Description

Akira fine manual 肅 brush art

The present invention relates to appropriately replaceable toothbrush carts Li Tsu di brush bristles. BACKGROUND

For example, JP-A-1 0 - The 9 9 1 3 3 JP, discloses capable toothbrush replaced carts Li Tsu di brush bristles. The toothbrush is a flocked stand instead Burashuni' preparative those have configured detachably relative to head portion to the body of the toothbrush, which can be fitted recess (box) the flocking stage the heads portion is made form and with that, the through hole of the order to press-fit the flocked base-side projection is formed on the bottom surface of the recess. For this reason, it is possible to Ri by the and the child to be press-fitting the projection into the through-hole crowded because fitting the flocking stand in the recess of the heads part, and the child to be attached to the head part f the place of Burashuni' door is, or worn decreased brush hair since it is and the child to replace with a new brush hair, without the replacement of the brush body, requires only the replacement of changed Burashiyuni' Tonomi, and the child to achieve a resource saving of low-cost reduction and plastic material it can.

In the above-described toothbrush, for recess and the through hole of the head portion can be restricted Re debt flocked base to, although at the time of attachment of the place Burashuni' bets can and this to prevent rattling, retaining mechanism but because it does not exist, the oar Miya elastic deformation of the fart head portion such as during tooth brushing, liable lifting or loosening from place Burashuni' Bok of heads portion gradually was poor in fixing reliability. In addition, Wae' water but Ri balls some of the water to enter likely to occur in the recess of the de part, at the time of exchange of the brush hair dirty Standing eye to Roken was in recess at the time of use, leading to some of the unsanitary feeling.

And as to solve this problem, the present inventor has disclosed a 2 0 0 1 one 1 0 5 1 8 No. 9 No. earlier. Its toothbrush, the heads 2 2 integrally and continuously from the handle portion 2 1 of the hub brush body 2 0 made of resin shown in the first FIG. 1, instead Burashuni' bets 3 0 shown in the first 2 figure detachable possible to be a replacement brush hair type tooth brush became. Head portion 2 2 of the toothbrush body 2 0 is a unit receiving plate portion 2 (3) formed in cross section crowned consisting longitudinally and Wataru connexion flat surface 2 3 a and the inclined surfaces 2 3 b, 2 3 c a. The unit receiving plate 2 3 is provided at two locations at an interval on a flat surface 2 3 a positioning through-holes 2 3 d, 2 3 e and, during the positioning through-holes 2 3 d, 2 3 e in through the Yuni' preparative receiving plate portions 2 3 in the thickness direction of that, engaging claw portion F from the hole wall in the hole, but the engaging hole 2 3 f made out tension integrally, instead Burashuni' DOO 3 0 curved guide wall 2 which engages in the flocking stage 3 1 of one end curved edge 3 1 a 3 g and, above wide-like female communicating with the handle portion 2 1 side from the curved guide walls 2 3 g and a part 2 3 h. Hanging stop hole 2 3 f is a long hole of Yuni' preparative receiving plate 2 3 longitudinal formation along the vinegar Li Tsu preparative shape, a line connecting the hole centers of the positioning holes 2 3 d, 2 3 e It is slightly displaced in forming the (center line). Their to, on the back side of the engaging hole 2 3 f gentle slope S which contact the engaging claw portion F is formed. Handle part 2 1 of the hub brush body 2 0, and the resin core member 2 1 a, and a rubber layer 2 1 b, which is overmolded thereon, the resin core member 2 1 a is , and the mold positioning hole H penetrating the end portion, and a plurality of communication holes penetrating at intervals in the longitudinal direction (not shown), is in a plurality of communication holes is embedded rubber ing.

On the other hand, Burashiyuni' preparative 3 0 instead consists flocking stage 3 1 and brush bristles 3 2 which was planted in this flocking stage 3 1 protrudes from the back surface downwardly spaced longitudinally unit receiving plate and part 2 positioning through-holes 2 3 3 d, 2 3 揷 fittable to e were included projections 3 1 b, 3 1 c, from the back between the projections 3 1 b, 3 1 c insert downward and the object to be hung Tometsumehen 3 1 d fittable to Yuni' preparative receiving plate 2 3 engaging hole 2 3 f protrude, above the wide-like male part 3 which projects longitudinally from one end curved edge 3 1 a and a 1 e. The latched pawl 3 1 d is a wide pawl piece formed along the longitudinal direction of the bristle base 3 1, inserted narrowing collision electromotive unit 3 1 b, 3 1 c of the protrusion center connecting line (center line) It is slightly displaced by forming a L 2.

