  The present invention will be described below based on preferred embodiments with reference to the drawings. The perspective view of one Embodiment of the cleaning sheet of this invention is shown by Fig.1 (a). FIG.1 (b) is a principal part enlarged view in Fig.1 (a). A cleaning sheet 100 shown in the figure is used by being attached to a cleaning head 30 in a cleaning tool 10 to be described later, for example. The cleaning sheet 100 has a cleaning base fabric 111 made of a nonwoven fabric. The cleaning base fabric 111 has two sets of opposing sides and has a substantially rectangular shape defined by these sides. The cleaning sheet 100 has a longitudinal direction X and a width direction Y orthogonal thereto. The cleaning base fabric 111 has a pair of first side portions 112 a and 112 b along the longitudinal direction X. In addition, the cleaning base fabric 111 has a pair of second side portions 113a and 113b along the width direction Y. The pair of first side portions 112a and 112b and the pair of second side portions 113a and 113b are orthogonal to each other at a substantially right angle, so that the cleaning base fabric 111 has a substantially rectangular shape. Further, the cleaning base fabric 111 has a first surface 114a and a second surface 114b located on the opposite side.

  The cleaning sheet 100 has a pair of sides of the two sets of sides of the cleaning base cloth 111 made of non-woven fabric, specifically, the same direction as the direction in which the pair of first side portions 112a and 112b extends (that is, the cleaning base fabric 111 Positioning members 120a and 120b arranged so as to extend in the longitudinal direction X). The positioning members 120a and 120b are disposed at the positions of the first side portions 112a and 112b along the set of first side portions 112a and 112b, respectively. Therefore, when viewed from the thickness direction of the cleaning base cloth 111, the cleaning base cloth 111 extends only from one side of the positioning members 120a and 120b and does not have a portion extending from the opposite side. Since the positioning members 120a and 120b are arranged at the positions of the first side portions 112a and 112b, when the cleaning sheet 100 is attached to a cleaning head of a cleaning tool to be described later and the cleaning operation is performed, the cleaning sheet 100 There is an advantage that it is possible to effectively prevent the positional deviation.

  As shown in FIG. 1B, the positioning members 120a and 120b are coupled to the cleaning base fabric 111 so as to abut on the first surface 114a of the first surface 114a and the second surface 114b of the cleaning base fabric 111. Part 121 is provided. The coupling portion 121 has a thin and elongated flat plate shape. The coupling part 121 has a first surface 121a and a second surface 121b located on the opposite side. The first surface 121a and the second surface 121b are substantially parallel. The coupling portion 121 has a pair of first side portions 122 a and 122 b that extend in the same direction as the longitudinal direction X of the cleaning base fabric 111 and face each other. The position of the first side part 122 a of the coupling part 121 is located at the same position as the first side part 112 a of the cleaning base fabric 111. That is, when viewed from the first surface 114 a side of the cleaning base fabric 111, the first side portion 122 a of the coupling portion 121 and the first side portion 112 a of the cleaning base portion 111 are disposed so as to overlap each other. The first side portion 122b of the coupling portion 121 is located on the inner side in the width direction Y than the first side portion 122a. As for the coupling | bond part 121, the whole area of the 2nd surface 121b is contact | abutting with the 1st surface 114a of the cleaning base fabric 111. FIG. The 2nd surface 121b of the coupling | bond part 121 and the 1st surface 114a of the cleaning base fabric 111 are joined so that attachment or detachment is impossible. Examples of such joining means include adhesion with an adhesive and heat fusion.

  The positioning members 120a and 120b have a protruding portion 123 that is connected to the coupling portion 121 described above. The protrusion 123 has a shape that can be detachably engaged with a portion to be engaged in the cleaning head 30 of the cleaning tool 10 to be described later. The protrusion 123 in the present embodiment has a thin and elongated flat plate shape. The protrusion 123 has a first surface 124a and a second surface 124b located on the opposite side. The first surface 124a and the second surface 124b are substantially parallel. The protruding portion 123 has a pair of first side portions 125 a and 125 b that extend in the same direction as the longitudinal direction X of the cleaning base fabric 111 and face each other. The protruding portion 123 is connected to the coupling portion 121 at the position in a state in which the position of the first side portion 125a coincides with the position of the second surface 121b of the coupling portion 121.

