摘要： A self-locking expansion device which connects a watchcase ( 1 ) to two ends of a strap or bracelet ( 2 ), comprises a first and a second deployable elements ( 3, 4 ), each having one end pivotally connected, or arranged to be pivotally connected, to an end of the strap or the bracelet ( 2 ), and another end pivotally connected directly or indirectly to the watchcase ( 1 ) between a locked position and an unlocked position. Said deployable elements ( 3, 4 ) are so shaped that in the locked position they are confined under the back of the watchcase ( 1 ), or lie either against the circumference of the watchcase ( 1 ), or over the front of the watchcase ( 1 ). The deployable elements ( 3, 4 ) are movable between the locked and the unlocked position by turning the watchcase ( 1 ) while the ends of the strap or bracelet ( 2 ) move together or apart.

摘要： PROBLEM TO BE SOLVED: To provide a device which can change the profile of a necklace in response to preference by making two sections of a chain approach each other, or changing the length of the chain when the device is attached to the string of the necklace. SOLUTION: The openings of half shell bodies 2 and 3 are superposed on the openings of the other half shell bodies, and the half shell bodies are attached to each other in a manner to allow the chain to pass a space between them. In the two shell bodies, an elastic element such as a spring 7, which is attached under a compressed state, exists. Then, the spring 7 pushes the two half shell bodies to the outside, and arranges the half shell bodies at locations with a distance. By the sliding or the arrangement being apart from each other of the two half shell bodies, the openings lose the aligned state in the axial direction. As a result, the section of the chain being engaged with the opening is gripped and deformed, and a frictional force is generated. Then, a button is fixed to the same chain by the frictional force.

摘要： PURPOSE: To provide a clasp used for a bracelet that does not change the thickness of the bracelet even while the clasp is inserted into the bracelet ring and it can greatly prolong the length of the bracelet at the opening and shorten its rigid part at the fastening. CONSTITUTION: The clasp 1 is nested and extensional. A first pipe 2 designed for this clasp is covered on the front and side faces by a number of rinks 5, and these rinks 5 are the same as the other rinks used in the bracelet. A second pipe 8 can be inserted into the first pipe 2, the second pipe 8 can recover a plate type third element 10 and a block device is installed in the third element 10 so as to keep the clasp at the drew position. While using this clasp in a bracelet, the bracelet has the same thickness as the rinks 5 that form the bracelet.
