Description

TITLE OF THE INVENT'tON
DENTAL PLOSSER
FIELD OF THE INVENTION
The present invention is related to dental care products and, more particularly, to a L-shaped dental flosser which is changeable from a 2-Dimension construction to a 3-Dimension construction.
i3ACK(xROUND OF RELATED ART
As a dental hygiene tool, a dental flosser used for removing plaque and debris from between teeth is essentially comprised of a U-shaped holder defined by a pair of fingers or tines which hold a section of dental floss material there 1 s between; and a handle having its distal end connected and secured to the bottom of the U~shaped holder. Depending on the fashion of connection between the handle and the U-shaped holder, dental flossers having already been disclosed are divided into two types. Type 1 relates to a 2-t)imension dental flosser with its U-shaped holder and the handle located on the same plane, and the floss and 2 o the handle are also located on the same plane, as represented by US Patent US5692531. Advantages of 2-Dimension dental flossers include easy portability since they are flab and comparatively lower production cost.
Defective about the 2 Dimension dental flosser is that it is difficult to access certain interdental spaces when employed to clean tile back teeth since the floss 2 5 IS hard to parallel with the direction of the arrangement of slits between those teeth, thus impacting the cleaning results. Type 2 relates to a 3~Dimension dental flosser having its U-shaped holder and the handle in L-shaped construction (3-Dimension construction), i.e., not on the same plane; and the floss is vertical to the central axis of the handle as represented by US Patent 3 o US5388600. The 3-D imension dental flossers provide advantage that the floss _1_ .._.w >p..,. .,.. ~k.Y ~,..d~... .x~, .NaW., .~q6YG4Y;:.,..,LM~y.x..2zRtfaV~x.....<;.G.W~FG~e x.kRn, >_~:..: 'i2,., :' ,..Ae ..t".. _ne.!~xro...

