Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a handrail cap connector used for connecting a plurality of handrail caps formed in a tubular shape.

[Conventional technology]

Generally, welding is often used to connect multiple tubular bodies, but when welding is used to connect handrail caps formed in a tubular shape, the weld bead is exposed on the outer surface and is unsightly. As shown in Figure 2, conventionally, in order to form a handrail by connecting a plurality of handrail caps, 1, 1... to each other, a third
As shown in the figure, a connecting rod 2 is inserted through a handrail cap 1, and each of the handrail hats 1, 1 is fixed to the connecting rod 2 with screws 3.

[Problem that the invention attempts to solve]

However, in such a conventional example, if the outer circumferential dimension of the connecting rod 2 does not exactly match the inner circumferential dimension of the handrail cap 1, a step may occur at the joint between the two handrail caps 1, 1 to be connected. On the other hand, manufacturing the above-mentioned dimensions with high precision increases the cost and also reduces the workability when inserting the connecting rod 2 with a small insertion gap into the handrail cap 1. It had the disadvantage that it decreased.

The present invention was made in order to eliminate such drawbacks, and an object of the present invention is to provide a handrail cap wood connector that is easy to manufacture and has good workability.

[Means for solving problems]

In FIG. 1, a balustrade coupling according to the invention is shown corresponding to its embodiment.

In this FIG.
are connected by a connecting piece 6, and these pressing members 5, 5 are designed to have an appropriate angle θ between their straight portions 5a, 5a.

Reference numeral 7 indicates an expansion member formed in a trapezoidal shape, which is installed between the straight portions 5a, 5a of the pressing members 5, 5, and is screwed into a fastening screw 8 inserted through the connecting piece 6 of the main body 4 so as to be retractable. has been done.

[Effect]

Next, a method for connecting two handrail caps 1, 1 using the handrail cap joint according to the present invention will be explained. After inserting both ends of the main body 4 housed between the pressing members 5, 5, the ends 1a, 1a of the two handrail caps, 1, 1 are brought into contact.

Next, the fastening screw 8 is inserted into the connecting piece 6 of the main body 4 from the outside of the handrail cap 1 and screwed into the expansion member 7.
When the fastening screw 8 is further tightened, the pressing member 5 is drawn upward by the fastening screw 8, and its side wall 7
Pressing members 5, 5 while deforming the connecting piece 6 by a.
It becomes a state where it is pushed outward.

As a result, the curvature portion 5b of the pressing member 5 is strongly pressed against the inner wall of the handrail cap 1, and the two handrail caps 1, 1 are firmly connected to each other via the main body 4.

That is, according to the connector of the present invention, by displacing the pressing member 5 of the main body 4 outward, which is formed so that it can be easily fitted into the handrail cap 1, it is fixed inside the handrail cap 1. Therefore, there is no need to manufacture the main body 4 and the like with high precision, and the workability can be improved.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment in which two expansion members 7 are provided corresponding to each handrail cap 1, 1, and both ends fit into the inner circumference of the handrail cap 1, 1. In this embodiment, the main body 4 is made of, for example, an aluminum alloy or the like, and has an overall length sufficient for
The member 5 and the connecting piece 6 are integrally formed, and the connecting piece 6 is formed to be slightly thin so that it is easily deformed when the pressing member 5 is pushed and expanded by the expanding member 7. Two pressing members 5, 5
may be mechanically connected by a connecting piece 6 formed separately from this.

In addition, a plurality of uneven grooves 9, 9... are carved on the curvature portion 5b of the pressing member 5, in order to improve the frictional force with the inner circumference of the handrail cap 1 and increase the connection strength. .

The expansion member 7 is made of a material such as an aluminum alloy, and has two opposing faces at an angle that is approximately the same as or slightly larger than the angle θ formed by the straight portion 5a of the pressing member 5 of the main body 4. It is formed into a trapezoidal cross-section with side walls 7a, 7a, and a screw hole 7b is bored therethrough from the top surface to the bottom surface.

On the other hand, as the fastening screw 8, it is also possible to use a normal hexagonal bolt, but in this embodiment, the fastening screw 8, in its attached state,
As shown in Figure 1b, since it is stored inside the handrail cap 1, a bolt with a hexagonal guide hole formed in the head 8a is used to facilitate the installation work. , and is adapted to be inserted through an insertion hole 1b formed in the handrail cap 1 and screwed into an expansion member 7, which will be described later.

In addition, in FIG. 1b, 10 indicates a cylindrical cover used to cover up the connecting part of the two handrail caps 1, 1, and the cover fixing bolt 11 is inserted into the cover 10. , is attached by screwing its lower end to the expansion member 7.

Further, in the embodiments shown above, the case where one main body 4 and two expansion members 7, 7 are used has been described, but the connector of the present invention is not limited to this, and the pressing of the main body 4 It goes without saying that the member 5 may be expanded by a single expanding member 7, and in this case, the end portions 1b of the handrail caps 1 to be connected are each semicircular so as to form a perfect circle in the connected state. It is desirable to form a notch and to allow the fastening screw to pass through this notch.

[Effect of idea]

As is clear from the above description, according to the handrail cap joint according to the present invention, the main body is formed so as to be able to fit inside the handrail cap, and by displacing the pressing member of the main body outward by the expansion member. Since it is fixed inside the handrail cap, there is no need to manufacture the main body etc. with high fitting precision, and the main body can be easily inserted into the handrail cap, so the workability can be improved. can.
