Definitions

  • the invention relates to a device for shading a building opening etc., in particular a venetian blind, with a curtain consisting of slats arranged in parallel one above the other and a lower end rail, the slats being able to be pulled up and lowered to form a stack of slats by a number of lifting straps engaging the end rail and / and are pivotable about an axis parallel to the longitudinal side by a number of turning belts engaging the longitudinal sides of the slats, and with a drive unit containing a winding shaft that can be driven by an electric motor for actuating the lifting belts and / or the turning belts, the electric motor of the drive unit being an off switch is assigned, which can be actuated by means of a transmission element, which is designed as a two-armed rocker, on one of which, the curtain-overlapping arm, the curtain runs up when it reaches its end position, which is pulled up to form a stack of slats.
  • a transmission element which is designed
  • a device of this type is known from JPS 6044994 U.
  • the winding shaft and the electric motor of the drive device through which it passes are arranged vertically above the curtain.
  • a pressure switch with a lateral stroke is provided. This does not protrude from one side of the electric motor, but is designed as a separate component that is arranged above the curtain so that its laterally movable push button can be actuated by means of the two-armed rocker.
  • the arm of the two-armed rocker assigned to the push button of the off switch is designed as a cam located next to the off switch, which cooperates with the push button when the rocker is actuated and moves it laterally. Arrangements of this type require a lot of space in terms of height, so that there is a risk that the stack of lamellas in its raised end position will cover the upper area of a window to be shaded, which is undesirable.
  • the drive unit is arranged transversely to the curtain level next to the slat stack, the electric motor of the drive device being placed so that its off switch protruding from one side points upwards, and that the two-armed rocker forming the transmission element with her second arm overlaps the upward-facing off switch of the electric motor.
  • the drive unit including the winding shaft and electric motor, is arranged next to the curtain, this advantageously results in a very low construction, so that the stack of lamellas in its raised end position usually completely exposes an associated window and advantageously does not appear disruptive.
  • the two-armed seesaw does not Linear guide, but only a simple pivot bearing is required, so that a very simple, low-interference design with high functional reliability results.
  • the two-armed rocker can advantageously be placed above the drive device and the stack of lamellas, so that no space is required in the area between the stack of lamellas and the drive device arranged next to it, which favors a space-saving design. With the measures according to the invention, the object mentioned at the beginning is therefore achieved in a very simple and inexpensive manner.
  • a housing can be provided to accommodate the curtain and the drive device arranged next to it, which has upper support devices and a lower passage slot for the curtain and in which a downwardly open profile rail accommodating the drive device is arranged, the upper wall of which is preferably from as Mushroom button trained off switch is penetrated.
  • the head strip containing the drive unit like the curtain, can be inserted into the housing as a completely preassembled structural unit, so that overall a completely preassembled arrangement results.
  • a bearing block can be arranged on the upper side of the head strip, on which the rocker is pivotably mounted.
  • the preassembled structural unit can therefore advantageously also contain the rocker functioning as a transmission element.
  • the rocker and the bearing block can expediently be provided with bearing elements that can be snapped into one another with a degree of freedom of rotation, which enables simple assembly.
  • a further advantageous measure can consist in that an exchangeable compensating plate can be detachably fixed on the underside of the arm of the rocker assigned to the off switch.
  • the compensation plate can expediently be releasably fixable on the rocker by means of a latching connection having two spring legs. This enables a simple, quick exchange.
  • the superordinate measures can be provided in an electric motor that is provided with buttons adjacent to the off switch for setting the end positions of the curtain that the Switching heads are accessible from above via an associated recess in the upper wall of the head strip and can be actuated by means of a U-shaped adjustment bracket that overlaps the head strip from above.
  • the ends of the lateral legs of the adjustment bracket are advantageously accessible from below, so that the adjustment of the end positions of the curtain can be carried out from below.
  • the side legs of the adjustment bracket can expediently be provided with lower grip tabs.
  • Another useful measure can be that the upper web of the adjustment bracket has projections assigned to the push buttons, which increases reliability.
  • Another particularly favorable measure can be that the side legs of the adjustment bracket are equipped with at least one distinguishing feature. In this way, an unambiguous assignment of the lateral legs of the adjustment bracket to a respectively assigned switch button and thus a high level of user-friendliness and safety can be achieved in an advantageous manner.
  • the adjustment bracket can expediently consist of two symmetrical, differently colored parts that can be connected to one another in a latching manner in the area of the upper web.
  • the field of application of the invention are blinds or external venetian blinds.
  • the drawing described below is based on an external venetian blind.
  • the basic structure and mode of operation of such arrangements are known per se and are therefore only mentioned below insofar as they can be of importance for understanding the invention.
  • the in Fig. 1 The external venetian blind shown contains a curtain 3 which can be raised and lowered, formed by slats 1 arranged in parallel one above the other and a lower end rail 2, which in the raised state shown forms a slat pack and via a lower passage slot into a building opening to be shaded in the area of the upper edge of a building opening attachable, box-shaped housing 4 is retracted, from the lateral ends of the curtain 3 associated guide rails 5 can go down, in which the slats 1 and the end rail 2 can engage with lateral guide nipples not shown.
  • the housing 4 can consist of several parts which are hooked into one another at their ends facing one another.