When mounting the Burashuni' preparative 3 0 instead Yuni' preparative receiving plate 2 3, as the first 3 view (a) shown in the first FIG. 3 (b), Yuni' preparative receiving plate portion 2 3 positioning holes 2 3 d, 2 3 e and interlocking hole 2 3 f and exchange Brassus Stevenage preparative 3 projections 3 1 insert the 0 b, 3 1 c and the HiKake Tometsumehen 3 1 d Komu was inserted the first 3 Figure as (c), the engaging hole 2 3 for HiKake Tometsumehen 3 1 d claw portion F 2 of is stopped consuming the engaging claw portion in f, positioning through-holes 2 3 d, 2 3 projections 3 1 b insert and e, can 3 1 is possible to get a 耐Ka stronger than solid Do fastness dislodgement and c is. Conversely, when removing the Burashuni' preparative 3 0 place from unit receiving plate 2 3 claws F 2 of Yuni' preparative receiving plate 2 3 the latched pawls exposed on the rear surface of 3 I d with fingertip Ri by the and this bending press in the jar by rubbing in the direction of the arrow in the first FIG. 3 (c), because the consuming stop is disengaged, the first 3 Burashiyuni' door 3 0 from the first FIG. 3 (b) instead of Fig. can and child pull out as are shown in (a). When moving rubbing the claw portion F 2 in this fingertip, since the gentle slope S is formed, it can be secured Ri those of the claw portion F 2 of the fingertip, as easily rubbed Ri, implemented to facilitate the latching stop release operation it can. Further, since the heads 2 on the 2-side water reservoir or Ri does not occur, there is no unsanitary feeling.

However, even the above-mentioned toothbrush, there has been a problem Do you Yo follows. (1) replacement Burashuni' preparative 3 0 when replacing the like in the case for releasing the hooking state between the engaging hole 2 3 f and the Kaketometsumehen 3 1 d is an operation that the toothbrush body 2 0 hold , there is almost necessary perform at the same time and the operation of moving rubbing the claw portion F 2, and an operation to pick out the Burashuni' door 3 0 place at your fingertips in the fingertip. In such an operation, because of the one hand you are holding the toothbrush body 2 0 pick out the Burashuni' door 3 0 place along with the move rubbing the claw portion F 2 in the reverse of the hand, it is impossible considerable, toothbrush main body 2 0 move rubbing the claw portion F 2 at the fingertip of one hand that is gripping, good to throw out the Burashuni' door 3 0 place in the opposite hand. And rollers, engaging hole 2 3 f is 揷 was included projections 3 lb, 3 1 c Ri Contact is formed between and the latched pawl 3 I d is the protrusion 3 lb Insert, 3 1 because it is formed between the c, fingertips claw portion F 2 of one hand gripping the toothbrush body 2 0 is hard to reach, there is no margin enough to move rubbing it, it is difficult unlatching operation there is a problem in that.

(2) Further, the direction of moving rubbing the claw portion F 2 at fingertip, Remind as arrows in the first 3 view (c), is in a direction perpendicular to the longitudinal direction of the toothbrush body (center line direction) Therefore, strong and unreasonable to fingering, and even more by the left and right differences and handedness differences of the hand lifting bunch of the toothbrush body, there is also the locking release operation is rather confusing, there is a problem that it is difficult to release.

In view of the above problems, an object of the present invention, while maintaining the fixing reliability instead Burashiyuni' bets, Ri FOR A FULL improve its retaining mechanism, thereby improving the operability of the locking release It is in the child provide a toothbrush. Disclosure of the Invention

The present invention provides a detachable toothbrush Burashuni Tsu bets instead head portion from the handle portion of the toothbrush body to the front side, in the head portion to that, Yuni' preparative receiving plate for supporting the bra Shuni' bets instead and one location of position-decided Me holes also less provided parts, front to back through in the Hare Chi shank side of the unit receiving plate portion, the hooking claw portion from the hole wall in the hole exit tension integrally comprising hanging has a locking hole, is set to or replaced Burashiyuni' DOO, and brush bristles planted in flocking stand, protrudes from the back surface of the bristle base, can be fitted into the positioning holes of 揷 was included protrusion When, made and a the latched claw possible stop consuming the engaging hole to protrude from the back surface of the planted hairs stand.

