Problems solved by technology

[0020] In short, known implementations are often complex and difficult to adapt to different escapements
The method of stopping the balance wheel is often abrupt, and it is not always guaranteed that the movement of the balance wheel can be restarted without intervention

Embodiment Construction

[0035] The invention relates to the field of horology.

[0036] The invention relates to an anti-trip device 1 for an escapement 10, arranged to cooperate with a balance wheel 2 pivoting about a first pivot axis D1, the position of which is relative to Splint 3 is fixed.

[0037] According to the invention, the anti-tripping device 1 comprises a pivot wheel set 5 pivotable about a second pivot axis D2 parallel to said first pivot axis D1 and The position of the second pivot axis D2 is fixed relative to the bridge.

[0038] Pivoting wheel set 5 comprises guide means 7 arranged to cooperate with complementary guide means 9 contained in disc 3 arranged to be fixed to balance wheel 2 so as to pivot integrally with balance wheel 2 .

[0039] In another embodiment, the guiding means 7 or the complementary guiding means 9 comprise an eccentric 90 arranged so that when the balance is pivoted in the first pivoting direction B1, the eccentric 90 causes the pivoting wheel set 5 to Mo...

Abstract

The invention concerns an anti-trip device (1) for an escape mechanism (10) arranged to cooperate with a balance (2) pivoting about a first axis (D1). The anti-trip device (1) includes a pivoting wheel set (5), pivotally moveable about a second axis (D2) parallel to said first axis (D1) and fixed relative to a plate. The pivoting wheel set (5) includes guide means (7) arranged to cooperate with complementary guide means (9) comprised in a roller (3) pivoting integrally with said balance (2). Said complementary guide means (9) includes a cam (90) for moving said pivoting wheel set (5) closer to said first axis (D1) when said balance is pivoting in a first direction (B1) and to move said wheel set away from said first arbour when the balance is pivoting in a second direction (B2) opposite to said first direction (B1). Said guide means (7) includes a fixed finger arranged to cooperate with said cam.

Description

technical field [0001] The invention relates to an anti-trip / anti-trip device for an escapement arranged to cooperate with a balance wheel pivoting about a first pivot axis, the first pivot The position of the axis of rotation is fixed relative to the splint. [0002] The invention also relates to an escapement comprising at least one balance wheel pivotable relative to a bridge and about a balance axis. [0003] The invention also relates to a timepiece movement comprising at least one escapement of the type described above. [0004] The invention also relates to a timepiece comprising at least one timepiece movement of the above-mentioned type and / or at least one escapement of the above-mentioned type. [0005] The present invention relates to the field of horology, in particular escapements, and more particularly in the field of detent escapements. Background technique [0006] The detent escapement has a reputation for being the most accurate and has long been used in...
