- a soft pad 56 is a closed cell EVA having a thickness of about 5 mm and a relatively soft Shore Durometer hardness property.

- the central trisection 36 may be hingedly joined to either or both of the outboard trisections 38 at the juncture between one or both of the outer edges 26 of the central trisection 36 and the inner edges 28 of the outboard trisection.
- Such hinged joining may be accomplished through a living hinge or other hinge mechanisms, as are well known in the art. This arrangement provides for articulation, and hence relative movement, between adjacent trisections 35 .
- the sections 35 may articulate from a position which provides one or more cavities between the cleaning surface 30 of the head 20 and the target surface when the sections 35 are in the first position.
- the sections 35 may be articulable to, and even past the coplanar second position. Referring to FIGS. 4-5 , upon the application of force having a Z-direction component through the attachment 50 , the central trisection 36 and outboard trisections 38 move relative to each other from the first position having a noncoplanar cleaning surface 30 to a second position having a generally coplanar cleaning surface 30 .
- the head 20 may be augmented with a platen 46 disposed intermediate the attachment 50 and the central trisection 36 .
- the platen 46 may receive the compressive force applied through the attachment 50 and be displaced in the Z-direction in response.
- the platen 46 has a peripheral region which is aligned with a portion of the outboard trisections 38 .
- the platen 46 may be joined to the outboard trisections 38 , in order to transmit force thereto, as applied through the attachment 50 .
- connection between the platen 46 and the outboard trisections 38 may be accomplished through rails 48 , which allow the peripheral portions of the platen 46 and the outboard trisections 38 to slidably move relative to one another.
- a T-section railing 48 is illustrated in FIGS. 3 and 5 , although one of skill will realize that complementary railings 48 are not so limited.
- the platen 46 may also disposed directly above the central trisection 36 , and collinear with the Z-axis and center of the cleaning surface 30 . This arrangement allows a portion of the force transmitted through the attachment 50 to be applied to the central trisection 36 . As the platen 46 becomes larger in the XY plane, it will generally distribute pressure laterally further from the attachment 50 or other point where the force is applied by the user.
- the head 20 may further optionally comprise a return mechanism 40 to assist in returning the configurations of the trisections 35 from the first position to the second position.

- the return mechanism 40 may comprise rails 48 , as described above. All of these return mechanisms 40 , as well as others, are known in the art.
- One suitable return mechanism 40 is a biasing spring to cause the head 20 to automatically return from the second position, being generally coplanar to the first position, which the head 20 inherently assumes without the application of external force through the attachment 50 .
- the return mechanism 40 may be any member, as is well known in the art, which causes relative movement between the central trisection 36 and outboard trisection, in order to become non-coplanar from a coplanar configuration.
- the return mechanism 40 may be a biasing spring.
- the biasing spring may be a compression spring as is known in the art. Suitable compression springs include a flat spring or a coil spring. The spring may be disposed between the upwardly facing surface and the platen 46 . A rim may circumscribe the coil spring to minimize lateral mispositioning or lateral movement during use.
- the biasing spring should not impart undue resistance to the user when force is applied to the head 20 throughout the handle and attachment 50 . Of course, the resisting force of the biasing spring may be taken into account when considering the amount of force necessary to move the three trisections 35 to a generally coplanar configuration. Likewise the weight of the handle, if significant, may be considered as adding to the applied compressive force.
- Such movement may occur due to the application of compressive forces through the handle, to the attachment 50 .
- Such compressive forces may have a vector component in the Z-direction to effect the aforementioned articulation.
- the force applied to the head 20 may be applied in the Z-direction. If the handle is disposed perpendicular to the target surface, the Z-direction will be coincident the longitudinal axis of the handle.
- the amount of force applied in the Z-direction may be at least about 0.4, 0.5 or 0.8 kg, but less than about 7, 8 or 9 kg. If the head 20 is to be used with a handle of appropriate length for a standing user to clean a floor, and dry cleaning/dusting is desired, the amount of applied force to cause the head 20 to become co-planar and assume the first position may be at least about 4 kg, but not more than about 8 kg. This force level is judged to be sufficient to allow the cavities to remain open in normal use and usable to collect large particles at the end of the cleaning cycle.
- the amount of applied force to cause the head 20 to become co-planar and assume the first position may be at least about 0.4 kg, but not more than about 4 kg.
- the head 20 may comprise two sections 35 movable relative to one another and disposed on the cleaning surface 30 .
- One section 35 such as a first section 35 may be stationary as disposed on a target surface and the other section 35 , such as a second section 35 movable relative thereto.
