Description

The present invention relates to a cleaning tool, particularly a cleaning tool having a cleaning tool main body and a handle portion, and wiping a cleaning target with a cleaning sheet attached to the cleaning tool main body.

The cleaning tool body, which covers the cleaning surface and is equipped with a cleaning sheet made of non-woven material, etc., removes dust and dirt from the floor surface, etc. to be cleaned. By wiping the object to be cleaned, dust and dirt can be attached to the cleaning sheet to easily perform cleaning (see, for example, Patent Document 1 and Patent Document 2).

The cleaning tools of Patent Document 1 and Patent Document 2 have a curved shape of the cleaning surface of the lower surface of the cleaning tool main body using an elastic cushioning material so that dust and dirt can be easily taken in from the peripheral portion of the cleaning surface to the inside of the cleaning surface. A large number of irregularities and corrugated ridges are provided to facilitate cleaning of an uneven cleaning target and to easily scrape off dirt on the cleaning target. Further, in the cleaning tools of Patent Document 1 and Patent Document 2, the cleaning tool main body has a horizontally long rectangular flat shape in a plan view, and the short side direction of the rectangular flat shape is the main cleaning direction. Therefore, it is possible to efficiently perform the cleaning work by the cleaning surface having a wide width in the long side direction.

On the other hand, the cleaning tools of Patent Document 1 and Patent Document 2 have a rectangular flat shape with the short side direction as the main cleaning direction, and the cleaning surface having a wide width in the long side direction, such as a floor surface of a living room. It is possible to efficiently clean the floor surface of a wide area, but for example, the floor surface of a narrow area with an installation object, such as a toilet with a toilet bowl, should be cleaned. Not suitable for cleaning work. Therefore, for example, it is required to newly develop a cleaning tool suitable for cleaning an object to be cleaned such as a floor surface or an installation object in a narrow area such as a floor surface or an area with an installation object.

Further, for example, in the case of a cleaning tool whose main body has a rectangular flat shape, the cleaning work can be performed with a narrow width in the short side direction with the long side direction as the cleaning direction, so that the floor surface in a narrow area can be cleaned. It is thought that cleaning will be easier, but with conventional cleaning tools, if the long side direction is the cleaning direction, the cleaning work will be performed by the cleaning surface with a narrow width in the short side direction. When a moment force in the width direction centering on the joint part is applied during work, the width of the cleaning surface is narrowed, and the length protruding from the joint part in the width direction is shortened, so that the cleaning surface is cleaned. The reaction force of the force that presses the object to be cleaned with is not enough to support the applied moment force, and the cleaning tool body wobbles or tilts and falls during work, which improves the stability of operation. It becomes easy to lose.

In the present embodiment, the rotary connecting member 41 provided between the head-side yoke portion 19 and the handle-side yoke portion 24 is, for example, a molded product made of plastic, and FIGS. Further, as shown in FIG. 8, a first rotation axis center portion 41a and a second rotation axis center portion 41b whose central axes C1 and C2 are orthogonal to each other in a grade separation shape are provided. The first rotation shaft center portion 41a of the rotation connecting member 41 has a cylindrical shape, and is provided with engaging projections 41c so as to project from the end faces on both sides. The engaging protrusion 41c has a cylindrical shape arranged concentrically with the first rotation shaft center portion 41a, and the central axis thereof is the central axis C1 of the first rotation shaft center portion 41a. ing.

The engaging projection 41c is a pair when the first rotation shaft center portion 41a of the rotary connecting member 41 is forcibly pushed and attached to the space between the pair of yoke protrusions 19a of the head side yoke portion 19. It is rotatably engaged with an engaging hole 19c formed in each of the upright surfaces 19b of the yoke protrusion 19a. As a result, the outer peripheral surface of the first rotation shaft center portion 41a is in close contact with the sliding friction surface portion 19e provided on the bottom surface portion between the pair of yoke protrusions 19a. Further, a slide taper surface 41d formed by diagonally notching is provided in the lower half portion of each engaging protrusion 41c on the side opposite to the side on which the second rotation shaft center portion 41b protrudes. .. While superimposing these slide tapered surfaces 41d on the guide tapered surface 19d formed on the standing surface 19b of the yoke protrusion 19a, for example, the rotary connecting member 41 attached to the lower end of the handle portion 20 is attached to the head side yoke portion 19 By pushing the rotary connecting member 41 into the space between the pair of yoke protrusions 19a, the operation of forcibly pushing the rotary connecting member 41 to engage the first rotary shaft center 41a with the engagement hole 19c can be performed more smoothly. It becomes possible to do.

