The shoe 2 comprises two independent flanges 20 to be assembled and to grip the lower part 30 of the upright 3 and the offset arm 4. Each flange 20 is composed of a folded and pierced sheet metal plate.

Each flange 20 has a main wall 21 in which are formed: - one or more lower holes 22 through, on the bottom of the flange 20; - An intermediate hole 23 through substantially at mid-height of the flange 20; a main upper hole 24, on the top of the flange 20, in the shape of a circular arc centered on the intermediate hole 23 and having an upper end 241 and a lower end 242, where the main upper hole 24 extends over 90 degrees so that it has a quarter-circle shape, with the upper end 241 vertically aligned with the intermediate hole 23 and with the lower end 242 horizontally aligned with the intermediate hole 23; a first circular upper secondary hole 25 situated vertically above the upper end 241 of the upper main hole 24; - A second secondary secondary hole 26 circular angularly offset around the intermediate hole 23 relative to the first upper secondary hole 25 at an angle AN of 10 and 30 degrees.

The main wall 21 is provided with a vertical edge 211 on which is provided a vertical flange 27 folded at right angles to the main wall 21 and provided with an oblong slot 270 in a vertical direction Z. The main wall 21 is provided with a horizontal edge 212 on which is provided a horizontal flange 28 folded at right angles to the main wall 21.

The two wings 27, 28 are folded on the same side of the main wall 21, corresponding to the outer side of the flange 20 or the shoe 2 that is to say, in situation, the side opposite the upright 3 and the offset arm 4.

On the shoe 2, in the situation, the flanges 2 are arranged facing one another, with their main walls 21 in parallel, with their holes 22, 23, 24, 25, 26 in alignment, with their vertical wings. 27 coplanar and vertical and with their horizontal wings coplanar and horizontal.

The upright 3 is pivotally mounted on the shoe 2, and more specifically between the flanges 20. As such, the railing 1 comprises a pivot axis 5 passing through the intermediate holes 23 of the flanges 20 and passing through the pivot hole of the amount 3, to allow a pivoting of the upright 3 about this pivot axis 5, thereby adjusting the inclination of the upright 3 relative to the vertical direction Z. For example, the pivot axis 5 comprises two rivets 50, with: - a rivet 50 which passes through the intermediate hole 23 of one of the flanges 20 to be riveted on the pivoting orifice of one side of the upright 3; and another rivet 50 which passes through the intermediate hole 23 of the other flange 20 to be riveted on the pivoting orifice on the other side of the upright 3.

On the shoe 2, in the situation, the flanges 2 are assembled together, and also assembled with the offset arm 4. As such, the railing 1 comprises at least one lower clamping system 6 passing through the flanges 20 and the offset arm 4, and more specifically through the lower hole (s) 22 of the flanges and the orifice (s) 40 of the offset arm 4. As an example, the shoe 2 comprises two lower clamping systems 6, with a system of lower clamping 5 associated with an orifice 40 and another lower clamping system 6 associated with another orifice 40. By way of example, the or each lower clamping system 6 comprises two rivets 60, with a rivet 60 which passes through a hole 22 of one of the flanges 20 to rivet on the orifice 40 on one side of the offset arm 4 and another rivet 60 which passes through a lower hole 22 of the other flange 20 to rivet on the port 40 on the other side of 4. Alternatively, the or each lower clamping system 6 consists of a self-drilling screw or a screw-nut assembly.

In addition, the flanges 2 are assembled with the upright 3, by means of the pivot axis 5 (and its two rivets 50), but also by means of an upper clamping system 7 passing through the flanges 20 and the upright 3, where this upper clamping system 7 comprises a threaded rod 71 passing through the corresponding upper holes 24, 25 or 26 of the flanges 20 and one of the orifices 31, 32 of the upright 3. This upper clamping system 7 also comprises a nut 72 screwed onto the threaded rod 71. It should be noted that the threaded rod 71 has a diameter slightly smaller than the diameters of the holes 25, 26 and the width of the hole 24.

Three configurations are possible: a first configuration (visible in FIGS. 1, 2, 3) in which the threaded rod 71 passes through the first upper secondary holes 25 of the flanges 20 and the secondary orifice 32 of the upright 3 which are aligned, where the amount 3 is blocked at a vertical inclination (in other words in the vertical direction Z); a second configuration (visible in FIG. 5) in which the threaded rod 71 passes through the second upper secondary holes 26 of the flanges 20 and the secondary orifice 32 of the upright 3 which are aligned, where the upright 3 is locked in a non-inclination vertical and non-horizontal with an angle AN with respect to the vertical direction Z; and a third configuration (visible in FIGS. 6, 7 and 8) in which the threaded rod 71 passes through the main upper holes 24 of the flanges 20 and the main orifice 31 of the upright 3 which are aligned, where the upright 3 can be blocked according to an adjustable inclination according to the position of the threaded rod 71 between the upper ends 241 and lower 242 of the upper main holes 24.

In the third configuration, the threaded rod 71 is free to slide in the upper main holes 24, between the upper ends 241 and lower 242, when the nut 72 is loosened and when the upright 3 pivots (as shown by the arrow PI on Figure 6). For a locking of the amount 3 in vertical position, it is still preferable to use the first configuration.

As can be seen in FIG. 3, the railing 1 may also comprise a baseboard 8 fixed on the vertical flanges 27 of the flanges 20 of the shoe 2, by means of screws 80 (in particular of the self-drilling screw type) which pass through the lights 270. respective vertical wings 27. These lights 270 being oblong in a vertical direction Z, it is possible to adjust vertically the position of the baseboard 8 on the shoe 2, as shown schematically by the arrow VE in Figure 3.

As can be seen in FIGS. 1, 2, 3, 4 and 8, the railing 1 may also comprise a shoe 9 fixed on the underside of the shoe 2, so that the shoe 2 will not bear directly on the structure of the shoe. construction, but via this pad 9.