In addition to the above configuration, provided with a separate engaging holes near the tip end of the unit receiving plate may be provided with a separate the latched pawl piece flocking stand tip-sided. The Burashuni' door of the distal end side of the float instead can be prevented.

When attaching the Burashuni' bets instead Yuni' preparative receiving plate portion is to 揷 the 揷 and Write-projecting portion and the locking pawl of Burashiyuni' bets instead positioning through hole and the engaging hole of Yuni' preparative receiving plate portion writing the, since the claw portion of the engaging claw piece is stopped consuming the engaging claw portion in the engaging hole, robust latching fixing force loss than 耐Ka of the positioning holes and 揷 was included protrusion it is possible to get a. Conversely, when removing the Burashiyuni' bets changed from Yuni' preparative receiving plate portion is moved Ri rubbing the claw portion of the engaging claw exposed at the back surface side of the engaging hole while gripping the heads portion with one hand with a fingertip at the same time, Ri by the and the child out only picked the Burashuni' door instead of in the opposite hand, the consuming because the stop is out, replaced Burashuni' bet a can and Yuni' door receiving plate portion or we simply pull out this. Ni will this Yo, for engaging hole is formed in a jar Chi shank side of the unit receiving plate portion, the fingertips of one hand gripping the toothbrush body is it easy to reach the claw portion of the latching pawl Ri, latching release operation is very easy.

Here, the hooking claw portion is made out tension to the through-hole side determined position from the handle portion at a substantially center line of Yuni' preparative receiving plate portion, 揷 substantially centerline claw portion of the flocked base of the locking pawl made out tension from and inclusive protrusion side to bristle base of the longitudinal one end side. Since fingertip can unlatching By moving rubbing the other longitudinal end side touch the rear surface of Yuni' preparative receiving plate portion, ambiguity of latching release operation by the left and right difference and dominant difference of the hand gripping the toothbrush body Oko Razz, also a quick release operation can be realized. Furthermore, since that can be inserted or removed slider die from the longitudinal one end side between the claw portion of the place Burashuni' Bok flocked block and HiKaketome claw piece at the time of molding the enables 榭脂 molding of multi-cavity, low cost of the replaced Burashuni' door can also be realized.

Conversely, the latching claw unit is made out of tension from the positioning through-hole side in the substantial center line of Yuni' preparative receiving plate portion to the handle portion, flocked with claw portion substantially at the center line of the bristle base is of the latched pawl even if made out tension to stand in the longitudinal direction one end side from the inserted narrowing projections side, the substantially same effect can be obtained.

Here, the this also shallow wide recess Ri by the engaging hole is formed desired on the back side of the engaging hole arbitrariness. Since the fingertips at the time of the release operation falls naturally into the recess in the finger to explore, the release Position emissions can and tactile instructed child. Further, since the claw portion of the locking pawl by the 瘙 Mino exists does not protrude from the rear surface of the unit accepted the plate portion, thereby preventing the unintended generation of locking release.

Incidentally, the positioning through-hole is a tapered hole, arbitrary desired and inserted narrowing tapered projecting projections and the formation child to have. The frictional resistance is reduced, it can be realized smoothly fitting and removing the Positioning through-hole and 揷 was included projections. Made integrally includes the longitudinal end portion of the edge guide upright wall portion engageable flocking stand between the head portion and the handle portion to. When Komu to 揷 the Burashuni' preparative protruding portion and the locking pawl Insert the place of the positioning holes and the engaging holes of Yuni' preparative receiving plate portion, the Burashuni' guide upright wall portion the edges of one longitudinal end portion of the Bok place simply pushing operation by letting you engage, because Burashuni' projections insert bets and the latched pawl place is fitted into the positioning through-Ana及 beauty engaging hole of Yuni' preparative receiving plate portion, attaching operability it is and this enhanced. Moreover, Nari is section modulus rather large by the guiding force standing walls, it is a this to increase the flexural rigidity. The flocking stage has a male portion which projects through the connecting portion in the longitudinal direction from the edges of one longitudinal end portion, Head section, Ri Contact is formed through a groove which divides the guide upright wall portion, arbitrary desired and this has a male portion matable female portion. Between the heads portion and the handle portion rather large, the amount seen oar during toothbrushing, but hooking state between the engaging hole and the engaging claw of the proximity deviates possibility also, male part fitting into the female portion as you case, both exert anchoring effect, because the tensile force to the consolidated portion that fits in the groove when the bending deformation is applied, the fool Ri force Kaketomeka that can be reduced the amount of deflection as the reaction surely it can be sustained.

