Mechanism for locking pin for personal ornaments

Abstract

The invention relates to a mechanism for locking a pin for a personal ornament, wherein is capable of safely and reliably locking an ornament to a target such as clothing fabric. A mechanism for locking a pin for a personal ornament is characterized by including a personal ornament main body including a single pin member having a proximal portion extending rearward from the back surface of a base member of a personal ornament main body and a distal portion bent from the proximal portion and extending along the back surface of the base member, a groove opening to the surface for allowing the proximal portion of the pin member to pass therethrough, and a retaining member formed in the direction intersecting with respect to the groove for tightly accommodating the distal portion of the pin member without clearance.

1 . A mechanism for locking a pin for a personal ornament comprising: 
 a personal ornament main body including a single resilient hook-shaped pin member having a proximal side extending vertically with respect to the surface of the base member and a distal side extending substantially parallel to the surface of the base member, the pin member being secured to the back surface of the base member; and    a retaining member including a pin member storage having a groove communicating with the opening on the surface opposing to the base member for fitting the proximal portion of the pin member, the pin member storage being formed so as to extend in one direction from the inner most portion of the groove continuously therefrom, the pin member storage being capable of tightly accommodating the distal portion of the pin member, and the retaining member having a surface inclined so as to vary the thickness thereof in the direction of extension of the groove.    
   
   
       2 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the retaining member comprises a groove opening to the surface of the retaining member opposing to the personal ornament main body for retaining the proximal portion of the pin member and a pin member storage formed in the direction intersecting with respect to the groove.  
   
   
       3 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the groove includes a groove portion opening to the surface of the retaining member and being capable of allowing the distal portion of the pin member to be fitted so as to move in the fore-and-aft direction, and wherein the pin member storage is formed continuously from the inner most portion of the groove in one direction so as to be capable of tightly accommodating the distal portion of the pin member.  
   
   
       4 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the pin member is formed of resilient material.  
   
   
       5 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein an antiskid member is provided on the surface of the retaining member.  
   
   
       6 . A mechanism for locking a pin for a personal ornament according to  claim 5 , wherein the antiskid member is a serrated projection in cross-section.  
   
   
       7 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the surface of the retaining member is inclined so as to gradually increase the thickness of the retaining member in the direction of extension of the groove.  
   
   
       8 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the distal portion of the pin member extends upwardly with respect to the personal ornament main body.  
   
   
       9 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the pin member storage is disposed so that the distal portion of the pin member is bent against the resilient force thereof when storing the distal portion of the pin member, and the personal ornament main body is urged by the resiliently restoring force of the pin member toward the retaining member.  
   
   
       10 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the personal ornament main body is any one of a badge, a broach, a tiepin, a cuff button, and a piercing jewelry.  
   
   
       11 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein a bent portion between the proximal portion and the distal portion of the pin member is curved.  
   
   
       12 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the pin member is attached to a personal ornament main body so that the distal portion is capable of rotating about the proximal portion.  
   
   
       13 . A mechanism for locking a pin for a personal ornament according to  claim 1 , wherein the surface of the retaining member is inclined so as to reduce the thickness of the retaining member gradually in the direction of extension of the groove.  
   
   
       14 . A mechanism for locking a pin for a personal ornament comprising: 
 a personal ornament main body including a single hook-shaped pin member formed of resilient material and secured to the back surface of a base member, the pin member having a proximal side extending vertically with respect to the surface of the base member and a distal side extending substantially in parallel with the surface of the base member; and    a retaining member comprising a pin member storage opening to a bottom surface of the retaining member and extending in one direction so as to be capable of tightly accommodating the distal portion of the pin member, the retaining member having a surface inclined in such a manner that the thickness varies in the direction of extension of the groove.
