This application incorporates Japanese Patent Application No. 2004-012452 filed on Jan. 20, 2004 herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a fastener for use in an ornament that includes the fastener.
2. Description of the Related Art
Conventionally, in a fastener for use in an ornament, for example, in a pierced earring fastener (pierced earring fastener), a silicone rubber having rubber elasticity is formed in a cylindrical shape, a spherical shape, or a semispherical shape and the like, and a through hole is provided along a center axis thereof. In such a pierced earring fastener, after a shaft-shaped pin of a pierced earring has been inserted into an earlobe, the pin is inserted into a through hole of the pierced earring fastener, and is used as a pierced earring fastener. However, because the silicone rubber is soft, there has been a problem that a pinching force of the fastener is lost within a short period of time; and the fastener is lost or cannot be used properly. Therefore, the Inventor proposed a fastener such as a pierced earring fastener formed by covering a spherically or cylindrically-shaped pinching member for pinching the pin of the pierced earring with a rubber-like member (refer to patent document 1).
Patent Document 1
Japanese Patent Application Laid-open No. 2000-125911
According to the fastener disclosed in patent document 1, pinching capability of a pin (pinched portion) can be continuously maintained, and predetermined advantageous effect have been successfully attained in improvement of durability. However, the rubber-like elastic member is easily expanded due to aging. Therefore, there is a risk that the pinching capability of the pin is lowered, and the fastener drops. Such aging can occur, of course, when mounting and demounting actions are repeated, and even while the pin is inserted in the through hole and maintained there.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a fastener and an ornament, the fastener being capable of restricting lowering of pinching capability of a pinched portion due to aging of a rubber-like elastic member, and promoting further improvement of durability, the ornament including the fastener.
In order to solve the above described problem, according to a first aspect of the present invention, there is provided a fastener comprising: a rubber-like elastic member that is formed essentially of a rubber or a soft synthetic resin, the elastic member being elastically deformable; and a restraining member that is capable of binding elastic deformation of the rubber-like elastic member in a state in which at least a part of the periphery of the rubber-like elastic member is surrounded, the restraining member having hardness which is equal to or greater than that of the rubber-like elastic member, wherein a part of an ornament is pinched by the rubber-like elastic member, thereby binding and retaining the ornament.
According to such a fastener, a part (pinched portion) of an ornament is pinched by a rubber-like elastic member; elastic reactive force (i.e., spring constant) is enhanced by a restraining force of a restraining member, whereby an ornament can be bound and retained by the thus enhanced elastic reactive force. In this manner, the lowering of the pinching capability of the pinched portion due to aging of the rubber-like elastic member is suppressed by means of the restraining members making it possible to improve durability. The rubber-like elastic member and the restraining member can be configured integrally by means of two-color molding, for example.
In order to solve the above described problem, according to a second aspect of the present invention, there is provided a fastener comprising: a rubber-like elastic member that is formed essentially of a rubber or a soft synthetic resin, the elastic member being elastically deformable; a pinching member that is harder than the rubber-like elastic member, the pinching member being retained at a predetermined position so as to be enveloped by the rubber-like elastic member in a state in which at least a part is embedded in the rubber-like elastic member, the pinching member capable of moving in an expanding direction with elastic deformation of the rubber-like elastic member; and a restraining member that is capable of restricting movement of the pinching member in an expanding direction and elastic deformation of the rubber-like elastic member, the elastic deformation being caused by such movement, in a state in which at least a part of the periphery of the rubber-like elastic member is surrounded, the restraining member having hardness which is equal to or greater than that of the rubber-like elastic member, wherein a part of an ornament is pinched by the rubber-like elastic member, thereby binding and retaining the ornament.
According to such a fastener, a part (pinched portion) of an ornament is pinched by a pinching member; movement of the pinching member is limited by means of a restraining force of the restraining member; and elastic reactive force (i.e., spring constant) is enhanced by means of a restraining force of a restraining member, whereby an ornament can be bound and retained by means of the thus enhanced elastic reactive force. In this manner, the lowering of the pinching capability of the pinched portion due to aging of the rubber-like elastic member is suppressed by means of the restraining member, making it possible to improve durability.
