Abstract

The inflatable arch (2) according to the invention comprises inflatable spindles (10) arranged side by side, each longitudinal end of which is slidably mounted along a deployment path (4, 6). The deployment paths are located in parallel planes (P, Q) inclined with respect to the ground (8).

Description

i

  The present invention relates to inflated arches

  made up of inflatable spindles assembled side by side. The deployment and retraction of this type of vault is carried out by simple inflation and deflation of the spindles. To facilitate deployment and retraction, the longitudinal ends of the spindles are slidably mounted along a deployment path formed

  generally beams fixed to the ground.

  Such arches substantially cover the surface delimited by the ground anchor points of the deployment paths. The object of the present invention is to provide a structure of the type described above which makes it possible to cover large spaces so that the covered surface has a part external to the surface delimited by

  the deployment path anchor points.

  To this end, the subject of the present invention is an inflatable vault comprising inflatable spindles arranged side by side, each longitudinal end of which

  is slidably mounted along a deployment path

  ment, characterized in that the deployment paths are located in parallel planes inclined by

report to the ground.

  According to other characteristics: the deployment paths are formed in an arc centered on an axis perpendicular to the plane containing said paths;

  the diameters of the arcs are different

  annuities; the vault is associated with another similar vault to form a cover with two vaults, a path of

  deployment of the first arch being arranged sensitive-

  tangentially to a deployment path of the second arch; the space delimited between the two deployment paths arranged substantially tangentially comprises a network of members arranged in spacers between said deployment paths to form an arch common to the two arches connecting said deployment paths. The present invention will be better understood on

  reading of the detailed description which follows, made

  by way of example, and with reference to the accompanying drawings in which: FIG. 1 is a schematic view of a side section of a vault according to the invention; Figure 2 is a schematic top view of the vault shown in Figure 1; Figure 3 is a schematic view along arrow F of Figure 1; Figure 4 is a view similar to Figure 1 showing the association of two arches such as

  shown in Figure 1 to form a cover

larger area;

  Figure 5 is a top view of the association

  tion of the two arches shown in Figure 3.

  Figure 6 is a schematic view from above of a cover made using three arches according to the invention. In Figures 1 to 3 there is shown a vault 2 according to the invention, comprising two deployment paths 4 and 6 fixed to the ground 8 and connected by a set of inflatable spindles 10 assembled side by side (see

also figure 2).

  The longitudinal ends of the spindles are slidably mounted along the deployment paths

  4 and 6 to facilitate their deployment.

  Deployment paths 4 and 6, consisting for example of beams, are located in planes P, Q

  parallel inclined to the ground 8.

  The deployment paths 4 and 6 are arcs of a circle whose centers 12 and 14 respectively, are

  located on an X-X axis at an angle a with the ground.

  The angle a is complementary to the angle P of inclination

  origin of the P and Q plans of the deployment paths by

report to the ground.

  Note that in the embodiment shown

  felt in FIG. 1, the deployment paths 4 and

  6 are homothetic with respect to the point S of intersection

tion of the X-X axis with the ground 8.

  However, such a provision is not obligatory.

  roof, the point of homotheticity being able to be above or

below the ground.

  In FIGS. 4 and 5, a section is shown.

  groove made using two inflatable parts 50 and 52 which are associated, each inflatable part being formed by a roof as shown in the figures

1 and 2.

  The two arches 50 and 52 are arranged symmetrically

  ment with respect to a vertical plane, such that the deployment path 54 of the first arch 50 is substantially tangent to the deployment path 56 of the second arch 52 in the region furthest from the ground of the deployment paths 54 and 56 (see also figure). The deployment paths 54 and 56 are connected over their entire length by a network of members 58 forming

an arch.

  The arch can be covered with a suitable canvas or hard cover, to ensure continuity

of the cover.

  Note that a technical gallery (not shown

  ) can be suspended from the arch members in order to receive installations such as lighting, sound, shooting stations, security or sprinkler devices, and others. When such a vault, with technical gallery is arranged above a site that can be discovered and to be lit, the lighting is located closer to the site than in the previously known constructions, which decreases

  the energy consumed to obtain good lighting.

  It should be noted that depending on the location

  imposed on the two vaults 50 and 52, the deployment paths

  ment 54 and 56 can be arranged substantially tangent

  tial in an area different from the area furthest from the ground, for example in an area located

  proximity of the longitudinal ends 60 and 62 respec-

roads 54 and 56.

  It should be noted that a vault according to the invention can be associated with at least two other similar vaults 2 so that one of the deployment paths of a vault is substantially tangent to one of the deployment paths of the two adjacent vaults (see Figure 6),

  the free space between the defined deployment paths-

  sant a substantially triangular arch that can include

  ter also a network of members (not shown).
