Small Bijouterie and/or Jewelry Replacing Structure Which Does Not Require Outer Tool For Its Opening and Closing

Abstract

The invention relates to a bijouterie and/or jewelry assembly comprising two items removably attached to one another by an attachment device.This assembly is remarkable in that the attachment device comprises:a first attachment element (13) having a longitudinal axis (21), comprising a locking bolt (23),a second attachment element (15), comprising a locking strike (55),said first and second attachment elements being formed to prevent the relative translation thereof along said longitudinal axis and to allow the relative translation thereof along a transverse axis (29),said bolt being movable between a locked position blocking the relative translation of said first and second attachment elements along said transverse axis, and an unlocked position allowing the relative translation of said first and second attachment elements along said transverse axis.

1 . Bijouterie and/or jewelry assembly comprising:
 a first bijouterie and/or jewelry item,   a second bijouterie and/or jewelry item intended to be removably attached on said first bijouterie and/or jewelry item,   a device for attaching the first bijouterie and/or jewelry item on the second bijouterie and/or jewelry item,   said attachment device comprising:   a first attachment element mounted on said first bijouterie and/or jewelry item ( 3 ), having a longitudinal axis comprising a locking bolt,   a second attachment element mounted on said second bijouterie and/or jewelry item, configured to nest on said first attachment element and comprising a locking strike arranged to allow cooperation with said locking bolt,   said first and second attachment elements having complementary geometric shapes formed, when said second attachment element is nested on said first attachment element, to prevent the relative translation thereof along said longitudinal axis and to allow the relative translation thereof along a transverse axis that is substantially transverse to said longitudinal axis,   said locking bolt being movable alternatively between a locked position in which said locking bolt cooperates with said locking strike when said second attachment element is nested on said first attachment element, said locked position blocking the relative translation of said first and second attachment elements along said transverse axis, and an unlocked position in which said locking bolt does not cooperate with said locking strike, said unlocked position allowing the relative translation of said first and second attachment elements along said transverse axis.   wherein the locking bolt comprises a handling plate and the base of the casing of the first attachment element has a handling opening sized to allow manual access to said handling plate of the locking bolt.   
     
     
         2 . The assembly according to  claim 1 , wherein the locking bolt is mounted on an elastic return device arranged in the first attachment element to return the locking bolt to its locked position. 
     
     
         3 . The assembly according to  claim 1 , wherein the locking bolt is translatable along the longitudinal axis of the first attachment element. 
     
     
         4 . The assembly according to  claim 1 , wherein the first attachment element comprises a casing inside which the elastic return device is housed, said casing comprising:
 a base, contained in a first plane,   an apex, contained in a second plane that is axially offset relative to said base, along the transverse axis,   a set of lateral walls, connecting said base and said apex and defining an inner volume,   a locking opening formed in a lateral wall of said set of lateral walls, positioned opposite the locking strike of the second attachment element when said second attachment element is nested on said first attachment element,   said locking bolt being contained at least partially inside said inner volume and said locking opening being passed through by a locking end of said locking bolt when said locking bolt is in its locked position and when said second attachment element is nested on said first attachment element.   
     
     
         5 . The assembly according to  claim 4 , wherein the elastic return device comprises a spring comprising a first end attached to the inside of the inner volume of the casing of the first attachment element and comprising a second end attached on the locking bolt. 
     
     
         6 . The assembly according to  claim 4 , wherein the locking end of the locking bolt comprises a beveled edge. 
     
     
         7 . The assembly according to  claim 5 , wherein the locking end of the locking bolt comprises a beveled edge. 
     
     
         8 . The assembly according to  claim 1 , wherein the second attachment element is made up of a cover comprising a set of lateral walls connecting a base and an apex of said cover, the second bijouterie and/or jewelry item being mounted on one or several lateral walls of said set of lateral walls and the locking strike being formed in the lateral wall of said set of lateral walls on which said second bijouterie and/or jewelry item is mounted. 
     
     
         9 . The assembly according to to  claim 1 , wherein the first and second attachment elements each have a polygonal geometric shape. 
     
     
         10 . The assembly according to  claim 1 , wherein the first bijouterie and/or jewelry item is a ring or a necklace or an earring or bracelet and the second bijouterie and/or jewelry item is a pendant.