- the head 20 may be generally rectangular, having four sides with two different lengths. If so, the movable section 35 may be disposed on a side, such as the longer side, of the head 20 . In a degenerate case, this embodiment may be thought of as similar to that shown in FIGS. 1-5 , with a single movable trisection 35 .
- the section 35 which has primary contact with the target surface may be considered the first section 35 and the second which is disposed in angular relation relative to the target surface may be considered the second section 35 .
- the second section 35 may be movable relative to the first section 35 .
- the second section 35 may have a width of at least about 10 percent or about 25 percent, but not more than about 50 percent of the total width of the head 20 . This width, for a suitable length is judged to provide pickup for large particles collected by the head 20 at the end of the cleaning cycle.
- This arrangement provides the benefit that the user may clean the target surface with a cleaning device having a head 20 according to the present invention and then position the second section 35 of the cleaning surface 30 above loose particles collected on the target surface. The user may then apply compressive force through the handle, causing the second section 35 to articulate, become generally coplanar with the first section 35 and pick up loose particles and other dirt.
- the head 20 may comprise two sections 35 , with a first section 35 being disposed external to and circumscribing or substantially circumscribing a second section.
- the second section 35 may be congruent with the perimeter of the head 20 , or may be of any other suitable geometry.
- the second section 35 may have a surface area of at least about 25 percent, 50 percent or 75 percent of the total surface area of the head 20 .
- the surface area and geometry described above are taken at the cleaning surface 30 of the head 20 .
- This arrangement provides the benefit that the user may clean the target surface with a cleaning device having a head 20 according to the present invention and then position the second section 35 of the cleaning surface 30 above loose particles collected on the target surface. The user may then apply compressive force through the handle, causing the second section 35 to articulate, become generally coplanar with the first section 35 and pick up loose particles and other dirt. The dirt may be circumscribed by the first section 35 , and be less likely to not be picked up by the head 20 .
- the heads 20 may be described as follows:
- Head 1 is a SwifferTM Sweeper head, currently sold by the instant assignee.
- Head 3 is a head 20 according to the present invention and having a central trisection 36 and two outboard trisections 38 in the cleaning surface 30 and a bottom pad 56 with slits between the trisections 35 .
- Head 4 is a head 20 according to the present invention without cavities in the cleaning surface 30 and a solid bottom pad 56 without slits between the trisections 35 .
- Each head 20 had a closed cell EVA bottom pad 56 , with small protuberances, as commercially sold on Head 1.
- Each head 20 was placed on a pressure pad having sensors with an approximately one mm XY resolution, statically loaded as described above, and measured for the resulting stress distribution over an Effective Area, Average Pressure throughout the area, and Peak Pressure (generally coincident the Z-axis). The results are shown in Table 1 below.
Abstract
A head for a cleaning device. The head has a cleaning surface which has multiple sections. The sections are movable relative to each other in response to force applied by the user. The sections can be moved from a first configuration having noncoplanar sections to a second configuration where the sections are coplanar. The noncoplanar configuration may provide cavities for the collection of debris from a surface to be cleaned, such as a floor. The coplanar configuration may provide for improved stress distribution across the cleaning surface.
Description
- The present invention relates to a head for a cleaning device, and more particularly for a cleaning device usable for hard surfaces, such as floors.
- Cleaning devices for hard surfaces, such as floors are well known in the art. One such device is the Swiffer™ Sweeper, sold by the instant assignee. Hard surfaces include vinyl flooring, hardwood, tile, stone, and other target surfaces, to be cleaned.
- Such cleaning devices typically have a flat unitary head, to which a disposable cleaning cloth may be attached. Considerable effort has been paid to improving such cleaning cloths, in order to increase the amount of dirt picked up during use. However, relatively few attempts have been made to improve cleaning by modifying the head.
- Two attempts in the art by the instant assignee include US 2006/0016037 A1 published in the names of Flora et al. and U.S. Pat. No. 6,842,936 B2 issued to Policicchio et al. Another attempt in the art is found in U.S. Pat. No. 7,264,413 B2 issued to Vosbikian et al. Vosbikian et al. shows a mop head having a pair of opposing plates rotatable about a pivot axis. However, this attempt fails to produce a continuous width mop head which relatively uniformly distributes applied pressure.
- If pressure is not relatively uniformly applied, the effective cleaning area of the head of the mop may be decreased. As the effective cleaning area is decreased, the amount of dirt picked up during use may likewise decrease.
- Accordingly, a head for a cleaning device which increases the effective surface area over prior art attempts; and which provides more uniform pressure throughout would likely provide improved cleaning performance.
