Abstract

A slider activated door lock has a spring loaded latch (5) which is pulled back by a slider (18) operated by the lock and by a retracting lever (36) which is operated by the door operating handle. The retracting lever has a pivot axis (35) behind that (10) of the door handle. The retracting lever is mounted in an extension to the top of the lock housing and has an extension arm (39) contacted by a cam (9) on the door handle mounting.

Description

The invention relates to an espagnolette lock a trap which can be withdrawn by pressing the trigger and with bolt that can be moved by locking cylinder actuation and drive rod connecting slide and with one can be swiveled onto the connecting rod slide by pushing the trigger acting, angular retraction lever to retract the connecting rod connecting slide and of the bar.

A castle of the type in question is known from EP 0 834 633 A1, the trap tail in two parts is designed. The front part of the trap tail carries the trap head while the rear part over a pivot pin is coupled to the retraction lever. Then the nut arm of the rear part engages Trigger nut. In this version, the Swivel axis for the retraction lever between the latch head and nut, so that particularly small backset cannot be realized are.

The invention has for its object a generic Espagnolette lock with simple construction To be designed so that particularly small backset can be achieved are.

This task is first and foremost an espagnolette lock with the features of the claim 1 solved, it being based on the fact that the Swivel axis of the retraction lever rear of the nut is arranged.

As a result of such a design is an espagnolette lock of the kind of simple structure in question realized. The trap tail can now as a result of rear of the nut-mounted retraction lever in one piece be designed. This is accompanied by a reduction in Backset to 35 µm and smaller possible. Accordingly the espagnolette lock also the cheapest tubular frame doors be assigned. However, there are no disadvantages with regard to the panic function, i.e. the pre-closed one Bolt, and the upstream connecting rod connecting slide the trap from the inside of the door withdraw using the pusher. The in itself proven design of a generic drive rod lock can largely be maintained since the Housing cover and housing base one above the nut axis form lying bulge in which a Retraction lever bearing housing extension is arranged. The bulge is such that the extension with the rear edge of the lock housing is aligned, so that with regard to the installation depth no disadvantages arise. in the In detail there is such a design that a Drive arm of the retraction lever can be acted upon by a nut arm is. The nut arm thus acts directly the retraction lever, which is a cheap force attack the connecting rod slide by means of the retraction lever allows. It is also provided that the drive arm in the locking cylinder-operated bolt lock in the Path of movement of the nut arm swivels. In a panic situation accordingly takes place along with the lever shift taking the retraction lever with you immediately instead, which in turn on the connecting rod connecting slide acts. Contributes to a shallow installation depth then at that the drive arm in pre-locked Bolt position partially overlaps the latch tail. Then the configuration according to the invention allows Realization of an espagnolette lock with split Nut. The correspondingly split nut has an inner and outer nut half, the outer Half of the nut only acts on the trap tail and into the inner half of the nut both latch and retraction lever operated. The required unilateral clearance between the two nut halves is easier in. wise created in that the associated with the inner nut half Nut arm assigned to the outer half of the nut Carries the nut arm as it pivots. Farther it is provided according to the invention that the angular Retraction lever is crescent-shaped and with its Sickle cavity in his caused by the trigger groove Appropriate position of the drive rod lock Position on a sleeve of a fitting screw opening is present. This causes the retraction lever to experience a support. Another beneficial one Characteristic is the fact that the output arm in its the open position of the espagnolette lock corresponding position with the trap withdrawn Trap tail partially overlapped. So it finds one Nesting instead of building a crowded castle furniture. Finally is still to emphasize that the output arm in a recess a vertical section of the connecting rod connecting slide intervenes. This intervention is neither with the latch still closed and the latch withdrawn abandoned, so that always the correct shooting function is guaranteed.

The espagnolette shown has a a faceplate 1 connected lock housing 2. Back leads on the faceplate 1 an upper and lower from the Lock housing 2 emerging drive rod 3 or 4. The latter are with latch members not illustrated provided in a known manner with frame-side Interact locking parts.

In the upper area of the lock housing 2 there is a trap 5 guided. The trap head 6 is with a trap tail 7 connected. At the end, this forms a driving lead 8 off to attack a nut arm 9 a trigger nut 10. According to that illustrated in Figures 1-5 Embodiment, the follower 10 is in one piece designed. The follower 10 is with another Nut arm 11 equipped, which has a parallel to the Forend 1 extending spring slide 12 counterclockwise is applied. The spring slide 12 is under the action of a compression spring 13. Die Nut 10 including spring slide 12 and compression spring 13 can be installed in the espagnolette lock Nut bearing housing 14 added. The latter includes also an unillustrated attack, which as a limit stop for the nut 10 in their Home position serves.

