Abstract
A turning knob with a lock for an electric circuit indicating a body for receiving a barrel rotating relative to a stator. The barrel includes springs receiving a key configured while rotating to take up at least two functional retained or released positions and having at one of its ends a shank configured to be actuated by rotating the key. The body has an inner cylindrical sleeve whereon the stator is urged to be positioned, the inner sleeve having a number of identical members for positioning the stator, each positioning member of the inner sleeve matching a corresponding positioning member of the stator, so as to select the position of the stator relative to the body.
Claims10
1-9. (canceled)
10:
- A turning knob with a lock for an electrical circuit, comprising:
- a body configured to house a barrel turning with respect to a stator, the barrel comprising tabs, receiving a key configured to take by rotation at least two functional positions, held or fleeting, and exhibiting at one of its ends a shank actuatable by rotation of the key,
- wherein the body exhibits an internal cylindrical sleeve on which the stator positions itself,
- wherein the internal sleeve exhibits a plurality of identical positioning members for the stator, each positioning member of the internal sleeve being complementary to a corresponding positioning member of the stator, so as to be configured to choose a position of the stator with respect to the body.
11:
- The knob as claimed in claim 10, wherein the positioning members of the internal sleeve include identical notches formed on a flange of one of the ends of the internal sleeve cooperating with complementary flutes formed on an external surface of the stator.
12:
- The knob as claimed in claim 10, wherein the stator includes two diametrically opposite lateral openings, through which the tabs of the barrel are configured to project during withdrawal of the key.
13:
- The knob as claimed in claim 10, wherein the stator includes six diametrically opposite lateral openings through which the tabs of the barrel are configured to project during withdrawal of the key.
14:
- The knob as claimed in claim 10, wherein the body includes a flared part including an external collar, wherein a cup defined between the collar and the internal sleeve is configured to receive a helical spring loading a sensitivity ring that can move in translation.
15:
- The knob as claimed in claim 14, further comprising a lock-cover housed in the body and secured to the barrel, the lock-cover exhibiting teeth configured to cooperate with cam shapes formed on the sensitivity ring.
16:
- The knob as claimed in claim 14, wherein the sensitivity ring is configured to be temporarily linked to the stator by an intermeshing mechanism.
17:
- The knob as claimed in claim 16, wherein the intermeshing mechanism comprises at least two studs formed on a lateral wall of the stator, and wherein the ring is held bearing against a shoulder formed on the stator by the studs bearing on a collar formed on the ring.
18:
- The knob as claimed in claim 10, wherein the body includes a flared part furnished with an external collar, a cup defined between the collar and the internal sleeve configured to receive a torsion spring loading the barrel during its rotation.
