  The present invention will be described in detail based on the embodiments shown in the drawings.

  FIG. 1 is a configuration diagram of a cleaning sheet according to the first embodiment. The rectangular sheet 10 for cleaning is comprised from the outer sheet | seat part 11 which contact | connects the floor surface which is a to-be-cleaned surface, and the inner sheet | seat part 12 of the same shape piled up on the outer sheet | seat part 11 in use. And the outer sheet | seat part 11 and the inner sheet | seat part 12 have the incision part 13 by many slits mentioned later, but the non-incision area | region 14 in which the vicinity of the vertical side part of the both sides does not have a notch part Has been.

  The outer sheet portion 11 and the inner sheet portion 12 have the same size, for example, about 25 cm in length and about 15 cm in width. An appropriate size can be used for these sizes corresponding to the size of a head portion of a cleaning tool to be described later used for wiping and cleaning the floor surface.

  As the material of the outer sheet portion 11 and the inner sheet portion 12, a material such as a nonwoven fabric made of polyester, polypropylene, nylon or the like, a synthetic resin film, or a paper material is used. Further, it is desirable that the outer sheet portion 11 is made of a material that slides in contact with the floor surface and has flexibility and is easily fluffed. The outer sheet portion 11 is made of a material that is more flexible than the material of the inner sheet portion 12. For example, a soft nonwoven fabric is used for the outer sheet portion 11, and the inner sheet portion 12 is a stiff, hard nonwoven fabric. It is preferable that a nonwoven fabric is used for the outer sheet portion 11 and a synthetic resin film is used for the inner sheet portion 12.

  It is preferable to fix the vertical sides of the outer sheet portion 11 and the inner sheet portion 12 by welding, pressure bonding, adhesion, or the like so that the outer sheet portion 11 and the inner sheet portion 12 do not separate from each other even when stretched. . Further, during the use of the cleaning sheet 10, spot welding is performed at appropriate locations on the outer sheet portion 11 and the inner sheet portion 12 in order to prevent an extreme shift between the outer sheet portion 11 and the inner sheet portion 12. Or may be fixed with an adhesive or the like.

  Since the outer sheet part 11 and the inner sheet part 12 are overlapped and the cutting part 13 is formed by a cutting blade, the arrangement of the cutting part 13 is the same. FIG. 2 is a plan view of a part of the outer sheet portion 11, and a large number of slit-like cut portions 13 are cut in a straight line along the vertical direction. The end portions of these cut portions 13 are linearly connected by connecting portions 15 having a length shorter than that of the cut portions 13, and a plurality of cut rows are formed by the cut portions 13 and the connecting portions 15. These cut lines are formed in parallel at a predetermined interval. There are two types of cut rows, and the first cut row 16 and the second cut row 17 are alternately arranged in the horizontal direction.

  The first cut row 16 and the second cut row 17 are arranged adjacent to each other in parallel via the side edge pieces 18, and beside the cut portion 13 of the first cut row 16. The connection part 15 of the 2nd cutting row | line | column 17 is located. Further, the cut portion 13 of the second cut row 17 is located in the lateral direction of the connection portion 15 of the first cut row 16. As described above, the first and second cut rows 16 and 17 are alternately arranged, and the positions of the cut portions 13 of the first and second cut rows 16 and 17 are shifted, so that the outer sheet portion. 11. In the inner sheet portion 12, the cut portions 13 are arranged in a staggered manner.

  When the outer sheet portion 11 is extended in a direction perpendicular to the cutting direction, each cutting portion 13 expands in the lateral direction as shown in FIG. 3 and is transformed into a lip-shaped opening portion 19. Thus, the opening parts 19 by the 1st cutting row | line | column 16 and the 2nd cutting row | line | column 17 which expanded to the lip shape are arrange | positioned in zigzag form.

  Similarly to the outer sheet portion 11, the inner sheet portion 12 is also formed with a first notch row 16 and a second notch row 17 including a notch portion 13 and a connection portion 15. And if the inner sheet | seat part 12 is extended | stretched to a horizontal direction, the notch part 13 will become the opening part 19 extended in the lip shape, and the opening parts 19 will be arrange | positioned in zigzag form.

  For example, in the outer sheet portion 11 and the inner sheet portion 12, the length of the cut portion 13 is 10 mm, the length of the connection portion 15 is 4 mm, and the width of the edge piece portion 18 is 3 mm. Although depending on the material, the length of the cut portion 13 is, for example, about 7 to 15 mm, preferably about 10 mm, and the length of the connection portion 15 is, for example, about 3 to 5 mm, preferably about 4 mm. That is, the width of the edge piece 18 is preferably about 3 to 5 mm, for example.