  • Lifting belts 6 and turning belts 7 indicated only by broken lines are provided.
  • the lifting belts 6 are passed through associated recesses in the slats 1 and engage the end rail 2.
  • the curtain 3 is suspended from upper support members 8, which can rest with their ends on associated holders on the upper housing wall.
  • the turning belts 7 engage on at least one longitudinal side, here on both longitudinal sides of the slats 1 or act according to Art a ladder herewith together.
  • a slat stack is arranged in a direction perpendicular to the hanging plane next to the stack of lamellas formed by the drawn-up hanging 3, i.e. opposite the Slat stack laterally offset drive unit 9 is provided.
  • the mentioned elements of the drive device 9 are in one over the length of the Drive device 9 received a continuous head strip 12 in the form of a downwardly open, U-shaped profile rail which can be attached to a downwardly protruding arm 13 of the support members 8.
  • the electric motor 10 is provided with an off switch 14 designed as a mushroom button, which by the curtain 3 when it reaches its the Fig. 1 underlying to a stack of lamellas raised end position can be actuated, so that there is practically an automatic limit switch.
  • a transmission element 15 which transmits the switching movement is provided, to which the curtain 3 runs up when it reaches its upper end position and which consequently actuates the off switch 14.
  • the electric motor 10 is placed in the head strip 12 in such a way that its off switch 14 protruding from one side points upwards.
  • the mushroom button forming the off switch 14 projects beyond the head strip 12, which is provided in the area of its upper web with a recess associated with the mushroom button forming the off switch 14, through which the mushroom button forming the off switch 14 can protrude.
  • the transmission element 15 is provided as a rocker placed on the head strip 12 two arms 16, 17 facing away from each other in opposite directions.
  • the rocker is placed so that it reaches over the curtain 3 with its arm 16 and the off switch 14 of the electric motor 10 with its arm 17.
  • the said rocker thus functions as a limit switch that switches off the electric motor 10 as soon as the curtain 3 dies has reached the desired upper end position.
  • a bearing block 18 is placed on the top of the head strip 12, on which the rocker is pivotably mounted.
  • the mounting of the two-armed rocker on the bearing block 18 is designed as a snap connection.
  • the bearing block 18 and the two-armed rocker are provided with bearing elements that can be snapped into one another with a degree of freedom of rotation.
  • the bearing block 18 is attached to a U-shaped retaining bracket 19 that is clipped onto the head strip 12 and encompasses it from above.
  • the lower ends of the lateral legs of the retaining bracket 19 are designed as spring claws encompassing the lower ends of the side walls of the head strip 12.
  • the retaining bracket 19, like the upper web of the head strip 12, is penetrated by the mushroom button forming the off switch 14 and is in accordance with this Fig. 2 provided with an opaque through recess 20 arranged over the above-mentioned recess of the upper web of the head strip 12 associated with the mushroom button.
  • an exchangeable compensating plate 21 can be attached to the underside of the arm 17 of the rocker assigned to the off switch 14. Depending on the motor used, different compensating plates 21 can be attached, which means that it can be used universally.
  • the compensating plate 21 can be releasably fixed on the associated arm 17 of the rocker.
  • a latching connection is provided for this purpose, which on the one hand has two spring legs 22 provided with latching teeth, which on a web provided on the other hand 23 can be snapped on.
  • the desired end positions of the curtain 3 can be set on the electric motor 10 and therefore the rocker forming the transmission element 15 only functions as an emergency stop switch.
  • the electric motor 10 is provided with the mushroom button adjacent to its off switch 14 and laterally offset relative to one another with respect to the width of the head strip 12 for setting the upper and lower end positions of the curtain 3. These are located next to the retaining bracket 19 and are accessible from above via a recess 25 in the upper web of the head strip 12. This recess 25 can be a larger recess 25 which is jointly assigned to the mushroom button forming the off switch 14 and to the switch buttons 24.
  • buttons 24, like the mushroom button forming the off switch 14, point upwards, but should be actuatable from below via an inspection opening in the housing 4, etc.
  • a U-shaped adjustment bracket that overlaps the head strip 12 from above is required to actuate the buttons 24 26 is provided, the lower ends of which can be reached from below.
  • the adjustment bracket 26 is clipped onto the head strip 12 in alignment with the switch buttons 24.
  • latching elements 27 which can be snapped onto the lower ends of the side walls of the head strip 12, preferably in the form of elastic spring claws, are provided at the lower ends of its side legs. From these actuating tabs 28 can go down, which can be grasped directly by hand or by means of a tool.
  • the upper web of the actuating bracket 26 is provided with sensing projections 29 associated with the switch buttons 24. Depending on which actuating tab 28 is pulled, one or the other switch button 24 is actuated.
  • the side legs of the actuating bracket 26 are clearly recognizable Distinguishing feature fitted.
  • the switch buttons 24 are usually colored differently.
  • at least the actuating tabs 28 of the adjustment bracket 26 are therefore also different, preferably colored in the same colors as the switch buttons 24.
  • the adjustment bracket 26, as shown in FIG Fig. 3 can be seen, consist of two symmetrical, differently colored halves 26a, 26b, which overlap each other in the area of the upper web and can be clipped together.
