Definitions
- the invention relates to a locking system with a cylinder lock and a flat key for locking the cylinder lock.
- Locking systems with a cylinder lock and a flat key for locking the cylinder lock are known from the prior art. These systems include cylinder locks with a key channel for receiving a flat key and core pins that can be moved into the key channel.
- cylinder locks with a key channel for receiving a flat key and core pins that can be moved into the key channel.
- It is also known to design the scanning extensions of the core pins in such a way that they are narrower than the base body of the core pin and, in particular, are aligned in the longitudinal direction of the key channel.
- Matching flat keys comprise a coded side surface running along its longitudinal extent with control points arranged along the longitudinal extent, with an incision milling which also runs in the longitudinal direction being provided at at least one control point.
- the scanning extension of the core pin is pressed or pulled in such a way that the core pin releases the parting plane between the cylinder housing and the cylinder core and the key locks the lock.
- scanning extensions can be provided which are arranged offset to the left or right of the central longitudinal plane of the key channel, so that a further possibility of variation is created.
- a locking system comprises a cylinder lock and at least one flat key for locking the cylinder lock.
- the cylinder lock comprises a cylinder core rotatably mounted in a housing with a key channel and core pins movable in the key channel. At least one core pin has at its end pointing in the direction of the key channel a scanning extension which extends in the direction of the key channel.
- the flat key has at least one coded side surface running along the longitudinal extension of the flat key with control points arranged along the longitudinal extension. At least one incision is provided at at least one control point, which is designed to accommodate the scanning extension when the flat key is inserted into the key channel.
- the flat key has a recess which is designed to receive a projection of the core pin when the flat key is inserted into the key channel.
- the features of the locking system are designed according to the invention in such a way that when the flat key is withdrawn from the key channel, the projection is completely removed from the recess.
- the recess is arranged along the transverse extent of the flat key offset to the incision milling.
- the recess can be designed to receive the projection of the core pin, in particular in a form-fitting manner, the projection extending from the base body of the core pin in the direction of the key channel.
- the incision milling of the flat key and the scanning extension of the corresponding core pin can be designed according to the invention in such a way that when the flat key is withdrawn from the key channel, the projection is completely removed from the recess.
- the incision has a guide surface which interacts with a control surface on the scanning extension of the core pin in such a way that when the flat key is removed, the projection is completely moved out of the keyway.
- the projection can be designed in such a way that it strikes against a stop of the flat key when the flat key is withdrawn if the projection is not completely moved out of the recess.
- the longitudinal extension of the incision that is, its extension in the longitudinal direction of the flat key
- the shape of the scanning extension can correspond, at least in the area of a control surface, to the shape of the guide surface of the incision milling, so that the scanning extension can be guided along the guide surface.
- the scanning extension can have a slightly curved or rounded shape in the area of a control surface.
- the shape of the projection can essentially correspond to the shape of the recess, so that in the position in which the scanning extension engages completely in the cutout, the projection engages in a form-fitting manner in the recess.
- the main body of the core pin can preferably be cylindrical, while the scanning extension can in principle be shaped as desired. If necessary, the core pin not only has the scanning extension for engaging in an incision, but also a projection on the base body of the core pin which, however, is set back with respect to the scanning extension.
- a special recess can be provided on the key, offset from the incision, for the positive-locking reception of the projection.
- both the scanning extension and the protrusion of the core pin have to penetrate precisely into the notch or into this special recess, so that the core pin is moved correctly and releases the parting plane of the cylinder lock.
- the scanning extension When the key is removed, the scanning extension is lifted out of the notch.
- the incision milling has a circular arc-shaped cross section - this often results automatically when the incision milling is made by the milling tool.
- the scanning extension of the core pin can protrude beyond the projection by at least that distance by which the projection extends with respect to the base body of the core pin. This ensures that when the key is removed, the core pin is lifted by a sufficient distance so that it is ensured that the projection can leave the recess entirely.
- the base body of the core pin is essentially cylindrical, the scanning extension being narrower than the diameter of the base body and extending therefrom essentially in the axial direction of the base body. As a result, the scanning extension can scan a narrow incision on the key. It can also be provided that the scanning extensions of different core pins are offset from one another in order to scan incision millings which are arranged offset relative to a central longitudinal plane of the key.
