Abstract

The invention relates to an espagnolette lock with an accessory lock (1) which is controlled by a central lock and which has a bolt (22) coming into hook-shaped engagement with the lock plate. In order, when the bolt is closed, effectively to absorb push-back forces exerted on this in the pre-closed position, a slotted control of the bolt (22) breaking the path of movement of the bolt (22) down into different portions is provided, in such a way that, during locking, a control pin of the bolt is first guided in a slot guided diagonally to the direction of movement of the espagnolette, to ensure that the hook engages behind the lock plate, and thereafter penetrates into a slot portion arranged parallel to the direction of movement of the espagnolette. <IMAGE>

Description

The invention relates to an espagnolette lock with an additional lock controlled by a central lock according to the preamble of claim 1.

Such espagnolette lock is known from DE-OS 27 32 471, the hook-shaped engagement being achieved in that the bolt of the additional lock pivots about a fixed pin of the lock case. To move the bolt head, which runs concentrically to the bolt pivot point, a drive rod extending from the central lock is used, the pin of which engages in a slot of the bolt of the additional lock extending transversely to the direction of displacement thereof. With this design, however, there is no blocking of the pre-locked bolt against turning back. Rather, corresponding push-back forces loading the bolt must be absorbed by the central lock.

The object of the invention is based on the object of designing an espagnolette lock of the type in question of a technically simple construction in such a way that, in addition to a favorable movement sequence of the bolt when it is closed, attacking push-back forces in the locked position are effectively absorbed.

This object is achieved by the invention specified in claims 1 and 21.

The subclaims represent advantageous developments of the inventive solution.

As a result of such an embodiment, a generic drive rod lock is created which, in addition to a structure which is advantageous in terms of locking technology, is distinguished by an increased security value. If the bolt is to be brought into its locking position, the drive rod is moved across the link control assigned to the bolt and the bolt is extended transversely to the faceplate longitudinal direction. During this bolt movement, the bolt passes through the associated entry opening of the striking plate. After the bolt head has entered the locking engagement opening of the striking plate, the movement of the bolt directed transversely to the extension displacement is associated with the fact that its locking head engages in hooking engagement with the locking engagement opening of the striking plate. This ensures that the hook engagement is achieved with certainty. If the bolt is in this composite engagement generated in this way, push-back forces acting on the bolt head are unable to move the bolt into the release position while increasing the locking security of the drive rod lock. The release position must be brought about by the will, namely by moving the drive rod, caused by the central lock. A variant according to the invention is characterized in that the bolt, when excluded by the link control, essentially moves on a linear path at an obtuse angle to the drive rod. This direction is opposite to the hook engagement. Superimposed with this linear movement there is still a pivoting of the bolt head opposite to the hook engagement. This means that when locking, the locking head first steps over the cuff and the locking head engages in the locking engagement opening. Only when this has been done will there be a further drive rod shift across the scenes Control of the bolt pivoted to achieve the hook behind the bolt head on the striking plate. So that despite this control of the bolt and the required free space of the bolt head in the bolt passage opening of the bolt receives additional support, a base is provided on the front surface of the bolt which fills the bolt passage opening of the faceplate in the locked position. The base only engages in the bolt passage opening in the closing end phase. In a technically simple manner, the link control is formed by a slot / pin engagement. As long as the pin is in the slot section lying parallel to the drive rod displacement during the initial phase of the exclusion, there is no change in the position of the bolt. Only when the pin engages in the slot section directed at the cuff at an acute angle does the essentially linear exclusion of the bolt take place at an obtuse angle to the drive rod movement, combined with the small pivoting of the bolt head mentioned at the beginning. If the pin has passed through the slit section which is directed at an acute angle to the cuff, it can engage in a slit section which is also parallel to the drive rod movement, locking the locked position of the bolt. The push-back forces acting on the bolt are therefore effectively absorbed by this slot section. Before the peg sitting on the bolt has completely passed through the slit section directed towards the cuff, the pivoting movement of the bolt occurs. This results from a superposition of its displacement in the area to the slotted section at an acute angle and an abutment on a stop surface on the faceplate located at a lever arm distance from the slot control point back. The corresponding control of the bolt can be done by exclusive slot control. However, the structure of the link control is simplified if the bolt is spring-loaded in the exclusion direction. This ensures that the bolt moves on a correct path despite only a single slot slot during the locking displacement. Manufacturing and assembly advantages result from the fact that the bolt lies in a pocket of a connecting rod connecting piece, the bottom of which has the slot sections. The bolt is therefore also located at a protected location on the guard lock.

