Device and method for the pivoting assembly of at least two components and corresponding assembly made of two assembled components
The assembly device is intended for the pivoting attachment of at least two components (M 1 , M 2 ). It comprises a screw ( 4 ) intended to be screwed into a first component (M 1 ) and bearing a guide pin ( 5 ) guiding the pivoting of a second component (M 2 ). According to the invention, the pin ( 5 ) comprises at least one rotation-prevention zone ( 540 ) having a shape designed to collaborate with a zone of corresponding shape of the first component (M 1 ), so as to prevent said pin from rotating.
1. A bracelet comprising at least a first link and a second link, and an assembly device pivotably attaching the first and second links, comprising:
a screw configured to be screwed into the first link, and
a pin borne by the screw and configured to guide a pivoting of the second link, wherein the pin comprises at least one rotation-prevention zone having a shape configured to collaborate with a zone of corresponding shape of the first link, so as to prevent the pin from rotating.
2. The bracelet as claimed in claim 1 , wherein the screw is housed in the pin and wherein the pin and the screw are designed to collaborate so that the screw drives the pin in an axial translation when the pin is prevented from rotating and the screw is being screwed into the first link.
3. The bracelet as claimed in claim 2 , wherein the screw is equipped with a head arranged at an open first end of the pin and an end part bearing a screw thread and extending out of the pin at an open second end of said pin.
4. The bracelet as claimed in claim 3 , wherein the rotation-prevention zone is a peripheral rotation-prevention zone arranged near the first end of the pin.
5. The bracelet as claimed in claim 1 , wherein the rotation-prevention zone is a peripheral rotation-prevention zone and wherein a shape of the rotation-prevention zone is at least one selected from the group consisting of a projecting shape, a reentrant shape and a flat.
6. The bracelet as claimed in claim 1 , comprising radial retention means between the pin and the screw for allowing a relative angular movement between the pin and the screw.
7. The bracelet as claimed in claim 1 , further comprising at least one seal positioned between the screw and the pin, designed to exert a retention torque between the screw and the pin providing a retention between the pin and the screw.
8. The bracelet as claimed in claim 7 , wherein the retention between the pin and the screw is a radial retention.
9. The bracelet as claimed in claim 1 , wherein the pin is secured to the screw in terms of an axial translation through a collaboration of at least one stop of an internal portion of the pin with at least one stop surface borne by the screw.
10. The bracelet as claimed in claim 1 , wherein the pin and the screw bear respective toothsets designed to collaborate by a claw coupling, under an effect of elastic return means, so as to exert a retention torque providing retention between the pin and the screw.
11. The bracelet as claimed in claim 10 , wherein the elastic return means comprise a helical spring housed inside the pin and surrounding the screw, the spring pressing against a bearing surface borne by the screw, at one end, and against a bearing surface borne by the pin, at another end.
12. The bracelet as claimed in claim 11 , wherein the spring is preloaded by assembling an end part of the screw, bearing a screw thread, and a head part and intermediate part of the screw which are joined to one another.
13. The bracelet as claimed in claim 10 , wherein the retention between the pin and the screw is a radial retention.
14. The bracelet as claimed in claim 1 , wherein the screw is fixed into the first link of the bracelet and wherein the pin forms a pivoting surface for the second link of the bracelet.
15. The bracelet as claimed in claim 14 , wherein the screwing of the screw induces an axial translation of the pin relative to the first link of the bracelet.
16. A method of pivotably assembling the first and second links of the bracelet as claimed in claim 1 , wherein the method comprises:
introducing the assembly device into an opening passing through the second link,
screwing during which the screw is screwed into the first link and drives in an axial translation of the pin of the device, which is prevented from rotating through the collaboration of the rotation-prevention zone with the zone of corresponding shape of the first link.
17. An assembly device for pivotably attaching at least two components, comprising:
a screw configured to be screwed into a first component, and
a pin borne by the screw and configured to guide a pivoting of a second component, wherein the pin comprises at least one rotation-prevention zone having a shape configured to collaborate with a zone of corresponding shape of the first component, so as to prevent the pin from rotating,
wherein the pin is secured to the screw in terms of axial translation through a collaboration of at least one stop of an internal portion of the pin with at least one stop surface borne by the screw.
18. An assembly device for pivotably attaching at least two components, comprising:
a screw configured to be screwed into a first component, and
a pin borne by the screw and configured to guide a pivoting of a second component, wherein the pin comprises at least one rotation-prevention zone having a shape configured to collaborate with a zone of corresponding shape of the first component, so as to prevent the pin from rotating,
wherein the screw is equipped with a head arranged at an open first end of the pin and an end part bearing a screw thread and extending out of the pin at an open second end of said pin.
