Definitions

  • the present invention relates to devices for cleaning windows and other hard surfaces. More particularly, it relates to "all-in-one" type devices that deliver a cleaning fluid, work the fluid along the surface being cleaned, and remove the used liquid.
  • U.S. patent 1,376,195 disclosed an all-in-one type window cleaning device.
  • the device had a reservoir containing cleaning liquid that impregnated a moistening element/sponge.
  • the device collected the used liquid in an adjacent catch reservoir on the device.
  • U.S. patent 2,722,701 disclosed a device which supplied a cleaning liquid and collected at least some of it in an adjoining absorbent pad region.
  • the invention provides a cleaning implement for cleaning a surface. It has a handle and a support head mounted on the handle for rotation.
  • the support head has at least two sides that can be selectively positioned adjacent the surface.
  • the substrate is suitable to deliver cleaning fluid to the surface.
  • the support head has at least three sides that can be selectively positioned adjacent the surface, and the absorbent sheet removably covers at least two of them.
  • the absorbent sheet can be part of a stack of such absorbent sheets, and the stack can be removably mountable to the support head along those two sides.
  • a first sheet of the stack can be torn off from the stack after use to expose a fresh second sheet of the stack.
  • the first sheet of the stack can have weakenings and tabs to facilitate tearing off of the first sheet from the stack.
  • each absorbent sheet comprises an outer absorbent layer laminated or otherwise linked to an inner barrier layer.
  • the substrate be a porous material that readily releases impregnating liquid upon contacting a surface. This can be anything from a sponge-like material to a fibrous material. It is particularly preferred that the substrate be made of a fibrous material selected from the group consisting of polyester fiber, polypropylene fiber, cellulose acetate fiber, and bonded polyolefin fiber, and the substrate be impregnated with a window cleaning fluid. Also possible is using melamine foam materials.
  • Such a substrate is configured to deliver cleaning fluid in a controlled manner. It also provides a scrubbing surface for working in the fluid along the window being cleaned. Further, the substrate can be selected to be suitable to reabsorb at least part of the used cleaning liquid, and filter it so as to be able to reuse it to some extent.
  • head pressure can be defined as the pressure of the liquid in the substrate material.
  • Each type of substrate material can hold up to some maximum height of the liquid in a vertical direction (regardless of the thickness of the material) before the liquid begins to drool out of the material. Therefore, at greater than the maximum head pressure of the material, the force of gravity is greater than the ability of the material to hold the liquid.
  • the maximum head pressure can be determined by loading various sizes of the substrate material to saturation with a liquid of interest and then placing the pieces of material on end to check which vertical heights leak and which vertical heights retain liquid. With the types of fibrous material we prefer to use we have found that once the pieces of material begin to exceed about 8 cm a drool problem can exist for typical window cleaners. [0019] With some deeming liquids it is desirable to cover the substrate, or a cartridge containing the substrate, between uses to minimize evaporation from the substrate. This can be achieved with a removable cover. That cover will also limit evaporation prior to the first use, albeit prior to the first use a sealed packet may be the preferred way to protect the cartridge.
  • the support head is essentially triangular in cross section (most preferably isosceles triangular). This permits free rotation of the support on its axis for about 300 degrees of rotation. Additional rotation is prevented as the longer end of the triangle will contact a structure of the handle before further rotation can occur. This helps insure that the support head surfaces are optimally aligned with typical vertical surfaces being cleaned (e.g. a window).
  • Structures are also preferably provided to facilitate quick attachment and removal of the absorbent sheet(s).
  • Each sheet can be provided with slots adjacent its ends which can hook onto corresponding projections on the support head. Some of the projections can be on a side of the support head that is pivotably mounted to another side. The attachment of the sheet(s) can be made when the sides are pivoted open and the sheet stack can then be dragged into a tight alignment by the closing of the sides.
  • the substrate is preferably mounted to a cartridge housing, with the cartridge housing being mounted to the support head and holding a plurality of additional substrate pieces in separate wells. Further, a portion of the substrate facing the surface to be cleaned can be segmented with non-porous barriers between the segments. These structures further facilitate cleaning while minimizing drool.
  • the invention provides a refill cartridge for such a cleaning implement.
  • a cartridge housing and a porous substrate mounted to the housing.
  • the substrate is impregnated with a cleaning liquid and the substrate is suitable to deliver the cleaning fluid to the surface.
  • the substrate is formed of a fibrous material selected from the group consisting of polyester fiber, polypropylene fiber, cellulose acetate fiber, and bonded polyolefin fiber, and the substrate is impregnated with a window cleaner.
  • the substrate may have an applicator portion and a reservoir portion, where the reservoir portion has at least two separated portions, the two separated portions each being a separate piece of a porous absorbent material impregnated with a cleaning liquid.
  • the reservoir portion can be an integral portion of the same block which has the applicator portion.
  • the applicator portion can be divided into segments.
  • the substrate is sized so as to avoid gravity (via head pressure) alone causing the cleaning liquid to drool out of the substrate.
