FR2843005A1 - Outdoor screen for wind-break or sight-screen comprises woven or perforated plastic panel with reinforcing bar along top and/or bottom edge - Google Patents

Abstract

The screen consists of plastic panel (1) with woven, perforated or cellular structure and hollow reinforcing bar(s) (I)(2) along its top and/or bottom edge. (I) are made from rigid or semi-rigid plastic, and each has flat base (3) and two converging sides with a gap between their edges to receive the screen panel. One of the sides has a rounded edge to facilitate insertion of panel. (I) are made in lengths shorter than height of panel, joined together end-to-end by inserts.

Description

The present invention relates to an effect concealment structure

windbreak

  and screening, in particular for balconies, terraces, gardens and growing areas.

  Screens are commonly used for this purpose, called canisses, made up of open or closed, elongated profiled elements, of curved section, joined by lines of links extending transversely with respect to the longitudinal direction of the profiled elements. The profiled elements can be of a natural material, in particular of

  bamboo, or a relatively rigid plastic, especially PVC.

  Screens are also commonly used, consisting of a plastic sheet provided with perforations or a sheet with a reticular structure with square meshes or

in rhombus.

  The screens are generally fixed at intervals by means of attachment to

  supporting elements, such as stakes or uprights.

  Due to their exposure to external atmospheric phenomena, especially wind, rain and sun, these screens do not retain their dimensional stability over time, and more or less significant deformations are noted.

  sometimes leading to tears.

  The present invention proposes to provide a concealment structure which, by simple and economical means, avoids or, at the very least, significantly delays the

  risk of deformation over time.

  The concealment structure according to the invention comprises a screen and at least one profiled stiffening rod, advantageously made of rigid or semi-rigid plastic material such as PVC, capable of being put in place by sliding on the edge.

  upper and / or lower edge of the screen.

  Preferably, the or each of the rods has a flat base wall from which extend two converging branches defining, between their ends

  free, a slot through which the rod can be engaged on the screen.

  The rod (s) of the concealment structure according to the invention which, as is easily understood, provide a stiffening function at the edges of the screen, advantageously have at least one of their longitudinal ends a cut, in particular in the shape of a rounded bevel, at the end of one of the converging branches so as to facilitate the positioning of the rod by its

  end on the corresponding edge of the screen.

  The length of the stiffening rods can be arbitrary and several rods can be placed successively on the same edge of the screen. The

  rods can also be cut to the required length.

  In addition, the stiffening strips according to the invention make it possible, if necessary, to connect two screen sections by overlapping the respective ends of the

two sections.

  Blackout screens, in particular plastic, are generally packaged in rolls, usually covered with a transparent film of shrinkable plastic, a product identification sheet being most often interposed

  between the outer periphery of the roll and the plastic film.

  The height of the roll is, in this type of packaging, the height of the screen. It is then advantageous for the length of the stiffening rod (s) to be

  less than or equal to the height of the screen.

  It is thus possible to place rods in the center of the roller or

  its periphery without significantly modifying the appearance of the packaging.

  Of course, the concealment structures according to the invention can be presented for sale, and if necessary, conditioned with stiffening rods placed on the upper and lower edges of the screen, thus forming panels.

practically self-supporting.

  The screens of the structure according to the invention can be of all types traditionally used for the concealment of balconies, terraces, gardens and growing areas and advantageously plastic canisses, consisting of profiled elements of open convex section or of closed biconvex section, joined by bonds fixed by gluing and extending transversely with respect to the longitudinal direction of

profiled elements.

  The screens can also consist of all types of plastic tablecloths traditionally used for this type of application, such as

  perforated or reticular structure tablecloths.

  In order to better understand the invention we will now describe examples in no way limiting with reference to the accompanying drawing in which: - Figure 1 is a schematic perspective view, partially broken away, of a concealment structure according a first embodiment of the invention, - Figure 2 is an enlarged view, also cut away, of a stiffening rod of the structure of Figure 1, and - Figures 3, 4 and 5 are schematic fragmentary views illustrating three other embodiments of concealment structures according to the invention. The concealment structure according to the invention illustrated in FIG. 1 essentially consists of a plastic screen 1 and two stiffening rods 2

  placed along the top and bottom edges of the screen 1.

  The screen 1 illustrated in FIG. 1 is a canisse made up of hollow elongated profiled elements of biconvex section, that is to say flattened oval, joined by lines of links fixed by gluing and extending transversely relative to longitudinal direction

profiled elements.

  Such lines of links are visible in Figure 1.

  Screens of this type are sold in different heights, lengths and

  colors by the applicant company.

  In the exemplary implementation illustrated, the structure according to the invention comprises two stiffening rods in plastic material such as PVC, placed

  place on the upper and lower edges of the screen 1.

  As best seen in Figure 2, each of the rods 2 has a substantially triangular section with a flat base wall 3 from which extend branches 4 converging towards each other, the free ends of the branches

  4 defining between them a slot 5.

  Due to a certain elasticity of the branches 4, these can deviate somewhat when the rod is placed on a screen whose thickness is

  slightly greater than the width of the slot 5.

  The positioning of a rod 2 on an edge of the screen 1 is carried out, as shown schematically for example in FIG. 5, by engaging a rod 2 on an edge of the screen by sliding from one end of the screen to engage the edge

  screen correspondent in the interior volume of the stiffening rod 2.

  This installation can be facilitated by providing the rod 2 at one of its two ends with a cam profile favoring the positioning of the rod 2 on

  screen 1 during its installation.

  As can be seen in FIG. 2, it may be a rounded bevel 6 produced at

  the end of one of the branches 4 of the rod 2.

  According to the invention, it is possible to use any screen, in particular plastic, traditionally used as a windbreak and screen, to make the screen, and in particular the screens illustrated in FIGS. 3, 4 and 5, namely in the figure 3 a perforated sheet 1a, in FIG. 4 a sheet with a reticular structure 1b and in FIG. 5 a canisse

  Ic made up of open profiles of curved section.

  Such screens are also marketed by the applicant company.

  Although the invention has been described in connection with particular embodiments, it is obvious that it is in no way limited thereto and that it can be brought to it in different variants and modifications without departing from its scope or of his mind.