However, according to a further embodiment of the invention, it is possible to achieve the hook engagement without swiveling the bolt. For this purpose, a bolt emanates from the bolt tail, which extends through both a link slot of the connecting rod connecting piece guided in the additional lock and also an angular housing-side guide slot thereafter. One angle leg of this guide slot runs at right angles to the cuff, ie in the direction of exclusion, and the other angle leg is directed parallel to the cuff. By shifting the connecting rod, the bolt is initially locked in a straight line through the slot slot. The pin runs through one angle leg. As soon as the pin comes into the angular apex of the angular guide slot, the transversely directed movement of the bolt takes place with the hook behind the handle. The locking of the bolt takes place in the reverse way, firstly lifting the hook behind the hook and secondly closing the bolt. One edge works when the bolt is closed and the one when it closes other flank of the backdrop slot. Frictions during the closing process are reduced by a rolling element that can be rotated on the pin and which rolling element runs along the edge of the link slot. The slot slot can be designed so that it forms parallel opposite slot edge. However, there is a version that the slit in the direction of the gauntlet widens towards its upper end and that an energy accumulator that charges when the bolt is excluded and loads it into engagement is provided. The further the bolt is excluded, the more the energy accumulator is charged. As soon as the peg of the bolt lies at the level of the angular apex of the guide slot, the energy accumulator can be discharged, the bolt being suddenly moved in the hook engagement direction. During this process, the pin sitting on the bolt also suddenly enters the angled leg of the angled guide slot, which runs parallel to the cuff. The speed at which the bolt moves in the transverse direction to the cuff is greater than that of the connecting rod connecting piece. As soon as the pin acts on the lower edge of the slot, the energy accumulator still supports the movement of the connecting rod connecting piece. The transverse displacement of the bolt is complete when its pin has completely passed through the angled leg running parallel to the cuff. The widening of the link slot then allows the connecting rod connector to be moved even further, creating tolerance compensation if the closing process requires a further path of the connecting rod connector. So that the bolt remains in its straight-line position in relation to the cuff during the forward and backward closing, the energy accumulator, which is designed as a compression spring, is supported at one end on the drive rod gen connector and at the other end on a sliding block that comes against the bolt. The corresponding support surface of the sliding block runs at right angles to the cuff and thus always determines the position of the transom. This system is also maintained when the bolt moves into the hook engagement position. When the bolt is closed, the bolt is initially disengaged from the hook by the lower edge of the slot. The bolt and sliding block as well as the energy accumulator loading them move synchronously. When the bolt on the bolt side has reached the angular apex of the guide slot, the bolt is moved back through the lower edge of the slot edge. This relocation is supported by the partially loaded energy accumulator, which is then discharged during the closing relocation. So that the sliding block remains in its correct position, it carries a guide pin which extends through a transverse wall of the connecting rod connecting piece. This fulfills an additional function in that it also holds the compression spring.

