Definitions

  • the invention relates to a key for locking cylinders according to the preamble of claim 1.
  • Such a key is known from the German laid-open specification 3314511.
  • the guide grooves run parallel to one another on both broad areas of the key.
  • the groove bottoms of the guide grooves are inclined to the key plane.
  • the known key has guide grooves, the walls of which run at an angle to the key plane.
  • the groove depth is such that at least a portion of the groove base inclined to the key plane protrudes beyond the longitudinal center plane of the key.
  • a disadvantage of such a key is the material weakening of the key caused by the depth and angular profile.
  • Different profiles of flat keys are known from AS 1030727, PS 2551523, PS 1553582, OS 2637516 and AT-PS 360364.
  • the guide grooves disclosed there have a bottom which runs parallel to the key plane. There, too, the groove walls are partially angled to the key plane.
  • the invention has for its object to develop a generic key to reduce the weakening of the valley.
  • the reference plane for the bottoms of the groove is no longer the longitudinal center plane of the key, but an incline running at an angle to the longitudinal key plane.
  • This slope forms the floor level in which the floors of at least one groove from each of the two broad sides of the key lie.
  • a partial area of a groove base can protrude beyond the longitudinal center plane.
  • the floors are assigned the floors of at least two grooves. One of them runs on the opposite key broadside.
  • the material of the key is strengthened. It is preferably provided that an excellent slope is not broken by any of the grooves. This creates a material bridge - albeit infenitesimal.
  • the groove walls of the opposing grooves preferably run perpendicular to the key broad side surface.
  • the groove bottoms therefore run at an acute or obtuse angle to the groove wall.
  • This provides an optimal, undercut-free design of the guide ribs corresponding to the guide grooves in the key insertion slot of the locking cylinder.
  • all the guide grooves of both the one and the other key broad side surface with their bottoms run on a common slope (floor level).
  • floor level a common slope
  • several floor levels arranged parallel to one another are provided.
  • a floor level is preferably distinguished in that no groove breaks through it.
  • the key preferably has a rectangular cross-sectional profile. It can be designed as a reversible key. When the key is designed as a reversible key, there should also be an excellent floor level, which is not penetrated by any groove.
  • the floors of a multiplicity of guide grooves of both the one and the opposite key broad side surface can run.
  • the grooves can also be assigned to the edge area of the key.
  • a preferred embodiment of the key provides that the floor plane runs through the axis of symmetry, that is, the turning axis of the turning key. In the case of a rectangular cross-sectional profile, one, preferably the excellent floor level, can run through the diagonally opposite edges. If several floor levels are provided, they preferably run parallel to one another.
  • the key shown in Figure 1 has a crest 15 and a beard 16.
  • Reide 15 and beard 16 lie in a longitudinal key plane 7.
  • the two opposite surfaces of the reed 15, like the key broad side surfaces 1 and 2, run parallel to the longitudinal key plane 7.
  • the latter is provided with guide grooves 3, 4, 5, 6 running in the direction of insertion.
  • the guide grooves run parallel to one another and have a groove base 3 ', 4', 5 ', 6' which extends inclined to the longitudinal center plane 7 of the key.
  • the floors 3 ', 4', 5 ', 6' lie on a common floor plane 8, which is inclined relative to the central plane 7 about an axis of inclination 9 running parallel to the direction of extension of the beard 16.
  • the back 24 of the key is essentially flat.
  • the narrow side opposite the back 24 also runs flat on the blank.
  • this side of the key with notches 17 is profiled in a known manner.
  • the notches 17 cooperate with the cylinder pins 21 of a locking cylinder 23.
  • the cylinder pins 21 cooperate with housing pins 22.
  • a common inclined floor plane 8 is provided, which extends in the manner described to the central plane 7 of the key and which is so marked that none of the groove floors 3 ', 4', 5 ', 6' extend beyond this plane 8 extends. Nevertheless, it is provided that at least one groove 3, 4 extends with its groove bottom 3 ', 4' over the central plane 7 of the key. In embodiment 1 (FIG. 3), it is even provided that the grooves 3, 4 assigned to the opposite side faces 1, 2 and 3 project with their groove bottoms 3 ′, 4 ′ over the central plane 7.
