Abstract

Awning tensioner (10) comprising a first attachment means (18) for connection to a rigid fastener and a second attachment means (20) for connection to the awning, characterized in that the tensioning device (10) is formed of a plurality of rubber cords (12). is trained.

Description

The invention relates to a tensioning device for sun sails.

State of the art

For mounting sun sails different devices are known. In the case of awning or canopy arrangements in which a tarpaulin is mounted on a rotatable shaft in such a way that the tarpaulin is completely secured to the shaft by an edge, a drop profile can be arranged on the opposite edge of the tarpaulin, to which articulated arms engage. When the tarpaulin is unrolled from the shaft, the articulated arms pivot and span the tarpaulin between the ledge and shaft carried by them.

For larger areas, however, this type of awning is not suitable because the articulated arms sag too much and act on the fastening devices very large leverage.

Clamping devices are known ( DE 20 2005 001 875 U1 ), in particular for sun sails, in which at least one cable pull is fastened to a roll-up tarpaulin. The planetary shaft is rotatably mounted on two carriers and provided with a drive. The cable can be rolled up on a separate winding shaft. The separate winding shaft is coupled to the plane shaft. Both waves move synchronously during the winding or rolling of the awning.

By winding the cable on its own shaft forces acting on the cable are transmitted only to the winding shaft and not on the plane shaft. The tarpaulin shaft is thus free of compressive or tensile forces of the cables. This construction is especially suitable for larger awnings.

However, this training is prone to the occurrence of particular gusty winds in which the cable and / or the tarpaulin can be damaged.

Furthermore, a device for unfolding a membrane in space ( DE 10 2007 018 564 A1 ) known. The membrane is connected at the edge to a frame. A surface enclosed by the frame is enlarged by at least partially elastically bending at least one mast, which is part of the frame, until the membrane is deployed within the frame.

In terrestrial application of such a device, the only partially elastically deformable mast would run the risk of spontaneous wind load or the like. not withstand and break.

A disadvantage of the known tensioning devices for sun sails is that they are usually rigid and are not suitable to compensate for especially spontaneously occurring winds. As a result, there is a risk that the awning will beat wildly, causing damage to people or the awning.

The object of the invention is therefore to provide a tensioning device for sun sails available, which allows easy tensioning of a sun sail, it being ensured in the oncoming wind that the awning does not flutter uncontrollably.

Disclosure of the invention

It is proposed a tensioning device for sun sails, which is designed similar to an expander.

In this case, the tensioning device is designed in the form of an expander made of a rubber strand, wherein the tensioning device is arranged at its one end to a rigid attachment to which the awning is suspended, and arranged at its other end directly on the awning itself.

The clamping device is designed to be flexible by training as a rubber strand is clamped in such a way that it is stretched in its stationary length and thus undergoes a bias. In particular, the jig is stretched by about 50% of its resting length.

With rising wind the tensioning device then expands by approx. 100% up to 150%, so that the awning can inflate. Thus, the tensile load on the suspensions is derived "self-regulating".

The tensioning device in this case has a plurality of rubber straps, which cooperate as a rubber strand, wherein the individual rubber cords are threaded in each case in one piece by a perforated disc, wherein at each end of the tensioning device in each case a perforated disc is arranged. The respective ends of each rubber cord are then knotted together with, for example, crotch knots.

The clamping device has at its ends in each case a ring nut. These ring nuts are each connected to fastening devices, such as a shackle. The safety line in turn is on the one hand to the shackle, which is attached to the rigid attachment, attached and fastened on the other side to the shackle connected to the awning. This ensures that the awning is moved uncontrollably.

The tensioning device according to the invention for sun sails has the advantage that the awning can be optimally tensioned by the flexibility of the tensioning device and on the other hand by the formation of the tensioning device comparable to an expander this has the function of a "wind compensator", since the tensile load in particular spontaneously occurring wind derived on the suspensions self-regulating.

The tensioning device acts as an elastic suspension of the awning to the post. The arrangement on the awning, which can inflate in the wind, reduce the horizontal forces and it is provided a self-regulating, less wind-prone or the wind compensating construction.

The tensioning device, in an advantageous embodiment of the invention as a securing element further on a safety lanyard on. If the rubber strands are overloaded and if they break or break, the safety line will catch the awning. This additionally prevents the awning from beating around wildly, causing damage to people or the awning.

An additional backup is thus made possible by the safety leash.

Further advantages and advantageous embodiments of the invention are the following description of the figures, the drawings and the claims removed.

An exemplary embodiment of the solution according to the invention will be explained in more detail below with reference to the attached schematic drawings. It shows:

1 shows a clamping device in the side view and

2 shows a clamping device in cross section.

In 1 is the tensioning device 10 in the form of an expander made of rubber straps 12 trained, which form a rubber strand. The tensioning device 10 is at its one end to a rigid attachment to which the awning is suspended, arranged and arranged at its other end directly to the awning itself.

The tensioning device 10 is doing the training with the rubber straps 12 being designed to be flexible is clamped in such a way that it is stretched by approximately 50% of its static length and thus experiences a preload.

When the wind rises, the tensioning device expands 10 then about 100%, so that the awning can inflate. Thus, the tensile load on the suspensions is derived "self-regulating".

The tensioning device 10 has a variety of rubber straps 12 on, in one piece through a perforated disc 14 be threaded, with at each end of the tensioning device 10 one perforated disc each 14 is arranged. The respective ends of each rubber cord 12 are then knotted together with cross knots, for example.

The tensioning device 10 has at its ends in each case a ring nut 16 on. These ring nuts 16 are each with fasteners, such as a first shackle 18 for attachment to a rigid attachment and a second shackle 20 for attachment to the awning, connected.

The tensioning device 10 In an advantageous embodiment of the invention as a securing element further comprises a safety lanyard 22 on. If the rubber strand is overloaded and if it snaps or breaks, the safety leash will catch 22 the awning on. This prevents the awning from beating wildly, causing damage to people or the awning.

The safety line 22 in turn, on the one hand to the shackle 18 attached to the rigid attachment and attached to the other on the other side of the shackle 20 attached to the awning attached. This prevents the awning from being moved in an uncontrolled manner.

2 shows a cross section through the clamping device 10 , Here are the rubber cords 12 represented, which together form the rubber strand and thereby the flexibility of an expander for the tensioning device 10 enable. This property causes the function of the tensioning device as a "wind compensator".

All in the description, the following claims and the drawings illustrated features may be essential to the invention both individually and in any combination.