Note that arbitrary and the male portion and the connecting portion and the tapered projections, are to form the female part and the grooves in the tapered one hole desired. Smooth mating of the male and female portions. Away leaving can be realized. The initial tensile stress can incrementally applied to the constricted shaped connecting portion in the fitting process with the male and female portions, the tensile stress at the time the pawl portion of the locking piece is fastened consuming the hanging claw portion Ri Do to the conversion child to sustainable force hooking direction, consuming stop is reliabilized. Further, autonomously restore from trigger operated alone, Risono claw portion by the still remaining tensile stress hooking claw portion for releasing the hooking state lend rubbed moving the claw portion with the fingertip of the hooking piece since on the child withdrawal, there is no need to push the claw portion of the hooking piece from the back, the latching release is very easy.

Furthermore, arbitrary desired that the surface of the Yuni' preparative receiving plate portion is an inclined surface substantially chevron. It may be a gentle slope. When the surface is a flat surface, easily Ri ball with a gap foreign matter enters between the brush base, but unsanitary, if the inclined surface, though the foreign matter is likely to enter the gap formed rather, since the removable with cleaning, it is possible to hygienic use.

The present invention is also applicable to an electric toothbrush having a head portion and a handle portion slightly larger diameter with a built-in motor or the like to this to a Removable ability. To Tsu If detachable exchange Burashuni' door instead of the Interview two Tsu door plate receiving plate portion of de section, head section is also unnecessary in the exchange to.

BEST MODE FOR CARRYING OUT THE INVENTION

It will now be described with reference to embodiments of the present invention in the accompanying drawings.

Toothbrush of the present example, instead of detachable Burashuni' preparative 3 0 instead of carts Li Tsu di expression head unit 2 2 to made integrally and continuously from the handle portion 2 1 of the toothbrush body 2 0 made of resin a brush hair type 齒 brush.

Head portion 2 2 of the toothbrush body 2 0 has a Yuni' preparative receiving plate portions 2 3 sectional chevron shape as denoted in FIG. 2 (c). The Yuni' DOO receiving plate portion 2 3, a positioning through-hole 2 3 d, 2 3 e provided at two locations at an interval on the center line, front to back through in the handle portion 2 1 closer, the hole wall in the hole and a pawl portion F t gar body specifically to tension out to become hooking hole X. On the back side of the engaging hole X the engaging hole X Ri it also shallow and wide recess W is formed. The recess W has a bottom surface on both sides and the handle portion side of the engaging hole X. Latch claws F i is out stretched wider shape from the handle portion 2 1 side on the center line of Yuni' preparative receiving plate 2 3 to the positioning through-holes 2 3 d side. Positioning holes 2 3 d, 2 3 e is Ru loose Te one path one hole der.

On the other hand, Burashuni' preparative 3 0 instead consists flocking stage 3 1 and brush bristles 3 2 which was planted in this flocking stage 3 1 protrudes from the back surface downwardly spaced longitudinally unit receiving plate part 2 3 positioning holes 2 3 d, 2 3 and 揷 was included projections 3 I d, 3 1 c can be pressed into e, flocked in even one longitudinal end closer Ri by 揷 was included projections 3 1 c and a target multiplied Tometsumehen Y capable stop consuming the hooking hole X protruding from the rear surface of the base 3 1. Claw portion F 2 of the hooking claw Y consists out tension wider shape to planting base of the longitudinal one end side from the bristle base 3 1 projections Insert center line portion 3 1 c side. The width of the claw portion F 2 is narrower Ri by the width of the latch claws, without forming the Ri or water reservoir on top of the latch claws F t, and summer Ni Let 's you exert a drainage effect.揷 was included projections 3 1 d, 3 1 c is a loose tapered protrusion.

