  • the cleaning tool assembly 20 includes a cleaning tool 22 and a cleaning pad 24.
  • the various components are described in greater detail below.
  • the cleaning pad 24 is attached to the cleaning tool 22, and in one embodiment is releasably attached to the cleaning tool 22.
  • the resultant cleaning tool assembly 20 provides a plurality of cleaning surfaces for performing cleaning tasks, such as cleaning various hard surfaces of a bathroom.
  • the cleaning tool assembly 20 can incorporate a number of features highlighted below that promote convenient use under a variety of circumstances including, in one embodiment, delivering a cleaning solution (not shown), such as bleach, otherwise carried by the cleaning pad 24.
  • a cleaning solution not shown
  • the cleaning tool 22 includes a handle 30 and a head assembly 32.
  • the head assembly 32 can be attached to the handle 30 in a variety of fashions, and is described in greater detail below.
  • the handle 30 is configured to be extendable, as best shown in FIGS. 2 A and 2B.
  • the handle 30 is configured to be transitionable between a retracted state or position (FIG. 2A) and one or more extended state(s) or position(s) (FIG. 2B) in which an overall length of the handle 30 is increased as compared to the retracted position.
  • the extendable feature of the handle 30 is achieved, in one embodiment, by forming the handle 30 to include a grip portion 40 and an extension shaft 42 (shown best in FIG. 2B).
  • the shaft 42 is slidably received within the grip portion 40 and is connected to the head assembly 32. With this configuration, the shaft 42 can be longitudinally extended and retracted relative to the grip portion 40 to increase and decrease a length, respectively, of the handle 30 and thus a longitudinal position of the head assembly 30 relative to the grip portion 40.
  • the handle 30 further includes a locking mechanism 44 (referenced generally) adapted to selectively maintain or "lock" the handle 30 at a selected longitudinal length.
  • the grip portion 40 is generally tubular in nature, and in one embodiment includes a grip body 46, an intermediate segment 48 and an end segment 50.
  • the grip body 46, the intermediate segment 48 and the end segment 50 can be formed separately and assembled to one another; alternatively, components of the grip portion 40 can be integrally formed.
  • the grip body 46, the intermediate segment 48 and the end segment 50 collectively define an internal passage 52 (shown with dashed lines in FIG. 2B) sized to receive the shaft 42.
  • the grip body 46 can assume a wide variety of forms, and preferably provides a contoured outer surface 54 configured to facilitate grasping thereof by a user's hand (not shown).
  • the outer contoured outer surface 54 extends between a proximal end 56 and a distal end 58.
  • the grip body 46 forms a cavity 60 (referenced generally in FIG. 2B) adjacent the distal end 58 and within which a lever assembly 62 is maintained, as described below.
  • the intermediate segment 48 of the grip portion 40 is affixed to, and extends rearwardly from, the proximal end 56 of the grip body 46, and thus can assume a variety of shapes and sizes.
  • the intermediate segment 48 is a tube having an outer diameter less than an outer diameter of the grip body 46. Because, in one embodiment, it is not intended for a user to grasp the intermediate segment 48 during use, the intermediate segment 48 can be thinner than the grip body 46, and thus less expensive. Alternatively, the intermediate segment 48 can be commensurate in thickness with the grip body 46, and, in one embodiment, is integrally formed with the grip body 46.
  • the intermediate segment 48 is of sufficient length to longitudinally space the grip body 46 and the end segment 50 at ergonomically desired positions for convenient, natural grasping by both hands of a user (i.e., one hand grasps the grip body 46 and the other hand grasps the end segment 50).
  • the intermediate segment 48 defines a spacing between the grip body 46 and the end segment on the order of 5 - 15 inches. Alternatively, other dimensions, either lesser or greater, are also acceptable.
  • the end segment 50 is connected to the intermediate segment 48 opposite the grip body 46, and can assume a variety of shapes and sizes.
  • the end segment 50 forms a hole 84 that provides a convenient means for hanging the cleaning assembly 20 from a hook (not shown) or similar body when not in use.
  • the hole 84 can be eliminated.
  • the end segment 50 preferably has an increased outer diameter as compared to the intermediate segment 48, sized for convenient grasping by a user (not shown).
  • the grip body 46, the intermediate segment 48, and the end segment 50 are separately formed and subsequently assembled, differing materials can be employed in the manufacture of each component.
  • the grip body 46 is formed of a molded plastic
  • the intermediate segment 48 is a more rigid metal-based material
  • the end segment 50 has a rubberized exterior for enhanced handling by a user (not shown).
  • the end segment 50 need not have a rubberized exterior, and can be formed from any acceptable material such as polypropylene, thermoplastic rubber or ABS.
