Abstract

PROBLEM TO BE SOLVED: To provide a piercing catch in which an increase in pin clamping force at a pin clamping portion does not occur at the time of pinching operation from a pier spin. SOLUTION Even when the picking force is remarkably increased, it is the upper soft structure part that is crushed and deformed. Therefore, the first pinching portion 6a and the second pinching portion 6b in which the pin pinching portion 6c in the lower stiff structure portion is positioned below the finger contact portion 11 are hardly affected. Therefore, the urging / clamping force of the pin clamping part 6c hardly increases, and no remarkable resistance is generated in the pulling operation from the pin. [Selection] Figure 1

Japanese Patent No. 5041748

  Hereinafter, the elastic body <9> made of resin is placed on the sides of the first curved portion <4a> (first clamping portion) and the second curved portion <4b> (second clamping portion) (in FIG. 13). A state that occurs when the thumb and index finger are picked from the right side and the left side will be described (see FIG. 13).

≪Catch <A> ≫
A pin elastic state <9> in which the pin <7> is inserted into the pin insertion hole <10> is picked with the thumb and forefinger "hereinafter" pick "," pick "," pick "or" pick ""I picked it." ) The pinching form of the resin elastic body <9> at the time of pulling out from the pin <7> is as follows.
Since the catch <A> is as small as 5.4 mm x 4.0 mm for the small catch and 6.7 mm x 5.0 mm for the large catch, both fingertips of the picked fingers are below the lower curved convex part <e>. The lower convex portion is in a state of being picked over the top and is in a pinching form.
The reason for this lower convex finger gripping configuration is that (a) the lower corner (lower edge) of the lower curved convex portion <e> has a radius (R) of 1.0 mm for a small catch, and a radius (R) for a large catch. (B) The upper curved convex part <d> and the lower curved convex part <e> have the same thickness, and (c) the upper and lower parts of the annular concave part <11>. The width is as narrow as 1.1 mm to 1.3 mm, and (d) the ring-shaped concave portion <11> is smoothly connected to the upper curved convex portion <d> and the lower curved convex portion <e>. This is because the resin-made elastic body <9> having a small vertical distance of 4 mm to 5 mm when viewed from the finger is a straight structure having a curved lower corner shape with respect to the finger to be picked.
When picking a small catch <A> of 4 mm to 5 mm of a straight structure with a curved lower corner, the lower side where the finger hook is the largest in order to prevent the resin elastic body <9> from coming off the finger This is also a pinching operation in which the fingertip is strongly applied to the inwardly inclined surface below the maximum projecting portion of the curved convex portion <e>.
Thus, when pulling out the pin from the catch <A>, by holding the catch <A> with the fingertip strongly applied to the inwardly inclined portion of the lower part of the lower curved projection <e>, The pulling operation can be easily performed.

The upper curved convex portion <d> is a moderately curved projection shape having a radius (R) of 0.9 mm for a small catch and a radius (R) of 1.0 mm for a large catch and no obtuse angle.
Such a thick and gently curved curved protrusion form has little crushing deformation even when the finger picking force is increased, and deformation that warps upward and escapes hardly occurs due to slippage due to gentle bending. Is. Therefore, the finger also does not escape upward, so that the fit is poor and the finger is positioned at the position of the lower curved convex portion <e> and the spring member <1> (pin clamping hard body). It will be picked strongly.

Therefore, when the picking force of the picked finger is increased, the upper soft structure portion (upper curved convex portion <d>) portion is slightly crushed and deformed, and the lower stiffened structural portion (annular concave portion <11> and lower curved convex portion is formed. The portion <e>) is smaller or hardly deformed than the upper curved convex portion <d>.
If the picking power is increased as it is, naturally the catch <A> is pushed out from the finger (moving out of the finger).
In order to stop the pushed-out movement, the lower stiff structure portion (particularly, the lower curved convex portion <e>) is strongly picked, and the finger is turned to the lower side of the lower curved convex portion <e>. It becomes a picking operation.
And if the lower stiff structure part (especially lower curved convex part <e>) side is picked strongly, the pushing force from the both side parts to the spring member <1> located inside will become strong, This is a pin clamping force increasing operation in which the pin clamping force of the pin clamping portion <4c> of the curved convex portion <d> and the lower curved convex portion <e> is remarkably increased, and the operation resistance pulled out from the pin is remarkably increased. is there.

The catch <A> is as small as 4 mm to 5 mm. In the operation of picking the catch and pulling out the pin, the annular recess <11> has a large radius (R) of 0.9 mm and a large radius when the catch is narrow and the curvature angle is small. Since the catch is a gentle curve connection with the upper curved convex portion <d> having an obtuse angle with a radius (R) of 1.0 mm, the fingers are weakly hooked on the upper curved convex portion <d>. Therefore, the upper curved convex portion <d> has a weak function as a finger hook portion (excluding the nail hook) where the finger meat is applied.
Further, when picked without placing a finger on the lower surface of the lower curved convex portion <e>, or side surfaces of the upper curved convex portion <d>, the annular concave portion <11>, and the lower curved convex portion <e> In the case of picking with only a finger, the catch <A> easily slips off from the finger when the picking force is increased.

The catch <A> is a form in which the spring member <1>, which is a hard member, is positioned on the body of the resin elastic body <9>, and the uppermost position of the spring member <1> is annular. From the uppermost position of the recess <11>, the small catch is 0.25 mm and the large catch is 0.27 mm (elastic structure body), which is an extremely narrow arrangement.
For this reason, the annular recess <11> (elastic structure body) as a whole has a hard structure by the spring member <1>, and the lower curved convex portion <e> located in the spring member <1>. Is also a harder structural part.

