Definitions

  • a pin holder type fastener in a bodily ornament such as, for example, a pierced earring, as shown in (a) in Fig. 1 , has a structure in which a pin 1 having a peripheral groove 2 in a vicinity of a leading extreme portion is inserted into a pin fastener (omitted from the figure), and a holding member 3 of the pin fastener is moved into a position in which it locks into the peripheral groove 2, and is fixed. Then, as shown in (b) in Fig. 1 , by causing the holding member 3 to withdraw from the peripheral groove 2 by means of an appropriate operation, it is possible to extract the pin 1 from the pin fastener.
  • a pin fastener shown by sectional views in (a) and (b) in Fig. 3 is also proposed.
  • a pair of holding members 16 made of a material capable of an elastic deformation are housed inside a cover 15, which overall is circular or elliptical.
  • each of the holding arms 19 of the two holding members 16 pushes the other holding member 16 in an opposite direction, as a result of which, the pair of pin holder arms 18 is pushed in a direction of the pin insertion portion 17. For this reason, a pin (omitted from the figure) which is in the pin insertion portion 17 is held by the pair of pin holder arms 18.
  • both extremes of the pair of inclining portions of the pin holder are pinched between a thumb and an index finger, and a force is applied in such a way as to reduce a space between the extremes of the inclining portions (to cause an elastic compression deformation of the triangular side view shape of the pin holder).
  • a force is applied in such a way as to reduce a space between the extremes of the inclining portions (to cause an elastic compression deformation of the triangular side view shape of the pin holder).
  • a third aspect of the invention is a fastener wherein, in the case of providing the bottom edge portion in both of the longitudinal direction extreme portions of the inclining portions, by means of ear tabs provided on one of the bottom edge portions and bend formed in a direction of the other bottom edge portion, the two bottom edge portions are mutually restricted in a condition in which a relative sliding movement in the longitudinal direction is possible.
  • a fourth aspect of the invention is a fastener including: a pin holder; and a pin in which is provided a holding portion formed by a peripheral groove, a depressed portion or a protruding portion in a leading extreme portion vicinity, the fastener holding the pin by locking a holding member of the pin holder onto the holding portion of the pin, and ending a pinning condition by causing the holding member to withdraw from the holding portion, wherein the pin holder, by bend forming a central portion of a longitudinal direction of a thin plate-like spring material into an acute angle or an arc, is formed to have a triangular side view shape formed by an apex and a pair of inclining portions on either side thereof, and as well as providing a pin holder hole for inserting the pin in the apex, turnback tabs protrude in a non-longitudinal direction one from each of the pair of inclining portions, and are bend formed in such a way as to overlap on a front surface of the inclining portions

  • the turnback tabs bend formed in such a way as to overlap on a front surface of the inclining portions include the holding members, every time an operation of inserting the pin in the pin holder is carried out, a force is received which attempts to lift the turnback tabs up from the front surface of the inclining portions. Then, in the event that the turnback tabs are lifted up from the front surface of the inclining portions, it becomes impossible to realize a good pinning condition. Consequently, by using the ear tabs to bring the turnback tabs into close contact with the inclining portions, as in the seventh aspect, it is possible to completely prevent this kind of defect.
  • An eighth aspect of the invention is the fastener in the heretofore described sixth aspect or seventh aspect wherein, in the case of providing the bottom edge portion in both of the longitudinal direction extreme portions of the inclining portions, by means of ear tabs provided on one of the bottom edge portions and bend formed in a direction of the other bottom edge portion, the two bottom edge portions are mutually restricted in a condition in which a relative sliding movement in the longitudinal direction is possible.

  • the structure of the pin holder is slightly complex in comparison with the case of the first aspect, as it is not necessary to form the pin holder hole and the holding member in the same portion of the thin plate-like spring material, a process of forming the pin holder hole and the holding member is easy.
  • An eleventh aspect of the invention is the fastener in the heretofore described tenth aspect wherein, in the case of bend forming the pin holder tabs in such a way as to overlap on the front surface of the inclining portions, by means of ear tabs provided in a non-longitudinal direction of the pin holder tabs, and bend formed in a direction of the inclining portions, the pin holder tabs are brought into close contact with the inclining portions.
  • the pin holder tabs bend formed in such a way as to overlap on a front surface of the inclining portions include the holding members, every time an operation of inserting the pin in the pin holder is carried out, a force is received which attempts to lift the pin holder tabs up from the front surface of the inclining portions. Then, in the event that the pin holder tabs are lifted up from the front surface of the inclining portions, it becomes impossible to realize a good pinning condition. Consequently, by using the ear tabs to bring the pin holder tabs into close contact with the inclining portions, as in the eleventh aspect, it is possible to completely prevent this kind of defect.

