Abstract

A bracket (10) for a staircase consists of a tubular arm (11) arranged between the underside (21) of a step (20) and the side surface (32 or 33) of the string (30). The ends of the arm (11) have collars or rings (12, 13) for embedding in respective recesses (22, 23 and 34, 35) provided in the underside (21) of the step and in the side surfaces (32, 33) of the string (30). A complementary fastening element (15) connects the back of the step to the top surface (31) of the string.

Description

Stair console

The present invention is in the field of construction and relates more particularly to a staircase.

In order to lighten the construction, stairs are often made without steps, the plates of which form the steps are placed between two stringers.

Stairs with a central stringer are also known on which the steps are fixed, directly or not. By construction, this stringer is an inclined component, and it is necessary to provide means for fixing the horizontal plates constituting the steps, for example with cutouts having a horizontal part intended to receive the step directly. When a staircase is not made by hand, it is necessary to know precisely in advance the height separating the two levels to be connected by a staircase, so that the steps are distributed and their height ^" remains constant with respect to the adjacent walk. known devices are not adaptable on site and the present invention aims to overcome this drawback.

It therefore relates to a staircase console characterized by an inclined arm disposed between the step and a lateral face of the stringer, so as to constitute a triangulation.

In a preferred variant, the inclined arm is constituted by a tubular part, the ends of which have shaped parts capable of being embedded in the material forming the step and the stringer.

The invention also extends to a method of mounting a staircase according to which a stringer is put in place between the levels to be reached by said staircase, clearances are made in its lateral faces, each clearance being able to receive the lower end of a console according to the invention, the spacing between the clearances being defined by the regular distribution of the steps.

The appended drawing represents, by way of nonlimiting example, an embodiment of the object of the present invention.

Figure 1 is a partial perspective view of some steps constituting a staircase according to the pré¬ invention.

Figure 2 is a side view.

Figure 3 is a front view of the staircase of Figure 1. In the drawing, consoles 10 are shown, placed between steps 20 and a stringer 30.

More specifically, and as visible in the front view of FIG. 3, each console 10 is constituted by a tubular arm 11, each end of which comprises a shaped part 12, 13 intended to ensure its fixing in the step 20 and the stringer 30 respectively to stabilize the construction by triangulation.

In the variant shown in the drawing, the part 12 or 13 is formed by a washer welded to each end of the tube and intended to be embedded in a corresponding clearance. The assembly is ensured by any fixing means, for example screws 14, visible in FIGS. 1 and 2.

Each step 20 is constituted by a plate whose lower surface 21 has two clearances 22, 23 intended to receive the parts 12 or 13 already described.

Preferably, the clearances 22 and 23 are relatively close to the front face 24 of the step, while the rear face 25 rests on the stringer 30. In addition, a central complementary piece 15 can be provided, shown in FIGS. 2 and 3 , and intended to improve the seat of the assembly by ensuring the fixing of the rear 25 of the step directly in the central stringer 30.

The central stringer is constituted by a profile 30 disposed between the two levels to be connected by the staircase according to the invention. The profile shown in the drawing is of rectangular section. It has a upper face 31 intended to receive the steps 20 and lateral faces 32 and 33 cooperating with the consoles 10.

After having fixed the profile 30 in the stairwell, we will determine the number of steps necessary to go from one level to another, and we will decide their location along the profile (s) 30. We will practice, at regular intervals, clearances 34 and 35 intended to receive the lower ends 13 of the tubes 11, which are fixed by screws 14 as mentioned above.

As indicated in the introduction, this way of making it possible to use components manufactured in series and adaptable to all the spacings required by each particular case. The staircase console according to the invention also allows the realization of any type of staircase, for example rounded or angled, according to the given shape - to the support stringer.

Alternatively, provision can be made to place the steps asymmetrically with respect to the central stringer. It may be necessary in this case to use consoles according to the invention different on each side of the system.

Claims
