And the cleaning tool provided with the cleaning material holding head.

Japanese Patent No. 2607207 describes a base formed of a rigid body in a wiping cleaning tool in which a wiping cloth is attached to the bottom surface of a base portion having a handle and the wiping cloth is rubbed against the surface to be cleaned to perform wiping and cleaning. It is erected on substantially the entire surface of the bottom surface of the base portion and the base portion, and elastically deforms and bends when a predetermined pressing force is applied, and elastically deforms and stretches when a predetermined pressing force is released. Disclosed is a wiping cleaner comprising a plurality of elastic protrusions and a wiping cloth attached to the bottom surface of the base portion so as to cover the plurality of elastic protrusions.

According to this wiping tool, it is said to have the following effects.
"A part of the plurality of elastic protrusions erected on the bottom surface of the base portion, depending on the traveling direction of the base portion and the angle of the handle that presses the base portion against the surface to be cleaned with respect to the surface to be cleaned, Since it is pressed by the pressing force from the handle and the reaction force from the surface to be cleaned, it is elastically deformed and bent, so only the wiping cloth part that covers the elastically deformed and bent elastic protrusion part is covered. It comes into contact with the cleaning surface, and the surface to be cleaned can be scratched only by this portion.

That is, the contact area with the surface to be cleaned can be reduced because the wiping cloth scratches the surface to be cleaned by receiving the pressing force from the handle, and the wiping cloth is covered by the elastic force of the elastic protrusion. Since it can be pressed against the cleaning surface, the ground contact pressure of the wiping cloth per unit area can be significantly improved, and dirt stuck to the surface to be cleaned can be easily wiped off without leaving any residue. You will be able to.

Further, when the surface to be cleaned has irregularities, the elastic protrusions that are elastically deformed and bent by being pressed by the surface to be cleaned can be further elastically deformed following these irregularities and can repeat stretching and bending. It is a thing. For this reason, the wiping cloth portion covering the elastically deformed and bent elastic protrusion portion can surely scrape the surface to be cleaned along the unevenness of the surface to be cleaned, and can be compared to the surface to be cleaned. Even if there are irregularities, it becomes possible to perform wiping without leaving the surface to be wiped.

Therefore, according to the wiping cleaning tool of the present invention, the contact patch pressure per unit area of the wiping cloth can be increased, and the wiping cloth can be scraped by following the uneven state of the surface to be cleaned. Therefore, the occurrence of unwiped residue is prevented, and the cleaning ability can be significantly improved. "

However, the wiping cleaning tool described in Japanese Patent No. 2607207 is erected on substantially the entire bottom surface of the base portion, and when a predetermined pressing force is applied, the wiping tool is elastically deformed and bent, and the predetermined pressing force is applied. The plurality of elastic protrusions that elastically deform and stretch when released by elastically pressing the wiping cloth attached to the bottom surface of the base, thereby elastically pressing the outer peripheral edge of the part of the wiping cloth where the elastic protrusions exist. It has been found that the effect of wiping dust is enhanced only in the vicinity of the portion, and there is a problem that the wiping ability of the wiping cloth on the bottom surface of the base portion cannot be fully utilized.

A cleaning material holding head C for wiping and cleaning an object by a wiping portion B1 located on the bottom surface side is provided.

The cleaning material holding head C has a rectangular shape in a plan view, and is mainly composed of a metal substrate D having a rectangular shape in a plan view. The first direction S, which is the main wiping direction of the cleaning material holding head C, is the lateral direction in a plan view, and the second direction T is a direction orthogonal to the first direction S.

A wiping material support E made of synthetic rubber is held on the outer peripheral portion and the lower side of the substrate D.

At the upper center of the substrate D, a handle P for the user to operate the cleaning material holding head C is supported at the base so that the handle P can tilt in any direction and in any angle of inclination. It is provided with a universal support portion D1 that can be used. The universal support portion D1 has a first rotation axis D1a in the horizontal direction and a second rotation axis D1b having a rotation axis perpendicular to the rotation axis of the first rotation axis D1a at a twisted position.

