Definitions

  • the invention relates to a letter punch with a stop rail which is arranged displaceably on its lower part and has a stop for the documents to be punched, which can be resiliently latched in different positions. Stop rails are used to punch documents of the same format in the same place, so that a clean letter deposit and easy leafing through a stack of documents is guaranteed.
  • the invention is therefore based on the object of providing a stop rail for a punch hole punch which is also suitable for large document formats, has sufficient rigidity for its handling in the extended state and can be fully inserted into the lower part of the punch.
  • the rail having the stop for the documents to be punched is displaceable in an additional guide rail and can be locked with it in different positions, while the guide rail in turn can be moved longitudinally to a limited extent in the bottom part of the punch hole and can be latched into the lower part in the extended position .
  • the guide rail can also be snapped into different positions in the lower part and expediently has a rectangular profile.
  • the guide rail is in a part which overlaps the lower part of the letter punch, e.g. arranged between the webs of a schnitzel pan.
  • the guide rail 1 which has a rectangular profile, has webs 11, 12, 13 connecting the side walls on its underside and cutouts 14, 15, 16 on its essentially closed upper side.
  • recesses 17 On the inner surfaces of the two side walls recesses 17 are recessed, which serve the side cams 22, 22 'of the stop rail 2 as notches. In the rear area of the guide rail 1, this has two protrusions 18 projecting beyond its upper side, which limit the displacement of the guide rail 1 in the channel of the chip tray 3, which is laterally delimited by the webs 31, 31 ⁇ , by the stop of these lugs 18 on the crosspiece 32.
  • a downward protruding wart-shaped cam 19 On the web 13 connecting the two side walls of the guide rail, a downward protruding wart-shaped cam 19 is provided, which engages in recesses 33 provided on the underside of the guide channel of the chip pan 3.
  • the stop rail 2 has at its front end also serves as a stop for the writing material handle 21 and in the region of its rear end on each side wall a protruding cams 22, 22 ', which in the individual recesses 17 on the inner surface of the side walls of the guide rail 1 click into place.
  • the stop rail has two longitudinal recesses 23, 23, between the two cams 22 and 22 ⁇ , which allow the two cams 22, 22 ⁇ to spring inwards.
  • the stop rail 2 has a nose 24 projecting over its upper side, which limits the longitudinal movement of the stop rail 2 by a stop on the front boundary edge of the recess 15 of the guide rail 1.
  • the wart-shaped cam 19 and the recesses 33 receiving it are dimensioned with respect to the latching of the stop rail 2 in the guide rail 1 so that the latching of the stop rail 2 in the guide rail 1 is only released when the lugs 18 of the guide rail 1 against the crosspiece 32 of the schnitzel pan 3.
  • the nose 24 of the stop rail 2 can be pushed down a little when moving the stop rail 2 in the guide rail 1 when sliding along the inner surface of the upper side of the guide rail 1, so that when it gets into the region of the recess 15, it springs back again and thus preventing further pulling out of the stop rail.
  • the locking connections between the guide rail 1 and the guide channel of the lower part 3 and between the stop rail 2 and the guide rail 1 should be so be dimensioned so that during the pull-out process either the guide rail 1 or the stop rail 2 is completely pulled out before the other rail can be pulled out.
