Description of the Related Art Conventionally, a hand-movable electric floor polisher called a floor polisher used for cleaning a floor surface on which vinyl resin tiles and sheets are laid in buildings, factories, etc. While supplying the cleaning liquid to the floor, a disc-shaped brush is pressed against the floor, and the brush is rotated to clean the floor by strongly rubbing the floor. The floor polisher itself is roughly a brush drive mechanism having a brush cover covering a brush rotated by a built-in motor, and manually tilts the brush drive mechanism in any direction of front, rear, left and right. It comprises a rod-shaped operation handle connected to the brush driving mechanism via a free means controlled by operation, and a moving wheel attached to the free means for moving the brush driving mechanism back and forth. And when cleaning the floor surface using this floor polishing machine, it is performed while moving back and forth along the floor surface and left and right, and in this movement operation, the brush itself is rotating while rubbing the floor surface For this reason, the moving direction is changed by tilting the entire brush driving mechanism back and forth and left and right through free means by tilting the operating handle back and forth or twisting left and right.

[0003]

When the direction of movement of the floor polisher itself, which drives the brush in rotation, is changed in this manner, the entire brush driving mechanism provided with the brush is inclined forward, backward, left and right. At the same time, the gap may be partially formed between the lower edge of the brush cover and the floor surface. Then, in the case of a brush that is rotated to rub the floor surface together with the cleaning liquid supplied when cleaning the floor surface, the cleaning liquid flows around from the gap generated between the lower edge of the brush cover and the floor surface due to centrifugal force caused by the rotation. Will be scattered. This scattered cleaning liquid sticks to the floor surface after cleaning, the surrounding wall surface and the like, especially to the baseboard portion at the bottom of the wall surface, and contaminates it, or soils the feet of the cleaning worker, and then Or make the secondary cleaning troublesome.

Accordingly, the present invention has been made in view of the above-mentioned various circumstances, and the brush drive mechanism is tilted to control the movement of the floor polisher as the floor polisher is manually pushed. The gap between the lower edge of the cover and the floor surface is automatically closed to prevent the washing liquid etc. from scattering to the surroundings, contaminating the surroundings, etc., and the vertical movement of the automatically closing scattering preventing cover to be smooth. It is an object of the present invention to provide a floor polisher washing liquid scattering prevention device which does not hinder the tilting operation or the like of the entire brush driving mechanism.

And comprising: By moving the moving wheel 8 up and down, the whole floor polishing machine main body 1 can be moved when the moving wheel 8 is protruded below the brush driving mechanism 2, and is lifted above the bottom edge of the brush driving mechanism 2. Sometimes, the lower surface of the brush 4 of the brush drive mechanism 2 is in contact with the floor surface, so that the floor surface can be cleaned by the cleaning liquid supplied with the rotation of the brush 4.

The brush cover 5 of the brush drive mechanism 2 is provided with a scattering prevention cover 20 which moves up and down to close a gap around the brush 4 exposed between the lower edge of the brush cover 5 and the floor. It is covered by the scattering prevention device 10. That is, the scattering prevention device 10 includes a support cover 11 that covers the upper portion of the brush cover 5 and bends vertically, and a support cover 1 that surrounds the periphery of the brush cover 5.
The anti-scattering cover 20 is suspended from one peripheral edge and has a lower edge in contact with the floor surface.

The support cover 11 is provided substantially at the center of a substantially disk-shaped cover body made of a soft and soft elastic material so as to cover the entire brush cover 5 of the brush drive mechanism 2. The fitting opening 12 to be fitted around is formed substantially in the shape of a donut disk by forming an opening substantially in the center, and covers almost the entire upper part of the brush cover 5 around the motor 3. The support cover 11 itself is formed of a sheet having a predetermined thickness, for example, a sheet made of a soft synthetic resin material, a sheet made of a rubber material, or the like. Although not shown, the support sheet 11 itself may be formed in a hat shape so as to cover the cover of the motor 3 instead of being formed in a donut shape as shown in the figure.

