FR2842244A1 - Sun shade awning for garden has hot air vent gaps formed at spaced points in awning fabric mounted on upper and lower reels - Google Patents

Abstract

The sun shade awning has lateral, horizontal or vertical gaps. It can have laterally spaced horizontal and vertical strips (1,2) assembled in a common plane. The shade can have two layers with reels, with the lower reel being movable to allow the lower runs to be placed against the upper to form a closed surface.

Description

Airy protection device against solar radiation

  current devices for protection against solar radiation, in particular tarpaulins and parasols, have the drawback of causing the air located on the face in the shade to heat up, leading to a rise in temperature in

protected space.

  The device according to the invention significantly improves the comfort of users. Consisting of several elements, flexible or rigid, arranged on one or more levels, spaced laterally, parallel or crossed, it provides a cooler shade, because it allows the superheated air to escape and it reduces the heating of the closest to users

  as well as the solar radiation passing through it.

  The accompanying drawings show the three variants of the device according to the invention: The variant with crossed elements (references 1 and 3) is illustrated seen from the side on a parasol panel in FIGS. 1 and 2, the

  section A-A shows the vertical arrangement of the elements.

  The variant with superimposed parallel elements is presented in FIGS. 3 (example of sliding mounting on parallel bars) and 4 (example of mounting on reels). In Figure 5 is the tensioning device of the lower reel, Figure 6 gives a representation of the fixing of the lower ends of the strips on the movable bar

  (item 5 in Figure 4) of the cover, here in another version.

  The variant with parallel elements on the same plane is shown from the side on a parasol panel in FIG. 7. FIGS. 8 and 9 show the operation of the tensioning of the upper edge of an element. A cord (6) fixed at (7) on the upper edge of the element slides in a loop (8) to modify the tension of the upper edge of the element which, stretched, forms a fold (mark 10, figure 9) against the whale. The reinforcement at the base of each horizontal element is

  represented by the reference 9 in FIG. 8.

  -2 The device according to the invention is available in three variants with elements crossed on one or two planes, with parallel elements

  superimposed and with parallel elements on the same plane.

  The first variant of the device according to the invention, intended to be used in particular on parasols, beach, garden or site shelters as well as on blinds, is illustrated in FIG. 1. This variant consists of elements, in particular in fabric, spaced laterally, arranged horizontally (1) and vertically (3). On a parasol, their ends can be assembled on a strip, in particular in fabric, fixed to the ends of each whale, ensuring their positioning and the tension of the strips. In the double thickness version, see FIG. 2, the vertical elements can be assembled on a triangle constituted in particular by a rope stretched between the ends of the whales by elastic rings (4) by leaving a space between the horizontal elements and the vertical elements . The significant overlap of the strips provides reinforced protection against the sun's rays, their horizontal (2) spacing (the strips are not contiguous) and vertical allows air circulation between the layers, ensuring permanent ventilation which avoids the heating of their underside as well as the air which is under the device according to the invention. This variant is also possible without vertical space between the strips, which are then sewn together. A version of this variant of the device according to the invention is devoid of vertical strips, allowing more economical manufacture, at the cost of one

  less protection against solar radiation.

  The second variant of the device according to the invention, intended in particular for blinds as well as for tarpaulins, in particular mounted on reels or sliding on metal rods, is illustrated in FIGS. 3 and 4. The parallel and non-contiguous strips also provide significant overlap. . The air circulation is ensured by the vertical space between the two planes as well as by the lateral spacing of the strips. The version on reels of this variant can be designed so as to allow the adjustment of the vertical space between the planes of -3

  strips, in particular to ensure the tightness of the structure.

  In this configuration, a reel is mobile, allowing the strips to be placed on the same plane. A spring or a suspension device, the counterweight of which consists of a container containing water or sand, see FIG. 5, makes it possible to obtain an adequate tension of the strips which are not mounted on the reel driven. To prevent rainwater from leaking between the strips, these can be fixed on the movable bar modified according to FIG. 6, which gives their lower end a shape

gutter.

  The third variant of the device according to the invention, intended in particular to be used on parasols, on garden trellises or on patio covers / awnings, is illustrated in FIG. 7. Apart from the ridge strip, the strips are stretched on their lower edge and free on their upper edge. The lateral edges of the strips are integral with the fixed parts of the structure. The upper edge of each strip is longer than the distance between its fixing points in order to hang, thus creating an opening intended to let air pass. Cords, see figure 8, are fixed on the upper edge of each strip, at a distance allowing to stretch the strip, figure 9, and thus to form a flat surface whose free stretched edge is positioned under the fixed edge of the upper strip to ensure watertightness. The cords are guided by passers-by to a fixed element of the structure, in particular the mast of an umbrella or a pillar of a garden arbor, in order to allow the strips to be maneuvered from the ground. The cords on each side of the structure are grouped, allowing the simultaneous opening of all the strips of the face to be modified in a single gesture, in order to protect themselves from the sun's rays according to its orientation during the day. The forces applied to the lower edge of the strips are supported by an element having mechanical strength

  sufficient, especially a wire rope.

  In the embodiment according to FIG. 1, the strips, not contiguous in order to allow the evacuation of hot air, are fixed in the horizontal direction on the upper face and, in the vertical direction, on the lower face of the whales -4 folding umbrella-type structure. The tension of the strips along the whales is ensured by their mounting on a strip of fabric fixed at the two ends of each whale. The vertical strips are assembled on a triangle formed by a rope stretched between the ends of the whales by elastic rings, leaving a space between the horizontal strips and the vertical strips. The spacing of the strips of each side is ensured

  especially by the thickness of the whales.

  The device according to the invention can be mounted on structures of the parasol, spade type for a terrace (awning, awning), awning, garden trellis or beach or worksite shelter stretched between masts or on one or more flexible hoops with elements nestable type of those used in camping tents. -5
