The sliders are actuated by adjusting knobs (11, 12). The snap-fit rockers are controlled by a resetting unit. An actuating unit is formed by an individual adjusting button or by the adjusting knobs. End position adjustment process is executed by one time actuation of the adjusting button and/or the adjusting knobs.

Description

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

Such Endlageneinstellvorrichtung is through the DE 100 40 560 known. It has a Endlagenabschaltvorrichtung with a differential gear. For the respective end position, two switching discs seated on one another are arranged rotatable relative to one another, which are driven at different speeds by gears equipped with different numbers of teeth and which are connected to the switching disc axes via slip clutches. The switching disc axes are juxtaposed, and the switching discs have on their circumference in each case a notch, in which a biased to the switching disk circumference Schaltarmspitze a switching arm can intervene, the case via a Deflection lever actuated a switch plunger of a microswitch. The Endlageneinstellvorrichtung further comprises actuating means in the form of a respective adjusting slide for each end position, which is connected to retaining means for holding the switching disc axes and with blocking means for preventing the incidence of the switching tip in the notches during the setting operation in operative connection. The intended for the relevant end position adjusting slide is operatively connected to a locking device acting in the setting state, and the retaining means are formed and controllable by a standing with the switching disc axes return means that they trigger the locking device and reset the locked adjusting slide.

The disadvantage of the above-mentioned invention is that two adjusting slides, each with one actuating button, are required here for the end position settings, wherein these actuating buttons are to be pressed alternately for the upper end position and lower end position of the roller shutter curtain.

The object of the invention is to provide a Endlageneinstellvorrichtung mentioned in the preamble of claim 1, in which the adjustment regardless of the direction of travel of the drive for Endlageneinstellung with only one adjustment knob as the actuating means for adjusting the upper end position or lower end position respectively is pressed only once.

This object is achieved with the features of claim 1. Further, expedient and advantageous embodiments of the invention will become apparent from the dependent claims.

The user initiates the setting process with the drive stationary or running by pressing the set button. Then he drives the drive to the desired first (eg upper) end position, whereby the adjusting slide for the opposite direction thereby disengages, while the adjusting slide for the desired direction of travel automatically remains in depressed position. When the first end position is reached, the drive must be operated in the opposite direction of travel, whereby the adjusting slide for the opposite direction of travel automatically resets and ends the adjustment process and whereby the position of the first end position is stored. To set the second end position, repeat the process in the opposite direction. A significant advantage of the present invention is the direction-independent adjustment of the end positions, because the adjusting slide for the opposite direction is always unlocked automatically.

A further advantageous embodiment of the invention is such that the switching disks lie inside each other and each have the recess at their axial ends and that the Schaltarmspitze is biased frontally to the switching discs.

A further embodiment of the invention is such that the provision of the adjusting slide is forced by means of a laterally mounted return spring by a radially and axially mounted on the control discs guide with limitation to the provision of the adjustment slide.

A further, alternative embodiment of the invention is such that the switching disks lie one above the other and each have the recess on its circumference and that the switching arm tip is biased radially to the switching disks. This allows the Endlageneinstellvorrichtung be accommodated in a confined space. In this embodiment of the invention, a two-slider operation can be implemented.

In Fig. 1 a Endlageneinstellvorrichtung 1 according to the invention is generally illustrated, this Endlageneinstellvorrichtung 1 is provided together with a Endlagenabschaltvorrichtung for the end position adjustment and end position shutdown of a blind, an awning, a blind or other shading system and is housed in a box-shaped outer housing 2. The screwed onto the outer housing 2 cover has been omitted. Similarly, a part of the Endlageneinstellvorrichtung 1 receiving differential gear housing has been omitted, are stored in the axes of these parts.

The outer housing 2 receives on its bottom 3, a circuit board 4 with a printed circuit. On this board 4 is not shown, open at the top and bottom differential gear housing. In the left part of the outer housing 2, a sleeve 6 is formed, whose inner end is provided with four pins 6 '. These pins 6 'are connected via the printed circuit 5 with two microswitches. In the sleeve 6, a connector can be inserted. At the bottom of the outer housing 2, two further sleeves 9, 10 are formed, in which adjusting means, here knobs 11, 12 are guided.

