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 protrudes below the brush driving mechanism 2, and is raised 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, and the floor surface can be cleaned by the cleaning liquid supplied with the rotation of the brush 4.

A 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. The scattering prevention device 10 is provided at appropriate intervals along the outer peripheral surface of the brush cover 5, and has a support body 11 having a vertically movable fastening mechanism 15, and a fastening mechanism surrounding the brush cover 5. 15 and a scattering prevention cover 20 whose lower edge is in contact with the floor surface.

The support 11 is fixed so as to surround the outer periphery of the brush cover 5 for a buffering action when the outer peripheral surface of the brush cover 5 collides with, for example, furniture, a wall surface or other various members during cleaning by the brush 4. As shown in the figure, the guard member 12 is formed in a loop structure by a band plate material so as to be attached to the guard member 12 in the vertical direction, for example, from above. That is, a slide restricting portion 11B disposed on the surface of the guard member 12 is continuously provided from an upper end of the base portion 11A disposed on the back surface of the guard member 12, and the slide restrictive portion 1B is provided.
1B is provided with a fastening mechanism 15 that slides up and down. A mounting portion 11C bent from the lower end of the slide restricting portion 11B is engaged with a fixed portion 11D connected to the lower end of the base portion 11A. Therefore, the mounting portion 11C is substantially L-shaped when viewed from a plane. The mounting portion 11C is inserted into and engaged with a horizontally elongated slit formed in the fixing portion 11D. In order to attach such a support 11 to the guard member 12, the base member 11A is arranged on the back surface of the guard member 12 and the slide regulating portion 11B is arranged on the front surface, respectively.
(2) After mounting from above, the mounting portion 11C is engaged with the fixing portion 11D, so that the support 11 can be mounted on the guard member 12 while the guard member 12 is vertically surrounded. To be able to
The support position can be moved and adjusted along the guard member 12.

Note that the guard member 12 is formed of a soft elastic band-shaped material such as rubber or soft synthetic resin material having a suitable thickness and a predetermined width so as to be mounted on the outer periphery of the brush cover 5, and in some cases, a metal band or the like. As shown in the figure, the lower end of the brush cover 5 is supported so as not to be detached below the brush cover 5 by being engaged with a protruding edge portion 5A formed to protrude outward at the lower edge. . The support 11 itself is arranged and fixed by forcibly inserting the base portion 11A into the gap between the guard member 12 and the brush cover 5, and the step portion 1 formed at the end of the base portion 11A is fixed.
By positioning 1F in the gap between the lower edge of the guard member 12 and the protruding edge 5A, the support 11 itself is prevented from falling off or falling down, and the mounting portion 11 engaged with the fixing portion 11D.
By taking the C-end into contact with the lower surface of the protruding edge 5A, care is taken to prevent the support body 11 and the guard member 12 and the like from being pulled out or separated upward (see FIG. 3). By doing so, the integration of the guard member 12, the support 11 and the like into the brush cover 5 can be further ensured, and the scattering prevention cover 20 which moves up and down when coming into contact with the floor surface allows the support 11 and further the guard member 12 and the like. Of the brush cover 5 and the support 11 of the scattering prevention cover 20 itself.
This makes partial and displacement vertical movements smoother.

Further, as shown in the figure, the fastening mechanism 15 is vertically moved along a slide guide hole 16 which is long perforated in a vertical direction in a slide restricting portion 11B reinforced by reinforcing edges 11E formed by bending both side edges. A detachable means such as a magnetically attached type, a hook type, a hook-and-loop fastener type is attached to a slide body 17 which is slid and moved. Slide body 17
Are fixedly connected large and small disc members arranged on the front and back of the slide guide hole 16 with appropriate pin members, and are formed of a magnetic material that can be magnetically attached, for example, an iron material.

On the other hand, the scattering prevention cover 20 is formed of a band member made of a soft material such as a rubber plate or a soft synthetic resin plate having a predetermined width, for example, having an appropriate thickness. It is detachably attached to the support 11. In the figure, magnet members 15A are arranged and fixed at appropriate intervals on the back surface of the scattering prevention cover 20 itself, and this magnet member 15A is attached to a fastening mechanism 1 made of a magnetic material.

Naturally, in the fastening mechanism 15 of the magnetic attachment type, the magnet material 15A of the permanent magnet is
Instead of being attached to the side, it is also possible to attach it to the support 11 side, and in some cases, it is also possible to arrange both the support 11 side and the scattering prevention cover 20 side so that the polarities correspond to each other. is there. The detachable means is not limited to the magnetically attached type as described above, but may be a hook type, a hook-and-loop fastener type, or a fitting type of male and female members, a hook engaging type, a binding type using a string material or the like, and the like. There is no particular limitation.