  The protruding portion 123 is connected to the coupling portion 121 such that the first surface 124 a and the second surface 124 b are substantially orthogonal to the first surface 121 a and the second surface 121 b of the coupling portion 121. Here, “substantially orthogonal” is an expression including orthogonal (90 degrees). As described above, the protruding portion 123 protrudes from the position of the first side portion 122a of the coupling portion 121 in the thickness direction Z of the cleaning base cloth 111, and is erected in a wall shape, as shown in FIG. , Has an L-shaped cross-sectional shape. Therefore, the protrusion 123 is substantially orthogonal to the first surface 114 a and the second surface 114 b of the cleaning base fabric 111. The protruding direction of the protruding portion 123 is a direction from the second surface 114b of the cleaning base fabric 111 toward the first surface 114a. Since the protruding portion 123 protrudes in the thickness direction Z of the cleaning base cloth 111, positional accuracy when the cleaning sheet 100 is attached to a cleaning tool described later is increased. Moreover, attachment can be performed reliably, and it is difficult to cause inconveniences such as the cleaning sheet 100 being detached from the cleaning tool during the cleaning operation. Specifically, since the protrusions 123 of the positioning members 120a and 120b are pushed into and engaged with the engagement target portion provided on the bottom surface of the cleaning head described later, the protrusions 123 are pressed against the cleaning tool during the cleaning operation. When pressure is applied, the protrusion 23 is pushed into the portion to be engaged by that amount, so that the engagement is further strengthened.

  As shown in FIG. 1B, the cleaning sheet 100 has positioning members 120a and 120b only on the first surface 114a of the cleaning base cloth 111, and the positioning member 120a on the second surface 114b of the cleaning base cloth 111. , 120b does not exist. No member is disposed on the second surface 114 b of the cleaning base fabric 111. Accordingly, since the cleaning base fabric 111 can be used for cleaning the entire second surface 114b, the entire area of the second surface 114b can be effectively utilized.

  The positioning members 120 a and 120 b having the coupling portion 121 and the protruding portion 123 are higher in rigidity than the nonwoven fabric that is a constituent material of the cleaning base fabric 111. Specifically, when the positioning members 120a and 120b are each alone and only one end in the longitudinal direction is fixed and held in the space in a horizontal state, the amount by which the other end of the positioning members 120a and 120b bends by its own weight is 3 mm. It is preferable to have the following rigidity. Since the positioning members 120a and 120b are higher in rigidity than the cleaning base cloth 111, operability when the cleaning sheet 100 is attached to a cleaning tool to be described later is improved. When the rigidity of the positioning members 120a and 120b is equal to or lower than the rigidity of the cleaning base cloth 111, the positioning members 120a and 120b are easily deformed, and the protrusions 123 of the positioning members 120a and 120b are formed. In addition, it is difficult to perform an operation of engaging with an engagement target portion provided in the cleaning tool 10, or after the engagement, when the cleaning tool 10 is used, it is easy to come off from the engagement target portion.

  In order to make the positioning members 120a and 120b more rigid than the cleaning base fabric 111, the positioning members 120a and 120b are made of, for example, a resin molded body, metal, wood, thick paper such as coated cardboard, or a composite material thereof. That's fine.

  In the cleaning sheet 100 of this embodiment, as shown to Fig.1 (a), the both ends along the longitudinal direction X of the positioning members 120a and 120b are the both ends along the longitudinal direction X of the cleaning base fabric 111, ie, 2nd. It is located at the positions of the side portions 113a and 113b. Instead, for example, as shown in FIG. 2, the lengths of the positioning members 120a and 120b extending along the first side portions 112a and 112b are shorter than the lengths of the first side portions 112a and 112b. The cleaning base fabric 111 may extend outward in the longitudinal direction X from both end portions along the longitudinal direction X of the members 120a and 120b to form extended portions 111a and 111b. Since the extending portions 111a and 111b protrude from the cleaning head in a state where the cleaning sheet 100 is attached to the cleaning head of the cleaning tool, the extending portions 111a and 111b are used using the protruding portions 111a and 111b. There is an advantage that it becomes easy to collect dust such as a rising corner from the floor to the wall.

