The drive rod lock shown in Fig. 1 1, which can be fastened on the narrow side of a door 3, has a face plate 2, which is a flat profile piece of metal and carries the various components of the drive rod lock 1 which can be inserted in the thickness of the door 3. On the faceplate 2 sit the housing 4 of a middle lock part, the housing 5 of an upper lock part, the Ge housing 6 of a lower lock part and a spring housing 7 . Additional lock parts can be provided.

In the faceplate 2 slots 11 ( Fig. 6) for the implementation of displaceable to them zugeementen or pulling pin 8 are provided. In Fig. 1 three suit elements 8 are shown. Each suit element 8 consists of a roller 9 which is rotatably mounted about a central axis 10 ( FIGS. 6 to 8), which in turn is fastened to a part 12 which, adjacent to the inside of the cuff 2 , is displaceable parallel to it.

The suit pins 8 act with complementary elements which are provided on a door frame surrounding the door 3 and have an inclined guide so that when they lower or raise the door 3 is pressed against the seal provided between the door and the door frame. In the position shown in dashed lines in FIG. 1, the pulling pins 8 are in their position with a sealing function.

Opposite the inside of the face-plate 2, a drive rod 13 is arranged, which is parallel to the face plate 2 to be longitudinally displaceable. In the faceplate 2 , an opening 18 is provided for the implementation of a Hauptrie gel 15 . Corresponding openings are provided in the faceplate 2 for an upper additional bolt 16 or a lower additional bolt 17 . The positions of the main bolt 15 and the bolt to 16 and 17 with safety function are shown in broken lines in Fig. 1. In these positions, the main latch 15 and the additional latches 16 and 17 engage in corresponding counter locking plates in the door frame.

The espagnolette lock 1 has control devices C, to which the espagnolette 13 belongs and which during a first period provide a sealing function without affecting the safety function and during a second period the safety function without affecting the already existing sealing function.

The control devices C enable the safety function only when the sealing function is fully guaranteed by correct positioning of the pulling pin 8 for the seal with respect to the complementary elements of the door frame. If the sealing function is inadequate, the correct positioning of the pull-in pins 8 can be achieved by the action of a locking lug 42 on one end 63 of a slide 62 ( FIGS. 2 to 5) or by the action of a nut (not shown) on the drive rod 13 by lifting a latch (not shown) before the safety function is triggered, which follows the sealing function via the drive rod 13 .

The drive rod 13 ensures in its vertical displacement in a first phase of its path that the pulling pins 8 assume the position shown in broken lines in FIG. 1, after which a further displacement of the drive rod 13 only for extending the main bolt 15 and the additional bolts 16 and 17 leads, which are also shown in phantom in Fig. 1. In the course of the later phase of the displacement of the drive rod 13 , the pull pins 8 remain in their position shown in dash-dotted lines.

As seen in FIGS. 2 and 3, the control means C have a finger-shaped Ausklinkele element 19 that protrudes through an opening in the face plate 2 and is hinged about an axis parallel to the longitudinal direction of the face-plate 2 axis 20 which is vertical when the espagnolette 1 is arranged on the door 3 .

A spring 21 in the form of a hairpin, the shafts of which are arranged vertically and which is held at the level of its head 22 on the housing 4 , ensures that the end of one of the shafts provides an elastic return of the release element 19 to a locking position, which is shown in FIG. 4 is in which the inner end 23 of the release member 19 engages under a shoulder 24 of a drive rod connecting slide 25 (in Fig. 12 125), which is part of the drive rod 13 and a connection between the section 26 a lying substantially above the housing 4 the driving rod 13 and the substantially below the housing 4, section 26 b of the operating rod 13 ensures.

When the releasing member 19 assumes the position of Fig. 4, it resists downward of the driving-rod connecting slide 25 and the operating rod 13 by the the spring housing 7 associated spring is caused in the downward direction 28 movement (Fig. 6 to 8).