The Endlageneinstellvorrichtung 1 consists now essentially of two differential gears 13, 14, of which only one lower gear is shown with its Rastnasenträger 17, 18, a differential gear 13, 14 driving pinion 19, two with the detent nasal 17, 18 in engagement here engageable detent rockers 20, 21, which are biased by one or more compression springs 22, two adjusting slides 23, 24, on the one hand with the locking rockers 20, 21 are engaged and on the other hand with the adjusting means, here knobs 11, 12 are pivotally connected, two slide detents 25, 26 and the adjusting means, here knobs 11, 12th

The outer housing 2 carries on its rear side a guide neck (not shown), the circumference of which is perforated for the implementation of the pinion 19. On this guide piece, a pipe section is guided, which is provided with an internal toothing, which can be brought into engagement with the pinion 19, and which is rotatably connected to the winding tube of the roller shutter, the awning, the blind or other shading system.

In Fig. 1 is also the structure of the slide detents 25, 26 indicated, which will be explained with reference to the right slide detent device 26. From the bottom 2 of the outer housing 2 protrudes a bulbous molding 27, over the sides of the ends of the one end of a safety pin resembling spring 28 slide, but these ends develop a pressure inside. Thus, the adjusting slide 24 can be engaged once before and the other time behind the molding 27. The adjusting slide 24 is in Fig. 1 engaged in front of the molding 27 (non-actuated or triggered knob 12) while the adjusting slide 23 is engaged behind a corresponding molding (actuated adjustment, here knob 11). Basically, it should be emphasized that the user does not need to think about which knob he has to press to set a specific end position. Although markings on the knobs could help, but since the installation position of the Endlageneinstellvorrichtung may be required at different ends of the winding tube, the handling of such a device for the each adjustment (top and bottom) both adjustment, here adjusting buttons 11, 12 to press simultaneously.

A closer view of an alternative Endlageneinstellvorrichtung 1 'is in the Figures 2 and 3 to see Fig. 2 with microswitches 7, 8 and Fig. 3 without these microswitches. The alternative is to be seen in that for the adjusting means, here knobs 11, 12 a common adjusting body, here a common setting button 29 is provided. The user presses only this set button for each adjustment, the adjustment means, here knobs 11, 12 are operated simultaneously. Incidentally, the adjusting devices 1, 1 'correspond to each other.

In Fig. 2 the microswitches 7, 8 are provided at the bottom with connecting pins such as the connecting pin 30 and at the top with switch tappets 31, 32. These pins are connected to the printed circuit (5). The switching plunger 31, 32 are actuated by tabs 33, 34 of switching arms 35, 36. When not actuated switch plunger 31, 32, the micro-switches 7, 8 are turned off (circuit for the winding shaft driving tubular electric motor is interrupted). The two switching arms 35, 36 are movably mounted on a common axis 37, which is mounted in said differential gear housing, not shown. The switching arms 35, 36 are provided at their the tabs 33, 34 opposite ends with Schaltarmspitzen 38, 39. The function of these Schaltarmspitzen in connection with the differential gears 13, 14 will be explained in more detail. Recognizable is off Fig. 2 Also, that the differential gear 13, 14 axes 40, 41 which are mounted in the differential gear housing. Further, the adjusting slide 23, 24 are provided on the outside with guides such as the guide 42 through which the adjusting slide 23, 24 are guided on corresponding ribs of the differential gear housing. Above these guides is in each case a return spring 43, 44 can be seen, which is attached to the associated adjusting slide 23, 24, serves to return this adjustment slide and in each case cooperates with an associated stop 45, 46, as will be explained in more detail.

