Abstract

PROBLEM TO BE SOLVED: To provide a catch which does not cause difficulty in pulling out because of an extreme increase in pin tightly-holding force at a pin tightly-holding part of a rigid pin catch in an operation of pulling out from a pin by increasing holding force by holding an elastic structure with fingers.SOLUTION: A body part 3 has an L>T configuration, in which a body part front and rear width T is shorter than a body part right and left width L. Because of the L>T configuration, in a right and left holding state in which the body part 3 is held in a right and left direction with fingers, an elastic structure 2 in a held state easily rotates only by a shift operation of both a thumb and an index finger that are holding. Then, the holding state becomes in a front and rear holding state in which the body part 3 is held in a front and rear direction, and tightly-holding force of a tightly-holding rigid body is not increased when holding force is increased, or in the front and rear holding state since the elastic body slips and rotates (especially when a hand fat or the like is attached) in increasing the holding force.SELECTED DRAWING: Figure 1

Description

  The present invention provides a piercing catch that includes a pin catch made of a hard member (gold, etc.) in an elastic structure such as a silicon rubber member. The present invention relates to a catch that does not become difficult to pull out because the pin clamping force of the pin clamping part of the pin catch is increased even if the picking force is increased.

The resin-made elastic body 101 (elastic structure) disclosed in Patent Document 1, which is the prior art shown in FIG. 13, and a metal provided in the resin-made elastic body 101 by integral molding, such as by injection molding The pierced earring catch, which is made of a spring member 102 made of steel, is peeled off.
The elastic body 101 made of resin has a mortar shape with a circular cross section having an annular recess 11 at the center.
The spring member 102 (pin clamping hard body) forms a first clamping part 102a and a second clamping part 102b in which both sides of a single plate material are formed in a curved shape (substantially circular shape) in an upward winding form. It will be.
The side that appears in the form (glasses form) in which two circles that are the edge side of the curved form are arranged is the front and rear sides of the sandwiching body, and the side that appears in the plate form is the left and right sides of the sandwiching body.

  In addition, an elastic structure disclosed in Patent Document 2 in which a pin-clamping hard body is provided has a semispherical sphere or a flat upper surface of the semispherical sphere.

Japanese Patent No. 5041748 Japanese Patent No. 3977591

In the invention of Patent Document 1, when the spring member 102 (pin clamping hard body) is clamped from the left and right sides and the pinching force is increased, the first clamping unit 102a and the second clamping unit 102b are pushed from the left and right. Thus, the pin is moved inward, and the pin clamping force of the pin clamping portion 102c is strengthened so that a pinching force increasing operation state is obtained. In this state where the pinching force is increased, the pulling out from the pin 120 has a strong resistance, and if the pin pinching portion 102c is located in the pin groove 120a or if it is located, the pulling operation becomes extremely difficult. It was.
As a result, there was a risk of damaging the earlobe piercing hole, deforming or damaging the earring decoration, and discomforting the user.

  In addition, since the resin elastic body 101 (elastic structure) has a circular cross section, the resin elastic body 101 has a feeling of rolling (unstable and unreliable) when picked with a finger and has a circular cross section. Therefore, the feeling of touching the finger is not dispersed and concentrated in the area where the finger hits. In other words, it has the disadvantage of poor picking.

  In addition, when there are hand grease, cosmetic oils and the like on the finger, it has a drawback that it easily slides and comes off the finger.

From the above, according to the invention of Patent Document 1, since the cross section of the resin elastic body 101 is circular, the picked portion becomes the pick state determination portion as it is. Therefore, the front and rear sides of the spring member 102 (pin clamping hard body) may be picked or the left and right sides of the spring member 102 (pin clamping hard body) may be picked.
When the left / right picking form is picked up, the pin holding part 102c is in a state where the holding force is increased due to the picking force, and the pin 120 is remarkably difficult to be removed.

  The invention of Patent Document 2 also has the same defects as the invention of Patent Document 1 because the elastic structure has a circular cross section.

  In view of the drawbacks of the prior art as described above, the present invention increases the pin clamping force at the pin clamping portion of the hard pin catch in the operation of removing the pin from the pin by picking the elastic structure with a finger and increasing its picking force. The purpose is to provide catches that do not become difficult to pull out.

