BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool to which a cleaning sheet is attached to clean a floor or furniture, and more particularly, to a cleaning tool that can effectively use the surface of a cleaning sheet in a wide range.

A disposable cleaning sheet formed of a nonwoven fabric or the like is used by being attached to a dedicated cleaning tool.

The cleaning tool generally has a plate-like support and a gripping portion connected to an upper surface of the support. The lower surface of the support is the cleaning operation side, and the cleaning sheet is installed on the lower surface, and both edge portions are wound around the upper surface of the support, and both edge portions are fixed on the upper surface.

The cleaning sheet attached to the lower surface of the support is applied to the surface to be cleaned, such as a floor surface, and the body is held so that the cleaning sheet is slid along the surface to be cleaned to catch dust or dirt on the surface to be cleaned by the cleaning sheet. To make it work.

However, since the lower surface of the conventional support body is a flat surface on the cleaning work side, dust and dirt are likely to accumulate in a portion of the cleaning sheet provided on the flat surface, covering the edge portion of the flat surface, but the inner side thereof. Dirt and dust are difficult to adhere to. Therefore, when a lot of dust and dirt adhere to the part which covers the said edge part, the cleaning effect of a cleaning sheet will fall, and the whole surface of a cleaning sheet cannot be utilized effectively.                         

In particular, relatively large dust, such as breadcrumbs scattered on the floor surface or the like, is likely to adhere to the portion covering the edge portion, and it is difficult to capture such large dust in the inner portion.

The cleaning tool disclosed in Japanese Patent No. 2981110 discloses a base body having cushioning properties such as urethane foam on the cleaning work side of the support, and the surface shape of the base body is in a direction perpendicular to the longitudinal direction. It is supposed that the amount of protrusion increases step by step toward the center in the direction. Japanese Unexamined Patent Application Publication No. 2001-299659 also discloses a cleaning tool provided with a cleaning cushion body formed of foamed urethane or the like on the cleaning work side of the support. The said cleaning cushion body is curved, The surface becomes the curved shape which becomes large in the protrusion amount gradually toward the center part in the direction in the direction orthogonal to the longitudinal direction of a support body. The surface of the cleaning cushion body is deformed into a flat surface when a cleaning sheet is attached to the cleaning cushion body and pressed against the surface to be cleaned such as a floor surface.

However, in the above conventional examples, since the surface of the support is in a shape in which the central portion in the direction protrudes in the direction orthogonal to the longitudinal direction, when the cleaning sheet is attached to the support and wiped off, dust is applied to the protruding portion. It is possible to adhere the dust, but since the amount of protrusion is constant toward the longitudinal direction of the support, a relatively large dust is extruded into the protruding portion when wiping, so that these relatively large dust cannot be effectively captured.

In addition, Japanese Patent Laid-Open No. 2001-299659 discloses that when the support is strongly pressed on the floor or the like, the surface of the cleaning cushion is deformed into a flat surface. The surface of the cleaning sheet cannot be effectively used over a wide range.

Moreover, although all the said prior art examples protrude from the center part in the direction orthogonal to a longitudinal direction, since this protrusion part continues uniformly in the longitudinal direction, the surface of the said cleaning work side should be provided in the floor surface. The support is unstable at the time. Therefore, when the floor surface or the like is polished, if the force applied from the body to the support is not well reduced, the support is extremely inclined, or in the worst case, the support tends to fall toward the front in the wiping direction.

The present invention solves the above-mentioned problems, and when the cleaning sheet is installed and wiped on the support, the present invention can be effectively used for wiping the entire surface of the cleaning sheet, and it is easy to catch relatively large dust. It aims at providing the cleaning tool.

Moreover, an object of this invention is to provide the cleaning tool which is rich in the stability at the time of moving a support body along a to-be-cleaned surface, such as a floor surface, and can stably slide a support along the said to-be-cleaned surface.

The present invention provides a cleaning tool having a support and a holding portion connected to the support or formed integrally with the support, the cleaning tool having a cleaning work surface on which at least one surface of the support can be provided.

