Definitions

  • the invention relates to a flat key and or or lock cylinder with a rotatable in a housing cylinder core, which is penetrated by a key channel and with a protruding into the key channel, rotatably mounted in the cylinder core body, in particular a gear or a turnstile Transmission of a rotary movement when inserting and / or removing the key into or out of the key channel, which engages in the flat key, in particular in a toothing or a row of holes.
  • a core-side turnstile engages in a row of bores in a key in the manner of the kinematics of a rack and pinion connection.
  • the hole spacing must be matched to the geometry of the turnstile and both must be at the same height so that a key can be fully inserted into a key channel. If a plate is inserted in place of a key for the purpose of manipulation, then the key channel is blocked by the arm of the turnstile which rotates into the key channel and abuts against the plate. This further complicates scanning.
  • the invention aims to assign a locking function between the cylinder core and the cylinder housing to a body which rotates into the key channel and cooperates with the key, in addition to its interaction with the key.
  • a flat key and / or a lock cylinder of the type described above in that the rotatably mounted body is fixedly connected to an axis of rotation and the axis of rotation is displaceable in its axial direction and at least at one end beyond the cylinder core in a recess of the Housing can be inserted and that the flat key has a toothing or row of holes arranged obliquely to the longitudinal axis of the key along a hole track, or as a row of holes or within the same, at least two holes at different heights has on the key longitudinal axis or at least one hole with an increasing control surface or control edge for the additional transmission of an axial movement, in particular a lifting movement to the rotatably mounted body and on its axis of rotation.
  • the rotatably mounted body is not only rotated by form-fitting rolling on the surface or by engaging or reaching through or by the key, but also changes its height.
  • the axis of rotation which is fixedly connected to the rotatably mounted body, rotates about its axis during the insertion of a key into the key channel and at the same time moves upwards or downwards. In its starting position, it dips into a recess in the housing and thus blocks the rotation of the core.
  • the ascending track (hole track) on the key lifts the axis of rotation, which acts as a core pin, out of the recess, so that the rotation of the core in the housing is free. This raising or lowering against spring force takes place continuously when the row of holes is oriented ascending or descending.
  • the row of holes runs horizontally, for example, and only the hole last effective during insertion raises the rotatably mounted body, in particular the turnstile, be it with four, five or six arms.
  • the axis of rotation lies in a bore which follows a chord of the circular cross section of the cylinder core, if the length of the axis of rotation corresponds to the length of the chord and if the axis of rotation by the rotatable body engaging with the key comes from a locking position projecting beyond the cylinder core can be pushed into a position in which the axis of rotation lies entirely within the enveloping surface of the cylinder core.
  • the rotating body e.g. B.
  • the turnstile lifted too high by a key hole then the axis of rotation plunges into another recess at the opposite end. It is therefore expedient if the bore in the cylinder core is extended into the housing at both ends. The rotation of the core is then released only in a single height position of the rotatable body. This effect can also be caused by a spring-loaded housing on the ascending axis of rotation moving housing pin can be reached.
  • the rotatably mounted body can be spring-loaded in the direction of a locking position.
  • the oblique course of the hole track acts against the spring force.
  • the axial position of the rotatable body changes against the force of the spring.
  • the spring can be omitted because gravity determines the locking position or starting position.
  • a special embodiment is characterized in that the row of holes or hole track, seen in the key cross section, comprises obliquely lying bores which raise or lower it from its basic position when the rotatably mounted body engages.
  • the body slides onto the oblique hole inner surfaces as seen in the key cross section.
  • the axial height of the rotatable body is changed, for example the rotatable body, which is designed as a four-, five- or six-arm turnstile, migrates upwards when the key is inserted into the key channel by sliding onto the inclined surfaces during the engagement or immersion of the body in the key recesses until an end position is reached.
  • an ascending or descending row of holes in the key can also be provided.
  • At least one hole in longitudinal section has approximately the shape of a right-angled triangle, the hypotenuse of which is oriented sloping towards the tip of the key, and the cathets of which run parallel to the direction of insertion of the key or at right angles thereto between the hypotenuse and the back of the key, one arm when turning out of the hole and when tilted, slides up along the hypotenuse and a turnstile or the like. lifts.
  • an arm of a turnstile which is initially in engagement with the hole in the key gradually comes out of engagement; starting from a vertical position to the key, the arm always inclines until it emerges from the hole.
  • the rear edge of the arm slides along the Hypotense of the approximately triangular hole up - the arm and thus the turnstile or the like is raised due to the kinematics.
  • the next arm reaches into a hole before the previous arm comes out of engagement.
  • the rising sole (hypotense) and a vertical edge (cathete) to support the arm are essential for the formation of the hole.
  • the end of the hole towards the back of the key is optional. It is also expedient if the rotatably mounted body is designed as a turnstile with arms angled in the direction of rotation.
  • the rotatably mounted body has radially projecting, possibly angled arms or teeth, which bear bevels in the area of engagement on the flat key or in the area of their engagement in the flat key.
  • the bevels are conical or pyramidal surface pieces, the axis of the cone or the pyramid coinciding with the axis of rotation of the rotatably mounted body.
