Definitions

• Pivoting wrench with locking in reinforced position for actuating a lock
• the present invention relates to a key that can be used, for example, for actuating motor vehicle locks.
• keys having an integral end of a yoke mounted between two flanges of a housing for rotation about a pivot axis between a retracted position of the key in the housing and an output position of the key.
• a control pusher is mounted in the yoke to be integral in pivoting thereof and to slide between an unlocked position of the yoke in which the pusher has lugs received in notches of the housing which are positioned to correspond to each its positions, and a recessed position of release of the pivoting of the yoke in which the lugs are clear of the notches.
• a spring is interposed between the housing and the control pusher for elastically returning the yoke in its extended position and the control pusher in its locking position.
• the case is generally made of plastic while the pusher is made of metal. It is common for the housing to have, opposite the clevis, a hole for the passage of a key ring.
• An object of the invention is to provide a means of locking the yoke in position, which is more reliable while remaining simple.
• a key having an end integral with a yoke mounted in a housing for rotation between a retracted position of the key in the housing and an extended position of the key, and a pusher of control mounted in the yoke to be integral in pivoting thereof and for sliding between an output position of locking the yoke in which the pusher has at least one lug received in a notch of a housing portion and a depressed position of release of the pivoting of the yoke in which the lug escapes the notch, a spring being interposed between the housing and the control pusher to elastically return the yoke to the extended position and the control pusher to its locking position, l notch being formed in a ring reported in the housing portion and in that the ring has a hardness greater than the housing.
• Ring means any piece provided with an opening to accommodate the pusher. So, the ring is more mechanically resistant than the housing and can be made of a material as resistant as that in which the pusher is manufactured. The locking of the yoke is thus particularly strong and not subject to wear.
• the ring is inserted by force into a countersink of the first cheek.
• the housing part is overmolded on the ring.
• the housing portion comprises at least one portion that has been deformed to hold the ring in position.
• the ring comprises means for immobilizing it in rotation with respect to the first cheek, these means comprising a non-circular outer contour and advantageously at least one outwardly protruding protrusion for bearing against a surface of the housing.
• the non-circular contour may extend over all or part of the thickness of the ring.
• FIG. 1 is a perspective and exploded view of a key according to the invention
• FIG. 2 is a perspective view of a part of the key housing, this housing part being equipped with a ring according to the invention
• - Figure 3 is a partial perspective view of a first embodiment of the ring
• - Figure 4 is a partial perspective view of the housing portion equipped with a second variant of the ring.
• the key according to the invention is here described as a device for actuating locks such as those of a motor vehicle.
• the key is used for locking and unlocking the doors (doors, trunk, ...) and the steering column, as well as the actuation of the ignition switch.
• the key is mounted in a housing 2 for pivoting between a retracted position in a lateral recess 3 of the housing 2 and an extended position in which the key 1 extends 180 ° from its retracted position.
• the housing 2 is here formed of a receptacle 4 closed by a cover 5 and here encloses an electronic remote control module arranged in a manner known per se for remotely actuating a central locking and unlocking device for the openings of the motor vehicle. .
• the electronic control module can also be arranged to activate and deactivate an alarm, turn on and off the projectors of the vehicle.
• the receptacle 4 and the cover 5 are here made of a thermoplastic material, by injection.
• the cover 5 has a slot 27 having a central axis 11 which is perpendicular to the longitudinal direction of the key 1 and which coincides with the pivot axis of the key 1.
• a ring 13 is received in a countersink 14 in the cover 5 coaxially with the light 27 of the cover 5 of the housing 2.
• Notches 26 extending 180 ° from one another are formed in the thickness of the ring 13 and open on an inner circumference of the ring 13 and on the face of the ring 13 facing the receptacle 4 (the notches 26 have a height less than the thickness of the ring 13).
• the ring 13 has a non-circular outer circumference here provided with a flattened portion 15 extending in contact with a flat face of the countersink 14 to immobilize in rotation the ring 13 with respect to the cover 5.
• the ring 14 is here made of metal, and more particularly of a zinc-based alloy incorporating in particular aluminum, such as that marketed under the trademark ZAMAK.
• the ring 13 is made by decoloring, cold stamping, or stamping cut.
• the cover 5 is here overmolded on the ring 13.
