Description

[Detailed explanation of the invention] This invention is applicable to buildings, factories, ships, large mechanical equipment, parking lots,
It relates to top rails used as handrails and various shelf caps installed in stadiums, baseball fields, etc., and as guard rails installed in buildings, factories, ships, elevators, automobile roads, etc.

Conventionally, the caps installed on the stairs of buildings and used as handrails are composed of metal caps that are passed between the supports, and vinyl band rails that are placed over the caps.
A hot air device is used to cover the Kasagi holder with a vinyl band/rail.

In addition, the guard rails that have been installed in buildings to date are rigid bodies, and when an impact load is applied, their elastic deformation characteristics and cushioning effect as a beam are insufficient, and they also have insufficient elastic deformation characteristics and cushioning effects on walls and panels. The structure of the installation was complex, the number of parts was large, and the construction was complicated.

The purpose of this invention is to have an excellent buffering effect, and to use it for handrails, fences, etc.
It can be used for curved parts such as caps, guard rails, etc., simplifying the structure, making assembly extremely easy, reducing the number of parts, and making installation easier. It has excellent applicability to corners and corners, reinforces strength, is robust, and can be manufactured at low cost.
Another object of the present invention is to provide a top rail that allows the rail body to be rolled up and facilitates packaging and transportation.

In order to solve these problems, the top rail of this invention has a thin inner shielding part that forms a core material insertion hole penetrated in the length direction, and a thick walled part that is arranged at appropriate intervals in the radial direction from the inner shielding part. A large number of voids are spaced apart at appropriate intervals and penetrated in the length direction around the core material insertion hole to form an outer shielding portion, and further, the voids extend in the length direction and are A soft synthetic resin rail body that has a notch that communicates with the core insertion hole and is formed from the inner shielding part to the outer shielding part, and the rail body that passes through the notch and connects to the core insertion hole. It is more effective with the metal rail core material that is fitted into it.

Hereinafter, preferred specific examples of the top rail according to this invention will be described with reference to the drawings.

1 to 3 show a specific example 10 of the top rail of this invention used in a wall-mounted handrail 30 on a staircase 42 of a building 40.

The top rail 10 is a rail body 1 made of soft resin.
1 and a metal rail core material 12 that is fitted into the rail body 11, and the rail body 11 has a core material fitting that is penetrated in the length direction at the center, as shown in FIGS. 2 and 3. Insertion hole portion 13, core material insertion hole portion 13
They are spaced apart at appropriate intervals around the core material insertion hole 13 so as to form a thin inner shielding part and a thicker outer shielding part at an appropriate interval in the radial direction from the inner shielding part. A large number of voids 20 penetrated in the length direction, and a notch extending in the length direction and communicating with the core fitting hole 13 formed from the inner shielding part to the outer shielding part. 14 and a seam 15 that closes the notch 14, and is integrally extruded in an extrusion molding machine.

As can be understood from FIGS. 2 and 3, the joint 15 is configured to snap into an engagement groove 18 formed in one notch surface 16 of the notch 14, and to be engaged with the engagement groove 18 in a snap manner. A locking protrusion 19 formed on the other notch surface 17 of the notch 14
It is more structured as follows.

Of course, the engagement groove 18 and the locking protrusion 19 are connected to the notch surface 16 extending in the length direction of the soft synthetic resin rail body 11.
17.

In this way, the soft synthetic resin rail main body 11 includes a thin inner shielding portion and a thicker outer shielding portion by a large number of voids 20 placed at appropriate intervals around the core material insertion hole portion 13. Therefore, the buffering effect is improved, and appropriate rigidity is maintained in the surface layer of the rail main body 11, so that it can be directly supported by the bracket 32.

Moreover, since the metal rail core material 12 is fitted into the inner shielding part, it is sufficient to extrude it to be thinner than the outer shielding part.

These voids 20 extend in the length direction and pass through the rail body 11, and their cross-sectional shapes can of course be modified in various ways as required.

