Description

The invention relates to a locking device according to the preamble of claim 1.

Locking devices of this type are already known. From the DE 3203319 A1 For example, a locking device is known which has two drive rods and a pinion effective between the drive rods. The drive rods are guided along the Flügelfalzes in a Beschlagaufnahmenut and are provided along a partial length with a toothing, in which engages the pinion. The pinion is mounted stationary in a housing and engages diametrically in the serrations of the drive rods. If a drive rod is moved, so does the pinion permanently engaged with the drive rods and moves the second drive rod in a direction opposite to the direction of movement of the first drive rod direction. This thrust reversal is used, for example, to move at a displaced in the locking movement upward drive rod attached to the lower edge of the wing bolt down into a locking engagement. It is exploited that the two drive rods perform essentially the same stroke.

From the DE 10111903 B4 It is known to apply this principle to different spars in locking pins.

In order to change the movement of the abortive drive rod in its travel it is from the DE-PS 1244611 known to apply a so-called climbing gear. The pinion is movable and is displaced by means of a slide, which is associated with a toothing a drive gear. The pinion is assigned a stationary mounted teeth in a housing, so that the pinion rolls on the stationary teeth. Diametrically to the stationary toothing a toothing of a movably mounted in the housing drive rod is mounted. By forming a Momentalpols on the fixed teeth is a translation that is dependent on the diameter of the pinion. Again, the direction of movement is equal to the direction of movement of the slider. Similar embodiments are from the DE-PS 1292034 or the EP 0534089 B1 known.

A disadvantage of all mentioned embodiments, it is therefore that the movement is always linear to the drive member. In some cases, however, it is desirable for the movement of a drive element-preferably a drive rod carrying a locking element-to run counter to a partial lift and otherwise to be rectified.

To achieve this object, the invention provides that the connection of the pinion and the drive rod via a coupling rod. The coupling rod is articulated as a compound of the pinion to the abortive drive rod eccentrically on the pinion. Thus, there is a partial overlap of the coupling rod and the pinion, resulting in an oscillating movement of the abortive drive rod. The concept is space-saving and suitable with a simple structure for use in a drive rod fitting part.

It is further provided that the coupling rod is articulated to a flat surface of the pinion, so that can be realized on the ratio of the pitch circle and the distance of the pivot point from the pivot point of the pinion Hubveränderung.

Thus, the load on the pinion via the coupling rod is symmetrical, the coupling rod consists of two parallel guided rods, which are connected on both sides of the pinion on the flat surface.

It is also advantageous if the coupling rod consists of a slide, in which a projecting from the flat surface of the pinion pin dips into a backdrop. The slider thus combines the drive rod and the coupling rod in one component.

It is expedient that the backdrop is perpendicular, so that the slide has a maximum stroke.

It is also contemplated that the slider surrounds the pinion U-shaped, so that the pinion is loaded symmetrically and the leadership of the pin is ensured in the backdrop of the slider.

Another embodiment provides that the pinion consists of two parallel pinion disks and the storage is carried out by a U-shaped bracket on the outside of the pinion disks. As a result, the storage can be simplified and the obstruction of the coupling rod is excluded. It can also be provided as a kinematic reversal that the bearing of the pinion takes place on the outer surfaces and the coupling rod between the two pinion disks is mounted.

A particularly advantageous embodiment provides that the drive rods are part of a Treibstangebeschlages for a window or door and each drive rod carries at least one locking element, wherein a wing of the window or the door by means of the espagnolette fitting in at least a closed and an open position can be brought wherein the locking elements are associated with a locking engagement and lie at least in an open position on both sides of this locking engagement. Due to the interaction of the locking element and the locking engagement of the wing is fixed to the frame. The possible by the invention different strokes of the driving and abortive drive rods, the locking elements cooperate to different switching positions with the locking engagement, so that it can be provided that initially a first locking element cooperates with the locking engagement and only subsequently a second locking element.