  FIG. 4 shows a first modification of the outer sheet portion 11. As shown in FIG. 4A, the first cut row 16 and the second cut row 17 are alternately arranged, and only the long cut portion 20 is connected to the first cut row 16. Only the short cut portion 22 is arranged in the second cut row 17 via the connection portion 23. When the outer sheet portion 11 is extended in the lateral direction, a large opening 24 by the first cut row 16 and a small opening 25 by the second cut row 17 are formed as shown in FIG. The openings 24 and 25 are arranged in a staggered manner.

  FIG. 5 shows a second modification of the outer sheet portion 11. As shown in FIG. 5 (a), in the first cut row 16, long cut portions 20 and short cut portions 22 are alternately arranged via connecting portions 26 as if indicated by alternate long and short dash lines. The second cut row 17 is provided with every second cut portion 27 having an intermediate length. When the outer sheet portion 11 is stretched in the lateral direction, the first cut row 16 and the cut portion 27 are formed with alternating large openings 24 and small openings 25 as shown in FIG. A second cut row 17 having an opening 28 having an intermediate size is formed, and the openings 24, 25, 28 are arranged in a staggered manner.

  FIG. 6 shows a third modification of the outer sheet portion 11. As shown in FIG. 6A, the first cut row 16 is provided with intermediate length cut portions 27 at equal intervals, and the second cut row 17 is slightly slit in a diagonal direction. The cut part 29 cut | disconnected in the shape is arrange | positioned. When the outer sheet portion 11 is extended in the horizontal direction, as shown in FIG. 6B, the first cut row 16 of the intermediate size opening portion 28 and the lip shape in the oblique direction by the cut portion 29 are formed. The second cut row 17 in which the openings 30 are arranged is formed, and the openings 28 and 30 are arranged in a staggered manner.

  The opening pattern of the outer sheet portion 11 shown in FIG. 4 to FIG. 6 is the same as the opening pattern of the inner sheet portion 12 by forming the cut portion 13 with the cutting blade by overlapping the inner sheet portion 12 with two sheets. Become.

  Moreover, although the cutting pattern of FIG. 2, FIG. 4-FIG. 6 is uniformly formed with respect to the whole cutting pattern formation surface of the sheet | seat 10 for cleaning other than the non-cutting area | region 14, a cutting pattern The formation surface may be divided into a plurality of regions, and various cutting patterns shown in FIGS. 2 and 4 to 6 may be appropriately arranged in each region. Furthermore, the length of the cut portion 13 and the connection portion 15 is long, that is, a rough cut pattern, and the length of the cut portion 13 and the connection portion 15 is short, that is, a fine cut pattern is provided. The notch pattern may be appropriately arranged.

  For example, the cutting pattern forming surface is divided into three equal parts by a dividing line parallel to the vertical side, the cutting pattern shown in FIG. 2 is arranged in the center area, and the cutting pattern shown in FIG. Alternatively, the rough cutting pattern shown in FIG. 2 is arranged in the central area, and the fine cutting pattern shown in FIG. 2 is arranged in both end areas. In this way, it is also possible to use a combination of cutting patterns as appropriate according to the environment in which the cleaning sheet 10 is used.

  FIG. 7 is an explanatory diagram when the cleaning sheet 10 is attached to the cleaning tool 40. A handle 43 is rotatably attached to a synthetic resin flat substrate 42 of the head 41 of the cleaning tool 40.

  Each of the four corners of the base body 42 is made of a plate member having flexibility and elasticity, and is provided with a sheet holding portion 44 for holding the cleaning sheet 10. The pushing part 45 which cut | disconnected the plate-shaped member in the shape of a mountain is provided.

  When fixing the cleaning sheet 10 to the head portion 41, the bottom plate portion fixed to the bottom side of the base 42 so that the non-cut regions 14 of the cleaning sheet 10 are located on both sides of the long side of the base 42. It is necessary to arrange so as to cover the lower surface of 46. First, both ends of one non-cut region 14 of the cleaning sheet 10 are respectively pushed into and fixed to a pushing portion 45 on one long side of the base 42 as shown in FIG.