  FIGS. 3A to 3E show another embodiment of the cleaning sheet 100. In the cleaning sheet shown in FIG. 3 (a), the positioning members 120a and 120b are connected to the connecting portion 121, which is a thin and elongated flat plate shape, as in FIG. 1 (b). The projection portion 123 has a thin and elongated flat plate shape. The coupling portion 121 and the protruding portion 123 are connected in a state where the protruding portion 123 is inclined inward in the width direction Y so that the angle θ formed by the two when viewed from the longitudinal direction X is less than 90. That is, the first surface 121a located on the opposite side of the second surface 121b coupled to the cleaning base fabric 111 in the coupling portion 121 and the first surface 124a in the projecting portion 123 intersecting the first surface 121a. They are connected so that the angle θ is less than 90. For example, the angle θ is preferably 45 degrees or more, and more preferably 50 degrees or more. Moreover, it is preferable that it is less than 90 degree | times, and it is preferable that it is 80 degrees or less. For example, the angle θ is preferably 45 degrees or more and less than 90 degrees, and more preferably 50 degrees or more and 80 degrees or less. When the protruding portion 123 is inclined, when the protruding portion 123 engages with an engagement target portion provided in the cleaning head of the cleaning tool, the engagement state is more difficult to be released due to the anchor effect, and cleaning is performed. Inconveniences such as the cleaning sheet 100 being detached from the cleaning tool during the operation are more effectively prevented.

  The positioning members 120a and 120b shown in FIG. 3 (b) have a hollow columnar shape, and more specifically, a hollow quadrangular columnar shape, and the height direction of the rectangular column is the cleaning base cloth 111. It consists of the thing arrange | positioned so that it may extend in the longitudinal direction X. One side surface 126 a of the hollow quadrangular column is coupled to the first surface 114 a of the cleaning base fabric 111. Therefore, the side surface 126 a functions as the coupling portion 121. The other three side surfaces 126 b, 126 c, 126 d in the hollow quadrangular column constitute a protruding portion 123 that protrudes in the thickness direction Z from the first surface 114 a of the cleaning base fabric 111. According to the present embodiment, the engagement state between the protrusion 123 and the engagement target portion provided on the cleaning head of the cleaning tool is strengthened, so that the cleaning sheet 100 is detached from the cleaning tool during the cleaning operation. Inconvenience is prevented more effectively.

  The positioning members 120a and 120b shown in FIG. 3B have a regular quadrangular prism shape in which the width direction Y and the thickness direction Z have the same length, but the lengths of the width direction Y and the thickness direction Z are the same. It can be different. For example, by making the thickness direction Z longer than the width direction Y, the positioning members 120a and 120b can be engaged more deeply with the engagement target portion, and the engagement state can be strengthened. In addition, the positioning members 120a and 120b used in the embodiment shown in FIG. 3B may be trapezoidal or parallelogram-shaped on the bottom surface of the quadrangular prism. Moreover, as long as it is a columnar shape, it is not limited to a square column, and may be a triangular column, a pentagonal column, a hexagonal column or the like.

  Positioning members 120 a and 120 b shown in FIG. 3C are hollow cylindrical shapes and are arranged in such a state that the height direction of the columns extends in the longitudinal direction X of the cleaning base cloth 111. A part 127 a of the side surface of the hollow cylinder is coupled to the first surface 114 a of the cleaning base fabric 111. Therefore, the side surface 127 a functions as the coupling portion 121. A portion 127 b other than the side surface 127 a in the hollow cylinder constitutes a protruding portion 123 that protrudes in the thickness direction Z from the first surface 114 a of the cleaning base fabric 111. According to the present embodiment, as in the embodiment shown in FIG. 3B, the engagement state between the protrusion 123 and the engagement target portion provided on the cleaning head of the cleaning tool becomes strong. Inconveniences such as the cleaning sheet 100 being detached from the cleaning tool during the operation are more effectively prevented.

