[Embodiment 1]
With reference to FIG. 1 and FIG. 2, the cleaning tool 1A which concerns on Embodiment 1 of this invention is demonstrated.
FIG. 1 is a perspective view showing an outline of a cleaning tool 1A according to Embodiment 1 of the present invention.
FIG. 2 is a cross-sectional view of the main part of the cleaning tool 1 </ b> A shown in FIG. 1 when cut along a plane orthogonal to the support shaft 15.

The cleaning tool 1A is disposed in contact with the outer periphery of the roller unit 10 and at least one roller unit 10 that moves while rotating the cleaning surface SS to be cleaned, and accommodates dust (not shown; the same applies hereinafter). The container 30a and the holding | maintenance part 50 which hold | maintains the contact state between the roller part 10 and the storage container 30a are provided.
The roller unit 10 includes a support shaft 15 supported by the holding unit 50, a rotating body 16 that rotates outside the support shaft 15, and a rotary cleaning unit 17 that is coupled to the surface of the rotating body 16 and travels on the cleaning surface SS. Have
The storage container 30 a has an opening 32 that is disposed in the length direction of the support shaft 15 and stores dust, and a friction surface 31 that rubs against the rotary cleaning unit 17 around the opening 32.
The rotary cleaning unit 17 and the friction surface 31 are formed of different insulators that are separated from each other in a charge train that indicates a polarity relationship of charges generated when they are rubbed with each other.

When the roller unit 10 is brought into contact with the cleaning surface SS and the holding unit 50 is moved with respect to the cleaning surface SS, the rotary cleaning unit 17 rotates around the support shaft 15. At this time, since the rotary cleaning unit 17 and the friction surface 31 are in contact with each other, the rotary cleaning unit 17 and the friction surface 31 are rubbed against each other. The rotary cleaning unit 17 and the friction surface 31 are formed of different insulators that occupy distant positions in a charge train that indicates the polarity of charges generated by friction. For this reason, the polarity of the electric charge charged on the rotary cleaning unit 17 and the polarity of the electric charge charged on the friction surface 31 are opposite to each other. That is, when the roller unit 10 is rotated and the rotary cleaning unit 17 and the friction surface 31 are rubbed with each other, the rotary cleaning unit 17 and the friction surface 31 are charged with different polar charges.
In the present embodiment, the rotary cleaning unit 17 is made of, for example, polyester fiber, and the friction surface 31 is made of, for example, a nylon sheet. In this case, the polarity of the charged charge of the rotary cleaning unit 17 is the first polarity (for example, negative polarity), and the polarity of the charged charge of the friction surface 31 is the second polarity (for example, positive polarity) opposite to the first polarity. )

In this charged state, the roller unit 10 (rotary cleaning unit 17) is rotated with respect to the cleaning surface SS and moved in one direction. With the rotational movement of the roller unit 10, the dust on the cleaning surface SS is relatively charged to the second polarity (positive polarity) under the influence of the first polarity (negative polarity) charged by the rotary cleaning unit 17, It is attracted to the rotary cleaning unit 17 by electrostatic attraction acting between the positive charge and the negative charge. The dust adsorbed by the rotary cleaning unit 17 reaches the opening 32 through the friction surface 31 according to the rotation of the rotary cleaning unit 17.
First, the dust (positive polarity) approaching the friction surface 31 is affected by the second polarity (positive polarity) of the friction surface 31 and the charged state relatively changes to the first polarity (negative polarity). In other words, the dust is charged to the first polarity (negative polarity) due to the influence of the charge of the second polarity of the friction surface 31 and has the same polarity as the first polarity (negative polarity) charged by the rotary cleaning unit 17. . The dust that has reached the opening portion 32 is repelled against the electric charge of the rotary cleaning portion 17 by the electrostatic repulsive force that acts between electric charges having the same polarity. Therefore, the dust (negative polarity) adsorbed by the rotary cleaning unit 17 is separated from the rotary cleaning unit 17 (negative polarity) through the opening 32 and is stored in the storage container 30a.

That is, the cleaning tool 1A moves the roller unit 10 while rotating along the cleaning surface SS, and adsorbs dust on the cleaning surface SS to the rotary cleaning unit 17 by the action of the charged charges. The adsorbed dust changes the charging state at the friction surface 31 of the storage container 30a, and is separated from the rotary cleaning part 17 by the action of the charged charge at the opening 32 and stored in the storage container 30a. That is, since the cleaning tool 1A generates a stable charged charge with a simple structure that does not use electric power, the cleaning surface SS can be easily and uniformly cleaned regardless of the state of the cleaning surface SS.
The cleaning tool 1A rubs two kinds of insulators with different positions in the charging row to charge each other, and uses a suction force between charges having different polarities and a repulsive force between charges having the same polarity. Adsorb trash and separate trash. For this reason, since the cleaning tool 1A effectively performs efficient cleaning without using any power, it has extremely high convenience.
The cleaning surface SS is, for example, a floor, a carpet, a tatami mat, a table surface, a shelf, or the like. In addition, the garbage is dust (small garbage such as yarn waste and paper waste), dust (dust, dust, cotton dust), and the like.

Hereinafter, the details of each component will be described.
[About the roller unit 10]
The rotation of the support shaft 15 and the rotation of the rotating body 16 may be either synchronous or asynchronous. When the support shaft 15 and the rotator 16 are integrated (fixed), the support shaft 15 and the rotator 16 rotate synchronously, and the support shaft 15 and the rotator 16 are separated to rotate individually. In this case, the rotating body 16 rotates asynchronously with respect to the support shaft 15. Since charging in the rotary cleaning unit 17 and the friction surface 31 is caused by the rotation of the rotary cleaning unit 17 and friction with the friction surface 31, the rotary cleaning unit 17 rotates the cleaning surface SS in order to generate frictional charging. The support shaft 15 may be either rotated or not rotated. That is, the support shaft 15 may simply support the rotating body 16.
The diameter of the support shaft 15 is, for example, about 5 mm to 10 mm. Further, both ends of the support shaft 15 pass through a through hole (not shown) formed at the tip of the branch portion 50b and are fastened to the branch portion 50b by a fastener 20 having an appropriate shaft stopping structure. The support shaft 15 is made of aluminum, aluminum alloy, polypropylene, or the like. The length of the support shaft 15 is, for example, about 10 to 30 cm. The length of the support shaft 15 is slightly longer than the length of the rotating body 16 because the length that passes through the branch portion 50b and is held by the fastener is required.

