Description

The invention relates to an espagnolette lock according to the preamble of claim 1.

Corresponding espagnolette locks are known on the market. Such an espagnolette lock is also known from German Offenlegungsschrift 2 925 147. Due to the coupling between the connecting rod connecting slide and the connecting rod, a correspondingly large free space is required above the trap combined with a relatively large overall height of the lock housing.

The object of the invention is based on the task of designing an espagnolette lock of the type in question in a technically simple manner in such a way that, without reducing the espagnolette travel, a space requirement on the lock housing which is reduced above the trap is required.

This object is achieved by the invention specified in claim 1.

The subclaims relate to advantageous developments of the inventive solution.

As a result of such a design, an espagnolette lock of the aforementioned type is created, the lock housing of which can be produced in a reduced overall height, combined with a corresponding material saving. The angled leg facing the cuff is given an arrow-shaped profile with an arrowhead facing the trap. The angled leg of the drive rod connecting slide facing the cuff has a corresponding cross-sectional profile, so that the driving rod connecting slide is immersed in the groove of the trap is possible. So that the latching of these parts is ensured despite the trap being reversible, the latch head has contour-like grooves on both narrow sides. To retract the trap, a multi-armed deflection member is provided, the arms being arranged so that when the trap is retracted, an alternately loaded arm can plunge into the profile projection of the groove. The connecting rod connecting slide preferably has an angular design. When the drive rod connecting slide is displaced in the direction of the trap, its angled leg above the trap in the direction of the cuff can move into the open space that is open towards the narrow side thereof. This means that the case and the angled leg running towards the cuff, which is coupled in a suitable manner to the associated drive rod, overlap with one another. The overall height between the trap and the narrow edge can therefore be reduced by the extent of the covering. Optimal conditions result from the fact that the latch travels back with its fork opening over the angular section of the connecting rod connecting slide running parallel to the cuff. In this way you get a nesting of the angle leg with the right-angled angle section within the fork opening of the trap combined with a not inconsiderable space saving in the lock housing, which allows it to be made spatially smaller. For the purpose of further gaining space, the tail of the trap is forked, so that it is able to take up the arm of the deflecting member acting on it between the fork tines. This deflecting member fulfills a double function in that it can be acted upon by the intermediate member of the change lever arrangement on the one hand and by the nut actuating slide on the other hand. Lock components are also saved by that the change lever spring arranged in the end region of the intermediate member is at the same time the latch spring. When the latch is actuated to retract the latch, the alternating pushing movement of the intermediate member is translated into the retracting movement of the latch via the deflecting member. The change lever spring is advantageously designed as a compression spring. Its end on the link side is in a non-positive connection with one arm of the deflecting member, in such a way that it is tensioned when the nut is actuated to withdraw the trap. The spring wire passing through the compression spring is used for the non-positive connection, which continues beyond the fastening pin on the deflection member into a torsion spring section which loads the trap tail. Accordingly, the change lever spring works in two ways. On the one hand, it pivots the deflection member and thereby takes the trap with it. Furthermore, the torsion spring section also acts directly on the latch tail. The change lever spring can be made of the same material in that the spring wire connects to a bend in the last thread of the compression spring. In order to enable the compression spring to be charged, the end of the compression spring opposite the bend is supported on a stationary abutment. The latter is part of a carrier plate of the gear transmission, so that already existing components are used for the support function. The compression spring is loaded when the trigger is moved to retract the latch by a third arm of the deflecting member via the nut actuating slide that is inevitably carried along. The latter is located in a free space of the carrier plate, is loaded by a return spring and is in meshing engagement with the nut. Therefore, the nut actuating slide returns via this return spring after each shift and meshing back to the starting position. In order to obtain different dimensions of distance between the nut axis of rotation and the axis of rotation of the cylinder core, the nut is arranged in a bearing housing which is interchangeably inserted in the lock housing. Depending on the distance, a corresponding bearing housing is used, while the nut actuating slide can keep its structure. Then the tooth of the nut engages in the respective window of the nut actuating slide. At the same time, the bearing housing can also have a fitting plate screw passage hole arranged below the nut. The secure fixation of a hardware label is therefore always guaranteed. The aforementioned nut assembly can also be assigned to espagnolette locks with different backsets, without modification. This applies even to espagnolette locks with the smallest possible backset. The fact that the lower end of the intermediate link is articulated to the actuating arm of the change lever arrangement also contributes to this. The latter is spring-loaded against the direction of a toothed ring comprising the locking member hub of a locking cylinder and can be driven into the toothed ring actuation area by a control edge of the connecting rod connecting slide. The control edge accordingly moves parallel to the cuff and not, as in known designs, in the direction of the cuff, which helps to save space. When the latch is pulled back by alternating actuation, the actuating arm is first activated and then taken along by the sprocket actuating area. In the case of a closing rotation in the other direction in order to be able to lock the bolt, there is no engagement between the actuating arm and the gear rim actuating area. The correct closing operation of the espagnolette lock can therefore not be avoided. The area of application of the espagnolette lock can be increased by a pin that can be uncoupled through a hole in the lock top or bottom between the latch-side arm of the deflecting member and a slot equipped with a corresponding play of the trap, which can be turned around its longitudinal axis. The trap is given particularly good guidance by a guide groove which crosses into the slot on at least one broad side of the trap tail and into which an adapted guide projection of the lock cover and / or lock base protrudes. An advantageous further development is to be seen in giving the angled leg directed towards the cuff an arrow-shaped profile in cross-section with an arrowhead directed towards the trap. To ensure that these parts can be pushed into each other despite the trap being reversible, the latch head has contour-like grooves on both narrow sides. The turning of the trap is also made possible by the fact that each prong of the forked tongue has a slot, which slots are offset from one another by the turning shift. Depending on the installation of the trap, either one or the other slot is used in that the pin screwed into the trap arm of the deflection member dips into the slot of the trap tail with its end projecting beyond the trap arm. Turning the trap requires the trap to be pushed back so that the pin is aligned with the hole in the lock top or lock bottom. Then the pin can be unscrewed and then the trap can be removed and turned. Then the pin has to be screwed in again, its end then protruding into the other slot of the trap tail.