In order to achieve the above object, the present invention is configured as follows.
<Invention of Claim 1>
An elastic structure made of an elastic material;
A torso that is a part to be picked with a finger of this elastic structure;
A pin insertion hole for inserting a pin, provided upward from the bottom of the elastic structure;
A first holding part and a second holding part which are provided in the elastic structure and which hold the pin in an inserted state in the pin insertion hole in a facing holding form; and the first holding part; Pin clamping comprising a rigid member in which the clamping operation direction for biasing and clamping the pin of the second clamping part is the left-right direction, and the front-rear direction is a non-operational direction that is not the direction for biasing and clamping the pin A hard body, and
When the torso is pinched with a finger from the left-right direction, which is the clamping operation direction, and the pinching force is increased, the pin clamping force for clamping the pins of the first clamping unit and the second clamping unit is increased. It is a form to strengthen the left and right pinch pinching force,
Even if the torso is pinched with a finger from the front-rear direction, which is the non-operation direction, and the pinching force is increased, the pin clamping force for clamping the pins of the first clamping unit and the second clamping unit is It is a non-reinforcing form that does not strengthen
All or a part of the trunk part has a form (L)> (T) in which the trunk part longitudinal width (T) is shorter than the trunk part lateral width (L),
According to the (L)> (T) form, in the left-right picked state in which the torso is picked from the left-right direction with a finger, the elastic force in the picked state can be obtained by moving the thumb and index finger that are being picked. The structure rotates easily and easily, and the picking state becomes the front / rear picking state where the body portion is picked from the front / rear direction, or when the picking force is increased, the elastic body slides around and the front / rear picking is performed. The catch is characterized by being in a state to be in a state.

The “front / rear picking state” includes an oblique picking state from an oblique front / rear direction, a shifted position picking state in which the thumb and index finger are shifted to the left and right, and the like.
The “body part” includes a form in which all of the elastic structure is a body part, a form in which almost all of the elastic structure is a body part, and a form in which a part of the elastic structure is a body part.
The “slipping operation” refers to an operation of sliding (sliding) the thumb and index finger in opposite directions while holding the catch.

<Invention of Claim 2>
The left and right sides of the portion of the body portion that is in the (L)> (T) form are narrowed toward the outside as the body part longitudinal width (T) is reduced, or the left and right end parts are The catch according to claim 1, wherein the front-rear width (T) of the body portion is narrower than the center side of the body portion.

  The form in which the front and rear width (T) is narrowed includes a form in which the entire side part of the body part is narrowed, a form in which substantially the whole side part of the body part is narrowed, and a form in which a part of the side part of the body part is narrowed. including.

<Invention of Claim 3>
The left end portion and the right end portion of the body portion are different front and rear positions in which one end portion is located on the front side and the other end portion is located on the rear side from the one end portion. The catch according to claim 1 or 2.

<Invention of Claim 4>
The finger hooking protrusion of the protrusion form which the picked-up finger hangs is provided in the upper part side of either the front part side of said trunk part, or the rear part side, or any one upper part side. 3. The catch according to 3.

The present invention has the following effects.
<Effect of the Invention of Claim 1>
(1) Since the torso is in the form of (L)> (T), in the left-right picked state in which the torso is picked from the left-right direction with a finger, it is only necessary to move the picked thumb and index finger to move. The elastic structure in the picked state rotates easily and easily, and the picked state becomes the front / rear picked state in which the body portion is picked from the front-rear direction, or when the picking force is increased, the elastic body Slid around (conspicuous when the finger is greasy) and is in the form of the front and rear picking state.
That is, the pinch state is always a wide front-and-rear direction pinch state, which does not increase the pin clamping force between the first clamping part and the second clamping part even if the pinching force is increased. Since it is a form, even if a pin groove enters the pin clamping portion formed by the first clamping part and the second clamping part, the effect of realizing a catch that does not occur that the pin does not easily come off is achieved. Play.

(2) Because of the wide surface of the wide surface in the front-and-rear direction, strong picking with a high level of stability and security can be achieved, especially in slippery conditions where finger oils and cosmetic oils are on the fingers. There is an effect of realizing a pinching state with a firm feeling of being.

