Definitions
- This invention relates generally to cleaning devices and more particularly to floor mops.
- Floor mops also referred to as "dust mops” have been developed in several forms in the past for cleaning floors or like surfaces.
- string mops have been in common usage, such as the cotton or cotton/synthetic yarn products available from Tu-way American Group of Rockford, Ohio; Paragon Mop Co. of Charlotte, North Carolina; the Zephyr Manufacturing Co. of Sedalia, Missouri; and Wilen Co., of Atlanta, Georgia.
- Such floor mops are effective, but are relatively expensive and are therefore generally repeatedly reused and cleaned, and must eventually be repaired or replaced.
- the DoodledusterTM system (shown in Figures 1, 2 A and 2B) includes a floor mop 10 having a mop head 12 and a handle 14 for manipulating the floor mop.
- the handle 14 is pivotally connected to the mop head by connection member 16, such as is described in U.S. Patent No. 3,850,533 entitled "Positional Universal Joint".
- the structure of the mop head is described in U.S. Patent No. 4,225,998 entitled "Dust Mop Frame".
- the mop head includes a central portion 20 having a top surface 22, an opposing bottom surface 24, a longitudinal leading surface 26, a longitudinal trailing surface 28, and opposing end surfaces 30 and 32, respectively.
- Toggle assemblies 34 are mounted on top surface 22 of the central portion in spaced aligned pairs.
- a rectangular segment 26 of dusting fabric is applied to the bottom surface 24 and the opposing longitudinal edges 38 and 40.
- the dusting fabric is engaged with the toggle assemblies 34 along opposing longitudinal edges to secure the dusting fabric to the mop head.
- One major surface 37 of the dusting fabric 36 is presented for encountering a surface (not shown) for cleaning the surface.
- the opposite major surface 39 faces bottom surface 24 of the mop head and, as shown in Figure 2 A, longitudinal edge 38 extends beyond leading surface 26 and opposing longitudinal edge 40 extends beyond trailing surface 28.
- Toggle assembly 34 includes toggle member 44 hingedly connected (as at 46) by aligned hinge members projecting from the top surface 22 of the mop head.
- Toggle members 44 include a handle portion 50 for manipulating the toggle member to a first, open position (as at the right side of Figure 2A) permitting the edge 38 of the cleaning fabric 36 to be placed over top surface 22; the toggle member 44 may then be shifted (by rotation in direction 52) to a second, closed position (as at the left side if Figure 2 A, and in Figure 2B) to engage and retain the cleaning fabric on the mop head, by way of projecting tang 54.
- Tang 54 is aligned with groove 56 formed in top surface 22. Tang 54 and groove 56 cooperatively frictionally engages the cleaning fabric.
- a spring member 60 is mounted on the top surface 22 of the mop head to resiliently frictionally engage the toggle member and retain it in either the open or closed positions.
- the floor mop is used to clean a floor and when the cleaning capacity of exposed cleaning surface 37 is reached, the toggle assemblies are disengaged, the dusting fabric removed, reversed, reinstalled and the toggle assembles reengaged, enabling the floor mop to be used for further cleaning.
- the DoodledusterTM system while having its own utility, does exhibit certain limitations. As previously discussed, the handling of a used dusting fabric is particularly undesirable in environments where the handler may be exposed to chemical or biological hazards when handling the dusting cloth. Of course, safety measures such as gloves or other like protective devices may be employed, but at the expense of increased cost and decreased convenience to the user. Another problem is that an undesirably large portion of the dusting cloth may not be utilized at all to clean the floor, but is required merely to extend to reach the toggle assemblies 34 on the top surface 22 of the central portion 20 of the mop head to secure the dusting cloth to the mop head. This inefficiently utilizes the material of the dusting cloth and undesirably increases the cost of using the DoodledusterTM cleaning system.
- the present invention provides a floor mop for cleaning a floor.
- the floor mop includes a mop head having a longitudinal leading edge, a longitudinal trailing edge, a first end and an opposing second end, a first cleaning support surface and an opposing second cleaning surface.
