Definitions

  • the invention is related to the art of cleaning tools.
  • the invention will be described in terms of a household cleaning tool, such as, for example, a kitchen or bathroom cleaning tool.
  • a household cleaning tool such as, for example, a kitchen or bathroom cleaning tool.
  • the invention can be applied to other cleaning, polishing, sanding or similar applications.
  • Known battery powered cleaning tools suffer from at least one of the following three drawbacks. They require non-standard power sources or batteries that are not readily available; they include slide-type switches, which are not momentary in nature; and/or they apply torque, and, therefore, stresses, to cleaning heads or brushes at relatively narrow portions of cleaning attachments.
  • U.S. Patent No. 5,870,790 to Root, et al. discloses several battery powered scrubbing devices. Each disclosed scrubbing device includes a single rechargeable battery. Root does not disclose the size or type of battery. However, the relative size and shape of the battery shown in the illustrations, as well as a probable power requirement of a scrubbing device, indicate that the battery contemplated by Root is of a type not readily available to the general public.
  • Rechargeable batteries have a limited lifetime. Additionally, rechargeable batteries are known to have preferred operating and care conditions. For example, the useful lifetime of some rechargeable batteries is diminished if the batteries are not fully discharged before recharging. Many users of battery powered cleaning tools are unaware of, or are unwilling to devote the required attention to, a rechargeable battery care regime. Therefore, the difficulty in replacing the rechargeable batteries of Root, due to their uncommon nature, may lead to a shortened useful lifetime of the overall device.
  • the scrubbing devices of Root also include switches. Root does not disclose the type of switch. However, it appears that the switches disclosed in Root are of the push on/push off or slide type. For example, one switch is disposed at a back end of a scrubbing device.
  • Non-momentary switches can be problematic in cleaning tools because a distracted user can forget to shut the tool off before placing it, for example, on a counter top. For instance, a user may be distracted, by a telephone or a child, and place a cleaning tool with a spinning cleaning head on a counter top. In that case, the cleaning tool may run across the counter top possibly knocking glasses and dishes to the floor. If, on the other hand, a cleaning tool were to incorporate a momentary switch, the cleaning head would stop moving as soon as the tool was released. Furthermore, the inclusion of a momentary actuation switch in a cleaning tool helps conserve energy.
  • Root discloses several cleaning heads.
  • the cleaning heads include relatively narrow hexagonally shaped jacks that are received in a hexagonally shaped socket of the cleaning tool main body. Therefore, when the tool is operated, torque is applied with a very short moment arm to the edges and surfaces of the hexagonally shaped jack. Because the torque is applied with a relatively short moment arm, a working cleaning head, such as disclosed by Root, undergoes undue mechanical stresses that can lead to premature aging and, eventually, fatigue and brush failure.
  • U.S. Patent No. 6,295,681 Bl to Dolah discloses a rotary brush cleaning device including a rechargeable battery enclosed in a power source case, a switch of undisclosed type that appears to be a slide switch, and a plurality of cleaning heads. While Dolah suggests that replaceable batteries may be used, Dolah does not suggest a replaceable battery arrangement that would be adequate to provide the required power, nor does Dolah suggest a brush design that could accommodate replaceable batteries while maintaining an ergonomic form factor and pleasing design.
  • the brushes disclosed by Dolah include base portions that are used to connect the brushes to the main body of the cleaning device.
  • the base portions include L-shaped slots for receiving pins of the cleaning device.
  • the base portions of Dolah might be of a larger diameter than the jacks of Root. Therefore, Dolah may deliver torque to the brushes with a slightly larger moment arm.
  • the brushes of Dolah include relatively narrow elongated intermediate shafts. The relatively narrow elongated intermediate shafts can undergo undue stress concentration which may lead to premature failure.
  • U.S. Patent No. 4,137,588 to Sandt, et al. discloses a portable cleaning device. Like Root and Dolah, Sandt discloses a cleaning device having a switch of undisclosed type. However, the switch appears to be a non-momentary slide type.
  • the portable cleaning device includes a rechargeable battery of undisclosed size and type. However, the size and shape of the battery shown in the figures appear to be that of a battery that is not readily available to the general public.