(3) In the picking operation with an actual finger, it is rare to pick the torso from right and left, and there are more left and right pinching forms that are shifted from the right and left. The finger is naturally shifted or caught around, and the front and rear are picked up.

(4) In the operation of picking with an actual finger, picking the wide side is overwhelmingly increased, so that there are few opportunities for left and right picking and the effect of overwhelmingly increasing the number of front and rear picking opportunities is achieved. It is.

<Effects of Invention of Claim 2>
While having the same effect as that of the first aspect of the invention and the form in which the front-rear width (T) on the left and right end sides is narrowed, the elastic structure can be obtained even in a state where the body is picked from right and left. It is a form that is very easy to rotate.
Therefore, there is an effect that the front and rear picking state is more natural.

<Effect of the Invention of Claim 3>
The front and rear positions of the left end and the right end of the torso even when the torso is picked from the left and right in the operation of picking with a finger while exhibiting the same effect as the invention of claim 1 or 2 Therefore, in the state where the thumb and index finger are picked from the left and right, the contact position of the thumb and index finger is a position shifted back and forth. The elastic structure can be rotated naturally only by increasing the squeezing force, or the elastic structure can be rotated as the finger naturally shifts. Therefore, when picked, the effect of inevitably becoming a front and rear picking state is produced.

<Advantageous Effects of Invention>
While having the same effect as the invention of claim 1, 2 or 3, and in the picked state, the finger hooking projection is applied to the finger, so that the picking force is increased and the pulling operation is easy to perform. Even when wearing, it has the effect of making it difficult to slip.

  Embodiments that are the best mode for carrying out the present invention will be described below. However, the present invention is not intended to be limited to these examples. Further, in the description of the embodiments to be described later, the same reference numerals are given to the same components of the above-described embodiments, and the overlapping description is omitted.

  In each figure, members and parts that are visible inside the transparent elastic structure are represented by thin lines.

In the embodiment of the present invention shown in FIGS. 1 and 2, the catch 1 has the following configuration.
Insertion operation into pin PN, which is made of elastic material (here, transparent silicon rubber member) such as silicon rubber member, natural rubber member, synthetic rubber member, elastic synthetic resin member, etc. And an elastic structure 2 for performing a punching operation,
A torso 3 that is a part to be picked by a finger of the elastic structure 2;
A pin insertion hole 4 that is provided upward from the bottom of the elastic structure 2 and is a hole having a smaller diameter than the diameter of the pin PN for inserting the pin PN;
The first sandwiching portion includes a first sandwiching portion 5a and a second sandwiching portion 5b which are provided in the elastic structure 2 and sandwich the pin PN inserted in the pin insertion hole 4 in a facing sandwiching manner. The pinching operation direction for urging and pinching the pin PN of 5a and the second pinching portion 5b is the left-right direction, and the front-rear direction is made of a hard member that is a non-operation direction that is not the direction for urging and pinching the pin PN. A pin sandwiching rigid body 5, and
When the body part 3 is picked with a finger from the left-right direction, which is the holding operation direction, and the picking force is increased, the first holding part 5a and the second holding part 5b are pushed and moved inward by the picking force. , The pinch pinning force is strengthened and the pinch pinching force is strengthened.
Even if the body part 3 is picked with a finger from the front-rear direction, which is the non-operation direction, and the picking force is increased, the first holding part 5a and the second holding part 5b are not moved inward by the picking force. There is no pin pinching force to pinch the pin PN.
The trunk | drum 3 is L> T form whose trunk | drum front-and-back width T is a width shorter than trunk | drum left-right width L,
In the left and right picked state in which the torso 3 is picked from the left and right directions with the L> T form, the picking is performed by slightly moving the picked thumb and index finger slightly (with a sense of feeling). The elastic structure 2 in the state rotates easily and easily, and the picking state becomes the front / rear picking state where the body 3 is picked from the front / rear direction, or the elastic body slides around when the picking force is increased ( In particular, when oil and fat components such as hand fat are attached to the finger, it easily slides around.) It is characterized by being in the form of a front-to-back picking state.