It can additionally be provided that on the espagnolette fitting at least one more open position of the wing is adjustable, in which a locking element cooperates with the locking engagement. As a result, a special lock in the Kippöffnungsstellung can be achieved.

It is also expedient if the coupling rod or slide assumes a position in the open position in which its or its articulation point on the abortive drive rod relative to the axis of the pinion is approximately diametrically to the articulation point on the pinion. In this particular embodiment, it may be provided that the driving drive rod and the driving drive rod each have a locking element. One of these locking elements engages in the locking and the tilting opening position in the same locking engagement and secures the tilted position.

It can be advantageously provided that the pitch circle of the pinion is designed so that at a maximum stroke of the driving drive rod, the pinion performs an approximately 360 ° pivoting movement. In a conventional espagnolette, which is manually driven by a hand lever, the hand lever is pivoted by 180 °. Accordingly, between two switching positions are 90 ° lever travel and the pinion completes a 180 ° pivoting movement, so that the abortive drive rod executes a maximum travel.

In the Fig. 1 a locking device 1 is shown, which consists of a frame side mounted, effective as a locking engagement strike plate 2 and a drive rod fitting component 3. The drive rod fitting component 3 has two drive rods 4, 5 and a pinion 6, which is in drive connection with the first driven drive rod 4 and with the second drive rod 5 in output connection. The pinion 6 connects the drive rods 4, 5 not directly but with the interposition of a coupling rod 7. The drive rod 4 is in the illustrated embodiment, the drive rod, which by a drive rod drive, not shown here, eg a transmission manually or by motor is driven. The drive rod 5 is articulated on the coupling rod 7 and is based on the pinion 6 abortive.

The coupling rod 7 is hinged to a flat surface of the pinion 6 pivotally connected to the in the Fig. 1 visible plan surface 8 hidden and parallel. The connection of the coupling rod 7 is such that the coupling rod 7 can perform a pivoting movement of 180 °.

For this purpose, the coupling rod 7 consists of two parallel pinions 6, which lead the coupling rod 7 by means of the pin 9 between them. The coupling rod 7 is connected to the drive rod 5 via a hinge 10, so that the drive rod 5 is guided exclusively parallel to the face-plate 11. Due to the described embodiment, in which two pinions 6 are parallel to each other, the stationary mounting of the pinion 6 can be simplified. This takes place along the plane surface 8 by means of a bearing block, not shown here, which is mounted on both sides of the pinion 6 and is connected to the face-plate 11.

Notwithstanding this, it can also be provided that only one pinion 6 is provided and either two coupling rods 7 or a coupling rod 7 engage with a U-shaped end on the pinion. However, it must be ensured via the translation of the pinion 6 and the drive rod 4, that the pivot angle is chosen so that the coupling rod 7 does not abut the required bracket.

In the illustrated embodiment, the locking device 1 is to be attached to a lower horizontal wing spar and serve to lock a tilt and a locking position. Starting from the in Fig. 1 shown locking position, the drive rod 4 is displaced in the direction of arrow 12 to in the in the Fig. 2 to get shown rotary position. The pinion 6 engages with its teeth 13 in a toothing 14 of the drive rod 4, so that when a displacement of the drive rod 4 by a partial stroke 15 or the pinion 6 perform a pivot angle of 180 °. Starting from the in the Fig. 1 shown extended position, in which the coupling rod 7 covers only in the region of the bearing on the pin 9 with the pinion 6, the pin 9 is in the in Fig. 2 illustrated opening position diametrically thereto. The coupling rod 7 covers the pinion 6 completely.

Due to the displacement of the drive rod 4, the locking element 16 is guided out of the latch opening 17. On the drive rod 5 is a locking element 18th attached, which is moved by the displacement of the drive rod 5 from the latch opening 19 out. The locking elements 16, 18 are moved on the partial stroke 15 in opposite directions.

Since the locking elements 16, 18 have been moved out of the striking plate 2 and all locking elements of the wing directly connected to the drive rod drive have been displaced to an opening position corresponding to the drive rod 4 and the locking element 16, the wing can now be opened.

