  • Publication number: 20120124763
    Abstract: It is an object of the invention to provide a hand-held mop in which a grip connected to a mounting part for mounting and supporting a mop body is prevented from being detached from the mounting part during cleaning operation. A hand-held mop 1 includes a mop body 2, a mounting part 10, and a grip 20. The mop body 2 has a pair of mop body portions 2a, and the mounting part 10 has a pair of mounting pieces 11 which are inserted into mounting spaces of the mop body portions 2a, and an insert 15. The grip 20 has a holding side 22 which defines an insert space 22a into which the insert 15 of the mounting part 10 is inserted. Further, a side opening 23 is formed in the holding side 22 of the grip 20, and a side projection 19 is formed on the insert 15 of the mounting part 10 and engaged in the side opening 23.

  • Publication number: 20120117744
    Abstract: A cleaning element holder of a cleaning tool includes a handle to be held by user's hand, and a pair of holding parts which extend from the handle in a longitudinal direction of the cleaning element holder. Each of the holding parts has deflection displacement characteristics around a connection between the handle and the holding part, at least in a first direction transverse to an extending direction of the holding parts and a second direction transverse to the first direction. When a load of 2.5 N is applied in the first direction to an end, the holding part deflects 15 to 80 degrees in the first direction, and when a load of 2.5 N is applied in the second direction to the end, the holding part deflects 25 to 55 degrees in the second direction.
