Abstract

The invention relates to a tool for actuating a push-button corrector equipping a portable object of small dimensions, said actuating tool comprising a body that extends between a rear end defining an area for grasping the actuating tool and a front end defining an area for actuating the actuating tool, the actuating tool further comprising an actuating rod arranged such that it slides in a coaxial manner inside the body, the actuating rod being capable of moving from back to front and from front to back between a retracted rest position wherein it is retracted in a stable manner inside the body of the actuating tool, and a protruding working position wherein it protrudes outside of the cap, the actuating rod remaining in the protruding working position thereof as long as an axial pushing force is exerted thereon, and returns to the retracted rest position thereof as soon as the axial pushing force is released.

First claim

What is claimed is:

1. A watch and an actuating tool that actuates a push-button corrector of the watch, wherein said actuating tool comprises a body that extends between a rear end defining an area for grasping the actuating tool and a front end defining an area for actuating the push-button corrector, said body ending in a cap, wherein the actuating tool further comprises an actuating rod arranged such that it slides in a coaxial manner inside the body, the actuating rod being capable of moving from back to front and from front to back between a retracted rest position wherein it is retracted in a stable manner inside the body of the actuating tool, and a protruding working position wherein it protrudes outside of an end position of the cap, wherein the actuating rod remains in the protruding working position thereof as long as an axial pushing force is exerted thereon, and returns to the retracted rest position thereof as soon as the axial pushing force is released,
wherein the actuating tool comprises, on the side of the grasping area, a base, and on the side of the actuating area, the cap arranged in a fixed manner on the base, wherein said base and said cap form the body inside which the actuating rod is arranged such that it slides,
wherein the actuating tool comprises a helical spring threaded on the actuating rod and bearing against the cap at a front end, and against a first shoulder formed on the actuating rod at a rear end, wherein the actuating rod is capable of moving against the return force of the helical spring from back to front and from front to back between the retracted rest position thereof and the protruding working position thereof, and
wherein the actuating rod comprises, on the side of the grasping area, a first cylindrical portion with a first diameter and a second cylindrical portion with a second diameter that is less than the first diameter, and on the side of the actuating area, a third cylindrical portion with a third diameter that is less than the second diameter, wherein the cap is arranged in a fixed manner on the base and delimits, with the third cylindrical portion of the actuating rod, a third cylindrical housing inside which the helical spring is positioned in a coaxial manner, wherein the helical spring bears against the cap at a front end, and against a first shoulder formed on the actuating rod in a connection area between the second cylindrical portion and the third cylindrical portion of said actuating rod at a rear end, the third cylindrical portion projecting from the cap at the front end of the actuating tool and being surrounded by an end portion of the cap, which is also cylindrical.

2. The watch and the actuating tool according to claim 1 , wherein the cap is screwed onto the base.

3. The watch and the actuating tool according to claim 1 , wherein an end of the actuating portion of the actuating rod is coated in a layer of a material that is not as hard as the material of which the watch is made.

4. The watch and the actuating tool according to claim 1 , wherein the push-button corrector is surrounded by a circular groove machined in the watch, a diameter of an end portion of the cap corresponding to the diameter of the circular groove.

5. A tool for actuating a push-button corrector equipping a portable object of small dimensions, comprising:
a body that extends between a rear end defining an area for grasping the actuating tool and a front end defining an area for actuating the push-button corrector, said body ending in a cap, wherein the actuating tool further comprises an actuating rod arranged such that it slides in a coaxial manner inside the body, the actuating rod being capable of moving from back to front and from front to back between a retracted rest position wherein it is retracted in a stable manner inside the body of the actuating tool, and a protruding working position wherein it protrudes outside of an end position of the cap, wherein the actuating rod remains in the protruding working position thereof as long as an axial pushing force is exerted thereon, and returns to the retracted rest position thereof as soon as the axial pushing force is released,
wherein the body further comprises, on the side of the grasping area, a base, and the cap is arranged in a fixed manner on the base, wherein said base and said cap form the body inside which the actuating rod is arranged such that it slides,
wherein the actuating tool further comprises a helical spring threaded on the actuating rod and bearing against the cap at a front end, and against a first shoulder formed on the actuating rod at a rear end, wherein the actuating rod is capable of moving against the return force of the helical spring from back to front and from front to back between the retracted rest position thereof and the protruding working position thereof, and
wherein the actuating rod comprises, on the side of the grasping area, a first cylindrical portion with a first diameter and a second cylindrical portion with a second diameter that is less than the first diameter, and on the side of the actuating area, a third cylindrical portion with a third diameter that is less than the second diameter, wherein the cap is arranged in a fixed manner on the base and delimits, with the third cylindrical portion of the actuating rod, a third cylindrical housing inside which the helical spring is positioned in a coaxial manner, wherein the helical spring bears against the cap at a front end, and against a first shoulder formed on the actuating rod in a connection area between the second cylindrical portion and the third cylindrical portion of said actuating rod at a rear end, the third cylindrical portion projecting from the cap at the front end of the actuating tool and being surrounded by an end portion of the cap, which is also cylindrical.
