Definitions

  • the invention relates to a contact device for transmitting electrical signals between the lock and key on a cylinder lock with a stator housing, a rotor arranged in this with mechanical tumblers and a key channel, in which contact elements for signal transmission are present in a partial area, and a key with a Integrated electronic information carrier and contact points arranged on the key bit, in a partial area next to the mechanical coding.
  • Cylinder locks of this type are used where the security of the known, purely mechanical cylinder locks no longer meets the requirements and where additional electronic security means are arranged both on the key and on the lock. It is known to equip keys to such cylinder locks with at least one storage element which contains a magnetic or electronic code. A corresponding reading device is located in the lock, which can consist of a simple electronic reading unit or one or more microprocessors. Optical, inductive or mechanical contact elements can be used to transfer the stored data from the key to the lock. Since the key and cylinder lock in such locking devices are exposed to many interfering influences such as dirt, deformation, strong magnetic fields, etc., this often results Malfunctions when using such locks and keys equipped with additional electronic elements. This is particularly true where the stored data is transmitted via optical or inductive contact elements.
  • pin tumblers are mounted in a rotor which can be rotated in the stator housing of the cylinder lock. If the key incisions match the penetration depths of the pin tumblers, the mechanical lock between the rotor and the stator housing is released.
  • an electronic security system is arranged at the end of the key bit.
  • a data carrier ring on the key bit for example in the form of a magnetic strip or with a light or electro-optical dot or strip pattern.
  • a read head is arranged in the area of the data carrier on the key, which makes contact-free contact with the transition of information between the key and lock.
  • the contact or reading unit decodes the data contained on the key and checks it for agreement with the data stored in the lock. If there is a match, the rotary movement of the rotor is released via an electromagnet and a locking element, and the lock can be opened.
  • the number of possible closure variations can be significantly increased by superimposing the electronic system on the mechanical one.
  • the system described here is extremely susceptible to malfunction, since foreign parts can accumulate on the data carrier at the key bit and interfere with or even prevent the transfer of data between the key and the lock.
  • the data stored on the data carrier at the key bit can be intentionally or unintentionally changed by strong magnetic fields or other external influences. As a result, this lock / key system loses considerable security and is extremely susceptible to failure.
  • a lock / key system in which the information is transmitted from the key to the lock via a mechanical contact device.
  • an electronic circuit is housed in the key of the key, which contains, among other things, storage units for electronic coding.
  • Contact rings which are connected to the electronic circuit, are arranged on the key bit.
  • the receptacle housing for the key contains sliding contacts which rest on the contact surfaces on the key bit when the key is fully inserted.
  • an electromagnetic Actuated lock arranged, which is controlled by a locking control, such as a microprocessor. If the data stored in the electronics of the key matches the approval conditions in the locking control, this opens the electromagnetic lock.

  • the contact elements are in the installed state in the areas of the lock in which the contact points arranged on the key bit are positioned when the key is inserted.
  • the contact elements are connected directly to the circuit board, which results in a very compact design in the area of the guide element. Since the guide element has the shape of a circular ring segment of the stator housing, the unit formed by the guide element with the contact elements and the printed circuit board can be inserted radially into the stator housing. This facilitates the installation and removal of the contact device with at least some of the associated electronic components on the lock.

  • a preferred embodiment consists in the fact that the grinding springs are arranged in the range of at most 90 ° on both sides of the withdrawal position of the key channel. Since the withdrawal position of the key channel is identical to the position in which the key can be inserted into the lock, it follows that data can be transferred between the key and lock during a maximum 90 ° rotation of the key in both directions.
  • the symmetrical design of the loop spring elements on both sides of the key channel ensures the generation of an electrical contact between the lock and key in both directions of rotation.
  • the rotor has at least one annular groove in the area of the loop spring elements on the outer casing and there is a space between the loop spring elements and the groove bottom.

  • the microswitch is thus activated before the key is fully inserted into the lock.
  • batteries e.g. by removing the passivation layer in lithium batteries, and other electronic components can be activated before the signal transmission between key and lock begins.

