Interdental brush

[Detailed Description of the Invention]

[Industrial Application] the present invention can be removed -- twisting -- A wire brush and a brush .. it is related with the brush between teeth provided with Rundle. Yo Si -- it Take upsilon removes and, specifically, the present invention is possible -- twisting and having a wire brush and a brush handle Expansion power 2 in which a brush is provided with the details which molded the plastic enclosure part into the circumference, and the above-mentioned plastic enclosure part is located between an anchor axis part and the above-mentioned brush - It has a holding portion located below the color, and the brush handle is aimed at the brush between teeth which has a hole of the above-mentioned plastic collar and the internal shape where it corresponded to the outside of the anchor axis part partially at least. [Description of the Prior Art] It becomes United States patent pipe No. 4.222.143 as [ use / the present invention ], and an example of a fill (replacement type) brush is an example. K Where it twisted the brush handle between teeth given in this patent and a wire brush is projected to the method of outside, Acceptance has become as [ put ]. Such a brush is used for brushing of the crevice between teeth, or the portion of the neighborhood. For example, a brush is used in order to sanctify the crevice below the tooth bridge in the inner part of a mouth. When using such a Ri fill brush for a handle, equipping with it, there are many problems. People with the high necessity of sanctifying the field below a tooth bridge are an old man and a person with trouble in movement of a hand in many cases. For such people, it is very troublesome to operate small parts. If a metal zipper is used in order to hold a wire brush, a book will twist and the problem of it becoming impossible for a crack and crease music Si to arise and use it for a wire axis part will also arise. The problem of operativity will become large, if the whole uses the zipper made in the plastic in order to hold a brush. Also in any of an above-mentioned structure or a structure similar to them, if it is not operated to predetermined Procedure DK prudence, there is a problem that the holding state of the brush by a zipper loosens. When slack arises, a user requires a possibility that problems, such as poking Si who cannot control movement of a brush, the evening which damaged the dental enamel layer, and the gum, may arise. [Problem(s) to be Solved by the Invention] The efforts for K Carrying out for the above reason etc. as [ be / when equipping a handle with a refilling brush conventionally / no necessity for cautions or practice ] have been made. The Si reason and twisting and wrapping the axial part of a wire refilling brush in a plastic have been performed. Since Acceptance of the axial part wrapped in the plastic and a handle puts in and the fitting accuracy with a socket is determined in the accuracy of the shape of a mold (model), it can raise. That is, a refilling brush fits in in the state of [ always perfect ] K Yo Si as if it attaches to the prescribed position of a handle. However, this formal paste fill brush is not conventionally fixed to a handle. Therefore, a brush cannot be firmly held to the exact holding position (prescribed position). [Means for solving problem] according to the present invention, the whole is in a plastic -- What -- it is smooth, and the sleeve which is not provided with the screw part annexs to a long and slender tooth brush handle, and it may have comes to let six persons and a sleeve slide forward and backward along the end of the handle in it. A penetration hole provides in the tip part of a handle at a transverse direction, Kunihito (major diameter) of specified shape is provided in Osh and its hole, and the plastic collar fabricated in the Twist wire axis part with a plastic enclosure part can be easily stored now in Kunihito. K The shape of the above-mentioned hole and color corresponds mutually, can insert in a book in the state where there is almost (or completely) between [ no ] FJ in a hole, and has become as [ arise / large shakiness / at all ]. If it lets a sleeve slide on color and engaging of clutch is carried out to a wire axis part with a plastic enclosure part, a brush will be held by a zipper-like holding state. As for the outside dimension of a wire axis part with a plastic enclosure part, it is preferred to make it in general the same as the outside dimension of a toothpick. If it is made such, both a brush and a toothpick can be used for one end of the handles, or both ends, attaching it. [Example] Next, a Yo Si example is described to a drawing. The handle (Drawing 1, Drawing 2) of the present invention example is provided with long and slender handle member 10. thick central portion 12, thin both-ends portion 14, and t6 provide and appear in handle member 10. It has turned at each end portion 14.16 to long and slender - and Rundle member 10 at an angle of [ A and B ] about 160~150 degrees. Hole 23 which Purchase in a transverse direction establishes that in each end 20.22 of handle member 10, and it is Appear. The central axis of those holes 23 is located on the plane containing angle ASB. - As for Rundle, making with a moulded plastic is preferred. Kunihito who shows with numerals 24 (Drawing 4) forms in hole 23, lot-of-money Setting of whether Diameter Si of color 32 of plastic enclosure part 26 (Drawing 5) is also very slight is carried out, and it comes out of Lacy and its diameter. Enclosure part 26 is molded into the circumference of Torsion wire 28 of opposite structure. As for wire 28, making from stainless steel is preferred, and it forms the