Definitions

  • the invention relates to a connecting rod lock comprising a connecting rod which can be displaced between an open position and a closed position in connection with at least one closing element.
  • a lock cylinder a reduction gear between the lock cylinder and the drive rod for moving the drive rod between the open position and the closed position and a locking device for the drive rod, which locks the drive rod in the closed position against displacement in the direction of the open position without introducing torque into the reduction gear
  • a control cam assembly for drive engagement in a cam engagement profiling of the drive rod on a transmission output drive rod drive pinion is appropriate and wherein, furthermore, a stop cam for engaging on an abutment surface of the drive rod is attached to the drive rod drive pinion on the transmission output side.
  • a single control cam is attached to the drive rod drive pinion, which is in drive engagement with the drive rod for a single recess in the drive rod.
  • a stop cam is attached to the drive rod drive pinion, which comes into engagement in a further recess of the drive rod when the drive rod is in its open position, so that the drive rod, which is in the open position and loads towards its closed position is supported exclusively via the stop cam in the recess of the drive rod associated therewith, without substantial supporting forces being introduced into the reduction gear.
  • the locking cylinder is rotated 2 ⁇ 360 ° from a zero or key withdrawal position of the locking cylinder to transfer the drive rod from the open position to the locking position.
  • the locking cylinder is rotated further by 360 °; during this further rotation by a further 360 °, the stop cam then comes into the recess in the drive rod provided for it when the drive rod is at a standstill.
  • the invention has for its object to provide a drive rod lock of the type mentioned a structurally simpler or at least consistently simple construction that allows the transition from the open position of the drive rod to the blocking of the drive rod in the closed position with a lower number of revolutions on the lock cylinder to be able to perform.
  • the espagnolette starting from the open position and accordingly from a zero position (key withdrawal position) of the lock cylinder, reaches its lock position after less than 2 x 360 ° lock cylinder rotation, and that the rest of the lock cylinder rotation corresponds to the rest up to 2 x 360 ° to retract the stop cam in the locked position opposite the locking flank of the limiting finger.
  • the espagnolette drive pinion performs a closing rotational movement of approximately 200 ° when the locking cylinder rotates by 2 ⁇ 360 °.
  • This closing rotational movement of the drive rod drive pinion is used, on the one hand, to shift the drive rod from the open position into the closed position and, on the other hand, to lock the drive rod in the closed position in that the stop cam runs onto the locking flank of the limiting finger.
  • the remaining closing rotary movement of the drive rod drive pinion after the drive rod has entered the closed position must be small, for example approximately 20 °.
  • control cams and the stop cams can project axially with respect to a simple construction from an end face of the drive rod drive pinion, in which case a part of the drive rod carrying the recesses can rest against this end face of the drive rod drive pinion.
  • control cams are connected to one another by a web while maintaining a recess lying between them for the engagement of a projection lying between the two recesses.
  • the espagnolette lock according to the invention can be produced in particular in the form that a transom movable to the direction of movement of the espagnolette or Main bolt is provided and is displaceable between a retracted position and an extended position by the drive rod.
  • the bolt can be driven from the drive rod in such a way that a stationary angular lever is connected to a first arm by a pin-slot connection to a bolt tail of the bolt, and that a second arm of the angle lever , namely a control arm with a control profile of the drive rod is engaged.
  • the control profile can have control surfaces at right angles to the direction of movement of the bolt for extending and retracting the bolt and an end surface which is essentially parallel to the direction of movement of the drive rod for locking the extended bolt.
  • Additional locking of the extended latch can be accomplished by attaching a shoulder to the latch and a shoulder engaging pin on the drive rod, the shoulder engaging pin engaging behind the shoulder after the latch has reached its fully extended position. Due to the simultaneous engagement of the control arm with the end face of the control profile on the one hand and the shoulder with the shoulder engagement pin on the other hand, an extremely stable blocking against a violent pushing in of the bolt is achieved, the supporting forces being distributed within the lock in such a way that there is no fear of damage to the furnishings is.
  • the espagnolette lock can also be equipped with at least one pivot bolt which can be pivoted between a pivoted-in and a pivoted-out position by the drive rod.
  • a toothed rack can be attached to the drive rod for pivoting the swivel bolt, and accordingly a toothed segment can be attached to the swivel bolt.
  • This toothed segment can be attached to a hub part of the hook-shaped swivel bolt.