To advance the case 5 serves as a torsion spring designed latch spring 15, which from a lock housing side Stud 16 is worn. The advance movement the case 5 is limited in size. Your trap head 5 passes through a shape-adapted opening 17 of the cuff 1.

Below the trap 5 is a bolt in the lock housing 2 18 guided, the bolt head 18 'a cross-section adapted Opening 19 of the cuff 1 penetrates.

The castle floor 20 and the one arranged parallel to it Castle cover 21 carry a support plate between them T. This is stored in one of the lower areas Lock cover 21 facing bore 22 a ring gear 23. A locking cylinder insertion opening 24 crosses this hole. The axis of rotation of the not illustrated Cylinder core is eccentric to the axis of rotation of the Sprocket 23, below it.

The ring gear 23 has a radially directed slot for a dash-dotted line Locking member 26 of a profile lock cylinder, not shown. This is called a freewheel cylinder designed with freely rotatable when the key is removed Locking element 26. When the key is inserted, the locking element is however coupled to the cylinder core.

Comb two with the external toothing of the ring gear 23 Output gears 27, 28 of a reduction gear G. Its end wheel 29 meshes with a parallel to the faceplate 1 guided rack 30 of a drive rod connecting slide 31, which is in the upper area of the lock housing 2 is guided and the upper drive rod 3 carries.

In parallel opposite to the rack 30 is one further rack 32 guided, which parallel to the aforementioned rack 30 extends. The rack 32 is part of a further connecting rod connecting slide 33, which in the lower area of the Lock housing 2 is guided and the lower drive rod 4 carries. In this way, by the end wheel 29 of the Reduction gear G the connecting rod connecting slide 31, 33 driven in opposite directions and thus the drive rods 3, 4.

The drive rod connecting slide 31 controls with the interposition a pivot lever 34 the bolt exclusion in such a way that first the connecting rod slide 31 precedes the bolt exclusion and then the bolt 18 is taken along. Hereby can first lock bars in the drive rod side Kick attack and pull the door, so that then the latch 21 in the him assigned retraction plate can retract. This is known from EP 0 834 633 A1, so that this is not discussed in more detail. This is also true towards the change-over actuator, with the lower connecting rod connecting slide one not illustrated Change lever applied, which in turn the Trap 5 pulls inside the lock.

There is a nut 10 above and to the rear Swivel axis 35 for an angular retraction lever 36 for retracting the upper connecting rod connecting slide 31 and thus via the end wheel 29 of the lower connecting rod connecting slide, what the withdrawal movement of the pre-closed bar 18 causes.

The pivot axis 35 is formed by a housing extension 37, for which the housing base 20 and the housing cover an aligned one above the nut axis Form lying bulge 38, cf. in particular Fig. 5. The down and towards the nut 10th facing drive arm 39 of the retraction lever is positioned that it can be acted upon by the nut arm 9. When locking the bar, cf. Fig. 2, the drive arm 39 pivoted into the path of movement of the nut arm 9, cf. Fig. 2. Overlapped in this pre-locked latch position the drive arm 39 partially the bolt tail 7 or its lead projection 8. The angular Retraction lever 36 is curved approximately sickle-shaped. The sickle cavity formed by the output arm 41 42 is in the open position caused by the follower 10 the drive rod closure on a sleeve 43 a fitting screw passage opening 44, cf. Fig. 4. The sleeve 43 is also part of the Housing extension 37. Fig. 4 also shows that the output arm 41 in its the open position of the Espagnolette lock corresponding position retracted trap 5 partially the trap tail 7 overlaps. To attack the output arm 41 forms a upper vertical section of the connecting rod connecting slide 31 a recess 40 in which the free end of the drive arm 41 is immersed.

The espagnolette lock designed in this way allows it to Realize backset, which is the same or smaller than 35 mm.

The following mode of action occurs:

Is that with the espagnolette lock designed according to the invention equipped door closed, so located only the trap 5 in the engaged position to a counter locking part on the door frame side. Of the outside of the door can be activated by the lock cylinder the latch 5 withdrawn via the closing member 26 become. With the corresponding closing rotation, this takes Locking member 26 the ring gear 23 in the clockwise direction With. Via the end wheel 29 of the reduction gear G the connecting rod connecting slide 33 experiences an upward displacement, whereby he did not illustrate the Exchange lever pivoted and the trap 5 in known manner in the castle inward direction. A Torsion spring 45 arranged on the lock housing side is used here over the upper end of the connecting rod connecting slide 33 curious which torsion spring 45 after key actuation the connecting rod slide 33 in his Starting position returns.

The retraction of the latch 5 from the inside of the door is by means of a door handle illustrated with a dot-dash line 46 possible. With its downward shift is the latch 5 in the inward direction via the nut arm 9 pulled, against the force of the trap spring 15.

