Definitions

  • the present invention relates to a sunshade with a lamellae hanging from ladder cords, wherein turning tapes at the upper ends of the ladder cords or the ladder cords themselves are passed over spiral bearings which are coupled to at least one drive shaft to allow adjustment of the lamination inclination ,
  • the drive shafts at the same time still drive elevator bearings with which the extension length of the slat curtain can be adjusted. It is anxious not to let the travel times of the curtain be too long, so that the highest possible speed of the drive shaft is used.
  • the conductor cords are taken over suitable elements which comprise a friction clutch.
  • suitable elements which comprise a friction clutch.
  • the high rotational speed of the drive shaft requires that the adjustment of the inclination on the ladder cord is done relatively quickly, which hinders an exact adjustment of the slat angle, especially if the adjustment is done manually. But difficulties also arise in automatically controlled systems, since the position detection must be sensitive accordingly to be able to set an exact slat angle. Particularly problematic is the adjustment in trained as a so-called work position bearings turnbuckles with which a targeted intermediate position of the slat inclination is adjustable. In general, this working position is switched by a short reverse rotation of the drive shaft, said switching pulse at a correspondingly fast-rotating drive shaft control technology is very difficult to detect, so that there is a risk of switching errors.
  • the object of the present invention is to provide a sunshade system in which the inclination adjustment of the slats can be achieved more easily and with existing automatic control with higher reliability.
  • the object is achieved by a sunshade system of the type described above, in which the at least one continuous drive shaft is coupled nadostarr directly with drive elements with engine speed, which are connected to an end profile of the Lamellenbehangs via a flexible elevator member, and the drive shaft further via a transmission is coupled to the respective spiral bearing, which reduces the speed of the spiral bearing relative to the drive shaft.
  • the respective spiral bearing itself only rotates at a reduced speed relative to the drive shaft, so that on the one hand the drive shaft can rotate at the desired high speed to allow quick adjustment movements of the Lamellenbehangs, on the other hand, but also the spiral bearing itself with improved precision can be switched.
  • the number of coil bearings used depends on the number of conductor cords, since a spiral bearing is required for each ladder cord.
  • the lamellae hang on at least two ladder cords, but in the case of wider systems three or more ladder cords with corresponding turnbuckles can also be used.
  • the Reduction gear also not burdened with those drive torques required for extending and retracting the Lamellenbehangs.
  • the transmission can be kept small and integrated without major problems even with small top rails in the coil bearings.
  • the required for turning the slats drive torque is namely considerably smaller than the drive torque for adjusting the extension length of the curtain.
  • the transmission is designed as a planetary gear.
  • the advantage of planetary gears is that they require a small space, since the rotating parts are in coaxial arrangement with each other.
  • each planetary gear has a rotatably coupled to the winding shaft sun gear, a fixed ring gear and planet wheels, which are mounted on a rotatable planet carrier, which is coupled to the coil bearing.
  • the generally designed as polygonal drive shafts can be coupled by a corresponding inner cross section of the sun gear with this torsionally rigid, while the ring gear is supported stationary, for example, on a housing of the spiral bearing.
  • the planet carrier is preferably each rotatably mounted on a cylindrical extension of the associated sun gear, wherein the formation of a cylindrical bearing surface on a sun gear, for example made of plastic is easily possible, so that a separate storage is not required.
  • a variant of the drive elements provides that these coils are of elevator bearings, wherein the flexible elevator members are wound on the coils of the elevator bearings whose other ends are fixed to an end profile of the Lamellenbehangs. Such embodiments are frequently encountered.
  • an elevator bearing for catching the curtain is integrated into the housing of the spiral bearings, which is directly coupled torsionally rigidly with the winding shaft, wherein on the elevator bearing a flexible elevator organ, such as a cord or a belt, can be wound up whose other end is fixed to an end profile of the Lamellenbehangs.
  • the coil bearing according to the invention is preferably designed as a so-called work position bearing, which has a coupling by means of which the helical bearing can be disengaged from the drive shaft.
