A lock device of this type is described in EP 2754801 A2. During the blocking, this locking device provides an extension with temporary displacement of the lower locking bar with respect to the upper locking bar. This is essential to prevent the lower locking bar ends from dragging along the floor when the door is retracted into the closed position due to activation of the locking bars through the auxiliary pin. The auxiliary pin is activated when the door is retracted to the closing position in concrete when making a stop with the frame, before the door wing has completely reached the closing position. For the extension of the lower locking bar, document EP 2754 801 A2 provides a complicated mechanism in the mechanics of the lock in the lock housing. The mechanism acts between the lower locking bar connecting device and the upper locking bar connecting device and causes the lower locking bar connecting device to move with time offset after the upper locking bar connecting device in the blocking direction. A lock according to the preamble of claim 1 is known from EP 0571 735 A1.

Figure 1 shows a two-leaf door 1 comprising a passive sheet 2 and an active sheet 3 which are arranged in a hinged door frame 4.

The passive leaf 2 can be fixed by means of an upper and lower switching lock 6, which is arranged on an upper or lower front side, in the door frame 4. The switching locks 6 are connected in actuation by means of locking bars 7 arranged parallel to the vertical longitudinal sides of the passive sheet 2 with a central lock 8, that is, with a device for actuating the lock 8. The lock 8 has a handle 8d that interacts with a mechanical coupling, transforming the mechanical coupling a movement of rotation of the handle 8d in simultaneous pushing movements of the locking bars 7. In the case of the locking bars 7, it is a top locking bar and a lower locking bar. By pressing down on the handle 8d, the locking bars 7 move in the direction of the lock, that is, in the direction of the lock driving device 8, and the switching locks 6, as described below, they unlock In this respect, therefore, the upper locking bar 7 moves downwards and the lower blocking bar 7 moves upwards.

The active leaf 3 has a lock 9 with a handle 9d, the lock 9 also having a lock pin and a bolt. The lock pin and the latch are configured and arranged in such a way that they penetrate into a closing plate provided in the passive sheet 2.

Figures 2 to 8 show the structure of the upper switching lock 6 in detail. Figures 9 to 14 show the functions and working mode of the upper switching lock 6 in detail. The "above" and "below" situation indications selected in the following description in relation to these figures correspond to the assembly situation of the upper switch lock 6. For the lower switch lock 6 these situation indications must be changed.

Fig. 2 shows the upper section of the switching lock 6, the pin 11 entering into a housing in the closing plate 4s in the switching position shown. In this way, the passive sheet 2 is fixed in the door frame 4.

The components of the switching lock

Reference is made to FIGS. 2 to 5. The switching lock 6 has a pin 11, and a bearing support 13 in which the 11 is mounted pivotably. The switching lock 6 further has an auxiliary pin 12 and a switching fork 15. The bearing support 13, the auxiliary pin 12 and the switching fork 15 are movably mounted in the axial direction in the lock housing. 6. In FIG. 2, the switching rod 17 can be recognized. The switching rod 17 is connected to the blocking bar 7 and connected in actuation to the driving device 8.

The pin 11 and the bearing bracket 13

Reference is made to FIG. 2. The switching lock 6 has the pin 11. The pin 11 enters the closing position of the door in a closing plate 4s arranged in the door frame 4.

Refer to Figures 4a to 4c. The pin 11 is pivotally mounted on the bearing support 13. The pin 11 has a through hole 11d for receiving a bearing pin 11z (FIG. 4d) that penetrates a through hole 13d formed in a bearing support 13 (figure 4b) or on a rotating bearing otherwise configured on the side of the bearing support. The bearing support 13 penetrates with its upper end section into a slot-shaped recess formed in the lower end section of the pin 11 (FIG. 4d). The bearing support 13 is urged by means of a return spring, which is not shown in the direction of extension upwards, that is to say away from the drive device 8.

Refer to Figures 5a to 5c. The pin 11 has, in its lower end section, also interlocking recesses 11r opposite each other into which elastic blocking pins 14 interacting with a switching fork 15 (FIG. 5a). The switching fork 15 serves for locking and unlocking the pin 11.

Figure 5b shows the pin 11 in the locked state, in which the locking pins 14 penetrate into the interlocking recesses 11r and, thus, prevent rotation of the pin 11. In this position, the arms of the fork switching 15 push the locking pins 14 into the interlocking recess 11r of the pin 11. In this way, the pin 11 can not be rotated. The locking pins 14 are mounted on the bearing support 13 in a radially displaceable manner. The locking pins 14 interact with a device that moves the locking pins 14 outwardly when the locking pins 14 are out of the action of the arms of the switching fork 15. This device can be controlled by the pivoting movement of the pin. 11. It can be provided that corresponding trailing surfaces or abutment surfaces are configured on the pin 11 and the locking pins 14. The locking pins are thus moved outwardly when the arms of the switching fork 15 do not act on the locking pins 14. Additionally or alternatively, the locking pins can also be urged by means of springs assigned radially outwardly.

Figure 5c shows the pin 11 in the unlocked state, the pin being in a position rotated about its bearing pin 11z and the locking pins 14 not being in action with the interlocking notches 11r. The pin 11 can now rotate. In this rotatable position, the switching fork 15 is displaced downwardly relative to the pin 11. The locking pins 14, with switch fork 15 moved downwards, no longer penetrate into the locking housings 11r of the pin 11. This means that the pin 11 can pivot about the axis of the bearing pin 11z.

