  • the present invention relates to a weight-controlled wind pressure relief system with a fabric surface or tarpaulin mounted on at least one side on a stationary bearing, which is connected to a pull rope.
  • Sail constructions are often used for shading and rain protection.
  • sun sails are used, which are clamped between attachment points. It is important in the use of solar sails to ensure that there is always sufficient tension, as otherwise water accumulates when the rain starts to rain.
  • the basic voltage used must not be too high, because when the wind starts, high additional forces act on the anchors of the awning. These additional forces may cause damage to the awning and anchors.
  • awnings are according to conventional design very vulnerable to wind pressure and of course other extraneous pressure and tensile loads such as rain and hail. For this reason, tightly tensioned, non-roll-up awnings with a very high basic tension are mounted between these very costly anchorages and bearings, in order to be able to withstand the aforementioned weather effects without damage.
  • roll-up and unrollable structures are known.
  • the tensioning cables pulling the sail from the shaft are stretched and tightened over an abutment and the rope which is freed is still wound up manually and fastened to hooks.

Especially in strong wind and rain, the forces acting on the awning can be compensated accordingly quickly and need neither manual adjustment nor burden them further mechanical systems.
  • the system works independently of the weather and in particular of wind, rain and outside temperatures, evenly and unaffected. It also causes the tense fabric surfaces or tarpaulins, especially in strong wind and heavy rainfall, the yielding forces in material gentle manner for short-term pressure relief can be given, without losing the tension and gently return to pressure automatically immediately return to their desired position.

  • the tube must be employed at an angle to the fall line of the connecting cable such that in the respective uppermost Hubwegposition of hanging freely on the connecting rope weight still no contact of the weight takes place to the tube. Otherwise, from the moment of contact, the required force would increase significantly via friction and angular lever forces, which would hinder the effort required, for example, when winding up the fabric surface onto a shaft or during a pressure relief situation.
  • the freely suspended visible weight has another safety advantage, because it indicates the load condition of the sail by wind pressure and the limit of the possibility of wind pressure relief, because the length or height of the respective stroke of the weight in relief situations is a clear indicator.
  • the load limit or at least the limit of the relief possibility of this embodiment according to the invention of a solar sail installation is indicated.
  • the connecting cable and the separate stationary mounted pulley have a further important function with respect to the safety of the invention, because the pull rope should tear once by material break, etc., the weight would fall freely to the ground.
  • the possible path between the separate stationary mounted pulley for deflecting the connecting cable and the loose pulley block is adjusted so that it corresponds to the set stroke of the outside hanging weight. This can be done both by the corresponding positioning of the separate stationary mounted pulley, as well as by the rope length adjustment of the pull rope, which runs in the pulley.
  • the loose pulley block is provided with rollers in such a way that it can roll along the inner side of the inclined tube towards the bottom and is kept at a distance therefrom. Not only the force of gravity, but also the targeted positioning of the attachment of the traction cable and the connecting rope cause the traction rollers and thus the loose pulley block to be pressed constantly against this side of the inner wall of the pipe, since the tension and traction force are affected by this angle of attack the weight, which acts on these rope components, now partially acts in a transverse force directed against this side of the Rohrin- nenwand.

