The content of the invention

Problems to be solved by the invention

Hereinafter, illustrate from the 1st bending section<4a>(the 1st clamping part) and the 2nd bending section<4b>The side of (the 2nd clamping part) (right side and left side in Figure 13), is grabbed with thumb and forefinger and pinches resin-made elastomer<9>In the case of caused state (reference picture 13)。

《Buckle<A>》

With thumb and forefinger to pin<7>It is inserted in pin insertion hole<10>The resin-made elastomer of interior pin insert state<9>Carry out Grab and pinch and from the pin<7>Extract resin-made elastomer<9>, self-marketing carry out extraction operation when the resin-made elastomer<9> Grab that to pinch form as described below.

Buckle<A>Be 5.4mm × 4.0mm in the case of small buckle, in the case of big buckle it is smaller for 6.7mm × 5.0mm, resin-made elastomer is pinched so grabbing<9>Finger two finger tips to exceed downside curved protrusion downwards<e>'s Grab to lower side and pinch resin-made elastomer<9>State be that downside convex portion hooks and refers to grab and pinch form.Hook to refer to as the downside convex portion and grab The reasons why pinching form is because of curved protrusion on the downside of (1)<e>Lower angle (lower rims) in the case of small buckle radius (R) For 1.0mm, radius (R) is 0.9mm in the case of big buckle, is the curved lower angle significantly bent, curved protrusion on the upside of (2) <d>With downside curved protrusion<e>For identical fineness degree, (3) annular recessed portion<11>Narrower width up and down, be 1.1mm~ 1.3mm, (4) annular recessed portion<11>With upside curved protrusion<d>And with downside curved protrusion<e>Connection be smooth bending Form is connected, (5) from the point of view of the finger pinched grab, upper and lower distance is the resin-made elastomer of 4mm~5mm smaller form<9 >The finger pinched relative to grab is actually the flat construction body of curved lower corner shape.

In the less buckle for the 4mm~5mm for grabbing the flat construction body for pinching curved lower corner shape<A>In the case of, In order that resin-made elastomer<9>Do not depart from finger, also have to sometimes into be about to finger be strongly hooked on than maximum hook The position in finger portion is downside curved protrusion<e>Maximum protruding parts on the lower such in inclined plane inwardly grab pinching work. So from buckle<A>Extract pin when, make finger tip strongly hooking in downside curved protrusion<e>Bottom rake inwardly Buckle is kept in the state of point<A>, so as to make the operation of extraction perforation ear pendant pin easily carry out.

Upside curved protrusion<d>It in the lower radius (R) of small buckle is 0.9mm to be, radius (R) is in the case of big buckle 1.0mm wall thickness and the bent projection form slowly that obtuse angle is not present.This wall thickness and the bent projection shape bent slowly State, though enhancing grabbing for finger pinch power, damage by pressure deformation it is also smaller, and upward the deformation as buckling deformation in addition by delaying Sliding also hardly occurs caused by slow bending.Therefore, finger will not also deform upward, therefore comfort is poor, finger Positioned at downside curved protrusion<e>And spring member<1>The position of (pin clamping duromer), is strongly grabbed to the position Pinch.

Thus, when enhancing grab the finger pinched grab pinch power when, upside softness tectonic position (upside curved protrusion<d>) Only little by little damage deformation, the hard tectonic position (annular recessed portion in downside by pressure<11>With downside curved protrusion<e>) carry out than upper lateral bending Bent convex portion<d>The small deformation of deformation or hardly deform.If enhancing, which is grabbed, in this case pinches power, can turn into buckle certainly <A>The action (action for departing from finger) extruded from finger.

In order that this is by buckle<A>The action extruded stops, and becomes strongly to be grabbed and pinches the hard tectonic position in downside (particularly downside curved protrusion<e>) side, the meat of finger is gone into the downside curved protrusion<e>Lower side grab pinching work. Also, it ought strongly grab and pinch the hard tectonic position in downside (particularly downside curved protrusion<e>) side when, become carry out to positioned at this The spring member of the inner side of the hard tectonic position in downside<1>From both sides side pushing force enhancing, upside curved protrusion<d> With downside curved protrusion<e>Pin retaining part<4c>Pin chucking power be remarkably reinforced, self-marketing carry out extraction operation resistance it is bright The pin chucking power enhancing action of aobvious increase.

