Definitions

• the present invention relates to a finishing border for the edge of open stair treads, comprising angled elements, the branches of which are intended to be disposed respectively on the edge of the steps parallel to the horizontal and vertical faces thereof.
• this finishing border for stair treads of known type consists of a succession of angled elements of straight cross section in the shape of an L which are arranged end -to-end and which are applied against each other.
• Document GB 2 192 212 relates to an edge of steps which is adjustable and which, consequently, does not require any adjustment, either in length or in angle of the assembled elements.
• the device comprises a first square element which is arranged on the projecting angle of a step and a second square element which is arranged in the inside angle of the step, these two elements being joined by a rectilinear element.
• this step edge system does not lend itself to automatic and easy positioning of the elements, and in particular to a so-called "blank" positioning which consists, before any fixing, of placing the edge elements on all of the steps constituting a staircase; in fact, in such a device, a simple positioning of the elements does not immobilize them relative to one another.
• the document DE 27 11 491 also describes a border for edges of stair treads which is made up of sections of slide cut to length and fixed to the edges of the step and these edges of steps have wings which are mounted to slide inside. of the slide section.

• the present invention aims to remedy the aforementioned drawbacks by proposing a finishing border for stairs which is both easy and quick to implement and which, for its installation, does not require any cutting or adjustment of the border whatever it is.
• the present invention thus relates to a finishing border for singing open stair treads as mentioned in the preamble, which is characterized in that the angled elements have substantially flat branches and are intended to match the salient angles of the step covering only the edge of the step, a junction element ensuring continuity between two adjacent square elements.
• the joining element is also in the form of a square and comprises means for holding with the two adjacent branches of two consecutive square elements.
• each of the branches of the angled junction element forms a sheath capable of admitting, by sliding, each of the branches of the angled elements.
• each angled element comprises means making it possible to ensure the positioning of one of its branches relative to the horizontal face of the step and of its other branch relative to the vertical face of the step.
• the positioning means consist of tabs perpendicular to the plane of the square element and which are parallel to the main direction of each of the branches.
• the junction element in the form of a square has branches of short length relative to the branches of the square elements.

• FIG. 1 a staircase 1 whose steps 3 which provided with a finishing border according to the invention.
• the finishing border is made up of square elements 5 consisting of a flat iron with branches 5a and 5b at 90 ° comprising, as shown in FIG. 2, fixing lugs 7a and 7b which are arranged, d on the one hand, perpendicular to the square element 5 and, on the other hand, respectively along the longitudinal axis xx 'and yy' of each of the branches 5a and 5b of the element 5.
• the external surfaces of the steps 3 namely their horizontal and vertical surfaces, have been represented by a dashed line.
• the finishing border according to the invention also comprises a joining element 9, which is square in the present embodiment, and whose branches 9a are of dimensions smaller than the branches of the square element 5.
• the connecting element 9 comprises side portions 11 which are folded parallel to the main face of the element 9 so as to constitute a sheath in which the branches 5a and 5b of the square element 5 can slide.
• the user can start by setting up the lower angled element 5, which bears on the upper face and on the edge of the step 3, by its respective legs 7a and 7b which form stops, and which are then fixed in step 3 at 1 'with any suitable sealing means.
• the user then has, on the horizontal branch 5a of the square element 5, a junction element 9, then he introduces into the vertical branch 9a of the latter the vertical branch 5b of another square element 5 which, in turn, is supported on the next step 4 by its legs 7a and 7b. As before, these are then fixed on step 3.
• the user thus proceeds from step to step until he reaches the upper part of the staircase 1.
• Such a fixing edge has on the devices of the prior art the advantage of not requiring lengthening of each of the branches 5a and 5b of the square element 5, since the differences in length are compensated by the length of the branches 9a of the junction element 9. It also has the advantage of tolerating the few squaring defects which usually exist on industrial markets, insofar as a slight clearance is provided between the sheath constituted by the branches 9a of the junction element 9 and the branches 5a and 5b of the square element 5.
• the fixing of the square elements 5 on the steps 3 can be carried out by any other means than a sealing of the legs 7a and 7b.
• the latter can thus be used to ensure fixing by gluing or by fusion of a hot-melt product.
• joining elements which comprise, as shown in FIG. 4, fixing lugs 15a and 15b which are provided in the corner of this element and which are intended to take place in a hollow formed between the horizontal and vertical faces of a step 3.
• junction elements 9 ' which are made up of plates, which may be of various shapes, and which are fixed either on each of the ends of the branches 5a and 5b of the square elements 5, or directly in the body of the staircase 1 by gluing, sealing, hot-melt resin, etc.
• the finishing border according to the invention comprises joining elements 9 ′ which are straight and in the form of sleeves and angle elements 5 ′ which consist of a flat iron.
• the straight junction elements 9 ′ may consist, as shown in FIG. 5, of a piece of sheet metal which is folded so as to constitute a sleeve and a fixing lug 7 ′ which extends over the entire length of the 'element.

• the user then introduces a branch 5 ′ with a square element 5 ′ into the junction element 9 ′ fixed on the horizontal face of the first step, and the other branch 5 ′ a of this element 5 'in another junction element 9' which it positions relative to this branch by sliding and then fixes on the vertical face of the second step.
• the user thus proceeds from step to step until the finishing edge reaches the upper part of the staircase 1.
• the step 3 of a staircase is covered with a carpet 4 and the angle of each of the steps 3 is provided with a square stair nose 6.