  • the coupling fixes the coil bearing in a specific or arbitrary intermediate position when the working position is activated.
  • the entrainment takes place between the planet carrier and coil bearings via a friction clutch, wherein the friction clutch then slips when the coil bearings are blocked in a desired position, the slipping due to the only low forces, which are necessary for operating the reversing bearing with correspondingly adapted coefficients of friction, no high power loss means.
  • a switching mechanism is preferably provided which blocks by means of a movable switching element, the coil bearing in any angular position.
  • the triggering of the switching mechanism is preferably carried out by a reverse rotation of the drive shaft by a certain angle.
  • FIG. 4 and 5 show a combined lift / turn bearing 10, which is used to control sun protection systems with lamellae hangings please refer Fig. 4 and 5 is used.
  • Such bearings are seated on a driven, for example, by an electric drive motor drive shaft, which has a square cross section for the example shown, will be discussed in more detail.
  • the combined bearing 10 has an elevator bearing 12 which is made of plastic and forms a winding roll for a textile belt (not shown).
  • the windable textile tape is guided by the lamellae and connected to the end profile, so that upon movement of the elevator bearing 12, the extension length of the curtain is adjusted, wherein when entering the lamellae stack on the end profile.
  • the reel 14 of the elevator bearing 12 has a drive shaft corresponding to the square-shaped inner cross-section 15, so that a positive entrainment of the coil 14 is given by the drive shaft at the same speed.
  • the storage of the coil 14 by means of a cylindrical bearing surface 16 which is rotatably mounted in a corresponding cylindrical inner cross section 18 of a bearing wall 20.
  • the bearing wall 20 also limits the width of the coil in the mounted state, i. only one side wall of the coil is in fact rotatable.
  • the bearing wall 20 is fixedly supported in a housing 22, wherein the housing 22 is closed by a cover 24 after mounting the bearing parts.
  • the spiral bearing 26 consists essentially of a Wendebandage 28, which has a circumferential groove 30 with thickened recesses 32 in its periphery, in the balls 34 are inserted, which are connected to a turning belt 36, with the ladder cord not shown is connected.
  • This ladder cord carries the individual slats, for example via transverse webs or other suitable support members.
  • the turning band is positively coupled to the turning tape receptacle 28.
  • the friction surface 38 cooperates with spring tongues 42, which are provided on the inner circumference of the Wendebandage 28.
  • the VerFEweg the Wendebandage 28 is limited by stops, of which only one stop 43 can be seen in the figure. These stops limit the range of rotation and thus the angle adjustment of the slats of Lamellenbehangs. Once the attacks have run against a corresponding stop in the housing 22, the Wendebandage is blocked, whereupon the friction clutch slips, while the further rotating drive shaft up or down the hanging by the further rotating elevator bearing 12.
  • the helical bearing 26 is preceded by a pre-gear, which reduces the speed with respect to the drive shaft.
  • the primary gear is designed as a planetary gear 44, which consists of a rotationally fixed on the drive shaft sun gear 46, a stationary mounted in the housing ring gear 48 and three planetary gears 50 which are rotatably mounted on bearing pins 52 which are formed on the planet carrier 40.
  • the sun gear 46 is formed as a hollow cylinder whose inner cross section square shaped according to the drive shaft is trained.
  • a first bearing surface 54 serves to mount the drive shaft on a corresponding bearing surface 56 on the housing 22, wherein at the opposite end of the housing, a second bearing surface 58 is provided which cooperates with a further cylindrical bearing surface 60 on the bobbin 14 of the elevator bearing.
  • the sun gear 46 also has a further cylindrical bearing surface 62, on which the planet carrier 40 is rotatably mounted.
  • the advantage of the planetary gear 44 is that the rotational speed of the spiral bearing with respect to the rotational speed of the drive shaft depending on the configuration of the teeth in the usual housing diameter by a factor of three to four can be reduced.