The support has a shape in which the dimension in the first direction is longer than the dimension in the second direction, and has a central portion bisecting in the first direction.

The said cleaning work surface is provided with the protrusion top part which protruded the surface rather than the said center part in the both side parts separated by a predetermined distance in the 1st direction across the said center part, and the member which can elastically deform the predetermined area | region containing at least the protrusion top part. It is characterized by being formed by.

In the cleaning tool of the present invention, in the direction along the longitudinal direction (first direction) of the support, the cleaning work surface has a small protrusion amount at the center portion in the first direction and a large protrusion amount at both sides between the center portions. When the cleaning sheet is attached and the surface to be cleaned is cleaned, dust and dirt can easily be picked up by the center portion, and relatively large dust such as bread crumbs can be picked up by the central portion of the cleaning sheet.

Moreover, since the protruding tops are provided on both sides of the support working side of the support body in the first direction, the feeling of stability when the cleaning work side is placed on the floor surface or the like is excellent, and at least the protruding tops are elastically deformable. Therefore, when the force is applied to the gripping portion, the support can smoothly move the floor surface or the like.

For example, in the cross section cut | disconnected in the surface extended in a 1st direction past the said projection top part, the intersection of the said cleaning work surface and the said cross section is a concave curve which gradually reduces the protrusion amount from the said projection top part to the said center part.

With this arrangement, the area of the area deformed into a flat shape of the cleaning work surface can be adjusted by applying a force for pressing the support on the floor surface or the like, and the contact state between the central portion and the floor surface with a small protrusion amount can be adjusted. have. Therefore, dust and dirt can be effectively captured by the relatively large area of the cleaning sheet.

Further, in the cross section cut in the surface extending in the second direction past the protruding top portion, the intersection between the cleaning working surface and the cross section is a convex curve which gradually projects toward the middle of the cross section at both sides of the cross section. Preferably, the cross section between the cross section and the cleaning work surface when cut at the surface extending in the second direction from the protruding top portion to the center portion is directed toward the middle portion from both sides of the cross section. It is preferable that it is a convex curve which protrudes gradually.

If the cleaning work surface has the above-mentioned shape, the support body can be inclined appropriately in both directions of the reciprocating movement when the support body is reciprocated. When the cleaning sheet moves forward, the front region can be preferentially contacted with the surface to be cleaned. In the back movement, the rear region can be preferentially contacted with the surface to be cleaned, so that the surface of the cleaning sheet can be effectively used.

Or in the cross section cut in the surface extended in a 2nd direction past the said protruding top part, the intersection of the said cleaning work surface and the said cross section will protrude gradually toward the middle part from both sides of the said cross section, and will also be center part of the said cross section. It may be a convex curve in which the protrusion amount becomes small.

In this structure, the installation state of the support is stable when the support on which the cleaning sheet is mounted is installed on the floor surface.                     

Moreover, although the said cleaning work surface may be a continuous surface, the some area | region which can be elastically deformed is provided in the predetermined area | region containing at least the said protruding top part of the said support body, and the said cleaning work surface includes the front end surface of an individual processus | protrusion. It is also possible to make a virtual surface.

In the case where an elastically deformable projection is provided on the cleaning operation side, the individual projection can deform so that the virtual surface can be freely deformed, the followability to the surface to be cleaned can be improved, and it can be wiped off in a stable posture.

Moreover, the dimension of the said 1st direction is larger than the dimension of a 2nd direction. And the said 2nd direction (Y direction) is a main sliding direction of the said support body 2 at the time of a cleaning operation. Moreover, the support body 2 has the long side edge parts 2a and 2b extended in a 1st direction (X direction), and the short side edge parts 2c and 2d extended in a 2nd direction (Y direction). .