The elastic structure 2 has a straight form (see a front view in the center) that is not uneven or curved in the vertical direction.
As for the dimensions, the left and right width L of the body portion is 6.0 mm, the front and rear width T of the body portion is 2.8 mm, and the height H is 4.2 mm.
The left and right body portions L are also the left and right widths (lateral widths) of the elastic structure 2.
The height H (vertical width) is also the height of the trunk (vertical width, vertical width).

The trunk portion longitudinal width T is preferably 5 mm to 2 mm, preferably 4.5 mm to 2.2 mm, and more preferably 4 mm to 2.5 mm.
The body portion left-right width L is preferably 10 mm to 3.5 mm, preferably 8 mm to 4 mm, and more preferably 7 mm to 4.5 mm.
The height H of the elastic structure 2 is preferably 10 mm to 3.5 mm, preferably 8 mm to 5 mm, more preferably 7 mm to 4 mm.
The body part left-right width L is 1.3 times or more, preferably 1.4 times or more, more preferably 1.5 times or more, and further preferably 1.7 times or more of the body part longitudinal width T.

  The four corners of the elastic structure 2 have a curved corner shape, and when the picked finger is shifted and moved, the cattle easily turns around 1/4 turn, or fat such as hand grease. It makes it easy to slip around when the minute is on.

On the upper side of the front surface of the trunk portion 3 and the upper side of the rear surface, a pear ground 8 having a shape that does not reach the left and right curved side surfaces is provided.
The pear ground 8 has a shape in which the pear ground of the mold to be formed is mirror-finished, so it does not become a cloudy surface but is a pear ground where the transparent interior can be seen through.
A number of fine projections on the pear ground 8 provide a picking feeling that the picked finger is difficult to slip, and the resistance increases, making it easy to perform the pulling operation and lightening the finger without increasing the picking force so much A feeling of unplugging is realized.
The pear ground 8 has various forms such as a form provided on substantially the whole (including the whole) front face and rear face of the body part 3 and a form provided on a central part not provided on the upper part and the lower part.
Moreover, the pear ground 8 is also a form which fulfill | performs the function for making it easy to remove from a metal mold | die easily.

The pin sandwiching rigid body 5 is internally formed by integral molding in a form in which the bottom portion is exposed outside the bottom portion of the elastic structure 2 at the lower portion in the elastic structure 2 and is inserted into the pin insertion hole 4. The first holding part 5a and the second holding part 5b are formed in a curved form (substantially circular form) in an upward winding form on both sides of one plate material. It is made of a hard member (here, a gold member).
It has an integrated structure in which the elastic structure 2 is filled in the first holding part 5a and the second holding part 5b.
The pin clamping rigid body 5 has a bottom base diameter of 2.5 mm, a front / rear width of the first clamping part 5a and the second clamping part 5b of 1 mm, and a height of 2.5 mm, but is limited to this dimension. It is not a thing.

Beads 6 for strengthening the plate are formed in the first clamping part 5a and the second clamping part 5b.
The location where the pin PN of the first clamping portion 5a and the second clamping portion 5b is pinched forms a pin clamping location 5c, and the first clamping portion 5a and the second clamping portion 5b are substantially at the pin clamping location 5c. The contact form or the proximity form.
When the pin PN is inserted into the pin insertion hole 4, the pin PN hits the first holding portion 5a and the second holding portion 5b at the pin holding portion 5c, and if pushed forward, the first holding portion 5a and the second holding portion 5b is placed in the inserted state where the first sandwiching portion 5a and the second sandwiching portion 5b are displaced outwardly against the elastic force of the elastic body 2 of the elastic structure 2.
In the state where the clamping portion is pushed and inserted, the pin clamping portion 5c is hard and does not deform and is in the form of a wide plate. Accordingly, the pin clamping portion 5c is strengthened by the pinching force of the pin PN due to the elastic repulsive force to push back the elastic flesh of the elastic structure 2 and becomes difficult to come off.

When the body 3 is pinched with a finger from the left-right direction, which is the clamping operation direction, and the picking force is increased, the elastic structure 2 is pressed and compressed from the left-right direction to increase its elastic repulsion force. Since the first clamping part 5a and the second clamping part 5b are pushed inward by the elastic repulsive force, the pin clamping force of the pin clamping part 5c that clamps the pin PN is strengthened, so that the pin PN can be removed when the pin PN is removed. Resistance increases.
That is, the picking form from the left-right direction is a left-right picking pinching force strengthening form.