That is, it could actually access any interspaces between teeth for getting substantially thorough cleaning results. However, the L shaped dental flosser needs comparatively larger space for packaging and carrying, and costs more.
s In general, Dimension dental flosser allows easier packaging and portability, and lower manufacturing cost; but it fails thorough cleaning results for back teeth.
On the contrary, L~haped dental flosser provides comparatively thorough cleaning results for the back teeth, but not so convenient for packaging and portability white its production cost is comparatively higher.
to SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide an Lshaped dental flosser that achieves comparatively thorough cleaning results while 15 permitting easy packaging and portability, and lower production cost.
To achieve the purpose, a L-shaped dental flasser in 2-Dimension construction is comprised of a U-shaped holder 22, a section of dental floss secured and bridged between both tines of the U-shaped holder, and a left and a right handles 31, 32 respectively connected to the bottom of the U~haped holder.
a o Wherein, both distal ends from the left and the right handles 31, 32 are respectively connected to t~th sides at the bottom of the U-shaped holder, and a left hinge and a right hinge 41, 42 are respectively provided thereon. Both of the left and the right hinges 41, 42 are made thinner and allow easy bending so to permit both of the left and the right handles 31, 32 to respectively tum around the a s left and the right hinges 41, 42 to close in and contact each other. A
left locking means 31a and a right locking means 32a may be respectively provided to the left and the right handles 31, 32 for both of the left and the right handles to be tightly interlocked to each other. Both surfaces respectively from the left and the right handles 31, 32 are disposed with multiple ribs to increase the surface friction thereon. To make the present invention even more compact, both distal ends of the left and the right handles 31, 32 are connected to each other and a thinner and allowing easy bending tail hinge 51 is provided at where the connection takes place.
s In its non-use status of the present invention, the llshaped holder 22 and both of the left and the right handles 31, 32 are located on the same plane to indicate a 2-Dimension construction. When in use, both of the left and the right handles 31, 32 are respectively turned around the left and the right hinges 41, 42 to close onto each other until their distal ends are in congruous status.
1 o Meanwhile, both of the left and the right handles, and the Ushaped holder indicate a 3-Dimension L-shaped construction. The user is allowed to use the dental flosser by merely holding both of the left and the right handles 31, 32 to operate the floss 11 secured and bridged between both distal ends of the U-shaped holder. With the use of hinges for the connection, both of the left and 15 the right handles 31, 32 are able to respectively turn around the left and the right hinges 41, 42 to close in and contact each other thus for the present invention to shift between 2-Dimension plane and 3-Dimension L-shaped constructions.
That is, when the present invention is in its non-use status, it indicates a plane 2-Dimension construction; and when in use, it indicates a 3-Dimension L-shaped 2 o construction. As a result, the present invention provides the advantages including easy packaging and portability, lower production cost found with the 2-Dimension dental flosser and comparatively more thorough cleaning results since it is capable of being changed to a 3-Dimension L~haped dental flosser when in use.
2 5 A left locking means 31 a and a right locking means 32a are respectively disposed to both of the left and the right handles 31, 32 to tightly interlock both of the left and the right handles 31, 32 to each other for providing an even stable use of the present invention. Multiple ribs 3b are provided on each surface of the left and the right handles 31, 32 to increase friction thereon for a firm holding of the _g_ a. r . ,_, . . ~..x -. rr,. . .w . , . , 3,,.. ~~ " ,..,~;. .t.~,,~ . :wx v~r F~.~.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
a s Referring to Fig. 1 for a schematic view of a construction of a 2-Dimension dental flosser of the prior art, it is comprised of a U-ehaped holder 22 defined by a pair of fingers or tines which hold a section of dental floss material 11 there between; and a handle 33 with its front end connected and secured to the bottom of the U-shaped holder 22. Both of the U-shaped holder and the handle 33 are _ 5_ located on the same plane while both of the floss 11 and the handle 33 are also located on the same plane. Since both of the U-shaped holder 22 and the handle 33 are located on the same plane, the Dimension dental flosser provides advantages of easy packaging and portability, and lower manufacturing cost; however, the cleaning results of the 2-Dimension dental flosser is compromised by that it is difficult to access the back teeth owing to the floss 11 is not in parallel with the direction of the arrangement of the slits between those teeth.
Fig. 2 shows a schematic view of a construction of a 3-Dimension 1 o L-shaped dental flosser of the prior art. It is essentially comprised of a U-shaped holder 22 with its both tines holding a section of dental floss material 11 there between; and a handle 33 having its front end connected and fixed securely to the bottom of the U-shaped holder 22. The relation between the U-shaped holder 22 and the handle 33 indicates an L-shaped consfivction and is is not on the same plane. The floss 11 is vertical to l:he central axis of the handle 33. The L-shaped dental flosser provides the advantage of comparatively more thorough Leaning results since the floss is capable of reaching any interspaces between teeth. However, the flaws of the L-shaped dental flosser include higher manufacturing cost, and difficult packaging and portability-since it occupies a o larger space.
As illustrated in Fig. 3, a first preferred embodiment of the present invention in its non-use status is comprised of a U-shaped holder 22 with its both tines holding a section of dental floss material 11 there between a left handle 31, and a right handle 32 with both handles 31, 32 respectively connected to the bottom 2 5 Of the U~shaped holder 22. Wherein, both front ends of the left handle 31 and the rift handle 32 are respectively connected to both sides at the bottom of the U-shaped holder 22, and a left hinge 41 and a rigYit hinge 42 are respectively disposed at where both handles 31, 32 are connected to both sides at the bottom of the U-shaped holder. Both of the left and the right.hinges 41, 42 are made thinner and easier to be bent so to allow both of the left and the right handles 31, 32 to respectively tum around on the left and the right hinges 41, and to get closer to contact each other.
Furthermore, a left locking means 31 a is provided at the distal end of the left handle 31. The left locking means 31a includes a ball, and a narrower and thinner band connecting the ball. Another end of the band is connected to the distal end of the bft handle 31. Meanwhile, a right locking means 32a is disposed to the right handle 32. The right locking means 32a includes a round hole, and a gap is provided at the front edge of the round hole. The diameter of io the round hole of the right locking means 32a is slightly smaller than that of the ball 31a.
It should be appredated that other types of the locking means can be used as long as a set of proper locking means is divided into two matching parts to be respectively disposed at where appropriately on the left and the right handles 31, 32 and both matching parts are able to be locked to each other thus to tightly fasten both of the left and the right handles 31, 32 for use.
Multiple ribs 3b are disposed on the surfaces of the left and the right handles 31, 32 to increase the friction thereon. As a result, the user of the present invention could firmly hold both of the left and the right handles 31, 32 in cleaning 2 o hislher teeth.
A tiny and sharp tail is disposed at the distal end of the right handle 32 to function as a toothpick or gum stimulator.
As illustrated in Fig. 3, when the first preferred embodiment is not in use, all the U-shaped holder 22, both of the left and the right handles 31, 32, and both locking means 31a, 32a are located on the :;ame plane to indicate a 2-Dimension construction to provide the advantages of easy padkaging and portability, and lower manufacturing cost as that given by the 2-Dimension dental flosser of the prior art Fig. 4 shows the first preferred embodiment in use.