When the bolt is extended in a straight line and the transverse movement thereof is subsequently carried out, a free space is created at the bolt passage opening. So that the bolt cannot be shifted back under the influence of constraining forces exerted transversely to its direction of exclusion while removing the hook behind the hook to the frame-side striking plate, the remaining free space is filled by a locking lug in the bolt's closed position. They are only controlled when the door is closed correctly. Constraining forces occurring on the bolt are therefore unable to bring the locking lug into the release position via the bolt. The espagnolette lock is therefore given an increased security value. With closed back gel, in turn, fills the entire bolt passage opening, so that the locking tab itself is not visible when the door is open. The latter is part of a spring-loaded pawl and, when the closed position is reached, occurs together with the spring-loaded pivoting of the pawl into the form-filling position in the free space of the bolt passage opening. In the closed position, the play between the bolt-side pin and the link slot of the connecting rod connecting piece is so great that before reaching the corresponding edge of the slot edge of the bolt, its narrow edge acts on the locking nose of the pawl. The bolt and the corresponding components can therefore only be moved back by operating the drive rod in accordance with the regulations. For this purpose, the pawl is mounted on the connecting rod connector and spring-loaded in the direction of its locking engagement. The angled end of the pawl forms on its narrow side facing the bolt passage opening edge an actuating flank which takes effect when the connecting rod connecting piece moves back. In the first phase of the closing movement, the pawl consequently pivots out of engagement with the free space of the bolt passage opening. This pivoting is possible because there is the corresponding game between the bolt-side pin and the link slot. The peg / slot mounting of the pawl allows a sudden entry of the locking lug into the free space in the closing end phase. While the bolt is being closed, the locking lug still encompasses a projection lying in its path of movement, which forms the connecting lug of the housing to the faceplate. In order to enable trouble-free driving around the projection, the top surface of the locking lug is also designed as a control flank. Your targeting is in such a way that in the open position it is at an acute angle to the faceplate inner surface and thus permits the projection to overflow, starting from the open position. So that the bolt does not leave its correct orientation during the shifting of the locking mechanism, a guide slide which is carried along by the bolt during its transverse movement is provided. This is in the slot / pin connection with the bolt, the slot of which runs in the direction of the extension displacement of the bolt. The guide slide itself is T-shaped in such a way that the ends of the T-legs lie in fork pieces of the connecting rod connecting piece. These allow the guide slide to move in the drive rod movement direction. The guide slide, on the other hand, is carried via the slot in the T-bar, in which the bolt on the bolt side is non-rotatably guided. This configuration makes it possible to dispense with a spring-loaded slider.

In a further additional lock according to the invention, the bolt is designed as a pivot bolt which can be pivoted about a pivot axis and which can engage in hook-like engagement with the striking plate. The bolt couples with a control pin in a control slot of a link that can be driven by the drive rod. Due to the diagonal arrangement of the control slot, an arc-shaped locking movement is driven by the linear drive rod movement. Due to the control slot section which runs parallel to the drive rod movement and which adjoins the diagonal control slot at the end, the excluded bolt is blocked against being pushed in when the drive rod is completely displaced. In this embodiment, too, the bolt can only be shifted into the additional lock housing by a willpower-shifting drive rod. According to a preferred Ausge The diagonally extending slot section has a slot section angled at an obtuse angle to the drive rod movement, the slot section running parallel to the drive rod movement adjoining the angled slot section. The length of this angled slot section, which runs at an obtuse angle to the drive rod movement, is dimensioned such that when the pin passes over when the bolt is moved forwardly into the angled slot section, the tightening slope formed on one side on the bolt head of the bolt fully projects from the faceplate. This configuration is particularly advantageous in terms of use, since there is therefore a link control of the bolt that can be dismantled into different sections, and during the first exclusion phase, in which the control pin is guided in the acute-angled slot section, it is initially only displaced by a small angle. This has the consequence that a relatively large torque can be transmitted with its tightening slope in the striking plate during the immersion of the bolt. On the other hand, only a small torque can be transmitted during the second pre-closing phase, in which the locking pin is guided in the obtuse-angled slot section, but this is advantageously associated with a large angular displacement with the same relative linear rod displacement. In this phase, in which the tightening slope has emerged completely from the cuff, no great torque is required, since in this phase there is no longer any tightening movement, but only the pivot bolt is pivoted completely into the counter-locking part. A further advantageous development is provided by a guide slot running parallel to the drive rod movement in the link, which is provided by a guide slot in the lock housing that forms the pivot axis Bearing pin of the bolt is penetrated, and its length corresponds to the drive rod stroke. This makes it possible to adjust the area of the entire lock width in order to achieve optimal guidance. It is further provided, in addition to the guide slot on the side facing away from the faceplate, to extend the end of the control slot by a slot section running parallel to the drive rod movement, in order to lock the locked position of the bolt. A minimal length of the bolt tail is achieved in that the control pin lying in the control slot can be displaced from a position adjacent to the rear wall of the housing, assigned to the locked bolt position, beyond the imaginary extension of the guide slot, to a position adjacent to the faceplate, which is assigned to the excluded bolt position. Reliable guidance of the link in the lock housing is achieved by means of a guide rib which runs parallel to the movement of the connecting rod and is stamped into the cover of the housing, in order to grip the guide claws of the link to guide the link on the housing base.

