JP2004-230083

  In Patent Document 1, an adhesive roll is rotatably supported on roll support shafts provided on both sides of a window frame of a frame.

  Therefore, when exchanging the adhesive roll, it is necessary to remove the adhesive roll from the roll spindle while peeling the adhesive roll adhering to the scraping roll or the rotating body from the adhesive counterpart, which is complicated.

  In addition, when the pressure-sensitive adhesive roll is composed of a pressure-sensitive adhesive sheet take-up roll and peels and removes one turn of the used pressure-sensitive adhesive sheet, the sheet end of the pressure-sensitive adhesive roll is pulled and the pressure-sensitive adhesive roll is scraped up. One rotation is made on the roll and the rotating body. However, the adhesive roll adheres to the scraping roll and the rotating body, and it is necessary to forcefully rotate the adhesive roll against the scraping roll and the rotating body that are stopped by friction with the floor surface. The nature is bad.

  An object of the present invention is to enable easy replacement of an adhesive roll in a cleaning tool.

  Another object of the present invention is to make it possible to peel a used adhesive sheet of an adhesive roll while supporting the adhesive roll on a cleaning tool.

According to the first aspect of the present invention, the cleaning roll and the adhesive roll above the cleaning roll are rotatably supported on the frame. The cleaning roll guides dust taken from the floor surface by rotation to the adhesive roll. Disposed so as to rotate together with the cleaning roll while in contact with the outer periphery of the cleaning roll, and having an isolation means for maintaining the cleaning roll and the adhesive roll supported by the frame and switching between the contact state and the non-contact state of both rolls A cleaning tool that rotatably supports the cleaning roll inside the window frame of the frame and pivots the base end of the adhesive roll cover on which the adhesive roll is rotatably supported to one side of the window frame of the frame. supported, and swingable between the open position rising from the window frame position and the frame is closed lie down the pressure-sensitive adhesive roll cover on the window frame of the frame around its base end portion, the adhesive roll cover The adhesive roll cover covers the adhesive roll when positioned at the closed position, contacts the adhesive roll with the cleaning roll, and faces the external roll when positioned at the open position, and the adhesive roll becomes the cleaning roll. It is designed to be non-contact.

  According to a second aspect of the invention, in the first aspect of the invention, the pressure-sensitive adhesive roll is constituted by a pressure-sensitive adhesive sheet take-up roll.

(a) A separating means for maintaining the state where the cleaning roll and the adhesive roll are supported by the frame and switching between the contact state and the non-contact state of both rolls is provided. Therefore, when exchanging the adhesive roll, the adhesive roll can be removed from the cleaning roll by the separating means, and then the adhesive roll can be easily removed from the roll spindle.

(b) When the used adhesive sheet of the adhesive roll is peeled and removed while the adhesive roll is supported on the cleaning tool, the adhesive roll is brought out of contact with the cleaning roll by the separating means, and then the sheet end of the adhesive roll is pulled. For example, the pressure-sensitive adhesive roll rotates with respect to the roll spindle, and the used pressure-sensitive adhesive sheet for one turn can be peeled and removed. At this time, since the pressure-sensitive adhesive roll is isolated from the cleaning roll and can be smoothly rotated, the peelability of the used pressure-sensitive adhesive sheet is good.

(c) By covering the adhesive roll with the adhesive roll cover, it is possible to isolate the adhesive roll from dust, and to prevent a person's fingers and articles from being inadvertently touching the adhesive roll. And by the opening operation of the adhesive roll cover for replacement | exchange of an adhesive roll or the update of an adhesive sheet, an adhesive roll can be removed from a cleaning roll immediately, and an adhesive roll can be rotated easily.

( Reference Example 1)
The cleaning tool 10 collects trash on the cleaning surface such as the floor surface 1 such as large and small particle trash or hair tangled around fibers such as carpets. As shown, a support arm 13 is coupled to the tip of the handle 11 via a left / right swing shaft 12 so as to be swingable in the left / right direction intersecting the cleaning direction, and the front / rear swing shaft 14 is connected to both arm portions 13A of the support arm 13. The frame 15 is supported so as to be swingable in the front-rear direction along the cleaning direction.