The rotating body 16 may be formed of the same member as the support shaft 15 or may be formed of a member different from the support shaft 15. The rotating body 16 is made of, for example, polypropylene (PP) or vinyl chloride. Since polypropylene has high strength and is lightweight, the strength of the roller portion 10 can be secured and the weight can be reduced. The outer diameter of the rotating body 16 is, for example, about 2 cm to 10 cm, and is set according to the size of the cleaning tool 1A. The rotating body 16 shows a broken state as a columnar shape (FIG. 2), but may be a cylindrical shape in which spokes are arranged between an inner diameter and an outer diameter, for example.
The rotary cleaning unit 17 is formed of, for example, a polyester fiber bristle material, and is formed by bonding a large number of bristle materials having a bristle length of, for example, about 5 to 15 mm to the rotary body 16 in a flocked state. That is, the rotary cleaning unit 17 is in a state in which the hair material is arranged in a cotton shape with respect to the rotating body 16. Since the rotary cleaning part 17 is cotton-like, it can be easily and reliably brought into contact with the friction surface 31 by positioning with respect to the opening part 32. The rotary cleaning unit 17 (roller unit 10) has a form similar to, for example, a paint roller applied to paint coating.
The rotary cleaning unit 17 having a cotton shape does not have a fixed outer diameter such as a solid material, but has an outer diameter that comes into contact with the friction surface 31 and is rubbed. The outer diameter of the rotary cleaning unit 17 is defined by the type of hair material, hair length, density, and the like. In the present embodiment, the outer diameter of the rotating body 16 is about 5 cm, and the outer diameter of the rotary cleaning unit 17 is about 7 cm.

[Container 30a]
The container 30a is substantially a rectangular parallelepiped, and a shaft hole (see the holding shaft 38 in FIG. 2) is formed in the holding surface 35 facing the holding portion 50, and the holding shaft 38 disposed in parallel with the support shaft 15 is fixed. It is fixed to the holding part 50 via the tool 21. The storage container 30a is not particularly limited to a rectangular parallelepiped as long as it has a shape that can secure the friction surface 31 including the opening 32. The friction surface 31 may be disposed so as to generate friction with the rotary cleaning unit 17. The friction surface 31 is disposed around the opening 32 so as to be rubbed with the rotary cleaning unit 17. The friction direction is not limited to one direction, but includes the reverse direction. Therefore, the friction surface 31 is disposed on both sides of the opening 32.
Although the case where the holding shaft 38 penetrates the holding surface 35 of the storage container 30a is illustrated as an aspect in which the holding unit 50 holds the storage container 30a (FIG. 2), the embodiment is not limited to the holding shaft 38. That is, it is sufficient that the holding surface 35 is held by the holding unit 50. For example, the holding surface 35 may have a coupling member held by the holding unit 50. Specifically, a configuration may be adopted in which a convex member (or concave member) is combined with the holding surface 35 and a concave member (or convex portion) is combined with the holding portion 50 (branch portion 50b) and fitted together.
The container 30a is made of, for example, a nylon sheet. When the entire container 30a is a nylon sheet, the friction surface 31 is formed of a nylon sheet, so that different charges are easily charged by friction with the rotary cleaning unit 17 formed of polyester fiber.

Since the friction surface 31 that contacts the rotary cleaning unit 17 only needs to be charged, it is not necessary to form the entire container 30a with the same type of insulator as the friction surface 31. For example, the friction surface 31 in which the opening 32 is disposed may be formed of a nylon sheet, and the other surface may be formed of another synthetic resin having an appropriate strength and shape.
When the storage container 30a is formed of a nylon sheet, in order to supplement the strength of the nylon sheet, for example, a framework positioned at each ridge of the rectangular parallelepiped may be incorporated inside. Or the form which affixes a nylon sheet on the surface of a box-type container may be sufficient.

The friction surface 31 comes into contact with the rotary cleaning unit 17 before the dust reaches the opening 32 and changes the charged state. That is, the friction surface 31 is disposed around the opening 32. If the container 30a is a rectangular parallelepiped, the entire surface having the opening 32 is used as the friction surface 31, so that stable friction occurs between the rotary cleaning unit 17 and the friction surface 31. The opening 32 preferably has a rectangular shape having two long sides parallel to the length direction of the support shaft 15 and two short sides in a direction intersecting the support shaft 15. Since the opening 32 is rectangular, dust can be efficiently accommodated.
The container 30a may have a take-out portion (not shown; see the take-out portion 40 in FIG. 3) for taking out dust on a surface different from the friction surface 31. Alternatively, the fastener 21 may be released, the container 30a may be removed from the holding unit 50, and the dust may be discarded from the opening 32.
The friction surface 31 may be curved along the curvature of the rotary cleaning unit 17 to increase the contact area (friction area) with the rotary cleaning unit 17. By increasing the friction area between the rotary cleaning unit 17 and the friction surface 31, it is possible to improve the adsorption action of the rotary cleaning unit 17 against dust by increasing the charge amount of the charged charges. When the container 30a is formed of a nylon sheet, if the distance between the support shaft 15 and the holding shaft 38 is shortened to reduce the distance between the rotary cleaning unit 17 and the friction surface 31, the friction surface 31 is It is deformed along the outer diameter and the contact area between them can be expanded.