  On the other hand, even if the body part 3 is picked with a finger from the front-rear direction, which is the non-operation direction, and the picking force is increased, the first holding part 5a and the second holding part 5b have an elastic repulsive force of the elastic structure 2. Even if there is an increase, the pin clamping pressure at the pin clamping portion 5c does not increase, that is, the pin clamping force at the pin clamping portion 5c does not increase before and after.

The pin-clamping hard body is not limited to noble metals such as gold and platinum, but has a wide variety of forms such as titanium, stainless steel, plated steel, and hard synthetic resin members.
Further, 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.

(1) Since the torso 3 is in the form of (L)> (T), in the left-right picked state in which the torso 3 is picked from the left and right directions with a finger, it is only necessary to move the picked thumb and index finger to move. The elastic structure 2 in the picked state turns easily and easily, and the picked state becomes the front and rear picked state in which the body part 3 is picked from the front and rear direction, or when the picking force is increased, the elastic body is It is in a form that slides around (especially when a fat component is attached to the finger) and is in the front-rear picking state.
In other words, the pinching state is always a wide front-and-rear direction pinching state, and even if the pinching force is increased, the pin clamping force of the pin clamping portion 5c does not increase, so that the pin PN is removed. A catch that doesn't happen is difficult.
The L> T configuration in which the front-rear width T is shorter than the left-right width L of the body is that the entire body is L> T, almost all of the body is L> T, Some of the parts have L> T form.
(2) Picking with a strong sense of stability and security due to its wide width in the front-and-rear direction, especially in the slippery state where finger oils and makeup oils are attached to the fingers. Realize the state.
(3) In the picking operation with a finger, it is rare to pick the torso 3 from right and left, and there are more left and right pinching forms that are slightly shifted from right and left. This is a misalignment operation or a catch-rotation operation, so that the front-rear picking state is established.
(4) In the picking operation with a finger, picking the wide side is overwhelmingly large, so there are few opportunities for left and right picking, and there are overwhelmingly opportunities for front and rear picking.

In the second embodiment for carrying out the present invention shown in FIG. 3, the main difference from the first embodiment is that the left and right sides of the body portion 3 become narrower as the front and rear width T of the body portion becomes narrower toward the outside. The left and right side portions 9a and 9b are narrow left and right sides 9b, and the positions of the left end 10a and the right end 10b are at one end relative to the center line Y. The portion (here, the left end portion 10a) is located on the front side, and the other end portion (here, the right end portion 10b) is located on the rear side, and the catch 11 is formed in different front and rear positions.
The upper part has a curved convex shape.
Nashiji 8 is not provided.

Since the left and right end portions are narrow left side portion 9a and narrow right side portion 9b, the front and rear width T of the body portion is narrowed. Therefore, even when the body portion 3 is picked from right and left (on the center line Y), the elastic structure The body 2 is in a form that makes it very easy to rotate.
Therefore, the form which becomes a natural picking state more naturally is realized.

  Furthermore, the positions of the left end portion 10a and the right end portion 10b are shifted forward and backward with different front and rear positions where one end portion is located on the front side and the other end portion is located on the rear side from the center line Y. Therefore, the elastic structure is likely to turn naturally only by slightly increasing the pinching force depending on the left and right end deviation state, or the elastic structure turns and becomes a smooth natural displacement movement of the finger. Is. Therefore, when it picks, the form which is inevitably picked up before and after, or the form which becomes very easy is implement | achieved.

In the third embodiment for carrying out the present invention shown in FIG. 4, the main difference from the first embodiment is that the elastic structure and the body are made of an elastic structure 13 of a vertical semicircular disk or a vertical semielliptical disk. In addition, the catch 15 as the body portion 14 is formed.
The left-right part is curved.
The elastic structure 13 and the body 14 are the same.

In the fourth embodiment for carrying out the present invention shown in FIG. 5, the main difference from the first embodiment is that the elastic structure is touched by the finger contact portions 17 a and 17 b where the picked fingers spreading forward and rearward hit the lower portion. The body is formed in the shape of a vertical semicircular disk or a vertical semi-elliptical disk, and the body formed on the upper part of the finger contact portions 17a and 17b is elastically formed as the body 18 having a side surface formed as a curved end. The catch 20 is the structure 19.
The left-right part has a curved shape with a square.
The finger contact portions 17a and 17b with the picked fingers that spread forward and rearward in the lower portion form a wide bottom surface, which makes it easy to sit when placed.
The lower side of the finger contact portions 17 a and 17 b is not included in the body portion 18.