  The cleaning tool 10 is provided with hard left and right front wheels 21 and left and right rear wheels 22 (grounding portions) that are in rolling contact with the floor surface 1 so as to be rotatable on both front and rear sides of the frame 15. As shown in FIG. 3, the rotating shaft 21A of the front wheel 21 is supported by a long hole 15A provided along the front and rear in the cleaning direction of the frame 15, and the front wheel 21 is moved to the rear side of the long hole 15A when moving forward and when moving backward. It is positioned on the front side of the long hole 15A. The cleaning tool 10 may be provided with a hard shoe that is in sliding contact with the floor surface 1 as a grounding portion.

  In the cleaning tool 10, an elastic pressing roll 30 (cleaning roll) and an elastic scraping roll 40 are arranged in parallel on the front and rear along the cleaning direction of the frame 15, and both the rolls 30 and 40 are grounded to the front wheel 21 and the rear wheel 22. The diameter is larger than the line (the straight line connecting the grounding point of the front wheel 21 and the grounding point of the rear wheel 22) to the outside (the side entering the floor).

  The pressing roll 30 is disposed on the dust introduction side of the frame 15, and is in a range in which the pressing roll 30 is in contact with the floor surface 1 over almost the entire region sandwiched between the left and right front wheels 21 and the rear wheel 22 in the lateral direction perpendicular to the cleaning direction. Is supported by the rotating shaft 21 </ b> A of the front wheel 21 supported by the wheel 1, and rolls while contacting the floor surface 1. The pressing roll 30 is coaxially driven by the rotational force of the front wheel 21 and may be fixedly coupled to the rotating shaft 21A of the front wheel 21, but is rotated by rubbing with respect to the floor surface 1 and the scraping roll 40. In order to prevent this, the rotary shaft 21A is driven in frictional contact. The pressing roll 30 is made of a material (elastic flexible material) capable of elastically bending the surface in contact with the floor surface 1. A cylindrical sponge roll, a flexible plastic roll, a rubber roll, a brush roll, or the like can be adopted as the presser roll 30, but a cushion roll such as a sponge roll is optimal.

  The scraping roll 40 is disposed on the side opposite to the dust introduction side of the pressing roll 30 of the frame 15 and is supported on both sides of the frame 15 in a range aligned with the pressing roll 30 in the lateral direction perpendicular to the cleaning direction. It is supported by the rotating shaft 41 </ b> A of the left and right transmission wheels 41 and is in rolling contact with the floor surface 1. The left and right transmission wheels 41 are rotatably supported behind the left and right front wheels 21, and are driven by the front wheels 21 in contact with the front wheels 21 during forward movement (FIG. 2). The pressing roll 30 driven coaxially to the front wheel 21 and the scraping roll 40 driven to the front wheel 21 via the transmission wheel 41 rotate opposite to each other. As described above, the front wheel 21 at the time of reverse movement moves to the front side of the long hole 15A provided in the frame 15 and moves away from the transmission wheel 41, so that the transmission wheel 41 is not driven and driven (FIG. 3). . The scraping roll 40 is made of a material (elastic flexible material) capable of elastically bending at least the surface in contact with the floor surface 1. As the scraping roll 40, a cylindrical sponge roll, a flexible plastic roll, a rubber roll, a brush roll, or the like can be adopted. However, the brush roll is optimal in combination with the sponge roll constituting the pressing roll 30.

  The cleaning tool 10 makes the sum of the radius of the press roll 30 and the radius of the scraping roll 40 larger than the distance between the axes of both the rolls 30 and 40 supported by the frame 15, and as a result, the both rolls 30 and 40 are Contact portions are formed which are brought into contact with each other by elastic deflection deformation of the contact portions, and the height from the lower end of the contact portion to the floor is made smaller than the size of dust to be taken in by the pressing roll 30 (FIG. 1).