  • the brushes of Sandt appear to receive torque in a manner similar to the brushes of Dolah.
  • the brushes of Sandt receive torque at a slightly larger moment arm than do the hexagonal jacks of Root.
  • the brushes of Sandt include relatively narrow shafts where damaging stress due to torque can be concentrated.
  • a first embodiment of a cleaning system includes a power compartment including, a power source housed within the power compartment, a motor mounted within the power compartment, the motor powered by the power source, a switch for selectively connecting the motor to the power source, and, a power output driven by the motor for delivering power to a device connected to the power compartment, a transmission module selectively connectable to the power compartment; and a cleaning head selectively connectable to the transmission module

  • the housing can be divided into sections.
  • the housing 102 includes a lower housing or power compartment 106 and an upper housing or transmission module 108.
  • the lower housing 106 and the upper housing 108 include threads 110, 112, respectively.

  • the power compartment can be sized to accommodate AAA, AA, C, D or 9V batteries. Both disposable and rechargeable batteries are available in these sizes. Additionally, chargers for these size rechargeable batteries are also readily available.
  • the exemplary lower housing or power compartment 106 is sized to accommodate four AA size batteries. Sizing the power compartment to accommodate four AA size batteries 114 allows the lower housing or power compartment to include an ergonomic gripping portion 116 while providing a six-volt power source with a 3,000 milliamp-hour (mA-hr) capacity (assuming commonly available alkaline-manganese dioxide cells are used).
  • mA-hr milliamp-hour
  • Other power sources may be selected. However, selecting other power sources may require a reduction in the ergonomic features of the cleaning tool 100 in general and the gripping portion 116 in particular. For example, accommodating C-type or D-type batteries may require the gripping portion 116 to be wider. Additionally, accommodating the larger cells (C type, D type) might require a more complicated construction. If, for example, the power source included two C-type batteries, it might be necessary to run a wire from a contact at a bottom end 118 to a first motor terminal 120. [0039] In an embodiment sized to accommodate four AA batteries, a spring contact plate 122 located at the bottom end 118 of the housing 102 is held in place by a spring contact cover 123.

  • An o-ring 203 seals the peripheral gear housing 154 against an inner wall of the upper housing or transmission module 108.
  • the button 146 performs a sealing function.
  • the button 146 may have additional sealing components associated therewith. If the housing 102 includes a plurality of sections, such as, for example, lower housing or power compartment 106 and upper housing or transmission module 108, a sealing component, such as a gasket 206, should be included therebetween. Where the housing 102 includes a removable battery door 208 for gaining access to a power source or batteries 114, a sealing element, such as an o-ring 210, should be included thereon.
  • a wide variety of work heads such as cleaning head 104
  • the cleaning head 104 can be a pot scrubber 404, a glass washer 410, a bottle washer 420, or a general-purpose brush 430.
  • Each work head includes elements directed toward a particular task.
  • pot scrubber 404 includes relatively short, stiff and abrasive bristles 440. It is anticipated that pot scrubbing may be a most demanding application of the cleaning system 100.
  • pot scrubbing may require that the pot scrubbing head 404 be pressed firmly against the work piece such as, for example, a cooking pot having food particles tenaciously adhered thereto, with a relatively high level of force. Therefore, in order to minimize cleaning head deflection, the pot scrubbing head 404 includes a relatively short stout body 444.
  • Other work pieces such as, for example, drinking glasses, are less likely to require the high level of cleaning effort associated with pots. Nevertheless, glassware provides its own set of cleaning challenges. For example, cleaning glasses can include long throats which make the recessed portions difficult to reach.
  • the glass washer 410 includes a long, narrow body 448 and somewhat softer bristles 452 as compared to the relatively stiff bristles 440 of the pot scrubber.
  • the long body 448 and relatively soft, bendable bristles 452 allow the glass washer 410 to reach and clean portions of a work piece that may be inaccessible to other work heads.
  • the bottle washer 420 includes features that make it preferable for cleaning bottles, such as, for example, baby bottles. Cleaning an individual baby bottle is not likely to be a particularly difficult task. However, where there is one baby bottle, there is likely to be a large number of other baby bottles. Therefore, a useful bottle washer quickly makes contact with all portions of the inner surface of a baby bottle in order to wipe away any residual, dried on milk or baby formula.