The espagnolette lock shown in FIGS. 1-8, relating to the first embodiment, has an additional lock 1 controlled by a commercially available central lock (not illustrated). The cuff 2 of the same is formed by an extension of the faceplate of the central lock. A driving rod 3 controlled by the central lock runs behind the cuff 2. The angled end 4 of the latter protrudes into the housing 5 of the additional lock 1.

In particular, the housing 5 has a lock base 6 fastened to the cuff 2 and at right angles thereto. From this, lock case side walls 7, 8, 9 are angled, on which a lock cover 10 is supported. This is held by fastening screws 11 which engage in stud bolts 12 fastened to the lock base 6. In the housing 5 in the direction of the drive rod 3 displaceable connecting rod connector 13 is guided. This forms a niche 14 at the lower end for inserting the bent end 4 of the drive rod 3. In the middle, the connecting rod connecting piece 13 is provided with a recess 15 forming a pocket. The recess floor 16 slides on the inner surface of the castle floor 6 and is equipped with a slot slot 17. Specifically, this is made up of one adjacent to the rear wall of the castle, parallel to the greenhouse slit section 18 extending in the opposite direction, a slit section 19 directed at an acute angle in the direction of the cuff 2 and a slit section 20 adjoining the latter, likewise extending parallel to the drive rod movement. The slot section 19 connecting the two outer slot sections 18, 20 running parallel to one another runs at an angle of approximately 45 °.

The slotted slot 17 acts together with a pin 21 of a bolt 22 guided in the housing 5. This bolt has a bolt head 23 which, when the bolt 22 is completely closed, closes with the front surface of the cuff 2 and which projects into a bolt passage opening 24 thereof. The bolt head 23 is provided with a bevel 25 on the side facing the viewer. A bolt tail 26 connects to the bolt head 23. Between this and the bolt head 23, a cutout 27 extends on the underside of the bolt, so that the bolt head 23 protrudes like a hook. The above-mentioned pin 21 is located near the rear flank of the bolt tail 26 in the upper third of the same. The pin 21 is so long that it protrudes beyond the slot slot 17 and still engages in a guide slot 28 of the lock base 6 directed at right angles to the drive rod displacement.

On the flank facing the bolt head 23 and formed by the cutout 27, the bolt tail 26 is equipped with a stop surface 29 obtained by beveling.

Furthermore, the latch 22 is spring-loaded in the direction of exclusion. For this purpose, a torsion spring 30 is attached to the lower stud 12 of the lock housing 5 shorter leg 31 is supported on the rear lock housing wall, while the other, longer leg 32 acts on the bolt tail 26 below the pin 21 and thus pivots the bolt 22 into the position according to FIG. 3.

The following mode of action occurs:

The locking of the latch 22 requires a displacement of the drive rod 3 in the downward direction by means of the drive rod lock, not shown. Accompanying this, the connecting rod connecting piece 13 moves in the downward direction. During the beginning movement sequence, the bolt-side pin 21 travels through the slot section 18 of the link slot 17. As long as the pin 21 is in the slot section 18, the bolt 22 does not change its position, see in particular FIGS. 3 and 4. FIG. 4 illustrates that the upper edge 23 'of the bolt head 23 to the cuff 2 includes an acute angle alpha. During the further displacement of the drive rod, the slot section 19 running at an acute angle comes into effect. As a result of this, the latch 22 initially experiences an outward movement from an essentially linear path lying at an obtuse angle to the drive rod 3, with a slight pivoting opposite to the hook engagement. This leads to the angle alpha 'between the upper flank 23' of the locking head 23 and cuff 2 being smaller than the angle alpha. In the course of this largely linear displacement of the bolt, the abutment surface 29 of the bolt tail 26 acts on the back of the faceplate, see FIG. 5. Then the pin 21 is still in the acute-angled slot section 19. In the position of engagement, the bolt tail 26 becomes the faceplate 2 by the spring 30 held. If the drive rod displacement continues, so The remaining length of the slot section 19 running at an acute angle causes the bolt 22 to pivot into the position according to FIG. 6. This pivoting takes place in the direction of a hook engagement with a striking plate (not shown). When the drive rod is displaced further, the slot section 20 adjacent to the cuff 2 and running parallel to it then moves relative to the pin 21 into the position according to FIG. 7. As a result, the latch 22 is secured against pivoting back or pushing back. Corresponding forces are accordingly not conducted into the illustrated central lock or need not be absorbed by it. During the preliminary shift, the pin 21 has entered the other end region of the guide slot 28 of the lock base 6.