In these fasteners, a part of the ornament is formed as a shaft-shaped member so that the restraining member can cover the rubber-like elastic member to be surrounded along a circumferential direction of the shaft-shaped member. In this manner, the shaft-shaped member such as a pin is indirectly tightened by means of the restraining member via the rubber-like elastic member (or via the rubber-like elastic member and the pinching member) so that the pinching capability is maintained over a long period of time, and the durability of the fastener is improved.
At this time, if the restraining member covers the rubber-like elastic member in a ring shape, the rubber-like elastic member binds all of elastically deformable directions so that the shaft-shaped member can be pinched evenly in a circumferential direction. Therefore, in the case where the rubber-like elastic member has a through hole or a bottomed hole that permits insertion of the shaft-shaped member, the wear of these holes can be homogenized.
As described above, the restraining member is formed of a material having hardness equal to or greater than that of the rubber-like elastic member, for example, a metal (14KP gold, for example), a resin, or a hard rubber and the like. In addition, the restraining member has a function of pinching (tightening) a part (pinched portion such as a shaft-shaped member) of an ornament via the rubber-like elastic member (or via the rubber-like elastic member and a pinching member). Therefore, if the minimum inner diameter of a ring-shaped restraining member is formed to be smaller than the maximum outer diameter of the rubber-like elastic member, the restraining member can be prevented from coming off of the rubber-like elastic member or the restraining member can be firmly tightened and retained with the rubber-like elastic member, like a tightening engagement.
In addition, when the pinching member is comprised of a plurality of elements, a part of an ornament is directly pinched between elements of the pinching member or is indirectly pinched via another member. In addition, the elastic reactive force of the rubber-like elastic member is enhanced by means of the restraining force of the restraining member and movement of the pinching member is limited by means of the thus enhanced elastic reactive force so that the ornament can be bound and retained. At this times when a plurality of elements of the pinching member are arranged in parallel in a state in which two cylinders are coupled integrally with each other or in a state in which they are independent of each other, a part of the ornament is pinched in a gap defined between the cylinders of the pinching member; the elastic reactive force of the rubber-like elastic member is enhanced by limiting movement of the pinching member by means of the restraining force of the restraining member so that the ornament can be bound and retained by thus enhanced elastic reactive force.
In this way, the pinching member is made of a material that is harder than the rubber-like elastic member (for example, a metal), and is provided as a member for pinching a part of the ornament between the elements. For example, a spherical body, a columnar body, a modified spherical body having a plane provided partly of the spherical body, and other variously formed elements are assembled and formed so as to be proximate to each other.
In addition, the rubber-like elastic member is provided as a member for directly imparting an elastic force for binding a part of the ornament or for indirectly imparting the force via a pinching member. For example, this elastic member has a through hole or a bottomed hole that permits insertion of a part of the ornament, and is formed of a material having rubber elasticity such as silicone rubber, urethane rubber, acrylic rubber or the like. Also for example, when a pierced earring pin (shaft) is inserted while shifting a position of the pinching member and expanding the hole, an elastic reactive force is applied to an orientation such that the pinching member is restored at its predetermined position, and then, the pin is indirectly pinched via the pinching member. At this time, an expanding portion serving as an introducing portion may be provided at an end of a hole for inserting the pin. Further, when that hole is formed as a bottomed hole, a distal end of the pin is protected by means of the rubber-like elastic member and the distal end of the pin does not protrude, so that the appearance is improved and no contacts to human body occur. In addition, in the case where this hole is formed as a through hole, the top and bottom of the fastener cannot be discriminated, and there is no need of confirmation of the top and bottom at the time of wearing. Thus, the fastener can easily be used. In addition, the fastener is formed to be large sized, so as to be used with a chain being inserted as a necklace fastener or the like. Further, the rubber-like elastic member can be formed of a perspective, for example, transparent or semitransparent material so that a pinching member, at least a part of which is embedded therein, can be externally positively viewed. In this manner, ornament property can be improved.