  • the cheeks of the loose pulley block are so wide dimensioned and widened that they are always on the possible train route of loose pulley block between the two cables and sliding along these are approximately linear and protected against rotation.
  • the cited safety rope in this embodiment of the invention is a further cable which runs next to the connecting cable and has the same construction but which is installed in parallel and which is mounted as a separate connection between the loose bottle tensile block and the weight. It should be able to assume its function alone in the event of a cable break of the connecting cable. Thus, the functions of safety rope and connecting rope are interchangeable.
  • the brake body previously mentioned as an additional guide element and fastened to the loose bottle block has a number of functions within the inventions. In general, it serves in conjunction with the air in the tube or a liquid as an additional speed-damping brake with respect to the falling speed of the weight when sinking back to a previously held, for example, in a relief situation of the awning increase in weight. It is particularly effective in this case if the tube is closed at the lower end and the tube is filled with a liquid through the openings. The level should be at least high enough for the brake body to hit the fluid before the weight reaches a supposed head height of a person below it.
  • the brake body Since the brake body is formed so that it occupies most of the pipe cross-section, this displaces, swirls and accelerates the liquid flowing around it during immersion and further movement in the liquid, which must flow past it. The forces required for this slow down the draw weight, but without significantly reducing the basic tensile force of the weight. The reduction of the fundamental tensile force is limited exclusively to a negligible value of the weight of the displaced liquid.
  • the tube In order to drain the liquid and to regulate the level, the tube has at its lower end a valve to be opened for this purpose.
  • the liquid When using a liquid, the liquid should preferably be enriched with antifreeze. All constituents of the invention which come into contact with the liquid should preferably be made of a stainless steel which is resistant to corrosion by the action of water,
  • the amount of this braking effect depends on how high the ratio of the cross-sectional area covered by the brake body to the uncovered cross-sectional area of the tube is.
  • the brake body as described above, can move up and down the pipe, but in terms of its simultaneous use as an additional guide element for the loose pulley block and a related small distance of its edges to the pipe inner wall can reduce its cross-section by his body additional cutouts for a larger and faster passage of liquid are introduced. In another embodiment of the brake body this covers the entire free cross-sectional area of the tube.
  • the edges of the brake body facing the movable penetrating parts and the pipe inner wall are equipped with sliding or sliding materials on it, such as rubber-like plastics, spongy porous materials or also brush-like attached fibers.
  • the brake body on the one hand seals the air space inside the pipe above him against the air space of the pipe under him at least so far that the sliding friction associated therewith during up and down movements of the brake body neither damages the sliding materials used, nor causes a high friction loss in relation to the tensile force of the draw weight.
  • the train weight added a share of weight, which compensates for the tensile force in the amount of the average friction loss again.
  • the brake body causes the air alone between each of it and the closed end of the pipe to brake its movement during a rapid upward or downward movement of the brake body, since the air must press against its rubber lips or brush fibers, for example. Since air is highly compressible, the braking effect starts dynamically. This causes that in a wind pressure-related relief situation and the associated sudden lifting of the weight no abrupt stop takes place at the end of the available stroke, but by the increasing pressure drop in the lower end of the pipe creates an increasing suction force, which causes an increasingly dampening braking effect. When falling back of the weight after the relief situation, this increasingly damping braking effect by the then increasing in the lower end of the tube and standing against the brake body over- pressure generated.
  • an additional air outlet must be set to reduce or increase the braking effect.
  • the brake body can be mounted at different positions and also on other components of the invention within the tube.
  • the brake body must, if necessary, have corresponding cutouts for the passage of movable components, allow the free flow of the movement of the invention components necessary according to the invention, and execute the corresponding pulling movements.
  • a further embodiment of the invention shows a solution which offers a solution in particular as a design for public spaces. For security reasons and due to the threat of vandalism or a misuse of a freely accessible and externally attached train weight another solution is much better suited here.
  • the weight is housed inside the tube and is connected there to the pull rope or loose pulley block of a pulley system. It is important that the weight can not beat and rattle on the inner wall of the pipe. It is therefore guided without friction at a distance to the tube inner wall.
  • this object is also achieved by a spacer in the form of a roller carriage.
  • This roller carriage can, as shown here, in approximately identical, but without pulleys correspond to the loose pulley block shown in the same figure.
  • the weight is as well as the loose pulley block about centric with the roller carriage positively and positively connected and is thus guided linearly by the voltage applied in each case approximately on the pipe inner wall rollers along the pipe inner walls with a distance from the pipe inner wall.
  • Another advantage of this design is that these tubes can also be placed vertically because they do not require an angle that allows a hanging weight the required free stroke.
