Definitions

  • the invention relates to an actuating device according to the preamble of claim 1.
  • An actuator of this type is known from DE-A-26 37 067.
  • the train here is a cord that is led outwards and on which the curtain strips can be moved both horizontally and pivoted about their vertical axes.
  • This actuating device requires a special towing vehicle for horizontally moving the curtain strips, this towing vehicle itself not carrying a curtain strip.
  • this towing vehicle moves unintentionally when the curtain strips are pivoted, which makes it almost impossible or very difficult to align the curtain strips evenly.
  • PE-A-0 381 203 discloses an actuating device with a pull cord and a turning shaft, the turning shaft here not being rotatable with the pull cord, but having to be actuated separately.
  • Two spherical parts are attached to the pull cord, which work together with locking receptacles of two pulling carriages and thereby form a detachable locking seat.
  • An actuating device with two separately actuated drive elements is also shown in US Pat. No. 4,653,564.
  • the invention has for its object to provide a device of the type mentioned, with which the curtain strips can be actuated more precisely and which is also simpler in construction and thus less expensive to manufacture. The object is achieved according to claim 1.
  • the precursor is not moved by means of the shaft, but rather directly with the carriers of the train, which can be a cord train.
  • the shaft does not have to be rotated, which means a significant reduction in the operating noise and the torsion of the shaft.
  • the low torsion also allows very long actuators, for example with a length of 4 m.
  • the transmission for transmitting the movement of the train to the shaft can be stationary, for example attached to the curtain rail, which allows a much simpler assembly and less expensive manufacture.
  • the precursor can then largely be designed like the other sliders. A special train carriage is therefore not necessary. It is also essential that in the actuating device according to the invention the force for rotating the curtain strips is better separated from the force for displacing the curtain strips.
  • the curtain strips can be moved much faster than with the previously known actuating device and the curtain can thus be closed more quickly.
  • the actuating device according to the invention can be implemented with fewer individual parts and with a simpler construction.
  • the actuating device has a curtain rail 1 with the cross section shown in FIG. 4. At one end of the rail 1, an end housing 4 is placed, in which a bevel gear 10 is mounted. This housing 4 is closed with a cover, not shown here. At the other end of the rail 1 there is a further end housing, not shown here, in which deflection rollers 7 for a cord 8 are accommodated.
  • the curtain rail 1 is attached to a building ceiling in front of a window.
  • a plurality of sliding elements 24 are arranged in the curtain rail 1, a foremost sliding element 24a forming a forerunner.
  • Each sliding element 24 and also the forerunner 24a each have a pivotable axis 29 to which a curtain strip 34 is attached.
  • the attachment is carried out here with a cam 30 formed on the lower end of the axis 29.
  • the sliding elements 24 are guided with rollers 25 on side lugs 3 of the curtain rail 1 so that they can slide.
  • the axes 29 of the sliding elements 24 project outwards through a longitudinal slot 2 which extends over the entire length of the rail 1. When the sliding elements 24 are moved, the curtain strips 34 are accordingly also moved in the longitudinal direction of the rail 1.
  • Each sliding element 24, including the precursor 24a, has a continuous round opening 40 through which a control shaft 23 extends, which is connected in a rotationally fixed manner in each sliding element 24 to a worm 27 of a worm gear 26.
  • the axis 29 is pivotably supported to a limited extent and has a worm wheel 28 which meshes with the worm 27.
  • the control shaft 23 is rotated, the axis 29 and thus the curtain strip 34 attached to it at the bottom are pivoted in one direction or the other.
  • worm gears are known, for example, from EP-W 0 181 465 of the application.
  • the control shaft 23 is pivoted by means of the cord 8, which is connected to the gear 10 mounted in the end housing 4.
  • This bevel gear 10 has a gear 13 which is pushed onto the shaft 23 with a through opening 13b and is connected to the shaft 23 in a rotationally secure manner.
  • the gear 13 is rotatably supported by a cylindrical projection 13a which engages in a circular opening 6 of the end housing 4.
  • a gear part 14 shown in more detail in FIGS. 6a and 6b has two spaced-apart slide bearings 12a and 12b, which are inserted into corresponding bearing points 5 of the end housing 4 and are fixed by means of latching.