The attachment / detachment means such as the fastening mechanism 15 and the magnet material 15A are attached to the brush drive mechanism 2 with the scattering prevention cover 20 attached via the slide body 17 attached to the support 11. As the slide body 17 slides upward or downward when tilted in an arbitrary direction, the lower edge of the shatterproof cover 20 is always in contact with the floor surface, so that the lower edge of the shatterproof cover 20 is always in contact with the floor surface. Is set. The fastening mechanism 15 corresponds to the case where the brush drive mechanism 2 is tilted in an arbitrary direction when the lower edge is in contact with the floor surface in a state where the scattering prevention cover 20 is mounted around the brush cover 5. So that the scattering prevention cover 20 is partially tilted and displaced following the floor by being pushed up from the floor surface or falling by its own weight.
It is necessary to smoothly slide the slide body 17 along the slide guide hole 16 and to prevent the scattering prevention cover 20 from coming off the support body 11 by the slide. The arrangement interval, the number, and the like of the fastening mechanisms 15 are selected so as to allow the partial inclination and displacement of the scattering prevention cover 20 itself, and these are substantially the same as, for example, the size and diameter of the brush driving mechanism 2. Correspondingly, the length is set in advance together with the length of the scattering prevention cover 20 itself.

Next, an example of the use of the brush cover 5 will be described.
The support member 11 is attached to the guard member 12 mounted around the periphery, and the scattering prevention cover 20 whose lower edge is in contact with the floor is supported and fixed to the slide member 17 of the support member 11 by the fastening mechanism 15. 5, by surrounding the periphery of the brush 4 exposed below,
0 is set in the floor polishing machine main body 1. 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 this time, when the brush drive mechanism 2 is tilted by the operation handle 6, the brush drive mechanism 2 is moved between the brush 4 surface and the floor surface.
Even if a gap is formed on the side, the scattering prevention cover 20 is automatically moved up and down and displaced even partially, thereby closing the gap and preventing the washing liquid or the like from scattering around.

[0016]

Since the present invention is constructed as described above, the brush driving mechanism 2 of the floor polishing machine main body 1 is tilted in order to control the movement of the floor polishing machine as the floor polishing machine travels. The gap created 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 to the surroundings, soiling the surroundings, and the like, and to prevent the gap from being automatically closed. The vertical movement of the cover 20 is also smooth, so that the tilting operation and the like for the entire brush driving mechanism 2 are not hindered.

That is, in the present invention, the brush 4
Cover 5 in the brush drive mechanism 2 that covers the brush
A support body 11 having a fastening mechanism 15 arranged and arranged on the outer peripheral surface and capable of moving up and down, and is detachably fastened to the fastening mechanism 15 so as to surround the periphery of the brush cover 5 so that the lower edge is in contact with the floor surface. This is because it is provided with a scattering prevention cover 20, whereby the gap between the brush cover 5 and the floor surface, which may be caused by the inclination of the brush driving mechanism 2, is vertically moved even partially or displaceably. This can be closed by the cover 20, and scattering of the cleaning liquid and the like to the surroundings can be prevented.

The support 11 includes a base portion 11A and a slide restricting portion 11B disposed on the front and back surfaces of a guard member 12 disposed around the brush cover 5, a mounting portion 11C for engaging both of them, and a fixing portion. By providing the portion 11D, a position along the guard member 12 can be selected and attached to the guard member 12, and the fastening mechanism 1 provided on the support 11
5 can correspond to the fastening mechanism (15) of the scattering prevention cover 20, for example, the position of the magnet material 15A. When attaching the support 11 to the guard member 12, an attachment portion 11 </ b> C having a substantially L-shaped outline when viewed from a plane.
Is inserted into and engaged with a horizontally elongated slit formed in the fixing portion 11D, so that the mounting portion 11C is inserted into the guard member 12 from above, for example, and then the fixing portion 11C is fixed.
It can be easily engaged and fixed simply by pushing it in close to the 1D even if it is forced.

The fastening mechanism 15 provided on the support 11 is vertically movable along a slide guide hole 16 formed in a slide regulating portion 11B located on the surface side of the guard member 12. When the lower edge of the scattering prevention cover 20 supported by the attachment mechanism 15 is in contact with the floor surface, the brush drive mechanism 2 is lowered when the space between the floor surface and the floor surface is largely opened due to the inclination of the brush drive mechanism 2, and conversely the space between the floor surface and the floor surface is narrowed. Sometimes, it is lifted up, and the gap created between the brush 4 or the brush cover 5 and the floor is reliably and automatically closed.

Further, the support 1 is provided by the fastening mechanism 15.
The scatter prevention cover 20 is made detachable with respect to the base member 1. For example, when the lower edge of the scatter prevention cover 20 is worn due to contact with the floor surface, or when the scatter prevention cover 20 is contaminated by a washing liquid or the like adhered to the floor, the scatter prevention cover 20 is scattered. The scatter prevention cover 20 can be freely attached to and detached from the support 11 when the proof cover 20 is replaced or inspected, and in some cases, a cleaning operation without using the scatter prevention cover 20 is also enabled.
