Definitions

  • the present invention relates to a cleaning tool comprising a cleaning component and a handle component, and to a method for manufacturing a cleaning component for said cleaning tool.
  • Dusters have been used in the past as cleaning tools for removing dust that builds up on chests and other such furniture; computers, lighting devices, and other such electrical products; and interior walls, thresholds and sills, and so forth.
  • a duster is constructed such that a plurality of cord-like bands are attached to the distal end of a handle component, and the surface of a dusty object is hit with the cord-like bands to remove the dust. Therefore, a conventional duster had no wiping function, so it was unable to remove dust without scattering it into the air.
  • Proposals that have been made in order to help solve this drawback to dusters include a cleaning tool in which a cleaning cloth equipped with a wiping component and a dusting component is attached to the head at the distal end of a handle component ( Japanese Laid-Open Patent Application H10-43115 ), and a hand wiper comprising a handle component, a head component, and a cleaning cloth, with the main portion formed in the center of the head component, and a thin flexible portion formed around the main portion ( Japanese Laid-Open Patent Application 2000-83883 ).
  • the present invention was conceived in order to solve the above problems, and it is an object thereof to provide a cleaning tool that exhibits adequate cleaning performance even in the cleaning of narrow crevices.
  • the present invention provides a cleaning tool comprising a cleaning component and a handle component, wherein the cleaning component is designed such that a sheet-like fiber bundle and a sheet are joined to produce a sheet laminate having a joining portion, this sheet laminate is bent along the joining portion to form a bulky component formation portion, the sheet laminate in which said bulky component formation portion has been formed is bent so that bulky component formation portions are across from each other, and integrated such that the contact surfaces of the opposing sheet-like fiber bundles are joined together, and support rods of the handle component are inserted into a handle insertion component having handle insertion openings made at one end of the bulky component formation portions and formed inside the bulky component formation portion.
  • the cleaning tool of the present invention is constituted such that the sheet laminate is bent and the contact surfaces of the opposing sheet-like fiber bundles are partially joined together to form a bulky component formation portion, and the sheet laminate in which said bulky component formation portion has been formed is bent and the contact surfaces of the opposing sheet-like fiber bundles are joined, forming in a bulky form the bulky portion handle insertion openings made at one end and the handle insertion component in the bulky component formation portion. Accordingly, this cleaning tool can be made in a slender shape, which means that dust and dirt in narrow crevices can be efficiently wiped clean.
  • the handle insertion component is formed by bending the sheet laminate, so there is no need to separately produce and install any parts that would serve as the handle insertion component, which means that fewer parts make up the cleaning tool.
  • the present invention provides a cleaning tool comprising a cleaning component and a handle component, wherein the cleaning component is designed such that a sheet-like fiber bundle and a sheet having a strip component are partially joined to produce a sheet laminate having a joining portion, this sheet laminate is bent along the joining portion to form a bulky component formation portion, the sheet laminate in which said bulky component formation portion has been formed is bent so that bulky component formation portions are across from each other, with the sheet-like fiber bundle on the inside, and integrated such that the contact surfaces of the sheet-like fiber bundles are joined together, and support rods of the handle component are inserted into a handle insertion component having handle insertion openings made at one end of the bulky component formation portions and formed inside the bulky component formation portion.
  • this cleaning tool in addition to the above-mentioned effects of being formed in a slender shape and being able to efficiently remove dust and dirt from narrow crevices, and of reducing the number of parts required, larger dust particles that cannot be wiped away with just the fibers that make up the sheet-like fiber bundle can be wiped away with the strip component provided to the sheet, resulting in even better cleaning performance.
  • the sheet-like fiber bundle may be formed by layering a plurality of sheet-like fiber bundles.
  • the sheet-like fiber bundle may comprise a first sheet-like fiber bundle composed of numerous fibers and a second sheet-like fiber bundle composed of fibers thicker than the fibers that make up the first sheet-like fiber bundle.
