DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the issued claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
Turning now to FIG. 1, there is shown a pick 32 and brush 34 formed on a shaft 30 that may be placed at the end of a handle as further shown and described in FIG. 4. The shaft 30 is shown with one side having two opposing scoops 36 and 38 that narrow and come to a point at pick 32. Pick 32 preferably is sized to fit between the gap in teeth to facilitate removal of plaque or tartar that forms on the teeth and in the crevices between teeth. As plaque or tartar is scraped off a tooth, it may collect on the scoops 36 or 38 for later removal. Scoops 36 and 38 are formed in a half tetrahedral separated by a central ridge.
Brush 34 is an extension of blade 42 that is formed at the conjunction of scoops 36 and 38 and bottom 40. Pick 32 has a sharp end that is upturned to help in scraping and pulling plaque or tartar from between the teeth. Brush 34 is formed at the end of blade 43 and fits between teeth to further help in the removal of plaque that has been scraped or dislodged by pick 32.
In operation, pick 32 may be used both on the front surface of teeth or on the back surface to remove plaque and collect it in concave scoops 36 and 38. Brush 34 further enhances the removal of dislodged or loose plaque, tartar or other debris. FIG. 2 shows in side view of shaft 30 with pick 32 and brush 34 extended therefrom. Shaft 30, pick 32, and brush 34 may all be manufactured in any of a variety of materials including plastic, stainless steel, or other composites. Brush 34 may be cut or machined integrally with the shaft 30 or be appended as a separate item after manufacture of pick 32, concave scoops 36 and 38, bottom 40 and blade 42.
FIG. 3 shows shaft 30 in end plan view with scoops 36 and 38 and pick 32 at the end of shaft 30. Brush 34 is shown extended from the blade of pick 32 with bottom rounded portion 40 on the opposite side of tetrahedral side formed by scoops 36 and 38.
FIG. 4 shows a two ended handle 10 with needle 24 connected to end 22, mounted on tube 20, connected to hub 14 and handle center 12. On the opposite side of needle 24 is positioned second hub 14, tube 16 terminating in spoon 18. As is readily apparent, shaft 30 of FIGS. 1 through 3 may be attached to tube 20 to become part of the two ended handle 10. Two ended handle 10 provides a convenient and ergonomic way to manipulate each end of the handle in the mouth for dental care. Spoon 18 is further described below in FIGS. 7A and 7B.
Handle Center 12 may be smooth or configured with a variety of textures for easy grip. FIG. 5A shows a herringbone patter, FIG. 5B shows a checkerboard pattern, and FIG. 5C shows concentric ring grips. Other gripping patterns well known in the art may be employed as well as an additional wrap of rubber or other tacky material. FIGS. 6A, B and C show in cross sectional view handle center 12 in a variety of configurations including octagonal in FIG. 6A, hexagonal in FIG. 6B, and circular in FIG. 6C. Again, any of a variety of cross sectional shapes may be employed and still be within the spirit of the invention.
FIG. 7A shows spoon 18 as an extended spoon shape with elongated concavity. Spoon 19, an alternative design, shows an extended spoon with a generally circular and deeper concavity than spoon 18. Each is designed as one mechanism for scraping and removal of plaque or tartar from the teeth. By using a spoon, the user may reach around the edges of each tooth and cup the tooth closely in such a way as to scrape and remove debris. The spoon also permits reaching behind the teeth for removal.
FIGS. 8A and 8B shows an alternative pointed end to the dental tool of the present invention. Wedge 50 terminates with needle extension 52 for insertion between teeth of the end portion of wedge 50. Needle extension 52 as shown close up in FIG. 8B has a pointed end 54 that serves as a kind of toothpick to go between the teeth and dislodge debris. Needle extension 52 is configured to be of a size that can fit between the gaps in teeth and scrape away plaque or tarter between the teeth.
FIGS. 9A through 9D show an alternative extension of shaft 60. FIG. 9A is a plan view of extension 62, with FIG. 9B showing an elevation view that depicts a pointed needle end of extension 62. FIG. 9C shows a side view of extension 62, whereas FIG. 9D shows a perspective view of extension 62. As is readily apparent, extension 62 is configured to provide access to the spaces between teeth for scraping and removing debris.
FIG. 10 shows an end of a dental too with scoop 72 angled at angle theta 75. Theta 75 may be of any of a variety of angles to facilitate reaching behind the teeth for removal of debris. Preferably angle theta 75 should be approximately 30-35 degrees.
FIG. 11 shows dental tool similar to FIG. 1 having a pick 32 formed on a shaft 30 that may be placed at the end of a handle as further shown and described in FIG. 4. The shaft is shown with one side having two opposing scoops 36 and 38 that narrow and come to a point at pick 32. Pick 32 preferably is sized to fit between the gap in teeth to facilitate removal of plaque or tartar that forms on the teeth and in the crevices between teeth. As plaque or tartar is scraped off a tooth, it may collect on the scoops 36 or 38 for later removal. FIG. 11 as an alternative embodiment has brush 34 positioned on the ridge connecting scoops 36 and 38, positioned just behind pick 32. While blade 42 is pushed between teeth, brush 34 acts to dislodge and remove debris along its length.
FIG. 12 shows a dental tool similar to FIG. 11 having two opposite sides with scoops 36A and 38A, and opposite side having scoop 38B next to reciprocal scoop to 36A not shown. Picks 32A and 32B are on each end of blade 42 formed at the end of shaft 30. Shaft 30 is shown with two opposing scoops 36A and 38B that narrow and come to a point at pick 32. On the opposite side, are mirror images of scoops 36A and 38A. As plaque or tartar is scraped off a tooth, it may collect on the any of the scoops for later removal. FIG. 12 has upper brush 34A positioned on the ridge connecting scoops 36A and 38A, positioned just behind pick 32A. On the bottom side of shaft 30, brush 34B is similarly positioned between the two scoops positioned just behind pick 32B. In one embodiment, the cross sectional shape of the opposing tetrahedral sides would resemble a 4-sided diamond shape with curved inward sides.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the issued claims.
