Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool used for cleaning a floor or the like by attaching a dirt-wiping sheet.

[0002]

2. Description of the Related Art A tool of this kind is disclosed in Japanese Patent Laid-Open No. 6-7887.
No. 2 discloses a plate-shaped body for attaching and detaching a wiping sheet,
It is disclosed that the long handle is pivotally attached to the upper surface of the plate. The plate-like body has a rectangular shape, and clamping means for seat fastening is formed on both sides of the upper surface, and a large number of elastic protrusions having the same length extend downward in the vertical direction on the lower surface. The central portion of the sheet is in contact with the tips of the elastic protrusions, and the side edge portions are folded on the upper surface of the plate-like body and clamped by the means.

[0003]

There are various kinds of dust on the floor, such as light dust such as cotton, and dust that cannot be captured unless it is adhered to the floor and scraped off. It is preferable that the cleaning tool can capture a large amount of dust without distinguishing between the types.

In the above-mentioned known cleaning tool, when the emphasis is placed on scraping dust, it is necessary to make the protrusions relatively hard and not easily deformed. However, with such a tool, it is difficult for light dust such as cotton to enter under the wiping sheet, and the dust cannot be captured by this sheet. On the other hand, if the protrusions are made flexible, it becomes difficult to scrape the dust, although it is easy to capture light dust.

In view of the above, the present invention has an object to make it possible to simultaneously capture light dust and dust attached to the floor surface in a cleaning tool to which a wiping sheet is attached.

[0006]

In order to solve the above-mentioned problems, the present invention is based on the premise that a long handle is attached to the upper surface of a rectangular plate through a universal joint and the lower surface of the plate is attached. A cleaning tool that has a large number of elastic projections arranged intermittently along the long sides and the short sides of the rectangle and that is used by contacting the tip of the projections with a dirt wiping sheet to be attached to and detached from the plate-like body. The present invention is characterized in that the protrusion is a horizontal pusher acting orthogonally to the center line as it approaches the long side from the center line of the plate-shaped body that bisects the short side. It is formed so as to be easily elastically deformed by pressure.

BEST MODE FOR CARRYING OUT THE INVENTION The details of the cleaning tool according to the present invention will be described below with reference to the accompanying drawings.

A cleaning tool 1 shown in a perspective view in FIG. 1 is composed of a plate-like body 2 and a long handle 4 attached to the plate-like body 2 via a universal joint 3, and has a lower surface of the plate-like body 2. The disposable dirt wiping sheet 5 that covers the sheet and has the edges folded on the upper surface is shown by an imaginary line.

The plate-like body 2 is a rectangle that is long in the left-right direction in the drawing, and has a main body 8 made of hard plastic having a pair of long sides 7A and a pair of short sides 7B, a lower surface of the body 8 and a peripheral portion. And an elastic lower surface member 9 for covering. A pair of left and right protrusions 11 forming a part of the universal joint 3 are formed at the center of the upper surface 10 of the main body 8, and clamp members 13 are pivotally attached to both left and right sides. The clamp member 13 that is closed opens in the direction of the arrow P around the inner end portion 14 that is pivotally attached to the main body 8 when the outer end portion 15 of the clamp member 13 is gripped and lifted. When the parts are placed on the upper surface 10 of the main body and closed again, the sheet 5 is placed on the upper surface 1
Can be clamped to zero.

The long handle 4 is made of hard plastic and is rotatable in both directions of double-headed arrows Q and R.