The Fig. 3 allows the absence of microswitch more details of Endlageneinstellvorrichtung 1 'recognize. The switching arms 35, 36 are, as can be seen on the switching arm 36, provided with vertical Schaltarmteilen such as the Schaltarmteil 47, which is in operative connection with a projection of the adjusting slide 24 (the same applies to the switching arm 35). In the not shown, latched state of the adjusting slide 24 this holds the switching arm 36 in a state in which the associated micro-switch is turned on. Only when the adjusting slide 24 has been reset by the return spring 44, the switching arm 35 releases the way for turning off this microswitch. Incidentally, it should be noted that the parts 13,14, 20-24, 35, 36 and the differential gear housing, not shown, forms a module which is used as such in the outer housing 2, wherein the detent rockers 20, 21 by pinning by means of corresponding axes in the differential gear housing, the differential gear 13, 14 by simply dropping into the differential gear housing and pinning by means of the axes 40, 41 and the switching arms 35, 36 can be fastened by subsequent pinning by means of the common axis 37.

In the following FIGS. 4 to 13 Now individual arrangements or items of Endlageneinstellvorrichtung 1 and 1 'are shown in more detail.

In Fig. 4 is a left part of the Endlageneinstellvorrichtung 1 and 1 'shown enlarged again. From it can be seen that the differential gear 13 (the same applies to the right part) nested switching discs, namely an inner switching disc 48 and an outer switching disc 49 has. In the end faces of these disks 48, 49 recesses are arranged, in which the Schaltarmspitze 38 can occur when these recesses are adjacent. These recesses are next to each other when the associated end position of the shutter, the awning, the blind or other shading system is reached. When the Schaltarmspitze 38 of the associated microswitch (7) is turned off and thus turned off the driving tubular electric motor.

Out Fig. 4 It can also be seen that the circumference of the indexing disc 49 is provided with an abovementioned stop 45, into which a transversely extending over the circumference, inclined plane 52 (shift gate) opens. The stop 45 opposite a further stopper 45 'with an associated, inclined plane 52' is arranged. At the periphery of the inclined plane 52, the return spring 43 abuts against the switching disk 49. If the indexing disk 49 rotates clockwise from above, nothing happens; a latched adjusting slide 23 remains in its locked position. However, when the indexing disk 49 rotates to the left, the free end of the return spring 43 runs up the inclined plane 52 until the stop 45 is reached. After reaching the stop 45 (or the stop 45 '), the adjusting slide 23 is reset and thus the associated adjustment, here setting button (11) triggered again. By providing two stops 45, 45 ', the provision can be made after half a turn of the switching disk 49.

The arrangement of Fig. 4 is in Fig. 5 shown again from another perspective, from which the engagement of the locking rocker 20 in the differential gear 13 and the adjusting slide 23 is better recognizable. The locking rocker 20 (see also Fig. 12 ) has on its one side a Druckfederaufnahetopf 53, on its other side two locking lugs 54, 54 ', of which in Fig. 5 only the locking lug 54 can be seen, and at the end of a projection 55. The locking lug 54 is behind a latching lug 56 of the aforementioned latching carrier 17 latched, while the projection 55 is latched behind a arranged at the end of the adjusting slide 23 locking lug 57. The latching of the locking lug 54 'and the structure of the differential gear 13 will be explained in more detail.

Fig. 6 again shows the differential gear 13 increases. You can see the two nested disks 48, 49 with their recesses 50, 51, the stops 45, 45 'with their inclined planes 52, 52' and two gears, an upper Gear 58 and the lower gear 15. The gears have in a known manner slightly different numbers of teeth, for example, 40 and 41st

In the Figures 7-9 Now the differential gear 13 is shown in an exploded side view and in end views closer. Fig. 7a shows the internal switching disc 48 with the recess 50 and with axle sections 60, 61. The shape of the axle section 61 goes out Fig. 9 out. Fig. 7b shows the outer switching disc 49 with stop 45b, slated plane 52 and a central recess 62 into which the indexing disk 48 fits. On the indexing disk 49 close successively a latching nose 17 'with a latching nose 56', an axle 63 and an axle 64 at. The arrangement after Fig. 7b has a central bore into which the axle 60 fits. In Fig. 7c the gear 58 is shown having a central opening into which the shaft portion 63 fits. In Fig. 7d the already mentioned latching nosepiece 17 is shown with the latching lug 56, with an axle section 65, with a central recess 66 and a central opening 67. The axle section 64 fits into the recess 66, and the axle section 61 fits into the central opening 67. An end view of the latching nose support 17 and its axle section 65 is shown in FIG Fig. 9 shown. The detent-holder 17 'and the axle section 63 look the same except for the other central opening. In Fig. 7e the lower gear 15 is shown. In Fig. 8 is an end view of the gear 58 and 15 can be seen. These plastic gears have on their inner circumference eight spring segments such as the spring segment 68, to which an annular groove 69 connects to the outside, in which an open spring ring 70 is mounted. The spring ring 70 presses these spring segments inward, so that so that a slip clutch can be built up.