- The invention comprises a head for a cleaning device usable for cleaning a surface. The head comprises at least two sections, at least a first section and second section. At least one of the sections is movable relative to the other, whereby compressive force applied to the head causes the sections to become substantially coplanar. The head may comprise an optional return mechanism to return one of sections to a non-coplanar configuration upon removal of the compressive force; and an optional attachment for receiving a handle. A handle may be connected to one or more of the sections through the attachment.

The X and Y dimensions refer to the length and width of the
head 20, respectively. The Z direction is perpendicular to the XY plane and may be centered on theattachment 50 to thehead 20. Upper refers to a position or direction relatively further from the target surface, while lower refers to a position or direction relatively closer to the target surface. Thehead 20 may have a leadingedge 22 andtrailing edge 24, which are the edges facing the direction of movement on the forward stroke and backward stroke by a user, respectively. Compressive force refers to a force applied coincident the Z-axis when thehead 20 is disposed on a target surface parallel the XY plane. Coplanar refers to a configuration of a surface being generally flat in two dimensions, with allowance being made for normal variations and deviations from true planarity. - Referring to
FIG. 1 , thehead 20 according to the present invention may be generally rectangularly shaped, or shaped in any other suitable geometry, such as having a point to reach into corners. Thehead 20 has mutually orthogonal length and width dimensions, lying in the XY plane and a thickness taken in the Z-direction. - The
head 20 may have two generally opposed major surfaces, acleaning surface 30 facing downward towards the target surface to be cleaned, and an upwardly facingtop surface 32. Thetop surface 32 andcleaning surface 30 may be formed from two independent components. Thecleaning surface 30 may be generally contiguous and generally planar throughout, when subjected to compressive forces by a user. - The
head 20 my have two, three ormore sections 35, with one ormore sections 35 being movable relative to the other. Thesections 35 may intercept thecleaning surface 30. Thesections 35 may be movable relative to each other from a first position to a second position through articulation, translation, etc. In the first position, thecleaning surface 30 is not co-planar. In the non-coplanar configuration, thecleaning surface 30 may have a cavity for receiving dirt to be cleaned from the target surface. In the second position thecleaning surface 30 may be generally co-planar and continuous across allsections 35. - A
return mechanism 40 may be employed to return thesections 35 of thehead 20 from the first position to the second. Thereturn mechanism 40 may be disposed so that it does not intercept thecleaning surface 30. Thehead 20 may also have anattachment 50 for connecting a handle, in order to provide convenience for the user. However, it is to be recognized thehead 20 according to the present invention may be used without a handle, as for example, occurs with a scrub brush. - The
attachment 50 may comprise a universal joint, as shown or a different Cardan joint. Theattachment 50 may alternatively comprise a ball and socket joint, etc. as are known in the art. - The
head 20 may have one ormore grippers 42, to removable attach a cleaning cloth.Suitable grippers 42 may be made according to commonly assigned U.S. Pat. No. 6,651,290 B2. Suitable cloths may be made according to commonly assigned U.S. Pat. Nos. 6,936,330 B2 and/or D 489,537. - The cleaning
surface 30 may be covered with asoft pad 56 to provide resiliency to account for for asperities in the target surface. Onesuitable pad 56 is a closed cell EVA having a thickness of about 5 mm and a relatively soft Shore Durometer hardness property. Thepad 56 may be slit, to provide hinge lines coincident the hinge lines between adjacent junctures between thetrisections 35. This allows for greater freedom of relative movement between thetrisections 35. For clarity thepad 56 is not shown inFIG. 2 , 4, 6 or 7. - Referring to
FIGS. 2-3 and examining thehead 20 in more detail, in one embodiment thehead 20 may have threetrisections 35, acentral trisection 36 flanked by twooutboard trisections 38. Thehead 20 may be symmetric about an axis parallel to the x direction, y direction or both. Thecentral trisection 36 may have twoouter edges 26 facing and juxtaposed with two correspondinginner edges 28 of theoutboard trisections 38. Likewise, theoutboard trisections 38 may have twoouter edges 26 facing the leading and trailingedges head 20, or facing the sides of thehead 20. Theoutboard trisections 38 may have a length less than that of the central trisection 36 (as shown), or a length greater than or equal to that of thecentral trisection 36. - If desired the
central trisection 36 may be hingedly joined to either or both of theoutboard trisections 38 at the juncture between one or both of theouter edges 26 of thecentral trisection 36 and theinner edges 28 of the outboard trisection. Such hinged joining may be accomplished through a living hinge or other hinge mechanisms, as are well known in the art. This arrangement provides for articulation, and hence relative movement, betweenadjacent trisections 35. - The
