  • the present invention relates to protective roof according to the preamble of claim 1, 10 and 24, and a method for protecting vines according to the preamble of claim 20.
  • Hail or frost often leads to significant yield losses in vineyards.
  • late frosts or hail trains which are embedded in a storm front, can result in significant yield losses, with hail of 10 to 90%, s.
  • Late frost can produce the same devastating effects. Late frost is used when a short but comparatively extreme cold snap occurs at a time when the vines begin to drive out after the winter, and are then "in the juice". Late frost can rarely occur in February or March, but often in April or later, until May.
  • An example of late frost is described in the "Schweizerische Zeitschrift für Obst- und Weinbau", 22/12, p. 7 in the article "Ejected Vines - Possibility or Self-Education”. The late frost described there took place on May 18, 2012, which was preceded by an earlier late frost from Easter Monday 2012 - both times the temperature in the vine area had fallen to -5 ° C.
  • Late frost is a transient phenomenon, in contrast to winter frost, which can take days or weeks in the seasonal context.
  • Late frost can occur as "freezing frost” or “wind frost”, with radiating frost as a result of heat losses from the earth's surface in dry, calm air and clear Sky at night and wind frost is described as a result of relatively rapid influx of cold air masses, s. the magazine “Vine &Wine” 4/2914, in the article “So that the vines do not freeze off", p.22. Remedy against late frost, especially against radiation frost, to create according to "vine &wine” heaters such as heating candles (stop-gel candles) or heating wires, with vineyards in Australia were so protected against temperatures of - 6 ° C.
  • Vines are mainly pulled on a scaffold, whereby the growing on the frame of vines are cut several times and harvested.
  • the framework may consist of vertical posts connected by horizontal wires supporting the growing vine branches.
  • the cutting and harvesting is done by machine, which is why the frameworks are arranged in rows that form lanes through which the cutting and harvesting machines can travel.
  • a retractable, pneumatic protective roof is provided for the covering of vine, can not be damaged by hail, since the STE Henden structure under operating pressure chambers form an elastic surface which cushions the impact of hail grains ⁇ harmless.
  • the retracted pneumatic canopy can be quickly and easily extended and retracted by the means for pulling just as quickly and easily, and it does not disturb the vine in the retracted state, neither by Shading the vine still by obstructing the care or harvest of the vine.
  • the protective roof in particular if it is a pneumatic canopy, can be combined in arrangements to protective roofs, large and largest wine growing areas can be protected efficiently and at low cost, with the constant r- schaff the protective roof allows protection at all: even with smaller Vineyards would be the construction of protective roofs stored away from the Rebber prohibit, since the critical late frost situation can often be recognized only in such a short time that the structure can be done only in time, not to mention the organization of the required staff and the cost of Auf - and the mining.

Abstract

La présente invention concerne un toit protecteur (10, 26, 27, 70), rétractable et pneumatique, destinée à des vignobles (1), lequel comprend : des chambres structurelles (31 à 34, 71 à 74), pouvant être réglées en volume par déformation, remplies de gaz et à nouveau vidées ; un moyen pour générer de la pression dans les chambres structurelles (31 à 34) et un agencement de rétraction dudit toit protecteur (10, 26, 27, 70), le moyen pour générer de la pression étant conçu pour maintenir, au moins dans l'état de remplissage partiel des chambres structurelles (31 à 34), une pression de fonctionnement prédéterminée, dépassant la pression ambiante et l'agencement de rétraction du toit protecteur (10, 26, 27, 70) étant conçu pour réduire le volume des chambres structurelles (31 à 34) dans le sens contraire au sens de la pression de fonctionnement maintenue. Au moyen du toit protecteur selon invention, des dommages causés par le gel tardif peuvent être évités, ainsi que des dommages causés par la grêle.