The flocking stage 3 first longitudinal end portion 3 1 a of the edges engageable curved guide upright wall 2 3 g is provided between the head portion 2 2 and the handle part 2 1 a toothbrush body 2 0 to the It has one body to. The flocking stage 3 1 has a longitudinal end portion 3 1 previously wide made to protrude through the constricted shaped connecting portion 3 1 e in the longitudinal direction from 緣 of a like male portion 3 1 f, to the head portion 2 2 is formed on the handle part 2 1 side through the narrow 窄状 groove 2 3 h to divide the curved guide upright wall 2 3 g, possible fitting engagement with the above wide-like male portion 3 1 f Sakihiro and a Jomesu unit 2 3 i. Earlier wide-like male portion 3 1 f is a loose tape Per-like projections, previously wide-shaped female part 2 3 i is a loose tapered bore.

If attaching the Burashuni' preparative 3 0 instead Yuni' preparative receiving plate 2 3, immediately Chi, Burashuni' preparative 3 instead unit receiving plate 2 3 positioning holes 2 3 d, 2 3 e and the engagement hole X projections 3 1 insert the 0 d, 3 when plugging the 1 c and HiKake Tometsumehen Y, first, instead Burashiyuni' bets 3 0 of the longitudinal end portion 3 1 a of the edge of the curved guide upright wall 2 3 When write-operated press in the earthenware pots by engaging the g, as shown in FIG. 5 (a), above the wide-like male portion 3 1 f and constrictions shaped connecting portion 3 1 e is previously wide-shaped female part 2 together fitting into 3 i and stenosis shaped groove 2 3 h, 揷 and included projections 3 I d, 3 1 c and HiKake Tometsumehen Y is Yuni' preparative receiving plate portion 2 3 positioning holes 2 3 d, 2 3 enters the e and engagement hole X, as shown in FIG. 5 (b), the tip end of the claw portion F 2 of the hooking pawl which Y is flexion along the inclined surface on the engaging claw portion F t after descent, shown in FIG. 5 (c) As, since the back surface of the engaging claw portion in the engaging hole X is HiKake Tometsumehen Y claw portion F 2 of the stop consuming, positioning through-holes 2 3 d, 2 3 e and揷was included projections 3 I d, 3 1 to obtain a strong locking fixing force over disconnect Ke耐Ka the c Ru can and this. Conversely, when removing the Burashuni' preparative 3 0 place from unit accepted the plate section 2 3, the back side of the engaging hole X while holding the Yuni' preparative receiving plate 2 2 side of the handle part 2 1 in one hand the claw portion F 2 of the hooking claw piece Y which issued dew at the same time and move rubbed with a thumb or index finger, picked the Burashiyuni' door 3 0 place in the reverse hand Ri by the and this heading, for the consuming stop is out , instead Burashuni' door 3 0 Ru can and child pull out Yuni' door receiving plate section 2 3 or et al. Ni will this Yo, since the engaging hole X is formed in the Hare Chi handle part 2 1 side of the unit receiving plate 2 3, the fingertip of one hand gripping the toothbrush body 2 0 until the claw portion F 2 becomes easy reach, the locking release operation is very easy.

Further, latch claws F i is out tension from the handle portion 2 1 side on the center line of Yuni' preparative receiving plate 2 3 to the positioning through-holes 2 3 d side, the claw portion F 2 of the hooking pawl Y have come up tension from the bristle base 3 1 揷 was included projections 3 1 c side center line of the bristle base of the longitudinal one end side. Therefore, in the locking releasing operation by touching a finger to the back surface of the Interview Knitting preparative receiving plate 2 3 is Ino yo By moving rubbing the other longitudinal end portion side, the differences Ya left and right hand gripping the toothbrush body 2 0 Razz Oko is ambiguity of the locking release operation by the dominant hand difference, also Ru can achieve rapid release operation.