- a flexible cleaning sheet is provided having a first cleaning surface and an opposing second cleaning surface and a longitudinal attachment edge.
- Securing means are provided for releasably attaching a portion of the cleaning sheet to the mop head adjacent to and parallel to the attachment edge of the cleaning sheet, leaving a major portion of the cleaning sheet free.
- the floor mop includes a handle member adapted for manual engagement and means are provided for pivotally connecting the handle member to the mop head enabling the mop head to be shifted by manipulating the handle member between a first position with the first cleaning surface of the mop head presented to the floor with the cleaning sheet inte ⁇ osed between the first cleaning support surface and the floor and the free portion of the cleaning sheet extending from the attachment means towards the trailing edge of the mop head so as to present the first cleaning surface of the cleaning sheet to encounter the floor as the mop head is moved in relation thereto, and a second position with the second cleaning surface of the mop head presented to the floor with the cleaning sheet interposed between the second cleaning support surface and the floor and the free portion of the cleaning sheet extending from the attachment means towards the trailing edge of the mop head so as to present the second cleaning surface of the cleaning sheet to encounter the floor as the mop head is moved in relation thereto.

- Mop head 102 includes a longitudinal leading edge 110, a longitudinal trailing edge 112, opposing ends 114 and 116, first cleaning support surface 118 and second cleaning support surface 120 (shown in Figure 4C).
- the leading edge 110 and trailing edge 112 are parallel to longitudinal axis 122.
- First cleaning support surface 118 and second cleaning support surface 120 are also preferably parallel to each other.
- the ends 114,116 are tapered from the leading edge 110 to the trailing edge, as shown in Figure 3. This arrangement facilitates access to corners or like locations during use of the floor mop.
- a cleaning sheet or dusting sheet 140 (shown in Figs. 6 and 6A) is provided to clean a surface, such as a floor (not shown) through sliding contact therewith.
- the cleaning sheet 140 may be formed from any suitable flexible material adapted to collect the substance that is to be cleaned from a surface.
- the cleaning material may be woven, non-woven, or have a sponge-like structure, or any other suitable arrangement.
- a non-woven fabric may be employed that is constructed from processes such as by spunbonding or by fibrillation.
- the cleaning sheet will be adapted to collect particulate matter, such as dust, from a floor or other like surface to be cleaned and retain most particulate matter on or in the sheet member.
- the floor mop is more particularly referred to as a dust mop. It is also possible to select a material to construct the cleaning sheet of a material that absorbs liquid materials. For instance, it is possible to select a material that is hydrophobic or hydrophilic. Similarly, it is possible to select a material to construct the cleaning sheet that is selectively oleophobic or oleophilic. The following is a non-exclusive list of materials that may be used to construct the cleaning sheet: cellulosic fibrous web, polypropylene, polyethylene, and rayon webs.
- the cleaning sheet is constructed of an embossed web, between 1-30 mm in thickness, constructed of non-woven, random discontinuous blown microfibers and crimped macrofibers of polymeric materials according to U.S. Patent No. 4,118,531, entitled "Web of Blended Microfibers and Crimped Bulking Fibers".
- the fibers comprise a 60/40 blend of polypropylene/polyester.
- the cleaning sheet has a basis weight of 41.0 grams/meter sq. Such material is available from the Minnesota Mining and Manufacturing Company ("3M") of St. Paul, Minnesota under the trademark DoodledusterTM cloth.
- the cleaning sheet 140 includes a first cleaning surface 142 and an opposing second cleaning surface 144.
- the cleaning sheet is rectangular in shape and includes a longitudinally extending attachment edge 146 and a parallel trailing edge 148.
- a plurality of the cleaning sheets may be conveniently provided individually, stacked, or fan folded, most conveniently, the cleaning sheet is providing as part of a continuous strip in roll form 140a, as is also shown in Fig. 6.
- the cleaning sheet material may be severed from the free end of the roll in desired lengths, such as with a knife or scissors.
- the roll 140a may be constructed with a plurality of transverse weakened lines 149 at selected spaced locations.
