Adjustable angle cleaning brush head
Adjustable angle cleaning brush comprised of a handle and rotatably attached first longitudinal brush head and a second longitudinal brush head that are side by side and parallel to each other in one configuration and rotate out to a T position with respect to the handle in a second configuration. One end of each brush head is fixedly attached to a pinion gear within the handle. The pinion gears engage a centrally located rack so that when a user pushes up on an actuation button attached to the rack, the brushes rotate out into a T position. They are held in a T position by a spring biased post. The user can press on the post to return the brush heads to the side by side position.

DESCRIPTION OF ATTACHED APPENDIXNot Applicable
BACKGROUND OF THE INVENTIONThis invention relates generally to the field of hand held cleaning brushes and more specifically to an adjustable angle cleaning brush head.
Cleaning brushes are well known in the housewares industry. They generally include a rigid handle and a brush head. Brushes are made in a variety of configurations including standard bottle brush designs that employ a central twisted wireform that holds bristles perpendicular to the wireform. Another standard brush configuration includes a rigid backing plate that has a plurality of bristles inserted into pre-formed holes in the plate. This type of brush can have a handle extending from its backing plate, or can include a griping portion directly on top of the backing plate.
For certain cleaning applications it is beneficial to have a brush head that is capable of bending or rotating to one side to help the brush head reach hard to get at spaces such as the rear portion of a kitchen faucet, or behind the spokes of a vehicle tire rim. A number of inventors have addressed this problem to some degree. W F Hoerle in his patent U.S. Pat. No. 2,379,962 shows a cleaning tool that includes a clevis joint to allow the brush head to rotate and bend. McLaughlin et al. in their patent U.S. Pat. No. 4,908,900 shows a bristle brush whose head can be rotated sideways for helping to clean ice and snow off a vehicle windshield. Lee in her patent D294886 shows a bent head for a cleaning brush for cleaning radiators and the like. Peake et al in their patent U.S. Pat. No. 6,032,316 shows a plate that includes bristles where the plate can pivot and be set at an angle with respect to a surrounding frame for shoe cleaning purposes. Weber et al in their patent U.S. Pat. No. 6,134,738 discloses a toilet cleaning brush that has a head that can be bent for fitting into the bowl more easily. Li in his patent U.S. Pat. No. 6,240,58 shows a wheel cleaning brush whose head can be bent. And Le Van in his patent application 2007/0297846 discloses a rim detailing brush that has a multiple replaceable cleaning heads.
However, all the above sited patents contain deficiencies with regard to providing a bendable brush head for reaching hard to get at spaces such as behind the spokes of a vehicle rim or behind a faucet set mounted on a kitchen sink. None of the sited patents except the McLaughlin patent show a way to change the angle of a brush head and lock it in place at that angle. The McLaughlin patent does not show a brush head that can be quickly turned. It must be manually removed from the handle and replaced in a different orientation. None of the above sited patents show a side by side pair of brush heads that can be quickly, by the push of a button, rotated outward to form a T shape with respect to the handle.
BRIEF SUMMARY OF THE INVENTIONThe primary object of the invention is to provide a hand held cleaning brush tool whose bristle brush head angle can be adjusted and locked in place by the user.
Another object of the invention is to provide a cleaning brush head that is composed of two brushes that can be quickly and easily rotated from a parallel side by side position to a perpendicular T shaped position.
Another object of the invention is to provide a cleaning brush head that allows the user to clean behind hard to reach areas such as behind spokes of a vehicle tire rim.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
In accordance with a preferred embodiment of the invention, there is disclosed adjustable angle cleaning brush head comprising: a first brush head, a second brush head, a brush angle change button, a hollow main handle, a slide button, a slide button track, a locking post, a locking post spring, a rack tension spring, a first pinion gear, a second pinion gear, a rack, and a rack extension shaft, said hollow handle enclosing said rack and said rack extension shaft and said tension spring which are all placed longitudinally within said handle, said hollow handle being widened at the uppermost portion to retain said first and second pinion gears, said rack extending out of the top portion of said handle, said slide button fixedly attached to said rack extension shaft, said tension spring attached at one end to said slide button and at the opposite end to a retaining post within the lower portion of said hollow handle, said first pinion gear rotatably fixed by a shaft on the upper left side of said rack and said second pinion gear rotatably fixed by a shaft placed on the upper right side of said rack, said first and second gear shafts rotatably attached to the said widened portion of said handle, said first and second brush heads being constructed in a standard longitudinal bottle brush format, said first brush head fixedly attached to said first pinion gear and said second brush head fixedly attached to said second pinion gear so that both said brush heads are in close proximity to and parallel to each other, said first and second brush heads capable of rotating outwardly to form a T shape with respect to said handle when a user slides said slide button along said slide button track located on said handle in an upward motion toward said brush head portion which causes said rack to move upward and force said first pinion gear to rotate counter clockwise and said second pinion gear to rotate clockwise, said first and second brush heads capable of being fixed in place in said T position when said spring biased locking post engages an aperture in the side of said hollow handle, said first and second brush heads capable of being disengaged from said T position and returning to said side by side parallel position when a user presses on the tip of said locking post so that it is freed from said side aperture thereby allowing said rack to be pulled downward.
The drawings constitute a part of this specification and include exemplary embodiments to the invention, which may be embodied in various forms. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged to facilitate an understanding of the invention.