In addition, in order to solve the above described problem, according to a third aspect of the present invention, there is provided an ornament comprising; a fastener configured as described above; a main body; and a pinched portion to be pinched by means of the fastener at the main body side thereof.
As described above, there can be provided a further high quality ornament capable of preventing a loss of a fastener, improving durability of the whole ornament, and achieving a further high quality by the improvement of durability of the fastener.
In such an ornament, an auxiliary ornament member other than a main body and/or an auxiliary fixing member other than a fastener can be mounted on a restraining member of the fastener. In the case where the auxiliary ornament member is mounted on the restraining member of the fastener, an ornament effect (for example, a back pierced earring mode) can be added to the fastener in addition to the ornament effect of the main body (for example, front pierced earring mode). Further, in the case where the auxiliary fixing member is mounted on the restraining member of the fastener, a loss expensive jewelry or the like mounted as an auxiliary ornament member can be prevented. A method for mounting an auxiliary ornament member and/or an auxiliary fixing member on a restraining member of a fastener can include means such as brazing, adhesive bonding, or engagement with a recessed portion. Specifically, the restraining member of the fastener can have a mounting portion (such as a hook) for mounting an auxiliary ornament member other than the main body and/or an auxiliary fixing member other than the fastener. In this way, as long as the restraining member of the fastener has a mounting portion such as a hook, these auxiliary ornament member and auxiliary fixing member can be easily mounted. The mounting portion is composed of a material identical to that for the restraining member. After the fastener has been assembled, the mounting portion can be fixed by being brazed with the restraining member positioned at the outermost part or by other method.
The ornament used here includes a pierced earring, an unpierced earring, a broach, a necklace, a bracelet, or an anklet and the like. A relationship between a main body and a fastener in an ornament according to the present invention can be expressed as follows:
(1) In a pierced earring or a broach and the like, a pierced earring fastener (pierced earring fastener) or a broach fastener may have an essential function of a fastener for fastening a shaft-shaped member of a main body through an earlobe or fabric on the back or may have a function of mounting an auxiliary ornament member or an auxiliary fixing member on the main body.
(2) In an unpierced earring or the like, an unpierced earring fastener is used in the case where it has a function of mounting an auxiliary ornament member or an auxiliary fixing member on a main body instead of a function for retaining the main body of the unpierced earring on an ear.
(3) Fasteners of a necklace, a bracelet, or an anklet and the like have a function of folding a string-like chain to be halved, both ends of which are inserted to form a ring; moving a position against the chain of a main body to be slid; and adjusting the size of the ring.

BEST MODE FOR CARRYING OUT THE INVENTION
First Embodiment
Now, embodiments of the present invention will be described with reference to some examples shown in the accompanying drawings. FIG. 1A and FIG. 1B each show a first embodiment of each of a pierced earring fastener serving as a fastener according to the present invention and a pierced earring as an ornament. A pierced earring fastener 1 (fastener) comprises: a pinching member 2 comprised of three (a plurality of) balls 2a, 2a and 2a; a ball holder (holder) 3 that is a rubber-like elastic member; and a ring 5 (restraining member) for tightening the pinching member 2 and the holder 3.
The three balls 2a, 2a and 2a are disposed in a ring shape at intervals of 120 degrees in a circumferential direction, as elements constituting the pinching member 2. These balls are retained at their predetermined positions by means of the holder 3. The ball 2a is formed in a spherical shape, of a hard metal material (for example, stainless steel). The holder 3 is formed in a cylindrical shape, of a material having rubber elasticity such as silicone rubber. This holder completely surrounds the ring-shaped pinching member 2 constituted by the three balls 2a. A through hole 3a penetrating the center of both of end faces 3c and 3c is formed via a gap 2b defined at a center of the ring made by the pinching member 2 contained therein. In the vicinity of each of the ends of the through hole 3a, an introducing portion 3b each expanding the diameter in a tapered shape is formed toward each of the end faces 3c, thereby guiding insertion of a shaft-shaped member included in an ornament such as a pierced earring pin or a broach pin. The ring 5 is made of metal material (for example, 14KP gold) that is harder than the holder 3 and is formed into a ring shape. This ring binds from outside the movement in an expanding direction (radial direction) of the pinching member 2 (balls 2a, 2a and 2a) and elastic deformation of the holder 3 due to that movement. In this manner, the ring 5 covers externally in a ring shape the periphery in a radial direction in which the holder 3 is elastically deformable.
