Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a support structure for a handrail cap used when fixing to a support base such as a wall of a handrail, and in particular, it is capable of reliably fixing the handrail cap. This relates to the support structure for handrail hats.

Recently, the safety and feel of the handrails made up of handrails have been highly evaluated, and various types of handrails have been proposed whose outer peripheral surfaces are coated with a covering material such as a soft synthetic resin.

However, in this case, as the outer circumferential surface of the handrail cap is covered with a covering material, even if an attempt was made to support it with brackets, it would not fit properly due to the elasticity of the covering material, so it was desired to support the handrail cap reliably. .

[Conventional technology]

FIG. 5 shows a conventional handrail support structure of this type.

In this conventional example, a receiving seat 4 for supporting the cap 3 of the handrail 2 is formed on the bracket 1, and after the cap 3 is placed on the receiving seat 4, it is fixed with an appropriate connector 5 such as a heat sink. .

[Problem that the invention seeks to solve]

However, in this conventional example, since the covering material 7 of the cap 3 is interposed between the receiving seat 4 of the bracket 1 and the core pipe 6 of the cap 3 as described above, for example, When a load is applied to the Kasagi 3, the above-mentioned receiving seat 4 and core pipe 6
The covering material 7 between the two was elastically deformed, and had a drawback that it was very difficult to sit on.

The present invention has been made in response to such circumstances, and an object of the present invention is to provide a support structure for a handrail cap that can easily and reliably fix the cap 3 of the handrail 2 to the bracket 1. do.

[Means for solving interlayer points]

In Figure 3, a support structure for a handrail hat corresponding to an embodiment of the present invention is shown.

The bracket l is fixed to a support base 8 such as a wall surface, and is adapted to support a handrail cap 3, which will be described later, on its receiving seat 4, and a communicating hole 9 is bored in this receiving seat 4. At the same time, the receiving surface of the receiving seat 4, that is, the communication hole 9
A protrusion IO is provided at the tip end of the IO so as to surround this communication hole 9.
is provided.

On the other hand, the cap 3 is formed by covering the outer surface of the core tube 6 with a covering material 7, and is intended to improve the feel or safety.

Then, an insertion hole 11 communicating with the communication hole 9 of the bracket 1 is bored in a part of the cap 3 corresponding to the receiving seat 4 of the bracket 1 through the covering material 7 and reaching the core pipe 6. Both are connected and fixed by a connector 5 inserted through the communication hole 9 and the insertion hole 11.

[Function] When the connector 5 is used to connect and fix the cap 3 and the bracket I, the protrusion 10 according to the present invention is inserted into the insertion hole 11 in the covering material 7 of the cap 3 as shown in FIG. The sheathing material 7 is pushed aside until it reaches the core pipe 6 of the cap 3, which enters into a wedge shape, and its tip abuts against the core pipe 6 of the cap 3.

Therefore, according to the conventional example, when the cap is placed and supported on the receiving seat 4 of the bracket I, the covering material 7 is interposed between the receiving seat 4 of the bracket I and the core pipe 6 of the cap 3. However, in the present invention, by bringing the protrusion 10 of the bracket I into contact with the core tube 6 of the cap 3, the swing of the cap 3 can be prevented. The cap 3 can be reliably supported by preventing this, and at the same time, troublesome work such as cutting off the covering material 7 can be omitted.

〔Example〕

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

1 and 2 show an example of a support structure for a handrail hat according to a first embodiment of the present invention.

In this embodiment, the bracket 1 is made of a metal such as an aluminum alloy or a zinc alloy, or a hard synthetic resin having a certain strength, and as shown in FIG.
A fixed part 1a fixed to a support base 8 such as a wall surface, and a cap 3
and an arm portion 1c that connects the fixing portion 1a and the holding portion 1b.The upper end of the holding portion 1b has an arcuate surface having approximately the same diameter as the outer circumference of the cap 3. is recessed to form a receiving seat 4.

A communicating hole 9 is vertically bored in the substantially central portion of the receiving seat 4, and a working hole 12, which is slightly larger than the communicating hole 9, is formed below the communicating hole 9.

Further, the projection 10 in this embodiment is integrally formed with the receiving seat 4 and has a substantially trapezoidal cross section, which improves the strength at its base end and the area of contact with the core tube 6 of the cap 3. It is planned.

On the other hand, the cap 3 in this embodiment is formed by coating the outer surface of a core tube 6 made of a steel pipe with a soft material such as a soft synthetic resin or synthetic rubber. An insertion hole 11 is bored through the core tube 6 to reach the core tube 6.

Therefore, in this case, the insertion hole 11 in the core tube 6 is threaded, and a screw or the like is used as the connector 5.

In addition to this, for example, when a simple insertion hole 11 is bored in the core tube 6, it is also possible to use a tapping screw as the connector 5.

Next, in order to fix the handrail 3 according to this embodiment using the bracket l, first, the insertion hole 1 is drilled on the back side of the cap 3.
1, and then touch the protrusion 10 of the bracket 1.
The connector 5 is tightened until the tip of the cap contacts the core tube 6 of the cap 3, thereby fixing the cap 3 and the bracket l.

Next, the bracket 1 is fixed to a support base 8 such as a wall surface at its fixed portion 1a, and the cap 3 is installed.

In FIG. 3, a second embodiment of the invention is shown.

This embodiment shows a case in which a protrusion 10 is formed separately from a receiving seat 4, and a bolt member 14.14 which is divided into two parts with a locking part 14a formed at its tip as a connector 5 is used. The communication hole 9 formed in the receiving seat 4 is formed to be slightly larger than the insertion hole 11 of the cap 3.
A protruding member 13 having a truncated cone shape is inserted therein.

On the other hand, a hole 13a is bored in the center of the protruding member 13, and bolt members 14 and 14, which are the connectors 5, are individually inserted into the hole 13a, and the bolt members By pulling 14 downward, the tip of the protrusion IO of the protrusion member 13 is brought into contact with the core tube 6 of the cap 3.

In addition, in the above-mentioned embodiment, the case where the bracket 1 and the capacitor 3 are connected using the screw or bolt-shaped connector 5 is shown, but the connector 5 is not limited to this, for example, It is also possible to use an anchor bolt 15 as shown in FIG. 4. In this case, after inserting the anchor bolt main body 15a through the communication hole 9 of the bracket 1 and the insertion hole 11 of the cap 3, the pin 15b is inserted into the anchor bolt. It is sufficient to insert the anchor bolt into the main body lsa, expand the stopper part 15c at the tip of the anchor bolt main body ISa to prevent it from being pulled out, and tighten the nut ISd to firmly fix it. Of course, it is not necessary to form them all around the communication hole 9, and they may be arranged at appropriate intervals.

〔Effect of the invention〕

As is clear from the above description, according to the support structure for the handrail cap according to the present invention, when a communicating hole is bored in the receiving seat of the bracket, the tip of the communicating hole is surrounded by a hole that surrounds the communicating hole. The protrusions were made to protrude as shown in the figure, and the handrail cap was provided with an insertion hole that communicated with the communication hole of the bracket all the way to the core tube. When connecting and fixing them, the covering material is pushed aside and inserted horizontally into the insertion hole in the covering material of the Kasagi until it reaches the core pipe of the Kasagi, and the tip thereof comes into contact with the core pipe of the Kasagi.

Therefore, by bringing the protrusion of the bracket into contact with the core pipe of the Kasagi, it is possible to prevent the Kasagi from swinging and to reliably support the Kasagi, thereby saving troublesome work such as cutting off the covering material when bracketing. (be able to.