  • the bottle washer 420 includes a large number of individual brash filaments 464 distributed along a flexible wire shaft 468 and at a distal end 470 of the shaft.
  • the wire shaft 468 is longer than a typical baby bottle.
  • the brush filaments 464 are distributed along a portion of the shaft that is about at least as long as the depth of a typical baby bottle.
  • the brush filaments 464 can be relatively soft and be directed more toward wiping than scraping.
  • the bottle washer 420 includes short, stout connector portion 472 for connecting the wire shaft 468 to the hub 170.
  • the general purpose cleaning head 430 is of an intermediate length and may combine features of the pot scrubber 404 and, for example, the glass cleaner 410. For example, it can include the relatively stiff bristles of the pot scrubber 404 and the somewhat softer bristles 452 of the glass cleaner 410.
  • a body portion 484 of the general purpose cleaning head 430 can be somewhat longer than the short, stout body 444 of the pot scrubber 404.
  • work heads such as, for example, the cleaning heads 104, 404, 410, 420 and 430 share certain features in common.
  • all the work heads include a connector section 610.
  • the connector section 610 includes a socket element 164 centered on a longitudinal axis 168 of the cleaning head.
  • the socket includes a beveled leading edge 622 and a beveled trailing edge 624.
  • the connector section 610 includes a ring of torque-receiving teeth 630. The ring of torque-receiving teeth is concentric with the socket 614 about the longitudinal axis 618 of the cleaning head.
  • the socket element 614 is recessed into the cleaning head relative to the ring of torque-receiving teeth 630.
  • torque-receiving teeth 630 There are, for example, eight torque- receiving teeth in the ring, hi some embodiments there are only 4 torque receiving teeth.
  • Between adjacent torque-receiving teeth is an interdental space 634.
  • interdental spaces 634 there are eight interdental spaces 634.
  • the torque-receiving teeth 630 extend from a ring base 638.
  • the connecting hub 170 includes a collar 174 that is fitted over an output portion 160 of transmission output shaft 158. Pin 168 secures the collar 174 and, therefore, the hub 170, to the transmission output shaft 158.
  • the hub 170 also includes, for example, four torque transmission arms 644.
  • the swaging cams 202 of the distal end of the transmission output shaft 204 contact the leading beveled edge 622 of the socket 614.
  • the swaging cams 202 are deflected inwardly toward the longitudinal axis 618 of the working head.
  • the swaging cams slide over the beveled trailing edge 624 of the socket expanding outward away from the longitudinal axis 618, firmly engaging an interior shoulder 650 of the socket 614, thereby pulling the working head toward the hub 170 and securing the head as part of the cleaning system 100.
  • the torque delivery arms 644 are received within at least some of the interdental spaces 634. If an initial misalignment does not permit the torque-delivering arms 644 to be received within interdental spaces 634, then the working head can be twisted slightly until the torque transmission arms 644 and the interdental spaces 638 are properly aligned.
  • the hub 170 is also driven into rotation by the pin 168 comiecting the hub 170 to the transmission output shaft 158. Therefore, the torque delivering arms 644 are also driven to rotate.
  • the torque-delivering arms 644 are driven against respective teeth of the torque-receiving ring 630, and the working head is driven to rotate.
  • the ring of torque-receiving teeth 630 is spaced radially away from the longitudinal axis 618 of the working head. For example, an outer diameter of the ring of torque-receiving teeth 630 can be about 1 inch.
  • the torque transmitting arms 644 extend away from the longitudinal axis 648 of the cleaning system 100.
  • the torque transmitting arms 644 extend from the hub 174 to an inner wall 652 of the hub 170.
  • the inner wall 652 and, therefore, a distal end 656 of the torque-delivering arms is at a radius of about J inch from a longitudinal axis 648 of the cleaning system 100.
  • Torque-receiving teeth of the ring 630 are engaged by the torque transmission or delivery arms 644 at the distal end 656 of the arms 644.