If the drive rod drive is now operated again and the drive rod 4, starting from the in Fig. 2 shifted position shown by a partial stroke 20, the drive rod 4 is in an end position corresponding to Fig. 3 brought, in which the locking element 16 has a maximum distance to the strike plate 2. During the displacement of the drive rod 4, the pinion 6 is pivoted again by 180 °. As a result, the coupling rod 7 and the drive rod 5 reaches again in the Fig. 1 illustrated starting position and the locking element 18 engages in the latch opening 19 of the striking plate 2 a. The pitch of the pinion 6 is thus designed so that at a maximum stroke 21 of the drive rod 4, the pinion 6 performs an approximately 360 ° pivoting movement. Are - as described above - all other locking elements rigidly connected to the drive rod 4 and their assignment to the respective locking engagements according to the assignment of the locking element 16 to the strike plate 2, only the locking element 18 is in the closing engagement. This makes it possible to set a tilt lock, in which only one or possibly a plurality of locks constructed on the same principle are attached to the lower horizontal wing leg.

In the synopsis of Fig. 1 to 3 will be apparent that the axis 22 of the pinion 6 is slightly below the faceplate 11, so this is not visible on the visible surface 23 of the faceplate 11. The pinion 6 passes through a slot 24 in the faceplate 11 and projects in front of the visible surface 23. Here, a corresponding cover can be provided. The coupling rod 7 is at least partially in the slot 24. The drive rod 4 is spaced by means of a bend 25 from the face plate 11 that the engagement of the pinion 6 can engage the teeth 14 formed in the drive rod 4 by recesses.

In the embodiment of the FIGS. 1 to 3 is provided that the partial strokes 15, 20 have an equal size and that the total stroke 21 corresponds to the maximum stroke of the drive rod drive and thus the drive rod 4. The translation of the pinion 6 and the drive rod 4 is chosen so that the locking elements 16, 18 cover an approximately identical path. This is essentially achieved in that the pin 9 is approximately on the pitch circle diameter of the pinion 6.

By varying these parameters, starting from the various partial strokes 15, 20 of the drive rod drive, different times can be achieved at which the locking elements 16, 18 interact with the strike plate 2. In the illustrated embodiment, it is essential that the coupling rod 7 in the open position Fig. 1 assumes a position in which the articulation point formed by the joint 10 on the drive rod 4 with respect to the axis 22 of the pinion 6 approximately diametrically to, defined by the pin 9, articulation point on the pinion 6 is located.

The FIGS. 4 to 6 show a further embodiment of the locking device. Here, the drive rod 4 is assigned to the pinion 6 again. At the pinion 6 is the coupling rod 7 - as above with reference to the Fig. 1 to 3 already described - pivotally hinged to the pin 9. The coupling rod 7 forms at the end facing away from the pinion 6 a bearing 29 of a second pinion 30. The pinion 30 is associated with a stationary bearing 31, which is in the illustrated embodiment in the groove bottom of a locking device 1 receiving fitting groove of the wing but a component with the locking device 1 forms. The pinion 30 rolls in a toothing 32 of the bearing 31, resulting in each case a Momentalpol when rolling in the toothing 32 results. Accordingly, the respective diametrically located tooth is displaced by twice the path, so that the drive rod 5 is displaced by twice the way as the coupling rod 7. Such a translation is also referred to as a climbing gear and is from the DE-PS 1244611 already known, to which reference is made in this regard. Through the use of the climbing gear, the diameter of the pinion 6 can be kept small and the pinion 6 is only slightly above the face plate 11 before.

