  • a cleaning tool of this type having a cleaning element it is required to provide an effective technique for enhancing its cleaning effect.
  • This invention can be applied to the construction of cleaning tools for cleaning regions to be cleaned (floors, walls, ceilings, external walls, posts, furniture, clothes, curtains, blinds, bedding, lighting, electrical cords, home electric appliances, etc.) inside and outside of houses, apartments, ⁇ buildings, factories, vehicles, etc. or regions of human body parts to be cleaned. These regions to be cleaned may be either flat or curved, uneven or stepped.
  • a cleaning tool is used for cleaning an object to be cleaned and includes at least a cleaning element holder and a cleaning element.
  • the cleaning element holder is an elongate member.
  • the cleaning element holder includes a grip to be held by a user and a plurality of holding elements extending from the grip in parallel in a longitudinal direction. In order to extend in "parallel” here, the holding elements are required to be disposed at least side by side.
  • Such a manner of extending in parallel includes the manner in which a plurality of the holding elements are disposed in parallel, and the manner in which the distance between two adjacent holding elements is decreased toward the front end.
  • the cleaning element is designed as a member to be attached to the elongate cleaning element holder.
  • the cleaning element includes a plurality of elongate split cleaning parts which have respective insert regions for receiving the holding elements, and the cleaning element has a space into which the object to be cleaned can be inserted between adjacent ones of the split cleaning parts. The object inserted into this space is cleaned while being held between the split cleaning parts.
  • the manner of being “split” here widely includes the manner in which a predetermined split cleaning part is disposed in its entirety or in part across the space from the other split cleaning part, and the manner in which a predetermined split cleaning part is integrally connected to the other split cleaning part.

  • the fiber assemblies of the adjacent ones of the split cleaning parts overlap each other in the space in a direction transverse to the longitudinal direction of the split cleaning parts.
  • the overlapped state of the fiber assemblies between the split cleaning parts in the space is required to be realized at least in the inserted state of the holding elements into the insert regions.
  • the fiber assemblies of the split cleaning parts may overlap each other, or they may be spaced apart from each other without overlapping. Further, the number and combination of the fiber assemblies and nonwoven fabric sheets which are overlaid one on the other and bonded together can be selected as necessary.
  • a shape-retaining function is provided by overlapping of the fiber assemblies between the adjacent split cleaning parts.
  • the entire cleaning element can be prevented from drooping, and unnecessary clearance can be prevented from being formed in the space.
  • the contact area between the object to be cleaned and the split cleaning parts can be increased by wrapping the object to be cleaned between the split cleaning parts.
  • the cleaning effect of the object to be cleaned which is inserted into the space can be enhanced.
  • deterioration of the appearance of the cleaning tool which may be caused by unnecessary clearance formed in the space can be prevented.
  • users can be convinced that the cleaning element has a high cleaning effect and the user's cleaning motivation can be effectively enhanced.

With such construction, the space can be formed such that, when the holding elements are inserted into the insert regions, the object to be cleaned can be inserted into the space while the fiber assemblies of the split cleaning parts overlap each other in the space in a direction transverse to the longitudinal direction of the split cleaning parts.

  • the dust etc. D is adsorbed by the fiber assemblies 117 of the first adsorbing region 123a.
  • the cleaning element 110 is further moved, as shown in FIG. 15 , the dust etc. D hiding behind a projection is scraped out by the strips 118a of the front sheets 118 between the first adsorbing region 123a and the second adsorbing region 123b, and adsorbed by the fiber assemblies 117 of the second adsorbing region 123b.
  • the cleaning element 110 is further moved, as shown in FIG. 16 , the dust etc.
  • the dust etc. D in a depression is adsorbed by the fiber assemblies 117 of the first adsorbing region 123a. Even if the dust etc. D is not adsorbed by the fiber assemblies 117 of the first adsorbing region 123a, the dust etc. D is scraped out by the strips 114a of the holding sheets 114 between the first adsorbing region 123a and the second adsorbing region 123b, and then adsorbed by the fiber assemblies 117 of the second adsorbing region 123b. Or even if the dust etc. D is not completely scraped out, the dust etc. D is moved rearward within the depression and adsorbed by the fiber assemblies 117 of the second adsorbing region 123b. Further, the dust etc.
  • the cleaning element 110 In an operation of wiping a wide plane surface of the object to be cleaned W, when the user's wrist is unstable or when the object to be cleaned W is up high, it is assumed that the cleaning element 110 is operated in an inclined position with respect to the surface of the object to be cleaned W. Therefore, in this embodiment, as shown in FIG. 17 , the cleaning element 110 has four adsorbing regions 123a, 123b, 123c, 123d with respect to the object to be cleaned W, so that, for example, the dust etc. D which cannot be adsorbed by the first adsorbing region 123a or the second adsorbing region 123b can be adsorbed by the third adsorbing region 123c or the fourth adsorbing region 123d.
  • the cleaning element 110 is described as having the pair of right and left split cleaning parts 123.
  • the number of parts corresponding to the split cleaning parts 123 can be appropriately set in the range of two or more.
  • FIGS. 18 and 19 other embodiments are described.
  • a cleaning tool 200 of the embodiment shown in FIG. 18 is constructed such that a cleaning element holder 230 having elongate three holding portions 242 is attached to a cleaning element 210 consisting of three split cleaning parts 123. Specifically, in attachment of the holder, the holding portions 242 are inserted into the insert regions 115 of the split cleaning parts 123.
  • the three split cleaning parts 123 are disposed in parallel to each other such that the centers of their sections are located at the respective apexes of a predetermined triangle.
  • a cleaning tool 300 of a further embodiment shown in FIG. 19 is provided such that a cleaning element holder 330 having four elongate holding portions 342 is attached to a cleaning element 310 consisting of four split cleaning parts. Specifically, in attachment of the holder, the holding portions 342 are inserted into the insert regions 115 of the split cleaning parts 123.
  • the four split cleaning parts 123 are disposed in parallel to each other such that the centers of their sections are located at the apexes of a predetermined square.
  • the cleaning tool 200 shown in FIG. 18 and the cleaning tool 300 shown in FIG. 19 can also provide the same effect as the above-described cleaning tool 100. Further, the cleaning tools 200, 300 may be constructed such that three or four split cleaning parts 123 are disposed in parallel to each other on a predetermined straight line.
  • each of the split cleaning parts 123 of the cleaning element 110 is designed to have a generally circular or elliptical section.
  • this section it is necessary for this section to form the generally circular or elliptical shape in its entirety or in part.
  • the section of the split cleaning part may also have a shape of one or more fans which forms part of a circular form.
  • This construction is shown in a cleaning element 410 of a further embodiment shown in FIG. 20 .
  • each of split cleaning parts 423 has an outside region and an inside region which have respective sections of fan-like shapes which form part of circular shapes of different diameters.
  • This construction can be realized, for example by changing the position of the fusion bonding lines 120, 121, or the length of the holding sheets 114, the fiber assemblies 117 and the front sheets 118 according to location. With such construction, the outside and inside regions of the split cleaning parts 423 can be effectively provided with different cleaning capabilities.
  • the cleaning element 110 is formed by a sheet-like nonwoven fabric and a fiber assembly.
  • the cleaning element 110 may be formed by either one of the sheet-like nonwoven fabric and the fiber assembly.
