Definitions

  • the invention relates to a flat key and a Lock cylinder with a cylinder core rotatable in a housing, which is penetrated by a key channel, in the a body rotatably mounted in the cylinder core protrudes and for transmitting a rotary movement when inserting and removing the flat key in or out of the key channel engages in the flat key, the rotatably mounted Body firmly connected to an axis of rotation and the axis of rotation is displaceable in its axial direction and at least on one end beyond the cylinder core into a recess the housing can be inserted and the flat key Transmission means for transmitting an axial movement, in particular lifting movement, on the rotatably mounted body and has on its axis of rotation.
  • locking cylinders and flat keys there are locking cylinders and flat keys known, the latter on at least one flat side over one from the tip of the key to about to the Reide along a grooved line. That groove that functionally corresponds approximately to the key toothing, the Core and housing pins of a locking cylinder so that the cylinder core can be rotated in the cylinder housing.
  • the invention aims to one in the key channel body rotating and interacting with the key, an exclusion function for a wrong key and a locking function between the cylinder core and cylinder housing assign.
  • a flat key is specially designed for one Lock cylinder with a cylinder core rotatable in a housing, which is penetrated by a key channel, in the a body rotatably mounted in the cylinder core protrudes and for transmitting a rotary movement when inserting and removing of the flat key in or out of the key channel engages in the flat key, the rotatably mounted Body firmly connected to an axis of rotation and the axis of rotation is displaceable in its axial direction and at least on one end beyond the cylinder core into a recess the housing can be inserted, and the rotatably mounted body is designed as a gear or turnstile, the Flat key transmission means for the transmission of an axial Movement, especially lifting movement, on the gear or Has turnstile and the transmission means in the flat key as one running along one at an angle to the key axis Hole track arranged row of holes with holes that cross-section of the flat key or a row of holes with at least two at different heights, based on the key longitudinal axis, penet
  • the gear or turnstile is made by positive Unroll along the flat side of a key by engaging or reaching through or through the key not only twisted, but also changed in its altitude.
  • the one firmly attached to the gear or turnstile The axis of rotation rotates when a key is inserted into the key channel around its axis and migrates at the same time up or down. She dives into her starting position into a recess in the housing and blocked so the rotation of the core.
  • the ascending track (Hole mark) on the key lifts the axis of rotation out of the recess out, so that the rotation of the core in the housing is free is. This raising or lowering against spring force takes place with an ascending or descending hole row continuously. In many cases, however, it is sufficient if the Row of holes e.g. runs horizontally and only that with Insert last effective hole the rotatably mounted body, especially the turnstile, be it four, five or six-armed, raises.
  • the axis of rotation is in a Bore that is a chord of the circular cross section of the cylinder core follows.
  • the length of the axis of rotation corresponds to the length the tendon.
  • the axis of rotation is in with the key Engaging gear or turnstile from one of the cylinder core outstanding locking position can be pushed into a position, in which the axis of rotation is entirely within the envelope Surface of the cylinder core lies.
  • Rises the gear or the turnstile too high through the key hole then the axis of rotation appears in a further recess on opposite end. So the hole in the cylinder core is extended into the housing at both ends.
  • the release the core is then only rotated in one Height position of the gear or turnstile. This effect can also be spring-loaded on the housing side reaches the housing pin moving up the rotating axis become.
  • the axis of rotation of the gear wheel or turnstile can be in the direction be spring loaded to a locked position. Against the spring force the oblique course of the hole track appears.
  • the spring can omitted because gravity locked position or Starting position determined.
  • the hole track with a row of holes - in the key cross-section seen - includes inclined bores that engage the gear or turnstile this from its basic position raise or lower.
  • the gear wheel or turnstile is changed in its axial altitude, for example the four-, five- or six-armed turnstile moves when inserted the key into the key channel by sliding it on on the inclined surfaces during the intervention or immersion the arms of the turnstile into the key recesses upwards until an end position is reached. But it can also an ascending or descending row of holes in the Keys should be provided.
  • At least one cross-section between Key back and key bit through hole in longitudinal section approximately the shape of a right-angled triangle has, the hypotenuse as a control edge towards Key tip is sloping and its cathets parallel to the direction of insertion of the key or at right angles between the hypotenuse and the back of the key run, so that one arm of the turnstile when unscrewing out of the hole and when tilted along the hypotenuse slides up and the turnstile lifts.
  • the rear edge slides during the inclination of the arm along the hypotenuse of the approximately triangular hole up - the arm and thus the turnstile will result the kinematics raised.