In the support cover 11, various protrusions provided on the brush cover 5, for example, a U-shaped handle 9 for lifting the floor polishing machine main body 1 itself, and fixed in relation to the brush cover 5 are provided. Heads of bolts for stopping various members to be formed, a power cable for driving the motor 3, a cutout portion 13 for avoiding the above-mentioned flexible means 7 and others.
Is cut out in a donut board part or cut out from the periphery. That is, the support cover 11
When the brush cover 5 is put on the upper surface of the brush cover 5, a cutout portion 13 is formed to avoid an extra protrusion so that the upper surface of the brush cover 5 may be in contact with the upper surface of the brush cover 5. The arrangement of this cutout 13,
The shape, the number, and the like are not limited to the illustrated example, and correspond to the arrangement, the shape, the number, and the like of various protrusions projecting from the upper surface of the brush cover 5.

Further, on the periphery of the support cover 11,
The brush cover 5 is radially arranged by being opened to the outside at the periphery of the support cover 11 so as to be in direct contact with the curved periphery of the brush cover 5 and to bend up and down so as to smoothly move the scattering prevention cover 20 up and down. A plurality of narrowed narrow slits 14 are cut out. Due to the constriction slit 14, the peripheral portion of the support cover 11 comes into contact with the peripheral edge of the three-dimensionally curved brush cover 5 so as to be able to flexibly and flexibly. A constant contact with the floor surface of the lower edge of the scattering prevention cover 20 to be supported is obtained.

On the other hand, the scattering prevention cover 20 is formed of a belt-shaped material of a predetermined width, for example, a soft material such as a rubber plate or a soft synthetic resin plate having an appropriate thickness. Brush cover 5 surrounding the periphery of the cover 5
It surrounds the peripheral portion of the brush 4 inside. The scattering prevention cover 20 itself is supported in a hanging manner from the peripheral portion of the support cover 11 by, for example, welding, pinning, stringing with a string or a wire material, or other appropriate fixing means 19, as shown in FIG. As shown in FIGS. 3 to 3, the peripheral edge of the support cover 11 and the upper edge of the shatterproof cover 20 overlap each other, or as shown in FIGS. The rim and the rim are arranged so as to be substantially orthogonal to each other when viewed from the side, or in some cases they are integrally formed although not shown.

The support cover 1 via the fixing means 19
The scatter prevention cover 20 is connected to the brush cover 5 by the support cover 11 when the brush drive mechanism 2 is tilted in an arbitrary direction.
The height of the shatterproof cover 20 is set so that the lower edge of the shatterproof cover 20 is constantly in contact with the floor surface as the peripheral edge of the shatterproof member 20 is bent. That is, when the scattering prevention cover 20 is attached around the brush cover 5 and the lower edge is in contact with the floor surface, the brush driving mechanism 2 is pushed up from the floor surface in response to the inclination in an arbitrary direction. Or the peripheral edge of the support cover 11 is flexibly bent so that the scattering prevention cover 20 is partially tilted and displaced by being moved down by its own weight or the like.
The support cover 11 itself must be prevented from coming off the brush cover 5 by smooth sliding along the vertical direction of the brush cover 5 itself. The bending flexibility of the peripheral portion of the support cover 11 is set so as to allow such partial inclination and displacement of the scattering prevention cover 20 itself.
The length is set in advance along with the length of the scattering prevention cover 20 substantially corresponding to the diameter and the like.

As shown in FIG. 4 and FIG.
1. The brush cover 5 can be tilted and swung in the air space surrounded by the scattering prevention cover 20.
That is, the height of the scattering prevention cover 20 itself is set to be larger than the interval between the floor surface rubbed by the brush 4 and the maximum height position of the upper surface of the brush cover 5 when the brush 4 tilts and swings.
By providing the scattering prevention cover 20 having a certain degree of rigidity, the scattering prevention cover 2 surrounding the periphery of the brush cover 5 is formed.
The brush cover 5 is freely tilted and swung within the zero air space. By doing so, the brush cover 5 can freely tilt and swing in the air space defined by the scattering prevention cover 20 surrounding the brush cover 5 with a slight gap from the peripheral edge of the brush cover 5, and the scattering prevention cover 20 Does not move up and down to prevent scattering of the cleaning liquid and the like.

The height of the shatterproof cover 20 is considered to be versatile enough to cope with different heights when the brush 4 itself is selected as a hard or soft type. It is desirable to form it.