Furthermore, it must also be stated that after pivoting of the bolt 22 into the hook engagement position, a base 33 of the bolt tail 26 adjoining the bolt head 22 has filled in the bolt passage opening 24 of the cuff 2. Thus the latch 22 receives additional support in the upward direction.

The opening of the bolt 22 takes place by the upward movement of the drive rod 3. First, the bolt 22 pivots in the release position. Then it is pulled inwards by the link control in the starting position according to FIG. 3.

The additional lock according to the second embodiment, which is illustrated in FIGS. 9-13, bears the reference number 34. Its housing 35 is fixed to the cuff 36 leading to the central lock (not shown). The structure of the housing 35 corresponds that of the first embodiment. In the interior of the housing 35, a connecting rod connecting piece 37 is guided parallel to the longitudinal direction of the cuff 36. The connecting rod connecting piece is displaced by a connecting rod 38.

In the central area, the connecting rod connecting piece 37 is provided with a pocket 39. In the recess bottom 40 formed by this pocket 39 there is a slotted slot 41 which increases in the direction of the cuff 36 and widens towards its upper end 42. The recess bottom 40 lies directly on the lock bottom 43 of the housing 35. A bolt 44, which is composed of a bolt head 45 and a bolt tail 46, slides on the inside of the recess bottom 40. A cutout 47 extends between the latter and the locking head 45 to form a locking head 45 projecting like a hook.

A pin 48 is embedded in the bolt tail 46. This passes through the slot slot 41 and then an angular guide slot 49 of the lock base 43. The guide slot 49 has the right-angled to the cuff 36 angle leg 49 ', the one above the cuff 36 adjacent apex 49' in the parallel to the cuff 36, formed shorter Angle leg 49 ‴ passes over. The diameter of the pin 48 is adapted to the width of the guide slot 49. The link slot 41, however, has a larger width than the guide slot 49. At the level of the link slot 41, the pin 48 carries a rolling element 50. Its outer diameter corresponds to the diameter of the link slot 41 at its lower end 42 '. The transitions in the widespread upper end 42 'are also with the diameter of Roll body 50 corresponding radii. These radii connect the upper and lower edge of the slot 51, 52 with a slot edge 53 directed parallel to the cuff. The widened upper end 42 of the link slot is, seen in the longitudinal direction of the lock, at the same height as the angle leg 49 ‴ of the guide slot 49.

From Fig. 13 it can be seen in particular that the bolt head 45 is wedge-shaped to form acute-angled tightening slopes 54 and 54 'which cooperate with an engagement opening of the striker plate, not shown.

Another component of the additional lock is a block-like sliding block 55. This has a runner 57 which strikes the upper locking edge 56, the latter running parallel to the locking edge 56 and being directed at right angles to the cuff 36. The sliding block is guided in the direction of the drive rod displacement. For this purpose, the side of the slider opposite the runner 57 projects past a guide pin 58 which passes through a bore 59 in a transverse wall 60 of the connecting rod connecting piece 37. The guide pin 58 is the carrier of an energy accumulator K, which in turn is designed as a compression spring 61. This is supported on the one hand on the inside of the transverse wall 60 and on the other hand on the bottom of a blind hole 62 of the sliding block 55.

The operation of the additional lock according to the second embodiment is as follows:

The closing of the bolt 44 requires a downward movement of the drive rod 38. As a result, the drive rod connector 37 is taken along. Whose the upper edge of the slot 51 presses against the roller 50 rotatable on the pin 48 so that the bolt 44 is advanced with the pin, that is to say extends. During this movement, the energy storage compression spring 61 is loaded, since the sliding block 55 is supported with its runner 57 on the upper edge 46 of the bolt 44, cf. Fig. 10. As soon as the bolt-side pin 48 has reached the angle apex 49˝ of the guide slot 49, the energy storage compression spring 61 is discharged and displaced via the sliding block 55, the fully extended bolt 44 in the transverse direction, that is to say in hook engagement with the striking plate. The speed at which the bolt moves is greater than that of the connecting rod connecting piece 37 in the downward direction. The energy storage compression spring 61 ensures that, if the bolt 44 has not yet been fully extended, it is fully advanced. The achievement of the hook behind is therefore always guaranteed. As soon as the pin 48 reaches the lower edge of the slot edge 52, the connecting rod connecting piece 37 and the bolt 44 move synchronously with one another. The complete hook engagement position is when the pin has reached the lower end of the angle leg 49 ‴. Then the slotted slot 41 widened towards the upper end still allows a certain displacement of the connecting rod connecting piece 37. In normal cases, however, the position of the pre-closed and secured bolt according to FIG. 11 is present. Then any push-back forces acting on the bolt 44 are absorbed by the angle leg 49 ‴ of the angular guide slot 49 and accordingly conducted into the lock housing 35.