  • the bearings 12a and 12b are formed on a shaft 16 which carries a gear wheel 15 at one end and which is connected via a slip clutch 18 to two drive wheels 19 and 20 arranged at a distance from one another.
  • the wheels 19 and 20 are firmly connected to a part 21 of the slip clutch 18 and are arranged at a distance from one another such that there is a groove 22 between them, in which the cable 8 engages in its deflection area and by friction when the cable 8 is pulled the wheel 15 rotates in one direction or the other.
  • the cord 8 can thus the shaft 23 about its longitudinal axis in one or the other Direction.
  • the axes 29 can be pivoted to a limited extent in both pivoting directions. If the axes 29 are pivoted up to a stop, the control shaft 23 can no longer be rotated in the same direction.
  • the slipping clutch 14 now allows the cord 8 and 2 to be firmly connected to the driver 9 in the same direction as before.
  • the curtain strips 34 are now moved in the longitudinal direction of the curtain rail 1, as will be explained below with reference to FIGS. 1 to 3.
  • Recesses 19a and 20a on the circumference of the wheels 19 and 20 and corresponding recesses on the deflection rollers 7 ensure that the drivers 9 do not line up at the deflection points.
  • the cord pull 8 on the strand 8b is moved downward in the direction of the arrow 38, as shown in FIG.
  • the driver 9 located in the transmission 10 in FIG. 1 now runs unhindered around the transmission part 14 and through the comparatively large openings 32 until, according to FIG.
  • the precursor 24a is now carried to the left by the cord 8, and the remaining sliding elements 24 are also moved in turn to the left by the distance limiting member 31.
  • the curtain strips 34 are shifted to the left in the direction of the arrow 36, these again not being pivoted as a result of stops in the gears 26.
  • the shaft 23 stands still during the entire longitudinal displacement of the curtain strips 34 and the slip clutch 21 rotates.
  • the distances between the sliding elements 24 are all the same, which is determined by the distance limiting member 31.
  • the curtain strips 34 can thus be opened or opened in both directions of the curtain rail Closing the curtain are moved, the respective shaft 23 is not rotated and the curtain strips 34 are not pivoted.
  • FIG. 3 The pivoting of the curtain strips 34 is shown in FIG. 3.
  • these can be pivoted in the direction of the arrow 37, but not in the opposite direction, since this is prevented by appropriate stops in the gears 26.
  • the strand 8a is moved downwards in the direction of the arrow 39.
  • the driver 9 still resting on the precursor 24 according to FIG. 3 now moves to the right away from the precursor 24a.
  • the drivers 9 now have no effect on the sliding elements 24 and accordingly they are not moved in a longitudinal direction of the curtain rail 1.
  • the cord 8 now rotates due to its friction on the gear part 14 in the direction of arrow 42 about its axis of rotation.
  • the slip clutch 21 takes the gearwheel 15 with it and accordingly the shaft 23 is rotated in the direction of arrow 43.
  • the gears 26 transmit the movement of the shaft 23 to the curtain strips 34, which are pivoted in the direction of the arrow 37 as desired.
  • the curtain strips 34 run transversely to the curtain rail 1
  • Curtain strips 34 are pivoted by approximately 160 ° with respect to the arrangement according to FIG. 3 and, moreover, cannot be pivoted further as a result of stops in the gears 26. If, starting from this end position, the strand 8b is moved downward in the direction of the arrow 38, the curtain strips 34 pivot in the opposite direction of the arrow 37 up to the end position shown in FIG. 3.
  • any desired intermediate position of the curtain strips 34 is easily possible. It is now essential that during the mentioned pivoting movements of the curtain strips 34, the drivers 9 do not line up with the precursor 24a and move it. The distance between the drivers 9 must therefore not be less than a certain value. The distance is particularly dependent on the gear ratio of the gears 26.
  • the drivers 9 are preferably fixedly attached to the cord 8, as a result of which the said distance is then fixed.
  • the curtain strips 34 are thus also pivoted by actuating the cord pull 8.
  • the actuation is carried out by hand, but motor actuation in itself is not excluded.
  • the cord pull 8 can also be another suitable actuating element, for example an endless chain.
