Definitions

  • the invention relates to an awning with a height adjustment for the deflection point of a tensioning cable on at least one post with a tensioning device over which the tensioning cable is guided, the end of the tensioning cable being fixed at a fastening point.
  • the DE 20 2008 042870 A1 shows a weather protection in which at least one support is designed to be height-adjustable in that the post is designed to be telescopic, the tension cable of the awning tensioned there being fixed to the ground at its end by a tension spring.
  • the cable tension changes significantly when adjusting the height and the range of height adjustment is severely restricted.
  • the WO 2013/080234 A1 shows an awning in which the free end of the tensioning cable is hung on a holder which is height-adjustable on a rail on the post.
  • the system does not show any tensioning device in the height adjustment area, so that no continuous adjustment of the extension length of the sail is possible.
  • the DE 10 2011 112523 A1 shows an awning with a single deflection roller that can be fixed at different heights on a post.
  • a fastening of the end of the rope in the area of the post is not provided, nor is there a tensioning device with length compensation, which is provided here by a counter-pull system.
  • the deflection pulley of the tensioning cable on the post is adjustable in height and the cable is routed to a tensioning device with length compensation, so that the extension length of the awning can be changed by simply turning the winding shaft.
  • the height adjustment has an effect on the extension length, or the curtain can only be retracted at a certain height.
  • the operating forces for the height adjustment in these known systems are very high in at least one direction, because the tensioning force of the tensioning cable on the deflection pulley generates a reaction force acting parallel to the post.
  • the object of the present invention is to improve an awning on at least one post with a tensioning device with a height adjustment in such a way that the mutual influence of the extended length of the sail and the height adjustment on the post is reduced.
  • the object is achieved by an awning of the type mentioned at the outset, in which the attachment point is formed at a point that is at an identical distance from the deflection point in all positions of the height adjustment.
  • the solution according to the invention offers the advantage that the supply of tensioning cable within the post and the tensioning device no longer changes or only changes to a minimal extent. As a result, the cable tension remains essentially constant and the extension length can be adjusted at all altitudes.
  • the height adjustment is formed by a multi-part post consisting of a base element anchored to the ground and a movable post element that can be adjusted for this purpose the attachment point, the deflection point and the tensioning device are arranged on the movable attachment element.
  • the rope is stretched by a tensioning device, but its end is not fixed to a stationary part, even if the split post is preferably designed to be telescopic in a similar or different way.
  • an awning provides that the height adjustment is formed by a height-adjustable carriage arranged on the post, on which a deflection roller is arranged at the deflection point of the tensioning cable and at a certain distance from this the attachment point for the end of the awning Tension cable is provided.
  • the carriage is slidably mounted on a guide within the post and the tensioning cable is guided outwards through a slot in the post, or the carriage is slidably mounted on a guide on the outside of the post and the tether and the free end of the tether are diverted through an exit opening in the post to the carriage.
  • the guide direction is preferably essentially perpendicular to the clamping force, with a low-friction guide being able to keep the actuating force for the height adjustment low even with high clamping forces.
  • a further, particularly preferred embodiment of the sun sail according to the invention provides that the tensioning cable is guided in a first direction to the deflection roller and the end of the tensioning cable is guided in an opposite direction to the attachment point.
  • aids to support the actuation can be dispensed with.
  • Such aids to support the user when adjusting the height are, for example, reduction gears, such as pulley blocks, which extend the actuation path, or motorized supports. The omission of these simplifies not only the operation but also the design and manufacturing effort for the sun sail.
  • An exemplary, structurally simple to implement the measure described above in an awning can provide that a first exit deflection pulley for the tension cable and a second exit deflection pulley arranged coaxially thereto for the end of the tension cable are arranged at the outlet opening in the post, wherein the exit pulleys deflect the tether and the end of the tether down towards the carriage, and below the carriage another lower tether pulley is provided for the tether on the post, which rotates the end of the tether 180° to the carriage with the attachment point redirects back.
  • the carriage is preferably guided on the post in such a way that the carriage is displaceably mounted on a guide rail which extends parallel to the post below the outlet opening.
  • a guide rail which extends parallel to the post below the outlet opening.
  • the height can be adjusted using a simple handle that is connected to the deflection roller of the deflection point or can be connected to it at different distances from the deflection roller of the deflection point.
  • the handle can be connected directly to the carriage of the deflection roller of the deflection point.
  • An embodiment of the invention is particularly preferred in which the handle is guided below the deflection roller of the deflection point in the guide rail separately from the carriage and with a first clamping device at the end of the tensioning cable, preferably in the area between the lower deflection roller and that of the outlet - Deflection pulley is fixed detachably.
  • the handle has a second clamping device, with the aid of which the handle can be clamped at the end of the tensioning cable in the area of the other strand, which is not clamped by the first clamping device, between the lower deflection roller and the handle and/or or can be clamped to the guide rail.
  • the height adjustment can be locked by clamping both strands of the tensioning cable or by clamping the handle in the guide rail.
