Abstract
Disclosed is a timepiece mechanism which has a mobile including a tooth of a first type and a tooth of a second type, and a pawl that is intended to move the mobile by at least one step on each actuation and has a travel that is liable to move the mobile by two steps on each actuation. This timepiece mechanism has a correction mobile designed to define different paths of the pawl, depending on the state thereof, the pawl and the correction mobile being designed such that, on each actuation of the pawl: the pawl moves the mobile by one step; and the pawl moves the mobile by an additional step only when the correction mobile is in a predefined state and the tooth of the second type is situated along the travel of the pawl.
Claims20
A timepiece mechanism for a timepiece movement, comprising:
- a toothed mobile comprising a toothset having at least one tooth of a first type and at least one tooth of a second type,
- a jumper designed to cooperate with said toothset so as to define discrete positions of said toothed mobile,
- a pawl intended to be actuated by a drive mobile of the timepiece movement in order to act on said toothset, said pawl exhibiting a travel, on each actuation, such that the pawl is able to act on said toothset in order to move said toothed mobile by two steps on each actuation,
- wherein the timepiece mechanism has a correction mobile having at least one first state and at least one second state, different from the first state, said correction mobile being designed so as to be able to cooperate with said pawl, during the actuation of said pawl, to define at least two different paths of said pawl that are associated with said first state and with said second state, respectively, and
- wherein said pawl and said correction mobile are designed such that, on each actuation of said pawl:
- said pawl acts on said toothset to move said toothed mobile by one step, and
- said pawl acts on said toothset to move said toothed mobile by an additional step only when said correction mobile is in a second state and said at least one tooth of the second type is situated along the travel of said pawl.
A timepiece movement including a timepiece mechanism comprising:
- a toothed mobile comprising a toothset having at least one tooth of a first type and at least one tooth of a second type,
- a jumper designed to cooperate with said toothset so as to define discrete positions of said toothed mobile,
- a pawl intended to be actuated by a drive mobile of the timepiece movement in order to act on said toothset, said pawl exhibiting a travel, on each actuation, such that the pawl is able to act on said toothset in order to move said toothed mobile by two steps on each actuation,
- wherein the timepiece mechanism has a correction mobile having at least one first state and at least one second state, different from the first state, said correction mobile being designed so as to be able to cooperate with said pawl, during the actuation of said pawl, to define at least two different paths of said pawl that are associated with said first state and with said second state, respectively, and
- wherein said pawl and said correction mobile are designed such that, on each actuation of said pawl:
- said pawl acts on said toothset to move said toothed mobile by one step, and
- said pawl acts on said toothset to move said toothed mobile by an additional step only when said correction mobile is in a second state and said at least one tooth of the second type is situated along the travel of said pawl.