Further, since the engaging hole X and I also shallow wide recess W Ri is formed on the back surface side of the engaging hole X, fingertips when clearing operation drops naturally to the depression W in the finger explores because, Ru can and tactile instructed child a release Position down. Moreover, since the claw portion F 2 of the hanging Tometsumehen Y by the presence of the recess W does not project from the rear surface of the Interview two Tsu preparative receiving plate 2 3, it can be prevented unintended occurrence of locking release.

Its to the positioning through-holes 2 3 d, 2 3 e is a tapered hole, inserted narrowing projections 3 1 d, 3 1 Since c is a tapered protrusion, the positioning through-holes 2 3 d, 2 3 e smooth fitting and extraction of the 揷 and inclusive protrusion portion 3 I d, 3 1 c can be realized.

On the other hand, integrally have a flocked base 3 1 of the longitudinal end portion 3 1 a of the edges engageable curved guide upright wall 2 3 g between the heads 2 2 and the handle part 2 1 and composed. Units receiving plate portion 2 3 positioning holes 2 3 d, 2 3 e 及PiKaketome 揷 of Burashuni' DOO 3 0 instead hole X and included projections 3 1 d, 3 1 c and the Kaketometsumehen Y the time Komu to 揷, only operations pushing in the earthenware pots by the Burashuni' preparative 3 0 one longitudinal end portion 3 1 a of the edge of the place to engage the curved guide upright wall 2 3 g, instead Burashuni' Bok 3 since cuttings narrowing projections of 0 3 1 d, 3 1 c and HiKake Tometsumehen Y fits into Yuni' preparative receiving plate 2 3 positioning holes 2 3 d, 2 3 e and engaging hole X, attached can and child to improve the operability. Also, because between has become like constriction of the head portion 2 3 and the handle part 2 1 to, Ri by the integral formation of the curved-shaped guide standing wall section 2 3 g, the cross-sectional coefficient rather than size now, it is and this increase the bending rigidity. Claw portion F 2 of the hooking claw Y is generally formed between the forming department line both ends of the curved guide upright wall 2 3 g and curved proposed in upright wall 2 3 g curved central and which, influenced by the bending deformation of Yuni' preparative receiving plate 2 3 is summer less susceptible.

Usually, Tsu between de 2 2 and the handle part 2 1 rather large, the amount seen scull when-out 齒磨 also Re 虡 the latching state is out of the engaging hole X and the latched claw Y proximity to some though, the previously wide-shaped female part 2 3 i and stenosis shaped groove 2 3 h to Sakihiro like male portion 3 1 f 及 Pi constricted shaped connecting portion 3 1 e is fitted, both exert anchoring effect and, since the tensile constricted shaped connecting portion 3 1 e fitted in the constricted groove portion 2 3 h force during bending deformation is applied, and only the force interlocking hole X can be reduced deflection amount as the reaction HiKaketome the latching mosquito the claw piece Y can stably maintain.

Earlier wide-like male portion 3 1 f and the connecting portion 3 1 e is a Te one path one shaped protrusion, since Sakihiro Jomesu unit 2 3 i and the groove 2 3 h are tapered holes, rather low frictional resistance now, Ru can be realized smoothly fit-away removal of the previous wide-like male part 3 1 f and Sakihiro Jomesu section 2 3 i. The above wide-like male portion 3 1 gradually be granted to增的the initial tensile stress in the constricted portion in f and Sakihiro Jomesu unit 2 3 i and the fitting agreement process, the tensile stress claw portion F 2 is hooking becomes a child converted to sustained forces latching direction when the locking latching the pawl portion F i, consuming stop is reliabilized. In addition, the claw portion alone trigger operation for releasing the hooking state of the hooking claw portion of the F 2 by moving rubbed with a finger destination, still remain due to the tensile stress Ritsumebu F 2 is the engaging claw portions F i since on the child autonomously return disengaged from, with little need extrusion force from the back of the claw portion F 2, latching release is facilitated.

Since the surface of the unit receiving plate 2 3 is an inclined surface substantially chevron, although foreign objects into the gap G between the inclined surface and the stems 3 1 of that is likely to enter, and can be removed by washing Therefore, it is possible to hygienic use. Further, by using the gap, it is easy removal operations instead Burashiyuni' bets are. Industrial Applicability

The cormorants I described above, the present invention includes the following effect.