The switching fork 15

Refer to figure 4c. The switching fork 15 is formed by a tube having in its upper end section two mutually opposite fork arms 15z with bevelled switching flanges 15f interacting with the locking pins 14 mentioned above. The fork arms 15z are guided in slide guides 13f of the bearing bracket 13.

Refer to Figures 3 and 8a and 8b. In the lower end section of the switching fork 15, two arms 15a are arranged opposite each other, the front surfaces of which face the fork arms 15z form stop surfaces 15a for locking pins 16, as described below. The switching fork 15 can return by means of a return spring 15r (FIG. 3) to a starting situation in which the pin 11 is blocked.

The auxiliary pin 12

As shown in FIG. 3, the auxiliary pin 12 embraces the pin 11. The auxiliary pin 12 has a tubular-shaped body in which the switching fork 15 and the bearing support 13 with the pin 11 are housed. The tubular shape of the auxiliary pin 12 has several grooved grooves that run axially. In the upper end section, the tubular-shaped body has a pin body with a slot-like recess for the passage of the pin 11. The tubular-shaped body of the auxiliary pin 12 is formed by several parts. It consists of an upper section 12o and a lower section 12u.

To facilitate assembly, the lower section 12u of the auxiliary pin 12 is formed by two halves. The assembled tubular body of the auxiliary pin 12 is urged by means of a return spring, not shown in the figures in an upwardly extending direction, that is to say, away from the actuating device 8. The function of the pin is described below. Auxiliary: Refer to Figure 2: The auxiliary pin 12 detects whether the door leaf is in closed or open position. In the position shown in FIG. 2, the auxiliary pin 12 makes contact with the closing plate. In this position, the auxiliary pin 12 is partially retracted in the switching lock 6 and the closing plate 4s prevents it from extending to its fully extended position.

The auxiliary pin 12 serves, moreover, to lock and release the switching fork 15. As can be seen in figure 3, the auxiliary pin 12 has a control curve 12s in its lower section which serves for the displacement of locking pins 16. The locking pins 16 are controlled by the control curves 12s formed in the lower section of the auxiliary pin 12 in slot-shaped recesses. The control curves 12s have two linear sections of different height aligned with the longitudinal axis of the auxiliary pin 12 which are connected by an obliquely running switching section. The locking pins can be moved by means of the control curves 12s of the auxiliary pin in such a way that the locking pins 16 penetrate the path of movement of the switching fork 15 and oppose a movement of the switching fork 15. upwards. In FIG. 3, the release position in which the locking pins 16 do not penetrate the path of movement of the switching fork 15 is shown. In FIG. 14, the blocking position is presented: In this case, the it can recognize the locking pin 14 with which an arm 15a of the switching fork 15 makes contact. By contacting the arm 15a of the switching fork 15 on the locking pin 16, movement of the switching fork is prevented. 15 in this case upwards. This means that in this position the pin 11 can pivot.

The switching rod 17

The switching rod 17 is shown only in FIG. 7b. The switching rod is in actuation connection with the actuation device of the lock 8 (FIG. 1). As shown in FIG. 7a, the switching rod 17 passes through the switching fork 15. The upper end section of the switching rod 17 has a recess 17a in which a transverse pin is inserted (FIG. 7b). This transverse pin interacts with the switching fork 15. When the switching rod 17 is retracted, the switching fork 15 is driven in such a way that the switching fork 15 is moved away by the pin 11. The switching rod has a groove of perimeter lock 17r. In this locking groove, locking elements 19 can penetrate (see FIGS. 7 a and 7 b) which prevent a movement of the switching rod 17 upwards. The interlocking elements are described in more detail below.

The bearing element 18

Figures 6a and 6b show a bearing element 18. The bearing element 18 composed of two halves has first guide notches 18e in which an elastic locking element 19 is guided by means of a spring not shown in the figures . The locking element 19 interacts with a peripheral locking groove 17r which is formed in a switching rod 17 (see figures 7a and 7b). The enervating element 19 is controlled by a control curve 15s formed in the lower section of the switching fork 15 (see Figure 4c). The control curves 15s have two linear sections of different height aligned with the longitudinal axis of the switching fork 12 which are connected by an obliquely running switching section.

The bearing element 18 also has two guide sipes 18fz in which an elastic locking pin 16, previously described in FIG. 3, is guided.

Figures 9 to 14 show different operating states of the switching lock 6.

Figure 9 shows the switching lock 6 with pin 11 blocked. The switching rod 17 connected to the upper blocking bar 7 assumes its upper position.

Figure 10 shows the switching lock 6 with pin 11 unlocked. The switching rod 17 connected to the upper blocking bar 7 assumes its lower position.

Figure 11 shows the switching lock 6 with pin 11 unlocked and inclined.

Figure 12 shows the switching lock 6 with pin 11 inclined and retracted in the housing of the switching lock 6.

Figure 13 shows the switching lock 6 with retracted pin 11 and auxiliary pin 12 extended, and figure 14 shows the switching lock 6 with extended pin 11 and auxiliary pin 12 extended.

