It is related with the coupling member which can be utilized for.
[0002]
[Prior art]
In general, handrails with different orientations are connected to each other at a connecting portion such as a corner where the direction of the handrail changes by using a joint member capable of adjusting the angle. Conventionally, such joint members are disclosed in JP-A-5-148968, JP-A-6-173407, JP-A-7-324523, JP-A-10-169142, JP-A-2-138296, JP-A-5-7806, and the like. Various forms have been proposed.
[0003]
In JP-A-10-31127, JP-A-11-107478, JP-A-2000-170341 and the like, a metal core material made of synthetic resin is used for the purpose of improving the appearance and imparting a non-slip effect to the handrail. The handrail which coat | covered this cover member is disclosed, and the trial which provides a cover member similarly to the joint member of a corner is made | formed.
[0004]
[Problems to be solved by the invention]
However, when the cover member is provided on the joint member, if the joint member is bent and used, the inner portion of the core material becomes shorter, so that the cover member located on the inner side is wrinkled, which is not preferable in terms of appearance. It was.
[0005]
An object of the present invention is to provide a joint member such as a handrail that prevents the cover member from being wrinkled even when the joint member is folded and used by allowing the cover member to move on the core material. And
[0006]
[Means for Solving the Problems]
A joint member such as a handrail according to the present invention includes a bendable core member, a connecting member connected to a handrail provided on both sides of the core member, a shorter member than the core member, and a periphery of the core member. A surrounding flexible cover member, and a ring member provided with a space around the core material at both ends of the core material, the diameter of the space portion covering the outer diameter of the core material The cover member is formed to have a diameter larger than the diameter of the member, and both end portions of the cover member are inserted into the space portion, and the end portions of the cover member are movable in the space portion .
[0007]
In the joint member such as the handrail of the present invention, the core material is bent at an arbitrary angle according to the situation at the construction site, and ends of the handrail and the like having different directions are integrally connected to the connecting member. The cover member covers the core material and prevents the core material from being exposed to the outside. When the core material is bent, the length of the inner part of the core material is shortened, so the cover member will be displaced in the axial direction as it goes inward, but the space formed by the ring member is displaced by this cover member. The wrinkles are absorbed (the cover member moves in the space) and no wrinkles occur.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The core material used in the joint member of the present invention is not particularly limited as long as it has a foldable structure, and a conventionally known structure can be used. For example, there is a structure in which a large number of notches are formed on one side portion of the core material and can be bent so that the side on which the notches are provided is inside.
[0009]
The cover member is not particularly limited as long as it is flexible and can be deformed following the bending of the core material. However, the cover member is preferably formed of a material having good weather resistance, flame retardancy, and the like. For example, it is preferable to use a resin cover member made of an olefinic thermoplastic elastomer such as ethylene propylene rubber. Moreover, it is also preferable to employ a means that can smoothly move the upper surface of the core material when the core material is bent.
[0010]
If the said ring member can form the space part of a predetermined | prescribed magnitude | size, the structure and material will not be specifically limited. The ring member may be formed integrally with the core material, or may be formed separately and fixed to the core material. In addition, it is preferable to form a protrusion on the inner surface of the ring member that abuts on both ends of the cover member to restrict movement. By forming the protrusion, the cover member can be fixed at a predetermined position, and the cover member can be prevented from being displaced to one side and coming out of the space portion.
[0011]
The space portion only needs to be large enough to move the cover member, and long enough to accommodate the slack of the cover member that occurs in the inner portion of the core when the core member is bent.
[0012]
The connecting member is not particularly limited as long as it can be connected to a handrail or the like, and a conventionally known structure can be used. Moreover, the joint member of this invention can be used for the connection of the handrail in a corner and the trunk edge of a fence.