The second rotation shaft core portion 41b of the rotation connecting member 41 is, for example, a thick plate-shaped portion having a semi-elliptical front shape provided so as to project outward from the outer peripheral surface of the first rotation shaft core portion 41a. It has become. In the center of the second rotation shaft core portion 41b, a circular shaft for inserting the pin body 25a of the rotation pin member 25 so as to match with the insertion fixing hole 24c formed in the yoke piece 24a of the handle side yoke portion 24. An opening 41e is formed. The opening side sliding sleeve 41f is attached so as to cover the inner peripheral surface of the circular shaft opening 41e. The opening-side sliding sleeve 41f comes into close contact with the outer peripheral surface of the pin-side sliding sleeve 25c mounted on the pin body 25a of the inserted rotary pin member 25, thereby increasing the frictional force with the rotary pin member 25. You can do it. The central axis of the circular shaft opening 41e and the rotating pin member 25 inserted therein is the central axis C2 of the second rotating shaft center portion 41b.

In the present embodiment, for example, in the rotary connecting member 41, the rotary pin member 25 is inserted into the handle side yoke portion 24 in a state where the second rotation shaft center portion 41b is inserted into the through groove 24b between the pair of yoke pieces 24a. It is rotatably attached via. After that, the rotary connecting member 41 attached to the handle side yoke portion 24 at the lower end portion of the handle portion 20 is cut off from the slide tapered surface 41d of the engagement protrusion 41c of the first rotation shaft center portion 41a to the yoke protrusion 19a. While overlapping the guide tapered surface 19d of the surface 19b, the engagement protrusion 41c is rotatably engaged in the engagement hole 19c by forcibly pushing it into the space between the pair of yoke protrusions 19a of the head side yoke portion 19. By combining them, the joint portion 40 is formed. As a result, the lower end portion of the handle portion 20 is provided on the bottom surface portion between the pair of yoke protrusions 19a of the cleaning head 12 for cleaning the outer peripheral surface of the first rotation shaft center portion 41a of the rotary connecting member 41. In a state of being in close contact with 19e, it is rotatably connected to the central portion of the upper surface of the cleaning head 12. As a result, the handle portion 20 is rotated in the left-right direction (X direction) and the front-back direction (Y direction) from the state in which the handle portion 20 is erected vertically with respect to the cleaning head 12 of the cleaning tool main body 11 to tilt it. At the same time, the handle portion 20 can be freely rotated in the circumferential direction around the rotation connecting member 41 as the rotation center.

Further, in the present embodiment, the joint portion 40 between the cleaning head 12 and the handle portion 20 formed in this manner is formed on the outer peripheral surface of the first rotation axis portion 41a and the yoke protrusion 19a of the cleaning head 12. The circular shaft opening 41e of the second rotation shaft center 41b is more than the sliding resistance when rotating around the first rotation shaft center 41a due to the close contact of the bottom surface portion between them with the sliding friction surface portion 19e. The opening-side sliding sleeve 41f that covers the inner peripheral surface and the pin-side sliding sleeve 25c attached to the pin body 25a of the rotating pin member 25 are brought into close contact with each other to rotate around the second rotation axis center 41b. The sliding resistance at that time is larger. As a result, the resistance force against the moment force that tries to rotate in the left-right direction (short side direction) X around the second rotation axis center portion 41b is increased, and the cleaning tool main body 11 wobbles in the left-right direction X during work. It is possible to improve the stability of operation by avoiding tilting or tilting. From this point of view, the sliding resistance when rotating around the second rotation shaft center 41b is 1. It is preferably 2 times or more, more preferably 1.5 times or more, and preferably 10 times or less.

Here, the sliding resistance when rotating in the left-right direction (short side direction) X around the second rotation axis center portion 41b is determined from the state in which the handle portion 20 is vertically erected with respect to the cleaning head 12. This is the peak load measured by the pull push gauge when the handle portion 20 is pushed at a position 50 mm above the central axis C2 of the second rotation shaft center portion 41b until it is tilted by about 45 °. The sliding resistance when rotating in the left-right direction (short side direction) X around the second rotation axis center portion 41b is preferably 0.8 to 2.0 N. The sliding resistance when rotating in the front-rear direction (long side direction) Y about the first rotation axis center portion 41a is such that the handle portion 20 is placed perpendicular to the cleaning head 12 and then the handle portion 20 is set. This is the peak load measured by the pull push gauge when the position 50 mm above the central axis C1 of the first rotation axis center 41a is pushed until it is tilted by about 45 °. The sliding resistance when rotating around the first rotation shaft center portion 41a is preferably 0.2 to 1.2N.

