Espagnolette locking device

p0001The invention relates to a drive rod lock, consisting of a central lock with guided from this emerging and back a cuff drive rod which can be moved from an open position into a blocking position upon actuation of the central lock, said actuator is associated with a bolt throw-movement and with a with driving rod interacting, an additional lock bolt having auxiliary lock.

p0002A drive rod lock of the type in question is known from DE 34 16 148 A1. There upon actuation of the central lock in the locked position an auxiliary lock for leading drive rod is displaced. This is coupled to a driving rod connecting slide which. Via a pin / slot controlling a coupled with the addition deadbolt transmission pivot lever shifted along with a preclose the auxiliary lock bolt In the locked position of the center cam therefore takes next to the release thereof and the additional deadbolt locking position. The operation of the central lock in the open position of this locking position out takes place in reverse order, wherein both latches are controlled schloßeinwärts and left frame side Schließblechausnehmungen.

p0003The object of the invention is an object to increase the security against burglary in a generic Espagnolette in manufacturing technically simple manner.

p0004This technical problem is solved first and substantially at a Espagnolette with the features of claim 1, it being provided that the of a the auxiliary lock allocated locking cylinder vorschließbare additional deadbolt only in the locking position is completely vorschließbar and the driving rod displacement locks.

p0005In consequence of such embodiment there is provided a drive rod lock of the type in question of increased security against burglary. The central lock can now be remotely controlled from the locked auxiliary lock. The closing sequence of the espagnolette-lock is mandatorily required. Only the operation of the central lock of the open position into the blocking position must be einnergehend a preclose the bar of the central lock with simultaneous displacement of the drive rod. Only then can be easily included into its blocking position by means of the auxiliary lock allocated locking cylinder of the auxiliary lock bolt. Another function satisfies the auxiliary lock bolt by simultaneously shutting off the driving rod displacement. It is therefore not possible to actuate the central lock, since the drive rod, it can not move. It must be moved back until the auxiliary lock bolt from the associated lock cylinder into the release position with the simultaneous release of the operating rod. Then only the operation of the central lock can be undertaken, on the one hand the drive rod and the other part of the latch of the center cam be moved into the open position. In this, however, it is not possible to transfer by means of the auxiliary lock associated with the lock cylinder the auxiliary lock bolt in the forward position, since this is prevented by the drive rod. Therefore, the user knows at a closing operation of the auxiliary lock, whether the central lock is in the open or in the locking position. In an attempt to break it is not enough to overcome only the lock cylinder of the central castle, and subsequent closing operation is not possible through the locked by the auxiliary lock espagnolette.

p0006An advantageous development of the invention to provide a run in overlapping for additional deadbolt driving rod connecting slide provided with a remote in his cuff edge located locking recess for admission of a bolt side blocking pin. It is only necessary to form the blocking pin the extra deadbolt and equip the driving rod connecting slide with a locking recess. If a forward displacement of the auxiliary lock bolt in the open position captivating central lock, the locking pin abuts the cuff facing away from edge of the driving rod connecting slide and is unable to enter the locking recess, thus can not perform the closing operation of the auxiliary lock bolt. The design measures on the driving rod connecting slide and the additional deadbolt are low associated with a low-cost manufacturing of the espagnolette-lock. The preclose the auxiliary lock bolt is only possible by excavating an associated therewith tumbler. It is advisable to arrange the tumbler on the extra deadbolt itself, so that the tumbler mitverlagert during the closing process of the auxiliary lock bolt.

p0007An embodiment of the invention with reference to the drawings will be explained. It shows:<dl id="dl0001"><dt>Fig. 1</dt><dd>a view of an inventively designed espagnolette-lock,</dd><dt>FIG. 2</dt><dd>klappfigürliche the illustration of FIG. 1,</dd><dt>Fig. 3</dt><dd>in individual representation a view of the auxiliary lock with removed lock cover, on the open position of the espagnolette-lock,</dd><dt>Fig. 4</dt><dd>one corresponding to FIG. 3 illustration, where instead of respect to this, the central lock, the locking position occupies connected impacted operating rod and wherein the auxiliary lock bolt is pre-connected at the same time blocking the driving rod displacement and</dd><dt>Fig. 5</dt><dd>the section on the line VV in Fig. 4.</dd></dl>

p0008The designated with the number 1 as a whole has a Espagnolette türfalzseitig be determined Cuff 2. Here are a central lock 3 and above an auxiliary lock 4 set. It can also be adjacent to above the auxiliary lock 4 an unrepresented pin bolt lock. Also can be provided below the central castle such a pin bolt lock.

