Definitions

  • the invention relates to an espagnolette lock according to the preamble of claim 1.
  • 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 a reduced space above the trap requires less space on the lock housing without reducing the espagnolette.
  • 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 saving in material.
  • 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 serves for the non-positive connection, which extends beyond the fastening pin on the deflection member into one the torsion spring loading section continues. 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 also used for the support function.
  • the compression spring is loaded when the handle 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 to the starting position after each shift via this return spring and tooth engagement.
  • 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 ring gear comprising the locking member hub of a locking cylinder and can be driven into the ring gear 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. With 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 use of the espagnolette lock can be increased by a pin that can be uncoupled through a hole in the lock cover or lock base between the latch-side arm of the deflection member and a slot equipped with a corresponding play of the latch, 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 top 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 the Trap of the arrowhead. So that these parts can be pushed into each other despite the trap being reversible, 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 deflecting member dips into the slot of the trap tail with its end projecting beyond the trap arm. Turning the trap requires pushing the trap back so that the pin is aligned with the hole in the lock top or bottom. Then the pin can be unscrewed and then the latch can be removed and turned. Then the pin is 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 the 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 with Bolt members 5 which cooperate with frame-side counter-locking parts, not shown.
  • 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.
  • 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.
  • the angle section 12 ′′ is equipped with a passage opening 14 which is aligned with a threaded bore 15 of the fastening projection 9. Otherwise, this threaded bore runs parallel to the cuff 1.
  • the other insertion pocket 13 in turn also has an angular shape.

  • the outer surface 18 of the bearing blocks 8 is convexly curved. Within this convex curvature also extend the outer surface of the fastening projections 9 and the insertion pockets 12, 13 formed by bends, cf. 5 and 6. This makes it possible to produce pockets on the doors which are adapted to the outline 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 bearing blocks 8 form centering brackets 22 which are immersed in shape-matched edge recesses in the lock base 10 and lock cover 11.
  • the aforementioned centering tabs 22 are flush with the outer surfaces of the lock base 10 and lock cover 11.
  • a threaded bore 25 is provided in the projection 24 for receiving a bolt 26, which is also designed as a screw. The latter runs parallel to the cuff 1, but is oriented at right angles to the other bolts 17, since it is screwed in through a hole 27 in the lock base 10 is.
  • differently designed cuffs 1 with connecting rods 3, 4 can be connected to lock housings 2, which may also have different designs, with easy assembly.

  • 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 head 33 'which extends through a latch opening 34 of the cuff 1 and is equipped with a latch slope, to which a latch 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 region 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.
  • the axis of rotation M2 of the cylinder core of the profile locking cylinder used is eccentric to the axis of rotation M1, below the same, cf. Fig. 3.

  • the drive rod connecting slide 53 controls the bolt closure with the interposition of a pivot lever 56 in such a way that first the drive rod connecting slide 53 leads the bolt exclusion and then the bolt 35 is taken along. As a result, only the locking members 5 can engage and bring about a tightening of the door, 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 elevation 35 '' 'leads on the lock base 10.

  • the support plate 37 with the gear transmission and the change lever arrangement W and the bearing housing 98 represent structural units. If drive rod locks with different backset dimensions are to be created, these structural units need not be modified. Rather, it is sufficient to lengthen or shorten the castle floor and castle ceiling, while the rear area remains unchanged including the bulges. Corresponding reductions and extensions are then to be made for the bolt and the latch and the connecting rod connecting slide 28.

  • 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 takes place by means of an 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, oblique end edge 65 'acting on the run-up slope 57 of the bolt tail 35''and thereby forcing the return movement while taking the bolt 35 at the same time.
  • the extension 65 again comes in front of the locking edge 66 of the locking tail 35 ′′.