That is, the annular concave portion <11> where the hard spring member <1> is located and the lower curved convex portion <e> form a lower rigid structural portion, and the upper curved convex portion <where the spring member <1> is not disposed < The d> part forms the upper soft structure part and is the part that communicates with the lower hard structure part of the upper soft structure part and the uppermost position of the spring member <1> and the uppermost part of the annular recess <11>. The catch separation section at the upper position (= the lowermost position of the upper curved convex portion <d>) has a narrow catch separation distance of 0.25 mm for the small catch and 0.27 mm for the large catch.
For this reason, the catch <A> is such that the narrow catch separation section is hardly stretched by the picking force, and the upper curved convex portion <d> is less likely to cause upward escape deformation, In the operation of strengthening the pinching force of the finger, the lower stiff structure portion is also strongly picked, and the pin pinching force increasing operation in which the pin pinching force of the pin pinching portion <4c> is remarkably increased is performed.

Regarding the catch <B>, in paragraph [0018] of Patent Document 1, “when receiving the pin <7>, the annular recess <11> formed on the outer periphery of the catch is pinched with the tip of a fingertip or nail. Is possible. "
However, in fact, even if an attempt is made to place a fingertip (fingertip meat) in the annular recess <11> without placing a finger on the lower surface of the lower curved projection <e>, if the picking force is increased, Because it slips down, it is difficult to remove the pin by finger picking.
On the other hand, when the thumb nail and the index finger nail are put in the annular recess <11> and picked, the catch can be picked relatively firmly, and the extraction operation can be easily performed.
Therefore, in both the catches <A> and <B>, the annular recess <11> functions as a “nail catching part” or “nail picking part” and does not function as an “pointing part” on the finger meat. It is a considerable thing to be.

People with long nails and people with long nails attached to the nails are difficult to pick with their fingertips or nails. (Refer to figure (b)). ) And removing / attaching from the pin.
In such a finger flank portion picking form, the catches <A> and <B> are pushed out of the finger and fall off when the picking force is increased as described above.

≪About Catch <B> ≫
In the catch <B> of Patent Document 1, the sandwiched portion <4c> at the substantially vertical center position of the first curved portion <4a> and the second curved portion <4b> is the center of the annular recess <11>. The position is substantially the same as the position <C>. The uppermost part of the spring member <1>, which is the uppermost part of the first curved part <4a> and the second curved part <4b>, is located above the annular concave center position <C>.

  Further, the uppermost part of the spring member <1> in the resin elastic body <9> is located above the uppermost position of the annular recess <11>. The position is 0.43 mm for the large catch and 0.37 mm for the small catch.

Therefore, in the vicinity of the annular recess <11> where the spring member <1> is located, the hard spring member <1> has a hard central structure that is difficult to deform.
Even in such a configuration in which the spring member <1> is located at the center, the inward pressing force by the picking force when the catch <B> is picked acts strongly on the spring member <1>. Therefore, the pin clamping force increasing operation is the same as that described in the above catch <A>.

  In view of the drawbacks of the prior art as described above, the present invention makes it difficult to remove the pin from the pin when the elastic structure is picked with a finger and the pin is pulled from the pin with a strong picking force. It aims to provide a piercing catch that never happens.

It is a catch for piercings of Claims 1-4 or 5 characterized by the above-mentioned.

The present invention has the following effects.
<Effect of the Invention of Claim 1>
(1) The uppermost position of the pin clamping hard body is a wide vertical distance located 1 mm or more (three times or more of the prior art) below the uppermost position of the elastic structure body.
Therefore, the 1 mm or more site | part of an elastic structure upper side convex part and an elastic structure body part forms the upper soft structure structure part only of an elastic structure without a pin clamping hard body. The lower side forms a lower stiff structure portion having a pin clamping hard body.
Therefore, when the elastic structure upper convex part and the elastic structure body part are picked with the thumb and forefinger and the picking force is increased, the upper soft structure part is crushed and deformed, and the elastic structure upper convex part is pushed up. The elastic structure body part (hereinafter referred to as “soft structure forming body part”) that forms the upper soft structure part has a crushing action by a finger. By the push-up action and the push-down action, an extension form (hereinafter referred to as “body extension form”) extending in the vertical direction is obtained.
In addition, the lower part of the upper protrusion of the elastic structure is also pushed upward to be warped and escaped.

In the trunk extension configuration, the lower stiff structure portion where the pin clamping hard body is located is configured to be pushed downward, so that the pinch finger picking force may directly act on the pin clamping hard body. There is no or small clamping force non-operational form.
Therefore, when pinching the elastic structure with the thumb and forefinger and pulling it out of the pin by increasing its picking force, it realizes a piercing catch that does not directly increase the pin clamping force of the pin clamping body Yes.
In addition, the gripping feeling with the picking finger is realized by the body stretch form, and the catch for piercing with a sense of stability, security, and easy to hold with a good fit is realized.

In addition to the fingertip picking form, the catching thumb and index finger picking form includes a finger flank part picking form.
This is a finger flank portion picking form in which the nails are not picked by the fingertips due to a long or long nail, etc., and the flank portions of the thumb and forefinger where the nails do not touch each other are picked (see FIG. 5 ( b)).
Even in such a finger flank region picking form, the present invention realizes a good gripping and easy removal.