Buckle<A>Smaller be 4mm~5mm, pinches buckle grabbing and extracts the operation of pin, annular recessed portion<11>With it is upper and lower Narrow width and the angle of bend radius (R) in the case of small buckle are 0.9mm, and radius (R) is 1.0mm in the case of big buckle This be not present obtuse angle upside curved protrusion<d>Gently bending connection, so lateral bend convex portion upwards<d>Finger Hooking is weaker.Therefore, upside curved protrusion<d>(remove nail hang part as the finger hooking position of meat hooking for finger Position beyond) function it is weaker.

In addition, not by finger hooking in downside curved protrusion<e>Bottom surfaces and in the case of grab and pinching, or only By finger hooking in upside curved protrusion<d>, annular recessed portion<11>And downside curved protrusion<e>Sidepiece face and grab pinching In the case of, when enhancing carries out grabbing the power pinched, buckle<A>Easily slide and depart from finger and drop.

In addition, buckle<A>It is to make the spring member as hardened member<1>Positioned at resin-made elastomer<9>Main part Form, also, spring member<1>Uppermost position be formed as, in the case of small buckle be located at than annular recessed portion<11> Uppermost position more on the lower and distance 0.25mm position, in the case of big buckle be located at than annular recessed portion<11>Most Upper position more on the lower and distance 0.27mm (elastic structure main part) position extremely narrow configuration.Therefore, ring-type is recessed Portion<11>(elastic structure main part) is integrally formed as by spring member<1>The hard construction formed, and spring member< 1>The downside curved protrusion at place<e>It is again formed as hard tectonic position.

That is, the spring member of hard<1>The annular recessed portion at place<11>And downside curved protrusion<e>It is hard to form downside Tectonic position, spring member is not configured<1>Upside curved protrusion<d>Position forms the soft tectonic position in upside, also, conduct The spring member at the position connected with the hard tectonic position in downside of upside softness tectonic position<1>Uppermost position, with ring Shape recess<11>Uppermost position (=upside curved protrusion<d>Its lowermost position) buckle separate section be in small buckle In the case of be 0.25mm, in the case of big buckle be 0.27mm this narrower buckle distance of separation.

Therefore, buckle<A>Narrower buckle separate section and hardly stretched because grabbing and pinching power, and be not susceptible to Lateral bend convex portion<d>Top deformation deformation, so as in the grabbing and pinch power enhancing operation of finger, become to carry out the hard structure in downside Make position and also strongly grabbed and pinched, sell retaining part<4c>Pin chucking power be remarkably reinforced the enhancing of pin chucking power action.

In addition, on buckle, have in [0018] section of patent document 1 as described below, i.e. " receiving pin<7>When, Can be with finger tip, nail front portion to forming the annular recessed portion in the periphery of buckle<11>Grab pinching ".Even if but actually not by hand Refer to hooking in downside curved protrusion<e>Bottom surfaces, and be intended to make finger tip (meat of finger tip) be located at annular recessed portion<11>To enter Row, which is grabbed, to be pinched, and is dropped due to that can slide disengaging finger immediately when enhancing is grabbed and pinches power, so being pinched in grabbing for being carried out with the meat of finger In, it is not easy to carry out the operation for extracting pin.

In contrast, thumbnail and forefinger nail are being put in into annular recessed portion<11>And grab when pinching, can be more firm Admittedly grab and pinch buckle, can easily carry out extraction operation.Therefore, buckle<A>、Annular recessed portion<11>It is used as " nail Hang part " or " nail grabs the portion of pinching " play function, and play function in " finger grabs the portion of pinching " of the meat of finger not as hooking, this It is fairly good.

The people of nail length and the longer not easy-to-use finger tip of people of manicure on nail, nail grab pinching, so being usually The thumb that will not be contacted each other using nail and the finger belly position of forefinger, which carry out grabbing the finger finger belly position pinched each other grabbing, pinches form ((b) of reference picture 5), carry out the charge and discharge operations of self-marketing.Grabbed at the finger finger belly position under pinching form, as described above, when enhancing Grab when pinching power, buckle<A>、It is extruded from finger and departs from and drop.

