Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved toothbrush system with an internal water delivery system operable from a shower embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the new and improved toothbrush system with an internal water delivery system operable from a shower is a system 10 comprised of a plurality of components. In their broadest context, the components include an adaptor, a toothbrush, and a hose. Each of the individual components is specifically configured and correlated one with respect to the other so as to attain the desired objectives.
One central component of the system 10 of the present invention is a hollow cylindrical adapter 12. Such adaptor is removably positionable on a shower between the water outlet line 14 and the shower head 16. The adaptor is formed to have an inlet end 18. The inlet end is formed with internal screw threads 20 for coupling to the water outlet line which brings the water to the shower head. The adaptor is also formed to have an outlet end 22. On the outlet end are external threads 24 for coupling to the shower head.
The adaptor is formed to have a centrally disposed radial aperture 28. An extension 30 with external threads 32 is formed to extend radially from one side of the adaptor. The adaptor is also provided with a rotatable ball-shaped valve 34. Such valve is coupled to an external handle 36 for adjustment purposes at the discretion of the user. The valve has a T-shaped opening with an enlarged central diametric opening 38. It is also formed with a smaller radial opening 40. The openings join together adjacent to a central region of the ball-shaped valve. The handle is adapted to position the valve in any one of a plurality of orientations as shown in FIG. 6. FIG. 6 shows the diametric opening in alignment with the opening through the adaptor for the flow of water to the shower head. The smaller radial opening is in alignment with the opening through the extension. In this manner, a flow of water is concurrently directed to the person showering as well as to the toothbrush of the person brushing his or her teeth as will be later described. Upon using to turn the handle 180 degrees from the orientation shown in FIG. 6, the flow of water will be to the shower head to the exclusion of the toothbrush. By turning the handle 90 degrees clockwise the flow of water will be to the toothbrush to the exclusion of the shower head. By turning the handle counter-clockwise 90 degrees no water will flow to the shower head or to the toothbrush. It should be understood that varying the handle and ball-valve to various degrees between these three major orientations as described above, different degrees of water may be directed concurrently to the shower and to the toothbrush in varying amounts as intended by a user.
The next major component of the system 10 is a toothbrush 44. The toothbrush has a far end 46. At the far end are outwardly extending bristles 48. The toothbrush also has a near end 50. The near end is formed with a rectilinear or box-like shape constituting a female connector. In association therewith there are a pair of parallel lines 52,54 extending along the length of the toothbrush in the area of the handle 56. A plurality of small apertures 58 are formed adjacent to the bristles near the far end. This is at a location at the internally terminal ends of the lines. The lines and apertures together allow for the dissemination of water from the lines through the apertures to the mouth and teeth of the person brushing his or her teeth.
Associated with the toothbrush 44 is a water release button 84. The water release button 84 is positioned intermediate end portions of the pair of parallel lines 52,54. The water release button 84 has an upper end 86 extending outwardly of the toothbrush 44. A lower end 88 of the water release button 84 has a pair of springs 90 disposed thereon. The water release button 84 further has a pair of horizontally disposed apertures 92 therethrough. The water release button 84 can be pressed down into the toothbrush 44 thereby allowing the apertures 92 to align with the pair of parallel lines 52,54 to allow for water to flow therethrough to the plurality of apertures 58 for dissemination outwardly thereof. A pair of protrusions (not shown) on the sides of the water release button 84 will engage a pair of recesses (not shown) within the toothbrush 44 to lock the release button 84 in a water flow orientation. Pressing downwardly on the water release button 84 again, will cause the protrusions to release from the recesses to disengage the water release button 84 thereby misaligning the apertures 92 from the pair of parallel lines 52,54 to stop the flow of water.
Lastly provided as part of the system 10 is a flexible hose 62. Such hose is provided with an upper end 64. The upper end is formed with a fitting 66. The fitting is formed with internal threads 68 for coupling with the threads of the extension of the adapter. The hose also has a lower end 70 in a rectilinear or box-like shape or configuration. Such lower end is for receiving the near end of the toothbrush.
The lower end of the hose has an annular recess 74. An associated O-ring is located within the annular recess. The function of the O-ring is to make a watertight seal between the toothbrush and the lower end of the hose during operation and use.
The toothbrush is also formed to have a radially outstanding flange 78. Such flange is adapted to be received in a complementary radial recess 80 in the lower end of the hose. This is to insure the coupling between the hose and the toothbrush during operation and use.
The present invention comprises a toothbrush that utilizes the water force delivered by a typical bathroom sink or shower. It is made from plastic and rubber, and consists of a handle, a detachable head, a disposable brush, a plastic or rubber hose, and a water switch valve. The handle has two parallel water channels running longitudinally along its full length with their inlet openings in the handle's bottom. Six water outlets project perpendicular from each channel in the head area. The head can be removed and replaced with a different one, enabling the toothbrush to be used by different family members. The brush slides in and out of a longitudinal track situated on the head. Fastened to the bottom is a hose containing two tubes. The hose's other end attaches to an outlet with a switch valve that is situated in the water line just prior to a faucet or shower head. The brush could be made as part of a kit that includes a shower holster for toothpaste, a water cup, and replacement heads.
To use, apply toothpaste to the brush, fasten the hose to an appropriately equipped bathroom water line, turn on the switch valve, and brush. The water also sprays around the teeth while brushing. The present invention enables one to utilize the water pressure from a sink or bathtub shower to clean the teeth, which should be less messy and save time.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