<Effects of Invention of Claim 2>
The vertical width of the elastic structure upper convex portion is 0.6 mm to 2.0 mm, and the elastic structure upper convex portion has an obtuse angle portion or an acute angle portion that is applied to a finger, and the obtuse angle portion and the acute angle When the portion has a curved angle form, the radius is 0.5 mm or less.
Therefore, when the obtuse angle part or the acute angle part of the convex part on the upper side of the elastic structure increases the picking force of the finger, the finger is further bitten, and it is in a state of strong friction that is hard to slip. Due to this strong hooking state, the upper convex portion of the elastic structure having a vertical width of 0.6 mm to 2.0 mm is warped upward (in the figure) and escapes upward, and the finger gripping portion is separated from the pin clamping hard body by the warpage escape distance. It becomes a finger escape form to leave. This finger escape form avoids the direct pinching of the pin clamping hard body, and realizes a piercing catch that does not directly increase the pin clamping force of the pin clamping body. In addition, the picking power is reduced, and the fit feeling and the ease of picking are improved.

<Effects of Invention of Claim 3>
The upper and lower width of the elastic structure body is 1.3 mm or more, and the uppermost position of the pin-clamping hard body is located below the center position of the elastic structure body.
Therefore, the distance between the elastic structure body and the uppermost position of the pin clamping hard body is 0.65 mm or more (1.3 / 2). The distance of 0.65 mm or more is twice or more the distance of 0.27 mm for the large catch of the invention of Patent Document 1 and 0.25 mm for the small catch.
That is, since the vertical distance of the upper soft structure portion without the pin-clamping hard body of the elastic structure body is as long as 0.65 mm or more, the upper soft structure structure portion is easily stretched. By increasing the gripping force of the finger by the form in which the upper softening structure part is easy to extend, the upper softening structure part is extended, and the finger picking part is separated from the pin clamping hard body by the extended distance. Become. This finger escape form avoids the direct pinching of the pin clamping hard body, and realizes a piercing catch that does not directly increase the pin clamping force of the pin clamping body. In addition, the picking power is reduced, and the fit feeling and the ease of picking are improved.

<Effects of Invention of Claim 4>
The same effect as that of the first or third aspect of the invention can be achieved.

<Effect of the Invention of Claim 5>
In addition to the same effects as the first to third aspects of the invention, the following effects can be obtained.
(1) Since the fingertip is relieved to the outside by the elastic structure lower convex part and it is avoided to strongly pick the side part of the elastic structure lower convex part, the influence on the pin clamping hard body is weakened. .
Further, the elastic structure lower convex portion is pushed down by the pressing force of the fingertip that hits the elastic structure lower convex portion, and the side pushing action is released downward, so the influence on the pin clamping hard body is weakened. .
The finger thickness is reduced by the lateral wall thickness of the lower convex portion of the elastic structure, and the influence on the pin clamping hard body is reduced.

(2) Since more than half of the pin-clamping hard body is located on the lower convex part of the elastic structure, the thickness of the side part of the elastic structure part that applies an urging force to the pin-clamping hard body is set to the lower convex part of the elastic structure. It can be sufficiently secured by the part.
Accordingly, a part or all of the body thickness of the elastic body body can be made into a thin form (including a constriction) without considering the strength around the pin clamping hard body. For example, it is possible to make the body thinner than the lateral width of the pin-clamping hard body.
By using a thin body portion, the elastic body body body portion can be made easier to stretch and have a larger elongation.

<Effect of the invention of claim 6, wherein>
While exhibiting the same effect as that of the invention according to claims 1 to 4 or 5, the anti-slip portion formed of fine irregularities formed on the surface of the upper convex portion of the elastic structure is less likely to slip the finger and to hold the finger. Therefore, the ease of picking and the ease of pulling out are greatly improved.
Further, in the form formed by the non-divided middle mold and the lower mold in which the upper mold, the elastic structure upper convex part and the elastic structure body part are formed, the ease of extraction from the middle mold is realized.

The upper end surface of the lower protrusion 9 of the elastic structure, the connecting surface of the upper surface and the elastic structure body 8, or the fingertip of the finger picking up the elastic structure 2 composed of the upper surface and the connecting surface is used. Part 11 per finger to stop;
For pinning up the plate, the pin 3 inserted in the pin insertion hole 4 is inserted in the pin insertion hole 4 in a state of being sandwiched between the half or more in the elastic structure lower convex portion 9 and is integrally formed. A pin clamping rigid body 6 made of a rigid member having a first clamping part 6a and a second clamping part 6b in which a bead 15 is formed;
It has a configuration including a pin clamping portion 6c that is a portion for pinching the pin 3 of the first clamping portion 6a and the second clamping portion 6b.

The first clamping part 6a and the second clamping part 6b are an integral structure in which the elastic structure 2 is filled and adhered, including the inside and the periphery.
As a result, the inserted pin 3 is inserted by pushing the first holding part 6a and the second holding part 6b laterally outward.
When the pin 3 is inserted, the first sandwiching portion 6a and the second sandwiching portion 6b, which are hard members, are opened and moved in the laterally outward direction while deforming the elastic structure 2 without being deformed.
The elastic structure 2 is in a state in which an elastic push-back force that tries to push back the first sandwiching portion 6a and the second sandwiching portion 6b with its elastic repulsion force is always applied, and the first sandwiching portion is caused by this elastic push-back force. The clamping force which clamps 6a and the pin 3 of the 2nd clamping part 6b is strengthened.