axial part and anchoring fixed end part of brush 30 between teeth. plastic enclosure part 26 (anchor axis part), and it and one be [ like ] alike color 32 at a brush axis part -- Cyanqua 1 member is formed. Although an anchor axis part (26) can be inserted in easily [ hole 23 ] and color 32 fits into Kunihito 24 in that case, since the gap is very small, an anchor axis part (26) and color 32 do not shake to the grade which poses a problem within hole 23. hole 230 size shape is set up suitably, and inserts the end of toothpicks, such as upsilon and wooden, in hole 23 in the state of adhesion, and Yo Si predetermined puts it on friction -- the button has become so that it can hold. Since hole 23 of the both ends of a tooth brush handle has the same size shape, they are a brush and a nail. Which end of a handle can also be equipped with a branch, and both ends can also be equipped. As most clearly shown in Drawing 5, the former and the appearance twist refilling brush 34, and it is wire structure. With of between teeth or a tooth can be made to be able to respond to the brushing conditions of a root, and can change the shape of brush 34 into various shape, such as a cone and a cartridge. Any of the comparatively thin hair which forms the brush of the hardness of a degree in the middle, and the thick hair which forms a hard brush may be provided in brush 34. Those hair may be any of natural material and a synthetic resin material (preferably nylon). Brush either the other above-mentioned brush structure or the same structure can use the Twist wire spring with a plastic enclosure part by the present invention. Moulded plastic enclosure part 26 and power 2-32 are added to common brush 34. It can attach to they being twisted, and being able to attach them by the suitable method for the circumference of wire axis part 28, for example, they putting details 28 into a prescribed position, and performing mold molding. Between color 32 and brush 300, it remains covering length 36 with wire axis part 28. Although Si past To with the long length 36 of the non-supporting portion of wire axis part 28 will arise in Lari and that case in bending etc. if it constitutes so that an exposure state may only twist to the hole of a handle and a user may let wire 28 pass, In an above-mentioned structure, length 36 can be set up short enough to such an extent that such bending etc. can be prevented. Length 36 is long to such an extent that it functions appropriately as a brush. Thus, Yo Si and axial part length can be set to having provided color 32 at a suitable value. two 24 becomes the shape corresponding to mutual with plastic enclosure part 26, color 32, and hole 23 -- Si, and a suitable brush, - and Rundle fitting state are acquired certainly. A size sets up crab 7-32 (expansion 7 lunge) to fit into two persons 24 of hole 23, and the projection length of a brush is uniformly maintained from reed and it K. Push is stabilized by this and shakiness can be prevented. Sleeve 40 (Drawing 4, M2 figure, Drawing 7, Drawing 8), K as shown in Si who size shape set up and advanced 24 in IJ and its state where it covered, to hole 23 and the position which two persons are made to expose completely so that it might hang over small opening portion 14.18 of a handle, and Drawing 7, the brush was retreated to the position fixed to a prescribed position -- it has become as [ A / it ]. The portion of the 1st length nearest to hole 23 is cylindrical, and the internal shape of sleeve 40 is 6 To. As for the above-mentioned internal shape, the portion of the 2nd length is tending to put [ come ] a sleeve on the end of one handle in the shape where Taber was attached slightly, at the time of 6 Si and manufacture. K Bottom 41 of ends 2G and 22 is flat, and has become as [ be / it / easy to capture color 32 (expansion 7 Ebony) of Ah Si and a brush ]. The termination of sleeve 40 serves as reinforcement upheaval part 42, and a woman requires it that it is easy to perform maintenance and movement of a sleeve. Two projections 44.4B which the physical relationship of the side opposite to requires mutually provide at each tip of a handle, and it regulates advance of Lacy and a sleeve. pushing sleeve 40 in the assembly after manufacture -- the Yo Si above-mentioned projection -- Power Si Overcome and .. it is made to move onto y dollars -- the key which is not pulled by the power of Kana after it -- it does not drop out of Si, a sleeve, or - and Rundle. When an inner side taper portion functions as an inside of a proposal at the time of a sleeve sliding on projection 44.46 top and there is no brush in hole 23, the reason is in order to prevent omission of K Yoshi Sleeve as if the other end of A IJ+ The engages with a projection. Infundibular opening 48 and circular opening 50 which follows it provide in the undersurface (113 figures) of a sleeve, and it is Appear. When 5th [ The ] figure paste fill brush is in a prescribed position, it lets a sleeve slide in the direction A of Drawing 7 on it. Infundibular opening 48 shows portion 52 below color 32 to it, and sends it into circular opening 50. Shoulder 54.54 of an opening 500A mouth engages with holding portion 52 under color 32, holds a brush, and fixes maintenance color 32 to 230 dishes of hole hole 24. When removing and exchanging refilling brush 34, first, it lets sleeve 4o slide in the direction B, and two persons release color 32 from 24. Next, a brush is drawn out from a hole. A new brush is inserted, and it lets sleeve 40 slide in the direction A, and holds a brush. The structure of the present invention explained above can be changed in various forms, and the present invention also includes the equivalent structure [ depend ].
