DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a device for the securement of wall coverings and the like, with invisible mounting, particularly sheets and cloths, natural or synthetic.
BACKGROUND OF THE INVENTION
In this field, the applicant has proposed in its French patent application No. 9104572, filed Apr. 15, 1991, a specific profile comprising a flexible strip for mounting the cloth, a tapered edge to receive the border of the cloth, a double-faced adhesive strip for straight line adjustment of the cloth and a gripper adapted for clamping the padding by its edge.
But such a profile cannot be used in particular cases such as those relating to corners of doors and windows, the required angles and all the cases in which the narrowness of the panels renders difficult the execution because of too great width of the profile. On the other hand, the shape of the strip proposed in this parallel lipped profile for the tapered edge does not permit in all cases sufficient retention of the cloth between itself and the confronting portion.
SUMMARY OF THE INVENTION
The device according to the present invention particularly overcomes these drawbacks.
According to a first characteristic, the invention has for its object a profile of the type comprising on the one hand a hollowed out edge, for example tapered and on the other hand a flexible strip running parallel to the axis of the profile and prolonging the end edge defined by the acute angle of the bevel or of the recess at the level of the upper surface and in which this flexible strip comprises two spaced lips lying in a same plane perpendicular to the bearing surface for the profile and parallel to the edges of said profile.
According to a preferred embodiment, the two lips of the strip are disposed in diverging relation, with a first lip having a rounded bevelled edge in a direction opposite to the bevelled edge connecting the strip to the surface for bearing and mounting of the profile; the second lip is perpendicular to this edge such that the conjoint effect of the two lips of the strip guarantees a complete securement of the cloth against an adjacent wall or another profile in the case of angled fittings.
According to a first modification adapted for the mounting of sheets and cloths except doubled sheets, padding, linings, etc., this profile is simply constituted of a profile of the lath type of small width called "Jonc", in the term of art, of a width of the order of 15 mm including the width of the strip. This profile whose width is reduced to a fraction relative to a gripping profile, permits covering narrow surfaces, down to 30 mm width, using two profiles whose edges opposite the strip are disposed side by side. In the case of and according to another characteristic, all the upper surface of the profile of small width on which come to rest the stretched cloth, is counterglued with an adhesive double-faced strip. According to another modification in the case in which the profile is adapted to receive a padding or lining by means of a longitudinal recess opening on the upper surface and closed by a gripper extending over all the width: said gripper is provided on the lower portion of its end with a small tongue directed downwardly and inclined in the direction of the base of the gripper to ensure a retention of the padding with a non-return means in the fashion of a harpoon.
BRIEF DESCRIPTION OF THE DRAWINGS
The profile comprising the invention is of a white synthetic material, for example PVC. Its characteristics and advantages will become apparent from the description which follows with reference to the accompanying drawings: FIG. 1 is a perspective view of the profile forming the device according to the invention, FIG. 2 shows the arrangement of the profiles in a corner of a wall behind a door seen from the front. FIG. 3 is an enlarged cross-sectional view of this arrangement. FIG. 4 shows a perspective view of the profile with the gripper.
DETAILED DESCRIPTION OF THE INVENTION
This device is constituted by a thin white profile