Since the elastic structure 2 has a cylindrical shape, the lateral width of each part is a diameter.
The dimensions of the elastic structure 2 are a vertical width of 5.0 mm and a horizontal width of 5.5 mm.
The elastic structure lower convex portion 9 has a vertical width of 1.8 mm (1.55 + 0.25), a horizontal width of 5.5 mm, and a curved cut of the upper edge angle 16 is an obtuse angle of R0.25 mm.
The upper connecting part 7 has a vertical width of 0.55 mm.
The vertical width of the lower connecting part 16 is 0.5 mm.
The elastic structure upper projection 10 has a vertical width of 0.975 mm and a horizontal width of 5.0 mm.
The elastic structure body 8 has a vertical width of 2.55 mm and a body diameter of 4.5 mm. (A mode in which there is an inclined connecting portion (including a curve) between the elastic structure body and the upper protrusion of the elastic structure is an elastic structure body below the center position of the inclined connecting portion. The same applies to a configuration in which there is an inclined connecting portion between the body portion and the lower convex portion of the elastic structure.)
The body depth of the elastic structure body 8 is 0.25 mm from the elastic structure upper protrusion 10 and 0.75 mm from the elastic structure lower protrusion 9.
The pin clamping hard body 6 has a height of 1.8 mm and a width of 4.0 mm.

The present invention is not limited to the above dimensions.
The height of the elastic structure is 3.5 mm to 10.0 mm, preferably 4.0 mm to 8.0 mm, and more preferably 4.5 mm to 6.5 mm.
The lateral width of the elastic structure is 3.5 mm to 10.0 mm, preferably 4.0 mm to 8.0 mm, and more preferably 4.0 mm to 6.5 mm.
The lateral width of the upper protrusion of the elastic structure is 3.0 mm to 8.0 mm, preferably 3.5 mm to 7.0 mm, more preferably 4.0 mm to 6.5 mm.
The height of the elastic structure body portion is 1.3 mm or more, preferably 1.6 mm or more, more preferably 1.8 mm or more.
The thickness of the elastic structure body portion is 2.0 mm to 6.5 mm in diameter, preferably 2.5 mm to 5.5 mm, and more preferably 3.0 mm to 5.0 mm.

The elastic structure upper convex portion 10 has a vertical width of 0.975 mm.
If it is 2.0 mm or more, it is wide (thick) and the upward warping escapes worse, and if it is 0.6 mm or less, the crushing deformation of the convex part is too large and the hooking on the finger (bite) worsens. It is.
The upper and lower widths of the upper protrusion 10 of the elastic structure that can obtain an appropriate warp escape are 0.6 mm to 2.0 mm, preferably 0.6 mm to 1.7 mm, more preferably 0.6 mm to 1.5 mm, The thickness is preferably 0.7 mm to 1.2 mm.
Further, it is preferable that the finger catching portion or the finger biting portion on the lower side of the elastic structure upper convex portion 10 has an obtuse angle shape or an acute angle shape, and the obtuse angle shape and the acute angle shape have a radius of 0.5 mm or less in a curved angle shape. It is possible to obtain a good hooking state on the finger by setting the bending angle.

  The top form of the upper protrusion 10 of the elastic structure is a gently curved surface. This fulfills the function of a convex lens in which the pin pinching rigid body 6 inside can be seen larger. Moreover, by making it a gentle curved surface, the upper and lower wall thickness width of the elastic structure upper convex portion 10 is set to a thickness that is suitable for hooking and warping escape during picking.

(1) The uppermost position of the pin clamping hard body 6 is a wide vertical distance located 1.725 mm below (0.6 mm or more) from the uppermost position of the elastic structure body 8.
Therefore, the 1.725 mm portion (0.6 mm or more) of the elastic structure upper convex portion 10 and the elastic structure body portion 8 becomes the upper soft structure portion of only the elastic structure 2 without the pin clamping hard body 6. Yes. The lower side is a lower stiff structure portion having a pin clamping hard body 6.
Therefore, when the elastic structure upper convex part 10 and the elastic structure body part 8 are picked with the thumb and forefinger to increase the picking force, the upper soft structure part is crushed and deformed. Due to the deformation and the C-shaped shape of the fingers, the elastic structure upper convex portion 10 has a push-up action, and the lower hard structure portion has a push-down action. The elastic structure body part 8 (hereinafter referred to as “soft structure forming body part”) forming the upper soft structure part extends in the vertical direction by the crushing action by the finger, the pushing-up action, and the pushing-down action. It becomes an elongated form (hereinafter also referred to as “trunk stretched form”). In addition, the lower part of the upper protrusion 10 of the elastic structure also has a warp escape form in which the upper structure is pushed upward to make it easier for the finger to enter and collapse the elastic structure body 8.

In this body extension form, the lower stiff structure portion where the pin clamping hard body 6 is located is pushed downward and the picking force of the picked finger acts directly on the pin clamping body. There is no or small picking force non-acting form.
Therefore, when catching the elastic structure with the thumb and forefinger to increase the picking force and pulling it out of the pin, a pinching catch that does not directly increase the pin clamping force of the pin clamping hard body 6 is realized. doing.
In addition, the grip of the pierced ear with a sense of stability, a sense of security, and a fit that is easy to hold with a sense of grip is ensured by the body stretch form and the warp relief form of the upper protrusion of the elastic structure. Realized.

(2) The picking part of the picking finger is a C-shaped picking form that spreads downward. In addition, from the structure of (1) (see FIG. 5 for reference), the elastic structure 2 is placed with the thumb and index finger (in the case of the middle finger) In addition, the pinch strength strengthening form (including the finger lateral abdominal part picking form (see FIG. 5B)) is a form in which the upper soft structure part is collapsed and the lower hard structure part is included. Since the pin is not crushed, the pinch finger has a C-shaped pinch shape spreading downward.