  • the carriage has a third clamping device, by means of which it can be clamped to the guide rail and/or to the area of the end of the tensioning cable that extends between the exit deflection roller and the lower deflection roller .
  • a structurally preferred embodiment of the clamping devices can provide that they are formed by clamping screws, the shaft of which can be clamped with its end against the respective area of the end of the tensioning cable or against the guide rail.
  • clamping devices such as clamping levers that act on a cable bushing.
  • a drive with a drive shaft is provided for the adjustment of the carriage, which is connected in a torsionally rigid manner to the lower deflection roller.
  • the drive has a removable hand crank or an electric drive motor.
  • a post 10 of an awning is shown, as it is used at a guy end of the awning.
  • a tension cable 12 is led out of a deflection device 16 at a deflection point 14 and is hung with a snap hook 18 for hanging in an eyelet in an end of the awning, which is generally triangular in shape.
  • the position of the snap hook 18 shown corresponds to the extended end position of the awning, not shown, ie the tensioning cable 12 is pulled back with a maximum length of cable stored in the post.
  • the rope supply is made possible by a pulley system 20 arranged inside the post 10 with upper and lower pulley wheels 22, 24 movable relative to one another, which at the same time has a tensioning device 26 (see FIG 3 ) forms with at least one helical spring 28 subjected to tension.
  • This jig 22 with a supply of rope keeps the tension rope under tension in all extended positions and thus tightens the awning, the extension length of which can be changed by actuating a winding shaft, not shown.
  • the tension cable 12 is via a first deflection pulley 30 (see 3 ) is deflected at the deflection point 14 in a direction parallel to the post 10, the deflection roller 30 being mounted on a carriage 32 which is linearly movably guided in a guide rail 34 which is attached to the outside of the post 10.
  • a cover 36 protects the idler pulley 30 and prevents the user from touching it.
  • the tension cable 12 is deflected via a first exit deflection pulley 38 at an opening 40 in the post into its interior and guided over the pulley system 20 .
  • the pulley system of the exemplary embodiment shown is only to be understood as an example; in particular, several pulley systems can also be provided in series.
  • one end 42 of the tension cable 12 is connected via a second exit deflection roller 44 which is arranged coaxially with the first exit deflection roller 38 .
  • the end 42 of the tensioning cable is guided downwards by the second exit deflection roller 44 parallel to the tensioning cable 12 in the guide rail 34, being deflected upwards by 180° past the carriage 32 to a lower deflection roller 46 and from there to to an attachment point on the carriage 32 where it is fixedly connected to the carriage 32.
  • the lower deflection roller 46 is rotatably mounted in a stationary manner on the guide rail 34 or directly on the post 10 .
  • This arrangement enables a height adjustment over the length of the guide rail 34, with the deflection of the end 42 of the tensioning cable 12 and its attachment from an opposite direction in relation to the feed of the tensioning cable to the first deflection roller 30 being able to achieve a cancellation of the tensioning force. So it is possible to adjust the height with little effort, which only has to overcome the frictional forces of the guide.
  • the extension length of the tether does not change, or only minimally, when the height is adjusted, since the end of the tether 42 is always fed back or forth by a suitable length due to its attachment to the carriage.
  • a simple handle 48 which is 1 is shown. This is also movably guided in the guide rail 34, with no direct connection being provided between the carriage 32 and the handle 48 in the exemplary embodiment shown. As an alternative, however, the handle 48 can also be configured together with the carriage 32 .
  • the handle 48 is locked relative to the carriage 32 by means of one of two clamping devices 50, 52 which can be clamped by means of two grub screws against a respective strand 58, 60 of the end 42 of the tensioning cable 12.
  • the handle 48 can be moved freely to the carriage 32, although the adjustment path of the height adjustment can be restricted if the distance selected is too large.
  • a first clamping device 50 acts with the shank of the grub screw on strand 58 of tensioning cable end 12, which runs between lower deflection roller 46 and the attachment point of tensioning cable end 42 on carriage 32, while the second clamping device 52 acts on strand 60 of tensioning cable end 42 running in the opposite direction between the lower deflection roller 46 and the second exit deflection roller 44 acts.
  • one of the two clamping devices can also interact with the guide rail 34 in order to lock the handle 48 in place.
  • the carriage 32 can also have a third clamping device (not shown), which either acts on the run 60 between the lower deflection roller 46 and the second exit deflection roller 44 or can be clamped against the guide rail 34 .
  • a hand crank 148 can be provided to reduce the operating forces.
  • a hand crank 148 is provided, which is connected to the lower deflection roller 46 in a torsionally rigid manner with its crankshaft, for example by means of a polygonal plug connection.
  • the translation of the crank as such already ensures the desired reduction in the operating forces, but if necessary a gear stage can also be interposed.
  • the crank can have a detent, by means of which it can be blocked in the direction of rotation. As a rule, however, this is not necessary due to the sufficiently high frictional forces in the system.
  • the crank can be detachable.