Next, the mode of operation of the switching lock 6 will be explained with the help of the aforementioned figures 9 to 14. In this sense, in FIG. 9, the switching lock 6 is shown with a passive leaf blocked. Figure 14 shows the switch lock 6 with fully open passive leaf. In figures 10, 11, 12 and 13, the switching lock 6 is shown in different stages during the opening of the passive sheet 2.

The locked position locked in figure 9 / end position

Figure 9 shows the switching lock 6 with passive sheet 2 blocked. The switching rod 17 connected to the upper locking bar assumes its upper position. The pin 11 is fully extended and penetrates into a latch housing associated with it, not shown, of the closing plate in the door frame. The auxiliary pin 12 is only partially extended. A complete extension of the auxiliary pin 12 is prevented by a closing plate, not shown, arranged in the door frame. In addition, the switching fork 15 is in its upper position, the fork arms 15z pushing the locking pins 14 into the interlocking recesses 11z and thus preventing a rotation of the pin 11. This position of the pin 11 in the fork of switching 15 is shown in figure 5b. The pin 11 is rigid in this position, ie rigid to rotation and / or non-pivotable, since the switching fork 15 holds the pin 11 by means of the locking pins 146 in its rotated position shown.

The intermediate position in figure 10

Figure 10 shows the switching lock 6 after actuation of the lock actuation device 8. The actuation can be carried out manually by a handle 8d. However, it is also possible for the drive device to be driven by motor. If the lock 8 is actuated, the locking bar 7 moves in the direction of the lock 8. The switching rod 17, which is connected to the upper locking bar 7, is also retracted in this direction in the direction of the lock 8. In the exemplary embodiment shown, the switching rod 17 is designed as the upper section of the blocking bar 7. In the retraction of the switching rod 17 in the direction of the lock 8, the switching fork 15 is also moved by the rod. of switching 17. The pin 11 remains in its fully extended position. As the switching fork 15 is retracted, the fork arms 15z are out of the action with the locking pins 14. The locking pins 14 no longer penetrate into the locking recess 11r of the pin 11. In this way, it is suppressed the locking of the pin 11. The pin 11 is not rigid in this position, ie it can pivot, since the switching fork 15 is at a distance, ie out of reach of the locking pins 14.

In the retracted state of the switching rod 17, the locking element 19 supported on the rolling element 18 enters the locking groove 17r of the switching rod 17. The locking element 19 keeps the switching rod 17 in its retracted position inside or next to the bearing element 18 fixed on the blade and prevents a movement of the switching rod 17 towards the pin 11. The passive blade 2 is no longer locked in this position and can be opened by pushing. In the position shown in Figure 10, the auxiliary pin 12 is partially extended, the extension of the auxiliary pin 12 is produced by solicitation by means of a spring not shown and is limited by the closure plate not shown in figure 10.

The intermediate position in figure 11

Figure 11 shows the switching lock 6 during the opening of the passive sheet 2. The positions of the auxiliary pin 12, of the switching fork 15, of the locking element 19 and of the switching rod 17 have not been modified with respect to the position shown in figure 10. Only the pin 11 is pivoted, which is caused by impact of the pin 11 on the edge of the latch housing of the closing plate on the side of the door frame when pushing the passive sheet 2. pin 11 is no longer rigid in this switching position, since the pin 11 assumes a pivoting position in which the locking pins 14 do not penetrate the locking recesses of the pin 11r. In this pivoting position, the pin 11 remains pivotable regardless of the position of the switching fork 15.

The intermediate position in figure 12

Figure 12 shows the switching lock 6 in another position during the opening of the passive sheet 2. The positions of the auxiliary pin 12, of the locking element 19 and of the switching rod 17 have not been modified with respect to the positions shown in FIGS. Figures 10 and 11. In Figure 12, the pin 11 makes contact in the closing plate on the side of the door frame and no longer penetrates into the latch housing of the closure plate. By contacting the pin 11 in the closing plate, the bearing support 13 with the pin mounted thereon is displaced against the effect of the spring 13r, in the direction of the actuating device 8 downwards. The switching fork 15 is displaced from the position shown in FIGS. 10 and 11 further downwards. The displacement of the switching fork 15 takes place because the locking pins 14 mounted on the bearing support 13 make contact on the upper sides of the switching arms 15 of the switching fork 15 and a displacement of the support is caused. bearing 13 downwards and, therefore, a displacement of the switching fork 15 downwards. It should be noted that the switching fork 15 in the position shown in FIG. 12 can not force the locking pins 14 into the locking housings of the pin 11, since with the pin 11 pivoted, the locking housings 11 do not they align with the bearing 13a of the locking pins 14. This means that the pin 11 in the position shown in FIG. 12 is pivotable and can not be fixed. The pin 11 remains in the same position as in figure 11, in which the pin 11 is not fixed by the switching arms 15z.

The intermediate position in figure 13

Unlike figure 12, the auxiliary pin 12 no longer makes contact in figure 13 in the closing plate and is displaced under the effect of the spring that requests it completely upwards. The displacement of the auxiliary pin 12 upwards in its fully extended position causes the locking pins 16 mounted on the bearing element 18 fixed on the blade to be displaced by the control edge 12s of the auxiliary pin 12, so that the pins 16 are engaged in the movement zone of the switching fork 15, since the locking pins 16 are still required by the inclination of the control edges 12s.