- the weakened line may be formed such as by scoring the cleaning sheet material, in the preferred embodiment of the invention, the weakened line takes the form of a perforated line.
- the weakened lines 149 enable a segment of the cleaning sheet material to be manually separated from the roll.
- the weakened lines 149 may be located at desired regular intervals so that a single segment, or multiple segments may be separated as a unit (not shown) seriatim so that a single roll may be provided to supply cleaning sheet material to a variety of floor mops of different sizes. Although it may be possible to clean the cleaning sheet and reuse it, in the preferred embodiment of the invention, the cleaning sheet is discarded after use and replaced with a fresh, unused cleaning sheet in manner described in greater detail hereinafter.
- Means are provided to secure the flexible cleaning sheet to the leading edge of the mop head.
- a stiffening strip (not shown) may be attached to the attachment edge 146 of the cleaning sheet and the attachment edge inserted into and frictionally engaged with a slot (not shown) in the leading edge 110 of the mop head.
- the mop head may be constructed with plurality of projections, such as the "hook" portion of a hook and loop mechanical fastener system.
- the hooks or projections are used to engage and retain the cleaning sheet on the mop head.
- Such hooks are described in U.S. Patent No. 4,454,183, entitled “Strip Material With Heat Formed Hooked Heads".
- the mop head is constructed of pair of cooperative segments.
- the mop head segments take the form of first head portion 150a and second head portion 150b.
- Each mop head portion 150a, 150b includes outer surfaces 152a, 152b, facing inner surfaces 154a, 154b, a leading edge 156a, 156b, a trailing edge 158a, 158b, and respective opposing ends, 160a, 160b and 162a, 162b.
- the first mop head portion 150a and the second mop head portion 150b are shiftable with respect to each other between a first closed position, as shown in Figures 4 A and 4B, wherein the respective leading edges 156a, 156b are adjacent each other; and a second, open position, as shown in Figure 4C, wherein the leading edges 156a, 156b are spaced apart.
- a cleaning sheet 140 may be inserted in between the facing surfaces 154a, 154b so that when the mop head portions 150a, 150b are shifted to their closed position, the cleaning sheet is engaged with the mop head.
- first mop head portion and the second mop head portion are hingedly connected adjacent the respective trailing edges 158a, 158b thereof so as to rotate in opposite rotational directions 170a, 170b about longitudinal axis 172.
- the hinged connection may be constructed by providing a plurality of spaced arcuate sections 174 projecting from the trailing edge 158b of the second mop head portion 150b.
- the projections 174 each define an aligned cylindrical surface 176 having an inner diameter di.
- a plurality of like sized, solid arcuate projections 178 extend from the trailing edge 158a of the second mop head portion 150a. Extending longitudinally between the projections 178 along the trailing edge 158a of the first mop head portion 150a are hinge rods 180.
- the hinge rods 180 have an outer diameter d 2 .
- Diameter d 2 and diameter di defined by projections 174 are sized so as to form a sliding rotative fit when the hinge rods 180 are engaged with the cylindrical surfaces 176 by interdigitating the hinge rods with the projections 174 of the first mop head portion.
- This arrangement enables the first and second mop head portions to rotate relative to each other in opposing rotative directions 170a, 170b between the open and closed positions, as previously described.
- any other suitable hinge structure may be employed.
- the relative locations of the arcuate projections 174 and the hinge rods 180 may be reversed with respect to the first and second mop head portions, if desired.
- the illustrated embodiment facilitates the construction of the first mop head portion and the second mop head portion to be molded in unitary manner, preferably from a polymeric material.
- a polymeric material preferably from urethane, acrylonitrile butadiene styrene (ABS), polypropylene, and nylon.
- ABS acrylonitrile butadiene styrene
- nylon nylon
- the components of the floor mop, including the mop head and the cleaning sheet should be constructed from materials that are resistant to the environment and substances to which the floor mop is exposed during use.
- the molded first and second mop head portions may be preferably constructed with a reduced amount of material to reduce material expense, such as by including reinforcing ribs 182 on the facing surfaces 154a and 154b. Preferably, all corners or obstructions are avoided, such as at the intersection of the ribs, to facilitate cleaning of the mop head portions.