[About the holding unit 50]
The holding part 50 is a U-shaped (tuning fork type) having two branch parts 50b arranged symmetrically at both ends of the roller part 10 and a connecting part 53 that connects the two branch parts 50b. The two branch portions 50b hold both ends of the support shaft 15 at their tips, and hold the storage container 30a in contact with the rotary cleaning portion 17. Therefore, the cleaning tool 1A has a tip side (support shaft) of the branch portion 50b. Since the inclination of the holding part 50 with respect to the cleaning surface SS is adjusted starting from 15), the operability is high.
The support shaft 15 penetrating the tips of the two opposite branch portions 50b is fastened to the branch portion 50b by the fastener 20. Further, the container 30a (holding surface 35) is fastened with the fastener 21 in the middle of the branch part 50b. The branch portions 50b are arranged symmetrically on both sides of the roller portion 10 and the storage container 30a in order to position the holding surfaces 35 on both ends of the support shaft 15 and on both sides of the storage container 30a. The branch part 50b is an elongated I-shaped plate, and integrally includes a coupling part 53 constituting a part of the U-shape at the base opposite to the tip.
The branch part 50b positions the support shaft 15 and the container 30a so that the rotary cleaning part 17 and the friction surface 31 come into contact with each other and rub against each other. The holding unit 50 is preferably a lightweight metal such as aluminum or aluminum alloy from the viewpoint of strength, weight reduction, safety, and the like.
Moreover, since the storage container 30a is arrange | positioned on the diagonal upper side away from the cleaning surface SS with respect to the roller part 10, the state which the friction surface 31 is rubbing with respect to the rotary cleaning part 17 can be confirmed easily. Therefore, frictional charging due to friction between the friction surface 31 and the rotary cleaning unit 17 can be generated with high reliability.

  A handle 60 is connected to the outside of the center of the coupling portion 53. The handle 60 is arranged in parallel with the extending direction of the branch part 50b, and the inclination with respect to the cleaning surface SS coincides with the branch part 50b (holding part 50). Therefore, the handle 60 can easily and accurately adjust the position of the opening 32 with respect to the rotary cleaning unit 17 (inclination angle with respect to the cleaning surface SS). The handle 60 is adjusted in operability by changing the inclination with respect to the cleaning surface SS by an operator (not shown). The handle 60 is formed of a member that is easy for an operator to hold. The same material as the holding unit 50 may be used, or a different material may be used.

[Other supplementary items]
The friction surface 31 is shown in a circumscribed state with respect to the rotary cleaning unit 17 in consideration of the visibility of the drawing (FIG. 2). Specifically, the friction surface 31 (around the opening 32) is in contact with the rotary cleaning unit 17. The contact area between the friction surface 31 and the rotary cleaning unit 17 is made larger than shown. For example, when the friction surface 31 has a shape that is curved in advance along the arc of the rotary cleaning unit 17, the friction area between the friction surface 31 and the rotary cleaning unit 17 is further increased, and the charge can be increased.
The curvature of the friction surface 31 is caused by pressing the friction surface 31 against the rotary cleaning unit 17. That is, when the friction surface is formed of a soft material having flexibility, the friction surface 31 pressed against the rotary cleaning unit 17 is curved along the rotary cleaning unit 17. In this case, the friction surface 31 compresses and shrinks the outer diameter of the rotary cleaning unit 17, and the opening 32 and the surrounding friction surface 31 push the rotary cleaning unit 17. It becomes wide and strong, and the amount of charged charges increases.

When the container 30a is formed of a nylon sheet, the friction surface 31 can be easily curved along the rotary cleaning unit 17 by shortening the distance between the support shaft 15 and the holding shaft 38. If the friction surface 31 is curved along the rotary cleaning unit 17, the charged charge due to friction increases, so that the dust adsorption force in the rotary cleaning unit 17 is improved. The friction surface 31 only needs to have an area and a shape from which a charged charge necessary for the cleaning tool 1A can be obtained. That is, the friction surface 31 may be disposed only around the opening 32.
The cleaning tool 1A is made of polyester fiber, nylon sheet, vinyl chloride, acrylic plate, etc., which is resistant to wear and various environments, as a material constituting main members such as the roller unit 10 and the container 30a. Therefore, the cleaning tool 1A has almost no need for maintenance, and does not require an electricity bill and is manufactured at a low cost.

In addition, although the case where the roller part 10 was one was demonstrated, at least one roller part 10 should just be sufficient and the roller part 10 can be made to clean by connecting in parallel or plural in series. By connecting the roller part 10, the cleaning range can be expanded.
In the case of series connection in which a plurality of roller portions 10 are arranged in the extending direction of the support shaft 15, a plurality of coupling portions 53 are arranged along the direction of the support shaft 15, and the plurality of coupling portions 53 are connected to each other. Is done. In the case of parallel connection in which a plurality of roller portions 10 are arranged in a direction intersecting with the support shaft 15, a plurality of coupling portions 53 are arranged along a direction intersecting with the support shaft 15, and the plurality of coupling portions 53 are mutually connected. Realized by connecting.

[Embodiment 2]
With reference to FIG. 3 and FIG. 4, the cleaning tool 1B which concerns on Embodiment 2 of this invention is demonstrated.
FIG. 3 is a side view showing an overview viewed from the axial direction of the support shaft 15 of the cleaning tool 1B according to Embodiment 2 of the present invention.
FIG. 4 is a cross-sectional view of the main part when the main part of the cleaning tool 1 </ b> B shown in FIG. 3 is cut along a plane orthogonal to the support shaft 15.

