Abstract

<P>PROBLEM TO BE SOLVED: To enhance a function of polishing the surface of an object by making a rotary brush for cleaning self-rotate by a work action. <P>SOLUTION: The brushing work is performed by pressing the brush against an object and moving the brush back and forth or to the right and left. The brush is used as a rotary brush by making it self-rotate using frictional resistance between the object and the brush. When the frictional resistances of the right and left of the brush shaft are not equal between the object and the brush in the brushing work direction, rotation torque corresponding to the difference of the frictional resistances is generated, to make the rotary brush self-rotate. As one way of making the contact resistance different at the right and left of the shaft of the rotary brush, the shaft of the rotary brush is slightly tilted toward the right or the left with respect to the movement of the brush. As another way of making the contact resistance different at the right and left of the shaft of the rotary brush, the brush is pressed against the object with force different at the right and left of the shaft of the rotary brush with respect to the movement of the brush. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a cleaning rotary brush that rotates by a brushing operation.

  Conventionally, many brushes have been used as cleaning tools, and rotating brushes that are rotated by external power are also frequently used in order to further improve the cleaning ability.

External power includes a motor and a rotating brush that is rotated by a water flow. However, the structure is complicated, and it is not easy to use and may cause a failure.

  A rotating brush that is rotated by external power as a cleaning tool has a complicated structure, is heavy, and is not easy to use, and improves the convenience as a self-rotating rotating brush that does not rely on external power.

The structure is simplified, the cause of failure is reduced, the direction of brushing is reduced, the weight is reduced, and the usability is improved.

By changing the material and hardness of the self-rotating brush, it can be used for various purposes such as car wash brushes and waxing.

  In the brushing operation, the brush is pressed against the object and rubbed back and forth or left and right. However, the rotating brushes 1 and 11 are used by using the frictional resistance between the rotating brushes 1 and 11 and the object by the operation. Try to rotate.

If the left and right frictional resistances of the brush shafts 2 and 12 of the rotating brushes 1 and 11 are different from the object with respect to the direction of the brushing operation of the brushing operation, the rotational torque corresponding to the difference between the left and right frictional resistances Occurs, and the rotating brushes 1 and 11 rotate by themselves.

In order to generate different frictional resistances on the left and right of the brush shafts 2 and 12 of the rotating brushes 1 and 11 with respect to the direction of the brushing operation of the brushing operation, different pressing forces are used on the left and right of the brush shafts 2 and 12. What is necessary is just to press on an object.

As one method for generating different frictional forces on the left and right of the brush shaft 2 of the rotating brush 1 with respect to the brushing direction, the brush shaft 2 of the rotating brush 1 is slightly tilted left or right to the object. Press.

The larger the inclination angle 4 of the brush shaft 2 of the rotating brush 1 is, the larger the difference between the left and right frictional resistances is, and a strong rotational force is generated. However, if the required rotational force is obtained, the smaller the inclination angle 4 can be evenly polished. preferable.

As a second method of generating different frictional resistances on the left and right of the rotating brush shaft 12 with respect to the brushing direction, the rotating brush 11 is pressed against the object with different pressing forces on the left and right of the brush shaft 12. .

Rotational brushes 1 and 11 generate self-rotating force and self-rotate by generating a rotational torque corresponding to the difference in frictional resistance between the left and right brush shafts 2 and 12 of the rotating brushes 1 and 11.

  Since the cleaning rotary brushes 1 and 11 themselves generate a rotational force without adding a self-rotating means to the outside, the structure can be simplified and maintenance can be facilitated.

Since the rotating brushes 1 and 11 rotate by themselves, the direction of brushing can be reduced, and tile joints and the like can be polished uniformly.

  Since the cleaning rotary brushes 1 and 11 themselves generate a self-rotating force, the structure can be simplified, the direction of brushing can be reduced, and the object can be rubbed uniformly.

The self-rotating brush for cleaning of the present invention will be described in detail with reference to the drawings.
In FIG. 1, in order to make the frictional resistance of the left and right of the brush shaft 2 unbalanced with respect to the brushing direction, the brush shaft is slightly tilted right or left and pressed against the object.

In FIG. 1, two rotating brushes 1 are used, and the brush shaft 2 of the right rotating brush 1 is tilted to the left and the brush shaft 2 of the left rotating brush 1 is tilted to the right. The frictional resistance inside the brush shaft 2 of the rotating brush 1 is increased.

The inner frictional resistance is increased by the operation of the brushing operation, and rotational torque corresponding to the difference from the outer side is generated, and the rotating brush 1 rotates in the direction shown in FIG.

The direction of inclination of the brush shaft 2 of the rotating brush 1 can be either left or right with respect to the direction of the work operation, but the direction of self rotation changes depending on the direction of inclination.

The larger the tilt angle of the self-rotating brush shaft is, the stronger the self-rotating force is generated. However, if the required rotating force is obtained, the smaller the tilt angle, the more preferable the uniform brushing.

Although the inclination angle 4 of the brush shaft 2 of the rotating brush 1 varies depending on the material of the rotating brush, the hardness of the fiber, and the object, it is about several degrees and is as small as possible within a range where a necessary rotational force can be obtained.

  In FIG. 2, in order to unbalance the left and right frictional resistance of the brush shaft 12 with respect to the object relative to the brushing direction, the left and right pressing force of the brush shaft 12 is imbalanced and pressed against the object. It is what I did.

The brush shaft 12 is pressed by two sets of springs having different spring coefficients, that is, a pressing spring 14 and an auxiliary pressing spring 15 on the left and right of the brush shaft 12 with respect to the brushing operation direction. 14 has a stronger spring coefficient.

In FIG. 2, the frictional resistance increases between the rotating brush shaft 12 and the object, and the rotating brush 11 rotates in the direction shown in FIG.

The strength of the different springs and the like are selected in a range where a necessary rotational force can be obtained in consideration of the material of the rotating brush 11, the hardness of the fiber, the object, and the like.

  The external shape of the self-rotating brush may be provided with a long handle such as a deck brush according to the purpose of the work, and a plurality of rotating brushes 1 and 11 may be provided side by side.

The rotation direction of the rotary brushes 1 and 11 only needs to be rotated, and may be rotated in a direction different from the embodiment.

The bearing should have a low resistance, and a ball bearing or the like may be used. However, it is necessary that a bearing that handles water does not generate rust.

  If the rotating brushes 1 and 11 are made of steel rotating brushes 1 and 11, they can be used for removing rust on an iron plate, and if they are sponge brushes, they can also be used for waxing automobiles.
