With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved dental flosser apparatus embodying the principles and concepts of the present invention and generally designated by the reference numerals 10 and 10a will be described.
More specifically, the dental flosser apparatus 10 of the instant invention essentially comprises a generally U-shaped frame portion 11, having respective first and second parallel and coextensive legs 12 and 13 respectively extending from a frame base 14, wherein an arcuate abutment bar 15 is orthogonally mounted to the first and second legs 12 and 13 extending above the first and second legs in an orthogonal relationship. Respective first and second U-shaped cradle bars 16 and 17 extend below the U-shaped frame portion 11 between the frame portion base 14 and the arcuate abutment bar 15 to receive and secure a floss dispenser housing 18 within the first and second U-shaped cradle bars 16 and 17 that is arranged to extend above and below the U-shaped frame portion 11 for abutment with the abutment bar 15, wherein an outlet opening 19 directs a dental floss filament 24 through the arcuate abutment bar 15, in a manner as illustrated in FIG. 2 for example. A first cross bar 20 extends orthogonally between the first and second legs 12 and 13 beyond the floss dispenser housing 18 and the abutment bar 15, with a rotary guide post 21 rotatably and orthogonally directed through the first cross bar 20, having a knurled cylindrical wall portion 22 oriented below the first cross bar 20 and an annular groove 23 received within an uppermost portion of the rotary guide post 21 to direct and receive the filament 24 therewithin, with a second cross bar 25 spaced from and parallel the first cross bar extending orthogonally between the first and second legs 12 and 13 to provide and impart geometric integrity to the organization, as a first guide post 26 extends orthogonally above the first leg 12 at its intersection with the second cross bar 25, and a second guide post 28 extends orthogonally below the second leg 13 at its intersection with the second cross bar 25. The first guide post 26 includes a first boer 27, with the second guide post 28 having a second bore 29, with the first and second bores 27 and 29 arranged in a parallel spaced relationship relative to one another to receive the filament therethrough as the first bore 27 receives the filament from the annular groove 23, as indicated in FIG. 2 for example. Respective first and second extension legs 30 and 31 are arranged to project colinearly from the first and second legs 12 and 13 and project below the first and second legs 12 and 13, with the first extension leg 30 having a first extension leg aperture, and the second extension leg 31 having a second extension leg aperture, with the first and second apertures oriented orthogonally relative to the first and second bores 27 and 29. In this manner, the filament is directed from the first bore 27 through the first and second apertures 32 and 33 and then is directed through the second bore 29 to be wound about the knurled cylindrical wall portion 22 as a take-up roll to receive and direct the dental floss filament thereabout as it is taken up from the dispenser housing 18.
The FIGS. 5 and 6 indicate a modified apparatus 10a, wherein the first and second legs 12 and 13 are discontinuous, with a first disc 34 fixedly mounted in an orthogonal relationship relative to the first and second legs between the first and second cross bars 20 and 25, with the use of a second disc 35 fixedly and orthogonally mounted to the first and second legs 12 and 13 in adjacency to the second cross bar 25, as the first disc 34 is oriented in facing relationship relative to the first cross bar 20 such that a disc axle 36 rotatably secures the first and second discs 34 and 35 together maintaining the first and second discs in any desired angular orientation relative to one another by a disc friction ring 37 (see FIG. 6) interposed between the first and second discs 34 and 35, as indicated in FIG. 6.
The FIGS. 7 and 8 indicate a further modification of the second extension leg 31, wherein a second extension leg pivot axle joint 38 includes an axle wheel 39 to permit rotation and displacement of the second aperture 33 relative to the first aperture 32 for providing enhanced adaptability of the structure in a dental flossing procedure.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall 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.