In the cleaning tool 1B, a pair of roller units 10 according to the first embodiment are arranged on both sides of the storage container 30b. That is, the cleaning tool 1B has two roller parts 10 (first roller part 10f and second roller part 10s), and the container 30b corresponding to the container 30a has two friction surfaces 31 (first The point having the friction surface 31f and the second friction surface 31s) is mainly different from the cleaning tool 1A. Since the basic configuration is the same as that of the first embodiment, items different from the first embodiment will be mainly described.
As with the roller unit 10 (Embodiment 1), the first roller unit 10f has a first support shaft 15f as the support shaft 15 (Embodiment 1) and a first rotation as the rotating body 16 (Embodiment 1). It has the body 16f and the 1st rotation cleaning part 17f as the rotation cleaning part 17 (Embodiment 1). Similarly to the roller unit 10, the second roller unit 10 s includes a second support shaft 15 s as the support shaft 15, a second rotary body 16 s as the rotary body 16, and a second rotary cleaning unit 17 s as the rotary cleaning unit 17. . The first support shaft 15f, the first rotary body 16f, the first rotary cleaning unit 17f, the second support shaft 15s, the second rotary body 16s, and the second rotary cleaning unit 17s have the same configuration and operation as the roller unit 10, respectively. Description is omitted as appropriate.

A storage container 30b corresponding to the storage container 30a has a first friction surface 31f and a second friction surface 31s as the friction surfaces 31 (Embodiment 1). The first friction surface 31 f has a first opening 32 f as the opening 32 (Embodiment 1), and the second friction surface 31 s has a second opening 32 s as the opening 32.
In the cleaning tool 1B according to the present embodiment, two roller portions 10 are arranged in parallel, and one is a first roller portion 10f and the other is a second roller portion 10s. The first roller unit 10 f has a first rotary cleaning unit 17 f as the rotary cleaning unit 17, and the second roller unit 10 s has a second rotary cleaning unit 17 s as the rotary cleaning unit 17.

The holding part 51 holds the first end of the first roller part 10f and the one end of the second roller part 10s and connects them, and the other end of the first roller part 10f. And a second connecting portion 52s that holds the other end of the second roller portion 10s (the opposite side in FIG. 3; it is not shown in the figure because it overlaps the first connecting portion 52f). The first connecting part 52f and the second connecting part 52s hold the storage container 30b between the first roller part 10f and the second roller part 10s.
The container 30b includes a first opening 32f as an opening 32 disposed on the first rotational cleaning part 17f side, and a second opening as an opening 32 disposed on the second rotational cleaning part 17s side. The first friction surface 31f as the friction surface 31 in which the first opening 32f is formed and the second friction surface 31s as the friction surface 31 in which the second opening 32s is formed.

The first roller unit 10 f and the second roller unit 10 s are arranged in parallel and operate as the roller unit 10. Therefore, when the cleaning tool 1B moves, the first roller portion 10f and the second roller portion 10s move in the same direction while rotating in the same manner. Therefore, the first roller unit 10f (first rotary cleaning unit 17f) rubs against the first friction surface 31f, and the second roller unit 10s (second rotary cleaning unit 17s) interacts with the second friction surface 31s. Rubbing. Accordingly, in the first roller unit 10f and the second roller unit 10s, the first rotary cleaning unit 17f and the second rotary cleaning unit 17s are in a charged state, and adsorb dust on the cleaning surface SS.
Further, the dust adsorbed on the first rotary cleaning unit 17f or the second rotary cleaning unit 17s is moved from the first opening 32f in the first rotary cleaning unit 17f by the movement of the first roller unit 10f and the second roller unit 10s. It accommodates in the storage container 30b, and in the 2nd rotation cleaning part 17s, it accommodates in the storage container 30b from the 2nd opening part 32s. That is, when the cleaning tool 1B moves, both the first rotary cleaning unit 17f and the second rotary cleaning unit 17s move on the cleaning surface SS, so that the cleaning area per unit moving distance is doubled to collect garbage. The ability to do this can be improved about twice. Therefore, the cleaning tool 1B improves dust collection efficiency.

Moreover, the two roller parts 10 (the 1st roller part 10f and the 2nd roller part 10s) which were arrange | positioned away will be in the state which follows a cleaning surface SS in parallel. Therefore, the position of the cleaning tool 1B with respect to the cleaning surface SS, and thus the position of the container 30b, is stabilized, and the friction state between the rotary cleaning unit 17 and the friction surface 31 is stabilized, so that the dust collecting ability is improved.
The first roller portion 10 f and the second roller portion 10 s preferably have the same shape (size) as the roller portion 10. In the case of the same shape, the first roller portion 10f and the second roller portion 10s can be easily rotated in synchronization with each other, so that the cleaning surface SS can be smoothly moved regardless of the inclined position of the common connecting portion 54. Further, the operations at the first roller portion 10f and the second roller portion 10s can be made the same.

Hereinafter, the details of each component will be described.
[About the holding unit 51]
The first connecting part 52f and the second connecting part 52s have the same shape and are elongated I-shaped plate-like members. The first connecting portion 52f is connected to the first support shaft 15f and the second support shaft 15s via the fastener 22. The second connecting portion 52s is connected to the first support shaft 15f and the second support shaft 15s via the fastener 23. Accordingly, the first support shaft 15f and the second support shaft 15s, and the first connecting portion 52f and the second connecting portion 52s form a rectangular frame, and therefore the holding portion 51 is configured by the first roller portion 10f and the second connecting portion 52s. The roller part 10s is positioned reliably and arranged in parallel. Further, the first connecting portion 52f and the second connecting portion 52s face each other in parallel and are accurately positioned.
The holding part 51 has a U-shaped common connecting part 54 that connects the first connecting part 52f and the second connecting part 52s. The common coupling portion 54 includes a first branch leg portion 54f and a second branch leg portion 54s that are symmetrically arranged, and a coupling portion 54c that couples the first branch leg portion 54f and the second branch leg portion 54s.