  • the resulting moment arms provide for the delivery of torque to the work head at a reduced level of stress on the torque-receiving elements of the work head as compared to the level of stress delivered in prior art devices.
  • an increased radius of connecting elements such as the hub 170 and the connector section 610 of the work head allow additional material to be used in their manufacture, thereby increasing an overall ruggedness of the cleaning system 100 while maintaining an ergonomic design.
  • the housing 102 has a generally cylindrical shape. However, portions are tapered away from the cylindrical to provide an ergonomically comfortable design. For example, a portion of the housing 102 is tapered to provide the ergonomic gripping portion 116.
  • the gripping portion 116 can have a rounded rectangular cross section.
  • Gripping portion 116 has a length 710 at least long enough to allow it to fit comfortably in a hand 714 of an intended user. For instance, the length 710 is between about 3 inches and about 5 inches. In one embodiment, the length 710 is about 3.5 inches. This length provides enough room for four gripping fingers 718 of the hand 714 of the intended user to fit comfortably within the gripping portion 116 while allowing a compact and comfortable overall length for the housing 102.
  • a width 722 and a height 726 of the gripping portion are selected to allow the gripping portion 616 to fit comfortably within a palm 730 of the hand 714 of the intended user and allow the four gripping fingers 718 to wrap comfortably and securely around the gripping portion.
  • the length 710, width 722 and height 726 of the gripping portion 116 are selected to allow an internal portion or chamber within the gripping portion 116 to accommodate a power source, such as, for example, four commonly available AA size batteries 114.
  • the width 722 of the gripping portion is about one inch in width.
  • the width of the gripping portion 116 is tapered.
  • the width of that gripping portion 116 varies from about 0.98 inches to about 1.1 inches.
  • the height 726 of the gripping portion is about 1.4 inches.
  • the height of the gripping portion 116 is tapered.
  • the height of that gripping portion 116 varies from about 1.34 inches to about 1.525 inches.
  • the actuating button 146 is adjacent to a first or proximal end 731 of the gripping portion 116. The button 146 is positioned so that a thumb 734 of the hand 714 gripping the gripping portion 116 can comfortably actuate the cleaning system 100 by pressing the button 146.
  • a center 738 of the button 146 is spaced 742 from the first end of the gripping portions 116 by about % of an inch to about 1 inch. It should be noted that the designation of the location of the first end of the gripping portion is somewhat arbitrary. Some observers consider the button 146 to be within a differently defined gripping portion of the cleaning system 100. The description above is intended to be exemplary only and is not intended to limit the invention.
  • the cleaning system 100 can be readily adapted to particular cleaning tasks.
  • the upper housing or transmission module 108 can have a length 750 that is relatively short when the cleaning system 100 is directed toward kitchen cleaning tasks such as the washing of dishes, glasses and pots and pans.
  • One embodiment directed toward these tasks includes an upper housing having a length 750 of about 2-1/2 inches.
  • the upper housing 108 can include features directed toward those tasks. For example, when the cleaning system 100 is directed toward cleaning a shower or bathtub area, the length 750 of the upper housing 108 can be longer.
  • the length 750 of the upper housing 108 can be selected to give the overall cleaning system 100 a longer reach.
  • overall cleaning system lengths of about 14 inches to about 40 inches can be directed toward using the cleaning system to reach across a tub to clean walls adjacent thereto or to clean the tub itself without stooping or kneeling.
  • Other sizes can accommodate the cleaning of a sink or other bathroom fixtures.
  • the cleaning system can be further adapted to particular cleaning tasks. For example, pot scrubbing may benefit from high torque being delivered to the cleaning head. On the other hand, bottle washing may benefit from high-speed brush rotation. Bathroom bowl cleaning may benefit from a slow brash rotation speed.
  • an upper housing with a higher torque motor or a transmission that provides high torque at reduced speed can be installed when the cleaning system is to be directed toward cleaning pots and other items with baked and burned on food.
  • an upper housing with a high-speed motor or a lower gear ratio may be used in conjunction with a bottle-washing cleaning head such as bottle washer 420 so that all surfaces of the bottle can be quickly wiped clean and a next bottle can quickly be washed.
