Except for the method as shown in FIG. 4, there remain some other methods for quick mounting the dental floss 40 on the holding member 30 in order to meet the purpose of quick replacement. Referring to FIGS. 6 and 7 a groove 34 can be cut in the center of the 5 hook-shaped portion 33 in parallel to the holding member 30 for the dental floss and both ends of the dental floss 40 can be respectively secured together with a stationary member 42 resembling a solid block (as FIG. 8) for hooking the two stationary members 42 into the 10 portion 33 so that the dental floss 40 will enter the groove 34 and therefore the dental floss 40 is secured thereof.
In order to secure the holding member 30 for the dental floss the holder 10 has a locating member 20 IS thereon for locating the holding member 30 at different angles of inclination as shown in FIGS. 3 and 4. The locating member 20 of this invention includes two stop blocks 24 which angularly arranged and located at the leading end of the stem 12 and a slide buckle 21 slidably 20 cased at the rear side of the stop blocks 24 on the stem 12. Wherein the leading end of the slide buckle 21 has two mutually inclined bevels 23 which are fitted the stop blocks 24 each other, and a groove 22 which can be set in together with the handle 31 at the final end of the 25 holding member 30 for securing the holding member 30 at a parallel position to the holder 10. When the floss head 30 is desired for a angle of inclination the user may push the slide buckle 21 backward with the thumb to cause the groove 22 disengaging with the handle 31 of 30 the holding member 30 so that the holding member 30 can swing left-handed and right-handed; when the holding member 30 is turned left-handed or right-handed at an angle of inclination and the slide buckle 21 is pushed forward with the thumb to cause the bevel 23 pushing 35 the handle 31 tightly against the stop blocks 24 whereby the holding member 30 for the dental floss can be located left-handed or right-handed at an angle of inclination.
In order to get the slide buckle 21 thoroughly secured 40 to the holding member 30 there is a stop member 25 mounted on the stem 12 for preventing the slide buckle 21 from sliding backward as shown in FIGS. 2,3 and 4. The stop member 25 is slidably cased on the stem 12 and located at the rear side of the slide buckle 21. The lead- 45 ing end of the stop member 25 has a reducing end 26 and the rear end on the inner hole of the slide buckle 21 has an expanding end 27. When the slide buckle 21 is pushed forward for securing the holding member 30 the stop member 25 can be pushed forward with the thumb for 50 inserting its reducing end 26 into the expanding end 27 at the rear end of the slide buckle 21 whereby the slide buckle 21 is secured. When the stop member is pushed backward to cause the reducing end 26 disengaging with the expanding end 27 of the slide buckle 21 55
whereby the slide buckle 21 can be released backward. In addition there remain some other methods for securing the slide buckle 21 as shown in FIGS. 9 and 10 wherein the slide buckle 21 will be limited to slide as a result of reducing its space between with the stem 12, or when in use the user may hold back the slide buckle 21 with the fingers in order to meet the purpose of effectively securing the slide buckle 21 to the holding member 30 for the dental member 30.
The advantages of this invention for use include: (1) the holding member for the dental floss is operative to clean up the deep portion in the cavity of the mouth with the design of change in the angles (2) dental floss can be disposed after use without necessity of disposing the whole device so as to minimize the waste.
What is claimed is:
1. A dental floss holder comprising:
a) a holder portion defining a chamber for storing dental floss therein;
b) a locating member attached to and extending from an end of the holder portion, the location member having a distal end portion;
c) a generally "U"-shaped dental floss holding member having a pair of legs adapted to removably attach thereto a segment of dental floss such that the dental floss extends between the pair of legs and a locking pin extending outwardly from one of the pair of legs;
d) attaching means to permanently attach the dental floss holding member to the distal end of the locating member such that the dental floss holding member may pivot with respect to the locating member;
e) a plurality of stop blocks located adjacent to the distal end of the locating member; and,
0 a slide member slidably attached to the locating member so as to be movable between a first position wherein the dental floss holding member is pivotable with respect to the locating member and a second position wherein the locking pin is held between a stop block and the slide member so as to hold the dental floss holding member stationary with respect to the locating member.
2. The dental floss holder of claim 1 further comprising at least one groove defined by the slide member and adapted to receive therein the locking pin when the slide member is in its second position.
3. The dental floss holder of claim 1 wherein each of the pair of legs has a generally hook-shaped end portion adapted to engage elements on a dental floss segment so as to releasably attach the dental floss segment to the dental floss holding member.
4. The dental floss holder of claim 1 wherein each of the pair of legs has an end portion defining slot adapted to receive therein an end of a dental floss segment.
