Abstract
A rotating dish brush is described having a handle and a head. The handle includes a neck connected by a pin to the head. The rotating connection of the handle and head are limited by a pair of stops that also function as areas of force transfer from the handle to the head. The stops limit the relative movement of the head and handle between a first position and a second position. The head includes a set of bristles having a generally hemispherical shape. A loop is provided on the handle for hanging the rotating dish brush when it is not in use.
Description




BACKGROUND




1. Technical Field




The present disclosure relates to cleaning devices. More particularly, the present disclosure relates to cleaning devices for dishes having movable brushes.




2. Background of Related Art




Dish brushes have configurations that typically include an elongate handle connected to a bristled brush. The handle is often capable of bending and the brush has one or more sets of bristles extending in three dimensions enabling a user to clean any portion of an interior of a bottle, for example.




In U.S. Pat. No. 882,021 to Schigelinsky, a bottle cleaner is described having an elongate handle section connected to a cleaning section. Schigelinsky teaches a mechanism actuated from the handle for moving a tip of the bottle cleaner from a position aligned with the handle to a second position at a right angle to the handle. This feature enables the cleaning strip to be used for cleaning or scraping the sides of the bottle. While Schigelinsky provides for cleaning at a right angle relative to the handle, the ability to apply a cleaning force is limited by the length of the lever arm and the right angle application of the cleaning section. In addition, Schigelinsky limits the bottle cleaning section to being aligned with the handle or being at a right angle to the handle and therefore lacks the ability to apply a cleaning section through a range of angles relative to the handle.




A bottle brush having a pivoted handle is described in U.S. Pat. No. 2,584,503 to Schleenbaker and includes a body portion having a loose pivotal connection to a handle. The handle includes a bend in proximity to the body portion. The body portion has an elongate cylindrical tubular shape having a cut-out portion and includes two sets of bristles extending from U-shaped clips. A first set of bristles extend radially through an arc of approximately 270 degrees and the second set of bristles are generally aligned with the elongate tubular shape of the body portion and perpendicular to the first set of bristles.




In use, the body portion of Schleenbaker is pivoted to a first position wherein the bent portion of the handle is positioned partially within the cut away portion of the body and the elongate axis of the body assumes a substantially straight line with the handle. After positioning the body portion within the bottle, the body can be positioned using the movements of the handle to pivotally position the body between the First position and a second position wherein the body portion is generally perpendicular to the bent portion of the handle.




Schleenbaker, however, is limited by its force transfer configuration wherein, Schleenbaker relies on the transfer of force through a U-shaped clip functioning as an axle for the pivotal connection between the handle and the tubular body portion. Thus, the U-shaped clip, a point of rotation, is subject to both the frictional forces of rotation and a cleaning force from the handle. This configuration produces structural stresses such as shearing forces on the U-shaped clip by the tubular walls that are indicative of a cleaning device that is limited to applying light or superficial cleaning forces. Thus, the structural configuration Schleenbaker as shown is not suited for applying a broad range of cleaning force loads.




In U.S. Pat. No. 5,317,779 to Hoagland, a utility kitchen brush is described having a gently curved handle fixedly connected to a substantially rectangular bristle block. An array of bristles extends downward from die bristle block. A first scraper and a second scraper are positioned on the bristle block and define a notch. Hoagland, however, lacks the flexibility required for many cleaning applications by having a fixed handle to bristle block connection that does not permit the bristle block to accommodate variations in the surface to be cleaned without compensating by also moving the handle. This limits the application of Hoagland in a dimensionally constraining environment such as interior bottle cleaning. Thus, the flexibility in which Hoagland can be employed in cleaning processes is limited by the fixed relationship between the cleaning surface of the brush and scraper to the handle.




A continuing need exists for a rotating dish brush having a structure suitable for receiving a range of cleaning forces and a cleaning bead that can be rotated relative to the handle for employment of the brushing surface through an advantageously controlled range of angles.




SUMMARY




A rotating dish brush is described including a handle and a head. The handle has a distal end and a proximal end defining a longitudinal axis. The distal end of the handle defines a neck having a tip including a first planar surface connected with a second planar surface. The head has a generally spheroid shape with a first end opposing a second end. The second end is positioned on the neck and the first end has a single set of bristles. The bead is configured for rotation relative to the neck and defines a channel for receiving the neck aligned with the first longitudinal axis. The channel includes a channel planar surface configured for mating with the first planar surface and the second planar surface of the neck for the transfer of forces from the handle to the head.




The invention, together with attendant advantages, will be best understood by reference to the following detailed description of the invention when used in conjunction with the figures below.

and/or head


40


have rotated approximately 60 degrees such that there is a 60 degree offset between the primary orientation of bristles


50


and first longitudinal axis


13


of handle


20


.




Referring now to

FIG. 3

, head


40


has a generally spheroid shape having an elliptical cross section about the first plane defined by first axis


13


and second axis


15


. Second end


44


defines a channel


60


aligned with the first plane and having a generally rectangular cross section when viewed perpendicular to the first plane. Channel


60


has opposing walls


62


and


64


parallel to the first plane and opposing walls


63


and


65


along the perimeter of head


40


. Channel


60


also defines a channel wall or a planar surface


66


positioned adjoining walls


62


,


63


,


64


, and


65


as the distal most portion of the channel when brush


10


is in the first position. Planar surface


66


and the distal most edge of neck


30


are positioned as interfaces providing an advantageous surface area for force transfer between handle


20


and head


40


.