The tip of the first branch leg 54f and the tip of the second branch leg 54s are aligned with both ends of the holding shaft 39 that passes through the container 30b and is connected to the first connecting part 52f and the second connecting part 52s. The fastener 55 is connected by the fastener 55.
The common connecting part 54 is connected to the first connecting part 52f and the second connecting part 52s that are accurately positioned. Moreover, since the common connection part 54 connects with respect to the 1st connection part 52f and the 2nd connection part 52s which are separately arrange | positioned at the both ends of the roller part 10, respectively, the 1st roller part 10f and the 2nd roller part 10s are connected. It becomes possible to connect and operate integrally. In other words, the common connecting portion 54 stably operates the first roller portion 10f and the second roller portion 10s at the same time, and thus stabilizes the dust collection capability.

[Container 30b]
The container 30b includes a first friction surface 31f having a first opening 32f and a second friction surface 31s having a second opening 32s sandwiched between the first roller portion 10f and the second roller portion 10s. The first connecting portion 52f and the second connecting portion 52s are connected to each other through the holding surface 36 facing the first connecting portion 52f and the second connecting portion 52s.
The storage container 30b includes the first connecting portion 52f and the first connecting portion 52f and the second connecting portion 55f (the second connecting portion 52s side) and the fasteners 55 (the first connecting portion 52f side) at both ends of the holding shaft 39 penetrating the holding surface 36. 2 connected to the connecting portion 52s. That is, the holding shaft 39 passes through the holding surface 36 facing the first connecting portion 52f and the second connecting portion 52s, is connected to the first connecting portion 52f by the fastener 55, and is connected to the second connecting portion 52s. Connected with
The storage container 30b is held by a holding shaft 39 that passes through the two holding surfaces 36 respectively facing the first connecting portion 52f and the second connecting portion 52s and is connected to the first connecting portion 52f and the second connecting portion 52s. The

The holding shaft 39 is accurately aligned with the first connecting portion 52f and the second connecting portion 52s. Therefore, the storage container 30b through which the holding shaft 39 penetrates accurately contacts the first rotary cleaning part 17f and the second rotary cleaning part 17s and generates a reliable friction.
In addition, it replaces with the holding shaft 39, the fastener which unites and connects the holding surface 36, the 1st connection part 52f, and the 1st branch leg part 54f, the holding surface 36, the 2nd connection part 52s, and the 2nd branch leg part. You may arrange | position the fastener which connects 54s together. According to this configuration, the holding shaft 39 that traverses the container 30b is omitted. Further, the first branch leg portion 54f and the second branch leg portion 54s can connect the first connecting portion 52f and the second connecting portion 52s and the holding surface 36 with a fastener having a small size.

The container 30b is a rectangular parallelepiped, and includes a first friction surface 31f on which the first opening 32f is disposed and a second friction surface 31s on which the second opening 32s is disposed. The first friction surface 31f and the second friction surface 31s are disposed at positions facing each other.
When the container 30b is formed of, for example, a nylon sheet, the two friction surfaces 31 (first friction surfaces) of the container 30b are shortened by shortening the distance between the first support shaft 15f and the second support shaft 15s. 31f and the second friction surface 31s) can be curved along the rotary cleaning unit 17 (the first rotary cleaning unit 17f and the second rotary cleaning unit 17s).
In addition, the container 30b is molded into a curved shape in advance so that the first friction surface 31f and the second friction surface 31s come into contact with each other along the shapes of the first rotation cleaning portion 17f and the second rotation cleaning portion 17s, respectively. Also good.
In addition, non-contact surfaces (inside the container 30b) that do not require charging other than the first friction surface 31f and the second friction surface 31s are attached to the inside of the container 30b by adhering metal foil. Can be prevented.
The friction surface 31 (first friction surface 31f, second friction surface 31s) on which the opening 32 (first opening 32f, second opening 32s) of the storage container 30b is disposed is the rotary cleaning unit 17 (first rotation). If the shape is curved along the arcs of the cleaning portion 17f and the second rotary cleaning portion 17s), the friction surface 31 area between the opening 32 and the rotary cleaning portion 17 is increased, and the charged charge can be increased. .
When the storage container 30b is formed of, for example, a rectangular parallelepiped box, a predetermined insulator can be attached to the surfaces of the first friction surface 31f and the second friction surface 31s to form a friction surface. In this case, for example, a nylon sheet is attached to the surface of the first friction surface 31f, and polypropylene (fiber / cloth), for example, is attached to the surface of the second friction surface 31s.
The storage container 30b has a take-out portion 40 that takes out the stored dust. In the present embodiment, it is arranged on the top surface side between the first friction surface 31f and the second friction surface 31s. The take-out unit 40 facilitates disposal of the stored garbage.

  A handle 61 is attached to the common connecting portion 54. The handle 61 is coupled to the outside of the coupling portion 54 c of the common coupling portion 54. Since the handle 61 is disposed in parallel with the extending direction of the first branch leg 54f and the second branch leg 54s and acts in the same manner as the handle 60 of the first embodiment, the operability of the cleaning tool 1B is improved.

[Insulator combination]
The first rotary cleaning unit 17f and the second rotary cleaning unit 17s are formed of the same insulator, and the first friction surface 31f and the second friction surface 31s are formed of the same insulator.
Since the 1st rotation cleaning part 17f and the 2nd rotation cleaning part 17s are formed with the same insulator, the number of members is controlled and roller part 10 (the 1st roller part 10f and the 2nd roller part 10s) is easy. Can be formed. Further, since the first friction surface 31f and the second friction surface 31s are formed of the same insulator, the number of members can be suppressed and the storage container 30b can be easily formed.
The first rotary cleaning unit 17f and the second rotary cleaning unit 17s are made of, for example, polyester fiber, and the storage container 30b (the first friction surface 31f and the second friction surface 31s) is made of, for example, a nylon sheet. . According to the combination of these insulators, a negative charge is frictionally charged on the polyester fiber, and a positive charge is frictionally charged on the nylon sheet. Therefore, as in the first embodiment, charge adsorption and repulsion occur, so that dust can be adsorbed and accommodated.