  • the groove 5 runs on the same broad side surface 1 as the groove 3.
  • the groove bottom 5 lies on the plane 8.
  • the groove 6 runs in the same broad side plane 2 as the groove 4.
  • the groove bottom 6' also lies on the slope 8.
  • the inclined floor plane 8 does not run through the central axis 9 but at a distance from it. While in the exemplary embodiment according to FIG. 3 the inclined floor plane 8 runs through the diagonally opposite edges of the rectangular profile of the key, the inclined floor plane 8 in the second exemplary embodiment is inclined at an acute angle to the central plane 7. The plane 8 runs only through an edge of the essentially rectangular one Key profile.
  • the floor level 8 is the common level of the floors 4 ', 3', 13 'of the grooves 4,3,13. While the grooves 4, 13 are assigned to the one key broad side surface 2, the groove 3 is assigned to the opposite key broad side surface 1 and penetrates the key center plane 7.
  • a second floor plane 10 is provided parallel to the inclined floor plane 8, in which the floors 5 ', 6' of the grooves 5, 6 of the key broad side surface 1 lie.
  • a total of four inclined floor levels 8, 10, 11, 14 are provided.
  • the excellent floor plane 8 again runs through the diagonally opposite edges of the profile and thus through the central plane 9 of the key.
  • the excellent level 8 is the level of the bottoms 3 ', 4', 5 'of the grooves 3, 4, 5 from both key broad side faces 1, 2.
  • All of the grooves 3, 4, 5, 6, 12, 13 have walls which run at a right angle to the key broad side surface 1, 2.
  • the guide grooves interact with corresponding ribs 18, 19, 20 of the cylinder 23, as shown in FIG.
  • the profile has the preferred configuration that at least one groove 3, 13 of the opposite key broad side surface 1, 2 projects with its groove bottom over the central plane 7, but not over a common floor plane 8, which is inclined to the central plane 7.
  • a groove 25 is provided, which only has a wall 252 ′ running at right angles to the broad side surface 2. An opposite wall is missing because the groove 25 '' is assigned to the edge area of the profile.
  • the floor plane 8, 9, 10, 11 is inclined at a larger angle to the central plane 7.
  • a plurality of substantially equally spaced floor levels 8, 9, 10, 11 are provided, which run parallel to one another.
  • the bottoms 6 ′, 13 ′ of the grooves 6, 13 protrude at least with a partial area beyond the central plane 7. Every floor level is here Groove bottoms assigned by at least 2 grooves, the grooves being assigned to opposite key broad side surfaces 1, 2.
  • the bottom level 8 is assigned the groove 3 of the key broad side surface 1 and the groove 4 of the key broad side surface 2.
  • the grooves 6 and 12 correspond to the bottom level 10 and the grooves 5 and 13 correspond to the bottom level 11.
  • all floors 3 ', 4', 5 ', 6' lie on a common floor plane 8 which runs through the central axis 9 and intersects the central plane 7 in this central axis 9.
  • the profile in FIG. 7 is the profile of a reversible flat key, the profile is symmetrical to the central axis 9.
  • FIG. 8 A further profile of a reversible flat key is shown in FIG. 8. All the floors 3 ', 4', 5 ', 6' also lie there on a common floor plane 8 which is inclined to the central plane 7 Floors 12 ', 13' run parallel to floor level 8.
  • the quotient of the wall depth and the distance of the wall from the edge K is for that key broadside and grooves corresponding to the corresponding floor level.
  • the profiling takes place here according to the ray set.
  • the keys according to the invention interact with locking cylinders which have a negative profile to the key shape, so that there are trained accordingly Ridges protrude into the key grooves.
  • the security of such keys or locking systems increases with the number of possible variations of the associated key.
  • the variation of the locking secret is carried out by double profiling. Firstly, the front edge profiling (notches), which interact with the tumblers.
  • the broad side of the key is profiled in such a way that only identically profiled keys fit into corresponding key insertion channels of lock cylinders. It is therefore a success of the invention that the variety of key cross sections known from the prior art is supplemented by further variation alternatives.