- a minimum weight for the mop head should be maintained in order to ensure the effective cleaning of the floor to which the floor mop is applied.
- the preferred weight of a mop head that is 26.5 inches x 4.0 inches is at least 600 grams and is most preferably approximately 660 grams.
- the facing surfaces 154a, 154b of the first and second mop head portions may be so constructed as to facilitate the securement of the cleaning sheet to the mop head when the first and second mop head portions are in their closed position. In the illustrated embodiment, this is accomplished by providing one or more prongs 191 projecting from at least one of the facing inner surfaces 154a, 154b (preferably projecting from surface 154b as shown in Figure 4C). The cleaning cloth 140 is engaged with the prongs and then secured by shifting the first and second mop head portions 150a, 150b to their closed position.
- a longitudinal channel 190 is formed in the inner surface 154a of the first mop head portion adjacent to the leading edge.
- a longitudinal ridge 192 projects from surface 154b of second mop head portion 150b and is aligned with channel 190 and extends into the channel when the first and second mop head portions are in their closed position. Ridge 192 contacts attachment edge 148 of the cleaning cloth 140 and forms a stop to locate the cleaning cloth with respect to the mop head. This arrangement controls the amount of the cleaning cloth that is used to secure the cleaning cloth to the mop head.
- Means are provided to clamp the first mop head portion 150a and the second mop head portion 150b together when they are in their closed position to secure the cleaning sheet 140 in engagement with the mop head.
- Any suitable clamping arrangement may be employed, such as magnetic latches (not shown), a spring (not shown) to resiliently bias the first mop head portion and the second mop head portion in their closed position, or a mechanical snap closure (not shown), or hook and loop type mechanical fasteners as have previously been discussed herein.
- latch means are provided to clamp the first and second mop head portions together in the closed position.
- a pair of spaced latch assemblies 200 are included.
- Each latch assembly includes a generally "L" shaped latch member 202 projecting from the inner surface 154b of the second mop head portion 150b.
- the segment 202a of the latch member extends towards the trailing edge 158b of the second mop head portion.
- the latch member 202 is constructed to be resiliently biased to an upright position, as shown, yet permits the latch member to be deflected in rotational direction 204, as will be explained in greater detail hereinafter.
- One or more tangs 206 project from the latch member 202 facing the leading edge 156b.
- a second tang 208 projects from inner surface 154a of the first mop head portion 150a.
- the second tang 208 is located adjacent opening 210 extending through the first mop head portion 150a.
- This rotational movement disengages the first and second tangs 206, 208, enabling the first and second mop head portions to be rotated to the open position. It is one of the features of the present inventions that the mop head may be opened to remove the cleaning sheet without contact with the cleaning sheet.
- Handle member 104 is adapted for manual engagement.
- One end 220 of the handle member is connected to the mop head 102.
- Any suitable arrangement may be provided to connect the handle member to the mop head.
- the handle member is pivotally connected to the mop head, to facilitate the manipulation of the mop head as hereinafter described.
- the handle member is pivotally connected to the mop head by a positional universal joint 228, such as is shown and described in U.S. Patent No. 3,850,533.
- An operator may place the handle and frame in a pre-selected position to effectively clean a given surface, and when he desires, readily manually reposition the frame and handle without loosening or tightening screws, bolts, or other type of fastener.
- the pivotal connection includes aligned holding members 230 projecting from inner facing surface of 154b second mop head portion 150b.
- the holding members are integrally molded with the second mop head portion.
- the holding members 230 each have axially aligned openings 232 therethrough. The openings are parallel to the longitudinal axis 122 of the mop head.
- the holding members could be located at any suitable location on the mop head, preferably, the openings 232 are centered at the midpoint of the mop head between the leading edges 156a, 156b and the trailing edges 158a, 158b; and midway between the first cleaning support 142 surface and the second cleaning support surface 144; as well as midway between the first ends 160a, 160b and the second ends 162a, 162b of the mop head. It is believed that this location most effectively facilitates the manipulation of the mop head and most efficiently applies the force applied to the mop head form the handle member to urge the cleaning sheet into contact with the surface to be cleaned.
