Definitions

  • the invention relates to a key for cylinder locks, with grooves and ribs arranged on the key broad sides for locking system profile variation.
  • the object of the invention is based on the object of designing a key of the type required in a manner that is simple to manufacture in such a way that, despite the fine gradation of the grooves and ribs, there is great clarity.
  • the cross-sectional area of the key shank can be divided into fields by lines concentric to the straight line and straight lines.
  • the key shaft profile is then determined by omitting a few fields, in such a way that the bottom surfaces of the grooves are concentric with the center, while the side walls are formed by beam sections.
  • the beams can have a different angular distribution and the circular lines concentric to the straight line in different distance from the straight line.
  • a key cross-section divided into fields in this way facilitates the production of a wide variety of key profiles, in particular when the fields are provided with numbers.
  • the object of the invention is also achieved in that the side surfaces of the grooves are concentric with a straight line running in the key shank cross section and the bottom surfaces of the grooves are centrally aligned with this straight line.
  • the key shank cross-section into rays and concentric circular lines into fields, and to produce the corresponding grooves and ribs during the production of the key profile by omitting some fields, with the bottom surfaces of the grooves on the through the straight rays lie, while the side walls are formed by the concentric arc lines.
  • a further increase in the possible differences can be achieved by providing a plurality of central straight lines arranged one above the other.
  • the rays running through these and the concentrically aligned arc lines allow an even finer gradation of the key shaft cross-section.
  • a variation here is that the straight lines are laterally offset from one another in the transverse direction.
  • the key 1 partially shown in FIG. 1 has a key shaft 2 extending from the key cord.
  • the key tip 3 is designed in a roof shape in order to enable the key shaft to be inserted into a key channel of a locking cylinder and the pin tumblers to be arranged.
  • the key tip 3 are arranged on one narrow edge 4 closing notches 5 of different depths.
  • the narrow edge 6 of the key shank 2 opposite the narrow edge 4 is rounded, as can be seen from the cross-sectional profile, and in fact it is adapted to the curvature of a cylinder core of normal dimensions.
  • the key 1 shown in FIGS. 1 and 2 is a master key, that is to say a superordinate key.
  • A runs in the middle of the key shaft cross-section according to FIG Just 7. Concentric to this are circular lines arranged at an even distance. Furthermore, rays arranged in the same angular distribution pass through the center, as a result of which the entire key cross section is divided into fields.
  • the key shaft cross-sectional profile illustrated in FIG. 2 is generated by omitting some fields. This results in grooves 10, 11, 12, 13, 14, 15 and 16 arranged on the key broad sides 8 and 9 and corresponding ribs adjacent to the grooves.
  • the grooves 11, 15 are those in which the side walls 11 'and 15' are aligned with the central straight line 7 running in the key shank cross section. This means that these side walls extend on a corresponding beam section, while the convexly curved bottom surfaces 11 ", 15" are concentric to the straight line 7, that is to say they are located on an arc section of a corresponding concentric circle.
  • the side walls 10 ', 12', 13 ', 14', 16 ' run concentrically to the central straight line 7. They are located on corresponding arc sections of the circles lying concentrically to the straight line 7.
  • the bottom surfaces 10 ", 12", 13 ", 1411 and 16", on the other hand, are centrally aligned with this straight line 7.
  • the key cross-sectional profile can be varied in many ways in this way, specifically by omitting corresponding fields formed by the rays and arcs.
  • the subordinate key 17 illustrated in FIG. 3 is designed so that the grooves 10, 14, 15 correspond to those of the key 1.
  • the grooves 18, 19, 20, 21 are designed to be smaller in cross section in that fields 18 ', 19', 20 ', 21' indicated by dash-dotted lines remain on the key profile, as a result of which the grooves 18, 19, 20, 21 differ from the corresponding grooves 11, 12, 13, 16 of the parent key 1. Therefore, a higher-level key 1 can be inserted into the lower-level locking cylinder receiving the lower-level key 17.
  • the number of beams illustrated in FIG. 2 can be increased or decreased. There is also the possibility of varying the distance of the circles lying concentrically to the straight line.
  • the key 22 illustrated in FIG. 4 has two central straight lines 23 and 24 arranged one above the other in the key shaft cross section. Circles are provided concentrically to these. In addition, rays arranged in the same angular distribution run through the straight lines 23, 24, as a result of which the key shaft cross section is divided into individual fields. By omitting corresponding fields, grooves 25, 26, 27, 28, 29 and 30 are formed on the key broad sides. The side walls of these grooves either run centrally on the straight lines 23, 24 or concentrically to these, while the bottom surfaces of the grooves are either directed centrally to the straight lines or are concentric to these.
  • the undercut occurring on the groove 29 can then be omitted if the gusset 29 ′ formed by the two outer, tangent circles and adjacent to the groove 29 becomes part of the groove 29. It is also possible to eliminate an undercut on the groove 26 by cutting two circles to form a gusset 26 'which is then gripped by the groove 26.
  • the key 31 illustrated in FIG. 5 has three central straight lines 32, 33 and 34 arranged one above the other in the key shaft cross section, the straight lines 32, 34 being arranged one above the other at the level of one key broadside 35.
  • the straight line 33 extends in the middle between the two other straight lines 32, 34, but on the other key broadside 36.
  • Circular arcs are concentric to the straight lines 32, 33, 34.
  • straight lines 32, 33, 34 emit rays which subdivide the entire key cross section into individual fields.
  • grooves 37, 38, 39, 40 and 41 are produced by omitting corresponding fields. Their bottom surfaces and side walls lie on the beam sections or circular arc sections.
  • the undercut present in the groove 39 can be avoided if a larger circle is cut around the straight line 34 and intersects the bottom of the groove 39. This creates a gusset 39 'around which the groove 39 becomes smaller.