The operation of the locking device 1 is analogous to that in the FIGS. 1 to 3 explained locking device. When relocating the drive rod 4 in the direction of the arrow 12, on the one hand, the locking element 16 out of the strike plate 2 out and on the other hand via the teeth 14, the pinion 6 pivoted. The coupling rod 7 is moved by the pivoting movement of the pinion 6 against the direction of the arrow 12 - in the drawing to the left -, whereby the pinion 30 is dragged to the left. The engaging in the teeth 32 of the bearing 31 teeth 33 of the pinion 30 causes a pivoting movement of the pinion 30 in a clockwise direction. In this case, the pinion 30 from the in Fig. 4 shown location in the in Fig. 5 shown position carried. The drive rod 5 is moved so far by the engagement of the teeth 33 of the pinion 30 that the locking element 18 is led out of the latch opening 19. The locking device 1 thereby reaches, starting from the in Fig. 4 illustrated locking position, the open position accordingly Fig. 5 in which both locking elements 16, 18 are led out of the locking openings 17, 19.

Further displacement of the drive rod 4 in the direction of the arrow 12 (FIG. Fig. 4 ) causes the pinion 6 is pivoted by a further 180 °. The coupling rod 7 has starting from the position to Fig. 5 executed an oscillating movement and is located as shown Fig. 6 again in the position in which the coupling rod 7 is in the locked position to Fig. 5 has found. The Riegeelement 16 is maximally removed from the locking engagement 2 and the locking element 18 is moved into the latch opening 19.

In the embodiments of the Fig. 1 to 6 the locking elements 16, 18 are shown identical. However, it can be provided deviating from the fact that the locking elements 16, 18 have different dimensions, since the tilt lock and the locking position could require different freedom of movement for the locking elements 16, 18 in the bolt openings 17, 19. It is also possible to provide different shaped latch openings 17, 19 in addition to or together with identical latch elements 16, 18.

In the Fig. 7 to 9 is a further embodiment of the locking device 1 is shown. It is provided that the coupling rod 7 consists of a slide 35, in which a protruding from the flat surface 8 of the pinion pin 9 9 dips into a slot 36. The link 36 is perpendicular and extends partially above and partially below the faceplate 11. On the slider 35, the drive rod 5 is connected. The slider 35 is together with the drive rod 5 so mounted on the face plate 11, that this can be displaced exclusively in the longitudinal direction of the faceplate 11.

Now, the drive rod 4 in the position according to the lower illustration after Fig. 7 displaced, the pinion 6 is pivoted and the pin 9 moves in the link 36 down. Following the pin 9, the slider 35 and thus the drive rod 5 is displaced in the drawing to the left, so that the locking elements 16, 18 are led out in different directions from the strike plate 2 until in the Fig. 8 shown situation is reached. Analogous to the displacement of the drive rod 5 after Fig. 2 to Fig. 3 and the Fig. 5 to Fig. 6 is in a further movement of the drive rod 4 in the direction of the arrow 12, starting from the position Fig. 8 the drive rod 5 again moves in the opposite direction and the locking element 18 engages in the latch opening 19 ( Fig. 9 ).
Also in this embodiment can be provided that the coupling rod 7 engages around the pinion U-shaped.

The embodiment according to the Fig. 7 to 9 dispensed with the formation of a pivotable connection of the coupling rod 7 with the drive rod 5 in favor of the slide guide of the pin. 9

In the context of the invention, further embodiments are possible. Thus, for example, by changing the design of the dimensions of the pinion 6 or 30, it is possible to adjust the oscillating movement of the locking element 18 at different times. It can also be provided that one of the locking elements 16, 18 initially performs a partial stroke in a first direction and then a partial stroke in an opposite direction.

Finally, it should be noted that the illustrated embodiments as effective functional elements, the locking elements 16, 18 show. Deviating from this, however, further functional members of a locking device are conceivable, which interact with other functional members of the wing or frame. It would be conceivable Ausstellarme or the like. It is also conceivable within the scope of the invention for the two drive rods 4, 5 to extend parallel to each other along a wing spar, so that two drive rods 4, 5 are provided on each wing spar.

Notwithstanding the illustrated embodiments may of course also be provided that only on the drive rod 5, a single locking element 18 is provided and that the drive rod 4 carries no locking element. The oscillating movement of the locking element 18 can still be used to advantage