The espagnolette lock has a lock housing 2 connected to a cuff 1. The cuff 1 fastened to one narrow side of the lock housing 2 has a greater length than the lock housing 2 and extends over an upper and a lower drive rod 3 or, respectively, emerging from the lock housing 2. 4. The latter are provided with locking members 5 which cooperate with counter-closing parts, not shown, on the frame.

At the level of the narrow side walls 6, 7, bearing blocks 8 extend from the rear surface of the cuff 1 and continue to form a step in rearward-facing fastening projections 9. Seen in cross section, the fastening projections 9 projecting over the narrow side walls 6, 7 have a trapezoidal shape such that the base of the trapezium faces the interior of the lock housing. For the fastening projections 9, both the lock base 10 and the lock cover 11 running parallel thereto form insertion pockets 12 and 13 on the narrow side walls. The pocket 12 formed by the lock base 10 is obtuse-angled. One angular section 12 'lies against the facing side wall of the fastening projection 9, while the adjoining angular section 12''is supported flatly on the trapezoidal surface opposite the base. The angular section 12 ″ is equipped with a passage opening 14, which has a threaded bore 15 of the fastening projection 9 is aligned. Otherwise, this threaded hole runs parallel to the cuff 1.

The other insertion pocket 13 in turn also has an angular shape. The angle leg 13 'starting directly from the castle ceiling 11 is supported on the facing oblique flank of the trapezoidal fastening projection 9. The adjoining angle leg 13' 'extends over the angle leg 12' 'and lies flat on it. There the angle leg 13 '' is equipped with a hole 16. By means of a bolt 17 which extends through the insertion pockets 12, 13 and enters the threaded bore 15 of the fastening projection 9 and is designed as a screw, the cuff 1, lock base 10 and lock cover 11 can be connected to form a structural unit.

The outer surface 18 of the bearing blocks 8 is convexly curved. The outer surface of the fastening projections 9 and the insertion pockets 12, 13 formed by angled portions also extend within this convex curvature, cf. 5 and 6. This makes it possible to produce pockets on the doors that are adapted to the shape of the lock housing at the height of the bearing blocks 8.

Each bearing block 8 has a projection 19 with an oval cross section for fixing it on the cuff 1, which is inserted into a shape-adapted recess 20 of the cuff and riveted there, cf. 5 and 14 in particular.

Laterally the passage channels 21 for the drive rods 3, 4 form the bearing blocks 8 centering tabs 22, which in the form-fitting edge recesses of the lock bottom Immerse 10 and castle blanket 11. The aforementioned centering tabs 22 are flush with the outer surfaces of the lock base 10 and lock cover 11.

