  • These relative movements are possible, for example, in the lateral direction of the inlet slot, into which the closing element is immersed during a closing process, due to the play between the closing element and the rotary latch, and generate undesirable noises.
  • the relative movements lead to unnecessary friction between the closing element and the rotary latch, which has a detrimental effect on the wear and tear and the service life of the components involved in the relative movements.
  • the invention is based on the object of creating a solution which provides an improved lock arrangement in a structurally simple manner, by means of which the aforementioned disadvantages are avoided and in which the lateral play between the locking element and the rotary latch is reduced to a minimum.

  • the functional surfaces 30a, 30b are arranged pivoted with respect to the inlet position, as shown in FIG Figure 37 can be seen.
  • the functional surfaces 30a and 30b form the intermediate space 16 between them, but this is the case in comparison for the inlet position is designed with a maximum clamping width 19, which is smaller than the maximum inlet width 17 (see Figure 37 ).
  • the dimensioning of the maximum clamping width 19 is based on the cross-section or diameter of the closing element 5 and corresponds at most to the cross-section of the bow-shaped and circular in cross-section closing element 5, because in the clamping position the functional surfaces 30a and 30b of the clamping device 11 clamp the closing element 5 at least in sections between them and block a lateral movement of the closing element 5 in the direction of the side edges of the inlet slot 10.
  • a respective functional surface 30a, 30b has the guide-retaining section 21 and a rounded section 33.
  • the respective guide-retaining sections 21 are inclined in a direction pointing out of the inlet slot 10 and are arranged to run towards one another (see, for example, FIG Figure 36 ), so that the retaining sections 21 close off the intermediate space 16 at their end pointing away from the rotary latch 6 and thus block a movement of the closing element 5 located in the intermediate space 16 out of the intermediate space 16 in a direction pointing away from the rotary latch 6.
  • the respective rounded sections 33 form a circular segment-shaped clamping section 34, in which the closing element 5 is arranged at least in sections so as to be clamped (see for example Figures 37 , 48 and 49 ).
  • the clamping bracket 32a is designed identical and mirror-symmetrical to the clamping bracket 32a and has a receiving chamber 35 for the movable mounting of the clamping element 31a or 31b as well as the insertion slot 25a for fastening the Clamp bracket 32a on the lock housing 4.
  • the clamping device 11 of the second embodiment is formed from a pair of clamping elements 31a, 31b and clamping brackets 32a, 32b, wherein the clamping brackets 32a, 32b can be designed mirror-symmetrically to one another, whereas the two clamping elements 31a and 31b are designed asymmetrically to one another, as will be explained below .
  • a pivot arm 36a or 36b and a pivot recess 37a or 37b are formed, such as the Figures 32 and 33 can be found.
  • the pivot arm 36a of the clamping element 31a extends in the direction of the clamping element 31b
  • the pivot arm 36b of the clamping element 31b extends in the direction of the clamping element 31a.
  • a respective pivot arm 36a, 36b of the one clamping element 31a, 31b extends in the direction of the other clamping element 31b, 31a.
  • the two clamping elements 31a and 31b are designed asymmetrically to one another.
  • the pivot arms 36a and 36b are offset from one another and arranged on the respective clamping element 31a, 31b that a movement of the clamping elements 31a, 31b is allowed, in which the pivot arms 36a and 36b can move past one another.
  • the swivel arms 36a, 36b are arranged in such a way that they cross one another (see for example Figures 36 and 38 ), whereas in the clamping position of the clamping device 11 the pivot arms 36a, 36b are arranged so as to overlap at least in sections (see for example Figures 37 and 44 ).
  • the respective pivot recesses 37a and 37b allow this movement of the pivot arms 36a and 36b.
  • the pivot arm 36a of the clamping element 31a is designed to move through the pivoting recess 37b of the other clamping element 31b when the clamping device 11 is moved from the inlet position into the clamping position.
  • Swivel arm 36b of the clamping element 31b is designed to move through the swiveling recess 37a of the other clamping element 31a when the clamping device 11 is moved from the inlet position into the clamping position.
  • the pivot arms 36a and 36b serve to pivot the clamping elements 31a and 31b essentially synchronously when the closing element 5 moves in the direction of the rotary latch 6 and dips into the inlet slot 10 with a transverse offset in relation to the latter.
  • an actuation space 38a or 38b is formed between a free end of a pivot arm 36a or 36b and the functional surface 30b or 30a of the other pivot arm 36b or 36a which has a width 39 which is smaller than a maximum cross-sectional width 40 of the closing element 5. This relationship is shown in FIG Figure 39 shown for the actuation space 38b.
  • FIG. 38 and 39 a position of the closing element 5 at the beginning of the closing process is shown, in which the clamping device 11 is arranged in its inlet position and the clamping elements 31a and 31b on the respective first movement limiting surface 23 of the associated Clamp brackets 32a, 32b are in contact.
  • the functional surfaces 30a and 30b are inclined and converge in the direction of the rotary latch 6 and are arranged in a funnel shape, so that the functional surfaces 30a and 30b guide the closing element 5 in the direction of the rotary latch 6.
  • a lateral offset of the closing element 5 in the direction of the clamping element 31a or the clamping element 31b is compensated by the clamping device 11, wherein in the Figures 38 and 39 a lateral offset of the closing element 5 in the direction of the clamping element 31a is shown.
  • the pivot arms 36a and 36b are crossed and arranged one behind the other, so that the respective actuating spaces 38a and 38b are formed in the inlet position.
  • the Figures 40 and 41 show an arrangement in which the closing element 5 from the in Figure 38 position shown has moved into the intermediate space 16 formed between the functional surfaces 30a, 30b of the clamping device 11.
  • the lateral offset of the closing element 5 is already slightly compensated for by the functional surface 30a, the functional surface 30a quasi-centering the closing element 5 and guiding it in the direction of the rotary latch 6.
  • the rotary latch 6 is arranged in its closed position and is in engagement with the pawl 7.
  • the closing element 5 is on the buffer element 27 (see for example Figure 47 ) arranged adjacent, which limits a movement of the closing element 5 in the direction of the rotary latch 6.
  • the buffer element 27 thus blocks a movement of the closing element 5 in addition to the rounded sections 33.
  • the respective guide-retaining sections 21 are inclined and arranged to run towards one another in a direction pointing away from the rotary latch 6. As a result, the guide retaining sections 21 block a movement of the closing element 5 in a direction pointing away from the rotary latch 6.
  • the pawl 7 is in engagement with the rotary latch 6 arranged in its closed position, the closing element 5 being arranged in the mouth of the rotary latch 6 so that the rotary latch 6 engages around and fixes the closing element 5 in sections.
  • the rounded sections 33 forming the clamping section 34 of the respective clamping elements 31a, 31b block a movement of the closing element 5 to the side edges of the inlet slot 10 so that the clamping device 11 holds the closing element 5 fixed in its clamping position.