On both sides of the second direction T of the substrate D, the peripheral portions B2 of the opposite sides of the wiping material B, which covers the bottom surface side and is folded back to the upper side of the cleaning material holding head C, are connected to the upper surface of the cleaning material holding head C. A pair of wiping material pressing and holding bodies D2 for pressing and holding are provided back to back in the first direction S.

(2) As shown in FIG. 3, in the substrate D, both side edges of the rectangular flat plate in the first direction S are formed on the flange portion D3 protruding vertically, and the substrate D is located in the central portion of the first direction S. It has an upright plate portion D4 that faces downward and is continuous in two directions T.

(3) The synthetic rubber wiping material support E, which has a rectangular shape in a plan view, is
A flexible base E1 that has a rectangular shape in a plan view and inclines upward from the center to both sides in the first direction S.
An outer side having a cavity having a T-shaped cross section of an inner opening, which is projected upward on both sides of the first direction S of the base E1 and into which flanges D3 on both sides of the first direction S of the base D are fitted. Upper protrusion E2 and
Above the center having a fitting groove with an upper opening, which is projected upward in the central portion of the first direction S of the base E1 and into which the downward upright plate portion D4 in the central portion of the first direction S of the base D is fitted. With the ridge part E3,
The introverted plate portions E4a are provided at the upper ends of the base E1 at both ends of the second direction T, and the lower surface of the introverted plate portion E4a is the upper surface of both ends of the second direction T of the substrate D.

The flexible base E1 in the wiping material support E is held by the base D at both outer upper ridges E2, both end holding portions E4, and the central upper ridge E3, and both ends of the flexible base E1. The portion between the outer upper ridges E2 and the central upper ridge E3 between the portion holding portions E4 has a space between the two outer upper ridges E2 and the central upper ridge E3, and thus can elastically bend upward.

The lower end positions of the both outer pressing ridges E6 are equal, and the lower end position of the central pressing ridge E5 is lower than the lower end position of the both outer pressing ridges E6. Further, the lower end positions of the both outer pressing ridges E6 and the central pressing ridges E5 are above the lower ends of the standing thin sections f and g constituting the standing thin section groups F and G.

Since the central pressing ridge E5 and the both outer pressing ridges E6 are several times thicker than the thickness of the standing thin section f / g, they are several times thicker than the thickness direction of the standing thin section f / g. It is hard to bend.

(4) The standing thin section group G has a symmetrical shape with the standing thin section group F with respect to the central pressing ridge portion E5. The standing flakes group F is as follows.

A large number of standing flakes f constituting the standing flakes group F stand downward from the base E1 on the bottom surface side of the cleaning material holding head C, and each of them can elastically bend in the thickness direction. The upright flakes f have a substantially flat plate shape with both sides flat, and the thickness gradually decreases downward. The thickness direction of the standing flakes f is the first direction S, and the shape in front view (the direction having the largest projected area) is rectangular.

In the standing flakes group F, a large number of standing flakes f arranged at equal intervals along a straight line in the second direction T are arranged in five rows at equal intervals in the first direction S. Hereinafter, the first row F1 to the fifth row F5 will be referred to from the outside of the first direction S toward the inside.

When the cleaning material holding head C is placed on a flat surface, the lower end edges of all the standing thin sections f are in contact with the flat surface. Since the base E1 inclines upward from the central portion toward both sides in the first direction S, the height of the standing flakes f is highest in the first row and gradually decreases toward the fifth row.

In each of the first row F1, the second row F2, the third row F3, and the fifth row F5, the lateral width of the standing thin section f (horizontal width in the front view of the standing thin section f) is constant, and the number of the standing thin sections f. And the position in the second direction T at the center in the horizontal direction is the same in each row.

Assuming that the width of the standing thin pieces f in the first row F1 is 1, the distance between the standing thin pieces f in the first row F1 is about 1.2, and the distance between each row in the first direction S is about 1.5. ..

The width of the standing flakes f in the second row F2 is about 1.45, and the distance between the standing flakes f is about 0.75.

