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 motor vehicle opening element such as a motor vehicle tailgate.
  • the invention relates to a rotary lock of the type comprising a stator, in the form of a socket, and a cylindrical rotor mounted for rotation in the stator and comprising a stud eccentrically relative to the axis of rotation of the rotor and which projects axially at beyond a radial end face of the stator, for example for driving a lock mechanism.
  • a type of lock is described and represented in the 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 lock body which receives rotation a stator in the form of a socket which is angularly indexed relative to the lock body by erasable elastic means and which receives in rotation a rotor which is immobilized in rotation relative to the stator in the absence of a key, or when a false key is inserted into the lock, and which is capable of rotating a drive finger of the lock mechanism which is coaxial with the rotor and the socket when these elements rotate simultaneously, against erasable elastic means, so as not to drive the lock mechanism, and which is integral with a first lever which is articulated around a first axis integral with the sleeve and eccentric with respect to the axis of r otation of the sleeve and of the rotor and which is driven by a nipple of the rot
  • the object of the present invention is to propose an improvement to the rotary lock which makes it possible to carry out in a simple and automated manner the assembly of the various components, and in particular the assembly of the elastic means for returning the rotor to rotation relative to the stator.
  • the invention provides a rotary lock of the type mentioned above, characterized in that it comprises a double-acting spring for returning the rotor to rotation relative to the sleeve in a median angular position of rest which is arranged between a radial bottom end of the sleeve and radial end face of the rotor, in that the spring is a spiral spring, the two end branches of which are substantially parallel and each of which is capable of cooperating with one of the lateral faces for driving the stud body and with a lateral abutment surface of a stop notch formed on the bush, and in that, for the assembly of these components, the spring, carried by the end axial of the rotor and the sleeve, comprises means for the automatic engagement of the end branches of the return spring with the lateral surfaces of the stop notch, by rotation of the rotor relative to the sleeve.
  • the latch 10 consists essentially of a stator 14 in the form of a cylindrical sleeve, a rotor 12 and a return spring 16.
  • the stator 14 has an internal cylindrical wall 18 which delimits an open end 20 of the sleeve for the axial introduction of the rotor 12 and a radial bottom of the axial end 22.
  • the rotor 12 is essentially constituted by a cylindrical body 24 which is intended to be introduced axially and mounted for rotation inside the bushing forming the stator 14.
  • the body 24 of the rotor 12 has a head 26 which is in particular designed to allow the introduction of a key (not shown) which controls the movements of a set of flakes 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 XX of the rotor 12 relative to the 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 wound central body 38 and two end branches 40A, 40B which extend radially outwards and substantially parallel to one another.
  • the radial end face 34 of the rotor 12 also includes an eccentric drive stud 42.
  • the stud 42 consists essentially of a stud body 44 which is eccentrically radially outward relative to the external cylindrical surface of the body 24 of the rotor 12 and which extends axially from the radial end surface 34.
  • the body 44 thus delimits an additional thickness 46 which extends radially outward relative to the surface 24 and which is turned axially opposite the radial end face 34, while the free end of the body 44 of the drive stud comprises a drive spout 48 which is designed to cooperate with a component of a lock mechanism (not shown) in view of the latter being driven in rotation by the rotor 12.
  • the body 44 of the drive pin delimits two lateral drive faces 50A and 50B (see in particular FIGS. 6 and 7) each of which is capable of cooperating with an associated radial end branch 40A, 40B of the return spring 16.
  • the return spring 16 When it is placed in position on the core 36, as illustrated in FIG. 3, the return spring 16 is arranged so that the radial end branches 40A and 40B resiliently enclose the faces lateral drive 50A and 50B of the body 44 of the drive stud 42.
  • the rotor 12 equipped with its return spring 16 constitutes a sub-assembly, which also includes the flakes 28, which can be introduced axially into the cylindrical bore 18 of the stator 14 according to the arrow I in Figure 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 a half-circumference and is delimited at its two ends by two abutment faces 58A and 58B.
  • the 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 capable of coming alternately into contact with the end faces 58A and 58B of the light 54, with interposition of the corresponding end branch 40A, 40B of the return spring 16.
  • the lumen 54 defines an annular radial edge at the end of the cylindrical wall of the stator 14 which is divided into two parts 60A and 60B offset axially with respect to each other and separated by a stop notch 62.
  • Part 60A is thus located further from the radial end bottom 22 than part 60B.
  • the stop notch 62 projects axially from the annular end edge 60A, 60B and extends substantially in the middle position, that is to say angularly in the middle of the lumen 54.
  • the stop notch 62 extends axially to the right of the radial end bottom 22 of the stator 14.
  • the stop notch 62 delimits two lateral stop surfaces 64A and 64B, each of which, as will be explained below, is capable of cooperating with a corresponding end branch 40A, 40B of the spring 16.
  • the transverse end surface 64A is extended axially towards the free end edge 66 of the stop notch 62, by an inclined ramp 68.
  • the part 60A of the annular end edge of the sleeve 14 is designed 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, situated in the same plane as the part 60A, from the cylindrical annular wall of the sleeve 14.
  • the drive pin 42 is located angularly opposite the axial groove 52 and it is possible to introduce the rotor 12 and the spring 16 into the stator 14. This introduction continues until the position illustrated on FIG. 4 in which the radial end face 37 of the core 36 (see FIG. 3) comes into abutment against the radial end bottom 22 of the stator socket 14.
  • the drive stud 42 and the end branches 40A and 40B which project axially beyond the part 60A of the annular end edge of the stator 14, is located opposite the end face 58A of the light 54.
  • the assembly continues by causing a relative rotation of the rotor 12 relative to the stator 14 in the direction indicated by the arrow R in FIG. 4.
  • the drive pin 42 also drives the end branch 40A.
  • FIGS. 6 and 7 This assembled position is illustrated in FIGS. 6 and 7 in which the rotor 12 is in the middle rest position relative to the stator 14, this position being defined by the cooperation of the end branches 40A and 40B respectively with the lateral faces of drive 50A, 50B and the lateral abutment surfaces 64A and 64B.
  • the rotor 12 is also retained axially with respect to the stator 14 due to the cooperation of additional thickness 46 with the corresponding portions of the annular end edge of the stator socket 14.
  • the rotor 12 and the drive pin 42 alternately drives one or the other of the end branches 40A, 40B, while the non-driven branch remains in abutment against one or other of the lateral abutment surfaces 64B, 64A of the notch 62, thus causing an accumulation of force in the spring 16 which then causes the elastic return to the median position of rest illustrated in FIGS. 6 and 7.
  • the maximum angular positions of the rotor 12 relative to the stator 14 are delimited by the end faces 58A and 58B of the light 54.
  • the rotor 12 and the drive pin 42 alternately drives one or the other of the end branches 40A, 40B, while the non-driven branch remains in abutment against one or other of the lateral abutment surfaces 64B, 64A of the notch 62, thereby causing an accumulation of force in the spring 16 which then causes the elastic return to the median position of rest illustrated in FIGS. 6 and 7.
  • the maximum angular positions of the rotor 12 relative to the stator 14 are delimited by the end faces 58A and 58B of the light 54.
