Optional features of the invention, complementary or substitution are set forth below. The step of attaching the first end of each upright to its foot may include:

A sub-step of fixing the first end to a hinge formed on the foot,

A substep of adjustment of the amount,

A substep of locking the first end on the foot. The step of coupling each of the ends of the span with its associated slide link may include inserting a termination of the dovetail shaped span into a groove on a portion of the length of the studs. The step of actuating the lifting gear can comprise for each amount the operation of a winch for winding a cable flowing from said winch to the end of the span through a pulley mechanism fixed at the level of the second end of the amount. Other advantages and particularities of the invention will appear on reading the detailed description of implementations and non-limiting embodiments, and the following appended drawings: FIG. 1 is a view of a set of an arch self-supporting according to one embodiment of the invention. Figures 2 to 5 are detail views of the self-supporting arch according to various embodiments of the invention. Figure 6 a view of a mounting method of the self-supporting arch according to one embodiment of the invention. Figures 7A and 7B are each a view of a possible application of the self-supporting arch of the invention.

Figure 1 shows a self-supporting structure of the type "arch". Freestanding means that the structure can stand up in its assigned form without the addition of additional elements.

This structure comprises a span 4 having a first 41 and a second end 42, two rigid uprights 2, 2 'each also having a first 23, 23' and a second end 24, 24 '.

Of course, the structure could be extended with other amounts and other spans that would give it other forms than that of an arch.

The structure also comprises two feet 3, 3 'able to accommodate each the first end 23, 23' of the uprights 2, 2 'with fixing means.

The amounts 2, 2 'each comprise means capable of forming a slide connection over a major portion of their length with each end of the span.

Lifting devices 50, 51 are provided on each upright to actuate the sliding of the ends of the span along said uprights.

Advantageously and by way of illustration as shown in FIGS. 2 and 3, the lifting devices for actuating the sliding of the ends of the span along the uprights consist of a winch 50 and a pulley mechanism allowing the winding and unwinding of a cable 56 retaining the ends of the span each mounted sliding along its respective amount.

FIG. 3 illustrates a preferred embodiment using a compound pulley 51, comprising two groups 52, 53 fixed for the first to the second end 24, 24 'of the upright by means of a fastener 54 and fixed for the second to end of the bay engaged with the sliding connection of the amount, according to a clip 55. This type of pulley can reduce by half the efforts to lift the span. Other configurations are possible with motion transmission mechanisms consisting of two groups, one fixed, the other mobile, each containing an arbitrary number of pulleys, and a rope that connects them. These mechanisms also known as "hoists" make it possible to increase the force used to lift a heavy span.

The means for forming the slide connection consist of a groove 21 formed on almost the entire length of the face of the upright 22, 22 'located on the side of the span. This groove 21 extends to the end 24, 24 'of the upright so as to guide the cable that descends along the face opposite to the face of the upright 21, 21' located on the side of the span, to the winch 50.

Advantageously, the fixing means of the feet 3, 3 'able to accommodate the first end 23, 23' of the uprights comprise a hinge and locking means. The hinge makes it possible to fix the first end 23, 23 'of the uprights to its foot when the upright is in a horizontal position and to straighten the upright without it moving at ground level. The locking means can maintain the upright position once the latter is straightened on his foot.

In order to further stabilize the structure, it may be advantageous to weight the feet.

In order to stabilize the structure, it is also possible, as an alternative or as a complement, to add feet 3, 3 'to ground anchoring means. These anchoring means may be pegs to drive in soft ground or keys when the ground is equipped with a suitable support.

As shown in FIG. 4, the feet 3, 3 'may furthermore comprise adjusting means 30 which make it possible to compensate for differences in level and slope of the floor.

The amounts are the result of an assembly of parallelepiped shaped reinforcements and made of aluminum tubes mechanically welded together.

These frames can be assembled and then disassembled simply, in that they are nestable with each other. This facilitates the transport and storage of the ark, and thus the ark. The amounts are advantageously in three to six parts.

The vertical retention of the arch can be secured with a guying device, the guying means by any operation which consists in securing the amounts using elements (cables, ...) made integral with the amounts and fixed points outside the arch.

As for the amounts and for the purpose of facilitating the transport and storage of the arch, the span is formed by the assembly of parallelepiped shaped frames and formed by aluminum tubes mechanosoudés them.

These frames can be assembled and then disassembled simply, in that they are nestable with each other.

The method of mounting the freestanding structure of the type "arch" is made easy by the design of said arch. As shown in Figure 6, the mounting method does not require the intervention of a machine other than a machine to transport the dismounted arch and does not require the participation of more than two or three people.

It is necessary first of all to convey on the site at least one span 4, two rigid uprights 2, 2 ', two feet 3, 3' each suitable for receiving the first end of the uprights with fastening means, said uprights each comprising means capable of forming a slide connection over a major portion of their length with each end of the span, as well as lifting devices 50, 51 for actuating the sliding of the ends of the span along said uprights.

At first, it is necessary to assemble the frames to form the amounts and the span. Each of these frames is relatively light and weighs between 5 and 30 kg. Thus, the amounts and the span each represent masses between 15 and 60 kg.

Then, it is necessary to position the feet, in particular according to the length of the span, then to fix the first end of each amount on its foot.

Fixing each amount on his foot can be done by inserting the amount on his foot, the amount is already in a vertical position.

In order to limit the number of people to one, it may be advantageous to fix the first end of each amount on his foot by means of a ball joint, the amount then being in a lying position. The sole intervener must then raise the amount in a vertical position and fix it permanently on his foot. The lifting of the upright can then advantageously be accomplished with hydraulic means such as a jack, and this, in order to ease the efforts of the single speaker.

Then, one proceeds to the coupling of each end of the bay with its associated slide link on the amount.

Finally, it is possible to operate the lifting gear so as to lift the span vertically. The step of operating the lifting gear can consist for each amount to actuate a winch for winding a cable flowing from said winch to the end of the span through a pulley mechanism fixed at the second end the amount.

When the means for fixing the feet comprise a hinge and locking means, the step of fixing the first end of each upright on its foot comprises a substep of fixing the first end to a hinge formed on the foot, then a sub-step of straightening the amount, and finally a substep of locking the first end on the foot.

In order to secure the slide connection, the step of coupling each of the ends of the span with its associated slide linkage may advantageously include the insertion of a termination of the dovetail-shaped span into a groove on a groove. part of the length of the uprights.

According to a first application shown in FIG. 7A, the span is rigid and in the image of the uprights. The amounts and span are covered at least partly with an envelope that can wear colors, a slogan, the name of a company or event.

According to a second application shown in FIG. 7B, the span is a streamer.

Of course, the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention. In addition, the various features, shapes, variants and embodiments of the invention may be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.
