Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe holding method for a pipe handrail arranged in a slippery place such as a bathroom or a toilet.

[0002]

2. Description of the Related Art FIGS. 8 and 7 are enlarged horizontal cross-sectional views of a main portion of a conventional pipe handrail. In FIG. 8, 10 is a pipe handrail. It is composed of a pipe 13 made of. Further, reference numeral 12 is an engaging projection that projects from the support shaft 11 side at the connecting portion between the support 11 and the pipe 13.

Then, the pipe 13 is engaged so that the engaging projection 12 formed on the column 11 is inserted into the pipe 13, and the pipe 13 is fixed to the engaging projection 12 by the screw 14. This can be fixed to the column 11.

In FIG. 9, a female screw portion 13a is formed on the inner periphery of the end portion of the pipe 13 and a male screw portion 12a is formed on the outer periphery of the engaging projection 12, so that a separate member such as a screw 14 is formed. Without using the pipe 13
It is configured to be screwed into.

[0005]

However, in the conventional pipe holding method for the pipe handrail, in the structure as shown in FIG. 8, a hole is bored in the outer periphery of the pipe 13 and a screw 14 is formed in the hole. A separate member has to be screwed, which makes it unattractive. Therefore, the screw 14 must be installed in a position where it is inconspicuous as much as possible, and it is inevitably difficult to assemble the pipe handrail.

Further, with the configuration as shown in FIG. 9, it is very difficult to keep the screwing position of the pipe 13 with respect to the engaging projection 12 always in a constant phase. It cannot be fixed to the projection 12 by screwing, and a small gap is generated as shown in FIG. Therefore, in order to cover up this gap, a substantially cylindrical cover 16 is formed on the side of the column 11 to improve the appearance.

However, in the above structure, the cover 1
Dirt such as water stains entered between the pipe 6 and the pipe 13 to make it look unattractive, and because there was no means for fixing the rotation of the pipe 13, there was a danger in using it as a handrail.

The present invention has been made in consideration of the above points, and an object of the present invention is to provide a pipe holding method for a pipe handrail which has an extremely simple and good-looking structure and which can be easily attached. I am trying.

[0009]

That is, according to the present invention,
In a pipe handrail made by bridging a pipe between a pair of fixtures that erects a pillar from a wall surface, a tapered surface with a large diameter toward the inside of the pipe is formed on one end side, and a male screw part is formed on the other end side. Insert the formed fixing bracket into the pipe from one end side, and insert a split ring having an inner diameter that abuts the tapered surface of the fixing bracket and an outer diameter that is slightly smaller than the inner diameter of the pipe into the pipe. It is characterized in that the split ring is pressed against the inner circumference of the pipe by screwing the metal fitting and the support to fix the pipe to the support.

Further, a cut groove or an engaging hole for inserting a driver or a hexagon wrench may be formed at the other end of the fixing member. Further, a substantially cylindrical metal support fitting may be provided between the pillar and the split ring, and the circumference of the pillar may be covered with a protective cover made of a soft synthetic resin. In addition, an elastic body may be inserted into the contact portion between the split ring and the inner circumference of the pipe.

[0011]

According to the first aspect of the present invention, a fixing metal member having a tapered surface having a large diameter toward the inside of the pipe formed on one end side and a male screw portion formed on the other end side is provided in the pipe from the one end side. While inserting, a split ring having an inner diameter that abuts the tapered surface of the fixing bracket and an outer diameter slightly smaller than the inner diameter of the pipe is inserted into the pipe, and the split ring is piped by screwing the fixing bracket and the column. By fixing the pipe to the support by pressing it to the inner circumference, the pipe can be firmly fixed to the support without damaging the outside of the pipe by an extremely simple work of screwing the fixing metal, and A hygienic pipe handrail can be formed without any gaps between the pillar and the column.

When a screwdriver or a hexagon wrench is inserted into the cut groove or the engaging hole at the other end of the fixing member, the screwing operation of the fixing member can be performed very easily.

Further, when a substantially cylindrical metal support fitting is provided between the support column and the split ring and the periphery of the support column is covered with a protective cover made of a soft synthetic resin, the user has a pipe handrail. This is extremely useful as it eliminates the risk of injury from hitting the corners of the body.