[Embodiment 3: Modification of Embodiment 2]
A cleaning tool 1Bc (not shown) according to Embodiment 3 of the present invention will be described.
Cleaning tool 1Bc relates to another combination in which the combination of insulators in cleaning tool 1B according to Embodiment 2 is changed. Since the structure and the like of the cleaning tool 1Bc are the same as those of the cleaning tool 1B, the reference numerals in FIGS.

In the cleaning tool 1Bc, the first rotary cleaning unit 17f and the second rotary cleaning unit 17s are formed of different insulators, and the first friction surface 31f and the second friction surface 31s are formed of different insulators. Therefore, the polarity of the charged charge generated in the first rotary cleaning unit 17f and the polarity of the charged charge generated in the second rotary cleaning unit 17s can be reversed. That is, the charged charge of dust stored in the storage container 30b from the first opening 32f and the charged charge of dust stored in the storage container 30b from the second opening 32s have opposite polarities.
Therefore, since the charged charges of the dust stored in the storage container 30b are mixed with charges of opposite polarities, the charged charges of the dust in the storage container 30b are offset and neutralized. Accordingly, the cleaning tool can easily prevent the stored garbage from adhering to the storage container 30b, and therefore, it is easy to take out and discard the garbage.

In the cleaning tool 1Bc, the first rotary cleaning unit 17f is made of, for example, polypropylene (fiber), and the second rotary cleaning unit 17s is made of, for example, nylon (fiber). The first friction surface 31f that generates friction with the first rotary cleaning unit 17f is formed of, for example, a nylon sheet, and the second friction surface 31s that generates friction with the second rotary cleaning unit 17s is formed of, for example, polypropylene. . In addition, although nylon and polypropylene were illustrated, if it is an insulator satisfying the conditions relating to the charged column, a combination of other insulators can be used.
In the cleaning tool 1Bc, the insulator (for example, polypropylene) that forms the first rotary cleaning portion 17f is the same as the insulator (for example, polypropylene) that forms the second friction surface 31s, and forms the second rotary cleaning portion 17s. The insulator (for example, nylon) is the same as the insulator (for example, nylon) that forms the first friction surface 31f.
Accordingly, the first rotary cleaning unit 17f, the second rotary cleaning unit 17s, the first friction surface 31f, and the second friction surface 31s are limited to two types of insulators (nylon and polypropylene) as a whole. The Further, the charged charge of dust discharged from the first opening 32f to the storage container 30b and the charged charge of dust discharged from the second opening 32s to the storage container 30b have opposite polarities. In other words, the cleaning tool improves the ease of disposal of dust by minimizing the types of insulators to be applied.

According to the combination of these insulators, in the first roller unit 10f, the first rotary cleaning unit 17f (polypropylene) is negatively charged, the first friction surface 31f is positively charged, and in the second roller unit 10s, The second rotary cleaning portion 17s (nylon) is triboelectrically charged with a positive charge and the second friction surface 31s is triboelectrically charged.
Therefore, in the first roller unit 10f (first rotary cleaning unit 17f), the dust adsorbed on the first rotary cleaning unit 17f due to the negative charge of the first rotary cleaning unit 17f is charged with a positive charge. The dust adsorbed by the first rotary cleaning unit 17f approaches the first friction surface 31f as the first roller unit 10f rotates. Along with the approach to the first friction surface 31f, the positive charge charged with dust becomes a negative charge due to the positive charge of the first friction surface 31f, and the charged state changes. The negative charge charged with dust repels the negative charge of the first rotary cleaning unit 17f. For this reason, the dust which reached | attained the 1st opening part 32f leaves | separated from the 1st rotation cleaning part 17f, and is accommodated in the storage container 30b.

  In the second roller unit 10s (second rotary cleaning unit 17s), dust adsorbed on the second rotary cleaning unit 17s due to the positive charge of the second rotary cleaning unit 17s is charged with a negative charge. The dust adsorbed by the second rotary cleaning unit 17s approaches the second friction surface 31s as the second roller unit 10s rotates. Along with the approach to the second friction surface 31s, the negative charge charged with dust becomes a positive charge under the influence of the negative charge on the second friction surface 31s, and the charged state changes. The positive charge charged with dust repels the positive charge of the second rotary cleaning unit 17s. For this reason, the dust which reached | attained the 2nd opening part 32s leaves | separates from the 2nd rotation cleaning part 17s, and is accommodated in the storage container 30b.

The dust discharged from the first roller portion 10f to the storage container 30b has a negative charge, and the dust discharged from the second roller portion 10s to the storage container 30b has a positive charge. Therefore, the dust from the first roller unit 10f accommodated in the storage container 30b and the dust from the second roller unit 10s cancel each other out, and the charged state is suppressed. That is, the dust stored in the storage container 30b is less likely to be attracted to the storage container 30b because electrostatic attraction and electrostatic repulsion due to charging are suppressed. The cleaning tool 1Bc facilitates the disposal of garbage.
In the present embodiment, the first rotary cleaning portion 17f and the second friction surface 31s have the same insulator, and the second rotary cleaning portion 17s and the first friction surface 31f have the same insulator. Different insulators may be used for the rotary cleaning unit 17f and the second friction surface 31s, and different insulators may be used for the second rotary cleaning unit 17s and the first friction surface 31f. In this case, if the wool in the charge train is in the same position as nylon, the polyester in the same position as polypropylene, or the like is applied, the correlation related to the polarity of the charge can be made similar.
The type of the insulator is not limited to the above example, and an appropriate material can be extracted from the charge train according to the polarity of the charged charge to be set.

[Embodiment 4]
With reference to FIG. 5 and FIG. 6, 1 C of cleaning tools which concern on Embodiment 4 of this invention are demonstrated.
FIG. 5 is a perspective view showing an outline of a cleaning tool according to Embodiment 4 of the present invention.
FIG. 6 is a cross-sectional view of the main part when the main part of the cleaning tool shown in FIG. 5 is cut along a plane orthogonal to the support shaft.

