Espagnolet.

The invention relates to a drive rod lock according to the preamble of claim 1.

A drive rod lock of the type in question is known from European Patent 0,041,913, which is relative to the operating arm of the nut is a gear that is engaged with the counter toothing of the applied by the compression spring in its end position the slide. The application is carried out via a longitudinally guided in slots of the lock housing slide, on which the supporting one end of the compression spring. The other end of the compression spring support on the other hand takes place on a further, likewise longitudinally movable in slots of the lock housing second carriage. a series arrangement in an alignment of these aforementioned components is therefore provided, which on the one hand requires a larger installation space inside the lock housing and on the other hand requires a higher accuracy of parts. Such prescribed Rückholvorichtungen not suitable for espagnolette locks, which have both low and extended backsets.

The object of the invention is therefore the object of a generic rod lock in manufacturing technically simple manner in such a way that the nut-making in its basic center position components are spatially low accommodated with sufficient spring force.

In consequence of such design is created by an increased use value a rod lock of the type in question. The the nut holding in its basic center position components can be accommodated spatially low. The inventive design allows it to assemble these components together with the nut as external mounting unit in order to then be installed in the lock housing, coupled with lower production costs of the espagnolette lock. It also allows this assembly unit also to manufacture espagnolette locks that have a low or an extended backset. By the compression spring are held together via the coupling pin of the operating arm, the slide and auxiliary slide to form an assembly such that the claw-shaped end of the actuating arm is clamped between the end face of the slider and the coupling pin. If a pivotal displacement of the actuator arm in one direction, so is therefore taken over the kingpin of the auxiliary slide against the force of the compression spring. A shifting of the actuator arm in the other direction, however, leads to an immediate action on the slider by the claw-shaped end accompanied by a compression of the compression spring of the other side. This means that the operating arm is loaded either on the train or in print. The claw-like gripping under the coupling pin also leads to mounting technical advantages. The joining of the auxiliary slide, slide and actuating with compressed spring into a single unit is favored by the outgoing from the auxiliary pusher mandrel which space-saving passes through both the spring and the slide and with his bügelförmi gen finish covers the pin. Characterized in that the slide receives a part section of the pressure spring, this undergoes a stabilization against buckling. Also it is then protected an inside of the corresponding unit. Thus, the coupling pin is in a shift of the operating arm not mitverlagert he will stop at one end of the arc-shaped slot of the lock housing. Then, the claw-shaped end pushes the slide and displaces the latter against the force of the compression spring. If the pivoting movement of the actuator arm in the other direction, a displacement of the slide is determined by the abutment of the edge of the slot block opposite mating stop edge. A variant is characterized by a two-armed design of the actuator arm. One arm forms the claw-shaped end and the second arm of the lever, to which the coupled with the nut link plate engages. From the foregoing it can be seen that the prefabricated assembly unit constructional conditions can be largely adapted such that an arrangement of this mounting unit in the lock housing can be made at any angle. Furthermore, the adjustment of the length of the mandrel assembly brings technical advantages. Accompanied by an adjustment of the length of the mandrel will also change the bias of the compression spring. The adjustment of the mandrel length can for example be done by threaded adjustment. The attacking on the auxiliary spool end of the mandrel is then provided with an external thread and the auxiliary slide with an internal thread. After assembly of the coupling pin, actuator, valves and queuing the compression spring then only needs to be screwed to the auxiliary slide, which allows the setting of the compression spring on the appropriate voltage in a simple manner. Hence a driving rod displacement can be performed by shifting of the actuator arm or the nut, it engages in a toothed segment, with the interposition of a respective one-sided no-load stroke to a tooth strip section of the drive rod. If the toothed segment associated with the actuator, the unilateral clearance allows a shift of the nut for the purpose of withdrawal of the case, without entrainment of the tooth bar portion of the drive rod. The displacement of the actuating arm in the other direction, then leads to an entrainment of the tooth segment and the tooth bar portion, according to which displacement of the actuator arm and thus According to the nut returns to the idle stroke in its basic center position. Further, it is possible that the nut itself forms the operating arm, that is of uniform material with that is designed. Then, an assembly unit is also be prefabricated, which consists of a particularly small number of components. On one hand, the nut is used to shift the case. On the other hand it controls the gear segment which serves for displacement of the toothed ledge portion of the drive rod. When the sector gear still meshes with a further toothed segment, espagnolette locks can be provided with opposite movable rods. The same gear segment with the previously described reset device can then be used. In the one case, then the gearing irrelevant.