《On buckle》

In the buckle of patent document 1In the case of, positioned at the 1st bending section<4a>And the 2nd bending section<4b>Above-below direction Approximate centre position retaining part<4c>, it is located at and annular recessed portion<11>Center<C>Roughly the same position.Separately Outside, as the 1st bending section<4a>And the 2nd bending section<4b>Topmost spring member<1>Topmost, positioned at than ring-type Recessed center<C>Position by the top.

In addition, resin-made elastomer<9>Interior spring member<1>Topmost be located at than annular recessed portion<11>Topmost The position of position by the top.The position for being 0.43mm in the case of big buckle, the position for being 0.37mm in the case of small buckle Put.Therefore, spring member<1>The annular recessed portion at place<11>Nearby because of the spring member of the hard<1>And be formed as not variable The construction of the central hard of shape.In such spring member<1>In the form at center, buckle is pinched by grabbingWhen grab Pinch and strongly act on the spring member to the pushing force of inner side caused by power<1>.Thus, become and in above-mentioned buckle<A> The pin chucking power enhancing that the situation of middle explanation is same acts.

1st clamping part 6a and the 2nd clamping part 6b be inner side also around including fill and be in close contact flexible knot The unitary structure of structure body 2.Thus, the pin 3 of insertion the 1st clamping part 6a and the 2nd clamping part 6b is pushed open towards lateral outer side and Insertion is therebetween.When carrying out the insertion of the pin 3, as the 1st clamping part 6a of hard component and the 2nd clamping part 6b not Shifting ground, while elastic structure 2 is pushed open and deforms elastic structure 2, moved while being opened towards lateral outer side.Elasticity Structure 2 is in its elastic recoil power and wants the 1st clamping part 6a and the 2nd clamping part the 6b elasticity pushed back are pushed back into power to play all the time The state of effect, power enhancing the 1st clamping part 6a and the 2nd clamping part 6b clamping clamped to pin 3 is pushed back using the elasticity Power.

In the present embodiment, elastic structure 2 is cylindrical conformation, so the width at 2 each position of elastic structure is diameter, As specific embodiment, following such size and dimension can be formed as.

The size of elastic structure 2 is as described below：

Upper and lower width is 5.0mm, width 5.5mm.

The width up and down of convex portion 9 is 1.8mm (1.55+0.25), width 5.5mm on the downside of elastic structure, upper edge angle 16 Bend the obtuse angle that cutting angle R is 0.25mm.

The width up and down of top interconnecting part 7 is 0.55mm.

The width up and down of bottom interconnecting part 16 is 0.5mm.

The width up and down of convex portion 10 is 0.975mm, width 5.0mm on the upside of elastic structure.

The width up and down of elastic structure main part 8 is 2.55mm, main diameter 4.5mm.(elastic structure main part with The form that there is a situation where to tilt interconnecting part (comprising bending) between convex portion on the upside of elastic structure is, by the inclination interconnecting part Elastic structure main part is regarded as below center.Between convex portion on the downside of elastic structure main part and elastic structure In the presence of tilt interconnecting part form similarly.)

The subject depth of elastic structure main part 8 is seen as 0.25mm from convex portion 10 on the upside of elastic structure, from elastic construction Convex portion 9 is seen as 0.75mm on the downside of body.

The height of pin clamping duromer 6 is 1.8mm, width 4.0mm.

Size and dimension above etc. is to illustrate, and the present invention is not limited to above-mentioned size.

The width up and down of elastic structure is 3.5mm~10.0mm, preferably 4.0mm~8.0mm, more preferably 4.5mm~ 6.5mm preferably.

The width of elastic structure is 3.5mm~10.0mm, preferably 4.0mm~8.0mm, more preferably 4.0mm~6.5mm compared with It is good.

The width of convex portion is 3.0mm~8.0mm, preferably 3.5mm~7.0mm on the upside of elastic structure, more preferably 4.0mm~ 6.5mm preferably.