Figure 13 shows the switching lock 6, therefore, in another position during the opening of the passive sheet 2. The positions of the locking element 19 and of the switching rod 17 have not been modified with respect to the positions shown in the figures 10 and 12. The pin 11 also continues to make contact in the closing plate of the door frame side, in such a way that the position of the pin 11, of the bearing support 13 and of the switching fork 15 have not been modified in to the position shown in figure 12. Only the auxiliary pin 12 no longer makes contact with the closing plate.

The unlocked open position / final position

Figure 14 shows the switching lock 6 in its position with passive sheet 2 open. In this position, the pin 11 also does not contact the closing plate on the side of the door frame and is fully extended, and the pin 11 is in its non-rigid rotationally pivotable position. A spring 15r is associated with the switching fork 15, which is supported on the bearing element 18 fixed on the blade and urges the switching fork 15 in the direction of the extended position of the associated pin 11. A spring 13r is associated with the bearing support 13, which also rests on the bearing support 18 fixed on the leaf and requests the bearing support 13 in the direction of the extended position of the associated pin 11. Under the effect of the spring 13r not shown, the bearing support 13 is forced together with the pin mounted therein to its fully extended position. The switching fork 15 is forced by the effect of the spring 15r upwards. When the locking pins 16 enter the movement zone of the switching fork 15, the extension of the switching fork 15 is limited upwards. The locking pins 16 make contact in this direction on the abutment surfaces 15a of the switching fork 15, so that extended auxiliary pin 12 prevents further movement of the switching fork upwards and the switching fork 15. it is maintained by the locking pins in a central position. In the open position of the passive leaf shown in Figure 14, the position of the enervation element 19 and of the ^control rod ¹⁷ remains unchanged ^{with respect to the position shown in figures 10 to 13. The element of}

a locking groove 17r of the control rod, by which r ^{vamiento 19 still} contacts in the control rod l is maintained in its retracted position.

Next, the processes of passing the switching lock 6 from the open position of the passive sheet 2 to the locked position of the passive sheet 2 are explained.

Starting point is the position represented in figure 14, which shows the switching lock 6 with open passive leaf. In this regard, both the auxiliary pin 12 and the bearing support 13 with the pin 11 mounted therein are in their fully extended position. The switching fork 15 is maintained by means of the locking pins 16 remote from the pin 11. The switching fork 15 is not in action with the pin 11. This means that the pin 11 can be tilted. In addition, the locking element 19 makes contact in the locking groove 17r of the control rod 17, by means of which the control rod 17 is held in its retracted position. When the passive sheet 2 is closed, the pin 11 abuts the closing plate (FIG. 13) first. In this way, the pin 11 pivots first. The positions of the switching fork 15, of the bearing support 13, of the auxiliary pin 12 and of the control rod 17 remain unchanged. This position of the switching lock 6 corresponds to the position shown in FIG. 14 with the difference that the pin 11 is pivoted towards the auxiliary pin. When continuing to close the passive sheet 2, the bearing support 13 with the pin 11 mounted thereon is retracted in the switching lock 6. In the subsequent development of the closure of the passive sheet, also the auxiliary pin 12 abuts the sheet (Fig. 12) and is retracted together with the bearing support 13 and the pin in the switch lock 6. This position of the switch lock 6 corresponds to the position shown in Figs. 12 and 12a with the difference of that the pin 11 is pivoted towards the auxiliary pin. By retracting the auxiliary pin 12, the control curves 12s stop contacting the locking pins 16 (see FIG. 12a). The locking pins 16 are returned by springs not shown radially outward to their starting position. This means that, with auxiliary pin 12 partially retracted, the locking pins 16 no longer make contact with the stop surfaces 15a of the control fork 15 and the control fork 15 is no longer impeded in its upward movement. The control fork is then spring loaded and forced in the direction towards the pin 11. In the upward movement, the switching arms 15z reach the locking pins 14 and force the locking pins 16 into the interior of the housing. interlocking 11d of the pin 11. In this way, the pin 11 is fixed in relation to the pin support 13, ie, it can no longer pivot.

As soon as the passive leaf 2 has reached its closing position, the pin no longer makes contact with the closing plate. Under the spring effect, the control fork 15 or the bearing support 13 with the pin 11 fixed thereon are brought to their fully extended positions. This blocking position is shown in FIG. 9. In the movement of the control fork 15 to its extended position, the control curve 15s makes contact with the locking element 19. The locking element 19 is thereby moved in the direction radially outwardly, outside the interlocking groove 17r of the control rod 17. The control rod 17 and the locking bar 7 engaged in the control rod 17 are no longer fixed by the locking element 19. The bar Lock 7 can also scroll up.

Essential in the switching lock 6 of the present invention is that the switching rod 17 and, therefore, the locking bar 7 engaged therein, only are not fixed by the locking element 19 when the switching fork is shifted towards above. The switching fork, however, can only move upwards when the auxiliary pin 11 is partially retracted by means of the closing plate in the switching lock 6 and the closing plate prevents its extension.

The upper and lower locking bars 7 and 6 are coupled together by a mechanical coupling of the lock 8, ie by a mechanical coupling of the lock actuation device 8. This means that the lower locking bar 7 can only extending inside the notch of the base side when the locking element 19 no longer enters the interlocking groove 17r of the control rod 12 and, therefore, has released the control rod. As shown above, the locking element 19 is displaced by the control curve 15s of the switching fork 15 in such a way that the switching fork can be fully extended when the pin 11 is extended in the frame side housing. of door.