  At the time of cleaning in which the front wheel 21 and the rear wheel 22 are brought into rolling contact with the floor surface 1, the cleaning tool 10, as shown in FIG. 1, holds the press roll 30 and the scraping roll 40 in contact with the floor surface 1 at the contact portion with the floor surface 1. The large outer diameter portion protruding from the grounding wire of the front wheel 21 and the rear wheel 22 is largely elastically deformed, and both the rolls 30 and 40 are rotated in opposite directions at substantially the same peripheral speed. Both rolls 30 and 40 bite into each other and are greatly elastically deformed and bitten with respect to the floor surface 1, and the diameter of the scraping roll 40 is reduced with respect to the press roll 30, and the meeting point A of the two rolls 30 and 40. The dead space (gap) having a triangular shape in side view is substantially eliminated between the roll surface 1 and the floor surface 1, and both rolls 30 and 40 meet on the floor surface 1 with almost no gap.

  Accordingly, when cleaning is performed by the cleaning tool 10, the pressing roll 30 presses the dust on the floor surface 1 so as not to escape while rotating without rubbing significantly against the floor surface 1. The dust on the floor surface, which is guided backward by deforming the press roll 30, is sandwiched between the press roll 30 and the scraping roll 40, and guided by the rotation of both rolls 30, 40 to the upper side of the floor. When the force is released, the force is collected by the elastic restoring force of the press roll 30 and / or the scraping force of the scraping roll 40. That is, the dust on the floor surface pressed by the pressing roll 30 is sandwiched between the two rolls 30 and 40 at the meeting point A between the pressing roll 30 and the scraping roll 40 and picked up from the floor surface 1. While being pushed out by the elastic restoring force of the presser roll 30 at the separation point B of both the rolls 30, 40, it is blown off by the elastic restoring force of the scraping roll 40. This dust is collected in a dust collector 50 described later.

  As shown in FIG. 2, the cleaning tool 10 has a diameter of the pressing roll 30 of 40 mm (the diameter of the front wheel 21 is 34 mm), a diameter of the scraping roll 40 is 25 mm, and the pressing roll 30 and the scraping roll 40 as shown in FIG. The distance L between the shafts is 25 mm, the diameter of the transmission wheel 41 is 16 mm, and the distance H between the central axis of both the rolls 30 and 40 and the floor when the both rolls 30 and 40 are bitten into the floor is 8 to 10 mm. To do.

  When the cushion 10 is used as the pressing roll 30, the cleaning tool 10 may be such that the thickness of the cushion portion on the surface of the pressing roll 30 is preferably 5 mm or more, and the entire portion excluding the shaft core of the pressing roll 30 is used as the cushion portion. .

  As shown in FIG. 1, the cleaning tool 10 has a dust collector 50 (dust collector) disposed at the rear of the frame 15 in the cleaning direction with respect to the scraping roll 40. The dust collector 50 includes a box-shaped dust receiver 51 integrated with the frame 15, a lower dust stopper 52 is raised from a lower front portion of the dust receiver 51, and an upper dust stopper 53 is provided at the upper front. The lower dust stopper 52 has an arc shape along the outer periphery of the scraping roll 40, and the upper dust stopper 53 has an arc shape along the outer periphery when the rotation cover 62 of the adhesive roll holder 60, which will be described later, comes into rotation. The lower edge of the stopper 53 is close to the outer periphery of the pressing roll 30. A space between the upper edge of the lower dust stopper 52 and the lower edge of the upper dust stopper 53 is defined as a dust feeding interval (dust inlet) 54. Garbage blown off by the pressing roll 30 and the scraping roll 40 is collected in the garbage receiving portion 51 via the dust feeding port 54.