The width of the standing flakes f in the third row F3 and the fifth row F5 is about 1.9, and the distance between the standing flakes f is about 0.3.

In the fourth row F4, except for the positions at both ends, the standing flakes f having a width of about 0.7 are provided at the same positions as the positions in the second direction T at the center of the standing flakes f in the other rows in the width direction, and the width thereof. The standing slice f of 1 is provided so that the position in the second direction T at the center in the width direction is the position in the second direction T at the center in the width direction between the standing slices f in the other rows. The distance between the flakes f is about 0.25, and the width of the standing flakes f at both ends is about 1.25, respectively.

(5) In the standing thin section group F, a part of at least one standing thin section f is located on an arbitrary first direction line. In the first direction line where the standing flakes f of the first row F1 and the fourth row F4 overlap, the standing flakes f from the first row F1 to the fifth row F5 overlap. Further, there is a first direction line in which only the standing flakes f of the fourth row F4 exist, and the first direction line, the third row F3, and the third row in which the standing flakes f of the second, third, and fifth rows overlap. There is also a first direction line on which the standing flakes f of the fourth row F4 and the fifth row F5 overlap.

(6) At regular intervals in the second direction T, from one end of the first direction S toward the other end, in a range not reaching the other end, that is, in the first row F1 in the second direction T. Every time between the standing flakes f, from between the standing flakes f in the first row F1 through between the standing flakes f in the third row F3 to the outer surface of the standing flakes f in the fourth row F4, the standing flakes f Has a recessed portion H in which the is not arranged.

All of these recessed portions H have an isosceles triangle shape (second direction T) in which the width of the second direction T is from between the standing thin sections f of the first row F1 to the outer surface of the standing thin sections f of the fourth row F4. On both sides of the second direction T of the recessed portion H, three standing flakes f from the first row F1 to the third row F3 are arranged at intervals in the first direction S, respectively. ing.

(7) Cover the bottom surface side of the cleaning material holding head C with a square sheet-shaped wiping material B, fold the portion along the opposite side of the cleaning material B to the upper side of the cleaning material holding head C in the first direction S, and fold both sides. It is located on the bottom surface side of the cleaning material holding head C by pressing the portion with the pair of wiping material pressing holding bodies D2 having the portions on both sides of the second direction T to hold the wiping material B on the cleaning material holding head C. Cleaning can be performed by the wiping portion B1.

In that case, by wiping the object while moving the cleaning material holding head C with respect to the object in the first direction S, the standing head C is provided symmetrically with respect to the central pressing ridge portion E5 in the first direction S. The object can be wiped in a state where the standing thin pieces f and g constituting the thin section groups F and G are bent in the first direction S in the thickness direction and the wiping portion B1 is pressed against the object.

Hereinafter, the standing thin section group F will be described on behalf of both standing thin section groups.

Standing flakes group F Each standing flakes f constituting the standing flakes group F can elastically bend in the first direction S, which is the thickness direction, so that the wiping portion B1 can cope well with the unevenness of the object. Can be cleaned while pressing against the object.

In the standing thin section group F, a large number of standing thin sections f are arranged at equal intervals along a straight line in the second direction T, and five rows of standing thin sections are arranged in parallel at equal intervals in the first direction S. A portion of at least one upright slice f is located on any first direction line in the slice group F.

Therefore, by wiping the object while moving the cleaning material holding head C with respect to the object in substantially the first direction S, the wiping portion B1 is made into the object by any of the standing thin pieces f constituting the standing thin section group F. You can wipe the object while pressing it.

Further, every time between the standing flakes f in the first row F1 in the second direction T, between the standing flakes f in the first row F1 and between the standing flakes f in the third row F3, the fourth row F4 It has a recessed portion H in which the standing thin section f is not arranged up to the outer surface of the standing thin section f.