The spring 28 is a helical compression spring which is arranged around a cylindrical pin 29 , the lower end of which is fastened to the bent-back lower end of the part 12 carrying the axle 10 and a head 37 is seated at the other end. The part 12 has at its lower end two legs 30 , 31 of different lengths. The longer leg 30 carries at its upper end the axis 10 of a roller 9 and is supported abge on the inner surface of the cuff 2 . The leg 30 also has an elongated hole 32 with a vertical longitudinal extension. A guide pin 33 passes through the elongated hole 32 and is fastened on the face plate 2 and protrudes toward the pin 29 . The other leg 31 of the part 12 carries a pin 34 which projects on the side facing away from the leg 30 and which passes through an elongated hole 35 with a vertical longitudinal extension. The elongated hole 35 is recessed in the section 26 a of the drive rod 13 , which is bent out at the height of the arrangement formed by the part 12 , the pin 29 and the spring 28 so that a concave zone is formed, inside the part 12 , the spring 28 and the pin 29 are arranged.

The spring 28 is supported at its upper end on a stop 36 forming a piece with the faceplate 2 . The stop has a cylindrical passage through which the pin 29 passes and ends in its head 37 .

When the door 3 slams shut, the release function 19 automatically triggers the sealing function as follows: The pivoting of the release element 19 ( FIG. 4) about its vertical axis 20 releases the connecting rod connecting slide 25 , so that the compressed spring 28 causes the part 12 to move downward brings together with the assembly unit formed by the drive rod 13 , whereby the rollers 9 are shifted accordingly.

The sealing function is ended by the stroke end of the spring 28 and by the positioning of a tooth 48 supported on a lock attack. As a result, all pull-in pins 8 are in position for the start of the safety function.

With the aid of control devices C for the espagnolette lock 1 , the main bolt 15 and the additional bolts 16 and 17 are actuated such that the safety function is carried out by the movement of the espagnolette 13 following the sealing function.

As shown in Fig. 2 to 5, the transversely to the faceplate 2 and thus horizontally displaceable main bolt 15 has a guide or groove 38 , which has a vertical upper section 39 , which is followed by a downwardly inclined section 40 with respect to the vertical direction , A on the connecting rod connecting slide 25 attached pin 41 cooperates with the groove 38 . When the drive rod lock 1 is open, the pin 41 is located at the upper end of the section 39 , as shown in FIG. 4. In the position for the sealing function, but not in the position for the safety function, the pin 41 assumes the position of FIG. 2, ie it is located at the lower end of the section 39 of the groove 38 and at the upper entrance of the inclined section 40 , In the position for the safety function, the pin 41 is located at the lower end of the inclined portion 40 , as shown in FIG. 5.

The vertical displacement of the connecting rod connecting slide 25 and the connecting rod 13 into the position of the safety function takes place, for example, through a locking lug 42 of a cylinder 43 actuated by a key.

The locking lug 42 interacts in a known manner with a tumbler 44 having a plunger 45 , which can be moved horizontally in a slideway 46 under the action of the locking lug 42 as it rotates, thereby compressing a return spring 47 . A with the plunger 45 a piece-forming tooth 48 engages in notches 49 , 50 , 51 , 52 which are located on one side of the lock attack, which forms a narrow section of the drive rod 25 slide. On its other side, the castle attack limited by horizontal transverse edges tour recesses 53 , 54 , 55 , which cooperate with the locking lug 42 .

The control devices C of the espagnolette lock 1 are designed such that when the door 3 is opened by means of a key, the reset into the position of the sealing function after the bolt 15 has been withdrawn by an additional rotation of the locking lug 42 or by the action of a nut (not shown) in direct engagement with the connecting rod connecting slide 25 is reached.

In a first rotating portion of this additional rotation, the sense takes place in Fig. 2 to 5 clockwise, presses the locking lug 42 by cooperating with the horizontal transverse edge 53 b of the notch 53 directly to the top of the driving-rod connecting slide 25.

The drive rod connecting slide 25 has in its upper region a groove 56 with a curved shape, which cooperates with a pin 57 carried by one end of a lever 58 .

The lever 58 is articulated substantially at a quarter of its length on an axis 59 carried by the housing 4 , the shorter lever arm being located between the pin 57 and the axis 59 . Towards its other end, the lever 58 has a further pin 60 which engages in a slot guide 61 in a sinusoidal shape, which has a buckling zone essentially at half its length. The slot guide 61 is provided on the upper section of a slide 62 which is vertically displaceable in the housing 4 . This slide 62 has at its lower end a nose 63 with which the locking lug 42 cooperates during a second rotation section of its additional rotation, as shown in FIG. 3.

