Abstract:
A rotary brush including an elongated handle and brush head and a rotary swivel joint between the handle and brush head allowing the brush to rotate to reach hard to access places when used for cleaning.

Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
     The present invention relates to a household cleaning brush and, in particular, to a brush having a swivelling head which rotates in order to reach hard to access areas. 
     Conventional household brushes find utility in kitchen and bathroom and other areas to be cleaned in a normal household. An example of this type of brush is shown in my own U.S. Design Patent 357,586, which shows a long handled brush having a generally rectangular block head design with the ends rounded. This and other similar brushes are designed to clean hard to reach areas, such as under the sink, behind tubs, toilet bowls, and the like. 
     The present invention relates to a similar brush which is specifically designed to access bathtubs and similar hard to reach areas. The brush is improved through the use of a rotating or swivelling head and unique connection between the head and the brush handle. The swivelling head allows a user to reach hard to access areas without having to manipulate the handle. This is particularly useful where there is little room in an area to be cleaned. This also aids people using the brush who may have limited physical abilities such as older and disabled individuals. The brush includes a unique rotating handle to brush head connection including a set of resilient arms and an annular o-ring connector which enables the brush head to easily rotate relative to the handle. 
     The length and shape of the handle provides distinctive anthropometric and ergonomic advantages that enables the user to efficiently and conveniently scrub and clean a bathtub eliminating extreme and awkward physical postures. The long handle and rotational brush movement allows a user to assume a minimal leaning position at the side of the bathtub resulting in the need of a minimal amount of arm and hand strength and flexibility to complete the cleaning operations. The torpedo shape and free rotating brush head scrubs and cleans as it is pushed across the surface accommodating the varied angles and curves found in a standard bathtub and it&#39;s surrounds. 
     Among the objects of the present invention is the provision of an improved brush design having a swivelling head to reach hard to access cleaning areas. 
     Another object is the provision of a brush structure which is more convenient and facile for cleaning a bathtub and it&#39;s surrounds while alleviating and reducing awkward and vigorous physical posturings heretofore required in the typical bathtub cleaning process. 
     Another object is the provision of a brush having a hand-to-floor length handle for increased efficiency and convenience in cleaning hard to access areas. 
     Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limited, but merely as the basis for the claims and as a basis for teaching one skilled in the art how to make and/or use the invention. 
     Referring to the drawings, a brush  10  in accordance with the present invention includes a brush head  12  and an elongated handle  14  which allows the entire limits of a bathtub to be reached during the cleaning process. The handle  14  includes an angularly disposed end  16  for connection to the brush head  12 . The end  16  of the handle  14  is a trifurcated structure formed of three resilient, arcuate shaped, arms  18  separated by elongated slots  20  which extend the entire length of the arms  18 . A plastic O-ring  22  is circumferentially molded on the outside peripheral edges of the arms  18 . 
     A brush head  24  is torpedo shaped having a tapered front end  26  and a flat rear wall  28 . An opening  30  molded into rear wall  28  of the brush head  24  extends longitudinally to the front end  26  and is sized to receive the handle end. The opening  30  includes an annular groove  32  located toward the closed end of the opening  30 . The groove  32  is sized to receive the plastic O-ring  22  when the handle end  16  is inserted into the opening  30  and snaps in place by the interaction of the O-ring  22  and groove  32 . This connection securely holds the handle and brush head together while permitting the brush head  24  to rotate relative to the handle  14 . It will be appreciated that the brush head is provided with bristles  36 , as shown in FIGS. 1 and 3, which are connected into holes  34  formed in the brush head  24 . 
     In use the brush head  24  swivels with respect to the handle  14  due to the rotational movement between the O-ring  22  and the annular groove  32  enabling a user to reach hard to access areas when cleaning in, for example, kitchen and bathroom areas. 
     While various preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention as defined in the appended claims.