The width up and down of elastic structure main part is more than 1.3mm, preferably more than 1.6mm, more preferably more than 1.8mm compared with It is good.

A diameter of 2.0mm~6.5mm of the main diameter of elastic structure main part, preferably 2.5mm~5.5mm, more preferably It is preferable for 3.0mm~5.0mm.

The width up and down of convex portion 10 is set as 0.975mm on the upside of elastic structure.That be because, if more than 2.0mm, then For wide cut (heavy wall), so buckling deformation upward is deteriorated, if below 0.6mm, then convex portion to damage deformation by pressure excessive, to hand The hooking (occlusion) of finger is deteriorated.The width up and down of convex portion 10 is on the upside of the elastic structure of the appropriate buckling deformation of energy acquisition 0.6mm~2.0mm, preferably 0.6mm~1.7mm, more preferably 0.6mm~1.5mm, more preferably 0.7mm~1.2mm Preferably.In addition, the finger hooking position of the lower side of convex portion 10 or finger occlusion position are formed as obtuse angle on the upside of elastic structure Form or acute angle form are preferable, and the obtuse angle form and acute angle form are formed as radius in the case where bending corner shape is Below 0.5mm angle of bend, the good hooking state to finger can be obtained.

In addition, the top profile of convex portion 10 is formed as flexure plane slowly on the upside of elastic structure.Hereby it is achieved that make wherein The function of convex lens that appears larger of pin clamping duromer 6.In addition, by being formed as flexure plane slowly, elasticity is tied The upper lower wall thickness width of convex portion 10 is formed as making to grab the hooking and the preferable thickness of buckling deformation when pinching on the upside of structure body.

Pin clamping duromer 6 uppermost position be located at than elastic structure main part 8 uppermost position more on the lower Side and the larger distance (" characteristic morphology (1) " described later) up and down of distance 1.725mm (more than 0.6mm) position.Thus, bullet Property structure on the upside of convex portion 10 and elastic structure main part 8 1.725mm within position (more than 0.6mm) be formed as not having There is the upside softness tectonic position of the only elastic structure 2 of pin clamping duromer 6.Be formed as on the downside of the position with pin folder Hold the hard tectonic position in downside of duromer 6.

Thus, convex portion 10 and elastic structure main part 8 on the upside of elastic structure are pinched and strengthen this and grab when being grabbed with thumb and forefinger When pinching power, upside softness tectonic position is subject to crushing deformation.Form is pinched using the grabbing for Japanese " Ha " font of its deformation and finger, Make to push away effect and act on convex portion 10 on the upside of elastic structure, the effect of pressing is acted on the hard tectonic position in downside.Also, shape Into the elastic structure main part 8 (hereinafter referred to as " softness construction forms main body section " of upside softness tectonic position.) reason hand The bad effect of extruding caused by referring to, it is above-mentioned above push away effect and the above-mentioned effect of pressing, turn into stretch along the vertical direction stretching form (with Down also referred to as " main part stretching form ".).In addition, elastic structure on the upside of convex portion 10 bottom also turn into be pushed to top and The buckling deformation form of tilting, make the entrance to elastic structure main part 8 of finger and damage easy progress by pressure.

Main part stretching form is that the hard tectonic position in downside where pin clamping duromer 6 is pressed downwards deformation Form, pinch power so grab grabbing for the finger pinched and will not directly act on pin cramping body, or less grab that to pinch power non- Profile.It is thereby achieved that pinch elastic structure when be grabbed with thumb and forefinger and strengthen this and grab and pinch power self-marketing and carry out extraction behaviour When making, it will not directly strengthen the perforation ear pendant buckle of the pin chucking power of pin clamping duromer 6.

Moreover, it is achieved that stretching the buckling deformation form of convex portion on the upside of form and elastic structure using main part, make finger Grab and pinch sense and pinch the good perforation ear pendant card of holding easiness with firm sense of stability, reassurance and grabbing with comfort Button.

