<p>The anti-hail shelter comprises a flexible cover (7) supported by a frame (8) comprising purlins (9-12) connected transversely by regularly spaced ties. Each covering is located between each pair of purlins and interlaced between the different ties. The ties are alternately set back in height along the purlins to form two sets of parallel upper and lower ties. The cover passes on top of each upper tie and under each lower tie to define, in a longitudinal section, a broken line constituted of alternate re-entrant and projecting corners. Each cover is tensioned on the support frame by a tensioner (18).</p> |