- the scanning extension can in particular have an essentially rectangular cross section and be oriented in the longitudinal direction of the key channel.
- the scanning extension can preferably have side surfaces which extend in the axial direction from the base body.
- the scanning extension can essentially have the shape of a rectangular web which extends from a cylindrical base body in its axial direction.
- the projection can be arranged directly adjacent to the scanning extension in the transverse direction of the key channel.
- the transverse direction of the key channel denotes a direction oriented essentially at right angles to the longitudinal extension of the key channel.
- the projection is therefore located directly next to the scanning extension at the tip of the base body of the core pin.
- a groove can also be provided between the scanning extension and the projection.
- the width of the groove can preferably be greater than or equal to the thickness of the scanning extension.
- the thickness denotes the extent of the scanning extension in the transverse direction of the key channel.
- the core pin is pressed into the key channel by a spring force, for example via a spiral spring arranged in the cylinder housing.
- a ferromagnetic element is provided in the core pin, preferably in the scanning extension.
- the core pin can be pulled in the direction of the keyway by a magnetic element in the key.
- a magnetic element can of course also be arranged in the core pin and a ferromagnetic element in the key.
- the scanning extension tapers in the direction of the key channel.
- the scanning extension has the shape of a claw circle, a flattened isosceles triangle, or an isosceles trapezoid.
- the scanning extension can have a flattened tip and leg surfaces extending towards the tip.
- the scanning extension can slide undisturbed along a correspondingly shaped incision, which has the shape of a segment of a circle, a flattened triangle or a trapezoid, and thus does not block the key's removal movement.
- a dedicated control surface can also be arranged on the scanning extension, which is preferably arranged at that point on the scanning extension that is closest to the key channel.
- the control surface can have an outer rounding which corresponds to the inner rounding of the notch milling.
- the projection according to the invention which is preferably arranged next to the scanning extension, can have an engagement surface.
- the engagement surface of the projection can be shaped for engagement in the recess of the key.
- the engagement surface can be arranged essentially parallel to the control surface at the tip of the scanning extension and preferably enclose a right angle with the side surface of the scanning extension.
- the projection of the core pin has a retaining surface extending obliquely to the key channel, and the stop has a corresponding side wall extending obliquely to the longitudinal insertion of the flat key.
- the retaining surface and the side wall can be designed in such a way that the retaining surface strikes the side wall when the flat key is removed if the projection is not completely removed from the recess.
- the retaining surface and the side wall can be undercut in such a way that the core pin cannot be moved in its axial direction when the flat key is inserted.
- the retaining surface can form an angle greater than 0 °, preferably 5 ° to 30 °, particularly preferably 15 °, with the side surface of the scanning extension, and an angle less than 90 °, preferably 60 ° to 85 °, particularly preferably 75 °, with the engagement surface. lock in.
- a bevel can be arranged between the retaining surface and the engagement surface in order to facilitate the introduction of the key.
- the retaining surface When viewed in the axial direction of the base body, the retaining surface can form a flint cut. In conjunction with an undercut flank of the recess on the key, this ensures that the core pin is guided along the retaining surface when the key is inserted and removed and, when the key is inserted, cannot be moved in the recess. This forms another security feature.
- this undercut has the advantage that it can only be detected on the key with great effort and effectively prevents the introduction of a key without an undercut.
- a flat key for such a locking system comprises at least one coded side surface running along the longitudinal extension of the flat key, with control points arranged along the longitudinal extension.
- At least one incision is provided at at least one control point.
- the incision milling can have a first depth essentially normal to the side surface.
- a recess with a second depth essentially normal to the side surface can be provided, with the notch and the recess being offset from one another, in particular next to one another, transversely to the longitudinal extension of the flat key. If necessary, the second depth is at most half as great as the first depth.
- such a key therefore not only has an incision milling with a defined depth, but also a recess which is arranged offset in the transverse direction of the key with respect to the incision milling. This results in several possible variations at this control point.
- the recess can be shallower than the incision milling, and not more than half as deep.