In a pierced earring 19 (main body), an ornament portion 19a is formed integrally with a proximal end of a shaft-shaped pin 4. (shaft-shaped member or pinched portion). The pierced earring fastener 1 is inserted through a proximal end side of the pin 4, and pinches the pin 4 in a state in which the fastener is engaged with a peripheral groove 4a formed in the vicinity of a distal end thereof. At this time, by means of the restraining force of the ring 5, movement of the pinching member 2 is limited, and then, the elastic reactive force of the holder 3 is enhanced. In this manner, the pin 4 of the pierced earring 19 is bound and retained by means of the thus enhanced reactive force, and then, the pin 4 is pinched between the balls 2a, 2a and 2a. As shown in FIG. 1B, the minimum inner diameter of the ring 5 is formed to be smaller than the maximum outer diameter of the holder 3. In the insertion direction of the pin 4, a width of the ring 5 is formed to be smaller than that of the holder 3 so that the ring 5 hardly comes off an engagement groove 3e defined on a circumferential face of the holder 3 and the holder 3 and the pinching member 2 are strongly tightened externally.
In the pierced earring fastener 1, while the holder 3 for binding the pinching member 2 in a covering state may be colored with appropriate color, the pinching member 2 embedded therein can be viewed in a perspective manner if the fastener is transparent or semitransparent. Thus, an ornamental value can be added to the fastener 1 by beauty in terms of the design, that is, the shape of the element 2a of the pinching member 2 and its assembled mode.
Here, effects (function) of the pierced earring fastener 1 will be described with reference to FIG. 2. As shown in steps (a) and (b) of FIG. 2, a distal end of the shaft-shaped pin 4 of the pierced earring 19 is inserted into the through hole 3a via the introducing portion 3b. In order to expand the gap 2b, while the ball 2a is moved in an expanding direction, the pin 4 is advanced straight inside of the through hole 3a. Concurrently, the holder 3 is pushed to be expanded, and a side face 3d is about to protrude to the outside. Namely, the balls 2a moves to the outside in a radial direction (indicated by the arrow in step (b)), whereas the holder 3 is elastically deformed.
At this time, as shown in step (c) of FIG. 2, the ring 5 serves to restrict movement of the balls 2a by means of its restraining force and to improve a spring constant (elastic reactive force) obtained when the holder 3 is elastically restored by means of a reaction. By the thus enhanced elastic reactive force (reaction force), the holder 3 compresses and pinches in a state in which it surrounds the pin 4 via each of the balls 2a (as indicated by the arrow in step (c)). In the pin 4, the small diameter portion (circumferential groove) 4a is defined at a pinched portion thereof, and then, such balls 2a pinch the pin 4 in a state that each of the balls 2a is engaged with this circumferential groove 4a. Namely, after a distal end of the pin 4 has advanced to push the three balls 2a in a expanding direction, if the circumferential groove 4a reaches a pinching portion of the three balls 2a, these three balls 2a slightly return in a diameter-reducing direction, and stays in the circumferential groove 4a. In this manner, the pin 4 is positioned and pinched. Here, stepped portions 4b and 4c at both sides of the circumferential groove 4a function to position the pin 4. In particular, 4b serves to prevent the pin 4 from coming-off of the three balls 2a.
In addition, the introducing portion 3b provided at each end of the through hole 3a formed at the holder 3 may be formed in a curved shape instead of forming it to be expanded in a diameter direction in a tapered shape. One end or both ends of the through hole 3a can be formed without being expanded in a diameter direction. The shape of the ends of such a through hole 3a is applicable to all of the embodiments which will be described later. However, as shown in FIG. 2, in the case of the pierced earring fastener 1 used as a pierced earring fastener, it is desirable to provide the introducing portion 3b for guiding the pin 4 at each end of the through hole 3a so that the pin 4 can easily be inserted through both sides regardless of the top and back.