  • the support head In operation the support head is first rotated on its own longitudinal axis to align the substrate with a surface to be cleaned (e.g., a window glass surface). By pressing the substrate against the window cleaning liquid is applied to the window. [0027 ] The support head is then turned to align one of the sheet sides with the window and the sheet along that side is then pressed against and wiped on the window. This may be for a crude drying function, or, depending on the nature of that portion of the sheet, may also provide some scrubbing function or other function as well. If desired, the support head can then be turned again so that the other sheet side can be pressed against and dragged on the surface. This can then perform a final drying.
  • a surface to be cleaned e.g., a window glass surface.
  • the exposed sheet When the exposed sheet has become saturated or too dirty, it can be torn off. Tear weakenings can be provided transversely along a strip adjacent the slots to facilitate this. The barrier layer of the top exposed sheet prevents the sheet then being exposed from being prematurely soiled.
  • the exposed material along one side of the support head can be of a first nature and the material adjacent another side can be of another nature. See ejj ⁇ U.S. patent 6,766,522.
  • two separate sheets, or two separate stacks of sheets may be used so that a sheet on one side can be separately removed or installed relative to the sheets along the other side.
  • the sheets covering the two sides may have identical or different functional characteristics to perform either identical or different functions, at least one which is absorbing used cleaning liquid from a surface being cleaned and drying the surface.
  • the sheets in the stack may be optionally attached together, for example, by heat sealing at two opposing ends of the sheets.
  • Each tear-off sheet may optionally have other features that facilitate the removal of the sheet.
  • the sheets may also have tabs to facilitate the start of the tearing.
  • the handle provided may be a one-piece handle or a multi-piece elongatable handle.
  • a handle having a fork and two telescoping extension parts is preferred.
  • Such devices are suitable for cleaning building windows. However, they can also be used for cleaning automobile windows and other hard surfaces.
  • a variety of cleaning liquids can be used ranging from water to specialized window cleaners (e.g. Windex® brand window cleaner), to other hard surface cleaning or treatment fluids.
  • the liquid may have other functions besides just cleaning (e.g., polishing, antibacterial treatment, insect treatment, etc.). Thus, the nature of the liquid is not critical to the invention.
  • the portion of the substrate material adjacent the window to be cleaned (“the applicator") is preferably of sufficient integrity so that it does not degrade and leave residue while being rubbed against the window. It is also preferred that this portion of the substrate material have some abrasiveness or roughness to provide scrubbing to the surface.
  • the substrate is most preferably in slab-like segments of a porous absorbent material, such as a fibrous filtering material selected from the group consisting of polyester fiber, polypropylene fiber, cellulose acetate fiber, and bonded polyolefin fiber. Particularly preferred absorbents are polyester fiber materials, polypropylene fiber materials, cellulose acetate fiber materials, and bonded polyolefin fiber materials available from Filtrona Richmond Inc.
  • the substrate can be frictionally fit into a cartridge housing.
  • a variety of ways are available to mount the cartridge housing to the support head such as snap fits, hooks, clamps or other structures.
  • All of the cleaning liquid may be in the substrate.
  • additional cleaning liquid may be positioned in an adjacent reservoir of the cartridge unit so as to resupply and refresh the substrate.
  • the substrate can form a type of cap over the reservoir(s).
  • Another possibility is for additional strips or pieces of the substrate to form a type of reservoir which feeds the applicator portion.

  • a generally triangular cross section cleaning implement is shown having a support head (generally 10) with one side being a substrate 12 for applying a cleaning liquid, and two sides 13A/13B being covered by a stack of absorbent tear-off sheets 14.
  • a handle structure (generally 16) having a lower end 18 and an upper end 19 linked to a fork 20.
  • the support head 10 is rotatably mounted between the arms 40 and 42 to align the impregnated substrate 12 with a surface to be cleaned (such as a window glass surface 22).
  • a surface to be cleaned such as a window glass surface 22.
  • the substrate 12 can be pressed against and dragged on the window glass surface 22, thereby applying cleaning liquid to the surface and to some extent scrubbing the surface to help remove stains and other deposits.
  • the support head 10 can be rotated as shown in FIGS. 2 and 4 to align one of the tear-off sheet sides with the glass surface 22.
  • a sheet 14 can then be pressed against and dragged on the surface to absorb most of the used liquid.
  • Over- rotation of the support head 10 is blocked with contact between the elongated point of the support head's triangle and the linking structure 44 of the fork 20.
  • the support head can be rotated in the opposite direction through about 300 degrees of rotation so that the opposite side of a sheet 14 can finish the drying process (see FIG. 4).
  • the top tear-off sheet is sufficiently saturated or soiled, it can be torn off to expose a fresh sheet underneath.
  • the preferred handle has separate segments 24, 26, and 28 that are linked together. With this handle segments 26 and 28 can telescope to provide varied length options.
  • the segment 28 may be locked into either a compact position (dotted lines in FIG. 1) for easy storage and transportation, or an extended position for additional reaching capability. This can be achieved via a pair of outwardly biased button tabs 30 and 32 on the segment 26 and corresponding openings on the adjacent parts. When these buttons are aligned with their corresponding openings they prevent disass ⁇ mbly or relative sliding movement. Pressing the buttons radially inward permits disassembly or relative sliding movement.