- Connecting member 233 includes two aligned arms 234,236, each having a first bore 238 extending therethrough.
- a second bore 240 extends though the connecting member about an axis that is at right angles to the axis of bore 238.
- Handle holder 242 comprises arms 244, 246 having axially aligned circular openings 248, 250 therethrough.
- the upper end of handle holder 242 comprises socket 252 having internal threads 254 for attaching an externally complementarily threaded end 220 of the handle 104. If desired, threaded socket 252 can be replaced with any available type of handle member holding means.
- One of the bores is positioned between holding members 230, the other bore being positioned between openings 238,240 of arms 234,236.
- Holding members 230, connecting member 233, and handle holder 242 are securely attached to each other by means of plugs 260 which each include a head portion 262 and shank portion 264.
- Head 262 is slightly smaller in diameter than openings 238 and 240, and the diameter of shank 264 is about the same as the diameter of bores 238,240 to create a tight friction fit when shank 264 is inserted in bore.
- Shank 264 has annular ribs 266 to assist in securely retaining plugs 260 in bores 238,240 when shank 264 is inserted therein, and has groove 267 to permit escape of air when plug 260 is inserted in bore.
- Head portion 262 of plug 260 has annular groove 268 thereon to support a rubber friction ring such as O-ring 270.
- Rubber O-ring 270 has an inner circumference about the same as that seated therein, the thickness of O-ring 270 and the depth of groove 268 being such that part of O-ring 270 extends beyond head 262.
- O-ring 270 frictionally engages smooth inner walls 274 of bore 238 of connecting member 233 and smooth inner walls 276 of opening 238 in arms 234 and 236, the friction fit providing universal joint 228 with a freedom of movement which permits manual adjustment to various positions, the friction fit retaining the preselected position during use of the mop.
- their opposing ends may be adhered to each other or joined by other connecting means such as wires, suitable adhesives or the like.
- holding members 230, connecting member 233, and handle holder 242 are constructed of acrylonitrile- butadiene-styrene copolymer but may be of polyacetal, nylon, metal, etc.
- Plugs 260 are preferably constructed of glass fiber filled nylon or brass but may be of the same materials used for base holding members 230.
- O-rings 270 are preferably of a butadiene-acrylonitrile rubber copolymer having a durometer of about 70 to provide long life as well as good oil and water resistance.
- a cleaning sheet 140 is provided with the mop head 102 in its open position.
- the attachment edge of the cleaning sheet is inserted between the first and second mop head portions 150a, 150b, and the mop head portions are shifted to their closed position and clamped therein to secure the cleaning sheet to the mop head.
- a cleaning sheet may be employed with the present invention that is approximately 30-33% smaller than the corresponding cleaning sheet required under the DoodledusterTM system.
- the mop head 102 is then manipulated by the handle member 104 so as to present the cleaning support surface 118 to the floor.
- the cleaning sheet 140 extends from the leading edge 110 of the mop head, wherein it is attached to the mop head, towards the trailing edge 112.
- the cleaning sheet is constructed so that the free portion (that is the portion not secured to the mop head) covers the cleaning support surface 118 entirely and extends to the trailing edge 112.
- the mop may be manipulated in any desired manner to clean the floor by collecting any encountered particulates, liquids or both.
- the mop may be quickly and easily manipulated to invert the mop head (as sequentially shown in Figures 10A, 10B and IOC) so that the second cleaning support surface 144 is directed towards the floor. This process is also less time consuming then the process for reversing the dusting fabric attendant in the DoodledusterTM system, which requires opening and closing of the toggle assemblies, as previously described herein.
- the cleaning sheet is reversed so that the cleaning sheet extends from the leading edges 156a, 156b towards the trailing edges 158a, 158b over the second cleaning support surface 120 with the second cleaning surface 144 of the cleaning sheet presented to the floor. It will be understood that this process eliminates the need for the user of the floor mop to have any contact with the cleaning sheet.