The support plate 5 is provided with a support plate 5 on the support side 4. The support plate 5 is formed by injection molding made of synthetic resin or die cast molding made of light alloy. A pair of support protrusions 5a and 5a are formed on the upper surface of the support plate 5, and an intermediate support 6 is formed on the shaft 6a between the support protrusion 5a and the support protrusion 5a. It is supported so that rotation is possible. The front end portion 8a of the gripping portion 8 is bifurcated in two, each arm is located on both sides of the intermediate support 6, and the front end portion 8a is supported by the shaft 6b. 6) is pivotally connected. As a result, the holding part 8 can fall toward both the X direction and the Y direction.

On the upper surface of the support plate 5, pressing members 7 and 7 are provided on both sides of portions where the support protrusions 5a and 5a are formed, respectively. The pressing members 7 and 7 are rotatably connected to the supporting plate 5 by proximal ends facing the supporting protrusions 5a and 5a by shafts 7a and 7a. As shown in Figs. 2 and 3, the pressing members 7 and 7 are able to fall into recesses 5b and 5b formed on the upper surface of the support plate 5. As shown in FIG. 1, when the cleaning sheet 20 is installed, the long sides 22 and 22 are pushed onto the upper surface of the support plate 5 with the pressing members 7 and 7 to clean the sheet 20. It can function as a fixing means for fixing the edge portion of the.

The cleaning function member 11 is provided on the cleaning work side 3 of the support 2. In the first embodiment, the cleaning function member 11 is integrally formed of an elastically deformable material, and is fixed in close contact with the lower surface of the support plate 5. The elastically deformable material constituting the cleaning function member 11 is foamed molded such as urethane foam, polyethylene foam or rubber sponge, or is an elastomer.

3 to 5, the cleaning function member 11 is fixed with the rear surface 11b being a flat surface and the rear surface 11b being in close contact with the lower surface of the support plate 5. Moreover, the surface 11a of the said cleaning function member 11 is a continuous curved surface which changes three-dimensionally, This surface 11a becomes a cleaning work surface.

When the center line extending perpendicular to the support plate 5 at the center of the rectangle of the support plate 5 is O-O, the surface 11a is rotationally symmetrical with respect to the center line O-O. The center line O-O is a center line that bisects the support 2 in both the first direction (X direction) and the second direction (Y direction). In FIG. 3, the point where the surface 11a and the centerline O-O intersect is shown as the central portion 12.

It is sectional drawing when. FIG. 4 is a cross-sectional view taken along the Y-Z plane passing through the protruding top portion 13 with the largest thickness of the cleaning function member 11 in FIG. 3.

The shape of the ridgeline of the surface 11a shown in the cross sections shown in FIGS. 4 and 5 is a plane symmetrical shape with respect to the X-Z plane passing through the center line O-O.                     

The ridgeline of the surface 11a shown in the cross section of Fig. 4 most protrudes downward in the midpoint (protrusion top 13) between the long side edge portion 2a and the long side edge portion 2b, It is a curve of the convex shape downwards from the said midpoint toward the said long side edge part 2a and the long side edge part 2b, and the protrusion amount becomes small gradually. Similarly, the ridgeline of the surface 11a shown as a cross section in FIG. 5 also protrudes downward in the midpoint (center portion 12) between the long side edge portion 2a and the long side edge portion 2b, and It is a curve of convex shape toward the said downward side from which a midpoint is gradually reduced toward the said long side edge part 2a and the long side edge part 2b.

In this embodiment, in the cross section of the YZ surface in every part of the area from the center portion 12 to the protruding top portion 13, the ridge line of the surface 11a appearing in the cross section has a long side edge portion 2a; It is the convex curve shape which protrudes downward in the midpoint with the long side edge part 2b, and the protrusion amount gradually becomes small toward the said long side edge part 2a and the long side edge part 2b from the said midpoint. .