2 and 3 are a plan view of a main part of the elastic lower surface member 9 as viewed from below and a view taken along the line III-III in FIG. The lower surface member 9 is a rectangle having a long side 9A and a short side 9B that are parallel to the long side 7A and the short side 7B of the main body 8, respectively, and the groove 17 of the peripheral edge fits into the peripheral edge of the main body 8, It is integrated with the body 8. On the lower surface of the lower surface member 9, a large number of projections 21 are intermittently arranged along the long sides 9A and the short sides 9B and extend downward. The projection 21 has its tip 22 on a substantially horizontal plane X, and the
A quadrangle having a length H up to 3, a width W along the long side 9A, and a thickness T along the short side 9B, and a horizontal cross-sectional shape defined by the width W and the thickness T. Or a circle or oval that inscribes or circumscribes the quadrangle. Adjacent protrusions 21 have a separation distance m and n along the long side 9A and the short side 9B. The lower surface member 9 preferably has a long side 9A in a range of 200 to 800 mm and a short side in a range of 50 to 200 mm.
Is located in the vicinity of the center line D-D that bisects, and the thickness T is relatively thick, and the thickness T becomes thinner as it approaches the long side 9A. The thickness T is preferably in the range of 1 to 5 mm and does not exceed the width W. The height H of the protrusion 21 is 0.5 to 5 mm,
The separation distances m and n are preferably in the range of 1 to 7 mm. The lower surface member 9 is a molded product such as a thermoplastic, an elastomer, or a synthetic rubber having required flexibility and elasticity.

In the cleaning tool 1 having such a structure, a non-woven cloth dirt-cleaning sheet 5 impregnated with a required oil agent is shown in FIG.
As shown in Fig. 5, the long side 9A is moved back and forth, and the floor surface is rubbed by alternately moving in the Y and Z directions.
The relatively thin protrusions 21 in the vicinity easily bend, so that light dust quickly enters the lower side of the dirt wiping sheet 5 and is captured there. The dust that adheres to the floor and is relatively hard to remove is scraped off by the protrusion 21 near the center line D-D that is thick and relatively difficult to deform after entering the lower side of the seat 5, and is captured by the seat 5.

FIG. 4 is a sectional view similar to FIG. 3, showing an example of the embodiment of the present invention. The protrusion 21 of the elastic lower surface member 9 of the cleaning tool 1 becomes higher in height H from the horizontal plane X as it approaches the long side 9A from the center line DD. Each protrusion 2
The width W and the thickness T of 1 are substantially the same, and
When the floor is rubbed by alternately moving it in the Z direction, the protrusion 21 closer to the long side 9A is greatly bent, and dust easily enters the lower side of the dirt wiping sheet 5. Protrusion 21 near the center line DD
Since is low in length and does not bend easily, it is possible to rub the floor surface strongly here and scrape off dust adhering to the floor.

In the cleaning tool 1 shown in FIG. 4, the protrusion 21 may have a mode in which the height H increases and the thickness T increases as it approaches the long side 9A.

FIG. 5 is a drawing similar to FIG. 3 showing another example of the embodiment. In this cleaning tool 1, the center line DD
The neighboring projection 21 is relatively projected downward,
The wiping sheet 5 attached to the plate-shaped body 2 (a part of which is shown by an imaginary line) is bilaterally symmetrical with respect to the center line D-D and forms a downwardly convex curved surface W. The protrusion 21 is
The length H from the curved surface W is the same, and the thickness T is the center line DD
Becomes thinner as it approaches the long side 9A. In this cleaning tool 1, the protrusion 21 is easily bent near the long side 9A, and when the protrusion 21 near the center line DD comes into contact with the floor surface F as shown in the drawing, the long side 9A is removed. Neighborhood and floor F
Since and are separated from each other, even a relatively bulky dust enters under the wiping sheet 5 and is relatively easily caught there.

In the cleaning tool 1 shown in FIG. 5, the projection 21 may have a mode in which the thickness T becomes smaller as it gets closer to the long side 9A, and at the same time the height from the curved surface W becomes higher. It may be a mode in which only the value becomes high.

[0017]

In the cleaning tool according to the present invention, among a large number of elastic projections forming the lower surface of the rectangular plate attached to the long handle, the one located near the long side of the plate has a horizontal direction. Since it is easily deformed under the pressing force of, even relatively light dust enters under the dirt-wiping sheet attached to the plate-like body and is captured there. Further, since the elastic protrusion near the center line that bisects the short side of the plate-like body is relatively hard to deform, it is suitable for scraping off dust adhering to the floor.

Further, among the elastic projections thus constructed, the projection in the vicinity of the center line projects particularly downward, and the attached wiping sheet curves downward convexly. Since the vicinity of the long side of the strip is easily separated from the floor surface, various kinds of dust easily enter under the wiping sheet.
