  • the present invention relates to a cleaner designed to be used with an adhesive tape roll attached thereto, the adhesive tape roll formed of a tape-shaped base having at least one adhesive surface and wound around a center line in a tubular form.
  • Patent Literature 1 There is a known cleaner of this type in related art including a pair of shaft receiving members inserted into cylindrical holes of an adhesive roller on both sides and a holder having a pair of holding portions that hold the shaft receiving members and a body that supports the holding portions.
  • Each of the shaft receiving members described above includes a tubular fitting portion that is inserted into the corresponding cylindrical hole of the adhesive roller, a shaft receiving plate that covers one open end of the fitting portion, and a shaft receiving hole that passes through the shaft receiving plate along the cylindrical hole.
  • the pair of holding members include a pair of rod-shaped legs that extend from the body, a disk-shaped portion that is provided at an end of each of the legs and can be disposed such that the disk-shaped portion faces the corresponding shaft receiving plate, and a rotary shaft that protrudes from the disk-shaped portion and can fit into the corresponding shaft receiving hole.
  • the shaft receiving members are inserted into both ends of the adhesive roller, the pair of holding portions of the holder are forced to separate from each other, and the rotary shafts are fit into the shaft receiving holes with the shaft receiving members facing the holding portions.
  • the pair of holding portions of the holder are forced to separate from each other, protrusion/recess fit between the rotary shafts and the shaft receiving members is released, and the shaft receiving members are detached from both ends of the adhesive roller.
  • Patent Literature 1 JP 2004-57602 A
  • the cleaner of related art described above has a problem of complicated operation of attaching and detaching the adhesive roller because the attachment and detachment of the adhesive roller requires a series of actions of detachably fitting the shaft receiving members to both ends of the adhesive roller, forcing the pair of holding portions of the holder to separate from each other, and detachably fitting the rotary shafts of the pair of holding portion into the shaft receiving holes of the corresponding shaft receiving members as described above.
  • the present invention has been made in view of the problem described above, and an object of the present invention is to provide a cleaner that allows a user to readily attach and detach an adhesive tape roll and has improved strength that prevents the cleaner from being easily broken.
  • a cleaner according to the present invention has been made to achieve the object described above and includes a rod-shaped core member inserted into a cylindrical hole of an adhesive tape roll formed of a tape-shaped base having at least one adhesive surface and wound around a center line in a tubular form and a body member having a first end support portion and a second end support portion for supporting a first end portion and a second end portion in an axial direction of the core member.
  • the first end portion of the core member includes shaft portions that allow the core member to be movable relative to the body member with the first end portion serving as a pivotal point.
  • the second end portion of the core member is configured to be detachably locked by the second end support portion of the body member.
  • the motion of the core member is restricted in a state in which the second end portion is locked by the second end support portion and is allowed in a state in which the locked state is released.
  • the body member includes a top wall portion that is disposed such that the top wall portion faces the core member but is set apart therefrom in a radial direction thereof and a pair of sidewall portions that extend from the top wall portion toward the core member and face each other in the radial direction of the core member.
  • the first end support portion of the body member includes the pair of sidewall portions and a portion of the top wall portion that is interposed between the pair of sidewall portions.
  • the pair of sidewall portions rotatably support the shaft portions in an area surrounded by the top wall portion and the pair of sidewall portions.
  • the second end portion of the core member behaves as a free end, and the core member is movable relative to the body member with the first end portion serving as a pivotal point.
  • the second end portion of the core member locked by the second end support portion of the body member is released, and the core member is moved relative to the body member with the first end portion serving as a pivotal point to a desired position to sufficiently separate the second end portion of the core member and the second end support portion of the body member from each other, whereby the adhesive tape roll can be readily attached to or detached from the core member by using the cylindrical hole of the adhesive tape roll in the direction from the second end portion toward the first end portion or in the opposite direction.
  • the first end support portion rotatably supports the shaft portions between the pair of sidewall portions in an area surrounded by the top wall portion and the pair of sidewall portions, whereby a shaft receiving structure that supports the shaft portions can have increased rigidity and improved strength, and hence breakage of the shaft support structure can be suppressed or prevented.
  • the motion of the core member with the first end portion serving as a pivotal point is restricted in the state in which the second end portion of the core member is locked by the second end support portion of the body member. Therefore, to use the adhesive tape roll, the second end portion of the core member to which the adhesive tape roll is attached can be locked by the second end support portion of the body member to restrict the motion of the core member with the first end portion serving as a pivotal point, whereby the adhesive tape roll attached to the core member can be appropriately rotated when used.
  • the first end support portion of the body member may include a reinforcing wall portion that connects the pair of sidewall portions to each other along the direction in which they face each other, and the reinforcing wall portion may be configured to stand on the top wall portion.
  • the first end support portion rotatably supports the shaft portions between the pair of sidewall portions in an area surrounded by the pair of sidewall portions and the reinforcing wall portion, whereby the shaft support structure that supports the shaft portions can have increased rigidity and improved strength, and hence breakage of the shaft support structure can be suppressed or prevented.
  • the second end portion of the core member locked by the second end support portion of the body member behaves as a free end, and the core member is movable relative to the body member with the first end portion serving as a pivotal point.
  • the second end portion of the core member locked by the second end support portion of the body member is released, and the core member is moved relative to the body member with the first end portion serving as a pivotal point to a desired position to sufficiently separate the second end portion of the core member and the second end support portion of the body member from each other, whereby the adhesive tape roll can be readily attached to or detached from the core member by using the cylindrical hole of the adhesive tape roll in the direction from the second end portion toward the first end portion or in the opposite direction.
  • the first end support portion rotatably supports the shaft portions between the pair of sidewall portions in an area surrounded by the top wall portion and the pair of sidewall portions, whereby the shaft receiving structure that supports the shaft portions can desirably have increased rigidity and improved strength, and hence breakage of the shaft support structure can be suppressed or prevented.