The ridgeline of the surface 11a shown in the sectional view of FIG. 3 is a continuous line from the central portion 12 to the protruding top portion 13. In FIG. 3, the protrusion amount in the downward direction of the ridgeline is the smallest in the central portion 12, and the protruding top portion 13 and the protruding top portion 13 located on both sides of the central portion 12 as a starting point. The protrusion amount toward the downward direction of the ridge gradually increases. The ridge line is a concave curve between the protruding top 13 and the protruding top 13. In addition, between the protruding top portion 13 and the short side edge portion 2c, the amount of protrusion in the downward direction of the ridge line gradually decreases toward the short side edge portion 2c. This is the same even if it is between the other protruding top part 13 and the short side edge part 2d.

In addition, when the said support body 2 is cut | disconnected in the cross section of the XZ surface parallel to the cross section of FIG. 3, the protrusion below the ridgeline of the surface 11a of the cleaning function member 11 which appears in the cross section at any position of the cross section. The amount is the smallest at the same position as the central portion 12, and has a concave curved shape that gradually increases from the position toward the same position as the protruding top portion 13.

As shown in FIG. 3, the length from the said central part 12 to each short side edge part 2c, 2d in a 1st direction (X direction) is set to L0, respectively, from the said central part 12, respectively. When L1 is the shortest distance to the protruding tops 13 and 13 of L1, L1 is L0 / 2 or more and L0 or less is preferable, More preferably, L1 is (2/3) · L0 or more L0 or less If it is the said range, the attitude | position of the support body 2 can be stabilized when the said surface 11a is pressed to the to-be-cleaned surface, such as a floor surface, through the cleaning sheet.

Further, the elevation difference H in the Z direction between the central portion 12 and the protruding top portion 13 is preferably at least 1 mm and preferably at most 15 mm, more preferably at least 3 mm and at most 10 mm. When it is in the said range, when the said surface 11a is pressed by the floor surface etc. through the cleaning sheet | seat, and the surface 11a is pressed and deformed so that the surface 11a may become flat from the part of the protrusion top part 13, In the concave portion, the surface of the cleaning sheet and the surface to be cleaned may be lightly contacted, or a fiber or a thread may be present between the cleaning sheet and the surface to be cleaned to protrude from the surface of the cleaning sheet. As a result, relatively large dust can be captured by the surface sheet in the concave portion.

The cleaning sheet 20 attached to the support 2 of the cleaning tool 1 is rectangular and disposable. The cleaning sheet 20 is formed of a nonwoven fabric such as a spunlace nonwoven fabric so that dust and dirt can be captured by the raised fibers appearing on the surface of the nonwoven fabric. Alternatively, based on the nonwoven fabric, a plurality of fibers such as long fibers or fibers braided on the surface of the nonwoven fabric can be freely moved so that dust or dust can be caught between the fibers or between the yarns. will be.

As shown in FIG. 1, the said cleaning sheet 20 is the surface of the said cleaning function member 11 in the cleaning operation side 3 of the said support body 2, with the surface suitable for cleaning facing outward. It is installed in 11a). At this time, the short sides 21 and 21 of the cleaning sheet 20 are directed in parallel with the short side edge portions 2c and 2d of the support 2, and the long sides 22 and 22 of the cleaning sheet 20 are It is wound toward the support side 4 of the support 2. The long sides 22 and 22 of the cleaning sheet 20 are fixed by being sandwiched between the recesses 5b and 5b of the support plate 5 and the pressing members 7 and 7.

As shown in FIG. 1, the cleaning sheet 20 is attached to the cleaning surface 25 such as a floor surface with the cleaning sheet 20 attached to the support 2, and the support 2 is supported by the grip portion 8. ) Is pressed against the surface 25 to be cleaned, and the dust and dirt on the surface 25 to be cleaned can be captured from the surface of the cleaning sheet 20. The cleaning function member 11 compresses and deforms when the support body 2 is pressed against the surface to be cleaned 25 by the gripping portion 8, but at this time, the cleaning function member is first formed at the portions of the protruding top portions 13 and 13. 11 compressively deforms. Since the surface 11a is curved from the protruding top portions 13 and 13 to the central portion 12, the surface 11a is deformed into a planar shape by changing the pressing force of the holding portion 8. The area of the area | region made can be added or subtracted.