The C-shaped picking form is a form in which the distance between fingers becomes narrower as it goes upward. It is a picking form in which the picking power increases as it goes upward.
Therefore, when the picking force is increased in the C-shaped picking form, the elastic structure upper convex part 10 and the elastic structure body part 8 of the upper soft structure part are strongly suppressed by the part of the elastic structure 2. When the upper soft structure portion is strongly picked, the upper part of the elastic structure 2 is in a state of being crushed and warped and stretched, and is in an upper state of being crushed and stretched. This upper side crushing extension state is a state in which the picking force is released upward to release the picking force upward. Even in the state where the picking force is released upward by the C-shaped picking form, the elastic structure lower convex portion 9 is not strongly picked from the side.

Even if the elastic structure is picked up with a finger from the lateral direction in which the holding force of the first holding part and the second holding part is increased by the above (1) and (2), The one clamping part and the second clamping part are less likely to approach the inside, or hardly.
Therefore, the pinching force at the pin clamping portion does not remarkably increase during the pinching operation, and the elastic structure upper convex portion 10 may bite into the finger, so that it can be easily pulled out of the pier spin from any direction. A piercing catch that can be used.

  The distance between the uppermost position of the pin clamping hard body 6 and the uppermost position of the elastic structure body 8 is preferably 0.6 mm or more, preferably 0.9 mm or more, more preferably 1.3 mm or more. More preferably, it is 1.5 mm or more.

Since the obtuse angle part or the acute angle part without the corner cut which is the lower corner of the elastic structure upper convex part 10 strengthens the biting into the finger, the elastic structure upper convex part 10 is difficult to slip, and its warpage escapes. The form is also larger.
Therefore, a reduction in the picking power, an improvement in fit and ease of picking are realized.
The obtuse angle or acute angle is a bending angle within a radius of 0.3 mm or a cutting angle within a straight cut of 3 mm.

The function of the elastic structure lower convex part 9 will be described.
(1) Since it is avoided that the fingertip is released to the outside by the elastic structure lower convex portion 9 and the side portion of the elastic structure lower convex portion 9 is strongly picked, the influence on the pin clamping hard body 6 Is weakened.
Further, since the elastic structure lower convex portion 9 is pushed downward by the pressing force of the fingertip hitting the elastic structure lower convex portion 9 and the side pushing action is released downward, the influence on the pin clamping hard body 6 is affected. Is weakened.
The pointing force is weakened by the thickness of the lower protrusion 9 of the elastic structure, and the influence on the pin clamping hard body 6 is weakened.
(2) Since more than half of the pin sandwiching hard body 6 is positioned on the lower convex portion 9 of the elastic structure, the side thickness of the elastic structure part that applies a biasing force to the pin sandwiching hard body 6 is determined as the elastic structure. It can be sufficiently secured by the lower convex portion.
Thereby, a part or all of the body thickness of the elastic body body body portion 8 can be made into a thin form (including a constriction). For example, it is possible to make the body narrower than the lateral width of the pin sandwiching rigid body 6.
By setting it as a thin trunk | drum, the elastic body structure trunk | drum 8 can be made into the form which extends more easily.

The “pin insertion hole 4” may have a blind hole shape.
“Pin clamping rigid body 6, which is provided in the elastic structure lower convex portion 9, or is provided in a form extending from the elastic structure lower convex portion 9 to the elastic structure body portion 8”. May be all-embedded form in which all the parts are buried (all-parts-embedded form), or partly exposed form (part-part-built-in form in which a part is exposed from the bottom of the elastic structure body 8) ) And the like.

The position of the part 11 per finger may be substantially the same as or higher than the pin clamping hard body 6.
Moreover, it is good also as providing the small convex part which protrudes upwards in the upper edge angle of the elastic structure lower side convex part 9, and making it easy to feel finger contact.

It is preferable that the upper edge angle 16 is a more obtuse angle so that the part around the finger becomes wider and the angle can be easily felt.
There are various forms of the per finger area where the elastic structure can be lightly picked with a finger and the finger pad of the finger can surely feel the hit of the per finger area.
For example, a form projecting laterally by 0.7 mm or more from the elastic structure body part, a form provided with irregularities and protrusions felt by the fingertips as shown in FIG. 10, and higher as it goes to the upper edge of the lower convex part of the elastic structure Examples thereof include a taper configuration, a relationship between the thickness of the elastic structure body portion and the protruding shape of the lower protrusion of the elastic structure body, a vertical distance of 1.3 mm or more of the elastic structure body portion, and the like.

In the first embodiment, the elastic structure 2 is made of a transparent silicon rubber member.
The pin clamping hard body 6 provided in the elastic structure 2 is made of a glossy gold member such as gold, white gold or pink gold. Therefore, the pin clamping hard body 6 can be seen from the outside by its transparent elastic structure 2.
The upper part 21 functions as a convex lens having a gentle convex curve, and shows the pin pinching hard body 6 inside.
The exposed bottom surface of the pin-clamping hard body 6 is marked with 14K or the like, and can be surely confirmed with a loupe depending on the exposed form.
The piercing catch 1 is formed by heat-melted silicon rubber being compressed and fed into a mold with the pin clamping hard body 6 set in the mold 60. (See Figure 6)
Non-transparent elastic structures are also included in the technical scope of the present invention.