If the locking lug 42 has its first rotation section fully ends during its additional rotation and no longer acts on the connecting rod connecting slide 25 , in order to then pass through its second rotating section, locking devices 25 against the action of the spring 28 are provided for holding the connecting rod connecting slide 25 and the connecting rod 13 intended.

In the embodiment of FIGS. 2 to 5, the locking devices I have a pawl 64 which is fixed in the vertical direction by a slideway 65 forming a piece with the housing 4 , but is slidable in the horizontal direction perpendicular to the drive rod 13 . The pawl 64 may transition from the retracted position shown in FIG. 2 to an active position shown in FIG. 3 under the action of an inclined guide 66 provided on the upper portion of the slider 62 . The guide 66 cooperates at the end of the vertical upward movement of the slide 62 with a corresponding inclined surface of the pawl 64 which, as can be seen from FIG. 5, is pressed transversely, ie horizontally, to the left. The pawl 64 is held in each of its positions, ie in its retracted position of FIG. 2 and its active position of FIG. 3 by a bistable spring 67 , one end of which in the side wall of the housing 4 and the other end on the pawl 64 is anchored.

The drive rod connecting slide 25 has a notch 68 near its upper end, into which the left end of the pawl 64 engages when the notch 68 reaches the height of the pawl 64 . This happens when the locking lug 42 reaches the end of the first rotation section of its additional rotation. The lower surface 69 of the locking notch 68 is inclined to the vertical so that it can push the pawl 64 back, whereby the connecting rod connecting slide 25 can continue its upward movement when the locking lug 42 executes the second rotary section of its additional rotation.

In FIGS. 9 to 11, the control means C are shown for an upper auxiliary bolt 16, which can also be used for the lower auxiliary locking elements 17. The control device C of FIGS. 9 to 11 first provide the sealing function and then the safety function, in response to a corresponding movement of the drive rod 13 . The section of the drive rod 13 which actuates the upper additional bolt 16 is designated by 26c. The upward movement of section 26 c is based on the downward movement of section 26 a ( FIGS. 2 to 5) by a reversing device in the form of a bell crank and by two diametrically opposed toothed racks 70 which cooperate with a pinion 71 and in each case on one Edge of the sections 26 a, 26 c are provided.

The upper additional bolt 16 is assigned to an upper pull pin 8 . For the displacement of the drive rod 13 , conversion devices T are provided in order for the tightening pin 8 to have an effect on the additional bolt 16 in response to a first displacement phase of the drive rod 13 in the position for the sealing function and during a second period of time the additional bolt 16 in response to the first to bring a second phase of displacement of the drive rod 13 without affecting the pull pin 8 in the position for the safety function of FIG. 11.

The conversion devices T located in the upper housing 5 have the toothed rack 70 , which is provided on an edge of the section 26 c and can set the pinion 71 in rotation, which is rotatably seated on an axis 71 a, one of which has the faceplate 2 Piece forming part is worn. The pinion 71 has a cam 72 that is integral with it. The cam 72 has a central groove 74 , which is connected at its ends to a first groove 73 and a third groove 75 .

The axis 10 of the roller 9 of the pull pin 8 is supported by the end of a part 76 . The part 76 is vertically slidable by a system of pins and slots, which are provided on the part 76 and on the Ge housing 5 . The part 76 carries a pin 77 engaging in the first groove 73 in the area of its lower right corner. The pin 77 and the axis 71 a lie in a vertical plane. The sealing function is achieved by lifting the roller 9 from the position shown in FIG. 9 to that shown in FIG. 10. For this purpose, the first groove 73 has a pole radius which increases progressively when the cam 72 rotates counter-clockwise under the action of the section 26 c raised by the spring 28 . The pin 77 is pushed away from the axis of rotation 71 a of the pinion 71 and the part 76 is raised.

The middle groove 74 is formed by an arc that is concentric to the axis 71 a of the pinion 71 . If the sealing function is ensured, as can be seen in FIG. 10, the pin 77 is just entering the central groove 74 .