In addition, when the elastic body is inserted in the contact portion between the split ring and the inner circumference of the pipe, the holding force of the pipe by the split ring is dramatically improved and the pipe handrail is stably engaged. To be done.

1 to 5 are views showing the structure of a pipe handrail and a method of holding the pipe, which is a first embodiment of the present invention. FIG. 1 is a horizontal sectional view, FIG. 2 is an exploded perspective view, and FIG. 4 is an enlarged view of a partial cross-section main part, and FIG. 5 is an overall view.

In FIGS. 1 to 5, reference numeral 1 denotes a pipe handrail, and the pipe handrail 1 is provided with a pair of fixing members 2 and 2 for vertically erecting a column 4 on which a pipe 3 made of, for example, stainless steel as a rust-resistant metal is installed. Is formed.

The fixing tool 2 has a flat fixing portion 4a fixed to the wall surface at one end, a substantially cylindrical support 4 having a holding flat surface 4b and a screw hole 4c at the other end, and a pipe 3 at one end. A fixing metal fitting 5 having a taper surface 5a having a large diameter toward the inside, a male screw portion 5b and a driver fitting cut groove 5c on the other end side, an inner diameter circumscribing the taper surface 5a and an inner diameter A of the pipe 3. (See FIG. 3) Split ring 6 having an outer diameter B slightly smaller than that, and holding surface 4b of the column 4.
A support member 7 having a substantially cylindrical shape having one end that abuts on the side of the split ring 6 and the other end that abuts on the side of the split ring 6, and a protective cover 8 made of a soft resin that covers the outer periphery of the support column 4.

The pillar 4, the fixing bracket 5, the split ring 6,
The support fittings 7 are all made of metal, for example, the support pillar 4 is made of brass casting, and the fixing fitting 5, the split ring 6, and the support fitting 7 are made of brass.

The protective cover 8 has a shape of a substantially cylindrical column cover 8a formed of an elastomer as an example of a soft resin, a shape of a flat plane cover 8b for covering the fixing portion 4a of the column 4, and a support shaft. Of the openings 8c and 8d provided at one end of the cover 8a, there is a sealing plug 8e for sealing the opening 8d to which the pipe 3 is not attached.

Next, a method of holding the pipe 3 of the pipe handrail 1 will be described. Referring particularly to FIG. 2, the fixture 5, the split ring 6, and the support 7 of the fixture 2 are inserted into the pipe 3 in this order, and the male screw portion 5b formed on the other end of the fixture 5 is attached to the pipe 3. Project from the end of. Then, the pillar 4 is covered with the pillar cover 8a and the plane cover 8b so that the opening 8c is located on the holding surface 4b, and the male screw portion 5b of the fixing metal fitting 5 is screwed into the screw hole 4c of the pillar 4. To do.

FIG. 3 shows an enlarged cross-sectional view of a main part of the pipe handrail 1 before being assembled. In this state, the outer diameter B of the split ring 6 is slightly smaller than the inner diameter A of the pipe 3, as described in detail above. That is, in this state, the pipe 3 can be easily attached and detached. Therefore, in this state, the pipe 3 is attached to the column cover 8a.
The fixing member 5 is screwed forward by engaging a driver or the like with the cut groove 5c formed on the other end side of the fixing member 5 so that the fixing member 5 comes into contact with the fixing member 5.

At this time, the fixing member 5 is attached to the arrow C in FIG.
The taper surface 5a formed on one end side expands the diameter of the split ring 6 in the direction indicated by the arrow D. FIG. 4 shows the assembled state of the pipe handrail 1 by an enlarged cross-sectional view of the main part. That is, the pipe 3 can be firmly fixed to the column 4 through the split ring 6 and the fixing metal 5 by sufficiently tightening the fixing metal 5. Finally, the opening 8d may be sealed with the sealing plug 8e.

Further, the inclination angle α of the tapered surface 5a of the fixing member 5 can be set as appropriate, but by reducing the inclination angle α, the pipe 3 can be strongly held with less force. As described above, since the holding force of the pipe 3 is strengthened by increasing the diameter of the split ring 6 using the taper surface 5a of the fixing fitting 5, the pipe 3 can be more stably attached to the column 4. Since the rotation and wobbling of the pipe 3 with respect to the support column 4 do not occur, the user does not feel uneasy.