It is that the grabbing for Japanese " Ha " font expanded downwards pinches form (" feature shape described later that grabbing of grabbing that knob refers to, which pinches position, State (2) ").Moreover, the construction (as reference, reference picture 5) from above-mentioned " characteristic morphology (1) ", with thumb and forefinger (sometimes Also with middle finger) strongly grab and pinch the form of elastic structure 2 and grab and pinch the strong form of power (including finger finger belly position is grabbed and pinches form ((b) of reference picture 5).), it is that the soft tectonic position in upside is subject to crushing and state that the hard tectonic position in downside is not subject to crushing, institute In the form of grabbing knob and refer to and grab and pinch as Japanese " Ha " font for expanding downward.

It is to go more upward that above-mentioned Japanese " Ha " font, which is grabbed and pinches form, the narrower form of distance between finger.That is more upward Side is gone, and is grabbed and is pinched stronger the grabbing of power and pinch form.Therefore, when Japanese " Ha " font grab pinch enhancing under form grab pinch power when, elasticity knot The position strongly pressed in the position of structure body 2 is that convex portion 10 and elasticity are tied on the upside of the elastic structure of the soft tectonic position in upside Structure phosphor bodies portion 8.When strongly grab pinch the soft tectonic position in upside when, the top of elastic structure 2, which turns into, damages warpage stretching by pressure State, and damage extended state by pressure on the upside of main part extended state in turning into.It is to make to grab to pinch that the upside, which damages extended state by pressure, What power escaped upward grabs effusion state above power of pinching.Grabbed to grab to pinch caused by pinching form as Japanese " Ha " font and escaped above power State, also it is in elastic structure downside convex portion 9 and is not grabbed the state pinched strongly from the side.

According to above-mentioned " characteristic morphology (1) " and " characteristic morphology (2) ", i.e., pressed from both sides using finger from the 1st clamping part and the 2nd The transverse direction for holding the chucking power enhancing in portion is grabbed and pinches elastic structure and strengthen this and grab and pinch power, and the 1st clamping part and the 2nd clamping part are also seldom Or inner side will not be close to substantially.Therefore, grab pinch extraction operation when, selling the chucking power of retaining part will not be remarkably reinforced, Convex portion 10 is also engaged hooking with finger on the upside of elastic structure, is pinched it is achieved that no matter being grabbed from which direction, can be from perforation Ear pendant pin is pulled easily out the perforation ear pendant buckle of elastic structure.

The distance of the uppermost position and the uppermost position of elastic structure main part 8 of pin clamping duromer 6 is 0.6mm Above preferably, preferably more than 0.9mm is preferable, and more preferably more than 1.3mm is preferable, and more preferably more than 1.5mm is preferable.

The obtuse angle position or acute angle position without corner cutting as the lower angle of convex portion 10 on the upside of elastic structure Strengthen the occlusion hooking to finger, it is achieved that the slip difficulty of elastic structure upside convex portion 10, also becomes than the warpage Shape form is big.It is thereby achieved that grab the reduction for pinching power, comfort and grab the raising pinched and keep easiness.Above-mentioned obtuse angle or acute angle It is that radius is angle of bend within 0.3mm or straight cuts are cutting angle within 3mm.

Illustrate the function of convex portion 9 on the downside of elastic structure.

(1) finger tip is deformed laterally using convex portion 9 on the downside of elastic structure, avoid strongly grabbing and pinch on the downside of the elastic structure The sidepiece of convex portion 9, so weakening the influence that duromer 6 is clamped to pin.In addition, abutted using with convex portion 9 on the downside of elastic structure The pressing force of finger tip press convex portion 9 on the downside of the elastic structure downwards, the effect of transverse shear stress is escaped downwards, so Weaken the influence that duromer 6 is clamped to pin.Grabbed using the wall thickness decrease finger of convex portion 9 on the downside of elastic structure and pinch power, decrease pair The influence of pin clamping duromer 6.

(2) more than half of pin clamping duromer 6 is the form in convex portion 9 on the downside of elastic structure, so can utilize Convex portion fully ensures that the sidepiece at the elastomeric construction position for applying active force to pin clamping duromer 6 is thick on the downside of elastic structure Degree.

Thus, part or all that can make the main body fineness degree in elastomer structure phosphor bodies portion 8 is formed as thinner form (bag Include necking part).Such as the main part thinner than the width of pin clamping duromer 6 can also be formed as.By being formed as thinner master Body portion, elastomer structure phosphor bodies portion 8 can be made to be formed as more easily stretchable form.