FIG. 3 shows a method for manufacturing such pierced earring fastener 1. As shown in FIG. 3, the three balls 2a, 2a and 2a (pinching member 2) are inserted into a die, and then, a silicone rubber is injected and insertion-molded, thereby forming the holder 3 that has the through hole 3a in an axial direction and the engagement groove 3e on a circumferential face. In addition, the circularly annular ring 5 is cut and formed. Next, when an inner periphery face of the ring 5 is engaged into the engagement groove 3e of the holder 3, the pierced earring fastener 1 is completed.
FIG. 17A and FIG. 17B each show a modified example of FIG. 3. As shown in step (a) of FIG. 17A, the three balls 2a, 2a and 2a (pinching member 2) are inserted into a die, and then, a silicone rubber is injected and insertion-molded. In this manner, the holder 3 (rubber-like elastic member) is formed, the holder having the through hole 3a in an axial direction and exhibiting a lens shape the center part of which is thick and a peripheral part of which is thin. In addition, the circularly annular ring 5 as shown in step (b) of FIG. 17A is formed by means of cutting or the like. At this time, a cross section of the ring 5 is formed into a protrusive mountain-like shape (inverted V-shape) toward the outside, and the minimum inner diameter of the ring 5 is formed to be smaller than the maximum outer diameter of the holder 3 (refer to FIG. 17B). Next, as shown in step (c) of FIG. 17A, the holder 3 is engaged so that an outer face of the holder 3 can be received on the mountain-shaped inner periphery face of the ring 5, and the pierced earring fastener 1 is completed.
Second Embodiment
FIG. 4A and FIG. 4B each show a second modified example of a pierced earring fastener. In FIG. 4A and FIG. 4B, the pinching member 2 is comprised of the two balls 2a and 2a opposed to each other in a circumferential direction at an interval of 180 degrees.
Third Embodiment
FIG. 5A and FIG. 5B each show a third embodiment of a pierced earring fastener. In FIG. 5A and FIG. 5B, the pinching member 2 is comprised of two cylinder bodies 2a′ and 2a′ integrally coupled with each other. At the time of insertion molding of the holder 3, silicone rubber is filled inside of the cylinder bodies 2a′ and 2a′. In addition, an upper end face 3c′ of the holder 3 is formed into an upwardly protrusive dome shape. In the second embodiment (FIG. 4A and FIG. 4B) and the third embodiment (FIG. 5A and FIG. 5B), constituent elements having functions common to those of the first embodiment (FIG. 1A to FIG. 3) are designated by the same reference numerals, and the descriptions are omitted.
Fourth Embodiment
FIG. 6A and FIG. 6B each show a fourth embodiment of a pierced earring fastener. A pierced earring fastener 11 (fastener) shown in FIG. 6A and FIG. 6B is equipped with: the ball holder (holder) 13 that is a rubber-like elastic member; and a ring 15 (restraining member) for restraining the holder 3. This pierced earring fastener is not equipped with the pinching member 2 of the first embodiment (FIG. 1A and FIG. 1B).
The holder 13 is formed in a cylindrical shape, of a material having rubber elasticity such as of a silicone rubber, for example, and the through hole 13a penetrating a center of both of the end faces 13c and 13c is formed. The introducing portion 13b expanding the diameter in a tapered shape toward each of the end faces 13c is formed in the vicinity of each end of the through hole 13a, thereby guiding insertion of an axial member included in an ornament such as a pierced earring pin or a broach pin. The ring 15 is made of a metal material (for example, 14KP gold) that is harder than that of the holder 13 and formed in an annular shape, and binds elastic deformation of the holder 13 from outside. In this manner, the ring 15 externally covers in an annular shape the periphery in a radial direction in which the holder 13 is elastically deformable. Therefore, an elastic reactive force of the holder 13 is enhanced by means of a restraining force of the ring 15, and a pin 4 (refer to FIG. 1A) of the pierced earring 19 is bound and retained. Then, the pin 4 is pinched by means of the holder 13.