  The dust collector 50 is provided with a rear lid 55 at the rear opening 51A of the dust receiver 51 so as to be freely opened and closed. The rear cover 55 supports a lower end portion of a support shaft 55 </ b> A provided at a lower rear portion of the dust receiving portion 51 so as to be swingable, and includes a locking lever 56 at the upper end portion. The locking lever 56 is locked to a locking claw 57 provided in the upper rear part of the dust receiving portion 51 by a spring force (not shown) (FIGS. 1 and 6), and is rotated by manual operation to Is released (FIG. 8). When collecting dust in the dust collector 50, the rear opening 51 </ b> A is closed by the rear lid 55, and when discharging the dust, the rear lid 55 opened by the locking lever 56 is opened by the rear lid 55. 51A is opened (FIGS. 7 and 9), and dust is removed from the rear opening 51A. The dust receiver 51, the rear lid 55, etc. of the dust collector 50 are preferably made of a transparent material that allows the dust collection state to be visually recognized.

In the cleaning tool 10, an adhesive roll holder 60 is provided on the upper portion of the pressing roll 30 in the frame 15, and the adhesive roll 70 is placed on the pressing roll 30. The pressure-sensitive adhesive roll 70 is placed on the pressure roller 30 while being set on both roll support shafts 63 and 64 (described later) of the pressure-sensitive adhesive roll holder 60, and is placed on the pressure roller 30 and is in contact with the outer periphery of the pressure roller 30 during cleaning. Rotate around 30 turns. The pressure-sensitive adhesive roll 70 includes a structure of a winding roll of the pressure-sensitive adhesive sheet 71 or a structure in which the surface is made of a sticky elastomer, and the surface can be cleaned and reused. The pressure-sensitive adhesive roll 70 of this reference example is constituted by a winding roll in which the pressure-sensitive adhesive sheet 71 is wound around a core 72 and the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet 71 can be unwound and cut off. The pressure-sensitive adhesive roll 70 adheres and captures dust such as hair wound around the surface of the pressure roll 30 while rotating with the rotation of the pressure roll 30.

  As shown in FIGS. 14 and 15, the adhesive roll holder 60 includes a window frame 61 having a substantially rectangular frame shape over a range aligned with the pressing roll 30 in the lateral direction perpendicular to the cleaning direction on the front upper surface of the frame 15. The rotation cover 62 is rotatably provided on the inner surfaces of the left and right side portions of the window frame 61. The rotary cover 62 has a substantially halved cylindrical body made of a transparent material such as a semicircular arc-shaped cross section or a U-shaped cross section, and has both side walls. A fixed-side roll support shaft 63 is provided on one of the left and right side walls of the rotary cover 62, and a slide-side roll support shaft 64 is provided on the other left and right side walls. The core 72 of the adhesive roll 70 can be freely rotated on both roll support shafts 63, 64. To support.

  In the adhesive roll holder 60, the fixed-side roll support shaft 63 passes through one side wall of the rotation cover 62, and the fixing pin 65 inserted through the one side wall of the window frame 61 is screwed to the fixed-side roll support shaft 63. Then, the fixed roll support shaft 63 is fixed. The rotation cover 62 has a gap between the window frame 61 and the fixed-side roll support shaft 63 and can rotate lightly with respect to the fixed-side roll support shaft 63. The slide-side roll support shaft 64 passes through the other side wall of the window frame 61 and the other side wall of the rotary cover 62. After inserting the spacer 66, the coil spring 67, and the slide plate 68 into the through end, the fixing pin 69 is inserted. The slide side roll support shaft 64 is screwed to fix the slide side roll support shaft 64.

  The adhesive roll holder 60 constitutes an isolating unit that maintains the state in which the pressing roll 30 and the adhesive roll 70 are supported by the frame 15 and switches between the contact state and the non-contact state of both the rolls 30 and 70. Specifically, the adhesive roll holder 60 has a pin 65 and a support shaft 64 as rotation support shafts of the rotation cover 62 that are concentric with the roll support shafts 63 and 64, and the rotation cover 62 is rotated around those rotation support shafts. Open and close can be rotated.

