DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail used indoors and outdoors such as a corridor, stairs, a washroom, a toilet, a bathroom, and the like.

[0002]

2. Description of the Related Art Generally, steel pipes, aluminum alloy profiles, or
Handrails in which a core material obtained by roll forming a steel plate and coating a resin were only those having a single cross section. In addition, there was no handrail made of wood such as a single piece of wood or a laminated wood, which had irregularities continuously in the longitudinal direction.

[0003]

However, with the above handrail, the synthetic resin layer on the surface of the handrail member has no unevenness, so that it is easy to slip even when grasping, especially when the elderly with a weak gripping force tries to support the body with the handrail. The hand was slippery and dangerous. In particular, when using handrails vertically on stairs or bathrooms, it is difficult to support the body by slipping.

[0004]

This onset Akirago synthetic resin-made handrail SUMMARY OF THE INVENTION along the longitudinal direction on the surface of the elongated body cross-sectional shape of synthetic resin on the outer wall of the metal tube of the perfect circle are uniformly coated predetermined numerous protrusion Place the interval made and is projected in a row or a plurality rows irregularities, a plurality of cross-sectional shape of the recess synthetic resin on the outer wall of the metal tube is uniformly coated was made a perfect circle having the same diameter Handrail members
It is cut at the concave part, and the plurality of cut handrail members are
Connection member having a connection portion having a shape corresponding to the cross-sectional shape
And are formed continuously in the longitudinal direction.
The handrails and fingers are familiar with the handrails due to the unevenness
Hand is less slippery when the
It can be connected at any angle in its cross section direction.
Connection is easy, and the whole handrail has a sense of unity

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view showing an example of the embodiment of the present invention. 1 is a wall surface and 2 is a staircase. The handrail member 3 is mounted on the wall surface 1 via a mounting bracket 4. The end 31 of the handrail member 3 is connected to the end 31 of another handrail member 3 via the connecting member 5. FIG. 2 is a sectional view taken along the line AA of FIG. 1 showing the horizontal connection part A, and FIG. 3 is a sectional view taken along the line BB of the inclined connection part B of FIG. In the horizontal connection part a, handrail member 3
Is cut at the concave portion 32 and connected via the connecting member 5. Since the concave portion 32 of the handrail member 3 has a perfect circle of the same diameter at any position, the end 31 of the handrail member 3 cut by the concave portion 32 has a perfect circle of the same diameter, and a connection having the same diameter as the perfect circle. When connected via the connecting member 5 having the portion 51, the handrail as a whole has a sense of unity and looks good. Further, in the inclined connecting portion B, the handrail member 3 is cut at the concave portion 32 and connected via the connecting member 5 in the same manner as described above, so that the end portion 31 is formed as a perfect circle having the same diameter and the same diameter as the perfect circle. Even when the connecting member 5 having the connecting portion 51 is attached obliquely, the handrail member 3 and the connecting member 5 can be connected at a free angle about the center axis of the connecting portion 51 regardless of the inclination angle. Since the same connecting member 5 can be used for both the connection and the inclined connection, the number of members is small and the construction is easy. In this embodiment, the connecting portion 51 of the connecting member 5 is the end 31 of the handrail member 3.
However, the connecting portion 51 may have a similar shape slightly larger in diameter than the end portion 31 of the handrail member 3.

FIG. 4 is a partially cutaway front view showing an example of the embodiment of the handrail member 3 of the present invention. 33 is a core material,
Its surface is covered with a synthetic resin layer 34. The synthetic resin layer 34 is uniformly covered with the core material 33 to form the recess 32, thereby protecting the core material 33 from corrosion such as rust and improving the appearance. In addition, although the convex portions 35 are formed continuously in a row at predetermined intervals along the length direction of the synthetic resin layer 34 to form irregularities, a plurality of rows of irregularities may be formed. Also, the concave portion 32 is
3 is uniformly covered and the cross-sectional shape is a perfect circle.

As the core material 33, a metal pipe such as a steel pipe, an aluminum alloy pipe, or a stainless steel pipe is usually used. Further, in the above-described embodiment, the rust-preventing effect is obtained by the synthetic resin layer 34. However, the synthetic resin layer 34 may be subjected to plating or the like as a rust-preventive treatment of the core material 33, particularly in view of a design property. To be coated synthetic resin is generally polyvinyl chloride, PP, PE, although thermoplastic resins such as ABS is used, may be used thermosetting resin.

FIG. 5 is a cross-sectional view showing an example of an embodiment of the connecting portion between the handrail member 3 and the connecting member 5 of the handrail of the present invention. The shape of the end 31 of the handrail member 3 is a perfect circle. The connecting portion 51 of the connecting member 5 corresponding to the end portion 31 is also a perfect circle having the same diameter, and the leading end portion is inserted and fitted into the inner surface of the handrail member 3. Member 3
The connecting portion 51 may be slightly larger in diameter than the end portion 31 to cover the end portion 31. Since the end portion 31 of the handrail member 3 has a shape corresponding to the shape of the connection portion 51 of the connection member 5, the seam between the handrail member 3 and the connection member 5 has no unnatural feeling and has a sense of unity and has a good appearance.

[0009]

As described above, according to the present invention, the unevenness formed on the surface of the handrail member makes it difficult for the handrail to slip when gripping the handrail, and in particular, it is safe even for elderly people with weak gripping power without slipping. In particular, even when the handrail is used vertically on stairs, bathrooms, and the like, the hand can be supported by the unevenness of the handrail and the body can be safely supported without slipping. Also, there is no discomfort to the connection portion connecting be included in the inclined surface when the handrail is connected to several of the handrail member double, a handrail with a sense of unity. Further, the connection member can be used in common in both the horizontal plane and the inclined plane, so that the number of members can be reduced and the construction is easy.