On the other hand, the metal rail core material 12 is made of a steel pipe, but it goes without saying that this can be replaced with a solid rod.

In the top rail 10 constructed in this way, first, the metal rail core material 12 is fitted into the core material fitting hole 13 through the notch 14, and the metal rail core material 12 is fitted into the soft synthetic resin rail body 11. It is then attached to a plurality of washers 31 fixed to the wall surface 41 of the building 40 at appropriate intervals using the corresponding number of brackets 32, and end caps 33 are attached to both ends to form a handrail. Construct 30.

The end cap 33 is preferably made of soft synthetic resin, and can be attached to the top rail 10 by screwing a screw into the metal rail core 12 or by press-fitting a plug into the metal rail core 12. Fixed at both ends.

FIG. 4 shows a modified top rail 50 of this invention, in which the top rail 50 is constructed by dividing the metal rail core 12 in the top rail 10 shown in FIGS. 1 to 3, and This makes it easier to fit the soft synthetic resin rail body 11 into the core fitting hole 13.

That is, the metal rail core material 51 is constituted by a plurality of metal rail core materials 52 each having a unit length.

Therefore, components of this top rail 50 that correspond to other components of the top rail 10 that have not been deformed are given the same reference numerals, and their explanations are omitted.

FIG. 5 shows a wall-mounted handrail 70 using the top rail 60 of this invention, which is a further modification of the top rail 10 shown in FIGS. 1 to 3.

The top rail 60 in the wall-mounted handrail 70 is
The notch 14 of the soft synthetic resin rail body 11 of the top rail 10 is replaced with a bent notch 62, and the metal rail core 12 passes through the notch 62 into the core insertion hole 1.
3, using multiple wood screws 65,
The notch 62 is closed.

Also, like the soft synthetic resin rail body 11 of the top rail 10, this rail body 61 has joints 15 to be formed in the notch surfaces 63 and 64 of the notch portion 62, that is,
The engaging groove 18 and the locking protrusion 19 are omitted.

This top rail 60 is also made of extruded soft material in the same manner as the top rail 10! #, The metal rail core material 12 is fitted into the core material insertion hole 13 of the resin rail body 61 through the notch 62, the metal rail core material 12 is assembled to the soft synthetic resin rail body 61, and then the building It is attached to a plurality of fixed washers 31 at appropriate intervals on the wall surface 41 of 40 using the corresponding number of brackets 32, and end caps are attached to both ends, and the wall-mounted type handrail 70 is constructed. do.

Therefore, components of the top rail 60 that correspond to other components of the top rail 10 that were not deformed are given the same reference numerals, and their descriptions are omitted.

According to this invention, the soft synthetic resin rail body has a core insertion hole penetrated in the length direction, a thin inner shielding part around the core insertion hole, and a thin inner shielding part. a large number of voids spaced apart at appropriate intervals around the core material insertion hole portion and penetrated in the length direction so as to form a thick outer shielding portion at appropriate intervals in the radial direction; Furthermore, it is formed into a structure that extends in the length direction and has a notch that communicates with the core insertion hole and is formed from the inner shielding part to the outer shielding part, so it has an excellent cushioning effect. In addition, it is extremely easy to fit the metal rail core material, and the metal rail core material provides sufficient strength and rigidity.
The thick-walled outer shielding part maintains appropriate rigidity in the surface layer, and accordingly, the outer shielding part as the surface layer can be directly supported by the bracket, and the installation is easy on the structure and installation work. This makes it easier to use, reduces the number of parts, and allows for robust and inexpensive manufacturing. It also allows for continuous production of the rail body, and allows the continuous production to be rolled up, making it easier to pack and transport. It can be cut to any length at the installation location, and the metal rail core material can be replaced extremely easily, making it suitable for use in handrails, fences, guard rails, etc. It is particularly applicable to curved parts and corners of handrails, guard rails, etc., and its practicality is improved.
