Description

The present invention relates to a self-supporting railing comprising a shoe, an amount supported by the shoe and a deporting arm received inside the shoe and designed to be equipped with at least one ballast element.

The term guardrail means a set of elements forming a protective barrier. A self-standing railing is a guardrail that is not permanently attached to a construction structure but is ballasted on the construction work to prevent any tipping. This type of self-supporting railing is very advantageous especially for a quick and inexpensive assembly / disassembly and to ensure the tightness of the construction work by avoiding damage to the support surface of the guardrail.

Most known self-standing guardrails conventionally comprise a plurality of uprights which support substantially horizontal rails, each upright being supported at the bottom by a hoof resting on the construction structure and receiving internally an offset arm equipped with least free end of at least one ballast element.

Such self-standing guardrails are known in particular documents FR 2 960 249 , FR 2 939 461 , FR 2 919 642 , FR 2,980,226 or EP 2 525 015 , where the shoe is made in the form of a one-piece piece of complex and expensive design, and impractical to allow an adjustable inclination of the amount.

It is also known from the document EP 0 288 100 to use a self-supporting railing comprising an upright and an offset arm designed to be equipped with at least one weighting element, where the amount is, on the one hand, articulated on the offset arm by means of a hinge and is, on the other hand, attached to the offset arm by means of rods fixed at mid-height of the amount and fixed at mid-length of the offset arm.

The state of the art can also be illustrated by teaching the document FR 2 934 624 which discloses a self-supporting railing comprising an upright and an offset arm designed to be equipped with at least one ballast element, and a one-piece shoe supporting the upright and receiving the offset arm.

The object of the present invention is to propose a self-supporting railing having a simple and inexpensive hoof design, which is advantageously adapted to allow adjustment of the inclination of the upright and / or to receive a plinth.

For this purpose, it proposes a self-supporting railing comprising a shoe, an amount supported by the shoe and at least one offset arm received inside the shoe and designed to be equipped with at least one weighting element, said railing being characterized in that the shoe comprises two independent flanges, facing one another and assembled by at least one lower clamping system through the flanges and the offset arm, and by at least one locking system. upper clamping through the flanges and the upright, wherein the upright and the offset arm are clamped between the two flanges by means of the lower and upper clamping systems, and wherein the railing comprises a pivot axis passing through the flanges and the amount to allow a pivoting of the amount on the shoe around said pivot axis, and the upper clamping system comprises a threaded rod through the flanges and the amount and cooperating with an echo u clamping, where the flanges each have several upper holes provided for the passage of the threaded rod to allow a locking of the amount of several inclinations.

Thus, it is sufficient to place the flanges on either side of the upright and the offset arm, so that the amount and this offset arm are interposed between these flanges, and to tighten the lower and upper clamping systems to maintain fix the amount and the arm of offset between the flanges. It is understood, within the meaning of the present application, that the flanges are independent in the sense that the flanges do not form the two parts of the same single piece and will be associated (or assembled) at least when the lower clamping systems and higher will be put in place.

In addition, thanks to the invention, the amount pivots about the pivot axis which is carried by the flanges, and the threaded rod is positionable on different upper holes to allow adjustment of the inclination of the amount.

It should be noted that, in the context of the invention, the amount is not articulated (or pivoting) directly on the offset arm, in the sense that the amount is hinged (or pivoting) between the flanges of the shoe.

According to one characteristic, each flange comprises, among the upper holes, a main upper hole in the shape of a circular arc centered on the pivot axis and having an upper end and a lower end, and the upright has a main through hole alignable with each main upper hole so that the threaded rod is adapted to pass through the main upper holes of the flanges and the main hole of the upright, to allow a locking of the amount of an adjustable tilt according to the position of the threaded rod between the upper and lower ends of the upper main holes.

Such principal upper holes thus make it possible to guide, in a continuous or non-discrete manner, the threaded rod between the upper and lower ends of the main upper holes, and thus to continuously adjust the inclination of the upright between two extreme inclinations defined by the high and low ends of the main top holes.

According to another characteristic, the main upper holes extend over substantially 90 degrees with shaped high ends for blocking the upright at a substantially vertical inclination and with low ends shaped for locking the upright at a substantially horizontal inclination.

In a particular embodiment, each flange comprises, among the upper holes, at least two secondary upper holes angularly offset about the pivot axis, and the upright has a through secondary orifice that can be aligned on said secondary upper holes so that the Threaded rod is able to pass through said secondary upper holes of the flanges and the secondary orifice of the upright, to allow a locking of the upright at several fixed inclinations depending on whether the threaded rod passes through one or other of the secondary upper holes.

Thus, these secondary upper holes define fixed (or discrete) inclinations of the upright, with the possibility of changing inclination by changing secondary upper holes for the passage of the threaded rod.

Advantageously, the at least two secondary upper holes comprise first secondary upper holes for locking the upright at a vertical inclination, and second secondary upper holes for locking the upright at a non-vertical and non-horizontal inclination.

In an advantageous embodiment, each flange has a main wall in which are formed the upper holes and provided with a vertical edge on which is provided a vertical flange folded at right angles to the main wall and provided with at least one light, where the vertical wings of the flanges are coplanar and the guardrail further comprises a skirting board fixed on said vertical flanges by means of screws passing through their respective slots . Thus, the shoe is shaped to receive a plinth.

According to a possibility of the invention, the pivot axis is positioned relative to the vertical wings so that the amount is pivotable without coming into contact with the baseboard.

According to another possibility of the invention, the lights are oblong in a vertical direction to allow a vertical adjustment of the position of the plinth on the shoe.

According to another characteristic of the invention, the guardrail further comprises a pad fixed on the underside of the shoe.

Advantageously, each flange has a main wall in which are formed the upper holes and provided with a horizontal edge on which is provided a horizontal flange folded at right angles to the main wall, and the pad is fixed by clipping on the wings horizontal flanges.

The present invention also relates to the characteristic that each flange is composed of a sheet metal plate.