Next, an example of the use of the brush cover 5 will be described.
On the upper part, the cover of the motor 3 is avoided by the fitting opening 12 and covered by the support cover 11. By covering the brush cover 5 with the support cover 11, the scattering prevention cover 20 whose lower edge is in contact with the floor surface is supported and fixed around the brush cover 5. The shatterproof cover 20 is set on the floor polishing machine main body 1 in the surrounding state. Next, the floor polishing machine main body 1 may be used in accordance with a normal usage. At this time, the lower edge of the shatterproof cover 20 is always in contact with the floor surface. At the time of the conversion, when the brush driving mechanism 2 is tilted by the operation handle 6, even if a gap is generated on the side of the brush driving mechanism 2 between the surface of the brush 4 and the floor surface, the scattering prevention cover 20 is located at the peripheral portion of the support cover 11. The cover 20 is automatically moved up and down or displaced even partially due to deflection, or the scattering prevention cover
When the brush cover 5 tilts and swings in the air space surrounded by the above, the gap that may occur between the lower edge of the brush cover 5 and the floor surface is closed, and the cleaning liquid and the like are not scattered around.

[0017]

According to the present invention, the brush driving mechanism 2 of the floor polishing machine main body 1 is tilted so as to control the movement of the floor polishing machine as the floor polishing machine travels. As a result, the gap formed between the lower edge of the brush cover 5 and the floor surface is automatically closed to prevent the washing liquid and the like from scattering around, contaminating the surroundings, and the like. In addition, the vertical movement of the scattering prevention cover 20 that automatically closes the gap is also smooth,
Further, the tilting and swinging of the brush cover 5 itself in the air space in the scattering prevention cover 20 is made free, and the tilting operation for the entire brush driving mechanism 2 is not hindered.

That is, in the present invention, the brush 4
Cover 5 of the brush drive mechanism 2 covering the brush
The support cover 11 which is covered on the upper part, and the scattering prevention cover 20 which surrounds the periphery of the brush cover 5 and hangs down from the support cover 11 or is connected to the periphery of the support cover 11 and the lower edge of which is in contact with the floor surface. With this, the gap between the brush cover 5 and the floor surface, which may be caused by the inclination of the brush driving mechanism 2, can be partially or displaced up and down by the scattering prevention cover 20 or the scattering. When the brush cover 5 tilts and swings in the air space in the prevention cover 20, the brush cover 5 can be closed, and the scattering of the cleaning liquid or the like to the surroundings can be prevented.

Since the support cover 11 has an opening formed with a fitting opening 12 for fitting to a drive source such as the motor 3 of the brush drive mechanism 2 on the brush cover 5, the support cover 11 is arranged on the upper surface of the brush cover 5 in a fitted manner. The brush cover 5 can be easily mounted with one touch. In addition, the support cover 11 is formed of a soft elastic material, and the support cover 11 itself is flexibly bent along the upper surface of the brush cover 5, and the periphery thereof smoothly bends along the vertical direction. The up-and-down movement of the scattering prevention cover 20 caused by the tilting swing of the brush drive mechanism 2 is made smooth, and the scattering prevention cover 2
The lower edge of the cover 0 is always stably brought into contact with the floor, and no gap is formed between the lower edge of the shatterproof cover 20 and the floor.

A support cover 11 which covers the upper part of the brush cover 5 and an anti-scattering cover 20 which surrounds the periphery of the brush cover 5 and is connected to the periphery of the support cover 11 and has a lower edge in contact with the floor surface. The brush cover 5 is tilted and rocked in the open air space. Therefore, even if the brush cover 5 itself tilts and rocks freely as the floor polishing machine body 1 moves in various directions, the brush Scattering of the cleaning liquid and the like from the brush 4 rotating in the cover 5 to the surroundings can be reliably prevented.

Further, since the scattering prevention cover 20 is made detachable from the brush cover 5 by the support cover 11, the cleaning liquid is worn or scattered and adhered, for example, when the lower edge of the scattering prevention cover 20 itself contacts the floor surface. When it is contaminated by, for example, the scattering prevention cover 20 can be freely attached and detached by the support cover 11 when replacing or checking the scattering prevention cover 20, and the like.
In some cases, a cleaning operation without using the scattering prevention cover 20 is also enabled.
