CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]     This Application claims the benefit of U.S. Provisional Application Ser. No. 60/739,559, filed on Nov. 23, 2005, the contents of which are incorporated herein by reference in its entirety for all that is taught and disclosed therein. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention pertains to a disposable cleaning head and adapter therefor that are positioned in a receptacle at the forward end of a handle, the cleaning head adapted for cleaning without scratching plated and painted surfaces of a vehicle, such as the wheel cover and the front grille. More particularly, this invention pertains to a cleaning head comprised of sponge-like cleaning elements affixed to a holder that is mountable in detachable fashion in the receptacle, wherein the cleaning head is held in frictional closure with and rotates relative to the adapter or is locked in place.  
         [0004]     2. Description of the Prior Art  
         [0005]     A cleaning head for use with a handle is disclosed in U.S. Pat. No. US-D496,138, issued Sep. 14, 2004, and a handle for use with a disposable cleaning head is disclosed in US-D496,512, issued Sep. 21, 2004, and Patent Publication 2004/0129296, published Jul. 8, 2004, the disclosures of each of these patent documents being specifically incorporated herein by reference.  
         [0006]     In general, the cleaning apparatus of the above patent documents comprises a cleaning head and a handle apparatus. The cleaning head comprises a cylindrical bundle of axial bristles arranged within a receiving sleeve detachably mountable to an end portion of the handle apparatus under friction closure. The handle apparatus includes an elongated handle including the cylindrical end portion for detachably mounting the cleaning head, and actuation means operably coupled to the handle and including a plunger, wherein actuation of the plunger ejects the cleaning head from the end portion.  
         [0007]     The cleaning head is particularly used for cleaning a toilet bowl and is discharged into the toilet bowl when the useful life is exhausted. The cleaning head, while believed suitable for the use in cleaning toilet bowls, has a bristle construction which may not be appropriate in cleaning other surfaces.  
         [0008]     Present day automobile wheels are often constructed with attractive designs to generate customer appeal. Customer demand is such that many different styles and configurations of wheels are necessary to meet the diverse taste of customers.  
         [0009]     There has developed a very lucrative market for both OEM and aftermarket wheels constructed with numerous different styles of spoke and aperture configurations combined to present an eye pleasing design. Many of these wheels incorporate attractive finishes, which may be constructed of expensive metal platings and the like. Such finishes often require a great degree of care in order to maintain a clean attractive appearance. This demand leads to a challenge for the automobile owner in keeping the wheels clean. During operation of the car, both the wheel and various component parts thereof and the vehicle trim may become covered with grease and other dirt, which detracts from the appearance of the automobile.  
         [0010]     What adds to the challenge of effective wheel cleaning is the fact that popular wheel designs often incorporate recesses, holes, crevices and spaces which have endless numbers of shapes, sizes and angles thus exhibiting a challenge to effective access by presently known cleaning brushes and pads.  
         [0011]     Commonly used tools, such as oversized sponges, long bristle brushes and sets of brushes with specific sizes and shapes have not provided a satisfactory solution to cleaning the dirt and grime without somehow degrading a surface finish.  
         [0012]     As an example, in many wheel designs, the depressions and openings therein are formed with radially inwardly turned peripheral lips which often collect dust and grime which is difficult to access with a typical sponge or brush. Those depressions and crevices often incorporate a triangular configuration such that a brush sized for ready access to the enlarged end of the triangle cannot be slid into the narrow end of the triangular crevice thus preventing access to the inturned peripheral lips for adequate cleaning thereof.  
         [0013]     Also, any effort to utilize a set of multiple brushes of different sizes and shapes is generally impractical. The expense of acquiring such sets of brushes and the challenge of having the properly sized brush readily available at the time it is needed renders the overall proposition quite unsatisfactory.  
         [0014]     Inability of the cleaning implement to reach awkward places often results in dirt, grime and dust being left on the vehicle part after the cleaning task is completed, thus leaving an unsightly appearance.  
         [0015]     Various different proposals have been made for solving these various problems. As an example, Sellers U.S. Pat. No. 5,077,857 discloses a polishing tool having an elongated stem mounting on one side a series of tufts of brush bristles and on the other side a layer of sponge-like material configured in a V-shape for accessing specifically shaped crevices and depressions.  