  As shown in FIGS. 10 and 12, the rotary cover 62 is closed so that the front edge flange 62 </ b> A having a half-arc cross section or a U-shaped cross section of the rotary cover 62 abuts on the front upper edge of the window frame 61. In the state positioned, the window frame 61 is closed, the adhesive roll 70 supported by the two roll support shafts 63 and 64 is covered, and the two rolls 30 and 70 are brought into contact. On the other hand, as shown in FIGS. 11 and 13, the window frame 61 is opened and the rotation cover 62 is pressed while the front edge flange 62 </ b> A of the rotation cover 62 is positioned at the open position where it abuts against the upper rear edge of the window frame 61. It is interposed between the roll 30 and the adhesive roll 70 so that the adhesive roll 70 is exposed to the outside world, both the rolls 30 and 70 are brought into a non-contact state, and the core 72 of the old and new adhesive roll 70 is attached to and detached from both roll support shafts 63 and 64. Alternatively, the used pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 set on both roll support shafts 63 and 64 can be peeled and removed. That is, when the rotary cover 62 moves from the closed position to the open position, the rear edge portion opposite to the front edge flange 62A of the rotary cover 62 is sunk into the outer periphery of the upper portion of the pressing roll 30, thereby causing elastic deflection deformation. It is interposed between the upper outer periphery of the pressed presser roll 30 and the adhesive roll 70. That is, the rotary cover 62 deforms the pressing roll 30 and switches both the rolls 30 and 70 between a contact state and a non-contact state. As a result, when the rotation cover 62 is opened and the used one turn of the pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 set on both roll spindles 63 and 64 is to be peeled and removed, the pressure-sensitive adhesive sheet 71 Can be smoothly peeled without sticking to the outer periphery of the pressing roll 30. The peeled end of the pressure-sensitive adhesive sheet 71 can be cut using the front edge or the rear edge of the rotary cover 62.

  As shown in FIG. 14, the adhesive roll holder 60 presses the slide plate 68 against the flange side of the fixed pin 69 with the coil spring 67 in a state where the adhesive roll 70 is set on both roll support shafts 63 and 64. The distance from the one side wall of the window frame 61 opposite to this is reduced, and the axial displacement in which the adhesive roll 70 is detached from the fixing pin 69 is prevented. On the other hand, when the adhesive roll 70 is removed from both roll spindles 63 and 64, the coil spring 67 is compressed by pushing the adhesive roll 70 toward the slide plate 68 (P1) as shown in FIG. Is slid to the other side wall side of the window frame 61, the distance between the slide plate 68 and one side wall of the window frame 61 opposite to the slide plate 68 is increased, and one end of the adhesive roll 70 on the fixed side roll support shaft 63 side is By lifting (P2), the adhesive roll 70 is removed (the same applies to the case where the adhesive roll 70 is attached to both roll support shafts 63 and 64).

The cleaning operation by the cleaning tool 10 is performed as follows.
(1) When the front wheel 21 and the rear wheel 22 are pressed against the floor surface 1 by the pressing operation force applied to the handle 11 by the cleaning tool 10 and moved forward, the front wheel 21 moves to the rear side of the long hole 15A of the frame 15 and is transmitted. While firmly contacting the wheel 41, the pressing roll 30 is directly rotated by the rotational force of the front wheel 21, and the rotational force of the front wheel 21 is transmitted to the scraping roll 40 via the transmission wheel 41, and the scraping roll 40 is opposite to the pressing roll 30. Rotate in the direction.

  At this time, the two rolls 30, 40 bite each other, and the outer diameter portions of both rolls 30, 40 contacting the floor 1 are greatly elastically deformed, and in particular, the sponge that moves backward together with the rotating shaft 21 </ b> A of the front wheel 21. The presser roll 30 is dragged rearward by contact with the floor surface 1 so that there is almost no gap with the scraping roll 40.

  Thereby, the dead space having a triangular shape in a side view is substantially eliminated between the meeting point A of both the rolls 30 and 40 and the floor surface 1, and the both rolls 30 and 40 meet on the floor surface 1 with almost no gap.