The sliding resistance when rotating around the second rotation shaft core portion 41b and the sliding resistance when rotating around the first rotation shaft core portion 41a are, for example, the opening side sliding sleeve 41f and the like. By adjusting the material and thickness (including diameter) of the pin-side sliding sleeve 25c, and adjusting the material and contact area of the outer peripheral surface of the first rotation shaft center portion 41a and the sliding friction surface portion 19e, It can be easily set.

It will be sandwiched between the lower end surface and the lower end surface so as to be pulled in. Further, this makes it possible to effectively prevent the end portion of the cleaning sheet 30 from being displaced between the upper surface of the end portion of the sandwiched base body 13 and the lower surface of the sandwiched lid piece 54. The cleaning sheet 30 can be attached to the cleaning tool main body 11 in a more stable state.

In the present embodiment, the magnet 52 and the magnetic body 53 are arranged on the back surface side of the insertion recess 51 of the cleaning head 12 and on the back surface side of the cover cap 54d locked to the insertion convex portion 54c of the sandwiching lid piece 54. It is attached to the back surface side of these plate materials in a state of being covered with the plate material forming the upper surface of the cleaning head 12 or the plate material forming the lower surface of the sandwiching lid piece 54. Therefore, it is possible to effectively prevent the magnet 52 and the magnetic body 53 from falling off from the cleaning head 12 during the operation of opening and closing the sandwiching lid piece 54 and attaching / detaching the cleaning sheet 30, and in particular, When the cleaning sheet 30 contains cleaning chemicals and the like, it is possible to effectively prevent the magnet 52 and the magnetic body 53 from deteriorating due to contact with these chemicals and the like.

As shown in FIG. 6A, the cleaning sheet 30 attached to the cleaning tool main body 11 as described above preferably has the cleaning head 12 and the long side portions 12b, 13b of the base body 13 having side portions in the lateral width direction. It is detachably attached to the cleaning tool main body 11 in a state of protruding outward from the outside, and is used for cleaning work. The cleaning sheet 30 used for cleaning work, for example, to which dust and dirt are sufficiently adhered, is in a state in which the sandwiching lid piece 54 is rotated and opened against magnetic force against the magnetic force, and the end portion is sandwiched, for example. By releasing the above, it is possible to remove the cleaning tool main body 11 without touching it, and to dispose of it as it is, for example, by flushing it into a flush toilet.

Further, in the cleaning tool 10 of the present embodiment having the above-described configuration, the cleaning work can be easily performed with the long side direction (Y direction) as the main cleaning direction. It is possible to efficiently perform the work of cleaning the object to be cleaned such as the floor surface and the installation object in a certain area, and it is possible to improve the stability of the operation.

That is, according to the present embodiment, the cleaning tool 10 preferably has a compact shape as compared with the conventional cleaning tool suitable for the work of mainly cleaning the floor surface of the living room and the like, and the cleaning unit main body 11 The cleaning head 12 and the base body 13 have a planar shape having a pair of short side portions 12a and 13a and a pair of long side portions 12b and 13b on both sides of the pair of short side portions 12a and 13a in a plan view. The cleaning head 12 and the handle portion 20 are connected to each other via a joint portion 40, and the joint portion 40 includes a head-side yoke portion 19 provided so as to project from the upper surface of the cleaning head 12 and a handle portion. The handle-side yoke portion 24 provided at the tip portion of 20 is the first rotation axis center portion 41a in which the central axis C1 is arranged in the short side direction (X direction) and the central axis is orthogonal to the central axis, and the long side direction. By connecting the handle portion 20 with respect to the cleaning head 12 in the front-rear direction Y and the left-right direction by connecting via a connecting member 41 provided with the second rotation axis center portion 41b in which the central axis C2 is arranged in the (Y direction). It is designed to be rotatably connected to X. The sliding resistance when the joint portion 40 rotates about the first rotation shaft core portion 41a is larger than the sliding resistance when the joint portion 40 rotates about the second rotation shaft core portion 41b. It has become.

As a result, the cleaning worker prefers to set the long side direction Y as the main cleaning direction, preferably applying a pressing force from the handle portion 20 to the cleaning surface 14 by the lower surface of the base body 13 protruding in a curved shape. Since the cleaning surface can be easily deformed, for example, the cleaning surface 14 which is preferably curved can be satisfactorily elastically deformed while the cleaning unit main body 11 is reciprocated in the long side direction Y. Therefore, the cleaning sheet 30 can be used. While it is easy to take in dust and dirt from the peripheral portion on the covered cleaning surface 14, dust and dirt can be efficiently adhered to the entire cleaning sheet 30 to clean the cleaning target. Further, by setting the long side direction as the main cleaning direction, when the cleaning unit main body 11 is moved in the long side direction, the width of the cleaning unit main body 11 is narrowed by the short side portion 12a, so that the cleaning unit main body 11 should have a compact shape. Together with this, it becomes possible to efficiently perform the work of cleaning the cleaning target such as the floor surface of a narrow area or the floor surface of an area with an installation object.