         [0016]     In recognition of the need for a device for cleaning lug nut wells, Gronkiewicz U.S. Pat. No. 6,067,686 discloses a generally tubular shaped sponge configured to be received telescopically within the lug nut well. Large U.S. Pat. No. 6,470,526 discloses a resilient pad fixedly attached to a handle with the pad formed by cylindrical segments stepped down in transverse cross-section toward the forward end of the handle.  
         [0017]     Such devices, while satisfactory for certain applications, have limited utility and have not been broadly accepted in the marketplace.  
         [0018]     Consequently, there exists a need for a wheel cleaning tool for accessing wheel indentations and apertures having different shapes, sizes and configurations and which accommodates wide ranges of such configurations. It is preferable if the cleaning task could be undertaken without subjecting the finish of the wheel to harsh rigid surfaces which might result in dragging grit over the finish resulting in scratching thereof.  
         [0019]     It is to be appreciated that there is a need for a cleaning head and holder which may be detachably connected to a handle, and configured to enable the user to clean recesses and surface indentations such as defined by wheel covers, trim, and other surfaces of an area.  
         [0020]     An object of this invention is the provision of improved cleaning apparatus having a shaped handle with ejection plunger and swiveling cleaning head that will enable the user to gain access to hard to reach locations and yet apply cleaning force as needed without damaging the vehicle surface being cleaned.  
         [0021]     Another object of this invention is the provision of a disposable cleaning head and adapter therefore which enables the cleaning head to be easily mounted to a handle and ejected from the handle and disposed of when the useful life of the cleaning head is reached.  
         [0022]     Another object is the provision of a cleaning head, having different construction and different cleaning elements, and an adapter, enabling different types of cleaning heads to be demountably attached to a receptacle at the end of an elongated handle, thereby enabling the cleaning tool available and the work to be performed to be customized.

The mounting stem  244  is in the form of a spike, or spear, and projects forwardly from the forward end face  50  of the base  42  to terminate in a pointed end  244   a,  which end is driven into the spherical shaped cleaning element  246 .  
         [0091]     In  FIG. 9 , a disposable cleaning head  330  comprises the base  42 , a mounting plate  344 , and a cleaning element  346 . The mounting plate  344  is generally flat, rectangular, and secured to the forward end of the base  42 . The mounting plate  344  may be integrally formed with the base  42  or formed as a separate element and secured to the base  42 .  
         [0092]     The cleaning element  346  is generally rectangular in shape and secured to the mounting plate  344 . The cleaning element  346  may be fixedly attached to the plate  344  by a suitable adhesive or be removably connected thereto.  
         [0093]     Although not shown, the cleaning head may comprise other arrangements and cleaning elements as described herein. For example, a cleaning element may be secured to the base  42  by means of one or more gripping fingers and receiving slots operating between the cleaning element and the base.  
         [0094]     In  FIG. 10 , according to this invention, a disposable cleaning head  430  comprises the base  42 , and a cleaning element  446 . A pair of fingers  445  upstand from the front face  50  of the base  42  and each terminates in a respective retention element  447 , such as an enlarged bead. The cleaning element  446  is comprised of a suitable sponge-like material and includes a pair of retention slots  449 . In practice, the fingers  445  are received in a respective slot  449 . The slots  449  are dimensioned to receive and form a frictional gripping engagement with the fingers  445  and the retention elements  447 .  
         [0095]     The frictional retention could be other than shown. For example, the retention fingers may comprise an annular or tubular projection, which projects forwardly from the front face  50  of the base  42 , and the tubular projection terminate in an enlarged retention rib or bead thereabout, and the receiving slot comprise a complementary annular slot, sized to receive and frictionally engage with the tubular projection and the retention rib.  
         [0096]     As illustrated in  FIG. 11 , according to this invention, in some applications a rib  66  and a detent  68  may operate between the cleaning head  30 ,  130 ,  230 ,  330 , and  430  and the inner wall  136  of the receptacle  28  wherein to prevent rotation of the cleaning head  30  relative to the handle  10 . Advantageously, in some applications, this interlocking engagement will operate to ensure that the cleaning head remains at a desired angular relation with the handle during a cleaning activity.  
         [0097]     Other combinations and structure, although not illustrated, are intended to be covered.