The additional bolt 16 has for its horizontal displacement an elongated hole 16 a, which cooperates with a pin 16 b provided in the housing 5 . At its end opposite its closing side, the additional bolt 16 has an upwardly extending bolt tail 78 . At its upper end, the bolt tail 78 carries a pin 79 which engages in the central groove 74 on the step side when the roller 9 is in the lower position. The pin 79 and the axis 71 a lie in a horizontal plane.

In the lifting phase of section 26 c, in which the pulling pin 8 moves from the position in FIG. 9 to the position in FIG. 10, the pin 79 passes through the central groove 74 , which is thus centered on the axis of rotation 71 a of the cam 72 that the pin 79 remains immobile with respect to the housing 5 .

The additional latch 16 remains in its retracted position. In the position with the sealing function of FIG. 10, the pin 79 just enters the third groove 75 . The third groove 75 has a pole radius that decreases when the cam 72 continues its counterclockwise rotation about the axis 71 a.

During the second lifting phase of section 26 c, the pin 79 approaches through its a grip in the third groove 75 again the axis 71 a, whereby the additional bolt 16 moves out of the face plate 2 and comes into the position for the safety function. In the course of this phase, the pin 77 connected to the pull-in pin 8 passes through the central circular groove 74 , where the pin 77 remains immobile and locked.

The control devices C can be used with a downward movement of the drive rod 13 in direct connection without a reversing device T.

The operation of the espagnolette lock 1, starting from the illustrated in Fig. 4 and Fig. 9 positions shown of the main bolt 15 and auxiliary bolt 16 at an open door 3.

When the door 3 is closed , in particular by slamming, the release element 19 pivots due to its interaction with the door frame. The inner end 23 of the Ausklinkele element 19 moves away from the shoulder 24 in a direction substantially perpendicular to the plane of FIG. 4, so that the connecting rod connecting slide 25 is released for a downward movement. The spring 28 of the spring housing 7 relaxes ( Fig. 7) and presses the section 26 a and with this the connecting rod connecting slide 25 and the entire driving rod 13 down.

The pin 41 forming a piece with the connecting rod connecting slide 25 lowers from the upper position shown in FIG. 4 to the middle position shown in FIG. 2 by passing through the vertical section 39 of the guide 38 which gel 15 on the immovable main drive 15 is provided.

During this first phase of the downward movement of the drive rod 13 , the pin 8 (roller 9 and axis 10 ) extend through the elongated hole 11 and come into position for the sealing function. This first phase ends with the head 37 ( FIG. 7) resting on the stop 36 and the tooth 48 being positioned in the notch 50 .

For the actuation of the upper additional bolt 16 , the section 26 c of the drive rod 13 changes from the position in FIG. 9 to the position in FIG. 10 during a first movement phase. The pinion 71 and with it the cam 72 are set in rotation.

The pin 77 forming a piece with the part 76 carrying the pull-in pin 8 is shifted there in the first groove 73 . This leads to a vertical displacement of the pin 77 and thus of the pull-in pin 8 . The movement of the pull-in pin 8 achieved in the course of this first displacement phase of section 26 c effects the sealing function through interaction with the complementary elements seen on the door frame.

By lowering the connecting rod connecting slide 25 , as can be seen in FIG. 2, the lever 58 is caused to rotate counterclockwise due to the interaction of the groove 56 and the pin 57 .

The pin 60 carried at the end of the lever 58 located away from the groove 56 runs through the slot guide 61 and lifts the slide 62 , which thereby changes from the lower position shown in FIG. 4 to the upper position shown in FIG. 2. This passage is possible since the locking nose 42 in the open position of the espagnolette lock 1 releases the lug 63 and the position shown in Fig. 4 is in a with respect to approximately 45 ° clockwise Turned th position.

When the upper position is reached, the slide 62 moves the pawl 64 through its guide 66 from the position shown in FIG. 4 to the position on the left shown in FIG. 2. In this position the left edge of the latch 64 cooperates with a lying above the notch 68 edge 25 along a of the driving-rod connecting slide 25, whereby it is removed is located towards the left further from the slideway 65 as the located just below the notch 68 lower edge 25 b of the connecting rod connecting slide 25 . As a result of this change in the position of the pawl 64 , the bistable spring 67 pivots from its one stable position, in which it holds the pawl 64 to the right, to its other stable position ( FIG. 2), in which it presses the pawl 64 to the left.