  • Fig. 1 shows a cross section through a lock cylinder with the rotatably mounted body according to the invention in the locking starting position
  • Fig. 2 with the key inserted in the release position
  • Fig. 3 shows a longitudinal section along the line III-III in Fig. 1 with a key during insertion the key channel
  • Fig. 4 is a flat key in side view with three alternative embodiments of holes or hole arrangements
  • Fig. 5 is a cross section according to line VV in Fig. 4
  • Fig. 6 is a schematic diagram of the flat side of a key bit with holes, which inclines differently to the possibility of variation are and therefore cause different stroke
  • Fig. 1 shows a cross section through a lock cylinder with the rotatably mounted body according to the invention in the locking starting position
  • Fig. 2 with the key inserted in the release position
  • Fig. 3 shows a longitudinal section along the line III-III in Fig. 1 with a key during insertion the key channel
  • Fig. 4 is a flat
  • FIG. 7 as a detail the interaction of a rotatably mounted body with the key in cross section
  • Fig. 8 the view of Fig. 7 from above, with an arm is shown angled and Fig. 9a a special hole shape and Fig. 9b the lifting of an arm in the hole of Fig. 9a in cross section.
  • a cylinder core 2 with key channel 3 is rotatably mounted in a cylinder housing 1.
  • the dash-dotted line 4 indicates the usual core and housing pins, which work together with the teeth of a flat key 5.
  • a rotatably mounted body is provided laterally next to the key channel 3, which engages in the key channel 3 - shown here as a turnstile 7.
  • the turnstile 7 with four or more arms works together with a hole 8 (FIG. 4) in a flat key 5.
  • the arms of the turnstile 7 successively engage in the bores 9 (recesses), so that the turnstile 7 rotates like a pinion along a rack.
  • the turnstile 7 is rotatably arranged on an axis of rotation 10 which is rotatably and axially displaceably mounted in a bore 11 in the cylinder core 2.
  • axis of rotation 10 and turnstile 7 are only indicated by simple lines in FIGS. 1 and 2.
  • the recess 6 allows the height of the turnstile to be shifted.
  • the axis of rotation 10 acts as a locking pin and engages in the starting position (Fig. 1), emerging from the cylinder core 2, under the action of gravity or a spring (not shown) in a groove or bore 12 of the cylinder housing.
  • the hole 8 running obliquely to the longitudinal axis of the key causes the same to be lifted when the turnstile 7 is turned.
  • the stroke H corresponds to the height distance of the first effective bore 9 from the last effective bore 9 in the key 5 (FIG. 4).
  • the stroke can be changed by changing the inclination of the hole track 8, 8 ', 8''.
  • the hole track 8 ''' can also be directed downward if the turnstile 7 is held in its recess 6 in the uppermost position by spring force and when the turnstile 7 is pushed in following the hole track 8''', compressing the aforementioned Spring runs down.
  • the bore 13 then has a locking function for the axis of rotation 10 corresponding to the bore 12.
  • the bore 11 passes through the cylinder core 2 in cross section along a chord.
  • the length of the axis of rotation 10 corresponds to the length of this chord. This results in only a single release position, as shown in Fig. 2, in which the axis of rotation with its two ends just does not protrude from the cylinder core jacket. If the stroke H transmitted by the key 5 is incorrect, then the axis of rotation either does not yet emerge from the bore 12 or is already entering the bore 13.
  • This effect could also be achieved by a spring-loaded housing pin lying in an extension of the bore 12, which rests on the end face of the axis of rotation 10. The release takes place only when the contact surface between the housing pin and the axis of rotation 10 lies exactly in the lateral surface of the cylinder core 2.
  • the spring of such a housing pin causes the positioning of the turnstile 7 at the top in the recess 6 as a starting position, so that a hole track 8 '' 'is expedient for pressing down the axis of rotation 10 and the housing pin.
  • the change in the height of the turnstile 7 can be achieved via the inclined bores and the rising or falling hole track 8, 8 ', 8' ', 8' '.
  • the turnstile 7 can also be formed on the ends of the arms with bevels 14, the turnstile lifting up along the bevels when the arms of the same turn one after the other into the bores 9 of the hole track 8 (FIGS. 7 and 8).
  • recesses or teeth can be provided laterally on the flank of the flat key 5.
  • holes 9 ' are shown as an alternative to the holes 9 of the hole track 8, the last of which is somewhat higher than the others. For the function, it is sufficient if only one hole is at a height distance (H), or if its beard-side bottom surface is inclined, so that the turnstile 7 is raised.
  • FIG. 4 also shows holes 9 ′′ as an alternative to the previously described holes 9, 9 ′, which have an approximately triangular shape.
  • the hypotenuse 15 (FIG. 9a) is designed to rise obliquely from the key bit 16 to the key back 17 ′ towards the key chord 18, while one cathete 19 runs vertically and the other catheter 20 is oriented approximately horizontally.
  • An arm 20 of e.g. five-armed turnstile 7, has a rectangular cross-section. It engages in the triangular hole 9 ′′ at the bottom of the hole, as shown in FIG. 9a; if the key is pushed in further, the arm 20 is inclined (see dashed line in FIG.
  • the slope (hypotenuse 15) is essential, as is a support (cathete 19).
  • the hole 9 '' does not have to have a triangular shape, but can also e.g. have a semi-circular opening.