  • the swivel bolt itself can be part of an additional lock attached to a faceplate of the lock.
  • the lock designed according to the invention can further be equipped with a latch which, in a known manner, automatically engages in a striking plate when the door equipped with the lock slams shut.
  • This case is biased in a conventional manner under spring pressure into a closed position and can be pulled back into an open position either by turning a follower nut or from the lock cylinder.
  • a driver can be attached to the drive rod drive pinion, which, when the locking cylinder is rotated, strikes beyond its zero position corresponding to the open position of the drive rod, against a nose of a drop lever acting on the latch.
  • the latch can basically be of the usual prismatic design, that is to say that the latch in a sectional plane perpendicular to the door lock plane and parallel to the direction of movement of the latch has a triangular cross-section with a latch start slope and a latch latch flank, and furthermore that the latch is essentially parallel to this sectional plane having.
  • the recesses on the trap can be designed as grooves which run parallel to the outer surface of the faceplate and, in the presence of trap guide ribs running along the latch latch flank and along the end faces of the trap, end in front of or on these trap guide ribs.
  • the trap guide ribs thus remain intact and there is no danger that they will get caught in the guides of the cuff when the trap is pulled back.
  • the starting point is a connecting rod lock comprising a connecting rod which can be displaced between an open position and a closed position in connection with at least one closing element, a lock cylinder, a reduction gear between the lock cylinder and the drive rod for moving the drive rod between the open position and the closed position, wherein the reduction gear on the lock cylinder side has a toothed ring which meshes with two output gears arranged downstream of it and has a slot designed to insert the locking bar of the lock cylinder and is open towards the edge, and wherein a drive rod drive member of the reduction gear rotatable about a fixed axis acts on the drive rod via a driving device , further comprehensive a bolt which can be moved transversely to the longitudinal axis of the drive rod between a retracted position and an extended position and can be driven from the drive rod by means of movement conversion means, more comprehensive a case biased by spring force into a closed position, which can be retracted against the spring force from a follower and from the lock cylinder
  • the adjustment of the slide bolt is when pivoting of the slot of the ring gear from its zero degree position by the variation angle range of the locking bar enables that the movement conversion means between the bolt and the drive rod are formed by an oblique slot of the drive rod and a slot follower bolt of the slide bolt and that the oblique slot of the drive rod by a extending in the direction of movement of the drive rod Niche is added, in which the pin of the slide bolt has entered in the closed end position of the slide bolt, and has axial play.
  • the trap is driven by the drive rod.
  • the drive rod is moved from the locking cylinder and takes the trap back with it, the slide bolt standing still in the niche thanks to the play of its pin.
  • This embodiment is burdened with considerable disadvantages: to retract the trap, the drive rod must always be moved. This means additional effort and additional wear and tear in the espagnolette lock and requires additional adjustment of the frame-side locking plates in order to grant the espagnolette-side locking elements a corresponding movement play during the espagnolette movement necessary for the latch retraction.
  • a further disadvantage is that in the open position of the lock when the lock cylinder is set to the key withdrawal position and the key removed, an action on the drive rod, for example as part of an attempted break-in, can lead to a reaction via the gearbox to the lock cylinder, with the result that the tumblers of the Lock cylinder be loaded.
  • the invention has for its object to find a solution while maintaining the variation angle range for the lock cylinder bit and while maintaining the immobility of the slide bolt when adjusting the lock cylinder bar within this variation angle range, in which effects on the drive rod in the open position do not lead to the lock cylinder load and the drive rod when Retrieving the latch from the lock cylinder stands still.
  • a cam assembly attached to the drive rod drive member with two control cams and a stop cam and a cam engagement profile attached to the drive rod with two recesses associated with the control cams and two limiting fingers be formed on both sides of the recesses in such a way that when the toothed ring is rotated within the variation angle range of the locking bar, the driving connection of the control cam responsible for the start of the drive rod displacement from the open position into the closed position with the associated recess is released and the limiting finger associated with this recess interferes with the displacement of the drive rod between the stop cams and the axis of the drive rod drive member in a substantially blocking manner, and that the trap is retractable by a driver of the drive rod drive member.
  • the movement conversion means between the bolt and the drive rod can comprise a conversion lever pivotally mounted on the lock housing, which on the one hand engages with the drive rod in a tooth-like manner and on the other hand is connected to the bolt by a pin / slot connection.
  • the transfer lever is a double lever, which is in engagement with a counter cam with a toothing of the drive rod and has a slot in an arm, which feeds in a pin of the bolt.