To produce the safety function, the cylinder 43 is turned with the key so that the locking lug 42 is rotated counterclockwise, the action of the locking lug 42 on the lug 63 ensuring the safety function.

According to FIG. 2, the locking lug 42 first moves the plunger 45 when it rotates counterclockwise, ie opposite to the arrow in FIG. 2, acting on its upper inclined surface in such a way that the tooth 48 is pushed back and the connecting rod connecting slide 25 for vertical downward movement.

Continuing their rotation counterclockwise, the locking lug 42 interacts with the lower transverse edge 54 a of the notch 54 and takes the connecting rod connecting slide 25 downward.

The pin 41 is moved downward in the inclined section 40 of the guide 38 , as a result of which the main bolt 15 is extended by the face plate 2 .

In the second rotation of the locking lug 42 counterclockwise, it interacts with the transverse edge 55 a of the tour recess 55 , as a result of which the connecting rod connecting slide 25 and with it the connecting rod 13 are lowered.

The pin 41 forming a piece with the connecting rod connecting slide 25 reaches the lower end of the section 40 , as shown in FIG. 5. The main latch 15 is extended to the maximum for the safety function. This also applies to the upper additional latch 16 and the lower additional latch 17 .

In the exemplary embodiment shown in FIGS. 9 to 11, the upper additional bolt 16 is controlled on the basis of the movement of the section 26 c of the drive rod 13 . The position with the sealing function is shown in Fig. 10.

During the first rotation of the key, which causes the locking lug 42 to rotate counterclockwise, the section 26 c rises so far that the rotation of the pinion 71 and the cam 72 causes the pin 79 forming a piece with the additional bolt 16 to form a section of the third groove 75 can run through, which causes a partial extension of the additional bolt 16 . During the subsequent rotation of the locking lug 42 , the resulting rotation of the cam 72 essentially moves the pin 79 to the end of the third groove 75 , as shown in FIG. 11, which corresponds to the maximum extension of the additional bolt 16 .

During this rotation of the cam 72 , the pin 77 forming a piece with the part 76 supporting the pull pin 8 passes through the central circular groove 74 centered on the axis of rotation of the cam 72 , so that the pin 77 and with it the pull pin 8 with respect to the housing 5 remain immobile.

In order to open the door 3 starting from the position shown in FIG. 5, the locking lug 42 is rotated in the clockwise direction shown by an arrow in FIGS. 2 to 4 using the key.

In the first opening rotation, the locking nose 42 acts upon withdrawal of the tumbler 44 with the upper transverse edge 55 b of the Tourausnehmung 55 together and lifts the slider 25 at Treibstangenan circuit. When the locking lug 42 leaves the transverse edge 55 b, the tooth 48 , which has been pushed back to the left, enters the locking notch 51 and prevents a downward movement of the connecting rod connecting slide 25 .

In the meantime, the pin 41 moves upwards in the inclined section 40 of the guide 38 , as a result of which the main bolt 15 begins to move to the right into the face plate 2 .

During the following rotation of the locking lug 42 , the main bolt 15 again assumes the position shown in FIG. 2. The groove 56 of the connecting rod connecting slide 25 is again in contact with the pin 57 , which is located at the beginning of the groove 56 .

The safety function is now canceled while the sealing function is still available.

To eliminate the sealing function and reset the spring 28 , the key is rotated from the retracted position of the main bolt 15 of FIG. 2 by an additional key turn clockwise.

During a first rotary section of this rotation of the locking lug 42, after the tumbler 44 has been withdrawn, it interacts with the edge 53 b of the tour recess 53 .

In this first rotary section of the additional rotation, the locking lug 42 lifts the connecting rod connecting slide 25 directly and compresses the spring 28 directly.

Before the locking lug 42 reaches the end of the first rotary section and releases the transverse edge 53 b, the locking notch 68 of the connecting rod 42 raised by the locking lug 42 slide 25 is moved to the right on the pawl 64 , which is pressed by the spring 67 into engagement with the locking notch 68 as shown in FIG. 3.

When the locking lug 42 leaves the edge 53 b, the connecting rod connecting slide 25 is prevented from moving downwards under the action of the spring 28 , the compression of which has started.

