JPH07303587A - Brushed roller for floor cleaning - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to remove the laterally moving property of the cleaning brush roller that tries to move laterally when rolling on the floor. [Structure] A nap cloth is alternately wound around the shaft side surface of the roller in the forward direction and the reverse direction (representing the reverse direction with respect to the weaving direction), and the area of the part of the nap cloth in which the roller comes into contact with the floor is wound in the forward direction. The areas of the parts wound in the opposite directions are substantially equal to each other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raised cloth roller used for floor cleaning.

[0002]

2. Description of the Related Art A napped cloth always has a directional property when the manufacturing process is completed, and when a roller wound around a cylindrical shaft is rotated on the floor, the napped cloth has a directional property. , A force to move in the axial direction is generated.

In order to solve this problem, conventional measures have been taken such as completely raising the raised hair in one direction.

[0004]

[Problems to be Solved] The conventional countermeasures have the drawback of weakening the original characteristics of raised hair.

The present invention maintains the original characteristics of nap,
An object of the present invention is to obtain a brushed floor cleaning roller that does not generate a force to move in the axial direction of the roller.

[0006]

In order to achieve the above object, according to the present invention, a napped cloth is alternately wound around the roller shaft side surface in the forward direction and the reverse direction (in the weaving direction;
The forward part that contacts the floor and the reverse part should have approximately the same area.

[0007]

[Function] When a roller wrapped with a napped cloth is rotated on the floor, a force to move laterally is generated due to the directionality of the napped cloth, but by wrapping it alternately in the forward and reverse directions, By reversing the directions of the forces and making their areas approximately equal, the lateral forces are totally eliminated.

[0008]

First Embodiment FIGS. 1 and 2 show a first embodiment. As shown in FIG. 1, a raising cloth of the same shape cut out from the base cloth 1 in a zigzag shape is wound around the side surface of the roller alternately in the forward and reverse directions, as shown in FIG. In the figure, two sheets are provided, but one sheet or three sheets may be provided.

[0009]

Second Embodiment A second embodiment is shown in FIGS. Figure-3
As shown in Fig. 4, wrap the slender cut fluff cloth in the forward direction on one side and the reverse direction on the other side as shown in Fig. 4 and wrap it diagonally to the axis as shown in Fig. 5. Thus, the entire roller is wound with one set of raised cloth for each of the forward direction and the reverse direction.

[0010]

[Effect] In both examples, since the areas of the forward direction portion and the reverse direction portion of the portion of the roller around which the napped cloth is wound are in contact with the floor, the direction of the napped cloth depending on the direction of the bristles is directed. However, no axial force is generated.
