[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a handrail connection structure.

[0002]

2. Description of the Related Art A conventional handrail connection structure includes a tubular handrail body and a joint member having a pair of arms formed on both side surfaces of a flange. In this case, the pair of handrail main bodies are fitted to the pair of arm portions of the joint member and the edge portions thereof are brought into contact with the flange.

[0003]

However, a gap may occur at the joint between the edge of the handrail body and the flange, resulting in deterioration of the appearance. In addition, rainwater and the like sometimes enter the handrail body through the gap. further,
Since the edge of the handrail body is exposed, if the handrail body was cut on site, there was a risk of injury from a small edge.

Therefore, an object of the present invention is to provide a handrail connecting structure which has an improved appearance and prevents water from entering the body of the handrail and which is highly safe.

[0005]

SUMMARY OF THE INVENTION A handrail connection structure of the present invention comprises a tubular handrail main body having a pair of protrusions formed on the lower surface in the width direction, and abutting on both sides of the inner peripheral surface of the handrail main body. Possible
Horizontal piece and on the inner peripheral surface of the handrail body orthogonal to this horizontal piece
The arm consisting of a vertical piece that can abut the lower part
A joint member formed on each of the side surfaces and a joint cover made of a substantially C-shaped elastic material having concave locking portions formed on both ends are provided, and the pair of handrail main bodies are fitted to the pair of arm portions of the joint member. The edge portions of the pair of handrail main bodies and the flanges and the edge portions of the handrail main body so that the edge portions of the handrail body and the flange are in close contact with each other. It is characterized by being locked to.

[0006]

According to the structure of the present invention, since the joint edge portion of the handrail main body and the joint portion of the flange of the joint member are covered with the joint cover, no gap is generated and the external appearance can be improved. Further, along with this, it is possible to prevent water from entering the inside of the handrail main body. Further, even when the handrail main body is cut in the field, the edge is covered with the joint cover, so there is no risk of injury. Further, since this joint cover can be elastically deformed and expanded to be attached to the joint portion later, it can be applied to the conventional handrail connection structure. At the time of attachment, the engaging portion of the joint cover is engaged with the protruding portion of the handrail main body, so that the attachment can be performed easily and reliably. Also, the joint cover is a flange
And a pair of handrails to cover the edges of the body so that they are in close contact.
Therefore, if the flange protrudes from the handrail body,
No rain between the joint cover and the handrail body
Water does not enter. In addition, the joint member
The arms formed on both sides of the lunge are
A horizontal piece that can contact both sides of the inner peripheral surface and orthogonal to this horizontal piece
From vertical pieces that can come into contact with the upper and lower parts of the inner surface of the handrail body
Since it has a different shape, the shape should be along the inner peripheral surface of the handrail body.
Compared to the case, the handrail body can be easily fitted to the arm.
And the workability is improved. Also, this joint member
The horizontal piece touches both sides of the inner peripheral surface of the handrail body,
If the piece contacts the upper and lower parts of the inner peripheral surface of the handrail body,
Therefore, it is possible to handle handrails with different shapes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A handrail connection structure of a first embodiment of the present invention will be described with reference to FIGS. This handrail connection structure includes a handrail main body 1, a joint member 2, and a joint cover 3. As shown in FIG. 3, the handrail main body 1 is tubular and has a pair of protrusions 4 and 4 formed on the lower surface in the width direction. Further, a fastener insertion hole 5 is provided in the central portion of the lower surface.

As shown in FIGS. 4 to 6, the joint member 2 has a pair of arm portions 7, 7 formed on both side surfaces of the flange 6. The arms 7 are provided on both sides of the inner peripheral surface of the handrail main body 1.
The horizontal piece 7a that can come into contact with the
A vertical piece 7b that can come into contact with the upper and lower parts of the inner peripheral surface of the handrail body 1;
The handrail body 1 is internally fitted. A projection 8 having a hole into which the tapping screw 10 is screwed is formed at a position of the horizontal piece 7a corresponding to the fastener insertion hole 5.

The joint cover 3 is formed of a substantially C-shaped elastic material, and has concave locking portions 9 and 9 which can be locked to the pair of projections 4 and 4 at both ends. The joint cover 3 is formed so as to cover the flange 6 and the edge portions of the pair of handrail main bodies 1, 1 and to be in close contact with these members when the pair of handrail main bodies 1, 1 are joined by the joint member 2. To be done.

Next, the construction procedure will be described.
That is, the handrail main body 1 is fitted to the arm portion 7 of the joint member 2, and the edge portion of the handrail main body 1 is brought into contact with the flange 6.
The tapping screw 10 is passed through the fastener insertion hole 5 and screwed into the protrusion 8. Then, as shown in FIGS. 1 and 2, the joint cover 3 is put on the joint between the edge portion of the handrail main body 1 and the flange 6 of the joint member 2. In this case, the joint cover 3 is elastically deformed to expand and the locking portions 9, 9 are
Is attached to the protrusions 4 and 4 of the handrail main body 1 by attaching.

In this embodiment, the joint cover 3 covers the joint between the edge of the handrail main body 1 and the flange 6 of the joint member 2, so that there is no gap and the appearance can be improved. Further, along with this, it is possible to prevent water from entering the inside of the handrail main body 1. Further, even when the handrail main body 1 is cut on site, the edge is covered with the joint cover 3, so there is no risk of injury. Further, since the joint cover 3 can be retrofitted to the joint between the edge of the handrail main body 1 and the joint member 2 as described above, it can be applied to the conventional handrail connection structure. At the time of attachment, the engagement portion 9 of the joint cover 3 is engaged with the protrusion portion 4 of the handrail main body 1 so that the attachment can be performed easily and reliably. The joint cover 3 and the flange 6 are paired.