Further, according to the present embodiment, the joint portion 40 rotates about the second rotation shaft core portion 41b rather than the sliding resistance when the joint portion 40 rotates about the first rotation shaft core portion 41a. Since the sliding resistance at that time is larger, the resistance force against the moment force that tries to rotate in the left-right direction (horizontal width direction) X around the first rotation axis center 41a is increased during work. It is possible to prevent the cleaning tool main body 11 from wobbling or tilting in the left-right direction X, and to improve the stability of operation.

Further, in the present embodiment, the height h1 from the lower surface of the cleaning head 12 to the central axis C1 of the first rotation axis center portion 41a on the side close to the lower surface of the rotary connecting member 41 is, for example, the conventional short side direction. Since it is lower than that of the cleaning tool whose main cleaning direction is X, preferably 10 to 20 mm, it is first compared with, for example, the conventional cleaning tool whose main cleaning direction is the short side direction X. It is possible to further improve the stability of operation by keeping the moment force that tends to rotate in the left-right direction (horizontal width direction) X generated around the rotation axis center portion 41a small.

Furthermore, according to the present embodiment, preferably, the pair of long side portions 12b of the cleaning head 12 includes a constricted portion 12c that is concavely curved toward the center side to which the handle portion 20 is attached. As shown in 6 (b), while making the concavely curved constricted portion 12c follow the side surface of the installation object such as the toilet bowl 60, the cleaning portion main body 11 is smoothly rotated in a small turn, for example, the handle portion 20 is moved. By swirling and wiping without changing hands and making it easier to insert the cleaning unit main body 11 into the floor surface of the space behind the toilet bowl 60, etc., it is more efficient and more efficient, the floor surface of a narrow area or the floor surface of an area with an installation object. Etc. can be cleaned. From the same viewpoint, it is preferable that the base body 13 is also provided with the edge portion 13e at the edge of the annular overhang piece 15 of the portion protruding outward from the long side portion 13b (see FIG. 5). ).

Further, according to the present embodiment, preferably, the base body 13 has a plane shape slightly larger than that of the cleaning head 12, and the peripheral portion of the base body 13 is a flexible and deformable annular overhang piece 15. As a result, since the cleaning head 12 is continuously projected to the outside of the peripheral edge in the circumferential direction, the peripheral edge portion of the base body 13 is placed on the peripheral surface of the surrounding wall or the installation object while flexibly deforming the annular overhanging piece 15. It is possible to easily bring them into close contact with each other and thoroughly clean the corners where dust and paper dust are likely to collect, such as recesses and gaps at the boundary between the peripheral surface of these surrounding walls and installation objects and the floor surface. It will be possible.

Further, in the present embodiment, preferably, the cleaning sheet 30 can be attached to and detached from the cleaning tool main body 11 in a state where the side portion in the lateral width direction protrudes outward from the long side portions 12b and 13b of the cleaning head 12 and the base body 13. Since it is attached to the wall and used for cleaning work, the boundary between the peripheral surface of the surrounding wall or installation and the floor surface is due to the portion protruding outside from these long side portions 12b and 13b. It is possible to more efficiently and firmly clean corners where dust and paper dust are likely to collect, such as recesses and gaps in the parts.

Further, in the present embodiment, the end portion of the cleaning sheet 30 folded back at the short side portion 13a of the base body 13 is sandwiched between the lid pieces 54 to open and close, preferably by the magnetic force of the magnet 52 and the magnetic body 53. By sandwiching and engaging the body 13 between the end portion in the long side direction and the sandwiching lid piece 54, the cleaning sheet 30 can be easily attached to and detachably attached to the cleaning tool main body 11 by covering the cleaning surface 14. Will be possible. The cleaning sheet 30 to which dust and dirt are sufficiently adhered is opened by rotating the sandwiching lid piece 54 against the magnetic force, for example, and the state in which the end portion is sandwiched is released, which is easily and preferably preferable. Can be removed from the cleaning tool main body 11 without touching it, and when, for example, the cleaning sheet 30 is a water-decomposable sheet, it can be directly poured into a flush toilet bowl 60 and discarded.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the end portion of the cleaning sheet is sandwiched between a sandwiching lid and an engaging portion composed of a magnet and a magnetic material, and does not necessarily have to be engaged with the upper surface of the cleaning head, and is formed on the upper surface of the cleaning head. It may be attached by inserting it into the slit of the attached clerk. The base body does not necessarily have to be formed into a thin plate whose cross section along the longitudinal direction is curved in an arc shape, and may be formed so as to have a flat shape.
