Description

The present invention relates to a handrail . More specifically, the present invention relates to ceramics that can be used as building materials. In addition, the present invention relates to a product that has a texture that has never been seen so that it can be differentiated from existing handrails. Further, the present invention relates to a device that has excellent weather resistance even when installed outdoors.

  In many cases, handrails are provided on the wall surfaces of places where people stand and sit (for example, bathrooms, toilets, etc.) to assist operation. Such a handrail has a structure in which an attachment for attaching to a wall surface is provided at an end portion of a bar-shaped handrail structure including a straight portion and a curved portion. In recent years, many buildings are built with the idea of barrier-free, and the demand for handrails is increasing.

However, the conventional handrail as described above has the following problems.
Conventional handrails are generally manufactured by combining materials such as wood, metal, and synthetic resin alone or in combination, and have not been novel in terms of material texture. In addition, handrails tend to be limited in shape variations even from their applications. For this reason, it has been difficult to differentiate handrails in terms of appearance.

  In addition, since the handrail is manufactured with the above-mentioned materials, for example, when installed outdoors, it may decay, rust (oxidize), deteriorate due to sunlight, sea breeze, etc. (weather resistance is not good) It was easy to do.

  The present inventor is involved in the development of handrails, and for the reasons described above, it can be differentiated in appearance as compared with conventional ones, and has a unique characteristic that is excellent in corrosion resistance and weather resistance. I was researching whether it could not be handrailed.

  Thus, the present inventor has paid attention to ceramics (a fired product of ceramics, ceramics, etc. (including ceramics)) as a material constituting the handrail. However, there is a problem that ceramics are easily cracked when hit or dropped.

Therefore, the present inventor conducted various experiments to solve the above problems. As a result, if a hollow part is formed in the ceramic, a core material having a required strength is provided therein, and the filling is solidified, the filling and the ceramic can be brought into close contact with each other. I got the idea that handrails that are hard to break even when ceramics are used for the exterior.
The present invention has been completed based on the above idea.

An object of the present invention is to enable ceramics to be used as building materials.
Another object of the present invention is to provide a tube structure capable of differentiating from an existing handrail so as to have an unprecedented texture, and a handrail using the tube structure.
Another object of the present invention is to provide a pipe structure having excellent weather resistance even when installed outdoors and a handrail using the same.

Means taken by the present invention to achieve the above object are as follows.
In the first invention,
A core material having a required strength is passed through the hollow part of the ceramic pipe or porcelain pipe, and the hollow part is in close contact with or substantially in close contact with the inner surface of the hollow part in a state where the filling is solidified. It is filled so as to
It is a tube structure.

In the second invention,
The core material is characterized by comprising a linear body and a spacer that allows the linear body to pass through the central portion of the hollow portion or a position that is substantially the central portion.

It is a handrail.

  The core material can be provided in a continuous state over the entire length of the hollow portion of the ceramic tube or porcelain tube, or can be provided in an intermittent state. Moreover, what has rigidity and what has flexibility or a deformability can be used for a core material.

  Examples of the decoration provided on the surface of the pottery tube or the porcelain tube include painting. In this specification, the term “painting” is used as a concept that includes not only coloring with paints, glazes, etc., but also coloring with printing (printing) or stickers.

  The pipe structure according to the present invention can be used for various purposes such as railings, fences, veranda frames, door handles, frame materials such as paintings and signboards, pillar materials, various decorative materials, etc. in addition to handrails. Can be used.

  The filling material to be filled in the hollow portion is not particularly limited, and for example, mortar, synthetic resin, natural resin and the like can be used. Of these, synthetic resins and natural resins that can be solidified in a transparent state can be used, for example. In this case, the tube structure can be made to shine by using a ceramic tube or a porcelain tube having translucency, and further placing a light emitter in the hollow portion. Such a tube structure can be used like illumination or as a guide light.

(Work)
The tube structure and the handrail according to the present invention are filled so that a core material having a required strength is passed through a hollow portion of a ceramic tube or a porcelain tube, and is then in close contact with or substantially in close contact with the inner surface of the hollow portion. It is manufactured by filling and solidifying. Since the tube structure has such a structure, it is difficult to break even when ceramic or porcelain is used as the material. Moreover, even if a ceramic tube or a porcelain tube is broken, a core material is provided and connected by this, so it is not destroyed immediately.

  The core material is configured to include a linear body and a spacer that passes through a position where the linear body is a central portion of the hollow portion or a substantially central portion. It can pass through the hollow part with which a ceramic pipe or a porcelain pipe is provided, and can arrange | position in the position which passes through the approximate center part in the said hollow part.

  If the surface of a ceramic pipe or porcelain tube is decorated, design can be imparted to the ceramic pipe or porcelain pipe.

  If a pottery tube or a porcelain tube is provided with heating means, the pottery tube or porcelain tube can be heated or cooled.

The present invention has the above-described configuration and has the following effects.

(Work)
The operation of the handrail T1 shown in the present embodiment will be described with reference to FIGS.
The handrail T1 is formed using a porcelain tube 10 made of porcelain, so it has a unique texture and texture not found in conventional wooden, metal, and synthetic resin products, and has a novel appearance. Differentiation can be achieved. Further, since the outer surface of the porcelain tube 10 is decorated by painting, it is possible to impart design properties.