The in Figs. 1 - rod lock represented 14 of the first embodiment has a face plate 1, to which in a right angle position a lock bottom 2 is fixed. In a parallel arrangement to this extends a tethered by means of screws 3 lock cover 4, which engage screws into bottom-side closed studs. 5

In the upper part of the lock housing stored in lock bottom and lock cover 2 4 6 a nut for receiving a direction indicated in Fig. 1 dash-dot pusher 7. If this its horizontal position I a, this corresponds to the basic center position. The direction indicated by the line II position is one in which the nut 6 withdraws a case. 8 The latter is composed of a head case 8 'and a catch tail 8˝. The drophead 8 leads in the face plate 1, while the case is 8˝ tail out closed base side. At the catch tail 8˝ engages a leg spring 9 which 8 charged the case in the outward direction. The loading of the latch tail 8˝ made by a Nußarm 10 of the nut 6. equipped Otherwise, the nut 6 with a emanating from the Nußarm 10 rotation stop 11, which interacts with a stop edge 12, 13 an arc-shaped opening 14 of the lock cover 4, so that the handle positions II and III thus learn a stop limit.

In a right angle position to Fallenbetätigungsarm 10 comes from the nut 6, a further arm 15 from. There engages by means of a pivot pin 16 to a link plate 17 which is in turn coupled via a hinge axis 18 to the second arm 19 of a Betätigunsarmes 20th The latter superimposed below the nut 6 to einen.schloßgehäuseseitigen articulation pivot 21. The second arm 19 gegenüberlie lowing first arm 22 forms a claw-shaped end 23 of which engages beneath a run in an arcuate slot 24 of lock bottom 2 and lock cover 4 kingpin 25th At the height of the claw-shaped end 23 of the coupling pin 25 is comprised of a bracket 26, which continues in a downward, approximately parallel to the face plate 1 extending mandrel 27th An end forming the latter from a threaded portion 28th This engages in an internal thread of a peg-shaped centering projection 29 a of the auxiliary slider 30th An outgoing of this guide projection 31 projects into an approximately vertical longitudinal slot 32 of the lock base 2. Opposite the guide protrusion 31 is located on the auxiliary slider 30 has a groove 33, in which a einwärtsgedrückte rib 34 of Schloßdekke 4 dips. This rib 34 extends parallel to the orientation of the longitudinal slot 32, whereby the auxiliary slider receives an exact guidance. The upper end of the longitudinal slot 32 forms a counter-stop edge 35, which faces by far the stop edge 36 of the arcuate slot 24th Against this stop edge 36 of the coupling pin 25 is pulled by an auxiliary slide 30 stressful downward pressure spring 37, the latter being the centering surrounds 29 and hence the mandrel 27 accommodates.

The mandrel 27 extends through a slide 38. From the upper end of this is a projecting into the longitudinal slot 32 of projection 39. That the lock cover 4 facing, lower end of the slide 38 is also provided with a groove 40, in which the rib 34 is immersed. The slider 38 receives only a section of the compression spring 37 and has an axis extending at the height of the protrusion 39 support surface 41 for facing the end of the compression spring 37. In consequence of these foregoing configuration, the claw-shaped end 23 of the operating arm 22 between the upper face 42 of the slider 38 and the coupling pin 25 is clamped so that actuating arm 20, mandrel 27, auxiliary slide 30, compression spring 37 and slide 38 form a cohesive unit that can be inserted as a whole into the lock. Optionally, to this unit are still the joint plate 17 and the nut 6, so as to obtain a coherent, easy to install chain. This configuration makes it possible to arrange a cohesive unit in a different orientation within the lock housing of a drive rod lock. There are merely provide the guide slots in the appropriate location.