  After fixing one non-cutting region 14 of the cleaning sheet 10 to the pushing portion 45, the other non-cutting region 14 is extended in the direction of the arrow and wound around the bottom plate portion 46 as shown in FIGS. Then, while pulling the cleaning sheet 10, the other non-cut region 14 is attached by being pushed into the pushing portion 45 on the other long side of the base 42. In this way, the cleaning sheet 10 extended from the side of the base 42 to the bottom of the bottom plate 46 has a shape in which the notch 13 is transformed into the opening 19 as shown in FIG.

  FIG. 10 is an explanatory diagram in which a part of the outer sheet portion 11 of the cleaning sheet 10 in an expanded state is enlarged. When the cleaning sheet 10 is extended, the cut portion 13 is deformed to be deformed into a lip-shaped opening 19, the edge piece 18 in contact with the opening 19 is twisted and turned up, and the edge piece 18 is opened. It stands up toward the front side and the back side. A similar lip-shaped opening 19 is also formed in the inner sheet portion 12.

  FIG. 11 is a schematic conceptual view showing a part of a cross section of the cleaning sheet 10 when dust is collected by sliding the cleaning tool 40 with respect to the floor surface or the like. The outer sheet portion 11 and the inner sheet portion 12 are stretched and fixed to the head portion 41, so that the edge piece 18 on the periphery of the opening 19 rises and a space of the opening 19 is formed between the edge pieces 18. It becomes a three-dimensional structure.

  Since the outer sheet portion 11 and the inner sheet portion 12 have the same cutting pattern, the opening 19 is formed at substantially the same position when extended. However, the positions of the openings 19 of the outer sheet portion 11 and the inner sheet portion 12 are slightly shifted due to the difference in materials and the like, and dust is captured independently in the spaces in the respective openings 19.

  Moreover, if the materials of the outer sheet portion 11 and the inner sheet portion 12 are different, the type of garbage to be captured is also different. When the raised edge piece 18 of the outer sheet portion 11 having flexibility is slid with respect to the floor surface or the like, it is crushed and compressed by the head portion 41 in order to have flexibility. By this compression, a large number of fine irregularities are formed on the surface of the edge piece 18 and small dust S such as fine hair and dust is entangled. Further, the dust L having a diameter of, for example, 5 mm or more is fitted and held in the opening 19.

  When a material with waist is used for the inner sheet portion 12, the rising edge piece portion 18 is easy to retain its shape, and large dust L is easily fitted into the opening 19. Most of the dust that has entered the opening 19 of the outer sheet portion 11 is further pushed into the opening 19 of the inner sheet portion 12. Once the dust enters the space in the opening 19 of the inner sheet portion 12, the small dust S adheres to the edge piece 18 of the inner sheet portion 12, and the larger dust L becomes the opening of the inner sheet portion 12. 19 and is held. The dust that has reached the inner sheet portion 12 is caught by the edge piece portion 18 of the lower outer sheet portion 11 and is prevented from dropping from the inner sheet portion 12, so that it falls back into the opening 19 of the outer sheet portion 11 and returns. There are few things.

  Part of the dust that has entered the opening 19 of the inner sheet portion 12 is a medium-sized waste M having a diameter of about 2 to 4 mm and a small waste S that further pass through the opening 19 of the inner sheet portion 12 to form a bottom plate. It enters between the protrusion 46 a of the portion 46 and the inner sheet portion 12. Since these dusts are caught by the edge piece 18 of the inner sheet portion 12 and are prevented from falling, they remain in the space between the protrusion 46a of the bottom plate portion 46 and the inner sheet portion 12 and do not move.

  In the first embodiment, the opening pattern of the opening portion 19 by the outer sheet portion 11 and the inner sheet portion 12 has been described with reference to FIG. 3, but the size and direction can be changed even when the opening patterns according to FIGS. 4 to 6 are used. Garbage according to different openings is entangled.

  After use, the cleaning sheet 10 that sufficiently captures dust is pulled out from the sheet holding portion 44 of the head portion 41 and removed, and the waste is discarded. In the next cleaning, a new cleaning sheet 10 is attached to the head portion 41 and used.

  In Example 1, the cutting patterns of the outer sheet portion 11 and the inner sheet portion 12 were the same. However, in Example 2, the outer sheet portion 11 and the inner sheet portion 12 have different cut patterns. For example, the length of the connection portion 15 of the outer sheet portion 11, the distance between the first and second cut rows 16, 17, that is, the width of the edge piece portion 18 is the length of the cut portion 13 of the inner sheet portion 12. The length of the connecting portion 15 and the width of the edge piece portion 18 are set to be larger than each other.