Apply force to press the ball of the left locking means 31a into the round hole of the right locking means 32a to interlock both of the left and the right locking means 31 a, 32a, and thus both of the left and the right handles 31, 32. When both of the left and the right handles 31; 32 are interlocked to each other, the left handle 31, the right handle 32, and the U-shaped holder 22 indicate an L shaped construction. The user merely holds both of the left and the right handles 31, 32 to operate the flass 11 bridged i o between both ti nes of the U~haped holder to Gean her/his teeth. The first preferred embodiment in use appears to provide the advantage found with the 3-Demension L-shaped dental flosser that is capable of accessing any interdental spaces to facilitate comparatively more thorough leaning results.
In the first preferred embodiment of the present invention, it is characterized i 5 by the construction of dual handles 31, 32 and the connection means provided by both living hinges 41, 42 for the first preferred embodiment to make shifts between 2 Demension and 3-Demension constructions of the dental flosser. In its non-use status, the first preferred embodiment indicates a ~Demension construction, and in use status a 3~Demension construction. As a result, the 2 o present invention provides the advantages of the 2-Demension and the 3-Demension dental flossers at the same time.
Generally, either in location or direction, both of the left and the right hinges 41, 42 are arranged in symmetric in relation to the central axis of the llshaped holder 22. However, a controlled asymmetric arrangement is permitted. Given a s with the symmetric arrangement, an included angle defined by the left hinge 31 and the central axis of the left handle 31 is aqua! to that defined by the right hinge 42 and the central axis of the right handle 32. The included angle is a very important technical index since it directly determine the included angle defined by the U-shaped holder and both of the left and the right handles 31, 32.

Fig. 5 shows a second preferred embodiment of the present invention in its non-use status. When compared to the first preferred embodiment, the second preferred embodiment essentially differs in the following aspects:
( 1 ) In temps of the relation with the U-shaped holder 22, both of the left and the right handles 31, 32 of the second preferred embodiment are different from that of the first preferred embodiment either in location or direction. In practice, io the present invention allows quite a great range of changes for the location and direction of both of the left and the right handles 31, 32, and that permits more options for the manufacturers in the design of the appearance of a dental flosser as desired.
(2) Both of the included angles respectively defined by the left hinge 41 and the central axis of the left handle 31, as well as by the right hinge 42 and the central axis of the right handle 32 are also different from those found with the first preferred embodiment. In practice, the present invention permits a wider range of changes for the included angle.
(3) Both of the left and the right hinges 41, 42 are not in parallel with each 2 0 other in the second preferred embodiment. Accordingly, a torque developed when both of the left and the right handles 31, 32 are closing on each other will affect smooth use of the present invention. To solve this problem, a triangular area 41a closer to the vicinity of the left hinge 41 and another triangle area 42a closer to the vicinity of the right hinge 42 are made thinner for both triangular a s areas 41a, 42a to properly twist when subject to force applied when both of the left and the right handles 41, 42 are closing on each other, thus to reduce the torque applied upon both of the left and the right handles 31, 32.
(4) Both of the left and the right locking means 31a, 32a are omitted in the second preferred embodiment to permit simple construction.

Fig. 7 shows a third prefer-ed embodiment of the present invention in its non-use status. When compared to the second preferred embodiment, the third s preferred embodiment essentially differs in that both distal ends respectively from the left and the right handles 31, 32 are connected to each other and a hinge which is thinner and allowing easier bending is provided at the connection;
that the shape respectively of the left and the right handles 31, 32 is different from that found with the second preferred embodiment; and that an rear area 31d and i o another rear area 32d are respectively provided to the left and the right handles 31, 32. Both of the rear areas 31d, 32d are made thinner to allow easy twist to facilitate closing on each other in use.
As illustrated in Fig. 8 when the thi rd preferred embodiment is in use, both of the left and the right handles 31, 32 as well as both the rear areas 31d, 32d i5 respectively of the left and the right handles 31, 32 are laterally pressed for them to respectively tum around the left hinge 41, the right hinge 42, and the tail hinge 51 until both rear areas 31 d, 32d are closing on each other. The user merely holds both of the left and the right handles 31, 32 as well as both rear areas 31d, 32d to operate the dental flosser of the present invention. When compared to a o the second preferred embodiment, the third preferred embodiments features more compact construction, and easier operation of both handles.
Fig. 9 shows a fourth preferred embodiment of the present invention in its non-use status. When compared to the third preferred embodiment, the fourth preferred embodiment is essentially improved in that: a left locking means 31a is 2 5 disposed to the rear area 31 d of the left handle 31, and a right locking means 32a is disposed to the rear area 31 d of the left handle 31. In use, press the ball adapted to the right locking means 32a into the round hole dispose! at the left locking means 31a. As a result, both of the left and the right locking means 31a, 32a are interlocked to each other, thus both of the rear areas 31 d and 32d are -~. o-..., , ..., ..s dAr. -..:W:SA a arYVC , aF~FYkyCC..zs'':.TS3Y:
