[0001]

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

[0002]

2. Description of the Related Art In general, a mop has a large number of slender cloths or thick strings suspended from a substrate, and a handle protrudes from a top surface of the substrate via a bendable joint. And the joint is
In many cases, a pair of left and right bearings are erected in parallel at an interval from the upper surface of the substrate, and shafts protruding from the left and right sides of the handle tip are fitted into shaft holes formed in the upper portion of the bearings. .

[0003]

In the conventional joint of a mop or the like, the joint of the handle or the like is formed so that the direction in which the handle protrudes forward and rearward along the vertical plane in the front and rear direction with respect to the main body formed by the cloth and the like. Just change the length of the body part and the width of the body part, and use the body part sideways or vertically according to the size of the mop use place etc. In order to be able to use properly, it is necessary to change the protruding direction of the handle to four directions of front, rear, left and right, and in order to further improve usability, it can rotate in any direction of 360 °, It is necessary to form the head so that the head angle can be adjusted.

[0004] 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. However, such a process requires precise processing, and the product becomes expensive.

According to the present invention, a spherical member is fitted so as to be rotatable in the left-right direction with respect to a first bearing raised from the main body, and is rotatable in the front-rear direction with respect to the spherical member. By fitting a second bearing projecting from the handle to the second member, a spherical member is provided in the front-rear direction, the second bearing of the handle is provided in the left-right direction, and the spherical member is connected to the second member in the middle direction of the front, rear, left and right. By providing both bearings so as to rotate relative to the first bearing and the spherical member, a joint having a relatively simple and functionally superior handle such as a mop cleaning tool is proposed.