Further, in the middle portion of the protruding top 13 and the protruding top 13, the surface 11a is slightly separated from the surface to be cleaned 25 or the surface to be cleaned 25 through the cleaning sheet 20. It is in a lightly compressed state. Therefore, the cleaning sheet 20 located in the intermediate portion is in a state in which fibers or yarns on the surface of the cleaning sheet 20 are in contact with the surface to be cleaned 25, or a surface in which the surface of the cleaning sheet 20 is in light contact with the surface to be cleaned 25. Becomes Therefore, relatively large dust such as breadcrumbs existing on the surface of the surface to be cleaned 25 can be guided and captured to the central portion of the cleaning sheet 20 provided on the surface 11a.

In addition, a pressing force acts on the central portion of the support 2 from the grip portion 8, and protruding top portions 13 and 13 are provided on both sides separated from the grip portion 8 by a predetermined distance L1 and L1. Since the support body 2 is stably pressed against the surface 25 to be cleaned through the cleaning sheet 20, the support body 2 can slide on the surface 25 to be cleaned in a stable posture.

FIG. 6 is a side view showing a state in which the holding portion 8 is obliquely fell in the Y2 direction, holding the upper portion of the holding portion 8 and sliding the support 2 in the direction of arrow Y1 toward the second direction. FIG. 7 is a front view of the arrow VII shown in FIG. 6.

As shown in FIGS. 4 and 5, the surface 11a of the cleaning function member 11 provided on the support 2 has a long side edge portion 2a and a long side edge portion 2b. It is the convex curved shape which has the largest protrusion amount in the middle point of and becomes symmetrical on both sides of the Y direction with respect to the said middle point.

Therefore, as shown in FIG. 6, when the work pressing force F is obliquely given to the center part of the support body 2 from the holding part 8, the support body 2 will be a long side edge part facing forward of a sliding direction ( 2a) is inclined downward. At this time, in the vicinity of the protruding tops 13 and 13, since the front portion is preferentially pressed against the surface to be cleaned 25, as shown in Fig. 7, the surface 11a of the cleaning function member 11 Flat surfaces i (i) are formed at intervals in the X direction, and the cleaning sheet 20 positioned below the flat surfaces i (i) is in close contact with the surface to be cleaned 25. Since the flat surfaces i and i are located on both sides of the working point of the work pressing force F, the posture of the support 2 is stable, and the support 2 falls further forward from the posture of FIG. Evangelism is not good.

In this state, sliding in the direction of arrow Y1 tends to cause dust and dirt to adhere to the surface of the cleaning sheet 20 mainly on the flat surface i (i). Further, in the middle portion (ii) located in front of the sliding direction of the surface 11a and between the flat surface i and the flat surface i, fibers or yarns on the surface of the cleaning sheet 20 are removed. It exists in the state which contacts the to-be-cleaned surface 25, or the surface of the cleaning sheet | seat 20 is in the state which touched lightly the cleaned surface 25. Therefore, in this intermediate part (ii), it becomes easy to capture comparatively large dust, such as breadcrumbs.

Further, in the state of FIG. 6, when the grip portion 8 is pulled in the Y2 direction opposite to the above, the support 2 has a reverse side opposite to FIG. 6, that is, the long side edge portion 2b in front of the Y2 side. You will fall down. At this time, the flat part i (i) and the intermediate part ii are formed in the part on the Y2 side of the surface 11a of the cleaning function member 11 of the support body 2. As shown in FIG. And these parts can exhibit the cleaning function like when sliding to the arrow Y1 direction.

Therefore, by sliding the support body 2 in the Y1 direction and the Y2 direction alternately, the whole area | region of the surface of the cleaning sheet | seat 20 which covers the surface 11a of the cleaning function member 11 can be used efficiently, and a dust and dirt In addition, it can catch relatively large dust such as crumbs.