  (2) According to the above (1), the pressing roll 30 presses the dust on the floor surface 1 so as not to escape while rotating without rubbing greatly against the floor surface 1. The dust on the floor surface 1 pressed by the presser roll 30 is sandwiched between the rolls 30 and 40 at the meeting point A of the presser roll 30 and the scraping roll 40 and picked up from the floor surface 1. While being pushed out by the elastic restoring force of the presser roll 30 at the separation point B of the rolls 30 and 40, it is blown off by the elastic restoring force of the scraping roll 40, and is sent to the dust receiving part 51 of the dust collecting part 50 via the dust feeding port 54. It is collected.

At the same time, dust such as hair wound around the surface of the pressing roll 30 is caught and caught by the pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 on the pressing roll 30.
As a result, slender garbage such as small paper pieces and spaghetti is also collected.

  (3) When the cleaning tool 10 is retracted, the pressing operation force from the floor surface 11 is released, and the pressing roll 30 and the lifting roll 40 cause the repulsive force against the floor surface 1 to lift the front wheel 21 from the floor surface 1; The front wheel 21 moves to the front side of the long hole 15A of the frame 15 and moves away from the transmission wheel 41, so that the pressing roll 30 and the scraping roll 40 do not rotate in reverse. Accordingly, the dust taken into the dust receiving portion 51 of the dust collecting portion 50 is not discharged from the dust receiving portion 51 due to the reverse rotation of the pressing roll 30 and the scraping roll 40.

  (4) When it is visually confirmed that a large amount of dust has accumulated in the dust receiver 51 of the dust collector 50, the rear cover 55 is opened to remove dust from the rear opening 51A of the dust receiver 51.

  (5) When it is visually confirmed that a large amount of dust has been captured on the pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70, the rotation cover 62 of the pressure-sensitive roll holder 60 is opened, and the pressure-sensitive adhesive sheet 71 for one turn is peeled off and removed. Expose the surface.

According to this reference example , the following operational effects are obtained.
(a) An adhesive roll holder 60 (separating means) that switches between a contact state and a non-contact state of both rolls 30 and 70 while maintaining the state where the pressing roll 30 and the adhesive roll 70 are supported by the frame 15 is provided. Therefore, when exchanging the adhesive roll 70, the adhesive roll 70 can be removed from the press roll 30 by the adhesive roll holder 60 (isolation means), and then the adhesive roll 70 can be easily removed from the roll spindles 63 and 64. .

  (b) When the used pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 is peeled and removed while the pressure-sensitive adhesive roll 70 is supported on the cleaning tool 10, the pressure-sensitive adhesive roll 70 is not contacted from the pressing roll 30 by the pressure-sensitive roll holder 60 (separating means). Then, if the sheet end of the adhesive roll 70 is pulled, the adhesive roll 70 rotates with respect to the roll support shafts 63 and 64, and the used adhesive sheet 71 for one turn can be peeled and removed. At this time, since the adhesive roll 70 is isolated from the pressing roll 30 and can be smoothly rotated, the peelable removal property of the used adhesive sheet 71 is good.

  (c) The adhesive roll holder 60 (separating means) can easily switch between a contact state and a non-contact state between the press roll 30 and the adhesive roll 70 by deforming the press roll 30.

  (d) By covering the adhesive roll 70 with the rotating cover 62, the adhesive roll 70 can be isolated from dust, and it is possible to prevent a person's fingers and articles from touching the adhesive roll 70 carelessly. Then, the adhesive roll 70 can be immediately separated from the pressing roll 30 by the opening operation of the rotation cover 62 for replacing the adhesive roll 70 or updating the adhesive sheet, and the adhesive roll 70 can be easily rotated.

In addition, according to this reference example , there also exist the following effects.
(a) A cushion roll is used as the presser roll 30, and large and small trash having the maximum diameter of the cushion part of the presser roll 30 is wrapped by deformation of the cushion part, guided to the side of the scraping roll 40, and pressed. Since it is sandwiched between the roll 30 and the scraping roll 40, it is possible to collect various kinds of garbage on the cleaning surface without getting them.

  (b) The pressing roll 30 and the scraping roll 40 form a contact portion that bites into contact with each other, and the height from the lower end of the contact portion to the floor is smaller than the size of the dust to be taken in. Accordingly, the dust is always sandwiched between the contact portions of the pressing roll 30 and the scraping roll 40, and the dust of a certain size or more on the floor surface can be collected.