" pin insertion hole 4 " can also be blind hole form.

" inside it is located on the downside of elastic structure in convex portion 9 or with convex portion 9 on the downside of own elasticity structure across elastic structure main part Pin clamping duromer 6 " is set ... in 8 form, can be formed as the embedded whole in whole positions of pin clamping duromer 6 Form (setting form in whole positions) is buried at position, also there is a part of own elasticity structure main part 8 for making pin clamping duromer 6 The part exposed of bottom expose form of form (form is set in part) etc. etc..

The position of finger abutting portion 11 can be roughly the same with pin clamping duromer 6, or can also be located at than the pin Clamp the position of duromer 6 by the top.Set upward alternatively, it is also possible to the upper edge angle of the convex portion 9 on the downside of elastic structure Prominent small convex portion, it is more easy to feel that finger abuts.

Upper edge angle 16 can be further formed as obtuse angle, to expand finger abutting portion and be easy to feel corner.With Finger, which is gently grabbed, to be pinched the finger finger belly position of elastic structure and grabs and pinch form, can reliably be experienced with the finger tripe of the finger The form of the finger abutting portion of the abutting of the finger abutting portion has various form.

For example, own elasticity structure main part can be exemplified in the form of more than 0.7mm degree is laterally projecting；Figure 10 is set The sentient convex-concave of shown such finger tip, the form of projection；Upper edge more to convex portion on the downside of elastic structure is gone higher Taper form；The fineness degree of elastic structure main part and the relation of the protrusion form of convex portion on the downside of elastic structure；And More than the 1.3mm of elastic structure main part distance etc. up and down.

In the present embodiment 1, elastic structure 2 is made up of transparent silicone rubber component.Inside it is located at elastic structure 2 Interior pin clamping duromer 6 is made up of the gold component of the glossinesses such as gold, white alloy or pink colour gold.Therefore, utilization is transparent Elastic structure 2 can externally visibly sell the clamping color of duromer 6, shape.

Upper portion 21 is that convex lens play function as convex bending slowly, is exaggerated pin clamping duromer 6 therein and sees Arrive.14K etc. marking is implemented to the bottom faces exposed of pin clamping duromer 6, using this expose form can magnifying glass Form reliably confirms.

In the state of pin clamping duromer 6 is placed into mould 60, the silicone rubber compression feeding after melting will be heated and filled out It is charged in mould, so as to form perforation ear pendant buckle 1 (reference picture 6).Nontransparent elastic structure is also contained in the present invention Protection domain in.

Pin clamping duromer is not limited to the noble metal of gold etc., has the steel after titanium, stainless steel, plating, hard to close The diversified form such as resin component.In addition, the form of pin clamping duromer is also not limited to make clamping part from outside The bending shape gone to inner side, such as have various forms such as the form gone from Inside To Outside as shown in Figure 7.

The upper corners of convex portion 9 and lower angle are that 5mm is so small on the downside of bottom interconnecting part 14, elastic structure, so Do not see it being angle of bend visually, obtuse angle can be seen as.I.e., in appearance, bottom interconnecting part 14, elastic structure downside convex portion 9 top linea angulata and lower line can actually be seen in alignment.

It is preferential grab pinch easiness in the case of, be formed as width up and down and the width increase for making elastic structure 2 0.5mm or so, upper and lower width is 5.5mm, the elastic structure for the size that width is 6.0mm is preferable.In this case, it is elastic Convex portion 10, the elastic structure downside width up and down of convex portion 9 and the main body fineness degree of elastic structure main part 8 on the upside of structure It is constant.Therefore, the width up and down of elastic structure main part 8 reaches 2.475mm.As long as at a glance, with regard to slightly larger bullet can be found out Property structure than elastic structure 2 big one enclose.

Due to an overall big circle, and the width up and down of elastic structure main part 8 becomes a length of 2.475mm, is pinched easily so grabbing Property and comfort are more preferable.

Elastic structure can also be the form for only increasing upper and lower width for not changing width.

Fig. 6 represents the mould example of perforation ear pendant buckle 1.