An additional fastening point between cuff 1 and lock base 10 is then also provided. Part of the same is a projection 24 fastened to the rear surface of the cuff 1, which extends in the area between the two bearing blocks 8. A threaded bore 25 is provided in the projection 24 for receiving a bolt 26, which is also designed as a screw. The latter runs parallel to the cuff 1, but is oriented at right angles to the other bolts 17, since it is screwed in through a hole 27 in the lock base 10. In this way, differently designed cuffs 1 with connecting rods 3, 4 can be connected to lock housings 2, which may also have different designs, with easy assembly.

In the exemplary embodiment, the lower drive rod 4 is forked in the region of the section crossing the bearing block 8. A longitudinal slot 29 is formed by the two fork tines 4 ', 4' '. Each fork 4 '. 4 ″ is provided with an angled end section E, E ′, which rest on the lock base 10 and plunge into form-fitting coupling recesses 31, 32 of a drive rod connecting slide 28 lying flat on the lock base 10. The aforementioned longitudinal slot 29 extends, moreover, at the level of a through hole 30 of the cuff 1 for a locking cylinder fastening screw 30 '.

A trap 33 is guided between the upper bearing block 8 and the projection 24. This has a trap opening 34 of the cuff 1, head 33 'equipped with a trap slope, to which a trap tail 33''adjoins the housing.

Below the latch 33, a bolt 35 is guided in the lock housing. Its locking head 35 'passes through a cross-section-adapted passage opening 36 of the cuff 1.

Between the bolt head 35 'and the lock base 10 there remains a distance which allows the drive rod connecting slide 28 to be passed through. In one end position of the same, the end section E 'can then pass under the locking head 35' combined with a small space requirement between the lower narrow side wall 7 and the locking bar 35.

The lock base 10 and the lock cover 11 hold a support plate 37 between them. This supports a toothed ring 39 in its lower area in a bore 38 facing the lock cover 11. The axis of rotation of the same is designated M1. The bore 38 is crossed by a locking cylinder insertion opening 40. The same is adapted to the outer contour of a profile locking cylinder 41. The axis of rotation M2 of the cylinder core of the profile lock cylinder used is eccentric to the axis of rotation M1, below the same, cf. Fig. 3.

The aforementioned ring gear 39 has a radially directed gap 42 for engaging a lock bit 43 of the profile lock cylinder 41, shown in dash-dotted lines. Two output gear wheels 44, 45 mesh with the external toothing of the ring gear 39. Their bearing journals, which are not described in more detail, extend in one piece from the carrier plate 37. In spite of the locking cylinder push-through gap 42 it is achieved that the ring gear 39 at least with an output gear 44 or 45 meshes. The rotation of the output gears 44, 45 is transmitted to an end gear 51 with the interposition of further reduction gears 46-50. The axle journals for the same are also part of the carrier plate 37. The carrier plate 37 thus contains all the pinion functional units.

The end wheel 51 meshes with the rack 52, which is guided parallel to the cuff 1 and is located at the free end of the connecting rod connecting slide 28. A further drive rod connecting slide 53 is guided in a parallel position opposite the rack 52. This forms a rack 54. The latter is assigned to the connecting rod connecting slide 53 in hook engagement 55 according to FIG. 10. In this way, the drive rod connecting slides 28, 53 are driven in opposite directions by the end gear 51 of the gear transmission. The aforementioned racks 52, 54 run on both sides of a section 37 ′ of the carrier plate 37 narrowed at the top.

The drive rod connecting slide 53 controls the interlocking with the interposition of a pivoting lever 56 in such a way that first the connecting rod connecting slide 53 leads the bolt exclusion and then the bolt 35 is taken along. As a result, the locking members 5 can first engage and cause the door to be tightened, so that the locking bar 35 can then move freely into the striking plate recess facing it.

The bolt 35 has on its bolt tail 35 'a run-up slope 57 which extends obliquely to the direction of movement of the bolt 35. This is formed by a lateral elevation 35''' of the bolt tail 35 '', which increase 35 '''leads on the lock base 10. The Elevation 35 '''is surmounted by a guide pin 58 which projects into a longitudinal slot 59 of the lock base 10 which extends in the direction of exclusion of the bolt 35. The run-up slope 57 is followed by a recess 60 for a control arm 61 of the pivot lever 56. The end of the control arm 61 is, as can be seen from the figures, shaped like a club.

