Jumper, timepiece movement and timepiece comprising such a jumper

An assembly comprising:

• a jumper for a timepiece movement, the jumper comprising a base attached to a frame element of said timepiece movement and from which extends an arm which can be elastically deformed, said arm bearing an abutment surface intended to cooperate with at least one notch of a mobile which can be set in motion relative to said frame element in order to temporarily immobilize said mobile in a determined position, said base comprising a support element which bears said arm, and two link elements which link said support element to a fixed element of the base, said support element, said two link elements and said fixed element forming sides of a frame, and said frame being elastically deformable so as to provoke a displacement of said support element and of said arm that it bears, such that the position of said abutment surface can be adjusted relative to said mobile;
• and
• a control member comprising:
• a body,
• a first head which can be actuated by an operator, and
• a thread arranged on an intermediate part of said body,
• said control member being arranged relative to said jumper in such a way that an action of the operator on said first head provokes a displacement of said support element.

A timepiece movement including at least one assembly, comprising:

• a jumper comprising a base attached to a frame element of said timepiece movement and from which extends an arm which can be elastically deformed, said arm bearing an abutment surface intended to cooperate with at least one notch of a mobile which can be set in motion relative to said frame element in order to temporarily immobilize said mobile in a determined position, said base comprising a support element which bears said arm, and two link elements which link said support element to a fixed element of the base, said support element, said two link elements and said fixed element forming sides of a frame, and said frame being elastically deformable so as to provoke a displacement of said support element and of said arm that it bears, such that the position of said abutment surface can be adjusted relative to said mobile;
• and
• a control member comprising:
• a body,
• a first head which can be actuated by an operator, and
• a thread arranged on an intermediate part of said body,
• said control member being arranged relative to said jumper in such a way that an action of the operator on said first head provokes a displacement of said support element, and said jumper being arranged to cooperate with a mobile of said timepiece movement.

A timepiece comprising at least one timepiece movement including at east one assembly, comprising:

• a jumper comprising a base attached to a frame element of said timepiece movement and from which extends an arm which can be elastically deformed, said arm bearing an abutment surface intended to cooperate with at least one notch of a mobile which can be set in motion relative to said frame element in order to temporarily immobilize said mobile in a determined position, wherein said base comprises a support element which bears said arm, and two link elements which link said support element to a fixed element of the base, wherein said support element, said two link elements and said fixed element form sides of a frame, and wherein said frame can be elastically deformed so as to provoke a displacement of said support element and of said arm that it bears, such that the position of said abutment surface can be adjusted relative to said mobile;
• and
• a control member comprising:
• a body,
• a first head which can be actuated by an operator, and
• a thread arranged on an intermediate part of said body,
• said control member being arranged relative to said jumper in such a way that an action of the operator on said first head provokes a displacement of said support element, and said jumper being arranged to cooperate with a mobile of said timepiece movement.
