Definitions

the invention relates to a lock cylinder, in particular a equipped with a free-running closing member double lock cylinder with a housing, a rotatably mounted in a bearing cavity of the housing cylinder core, which by means of a displaceable when inserting a key into a keyway of the cylinder core of the key tip in a coupling position coupling member the closure member can be coupled, in which coupling position engages a coupling projection of the coupling member in a coupling recess associated therewith of the closing member, wherein the coupling member exits when the key is removed by applying a torque to the closing member from the coupling position.
the lock cylinder according to the invention particularly relates to a double lock cylinder, as he from the DE 10 2009 038 229 A1 is already known.
the lock cylinder described therein has a two-part housing, wherein each housing half forms a bearing cavity in which a cylinder core is rotatably mounted. If the key is not inserted, the cylinder core is locked in rotation by means of tumbler pins. These are displaced by insertion of a suitable key in a release position, so that the rotational lock of the cylinder core is released and the cylinder core can be rotated.
the tip of the key acts on a coupling member which has coupling projections which can enter into coupling recesses of the closure member by sliding the coupling member towards a closing member to rotatably couple the closure member to the cylinder core to rotate upon rotation of the key Cylinder core is dragged.
the coupling member is spring-loaded in the direction of the cylinder core.
a control pin engages in a control recess with inclined edges. If a torque is applied to the coupling member via the closing member, then the control pin can slide along the inclined edge and controls the closing member from its coupling position.
the invention is based on the object to improve a lock cylinder with simple means closing technology.
an oblique edge control of the torque transmission flanks adjacent to one another in the coupling position is provided in order to displace the coupling member from the coupling position when the closing member is subjected to a torque when the key is removed.
Either the coupling projection or the coupling recess or both have torque transmitting flanks forming an inclined surface. If a torque is applied to this inclined surface, then arises a force directed in the axial direction in the direction away from the closing member, which displaces the coupling member out of the coupling position.
a development of the invention which has an independent character, provides that the coupling member is floatingly mounted in a bearing cavity of the cylinder core. According to this embodiment, it is possible to dispense with the return spring provided in the prior art, which displaces the coupling member from the coupling position.
the torque transmission surfaces can form gradient surfaces.
the pitch surfaces have a pitch angle that cause no self-locking of the axially displaceable coupling elements.
the torque transmission surfaces are preferably formed by worm thread pitch surfaces. It can be provided from a facing the closing member end face of the coupling member projecting, extending on different circular arc sections coupling projections.
first coupling element which is coupled rotationally fixed and axially displaceable with the cylinder core.
first coupling element can have one or two radially projecting ribs which lie in corresponding axial slots of the cylinder core.
the first coupling element may have a cup-like receiving cavity, the opening of which is directed towards the closing member.
a second coupling element is mounted, which has the coupling projection or preferably the two coupling projections.
a compression spring is provided between the first coupling element and the second coupling element which unfolds a spring force, with which the two coupling element are spread apart in the axial direction.
Fesselungs provided in the form of pins to tie the second coupling element in therachöhlung.
the pins pass through holes in the pot wall of the first coupling element and engage in peripheral recesses of the second coupling element.
the spring is supported on the one hand on the bottom of the pot and on the other hand in an end-side annular cavity of the second coupling element. From the bottom or the frontal cavity centering can go out, which protrude into the compression spring. Is the insertion of the key, the coupling recess of the closing member is not in an alignment with the coupling projection, the first coupling element can nevertheless be displaced axially from the key tip. Since the coupling projection of the second coupling element can not enter into its associated Kupplungsaus predominantlyung, the second coupling element can not be mitverlagert. This leads to a compression of the Feather.
the cylinder core can be rotated until the coupling projection reaches its escape position to the coupling recess.
the tensioned spring then displaces the second coupling element in the coupling position.
blocking elements are provided which block each relative displacement to each other with a slight relative rotation of the two coupling elements. This has the consequence that in this relative displacement, the second coupling element can no longer move relative to the first coupling element.
the lock cylinder according to the invention has tumbler pins, which cooperates with mounted on the key broad side of the key Codungsmulden.
the key is a reversible flat key. Furthermore, the manipulation of the closing member is made more difficult, since the bearing cavity of the cylinder core is filled with the diametrical wall slots through the closed surface of the first coupling member.
the acted upon by the key tip end face of the lock cylinder is preferably a plane surface. It is designed so that the opening of the keyway is opened in the direction of the closing member of the coupling element.
the lock cylinder shown in the drawings consists of two cylinder housing halves 1, which are connected together by a connecting web 29 to a one-piece housing.
the axial length of the housing can be changed by one or more extension pieces 27.
the use of the individual housing elements 1, 27, 29 takes place by means of fastening screws 30.
