Definitions

  • the invention relates to an espagnolette lock with a reduction gear, a lock gear actuable, displaceable parallel to the faceplate connecting rod slide and to a latching lever which can be acted upon by a stop associated with the connecting rod connecting slide, transversely to the faceplate.
  • the object of the invention is based on the object of improving the alternating function in a generic espagnolette lock.
  • This object is achieved in a generic drive rod lock in that a drive rod return spring which is tensioned by a stop surface assigned to the drive rod connecting slide when it is actuated alternately.
  • the elasticity of this connecting rod connecting spring return spring is sufficient to automatically move the connecting rod slide and any existing connecting rod locks back to the neutral position.
  • This stop surface can be formed by a butt edge of the connecting slide.
  • the spring can also be the transmission medium to transfer the rod connecting slide displacement to the change lever.
  • the spring can be in the intermediate position between the bumper edge and the change lever.
  • Another possibility of realizing this idea is that the connecting slide acts directly on the change lever. A cam or a separate step can then be provided on the connecting rod connecting slide, which forms the stop surface which acts on the connecting rod return spring.
  • An advantage of this embodiment is that when the connecting rod slide slide is moved from a neutral position into a locking position, the connecting rod slide return spring does not have to come into effect at all. This spring is only tensioned when the changing operation takes place with the connecting rod connecting slide so that the latch is withdrawn. This has the consequence that the latch spring is relieved. The latch spring then does not need to move the connecting rod connecting slide back to the neutral position. Only the change lever and latch itself are moved back to the pre-closed position by the latch spring. This design is preferred for locks with a roller latch, since this ensures that the latch can be closed in a particularly favorable manner and does not require large forces by running onto a locking plate.
  • the espagnolette connecting slide is moved by a gear transmission.
  • two connecting rod connecting slides which can be displaced in opposite directions are provided, one of which runs along the cuff.
  • the toothed wheel of the last wheel engaging in a toothing of the connecting rod connecting slide has toothing of larger diameter on, the larger-diameter toothing substantially reaching up to the cuff, so that the larger-diameter toothing covers the connecting rod connecting slide.
  • the cam dips through a tooth-free area of the larger diameter toothing of the last wheel when moving the connecting rod connecting slide. This gives a maximum diameter of the larger toothing of the last wheel with a minimal overall width of the lock.
  • the espagnolette lock has a lock housing 2 connected to a face plate 1.
  • the face plate 1 projects beyond the lock housing 2 on both sides and overlaps an upper and lower drive rod 3, 4 emerging from the lock housing 2.
  • These are provided with locking elements, not shown, which also have a door frame side Counter-parts not shown cooperate.
  • a case designed as a roller latch 7 is guided between a lock base 5 and a lock cover 6. Specifically, this is composed of a box-shaped profile section 9 passing through a faceplate opening 8, which is coupled with a latch tail 10 projecting into the lock is. About a vertical axis, the box-shaped profile section 9 supports a roller 11 projecting above it. There is a plug-in coupling between the latch tail 10 and the profile section 9. If necessary, a normally designed latch head with a sloping slope could also be used instead.
  • a nut housing 12 is integrated. This supports a lock nut 13 equipped with a square opening. A slide 16, which is acted upon by a compression spring 15, engages on a protruding nut arm 14. The movement of the lock nut 13 in the counterclockwise direction is limited by a projection 17 of the lock housing 12, on which projection an arm 18 of the lock nut 13 is supported, cf. Figure 3 in particular. Furthermore, the lock nut 13 forms an upwardly projecting latch retraction arm 19 which interacts with a shoulder 20 of the latch tail 10.
  • a support plate 21 is fixed on the lock base 5. This supports a toothed ring 23 in a bore 22.
  • the bore 22 is crossed by a locking cylinder insertion opening 24 for a locking cylinder (not shown) designed as a profile cylinder.
  • the cylinder core axis is offset from the central axis of the ring gear 23, below the same.
  • the ring gear 23 is provided with a radially directed gap 25 for engaging a locking bit of the profile locking cylinder. With the external toothing of the ring gear 23 mesh two output gears A, B of a reduction gear U, the final gear 26 is used to drive two oppositely displaceable connecting rod connecting slide 27, 28.
  • the connecting rod connecting slide 27 is coupled to the lower connecting rod 4 while the opposite connecting rod connecting slide 28 entrains the upper connecting rod 3.
  • the connecting rod connecting slide 28 then still serves to drive the bolt 29 guided below the roller latch 7.
  • the drive means are not essential to the invention and are therefore not illustrated in detail.
  • the retraction of the roller latch 7 by means of the lock cylinder actuation is possible via a change lever 30.
  • the change lever 30 is mounted around a journal 33 of the latch housing 2. This extends in the vicinity of the cuff 1, below the roller latch 7 and Above the last wheel 26.
  • the alignment of the change lever 30 runs approximately parallel to the face plate 1.
  • the change lever 30 is designed with two arms and has the longer lever arm 34 and the shorter lever arm 35.
  • the longer lever arm 34 extends parallel to the face plate 1 and merges at the end a step into an end portion 34 'facing the lock. This plunges into a receiving space 36, designed as a pocket, of the trap tail 10.
  • Two opposite stops 37, 38 are formed by the receiving space 36.
  • the stop 37 acts on the end section 34 'of the change lever 30.
  • the change lever 34 is supported by a fixed stop 39, which in the exemplary embodiment is designed as a grub screw.
  • the grub screw fixed stop 39 passes through a bore 40 of the face plate 1 and is screwed into an internal thread 41 of a bearing block 42.