  • the sheet-like fiber bundle comprises a first sheet-like fiber bundle and a second sheet-like fiber bundle composed of fibers thicker than the fibers that make up the first sheet-like fiber bundle, and the stiffness of the first sheet-like fiber bundle can be made different from that of the second sheet-like fiber bundle. Specifically, if the fibers that make up a sheet-like fiber bundle are thicker, the stiffness will be higher, so the second sheet-like fiber bundle can be made stiffer. Also, the thinner are the fibers that make up the sheet-like fiber bundle, the more slender will be the fiber bundle when the fibers are made into a sheet-like fiber bundle. Because of this, with this cleaning tool, dust can be efficiently wiped away with the stiffer second sheet-like fiber bundle, while this dust that has been wiped off can be efficiently picked up by the finer first sheet-like fiber bundle, which means that more efficient cleaning is possible.
  • the sheet-like fiber bundle may be constituted such that a first sheet-like fiber bundle composed of numerous fibers and a second sheet-like fiber bundle composed of fibers that are thicker and shorter than the fibers that make up the first sheet-like fiber bundle are partially joined.
  • the fibers that make up the second sheet-like fiber bundle are thicker and shorter than the fibers that make up the first sheet-like fiber bundle, they are stiffer, and these stiffer fibers more powerfully wipe away dust from narrow crevices, and the dust that is thus wiped off is picked up by the finer fibers, which affords even more effective cleaning and also helps prevent the thick fibers from becoming entangled with the fine fibers.
  • the cleaning component may be produced by interposing a fiber bundle body composed of a first sheet-like fiber bundle and/or a second sheet-like fiber bundle between sheet-like fiber bodies that face each other when a sheet laminate is bent, and joining the fiber bundle body and the sheet-like fiber bundle where they are in contact with each other.
  • This cleaning tool can be constituted such that the distal ends of the fibers that make up the fiber bundle body are above the upper end of the bulky component. Therefore, with this cleaning tool, any dust or the like that is above the bulky component can be efficiently wiped away with the fiber bundle body.
  • the sheet laminate may be produced by sandwiching the sheet-like fiber bundle with the sheet, and joining the sheet body to the sheet-like fiber bundle so as to cover the surface on the opposite side at the location of the joining portion.
  • the sheet-like fiber bundle may comprise a plurality of first sheet-like fiber bundles and/or a plurality of second sheet-like fiber bundles.
  • the sheet-like fiber bundle may be produced by alternately laminating first sheet-like fiber bundles and second sheet-like fiber bundles.
  • the sheet-like fiber bundles are such that dust is efficiently wiped away by the thicker, stiffer fibers that make up the second sheet-like fiber bundle, while the dust that has been wiped off is picked up by the finer fibers that make up the first sheet-like fiber bundle, so the cleaning component is able to clean more effectively. Also, these sheet-like fiber bundles effectively contribute to preventing the entanglement of the thick fibers with the fine fibers.
  • the sheet may be composed of a nonwoven cloth.
  • the sheet has a strip component
  • fine dust can be efficiently picked up by the fibers of the nonwoven cloth that makes up the strip component.

  • the present invention also provides a method for manufacturing a cleaning component for a cleaning tool, wherein a sheet-like fiber bundle produced by bundling fibers in the form of a sheet is laminated with a sheet having a strip component, these are partially joined to form a sheet laminate, and the sheet laminate is then bent along its joining portion so that the sheet-like fiber bundle is bent double at the joining portion, thereby producing a bulky component formation portion, after which the sheet having the strip component is bent back toward the sheet-like fiber bundle on the opposite side so as to surround the bulky component formation portion, and further the bulky component formation portion is bent so that the sheet-like fiber bundle side is on the inside, and the sheet-like fiber bundle and the sheet having the strip component are joined and integrated so that the contact surfaces of the sheet-like fiber bundles are joined to each other.
