Definitions

  • the invention relates to an espagnolette lock with a central lock and a key-operated lockable and lockable main bolt, from which central lock a drive rod extends for actuating an additional lock with lockable and lockable locking bolt, the locking bolt drive of which is coupled to the drive rod movement.
  • Such drive rod closures are known on the market. Along with a lock actuation of the main lock, the drive rod emanating from it is shifted, which in turn controls the locking bolt of the additional lock via transmission means.
  • DE 35 03 466 C2 shows an espagnolette lock, which includes both a central and an additional lock.
  • the locking bolt is locked there using a handle. This can also be used to withdraw the pre-locked bolt. Furthermore, it is possible with this configuration to retract the locking bolt by actuating the central lock.
  • the object of the invention is based on the object to design a generic drive rod lock with multiple locking so that the opposite the locking bracket function known from DE 35 03 466 C2 is advantageously improved in use.
  • the additional lock is designed as a locking shackle lock, that in the closed position, the locking pin drive can be uncoupled from the drive rod movement in a closed position and shifted into a locking yoke catch position and that the locking pin drive is coupled to the connecting rod return movement after the connecting rod has been pulled to retract the locking pin.
  • a generic drive rod closure of increased utility value is specified.
  • the locking bolt can be locked and closed by means of the central lock via the displacing drive rod.
  • the locking bolt drive can then be uncoupled from the drive rod movement in a handle-operated manner.
  • the locking bolt can be displaced into the locking bracket catch position by means of a handle on the inside of the door.
  • a door equipped with the espagnolette lock according to the invention can then only be opened a gap. From this pre-closed position of the locking bolt, it can also be moved back again by means of the handle, the locking bolt coming to the locking bracket in the release position.
  • the locking bolt drive is connected to the Drive rod return motion coupled.
  • the bolt cannot then be withdrawn by means of the handle assigned to the additional lock, but only by moving the connecting rod.
  • the measure increases the security that the locking bolt has stepped into a locking position to a striking plate on the door frame when the driving rod is completely advanced in front of the locking bracket catch position.
  • the locking bolt is not only fixed by the locking bracket, but also by the striking plate in such a way that the free end of the locking bolt engages behind a shoulder thereof.
  • the different degrees of pre-locking of the locking bolt is achieved in a simple manner by a connecting rod connecting slide of the additional lock coupled to the connecting rod, which has a stop against which a counter-shoulder of the locking bolt occurs when the locking bolt connection is operated. If the locking bolt is pre-locked in a manipulated manner, this stop limits the locking of the same. In this position, the locking bolt is in the catch position and thus allows the door to be opened wide. If, on the other hand, the locking bolt is locked by moving the connecting rod, the stop moves out of the path of movement of the counter-shoulder and thus allows the locking bolt to be closed to a greater extent, which then engages with the locking plate supporting the locking bracket.
  • the locking bolt causes centering, so that the trailing bolt of the central lock has already assumed its aligned position with the locking engagement opening of the locking plate assigned to it.
  • the locking bolt exits until shortly before the locking bar catch position, in which a locking pin-side constriction in the rebate clearance and the end section with a larger cross section lies in the locking bracket. This measure further increases the safety value of the espagnolette lock according to the invention.
  • the constriction lies beyond the barrier. Then the cross-section is supported End section of the locking bolt on a shoulder of the striking plate.
  • the espagnolette 1 shown in the drawings has an elongated cuff 2, which is usually embedded in a groove of a door.
  • a central lock 3 is connected to the cuff 2.
  • This is designed as a mortise lock and has a nut 4 to be coupled with a handle.
  • a latch 5 guided in the upper region of the lock housing can be withdrawn.
  • a main bolt 6 is guided beneath the trap 5.
  • the latter can be closed and closed by means of a locking cylinder 7 located in the lower area of the central lock 3.
  • the latch 5 can be withdrawn by actuating the lock cylinder via a change (not illustrated).
  • the hemp latch 6 is completely pre-closed after the second tour has been closed. This means that two complete locking rotations must be carried out using the key.
  • a drive rod 8 is shifted along with the closing operation. Relocation the drive rod 8 already takes place when the first tour is closed, while the main bolt 6 still remains such that after the first tour the main bolt 6 is still in its closed position while the drive rod 8 has already shifted by a certain amount.
  • An additional lock 9 is connected to the cuff 2 above the central lock 3.
  • This has a lock housing 10. From a lock base 11 of the same go a lock case rear wall 12 and lock case side walls 13 and 14, the end portions of which are connected in a suitable manner to the cuff 2.
  • the lock set-up is covered by a lock cover 15.
  • the lock base 11 and the lock cover 15 store a nut 16 between them.
  • This is equipped with a square opening 17 for receiving a square pin 18, the latter being coupled non-rotatably with a handle 19 on the inside of the door.
  • the handle 19 is mounted in a fitting plate 20.
  • a window 21 which, depending on the rotational position of the handle, is aligned with symbols on the fitting plate side, so that the respective position of a locking bolt 22 guided in the additional lock housing 11 can be seen.
