FR2840439A1 - Projection device with multiple surfaces onto which moving and or advertising images can be projected, with said surfaces having the form of vane type flags that are moved simultaneously in a natural or artificial wind - Google Patents

Abstract

Device onto which images are to be projected, e.g. for advertising purposes, comprises multiple vane type flags, which serve as projection surfaces and are visible from all angles. The flags (3) are mounted over vertical axes (2), which are in turn supported by support chains (1), such that a projection surface (1, 3) is formed.

Description

the information of enforcement personnel or third parties.

  The present invention relates to a device which makes it possible to observe projections on a screen swiveling through 360, composed of multiple weather vane flags aligned under a supporting system, which, under the action of the wind, are positioned

simultaneously facing the spectators.

  The projections, video, slide, or light are traditionally reflected on a solid, vertical support, orient and freeze once and for all at

time of installation.

  As a general rule, the projection screens are placed at an angle and a height regulated for the visual comfort of the spectators. This implies, closing the horizon by the projection support, and therefore reducing the visual field, as well as the usable space behind these same screens. In addition, when the technical means ask to put a structure on the ground (anchor points and barriers), this forces to increase the surfaces and volumes and to decrease the reception capacities (public or services) as well as the possibilities of evacuation linked to the exits of

1 5 rescue.

  Also, in cases where spectators find themselves conditioned in the configuration of an arena, finding themselves face to face around a central animation, the screens or projection supports are generally multiplied and placed at

  different places, depending on the distance and the orientation of these same spectators.

  The device according to the invention makes it possible to remedy these drawbacks. I1 indeed has according to a first characteristic, the advantage of proposing a horizontal installation of the projection surface, while retaining a vertical reading. This makes it possible to remove the constraints linked to the deformation of the image, or to the position of the projection apparatus, while preserving a natural readability,

  as well as visibility and cleared access.

  The device according to the invention comprises a second characteristic, relating to the weather vane flags, which, chosen and cut for the best grip at

  wind, storient and rotate 360, thus forming a screen visible from all angles.

  The device according to the invention comprises, a third characteristic concerning the projection surface, which, by its lightness and its flexibility, offers the possibility of being installed in multiple configurations (ceilings, walls, columns

  or other geometries) while keeping a vertical reading.

  The device according to the invention also includes a fourth characteristic relating to the projection surface, the wind resistance of which is almost zero compared to the

deployed surface.

  According to particular embodiments: - The projection surface consists of at least one support sling (1), which supports a set of masts (2) on which wind strings of flags (3) retained

by a stop (4).

  - The support slings (1) can be individual or fixed between two bars.

  - The support slings (1) can be steel cables or fiber cords.

  - 2 - The support slings (1) can be replaced by any other support

  allowing to arrange the mats to form a surface.

  - The wire (5) which allows the adjustment can be made of nylon or other materials and can be

find under the support ltelingue.

  - The stops (6) can be 8tres fixed directly on the support sling. - The stops (6) can be fishing sinkers or other wedges allowing to

  keep the masts in position on the slings.

  - The masts (2) can be P.V.C. tubes classes M1.

  - The stop (4) which is at the base of the mast, preventing the flag from flying, can

  8tre molded in an M1 material, then glued or nested.

  - The flags can be 8l in textile Ml. Or other materials adapting to it.

  - The stiffening tape can be 8g from the twill.

  The photos and drawings of the 3 adjacent sheets illustrate the invention: the photo sheet 1/3 shows, an example of the device of the invention, here called:

the projection surface.

  The drawing on board 2/3 represents a close-up view of the projection surface The drawing on board 3/3 represents the front and sectional views of one of the flags

  which makes up the device of the invention.

  With reference to the photo plate 1/3, and as an indication, the projection surface photographed is composed of 144 flags and represents 36 m2, raised from one side to

  6 meters 60 and on the other side to 4 meters 40.

  With reference to the drawings on board 3/3: on the flag (3) is sewn a filled

  (7) which allows it to be threaded onto the mast (2), and it is held in place using a stop (4).

  The upper part of the mat (2) has two transverse orifices (8) and (9).

  The upper hole (8) allows the passage of the adjustment wire (5) on which wind fixes stops (6) which space the flags evenly and offer a deployment

  convenient. The lower orifice (9) allows the passage of the support gel (1).

According to variants not illustrated:

  - The projection surfaces can be superimposed to improve the rendering.

  - The flags can have other shapes and dimensions.

  - The masts can be fixed on another support.

  - The filled can be reinforced with a stiffening tape.

By way of nonlimiting example:

  - The flag will have dimensions of the order of 45 x 25 x 51.5 cm.

  - The mast tube will have a diameter of 16 mm. and a length of 30 cm.

  - The flags will be in textile class M1.

  - The stiffening ribbon will be in 2 cm twill.

  - The nylon thread will have a diameter of 0.8 mm.

  - The support gel will have a diameter of 2 mm.

  The device according to the invention is particularly intended for projections

  events, for advertising or entertainment purposes.
