Description

DETAILED DESCRIPTION OF THE INVENTION This invention consists of a handrail material made of a metal core covered with a thick tire layer, and is suitable for use in toilets, washrooms, etc. The present invention relates to a separate type joint used for handrails installed around various equipment in places such as bathrooms and other places.

Conventionally, this type of handrail has been made of stainless steel pipes, or synthetic resin coated pipes in which a steel pipe is coated with a thin layer of soft synthetic resin, and cheese-shaped joints have been mainly used for these handrails. Also, fittings have been used in which the bolt head is exposed on the upper surface of the handrail.

However, when these joints are used as means for connecting in a T-shape in a handrail using a handrail material made of a metal core covered with a tire layer, it is difficult to connect firmly, and in long-term use, It caused wobbling and was difficult to finish beautifully.

The purpose of this invention is to enable a strong T-shaped connection, enable long-term use without rattling, improve assembly workability on site, provide a beautiful assembly finish, and To provide a split type joint suitable for use in a handrail made of a handrail material in which a core material is covered with a tire layer.

In order to address these issues, the split type joint used in the handrail of the present invention has a seating surface that receives a handrail unit made of a handrail material including a metal core material and a tire layer formed on the surface of the core material on one side. a handrail receiver each having a female fitting on the other side, and fitting one end of the connecting unit so that the connecting unit made of the handrail material can be connected to the handrail unit in a T-shape, and A sleeve equipped with a male fitting at one end that fits into the female fitting, a screw receiving block fitted to one end of the connecting unit into which the sleeve is fitted, and a flanged caulking sleeve that passes through the handrail holder and the handrail unit. and a screw that passes through the handrail unit and the caulking sleeve, is screwed into the screw receiving block, caulks the caulking sleeve, and connects the handrail unit and the connecting unit in a T-shape. .

Hereinafter, preferred specific examples of the split type joint used in the handrail according to the present invention will be described with reference to the drawings.

1 to 4 show a specific example 10 of the split type joint of the present invention used in a handrail 25 installed around a Western-style toilet bowl 38 for a physically handicapped person in a toilet.

This joint 10 connects the handrail units 31, 31 and the connecting unit 32, and the handrail unit 31,
31 and mounting units 34, 34 respectively.
It is connected in a letter shape and is composed of a handrail receiver 11, a sleeve 15, a screw receiving block 18, a flanged crimping sleeve 19, and a screw 20.

The handrail receiver 11 is connected to the handrail units 31, 31.
A washer is equipped with a flat seat surface 12 on one side and a female fitting 13 on the other side, and a screw hole 14 penetrated at approximately the center of the seat surface 12.
It is equipped with

In this manner, the seat surface 12 of the handrail receiver 11 is formed flat, so that the crimping sleeve 19 can be easily and reliably crimped by tightening the screw 20.

The sleeve 15 is provided at one end with a male fitting 13 that is fitted into the female fitting 13 of the handrail receiver 11, and connects the handrail units 31, 31 and the connecting unit 32, and the handrail unit 3.
1, 31 and its mounting units 34, 34 are connected at both ends of the connecting unit 32 and its mounting units 34, 34, respectively, in a T-shape.
34, respectively.

The sleeve 15 also has a shoulder portion 17 for regulating the fitting position of the connecting unit 32 and the mounting units 34, 34 in the axial direction.
is provided inside.

The screw receiving block 18 is connected to the sleeve 1
5 are fitted into both ends of the connecting unit 32 and the upper ends of the mounting units 34, 34, respectively. Of course, the screw receiving block 18 is fixed to the units 32, 34, 34 by the dowel pins 24 in the fitted state to the units 32, 34, 34, respectively.

The crimping sleeve 19 has a flange 22 at one end and passes through the handrail receiver 11 and the handrail unit 31, as can be seen in FIGS. 3 and 4. That is, the caulking sleeve 1
9 passes through the screw hole 14 of the handrail receiver 11 and the screw hole 36 previously formed in the handrail unit 31.

The screw 20 passes through the handrail unit 31 and the caulking sleeve 19 and is screwed into the screw receiving block 18, and the head 2 of the screw 20 is screwed into the screw receiving block 18.
1 and the other end of the caulking sleeve 19, i.e.
While caulking the upper end, attach the handrail unit 31 to its connecting unit 32 and mounting unit 34,
34 in a T-shape.

Moreover, the above-mentioned handrail units 31, 31, connection unit 32, and mounting units 34, 34
As best understood from FIG. 2, the handrail material 36 that constitutes the handrail material 36 is made of a steel pipe 27 as a core material and a soft synthetic resin thickly extruded with an adhesive 28 interposed on the outer surface of the steel pipe 27. tire layer 29
and a hard synthetic resin skin layer 30 thinly extruded onto the surface of the tire layer 29 and covering the tire layer 29.

Next, to explain a method of connecting one handrail unit 31 and the mounting unit 34 corresponding to that handrail unit 31 in a T-shape using the above-mentioned joint 10, first, the mounting unit 3
A screw receiving block 18 is fitted inside the upper end of the mounting unit 34 and fixed with a dowel pin 24, and a sleeve 15 is fitted on the outer side of the upper end of the mounting unit 34.

Next, the seat surface 12 of the handrail receiver 11 is attached to the handrail unit 3 so that the screw hole 14 of the handrail receiver 11 is aligned with the screw hole 36 of the handrail unit 31.
1 skin layer 30, and the flanged caulking sleeve 19 is passed through the screw holes 14 and 36 from below.

Furthermore, the male fitting 16 of the sleeve 15 fitted to the upper end of the mounting unit 34 is fitted into the female fitting 13 of the handrail receiver 11, and in this state, the screw 20 is inserted into the handrail unit 31.
Pass through the caulking sleeve 19 from the through hole 35 side of the block 18 and screw it into the screw receiver into the block 18.
The handrail unit 31 is connected to the mounting unit 34 in a T-shape while caulking the upper end of the handrail unit 31. Of course, after the screw 20 is screwed in, the blind cap 26 is snapped into the through hole 35 of the handrail unit 31.

The above-mentioned method of using the joint 10 is for connecting one handrail unit 31 and the mounting unit 34, but for connecting the other handrail unit 31.
The connection of the mounting units 34 and the connection of the handrail units 31, 31 and the connection unit 33 are also carried out in the same manner as described above.

According to the above invention, a sleeve fitted on the outside of one end of the connecting unit is fitted into the handrail receiver having a seating surface for the handrail unit, and a screw receiving block is fitted on the inside of one end of the connecting unit. In addition, pass a flanged caulking sleeve through the handrail holder and the handrail unit, pass a screw through the handrail unit and the caulking sleeve, screw it into the screw receiving block, and screw the screw into the handrail unit while caulking the caulking sleeve. and the connecting unit are connected in a T-shape, and the handrail unit, handrail receiver, sleeve, screw receiving block, caulking sleeve, screw, and connecting unit are configured to be firmly integrated, so that the handrail can be connected in a T-shape. The T-shaped connection between the unit and the connecting unit is extremely strong, and such a strong connection can be maintained for a long time without wobbling. Since complicated installation work is not required, only screwing and screwing work is required, assembly work efficiency on site is improved.Furthermore, since the heads of the screws are not exposed, the assembly finish is beautiful and the metal It is suitable for use in handrails made of handrail materials made of core material covered with a tire layer, and is extremely practical.