  • a quick adjustment of the extension length of the Lamellenbehangs possible while on the other hand, a precise adjustment of the slat angle is possible.
  • desired tilt settings can be set precisely, even with an electronically controlled tilt adjustment.
  • Fig. 3 shows an embodiment of another combined elevator / turnaround bearing 110, which is structurally similar in many parts, so that the same reference numerals are provided accordingly. Deviations exist in the area of the formation of the friction clutch and the limitation of the stops of the spiral bearing 126. Instead of the radially acting on a sliding surface spring tongues, a friction surface 138 is integrally formed on a planet carrier 140 in this embodiment, which is looped by a wrap spring 142. A turning belt spool 128 is integrally connected to a driving plate 129, wherein the composite of Wendebandspule and drive plate on a sliding surface 20 is mounted.
  • the drive plate 129 has a first radial slot 143 and a second radial slot 145 through which radially outwardly bent leg ends 147/149 of the wrap spring 142 protrude.
  • the spring ends 147/149 take in the respective direction of rotation on the flanks of the slots 143, 145, the drive plate 129 and thus the turning belt coil 128, so that the inclination angle of the slats can be adjusted.
  • the angle of rotation of the helical bearing 126 is limited by housing-side stops (not shown) in the housing 122. These cooperate with the leg ends 147 and 149 of the wrap spring 142. As soon as the respective spring end abuts against the abutment, the entraining force of the spring on the friction surface 138 is relieved so that the frictional torque is simultaneously reduced when the stop is reached. This has an advantageous effect on the necessary driving forces to up and down the curtain by means of the elevator bearing 12 under blocked coil bearings 126.
  • the spiral bearing can be formed by additional elements as a so-called work position bearing, in which between the attacks an intermediate position of the slats can be fixed so that when a shutdown of the curtain this does not remain in a closed slat position and set separately after the extension to the desired length must be, but already during the shutdown assumes the desired slat position.
  • Fig. 4 and Fig. 5 show views of complete sunshades, the mode of action of the previously described camp as well as an alternative embodiment thereof.
  • Fig. 4 shows a Venetian blind 70 with a Lamellenbehang 72, which consists of a plurality of fins 74 and a lower end of the curtain 72 forming end profile 76.
  • an electric drive motor 80 is provided with two-sided output, which is coupled via two drive shafts 82 with the two winding / turn bearings 110, the in Fig. 3 and the associated description parts have been explained in detail.
  • Conductor cords 84 which are guided over the turning coils 128 and connected to the edges of the fins 74, so that the desired turn can be performed by operating the coil bearings.
  • elevator belts 86 which are guided through openings in the slats 74 and connected to the end profile 76 in order to be able to move in and out the curtain.
  • the elevator belts 86 can be wound onto the respective reel 14.
  • lateral guide pins 88 shown may engage (not shown) in lateral guide rails to stabilize the curtain.
  • FIG. 5 another example of an external venetian blind 170 is shown, in which compared to Fig. 4 similar or corresponding components have received the same reference numerals.
  • the motor 80 arranged in the upper rail 78 drives two spiral bearings 210 via two drive shafts 82, which are similar to those in FIG Fig. 3 shown elevator / Wendelager 110 are formed, however, have no winding bobbin, since they serve only the turn of the curtain over the conductor cords 84.
  • the drive shafts 82 protrude laterally from the upper rail 78 and are there provided with a directly fstarr connected to them toothed disk 212, via which a toothed belt or a chain 214 is guided, which extends in a laterally arranged guide rail 216.
  • a corresponding deflection (not shown) of the chain 214 may be provided, which entrains the end profile 76 during adjustment. But it is also possible to lead a loose end of the chain in the guide rail, which is connected to the end profile and this entrains, while the other end runs free of load in a hollow chamber of the guide rail.
  • Fig. 5 illustrates that the inventive coil bearings can be combined with completely different structural embodiments of elevator devices for the system.
