Definitions

  • the object of the present invention is a canopy assembly for a sunshade.
  • the present invention also refers to a sunshade comprising said canopy assembly.
  • a canopy assembly according to the present invention comprises a tensioning device for the canopy sheet.
  • Roll-up shading sail installations to provide an extensible and temporary canopy to protect or shield the users of an outdoor area from the weather are generally known.
  • Such installations of a known type generally comprise a roller free to rotate, around which at least one sail or awning is wound, supporting uprights anchored to the ground to keep the roller suspended off the ground, the covering element, i.e. the same sail or awning, and a circuit for the unfurling and winding of the sail or awning.
  • This unfurling and winding circuit of the sail usually provides for a cord stretched between the sail and a rotating spool, sometimes motorized, so that the rotating spool advantageously causes the cord to roll up, pulling the sail so as to unwind it progressively from the roller and unfurl it.
  • the sail is wound around the roller by rotating the roller in the opposite direction, which consequently progressively reels off the cord from the spool.
  • a loose sail or awning is subject to significant instability when hit by air currents and at the same time prevents adequate drainage of liquids, such as rainwater, which accumulate in pockets.
  • a loose sail or awning hit by air currents overstrains the anchors of the uprights of the installation on the ground. These effects are undesirable as they compromise the safety of the installation as well as the integrity of the sail itself.
  • document US-6012505 shows a device adapted to tension the sail canopy of a sail sunshade.
  • This device comprises a system of coil springs arranged in a cross shape joined to portions of the cord stretched between the spool and one of the edges of the sail canopy.
  • the cross-shaped spring is placed in such a position as to overhang the space usable by the sail canopy in any configuration of use of the sunshade, in other words, these cross-shaped springs remain in the same position both when the sail canopy is unfurled and when the sail canopy is wrapped around the winder roller.
  • this system of metal springs arranged in a cross may undergo early rust as a result of precipitation with the risk of staining with rust, by dripping, the sail canopy when it is unfurled, as well as the furniture or users in the underlying area on the ground when the canopy is closed or rolled up.
  • the size of such springs calculated in the longitudinal direction, but also in the transverse direction, is necessarily limited to a fraction of the size of the sail for reasons of size and weight, as well as aesthetics, alternatively requiring the use of very hard, and thus expensive, springs to obtain a strong tension or being satisfied with a lesser elastic action.
  • these torsion springs require rolling awnings or sails to be made of modest extension while being totally unsuitable for keeping large sails or awnings taut. Moreover, such torsion springs are inherently unsuitable for keeping two sails extending in opposite directions taut by a single winder.
  • the need is therefore strongly felt to provide a device to keep the sail or awning taut in every step of use of the sunshade, while giving the sunshade an aesthetically pleasing appearance, without thereby requiring frequent maintenance of the sunshade or the parts thereof.
  • One of the aims of the present invention is to remedy the drawbacks of the prior art reported so far and to provide a solution to the needs mentioned with reference to the state of the art.

  • said canopy assembly comprises a boom comprising said winder roller.
  • Said winder roller 5 and said at least one sheet tensioning device cooperate to alternately roll up and/or unfurl at least partially said canopy sheet 4.