  • the stroke of the weight can be shortened while maintaining the same tensile force on the traction cable, that the number of Um- increases steering between fixed and loose false train block, while at the same time the severity of the attached train weight is increased in accordance with this increase factor.
  • a separate and significantly wider separate space is created in this solution below a pipe that is only relatively short and open at the bottom, which has the space for a multiply translated pulley block and its respectively required pull path, in which case a considerably wider one and especially heavier weight fits.
  • the weight is connected through the lower pipe opening and a room access to the loose pulley block or to the pull rope.
  • the tube is rigidly connected to the walls of the separate room underneath and if the body of the separate room is designed as a kind of freestanding pedestal or base, no further anchoring of the pipe is required.
  • the separate room as a base with the tube on it can then be positioned freely on the ground and set up without further anchoring as a fully functional unit.
  • the suspended weight minus its tensile force delivered to the fabric tension on the tension cable, acts completely as a vertically acting weight force on the body of the separate space formed as a base.
  • This embodiment is particularly advantageous in the example application for overvoltage with an awning for shading outdoor seats of restaurants in urban streets.
  • the separate room could be combined in a comparable sizing with a conventional concrete raised bed container and appear as such.
  • the general advantage of the invention is particularly clear, because the pull rope of the sun screen always under pressure even under pressure from wind or rain a relatively low base voltage acts as a transverse attacking tilt or leverage on the pipe are. Rigid anchoring of the pipes and other bearings is not required by far for the clamping of the fabric surface, as would be the case, in particular, in the case of tightly braced or in the case of installations without a relief system.
  • solar sails are also often installed as permanently installed protective installations and canopies thanks to the free installation of their insert bearings on poles, pipes and posts.
  • This type of roofing is particularly often provided as protection against sun and rain in kindergartens and their outdoor playgrounds and sandboxes, as well as paddling pools for children in public bathing establishments.
  • the invention in an embodiment with constantly tense fabric or tarpaulin their advantages play. Because of these permanent tensions, in the case of conventional installations, due to the static forces and restraining forces which also withstand storm forces, it is very costly to invest in the strong anchoring and tension required for this, without actually providing protection against a complete material breakage.
  • the traction cables by heavy weights in the tubes are indeed under a higher base tension, as this would be necessary for rollable systems set, however, the strong wind peaks are intercepted relieving by the relief movement and the fabric or tarpaulin is then back to its state of tension withdrawn.
  • the invention has the further advantage not yet described separately, that they are excellent especially in very large and especially with up and unrollable surface tension, in which the fabric surfaces are mounted rollable on a winding shaft and where distances of over 10 meters are free to span can be used. Because the required constant traction, which increases with the length of each free to be clamped surface is simple and inexpensive by means of appropriate weights practically almost arbitrarily increased. Due to the robustness and simplicity of the invention, there are many other possibilities of application. This also applies, for example, to the bracing of vertical fabric surfaces or foils and tarpaulins, which are used as advertising spaces in temporary outdoor use as construction site signs or advertising transparencies.
  • the invention is also outstandingly suitable for a variety of applications in the architectural field and in normally fixed bracing installations of fabric and tarpaulin surfaces, such as canopies, protective roofs or temporary installations on open-air stages.
  • the load limits are significantly increased by wind pressure for a material breaking that would otherwise occur if these load limits at the anchors or tense surfaces exceeded. This is prevented in an installation according to the invention characterized in that at peak loads occurring, such as a storm gust, in the static usually the breaking point is reached, takes place at this point a short-term relief.
  • the weight used for bracing must be adjusted by its severity with a tensile force, which corresponds precisely to this load limit to material fracture.
  • the invention is an excellent solution for the diverse requirements and arrangements as sun sails for shading and as rain protection. Even within an equipped with wind sensors and automatically rolled up to a motorized shaft system, the invention clearly shows advantages over existing solar sails systems.
  • the set value for wind pressure in the sensor required for the roll-in command can be set much higher, since peak loads due to wind pressure not as usual tug on the material or lead to material breakage before the sail is retracted automatically, but always intercepted by the relief without the relieving fabric surface starts to flutter or hit, as this constant under the damped tension of the weight stands.

Abstract

L'invention concerne un système de neutralisation de la pression due au vent, commandé par un contre-poids, comprenant une surface de tissu (1) ou une bâche, qui est liée avec un câble de traction (2), et qui est montée, au moins d'un côté, à un palier fixe (26). Le câble de traction est précontraint au moyen d'un contre-poids (9), de sorte qu'une force de traction constante est exercée sur un parcours de levage. Le système de neutralisation de la pression due au vent s'adapte ainsi, de manière autonome, aux conditions météorologiques extérieures, notamment au vent et à la pluie. Les forces agissantes peuvent être rapidement équilibrées, en conformité avec lesdites conditions, et ne nécessitent aucun réglage manuel complémentaire.
