Definitions

  • the invention relates to an espagnolette lock according to the preamble of claim 1.
  • espagnolette locks are known on the market. Such an espagnolette lock is also known from German Offenlegungsschrift 2 925 147. Due to the coupling between the connecting rod connecting slide and the connecting rod, a correspondingly large free space is required above the trap combined with a relatively large overall height of the lock housing.
  • the object of the invention is based on the task of designing an espagnolette lock of the type in question in a technically simple manner in such a way that, without reducing the espagnolette travel, a space requirement on the lock housing which is reduced above the trap is required.
  • an espagnolette lock of the aforementioned type is created, the lock housing of which can be produced in a reduced overall height, combined with a corresponding material saving.
  • the angled leg facing the cuff is given an arrow-shaped profile with an arrowhead facing the trap.
  • the angled leg of the drive rod connecting slide facing the cuff has a corresponding cross-sectional profile, so that the driving rod connecting slide is immersed in the groove of the trap is possible. So that the latching of these parts is ensured despite the trap being reversible, the latch head has contour-like grooves on both narrow sides.
  • a multi-armed deflection member is provided, the arms being arranged so that when the trap is retracted, an alternately loaded arm can plunge into the profile projection of the groove.
  • the connecting rod connecting slide preferably has an angular design. When the drive rod connecting slide is displaced in the direction of the trap, its angled leg above the trap in the direction of the cuff can move into the open space that is open towards the narrow side thereof. This means that the case and the angled leg running towards the cuff, which is coupled in a suitable manner to the associated drive rod, overlap with one another. The overall height between the trap and the narrow edge can therefore be reduced by the extent of the covering.
  • the change lever spring is advantageously designed as a compression spring. Its end on the link side is in a non-positive connection with one arm of the deflecting member, in such a way that it is tensioned when the nut is actuated to withdraw the trap.
  • the spring wire passing through the compression spring is used for the non-positive connection, which continues beyond the fastening pin on the deflection member into a torsion spring section which loads the trap tail. Accordingly, the change lever spring works in two ways.
  • the change lever spring can be made of the same material in that the spring wire connects to a bend in the last thread of the compression spring.
  • the end of the compression spring opposite the bend is supported on a stationary abutment.
  • the latter is part of a carrier plate of the gear transmission, so that already existing components are used for the support function.
  • the compression spring is loaded when the trigger is moved to retract the latch by a third arm of the deflecting member via the nut actuating slide that is inevitably carried along.
  • the nut is located in a free space of the carrier plate, is loaded by a return spring and is in meshing engagement with the nut. Therefore, the nut actuating slide returns via this return spring after each shift and meshing back to the starting position.
  • the nut is arranged in a bearing housing which is interchangeably inserted in the lock housing. Depending on the distance, a corresponding bearing housing is used, while the nut actuating slide can keep its structure. Then the tooth of the nut engages in the respective window of the nut actuating slide.
  • the bearing housing can also have a fitting plate screw passage hole arranged below the nut.
  • the secure fixation of a hardware label is therefore always guaranteed.
  • the aforementioned nut assembly can also be assigned to espagnolette locks with different backsets, without modification. This applies even to espagnolette locks with the smallest possible backset.
  • the fact that the lower end of the intermediate link is articulated to the actuating arm of the change lever arrangement also contributes to this.
  • the latter is spring-loaded against the direction of a toothed ring comprising the locking member hub of a locking cylinder and can be driven into the toothed ring actuation area by a control edge of the connecting rod connecting slide.
  • the control edge accordingly moves parallel to the cuff and not, as in known designs, in the direction of the cuff, which helps to save space.
  • the actuating arm When the latch is pulled back by alternating actuation, the actuating arm is first activated and then taken along by the sprocket actuating area. In the case of a closing rotation in the other direction in order to be able to lock the bolt, there is no engagement between the actuating arm and the gear rim actuating area. The correct closing operation of the espagnolette lock can therefore not be avoided.
  • the area of application of the espagnolette lock can be increased by a pin that can be uncoupled through a hole in the lock top or bottom between the latch-side arm of the deflecting member and a slot equipped with a corresponding play of the trap, which can be turned around its longitudinal axis.
  • the trap is given particularly good guidance by a guide groove which crosses into the slot on at least one broad side of the trap tail and into which an adapted guide projection of the lock cover and / or lock base protrudes.
  • An advantageous further development is to be seen in giving the angled leg directed towards the cuff an arrow-shaped profile in cross-section with an arrowhead directed towards the trap.
  • the latch head has contour-like grooves on both narrow sides.
  • the turning of the trap is also made possible by the fact that each prong of the forked tongue has a slot, which slots are offset from one another by the turning shift.
  • either one or the other slot is used in that the pin screwed into the trap arm of the deflection member dips into the slot of the trap tail with its end projecting beyond the trap arm. Turning the trap requires the trap to be pushed back so that the pin is aligned with the hole in the lock top or lock bottom. Then the pin can be unscrewed and then the trap can be removed and turned. Then the pin has to be screwed in again, its end then protruding into the other slot of the trap tail.
  • the espagnolette lock has a lock housing 2 connected to a cuff 1.
  • the cuff 1 fastened to one narrow side of the lock housing 2 has a greater length than the lock housing 2 and extends over an upper and a lower drive rod 3 or, respectively, emerging from the lock housing 2. 4.
  • the latter are provided with locking members 5 which cooperate with counter-closing parts, not shown, on the frame.
  • bearing blocks 8 extend from the rear surface of the cuff 1 and continue to form a step in rearward-facing fastening projections 9.
  • the fastening projections 9 projecting over the narrow side walls 6, 7 have a trapezoidal shape such that the base of the trapezium faces the interior of the lock housing.
  • both the lock base 10 and the lock cover 11 running parallel thereto form insertion pockets 12 and 13 on the narrow side walls.
  • the pocket 12 formed by the lock base 10 is obtuse-angled.
  • One angular section 12 'lies against the facing side wall of the fastening projection 9, while the adjoining angular section 12''is supported flatly on the trapezoidal surface opposite the base.
  • the angular section 12 ′′ is equipped with a passage opening 14, which has a threaded bore 15 of the fastening projection 9 is aligned. Otherwise, this threaded hole runs parallel to the cuff 1.
  • the other insertion pocket 13 in turn also has an angular shape.
  • the angle leg 13 'starting directly from the castle ceiling 11 is supported on the facing oblique flank of the trapezoidal fastening projection 9.

