Definitions

  • the invention relates to an awning, in particular a conservatory or weather protection awning, with the features specified in the preamble of patent claim 1.
  • Such awnings are known to have an awning curtain, a support frame with lateral guide rails for the awning curtain running in the direction of projection of the awning and end rails running transversely thereto for stationary mounting of the awning on a building and/or on supports.
  • a drop profile is provided, which is driven to be displaceable in the guide rails in order to extend and retract the awning curtain in and against the drop-out direction.
  • the fixed end of the awning curtain on the retracting side is held in a counter bearing.
  • the extended end position can be controlled by extending the awning curtain until it stretches and the associated increase in torque is used as a switch-off criterion.
  • the disadvantage here is that it changes over time the awning curtain lengthens so that the maximum extended position moves further forward in the direction of the drop and there is a corresponding risk that the drop profile will end up on the other side of a rain gutter. This would have to be compensated for by a corresponding correction of the position of the counter bearing for the fixed end of the awning curtain on the retracting side.
  • the invention is based on the object of further developing an awning in such a way that the effort involved in adjusting the awning is considerably reduced.
  • the front profile can, for example, move to a fixed, exact extension end position in a path-controlled manner, in which the counter bearing is then pulled along somewhat in the direction of projection according to the basic length of the awning curtain and the tension of the fabric is ensured by the spring force applied.
  • An elongation of the fabric that occurs over time can be compensated for without any problems, since the counter bearing is then pulled a little less far in the direction of failure due to the spring force and the fabric is still tensioned.
  • the above basic concept of the invention is applicable to various types of awnings.
  • a folding awning for example, in which the awning curtain is divided into strip zones like a canopy and attached to cloth support profiles that are displaceably mounted in the guide rails, the counter bearing can be formed by the cloth support profile that holds the fixed end of the awning curtain on the retracting side.
  • the counter bearing can preferably be formed by the winding shaft itself.
  • the awning fabric is fully extended, this can still move in the direction of failure against the spring loading be pulled a little to build up the fabric tension accordingly.
  • the winding shaft is then shifted a little less far in the direction of failure over time when it assumes the extended end position.
  • springs such as elastic compression or tension springs
  • a gas spring is particularly preferred for the application because of its compact design and advantageous response behavior.
  • the cloth support profiles are usually slidably mounted on carriages in respective tracks in the guide rails, with the spring loading, i.e. in particular a corresponding gas spring, acting on a stop on the carriage that displaceably supports the cloth support profile holding the fixed end of the awning curtain on the retracting side.
  • the spring loading i.e. in particular a corresponding gas spring
  • the awning curtain is held taut in its maximally extended desired position between the drop profile and the counter bearing with the spring loading force. A corresponding length compensation can take place at the same time.
  • the counter-bearing it is also possible for the counter-bearing to be positioned in a reference position by the spring loading when the awning curtain is not fully extended.
  • This has a rectangular support frame 1 seen from above, which is composed of lateral guide rails 3, 4 running in the projection direction A of an awning curtain 2 and end rails 5, 6 connecting their ends.
  • the awning housing 5 which is usually referred to as the awning housing 5 and houses the electric drive for the awning curtain 2
  • the awning is mounted on a building wall 7 via appropriate brackets (not shown), the opposite end rail 6 rests on Supports 8, 9, which are, for example, on a terrace 10 to be covered.
  • the awning curtain 2 is an awning fabric 12 which, with its end pointing in the direction of projection A, is fastened in a projection profile 11 which runs transversely to the direction of projection A and is driven in this direction so as to be displaceable in the guide rails 3, 4.
  • the awning fabric 12 is also divided into individual strip zones 13 like a canopy and fastened to a fabric support profile 14 with the edge of each of its zones 13 .
  • the displaceability of the cloth support profiles 14 in the guide rails 3, 4 is achieved by a rail arrangement, as in the 3 and 4 is shown in detail.
  • the guide rails 3, 4 each have a track 16 realized by inner profile webs 15—see in particular 3 - On, in each of which the cloth support profiles 14 carrying carriages 17 run on corresponding pairs of rollers 18 along.
  • the four rollers 18 of the two pairs of rollers per carriage 17 are rotatably mounted on a bearing body 19 of the carriage 17 .
  • the drop profile 11 and the cloth support profiles 14 are mounted at their ends 20 via a bearing axis 21 on the respective carriage 17 .
  • the drop profile 11 is connected via its carriage 17 to an endless toothed belt 22, which runs around the two ends of the guide rails 3, 4 via deflection rollers.
  • the part of the awning housing 5 lying deflection roller 23 is in the 3 and 4 recognizable with its square opening 24, in which a drive shaft connected to the electric motor drive of the awning engages in a rotationally fixed manner.
  • the retracting and extending movement of the awning curtain 2 described above can thus be accomplished via a corresponding reversing actuation of the deflection roller 23 .
  • the last fabric support profile 14' on the side of the awning housing 5 forms a counter bearing 25 for the fixed end 26 of the awning fabric 12 on the retracting side.
  • This counter bearing 25 is similar to the other fabric support profiles 14 on a carriage 17' so that it can be displaced parallel to the direction of projection A.
  • a gas pressure spring 27 is provided for spring loading of the counter bearing 25 counter to the direction of failure A, which acts with its piston rod 29 on a stop 28 of the carriage 17' and is counter-supported with its cylinder housing 30 on a fixed bearing plate 31 in the guide rails 3, 4.
  • the awning fabric 12 hangs loosely with its strip zones 13 downwards, so that no tensile force in the direction of failure A is applied to the fabric support profile 14' and its carriage 17'. Accordingly, the spring force of the gas pressure spring 27 acts to the effect that carriage 17 'and Cloth support profile 14 'against the direction of failure A in a defined position relative to the direction of failure A - so for example to the maximum extension length of the gas pressure spring or against a stop in the track 16 - are pushed.
  • the awning fabric 12 When extending the awning fabric 12 in the maximum extended position - as in the 4 and 6 shown - the awning fabric 12 is tensioned towards the end of the extension movement, with the fabric support profile 14' serving as a counter bearing 25 at the fixed end 26 of the awning fabric 12 on the retraction side being displaced against the spring loading by the gas pressure spring 27 compressing itself in the process. Its spring force thus provides for an effective tightening of the awning fabric 12 as well as a compensation for an elongation of the awning fabric in the direction of failure that occurs over time.
  • the abutment 25 is pulled more strongly against the gas pressure spring 27 in the direction of failure A when, for example, a path-controlled approach to a defined end position of the front profile 11 is in the extended state. If the awning fabric 12 is stretched over time and is therefore longer in the direction of failure A, the counter bearing 25 is pulled along less, as a result of which the elongation is compensated for and the awning fabric 12 remains taut as before.