The locking of the bolt 18 with the door closed requires a closing rotation of the closing member 26 counter clockwise. About the ring gear 23 and the reduction gear G are the connecting rod connecting slide 31, 33 moved in opposite directions, namely the upper connecting rod connecting slide 31 upwards and the other connecting rod slide 33 down. To a certain displacement of the connecting rod connecting slide 31 is on the rack 30 of the pivot lever 34 pivots, resulting in an exclusionary movement of the bolt 18 leads, in the position according to Fig. 2. As a result of the recess 40 of the upper connecting rod connecting slide 31 the retraction lever 36 so pivoted that the drive arm 39 then the driving projection 8 of the trap tail 7 overlaps and immediately is close to the nut arm 9.

Starting from the locked position of the bolt 18 it is possible from the inside of the door, the espagnolette lock without key actuation - with realization a panic function - to open. This is to depress the door handle 46 and thus the handle follower 10 to pivot. The nut arm 9 acts on the Driving projection 8 of the trap tail 7 connected so that the latch 5 is pulled in the direction of the lock becomes. Along with this, the nut arm 9 also acts the drive arm 39 of the retraction lever 36, which in the Recess 40 engaging output arm 41 the connecting rod connecting slide 31 moved in the downward direction. Be on the end gear 29 of the reduction gear G. the other gears of the reduction gear G rotated and thus also the driven gears 27, 28, which rotate the ring gear 23. This is possible because the corresponding profile lock cylinder as a freewheel cylinder which is designed with the key removed the rotatability of the closing member 26 relative to the locked cylinder core allows. Both on the end wheel 29 oppositely moving connecting rod connecting slide 31, 33 drive through an intermediate position 3 in the position shown in FIG. 4, in which all bolt links including case 5 die Take the return position. The door can thus be opened. If the door handle 46 is then released, the trap 5 returns to its leading position. Furthermore, the follower is by the spring slide 12 10 rotated back to its original position.

In the second illustrated in Figures 6 to 9 Embodiment carry the same components the same Reference numbers. The follower nut 47 is now divided into two such that the division plane parallel to the castle ceiling and castle floor runs. In detail, the Handle nut 47 from an inner nut half 48 and one outer nut half 49 together. Both nut halves 48, 49 are each equipped with a nut arm 50 to attack the Spring slide 12. The outer nut half 49 then points another nut arm 51, which outside the Path of movement of the drive arm 39 in another Plane runs and only on the tail tail 7 or whose entrainment projection 8 acts. The inner half of the nut 48, however, forms a nut arm 52, which both Trap 5 and the retraction lever 36 actuated. For this the nut arm associated with the inner nut half 48 drags 52 when pivoting that of the outer nut half 49 assigned nut arm 51 under the implementation of a unilateral passage with.

The mode of operation of this second embodiment corresponds largely that of the first embodiment. The outer nut half 49 now also carries an operating handle. With it, however, only the trap 5 withdrawn, cf. Fig. 7.

When shifting the inner nut half 48 by means of On the inside, the nut arm 52 acts on the drive arm 39 of the retraction lever 36 and transferred via the Output arm 41 the connecting rod connecting slide 31 in his open position. The bolt is closed at the same time. Furthermore, the nut arm 52 acts on the Nut arm 51 of the outer nut half 49, which nut arm 51st the latch 5 pulls inside the lock, cf. Fig. 8.

According to this second embodiment, the inner one Nut half 48 in the area of the handle mandrel opening a protruding collar 53, which fits the shape in a bearing cavity 54 of the outer nut half 49 lies, cf. Fig. 9. Obtained in this way both nut halves 48, 49 improved guidance.

The third illustrated in Figures 10-13 Embodiment is similar to that described above. Also here again it is true that the same components are the same Wear reference numbers. The follower nut 47 'is also divided into two, consisting of the outer nut half 48 ' and the inner nut half 49 '. The latter is with one inside protruding collar 53 ', which into a bearing cavity 54 'of the outer nut half 48' immersed. The mode of action corresponds to the previous one. When the outside door handle is moved, the outer nut half 48 'into the position according to FIG. 11 pivoted, the one nut arm 52 'of the trap 5 pulls inside the lock and its other nut arm 50 'den Spring slide 12 relocated. The inner half of the nut 49 ' stands still.

If the door handle according to FIG. 12 is actuated, then he pivots the inside of the nut half 49 ', which the outer half of the nut 89 'via its nut arm 51' due to the one-sided clearance. The outer Nut half 48 'pulls the trap 5 over its nut arm 52' back with the nut arm 52 'also on the retraction lever 36 acts.

All disclosed features of this application are essential to the invention. In the disclosure of the application will hereby also the disclosure content of the associated / attached Priority documents (copy of pre-registration) fully included, also for the purpose Features of these documents in claims of this Register now.