  • the contact elements 55 with the grinding springs 57, 58 are arranged on the lower side of the carrier plate 14.
  • Each contact element 55 has a connecting part 56, which penetrates the carrier or printed circuit board 14 and is connected on its upper surface to the electrical conductors 25, for example by soldering. Furthermore, the pairs of grinding springs 57, 58 belonging to each contact element are guided in the cutouts 68, 69 in the guide element 50.
  • each of the contact elements 55 belonging, for example, according to FIG. 5 has a connecting part 56 and a pair of sliding springs 57, 58 which are arranged on both sides of the connecting part 56.
  • the sliding springs 57, 58 each form an angle of approximately 60 ° with the axis 64, the angle being selected such that the springs 57, 58 in the installed state are approximately tangential to the rotary circle formed by contact points 8 on the key 2 run.
  • the individual wiper springs 57, 58 each consist of an outer spring region 61 and an inner spring region 62. These two regions 61 and 62 are formed in one piece by the springs in the bending points 59 and 60 being bent through approximately 180 °.
  • each loop spring element 57, 58 has a longitudinal slot 36. This creates two contact points on the spring areas 62 which can be moved independently of one another.
  • FIG. 8 shows the guide element 50 which is used in the example according to FIG. 5.
  • the front part of the wall is cut away.
  • This guide element 50 consists of an electrically insulating plastic with good sliding properties.
  • the guide element 50 has the shape of a shell segment and is designed in the form of a bridge.
  • the two side parts 52 and 53 are arranged on both sides of the central web 51 and have bores 65, 66 for the fastening screws 34, 35.
  • the guide element 50 is curved and forms a cavity 67 for the rotor 5.
  • guide slots 68, 69 are machined into the side parts 52 and 53. These serve to guide the contact elements 55.
  • the contact points 8 are arranged on the key 2 on its narrow sides 20 and 21.
  • the contact points 8 are formed symmetrically on both narrow sides 20, 21 and are connected in the same way via the electrical conductors 13 to the electronic components 9 in the key 2.
  • an annular groove 18 is formed on the rotor 5, as a result of which an annular gap 18 is formed in this area between the rotor 5, the stator housing 3 and the guide element 50.
  • the spring areas 62 of the loop spring elements 57, 58 are positioned in the upper areas of this annular groove 18.
  • the grinding spring elements 57, 58 form on both sides of the connecting part 56 or the key channel 6 in the pull-off position tangents to an outer diameter of the rotor 5, wherein they are arranged without contact to the jacket of the rotor 5. There is therefore a gap between the groove bottom 19 on the rotor 5 and the two spring areas 62 of the loop springs 57, 58.
  • the dimensions of the contact section 12 with the contact points 8 on the key bit 7 and of the groove 18 on the rotor 5 are selected such that the narrow side 20 of the contact section 12 protrudes beyond the groove bottom 19.
  • This protrusion is dimensioned such that in the example shown the contact points 8 on the narrow side 20 touch the spring region 62 of the sliding spring 58 when the rotor 5 is rotated and deflect it from its rest position until the desired contact force is reached. This creates the electrical connection between the electronic components 9, 41 in the lock 1 and in the key 2, and data can be transmitted as long as the contact points 8 are connected to one of the wiper springs 57, 58 of a contact element 55.
  • the two exemplary embodiments of the lock 1 shown in FIGS. 1 to 4 and 5 to 8 both have the following advantages.
  • the construction according to the invention enables the pre-assembly of the contact elements 15 or 55 on the carrier or printed circuit board 14.
  • the guide element 16 is inserted radially into the stator housing 3 together with the carrier plate 14 and the contact elements 15 and attached.
  • the guide element 50 and the carrier plate 14 with the contact elements 55 are successively inserted and fastened radially into the stator housing 3. Regardless of the installation of the electrical parts and the contact elements, the entire mechanical part of the cylinder lock 1 can be fully assembled in both exemplary embodiments and tested in advance.
  • the manufacturing process of such locks can be considerably simplified and the reject rate is considerably reduced, since the electrical parts can also be checked independently of the mechanical part.
  • a further improvement in the contact between the contact elements 15, 55 and the contact points 8 on the key bit 7 is achieved by dividing the grinding springs 27, 28 and 57, 58 into two parts which can move independently of one another. This arrangement enables the error rate to be reduced to the level of the second power. Since the Contact elements 15, 55 can only be brought from the outside to the rotating parts of the rotor 5 and the key 2, the installation and removal of the guide element 16 or 50 with the carrier or circuit board 14 and the contact elements 15 or 55 take place without intervention in the mechanical part of the cylinder lock 1. In order to ensure this accessibility, the sliding spring elements 27, 28 or 57, 58 extend at most over the range of 90 ° on both sides of the withdrawal position of the key channel 6 in the cylinder lock 1.