p0009The central lock has a cuff 2 thoroughgoing case 5 and including a latch 6. To retract the trap 5 is mounted in a central lock nut 3 7. In an appropriate distance below the same the central lock 3 takes a lock cylinder 8. By the same may be the latch 6 back and forth close and withdraw the case 5 via alternate action. The central lock 3 is a known per se, unillustrated reduction gear incorporated, by means of which an out emerging from the central lock 3 drive rod 17 is displaced. This leads to the auxiliary lock. 4

p0010The auxiliary lock 3 has a lock bottom 10, which is set appropriately on the cuff. 2 Surface mounted on the lock bottom 10 adjacent in the longitudinal direction of the forend cuff 2, a driving rod connecting slide 11 out. To go from its guide driving rod connecting slide 11 from superposed pins 12, 13 which engage in vertically disposed longitudinal slots 14 and 15 of the lock base fourteenth In the thickened designed end portions 11 'of the driving rod connecting slide 11, a respective provided at right angles to the faceplate 2 aligned to the cuff plate 2 open towards the transverse slot 16, in which the angled end 17' of the connecting rod 17 engages. Covered the drive rod 17 of the cuff 2 is such that the inner surface of the cuff 2 lists the outer surface of the drive rod 17th

p0011In the transverse center of the auxiliary lock 4 an additional bolt 18 is guided above the driving rod connecting slide 11th Meanwhile bolt head 18 'passes through a cross-section adapted recess 19 of the cuff 2, while the bolt tail 18' 'with a pin protrusion 20 engages in a transverse slot for Cuff leadership 21st

p0012On the opposite the bolt head 18 'stepped stepped bolt tail 18' '22 is guided a vertically rising tumbler. For guiding serve two from the bolt tail 18 '' outgoing shaft portions 23, 24 which extend through a respective longitudinal slot 25 or 26 of the tumbler 22nd The longitudinal slot 25 receives a compression spring 27 which load the tumbler 22 in the downward direction. Limited is the downward movement by reaching to the lock bottom 10 Tour projection 28, which 'rests on the upper edge 18' of the bolt tail 18 '. The tour projection 28 cooperates with a closed bottom locking shoulder 29. In its downward displaced position, the lower end of the tumbler 22 is in registration to a Schließeingriffsausnehmung 30 of the bolt tail 18 '', which Schließeingriffsausnehmung 30 extending from the lower edge of the bolt tail.

p0013Then carries the bolt tail 18 '' still a reaching to the base of the lock 10 locking pins 31. This cooperates with a locking recess 32 of the driving rod connecting slide 11, which locking recess 32 at the cuff facing away from edge 11 'is the driving rod connecting slide 11, and While approximately at the middle of the driving rod connecting slide eleventh

p0014It provides the following operation of a: In the open position of the central lock 3 which latch 6 is withdrawn. Further, the drive rod 17 takes a removable from FIG. 3, a position and therefore also the driving rod connecting slide 11 such that the locking recess 32 is located outside the path of movement of the blocking pin 31 of the auxiliary lock latch 18. If now been joined by a the auxiliary lock 4 allocated locking cylinder 33 via the closing member 34 of the auxiliary lock bolt 18 so abuts the blocking pin 31 against the facing edge 11 '' of the driving rod connecting slide connected with the fact that the complete closing process can not be run. In this closing movement, the tumbler was the closing member 22 against spring force dug such that then the tour protrusion 28 extends above the locking projection 29th Further, the closure member 34 is entered into the Schließeingriffsausnehmung 30th

p0015The preclose the auxiliary lock latch 18 thus requires first the operation of the central lock 3 from the open position into the locking position. In this case, excludes the bolt 6 of the central lock 3, while the driving rod 17 is displaced in the downward direction. She takes the driving rod connecting slide 11 of the auxiliary lock 4, so that after a successful closing of the central lock is present the position of FIG. 4. Then the locking recess 32 of the driving rod connecting slide 11 extends at the level of the path of movement of the blocking pin 31 of the auxiliary lock bolt 18, so that by means of the lock cylinder 33 on the closure member 34 of the auxiliary lock bolt 18 into the position shown in FIG. 4 can be moved. Here, the tour projection 28 moves from one to the other side of the lock projection 29 and thus blocked the rearward displacement of the auxiliary lock bolt 18. The full preclose the auxiliary lock bolt 18 is possible because the Bl ockierungszapfen 31 of the auxiliary lock bolt 18 in the locking recess 32 of the driving rod connecting slide 11 can engage. Thus, the driving rod displacement is blocked, corresponding to an externally controlled blocking of the central lock. 3 By means of the local lock cylinder 8 the latch 6 can not draw conclusions. Also, no displacement of the drive rod 17 is possible.

p0016The central lock therefore requires first a back closing the auxiliary lock bolt 18 from the pre-locked in the back closed position according to FIG. 3 with a simultaneous release of the locking recess 32 of the driving rod connecting slide 11. Only after the operation of the central lock 3 can perform under retraction of the bolt 6 and upward displacement of the drive rod 17, so that then again the position according to FIG. 3 of the auxiliary lock 4 is present.