Mould 60 is made up of such as lower part：Upper mould 61, mould 61 forms the upper portion of the topmost as elastic structure 2 on this 21；Middle mould 62, in this mould 62 formed elastic structure on the upside of the whole of convex portion 10, the whole of elastic structure main part 8 and The major part in addition to the position of lower knuckle edge of convex portion 9 on the downside of elastic structure；Lower mould 63, the lower mould 63 form elastic construction The lower knuckle edge position of convex portion 9 on the downside of body.

Middle mould 62 is non-separately mould, is to be provided only with the form to form hole.In addition, the convex portion 9 on the downside of the elastic structure of middle mould 62 And the upper portion of elastic structure main part 8, by SG#116 honing formed with pears surface position 65.Utilize the pear skin The surface of facial position 65 upper portion of convex portion 9 and elastic structure main part 8 on the downside of elastic structure, formed in Fig. 6 It is non-slip parts 21 with the small convex-concave position of shadow representation.

If not being processed by shot blasting (mirror surface treatment) to pears surface position 65, non-slip parts 21 are as transparent component At elastic structure 2, frivolous spray pattern is presented.That is that pin insertion hole 4 in elastic structure 2 can be clearly seen, insert The faint ambiguous morphology of the pin 3 entered.

Non-slip parts 21 play function as the anti-slip component for making to carry out to grab the finger pinched not easy glide, greatly improve elastic construction The grabbing of body 2 pinches the stability of easiness, the weak pins such as the extraction easiness of self-marketing pinched under power of grabbing extract operability.

In the present embodiment 1, after pears surface position 65 is formd by honing, the degree to be disappeared with convex-concave is to pears surface Position 65 carries out mirror finish processing.By so handling, the faint fringe of non-slip parts 21 is eliminated, makes surface that there is light Pool, internal permeability is good, reaches the degree that with the naked eye can not clearly recognize faint fringe.Non-slip parts 21 are formed For the convex-concave position of gloss, function is played as anti-slip component.Also the function of improving the extraction easiness from middle mould 62 is played.

The forcing press for having upper mould 61 and lower mould 63 by self-retaining unloads middle mould 62 to be placed on the fixture of taking-up, Perforation ear pendant buckle 1 is extruded using the top of 1.2mm extrusion pin extruding perforation ear pendant buckle 1, to be located at The taking-up of perforation ear pendant buckle 1 in middle mould 62.

If extrusion pin is more than 1.2mm fineness degree, the amount of compression laterally of elastic structure 2 is larger, and resistance also increases, The deformation of elastic structure 2 after extraction is returned and not gone, and influences initial mode of appearance.

If extrusion pin is below 1.2mm fineness degree, extrusion pin is slipped into pin insertion hole 4, it is impossible to push away pulling out.Consider this It is because the position being connected with convex portion 10 on the upside of the elastic structure of the protruding parts 65 as middle mould 62 implements minute surface and added Work, so both adaptations are high, friction or the effect of sucker are significantly greater.

By setting pears surface position 65, the perforation ear pendant in middle mould 62 are grasped with buckle 1 in the extrusion that 1.2mm extrusion is sold Under work, deformation is also few, will not also occur to the slipping into for extrusion pin of pin insertion hole 4, realize good extrusion.

In the case of 100 that are formed as 10 × 10=100 while the mould of processing, in the absence of pears surface position 65 Mould in, that is, make one to be applied with whole body weight, by 100 extrusion pin carry out extrusion simultaneously do not allow to be drawn out easily yet.Such as By using the punching press of existing 50t levels at one's side, can realize.In contrast, in the mould for being provided with pears surface position 65, People only lightly applies body weight, is easy to extract 100 perforation ear pendant buckles 1.Therefore, higher productivity ratio is realized.

As the distance up and down for removing and expanding the elastic structure main part 52 of form downwards is 4.0mm.Elastic structure master The distance up and down in body portion 52 is preferable for 3.0mm~6mm.Elastic structure main part 52 downwards expand can also than scheme more It is wide.For example, 5.0mm~6.0mm.