  (c) By reducing the diameter of the scraping roll 40 relative to the pressing roll 30, the gap between the scraping roll 40, the pressing roll 30 and the floor surface is reduced, and dust on the floor surface is separated from the pressing roll 30. The scraping roll 40 facilitates pinching.

  (d) Since the scraping roll 40 and / or the cushion roll bite into the floor surface by elastic deformation, the dust on the floor surface is easily sandwiched between the pressing roll 30 and the scraping roll 40.

  (e) Since the adhesive roll 70 is disposed above the pressing roll 30 and both the rolls 30 and 70 are in contact with each other and rotate together during cleaning, the adhesive roll 70 is rotated along with the rotation of the pressing roll 30. Can be driven. The drive roll of the adhesive roll 70 is not particularly required. A large space for collecting dust such as the dust collector 50 can be provided.

  (f) The dust sandwiched between the pressing roll 30 and the scraping roll 40 and bounced off can be collected in the dust collector 50 at the rear of the scraping roll 40.

  (g) Since the presser roll 30 and the scraping roll 40 bite each other and are greatly bent and deformed with respect to the floor surface 1, a triangular shape is formed between the meeting point A of the both rolls 30 and 40 and the floor surface 1. The dead space is substantially eliminated, and both rolls 30 and 40 can be associated with each other on the floor surface 1 with almost no gap. For this reason, the dust on the floor surface 1 pressed by the pressing roll 30 is transferred to the meeting point A with the scraping roll 40 without being left over, and is sandwiched between the rolls 30 and 40 at the meeting point A, The dust pushed out by the press roll 30 at the separation point B between the rolls 30 and 40 can be collected by being scraped off by the roll 40.

  (h) When dust such as a thin paper sheet that passes under the press roll 30 is pushed back by the scraping roll 40 that is rotating in the opposite direction, the pushed-back portion is immediately put into the rolls at the meeting point A of the rolls 30 and 40. It picks between 30 and 40, is pushed out to the press roll 30 by the separation point B of these both rolls 30 and 40, is flipped off by the scraping roll 40, and is collected.

  (i) The pressing roll 30 made of a cylindrical sponge softly deforms so as to follow the entire surface of the uneven surface of the floor surface 1 without gaps, and suppresses dust on the uneven surface, or against large dust on the floor surface. The large debris can be pressed softly so as to wrap it, and the debris can be reliably transferred to the side of the meeting point A with the scraping roll 40.

  (j) The pressing roll 30 made of a cylindrical sponge can be collected by causing dust such as hair to be entangled on the surface and sticking to the adhesive roll 70 in contact therewith. When the presser roll 30 is made of a brush, hair or the like is entangled with the core of the brush, making it difficult to remove.

  (k) The pressing roll 30 made of a cylindrical sponge can support the adhesive roll 70 and reliably rotate it. When the pressing roll 30 is made of a brush, the brush buckles due to the weight of the adhesive roll 70, and the adhesive roll 70 cannot be rotated.

  In the cleaning tool 10, the dust receiving portion 51 of the dust collecting portion 50 rises high along the outer periphery of the scraping roll 40, and the adhesive roll is close to the outer periphery of the pressing roll 30. Since the upper dust stopper 53 that completely blocks the side of 70 is provided and the entire dust receiving space extending from the dust feed port 54 to the rear lid 55 is closed, the pressing roll 30 and the scraping roll 40 are flipped. Good collection of flying garbage.

  Further, the cleaning tool 10 is not limited to the one in which the pressing roll 30 is directly coupled to the rotating shaft 21 </ b> A of the front wheel 21, and may be one in which a speed increasing gear is interposed between the front wheel 21 and the pressing roll 30. Further, the pressing roll 30 is not limited to the one using the rotational force of the front wheel 21 as a drive source, and may be one rotated by another drive source.