In addition, a compensation of the gravity force of the components is provided on the pin of the lower locking bar by spring-loaded vertically upwards, so that the pin 11 without solicitation by means of the locking bar does not extend down by itself driven by the force of gravity. The extension stroke of the auxiliary pin 12 is essentially limited already by stop.

In a particularly preferred variation of the illustrated embodiment, it is provided that the upper locking bar is engaged by means of a spring in the locking direction and that the auxiliary pin interacts with the upper locking bar in such a way that the upper locking bar Stay in your unlocked position while the closing position of the blade is not reached, and that the upper locking bar is connected to the lower locking bar by means of a coupling mechanism that unites the two locking bars for a forcibly movement in the opposite direction.

By controlling the pin 11 of the lower locking bar by means of the upper switching lock 6, it is achieved that the pin 11 of the lower locking bar does not cause any damage to the floor of a space with open passive sheet 2 it can travel through the door 1. On the other hand, the lower locking bar is retracted in spite of the handle 8d pressed from the passive leaf 2, as shown in figure 13, and only extends again when the pin 11, when closed the passive sheet 2 is completely extended in the closing plate 4s in the housing on the side of the door frame.

In preferred embodiments, such as, for example, in the exemplary embodiment shown in the figures, it is provided that the actuating device 8 acts by means of a handle 8b or by means of a motor drive not shown on the pin 11 alone. in the sense of unlocking the lock, ie only to move the pin 11 to the unlocking position or to release at least the pin 11 so that it can be moved to the unlocking position. The locking of the lock is carried out automatically, that is to say that the pin 11 is self-locking without the need for a manual actuation or motor drive of the actuating device 8. In the case illustrated in the figures, the locking is automatically carried out as soon as possible. as the leaf is brought to the closing position and, in this respect, an actuation of the auxiliary pin 12 and a driving of the pin 11 is effected by means of a stop in the frame and / or in the closing plate. In the illustrated embodiment, the two conditions mentioned for the development of the block are required. In modified embodiments, as also explained in relation to the exemplary embodiments, an auxiliary pin drive can also be provided as the sole condition for the development of the block.

In Figure 15 another embodiment of a lock is shown. This lock coincides with the previously described lock a pin 11 mounted pivotably on a bearing body 13, a switching element 15 and an auxiliary pin device 12. The essential difference with respect to the lock of figures 1 to 12 is that the lock according to FIG. 15 has a clamping ring 20 for locking the latch control element 17 and, in addition, an adjusting element 29. The clamping ring 20 and the adjusting element 29 are described then.

The tightening ring

The clamping ring 20 is movably mounted in the lower region opposite to the pin 11 of the housing body 6g in the form of a bushing. The tightening ring 20 essentially has the design of a hollow cylinder. The clamping ring 20 has a projection with which the clamping ring 20 is mounted in a groove 6gs in the housing body 6g in a torsionally secure manner.

Above the clamping ring 12, the auxiliary pin device 12 is disposed movably in the housing body 6g. The auxiliary pin device 12 is supported at least by sections in the clamping ring 20. The clamping ring 20 and the auxiliary pin device 12 are urged by a helical pressure spring 20r in the direction towards the pin 11. The spring helical pressure 20r is supported on a support ring 20rs. The support ring 20rs has three projections with which the support ring 20rs can be inserted fixedly in the housing in the housing body 6g. For this, the housing body 6g has three corresponding insertion housings 6ge for the support ring 20rs.

The pin control element 17 passes through the clamping ring 20 from below coaxially through the coil spring 20r and the support ring 20rs. The auxiliary pin device 12 rests on the upper side of the clamping ring 20 ab.

In the closing position of the door, the auxiliary pin device 12 is driven by the frame, preferably by a closing plate mounted on the side of the frame and, thereby, the clamping ring 20 is displaced by the pin device auxiliary 12 against the effect of the helical pressure spring 20r towards the lower end of the housing body 6g. In this position, the axis of the clamping ring 20 with hollow cylindrical shape is aligned with the axis of the latch control element 17. In this position, the latch control element 17 is only embraced by the clamping ring 20, being present a certain clearance between the outer diameter of the latch control element 17 and the inner diameter of the clamping ring 20. The latch control element 17 can move freely without being held in this position by the clamping ring 20.

If external forces do not act on the auxiliary pin device 12, the auxiliary pin device 12 and the clamping ring 20 are urged by the force of the helical pressure spring in the direction towards the pin. On one of its sides, the clamping ring 20 is held by its projection at the upper end of the groove 6gs of the housing body 6g. On its opposite side to the projection, the clamping ring 20 is displaced upwards due to the force of the helical pressure spring 20r. In this position, the clamping ring 20 tilts towards the latch control element, ie the axis of the clamping ring 20 with hollow cylindrical shape no longer aligns with the shaft of the latch control element 17. The latch control element 17 is fixed by the clamping ring in tightening action, in such a way that the latch control element 17 is fixed immovably with auxiliary pin device 12 extended .

