Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor brush machine having a brush brush, a sponge brush, a brush sponged with abrasive particles, a felt brush, a cloth brush or another brush (pad) fixed to a brush base. The present invention relates to floor cleaners such as floor cleaners and polishers, and more particularly to floor cleaners designed to be suitable for cleaning low, narrow, deep places such as under a desk or under a chair.

[0002]

2. Description of the Related Art Conventionally, Japanese Unexamined Utility Model Publication No. 5-39456 discloses a floor polisher in which a portion other than a motor built-in portion is made low. This is as shown in FIG. 7 of the accompanying drawings of the present application.

[0003]

In the floor polisher described in the above-mentioned prior art, the front portion 20 is formed low as can be seen from FIG. 7, but since the front portion is short, When used for cleaning a low, narrow and deep place such as under a desk or under a chair, the motor built-in part (high part) 19 is easily struck and cannot be inserted into the same place. Was happening to. Then, it is necessary to clean the place by another means, for example, by manual work with the person sitting down.

It is an object of the present invention to provide a novel floor cleaner designed so as to be suitable for cleaning a low, narrow and deep place such as under a desk or under a chair.

[0005]

In order to achieve the above object, a floor cleaner according to the present invention comprises a mounting base having a hand handle at the rear and having a narrow left and right width in the front-rear direction, and an upper surface of the rear of the mounting base. The motor mounted on the mounting base, a plurality of rotating brushes arranged in a row on the lower surface of the mounting base on a line in the front-back direction, and rotating by receiving the driving force of the motor via a transmission device such as a belt, and the mounting base. Is provided with a cover having a high rear part provided on the upper surface of the above and other parts having a low shape.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first embodiment shown in FIGS. 1 and 2, a hand handle 1 whose inclination angle can be arbitrarily changed is placed on the upper surface of a rear end portion only when the whole is moved to another place. A mounting base 3 having a narrow left-right width that is long in the front-rear direction and is provided with a portable caster 2 to be used at the rear of the rear end thereof, and a battery 4, on the upper surface of the rear part of the mounting base 3 on the front-rear center line, A five-drive motor 6 is attached with its rotation shaft 7 extending through the lower surface of the mounting base 3, and a first rotating brush 9 is attached to the extension end of the rotation shaft 7 by a bayonet 8 so that it can be attached and detached. The driven shaft 10 is provided in a vertically protruding state at the front of the line, and the driven shaft 10
The second rotating brush 12 is detachably attached to the lower protruding end of the shaft by the bayonet 11, and the pulleys 13 and 14 are fixed to the upper protruding end of the driven shaft 10 and the upper portion of the mount 3 on the rotating shaft 7. A belt 15 is wound around the pulleys 13 and 14, and a cover 18 having a long shape is provided on the upper surface of the mounting base 3 so that the rear portion (motor and battery built-in portion) 16 is high and the other portion, that is, the front portion 17 is low. Further, plate-like weights 21 and 22 are attached to the front end edge of the upper surface of the mounting base 3 and the upper surface of the second rotating brush 12.

The second embodiment shown in FIGS. 3 and 4 is different from the first embodiment in that it is used for alternating current without a battery and in that a dust collecting device 25 by a vaccum motor 24 is provided. is there.

The third embodiment shown in FIGS. 5 and 6 is a third embodiment.
The rotary brush 26 is provided so as to rotate together with the first and second rotary brushes 9 and 12 via pulleys 27 and 28, a rotary shaft 29, a bayonet 30 and a belt 31. In the second and third embodiments, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

According to the present invention, one or both of the weights 21 and 22 are not attached, the battery is used as a weight, and the rotation direction of the second rotary brush is opposite to that of the first and third rotary brushes. It may be carried out.

[0010]

As described above, the floor cleaner according to the present invention includes a mounting base having a hand handle on the rear portion and having a long width in the front-rear direction and a narrow width, a motor mounted on the upper surface of the rear portion of the mounting base, and the mounting base. A plurality of rotating brushes, which are arranged in line on the front-rear direction line on the lower surface of the motor and which rotate by receiving the driving force of the motor through a transmission device such as a belt, and a rear portion provided on the upper surface of the mounting base are high. Other parts are characterized by having a low shape cover, so when using this for cleaning a low, narrow and deep place such as under a desk or a chair, the same place It can be easily inserted and the impact is significantly reduced.

[0011]

When the floor cleaner according to the present invention is used, it is possible to easily clean a low, narrow and deep place, and it is possible to remarkably reduce the manual work of sitting down. Effect is enormous.