FIG. 8 shows a state in which a cleaning sheet 26 different from the cleaning sheet 20 is attached to the support 2 of the cleaning tool 1. The cleaning sheet 26 is formed by attaching a large number of fibers 28 in a free state to the substrate 27 provided on the surface 11a of the cleaning function member 11. The base material 27 is a nonwoven fabric containing thermoplastic fibers, and the fiber 28 is formed by loosening an aggregate of long fibers called TOW, and the base of the bundle of fibers 28 is formed on the base material 27. The cleaning sheet 26 is formed by attaching by heat fusion or the like. Alternatively, a plurality of yarns in which the fibers are braided may be fixed to the surface of the substrate 27 as a cleaning sheet.

When the cleaning sheet 26 is used, when the surface 11a of the cleaning function member 11 is pressed against the surface 25 to be cleaned via the cleaning sheet 26, the surface 25a of the cleaning sheet 26 is removed from the surface to be cleaned 25. In the remote part, the free fiber 28 or yarn is positioned between the base 27 and the surface 25 to be cleaned, and the base 27 is separated from the surface 25 to be cleaned. Therefore, relatively large dust such as bread crumbs can be trapped by the fibers 28 or yarns. In addition, the dust entangled in the fiber 28 or the thread does not easily fall on the surface to be cleaned 25.

FIG. 9 is a front view showing the cleaning tool 101 of the second embodiment of the present invention, and FIG. 10 is a side view of the cleaning tool 101 seen in the lateral X arrow direction.

In addition, in the Example shown to FIG. 9 and FIG. 10, the code | symbol is attached | subjected to the part of the structure same as the cleaning tool 1 of 1st Example shown in FIGS. 1-8, and the description is abbreviate | omitted.

As for the support body 102 of the cleaning tool 101 of 2nd Example, the cleaning function member 111 is attached to the cleaning operation side 3 of the support plate 5 to which the holding part 8 is connected. In this cleaning function member 111, a plate-shaped base 112 and a plurality of protrusions 113 protruding from the base 112 are integrally formed. The cleaning function member 111 is formed of an elastically deformable material such as natural rubber, synthetic rubber, or other elastomer, and the individual protrusions 113 are elastically deformable.                     

If the virtual continuous surface including the front end surface of each protrusion 113 of this cleaning function member 111 is called the surface 111a of the cleaning function member 111, this surface 111a will be shown in FIGS. It is a cleaning work surface of the same curved surface as the surface 11a of the cleaning function member 11 shown in figure.

Therefore, when the cleaning sheet 20 is attached to the support 102 of the cleaning tool 101 and wiped off the surface to be cleaned 25, the deformed state of the cleaning function member 111 and dust or dust The capturing function is almost the same as in the case of using the cleaning tool 1 of the first embodiment.

However, in the cleaning tool 101 shown in FIG. 9 and FIG. 10, since each protrusion 113 is easy to deform | transform, even if the cleaning function member 111 is formed from a comparatively durable material, the said surface 111a can be made free. It can be transformed.

Fig. 11 is a front view showing the cleaning tool 201 of the third embodiment of the present invention. 11, the same code | symbol is attached | subjected to the part of the structure same as the cleaning tool 1 of 1st Example shown in FIGS. 1-8, and the description is abbreviate | omitted.

In the cleaning tool 201 of the third embodiment, the distal end portion 8a of the gripping portion 8 is connected to the support 202. The support 202 has a cleaning function member 211 attached to the support plate (5). The cleaning function member 211 has a central function member 212 formed in a predetermined dimension on both the left and right sides in the X direction starting from the center 12, and side function members 213 and 213 are provided on both sides thereof. It is installed in close contact.                     

The central functional member 212 has the same cross-sectional shape of the Y-Z surface at any position along the X direction, and its cross-sectional shape is the same as that of the cleaning functional member 11 shown in FIG. 5. In addition, the cross-sectional shape of the side function members 213 and 213 is the same as the cross-sectional shape of the cleaning function member 11 shown in FIG. 4, and this side function member 213 and 213 is the 1st implementation shown in FIG.