  In the cleaning tool 1C according to the present embodiment, the endless belt 26 is applied instead of the rotary cleaning unit 17 of the first embodiment, the first rotary cleaning unit 17f, and the second rotary cleaning unit 17s of the second embodiment. Yes. Since basic elemental technologies are the same as those in the first to third embodiments, a redundant description will be omitted as appropriate, and different items will be mainly described. For the same part, the reference numerals in the other embodiments are cited.

The cleaning tool 1C includes a first rotating portion 25f that moves along the cleaning surface SS to be cleaned while rotating around the first support shaft 24f, and a second support shaft that is disposed in parallel to the first support shaft 24f. A second rotating portion 25s that moves around the cleaning surface SS while rotating around 24s, and a storage container 30c that is disposed between the first rotating portion 25f and the second rotating portion 25s and stores dust. .
In addition, the cleaning tool 1C is disposed outside the first support shaft 24f, the second support shaft 24s, the holding unit 56 that holds the storage container 30c, and the first rotation unit 25f and the second rotation unit 25s. And an endless belt 26 driven by the rotation of the rotating part 25f and the second rotating part 25s.
The container 30c includes a friction surface 31c that contacts the outside of the endless belt 26 and is rubbed against each other, and an opening 32c that is formed on the friction surface 31c in the width direction of the endless belt 26 and stores dust. Have.

The endless belt 26 and the friction surface 31c are formed of different insulators that are separated from each other in a charge train that indicates the polarity relationship of charges generated when they are rubbed with each other.
When the first rotating portion 25f and the second rotating portion 25s are rotated against the cleaning surface SS via the endless belt 26, the endless belt 26 is driven to rotate. At this time, since the endless belt 26 and the friction surface 31c are in contact with each other, the endless belt 26 and the friction surface 31c are rubbed with each other as the endless belt 26 rotates. The endless belt 26 and the friction surface 31c are formed of different insulators that occupy distant positions in a charge train that indicates the polarity of charges generated by friction. For this reason, the polarity of the charge charged on the endless belt 26 and the polarity of the charge charged on the friction surface 31c are opposite to each other.

In the present embodiment, the endless belt 26 is made of, for example, polyester fiber, and the friction surface 31c is made of, for example, a nylon sheet. In this case, the polarity of the charged charge of the endless belt 26 is the first polarity (for example, negative polarity), and the polarity of the charged charge of the friction surface 31c is the second polarity (for example, positive polarity) opposite to the first polarity. )
In this charged state, when the first rotating portion 25f and the second rotating portion 25s are rotated and moved in one direction with respect to the cleaning surface SS, the first rotating portion 25f and the second rotating portion 25s are rotated and moved. The endless belt 26 rotates. As the endless belt 26 moves, dust on the cleaning surface SS is charged to the second polarity (positive polarity) relatively under the influence of the first polarity (negative polarity) that the endless belt 26 is charged. It is attracted to the endless belt 26 by an electrostatic attraction acting between a positive charge and a negative charge. The dust adsorbed on the endless belt 26 reaches the opening 32c through the friction surface 31c as the endless belt 26 rotates.

  First, the dust (positive polarity) that has reached the friction surface 31c is affected by the second polarity (positive) of the friction surface 31c, and the charged state relatively changes to the first polarity (negative polarity). That is, the dust is charged to the first polarity (negative polarity) due to the influence of the charge of the second polarity of the friction surface 31c, and the endless belt 26 is charged as it moves to the opening 32c. They have the same polarity as the (negative polarity) charge and repel each other due to the electrostatic repulsive force acting between the charges of the same polarity. Accordingly, the dust (negative polarity) adsorbed on the endless belt 26 is separated from the endless belt 26 (negative polarity) through the opening 32c and is stored in the storage container 30c.

The cleaning tool 1C moves the endless belt 26 along the cleaning surface SS while rotating, and adsorbs dust on the cleaning surface SS to the endless belt 26 by the action of the charged electric charge. The adsorbed dust changes the charging state at the friction surface 31c of the storage container 30c, and is separated from the endless belt 26 by the action of the charged charge at the opening 32c and stored in the storage container 30c. That is, the cleaning tool 1C can easily clean the cleaning surface SS with a simple structure that does not use electric power.
The cleaning tool 1 </ b> C rubs two kinds of insulators having different positions in the charging row to charge each other, and uses an attractive force between charges having different polarities and a repulsive force between charges having the same polarity. . For this reason, since the cleaning tool 1C effectively performs efficient cleaning without using any power, it achieves extremely high convenience.

When the first rotating unit 25f and the second rotating unit 25s rotate clockwise in the drawing, the endless belt 26 rotates clockwise following the first rotating unit 25f and the second rotating unit 25s. In this case, the dust adsorbed by the endless belt 26 on the second rotating portion 25s side is accommodated in the accommodating container 30c through the opening 32c. Further, when counterclockwise, the dust adsorbed on the endless belt 26 on the first rotating portion 25f side is accommodated in the accommodating container 30c through the opening 32c.
The endless belt 26 formed of polyester fiber was able to secure sufficient strength with, for example, a hair material woven into a cloth and a thickness of about 0.5 mm, for example.
For the endless belt 26, it is preferable to select a material (cloth) with less expansion / contraction so that the expansion / contraction of the belt length does not affect the rotation of the first rotation unit 25f and the second rotation unit 25s. Moreover, it is preferable that the endless belt 26 has a thickness that is a combined height of the bristle material and the cloth so as to be about 0.5 cm to 1 cm so as not to be affected by the unevenness of the cleaning surface SS.

