FR2476736A1 - Infill lath for existing wire grille fences - has S=shaped plan contour for longitudinal rigidity in torsion - Google Patents

Abstract

The lath can be made of wood, metal or plastics as long as it is thin enough to penetrate the existing mesh of the screen. The finished screen can be used to conceal areas to obtain privacy or can be used as a wind break, and when it is used as the latter, some wind is allowed to penetrate the gaps to lessen the force upon the screen. If the material is plastics it can be made opaque, it can be made in one or several colours and it can be produced by any machine used for extruding plastics material.

Description

The present invention relates to plastic slats, or other, which can be easily inserted through the meshes of certain types of mesh, in order to obtain an opaque screen or not, depending on the material used.

This new screen arrangement to which the patent refers is characterized by the extra-flat slats or rods, coming from extrusion of the plastic material and of studied shape which must ensure these rods lightness and flexibility without neglecting a certain rigidity. of the latte.

The width of the slats is obviously related to the mesh of the mesh to be considered. For meshes of 5 (in centimeters) we will use slats of 3.5 cm. These can be placed vertically or horizontally. We can also cross them or place them at an angle.

The invention has two objectives: utility and decorative. Under this half: aspect, the slats can be of various colors and constitute panels in the tones plain, bicolored or in bayadère. Utility above all since the panels produced according to the invention make it possible to veil balconies in order to isolate themselves from certain vis-à-vis. They also allow to veil terraces and shelter from the wind.

With the so-called "simple twist" gratings, the mechanical manufacture of which is very widespread, the slipping of the slats is done with great simplicity and they slide on their own, automatically guided by the only bending of the wire of each trams of netting.

With regard to screens for horticulture, we will notice clear advantages over conventional hedges because it will be easier to adjust the wind flow rate on the crops by removing slats in order to insert them on the screen, one in two or two slats installed and a vacuum or any other definition which would seem preferable to the user.

The accompanying drawing sheet will allow a better understanding of the invention without however limiting its scope and for this
FIG. 1 represents a front view of a piece of panel according to the invention
Figure 2 is a side view of the same panel which shows the mechanical folding of the wire called "simple twist".

Figure 3 shows a plan view of this panel portion.

As it is presented the patent includes a conventional mesh 1, marketed universally, and slats 2 which can be manufactured in all wood, metal, plastic. But whatever the material, if it is thin it will advantageously receive the shape of an S, in section to give it a longitudinal rigidity.

These slats can be produced by extrusion or drawn from sheets and hot formed by the press and cut at the same time. This version of course uses plastics. For sheet metal, press work is about the same but without reheating. For wood, traditional work will naturally be suitable and the slats can be flat.

Note, however, that the S-shape of the slats will allow air, wind, to flow without obstructing their passage through the panels. It would also be detrimental to all such installations that they offer too strong a hold in the wind. The interest of these screens is especially to break the violence of the wind.

These slats or rods, object of the invention, can be used freely.

They can be stapled on only a portion of the mesh, in the lower or upper part, in the middle, or on any other part
They will also be used on screen to hide from prying eyes the interior of a private property or, as has just been said, to form artificial hedges in order to obtain windbreakers.

These slats will be used very usefully to close the meshes of chicken coop grids or of certain enclosures to receive poultry or game in order to preserve the chicks from risky escapes. The concealment of meshes will then be done on the lower and even buried part of the mesh.

The plastic slats may have various opaque, translucent or transparent qualities.

The use of colors may be sought.

The interest of installing these screens, designed according to the invention, will not escape people who have young children and who live in apartments with balconies or terraces located on upper floors; it is essential for them to take elementary precautions with small children oblivious to the danger they pose to others by playing with objects that may fall on passers-by.

The present invention is moreover not limited to the embodiments described and shown, but encompasses any variant of execution and / or combination of its various elements.

Claims (3)

1.- Thin slat, flexible or not, in any material, able to be placed side by side, with other similar slats through the mesh of a suitable mesh in order to obtain a screen or lattice to isolate looks or to serve as a windbreaker. 2. A slat according to claim 1, characterized by an S-profile providing said slat with sufficient stiffening to stand on itself at least over a certain length. 3.- Latte according to claim 2, characterized by a manufacture employing machines for extruding plastics or presses and shears using plastics or sheet metal