sections 35 may articulate from a position which provides one or more cavities between the cleaningsurface 30 of thehead 20 and the target surface when thesections 35 are in the first position. Thesections 35 may be articulable to, and even past the coplanar second position. Referring toFIGS. 4-5 , upon the application of force having a Z-direction component through theattachment 50, thecentral trisection 36 andoutboard trisections 38 move relative to each other from the first position having anoncoplanar cleaning surface 30 to a second position having a generallycoplanar cleaning surface 30. - If desired, a more elaborate mechanism may be utilized to join the
central trisection 36 andoutboard trisections 38. For example, thehead 20 may be augmented with aplaten 46 disposed intermediate theattachment 50 and thecentral trisection 36. Theplaten 46 may receive the compressive force applied through theattachment 50 and be displaced in the Z-direction in response. Theplaten 46 has a peripheral region which is aligned with a portion of theoutboard trisections 38. Theplaten 46 may be joined to theoutboard trisections 38, in order to transmit force thereto, as applied through theattachment 50. - The connection between the
platen 46 and theoutboard trisections 38 may be accomplished throughrails 48, which allow the peripheral portions of theplaten 46 and theoutboard trisections 38 to slidably move relative to one another. A T-section railing 48 is illustrated inFIGS. 3 and 5 , although one of skill will realize thatcomplementary railings 48 are not so limited. - The
platen 46 may also disposed directly above thecentral trisection 36, and collinear with the Z-axis and center of the cleaningsurface 30. This arrangement allows a portion of the force transmitted through theattachment 50 to be applied to thecentral trisection 36. As theplaten 46 becomes larger in the XY plane, it will generally distribute pressure laterally further from theattachment 50 or other point where the force is applied by the user. - The
head 20 may further optionally comprise areturn mechanism 40 to assist in returning the configurations of thetrisections 35 from the first position to the second position. Thereturn mechanism 40 may comprise a cam, which locks into place at each of the first and second positions. Alternatively, thereturn mechanism 40 may comprise tension springs joining theoutboard trisections 38 in the width direction of thehead 20. Alternatively thereturn mechanism 40 may comprise a bistable hinge joining the outboard trisections 38 andcentral trisection 36. Alternatively thereturn mechanism 40 may comprise a ball and socket connection between outboard trisections 38 andplaten 46. Alternatively, thereturn mechanism 40 may compriserails 48, as described above. All of thesereturn mechanisms 40, as well as others, are known in the art. - One
suitable return mechanism 40 is a biasing spring to cause thehead 20 to automatically return from the second position, being generally coplanar to the first position, which thehead 20 inherently assumes without the application of external force through theattachment 50. Thereturn mechanism 40 may be any member, as is well known in the art, which causes relative movement between thecentral trisection 36 and outboard trisection, in order to become non-coplanar from a coplanar configuration. - In one embodiment the
return mechanism 40 may be a biasing spring. The biasing spring may be a compression spring as is known in the art. Suitable compression springs include a flat spring or a coil spring. The spring may be disposed between the upwardly facing surface and theplaten 46. A rim may circumscribe the coil spring to minimize lateral mispositioning or lateral movement during use. The biasing spring should not impart undue resistance to the user when force is applied to thehead 20 throughout the handle andattachment 50. Of course, the resisting force of the biasing spring may be taken into account when considering the amount of force necessary to move the threetrisections 35 to a generally coplanar configuration. Likewise the weight of the handle, if significant, may be considered as adding to the applied compressive force. - Referring to
FIGS. 4-5 , upon moving thecentral trisection 36 in the Z-direction and constraining the one or both of the outer edges of theoutboard trisections 38 from movement in the Z-direction, relative movement between thecentral trisection 36 and respectiveoutboard trisections 38 will occur. Such relative movement occurs as articulation between the articulably joined edges ofadjacent trisections 35. - Such movement may occur due to the application of compressive forces through the handle, to the
attachment 50. Such compressive forces may have a vector component in the Z-direction to effect the aforementioned articulation. - The force applied to the
head 20 may be applied in the Z-direction. If the handle is disposed perpendicular to the target surface, the Z-direction will be coincident the longitudinal axis of the handle. - The amount of force applied in the Z-direction may be at least about 0.4, 0.5 or 0.8 kg, but less than about 7, 8 or 9 kg. If the