The pin-clamping hard body is not limited to noble metals such as gold, but has a wide variety of forms such as titanium, stainless steel, plated steel, and hard synthetic resin members.
Moreover, the form is not limited to the curved form in which the sandwiching portion is directed from the outside to the inside, and there are various forms such as a form from the inside to the outside as shown in FIG.

  The upper corners and lower corners of the lower connecting portion 14 and the elastic structure lower convex portion 9 appear to be obtuse angles, which are visually invisible as a bending angle, since they are as small as 5 mm. In other words, the upper corner lines and the lower lines of the design, substantially the lower connecting portion 14 and the elastic structure lower convex portion 9 appear as one straight line.

When priority is given to the ease of picking, it is preferable that the elastic structure 2 has a large elastic structure 2 with a vertical width of 5.5 mm and a horizontal width of 6.0 mm, with the vertical width and horizontal width increased by about 0.5 mm.
In this case, the vertical width of the elastic structure upper protrusion 10 and the elastic structure lower protrusion 9 and the body thickness of the elastic structure body 8 are not changed. Therefore, the vertical width of the elastic structure body portion 8 is 2.475 mm.
At first glance, an elastic structure larger than that of the elastic structure 2 appears to be slightly larger.
Since the whole is enlarged one by one and the vertical width of the elastic structure body portion 8 is as long as 2.475 mm, the gripping and the fit feeling are better.
A configuration in which only the vertical width without changing the horizontal width is also possible.

FIG. 6 shows an example of a molding die of the piercing catch 1.
The mold 60 includes an upper mold 61 that forms the upper part 21 that is the uppermost part of the elastic structure 2, all of the elastic structure upper protrusion 10, all of the elastic structure body 8, and lower elastic structure protrusion. 9 includes a middle die 62 that forms most of the lower curved edge portion except the lower curved edge portion 9 and a lower die 63 that forms the lower curved edge portion of the lower convex portion 9 of the elastic structure.
The middle mold 62 is a non-split type and is simply a form in which a formation hole is provided.
In addition, a satin portion 65 is formed by SG # 116 honing at the upper portion of the elastic structure lower projection 9 and the elastic structure body 8 of the middle mold 62.
Due to the satin portion 65, a non-slip portion 21 is formed on the surface of the upper portion of the lower protrusion 9 of the elastic structure and the upper portion of the elastic structure body 8, which is a minute convex recess expressed by hatching in the drawing. Yes.

If the polishing process (mirror surface process) is not performed on the satin-finished area 65, the anti-slip area 21 looks thin and cloudy in the elastic structure 2 that is a transparent member. That is, the pin insertion hole 4 in the elastic structure 2 and the inserted pin 3 are in a mortar cloud form.
The anti-slip portion 21 functions as an anti-slip function, making it difficult for the picked finger to slip, and greatly improves the pin pulling operability such as the stability of the ease of picking of the elastic structure 2 and the ease of pulling out from the pin with a weak picking force. .

In the first embodiment, after the matte region 65 is formed by honing, the matte region 65 is mirror-polished to such an extent that unevenness is not lost.
By doing so, the lightly clouded state of the non-slip portion 21 is eliminated, the surface is glossy and the internal transmission is good, and the frosted state cannot be clearly recognized with the naked eye.
The non-slip portion 21 is in the form of a glossy concave, but functions as a non-slip. The ease of removal from the middle mold 62 also functions.

The piercing catch 1 in the middle die 62 is taken out by removing the middle die 62 from the press machine to which the upper die 61 and the lower die 63 are fixed, setting it in a jig for taking out, and placing the upper portion of the piercing catch 1 on the 1 It is done by pushing and pushing with a 2mm push pin.
If the extrusion pin has a thickness of 1.2 mm or more, the pushing amount to the outside of the elastic structure 2 is large, the resistance increases, the deformation of the elastic structure 2 after being pulled out does not return, and the original design form is damaged. It is.
If the extrusion pin has a thickness of 1.2 mm or less, the extrusion pin enters the pin insertion hole 4 and cannot be extruded.
This is presumably because the portion on which the upper protrusion 10 of the elastic structure, which is the protruding portion 65 of the middle mold 62, is mirror-finished, so that the close contact between them is extremely high and the frictional or sucker action is extremely large.
By providing the matte portion 65, the piercing catch 1 in the middle mold 62 is excellently extruded by pushing out the 1.2 mm push pin, and hardly deforms and does not cause the push pin to enter the pin insertion hole 4. Is realized.

However, when 100 molds with 10 × 10 = 100 are used, with a mold having no satin portion 65, simultaneous extrusion with 100 extrusion pins is easy even if a person puts the whole weight on it. I can't escape. For example, it was possible by using a familiar 50t class press.
On the other hand, in the mold provided with the satin portion 65, 100 people can be easily extracted all at once even if the person applies light weight. Therefore, high productivity is realized.

In the second embodiment of the present invention shown in FIG. 7, the main difference from the first embodiment is that a piercing catch 17 having a pin clamping hard body 19 as a pin clamping hard body 19 is formed.
The pin clamping hard body 19 includes a base portion 18 having a pin through hole 13, a first clamping portion 19a in which the left side of the base portion 18 is bent upwards inwardly and the tip is bent outwardly in an inclined linear form, The right side of the portion 18 is bent upward on the inner side, and the tip of the second holding portion 19b is bent in the form of an inclined straight line, and the pin 3 of the first holding portion 19a and the second holding portion 19b is pinched. It consists of a pin clamping part 19c.

