Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a connecting member used for connecting a handrail.

[0002]

2. Description of the Related Art Conventionally, several forms have been proposed as connecting members for handrails.

For example, Japanese Patent No. 2659682 discloses that, by rotating an annular operation member provided on one handrail, a screw portion of a disk-shaped member fixed to the other handrail is pulled in, and two opposed handrails are provided. A method is disclosed in which the handrail is fixed with screws.

In Japanese Utility Model Laid-Open Publication No. Hei 6-71694,
A member having a protrusion provided on one handrail is fitted to a member having a hole provided on the other handrail, and one screw passing through a side wall of the hole is used to form a side surface of the protrusion. The method of pressing and fixing is disclosed.

Japanese Patent No. 2577198 discloses that an engagement projection of a member attached to one of the handrails is fitted into an accommodation hole of a member attached to the other handrail from an outer surface so as to cross the accommodation hole. A fastening screw is screwed into the provided screw insertion hole. At this time, a method is disclosed in which a cone at the tip of the tightening screw is brought into contact with a wedge surface of an inner wall of the through hole provided in the fitting protrusion to exert a force for pressing the tightening screw toward one member. Have been.

[0006]

However, in the method disclosed in Japanese Patent No. 2659682, the screw for connecting the handrail is rotatable from the outside.
There is a problem that the connecting portion of the handrail is loosened by erroneously rotating the screw portion after the connecting, and the rattling is likely to occur.

On the other hand, in the method disclosed in Japanese Utility Model Laid-Open Publication No. Hei 6-71694, the tip of one screw is pressed against the side face of the fitted projection and fixed. For this reason, the fixing portion is located slightly closer to the outer periphery than the center of the connection, and buckling may occur with respect to a bending force applied from a direction other than a specific direction. That is, the fixing screw as described above is often attached to the lower side of the handrail so as to be invisible, and has a strength against a force applied from above the handrail. However, since forces are applied to the handrail not only from above but also from various directions, there is a concern that the connecting portion may buckle during repeated use.

In the method disclosed in Japanese Patent No. 2577198, a tightening screw is inserted across the engaging projection and the housing hole to be fitted, and the tightening screw is screwed into the screw insertion hole. However, a sufficient fixing force cannot be obtained between the tightening screw and the through hole only by abutting against the through hole to be subsequently inserted so as to press the inner wall when penetrating the through hole. For this reason, when a force is repeatedly applied to the connecting portion due to the use of the handrail, there is a concern that the screw may gradually loosen and the connection may be weakened.

Further, in any of the above methods, the connecting member is directly exposed in appearance. Therefore, for example, when an appearance matching each handrail is required so as to have a sense of unity with the handrail, or when a design-like appearance is desired according to a user's preference, a connecting member adapted to each handrail is required. Has to be prepared, and there is a problem that the types of the connecting members are diversified too much and are not worth the cost.

[0010] The present invention has been made in view of such problems, and after the handrails are connected, the handrails are firmly fixed without being easily detached or loosened. An object of the present invention is to provide a handrail connecting member that can provide an appearance corresponding to a handrail.

In this component configuration, for example, the length of the male fitting portion 121 is formed to be slightly shorter than the depth of the fitting hole 113 of the concave member 110, and the concave member 110 and the convex member 1 are formed.
This can be achieved by displacing the positions of the holes as described above when 20 is fitted. Further, by slightly increasing the thickness of the cap member 150 or slightly increasing the length of the cover member 140, the distal end side of the female-type fitting portion 111 abuts on the cap member 150 before the fitting is matched. Is also possible. In the above case, the dimensional change in which L becomes zero can be caused by shaving and deforming the wall surface of the locking hole 126 or by changing the cap member 15
0 is elastically deformed and absorbed. With this structure, a strong connection that does not loosen or return even when the handrail is repeatedly used can be obtained.

[0073]

As described above, the handrail connecting member according to the present invention has the concave member and the convex member respectively attached to the ends of the opposing handrails, and these members are fitted and formed. A screw member is inserted into a hole provided in each member so as to cross the connected portion, and at that time, the screw member is screwed into the hole provided in the convex member while cutting a tap. As a result, the rigidity is extremely strong against the entire bending force applied from the outside of the handrail, and the screw member is not loosened even when the handrail is repeatedly used, and an effect of firmly connecting the handrail is brought about.

Further, by covering the connecting portion with a replaceable cover member, it is possible to produce a sense of unity with the same appearance as the handrail, or to select a cover member according to the user's preference. It has excellent convenience in design.
