solve) Therefore, in the past, the end face of the support pillar had to be gouged out and cut down to fit the outer circumferential surface of the upper kasagi, which was a troublesome and time-consuming process, which was disadvantageous in terms of cost. Ta.

The former method of screwing has problems in terms of strength, stability, workability, and cost, while the latter method of welding has problems such as deterioration of commercial value due to bead protrusion and poor workability. It was hot.

(Means for Solving the Problems) This invention was made to solve the above problems, and is constructed as follows.

In other words, the device for joining the upper cap of the handrail and the post of this invention has a divided configuration of the marukasa and the marukasa and the upper cap of the round pipe is separably engaged with each other, and the upper cap of the round pipe is smaller in diameter than the upper cap. A round pipe support with multiple screw pockets in the axial direction on the inner surface, a support with a curved end surface that matches the outer peripheral surface of Kamikasagi, and multiple screw insertion holes on the outer peripheral edge, and a joint plate on the lower surface of the outer peripheral surface of the same diameter. It consists of a joint made of plastic, rubber, metal, etc., in which a screw insertion hole whose inner diameter and outer diameter are approximately equal to each other, and a circular cylinder part with corresponding notches are concentrically integrated, and each notch is connected to each screw pocket. Fit the cylindrical part of the joint into the tip of the column, bring the curved end surface of the joint into close contact with the upper cap, and screw the screw into the bis pocket through the screw insertion hole of the upper cap. It is made by integrally joining.

Next, embodiments of this device will be described below with reference to the drawings.

〔Example〕

First, 1 is an upper cap of an aluminum alloy round pipe which has a divided configuration of a Marukasagi 1a and a Marukasagi receiver 1b and is separably engaged with each other. Reference numeral 2 denotes a support made of an aluminum alloy round pipe, which has a diameter smaller than that of the upper cap 1 and has four axially extending bis pockets 3 formed at equal intervals on its inner surface. Furthermore, 4 is a curved end surface 5a that matches the outer circumferential surface of the upper Kasagi 1, and has four screw insertion holes 7 at equal intervals on the outer circumferential edge of the support column 2.
On the lower surface of the joint plate portion 5 having the same diameter outer peripheral surface 5a, there is a screw insertion hole 7 whose inner diameter and outer diameter are approximately equal to that of the strut 2, and a corresponding position 4.
This is a joint made of plastic, rubber, metal, etc., in which a circular cylindrical part 8 having individual notches 9 is concentrically integrated. Note that 6 is a central hole.

Therefore, in this devised joining device, each notch 9 is engaged with each bis pocket 3, the round cylindrical portion 8 of the joint 4 is fitted into the tip of the column 2, and the curved end surface 5a of the joint 4 is fitted.
Closely connect it to the upper Kasagi 1 and insert each screw through hole 1 of the upper Kasagi 1.
0. Pass the four screws 11 through each screw insertion hole 7, respectively.
are screwed into each bis pocket 3 and integrally joined.

(Effects of the invention) As described above, this invented joining device joins the upper Kasagi and the support via a joint.
This eliminates the troublesome labor and effort of gouging out the end face of the round pipe support each time to fit the round pipe upper cap as in the past, and also eliminates the need for welding, which gives it a beautiful appearance and contributes to improving product value. There is an effect.

In particular, in this invention, the connection is made by screwing in multiple screws at evenly spaced intervals, so the three parts, the upper kasagi, the pillar, and the joint, are connected and joined together in a strong, stable and reliable manner. So, to stop the pillar from rotating,
There is no need for joint fixing, the number of parts is small, composition work can be done easily on site with good workability, and the work is simple, efficient, and can be provided at low cost. In addition, by constructing the joint with plastic or rubber, the curved end surface of the joint and the outer circumferential surface of Kamikasagi have good water-blocking properties, which prevents rainwater from flowing in and prevents deterioration and erosion of each component. There is.