  • the method for manufacturing a cleaning component of the present invention makes it easy to provide a cleaning tool that provides sufficient cleaning performance even in the cleaning of narrow crevices.
  • the present invention provides a method for manufacturing a cleaning component for a cleaning tool, comprising the steps of making notches for forming a strip in a long sheet used for forming a sheet having a strip component; forming a joining portion by joining, in the sheet width direction of the sheet, a long laminate sheet obtained by laminating a long sheet that has been notched for forming a strip, first with a long sheet-like fiber bundle produced by bundling fibers in the form of a sheet, and then with a substrate sheet for supporting the sheet-like fiber bundle; obtaining a laminated sheet for forming a cleaning component, by slitting the long sheet laminate between the joining portions; forming a bulky component formation portion by cutting out one of the side portions flanking the joining portion of the sheet having a strip component in the laminated sheet for forming a cleaning component, cutting out both side portions flanking the joining portions of the substrate sheet, and then bending along the joining portions so that sheet-like fiber bundle is folded double, and joining so that the joining portions are tubular in

  • the nonwoven cloths 47a, 47b, and 47c are played out while being layered over one another, and a cutter roll 50 makes a plurality of cuts 52, for forming a strip component in the lengthwise direction, in the resulting laminate 51 of the nonwoven cloths 47a to 47c (Fig. 15A).
  • a plurality of blades are provided around the peripheral surface of the cutter roll 50 for making the cuts 52, and if gaps are provided to the blades, then non-continuous cuts 52 can be formed in the nonwoven cloth laminate 51 as shown in Fig. 15A.
  • Providing non-continuous cuts 52 maintains the sheet form of the nonwoven cloth laminate 51.
  • the nonwoven cloth laminate 51 is then laminated with the sheet-like fiber bundle 48 and the substrate sheet 49 to form a sheet laminate 53, but it is preferable for perforations 55 to be formed in the nonwoven cloth laminate 51 as shown in Fig. 15B with a perforating roller 54 prior to the formation of the sheet laminate 53. It is also preferable to provide perforations 57 (Fig. 17) in the substrate sheet 49 with a perforating roller 56 prior to the formation of the sheet laminate 53.

  • the perforations 57 provided to the substrate sheet 49 are preferably formed so as to be located at both sides flanking the joining portions 58. If the width of the sheet-like fiber bundle 48 constituting the sheet laminate 53 is less than the width of the nonwoven cloths 47a to 47c and the substrate sheet 49, as shown in Fig. 16, the ends of the sheet-like fiber bundle 48 will not be exposed at the joining portion ends 58a, which is preferable because it facilitates the work of inserting the support rods of the handle component (discussed below) in the handle insertion components 6 formed by putting the joining portions 58 in the form of bulky tubes.
  • the sheet laminate 53 in which the joining portions 58 have been formed is cut between the joining portions 58 with a cutting roll 61 as shown in Fig. 15C, forming a laminated sheet 62 for forming a cleaning component (Fig. 17).

  • a laminated sheet 62 for forming a cleaning component Fig. 17
  • one of the side portions flanking the joining portion 58 of the nonwoven cloths 47a to 47c of the sheet in the laminated sheet 62 for forming a cleaning component is cut out from the perforations 55, and both side portions flanking the joining portion 58 of the substrate sheet 49 are cut out from the perforations 57.
  • 49a in Fig. 18 is the remainder of the cut substrate sheet 49.
  • the cleaning component formation-use laminated sheet 62 obtained by cutting out one of the side portions flanking the joining portion 58 of the nonwoven cloths 47a to 47c and both side portions flanking the joining portion 58 of the substrate sheet 49 is then bent along the joining portion 58 so that the sheet-like fiber bundle 48 is folded over itself as shown in Fig. 19, and then the joining portion 58 is joined so as to become a bulky tubular component 63 as shown in Fig. 20, thereby forming the handle insertion component 6.