  • the next arm is already in a hole before the previous arm is still disengaged is coming. This applies to all embodiments. More essential in the formation of the hole is the rising sole (Hypotenuse) as well as a vertical support for the arm Edge (cathete).
  • the completion of the hole up to Back of the key is arbitrary.
  • the turnstile can be in Direction of rotation angled arms are formed.
  • the gear wheel or the turnstile has radially protruding teeth or arms, those in the attack area on the flat key or in the area wear bevels when engaging in the flat key.
  • the inclined surfaces gear or turnstile side as bevels in the form of Cone or pyramid surface pieces are formed, wherein the axis of the cone or pyramid with the axis of rotation of the Gear or turnstile coincides.
  • Fig. 1 shows a cross section through a lock cylinder with the rotatably mounted according to the invention Body in the blocking starting position

  • Fig. 3 is a longitudinal section along the line III-III in Fig. 1 with a key 4 during insertion into the key channel
  • Fig. 5 one Cross section along line V-V in Fig. 4
  • Fig. 6 is a schematic diagram the flat side of a key bit with holes, the inclined to the possibility of variation are and therefore cause different stroke
  • 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, an arm is shown angled and Fig. 9a a special hole shape and Fig. 9b lifting of an arm in the hole according to Fig. 9a in cross section.
  • a cylinder housing 1 In a cylinder housing 1 is a cylinder core 2 with Key channel 3 rotatably mounted.
  • the dash-dotted line 4 indicates the usual core and housing pins, which with the Work together toothing of a flat key 5.
  • a Recess 6 in the cylinder core 2 is on the side next to the key channel 3 a rotatably mounted body in the key channel 3 engages - shown here as turnstile 7 - intended.
  • the turnstile 7 with four or more arms works with a hole 8 (FIG. 4) in a flat key 5 together. The arms grip when the key is inserted of the turnstile 7 one after the other into the holes 9 (Recesses) so that the turnstile 7 is like a pinion turns along a rack.
  • the turnstile 7 is on one Axis of rotation 10 arranged in a rotationally fixed manner, which in a bore 11 in the Cylinder core 2 is rotatably and axially displaceably mounted.
  • axis of rotation 10 and turnstile 7 in 1 and 2 indicated only by simple lines.
  • 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 Action of gravity or a spring (not shown) in a groove or bore 12 of the cylinder housing.
  • Hole track 8 causes due to the key cross section (Fig. 5, Fig. 2) obliquely guided holes 9 with the rotation of the turnstile 7 simultaneous lifting the same.
  • the stroke H corresponds to the height distance of the first effective bore 9 of the last effective bore 9 in Key 5 (Fig. 4).
  • the stroke can be changed by changing the incline the hole track 8, 8 ', 8 "can be changed.
  • the bore 13 then has the Bore 12 locking function for the axis of rotation 10.
  • the bore 11 passes through the cylinder core 2 in Cross-section along a tendon. It corresponds to the length of the Axis of rotation 10 of the length of this tendon.
  • This only results in a single release position, as shown in Fig. 2 is in which the axis of rotation with its two ends the cylinder core shell just not towered over. Is that about the Key 5 not transmitted stroke H, then the axis of rotation dips either not from hole 12 or already in the bore 13.
  • This effect could also be caused by a in an extension of the bore 12 resilient housing pin can be achieved, the front on the axis of rotation 10 is present.
  • the release takes place only when the touch area between housing pin and axis of rotation 10 exactly in the outer surface of the cylinder core 2 is.
  • the feather of one such housing pin causes positioning as a starting point of the rotating core 7 at the top in the recess 6, so that for pressing down the axis of rotation 10 and the housing pin a hole track 8 "'is appropriate.
  • the change in altitude can the turnstile 7 over the boring holes and the rising or falling hole track 8, 8 ', 8 ", 8"' can be achieved. But it can also be the turnstile 7 on the front be formed on the arms with bevels 14, wherein the turnstile rises along the bevels if the arms of the same one after the other in the holes 9 of the Screw in hole 8 (Fig. 7 and 8).
  • the hypotenuse 15 (Fig. 9a) is from Key bit 16 to the key back 17 'obliquely against the Key crest 18 formed increasing, while the one cathete 19 runs vertically and the other cathete 20 is aligned approximately horizontally.
  • An arm 20 of e.g. five-armed The turnstile 7 has a rectangular cross-section. He lies when engaging in the triangular hole 9 "at the bottom of the hole, as shown in Figure 9a; the key continues inserted, then the arm 20 is inclined (see dashed line in Fig.
  • the slope (hypotenuse 15) essential, as well as a support (cathete 19).
  • the hole 9 “need not have a triangular shape, but can above the slope (15) also e.g. a semicircular Possess opening.