  • a forend-sided countersunk screw 43 is used to hold it.
  • the free end of the Grub screw fixed stop 39 occurs against a step 44 of the longer lever arm 34.
  • the shorter lever arm 35 forms a shoulder 35 ′ that runs approximately perpendicular to the face plate 1 and lies in the path of movement of an abutting edge 27 ′ of the drive rod connecting slide 27 guided on the face plate 1.
  • a torsion spring 45 is placed on the pin 33 for the change lever 30.
  • One end 45 'of which is supported on a recess 46 of the bearing block 42.
  • the other end 45' ' lies in a relaxed position in front of the shoulder 35' of the shorter lever arm 35.
  • This torsion spring 45 serves as a drive rod return spring.
  • Their spring travel preferably corresponds to the maximum swivel travel of the change lever 30.
  • a lever ratio of 1:10 is provided between the shorter lever arm 35 and the longer lever arm 34.
  • the retraction of the roller latch 7 can be done in a known manner on the one hand by the lock nut 13.
  • the stop 38 of the latch tail 10 acts on the change lever and pivots it.
  • the bolt 29 is closed back from its pre-closing position by key actuation.
  • the ring gear 23 is dragged along in the clockwise direction.
  • the connecting rod slide 27 experiences an upward displacement via the final gear 26 of the reduction gear U.
  • the key can then be in the closed position according to FIG Pull out of the lock cylinder. Then the abutting edge 27 'is in contact with one end 45''of the drive rod return spring 45.
  • the roller trap 7 can be retracted by continuing the closing rotation of the cylinder core in a clockwise direction.
  • the connecting rod connecting slide 27 moves further in the upward direction and acts upon the shorter lever arm 35 of the change-over lever 30, with the end 45 ′′ of the return spring 45 being interposed, connected to a pivoting thereof.
  • Its longer lever arm 34 acts on the stop 37 and pulls the latch 7 back against the force of the latch spring 31 loading it.
  • the drive rod return spring 45 is charged.
  • the latch spring 31 causes the latch 7 to advance with the change lever 30 being carried along. The advance of the roller latch 7 is limited when the change lever 34 acts on the grub screw fixed stop 39.
  • the connecting rod return spring 45 relaxes, the movable end 45 ′′ of which pushes the connecting rod connecting slide 27 back into the basic position according to FIG.
  • the ring gear is rotated via the reduction gear, taking the locking member of the locking cylinder with it, so that the key can then be removed from the locking cylinder without further locking rotation.
  • the leading position of the roller trap is to be changed, this can be done by screwing in or unscrewing the grub screw fixed stop from the faceplate.
  • the fixed stop could also enable quick adjustment, for example via control cams etc.
  • the spring 45 which is acted upon by the abutting edge 27 ', is of such a strength that, when under tension, it can push back both the connecting rod connecting slide, as well as the locking elements connected to it, and the gear mechanism together with the locking cylinder, when the cylinder actuation stops during the alternating actuation.
  • the torsion spring 45 is tensioned due to the small spring travel of its arm 45 '' only when the switch is actuated.
  • the spring is acted upon by the abutting edge 27 ′ on the spring arm 45 ′′ and tensioned.
  • the change lever 30 is shifted, since in the intermediate position of the spring arm 45 'the change lever arm 35 is acted upon at the abutting edge 35'.
  • a butt edge 27 'of the connecting rod connecting slide 27 directly acts on a butting edge 35' of the lever arm 35 of the change lever 30.
  • the push rod connecting slide return spring 45 '' is thereby arranged by a cam 51, which is also arranged on the connecting rod connecting slide 27 is acted upon.
  • the cam 51 comes against the end 45 ′′ of the spring 45.
  • the spring 45 is a spiral spring and anchored on the other side in the lock housing in a rotationally fixed manner.
  • the spiral spring 45 is wound around a pin 33 which at the same time forms the axis of rotation of the change lever 30.
  • the connecting rod connecting slide including the drive gear and any existing connecting rod locks can be returned to the neutral position when the lock actuation is interrupted.
  • a butt edge 35 'of the lever arm 35 of the change lever 30 is acted upon.
  • the trap is then withdrawn.
  • the last wheel 26 has small-diameter toothing 26 ′′, which interacts with correspondingly opposing toothing of the drive rods 27, 28, so that the two drive rods 27, 28 are displaced in the opposite direction by rotation of the gearwheel 26.
  • the last wheel 26 Spaced axially to the axis of rotation of the last wheel 26, the last wheel 26 has a larger toothing. This toothing meshes with a toothing of an upstream drive wheel.
  • the larger-diameter toothing has a peripheral region 26 'which is not toothed.
  • the position of the tooth-free area 26 ' is selected so that when the drive rod lock, in particular the toothed drive, is actuated, it is ensured that the drive gear of the upstream gear always engages in the toothed area of the last wheel. However, it is provided that when the drive rod is displaced from the neutral position shown in FIG. 8 into the locking position shown in FIG. 11, the cams 51 of the drive rod connecting slide 27 dive through the toothless region 26 ′ of the last wheel 26.
  • the connecting rod closing slide 26 runs directly adjacent to the cuff 1.
  • the toothed area of the last wheel 26 with a larger diameter but has such a diameter that it projects beyond the connecting rod connecting slide and protrudes almost up to the cuff 1.
  • the diameter of the larger toothing of the last wheel 26 corresponds approximately to the distance between the cuff 1 and the handle housing 12 or the follower nut 13.