The pivoted lever 56, which is mounted around a material-uniform pin 62 of the carrier plate 37, has on its side facing the connecting rod connecting slide 53 a ring gear section 63, the teeth of which cooperate with a toothed strip 64 of the connecting rod connecting slide 53. The rack 64 is located on an extension 65 of the connecting rod connecting slide 53 or the rack 54. When the bolt 35 is closed, this extension 65 extends in front of a locking edge 66 of the bolt tail 35 ″, cf. Fig. 9. The lower end edge 65 'of the extension 65 is also formed into an oblique flank, which cooperates with the ramp slope 57 in the manner described later.

The terminal tooth 63 'of the ring gear section plunges into a recess 67 of the drive rod connecting slide 53 which is approximately extended in accordance with the advance of the connecting rod connecting slide 53. This is a take-away game. When the game is over, the extension 65 has also released the bolt shift.

It can be seen in particular from FIG. 18 that the width of the bolt tail 35 ″ corresponds approximately to that of the lateral elevation 35 ″ ″. The latter is slightly wider. In the closed position of the bolt the bolt tail 35 ″ then overlaps the driven wheels 44, 45, which, however, are located on the opposite side of the carrier plate 37. The bolt tail 35 ″ extends in a cutout 68 of the carrier plate facing the lock base 10.

The pivot pin 70 of an actuating arm 71 of a change lever arrangement W is immersed in an arch slot 69 of the carrier plate 37 arranged below the bolt 35 concentrically with the axis of rotation M1. The actuating arm 71 is designed as a hook pawl pointing in the circumferential direction of the ring gear 39. For this purpose, the longer lever arm of the actuating arm 71 forms a hook 72 at the end, which is arranged in the same plane as a support ring shoulder 73 of the ring gear 39. In the basic position of the espagnolette lock illustrated in FIG. 3, which basic position allows the installation of a profile locking cylinder, the hook 72 is supported on the support ring shoulder 73. The latter forms a counter-hook 74 protruding into the movement path of the hook 72. A rod-shaped intermediate member 75 of the change lever arrangement W, which runs approximately parallel to the cuff 1, articulates on the shorter lever arm of the actuating arm 71. The lower, angled, coupling pin-forming link end 75 'protrudes in the direction of the lock base 10 and extends in the movement path of a control edge 76 of the drive rod connecting slide 28 which extends at right angles to the cuff 1. According to the basic position in FIGS Control edge 76, the end 75 'and thereby slightly pivots the actuating arm 71, which comes with its hook 72 against the support ring shoulder 73 of the ring gear 39. A leaf spring 77 clamped on the carrier plate 37 then acts on the end of the actuating arm 71 equipped with the hook 72. The same endeavors to To keep the actuating arm 71 in a neutral basic position, in which the hook 72 lies outside the movement path of the counter hook 74 of the ring gear 39. Such a neutral basic position of the actuating arm 71 is shown, for example, in FIG. 16.

The upper end region 78 of the intermediate member 75 is designed in the form of a plate and represents a plunger. An abutment 79 starting from the narrowed section 37 'of the carrier plate 37 and the opposite flank of the carrier plate section 37' serve to guide the end region 78. One end of the change lever spring 80 designed as a compression spring is supported on the abutment 79. The opposite end of the compression spring 80, on the other hand, is supported on laterally projecting shoulders 81 of the end region 78. The last thread there is continued via a bend 80 'into a spring wire 82 passing through the compression spring and wrapped above the abutment 79 a fastening pin 83 one with three Poor equipped deflection member 84 of the change lever arrangement W. For the mounting of the deflection member 84 is a pin 85 'starting from the narrowed portion 37'. The fastening pin 83 is located at the free end of the first arm 86 of the deflection member 84. This forms above the end region 78 a driving shoulder 87, which lies in the path of movement of the end region 78 of the intermediate member 75. The spring wire 82 wrapping around the fastening pin 83 continues beyond the fastening pin 83 and forms there a torsion spring section 82 'loading the latch tail 33''. The change lever spring 80 fulfills the function of a latch spring due to its special design. Basically, the change lever spring 80 strives to counteract the actuating arm 71 To shift in the direction of the gear rim actuation area.