According to the pipe handrail 1 constructed as described above, there is no need to fix it from the outer periphery of the pipe 3 with screws or the like. Therefore, as shown in FIG. Not only does it look good with no gaps between it, it is hygienic as it does not contain dirt such as water stains. Further, since the fixture 2 is entirely covered with the protective cover 8 made of a soft resin and the end of the pipe 3 is in contact with the protective cover 8, there is a risk that the user may hit the pipe handrail 1 and be injured. There is no, and it is safe.

In the above-mentioned embodiment, the safety is improved by covering the fixture 2 entirely with the protective cover 8 made of soft resin. However, the protective cover 8 may be omitted. In that case, the manufacturing cost can be reduced by omitting the support metal fittings 7.

FIGS. 6 and 7 show a second embodiment of the present invention, FIG. 6 is an exploded perspective view of a main portion thereof, and FIG. 7 is a horizontal sectional view. In these drawings, the components denoted by the same reference numerals as those in FIGS. 1 to 5 are the same or equivalent members, and thus detailed description thereof will be omitted. In addition, other configurations are shown in FIG.
It is the same as 5, so it is not shown.

In these figures, 6a is a split ring 6
It is an elastic body that comes into contact with the outer periphery of, and is, for example, a ring body made of synthetic rubber. As shown in FIG. 7, the ring body 6a is inserted into the contact portion between the pipe 3 and the split ring 6 to increase the frictional resistance between the split ring 6 and the pipe 3. Therefore, the pipe 3 can be more strongly held according to the increase in the diameter of the split ring 6,
The engagement of the pipe handrail becomes more stable.

Further, 7a and 7b are ring-shaped elastic flat plates made of synthetic rubber, and abut on both ends of the support fitting 7, respectively. That is, the elastic flat plates 7a and 7b are connected to the support 4
And the supporting ring 7 and the split ring 6 with respect to the support column 4 by interposing it in the joint portion with the split ring 6.
So that it will not rotate.

Therefore, when the fixing metal fitting 5 is screwed to fix the pipe 3 to the support shaft 4, the rotation of the fixing metal fitting 5 causes the split ring 6 to rotate, and as a result, the pipe 3 rotates. As a result, the work of assembling the pipe handrail becomes simpler.

Further, in this embodiment, the cut groove 5c is formed on the other end side of the fixing member 5, but an engaging hole for fitting a hexagon wrench may be formed instead. It goes without saying that it is good.

[0031]

As described above, in the pipe holding method for a pipe handrail according to the present invention, a tapered surface having a large diameter toward the inside of the pipe is formed on one end side, and a male screw portion is formed on the other end side. The fixing metal fitting is inserted into the pipe from one end side thereof, and a split ring having an inner diameter that abuts the tapered surface of the fixing metal fitting and an outer diameter slightly smaller than the inner diameter of the pipe is inserted into the pipe. The split ring is pressed against the inner circumference of the pipe by screwing with the column to fix the pipe to the column, and the extremely simple work of screwing the fixing bracket allows the pipe to be protected without damaging the outside of the pipe. Can be firmly fixed to the column. Therefore, when the pipe is grabbed, it does not wobble or rotate and is always stable, so that the user does not feel uneasy.

Further, since there is no gap between the pipe and the support, not only does it look good, but dirt such as water stains does not enter through unnecessary gaps, and a sanitary pipe handrail is always used. Can be formed.

Further, when a cutting groove or an engaging hole for inserting a screwdriver or a hexagon wrench is formed at the other end of the fixing metal fitting, the screwing operation of the fixing metal fitting can be performed more easily. The property is improved.

Further, in the case where a substantially cylindrical metal support fitting is provided between the support and the split ring, and the periphery of the support is covered with a protective cover made of soft synthetic resin, the user can use a pipe handrail. Even if you hit the corner of the body,
It is extremely safe because there is no risk of serious injury.

In addition, when an elastic body is inserted in the contact portion between the split ring and the inner circumference of the pipe, the holding force of the pipe by the split ring is dramatically improved and the pipe handrail is stably engaged. To be done.
