FR2666017A1 - Inflatable structure permitting climbing - Google Patents

Abstract

By virtue of the fastening of rigid elements on an inflated PVC-fabric membrane, a volume of random shapes is obtained, adapted to climbing.

Description

The inflatable structure allows the practice of climbing.
FIG. I AND FIG.Ii
The principle consists in @ontler The PVC membrane in order to obtain a freestanding block whose shapes can vary
This member (3) is previously equipped on its internal surface with rectangular plates (b) made of metal, wood or plastic or other materials. The dimensions of these plates are variable in width and in length. These plates have at their center a gridding (7) of variable diameter allowing the screwing from the outside of rigid elements (1) (climbing holds) on which iL will be possible to take support to allow the ascent.

FIG. III
The plates (@) are arranged in a frame from s0 cm to 5 cm and fixed to the internal surface of the membrane (3) by a membrane (@) of the same type glued hot by welding @ high frequency in order to ensure the stability of the plate (b) and. sealing.

The stability and the shapes given to the self-stable inflated blocks are made from cables (@) stretched inside the blocks and fixed from one side to the other. FIG @@@.

The cables (4) are fixed on plates (2) identical to those allowing the @ixation of the @ixes elements (1). FIG. 111
The membrane (3) constituting The outer casing is of the type
PVC the weight varies from 500 g / M2 to 1,700 g / M2. FIG. l.

 This is inflated to a suttisante pressure (2 to @ bars) to obtain a rigid wall.

The gontleur is an electric motor driving a fan producing air. It can always be turned on to compensate for pressure losses.

By way of nonlimiting example, we will describe below a prototype which has been produced according to the invention.

It is of an inflated block of wall type leaning on a
existing wall, by flexible legs passed through a tube
metallic read @ - even sealed to the existing wall. FIG. I.

The height of the inflated block is 4.00 m, the width of the block
inflated is 2.40 m the thickness of the inflated block is 0.80 m.

 FIG. T AND FIG. He.

The frame for fixing the external sockets (I) is
0.40 x 0.40 m or 50 sockets. FIG.I
These sockets (1) are fixed from the outside by screwing
the male part of the socket on the real @ s @ e female part in
the aluminum plate (5) fixed on the internal surface of the
PVC membrane (3)
The rigidity of the PVC membrane is obtained by @ on @@ age at a pressure of 2.4 bars.

The torch @e the membrane (3) is maintained and @@ held by the
fixing inside the inflated volume 8 cables (4) stretched
@ 'a patch to another of the mem @ rane (3) frame of @, 80 x 0.80.

 FIG. 11.

The ends of these cables are screwed onto plates (2)
fixed on the inside of the membrane. The lettering of the plates being in this case turns to the interior or volume.

 FIG. III.

The plates (2) used for fixing the cables (4)
@interiors and sockets (1) are rea @@ sees en
aluminum with a diameter of 10 mm for sockets
and @ mm for cables @ ntér @ eurs.FIG. III.

They are fixed on the membrane (3) tormant PVC
the envelope by wrapping a PVC mem @ rane (@)

These enveloping membranes (@) thus ensure @ la @@ x @@@@@ @es
plates (2) (5) and the waterproof @ te @u volume.

The pr @ ses d'es @ ai @ e are assured of @e @as turn on
themselves by the fr @ ction carried out at serra @ e en @ re on

and the PVC membrane (3).

The inflatable blocks rea @@ ses for the esca @ ade are these forms
varied and include overhangs, inclined planes.

Claims (3)

 1) Climbing structure,. comprising artificial holds (1) characterized by the fact that it consists of an inflated membrane (3) on which the climbing holds (1) are fixed comprising two parts one outside (1) ( male part) the other inside (5) (female part) of the membrane (3). 2) Device according to claim (1) characterized in that each climbing hold consists of a plate (5) of rigid materials located inside the inflatable volume and having a threaded female part (7) intended for receive the male part of the socket (1) after it has passed through the inflated envelope as well as the threading (7) of the internal tension cables (4) ensuring the shape of the volumes. Fig 11. 3) Device according to claim (1) characterized in that the plates (2) (5) are fixed to the membrane (3) forming an envelope by hot bonding of a membrane (6) of the same nature as the membrane ( 3) envelope thus ensuring the fixing of the plates (2) (5) and the sealing of the volume.