Depending on the position of the auxiliary pin device 12, the latch control element 17 is controlled by means of the clamping ring 20. With auxiliary pin device 12 applied on the side of the frame, as is the case with door leaf closed, the latch control element 17 can move freely. With the door leaf open, when the auxiliary pin is extended, the extension of the latch control element 17 to the pin is prevented.

The adjustment element

The adjusting element 29 is inserted in the end of the pin side of the latch control element 17. The adjustment element 29 has at its end opposite the latch control element 17 an extended head which serves to interact with the latch element. switching 15. In this regard, it is essential that the adjustment element 29 can be inserted in relation to its depth in a variable manner in the latch control element 17. By this it is meant that the head of the adjustment element 29 protrudes over the pin end of the latch control element 17 more or less preferably variably adjustable. It can be provided that the adjusting element 29 has an external thread and the latch control element 17 is provided at its end on the pin side with an internal thread. In this regard, the height with which the head of the adjusting element 29 projects over the latch control element 17 by means of a corresponding thread can be adjusted in a variable manner. Alternatively, it can be provided that the latch control element 17 has a plurality of locking housings, so that the adjustment element 29 can be inserted at a different height in the latch control element 17.

The operating mode of the latch control element 17 and the adjustment element 29 is as follows. By actuating the driving device 8 by means of a lever or a motor drive device, the latch control element 17 is moved together with the adjusting element 29 fixed thereon away from the pin 11 and towards the switching element 15. In the In the development of this movement, the head of the adjusting element 29 reaches a trailing edge of the switching element 15, so that in this respect the switching element 15 is driven by the adjustment element. By distancing the switching element 15 from the pin 11, the pin 11 is brought into its pivotable position, since the fork arms of the switching element 15 are released from the action of the locking pins.

As the adjusting element 29 can be inserted at variable depth into the latch control element, it can be adjusted if, in the case of actuation of the actuating device 8, the switching element 15 is carried away immediately or after a certain actuation stroke of the actuator. latch control element 14. If the switching element 15, in the event of actuation of the actuating device 8, is immediately dragged by the latch control element 17 or in the course of the actuation stroke of the control element of the latch control element 17, the latch control element 15 latch 17 depends on how the lock should be used.

If the lock is used as a top closure on a dormant leaf of a two-leaf door, it can be provided that the lock interacts with a bolt / dead bolt lock of the dormant leaf. In such a use of the lock, it is important that the locking position of the lock pin 11 can be suppressed after the pins / latch bolt ejectors have been actuated. In this case, in the assembly of the lock, the adjustment element 29 is inserted in the latch control element 17 in such a way that in the blocking position of the lock there is a relatively large distance between the head of the adjustment element 29 and the switching element 15.

In the use of the lock as a top closure in a one-leaf door, it is desirable that the locking position of the pin 11, ie, the non-pivotability of the pin 11, be eliminated immediately upon activation of the driving device 8. In this In this case, in the assembly of the lock, the adjustment element 29 is inserted in the latch control element 17 in such a way that in the blocking position of the lock there is as small a distance as possible between the head of the adjustment element 29 and the switching element 15. This means that the adjusting element 29 is inserted in a very deep way in the latch control element 17.

With regard to the locking process, in the exemplary embodiment shown in FIG. 15, it is provided that the pin 11 interacts with the auxiliary pin device 12 and / or the latch control element 17 in such a way that the pin 11 can be carried and / or freely switched by a drive on the side of the closing plate of the auxiliary pin device 12 to its locking position without requiring a drive on the side of the closing plate of the pin 11.

In this regard, it is provided that the release device is configured as a clamping device 20 which interacts with the latch control element 17 and / or the pin 11, and

that the auxiliary pin device 12 interacts directly with a release device of the latch control element 12 and / or of the pin 11.

In the exemplary embodiments shown in the above Figures 2 to 14, unlike the present case, it is provided that the pin 11 interacts with the auxiliary pin device 12 and / or the latch control element 17 in such a way that the pin 11 it can be carried and / or released to its blocking position when a drive has been made on the side of the closing plate of the auxiliary pin device 12 by retraction of the auxiliary pin device 12 and a drive on the side of the closing plate of the auxiliary pin. pin 11 by pivoting the pin 11.

Figure 16 refers to a variant embodiment in which the pivoting pin 11 is urged by means of a spring 11f to the pivoting position shown in figure 16. This pivoting position is designated in the following as the first position of pivoting. Figure 16 shows only the assembly of the pin 11 with the spring 11f modified in this embodiment. This is the construction group shown for the previous embodiment of Figure 4d. The remaining structure and functions of the modified embodiment correspond to the embodiment of FIGS. 1-15.

The spring 11f is designed as an arm spring. It rests on the bearing body 13 ab, by penetrating a bearing bolt 13z, which is inserted in the bearing body 13, into a receiving hole in one of the arms of the spring 11f, the other arm of the spring penetrates into an orifice of accommodation 11th in the pin 11.

The only functional difference of this variant embodiment with respect to the previous embodiment only consists in that the pivoting pin 11 is pivoted by the spring 11f in each case to the first pivoting position, so that, in the open position of the door 1, the pin 11 adopts this first pivoting position and in such a way that also in the closing position of the door the pin 11 assumes this first pivoting position. This first pivoting position also occurs when the door passes from the open position to the closed position and the pin 11 abuts its inlet tilt in the frame, and the pin is retracted in this respect also in the direction of extension of the frame. the locking bar on the door leaf.

