Definitions
- the present invention relates to a rotary lock.
- the invention relates in particular to a rotary lock for driving a lock mechanism fitted to a opening of a motor vehicle such as a vehicle tailgate automobile.
- the invention relates to a rotary lock of the type comprising a stator, in the form of a socket, and a rotor cylindrical mounted for rotation in the stator and comprising an eccentric pin relative to the axis of rotation of the rotor and which projects axially beyond a radial face end of the stator, for example for training a lock mechanism.
- a type of lock is described and represented in document FR-A-2,642,463 which describes and represents a disengageable mechanism for controlling a lock of the type comprising a lock which comprises a body bolt which receives in rotation a stator in the form of socket which is angularly indexed relative to the body bolt by elastic erasable means which rotatably receives a rotor which is immobilized in rotation relative to the stator in the absence of a key, or when a wrong key is inserted into the lock, and that is likely to cause a finger to rotate of the lock mechanism which is coaxial with rotor and socket when these elements rotate simultaneously, against erasable elastic means, so as not to entrain the mechanism of lock, and which is integral with a first lever which is articulated around a first axis integral with the socket and offset from the axis of rotation of the sleeve and the rotor and which is driven by a pin of the rotor eccentric with respect to the latter's axis of rotation
- the object of the present invention is to provide a improvement to the rotary lock which enables simple and automated assembly of different components, including the assembly of elastic means for returning the rotor to rotation by report to the stator.
- the invention provides a rotary lock of the type mentioned above, characterized in that it includes a double-acting return spring of the rotor relative to the bush in a position angular median of rest which is arranged between a bottom radial end of sleeve and end face radial of the rotor, in that the spring is a spring hairspring with two end branches substantially parallel and each of which is likely to cooperate with one of the lateral drive faces of the nipple body and with a lateral abutment surface of a stop notch formed on the sleeve, and in that, in view of the assembly of these components, the spring, carried by the axial end of the rotor and the sleeve has means for automatic engagement of branches ends of the return spring with the surfaces lateral of the thrust notch, by rotation of the rotor by compared to the socket.
- the lock 10 consists essentially of by a stator 14 in the form of a cylindrical socket, a rotor 12 and a return spring 16.
- the stator 14 has a cylindrical wall internal 18 which delimits an open end 20 of the bush for axial insertion of rotor 12 and bottom axial end radial 22.
- the rotor 12 is essentially constituted by a cylindrical body 24 which is intended to be introduced axially and rotatably mounted inside the sleeve forming stator 14.
- the body 24 of the rotor 12 has a head 26 which is in particular intended to allow the introduction of a key (not shown) which controls the movements of a set of sequins 28 which are received in slots 30 formed in the rotor 12 and in slots 32 formed in the annular cylindrical wall of the stator 14.
- the radial end face 34 of the rotor 12 which is intended to be received inside the stator 14 comprises a central extension in the form of a cylindrical core 36 which is concentric with the axis of rotation X-X of the rotor 12 relative to stator 14.
- This core is designed to receive the body 38 of the return spring 16 which is a spring of the spiral type.
- the spring 16 thus comprises a central body coiled 38 and two end branches 40A, 40B which extend radially outward and substantially parallel to each other.
- the radial end face 34 of the rotor 12 also includes an eccentric drive stud 42.
- the nipple 42 consists essentially of a body of nipple 44 which is offset radially outwards by relative to the external cylindrical surface of the body 24 of the rotor 12 and which extends axially from the surface radial end 34.
- the body 44 thus defines an extra thickness 46 which extends radially outward from the surface 24 and which is rotated axially opposite the radial end face 34, while the free end of the body 44 of the drive stud has a spout 48 which is intended to cooperate with a component of a lock mechanism (not shown) in view of the rotational drive of the latter by the rotor 12.
- the body 44 of the drive stud delimits two lateral drive sides 50A and 50B (see in particular Figures 6 and 7) each of which is likely to cooperate with an associated radial end branch 40A, 40B of the return spring 16.
- the spring of reminder 16 When it is placed in position on the core 36, as illustrated in figure 3, the spring of reminder 16 is arranged so that the radial branches end 40A and 40B resiliently enclose the faces lateral drive 50A and 50B of the body 44 of the stud training 42.
- the rotor 12 fitted with its return spring 16 constitutes a sub-assembly, which also includes the sequins 28, which can be inserted axially into the cylindrical bore 18 of stator 14 according to arrow I in FIG. 3.
- the bore 18 has an axial groove 52 which opens in the open end 20 of the bore 18 and which opens into the radial end bottom 22.
- the axial groove 52 opens into an annular opening 54 which is formed in the cylindrical wall 56 of the socket 14.
- the annular lumen 54 extends substantially over half a circumference and is delimited at its two ends by two abutment faces 58A and 58B.
- end faces 58A and 58B thus delimit the angular travel of the rotor 12 relative to the stator 14, the lateral drive faces 50A and 50B being likely to come in contact with end faces 58A and 58B of light 54, with interposition of the corresponding end branch 40A, 40B of the return spring 16.
- the lumen 54 defines an annular radial end edge of the cylindrical wall of the stator 14 which is divided into two parts 60A and 60B offset axially, one by relative to each other and separated by a stop notch 62.
- Part 60A is thus located further from the bottom radial end 22 as part 60B.
- the stop notch 62 projects axially from the annular end edge 60A, 60B and extends substantially in the middle position, i.e. angularly in the middle of the light 54.
- the stop notch 62 extends axially up to right from the radial end bottom 22 of the stator 14.
- the stop notch 62 delimits two lateral surfaces 64A and 64B each of which, as will be explained later, is likely to cooperate with a corresponding end branch 40A, 40B of the spring 16.
- the transverse end surface 64A is extends axially towards the free end edge 66 of the stop notch 62, by an inclined ramp 68.
- Part 60A of the annular end edge of the socket 14 is provided to cooperate with the additional thickness 46, over a portion of the angular travel of the rotor 12, the latter also cooperating with a portion 70, located in the same plane as part 60A, of the wall cylindrical annular sleeve 14.
- the nipple 42 also drives the industry end 40A.
- the rotor 12 is also retained axially by report to stator 14 due to the cooperation of extra thickness 46 with the corresponding portions of the edge annular end of the stator socket 14.
- the maximum angular positions of the rotor 12 by relative to stator 14 are delimited by the faces end 58A and 58B of the light 54.
