DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail assembly structure. More specifically, the invention of this application relates to a handrail assembly structure installed outdoors or the like.

[0002]

2. Description of the Related Art Conventionally, handrails for ensuring safety, especially for elderly people and children, have been installed on outdoor walking paths and the like. From the viewpoint of weather resistance and the like, a handrail body made of a metal such as stainless steel, steel, or aluminum is generally attached to an upper end of a column or the like.

However, in the case of such a metal handrail main body, there was an unpleasant sensation that it was hot in summer and cold in winter. On the other hand, when a non-metallic handrail body such as wood or resin is used, since the thermal conductivity is lower than that of a metal handrail body, discomfort such as hot and cold feelings is reduced. However, there is a problem in terms of durability, and there is a disadvantage that warpage and cracks are easily generated.

Accordingly, the applicants of the present application have provided a new handrail in which a non-metallic handrail body is attached and integrated with a reinforcing shed (Japanese Patent Application Laid-Open No. 9-317113. Requested invention "). As shown in FIG. 4, the handrail according to the prior application of the present invention includes a non-metal handrail main body (1) made of wood, resin, or the like, and a reinforcing shed (2) made of metal, resin, or the like screwed to the bottom. The handrail members are sequentially connected to each other and attached to a support (4) or the like.

That is, in the case of the handrail of the invention of the prior application, since the handrail body (1) is made of a non-metallic material, it does not cause discomfort such as a hot sensation or a cold sensation. Since the strength is reinforced by 2) and the durability is improved, the handrail body (1) is prevented from warping or cracking.

[0006]

The handrail of the invention of the prior application proposed by the applicant of the present application has the above-mentioned excellent characteristics, but points to be further improved by the subsequent study. Was found. That is, in the handrail of the invention of the prior application, the handrail main body (1) is connected by abutting the end faces of each other, but a gap is provided between the reinforcing caps (2) that are easily expanded and contracted by heat, humidity change, and the like. This gap absorbs the extension of the reinforcing shed (2). When the handrail body (1) and the reinforced shed (2) are brought into contact with each other, the reinforced shed (2) can be freely contracted to some extent, for example, as shown in FIG. The long hole for the fixing member formed in (2) (5)
The fixing member (3) is inserted through and fixed to the fixing member.

However, when the fixing member (3) such as a screw is inserted into and fixed to the long hole (5), the fixing member (3) may be offset to one of the long holes (5). . In such a case, as illustrated in FIG. 6, the reinforced shed (2A) (2B)
When the elongates or contracts in the opposite direction, the reinforced shed
A gap larger than the original gap (D) is generated between (2B) and a gap may also be generated in the handrail body (1). Further, when the reinforcing caps (2A) and (2B) extend in the opposite directions, the extension dimensions cannot be absorbed even by the gap (D) provided therebetween, and the reinforcing caps (2A) and (2B) cannot be absorbed by the contact pressure. Problems such as deformation of 2) have occurred.

For this reason, there is a need for an improvement in the prior application invention in order to efficiently absorb the expansion and contraction of the reinforcing shed due to changes in heat and humidity. The invention of this application has been made in view of the circumstances described above, and further improves the invention of the prior application, and suppresses a change in a gap caused by expansion and contraction of a reinforcing shed due to a change in heat, humidity, and the like. It is an object of the present invention to provide a new handrail assembly structure that does not cause a gap therebetween and has excellent durability.

[0009]

The present invention solves the above-mentioned problem by providing a non-metallic handrail main body and a reinforcing cap, and the bottom of the handrail main body and the reinforcing cap are fixed by a fixing member. In the handrail that is being attached, a plurality of holes for inserting a fixing member are formed in the longitudinal direction of the reinforcing shed that contacts the bottom of the handrail body, and the hole at the center position has a diameter equal to the diameter of the fixing member. The other hole is a long hole, and after the fixing member is inserted and fixed in the round hole at the center position, the fixing member is inserted and fixed in the other long hole. To provide an assembly structure of a slide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

[0011]

FIG. 1 is an exploded perspective view showing an embodiment of the present invention. As exemplified in FIG. 1, in the handrail assembly structure of the present invention, similarly to the prior application, a nonmetal handrail body (1) made of wood, resin, or the like, and the handrail body (1) are used. ) Different material (for example, metal such as stainless steel, steel, aluminum, or resin)
(2) made of the above is integrated with a fixing member (3) such as a screw or a screw. And, by attaching the reinforcing hood (2) to a column or the like, a handrail is erected.

A plurality of holes (5) for inserting a fixing member are formed in the reinforcing shed (2) in the longitudinal direction, and a hole at the center position is a round hole (equal to the diameter of the fixing member (3)). 51) and the other hole is a long hole (5). After the fixing member (3) is inserted and fixed in the round hole (51), the fixing member (3) is sequentially inserted into the other long hole (5). ) Is inserted and fixed.

In the case of the handrail according to the present invention having such an assembly structure, the center position of the reinforcing shed (2) is fixed by a fixing member (3) inserted through and fixed to the round hole (51).
It is fixed at a point, and this center position does not move even if it expands and contracts due to changes in heat and humidity. Therefore, for example, as illustrated in FIG.
In the case where B) are mutually extended, the extension range is from the center position to the end, and the extension dimension is at most 1/2 as compared with the case where the full length of the reinforcing shed is extended as in the prior application. Thus, each extension dimension can be sufficiently absorbed by the gap (D) set in advance between the reinforcing sheds (2A) and (2B).

Further, as shown in FIG. 3, even when the adjacent reinforcing caps (2A) and (2B) contract each other, the range of contraction is from the center position to the end.
Therefore, as shown in FIG. 6, the width of the gap (D) between the reinforcing caps (2A) and (2B) is 1 / compared to the case of the prior application in which the total length of the reinforcing caps extends or contracts. 2 or less, and no gap is formed in the handrail body (1).

Of course, the invention of this application is not limited to the above examples, and it goes without saying that various aspects of the detailed configuration and the like are possible.

[0016]

As described in detail above, according to the invention of this application, the change in the gap caused by the expansion and contraction of the reinforcing shed due to the change in heat and humidity is reduced, and no gap is formed between the handrail bodies. A new handrail assembly structure with excellent performance is provided.