Is a (1) Head portion, and front and rear through in units receiving plate portion sac Chi handle portion closer, the hooking claw portion from the hole wall in the hole and a hooking hole made out tension integrally Yes and is, also as a place Burashiyuni' bets, since made and a the latched claw possible stop consuming the engaging hole, while maintaining the fixing reliability Burashuni' bets instead, hanging since the stop hole is formed in a jar Chi shank side of the Yuni' door receiving plate portion, the fingertips of one hand gripping the toothbrush body Ri an easy reach to the claw portion, the locking release operation is very easy.

(2) engaging claw portion is made out tension from the handle portion on the center line of the unit receiving plate portion to the Positioning through-hole side, the pawl portion of the locking pawl pieces Insert in flocking stand center line since made out tension from the projecting portion side to the bristle base of the longitudinal one end side, since it by moving rubbing the other longitudinal end portion side touching the fingertips on the back of the unit receiving plate portion in the latching release operation, Razz ambiguity of latching release operation by the left and right difference and dominant difference of the hand gripping the toothbrush body Oko, also possible to realize a quick release operation.

(3) for engaging hole back side of recess wider the shallower Ri by an object to be hooked holes in the are made form, falls off naturally to fingertip the recess in the finger explores the time of release operation since, the release Position emissions can and tactile instructed child. Further, the claw portion of the locking pawl by the presence of this depression is because it does not protrude from the rear surface of the unit receiving plate portion can be prevented unintended occurrence of locking release.

(4) a positioning through hole and a tapered hole, a projection Insert taper - because it is formed as a shaped projections, the friction resistance is reduced, smooth fitting between the positioning holes and 揷 was included protrusion the engagement or disengagement can be achieved.

(5) Since composed integrally includes the longitudinal end portions of the edge engageable guide upright wall portion of the bristles stand between the heads portion and the handle portion, positioning through the Yuni' preparative receiving plate portion when Komu to 揷 protrusions insert of Burashiyuni' bets instead hole and engaging holes and the engaging pawl, push in the earthenware pots by engaging the guide upright wall portion the edges of one longitudinal end portion of the place Burashuni' bets simply by operating, since 揷 was included protruding portion and the locking pawl of the place bra Shuni' bets fits into positioning holes 及 Pi engaging hole of Yuni' preparative receiving plate portion, and the arc enhanced attachment operability it can. Further, since the between the head portion and the handle portion has a normal constricted shape to, Ri by the integral formation of the guide upright wall portion, Nari is section modulus rather large, and a benzalkonium enhance flexural rigidity it can.

(6) planted stand has a male portion which projects through the connecting portion in the longitudinal direction from the edges of one longitudinal end portion, the head portion is formed through a groove which divides the guide upright wall portion , because it has a male portion and fittable female part, the Tsu between de portion and the handle portion is rather large, the amount seen oar during toothbrushing, the proximity of the engaging hole and the pawl piece although hooking state deviates possibility also, when the male portion is fitted into the female part, both exert anchoring effect, because the time of bending deformation acts pull tension to the connecting part which fits into the groove , Rubakari force possible to reduce the amount seen oar as a reaction can stably maintain the hooking mosquito between the engaging hole and the engaging claw piece.

(7) the male portion and the connecting portion and the tapered projection, which is formed by the female part and the grooves between tape par holes, frictional resistance is reduced, - smooth fitting of the male and female portions Ru can be realized withdrawal. The initial tensile stress to the connecting portion can incrementally imparting the fitting process with the male and female portions, sustained hooking direction at the time this tensile stress is that the claw portion is stopped consuming to the holding pawls a force to be on the child conversion, consuming stop to ensure reduction. In addition, even in the only opportunity operation for releasing the hooking state to move rubbing the claw portion with a fingertip, Ritsume part by the still remain tensile stress becomes a child autonomously return withdrawal from the latched pawl because, without the almost need a push out Shi force from the back of the claw portion, the locking release is facilitated.

(8) In addition, arbitrary desired that the surface of the unit receiving plate portion is an inclined surface substantially chevron. Of the inclined surface and the gap between the stems that foreign matter is likely to enter, it becomes possible to remove in the cleaning, it is possible to hygienic use.