The parts of Figures 7a-7e are now joined together in the following way. The gear 58 is pressed onto the shaft portion 63, and from the FIGS. 7b, 7c formed unit is attached to the axle 60. The gear 15 is pressed onto the axle portion 65, and from the FIGS. 7d, 7e formed unit is attached to the axle 61. With the gear 58 so the outer switching disc 49 rotates by means of a slip clutch, and with the Gear 15 rotates by means of a slip clutch, the internal switching disc 48. If the indexing discs 48, 49 are held by means of the detents 56, 56 ', the gears 15, 58 can still rotate on these slipping clutches. The detention of the detents 56, 56 'can be done with the locking lugs 54, 54' of the locking rocker 20.

In Fig. 10 is again the switching arm 35 shown with its Schaltarmteil 47 ', its tab 33 and its Schaltarmspitze 38 enlarged, and in Fig. 11 is again shown the switching arm 35 with his Schaltarmteil 47 ', his tab 33 and his Schaltarmspitze 38 from another perspective enlarged.

The Fig. 12 shows the locking rocker 20 increases. There are the Druckfederaufnahetopf 53, the projection 55 and the two locking lugs 56, 56 'can be seen, between which an opening 71 is arranged, in which the upper gear 58 can occur.

In Fig. 13 is again the left adjusting slide 23 shown enlarged with its return spring 43. The return spring 43 is clipped in a simple manner behind behind the return spring arranged brackets 72-75. Furthermore, the guide 42 and relative to the locking lug 57 can be seen at the differential gear end. At the other end of the adjusting slide 23 are a bore 76 and a recess 77 for connection to the associated adjusting means, here adjusting knob 11 and holes 78 for the passage of the spring 28 can be seen.

The hitherto described adjustment device 1, 1 'is assembled in a confined space and can therefore be used even in the smallest shading systems. Nevertheless, for reasons of space, a pipe structure may be required, as he for example in the Fig. 14 is indicated. The differential gear 13, 14 of Endlageneinstellvorrichtung 1 "do not lie next to, but in succession, but are operated in an analogous manner.

The operation of the Endlageneinstellvorrichtung 1, 1 'with the Endlagenabschaltvorrichtung is the following. The setting process of the end positions is independent of which adjusting means, here adjusting knob 11, 12 is actuated. Both adjusting means, here adjusting knobs 11, 12 at the same time or the adjusting body, here the adjusting key 29, are actuated. The setting process is only dependent on whether the user controls the shading system by means of the electric motor up or down. In any case, both adjusting slides 23, 24 are brought into the actuated locking positions in which the projections of the locking rockers 20, 21 as the projection 55 of the locking rocker 20 can place behind the associated locking lugs 57 of the adjusting slide. If the direction of rotation of the tubular electric motor is now directed so that, for example, the left differential gear 13 rotates clockwise and thus the right differential gear 14 rotates clockwise, the left latch rocker 20 engages the latching gear carriers 17, 17 ', so that the shift disks 48 , 49 are held and the gears 15, 58 on the slip clutches can continue to turn into the final position. The Endlagenzustand the gears 15, 58 is held by the sunken shift arm 35. In contrast, the differential gear 14 rotating to the left can not engage the associated latching rocker 21. The direction of rotation is directed so that after half a turn the adjusting slide 24 is reset by means of the associated return spring 44 again. In the normal operation of the shading system formed with the switching arm 35 Endlagenabschaltvorrichtung comes into play. When the end position is reached, the switching tip 38 falls into the recesses 50, 51 and the electric motor is switched off. The processes for setting the other end position and the operation when reaching this end position take place in an analogous manner.