Hereinafter, the details of each component will be described.
[About the holding unit 56]
The holding portion 56 includes a frame 56f that holds the first support shaft 24f, the second support shaft 24s, and the storage container 30c, and a top plate 56t that covers the top surface of the endless belt 26 and is coupled to the frame 56f. And have. Since the frame 56f and the top plate 56t surround the endless belt 26, the endless belt 26 is protected from the surrounding environment. For this reason, the endless belt 26 can improve reliability. Further, the influence of the charged charge of the endless belt 26 on the surroundings can be suppressed.
The first support shaft 24f and the second support shaft 24s are connected to the frame body 56f by a fastener 58 and a fastener 58, respectively. The frame body 56f and the top plate 56t may be formed of plastic, for example, and may be formed of the same material into an integral box shape.

A top plate connecting portion 57 that can change an angle with respect to the cleaning surface SS is connected to the top plate 56t via a mounting portion 57b. A handle 62 is connected to the top plate connecting portion 57. Since the top plate connecting portion 57 is connected via the rotating member of the mounting portion 57b, the inclination with respect to the cleaning surface SS can be freely changed. Therefore, the top plate connecting portion can be adjusted by adjusting the inclination of the handle 62 with respect to the cleaning surface SS. The inclination 57 can be easily operated. Even if the inclination of the handle 62 is changed, the first rotating unit 25f and the second rotating unit 25s stably maintain the state along the cleaning surface SS.
The frame body 56f holds the storage container 30c via the holding shaft 42 penetrating the holding surface 41. The holding shaft 42 is connected to the frame body 56 f through the fastener 59. The top plate connecting portion 57 may be connected to the holding shaft 42 not on the top plate 56t but on the frame 56f. Further, the top plate connecting portion 57 may be directly connected to the frame body 56f except for the attaching portion 57b.

[Container 30c]
The storage container 30c is a rectangular parallelepiped with each edge chamfered. The container 30c has a length in a direction parallel to the first support shaft 24f and the second support shaft 24s, and a cut end surface at a surface intersecting the first support shaft 24f and the second support shaft 24s is substantially rectangular. It is. Since the container 30c is a rectangular parallelepiped, the friction surface 31c disposed on the top surface secures a wide area and reliably generates friction between the friction surface 31c and the endless belt 26. Accordingly, the charged charges on the friction surface 31c and the endless belt 26 can be increased.
Since the container 30c is a rectangular parallelepiped, it can maintain a stable position against the pressure applied to the friction surface 31c as the endless belt 26 rotates. Since the opening part 32c is arrange | positioned at the top | upper surface, it accommodates dust stably. The friction surface 31c is a rectangular parallelepiped top surface, but may be a curved surface having an appropriate curvature.

The storage container 30c has a holding surface 41 on the side facing the frame body 56f. The holding surface 41 does not contribute to the generation of charged charges. The holding surface 41 needs to have a certain strength because it needs to be held by the frame 56f. For example, when the holding surface 41 is formed of a plate member, it is easy to ensure the strength.
The storage container 30c is configured to be held by the frame 56f with the holding shaft 42, but without using the holding shaft 42, an appropriate fastener (not shown) between the holding surface 41 and the frame 56f. It may be connected with.
The storage container 30c is not limited to a rectangular parallelepiped, and may be a cylindrical shape. In the cylindrical storage container 30c, the degree of friction between the endless belt 26 and the storage container 30c (friction surface 31c) is easily suppressed. Since the cylindrical container 30c widens the friction surface 31c product between the friction surface 31c and the endless belt 26, the charged charges on the friction surface 31c and the endless belt 26 can be increased. The cylindrical container 30c suppresses friction by suppressing the friction force between the endless belt 26 and the friction surface 31c, thereby improving the reliability (life) of the cleaning tool 1C.

[Embodiment 5: Modification of Embodiment 4]
A cleaning tool 1D according to Embodiment 5 of the present invention will be described with reference to FIG.
FIG. 7 is a main part plan view showing a planar state of the endless belt 27 of the cleaning tool 1D according to Embodiment 5 of the present invention as viewed from the top surface side.
The cleaning tool 1D has an endless belt 27 obtained by deforming the endless belt 26 of the cleaning tool 1C of the fourth embodiment, and the other configuration is the same as that of the cleaning tool 1C. Therefore, the endless belt 27 will be mainly described. For the same parts, the reference numerals used in the fourth embodiment are cited.

In the cleaning tool 1D, the endless belt 27 is formed of a plurality of parallel belts 27a, parallel belts 27b, and parallel belts 27c arranged in parallel in the width direction (hereinafter, when each of the parallel belts is simply shown, (It may be a parallel belt 27d (not shown)). The insulator forming at least one parallel belt 27d (for example, the parallel belt 27a) is located on the positive side in the charging train with respect to the insulator forming the friction surface 31c, and at least one other parallel belt 27d. The insulator forming the parallel belt 27b (for example, the parallel belt 27b) is each parallel belt 27d (parallel belt 27a, parallel belt 27b, or parallel belt) positioned on the negative polarity side in the charging train with respect to the insulator forming the friction surface 31c 27c) is a material (insulator) having different charging polarities for the insulator forming the container 30c and the insulator located on the positive polarity side and the insulator located on the negative polarity side in the charging column. Formed with.

The cleaning tool 1D is configured so that each of the parallel belts 27d (the parallel belt 27a, the parallel belt 27b, and the parallel belt 27c) has different polarities from each other. Since the types of dust adsorbed by each of the parallel belts 27c) are made different, the cleaning ability is improved.
For example, when the container 30c is formed of acrylic (acrylic plate), the parallel belt 27a and the parallel belt 27c are formed of nylon, and the parallel belt 27b is formed of polyester, the parallel belt 27a and the parallel belt 27c are The parallel belt 27b is charged to a negative polarity with respect to the acrylic plate. Therefore, each parallel belt 27d adsorbs dust having different properties.
In addition, when the parallel belt 27d is arranged in an odd number of three or more, the parallel belt 27d (for example, the parallel belt 2a and the parallel belt 27c) disposed on both sides with respect to the central parallel belt 27d (for example, the parallel belt 27b). If the characteristics of) are made symmetrical, the polar arrangement can be stabilized.