The slider-side roll support shaft 134 is fixed to the other side wall of the rotary cover 132 by a screw 139 after inserting the slide plate 136, the coil spring 137, and the spacer 138.

  The adhesive holder 130 maintains the state in which the scraping body 116, the contact rotating body 118, and the adhesive roll 121 are supported by the frame 115, and the contact state between the scraping body 116, the contact rotating body 118, and the adhesive roll 121 is not changed. The isolation means for switching the contact state is configured. Specifically, the adhesive roll holder 130 has left and right rotating support shafts 141 and 142 projecting from the outer surfaces of both side walls of the rotating cover 132 in shaft holes 141A and 142A provided on the left and right side portions of the window frame 131. The rotary cover 132 can be opened / closed and rotated around the rotation support shafts 141 and 142 by fitting. At this time, the rotation support shafts 141 and 142 of the rotation cover 132 are eccentric with respect to the roll support shafts 133 and 134. In a closed state (FIG. 18), which will be described later, the roll support shafts 133 and 134 are brought closer to the scraping body 116 and the contact rotation body 118 than the rotation support shafts 141 and 142 (the rotation support shafts 141 and 142 are scraped). The roll support shafts 133 and 134 make the distance to the scraping body 116 and the contact rotating body 118 smaller than the distance to the lifting body 116 and the contact rotating body 118). Thereby, when the rotation cover 132 rotates, the rotation cover 132 does not interfere with the scraping body 116 and the contact rotation body 118.

  As shown in FIGS. 16 and 18, the rotary cover 132 has a front edge flange 132 </ b> A (having the magnet 150) having a half-arc cross section or a U-shaped cross section of the rotary cover 132 in front of the window frame 131. The window frame 131 is closed and the adhesive roll 121 supported by the two roll support shafts 133 and 134 is covered in a state where it is positioned at the closed position where it abuts against the iron plate 151 at the upper edge of the part, and the scraping body 116 and the contact rotating body 118 and the adhesive roll 121 are brought into contact. On the other hand, as shown in FIGS. 17 and 19, the window frame 131 is opened with the front edge flange 132 </ b> A of the rotation cover 132 positioned at the open position where the front edge flange 132 </ b> A abuts the iron plate 152 at the rear upper edge of the window frame 131. 132 is interposed between the scraping body 116, the contact rotating body 118 and the adhesive roll 121, the adhesive roll 121 is exposed to the outside, and the scraping body 116, the contact rotating body 118 and the adhesive roll 121 are brought into a non-contact state. The core 121B of the old and new adhesive rolls 121 is attached to and detached from the support shafts 133 and 134, or the used adhesive sheet 121A of the adhesive roll 121 set on both roll support shafts 133 and 134 can be peeled and removed. That is, when the rotary cover 132 moves from the closed position to the open position, the rear edge portion of the rotary cover 132 opposite to the front edge flange 132A is passed above the scraping body 116 and the contact rotary body 118, thereby scraping. It is interposed between the raising body 116, the contact rotating body 118 and the adhesive roll 121. As a result, when the rotation cover 132 is opened and the used one turn of the adhesive sheet 121A of the adhesive roll 121 set on the both support shafts 133 and 134 is peeled and removed, the adhesive sheet 121A is removed. It can be smoothly peeled off without sticking to the outer periphery of the scraping body 116 and the contact rotating body 118. The peeled end of the adhesive sheet 121 </ b> A can be cut using the front edge or the rear edge of the rotary cover 132.

  The adhesive roll holder 130 presses the slide plate 136 against the free end flange side of the slide side roll spindle 134 with a coil spring 137 with the adhesive roll 121 set on both roll spindles 133 and 134 as shown in FIG. The distance between the slide plate 136 and the one side wall of the window frame 131 opposed to the slide plate 136 is reduced to prevent the axial displacement of the adhesive roll 121 from the slide-side roll support 134. On the other hand, when the adhesive roll 121 is removed from the roll support shafts 133 and 134, as shown in FIG. 21, the adhesive roll 121 is pushed toward the slide plate 136 (P1), thereby compressing the coil spring 137 and the slide plate 136.
