Definitions
- the present invention relates to a lock cylinder of a lock device according to the preamble of claim 1, a corresponding lock device according to claim 9, in particular for a vehicle, a method for the production of a lock cylinder according to claim 10 and an insertion method according to claim 1 1 for the insertion of a key in a keyway of a lock cylinder.
- lock cylinders are used for a mechanical lock device.
- lock cylinders usually have a cylinder core which is mounted rotatably about a locking axis to a housing.
- a plurality of blocking elements are provided, which can prevent or release the rotation of the cylinder core between a blocking position and a release position.
- This way is a Lock or unlock the door provided with the corresponding lock device possible.
- a correlating mechanical key is usually necessary with the geometric dimension of the blocking elements.
- the individual locking elements are often biased with spring devices in the direction of the locking position.
- a disadvantage of known lock cylinders is that upon insertion of the key into the corresponding key channel, the insertion force from locking member to locking member increases, which is sometimes considered to be hooking and thus disturbing.
- the key is inserted into the keyway, reaching the first locking member.
- the first locking member is displaced by the key in the keyway usually against a bias of a spring device. This spring force must be overcome when inserting the key.
- a displacement of both locking members must be done simultaneously against corresponding spring biasing forces.
- a lock cylinder of a mechanical lock device has a cylinder core, which is mounted rotatably about a locking axis in a cylinder housing.
- a locking axis in a cylinder housing.
- the locking members release the rotation of the cylinder core in a release position and lock the rotation of the cylinder core in a locked position.
- the cylinder core on a keyway for the introduction of a key for the movement of the locking members between the release positions and the locking positions.
- a locking cylinder according to the invention is characterized in that at least two locking member distances are unequal.
- a driver on the cylinder core in particular a shaft on the cylinder core, is provided.
- This driver can mechanically interact mechanically with a Gegenmit repertoire on the mechanical lock device or other components.
- An inventive lock cylinder can be based on known locking cylinders in terms of its basic closing and locking functionality. In this case, different actual mechanical embodiments of the blocking elements can be used.
- the most common locking members, both of which are conceivable as possibilities for carrying out the present invention, are, on the one hand, locking members in the form of pins, which are inserted from outside into the cylinder core.
- the pins of a locking member are at least two parts and have a guide means and a core, wherein the guide means (also called housing pin) for guiding the core and the core directly with the key or a recess in the key, especially in the key bit, mechanically cooperates ,
- the guide means also called housing pin
- blocking elements in the form of closing plates are conceivable, which interact mechanically with the key, in particular the key bit, and are completely accommodated within the lock cylinder and unfold the blocking effect radially outward.
- the locking members are conceivable, provided that they do not leave the basic methodology of a lock cylinder.
- a combination of the two previously presented embodiments of the locking members (pins / closing plates) in the present invention is conceivable, whereby the burglar resistance is increased.
- the key in particular the key bit, itself has a profile with longitudinal grooves, which is designed exclusively geometrically complementary to the keyway in the lock cylinder.
- each key with its corresponding key bit can be inserted into the key channel.
- only key with the geometrically complementary designed (cross-sectional) profile can be introduced into the keyway in the lock cylinder, whereby the break-up security can be further improved.
- the locking devices described later are provided in each case in order to provide a bias in the direction of the blocking position. However, this is not necessarily necessary. Rather, it may be sufficient in individual cases, if individual blocking elements are already moved by gravity into the respective blocking position or are arranged in this.
- the blocking element distances are at least partially unequal. Under a barrier distance is the distance between individual locking members to understand each other, which is aligned along the locking axis of the cylinder core. If, for example, the blocking elements are designed as locking pins projecting from the cylinder housing into the cylinder core, these pins are usually provided with a tip. The distances between these two adjacent peaks define the respective gate distance. In this case, the blocking elements can be arranged in different directions in the lock cylinder, so that they also act in different directions on the key. However, it is also conceivable that all locking elements act on the key from the same direction. Only all blocking elements from the same direction can act on the key.
- the blocking elements are arranged along an insertion axis of the key, which extends parallel or on the locking axis.
- the insertion axis of the key is to be understood as the axis which is defined by the insertion movement of the key during insertion into the keyway.
- a key If a key is inserted into the keyway, it will cooperate with all locking devices at its final insertion position.
- the cam of the key corresponding recesses, which coincide with the respective position of the respective locking member at the full insertion position of the key.
- the locking members In the radial direction are in the key insertion in this way in the insertion of the key, the locking members are moved to a position corresponding to the respective release position with the key. Only in this case, according to the release action of the lock cylinder, a rotation of the cylinder core within the cylinder housing and, accordingly, unlock the locking device possible.
- the barrier element distances differ according to the invention decisively from known lock cylinders. Thus, at least two of the blocking member distances are formed unequal. This means that at least two gate distances are different.
- the foremost locking position of the Sch saubarts of the key reaches the second locking member. Due to the unequal design of the locking members, however, the first locking member is not or already no longer in engagement with the second locking position of the lock key of the key at this time and to this position of the key. Likewise, the further insertion of the key follows until the final insertion position. In this final insertion position of the key now all locking positions of the Sch saubart the key are correlated with the corresponding positioning of the locking members.
- lock position of the key of the key it is understood that a key usually has various recesses on the cam having. These depressions define the respective release position in correlation with the key for the respective obturator. These locking positions are thus intermediate positions or latching positions which can be perceived haptically during insertion of the key by correlation with the locking member, in particular when using a spring device.
- the individual blocking elements may preferably be formed from a hard and / or hardened material.
