EENACRE PATENT AGENTS DENTAL CARE APPLIANCE This invention relates to new and useful improvements in dental care appliances, and in particular the invention concerns itself with a tooth flosser of the general type which includes an elongated handle having a bifurcated head at one end thereof, the head including a pair of spaced arms provided in their extremities with notches so that a length of dental floss inserted in the notches and stretched between the arms may be used for cleaning spaces between teeth in a convenient and efi'ective manner.
The principal object of the invention is to provide a tooth flosser of this general type with novel and improved means for anchoring the length of floss when it is tensioned between the spaced arms of the head, the improved anchoring means consisting of a button which is slidably positioned in an opening in the head and is formed with passages to receive the floss so that when the button is slid in one direction in the opening, the floss is securely anchored in its tensioned condition.
. Another important object of the invention is to provide a tooth flosser of the aforementioned type with a plurality of selectively usable attachments for auxiliary dental care, such as a brush, mirror, and the like, these various attachments being removably applicable to the outer end of the handle, remote from the flosser head, so that they are readily available for use.
Some of the advantages of the invention residein'its simplicity of construction, efiicient operation, and in its adaptability to convenient and economical manufacture.

the invention is designated generally by the reference numeral 10 and comprisesan elongated handle 12 which is provided integrally at one end thereof with a bifurcated head 13, including a pair of spaced divergent arms 14. Preferably, the head 13 is disposed in a plane which is offset by an acute angle from the plane of the handle, as shown in FIG. 2. The free extremities of the arms 14 are formed with notches 15 in which a length of dental floos may be inserted and stretched between the arms for convenient cleaning'of spaces between teeth in the well known manner.
The invention primarily concerns itself with the provision of improved means for anchoring the floss in its stretched or ten sioned condition. Such means comprise a floss anchoring button generally designated as 16 which is slidably disposed in an opening 17 formed in the head 13, as detailed in FIGS. 3-6.
The anchoring button 16 comprises a shank 18 provided at its opposite ends with enlarged knobs 19, 20. The shank 18 and the opening 17 in the head 13 are of a complemental, noncireular cross-section, in order to prevent rotation of the shank in the opening. As shown in FIG. 5, such a cross-section may be that of a flat-sided oval, although other configurations may be used. The heads 19, 20 may be shaped to correspond to the cross-section of the shank.
The length of the shank 18 is greater than the thickness of the head 13 so that the shank is slidable in the opening 17 within limits where either of the knobs 19, 20 engages the adjacent side surface of the head. In FIGS. 3 and 4 the button 16 is shown as being slid downwardly so that the upper knob 19 abuts the upper surface of the head 13, but the button may be slid upwardly so that the knob 20 abuts the underside of the head.
For purposes of receiving and anchoring the floss, the button 16 is provided with passages including a kerf 21 which extends through the knob 19 into the adjacent portion of the shank l8 and a pair of grooves 22 which are formed in the rounded ends of the flat-oval crosssection of the shank, as will be apparent from the drawings.
In use, a length of dental floss is placed in the notches 15 of the arms 14 and stretched between the arms, while the end portions of the floss are brought to the button 16. The button is slid upwardly in the head 13 (from the downwardly slid position of FIGS. 3 and 4) so that the portion of the button with anchoring the floss in its tensioned condition.
The handle 12 of the tooth flosser is longitudinally tapered and its outer end portion 12a is adapted to selectively accommodate a wide variety of auxiliary attachments for dental care, as presently described.
One of such attachments is a tooth brush shown inFIGS. 7 and 8. The same comprises an elongated body 23 provided with an elongated and longitudinally tapered socket 24, the major end of the socket being open so that the body 23 may be slidably applied to and frictionally held in position on the tapered end portion 12a of the handle. The body 23 carries tufts of bristles 25.
FIGS. 9 and 10 show another attachment in the form of a .tooth wiper, wherein the body 23 is provided with a covering 26 of cloth or sponge. In FIGS. 11 and 12 the tooth wiper is modified for cleaning inner tooth surfaces, the body 230 in this instance having a curved end portion on which the sponge or cloth element 26a is mounted.
FIGS. 13 and 14 show a sub-bridge cleaning attachment in which the body 23 carries a prong 27 with a notched end for guiding floss underneath the pontic of a bridge.
FIGS. 15 and 16 show a mirror attachment in which the body 23b has an angularly offset portion carrying a mirror 28.
FIGS. 17 and 18 show another attachment wherein the body 23 is provided with a flexible rubber cup 29 for tooth cleaning purposes.
in FIG. 19 the body 23 carries a gingival crevice cleaning element 30 which may be either straight or longitudinally curved. in FIG. 20 the body 23 is equipped with an interproximal brush 3l.
in all these various attachments the attachment body is frictionally held in position on the handle by insertion of the tapered handle end portion 124 into the socket 24 in the body, as already mentioned. if desired. such frictional mounting may be enhanced by forming the handle end portion 12a with a longitudinal channel 32 as shown in FIG. 22, and providing a longitudinal rib 33 in the socket 24 of the body 23 as shown in FIG. 23, so that the rib 33 is slidably but frictionally received in the channel 32 when the attachment body 23 is applied to the handle end portion 12a as in FIG. 21.
FIGS. 24 and illustrate a modified arrangement for removably mounting the attachments on the handle. Here the attachment has an elongated body 34 which is adapted to be superposed on the handle end portion 12a and is provided at the underside thereof with a pair of tapered studs 35. The handle end portion 124 is formed with a pair of tapered apertures 36 in which the tapered studs 35 are frictionally received to removably hold the attachment on the handle. it will be understood that while the attachment body 34 in FIGS. 24 and .25 is shown as carrying a wiper element 3'7, the mounting means 35, 36 may be used in any or all of the various types of attachments as shown in FIGS. 7-20 inclusive.
While in the foregoing there have been described and shown the preferred embodiments of the invention, various modifications and equivalents may be resorted to within the spirit and scope of the invention as claimed.