  • the ornament fastener according to the twelfth aspect, it is not necessary to integrally form the spring member configuring the pin holder and the holder base including the holding members. Also, it being sufficient that a material configuring the spring member is a material which can be elastically deformed, it is not necessary to use a material with which a bending process is possible. Due to these points, a selection of the material and a design of the fastener are relatively easy. Also, as the structure of the pin holder is simple, it is possible to provide a low cost fastener.
  • the pin When pinning the fastener, the pin is inserted into the pin holder hole of the apex from a bottom edge side of the triangular shape of the pin holder. At this time, the pin exerts a force on the holding members protruding into the pin holder hole which attempts to push the holding members out. This force is transmitted to the spring material via the holder base including the holding members and, by the spring member bringing about a certain degree of deformation, the pin pushes out the holding members, and is inserted into the pin holder hole.

  • the apex 30 bend formed into an arc has a shape wherein the pair of holding members 27 protrude from the peripheral portion of the longitudinal direction in the pin holder hole. As the pair of holding members 27 are not bend processed, they protrude in the same direction as the inclining portions. When the pin 23 is inserted into the pin holder hole, the pair of holding members 27 protrude to a length such as to bite into a peripheral groove 23a of the pin.

That is, when pinning the fastener 21, the pin 23 is inserted from a bottom edge of the triangular shape of the pin holder 22 into the pin holder hole of the apex 30. At this time, the pin 23 is inserted while elastically deforming the pair of holding members 27 protruding into the pin holder hole, and pushing them out to an exterior. As the pair of holding members 27 protrude in the same direction as the inclining portions 31, they do not exhibit a strong resistance to the heretofore described insertion of the pin. Then, on the peripheral groove 23a of the pin 23 reaching a protrusion position of the holding members 27, the holding members 27 elastically return to an original shape and move into the peripheral groove 23a of the pin 23, and the pinning is completed.

  • extension portions 35 for configuring bottom edge portions 37 are provided at either extreme of a longitudinal direction.
  • pin through holes 36 are formed in portions which come immediately below the apex 30 when configuring the bottom edge portions 37. As the pin through holes 36 are formed in long ovals in a left-right direction of the figure, the inserted pin 23 can move relatively in the left-right direction.
  • each leading extreme of the pair of bottom edge portions 37 is of a length such that it does not reach a base of the other bottom edge portion 37. Consequently, as shown in (a) of Fig. 6 , when ending a pinning condition of the fastener 32, they do not constitute an obstacle to an operation causing an elastic deformation of the apex 30 of the pin holder 33 in such a way that it bends more acutely.
  • ear tabs 38 are formed at a leading extreme of one of the extension portions 35. After forming the bottom edge portions 37 in the way heretofore described, the ear tabs 38 are bend formed in a direction of the other bottom edge portion 37. Although the same also applies to ear tabs shown in each of the following examples, it is also acceptable, in order to facilitate a bending back along depicted broken lines, to put a shallow, groove-shaped notch in the ear tabs 38. By means of the bending formation of the ear tabs 38, the two bottom edge portions 37 restrain each other in a condition in which a relative sliding movement is possible in a longitudinal direction.
  • the pair of holding members 27 in this Example 2 are of a shape wherein they have the same width from a base to a tip, it is particularly preferable that they are of a shape wherein the width gradually becomes less heading toward the tip, as shown in (b) of Fig. 5 .
  • a portion corresponding to the apex 30 in the template member 34 is of a greater width than base portions of the holding members 27 in the template member 34 (portions indicated by widths B) .
  • a bending force does not concentrate in the portion indicated by the width A. Consequently, as shown in (b) of Fig. 8 , it is possible to bend a whole, from the portion indicated by the width A as far as the portions indicated by the widths B on either side thereof, evenly in a gentle arc.
  • the apex 30 having this kind of bending shape exhibits a superior durability in response to a repetition of a pinning condition ending operation which causes an elastic compression deformation of a triangular side view shape of the pin holder 33.
  • the pair of holding members 27 are of the shape wherein they have the same width from the base to the tip, the bending force in the bend processing of the template member 34 concentrates in the portion corresponding to the apex 30, and this portion is bent into a sharp arc.
  • a distance W between the tips of the pair of holding members 27 is small in comparison with the case of (b) of Fig. 8 , to be described hereafter. That is, in order to withdraw the pair of holding members 27 from the peripheral groove of the pin 23, it is necessary to cause a greater compression deformation of the pin holder 33. A repetition of a large compression deformation has an adverse effect on a durability of the elastic deformation capacity of the apex 30.
  • a using condition of the fastener 32 according to Example 2 is the same as in the case of Example 1, with the exception of points described next. That is, in the pinning of the fastener 32, the pin 23 is passed from a bottom edge side of the triangular shape of the pin holder 33, through the pin through holes 36, then inserted into the pin holder hole of the apex 30. Movements of the pin 23 and the pin holder 33, which are in the pinning condition, are mutually restricted at two points, the pin holder hole of the apex 30 and the pin through holes 36 of the bottom edge portions 37. For this reason, as the pin holder 33 does not wobble around the pin 23, an ornament in the pinning condition does not wobble unsteadily.
  • the pin holder 33 has a high structural strength.