  • the components are preferably rigidly affixed to one another, such as by frictionally mounting opposing ends of the intermediate segment within corresponding passages of the grip body 46 and the end segment 50.
  • the grip body 46 can define a passage (not shown) adjacent the proximal end 56 thereof sized to frictionally receive and maintain a portion of the intermediate segment 48.
  • Other attachment techniques e.g., adhesive, mechanical connectors, etc.
  • the grip body 46, the intermediate segment 48 and the end segment 50 can be integrally formed.
  • one or more of the grip body 46, the intermediate segment 48 and/or the end segment 50 can be eliminated.
  • the grip portion 40 is sized to slidably maintain the shaft 42 as described below.
  • the lever assembly 62 is connected to the grip body 46.
  • the lever assembly 62 forms a portion of one embodiment of the locking mechanism 44.
  • the lever assembly 62 includes a lever arm 64, a pin 66, and a biasing device 68.
  • the lever arm 64 is pivotally mounted to the grip body 46 via the pin 66, with the biasing device 68 biasing the lever arm 64 to a locked position.
  • the lever arm 64 defines a trailing end 70, an intermediate portion 72 and a leading end 74 terminating in a finger 76.
  • the trailing end 70 has an increased width as compared to a remainder of the lever arm 64, and defines a central depression 78 (referenced generally) sized for receiving a user's thumb and/or finger (not shown).
  • the trailing end 70 can assume a variety of other shapes and/or sizes.
  • the lever arm 64 is sized in accordance with the cavity 60 otherwise formed by the grip body 46, and is preferably configured such that an outer surface 80 thereof generally matches the contour of the outer surface 54 of the grip body 46, resulting in a streamlined appearance.
  • the intermediate portion 72 provides a pivot point at the pin 66, and defines an inner surface 82 configured to interface with the biasing device 68.
  • the leading end 74, and in particular the finger 76 extends downwardly (relative to the orientation of FIG. 3A) from the intermediate portion 72, and is adapted to selectively mate with a corresponding portion of the shaft 42, as described below.
  • the pin 66 can assume a variety of forms, and is generally constructed to pivotally connect the lever arm 64 to the grip body 46.
  • the biasing device 68 can have a number of different constructions, and is adapted to bias the lever arm 64 toward a locked position (i.e., biases the lever arm 64 clockwise (about the pin 66) relative to the orientation of FIG. 3A).
  • the biasing device 68 is a torsional spring located within the cavity 60 and bearing against the inner surface 82 of the intermediate portion 72 between the pin 66 and the trailing end 70; this configuration biases the lever arm 64 to rotate or pivot clockwise relative to the orientation of FIG. 3 A.
  • the cavity 60 can be sized to limit overt movement or rotation of the lever arm 64 in response to the force generated by biasing device 68, such as by abutting a top surface of the lever arm 64 in the locked position of FIG. 3 A.
  • a number of other configurations for the lever assembly 62 can be employed, and the lever assembly 62 need not be permanently attached to the grip body 46.
  • the shaft 42 is, in one embodiment, a rigid tubular structure defining first and second ends 90, 92.
  • the shaft 42 forms a longitudinal passage 94 (FIG. 3A) and a plurality of transverse locking recesses 96 (FIG. 3A).
  • the longitudinal passage 94 extends between the first and second ends 90, 92.
  • the longitudinal passage 94 is sized to receive and maintain a corresponding portion of the head assembly 32 as described in greater detail below.
  • the shaft 42 includes an opposing pair of grooves 98 that further facilitate attachment of the head assembly 32 to the shaft 42 (it being understood that for purposes of clarification, the head assembly 32 is shown disassembled from the shaft 42 in FIG.
  • the recesses 96 are spaced along an exterior of the shaft 42 and are sized to selectively receive the finger 76 (FIG. 3A) provided by the lever assembly 62.
  • the recesses 96 can be identically sized holes or other forms of indentations relative to an outer diameter of the shaft 42.
  • the recesses 96 form a complimentary portion of the locking mechanism 44.
  • the finger 76 is received within a corresponding one of the recesses 96. Because the lever arm 64, and thus the finger 76, is biased to the locked position of FIGS.
  • the locking mechanism 44 "locks” the grip portion 40 relative to the shaft 42.
  • the locking mechanism 44 can be “released” by a user (not shown) pressing down (relative to the orientation of FIG. 3A) on the trailing end 70 of the lever arm 64 with sufficient force to overcome the biasing device 68. This action, in turn, pivots or rotates the finger 76 out or away from the recess 96, allowing the shaft 42 to freely slide relative to the grip portion 40.