Wall


65

65


is preferably of greater length than the length of wall


63


. Wall


63


has a tapered edge


67






Head


40


has two concave portions


46


and


48


opposing walls


62


and


64


, respectively. A through hole B is defined through concave portions


46


and


48


as well as walls


62


and


64


. Through hole B defines a third longitudinal axis


17


perpendicular to the first plane and is positioned as a point of rotation for handle


20


. Head


40


also includes axel or pin


35


suitably configured for positioning within hole B and hole


31


of neck


30


. Pin


35


has tapered ends


35




a


and


35




b


that are conformingly tapered to be flush with concave portions


46


and


48


when positioned in head


40


.




Referring now to

FIGS. 4A and 4B

, brush


10


is shown with neck


30


at least partially positioned in channel


60


of head


40


for rotation about axel


35


. Neck portion


30


defines a first flat planar surface


32


connected by a rounded edge


33


to a second flat planar surface


34


. First planar surface


32


is approximately perpendicular to first longitudinal axis


13


and second planar surface


34


places the relative position of handle


20


and head


40


approximately 60 degrees from the first position. The primary angle of orientation of bristles


50


is defined as being perpendicular to planar surface


66


.




In the first position, a first planar surface


32


is positioned parallel to and in direct contact with planar surface


66


of head


40


and functions both as stop limiting the travel of handle


20


and a stable area for the transfer of forces from handle


20


to head


40


. First surface


32


and channel wall


65


are not in contact and are positioned apart in the first position. Thus, wall


65


does not act as stop to limit the travel of handle


20


from rotating in the first plane.




In the second position a second planar surface


34


is positioned parallel to and in direct contact with planar surface


66


and functions as a stop limiting further movement of handle


20


relative to head


40


in cooperation with edge


67


of wall


63


. Edge


67


is advantageously positioned as a second area for receiving the transfer of the cleaning force of the handle with planar surface


66


in the second position.




A rounded edge surface


33


enables a suitable transition between planar surfaces


32


and


34


and acts as an intermediate area of force transfer from handle


20


to head


40


between the first and second positions. Surfaces


32


,


33


, and


34


are force transfer areas cooperatively positioned in mating contact with surface


66


for the transfer of forces from handle


20


to bristles


50


. Surfaces


32


and


34


are also positioned to functions as stops limiting the rotation between handle


20


and head


40


in the first and second positions, respectively.




While handle


10


and head


40


are described as having the ability to rotate up to approximately 60 degrees, it is readily envisioned that the application of varying handle geometries as well as head


40


and neck


30


configurations could accommodate rotating up to and in excess of 180 degrees.




Rotating dish brush


10


can be employed washing, scrubbing, or scraping items such as dishes as well as home or vehicular related products, but is illustrated in

FIGS. 5A-5B

in one preferred application in conjunction with washing common household glassware such as a drinking glass


80


. Brush


10


is initially positioned for at least partially penetrating into an opening


82


defined by a lip


81


of glass


80


. Head


40


is preferably in the second position when penetrating into opening


82


such that head


40


has a reduced frontal area when viewed from a cross-section perpendicular to longitudinal axis


13


. The ability of brush


10


to enter glass


80


in the general direction of arrow-A, or any other opening, is limited only the geometry and dimensions of that opening relative to the dimensions of brush


10


. Brush


10


is configured to be positioned through openings, such as opening


82


, in any variation of angles between longitudinal axis


13


defined by handle


20


and head


40


throughout the complete range of approximately 60 degrees between the first position and the second position. Once head


40


is at least partially positioned within glass


80


, bristles


50


can be positioned to contact an inside surface


83


of a cylindrical wall of glass


80


.




The cleaning process with brush


10


preferably includes moving brush


10


in any direction or combination of directions including generally parallel, transverse, or rotated about longitudinal axis


13


. Handle


20


can automatically adapt or change its relative angle to head


40


to accommodate variations in surface


83


within the range of movement between handle


20


and head


40


. The user can also drive the change of relative angle between handle


20


and head


40


at their preference to increase the cleaning force component aligned with the angle of orientation of bristles


50


, for example. Brush


10


, at the convenience of the user is positioned approximately in the first position for cleaning of an inside bottom surface


84


of glass


80


. The cleaning process of glass


80


is enhanced by the ability of the user to apply a strong cleaning force through handle


20


onto bristles


50


through the full range of approximately 60 degrees of brush


10


. Brush


10


is withdrawn from glass


80


in the direction opposing arrow-A in any manner suitable for passage through opening


82


.




The limiting of handle


20


in the second position to approximately 60 degrees from the first position advantageously keeps a sizeable component of the cleaning force along handle


20


applied along the primary angle of orientation of bristles


50


. In addition the approximately 30 degree angle of handle


20


from the plane of application of the bristles in the second position combined with the dimensions of head


40


and the length of bristles


50


provides a stand-off to protect the fingers of the user from being inadvertently scraped during cleaning.