• the ring 13 thus has a hardness greater than that of the thermoplastic material constituting the case 2. More generally, the ring 13 has a higher mechanical strength than that of the case 2.
• the key 1 comprises an end 6 fixed in a clevis generally designated 7 and received between two parallel flanges of the housing at one end of the lateral recess 3 for pivoting between the extended position and the retracted position of the key 1.
• the yoke 7 has two external faces 8, 9 parallel and opposite to each other.
• the yoke 7 has a bore 10 having an axis coinciding with the central axis 11 which perpendicular to the outer faces 8, 9.
• the bore 10 has a circular cross section and opens out onto the outer faces 8, 9.
• the housing 10 of the yoke 7 accommodates a hinge member generally designated 16 and a control pusher generally designated 17 between which extends a spring 18.
• the hinge element 16 has a cylindrical outer shape with a circular contour and has an end 19 received in a cavity 20 of the end of the lateral recess 3 receiving the yoke 7 and on the opposite end 21 received pivotally in the
• the end 19 of the hinge element 16 and the cavity 20 have reliefs of complementary shape immobilizing the hinge element 16 in rotation relative to the housing 2.
• the end 19 may for example comprise flats in contact with corresponding planar surfaces of the cavity 20 or an eccentric cavity receiving a corresponding relief projecting from the cavity 20.
• the end 21 has a substantially cylindrical outer shape with circular section.
• the control pusher 17 has a circular cylindrical outer surface and has an end portion 22 received in the housing 10 and an opposite end portion 23 projecting from the housing 10 and the cover 5 through the light 27. of the last.
• Two lugs 24 offset angularly relative to each other by 170 ° project from the end portion 22 and are received in grooves 12 arranged in a manner known per se in the housing 10 with a shape of bayonet to allow a sliding of the pusher between a locking position of the pivoting of the yoke 7 and a position of release of the pivoting of the yoke 7.
• the hinge member 16 and the control pusher 17 define an axis of articulation and pivoting of the yoke 7 relative to the housing 2. This hinge axis coincides with the central axis 11.
• the spring 18 has ends immobilized in rotation in the hinge member 16 and in the control pusher 17.
• the control pusher 17 here comprises a slot 27 receiving the corresponding end of the spring 18 to immobilize this end in rotation relative to the pusher.
• the spring 18 is a helical spring arranged to work in compression so that it tends to return the control pusher 17 to its locking position.
• the spring 18 when the yoke 7 is in the retracted position, the spring 18 has undergone a twist of at least 180 ° with respect to its rest state.
• the spring 18 is thus also arranged to work in torsion so that it tends to hold the pins 24 in abutment against the side of the grooves 12, and thus to bring the yoke 7 into the extended position of the key 1.
• the control pushbutton 17 in its locking position ensures both the maintenance of the yoke 7 in the output position of the key 1 as in the retracted position of the key 1. If the notches 26 are laterally delimited by flanks parallel to the direction of sliding, it is necessary to push the control button 17 in its release position to return the key 1 from its extended position to its retracted position or vice versa.
• the notches 26 of the ring 13 have a height equal to the thickness of the ring 13 so that the notches 26 open on both sides of the ring 13, facilitating the manufacture, in particular by cutting stamping.
• the ring 13 has two lateral protuberances 28 which extend outwardly from the ring 13 and which are each provided with a notch 29.
• the part of the cover 5 receiving the ring 13 has a lateral surface extending facing at least one of the protuberances laterally 28 such that this lateral protrusion 28 abuts against this surface of the lid 5 opposing a relative pivoting of the ring 13 and the lid 5.
• the notches 29 each receive a pin 30 extending projecting from the 5.
• Each peg 30 has a head which protrudes from the ring 13 and which has been deformed hot (here flattened) to press the ring 13 against the inner surface of the lid 5.
• the pins 30 can be press-fitted into holes in the ring 13.
• the ring 13 is force-fitted into the counterbore 14, the counterbore 14 having dimensions smaller than the external dimensions of the ring 13, perpendicular to the central axis 11, the ring 13 being maintained in the counterbore by elastic deformation.
• chamfers are provided on the countersink and the ring 13.
• the ring 13 has peripheral rims 31 intended to cooperate with reliefs 32 of complementary shape of the counterbore 14 to immobilize it in rotation relative to the cover 5.