At right angles to the first arm 86, a second arm 88 extends from the deflecting member 84, which projects between the fork tines of the forked latch tail 33 ″. Each prong of the forked latch tail 33 ″ each has a slot 89, 89 ′ running perpendicular to the direction of movement of the latch, which slots are offset from one another by the shifting movement. According to the exemplary embodiment shown, a pin 90 passes through the latch-side arm 88 of the deflection member 84 and establishes the driving connection to the latch 33.

In the retracted position of the latch 33, the pin 90 is aligned with a hole 91 in the lock cover 11. Then the pin 90 designed as a grub screw can be unscrewed and the latch 33 can be turned about its longitudinal axis, so that the screwed-in pin 90 with its protruding end in dips the slot 89 'of the other fork.

Crossing the slot 89, 89 ', a guide groove 92 is provided on each broad side of the latch tail 33' ', into which a guide projection 93 protrudes from the lock cover 11 and lock base 10.

The third arm 94 extends approximately diametrically opposite to the first arm 86 in order to engage a nut actuating slide 95. The latter is located in a space left by the carrier plate 37 within the lock housing 2 and is loaded by a return spring 96. Furthermore, the nut actuating slide 95 is in meshing engagement with a nut 97, which is divided into two parts in an interchangeably inserted in the lock housing 2 Bearing housing 98 is rotatably arranged. Its length corresponds to a multiple of the nut diameter. The nut actuating slide 95 forms on the back a plurality of windows 99 for one engagement of a tooth 97 ', the nut 97. In the exemplary embodiment, the tooth 97' engages in the lower two windows 99 arranged one above the other. The bearing housing 98 forms a fitting plate screw passage hole 100 arranged below the nut in the form of an elongated hole. This bearing housing 98 is designed with the nut 97 and the nut actuating slide 95 as a completely preassembled structural unit which can be inserted into a contour-matched recess A of the lock base and lock cover, in parallel extension to the narrowed support plate section 37 '. In the embodiment, this unit is set to a distance between the axis of rotation of the nut and that of the cylinder core to 72 mm.

13 shows a modified bearing housing 98 ', which can accommodate a nut 97 and the actuating slide 95 without modifying the same. Then the tooth 97 'of the nut engages in the upper window 99 of the nut actuating slide 95. Below the nut bearing point, a fitting plate screw passage hole 100 'extends within the bearing housing 98'. The outline contour of the bearing housing 98 'can correspond to that of the bearing housing 98 described above, so that only the modified nut housing 98' has to be installed in order to change the distance between the locking cylinder and the nut. A spacing of 92 mm between the axis of rotation of the locking cylinder and the axis of rotation of the nut 97 is realized by means of the structural unit illustrated in FIG. 13. Additional spacing dimensions would be possible by designing the bearing housing accordingly.

The basic positions of the nut are realized in a known manner by stops. Similarly, the rotary end positions of the nut stops are assigned, which are not dealt with in more detail.

The third arm 94 of the deflection element 84 lying in the movement path of the nut actuating slide 95 is forked. The fork opening 33 '' 'is penetrated by the connecting rod connecting slide 53. The drive rod connecting slide 53 continues into the area of the latch tail 33 ″ and merges into an angle leg 101 lying transversely to the cuff 1, which can be moved into the fork opening of the latch tail 33 ′. In the displaced position, the latch travels with its fork opening over the angular section 102 of the connecting rod connecting slide 53 which runs parallel to the cuff 1 and which angular section 102 extends through the fork opening of the third arm 94. The angled leg 101 directed towards the cuff 1 has an arrow-shaped profile, cf. 4. The arrow head is turned towards the trap 33, and the trap head 33 'forms contour-like grooves 103 on both narrow sides. Seen in the direction of movement of the trap, the trap passage opening 34 of the cuff 1 corresponds to the outline shape of the trap head, which means that the trap is turned over 33 allowed by 180 °.

On the upper flank, the angled leg 101 forms a coupling projection 104 at its free end, which protrudes into a recess 105 adapted to the cross section at the free end of the upper drive rod 3. A displacement of the connecting rod connecting slide 53 is therefore inevitably transferred to this connecting rod 3.

Since the angle leg 101 can step into the range of motion of the latch head 33 ', a smaller distance between the facing narrow side 6 and the latch 33 is sufficient, which allows a lower overall height of the lock housing. The fact that the end section E 'of the drive rod 4 can overlap the bolt 35 also contributes to this.