  • the locking bolt 22 is displaceable transversely to the cuff 2 above the nut 16.
  • a through opening 23 of the cuff 2 is adapted to the cross section of the locking bolt 22.
  • the locking bolt 22 is equipped with a constriction 24, which is circular in cross section.
  • the constriction 24 is opposite to this End section 25 with a larger cross section, which rests in the passage opening 23 when the bolt cover 22 is closed.
  • the locking bolt 22 interacts with a striker plate 26 to be fixed on the door frame side.
  • the latter stores a locking bracket 27 in its upper region, which is equipped in a known manner with an entry opening for the locking bolt 22.
  • the constriction 24 is aligned with the longitudinal slot of the locking bracket 27, so that the door can be open to a gap while pivoting the same.
  • the entry opening continues in the striking plate 26.
  • the end section 25 arrives after the locking bolt 22 has been closed due to the driving rod, the end section 25 extending within an entry space 28 of the striking plate 26 and being supported there.
  • this will be discussed in detail later.
  • the locking bolt 22 continues in a locking tail 29.
  • a longitudinal slot 30 which runs parallel to the cuff 2, that is to say transversely to the bolt displacement direction, for the entry of a driving pin 31 of an engagement arm 32 of the nut 16.
  • the nut 16 is then equipped with an actuating arm 33.
  • an edge-side recess 34 for the entry of a coupling pin 35.
  • the edge-side recess 34 has two edge edges 36, 37 which are at an angle of approximately 80 ° to one another, the apex enclosed by them being rounded runs and is adapted to the radius of the coupling pin 35.
  • U-shaped connecting rod connecting slide 38 is coupled to the connecting rod 8. Its U-web 43 slides on the inside of the lock case rear wall 12 of the additional lock 9. In the retracted position of the locking bolt 22, one U leg 39 extends near the lower lock case side wall 14, see FIG. 5. The opposite U leg 40 forms a stop 41 pointing in the direction of the locking bolt 22 for cooperation with a counter shoulder 42 on the locking tail 29 of the locking bolt 22.
  • the connecting rod connecting slide 38 is provided in the area of its web 43 with a groove 44 in which the actuating arm 33 and the adjoining area of the engagement arm 32 are guided on both sides.
  • the connecting rod connecting slide 38 is equipped with a slightly curved transverse slot 45, into which the coupling pin 35 projects.
  • the coupling pin 35 In the closed position of the locking bolt 22, the coupling pin 35 is located at the end of the transverse slot 45 facing the cuff 2. Furthermore, the coupling pin 35 is completely immersed in the recess 34 on the edge. 5 that the edge 36 of the recess projects into the transverse slot 45 by a small amount.
  • the coupling pin 35 is moved into this end position by the one spring leg 46 a torsion spring 47 fixed on the connecting rod connecting slide 38 is pushed in.
  • the other spring leg 48 is supported on a cross pin 49 of the connecting rod connecting slide 38th
  • the coupling pin 35 is each equipped with a stepped guide pin 35 ', which guide pin 35' plunge into a link guide 50 in the lock base 11 and lock cover 15 of the additional lock 9.
  • the link guide 50 is designed in a closed curve shape, which surrounds a central extension 51 of the castle floor and the castle ceiling.
  • the actuating arm 33 is pivoted, which with its Edge 37 abuts the coupling pin 35 and moves it against the force of the torsion spring 47 in the direction of the other end of the transverse slot 45 of the connecting rod connecting slide 38, see FIG. 11.
  • the coupling pin 35 leaves the recess 34 and reaches the area of end edge 52 of the actuating arm 33 adjoining the edge 37.
  • the guide pins 35 ′ of the coupling pin 35 are located in the area b of the link guide 50, specifically in the area of the rear guide path 53 of the link guide 50.
  • the locking bolt 22 can be closed by rotating the handle 19 in the opposite direction.
  • the actuating arm 33 is pivoted, the edge-side recess 34 coming in opposite position to the coupling pin 35, which is pressed into the recess 34 due to its spring action.
  • the locking bolt 22 is withdrawn from the nut engagement arm 32. The starting position according to FIGS. 1 and 5 is then again present.
  • the locking bolt 22 can, however, also be locked via the central lock 3, by means of the key associated with the locking cylinder 7.
  • On the first closing tour only the drive rod 8 shifts in the upward direction, while the main bolt 6 does not change its closed position.
  • the locking bolt 22 reaches the position shown in dash-dotted lines in FIG. 5. The locking bolt 22 is thus shortly before the locking bracket catch position such that the constriction 24 on the locking bolt side is in the rebate air and the cross-sectionally larger end section 25 is in the locking bracket 27.
  • a one-way clutch is realized between the connecting rod connecting slide 38 and the actuating arm 33 which is coupled in a rotationally fixed manner to the handle 19.
  • the locking pin drive can be uncoupled from the drive rod movement in a handle-operated manner.
  • the locking bolt 22 can be brought into a locking bracket catch position by means of the handle. After the drive rod has been locked, the locking bolt 22 is coupled to the drive rod return movement in order to withdraw it.