- a so-called drilling protection also called boring plate
- This drill plate can be designed rotationally symmetrical and cooperate with a locking lug as a predetermined breaking point.
- a drilling test on the locking lug which can be arranged in particular on the lock cylinder and holds the drill plate in a predefined rotational position, breaks off when the rotating drill meets the Aufbohrplatte. Then the boring plate starts to rotate with the drill. As a result, the drill can not penetrate further into the keyway, as it no longer unfolds drilling action.
- the cylinder core is provided with a safety cap having a geometric opening in the form of a cross section of the keyway.
- the safety cap is made of a hardened material, particularly hardened steel, to complicate the drilling of the cylinder core and to avoid the introduction of Aufbruchswerkmaschinee in the keyway.
- the safety cap can be porcelain or a Composite to increase safety.
- the safety cap is positively connected to the cylinder core.
- the burglar resistance is increased by the inventive design of a lock cylinder.
- the opening-up method of the so-called "picking”, ie the sensing and individual depression of the blocking elements with corresponding tools, in particular with regard to the finding of the position of the respective blocking member, is made more difficult.
- the purely functional advantages can thus increase the inventive design of the lock cylinder and the burglar resistance.
- all the blocking element distances are unequal.
- the advantages explained with reference to claim 1 can be achieved in this way for all blocking gate distances.
- the advantages according to the invention can thus be achieved for the entire insertion process of the key into the key channel.
- a plurality of usually up to ten locking members may be provided.
- up to nine locking member distances are provided, which are all formed unequal to each other.
- no barrier member spacing corresponds in terms of its geometric extent to another of the remaining blocking member distances.
- a difference parameter is, for example, a fixed geometric extent value.
- a millimeter can be selected as the difference parameter.
- the multiple is to be understood as the integer multiple of the only difference parameter. In this way, a facilitated production is possible. Also ensures in this way safely and easily that the intermediate position, which correlates with the respective locking position of the Schschbarts of the key, do not coincide with each other and thus the desired effect according to the invention can be achieved. Due to the distinction between the individual locking element distances to a single difference parameter, the structural design of a lock cylinder according to the invention is also simplified.
- the unequal barrier gate distances differ from each other by non-integer multiples. This means that even unwanted collapsing can be completely ruled out by unequal locking devices.
- the difference also excludes integer multiples with regard to the distinction. This ensures that when skipping individual key positions, for example, that the second and sixth intermediate positions can not coincide in a cumulative manner. This ensures that, even with a high number of blocking organs, all blocking element distances in accordance with the invention can never coincide in a cumulative manner during the entire insertion process.
- a further advantage can be achieved if, in the case of a lock cylinder according to the invention, at least one spring device is provided for each locking member, which acts on the respective locking member in the direction of the respective locking position with a spring force.
- a coil spring may be provided for the respective spring device.
- the two main types are to be distinguished, as they are explained in more detail in the following paragraph.
- the basic use of a spring device makes it possible to design a lock cylinder according to the invention in terms of its functionality, regardless of the positional orientation relative to the direction of gravity. The flexibility for the use of a lock cylinder according to the invention is increased in this way.
- the spring devices of all locking elements are arranged in the cylinder core or in the cylinder housing.
- the corresponding locking member may be formed, for example, as a closing plate within the cylinder core.
- Corresponding spring devices also in the cylinder core press the closing plates in their locking position radially outward. Only by correspondingly functional interaction with the individual locking positions of a locking bar of a key, contrary to the respective spring device, the closing plate can be moved as a blocking member in the release position. If the blocking elements are designed as locking pins, they usually protrude radially from the outside out of the cylinder housing into the cylinder core.
- the corresponding spring devices are accordingly arranged in the cylinder housing. Also in this variant, by moving the locking members against the spring force of the respective spring device by the insertion of the key, a displacement of the locking members in the release position.
- At least three locking elements are arranged along the locking axis on a first insertion axis of the key, at least three further blocking elements being arranged along the locking axis on a second insertion axis of the key.
- An orientation along the locking axis is to be understood in the sense of the present invention that the blocking elements are arranged on or parallel to the locking axis. Since the insertion process of the key usually follows a straight line in a straight line, the locking members are thus on a first insertion axis, which runs as a straight line parallel to or on the locking axis.
- insertion axes each with at least three locking members in the inventive training are provided.
- the different insertion axes are arranged parallel to each other and to the locking axis.
- the insertion axis from each other radially, so perpendicular to the insertion direction of the key, spaced.
- a lock device in particular for a vehicle, in particular a motor vehicle, comprising at least one lock cylinder according to the invention.
- the invention also includes a vehicle lock device or motor vehicle lock device with the lock cylinder according to the invention.
- the vehicle lock device can be designed as a mechanical steering wheel lock or as a door lock or trunk lock.
- a lock device according to the invention brings the same advantages as have been explained in detail with reference to the lock cylinder according to the invention.
- Such a lock device can form, for example, the door lock, the steering wheel lock or the trunk lock of a vehicle.
- such a lock device may of course have other mechanical components, such as bolts or locking lever.
- Another object of the present invention is a method for the production of a lock cylinder, in particular according to the present invention, comprising the following step:
- Another object of the present invention is an insertion method for inserting a key into a keyway of a Locking cylinder, in particular according to the present invention, comprising the following steps:
- An insertion method according to the invention preferably brings about the same advantages as have been explained in detail with reference to a lock cylinder according to the invention.
- the entry and engagement points do not coincide with the respective locking position of the key lock key, so that accumulation of the forces in the reaction to the correlation with the individual locking elements is substantially completely avoided.