When the object is wiped while the cleaning material holding head C is moved substantially in the first direction S with respect to the object, the moving direction (first direction S) of the wiping portion B1 located on the bottom surface side of the cleaning material holding head C. ) (The front side in FIGS. 1 and 2, the left side in FIG. 3, the upper side in FIG. 4), the portion corresponding to the recessed portion H of the standing slice group F is not pressed by the standing slice f, so that the recessed portion H is not pressed. Dust on the object is captured by the wiping portion B1 from between the standing flakes f in the first row F1 through between the standing flakes f in the third row F3 to the outer surface of the standing flakes f in the fourth row F4. It will be easier. Therefore, the wiping portion B1 located on the bottom surface side of the cleaning material holding head C can be efficiently used as a whole to effectively clean the object.

Further, in all the recessed portions H, the width of the second direction T is reduced in an isosceles triangle shape from between the standing slices f of the first row F1 to the outer surface of the standing slices f of the fourth row F4. Since three (three rows) of standing flakes f are arranged at intervals in the first direction S on both sides of the second direction T of the recessed portion H, both sides of the second direction T are arranged toward the back side. The pressed portion by the standing thin section f gradually reaches inward. Therefore, dust on the object is easily captured by the wiping portion B1.

Further, the bottom surface side of the cleaning material holding head C holding the wiping material B is pressed relatively strongly against the object to sufficiently bend the standing thin section f constituting the standing thin section group F in the thickness direction. The wiping portion B1 can be pressed relatively strongly against the object by the central pressing ridge E5 and the outer pressing ridge E6, which are hard to bend, thereby removing sticky dust and dirt on the object. It can be done effectively.

[2] Embodiments of the present invention will be further described including embodiments other than the above.

(1) The cleaning tool of the present invention holds a wiping material having a sheet-shaped wiping portion so that the wiping portion is located on the bottom side, and wipes the object with the wiping portion located on the bottom side for cleaning. Equipped with a cleaning material holding head for.

The cleaning material holding head is mainly composed of a non-deformable substrate made of synthetic resin, metal, or other materials alone or in combination.

Further, the cleaning material holding head may be connected to an operation handle or may be provided with an operation handle.

The wiping material has a sheet-shaped wiping portion. The entire wiping material may be in the form of a sheet, or a part of the wiping material may be in the form of a sheet. The wiping material does not necessarily have to be in the form of a sheet except for the wiping portion located on the bottom surface side of the cleaning material holding head. The sheet-shaped wiping material or the sheet-shaped portion of the wiping material is made of a non-woven fabric, a woven cloth, another cloth or other sheet-shaped material.

To hold the wiping material on the cleaning material holding head, for example, with the bottom side of the cleaning material holding head covered with the wiping part of the square wiping material, the cleaning materials are placed in the vicinity of the opposite sides of the wiping material. This can be done by folding back to the upper part of the holding head and fixing it detachably by a wiping material fixing portion such as a pressing portion or a holding portion. The holding of the wiping material by the cleaning material holding head is not limited to these, and for example, one part and the other part of the hook-and-loop fastener are provided on the cleaning material holding head and the wiping material, respectively, or one and the other of the snaps are provided. This can be done by detachably fixing the predetermined portion of the wiping material to the cleaning material holding head.

(2) The plan view shape of the cleaning material holding head does not need to be specific. The shape of the cleaning material holding head may be, for example, having a longitudinal direction and a lateral direction in a plan view (in particular, both end edges in the lateral direction or one end edge portion is a straight line in the longitudinal direction. It is preferably in the shape.) The first direction, which is the main wiping direction of the cleaning material holding head, can be set to a direction in which the cleaning efficiency is good depending on, for example, the shape of the cleaning material holding head in a plan view. The first direction, which is the main wiping direction of the cleaning material holding head in the case of having a direction and a lateral direction, is generally the lateral direction. The second direction is a direction orthogonal to the first direction.

(3) There is a group of standing flakes on the bottom side of the cleaning material holding head. The number of standing flakes may be one or two or more. For example, it is possible to have standing flakes on both sides of the intermediate position of the cleaning material holding head in the first direction, and both standing flakes are provided symmetrically with respect to the intermediate position in the first direction, for example. It can, but it is not limited to this.

(4) A large number of standing flakes constituting the standing flakes stand downward on the bottom surface side of the cleaning material holding head, and each of them can elastically bend in the thickness direction. As the constituent material of the standing flakes, for example, a material having rubber-like elasticity such as synthetic rubber can be used.