  The positioning members 120a and 120b shown in FIG. 3 (d) are the same as the positioning members 120a and 120b shown in FIG. 3 (b) in that they are hollow quadrangular prisms, but the bottom surfaces of the quadrangular prisms are parallelograms. It differs in having it. One side surface 126 a of the hollow quadrangular column is coupled to the first surface 114 a of the cleaning base fabric 111. Therefore, the side surface 126 a functions as the coupling portion 121. The other three side surfaces 126 b, 126 c, 126 d in the hollow quadrangular column constitute a protruding portion 123 that protrudes in the thickness direction Z from the first surface 114 a of the cleaning base fabric 111. Then, side surfaces 126b and 126d constituting a part of the protruding portion 123 are inclined inward in the width direction Y. With this configuration, as in the positioning member shown in FIG. 3A, when the protruding portion 123 engages with an engagement target portion provided on the cleaning head of the cleaning tool, the engagement state is further released by the anchor effect. This makes it more difficult to prevent inconveniences such as the cleaning sheet 100 being detached from the cleaning tool during the cleaning operation.

  The positioning members 120a and 120b shown in FIG. 3D can be folded into a shape as shown in FIG. Thereby, when the cleaning sheet 100 is accommodated in the packaging material as a product, it can be accommodated in a compact manner. In use, the user can set the folded positioning members 120a and 120b to the cleaning head 30 of the cleaning tool 10 by restoring the three-dimensional shape as shown in FIG.

  The positioning members 120a and 120b used in the embodiment shown in FIGS. 3B and 3C are hollow prisms or cylinders. However, solid prisms or cylinders may be used instead. Good. That is, hollow or solid pillars can be used as the positioning members 120a and 120b. Further, the positioning members 120a and 120b used in the embodiment shown in FIGS. 3B and 3C have a cylindrical shape in which two bottom surfaces of the column body are opened. It may be a closed bottomed shape.

  4A and 4B show still another embodiment of the cleaning sheet 100. FIG. The cleaning sheet 100 shown in these drawings includes a cleaning base cloth 111 and a pair of positioning members 120a and 120b. The positioning members 120 a and 120 b are columnar members and are arranged in such a manner that the height direction of the columnar bodies extends in the longitudinal direction X of the cleaning base cloth 111. Specifically, the embodiment shown in FIG. 4A is a columnar member having a hollow quadrangular prism shape, and the height direction of the quadrangular column extends in the longitudinal direction X of the cleaning base cloth 111. It is the state of arrangement. The embodiment shown in FIG. 4 (b) is a columnar member having a hollow columnar shape, and is arranged in a state in which the height direction of the column extends in the longitudinal direction X of the cleaning base cloth 111. However, the positioning members 120a and 120b are not limited to hollow ones, and one or both of the positioning members 120a and 120b may be formed of a solid body.

  The positioning members 120 a and 120 b extend in parallel along the longitudinal direction X of the cleaning base fabric 111. The positioning members 120 a and 120 b are disposed at the positions of the first side portions 112 a and 112 b along the longitudinal direction X of the cleaning base fabric 111. The positioning members 120 a and 120 b have the same length, and both end portions thereof are located at the positions of the second side portions 113 b along the width direction Y of the cleaning base fabric 111. However, the length of the cleaning cloth 111 in the longitudinal direction X and the length of the positioning members 120a and 120b are not limited to the same, and for example, the positioning members 120a and 120b are similar to the cleaning sheet 100 of the embodiment shown in FIG. Is shorter than the length of the first side portions 112a and 112b, and the cleaning base fabric 111 extends outward in the longitudinal direction X from both ends along the longitudinal direction X of the positioning members 120a and 120b. The extending portion may be formed.

  The positioning members 120a and 120b have a transverse cross section, that is, the length of the cross section along the width direction Y in FIGS. 4A and 4B (the cross section orthogonal to the longitudinal direction of the positioning members 120a and 120b). It is larger than the thickness of the cleaning base fabric 111 made of The length of the cross-section of the positioning member refers to the length of the shortest line segment among the lengths of the line segments passing through the center of gravity of the figure in the two-dimensional figure of the cross-section. Therefore, when the cross-sectional shape of the positioning members 120a and 120b is a square as shown in FIG. 4A, it means the length of one side of the square. When the shape of the cross section of the positioning members 120a and 120b is a circle as shown in FIG. 4B, it means the diameter.

