Definitions

  • the invention relates to a flat key with key reide for a lock cylinder with cylinder core, which in one Housing is rotatably mounted and the key selkanal has the flat key for displacement of tumblers can be inserted at a predetermined insertion depth is that through stop areas on a stop lug between key and key shaft and on one further radially aligned to the direction of insertion, opposite the face of the stop lug, is definable.
  • the invention also relates to a Flat key and a lock cylinder of the aforementioned Art.
  • Every key for a locking cylinder must be in the key channel be positioned exactly so that the key teeth defined key code (the "key secret") correctly transferred to the tumblers of the locking cylinder becomes.
  • the key teeth defined key code the "key secret”
  • For exact positioning of the key in the Key channel are used for stops or stop areas on Key on the one hand and on the cylinder core of the locking cylinder on the other hand.
  • a flat key is known from EP-A-0 377 135, which has two stop areas. So is in the transition area between the key bow and the key shaft the usual Stop nose provided, the end face on the outside of the cylinder core next to the key channel. As a second stop a rib is formed on the flat side of the key, the end face of which is also used as a stop surface to limit the insertion works.
  • the purpose of these measures is to six tumblers provided in the locking cylinder to train within a locking system so that it is also in a five-pin cylinder can be used. This is through the lateral insertion limit on the key reached at a six-pin cylinder through an additional profile recess is free in the key channel.
  • the US-PS 4 805 428 shows a cross section through a Key-lock combination on a lock cylinder basis with profile ribs on the key or in the key channel leading to the axis direction run obliquely.
  • the stop results from the back surface of the key or through a stop surface at the key bow.
  • U.S. Patent No. 4,947,662 relates to an electronic key sel, from whose reed protrude electrical contacts that rest on ring contacts in the locking cylinder.
  • the contacts do not represent stops for the key slot, but could be seen as key-side protrusions.
  • a key according to US Pat. No. 5,156,032 bears in the beard area an electrical resistor that holds the key sideways towered over. Such projections are not in the stop area of the Key provided and do not affect the insertion depth the key into the key channel of the locking cylinder.
  • a key emerges from GB-A-2 072 742, which is used in Transition area between reide and beard over a collar that serves as a stop on the locking cylinder.
  • the key bit has a gradation, the End face rests on a stop surface in the key channel.
  • a flat key and a lock cylinder interact with each other characterized in that the projection is immediate on the stop nose, this protrudes axially towards the key tip or that an axial depression is provided directly in the stop lug is and that on the cylinder core below the opening of the Key channel a recess is provided, in which the Protrusion of the stop nose dips or that on the cylinder core a projection is provided which of the recess in the Stop nose is recorded.
  • the additional occurs here Projection over the stop surface in the longitudinal direction of the key and forms the effective stop on the milling machine, since this doesn't have a corresponding recess in the machine-side stop area.
  • a particularly expedient embodiment is characterized in that that the projection as an inclined stop surface, for example, as a tooth, in the reindeer spout for the key shaft inclined and in the cylinder core a die Inclined or on this or on part of it adjacent recess is provided.
  • This tooth has an end flank inclined towards the tip of the key.
  • the Deepening in the cylinder core takes up this tooth, whereby at one execution the tooth flanks the interior of the recess do not touch and on another version, however, on the Apply a recess with part or all of the surface. It can also have a protrusion on the core and key side e.g. a recess may be provided on the reed to falsify the abutment surface when making duplicate keys be effective.
  • Fig. 1 shows a lock cylinder with key according to the invention in cross section
  • Fig. 2 a Key copy router in a schematic representation
  • Fig. 3 shows a variant 1 and 4 another embodiment of the invention.
  • a key 1 is in a key channel 2 of a cylinder core 3 of a locking cylinder 4. So that the toothing 5 of the key bit exactly with the core and housing pin tumblers 6 corresponds, i.e. the insertion depth of the Key 1 in the key channel 2 on the location of the pin tumblers 6 is precisely coordinated, each key carries 1 on the key grain in its run or transition to the profiled and toothed shaft a stop lug 7, which in fully inserted state of the key 1 on the front bears against the cylinder core 3.
  • a projection 8 now projects beyond the end face the key-side stop lug 7. This projection 8 dips into a recess 9 without closing the bottom thereof touch (Fig. 1). It acts as a stop, as with classic ones Keys that are radial to the direction of insertion of the key aligned end face of the stop lug 7 and not the Projection 8, because this has no function in the recess 9 disappears, or is free through the recess 9.
  • the projection 8 is immediately clear when you do that Principle of key copy milling according to FIG. 2 considered.
  • the Original key 1 as a sample or template and on the other a suitable key blank 11 is inserted.
  • a key direction 12, which leads a router 13, runs along the Teeth 5 of the key 1 and transmits the movements in two axis directions on the milling cutter 13 (e.g. disc milling cutter), which is an exact replica of the teeth 5 on the key shaft of the key 11.
  • the milling cutter 13 e.g. disc milling cutter
  • FIG. 3 shows a projection 15 as an alternative to FIG. 1 on the key 16, which is in a recess 17 of a cylinder core 18 immersed and in contrast to Fig. 1 at the bottom of the Recess 17 is present.
  • the end face of the projection 15 and the recessed position of the base (bottom surface) of the recess 17 form the stop of the key 16, the insertion depth of the key shaft and as a reference level serves in the production of a replacement key.
  • Fig. 2 worked, then a key copy is made, the key-side stop not with the lock-side Stop cooperates at the bottom of the recess 17. It takes place incorrect positioning of the key copy in the key channel. The key copy does not lock.
  • Fig. 4 shows an obliquely projecting tooth 19 as key-side stop, which in a recess 20 in the cylinder core 21 engages.
  • Die Recess 20 can also be a true representation of the tooth shape Be 19, the front tooth flank of the corresponding Slant of the recess 20 creates and so the key 22 positioned.
  • the recess 20 can also be larger than the tooth 19, which then engages in the recess 20 without touching it.
  • the actual stop surface lies then outside the tooth, e.g. in the transition area between Tooth and key shaft.