The pin 41 , which again moves upwards in the vertical section 39 of the guide 38 , has no effect on the main bolt 15 , which remains in its retracted position. It is the same at the level of the upper additional bolt 16 ( FIG. 10), because the pin 79 moves in the circular central groove 74 which is concentric with respect to the axis of rotation of the cam 72 .

By the upward movement of the connecting rod connecting slide 25 , the rotation of the lever 58 is caused due to the interaction of the pin 57 and the groove 56 , as shown in FIG. 3. The lever 58 rotates clockwise around its axis 59 and the pin 60 provided on its other end moves along the slot guide 61 and pushes the slide 62 so that the nose 63 can interact with the locking nose 42 .

In the course of a second, in the position shown in Fig. 3 rotating section of its additional rotation clockwise, the locking lug 42 cooperates with the lug 63 of the slide 62 so that it is moved downward, as can be seen in Fig. 4 is.

Since the distance between the axis 59 and the pin 60 is larger (approximately three times larger in the present example) than the distance between the axis 59 and the pin 57 , the resistance force of the spring 28 to be compressed is reduced at the height of the nose 63 , so that the force exerted by the user on the key to rotate the locking lug 42 remains acceptable.

When the locking lug 42, the end of this second rotary portion reaches the additional rotation, the pawl is pushed back 64 by the inclined portion 69 of the notch 68, during the return provided by the spring 21, inner portion of the Ausklinkelements 19 engages under the shoulder 24 and the driving-rod connecting slide 25 against the action of the spring 28 holds.

The espagnolette lock 1 has returned to its open position shown in FIG. 4. The corresponding position of the upper additional bolt 16 is shown in FIG. 9.

In the embodiment of FIGS. 12 to 14, locking devices I are provided for holding the connecting rod connecting slide 125 belonging to the connecting rod 113 when the locking lug 142 no longer points to the return of the spring 28 ( FIGS. 6 to 8) in the course of its additional rotation Espagnolette connecting slide 125 acts.

Referring to FIG. 12-14142 affects the closing nose of a horizontal bolt tail 80 carried Tourausnehmungen and transmits the horizontal displacement directly on the latch, while in the preceding examples, the locking lug 42 shift in a vertical Ver caused the notches, the horizontal in a shift the bar was converted. The rest of the functioning of the espagnolette lock and the reference symbols for the components with the same function remain unchanged.

The connecting rod connecting slide 125 connected to the connecting rod 113 is moved under the effect of the spring 28 ( FIGS. 6 to 8) when the door is closed by slamming vertically downward into the position for the sealing function.

The locking devices I have a fixed on the faceplate 102 horizontal cross pin 81 with reduced dimensions. The transverse pin 81 carries a pin 82 which is slidable and which is perpendicular to the plane of FIGS . 12 to 14. On the pin 82 is applied by a arranged around the cross pin 81 compression spring 81 a pressure. The pin 82 projects through two elongated vertical longitudinal slots 83, 84, which ranges 125 extending intermediate portion 85 are provided in the forming part of the drive rod 113 driving-rod connecting slide 125 and in a vertically along the driving rod connecting slide.

The intermediate part 85 is vertically displaceable relative to the face plate 102 . In the intermediate part 85 is a tongue cut out 86 which is bent at right angles to the plane of the intermediate part 85th The tongue 86 is located between two elastic return springs 87 , 88 , each of which has a guide block 87 a, 88 a forming a piece with the face plate 102 . Each guide block 87 a, 88 a has a bore with a vertical axis through which a pin 87 b, 88 b slides ver sliding, which ver at each axial end with a head 87 c, 87 d and 88 c, 88 d is seen, which has a larger dimension than the bore of the corresponding guide block. The axes of the pins 87 b, 88 b are aligned with one another. A located between the guide blocks helical compression spring 87 e, 88 e surrounds the respective pin 87 b, 88 b and is located at one end on the associated guide block 87 a and 88 a and at the other end on the head 87 d between the guide blocks or 88 d. In the position shown in FIG. 13 for the sealing function, the tongue 86 is compressed between the heads 87 d, 88 d which are in contact with opposite sides of this tongue. When the intermediate part 85 is raised, the return spring 87 is compressed and acts to return the intermediate part 85 to its central position. In the opposite direction, it is the return spring 88 which engages while the return spring 87 remains in the stop position.