The upper rear edge of the lock edge of the lock housing 2 forms an approximately angular bulge 106. A contour-matched corner angle 107 located between the lock base 10 and lock cover 11 limits this bulge toward the rear narrow side of the lock housing. The end regions of the corner bracket 107 are provided with threaded bores 108, 109 which allow the connection to the lock cover 11 and the lock base 10. The bulge 106 framed by the corner bracket 107 forms with its rounded inner apex a fitting plate screw through-hole 110. One leg of the bulge 106 is oriented vertically and runs parallel to the cuff 1, while the other leg is directed at an acute angle to the cuff and extends in the upward direction.

The depth of the bulge 106 lying in the facing direction extends over the extension of the connecting line L of the nut 97 and the fitting screw passage hole 100, cf. Fig. 1.

If a door equipped with the illustrated espagnolette lock is provided with a long plate 111, shown in phantom in FIG. 1, this can be held by means of three screws 112, 113 and 114. The upper fastening screw 112 enters the bulge 106 and thus extends above it the nut storage area. The second fastening screw 113 passes through the fitting plate screw passage hole 100 of the bearing housing 98, while the third fastening screw 114 runs below the lock cylinder and the lock housing 2. This measure makes it possible, for example, to only loosen the central fastening screw 113 in order to then be able to remove the espagnolette lock. The long signs do not have to be dismantled for this purpose, as is usually the case.

Another bulge 115 is provided in the area of the lower corner of the lock housing 2. This is formed by the rear contour of the support plate 37, which contour the lock cover 11 and the lock base 10 are adapted in the corresponding area.

The bulge 115 extends rearward of the lock cylinder 41. A depth of the bulge 115 is selected such that the bulge bottom 115 'of the lock cylinder longitudinal axis is closer than the distance between the lock cylinder longitudinal axis and the faceplate adjoining faceplate screw passage hole 122. This having carrier plate 37 forms with its rear narrow side wall the bulge bottom, which runs obliquely towards the cuff 1. Finally, there is a third bulge 116 on the rear wall of the lock housing 2. The latter extends in the area rearward of the nut 97. The depth thereof facing in the facing direction is at least so great that the bulge bottom 116 'is closer to the nut center than the distance between the nut center and the fitting screw passage hole adjacent to it, which is located on the face plate and which is held by the carrier plate 37 is designed as slot 120. The two aforementioned bulges 115, 116 allow the door instead of the long signs in the area of the nut and the locking cylinder in FIG. 1, rosettes 117, 118 indicated by dash-dotted lines. One fastening screw 119 for the rosette 117 passes through the elongated hole 120 of the support plate 37, while the other fastening screw 121 penetrates the door in the region of the bulge 116. The elongated hole 120 and the bulge 116 also permit the use of differently shaped bearing housings 98 for the nut, in order to be able to implement different spacing dimensions between the nut bearing point and the axis of rotation of the cylinder core.

A fastening screw 122 'which penetrates the through hole 122 of the carrier plate 37 and a fastening screw 123 which is arranged diametrically thereto and which runs in the region of the bulge 115 serve to hold the rosette 118 surrounding the locking cylinder.

Even with the arrangement of the rosettes 117, 118, it is sufficient to unscrew the fastening screw opposite the bulge in order to be able to remove the espagnolette lock.

The carrier plate 37 with the gear transmission and the change lever arrangement W and the bearing housing 98 represent structural units. If drive rod locks with different backset dimensions are to be created, these structural units need not be modified. Rather, it is sufficient to extend or shorten the castle floor and castle ceiling, while the rear area remains unchanged, including the bulges. Corresponding reductions and extensions are then to be made for the bolt and the latch and the connecting rod connecting slide 28. However, due to this slight change, a wide range can be used differently designed locks manufacture combined with reduced manufacturing costs and reduced storage.

The following mode of operation occurs: According to FIG. 3, the lock is in the basic position, which allows the locking cylinder 41 to be inserted. The key slot then does not align with the gap 42 of the ring gear 39. After installing the locking cylinder 41 and removing the key, the position of the ring gear 39 can be seen in FIG. 16. Along with the slight twisting of the ring gear 39, the reduction gear and the End wheel 51 of the connecting rod connecting slide 28 is displaced slightly in the downward direction, so that due to the spring loading the actuating arm 71 is pivoted counterclockwise in such a way that its hook 72 has come out of the path of movement of the counter hook 74 of the ring gear 39.