  • the toothing can have two drive cams spaced apart by a lost motion, namely a bolt-extending drive cam and a bolt-retracting drive cam.
  • the tooth-like engagement between the drive rod and the transfer lever is formed by a nose of the drive rod on the one hand and two teeth of the transfer lever separated by a tooth notch and that the transfer lever has a latch engagement arm, softer with a pin in an elongated hole of the bolt engages.

  • the hook-shaped swivel bolts 106 are arranged in opposite directions compared to the arrangement according to FIG. 5.
  • the additional bolts are designed as known, pivotable bolt tongues 114 and in FIG. 8 as locking blocks 116.
  • the lock cylinder 1 is in the zero position in which the key can be inserted and removed.
  • the latch 78 is in the projecting position in which it can snap into a striking plate when the door equipped with the lock is pressed shut. This trap is biased into the projecting position by a latch spring 59 (see FIG. 1a).
  • the drive rod 16 is in Fig. 1 and 1a in the open position, ie the highest possible position at all.
  • the latch 18 is in the retracted position.
  • the lock cylinder is rotated counterclockwise by means of the inserted key.
  • the gear A is driven via the ring gear 10, so that the drive rod drive pinion 20 also rotates counterclockwise.
  • the control cam 24 engages in the recess 26 'of the drive rod 16 and presses the drive rod down towards the closed position.
  • the control cam 24 ' comes into engagement with the recess 26 of the drive rod 16, while the control cam 24 emerges from the recess 26'.
  • the drive rod 16 has already reached its closed position shown in FIG. 2 before the stop cam 28 has stepped over the limiting finger 30. This results from FIG. 2 and there in particular from the position of the control cam 24 'with respect to the projection 25 located between the two recesses 26 and 26'. It can be seen there that the drive rod 16 no longer performs a downward movement even before the control cam 24 'Has reached the position shown in FIG. 2. This means, that the stop cam 28 runs with the drive rod at a standstill over the limiting finger 30 and thus reaches the position shown in FIG. 2.
  • the pivot bolt 106 is also pivoted out in the counterclockwise direction, as shown in FIG. 4, in that the toothed rack 108 on the toothed segment 110 of the pivot bolt 106 rolls.

  • the driver 100 which is mounted on the side facing away from the control cam 24, 24 'of the drive rod drive pinion 20, engages with the nose 102 of the latch lever 96 with the result that the latch lever 96 in Is pivoted clockwise and pushes the latch 78 back over the housing 64. It should be noted that during the transition from the position according to FIGS. 1 and 1a on the one hand to the position according to FIG.
  • control cam 24 does not carry out a driving movement on the drive rod 16 since it with the flank of the recess 26 'formed by the projection 25 does not come into contact with driving. There is therefore no movement of the drive rod 16 when the latch 78 is withdrawn from the locking cylinder.
  • the latch 78 has in its end faces 79 grooves 118 which run just outside the faceplate 3 parallel to the faceplate 3 and end at the guide ribs through which the case is guided in an opening in the faceplate. If pressure is exerted on the edge 83 with a flat bar or sheet metal in order to push the latch back, this flat bar gets into the groove 118 and prevents the latch 78 from further retracting.
  • the distance of the groove 118 from the outside of the faceplate 3 is approximately 1 mm when the case 78 is fully extended.
  • FIGS. 11 to 15 A further aspect of the invention is now dealt with below with reference to FIGS. 11 to 15. Analog parts are numbered in FIGS. 11 to 15 with the same reference numerals as in FIGS. 1 to 3.
  • the lock bit 1a is in the zero degree position. It is assumed that the key can be inserted and removed in this zero degree position.
  • the ring gear 10 is also in the zero degree position with its gap 2.
  • the position of a transmission output gear or drive rod drive pinion 20 is defined via the gear wheels 12, 13 and 15.
  • the transmission output gear 20 has 22 cams 24 and 24 'in a dumbbell-shaped arrangement.
  • the cams 24 and 24 ' are intended for engagement with a special profile P on a drive rod 16.
  • the drive rod 16 is connected to drive rod sections 16a and 16b for common movement in the vertical direction.
  • the special profile P there are two recesses 26 and 26 '.
  • the special profile P has two limiting fingers 30 and 30 '.
  • a stop cam 28 is also attached to the transmission output gear 20.
