Definitions

  • the invention relates to a protective cover for the keyway of a Profile lock cylinder, in the cylinder housing at least one cylinder core rotatable is stored.
  • Such protective covers are known in practice in a variety of training. They are mainly used for dirt and moisture rejection, but sometimes also as Securing against attacks on the cylinder core.
  • the object of the invention is the protective cover for the keyway so form; that this also retroactively to existing lock cylinders attachable and its handling is simple and practical.
  • This object is achieved according to the invention in that on the side facing the outside of the profile lock cylinder end face of the cylinder core a projecting beyond the end face of the cylinder housing cover is rotatably disposed, which ends above the keyway and there has a substantially parallel to the transverse extent of the key channel extending stop surface extending with a direction towards the keyway channel Slanted and is provided that on the front side of the cylinder housing a guided in the direction of the key channel and the stop surface on the cover, resiliently displaceable key channel cover is arranged, which pressed when inserting the key in the slope of this in the direction of the key channel while the key channel cover, releasing the key channel, is moved against the spring force.
  • the protective cover according to the invention is characterized by a little expensive Assembly from and through a very simple and reliable handling.
  • the assembly and, of course, the subsequent attachment are simple, because it is only necessary, from the front side of the lock cylinder forth to introduce holes for the leadership of the keyway cover.
  • at least two in the direction of the keyway successively arranged head bolts are provided on the web of the cylinder housing and the keyway cover has on the inside a longitudinal recess associated therewith, in which slide the heads of the head bolts when moving the key channel cover.
  • Another one or two holes are necessary because one or both sides of the head pin, a pin is inserted into the web of the cylinder housing, which serves as a rear abutment for the keyway cover acting on spring.
  • a recess on the Key channel cover be assigned, which together form a dome-shaped Key insertion opening revealed.
  • the figure shows a perspective view of a profile lock cylinder with pulled out cylinder core.
  • the cylinder housing is denoted by 1 and the cylinder core by 2.
  • a cover 4 At the outer side of the cylinder housing facing end face 3 of the cylinder core 2 is a cover 4, the so-called.
  • Core cap provided and rotatably connected to the cylinder core 2, ie the cover rotates during the closing operation together with the cylinder core.
  • This cover ends with a stop surface 6 slightly above the key channel 5. In the direction of this has a slope 7 on the stop surface.
  • the actual key channel cover 8 is slidably mounted (vertically) on the web of the cylinder housing, namely at least two head bolts 10 are arranged in the web area in the direction of the keyway 5 in succession.
  • a longitudinal recess on the inside of the keyway cover is Associated with this is a longitudinal recess on the inside of the keyway cover. 8
  • pins 13 are inserted into the web of the cylinder housing 1, which form the rear abutment for the springs 11.
