Definitions

  • the invention relates to a slatted roof with a horizontally aligned frame in which a number of slats can be pivoted by more than 90° between a position closing the slatted roof and an open position, with a synchronization device synchronizing the movement of all slats and in at least one of the slats is provided with an electric drive motor, the motor head of which is fixed to the frame via a bearing element with a bearing block and the output shaft of which is coupled to the driven slat.
  • Such a slat roof is from WO 2019/186213 A1 known.
  • Such a solution has the advantage that the motor can be placed unobtrusively inside one of the slats.
  • the transmission of the rotation of the driven slats to the other slats takes place via a suitable gear, for example by means of gears, push or pull elements.
  • the slats can be pivoted from a horizontal position in which they overlap one another to form a closed roof to an open position, it being desirable to be able to pivot beyond the vertical position to allow the slats to be tilted in different directions be able. It has now been shown that when driving over the dead center, which is usually due to the vertical position of the Lamella is defined, the combination of all lamellae carries out a noisy load change due to the momentarily reversing forces in the drive train. Due to the not inconsiderable mass of the slat assembly and the large sound-emitting surfaces, the user perceives this as disruptive or even threatening when this event occurs.
  • Examples of other slat roofs are, for example, from FR 2 987 061 A1 , the EP 3 438 371 B1 or the DE 10 2016 117 772 A1 known.
  • the object of the present invention is to improve a slatted roof of the type mentioned at the outset in such a way that the noise generated by the slatted roof during load changes is reduced.
  • the object is achieved by an awning of the type mentioned in which the bearing block and the bearing element are coupled without play via a non-positive, positive or material-locking connection and/or the output shaft is connected to the slat via at least one non-positive, positive or or cohesively formed connection point is coupled.
  • the solution according to the invention offers the advantage that the noise behavior when driving over the dead center is improved. Undesirable teetering and jerky movements are also avoided.
  • Each individual measure to reduce or avoid the play between friction-locked elements between the bearing block fixed to the frame and the driven plate is suitable for achieving an improvement in the noise behavior, with the specialist being able to decide with this proviso at which point he considering the costs, technical functionality as well as installation and maintenance specifics, which individual measure is taken.
  • These measures can include, for example, the one-piece formation of previously separate elements or the welding, soldering, gluing, screwing, form-fitting connection, pressing or bracing of adjacent elements lying in the power flow, or also in the omission of certain parts in the power flow to avoid this consist of connection points.
  • the clamping of two adjacent elements can be solved in such a way that a first element is designed in several parts and the other element is clamped between clamping surfaces on the parts of the first element, for example by means of clamping screws.
  • the bearing element is designed in one piece with the motor head or is pressed, welded, glued to the motor head as a separate element or is inserted via a play-free fit.
  • the bearing block has proven to be particularly advantageous for the bearing block to have at least two clamping elements, between which the bearing element is clamped.
  • a further advantageous measure relating to the bearing block can be that the bearing block is connected to the frame via a form-fitting connection, for example in such a way that the bearing block is guided without play in an undercut groove which is arranged in the frame perpendicular to the axis of rotation of the slats is.
  • a screw connection is usually sufficient.
  • Another part of the powertrain that has not received any attention in terms of noise reduction is the output area of the engine.
  • any existing reduction gears can be optimized with regard to play, but this is usually not within the reach of the designer of a slatted roof.
  • the following measures can help to reduce play in the area of the engine output.
  • the driver can also be designed in several parts and clamped to the output shaft.
  • the driver can preferably be coupled to a motor housing, which is fitted form-fittingly in the lamella without play, or directly to the lamella via a connection point formed with a force, form or material connection.
  • a motor housing which is fitted form-fittingly in the lamella without play, or directly to the lamella via a connection point formed with a force, form or material connection.
  • the lamella is provided with a front cap on its motor-side front end. This measure, which is known as such, contributes less to noise reduction, but allows the lamella to be designed as a hollow profile for accommodating the drive motor.
  • the motor housing or the lamella is pivotably mounted on the motor head and/or on the bearing element via a pivot bearing. It is preferably mounted on the bearing element via the side part/front cap mentioned above.
  • In 1 is a driven slat 10 of a slat roof 100 (see 3 ).
  • the slatted roof known as such is not shown here and is only presented briefly. It essentially consists of a rectangular frame that is raised on supports and/or attached to the side of parts of the building or walls.