  • the displacement of the drive rod 16 in the vertical direction is brought about by the fact that when the transmission output wheel 20 is rotated, the cam 24 first engages in the recess 26 'and later the cam 24' engages in the recess 26.
  • the reverse process takes place if the drive rod 16 is to be pushed back upwards by turning the gear output wheel 20 counterclockwise.
  • a latch 18 is also provided. This latch 18 can be extended, as shown in Figure 15.
  • a transfer lever 35 (angle lever) is provided. This transfer lever 35 pivots about an axis 34. The upper end of the transfer lever 35 is connected to the bolt 18 by a slot 38a and a pin 40.
  • the drive cam 46 In the unlocked state shown in Figure 11, the drive cam 46 'abuts the counter cam 50 so that the transfer lever 35 is prevented from pivoting counterclockwise about the axis 34. If the Driving rod 16 is moved downward by turning the gear output gear 20 counterclockwise (turning is initiated by the locking cylinder via the gear wheels 12, 13 and 15), the recess 42 first moves over the counter cam 50 and then the drive cam 46 runs on the counter cam 50 on. During the free immersion of the counter cam 50 in the recess 42, the position of the transfer lever 35 is not clearly determined. It can oscillate and, accordingly, the bolt 18 can freely move back and forth.
  • the transfer lever 35 When the drive cam 46 runs on the counter cam 50, the transfer lever 35 is pivoted counterclockwise about the axis 34 and begins to move the bolt 18 to the left in the direction of the position shown in FIG. Even during the beginning pivoting of the transfer lever 35 in the counterclockwise direction, the position of the transfer lever 35 has not yet been clearly established. The transfer lever 35 can still swing. Only when the drive cam 46 has come into engagement with the counter cam 50 with its vertically running edge is the transfer lever 35 prevented from oscillating and the latch 18 is locked in its extreme left position (see FIG. 15). Then the lock is locked.
  • the bolt 18 is retracted when the drive rod 16 moves upwards, the counter cam 50 passing through the recess 42, the flank 50 a being hit by the drive cam 46 and finally the drive cam 46 'again bearing against the counter cam 50, as shown in FIG. 11.
  • the transfer lever 35 can also oscillate again and accordingly the bolt 18 can move in an uncontrolled manner in the horizontal direction.
  • the retraction of the latch 78 results from FIG. 12.
  • the lockable 1a and with it the slot 2 of the ring gear 10 are so far in an approximately + 30 ° position that the trap 78 retreat can begin.
  • a driver 20a is attached to the transmission output gear 20, as can be seen from FIG. This driver 20a is located on the underside of the transmission output gear 20 and therefore does not appear in FIG. 11.
  • the driver 20a is intended to cooperate with an expression 96a which is attached to a latch lever 96.
  • the latch lever 96 is pivotable about the axis 32 of the transmission output wheel 20 and acts with its upper end on a latch tail 58, 64, which is also under the force of a spring 59.
  • the range of variation of the lock bit 1a in the lock according to the invention is therefore limited to the range between + 30 ° according to FIG. 14 and -90 ° according to FIG. 13. This means that - as explained above - the lock bit 1a is varied only in such an angular range can, in which there is no thrust engagement between the cam 24 and the special profile P, and consequently the drive rod 16 and the bolt 18 is not moved. If, nevertheless, a lost motion is provided between the drive rod 16 and the bolt 18, which results from the width of the recess 42 between the two drive cams 46 and 46 'results, this lost motion has nothing to do with the requirement for variability of the opening angle of the lock bit 1a.
  • the transfer lever 235 is modified compared to the embodiment in FIG.
  • This transfer lever 235 can again be pivoted about a fixed axis 234 and has two teeth 237, 239, namely a bolt ejection tooth 237 and a bolt retraction tooth 239.
  • a tooth notch 241 lies between these teeth.
  • FIG. 17 shows a further modification of the gear connection between the push rod 316 and the bolt 318.
  • the position of the Figure 17 again corresponds approximately to the position of Figure 11.
  • the counter cam 350 of the transfer lever 335 positively engages between two correspondingly dimensioned drive cams 346 and 346 'of the drive rod 316.
  • the lost motion between the drive rod 316 on the one hand and the transfer lever 335 and thus also the slide bolt 318 on the other hand is completely suppressed here.
  • due to the unchanged engagement conditions between the cam 324 and the special profile P there is the same variation possibility for the position of the locking bar between + 30 ° and -90 °.