The closing requires an oppositely directed displacement of the drive rod 38, that is to say in an upward direction tung. The bolt 44 is taken along via the lower, rising edge 52 of the slot. Since it moves synchronously with the connecting rod connecting piece 37, the energy accumulator K does not exert any force to be overcome. This can only be effective if the pin 48 of the bolt 44 reaches the angle apex 49˝ and from there is moved with the bolt in the direction of the angle leg 49 '. Then the energy accumulator in conjunction with the slot edge 52 acts as a supporting component when closing the bolt, utilizing the energy of the energy accumulator that is still stored. An intermediate phase when closing back is illustrated in Fig. 12, wherein the pin 48 has just entered the angle leg 49 'of the angular guide slot 49.

In the third embodiment illustrated in FIGS. 14 to 23, the additional lock 63 has a housing 64. This is fastened to the cuff 65 leading to the central lock (not shown) of the drive rod lock. For this purpose, connecting tabs 67, which form projections, are bent on both sides of the bolt passage opening 66 from the lock base 68. Each connecting strap 67 is penetrated by a rivet 69 which is guided through the cuff 65 in order in this way to connect the lock housing to the cuff to form a fixed structural unit. The lock set-up is covered by a lock cover 70 into which the angled ends of the connecting straps 67 are inserted.

In the interior of the housing 64, a connecting rod connecting piece 71 is guided parallel to the longitudinal direction of the cuff 65. On this engages a drive rod 72 leading to the center lock, not shown. A closing operation of the same is accordingly transferred to the Espagnolette connector. The central lock is preferably constructed in such a way that two closing rotations correspond to a complete displacement of the connecting rod connecting piece 71.

The drive rod connector 71 lying flat on the lock base 68 has in the central region a slotted slot 73 which rises in the direction of the cuff 65, the two opposite ends of which merge into niches 74, 75 which run parallel to the direction of displacement of the drive rod connector. At the level of the slot slot 73 is on the connecting rod connector 71, a bolt 76, which is composed of a bolt head 76 'and a bolt tail 76˝. The bolt head 76 'forms a bolt tail 76˝ in the transverse direction projecting hook projection 76 ‴. At the same level, the bolt head 76 'has a cross section which corresponds to that of the bolt passage opening 66.

The bolt tail 76˝ carries on its side facing the connecting rod connector 71 a projecting guide pin 77, which is slightly smaller in diameter than the width of the slot slot 73. The length of the guide pin 77 corresponds approximately to the thickness of the connecting rod connector 71st An the guide pin 77 is followed by a cross-sectionally offset pin section 77 'which plunges into an angular guide slot 78 of the lock base 68. The pin portion 77 'corresponds in diameter approximately to the width of this angular guide slot 78. The latter consists of a right angle to the cuff 65 angle leg 78' and a parallel to the cuff 65 angle leg 78˝ together, which is shorter than the other angle leg is designed. The angle vertex 78 ‴ connecting the two angle legs is rounded.

The guide pin 77 'opposite side of the bolt tail 76˝ is also provided with a protruding pin 79, which is rectangular in shape such that its greatest length is in the direction of the bolt exclusion. This pin 79 fits into a slot 80 of a guide slide 81 that runs in the direction of the extension displacement of the bolt 76. In plan, the guide slide 81 has a T-shape and accordingly forms a T-web 82 and the two T-legs 83 projecting from it. The aforementioned slot 80 is located in the T-web 82. The T-legs 83, on the other hand, are guided by fork pieces 84 of the connecting rod connecting piece 71, which are angled in the direction of the lock cover 70.

