  • the abutment surfaces 249 are provided, for example, by webs similar to the web 150, which inwardly into the container receptacle 45th protrude.
  • a latching recess 254 is provided, into which the bearing pin 245 engages in the clamping position P.
  • the bearing pin 245 and the recess 254 form a latch 255.
  • the tensioning device 340 comprises a carrying handle 341, which serves as an actuating element for the tensioning device 340.
  • a carrying handle 341 which serves as an actuating element for the tensioning device 340.
  • rollers 348 of a roller assembly 353 are rotatably mounted, which are supported in a clamping position P on an abutment surface 349.
  • the carrying handle 341 is mounted on the dirt collecting container 346 by means of pivoting levers 350.
  • the side legs 344 are pivotally mounted, for example by means of a respective pivot bearing 345 on a respective pivot lever 350.
  • other joints may be provided.
  • the carrying handle 341 could also be mounted on each side leg 344 with, for example, two pivoting levers, pivotably mounted on the dirt collecting container 346.
  • the pivot lever 350 in turn are in turn mounted by means of pivot bearings 342 on the dirt collecting 346.
  • the carrying handle 341 makes substantially a linear movement between the support position T and the non-use position N by.
  • the two rollers 348 move up and down in the receiving groove 161, for example.
  • the rollers 348 are based on the in the FIGS. 26 and 27
  • the pivot levers 350 pivot about the pivot bearings 342.
  • the pivot levers 350 thereby move from the in FIGS. 25 and 26 illustrated upper pivot position in an in FIG. 27 illustrated bottom pivot position across their dead centers, so that over the support by the rollers 348 a clamping force in the direction of arrow 139 is exerted.
  • the gasket 123 is thereby tightened against the inlet housing portion 127.
  • the pivot lever 350 forms part of a lever arrangement 352.
  • the clamping devices 240 and 340 also act as a release device when the respective carrying handles 241 and 341 are adjusted to the carrying position T.
  • the substantially linear plug-in clamping movement during insertion of the dirt collecting container 46 in the container receptacle 45 as in the embodiments according to Figures 13-27 the case, to understand by way of example.
  • the dirt collecting container 46 for example, by an exemplary in FIG. 14 drawn pivot axis 363 is pivoted into the container receptacle 45, for example, based on a pivot bearing with bearing pin and bearing receptacles on the dirt collector 46 and the container receptacle 45, then in the last movement section, for example, the inclined surfaces 360 and the mating contour 361 in the sense of bracing the main filter 49 with the opposite sealing seat act on the inlet housing portion 127.
  • An additional latch, clamping lever or the like can then provide a firm grip of the dirt collecting container 46 in the container receptacle 49 and thus also a tight sealing seat of the main filter 49 on the housing portion 120.