  Porcelain has properties such as corrosion resistance, light resistance, and chemical resistance. Therefore, the handrail T1 also has weather resistance such as corrosion resistance, light resistance, chemical resistance, and the quality does not deteriorate for a long time even when installed outdoors, for example. As a result, the handrail T1 can be installed without any trouble even in places such as hot springs and the seaside, which have been considered difficult to install for a long period of time with metal or the like.

  Since the core material 11 is embedded in the interior of the porcelain tube 10, the handrail T1 is not broken even when the porcelain tube 10 or the mortar 12 is broken by an impact, for example, and does not fall off in use.

  Moreover, the handrail T1 which became unnecessary can also crush the porcelain tube 10 and the mortar 12, and if these are crushed, the embedded core material 11 can also be taken out easily. That is, the handrail T1 can be easily separated into an inorganic material composed of the mortar 12 and the porcelain tube 10 and the metal constituting the core material 11, and can be discarded in an easily recyclable state.

FIG. 3 is a perspective explanatory view showing a second embodiment of the handrail according to the present invention,
4 is a cross-sectional explanatory view showing an end side of the handrail shown in FIG.
FIG. 5 is a perspective explanatory view showing a part of the core material arranged in the tube body.
3 to 5, the same or equivalent parts as those shown in FIGS. 1 and 2 are denoted by the same reference numerals. Further, in the following description, the description overlapping with the above-described part of the structure is omitted except for necessary matters.

The handrail T2 includes a tube structure 1a and fixtures 2 and 2.
The tube structure 1a includes a porcelain tube 10a having a curved portion (arc portion) and having a so-called waveform shape.

  A metal core 11a is provided through the porcelain tube 10a. The core material 11a is formed in a substantially “ten” shape so that the wire 110a, which is a linear body having a required tensile strength, and the wire 110a are arranged at a position passing through a substantially central portion in the porcelain tube 10a. A spacer 111 and a spiral body 112 formed by winding a wire in a coil shape at a required pitch and having a diameter slightly smaller than the inner diameter of the porcelain tube 10 are provided.

  The core material 11a is formed by inserting a wire 110a through a spiral body 112 having substantially the same length as the porcelain tube 10a and interposing a spacer 111 between the spiral body 112 and the wire 110a. The spiral body 112 is combined so as to be disposed at a position passing through a substantially central portion. Specifically, the spacer 111 is combined by welding the vicinity of the intersection to the wire 110 a and welding the four end portions to corresponding portions of the spiral body 112. The spacers 111 are attached at a required pitch in the length direction of the wire 110a.

  When the core material 11a is put in the porcelain tube 10a in a combined state, the outer side of the spiral body 112 substantially hits the inner surface of the porcelain tube 10a, so that the wire 110a can be connected to the porcelain tube 10a having a curved portion. It arrange | positions in the position which passes along the approximate center part in the ceramic tube 10a.

The fitting part 200 of the fixing member 20 is attached to both ends of the tube structure 1a. The fixing member 20 is formed by passing a wire 110a through a through-hole 203 formed in the back wall portion 205 of the fitting portion 200, and pulling the synthetic resin washer W2 and a caulking tool K on the opposite side of the back wall portion 205 in a pulled state. Is fixed to the end of the pipe structure 1a.

(Work)
In the handrail T2, the core member 11a is formed by passing the wire 110a through the inside of the spiral body 112 and interposing the spacer 111 between the spiral body 112 and the wire 110a, and passing through the substantially central portion of the spiral body 112. Since the wire 110a is arranged, even if the outer side of the spiral body 112 substantially hits the inner surface of the porcelain tube 10a by being put in the porcelain tube 10a, the porcelain tube 10a having a curved portion can thereby be obtained. The wire 110a can be arrange | positioned in the position which passes along the approximate center part in the porcelain tube 10a. Therefore, the handrail T2 can be provided with a substantially uniform strength over the entire length (the strength is not easily biased).

  In the above embodiment, the fixing member 20 and the decorative cover 21 constituting the fixing metal fitting 2 are both cast products, and the ones plated on the whole to prevent corrosion are used. However, the fixture is not limited to this, and for example, wood, synthetic resin, ceramics, or the like can be used.

  In the above-described embodiment, the mortar 12 is filled in the porcelain tube 10 (10a). However, this is not a limitation, and if it can solidify after filling and adhere to the inner surface of the porcelain tube 10 (10a), For example, a synthetic resin or a natural resin can be used.

  Although not provided in the handrails T1 and T2 shown in the above embodiment, it is possible to separately provide heat generating means inside the porcelain tube 10 (10a). By providing the heat generating means, it is possible to warm or cool the tube structure 1, and it is possible to improve the usability of the handrail T1 in winter and summer. In the case of heating, the heating means can be configured by, for example, incorporating a heating element such as a nichrome wire, or by causing the core material to generate heat through electricity. Further, the heat generating means can be provided over the entire length of the porcelain tube 10 (10a) or can be provided partially.

  In the handrails T1 and T2 shown in the above embodiment, for example, a photocatalyst (for example, titanium oxide) can be provided on the surface, thereby providing a deodorizing effect, an antifouling effect, an antibacterial effect, and the like. is there. These effects can also be imparted by means other than the photocatalyst. Handrails having such effects are improved in adaptability in places such as hospitals and welfare facilities.