- the core pin which engages positively in the notch and recess to lock the lock, must leave the notch completely when the key is removed. Since the incision milling is at least twice as deep as the recess, it inevitably results that the core pin leaves the recess when it is completely removed from the incision milling. Since the core pin is completely lifted out of the recess via the notch, the recess can be provided with a steep flank or another form of a stop on which unauthorized keys would get stuck.
- the side surface can be a key narrow side of the flat key.
- the side surface can also be a broad side of the flat key.
- the incision milling can be narrower than the side surface.
- it can have an extension of preferably one third of the extension of the side surface transversely to the longitudinal extension of the flat key. Two or more milled incisions can be provided transversely to the longitudinal extension of the flat key.
- the incision milling can be curved and preferably designed essentially in the shape of a circular arc and also form an internal circular arc-shaped guide surface. This design allows the core pin to be guided as smoothly as possible along the guide surface when the key is inserted and removed.
- the recess does not have to be curved or in the shape of a circular arc, but can have a base area which runs essentially parallel to the side surface. This allows a particularly good form-fitting engagement of an authorized core pin in the recess.
- a stop can preferably be formed between the side surface and the recess so that an unauthorized core pin blocks when the key is removed. The side surface can also merge into the recess via a stop.
- the stop can have a side wall which is arranged at an angle of 60 ° to 90 °, preferably 75 ° to 90 °, particularly preferably 90 °, to the side surface. If the angle is less than 90 °, this offers the advantage according to the invention that an undercut is formed so that a core pin formed with a correspondingly matching undercut can no longer be moved in the axial direction in the inserted state.
- At least one ferromagnetic element is provided on the flat key at at least one control point for exerting an attractive force on at least one core pin of the cylinder lock.
- a magnetic element is provided in the core pin.
- a magnetic element is provided at the control point in the key and a ferromagnetic element is provided in the core pin. This eliminates the need to use a spring element, for example a spiral spring, to pretension the core pin. Further magnetic coding is also possible.
- the recess is formed immediately following the cut-out. Alternatively, however, it can also be provided that a web for guiding a core pin of the cylinder lock is provided between the incision and the recess.

- the scanning extensions 5 are designed to scan the milled incisions 6. So that the scanning extensions 5 do not block when the flat key 1 is inserted and withdrawn, the milled incisions 6 have an essentially circular arc-shaped cross section, so that the core pins 4 are guided along the curved base of the respective milled incision 6 to their respective end positions.
- all housing pins 3 are located on the dividing plane between housing 12 and cylinder core 2, so that cylinder core 2 can be rotated in housing 12 and the lock locks.

- the flat key 1 is inserted into the key channel 20 of the cylinder core 2 of a cylinder lock.
- the cylinder lock comprises, in a known manner, a housing 12 with spring-loaded housing pins 3 and a rotatable cylinder core 2 with core pins 4.

- the notch 6 serves to receive a scanning extension 5 of the core pin 4.
- the core pin 4 has a cylindrical base body 19 from which the scanning extension 5 extends.
- a projection 9, which in this exemplary embodiment directly adjoins the scanning extension 5, also extends from the cylindrical base body 19.
- the projection 9 extends from the base body 19 by approximately one third of the length of the scanning extension 5.
- a recess 7 is formed on the flat key 1 for the form-fitting reception of the projection 9.
- the recess 7 is located in the longitudinal extension of the key essentially in the central position relative to the milled incision 6.
- the recess 7 merges into the side surface 23 of the flat key 1 via a stop 8 with a steep flank.
- the notch 6 and the scanning extension 5 are designed in such a way that when the flat key 1 is withdrawn, the projection 9 is completely lifted out of the recess 7.
- the notch 6 has a circular arc-shaped guide surface 11, which interacts with a slightly curved control surface 13 on the scanning extension 5 in such a way that when the flat key 1 is removed, the projection 9 is completely moved out of the recess 7. In the case of unauthorized keys, however, the projection 9 remains hanging on the abrupt flank of the stop 8, so that the key cannot be removed.
- FIG. 4 shows a further schematic three-dimensional representation of a key according to the invention, the core pin 4 not being shown this time.

- the scanning extension 5 has two side surfaces 22 which extend therefrom in the axial direction of the base body 19.
- a projection 9 which also extends from the base body 19 in the axial direction.

- the value of z is about twice as large as the value of y.
