The pins used in the invention, in particular the pins 10b, 10c, 10d and 1 lb, 11d, are of the self-locking type or are provided with anti-loosening devices.

Figure 2 illustrates another variant of the device according to the invention, adapted to rest on the ground. This variant comprises a single upright 10, telescopic, comprising at its base a base 14 to ensure its stability, and supports at its upper end a receptacle 12. In another embodiment, this variant comprises two amounts sharing a common base or having each one has its own base.

Figure 3A illustrates an embodiment of the receptacle 12 adapted to fit on the device having two uprights. In this embodiment, the receptacle 12 comprises a cradle 15 elongate along a longitudinal axis YY, whose cross section has substantially the shape of a circle segment and receives a roll of wallpaper 16. This cradle 15 is made of material lightweight to limit weight in height, for example using an aluminum plate or plastic or composite material. In another embodiment not shown, this cradle may be limited to a metal trellis or other, the important thing is that its length and its curved shape allow it to receive the strips or rolls of paper to ask 16. The cradle 15 comprises in addition two supports 10e, 1 the extending substantially radially and downwardly from an underside of the cradle, the supports 10e and 11e being adapted to cooperate with the uprights 10a and 11a of the device: • these supports can be sleeves adapted to receive the amounts l0a and 1 la if they are full, • they can be solid rods which fit into the amounts l0a and 11a if they are hollow.

This embodiment of the receptacle 12 is easily adaptable to a configuration of the device as shown in Figure 2 where the device has only one amount. In this case, a single support is provided on the surface of the cradle 15, in the plane of symmetry transverse to the cradle. On its surface, the cradle 15 comprises rollers 17 mounted to pivot freely about axes 18 parallel to the axis YY of the cradle 15. In the illustrated embodiment, the cradle 15 has openings 19 of a size slightly greater than that of the cradles 15. rollers 17, and the shafts 18 are mounted integral with the outer surface of the cradle 15 so as to partially obscure a respective opening 19. Furthermore, the radius of the rollers 17 is greater than the thickness of the material plate which constitutes the cradle 15.

In this way, the rollers 17 take place in a respective opening 19 and protrude inside the cradle 15; the lé or the roll 16 disposed in the cradle 15 thus rests on the rollers and not on the cradle itself. To ensure a good rotational guidance of the roller 16, the cradle 15 comprises four rollers 17, arranged in pairs near each end of the cradle 15 and substantially symmetrically with respect to the plane of symmetry of the cradle 15. In the variant where the cradle consists of a lattice, the rollers 17 are simply rotatably mounted on branches of the lattice parallel to the axis YY of the cradle 15. FIG. 3B illustrates an embodiment of a pressing device 20 able to hold a web or a roll of wallpaper 16 in the cradle 15. The device 20 comprises two metal branches in the form of parallel circular arcs 21a and 21b, joined by two orthogonal segments to the plane of the arcs of a circle, a segment 22 located at one of their ends and a segment 23 located in the vicinity of the middle of the branches 21a and 21b. At their other end, the branches 21a and 21b are each extended by a rod 24a, 24b, orthogonal to the plane of the arcs and which extend in opposite directions. Moreover, fixing lugs 25a, 25b are fixed on the outer surface and in the vicinity of an edge of the cradle 15, and comprise a tab orthogonal to the surface of the cradle 15. The rods 24a and 24b are pivotally mounted each in a hole formed in a respective tongue, parallel to the axis YY of the cradle 15. Two springs 26a, 26b mounted on a respective rod 24a, 24b, bearing on the cradle 15 and a respective branch 21a, 21b recall the device 20 to inside the cradle. The branches in circular arcs 21a and 21b follow the shape of a roller 16 disposed in the cradle 15 and the device 20 is therefore able to hold the roller 16 inside the cradle 15. In order to facilitate the rotation of the roller of wallpaper 16, rollers 27 are rotatably mounted on the segments 22 and 23 which are, like the rods 24a and 24b, parallel to the axis YY of the cradle 15.

The rollers 17, 27 rotatably mounted on the cradle 15 and the pressing device 20 also have the function of preventing any friction of the wallpaper against a rigid object, the cradle or parts of the pressing device, which could damage the face visible from the paper. Figure 7 illustrates another embodiment of the receptacle 12 adapted to fit on the support means of a device according to the invention comprising two amounts. In this embodiment, the receptacle is in the form of a split tube 40, preferably of light material having a horizontal Y-Y horizontal axis. The slot is provided over the entire length of the tube, so as to form a reel for a web or roller 16 placed inside the split tube 40. As for the first embodiment, the reel has in its lower part rollers 17 to facilitate the rotation of the roller 16 inside the reel, as well as supports 10e and 11c able to cooperate with the uprights 10a and 11a of the device The tube 40 and the supports 10e and 11e may comprise means which cooperate to allow the tube 40 to be pivoted about its axis YY between two limit angles, so as to orient the slot 41 according to the preferred direction of unfolding paper. These means may comprise one or two slides arranged in an arc of a circle on the outer surface of the tube 40. This embodiment may also be provided to fit on a device comprising only one amount as illustrated by FIG. figure 2.

The device 1 is removable to facilitate its transport. When used in conjunction with a stepladder 2, it is advantageous to ensure that in particular the amounts 10 and 11 can be stored closer to the stepladder. FIG. 4 illustrates an embodiment of means making it possible to associate the upright 10 of the device 1 with the step stool 2. As has been seen above, the upright 10 has openings 01, 02 and 03. The stringer 3 comprises openings P1, P2, P3 which correspond to those of the upright 10 when it is applied laterally against the bar 3, so as to secure the upright and the smooth when pins 10c, 10d and 10b are introduced into these openings. Identical means are provided on the rail 4 to fix the upright 11.

FIGS. 5A to 5C illustrate an embodiment of a stepladder 2 comprising a device 1 comprising two uprights and their deployment.

Sleeves are provided laterally along the rail 3 in which the upright 10 can slide: • a sleeve 30 at its lower end, • an intermediate sleeve 31 in the vicinity of one third of its height, • a sleeve 32 at its upper end, pivoted about an axis parallel to the bars 5 of the stool.

In its storage position, the upright 10 is aligned along the rail 3 and occupies the sleeves 30, 31 and 32 (Figure 5A). To deploy the upright 10, it is pulled upwards, which releases it from the lower sleeve 30, until its lower end is disengaged from the intermediate sleeve 31 but not from the end sleeve 32; it is then erected vertically by pivoting it about the axis of rotation of the sleeve 32 (Figure 5B). Once the upright 10 in a vertical position, its lower end takes place in a support 33 provided along the stand 7 (Figure 5C). Then the receptacle 12 is attached to the upper end of the uprights 10 and 11. These uprights are telescopic so as to adjust the height of this receptacle.

FIGS. 6A to 6C illustrate another embodiment of a stepladder 52 comprising a device 1 and the deployment of the uprights. The heddle 3 comprises at its upper end a hinge 34 whose axis is parallel to the bars 5, and which connects the heal 3 and one end of the upright 10. In the storage position, it rests on the hed 3 (Figure 6A ). To deploy the post 10, it pivots around the hinge 34 to a vertical position (Figure 6B). A locking piece 35 is attached to the rail 3 and the upright 10 to maintain the latter in a vertical position (Figure 6C). This locking piece 35 can itself be stored along the stand 7 when it is not used (Figure 6A). 15