  That is, the inner sheet portion 12 has a fine cut pattern by the cut portion 13, whereas the cut pattern of the outer sheet portion 11 is roughly formed. For example, as described above, in the outer sheet portion 11, when the length of the cut portion 13 is 10 mm, the length of the connection portion 15 is 4 mm, and the width of the edge piece portion 18 is 3 mm, the cut portion of the inner sheet portion 12 is It is conceivable that the length of 13 is 5 mm, the length of the connecting portion 15 is 2 mm, and the width of the edge piece 18 is 2 mm.

  In this case, the length of the cut portion 13 of the inner sheet portion 12 with respect to the outer sheet portion 11 is, for example, about 3 to 10 mm, preferably about 6 mm, and the length of the connection portion 15 is, for example, 1 to 3 mm. The width of the edge piece 18 is preferably about 1 to 3 mm, for example.

  FIG. 12 shows a cleaning sheet 10 when dust is collected by sliding a cleaning sheet 10 composed of an outer sheet portion 11 having a rough cutting pattern and an inner sheet portion 12 having a fine cutting pattern on the floor surface. It is a schematic conceptual diagram which shows a part of cross section.

  In the outer sheet portion 11 and the inner sheet portion 12, by changing the width of the edge piece portions 18 and 30e, when the opening portion 19 is formed by extension, the edge piece portion 18 stands up, so that the edge piece portion of the outer sheet portion 11 The standing height of 18 becomes larger than the edge piece 18 of the inner sheet portion 12, and the apparent thickness of the outer sheet portion 11 becomes larger than that of the inner sheet portion 12. Further, since the opening 19 of the outer sheet portion 11 has a larger area than the opening 19 of the inner sheet portion 12, the space formed by the opening 19 of the outer sheet portion 11 is the opening 19 of the inner sheet portion 12. It becomes bigger than the space by.

  When the rising edge piece 18 of the outer sheet portion 11 having flexibility is slid with respect to the floor surface or the like, it is crushed and compressed by the head portion 41. By this compression, a large number of fine irregularities are formed on the surface of the edge piece 18 and small dust S such as fine hair and dust is entangled.

  About the large garbage L, it catches by fitting in the opening part 19 of the outer side sheet | seat part 11, and the garbage M of the intermediate | middle size about 2-4 mm in diameter is pressed against the floor surface. It passes through the opening 19 of the outer sheet portion 11 and reaches the inner sheet portion 12 further.

  Small dust S such as fine hair or dust that has passed through the opening 19 of the outer sheet portion 11 is attached or entangled by the standing edge piece 18 of the inner sheet portion 12. Moreover, since the space by the opening part 19 of the inner sheet | seat part 12 is small compared with the outer sheet | seat part 11, the intermediate | middle size garbage M can be caught by fitting in the opening part 19 of the inner sheet | seat part 12. FIG.

  Even if the dust trapped in the space by the edge piece 18 and the opening 19 of the inner sheet portion 12 falls from the inner sheet portion 12 due to vibration or the like, it is caught by the opening portion 19 of the lower outer sheet portion 11 to the outside. The fall from the sheet part 11 is inhibited. Even if the large dust L that is pushed in without being fitted into the opening 19 of the outer sheet portion 11 is caught by the opening 19 of the inner sheet portion 12, it does not fall.

  The middle-sized garbage M and the small garbage S, which are a part of the dust that has entered the opening 19 of the inner sheet portion 12, further pass through the opening 19 of the inner sheet portion 12 as in the first embodiment. Then, it enters between the protrusion 46 a of the bottom plate portion 46 and the inner sheet portion 12. Since these dusts are caught by the edge piece 18 of the inner sheet portion 12 and are prevented from falling, they remain in the space between the protrusion 46a of the bottom plate portion 46 and the inner sheet portion 12 and do not move.

  In the second embodiment, even when the opening patterns according to FIGS. 4 to 6 are used in appropriate combinations with the outer sheet portion 11 and the inner sheet portion 12, garbage having a size corresponding to the opening portion having a different size and direction is used. It fits and is held without falling from the outer sheet part 11 and the inner sheet part 12.

  In the second embodiment, the cleaning sheet 10 including the outer sheet portion 11 having a rough cutting pattern and the inner sheet portion 12 having a fine cutting pattern has been described. You may use the sheet | seat 10 for cleaning which consists of the inner sheet | seat part 12 of a rough cutting pattern.

  In the first and second embodiments, the cleaning sheet 10 is used while being attached to the cleaning tool 40. However, for example, the cleaning sheet 10 that has been expanded can be cleaned while being held by hand.