  The columnar members constituting the positioning members 120 a and 120 b are covered with the cleaning base cloth 111 throughout the entire side surfaces. The positioning members 120a and 120b covered with the cleaning base cloth 111 are directed from the first surface 114a of the cleaning base cloth 111 upward in the thickness direction Z of the cleaning base cloth 111 (that is, from the second surface 114b to the first side). A first protrusion 123a is formed by protruding toward the surface 114a. Similarly, the positioning members 120a and 120b are directed from the second surface 114b of the cleaning base fabric 111 downward in the thickness direction Z of the cleaning base fabric 111 (that is, from the first surface 114a to the second surface 114b). And projecting to form a second projecting portion 123b. Thus, in the embodiment described so far, in contrast to the protruding portion 123 protruding only on the first surface 114a side of the cleaning base cloth 111, in this embodiment, the cleaning base cloth 111 Protruding portions 123a and 123b protrude on both the first surface 114a and the second surface 114b. Since the protruding portions 123a and 123b protrude on both surfaces of the cleaning base cloth 111, the cleaning sheet 10 can use the first surface 114a of the cleaning base cloth 111 as a cleaning surface, and also clean the second surface 114. Can be used as a surface. In short, according to the present embodiment, there is an advantage that each surface of the cleaning base fabric 111 can be used for cleaning.

  In the embodiment shown in FIGS. 4A and 4B, if the positioning members 120a and 120b are covered with the cleaning base cloth 111, the positioning members 120a and 120b and the cleaning base cloth 111 are not coupled. It does not matter if they are connected or not.

  As the cleaning base fabric 111 used in each of the above embodiments, the same nonwoven fabric as conventionally used in the technical field can be used. Such nonwoven fabrics include, but are not limited to, spunlace nonwoven fabrics, air-through nonwoven fabrics, spunbond nonwoven fabrics, meltblown nonwoven fabrics, needle punched nonwoven fabrics, and resin bonded nonwoven fabrics. It is advantageous to use a non-woven fabric having a high degree of freedom of fiber from the viewpoint of satisfactorily entwining fibrous dust and granular dust. From this viewpoint, it is preferable to use a spunlace nonwoven fabric as the nonwoven fabric. Moreover, you may use any nonwoven fabric as a nonwoven fabric of the state which comprised the fiber raised on the nonwoven fabric surface by giving a raising process. The nonwoven fabric used as the cleaning base fabric 111 may be a composite material with other materials. For example, a nonwoven fabric combined with a mesh sheet can be used.

The basis weight of the cleaning base fabric 111 is preferably 10 g / m ² or more, more preferably 20 g / m ² or more, and more preferably 30 g / m ² or more from the viewpoint of dust collection performance and strength. Is even more preferred. Further, it is preferably 200 g / m ² or less, more preferably 150 g / m ² or less, and even more preferably 100 g / m ² or less. For example, the basis weight of the cleaning base fabric 111 is preferably 10 g / m ² or more and 200 g / m ² or less, more preferably 20 g / m ² or more and 150 g / m ² or less, and more preferably 30 g / m ² or more and 100 g / m ^{2. Even} more preferably, it is ² or less.

  Next, an example of the cleaning tool to which the cleaning sheet 100 of each embodiment mentioned above is attached is demonstrated. The cleaning tool 10 shown in FIGS. 5 to 8 has a floor, carpet floor, etc. as a surface to be cleaned, and removes dust particles (rice, confectionery waste, earth dust, sand, etc.), hair, and cotton dust on the surface to be cleaned. It is something to collect. The cleaning tool 10 has a dust container 40 in a cleaning head 30 provided at the tip of the handle 20, front and rear side openings 41 (41 F, 41 R) provided in front and rear of the dust container 40, and those It has cleaning rolls 50 (50F, 50R) before and after closing the side opening 41.