Retaining part 6c position is sold positioned at the position within the bottom faces 3.0mm of elastic structure main part 52.It is preferred that Within 2.5mm, within more preferably 2.0mm preferably.

In the present embodiment, the distance up and down of elastic structure main part 52 is set as 4mm, makes pin retaining part 6c's Position is located at the position of the bottom faces 2mm apart from above-mentioned elastic structure main part 52.

The lower side of the interior elastic structure 50 provided with pin clamping duromer 6, be formed as being not easy to send out because the pin clamps duromer 6 The hard construction for the shape that the changes i.e. hard tectonic position in downside, the upper side of the lower side of the elastic structure 50 is elastic construction Convex portion 10 on the upside of phosphor bodies portion 52 and elastic structure, be formed as the upside softness structure being only made up of the elastomeric material of retractility Make position.

The lower side of the interior elastic structure 50 provided with pin clamping duromer 6, is formed as being not easy because the pin clamps duromer 6 And the hard construction that the upper side of the lower side from the elastic structure 50 the deforms i.e. hard tectonic position in downside.

Grabbed with thumb and other fingers and pinch the strength of elastic structure 50 and grab and pinch form, be directed towards the bending shape that lower section expands Two fingers grabbed in the form of Japanese " Ha " font and pinch Japanese " Ha " font of elastic structure and grab and pinch form.Above-mentioned Japanese It is to go more upward that " Ha " font, which is grabbed and pinches form, the narrower form of distance between finger.That is to go more upward, grabs that to pinch power stronger Grab and pinch form.

Therefore, when Japanese " Ha " font grab pinch increase under form grab pinch power when, strongly pressed in the position of elastic structure 50 The position of pressure is the convex portion 10 on the upside of the elastic structure of the top.

Thus, elastic structure upside convex portion 10 is most grabbed by force pinches pressing, and convex portion 10 hooks on the upside of the elastic structure It is hung in the state of finger, finger so need not strongly grab and pinch elastic structure main part 52, the extraction with regard to that can carry out self-marketing Operation.

Therefore, be not likely to produce to pin retaining part 6c position be located at than elastic structure main part 52 central part on the lower The pin clamping duromer 6 of position, the pressing that comes self-marketing retaining part 6c side effect, so will not produce strong to inner side Power extrudes the 1st clamping part 6a and the 2nd clamping part 6b effect, or even if produces, and small pressure.

It is thereby achieved that no matter being grabbed from which direction, pinch can be from the perforation ear pendant buckle that perforation ear pendant pin be pulled easily out.

Embodiment 7

Figure 12 is embodiments of the invention 7, and with being in place of the main difference of above-described embodiment 1, foring makes elastic knot Structure body is the perforation ear pendant buckle 56 of elastic structure 55.

Elastic structure 55 is in elastic structure main part 8 formed with necking part 57.The height of necking part 57 is 1.25mm, main body Width is 2.40mm.Strongly grab pinched elastic structure 55 when, make contracting using the few thinner necking part 57 of elastomeric material Neck 57 easily extends, so can weaken the pressing of the finger to finger abutting portion 11.

Particularly, by the way that elastic structure is formed as into hard material, the distance up and down of thinner necking part 57 is set as 1.0mm~2.5mm, main body fineness degree is set as 1.7mm~3mm, realizes and detect by an unaided eye and apparently stretch Form.

Further, since necking part 57 is relatively thin, so being proximate to the 1st folder to the abutting portion of the finger of finger abutting portion 11 Hold the position of portion 6a and the 2nd clamping part 6b surface.Therefore, finger when pinching is grabbed to the 1st clamping part 6a and the 2nd clamping part 6b Press direction turn into from close to surface top effect.

Thus, strengthening the effect of the pushing from side of the 1st clamping part 6a and the 2nd clamping part 6b pin chucking power will not produce, Or even if producing, it is also weaker.

When be formed as making the top of the 1st clamping part and the 2nd clamping part be located at outside that necking part is formed as into main body is thinner Form when, make to make the 1st clamping part and the 2nd clamping part carry out opening action using pinching is grabbed, or to the 1st clamping part and the 2nd Clamping part applies opening effect, weaken pin chucking power and can also realize can easily self-marketing pull out the form of elastic structure.
