Abstract

A mop having a mop sheet holder member 2 of a short cylindrical shape and of a resiliently flexible material attached to the fore end of a handle stick 1. An axially extending sheet anchoring groove 12 is formed on the top side of the sheet holder member 2 to anchor therein opposite end portions of a mop sheet securely in cooperation with a sheet retainer arm pivotally movable into engagement with the sheet anchoring groove 12 from above.

Claims

1. A mop of the type having a handle stick, a sheet holder member attached to the fore end of said handle stick, a mop sheet replaceably fitted on said sheet holder member, and a sheet retainer member adapted to anchor the opposite end portions of said mop sheet on said sheet holder member, characterized in that said sheet holder member has a body generally formed in a relatively short cylindrical shape by the use of a flexible material and provided with an axially extending sheet anchoring groove on the upper side thereof, and said sheet retainer member is constituted by at least one retainer arm pivotally movable between an operative position where said retainer arm is engaged with said axial sheet anchoring groove on said sheet holder member for fixedly anchoring opposite end portions of said mop sheet therein and a free position where said retainer arm is disengaged from said sheet anchoring groove on said sheet holder member for releasing said mop sheet.

2. A mop as defined in claim 1, wherein said handle stick is substantially constituted by a single rod-like member and pivotally connected at its fore end substantially to a center portion of said sheet holder member on the upper side thereof, and a couple of retainer arms are pivotally supported at the respective base ends at the opposite lateral sides of said handle stick.

3. A mop as defined in claim 1, wherein said handle stick is constituted by a couple of stick members, a first stick member and a second stick member, connected with each other in such a way as to be openably foldable one on the other, said first stick member being attached to said sheet holder member with the respective axes substantially in parallel relation with each other, and said second stick member being arranged to serve as a retainer arm to be engaged with said sheet anchoring groove on said sheet holder member when folded and closed on said first stick member.

4. A mop as defined in any of claims 1 to 3, wherein said sheet holder member has a body generally of a hollow cylindrical shape.

5. A mop as defined in claim 1, wherein said mop sheet fitted on said sheet holder member is pleated except opposite end portions thereof for the purpose of increasing a substantial sheet thickness in mopping operations.