Fifth Embodiment
FIG. 7A and FIG. 7B each show a fifth embodiment of a pierced earring fastener. In FIG. 7B, a sectional shape of the holder 13 is formed in an elliptical shape made of the two curved faces 13f and 13f. In addition, a sectional shape of the ring 15 is formed in a protrusive mountain-like shape (inverted V-shape) toward the outside.
Sixth Embodiment
FIG. 8A and FIG. 8B each show a sixth embodiment of a pierced earring fastener. In FIG. 8A and FIG. 8B, the holder 13 is formed in a semispherical shape (whose sectional shape is formed in a semispherical shape). In addition, the ring 15 externally covers in an annular shape the full face of the semispherical face 13h of the holder 13 and the full circumference of the peripheral rim of the end face 13g. Therefore, the ring 15 fully restrains the directions in which the holder 13 is elastically deformable.
Seventh Embodiment
FIG. 9A and FIG. 9B each show a seventh embodiment of a pierced earring fastener. In FIG. 9A and FIG. 9B, the ring 15 externally covers in an annular shape a partial face of the semispherical face 13h of the holder 13 and a part of the peripheral rim of the end face 13g. In the fifth embodiment (FIG. 7A and FIG. 7B), the sixth embodiment (FIG. 8A and FIG. 8B), and the seventh embodiment (FIG. 9A and FIG. 9B), constituent elements having functions common to those of the fourth embodiment (FIG. 6A and FIG. 6B) are designated by the same reference numerals, and the descriptions are omitted.
FIG. 10A and FIG. 10B each show a first example of use of a pierced earring serving as an ornament according to the present invention. An annular hook 6 (mounting portion) for a spherically shaped ornament body 7 (auxiliary ornament member) other than the ornament portion 19a of the pierced earring 19 (main body) and a C-shaped hooking member 8 (auxiliary fixing member) other than the pierced earring fastener 1 is formed on an outer periphery face of the ring 5 (restraining member) of the pierced earring fastener 1 (fastener). This hook 6, as indicated by the virtual line of FIG. 3, is composed of a material (for example, 14KP gold) identical to that for the rings. After the pierced earring fastener 1 has been assembled, this hook 6 is fixed to the ring 5 positioned at the outermost portion by means of brazing or the like.
As shown in FIG. 10A and FIG. 10B, the pin 4 of the pierced earring 19 is inserted into a hole of an earlobe E2 at one side, and is inserted into the through hole 3a of the pierced earring fastener 1 at the other side. In this manner, the pin 4 is sandwiched between the cylinder bodies 2a′ and 2a′, and is fixed. At this time, movement of the cylinder body 2a′ is restricted by means of a restraining force of the ring 5, and an elastic reactive force of the holder 3 is enhanced. Thus, the pierced earring 19 hardly comes off. In addition, a hooking member 8 is pinched and fixed to an external ear E1 therebetween. In this way, the pierced earring 19 is securely fixed at ear E by means of the pierced earring fastener 1 and the hooking member 8, and a risk of coming-off or loss is reduced. Further, an ornament effect is increased by the presence of the ornament portion 19a (front portion of the pierced earring) and the ornament body 7 (back portion of the pierced earring) of the pierced earring 19. The ornament body 7 and the hooking member 8 may be made of metal, resin, rubber or the like.
FIG. 11A and FIG. 11B each show a modified example of a pierced earring fastener that can be used in FIG. 10 and FIG. 10B. In FIG. 11A, only a cross-shaped ornament body 7′ (auxiliary ornament member) other than the pierced earring 19 (refer to FIG. 10A) is mounted on a hook 6. In FIG. 11B, only the hook-shaped hooking member 8′ (auxiliary ornament member) other than the pierced earring 19 (refer to FIG. 10A) is mounted on the hook 6.
FIG. 12A and FIG. 12B each show a second use example of a pierced earring.