Each upright slice is preferably, but not necessarily limited to, a substantially flat plate. The wall thickness of each standing slice can be constant, for example, the wall thickness is gradually reduced downward, and the wall thicknesses of the both side edge portions and the lower end edge portions are the end portions, respectively. It can be reduced toward.

The front view (direction with the largest projected area) of each standing slice is, for example, a rectangular or square shape, or an isosceles trapezoidal shape in which the lower base is shorter than the upper base (or vice versa). The lower edge of each upright slice can be horizontal and straight, but is not limited to these.

The standing flakes can be, for example, 3 to 50 mm (preferably 4 to 30 mm, more preferably 5 to 25 mm) in width (horizontal width in front view of the standing flakes) and, for example, 0.3 to 3 mm in thickness. It can be (preferably 0.5 to 2 mm) and, for example, 3 to 50 mm (preferably 4 to 30 mm, more preferably 5 to 25 mm) in height.

(5) When the cleaning material holding head is placed on a flat surface, the lower end edges of all the standing flakes may be in contact with the large number of standing flakes forming the group of standing flakes. , Not necessarily limited to this.

The large number of standing flakes constituting the standing flakes group can all be the same, and for example, a plurality of types of standing flakes having different heights, widths, thicknesses, etc. are arranged regularly or irregularly. Can be considered. When the standing flakes constituting the standing flakes are bent in the thickness direction and the object is wiped while the wiping portion located on the bottom surface side of the cleaning material holding head is pressed against the object, the standing flakes are the height and width. If it consists of multiple types of standing flakes with different thicknesses, the strength and flexibility of pressing the wiping part against the object will differ depending on the height, width, thickness, etc. of the standing flakes. It can correspond to the existence, size, type, etc. of dust on the object.

(6) A large number of standing flakes constituting the standing flakes group have components in the first thickness direction. Desirably, it is an upright flakes whose thickness direction is the first direction. By wiping the object while moving the cleaning material holding head, which holds the wiping material having the sheet-shaped wiping part so that the wiping part is located on the bottom side, in almost the first direction with respect to the object, the standing thin section When wiping an object in a state where the standing flakes forming the group bend in the thickness direction and press the wiping portion against the object, it is preferable that all of them are in the first direction, but the present invention is not limited to this. In addition to the standing flakes constituting the standing flakes, even if the standing flakes having no component in the first direction in the thickness direction is provided on the bottom surface side of the cleaning material holding head, it does not deviate from the present invention. not.

(7) A group of standing flakes consisting of a large number of standing flakes that can stand downward and elastically flex in the thickness direction is, for example, a state in which a large number of standing flakes stand downward from a flexible substrate. It can be obtained as a part of a wiping material support in which the base and a large number of standing flakes are integrally formed of a material having rubber-like elasticity (for example, synthetic rubber).

Each erecting flake in the erecting flake group can be made to be able to elastically flex in the thickness direction substantially independently of each other. Even in a wiping material support in which a large number of standing flakes stand downward from a flexible base and the base and a large number of standing flakes are integrally formed, the flexibility and flexibility of each standing flakes in the thickness direction are possible. By appropriately setting the degree of deformation of the flexible base, when each upright slice bends in the thickness direction, the position and posture of the adjacent upright flakes via the flexible base are substantially adjusted. Can be unaffected. However, even if each of the standing flakes in the standing flakes can be elastically bent in the thickness direction in conjunction with the adjacent standing flakes to some extent, it does not deviate from the scope of the present invention.

(8) The cleaning material holding head can be configured by, for example, holding the base side of the wiping material support under a rigid substrate (a base that can be regarded as rigid in relation to the wiping material support). ..

In this case, the flexible substrate in the wiping material support is held by the substrate in a part thereof (for example, a part of the outer peripheral portion or the outer peripheral portion and the inner portion), and is not held by the substrate. It is possible to have a space between the substrate and the substrate. As a part of the outer peripheral portion and the inner portion, when the cleaning material holding head has a longitudinal direction and a lateral direction in a plan view, for example, a portion along the outer peripheral portion and the center line in the longitudinal direction can be mentioned. When the cleaning material holding head is rectangular in a plan view, for example, a portion along the diagonal line with the outer peripheral portion can be mentioned.