Another component of the castle is arranged below the above assembly bolt 43, which is associated with a 44 sprung downward tumbler. The bolt 43 extends through a lower drive rod 45 of the drive rod lock. This drive rod 45 runs inside the face plate 1 and is provided at the level of the operating arm 20 with a toothed ledge portion 46th Following this the driving rod 45 is in positive connection with a driving rod connecting piece 47, of which an upper drive rod 48 emanates. Both rods 45, 48 carry the locking elements in the form of locking cams 49, which in turn are guided in the longitudinal slots 50 of the faceplate. Are the locking pin 49 at the upper end of the longitudinal slots 50, so this corresponds to the open position of the espagnolette lock.

To displace the driving rods 51. is a also on the hinge pivot 21 rotatably mounted toothed segment This is designed with two arms. One arm forms the toothing 52, which engages with the tooth strip section 46. Both arms of the toothed segment 51 are diametrically opposed arc slots 53, 54 provided. In the arc slit 53, the hinge axis 18 between the link plate 17 and the second arm 19 plunges. In the open position of the espagnolette lock the hinge axis 18 extends at the upper end of the arc slit 53. The other arc slot 54 on the other hand is penetrated by the coupling pin 25, located in this position at the lower end of the arc slit 54th Accordingly, an idle stroke between operating arm 20 and toothed segment 51 is created.

The operation of the drive rod lock is as follows: Starting from the open position of the espagnolette lock, the latch 43 are closed by means of a pre-inserted into the rod lock lock cylinder 55th In the key operation, the tumbler 44 is raised to the position shown in FIG. 5 by the closing member 56, the then the displacement of the bar in the position shown in FIG. 6 permits. It should be noted that the rods or their closing pin 49 have not yet taken the locking position. In this pre-locked position of the bolt 43, a locking pin 57 sets against a projection 58 of the lower drive rod 45 and blocks against downward displacement, see Fig. 6.

If the rods are brought into the locking position shown in FIG. 7, then, starting from the position shown in FIG. 3 the lever 7 to pivot into the position of III. In this operation, the nut 6 11. About engages the coupled with their parts in the position shown in Fig., The link plate 17 and actuator arm 20, the sector gear 51 is dragged immediately, which the drive rod 45 and the driving rod connecting piece 47 and the other drive rod 48 shifted in the downward direction and thus also their closing pin 49. This pivoting movement is limited by the stop edge 13 of the lock cover 4, against which the rotation stop 11 of the nut 6 abuts. By pivoting the operating arm 20 whose claw-shaped end 23 acts on the end face 42 of the slide 38, which moves in the downward direction against the force of compression spring 37, also see FIG. 14. The coupling pin 25, on which the mandrel 27 and thus the auxiliary slide 30 support, remain in their position. Then, when the lever 7 is released, the slider returns 38 spring-loaded strike in its initial position under the pivoting of the actuating arm 20, which the nut 6 and thus the handle returns via the link plate 17 in the base-center position. According to the arcuate slots 53, 54 remains the sector gear 51 are provided, so that then the articulated axle 18 and the coupling pin 25 the opposite ends of the arcuate slots 53, 54 adjacent. In this locking position of the connecting rods of the latch 43 is vorschließbar. Fig. 8 shows the raised during the closing stroke position of the tumbler 44, which allows more preclose of the bar 43, in the position of FIG. 9, in which the locking pin 57 is located above the projection 58 of the connecting rod 45 and thus the return movement blocked. Opening the drive rod lock therefore initially demanded the return closing of the bolt 43. Anschießend the handle 7 to move into the position II, the castle Taken lessons reached 10 and 13 GE in the position shown in FIG.. By means of the nut is withdrawn the case. 8 Furthermore, the link plate 17 pivots the operating arm 20, thereby moves in the upward direction over the mandrel 27 of the auxiliary slider 30 against the force of the compression spring 37th The slider 38 is in turn supported on the counter-stop edge 35 of the longitudinal slot 32, also compare Fig. 13. During this operation, the sector gear 51 is also carried along. It remains in its end position. The arcuate slots 53, 54 allow then under the action of compression spring 37 return pivoting of the actuating arm 20 and the nut 6 to the initial position of FIG. 3.

From the position of FIG. 3 may occur at any time a Nußverlagerung for withdrawing the case. Here, is displaced over the actuating arm 20 of the slide 38 against the force of the compression spring 37th According to the idle stroke the toothed segment is not taken. Then, the spring brings 37 the aforementioned components to their normal position.