The longitudinal slot 83 of the connecting rod connecting slide 125 has a lateral groove 89 in the lower part. The longitudinal slot 84 of the intermediate part 85 has at its lower end a further lateral groove 90 or a recess which lies on the same side as the groove 89 .

The intermediate part 85 is provided at one edge with a toothed rack 91 , which cooperates with a pinion 92 with a relatively large diameter, which is mounted in a freely rotating manner about an axis fastened to the frame of the drive rod lock. The connecting rod connecting slide 125 is provided on a neighboring edge with a rack 93 which interacts with a pinion 94 with a smaller diameter, which can rotate about the same axis as the pinion 92 .

The two pinions 92 , 94 are rotatably connected by an angular motion loss system or a rotary dead gear which has a recess 95 which is provided in the cheek of the pinion 92 and has two diametrically opposite arcs with an angular extent of approximately 90 °. The rotary dead gear also has a one-piece driver 96 with the pinion 94 , which has two diametrically opposite, protruding ends, the angle of which is significantly smaller than that of the arches of the recess 95 . The transmission of the rotary movement between the two pinions 92 , 94 takes place in that the driver part 96 comes into abutment at one end of the arches of the recess 95 . If the rotational movement is reversed, the transmission can only take place if the driver part 96 comes into abutment at the other end of the arches of the recess in such a way that the rotational movement is not transmitted within an angular range.

The intermediate part 85 has a shoulder 97 in the vicinity of the cylinder 143 in the upper section which can cooperate with the locking lug 142 when the latter performs the first rotary section of its additional rotation.

The operation of the locking devices I from FIGS . 12 to 14 is explained below, the position corresponding to the open door being shown in FIG. 12.

Based on this, when the door is slammed by the spring 28 , triggered by the release element 19 , ( FIGS. 2 to 5 or FIGS. 6 to 8), the connecting rod connecting slide 125 is caused to move downwards into the position for the sealing function.

During this downward movement, the connecting rod connecting slide 125 is displaced by the rack 93, the pinion 94 and, with it, the driving part 96 in a counterclockwise direction. Characterized in that the return spring 87 presses down, one of the ends of the recess 95 is fixed supported on the driver part 96 , while the intermediate part 85 is moved downward until the tongue 86 rests on the head 88 d.

The intermediate part 85 is then locked against a downward movement, while the connecting rod connecting slide 125 continues its downward movement until it reaches the position shown in FIG. 13. With this additional downward movement of the connecting rod connecting slide 125 , the counterclockwise rotating driver element 96 allows one of the ends of the recess 95 to come into contact with the other end.

The shoulder 97 is in the position to cooperate with the locking lug 142 when it is turned clockwise.

Starting from the position with the sealing function of FIG. 13, the user can reset the spring 28 by appropriate rotation, by ensuring the key that the locking lug 142 makes an additional rotation, as described above.

During the first rotational section of this additional rotation, the locking lug 142 lifts the shoulder 97 , as shown in FIG. 14, whereby the intermediate part 85 is moved upwards. There is a rotational movement of the pinion 92 entrained by the rack 91 in a clockwise direction. The ends of the recess 95 ensure that the driver element 96 and with it the pinion 94 are rotated clockwise. The cooperation of the pinion 94 and the rack 93 causes the drive rod connecting slide 125 to lift.

Due to the diameter ratio of the pinions 92 , 94 , the force to be applied by the user remains acceptable. Due to the different diameters of the pinions 92 and 94 , the intermediate part 85 is raised much faster than the connecting rod connecting slide 125 .

When the locking lug 142 reaches the end of the first rotary section of its additional rotation, the recesses 89 and 90 are at the level of the pin 82 , which is pressed into the two recesses 89 and 90 by the spring 81a . Consequently, the propellant is held Stan genanschlussschieber 125 moving away of the catch 142 from the shoulder 97 against the force exerted by the spring 28 at the beginning of the compression force by the pin 82 and the pin 81st

In the second rotary section of its additional rotation, the locking lug 142 takes the lug 63 of the slide 62 from FIGS. 2 to 5 with it, and the control described above follows. The inclined lower guide 89 a of the groove 89 causes in the upward movement of the drive rod connection slide 125 that the pin 82 comes out of engagement with the groove 90 and is reset as in the longitudinal slots 83 , 84 .