In the fifth embodiment for carrying out the present invention shown in FIG. 6, the main difference from the first embodiment is that the elastic structure and the body are elastic with a planar shape as a rhombus shape and a corner as a curved angle. The catch 24 is formed as the structure 22 and the body 23.
Due to the rhombus form, the picking form is inevitably an oblique front and rear picking form.
All or part of the corners may be acute angles.

  Since the left and right short parts of the rhombus-shaped body are thin and easily deformed, the tip part is deformed and the holding balance is immediately shifted even if the picking force is slightly increased even in the right and left picked state, and the elastic structure 22 It will turn and it will be in the front and rear picking state with safety and stability.

In the sixth embodiment for carrying out the present invention shown in FIG. 7, the main difference from the first embodiment is that an elastic structure and a body portion are provided, and a protruding portion 26a and a protruding portion 26b are provided on the left and right side portions. This is in that a catch 29 serving as an elastic structure 27 and a body portion 28 is formed.
The end portion of the protruding portion 26a, which is the left end portion and the right end portion of the body portion 28, and the end portion of the protruding portion 26b, one end portion (here, the end portion of the protruding portion 26a) is located on the front side and the other end portion The end portions (here, the end portions of the protruding portions 26b) are different front and rear positions located on the rear side.
The left and right widths of the thick portion of the body portion 28 can be shortened by the protruding portions 26a and 26b.

  Since the end portion of the projecting portion 26a and the end portion of the projecting portion 26b have different front and rear position forms that are displaced forward and backward from the center line Y, the elastic structure can be obtained by slightly increasing the pinching force depending on the left and right end portion misalignment state. Is a natural turning movement that is natural, or the finger moves smoothly and naturally, and the elastic structure 27 turns. Therefore, when it picks, the form which is inevitably picked up before and after, or the form which becomes very easy is implement | achieved.

  Since the protrusion 26a and the protrusion 26b are thin and easily deformed, the tip portion is deformed and the holding balance is immediately shifted and the elastic structure 27 is rotated by merely slightly increasing the picking force even in the right and left picking state. , Will be in a safe and stable front and rear picking state

In the seventh embodiment for carrying out the present invention shown in FIG. 8, the main difference from the first embodiment is that the elastic structure and the trunk portion are obliquely cut on the left and right side portions with half or more cut diagonally. It is in the point which formed the catch 33 used as the elastic structure 31 and the trunk | drum 32 made into the form.
The positions of the left end 34a and the right end 34b are such that one end (here, the left end 34a) is located forward of the center line Y and the other end (here, the right end 34b). It is set as the form which shifted | deviated before and after making it the different front-back position located in the back side.
The elastic structure is likely to rotate naturally only by slightly increasing the pinching force depending on the left and right end shift states, or the elastic structure is rotated due to a smooth natural displacement movement of the finger. Therefore, when it picks, the form which is inevitably picked up before and after, or the form which becomes very easy is implement | achieved.
In the side part oblique form, a part of the side part may be an oblique form, or the whole side part may be an oblique form.

  In the eighth embodiment for carrying out the present invention shown in FIG. 9, the main difference from the first embodiment is that the trunk portion has a trunk portion 36 having a thin front-rear width T with a shorter front-rear width T and a lower side. The catch 39 of the form which becomes the elastic structure 38 formed by forming the lower protrusions 37a and 37b in the form of leaving the point is formed.

The front-rear width T of the body portion is about 0.3 mm thicker than the front-rear width of the pin clamping hard body 5. Here, the body front-rear width T is set to 1.6 mm.
Since the front-rear width T of the trunk portion is 1.6 mm, which is a thin-walled shape, the side meat of the trunk portion 36 is deformed and the pressing balance is immediately shifted even if the picking force is slightly increased even in the right and left pinching state, and the elastic structure 38 It will turn and it will be in the front and rear picking state where the picking is stable and stable.