  • the locking mechanism 44 can slide the shaft 42 relative to the grip portion 40 to position the handle 30 at a desired length.
  • the plurality of recesses 96 can include first, second and third recesses 96a - 96c (as shown in FIG. 2B). In a retracted position, the grip portion 40 is positioned relative to the shaft 42 such that the finger 76 can engage within the first recess 96a.
  • the grip portion 40 In a first extended position, the grip portion 40 is positioned relative to the shaft 42 such that the finger 76 nests within the second recess 96b upon releasing the lever arm 64 (with the biasing device 68 acting to bias the lever arm 64 toward the locked position in which the finger 76 extends within the second recess 96b once properly aligned).
  • the handle 30 has an overall length in the first extended position greater than a length in the retracted position.
  • a second extended position of the handle 30, with a length greater than the first extended position is achieved upon aligning the finger 76 with the third recess 96c.
  • the number of extended positions available with the handle 30 is thus a function of the number of recesses 96 (it being understood that more or less of the recesses 96 can be provided as compared to the illustration of FIG. 2B).
  • a spacing between adjacent ones of the recesses 96 can be uniform along a length of the shaft 42, or can vary.
  • the shaft 42 is preferably configured such that in the retracted position, the head assembly 32 abuts the distal end 58 of the grip body 46 thereby defining a minimal overall length of the cleaning assembly 20, as shown in FIG. 2A.
  • the handle 30 has a length on the order of 17.5 inches when fully retracted, although other dimensions are also acceptable.
  • the head assembly 32 longitudinally moves relative to the grip portion 40, and in particular the grip body 46, with longitudinal movement of the shaft 42 relative to the grip portion 40.
  • the handle 30 can be constructed such that the grip body 46 is directly connected to the head assembly 32, with extension of the handle 30 being accomplished between the grip body 46 and the end segment 50.
  • the grip portion 40 and the shaft 42 are configured to minimize or eliminate undesired rotation of the shaft 42 relative to the grip portion 40, thus ensuring proper alignment between the finger 76 and a corresponding one of the recesses 96 otherwise provided by the shaft 42.
  • the shaft 42/grip body 46 interface is non-circular in transverse cross-section such that the shaft 42 does not readily rotate relative to the grip body 46.
  • an outer surface of the shaft 42 (and corresponding shape of the passage 52 provided by the grip body 46) can be obround in transverse cross-section as shown; alternatively, other cross-sectional shapes such as rectangular, square, triangular, etc., are also acceptable.
  • the head assembly 32 is adapted for connection to the handle 30 and generally includes a neck 110 and a head 112. As described in greater detail below, the neck 110 can be connected or assembled to the handle 30 and maintains the head 112. The head 112, in turn, provides a variety of cleaning surfaces and maintains the cleaning pad 24.
  • the neck 110 is an elongated body configured to be pivotally attached to the head 112, and defines a handle end 114, a head end 116, and an intermediate region 118 extending between the ends 114, 1 16.
  • the handle end 114 is adapted for mounting to the handle 30 (FIG. 2A) and in particular the shaft 42 (FIG. 3A). Mounting of the neck 110 to the handle 30 can be accomplished in a variety of fashions, and in one embodiment, the handle end 114 forms a pair of spaced legs 120a, 120b each including an outwardly extending tab 122 (the tab 122 associated with the leg 120a is visible in the view of FIG. 4).
  • the handle end 114 extends from a shoulder 124 of the intermediate region 118, with the legs 12Oa 5 120b combining to define an outer diameter that is less than an outer diameter of the shoulder 124.
  • the legs 120a, 120b are inwardly deflectable toward one another, but naturally assume the position shown in FIG. 4.
  • the handle end 114 is adapted for mounting to the first end 90 of the shaft 42 as best shown in FIG. 5 (that otherwise depicts a portion of the shaft 42 in cross-section and apart from the grip portion 40 (FIG. 2A)). More particularly, the neck 110 is assembled to the shaft 42 by inserting the handle end 114 within the passage 94 of the shaft 42 at the first end 90 thereof.
  • the legs 120a, 120b combine to define an outer diameter that is slightly greater than a diameter of the passage 94.
  • the deflectable nature of the legs 120a, 120b allows the handle end 114 to be inserted within the passage 94.
  • the handle end 114/shaft 42 are configured such that the locked relationship is not readily reversed by a user (e.g., a user cannot easily remove the handle end 114 from the passage 94 once assembled) due to, for example, abutment between the tabs 122/shaft 42 along a plane (referenced generally at 125 in FIG. 5) that is perpendicular to a longitudinal axis of the shaft 42; alternatively, the handle end 114/shaft 42 can be configured such that the neck 110 is releasable from the shaft 42. Even further, the neck 110 and the shaft 42 can be integrally formed. Conversely, a variety of other interlocking designs can be employed. For example, the legs 120a, 120b can be provided as part of the shaft 42 for insertion within a corresponding passage in the neck 110.