Each of the two cylinder housing halves 1 forms a bearing cavity 2.
the two storage cavities 2 are aligned.
a closing member 6 Between the bearing cavities 2 of the two cylinder housing halves 1 is a closing member 6, which is rotatable.
stuck cylinder cores 3 In the two storage cavities 2 stuck cylinder cores 3, which are held there by retaining rings 28.
This cylinder core 3 has a key channel 4 for inserting a key. 5
the cylinder core 3 has in the region of an end facing the closing member 6 a bearing cavity 26 for receiving a first coupling element 7.
the bearing cavity 26 has diametral wall slots 25, engage in the radially projecting, different width ribs 24 of the first coupling member 7.
the coupling element 7 is characterized rotationally fixed and radially bearing-oriented but axially displaceable tied to the cylinder core 3.
the first coupling element 7 forms together with a second coupling element 8, a coupling member to the cylinder core 3 against rotation of the To lock closing member 6 so that the closing member 6 can be dragged in a key-operated rotation of the cylinder core 3.
the first coupling element 7 has a cup-shaped receiving cavity, in which the second coupling element 8 is receiving. From the bottom of the receiving cavity 14 projects from a centering pin 20 which is a centering pin 23 of a Stirn dioxideung the second coupling element 8 opposite. On the two pins 22, 23 is inserted in each case one end of a compression spring 13, with which the two coupling elements 7, 8 are acted upon each other away.
the wall of the recess 14 has two opposing bores 21, in which tethering pins stuck 20 which enter into FesselungsausEnglishept 19 of the outer edge of the second coupling element 8 to tie the two coupling elements 7, 8 to each other.
a beveled blocking stage 15 In the region of the wall of the receiving cavity 14 is a beveled blocking stage 15.
the blocking stage 15 is flanked by two angular edges 16.
the two angular edges In the in the FIGS. 8 to 12 shown operating positions extends a transition edge of a flat edge 18 to the end edge 17 of the second coupling element 8 parallel to the extension direction of the blocking stage 15. In this operating position, the two angular edges are spaced from the flat side edge 18. If an axial force is applied to the second coupling element 8 in the direction of the first coupling element 7 in this position, the second coupling element 8 can dip into the receiving cavity 14.
the planar flank 18 slides along the blocking stage 15.
the spring 13 is compressed. It can be in the Figures 17 and 18 left illustrated operating position of the two coupling elements 7, 8 formed coupling member can be achieved.
the second coupling element 8 has two from its facing the closing member 6 end face projecting coupling projections 9, 9 '.
the exemplary embodiment involves area-like torque-transmitting flanks 10, 10 ', which rest in a coupling position on corresponding torque transmission surfaces 12, 12', which are formed by the narrow side surfaces of arcuate coupling recesses 11, 11 'of the closing member 6.
the torque transmitting surfaces 12, 12 ', 9, 9' are designed so that a torque which is exerted by the closing member 6 on the second coupling element 8, exerts an axial force on the second coupling element 8.
the operation of the lock cylinder is the following: Starting from the in FIG. 7 shown operating position in which the coupling projections 9, 9 'of both coupling members 7, 8 are in alignment with the coupling recesses 11, 11' of the closing member 6 in the keyway 4 of the right cylinder core 3 inserted a matching key, so his key tip 5 'by attack on the flat surface 7 'of the first coupling element 8, the entire coupling member 7, 8 relocate such that the coupling projections 9, 9' in their associated coupling recesses 11, 11 'occur.
the left cylinder core associated coupling member 7, 8 has an arbitrary operating state. In the in FIG. 7 shown position engage the coupling projections 9, 9 'in the coupling recess 11, 11' of the closing member 6 a. Since no key is inserted into the left cylinder core 3, the floating in the bearing opening 26 mounted coupling member 7, 8 is axially displaceable. Now, if the inserted into the right cylinder core 3 key is rotated, the torque transmission surfaces 10,10 ', 12, 12' of the left coupling member 7, 8 slide against each other.
the coupling projections 9, 9 'of the right coupling member 7, 8, however, can not escape from the coupling recesses 11, 11', because the key inserted there locks a Axialverlager ein the first coupling element 7 and the second coupling element 8 according to the applied torque with respect to the first coupling element. 7 is motion blocked.
the coupling projections 9 are formed by radially projecting from a central portion 17 of the second coupling element 8 pin.
the torque transmission surfaces 10 are formed by the outer surface of the pins extending on a cylinder jacket surface.