The second pivoting position against the effect of the spring 11f is only maintained provisionally when the locking bar 7 operated by the handle 8d (see figure 1) releases the pivotability of the pin 11 and, during this actuation of the handle 8d, the pin 11 pivots, when the door is opened by means of a stop on the frame, to the second pivoting position and the pin is retracted by a displacement in the direction of extension of the locking bar on the door leaf. Immediately upon reaching the closing position of the door, the pivoting pin extends and is returned by the spring 11f to the first pivoting position.

This return of the pin 11 of the second pivoting position to the first pivoting position and the extension of the pin are effected each time the stop position between pin and frame is suppressed. This is the case when the door has been moved from the closed position to the open position. However, this is the case when the pin and frame stop position, which occurs in the closed position when the door is requested in the opening direction, is still deleted in the closed position and the door leaf remains in the closed position. closing position. In this case, the pin 11 is pivoted back by the spring 11f to the first pivoting position.

The spring loading of the pin 11 with the door open has the consequence that, in the open position of the door, the pin 11 is always in the first pivoting position. In this sense, the pin 11 is in a position in which the pivotability of the pin 11 can not be blocked by the switching fork 15. The pin 11, in this sense, can not be blocked by the switching fork because the fork 15 with an open door, as in the previous embodiment, is held by the locking pins 16 in their position that does not block the pin 11, which has been carried by the unlocking drive when the door is opened and the switching fork 15 out of reach of the action with the pin 11. Only in the closing position of the door is the switching fork 15, by the effect of the auxiliary pin 12, out of the reach of the action of the pins lock 16. In this switching position, the switching fork 15 locks the pin 11. This locking is effected when the pin 11 is in the first pivoting position. The spring 11f acts on the pin 11 as already explained, the spring 11f requesting the pin both in the closed position and in the open position of the door to the first pivoting position. This means that in the closing position of the door, in which the switching fork 15 is in its position that blocks the pivotability of the pin, the pivotability of the pin 11 is blocked by the switching fork 15. This brings with it the advantage that malfunctions which occur when, with spring 11f not present, in the closing position of the door after an unlocking of the switching fork 15 by actuation of the locking bar 7, the pin 11 has been brought to its second pivoting position. The second pivoting position of the pin 11 is produced by abutting the pin in the frame when the door is requested in the closed position in the opening direction.

In case the spring 11f is not present, this second pivoting position of the pin 11 would also remain, even if the door is not opened subsequently, but the pin 11 stops abutting the frame and the door remains in the closed position. In case the spring 11f is not present, the pin 11 would attack with its second pivoting position and in the housing on the side of the frame. Since, however, the pin in the second pivoting position can not be blocked by the switching device, in this case the pin 11 does not it would be blocked, that is, it would be in a position of no extended blockade. By means of the pin 11f according to the invention a dysfunction of this type is avoided.

A particular advantage in the lock is that, in the case of an open door leaf, the lock is secured against manipulation by manual pressure of the auxiliary pin 12 and / or of the pin 11. This means that, by means of pressure of the auxiliary pin 12 and / or the pin 11 with open door leaf does not trigger an extension of the lower locking bar. The control rod 17 coupled in motion with the lower locking bar is in any case held by the locking elements 19. In the illustrated embodiment, in these cases the pivotability of the pin 11 is also released simultaneously and, therefore, the pivotability is not blocked.

With the door leaf open, the bearing support 13 with the pin 11 mounted on it and the auxiliary pin 12 are in their respective positions extended outside the lock. The switching fork 15, however, is held by the locking pins 16 in their retracted position, the locking pins 16 contacting the locking surfaces 15a of the switching fork 15. This means that the pin 11 can pivot. freely, since the switching fork 15 is in its retracted position and, therefore, out of reach of the action with the pin 11, that is, the blocking elements 14 do not block the pivotability of the pin 11. With blade of the open door, the control bar 17 is also blocked by the interlock elements 19.

In the following, it is stated that, with open door leaf, in case a) by single manual pressure of the auxiliary pin 12 or in case b) by joint pressure of pin 11 and auxiliary pin 12, the blocking of the lock. Only in case c) the locking of the lock occurs, that is to say when, with auxiliary pin 12 pressed and pin 11 pressed at the same time, then the pin 11 is released while the auxiliary pin 12 remains in its activated pressed position. .

Regarding a) Single pressure of the auxiliary pin with open door leaf

If, with the door leaf open, the auxiliary pin 12 is pressed manually inside the lock, the control curves 12s of the auxiliary pin 12 are no longer in contact with the locking pins 16. The springs, not shown, are requested by the locking pins 16 to their position releasing the switching fork 15, however, can not move the locking pins 16. This is because the switching fork 15 is spring-loaded in the extension direction by the spring 15r and the force of the spring 15r acts by means of the stop surfaces 15a of the switching fork 15 on the locking pins 16. This means that the force of the spring 15r is absorbed by the locking pins 16.