Further, the flexible base in the wiping material support is held by the base in a part thereof, and has a space in which the flexible base can elastically bend between the portion not held by the base and the base. In the case of the cleaning material holding head, the unevenness of the object and dust on the object when the wiping portion is pressed against the object by the standing flakes due to the elastic bending upward of the flexible base. It can be made to correspond to the existence, size, type and the like.

The above-mentioned several sheets or more means, for example, a large number of 5 to 6 sheets or more.

The term "every interval" means, for example, an interval of 1/10 to 5 times, preferably 1/5 to 2 times the width of the standing flakes.

The standing flakes do not need that the center positions of the standing flakes in the lateral width direction are aligned on a predetermined straight line in the first direction.

Further, the standing flakes may be arranged at intervals along a predetermined straight line in the second direction, but they do not necessarily have to be arranged on the predetermined straight line in the second direction.

(10) In the standing flake group, a part of at least one standing flake is located on an arbitrary first direction line, and at intervals in the second direction (for example, at regular intervals or at a fixed rule). (At intervals according to the above), preferably, there are a plurality of recessed portions in which the standing flakes are not arranged, from one end to the other end in the first direction, in a range not reaching the other end. Two or more standing flakes are arranged at intervals in the first direction on both sides of the entrance portion in the second direction.

In the standing flakes group, a portion of at least one standing flakes is located on any first direction line. There is no upright flakes in the recess, but at least one portion of the upright flakes is located on the other end of the recess on any first direction line.

The standing flakes can have one or more recesses (preferably 3-4 or more, more preferably evenly) from one end to the other in the first direction, and further, in the first direction. It may have one or more recesses from the other end to one end.

The second-direction width of all or some recesses in the standing flakes group gradually shrinks from one end (entrance side) in the first direction toward the other end (preferably symmetrical in the second direction [] For example, it is preferable to reduce the size to an isosceles trapezoidal shape or an isosceles triangle shape). The width of all or some of the recesses in the standing flakes in the second direction is not limited to this, and changes from one end (entrance side) in the first direction toward the other end, for example. It can be decided not to change, or it can be reduced on the back side without changing on the entrance side.

The width of the recessed portion in the second direction can be, for example, 3 to 50 mm (preferably 4 to 30 mm, more preferably 5 to 20 mm).

The depth of the recessed portion in the first direction can be, for example, 10 to 100 mm (preferably 10 to 60 mm, more preferably 15 to 40 mm).

(11) On the bottom surface side of the cleaning material holding head, one or two or more pressing ridges made of an elastic material protruding downward are provided, and the lower end position of the pressing ridge is an upright portion constituting a group of standing flakes. It is above the lower end position of the flakes and can be made less likely to bend than the thickness direction of the standing flakes constituting the standing flakes.

Such a pressing ridge portion is made of, for example, the same material as the standing thin section, and the thickness is set to several times to several tens of times or more the thickness of the standing thin section, for example, in the thickness direction of the standing thin section. It can be made several times to several tens of times or more difficult to bend.

The pressing ridge may be located inside the standing flakes and / or outside the standing flakes (preferably near the outside of the standing flakes) on the bottom surface side of the cleaning material holding head.

The direction of the pressing ridge portion is preferably, but is not limited to, the second direction which is orthogonal to the first direction which is the main wiping direction.

As a preferable example of the cleaning material holding head having the pressing ridges on the bottom surface side, the one having the pressing ridges in the second direction at the central portion and both ends in the first direction can be mentioned. can. In this case, the height of the pressing ridges may be, for example, the same height of the pressing ridges at both ends and higher than those of the pressing ridges in the center.

Further, a wiping material support integrally formed with a flexible substrate, a large number of standing flakes, and one or more pressing ridges is held under the rigid substrate to form a cleaning material holding head. be able to.
