Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handrail connection structure, and more particularly to a handrail connection structure suitable for connecting handrails in a non-linear manner.
[0002]
[Prior art]
Conventionally, as a connection structure of handrails provided indoors and outdoors such as stairs, corridors or bathrooms, Japanese Utility Model Publication No. 64-27332 discloses a connecting part consisting of a lower half at the front part of a horizontal cylindrical joint structure. And forming the outer shape of the front half of the connecting portion into a sphere of a quarter of a sphere, and the upper half of the latter half of the connecting portion has a spherical surface on the inner surface of which the spherical surface is fitted. Are formed so as to project forward, and a pair of such joint components is used, and the tip spherical surface of the connecting portion of one joint component is fitted to the inner spherical surface of the projecting piece of the other joint component. There is proposed a handrail corner joint in which both the joint components are rotatably connected by inserting a bolt through the center of the connecting portion.
[0003]
[Problems to be solved by the invention]
However, in the handrail connection structure using the handrail corner joint as described above, the connection parts of the pair of joint components are connected to each other so that they are connected when a torsional moment is applied to the connection part. There was a problem that the part was easy to shift.
[0004]
Therefore, the present inventor intends to provide a handrail connection structure that is excellent in structural strength and capable of joining handrails at an arbitrary angle as a result of intensive studies in view of the conventional drawbacks.
[0005]
[Means for Solving the Problems]
The connecting structure of the handrail of the present invention is a handrail in which a convex connector provided at one end of one handrail body and a concave connector provided at one end of the other handrail are pivotally mounted. In the connection structure, the convex connector has a base portion attached to the handrail body and a convex portion projecting from the base portion, and the convex portion has a disk-like shape in which the top and bottom of the sphere are omitted. The concave connector is composed of a base portion attached to the handrail body and a concave portion projecting from the base portion, and the concave portion has a shape in which the center of the sphere is removed in a disk shape. The convex portion is inserted into the concave portion of the concave coupling tool and is pivotally coupled by a coupling shaft passing through the convex portion and the concave portion, and a spherical body is formed by the coupled convex portion and the concave portion. Since the convex part is clamped and connected to the concave part of the concave connector, it has excellent structural strength and a twisting moment at the connecting part. Hard connecting portion is displaced even when bought.

At the other end of the base portion 21, the center of the sphere is cut into a disk shape to form a recess 23. A through hole is formed in the center of the upper hemispherical body constituting the recess 23, and a countersink 24 is formed at the opening edge of the through hole. A sealing hole 25 having a lower end sealed is formed at the center of the lower hemispherical body. A spherical recess 26 is formed at the center of the recess 23, and one side of the spherical recess 26 is cut away.
[0009]
In the connection of the handrail, the convex portion 13 of the convex connector 1 provided at the end of the other handrail is inserted into the concave portion 23 of the concave connector 2 provided at the end of one handrail. Then, a countersunk screw is inserted from the upper end of the concave part 23, screwed into the lower part of the concave part 23, and the convex part 13 and the concave part 23, which overlap each other, are pivotally mounted with the countersunk screw as a connecting shaft. The convex portion 13 and the concave portion 23 that overlap each other form a sphere, and the shape of the coupling portion does not change even when the coupling tools are coupled at an arbitrary angle. When the handrail is used, even when the hand is slid on the handrail, the connecting portion has no sharp protrusion, and is safe and comfortable to touch.

【The invention's effect】
As described above, the connection structure of the handrail of the present invention is such that the convex connector provided at one end of one handrail body and the concave connector provided at one end of the other handrail are pivotally mounted. In the connection structure of the handrail, the convex connector is composed of a base portion attached to the handrail main body and a convex portion 13 projecting from the base portion, and the convex portion is formed by removing the top and bottom of the sphere. It has a disk-like shape, and the concave connector is composed of a base attached to the handrail main body and a recess protruding from the base, and this recess has a shape in which the center of the sphere is removed in a disk shape, The convex part of the convex connector is inserted into the concave part of the concave connector and is connected rotatably by a connecting shaft that penetrates the convex part and the concave part, and a sphere is formed by the connected convex part and the concave part. Since the convex part of the convex connector is clamped and connected to the concave part of the concave connector, it has excellent structural strength and Ri connecting portion is less likely to shift even when the moment is applied. Moreover, the handrail to be connected can be connected at an arbitrary angle, and the shape of the connecting portion does not change regardless of the connecting angle. In addition, since a spherical body is formed at the connecting portion, when using a handrail, even when the hand is slid on the handrail, the connecting portion has no acute angle convex portion, and is safe and has a good touch.
