Extendable improved cleaning system and method
View Patent ↗A system for cleaning includes a handle and a head having a cleaning surface. The head is connected to the handle and is extendable to selectively widen or narrow the cleaning surface. A gear is fixedly connected to the handle and rotatingly connected to the head, so that twist of the handle rotates the gear. A first series of extension gears operably connect to the gear, and a second series of extension gears also operably connect to the gear. Rotation of the gear via the handle, rotates the first series and the second series. A first head extension is operably connected to the first series, such that rotation of the first series swings the first head extension into laterally aligned extension of the head. A second head extension is operably connected to the second series, such that rotation of the second series swings the second head extension also into laterally aligned extension of the head. In such manner, twist of the handle rotates the gear, causing the first series and the second series to rotate, thereby swinging the first and second head extensions into laterally extended alignment in order to selectively widen (and conversely narrow) the cleaning surface of the head.
1. A system for cleaning, comprising:
a handle;
a head having a cleaning surface, the cleaning surface having a generally linear configuration, the head having a first end and a second end and being centrally connected to the handle, with the first end and the second end linearly and opposingly disposed in the head at extents of the generally linear cleaning surface thereof from the centrally connected handle;
wherein the head is linearly extendable at the first end and the second end to selectively widen the length of the linear configuration of the cleaning surface and contractable to selectively narrow the length of the linear configuration of the cleaning surface, to the limits of and within a range for the length of the cleaning surface from fully extended to fully contracted; and
a gear, connected to the handle and operably connected to the head, so that twist of the handle rotates the gear and thereby selectively linearly extends the length of the cleaning surface of the head at the first end and the second end of the head at opposing extents from the centrally connected handle.
2. The system of claim 1 , wherein reverse rotation of the gear selectively linearly contracts the length of the cleaning surface of the head at the first end and the second end of the head at opposing extents from the centrally located handle.
3. A system for cleaning, comprising:
a handle;
a generally linearly disposed cleaning head, having a central portion and dual extension portions, connected to the handle;
wherein the dual extension portions of the cleaning head are pivotally connected to the central portion of the cleaning head for extending generally laterally with respect to the central portion; and
opposing asymmetric gears, engagingly connected to the central portion and to respective ones of the dual extension portions, to actuate respective ones of the dual extensions into linearly extended positions on opposing sides of the central portion in order to extend the cleaning head.
4. The system of claim 3 , wherein the dual extension portions of the cleaning head are pivotally connected to the central portion of the cleaning head for contracting generally linearly with respect to the central portion after so extending generally linearly with respect to the central portion.
