Definitions

  • the invention relates to a device for a latching hold (locking bracket) between two relatively rotatable parts, in particular cylindrical, mutually coaxially arranged parts of a lock, with a spring-loaded locking piece, which is mounted in the first part and in the locked position in a recess of the second part protrudes.
  • the detent (detent clamp) holding the cylinder housing to a limited extent requires a relatively high detaching torque in order to ensure reliable functioning. Since there is very little space available in such a lock, the locking clamp cannot be made so large that a sufficiently large resistance is generated in the locked state.
  • the object of the invention is to improve a device of the type mentioned in such a way that a high resistance can be generated in the locked state with small external dimensions, with a low resistance in the freewheeling state being given in the unlocked state.
  • At least one shaped piece is mounted in the locking piece which is movable and transverse to the direction of movement of the locking piece is spring-loaded, the shaped part being in contact with a laterally arranged inclined surface and / or card to generate the spring load of the locking piece.
  • Such a construction allows a high resistance with the smallest construction, i.e. a high disengagement torque in the engaged state.
  • a high disengagement torque in the engaged state i.e. a high disengagement torque in the engaged state.
  • the construction is of particularly simple construction and very safe function.
  • a spring element in particular a helical compression spring, is mounted between the two shaped pieces.
  • the shaped piece is a ball or a bolt which is rounded or beveled in particular at the front.
  • the locking piece is mounted in a recess, the side walls of which form the inclined surface (s) and / or edge (s).
  • the locking piece can also be mounted in a recess which is closed to the outside by a cover which forms the inclined surface (s) and / or edge (s).
  • the cover can be screwed into the recess and the position of the inclined surface (s) and / or edge (s) can be adjusted by its rotary adjustment.
  • the device according to the invention can be installed in a wide variety of locks and lock types. It can be used particularly advantageously in steering locks and door locks of motor vehicles.
  • the embodiment shows a motor vehicle door lock with a lock housing, which is referred to as part 1 below.
  • a radial transmission lever 2 is integrally formed on the outside of this first part 1, to which a linkage (not shown) can be articulated, which can be actuated by the door handle and / or by other drives. As a result, the first part 1 is rotated about the axis 3.
  • a cylinder housing is mounted coaxially and rotatably, which is called second part 4 below.
  • a cylinder core 5 is mounted coaxially and rotatably, in which radially displaceable tumblers are mounted, which lie in recesses in part 4 when a key that does not fit is inserted into the key channel of the cylinder core 5.
  • the cylinder core 5 and part 4 are coupled to one another in a rotationally fixed manner. If the wrong key is turned in this case, a locking clamp is overcome so that the key can be turned without being able to perform a locking function, i.e. the key is turned without performing an opening function.
  • the latching clamp has a locking piece 6 which lies with its front side 6a in a recess 7 which is arranged on the outer circumference of the part 4.
  • the front one End 6a has two inclined side surfaces, and is thus in particular conical, the recess 7 having correspondingly shaped surfaces, so that turning the part 4 above a certain torque leads to the locking piece 6 radially withdrawing outwards.
  • the locking piece 6 is radially displaceably mounted in a radial channel of part 1, the locking piece being spring-loaded in the rear region, so that the front 6a immediately engages in the recess 7 as soon as it is in the rotational position in the front and recess agree with each other in their angular rotation position.
  • a transverse bore 9 is made in the locking piece 6, in which two spherical shaped pieces 10 lie on both sides. Between the two pieces 10 there is a helical compression spring 11 which pushes the two pieces away from each other.
  • the shaped pieces 10 protrude into an enlarged space 12 which is cylindrical in the exemplary embodiment and which forms edges or inclined surfaces 13 for the shaped pieces 10.
  • the edges 13 are formed by a cover 14 which closes the space 12 from the outside and is screwed with its external thread into an internal thread of the space 12.
  • a socket-shaped, projecting region 15 of the cover 14 forms the edge 13 with its inner edge.
  • the outer end of the locking piece 6, which forms the transverse bore 9, is guided in the interior of the area 15 and does not protrude beyond the dimensions of this interior.
  • the molded pieces 10 protrude beyond the inner edge of the region 15 when the locking piece 6 is in the inner latched position.
  • the edge 13 presses the two shaped pieces 10 inward against the pressure of the spring 11, so that the shaped pieces 10 are located wholly or partly within the interior of the area 15.
  • the dimensions are chosen so that in the disengaged state the edge 13 does not reach the center of the respective fitting, so that in the disengaged state the spring 11 still exerts a radial pressure inwards over the fittings.
  • the embodiment shown is structurally particularly simple and of high functional reliability.
  • Various design alternatives are also possible, which are not shown:
  • a single shaped piece can be arranged and instead of a spherical shape, the shaped piece can also be formed by a bolt, one end of which is hemispherical.
  • a rounded or an oblique surface can be provided instead of an edge 13.
  • the shape of this rounding, or this inclined surface can be chosen so that depending on the respective radial position of the locking piece, a very specific radial pressure is exerted, which depends on the radial position of the locking piece 6.
  • the illustrated two-sided mold holder for rotary movements can be adjusted particularly easily by rotating the cover 14 into a certain radial position in which it thus has a certain desired radial distance.