The on the threaded section 28 of the mandrel 27 can be screwed auxiliary slider 30 allows the rest of an adjustment of the length of the mandrel and thus a corresponding adjustment of the biasing force of the compression spring 37th

According to the second embodiment shown in Figs. 15 and 16 there is a nut designed altered 59th Now forms itself the actuating 60th In the latter there is an arcuate slot 61 which is penetrated by the coupling pin 25th In the area of ​​the lower end of the arc slit 61 is the operating arm is a claw-shaped end 62 which also engages under the kingpin 25th The claw-shaped end 62 is supported on the slide 38th The pilot spool, the mandrel and the pressure spring bear like reference numerals. Furthermore, the guide of the slide and auxiliary slide is performed equivalently. On the nut 59 overlaid with a return stroke rotate a Zahnseg ment 63. This is equipped with an arcuate slot 64 in which a cam 65 of the nut 59 is immersed with backlash. Further, in a position opposite to the arcuate slot 64 is a slot segment 66 is provided for the passage of the coupling pin 25, which segment slot 66 to the arcuate slot 61 of actuating arm 60 covers. In the base-center position of the nut 59, the cam is 65 on to the upper end of the arc slit 64th The coupling pin 25 is located on the other hand on the lower end of the segment slot 66th

In a normal operating handle for retracting the latch 8, starting from the open position of the drive rods, the nut 59 is pivoted. According to the idle gear of the cam 65 and the coupling pin 25 in the slots 64 and 66 of the toothed segment 63 is no entrainment thereof. It is only the auxiliary slider 30 moves against the force of the compression spring in the upward direction, wherein pivoting the operating arm 60 themselves the catch tail 8˝ attacks and thus withdraws the case. After releasing the trigger then returns the nut 59 return to their normal center position in FIG. 15.

The locking of the now fully landscaped drive rod 67 requires an oppositely directed rotation of the nut 59, the toothed segment is entrained 63rd 68 whose toothing engages in the toothed ledge portion 69 of the drive rod 67 and displaces these in the downward direction. Now, when the handle is released, remains the sector gear 63 in its rotated position According to the idle gear, while the nut 59 druckfederbeaufschlagt returns to the basic center position. The backward movement of the connecting rod 67 in the open position requires a normal lever operated under returning the Zah'segmentes 63 in the position shown in Fig. 15.

Also with this embodiment described above is a unit in front, consisting of the nut 59, slider 38 and auxiliary slide 30, which allows simplified assembly of the espagnolette lock.

Further, Fig. 15 illustrates that the tooth segment 63 still has a further external toothing 70th Therefore, the sector gear 63 can also be in a third embodiment shown in FIG., See 17 and 18 using. The nut 59 and cooperating with their parts, which form a structural unit, in accordance with the foregoing configuration. The rod lock according to this solution has no case. There are two oppositely displaceable rods 71 ​​and 72 provided behind the faceplate first The lower drive rod 71 forms a tooth strip section 73 and the upper drive rod 72 of a tooth strip section 74th The toothed ledge portion 73 cooperates with the toothing 68 of the toothed segment 63, while the other toothed ledge portion 74, the teeth 75 of a second tooth segment 76 mesh. Stored this is above the nut 59 to a closed housing side standing peg 77. THe teeth 75 are located at a bent portion 78 of the sector gear 76. Furthermore, this makes for a tooth 79 which engages with the external teeth 70 of the sector gear 63. This means that the tooth engagement is performed in two different vertical positions.

According to the basic center position in FIG. 17 and 18, the nut can be displaced counterclockwise direction 59, said about the tooth segments, the connecting rods 71, travel for 72 apart. Thereafter, the nut 59 according to the force of compression spring 37 returns to the basic center position, while according to the idle stroke the toothed segment 63 remains in the twisted position. When then occurring displacement of the trigger in the sense of a normal door handle operation, the drive rods 71, 72 back to today shifted to the position shown in FIG. 17 on the tooth segments.

All mentioned in the description and shown in the drawing new features are essential to the invention, including those which are not expressly claimed in the claims.
