Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool such as a mop joint.

[0002]

2. Description of the Related Art In general, a mop has a large number of elongated cloths or thick cords hung vertically from a substrate and a handle protruding from the upper surface of the substrate through a bendable joint. Moreover, the joint is
In many cases, a pair of left and right bearings are erected in parallel from the upper surface of the board, and shafts projecting from the left and right sides of the handle end are fitted into shaft holes formed in the upper parts of the bearings. .

[0003]

SUMMARY OF THE INVENTION In the conventional joint of a handle such as a mop, the protrusion of the handle is directed forward and backward along a vertical plane in the front-back direction with respect to the main body portion formed by the cloth and the substrate. Just change the width of the main body and the vertical width of the main body so that the main body can be used horizontally or vertically depending on the size of the mop. It is necessary to change the protrusion direction of the handle in four directions, front, rear, left and right, so that it can be used properly, and in order to improve the convenience of use, it can be rotated in any direction of 360 °, and It is necessary that the so-called head angle can be adjusted.

Such a joint can be formed by attaching a spherical journal and a spherical bearing to the main body portion and the base end of the handle, but this makes the product expensive because it requires precise processing.

According to the present invention, the spherical member is fitted to the first bearing standing upright from the main body so that the spherical member can be rotated in the left-right direction and can be rotated in the front-rear direction with respect to the spherical member. By fitting the second bearing protruding from the handle to the spherical member in the front-rear direction, the second bearing of the handle in the left-right direction, and the spherical member and the second member in the middle in the front-rear, left-right direction. By providing both of the bearings so as to rotate with respect to the first bearing and the spherical member respectively, it is possible to propose a joint having a relatively simple and functionally superior mop cleaning tool and the like.
