Abstract
The present invention concerns an assembly for holding or supporting a timepiece balance spring including a balance spring stud and a stud-holder, wherein said stud-holder includes: a base comprising an upper face and a lower face extending along a longitudinal axis; characterized in that the base includes a lug of non-constant shape protruding from one of the faces, said assembly further comprising a holding plate including a first opening and a second opening separated by a deformable arm, with the stud engaging in the second opening.
Claims23
An assembly for holding or supporting a timepiece balance spring, including a balance spring stud and a stud-holder, wherein the stud-holder includes:
- a base comprising an upper face and a lower face extending along a longitudinal axis;
- wherein the base comprises a lug forming a protuberance from one of said faces, said assembly further comprising a holding plate including a first opening and a second opening separated by a deformable arm, the stud engaging in the second opening, said first opening being arranged to cooperate with the lug, the cross-section of the lug having a shape such that a rotation of said holding plate causes a deformation of the deformable arm constricting the second opening and clamping the stud.
The assembly for holding or supporting a timepiece balance spring, including a balance spring stud and a stud-holder, wherein the stud-holder includes:
- a base comprising an upper face and a lower face extending along a longitudinal axis and a first opening;
- wherein the base includes a second opening separated from said first opening by a deformable arm, the stud engaging in the second opening, said assembly further including a lug arranged to cooperate with said first opening, the cross-section of the lug has a shape such that a rotation of the lug causes a deformation of the deformable arm constricting the second opening and clamping the stud.
The assembly for holding or supporting a timepiece balance spring, including a balance spring stud and a stud-holder, wherein the stud-holder includes:
- a base comprising an upper face and a lower face extending along a longitudinal axis and a hole;
- wherein the base includes a holding plate provided with a first opening and a second opening separated by a deformable arm, the stud engaging in the second opening, said assembly further including a lug arranged to cooperate with said first opening and the hole allowing the holding plate to be fixed on the base, the shape of the cross-section of said lug having such that a rotation of the lug causes a deformation of the deformable arm constricting the second opening and clamping the stud.