- the cleaning of the floor may be resumed until the cleaning capacity of the second cleaning surface 144 of the cleaning sheet 140 is reached. At this point, the mop head is opened and the cleaning sheet removed with minimal, or preferably no, contact by the user and discarded.
- the first and second cleaning support surfaces 118 and 120 may be modified, if desired.
- a layer of a resilient material including, but not limited to, a foamed layer polyurethane, styrene butadiene polymer, neoprene, or acrylonitrile polymer, may be applied to the first and second cleaning support surfaces 118,120 to resiliently support the cleaning sheet 140 while applied to a floor.
- a layer of a resilient material including, but not limited to, a foamed layer polyurethane, styrene butadiene polymer, neoprene, or acrylonitrile polymer, may be applied to the first and second cleaning support surfaces 118,120 to resiliently support the cleaning sheet 140 while applied to a floor.
- the first and second cleaning support surfaces 118,120 may be adapted to frictionally grip the cleaning sheet.
- a fresh cleaning sheet may be inserted and secured to the mop head as previously described.
- the floor mop described herein may be utilized as part of a floor cleaning system in combination with an extended length of the cleaning sheet material.
- the extended length of the cleaning sheet material is provided in roll form.
- a suitable segment of the cleaning sheet material may be separated from the roll for use with the mop head.
- TEST FLOOR SELECTION An area 2 foot by 13 foot (61 cm x 396 cm) was delineated on the vinyl tile floor of a normally maintained commercial office building.
- FLOOR CLEANING PROTOCOL The area was cleaned prior to testing by vacuuming followed by wet mopping with water. The test area was allowed to air dry.
- TEST SOIL COMPOSITION A test soil composition was prepared by dry blending 24% by weight walnut sawdust (obtainable from Agrashell Company, Bath, PA); 11.5% pumice (Harcross Chemicals, Kansas City, KS ); 6% aluminum oxide, 60 - 80 mesh; 6% aluminum oxide, 100 - 150 mesh; 22.5% silica, 180 - 200 mesh (obtained from Ottawa Silica Company, Ottawa, LL); 23% Fuller's earth (obtained from Absorbent Clay Products, Monds, LL); and 7% yellow pigment (C.I.
- test soil was shaken reasonably uniformly along the center line down the length of the test area.
- FLOOR MOP ASSEMBLIES The test floor mop constructed according to Figures 3-1 IB herein, utilizing a cleaning sheet measuring 28 inches by 4.5 inches (71 cm x 11 cm) resulting in a surface area approximately 26 inches by 4 inches (66 cm x 10 cm) contacting the floor.
- the control dust mop a DoodledusterTM brand dust mop available from the Minnesota Mining and Manufacturing Company ("3M") of St. Paul, Minnesota, with a dusting cloth measuring 28 inches by 7.2 inches (18 cm x 71 cm) resulting in opposing cleaning surfaces of approximately 25 inches by 4.5 inches (63 cm x 11 cm) contacting the floor.
- CLEANING EFFICACY CYCLE A tared sample of dust cloth was attached to each of the floor mops as described above. Beginning at one end of the test area, the floor mops were pushed down the length of the test area in a straight line with the floor mops generally centered along the center line of the test area. Without lifting the floor mops from the floor, the assembly was turned around and pushed back to the starting point. In this manner, some portion of the test soil was captured by the dust cloth material. After having returned to the starting point, the dust cloth was removed from the floor mop. The cloth and entrapped soil were weighed. Subtracting the tare weight of the cloth from the final weight yielded the amount of soil captured by the floor mop and cloth assembly.
- TEST PROTOCOL For each floor mop tested, the cleaning cycle was repeated five times (one treatment group) and the results averaged. After each treatment group, the test area was cleaned according to the above floor cleaning protocol. In order to determine the most effective placement on the mop head of the attachment between the mop head and the handle member, during some cleaning cycles the handle member was held about waist high, at other times about shoulder high, and at yet other times in a position intermediate between waist and shoulder. These positions corresponded approximately to a handle-to-floor angle of about 30 degrees, 50 degrees and 40 degrees respectively.
