BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint between a main body and a handle such as a rod in a cleaning tool such as a broom, a brush or a mop.

[0002]

2. Description of the Related Art As for a handle joint of a cleaning tool, a joint disclosed in, for example, Japanese Utility Model Publication No. 3-21724 is known which is capable of almost arbitrarily adjusting the angle of the handle with respect to the cleaning tool body. ing. The joint is provided with a hinge portion on each of the cleaning tool main body and the handle side, and a convex portion is provided on one of the opposing surfaces of the pair of hinge portions, and a concave portion is provided on the other, which engages with the convex portion, and These hinges were connected to each other by bolts. Then, when the bolt is tightened, the convex portion and the concave portion engage with each other, so that each hinge portion cannot rotate, and the handle is fixed to the cleaning tool body. When the bolts are loosened to separate the pair of hinge portions from each other, the engagement between the convex portion and the concave portion is released, and each hinge portion can rotate with each other. In this state, the angle of the handle with respect to the cleaning tool body is adjusted. It is. After the angle of the handle is set, the bolt is tightened to fix the handle.

[0003]

The conventional handle joint is suitable for use of a cleaning tool because the angle of the handle with respect to the cleaning tool body can be set almost arbitrarily in accordance with a use condition or the like. However, it is necessary to loosen the bolt each time the angle of the handle is adjusted, move the pair of hinges in the direction of separation, and adjust the angle of the handle before tightening the bolt. Therefore, there is a problem that much effort is required for adjusting the angle of the handle. Further, when the bolts are loosened to separate the pair of hinge portions from each other, the hinge portions can be freely rotated, so that there is no reference for adjusting the angle of the handle, so that it is difficult to set the angle. There is.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides a handle joint of a cleaning tool that requires less labor for adjusting the angle of the handle and that can easily set the angle of the handle with respect to the cleaning tool body. The purpose is to:

[0005]

According to the handle joint of the cleaning tool of the present invention, the handle-side connecting plate is overlapped on the side surface of the main-body-side connecting plate protruding from the cleaning tool main body. The connecting plate and the connecting plate are connected rotatably with each other with a support shaft, and the connecting plate capable of elastic deformation in the thickness direction is
Any one of the side surface of the connecting plate and the side surface of the handle-side connecting plate or the main-body-side connecting plate that is fixed to the end portion of the support shaft, overlaps the side surface of the handle-side connecting plate or the main body-side connecting plate, and overlaps the connecting plate. A convex portion on one side and a concave portion meshing with the convex portion on the other are provided around the support shaft, respectively, and the convex portion and the concave portion mesh with each other,
The support shaft is non-rotatably fixed to the body-side connection plate or the handle-side connection plate where the connection plates do not overlap.

[0006]

In the handle joint of the cleaning tool of the present invention, the main body side connection plate and the handle side connection plate are connected by a support shaft, and the cleaning tool main body and the handle are connected. Adjustment of the angle of the handle with respect to the cleaning tool main body causes the handle to rotate slightly strongly in the circumferential direction of the support shaft. For example, if the connection plate overlaps the side surface of the handle side connection plate, the support shaft is fixed to the main body side connection plate so as not to rotate, and provided on the connection plate and the side surface of the handle side connection plate. The projection and the recess are engaged with each other, and the connecting plate is elastically deformable in the thickness direction. Therefore, when the handle is rotated slightly strongly as described above, the handle-side connecting plate elastically deforms the connecting plate in a direction away from the handle-side connecting plate by a force acting on the handle-side connecting plate. Since the engagement of the concave portion is released, and the next convex portion and the concave portion are repeatedly engaged with each other by the repulsive elastic force of the connecting plate, the handle is appropriately rotated with respect to the cleaning tool main body. The rotation of the handle is stopped in a state where the portion and the recess are engaged. As described above, since the angle of the handle is adjusted only by slightly turning the handle, the labor required for adjusting the angle of the handle is almost unnecessary.