Another component of the lock mechanism is a pawl 85. At its upper end it forms a short slot 86, into which a pin 87 on the connecting rod connection side is immersed. In the open position, the pin 87 extends at the lower end of the slot 86 of the pawl 85, see FIG. 16. The end of the pawl 85 opposite the bearing point is angled in the direction of the cuff 65 and forms a locking lug 88. The pawl 85 is of one arranged on a standing pin 89 of the connecting rod connector 71 arranged torsion spring 90 so that the locking lug 88 is forced into contact with the inner surface of the cuff 65. The angled end or the locking lug 88 forms on his or her the bolt passage opening edge 66 'facing the narrow side a modulation flank 91. At an acute angle to this extends the top surface 92 of the locking lug 88, which top surface also serves as a modulation flange ke is designed. In the open position according to FIG. 16, the head surface control flank 92 extends at an acute angle to the inner faceplate and above the corresponding projection 67.

The operation of the espagnolette lock is as follows: If the middle lock, not shown, is actuated by means of a key, this leads via the drive rod 72 to entrainment of the espagnolette connector 71 in the downward direction. Due to the bolt-side guide pin 77 lying in the niche 74, the connecting rod connecting piece 71 is displaced in the initial phase without pre-closing the bolt 76. The pre-closure starts only when the upper edge of the slot 73 'of the slot slot 73 acts on the guide pin 77. After the key has been rotated 360 ° on the central lock, the position shown in FIG. 18 is on the additional lock 63. Along with the previously described sequence of movements, the pawl 85 has been carried over the pin 87 of the connecting rod connecting piece. The locking nose control flank 92 passes over the projection 67 and inevitably leads to a pivoting of the pawl 85 against spring loading. In the course of the further locking operation, the position of the additional lock 63 according to FIG. 20 is reached after about one and a half key turns of the central lock. Then the locking lug 88 of the pawl 85 completely bypasses the projection 67 and also the rivet 69. Furthermore, the guide pin 77 is immersed in the upper recess 75 of the slot slot 73. Along with the locking of the bolt 76, the pin portion 77 'has passed through the apex 78 ‴ between the two angle legs 78', 78˝ of the guide slot 78 at the level of the shorter, parallel to the cuff 65 angle leg 78 ' while forcing a certain downward displacement of the bolt 76, which, however, is already immersed in a counter-striking plate, not shown, during its straight forward closing. During the further closing process, the hook engagement behind the striking plate is then achieved. After executing two closing rotations on the central lock, the position according to FIG. 21 is present. In the final phase of the transverse displacement of the bolt 76, the pawl 85 could pivot spring-loaded in the direction of the cuff 65, the locking lug 88 being immersed in the remaining free space F of the bolt passage opening 66. In this position, the guide pin 77 is located in the upper recess 75 of the link slot 73, while the pin portion 77 'starting from the guide pin 77' is located at the lower end of the angle leg 78 'of the guide slot 78. During the closing process, the guide slide 81, which is in the pin / slot connection to the bolt 76, has also been displaced relative to the connecting rod connecting piece 71.

Coercive forces occurring in the longitudinal direction of the bolt are absorbed on the one hand by the joint engagement between the striking plate and the bolt head. On the other hand, the pin portion 77 'is supported on the vertically extending angle leg 78˝ or the wall thereof. Attack on the bolt 76 in the longitudinal direction of the drive rod 72 directed forces, so the upper longitudinal edge 93 of the bar abuts the locking lug 88, which in turn is supported on the bolt passage opening edge 66 '. In any case, the game between the guide pin 77 of the bolt and the lower edge of the slot edge 73˝ is greater than the distance between the longitudinal edge of the bolt 93 and the locking lug 88, so that the lower edge of the slot edge 73˝ cannot come into effect. Accordingly, the locked position is maintained.