The lower connecting portion is a lower connecting portion 20 that is a right angle corner.
As a result, the vertical distance of the elastic structure body 8 is 2.225 mm.

The uppermost position of the pin clamping hard body 19 is located below the trunk center position C of the elastic structure trunk 8.
The part 11 per finger | toe is located above the pin clamping location 19c.
The pin clamping part 19c may be positioned above the part 11 per finger in a range where the uppermost position of the pin clamping hard body 19 is located below the trunk center position C of the elastic structure body part 8.

In the third embodiment of the present invention shown in FIG. 8, the main difference from the first embodiment is that the elastic structure is an elastic structure 29 and the entire pin clamping hard body 6 is embedded in the elastic structure 29. The point is that the piercing catch 30 is formed.
The elastic structure 29 includes an elastic structure body 31, an elastic structure upper protrusion 32 wider than the elastic structure body 31 formed on the elastic structure body 31, and an elastic structure body An elastic structure lower convex portion 33 that is wider than the elastic structure body portion 31 formed below the elastic member 31 and narrower than the elastic structure upper convex portion 32 is formed.
In the lower part of the elastic structure 29, a guiding part 34 for guiding the pin 3 communicating with the pin through hole 13 to the pin through hole 13 is formed.
The middle mold to be formed is a split mold.

The finger contact portion 35 on the upper side of the lower protrusion 33 of the elastic structure has an obtuse angle that is a substantially right angle and is located above the pin clamping portion 6c, and the entire pin clamping hard body 6 is the elastic structure 29. It is said to be inside.
In addition, the lower edge angle 27 and the upper edge angle 28 of the elastic structure upper convex portion 32 have two obtuse angles called obtuse angles.
The vertical width (thickness) of the upper protrusion 32 of the elastic structure is 0.8 mm (within a range of 0.6 mm to 2.0 mm).

In the fourth embodiment of the present invention shown in FIG. 9, the main difference from the first embodiment is that a piercing catch 37 having an elastic structure 38 as an elastic structure 38 is formed.
An elastic structure 38 made of an elastic material such as a silicon rubber member, a natural rubber member, a synthetic rubber member, or an elastic synthetic resin member;
From a rigid member having a first clamping part 6a and a second clamping part 6b, which is provided in the elastic structure 38 and clamps the pin 3 inserted in the pin insertion hole 4 in a facing clamping manner. A pin sandwiching rigid body 6 and
An elastic structure body 41 of the elastic structure 38;
An elastic structure upper convex portion 10 on which a finger holding the elastic structure 38 is formed on the upper side portion of the elastic structure body 41;
An elastic structure lower small-diameter portion 40 having a smaller diameter than the elastic structure body 41 formed on the lower side of the elastic structure body 41;
A lower finger hook portion 42 composed of the lower edge angle of the elastic structure body portion 41, and
The first sandwiching part 6a and the second sandwiching part 6b are located in the elastic structure lower small diameter part 40,
The position of the pin clamping portion 6c is located below the boundary between the elastic structure lower-side small-diameter portion 40 and the elastic structure body 41,
The upper and lower width of the elastic structure body portion 41 is 1.5 mm, but it is preferably 1.4 mm or more, preferably 1.7 mm or more, more preferably 1.9 mm or more.

The finger that picks up the elastic structure 38 does not reach the elastic structure lower small-diameter portion 40 that is recessed in the lowermost part, or the picking force does not act strongly even if it reaches.
And since the finger picked including the finger lateral abdominal part picking form becomes a two-point picking form in which the two points of the elastic structure upper convex part 10 and the lower finger catching part 42 bite, the friction is large even if it is not picked strongly. Can be easily removed.
Moreover, the influence of the picking force on the first holding part 6a and the second holding part 6b is made small by the form that does not have to be strongly picked.
And since the pin clamping location 6c does not reach the picking action or is located in the small elastic structure lower side small diameter portion 40, the pin clamping location 6c is not restrained from the side, or is extremely small. Therefore, the pinching force of the pin clamping portion does not increase significantly during the picking operation.

In the fifth embodiment of the present invention shown in FIG. 10, the main difference from the first embodiment is that the elastic structure is an elastic structure 44 and the pin clamping hard body 6 is entirely embedded in the elastic structure 44. The pierce catch 45 is formed.
In the elastic structure 44, the upper protrusion of the elastic structure is an upper protrusion 46 of an elastic structure having a single pointed side, and the elastic structure body 47 is a constricted elastic structure body 47. .
It is the constricted portion 47a of the elastic structure body portion 47 that extends most by the picking operation.
The lower inclined surface of the constricted portion 47 a of the elastic structure body portion 47 becomes a finger contact portion 48.
The elastic structure lower convex portion 9 has a small edge angle and is formed with a finger contact projection 49 protruding upward, so that the finger can surely feel that the finger has hit.
The waist diameter of the constricted portion 47a is 3.0 mm, but may be 2.0 mm to 3.5 mm.

An upper recess 43 is provided on the upper portion of the elastic structure 44. When the picking force is increased, the upper side of the upper protrusion 46 of the elastic structure is easily crushed and deformed.
Moreover, the acute angle part which is a side protrusion part of the elastic structure upper side convex part 46 has a curved angle form with a radius of 0.3 mm (a radius of 0.5 mm or less).
Only the upper and lower molds may be used.

  In the sixth embodiment of the present invention shown in FIG. 11, the main difference from the first embodiment is that the elastic structure is an elastic structure 50 having no elastic structure lower convex portion, and the elastic structure body is an elastic structure. The point is that a piercing catch 51 as the body trunk portion 52 is formed.