- the scanning extension 5 tapers in the direction of the key channel 20, that is to say towards its tip.

- the control surface 13 is also provided with beveled side edges.
- the projection 9 has a specially shaped engagement surface 21 which is arranged essentially parallel to the control surface 13 and essentially parallel to the end face of the cylindrical base body 19.
- the engagement surface 21 forms a substantially right angle with the side surface 22 of the scanning extension 5.
- FIGS. 7a and 7c show a schematic three-dimensional representation of a key-lock combination according to the invention, only the core pin 4 and details of the flat key 1 being shown at a control point.
- the flat key 1 On its broad side of the key, the flat key 1 has a side surface 23 in which an incision 6 is formed. The notch 6 serves to receive a scanning extension 5 of the core pin 4.
- the core pin 4 has a cylindrical base body 19 from which the scanning extension 5 extends.
- a recess 7 is formed on the flat key 1 for the form-fitting reception of the projection 9.
- the recess 7 merges into the side surface 23 of the flat key 1 via a stop 8 with a steep flank.
- the notch 6 and the scanning extension 5 are designed in such a way that when the flat key 1 is withdrawn, the projection 9 is completely lifted out of the recess 7.
- the notch 6 has a circular arc-shaped guide surface 11, which interacts with a slightly curved control surface 13 on the scanning extension 5 in such a way that when the flat key 1 is removed, the projection 9 is completely moved out of the recess 7. In the case of unauthorized keys, however, the projection 9 remains hanging on the abrupt flank of the stop 8, so that the key cannot be removed.
- FIG. 7b shows a schematic three-dimensional representation of the key from FIG. 7a, the core pin 4 not being shown this time.
- the side surface 23 of the broad side of the key on which the notch 6 is located can be seen.
- the width of the notch 6 is approximately 1/10 of the width of the broad side of the key.
- the incision milling 6 has a curved, essentially circular arc-shaped guide surface 11.
- the recess 7 Immediately adjacent to the incision milling 6 is the recess 7, which merges into the side surface 23 via a specially shaped stop 8.
- the side wall 24 of the stop 8 is arranged at an angle of approximately 90 ° to the side surface 23.
- the recess 7 has a significantly smaller depth x compared to the incision 6. In the exemplary embodiment in question, the depth of the recess 7 is approximately 1/3 the depth of the cut-out 6.
- Fig. 8 shows a schematic three-dimensional representation of a further key-lock combination according to the invention, again only the core pin 4 of the lock being shown according to the invention.
- the milled incision 6 with the guide surface 11 and the recess 7 on the key are not arranged directly next to one another, but rather a web 17 lying between them is provided.
- the web 17 serves in particular to guide the core pin 4 of the cylinder lock.
- FIG. 9 shows a schematic three-dimensional illustration of the core pin 4 of a cylinder lock according to the invention according to the embodiment of FIG. 7.
- a groove 18 is provided between the scanning extension 5 and the projection 9, which groove serves to engage in the web 17 described above.
- incision milling is not intended to be restricted to recesses in the key that have been produced by a milling tool, but rather includes incisions in the key side that have been produced in any desired way.
- the invention is not limited to circular arc-shaped incisions, but includes all incisions that are suitable for moving the corresponding core pin in such a way that a projection located on the core pin is moved over a stop located on the key.
- the recess according to the invention can run partially or completely along a side surface of the flat key.
- An embodiment can therefore also be provided in which the recess runs partially or completely along a side surface of the flat key. In the event that the recess runs completely along a side surface of the flat key, the recess thus forms the side surface of the key.
- the first depth of the notch and the second depth of the recess are measured in this embodiment relative to another reference surface, preferably relative to the opposite side surface of the flat key.
- the feature according to which “the second depth is smaller, preferably a maximum of half as large as the first depth” is to be understood in this embodiment as meaning that the extension of the recess relative to the other reference surface is greater than the extension of the Notch milling relative to the other reference surface.
- the second depth of the respective recess determining whether the corresponding core pin can penetrate deeply enough into the cutout of the flat key.
- the second depth of the recess is preferably adapted to the geometry of the core pin. If, for example, the second depth of a recess is not large enough, the case may arise that the projection of the core pin prevents the scanning attachment from completely penetrating the cutout.