Opening the additional lock requires key actuation of the center lock, the key of which is to be turned in the opposite direction, associated with an upward displacement of the drive rod 72 and the connecting rod connector 71. In the initial phase of the upward movement of the connecting rod connector 71, the pawl 85 is immediately over taken the pin 87, which is now at the upper end of the slot 86 of the pawl 85. The modulation flank 91 cooperates with the facing bolt passage opening edge 66 'and inevitably leads to a pivoting of the pawl 85 against spring loading. The niche 75 allows the displacement of the connecting rod connecting piece 71 without directly taking the bolt 76 in the upward direction, that is to say in the transverse direction to its excluding direction, so that the actuation of the pawl 85 can take place without problems. With the further closing operation is then dragged along by the upward driving rod 72 and connecting rod connector 71 over the lower edge of the slot edge 73˝ the latch in the upward direction and then withdrawn, the pin portion 77 'of the guide pin 77 passing through the angular slot 78. During this displacement, the locking lug 88 bypasses the projection 67. As a result, the modulation flank 91 on the projection 67 becomes effective by pivoting the pawl 85 against spring loading. As soon as the pawl 85 has bypassed the projection 67, the torsion spring 90 can reset, which pivots the pawl 85 in the direction of the cuff 65 such that the pin 87 is then again in the lower region of the slot 86 in accordance with the basic position of the additional lock in Fig. 16.

Another additional lock according to the invention is shown in Figures 24-32, the bolt now as Swivel bolt 122 is designed, which is pivotably mounted with a bearing pin 123 in the lock base 139 and the lock cover 134. On the lock floor, a link 131 is guided, which has a guide slot 130 which runs parallel to the drive rod displacement direction and which is penetrated by the pivot pin 132 of the pivot bolt and whose length corresponds to the drive rod stroke.

To control the pivot bolt 122, the link 131 has a control slot 117, in which a control pin 121 of the bolt 122 engages. The control slot 117 has a diagonally extending region 119 and at the end in each case an adjoining slot section 118 and 120 which runs parallel to the drive rod displacement direction. The diagonal portion of the control slot is divided into an obtuse-angled slot portion 119 'and an acute-angled slot portion 119'.

The swivel bolt 122 consists of a bolt head 123 and a bolt tail 126, the mounting of the bolt 123 around the bearing pin 123 being in the bolt tail region. The control pin 121 is located in the transition area between the bolt tail and bolt head. The hook-shaped swivel bolt 122 has a bevel 125 on the head side. The tightening bevel is formed on one side, and it has the task of pulling the door or the like to be locked against the counterlocking part during the locking of the bolt and its engagement in the striking plate of the counter-locking part, the locking part coming onto the tightening bevel 125.

In order to securely guide the link 131 on the lock base 139, the link has guide claws 138, 137 at each end, which enclose guide ribs 135, 136 stamped into the lock cover.

The swing latch operates as follows: In the position shown in Fig. 26, the swing latch 122 is in the fully closed position. The locking pin 121 is now located in the slot section 118 running parallel to the drive rod movement. When the drive rod displacement begins, combined with a downward displacement of the link 131, the control pin 122 emerges from the slot section 118 running parallel to the drive rod movement and, as shown in FIG. 27, enters the diagonal slot section 119˝, which connects to the parallel section 118.

A subsequent displacement of the link 131 initially causes the latch 122 to move relatively slowly.

Fig. 28 shows the additional lock in one position, wherein the swivel bolt has been displaced so far that the bevel 125 has completely come out of the cuff. The boundary 140 between the chamfered area of the bolt head 125 and the non-chamfered area of the bolt head is flush with the faceplate in this position. The control pin 121 is in this position in the transition into the obtuse-angled slot portion 119 ', which is angled towards the drive rod opposite the slot portion 119'. A further displacement of the link causes a relatively large pivoting movement of the bolt compared to a comparatively small lifting movement of the link.

In the position shown in FIG. 29, the locking pin emerges from the obtuse-angled slot section 119 'and into the slot section 120 running parallel to the drive rod displacement direction.

30 shows the additional lock with the swivel bolt 122 fully closed. The locking pin 121 is supported in this position in the slot section 120 running parallel to the drive rod movement direction. In this position, the swivel bolt is secured against being pushed back, since the slot wall of the slot 120 is loaded when the swivel bolt is loaded from the outside only a normal force is exerted on this diaphragm wall.

The additional lock is controlled by a central lock, which has a lockable bolt. This bolt has two pre-closing positions, a first pre-closed position corresponding to the closing position of the additional lock shown in FIG. 28, so that the swivel bolt 122 only protrudes from the cuff 102 to such an extent that the boundary 140 between the beveled area and the non-beveled area of the Bolt head aligned with the faceplate. Only when the bolt is locked twice does the pivot bolt assume its completely excluded position shown in FIG. 30.