head 20 is to be used with a handle of appropriate length for a standing user to clean a floor, and dry cleaning/dusting is desired, the amount of applied force to cause thehead 20 to become co-planar and assume the first position may be at least about 4 kg, but not more than about 8 kg. This force level is judged to be sufficient to allow the cavities to remain open in normal use and usable to collect large particles at the end of the cleaning cycle. If thehead 20 is to be used with a handle of appropriate length for a standing user to clean a floor, and wet cleaning/moping is desired, the amount of applied force to cause thehead 20 to become co-planar and assume the first position may be at least about 0.4 kg, but not more than about 4 kg. - Referring to
FIG. 6 , thehead 20 may comprise twosections 35 movable relative to one another and disposed on thecleaning surface 30. Onesection 35, such as afirst section 35 may be stationary as disposed on a target surface and theother section 35, such as asecond section 35 movable relative thereto. Thehead 20 may be generally rectangular, having four sides with two different lengths. If so, themovable section 35 may be disposed on a side, such as the longer side, of thehead 20. In a degenerate case, this embodiment may be thought of as similar to that shown inFIGS. 1-5 , with a singlemovable trisection 35. - In such a configuration, the
section 35 which has primary contact with the target surface may be considered thefirst section 35 and the second which is disposed in angular relation relative to the target surface may be considered thesecond section 35. Thesecond section 35 may be movable relative to thefirst section 35. Thesecond section 35 may have a width of at least about 10 percent or about 25 percent, but not more than about 50 percent of the total width of thehead 20. This width, for a suitable length is judged to provide pickup for large particles collected by thehead 20 at the end of the cleaning cycle. - This arrangement provides the benefit that the user may clean the target surface with a cleaning device having a
head 20 according to the present invention and then position thesecond section 35 of the cleaningsurface 30 above loose particles collected on the target surface. The user may then apply compressive force through the handle, causing thesecond section 35 to articulate, become generally coplanar with thefirst section 35 and pick up loose particles and other dirt. - Referring to
FIG. 7 , in another embodiment, thehead 20 may comprise twosections 35, with afirst section 35 being disposed external to and circumscribing or substantially circumscribing a second section. Thesecond section 35 may be congruent with the perimeter of thehead 20, or may be of any other suitable geometry. Thesecond section 35 may have a surface area of at least about 25 percent, 50 percent or 75 percent of the total surface area of thehead 20. Of course, the surface area and geometry described above are taken at the cleaningsurface 30 of thehead 20. - This arrangement provides the benefit that the user may clean the target surface with a cleaning device having a
head 20 according to the present invention and then position thesecond section 35 of the cleaningsurface 30 above loose particles collected on the target surface. The user may then apply compressive force through the handle, causing thesecond section 35 to articulate, become generally coplanar with thefirst section 35 and pick up loose particles and other dirt. The dirt may be circumscribed by thefirst section 35, and be less likely to not be picked up by thehead 20. - Referring to
FIGS. 8A-8D , fourheads 20 of exemplary cleaning devices were tested under uniform loading conditions to evaluate the XY stress distribution. Theheads 20 may be described as follows: -
Head 1 is a Swiffer™ Sweeper head, currently sold by the instant assignee. - Head 2 is a
head 20 having threetrisections 35 locked into a coplanar configuration with shims and aplaten 46. - Head 3 is a
head 20 according to the present invention and having acentral trisection 36 and twooutboard trisections 38 in thecleaning surface 30 and abottom pad 56 with slits between thetrisections 35. - Head 4 is a
head 20 according to the present invention without cavities in thecleaning surface 30 and a solidbottom pad 56 without slits between thetrisections 35. - Each
head 20 had a Z-direction force of approximately 23.1 kg applied through a handle having a length of about 18 cm and aplaten 46 having a width of about 4 cm in each direction from the Z-axis.Head 1 did not have areturn mechanism 40. Heads 2-4 had a coilspring return mechanism 40 which exhibited a counter-force of approximately 420 grams when thetrisections 35 were compressed to a generally coplanar configuration. This counter-force was not considered in the analysis below. - Each
head 20 had a closed cellEVA bottom pad 56, with small protuberances, as commercially sold onHead 1. Eachhead 20 was placed on a pressure pad having sensors with an approximately one mm XY resolution, statically loaded as described above, and measured for the resulting stress distribution over an Effective Area, Average Pressure throughout the area, and Peak Pressure (generally coincident the Z-axis). The results are shown in Table 1 below. -
TABLE 1 Average Pressure Peak Pressure Head Effective Area (cm2) (ksm) (ksm) 1 (prior art) 232 457 2720 2 243 598 2720 3 241 654 2720 4 264 710 2720 - Table 1 shows that the embodiments having three
trisections 35 as illustrated inFIGS. 1-5 , have a greater effective area and greater average pressure throughout such area than the prior art. Such increased surface area and average pressure throughout would be expected to result in greater dirt pickup during use.