  • the head end 116 of the neck 110 is, in one embodiment, configured for pivoting or rotating connection to the head 112 and can include a transversely extending shank 126 and a rounded surface 128. Assembly of the head end 116 to the head 112 is a function of a construction of the head 112 itself, and thus is described in greater detail below. In general terms, however, the neck 110 can assume a variety of configurations varying from that shown, each capable of facilitating connection to the head 112.
  • the intermediate region 118 preferably has a contoured shape, tapering in outer diameter from a first section 130 adjacent the handle end 114 to a second section 132 adjacent the head end 116.
  • This one preferred configuration renders the first section 130 of appropriate size and shape for convenient grasping by a user's hand (not shown), such that a user can readily operate the cleaning assembly 20 (FIG. 1) via the neck 110.
  • the handle 30 (FIG. 1) can be removed and a cleaning operation performed by simply grasping and manipulating the neck 110, and in particular the first section 130.
  • the second section 132 is preferably sized and shaped for rigidly engaging a corresponding portion of the head 112, as described below.
  • the intermediate region 118 can assume a wide variety of other shapes and sizes.
  • the head 112 is generally triangular in shape and includes a plate 140, a support pad 142 and a mounting device 144 (referenced generally).
  • the plate 140 maintains the support pad 142 and is attachable to the neck 110.
  • the support pad 142 maintains the mounting device 144 that is otherwise adapted to selectively receive the cleaning pad 24 (FIG. 1) as described below.
  • the head 112 can be described as having a first side 146 (defined by the plate 140), a second side 148 (referenced generally in FIG. 4; defined by the support pad 142 opposite the first side 146), and a perimeter 149 defined by the support pad 142.
  • the generally triangular shape in conjunction with a location and pivoting direction of the neck 110 relative to the head 112 creates an identifiable front 150 and a back 152, corresponding generally with a visual impression created upon a user when the cleaning tool assembly 20 is grasped at the handle 30 (FIG. 1).
  • the plate 140 has a leading section 154, a central section 156 and a trailing section 158.
  • the leading section 154 is defined at an apex of the triangular shape defined by the plate 140 (i.e., the front 150), whereas the trailing section 158 terminates at an edge 160 opposite the leading section 154 (i.e., the back 152).

  • the cutout segment 226 affords access to a sufficient surface area of the cleaning pad 24 to allow for forceful pulling of the cleaning pad 24 from the head 112 (e.g., the user can apply sufficient pulling force to the cleaning pad 24 to disengage the cleaning pad 24 from the connection bodies 230).
  • the replacement cleaning pad (not shown) is readily assembled to the head 112 in a similar fashion.
  • the cleaning pad 24 can include a tab (not shown) or similar structure that can be grasped by a user during a cleaning pad removal operation.
  • Alternative releasable connection designs can also be employed, such as providing the cleaning pad 24 with an elastic perimeter that "captures" the head 112; forming the cleaning pad 24 to include a pocket that nests about the head 112; etc. Regardless, the head 112 remains part of the cleaning tool 22, and only the cleaning pad 24 is removed/replaced, thus minimizing disposal/replacement costs.
  • the cleaning tool assembly, cleaning tool, kit, cleaning pad and method of use of the present invention provides a marked improvement over previous designs. Multiple hard surfaces of a room or other area are readily cleaned using a single device that provides diverse cleaning characteristics.
  • the extendable handle allows the user to stand while cleaning high or low surfaces with minimal exertion.
  • the handle can further pivot with respect to the head where desired, and can also be locked with respect to the head where desired.
  • the cleaning pad can dispense bleach where desired, and is easily replaced.
  • the cleaning tool can be configured to contain a volume of liquid (e.g., water) that is selectively dispensed during use.
  • a volume of liquid e.g., water
  • One such possible configuration includes the handle being hollow and in fluid communication with an exit port(s) on the head; liquid stored in the handle can thus be dispensed via the exit port(s).
  • the head can be configured to define a scoop-like top surface; with this design, water or other liquid can be temporarily stored in the scoop-like surface and then dispensed as desired by the user, such as when cleaning a wall.
  • the head can include a sponge-like material that holds water or other liquid; during use, as pressure is applied by the user to the head (such as via the handle), the contained water or other liquid is then released from the sponge-like material.
  • the head can be configured to form or include a thermoplastic rubber (TPR) or similar material, allowing the head to be used as a squeegee.
  • TPR thermoplastic rubber