  • a drive motor 14 is provided which, in the exemplary embodiment presented here, is mounted on the frame with a motor head 16 and protrudes into the driven lamella, which is designed as a hollow profile.
  • the firmly mounted motor head 16 has the advantage that the connecting cables can be guided into the motor without any movement and are not subject to any movement when the slats are pivoted.
  • the motor 14 protrudes far into the lamella 10 with a tubular body 18 designed to be non-rotatable with respect to the motor head 16 .
  • a motor housing 20 is rotatably mounted on the motor head 14/tube housing 16 and is designed as a hollow profile, e.g. in the form of an extruded profile. This sits in the direction of rotation in a form-fitting manner in the lamella 10, which is also designed as a hollow profile, with insertion being made possible by the corresponding shape of the outer profile of the motor housing and the inner profile of the lamella 10.
  • the lamella 10 is screwed to a front cap 22 at its front end.
  • First fastening screws 24 engage in screw channels 26 in the hollow profile of lamella 10, while second fastening screws 28 are screwed into screw ducts 30 in the hollow profile of motor housing 20, so that a combination of lamella 10, end cap 22 and motor housing 20 is formed.
  • This composite is by means of a bearing ring 32 which fits into an opening 34 in the end cap 22 is used, rotatably mounted on a bearing element 36.
  • the bearing ring also seals the interior of the slats against the ingress of moisture.
  • a pivot pin 38 is provided on the end cap 22, which is connected by means of connecting rods (not shown) to pivot pins 40 on end caps 42 of the non-driven, entrained slats 12, so that a slat composite formed for giving away together is created.
  • the bearing element 36 is designed here as a possible example as a component designed separately from the motor head 16 , but it can also be designed in one piece with the motor head 16 .
  • the bearing element 36 is designed with an insertion pin 44 on the motor side, a cylindrical middle region 46 and a bearing pin 48 .
  • the central area has a cylindrical outer surface 50 which, together with an inner surface of the bearing ring 32, forms a slide bearing.
  • the motor-side insertion pin 44 is designed as a polygonal profile and is inserted into an opening in the motor head 16 with a corresponding, low-backlash opening cross-section.
  • the bearing element 36 is by means of two screws 52 which engage through axially aligned bores 54 in the central area 46 and are screwed into threaded bores in the motor head 16. This results in a play-free attachment of the bearing element 36 to the motor head 16 even when the fit between the motor-side insertion pin 48 and the opening in the motor head 16 is subject to play.
  • the bearing pin 48 protruding beyond the end cap 22 is fixed in a bearing block 56 which is designed here in two parts.
  • the end of the bearing journal 48 is clamped between a clamp 58 and a lower part 60 of the bearing block 48 with the aid of clamping screws 62 .
  • the bearing block 56 itself is screwed to the frame (not shown) and for this purpose can be guided in an undercut groove, e.g. in a dovetail groove.
  • pivot pins 38, 40 can also be seen, which are connected to one another via push rods (not shown), with a single continuous push rod with corresponding bearing openings for connecting all the slats of the Lamella roof 100 can be provided so that all slats 12 are pivoted together with the driven slat 10 when the motor 14 is driven.
  • the slats 10, 12 form a rainproof roof that protects against rain in that they each have a drainage channel 64 on one longitudinal side and a roof-like projection 66 on the other longitudinal side, which, when the slat roof 100 is closed, the drainage channel 64 of the adjacent slats 10 12, 12 so that incident precipitation can be safely drained into the drainage channels 64 and thence into lateral drainage channels (not shown) in the frame.
  • the roof-like projections 66 also form a stop for the closed position of the lamellar roof 100 by resting on the lateral walls 68 of the drainage channels 64 of the respective adjacent lamella 10, 12.
  • a further stop (not shown) can be provided.
  • a driver 70 sits on an output shaft 72 of the motor 14.
  • the driver 70 is screwed onto the output shaft 72 with a clamping screw 74.
  • the driver can also be divided, in which case the output shaft can be clamped between the parts by means of a suitable clamping mechanism. If the installation or a desired possibility of dismantling allow it, the driver can also be designed in one piece with the output shaft or can be welded, glued, pinned or pressed to it.
  • the torsionally rigid connection of the driver 70 to the motor housing 20 or directly to a suitable internal cross section (not shown) of the lamella 10 can be effected by radially aligned screws (not shown) which form a cylindrical wall (also not shown) as part of the structure of the motor housing 20 or penetrate the lamella 10 and are screwed into radial threaded bores 76 .