  • the cleaning component formation-use laminated sheet 62 is bent so that the sheet-like fiber bundle 48 side is on the inside, and the bent portions are joined together to obtain the cleaning component 1.
  • This manufacturing method differs from the first manufacturing method described above in the order in which the handle insertion component 6 is formed in the manufacturing process, but there is substantially no difference in the structure of the resulting cleaning component 1.
  • the second method described above was for a case in which three layers of nonwoven cloth 47a to 47c and one layer of sheet-like fiber bundle 48 were laminated, but there may instead be just one or two layers of nonwoven cloth, or four or more layers may be used, and two or more layers of the sheet-like fiber bundle 48 may also be used.
  • the cleaning tool of the present invention is obtained by attaching the handle component 2 to the cleaning component 1 by inserting the support rods 5 of the handle component 2 into the handle insertion components 6 of the cleaning component 1 manufactured as above.
  • the cleaning component 1 is detachably attached to the handle component 2.
  • the material of the handle component 2 can be plastic, metal, wood, etc., but plastic is preferred because of its light weight and low cost.

  • a constitution such as this when the support rods 5 are inserted into the handle insertion components 6, the spacing between the support rods 5 is narrowed, and after their insertion into the handle insertion components 6, the restoring force of the support rods 5 creates an outward force, which holds the support rods 5 securely in the handle insertion components 6, so that the support rods 5 will not readily slip out of the handle insertion components 6 during cleaning.
  • serration-like notches 15 are provided on the outsides of the two support rods 5. It is preferable for the notch angle ⁇ of the notches 15 on the support rod 5 side to be a large angle, and for the notch angle ⁇ of the notches 15 on the grip component 14 side also to be a large angle.
  • notches 15 allows the two support rods 5 to be easily inserted into the handle insertion components 6, and also makes it less likely that the support rods 5 will come loose from the handle insertion components 6, and more effectively prevents the support rods 5 from slipping out of the handle insertion components 6 during cleaning.
  • the handle component 2 is constituted such that it can bend between the support rods 5 and the grip component 14, and so that the support rods 5 and the grip component 14 can both be fixed when these have been extended.

  • bearing holes 21 are provided in side walls 19 and 20 inside the recess 18 formed in the receiver 16
  • a shaft 24 provided to the side walls 22 and 23 of the insertion component 17 is supported in the bearing holes 21, which allows the grip component 14 to rotate.
  • a latching protrusion 26 is provided to the ceiling 25 of the receiver 16, and a latching recess 28 in which the latching protrusion 26 can fit is provided to the upper surface 27 of the insertion component 17.
  • the grip component 14 is rotated around the shaft 24 until the insertion component 17 goes into the recess 18, and the latching protrusion 26 inside the recess 18 fits into the latching recess 28 of the insertion component 17. This puts the grip component 14 and the support rods 5 in an extended state.
  • the latching protrusion 26 and the latching recess 28 are unlatched, allowing the grip component 14 and the support rods 5 to be folded up (Fig. 23).
  • the receiver 16 may instead be provided on the grip component 14 side, and the insertion component 17 provided on the support rod 5 side, and the latching protrusion 26 may be provided on the insertion component 17 side, and the latching recess 28 provided on the receiver 16 side.
  • Figs. 25A and 25B illustrate another embodiment of the handle component 2 used in the cleaning tool of the present invention.
  • anti-slip protrusions 45 are provided instead of the notches 15 used in the above example, to prevent the support rods 5 from coming loose from the handle insertion components 6.
  • This handle component 2 is constituted such that the two support rods 5 and the grip component 14 can be bent at a joining portion 29, and the grip component 14 can be extended.
  • the grip component 14 of the handle component 2 shown in Figs. 25A and 25B comprises a hollow outer casing 46 and a core component 30 that is stowed in the hollow part of the outer casing 46.
  • the core component 30 and the outer casing 46 are constituted such that they can slide in the lengthwise direction.