  • the outer surface 18 of the bearing blocks 8 is convexly curved.
  • the outer surface of the fastening projections 9 and the insertion pockets 12, 13 formed by angled portions also extend within this convex curvature, cf. 5 and 6. This makes it possible to produce pockets on the doors that are adapted to the shape of the lock housing at the height of the bearing blocks 8.
  • Each bearing block 8 has a projection 19 with an oval cross section for fixing it on the cuff 1, which is inserted into a shape-adapted recess 20 of the cuff and riveted there, cf. 5 and 14 in particular.
  • the lower drive rod 4 is forked in the region of the section crossing the bearing block 8.
  • a longitudinal slot 29 is formed by the two fork tines 4 ', 4' '.
  • Each fork 4 '. 4 ′′ is provided with an angled end section E, E ′, which rest on the lock base 10 and plunge into form-fitting coupling recesses 31, 32 of a drive rod connecting slide 28 lying flat on the lock base 10.
  • the aforementioned longitudinal slot 29 extends, moreover, at the level of a through hole 30 of the cuff 1 for a locking cylinder fastening screw 30 '.
  • a trap 33 is guided between the upper bearing block 8 and the projection 24. This has a trap opening 34 of the cuff 1, head 33 'equipped with a trap slope, to which a trap tail 33''adjoins the housing.
  • a bolt 35 is guided in the lock housing. Its locking head 35 'passes through a cross-section-adapted passage opening 36 of the cuff 1.
  • the lock base 10 and the lock cover 11 hold a support plate 37 between them. This supports a toothed ring 39 in its lower area in a bore 38 facing the lock cover 11.
  • the axis of rotation of the same is designated M1.
  • the bore 38 is crossed by a locking cylinder insertion opening 40.
  • the same is adapted to the outer contour of a profile locking cylinder 41.