The latch can be withdrawn in the key withdrawal position when the bolt 35 is closed by pushing the button. The nut 97 is pivoted into the position illustrated in FIG. 16 via the pusher (not illustrated). Their tooth 97 'shifts the nut actuating slide 95 in the downward direction. The third arm 94 of the deflecting member 84 lying in the path of movement of the nut actuating slide is acted upon by pivoting the deflecting member 84 clockwise. The second arm 88 forming the latch arm pulls the latch 33 back via the pin / slot connection. During this pivoting of the deflection element 84, the change lever spring 80, which also serves as a latch spring, is tensioned. After the pressurization has ended, the nut 87 and the nut actuating slide 95 return their basic position, which is limited by the stroke. Furthermore, the change lever spring 80 leads the deflection member 84 into the starting position by relaxing.

The change lever operation is shown in Fig. 17. To do this, turn the ring gear 39 clockwise by pressing the key. At the same time, the end gear 51 is carried along via the gear transmission, which leads to an upward displacement of the connecting rod connecting slide 28, as a result of the tooth engagement. The control edge 76 of the connecting rod connecting slide 28 acts on the end 75 'of the intermediate member 75 accompanied by a pivoting of the actuating arm 71 in the clockwise direction, which pivoting is limited by the hook 72 resting on the support ring shoulder 73. By continuing to actuate the key, the hook 72 and the counter hook 74 come into contact with one another and entrainment of the actuating arm 71, the pivot pin 70 of which moves upward within the arch slot 69 of the carrier plate 37. Along with this, the intermediate link 75 is carried along in the upward direction. Its end portion 78, which forms a tappet, acts on the driving shoulder 87 of the first arm 86 of the deflecting member 84. As a result, the deflecting member 84 pivots and takes the latch 33 with it in the lock inward direction via the second arm. During this process, the change lever spring 80 is charged. If the key is brought into the key withdrawal position after the door has been opened, the ring gear 39 rotates back by the appropriate amount. At the same time, the changeable fog spring 80 can relax, pivots the deflection element 84 counterclockwise and drives the latch 33 into its forward position.

The locking of the bolt 35 requires an opposite closing rotation. About the ring gear 39 and the reduction gear and its end wheel 51, the drive rod connecting slide 28, 53 are driven in opposite directions by meshing. The direction of movement of the connecting rod connecting slides 28, 53 is indicated in FIG. 9 by arrows. The drive rods 3, 4 with the locking members 5 attached to them are dragged along. As long as the extension 65 is in front of the locking edge 66 of the bolt tail, the bolt 35 cannot protrude. Accordingly, the pivot lever 56 does not change its position. This means that the connecting rod connecting slides advance with the connecting rods. After the niche 67 which allows the advance of the connecting rod connecting slides 28, 53 has passed, the terminal tooth 63 'of the ring gear section 63 is acted upon. Shortly before, the extension 65 has also released the locking edge 66 of the locking tail 35 ″. This is the case after turning a key. The locking of the bolt 35 therefore only begins when the door has been sufficiently tightened by the corresponding locking members. Accordingly, the bolt can also dip into its associated striking plate recess without interference. During the further closing rotation, the pivoting lever 56 is then rotated via the tooth engagement while simultaneously taking the bolt into the pre-closing position illustrated in FIG. 18. After two locking rotations, the control arm 61 acts on a stop 124 of the carrier plate 37. In this pre-locking position, the key can be removed. Any push-back forces acting on the bolt are directed into the locking cylinder via the tooth engagement.

The locking of the bolt 35 is done by the opposite closing rotation. Along with this, the drive rod connecting slides 28, 53 are driven in opposite directions in the opposite direction of the arrow via the end wheel 51 and the toothed rack engagement. After completing a closing rotation of approximately 540 °, the position shown in FIG. 19 occurs. Then the rack 64 comes out of engagement with the toothing of the pivot lever 56. Nevertheless, the bolt 35 is closed, since then the rearward displacement is taken over by the extension 65 by the lower, obliquely directed end edge 65 'acting on the run-up slope 57 of the bolt tail 35' 'and thereby forcing the backward displacement with simultaneous entrainment of the bolt 35. In the final phase of the return rotation, the extension 65 thereby again comes in front of the locking edge 66 of the bolt tail 35 ″.