  • the grip component 14 is extended and lengthened by sliding the outer casing 46 and the core component 30 in the lengthwise direction.
  • a protrusion 31 is provided in the vicinity of the end of the core component 30 in the lengthwise direction, and fitting holes 32 and 33 in which the protrusion 31 fits are provided in the vicinity of both ends of the outer casing 46 in the lengthwise direction.
  • the protrusion 31 of the core component 30 fits into the fitting hole 33 at the rear end side of the outer casing 46.
  • the protrusion 31 of the core component 30 is fitted and fixed in the fitting hole 32 at the distal end side of the outer casing 46. Fitting the protrusion 31 into the fitting holes 32 and 33 fixes the grip component 14 at a specific length. When the grip component 14 is pulled out, the engagement of the protrusion 31 in the fitting hole 32 prevents the grip component 14 from being pulled out too far, which would cause the core component 30 to come out of the outer casing 46. As shown in Fig. 26A, when the protrusion 31 of the core component 30 has been fitted into the fitting hole 32 (or 33) of the outer casing 46, the outer casing 46 is latched to the core component 30 so that it will not move readily.
  • the portion of the end of the core component 30 where the protrusion 31 is provided is formed thin as shown in Fig. 26B, and when the grip component 14 is extended and retracted, the protrusion 31 can be easily pushed into the hollow part of the outer casing 46, and the protrusion 31 unlatched from the fitting hole 32 (or 33), by pressing on the protrusion 31 with a finger, allowing the core component 30 and the outer casing 46 to be slid relative to each other.
  • the handle component 2 shown in Figs. 25A and 25B is formed so that it can fold in two at the joining portion 29 between the grip component 14 and the support rods 5, and is provided with an anti-folding mechanism so that during use these components will be kept extended and not readily fold up.
  • the anti-folding mechanism comprises a stopper 34 formed slidably in the lengthwise direction of the core component 30, and a latching tab 37 extending from a side wall 36 of the joining portion 29 of the support rods 5.
  • the handle component 2 is prevented from folding up during use by latching the latching tab 37 onto the stopper 34.
  • the grip component 14 when the stopper 34 has been slid in the lengthwise direction of the core component 30 and pressed against the joining portion 29, the grip component 14 can be non-rotatably fixed with the grip component 14 and the support rods 5 in an extended state by latching the latching tab 37 on the stopper 34.
  • the latching tab 37 when the stopper 34 is slid toward the grip component 14, the latching tab 37 is unlatched from the stopper 34, allowing the grip component 14 to rotate around the rotational axis 38 of the joining portion 29.
  • the grip component 14 can be rotated about 180° and folded into a compact size.
  • a movement positioning mechanism is formed on the stopper 34 so that the stopper 34 will not move more than necessary when slid in the direction of being unlatched from the latching tab 37.

As shown in Fig.
  • the grip component 14 is in a rotatable state, so when the stopper 34 is slid in the direction of being unlatched from the latching tab 37, the protrusion 39 hits a latching wall 41 that blocks the joining portion 29 side in the groove 40 of the stopper 34, so that the stopper 34 cannot slide any farther.
  • a hemispherical protrusion 43 is provided to the bottom 42 of the joining portion 29
  • a hemispherical recess 44 for fittably supporting the hemispherical protrusion 43 is provided to the core component 30, and when the grip component 14 and the support rods 5 have been extended, as shown in Fig. 29A, the hemispherical protrusion 43 of the joining portion 29 fits into and is fixed in the hemispherical recess 44 of the core component 30.
  • the handle component 2 is to be folded up, as shown in Fig.
  • the grip component 14 is rotated by applying a slight force to it, whereupon the hemispherical protrusion 43 of the joining portion bottom 42 comes out of the hemispherical recess 44 of the core component 30, allowing the grip component 14 to be rotated and the support rods 5 and the grip component 14 to be folded in two.