  • Two output gear wheels 44, 45 mesh with the external toothing of the ring gear 39.
  • Their bearing journals which are not described in more detail, extend in one piece from the carrier plate 37. In spite of the locking cylinder push-through gap 42 it is achieved that the ring gear 39 at least with an output gear 44 or 45 meshes. The rotation of the output gears 44, 45 is transmitted to an end gear 51 with the interposition of further reduction gears 46-50.
  • the axle journals for the same are also part of the carrier plate 37.
  • the carrier plate 37 thus contains all the pinion functional units.
  • the end wheel 51 meshes with the rack 52, which is guided parallel to the cuff 1 and is located at the free end of the connecting rod connecting slide 28.

  • the drive rod connecting slide 53 controls the interlocking with the interposition of a pivoting lever 56 in such a way that first the connecting rod connecting slide 53 leads the bolt exclusion and then the bolt 35 is taken along. As a result, the locking members 5 can first engage and cause the door to be tightened, so that the locking bar 35 can then move freely into the striking plate recess facing it.
  • the bolt 35 has on its bolt tail 35 'a run-up slope 57 which extends obliquely to the direction of movement of the bolt 35. This is formed by a lateral elevation 35''' of the bolt tail 35 '', which increase 35 '''leads on the lock base 10.

  • the pivoted lever 56 which is mounted around a material-uniform pin 62 of the carrier plate 37, has on its side facing the connecting rod connecting slide 53 a ring gear section 63, the teeth of which cooperate with a toothed strip 64 of the connecting rod connecting slide 53.
  • the rack 64 is located on an extension 65 of the connecting rod connecting slide 53 or the rack 54. When the bolt 35 is closed, this extension 65 extends in front of a locking edge 66 of the bolt tail 35 ′′, cf. Fig. 9.

  • the hook 72 and the counter hook 74 come into contact with one another and entrainment of the actuating arm 71, the pivot pin 70 of which moves upward within the arch slot 69 of the carrier plate 37.
  • the intermediate link 75 is carried along in the upward direction. Its end portion 78, which forms a tappet, acts on the driving shoulder 87 of the first arm 86 of the deflecting member 84. As a result, the deflecting member 84 pivots and takes the latch 33 with it in the lock inward direction via the second arm. During this process, the change lever spring 80 is charged. If the key is brought into the key withdrawal position after the door has been opened, the ring gear 39 rotates back by the appropriate amount. At the same time, the changeable fog spring 80 can relax, pivots the deflection element 84 counterclockwise and drives the latch 33 into its forward position.
  • the locking of the bolt 35 requires an opposite closing rotation.
  • the drive rod connecting slide 28, 53 are driven in opposite directions by meshing.
  • the direction of movement of the connecting rod connecting slides 28, 53 is indicated in FIG. 9 by arrows.
  • the drive rods 3, 4 with the locking members 5 attached to them are dragged along.
  • the pivot lever 56 does not change its position. This means that the connecting rod connecting slides advance with the connecting rods.
  • the extension 65 Shortly before, the extension 65 has also released the locking edge 66 of the locking tail 35 ′′. This is the case after turning a key.
  • the locking of the bolt 35 therefore only begins when the door has been sufficiently tightened by the corresponding locking members. Accordingly, the bolt can also dip into its associated striking plate recess without interference.
  • the pivoting lever 56 is then rotated via the tooth engagement while simultaneously taking the bolt into the pre-closing position illustrated in FIG. 18.
  • the control arm 61 acts on a stop 124 of the carrier plate 37. In this pre-locking position, the key can be removed. Any push-back forces acting on the bolt are directed into the locking cylinder via the tooth engagement.
  • the locking of the bolt 35 is done by the opposite closing rotation.
  • the drive rod connecting slides 28, 53 are driven in opposite directions in the opposite direction of the arrow via the end wheel 51 and the toothed rack engagement.
  • the rack 64 comes out of engagement with the toothing of the pivot lever 56.
  • the bolt 35 is closed, since then the rearward displacement is taken over by the extension 65 by the lower, obliquely directed end edge 65 'acting on the run-up slope 57 of the bolt tail 35' 'and thereby forcing the backward displacement with simultaneous entrainment of the bolt 35.
  • the extension 65 thereby again comes in front of the locking edge 66 of the bolt tail 35 ′′.