Due to the static friction that appears between the abutment surfaces 15a of the switching fork 15 and the locking pins 16, the locking pins 16 can not move. The force of the springs, not shown, which attempt to request the locking pins 16 to their position releasing the switching fork 15, is not sufficient to overcome the static friction that occurs between the stop surfaces 15a of the switching fork 15 and locking pins 16 due to spring 15r. In this way, the switching fork 15 is secured in its retracted position even when, with the door leaf open, the auxiliary pin 12 is pressed. When the switching fork 15 is held in the retracted position, the switching fork 15 does not come into contact with the locking elements 19, which in the case of contact would cause a release of the control rod 17 and an extension of the lower locking bar. Moreover, in this position, the arms of the switching fork 15 do not come into operation with the locking elements 14. This has the consequence that the pivotability of the pin 11 is maintained.

Regarding b) Joint pressure of pin and auxiliary pin with open door leaf

If, with the door leaf open, the auxiliary pin 12 and also the pin 11 are pressed manually into the interior of the lock, the control curves 12s of the auxiliary pin 12 are not in contact with the locking pins 16. Simultaneously, the switching fork 15 is also moved with pin 11 pressed into the lock interior, in such a way that the stop surfaces 15a of the switching fork 15 stop contacting the locking pins 16. The locking pins 16 are displaced by means of locking pin springs not shown to their position released by the switching fork 15.

When the auxiliary pin 12 and also the pin 11 are released, that is, when they stop pressing, the next development occurs. The auxiliary pin 12, the switching fork 15 and the bearing support 13 on which the pin 11 is mounted are each required by means of a spring associated in the extension direction. In this joint extension movement of auxiliary pin 12, switching fork 15 and bearing support 13 first stop the control curves 12s of the auxiliary pin 12 with the locking pins 16, by means of which the locking pins 16 are displaced to their position blocking the switching fork 15. In the further development of the auxiliary pin extension movement 12, the switching fork 15 and the bearing support 13, the abutment surfaces 15a of the switching fork 15 meet the locking pins 16, whereby the subsequent movement of The extension of the switching fork 15 is stopped and by means of which the switching fork 15 is maintained in a retracted position.

Only the auxiliary pin 12 and the bearing support 13 with the pin 11 mounted thereon can reach their fully extended positions.

Also in this case, the switching fork 15 is maintained in a retracted position and does not make contact with the locking elements 19, which in the case of contact would cause a release of the control rod 17 and an extension of the control bar 17. lower block. Moreover, in this position, the arms of the switching fork 15 do not come into operation with the locking elements 14. This has the consequence that the pivotability of the pin 11 is maintained.

Regarding c) Joint pressure of pin and auxiliary pin with open door leaf with subsequent release of the pin keeping the auxiliary pin pressed

As already explained in relation to case b), the control curves 12s of the auxiliary pin 12 with the locking pins 16 are no longer in contact, if the auxiliary pin 12 and also the pin 11 are pressed into the interior of the lock. Since the switching fork 15 together with the pin 11 are displaced inside the lock, the stop surfaces 15a of the switching fork 15 cease to make contact with the locking pins 16. The locking pins 16 are displaced by means of locking pin springs not shown in their position which releases the switching fork 15.

When they release the pin 11, that is, when it is no longer pressed, while the auxiliary pin 12 remains in its pressed position driven towards the inside of the lock, the following development takes place: The switching fork 15 and the bearing support 13, on which the pin 11 is mounted, are requested in each case by means of a spring associated in the extension direction. Since the auxiliary pin, however, remains in its depressed position, the control curves 12s of the auxiliary pin 12 are no longer in contact with the locking pins 16, ie, the locking pins 16 remain in their position that the switching fork 15 is released. Accordingly, the switching fork 15 and the pin 11 can be completely extended outside the lock by means of associated springs in each case. In this sense, the arms 15z of the switching fork 15 come into contact with the locking elements 14 mounted on the bearing support 13. By means of the action of the arms 15z, the locking elements 14 are moved into the notches. 11d of the pin 11. In this way, the pin 11 can no longer pivot. The pin 11 now adopts its locked position, in which the pin 11 is fully extended outside the lock housing and is locked in its pivotability.

As the switching fork 15 extends, in addition, the switching flanks 15s of the switching fork 15 come into operation with the locking elements 19. The locking elements 19 are displaced in this direction in the radial direction away from the control rod 17, in such a way that the locking elements 19 stop penetrating into the slot 17r of the control rod 17. In this way, blocking of the blocking rod 17 is suppressed. The control rod 17 thus moves. upwards and the lower locking bar coupled with the control rod moves to its extended position which locks the leaf. With respect to the embodiment of the figures, embodiments are also provided with variations in which a lower locking bar 7 is not present. This means that the locking of the door takes place exclusively in the area of the upper frame. Functions a), b) and c) are present in the same way. Locking and releasing the locking bar refers only to the upper locking bar, since there is no lower locking bar.

In another modified embodiment with respect to the figures, a pin 11 can be used that is not pivotably configured about an axis perpendicular to the direction of extension of the locking bar, but is configured relatively movable with respect to the locking bar only in the direction of extension of the locking bar. In this embodiment, the functions described above a), b) and c) have varied in such a way that only the blocking bar is blocked or released as in a), b) and c). As regards the actuation of the pin, actuating the pin means retracting or keeping the pin retracted. Constructively, simplifications are obtained in the exemplary embodiment with non-pivotable pin 11. The components that affect the pivoting assembly and the pivotability control can be suppressed or simplified accordingly.
