Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to inflatable buildings, such as those used in so-called N-discotheques, for example buildings that include sound sources and light sources.

It is an object of the invention to provide an inflatable covering for providing a wall section, an inflatable floor element having an inflatable chamber at least partially delimited therein, and an inflatable floor element arranged in the roof area and fitted with a sound source and/or a light source. An inflatable building having a support member is provided.

In the building according to the invention described below, the floor member consists of two parallel skin parts, of which the second skin part serves as a stepping surface for people inside the building, and the lower skin part comes into contact with the substrate on which the building is erected. A perimeter wall surrounds the floor member, and a waist wall is attached airtight to the edges of the two skin sections. An internal bulkhead is provided within the floor side, the bulkhead connecting the two skin portions in a plurality of regions so as to maintain the two skin portions in a substantially parallel relationship even when fully inflated. do.

The inflatable cover may have a dome shape 1, i.e. a hollow hemisphere when inflated with the edges of the cover fixed around the periphery of the floor member.

The support member is arranged, for example, so that it is at the highest point when the cover is inflated. The support member has an array member, and a plurality of light sources and sound sources can be arranged in a desired array on the array member. The array member is visible to persons inside the ViSS object and is mounted in an appropriately sized opening in the covering material. The support member also includes a support,
The support is larger than the array member when viewed from above and is therefore formed with a flange extending around the periphery of the array member and in sealing contact with the periphery of the opening. Conveniently, this contact can be maintained simply by a pressure greater than atmospheric pressure inside the envelope. This contact is sufficient to prevent undesired air escape and to support the integrity of the array members.

It is effective to maintain the pressure inside the cover at a pressure slightly higher than atmospheric pressure and to control the outflow of air so as to balance the amount of air delivered by the blower that maintains the expanded state.

Advantageously, the air outlet means V'i are provided in the entry/exit region of the cover, and are preferably provided with at least two doors spaced apart along a tunnel communicating with the interior of the means. can.

With this arrangement, even in the event of damage to the shroud material due to accident or vandalism, there is no danger to persons inside the shroud, as shrinkage of the shroud is slow and controlled.

However, if the building is to be erected in an environment where additional support is likely to be required, it may be possible, for example, to install an external support frame with a plurality of support legs, for example three support legs. The support legs may be arranged so that they converge at a point in the upper region proximate the array member of the inflated shroud (or such that the extensions of the longitudinal centerlines of the support legs converge). can. The array members and supports can be elastically attached to the support legs 1 or internal struts can be used.

Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. The description of the accompanying drawings is merely illustrative of the invention and should not be construed as limiting the invention.

The building shown in FIG. 1 has an inflatable covering 2 of flexible sheet material which, when inflated, has a generally hemispherical shape. Floor member 4
Vi is located substantially on the diameter of said hemispherical structure and is joined by an inlet/outlet 6 which has an aerodynamic device.

A support member 8 for the light source and speaker array (see FIG. 3) is supported in position by the internal nitrogen pressure of the inflated cover 2. Air is pumped through the blower 9 to maintain the inflated state of the cover 2 at a pressure slightly greater than atmospheric pressure.

FIG. 2 shows a support member 8 including a support 10. FIG.

P Beast 14 is pressed. Below the support 10 there is an array member 16 to which light sources 18 and sound sources 20 (FIG. 3) of various colors are attached.

The floor member 4 includes a pair of substantially parallel skin portions 22 and 24.
have. An upper skin portion 22 provides a tread surface for persons within the building, and a lower skin portion 24
is placed on the base 26. Base 26 can be any suitable ground surface.

These two skin sections are connected and fixed by a continuous peripheral wall 28 and a web section 30.
H, connecting the skin portions 22.24 at intervals throughout the chamber defined by the skin portions 22.24 and the wall 28; In this way, the expansion of the floor member 4 provides a resilient surface on which it is possible to dance to the music from the speakers 20.

The entrance/exit 6l-jEil to the building in the inflated state consists of a tunnel 32 with a D-shaped cross-section made of flexible material. Conveniently, this material is similar to that of cover 2. Spaced apart loops 34 in tunnel 32 include three half-loop members 38, 38' and 3.
8'' is fixed to the support column 36 of the cage-like support device.

An end wall 40 supported by a half-loop member 38 has a double 72-thickness flap 42 which can be folded back to allow persons wishing to enter the building to enter the tunnel 32. It can be done. When the flap 42 is closed, the folding door 4 is made of elastic sheet material reinforced with suitable reinforcing ribs and supported by half-loop members 38''.
You can open 4 and go inside.

In this embodiment, air escape from the inflated building is achieved by leaving a gap of about 0.09i (approximately 1 square foot) for air escape without completely closing the folding door 44, as described above. It is convenient to control.

Various modifications can be made within the scope of the invention.

For example, a flexible plastic window can be installed in the tunnel 32.

Other locations can also be used for air outflow control.

In the case of a second embodiment of the building according to the invention shown in FIGS. 5 and 6, an inflatable cover 4 having a similar construction to the cover 2
6, the floor member 48 is attached.

Access to the inside of the building is through an opening 50 in the wall of the cover 46.
Use. The opening is provided with a flexible folding blind device 52.
It is equipped with an aerodynamic device including.

This blind device fC: 52 has a rod/handle 54 L7 and can be opened by lifting the handle 54 upwards.

As shown in FIG. 6, within the building, array members 56 and their supports are held in place by vertical struts 58. Vertical post 58 is conveniently located in the center of floor member 48 in this embodiment. To prevent a friend from getting injured if he or she hits the pillar 58, the pillar 58t/l-j protective cushion 60 is placed 1jfff.

The use of flexible plastic window 62 is optional.