  The elastic structure 50 has a vertical distance of 3.5 mm to 8.5 mm. Preferably it is 4.0 mm-7.5 mm, More preferably, 4.5 mm-6 are good.

The elastic structure body 52 that expands in the downward direction has a vertical distance of 4.0 mm. The vertical distance of the elastic structure body 52 is preferably 3.0 mm to 6 mm.
The downward expansion of the elastic structure body 52 may be made wider than the figure. For example, 5.0 mm to 6.0 mm.

  The position of the pin clamping portion 6 c is located within 3.0 mm from the bottom surface of the elastic structure body portion 52. Preferably it is within 2.5 mm, more preferably within 2.0 mm.

(1) The vertical distance of the elastic structure body 52 is set to 4 mm, and the pin clamping portion 6 c is positioned 2 mm from the bottom surface of the elastic structure body 52.
The lower side of the elastic structure 50 in which the pin clamping hard body 6 is provided is a lower stiffening structure portion that is a hard structure that is hard to be deformed by the pin clamping hard body 6, and the upper side thereof The elastic structure body 52 and the elastic structure upper convex part 10 are upper soft structure parts made of only a stretchable elastic material.

The lower side of the elastic structure 50 in which the pin holding hard body 6 is provided is a lower hard structure portion that is a hard structure that is harder to deform than the upper side by the pin holding hard body 6.
The strong picking form of the elastic structure 50 with the thumb and other fingers is a C-shaped picking form in which both fingers in a curved form spread downward and the elastic structure is picked up with a C-shaped form. The C-shaped picking form is a form in which the distance between fingers becomes narrower as it goes upward. It is a picking form in which the picking power increases as it goes upward.
Therefore, when the picking force is increased in the C-shaped picking form, the portion that is strongly restrained by the portion of the elastic structure 50 is the uppermost elastic structure protrusion 10.

Therefore, the elastic structure upper convex part 10 is most strongly suppressed and the elastic structure upper convex part 10 is hooked on the finger, and the finger does not pinch the elastic structural body part 52 so strongly. The unplugging operation will be performed.
Therefore, it is difficult for the pin clamping part 6c to be restrained from the side of the pin clamping part 6c to the pin clamping hard body 6 positioned below the central part of the elastic structure body part 52. The action of strongly pressing the first clamping part 6a and the second clamping part 6b inward does not occur, or even if it occurs, it is a slight pressure.
Therefore, the piercing catch that can be easily removed from the pier spin from any direction is realized.

FIG. 12 shows a seventh embodiment of the present invention, which is mainly different from the first embodiment in that a piercing catch 56 having an elastic structure as an elastic structure 55 is formed.
The elastic structure 55 forms a constricted portion 57 in the elastic structure body portion 8.
The constricted portion 57 has a height of 1.25 mm and a trunk width of 2.40 mm.
When the elastic structure 55 is strongly picked by the thin constricted portion 57 with a small amount of elastic material, the constricted portion 57 is easily extended, so that the finger pressing against the finger contact portion 11 can be weakened.
In particular, the elastic structure is made of a hard material, and the thin constricted portion 57 has a vertical distance of 1.0 mm to 2.5 mm and a body thickness of 1.7 to 3 mm. Realize.

Further, since the constricted part 57 is thin, the contact part of the finger to the part 11 per finger becomes a part close to directly above the first holding part 6a and the second holding part 6b.
Therefore, the pressing-down direction of the first clamping part 6a and the second clamping part 6b by the finger at the time of picking is an action from above close to the top.
Therefore, the pressing action from the side that strengthens the pin clamping force of the first clamping part 6a and the second clamping part 6b does not occur and is weak even if it occurs.

  If the top part of the first sandwiching part and the second sandwiching part are located outside, and the constricted part is made into a more narrow shape, the first sandwiching part and the second sandwiching part are opened by the picking operation. Alternatively, it is also possible to form the first holding portion and the second holding portion with an opening action so that the pin holding force is weakened so that the pin can be easily removed from the pin.

  An elastic structure lower-side small diameter portion having a smaller width than the width of the elastic structure body portion formed on the lower side of the elastic structure body portion;
  A lower finger hooking portion on which a finger gripping the elastic structure is formed, comprising a lower edge of the elastic structure body portion, and
  All or a part of the first clamping part and the second clamping part are located in the small diameter part on the lower side of the elastic structure,
  The position of the pin clamping part, which is a part for clamping the pin of the first clamping part and the second clamping part, is located below the boundary between the lower diameter part of the elastic structure body and the elastic structure body part. ,
  The piercing catch, wherein the elastic structure body has a vertical width of 1.5 mm or more.
  The finger that has picked up the elastic structure does not reach the lower small diameter portion of the elastic structure that is recessed inside the lowermost part, or even if it reaches, the picking force does not act strongly.
  And since the picked finger has a pinching form in which two portions of the elastic structure upper convex portion and the lower finger hooking portion bite into, the picking finger can be easily pulled out because the hooking friction is large even if it is not strongly picked.
  Moreover, the influence of the picking force on the first holding part and the second holding part is made small by the form that does not need to be strongly picked.
  And since the pin clamping part is located below the boundary between the elastic structure lower small diameter part and the elastic structure body part, there is no restraining action from the side of the pin clamping part, or it becomes extremely small. The pinching force at the pin clamping portion does not increase significantly during the picking operation.

  The present invention is used in industries that manufacture and use jewelry.
