Definitions

• the present invention relates to the field of false walls such as false ceilings and false walls and in particular those constituted by a flexible sheet not perfectly stretched hung along its edges to a support fixed to the walls or ceiling of a piece of a building.
• Stretched false ceilings which comprise on the one hand a frame fixed to the walls or to the ceiling of a room, this frame being formed by an outer rail itself consisting of abutting profiles, and on the other hand, a flexible ply stretched inside this frame, this flexible ply being constituted by a sheet of plastic or a fabric.
• the flexible sheet is held taut because of the attachment, on the rail, of a border integral with the web forming a harpoon, this border having in cross section the shape of a hook which grips on a shoulder of the smooth.
• the object of the present invention is therefore to present a new system for fixing false walls consisting of a flexible sheet not perfectly stretched and hung by its borders to a frame fixed to the walls or the ceiling of a part of a building, said frame being constituted by smooth having a shoulder on which the edge bears, said edge or harpoon having a hook-shaped section and having a wing by which said harpoon is connected to the web and a bead.
• the system according to the invention is remarkable in that the integral edge of the web, or harpoon, is made of a semi-flexible material and has a degree of flexibility such that the two branches deviate at least from 45 ° from each other after said edge has been inserted into the rail, so that the portion of the inner face of the bead, that is to say the face facing the wing, which is located towards the free end of said bead is in contact with the shoulder and thus ensures a frictional hold of the harpoon in the smooth.
• FIG. 1 is a partial vertical sectional view of a false ceiling consisting of a stretched web, and having a rail attached to the upper part of a wall of a room according to the known prior art;
• FIG. 2 is a partial vertical sectional view, at the same scale and at the same angle of view that Figure 1, a false ceiling consists of a not perfectly stretched sheet having a smooth identical to that shown in Figure 1 and an alternative embodiment of the fastening system according to the invention.
• Figure 1 shows the end portion of a false ceiling according to the prior art, which is constituted by a flexible sheet 1 stretched horizontally below the ceiling 2 of a room. This sheet 1 is fixed along its edges to a support consisting of a horizontal rail 3, itself attached to the upper part of a wall 4 of the part by appropriate means, not shown, such as screws.
• This smooth 3 comprises an outer vertical wing 5 which extends parallel to the wall 4 and in the immediate vicinity thereof.
• This outer vertical wing 5 is issued, at about halfway up, an upper horizontal web 6 extending over a small distance, for example of the order of 7 mm, towards the interior of the room.
• This core 6 is extended, at its end, by an internal vertical wing 7 extending downward a little lower than the outer wing 5 near the wall 4, that is to say that the inner wing 7 is a little higher than the outer wing 5 of said smooth.
• This outer flange 5 has, at its lower end, a shoulder 8 extending horizontally towards the interior of the part, over a short distance which is for example 3 mm.
• This shoulder to the square 8 advantageously has a rounded end.
• the lower part of the outer vertical wing 5, the upper horizontal web 6 and the vertical wing 7 constitute a recess 9 open towards the bottom and in which is engaged a harpoon 10 forming the edge of the stretched flexible sheet 1.
• This harpoon 10 has in cross section a form of hook extending towards the wall 4 and open downwards. he comprises an inner limb 10a 1 , or wing, by which it is connected to the ply 1, and an outer branch 10b in the form of a bead at the rounded end, which is curved downwards.
• the harpoon 10 is supported, when the sheet 1 is stretched, on the shoulder 8 by the lower end of its outer branch 10b which extends downwards.
• This harpoon 10 is simply supported on the lower horizontal shoulder 8 by its bead 10b and therefore, its setting in hooking position is greatly facilitated. Indeed, during the assembly of the stretched fabric, it suffices to push the harpoon 10 upwards in the recess 9, by means of a suitable tool, such as a spatula engaged in this harpoon 10, to make it pass between the shoulder 8 and the vertical flange 7 and bring it above the shoulder 8. When the harpoon 10 is released, it then comes to rest on the shoulder 8 ensuring a perfect maintenance of the stretched web 1, thanks to the spring effect between the two branches of the harpoon provided by the material in which it is manufactured and the traction exerted on the inner branch 10a by the web 1.
• the effect mentioned spring consists of a rimpedement of the two branches. The angle formed between the two branches of the harpoon in position is less than 15 °.
• the dimensions of the represented variant of the harpoon 10 'according to the invention are, concerning the length of its wing 10' a, or internal branch, and its bead 10'b, or external branch, less than those of the harpoon 10 conventionally used and shown in FIG. 1: FIGS. 1 and 2 being at the same scale, the branch external of the represented variant of the harpoon 10 'according to the invention, also called mini-harpoon, has almost the same length as the inner branch of the harpoon 10 of the prior art.
• the dimensions of the harpoon 10 ' are not limiting of the invention and that in another alternative embodiment of the fastening system according to the invention, not shown, the harpoon 10' may have dimensions similar to that of the conventional harpoon 10.
• the border, or harpoon 10 ' is made of a semi-flexible material and has a degree of flexibility such that the two branches 10' a and 10 ' b deviate at least 45 ° from each other after said edge has been inserted into the rail 3, so that the portion of the inner face of the bead 10'b, that is to say the face facing the wing 10 'a, which is located towards the free end of said bead is in contact with the shoulder 8 and thus provides a frictional hold of the harpoon 10' in the smooth 3.
• the harpoon 10 'object of the present invention is advantageously made of a plastic material extruded semi-flexible, similar to that of the spear 10 constituting the prior art but providing a higher degree of flexibility so that the branches can deviate from one another.
• the weight exerted by the flexible web 1 on the harpoon will move the two branches thereof.
• the angle of separation of the two branches is at least 45 °. Preferably, it will be between 70 ° and 130 °, preferably close to 90 °. Thanks to this separation of the branches, the portion of the inner face of the bead 10'b located towards its free end comes into contact with the surface of the shoulder 8. The friction force exerted is sufficient to allow the holding in place of the harpoon 10 'without the possibility of improper release of it.
• the lower end of the bead 10 'of the harpoon 10' may be advantageously bevelled so as to have a flat section.
• the end of the bead 10 'b being beveled, it has two surfaces so blunt one is in contact with the shoulder 8. It is understood that the contacting surfaces being flat, the maintenance provided by the forces of friction will only be better.
