Device for delimiting the course of a circuit

Abstract

A device for delimiting the course of a circuit includes an inflatable structure formed of tubular pieces. The tubular pieces are made of a flexible material and can be interconnected as to form exterior sections, interior sections and interconnecting bridges therebetween. The device further includes means for fastening the inflatable structure to the ground.

1 . A device for delimiting the course of a circuit, thereby characterized by including an inflatable structure ( 1 ) made up of tubular pieces ( 2 ) of flexible material that can be interconnected and that make up exterior sections ( 3 ), interior sections ( 4 ), and interconnecting bridges ( 5 ) between the exterior and interior sections ( 3  and  4 ). They thereby delimit the circuit course between the mentioned sections. The device includes a means of fastening the inflatable structure ( 1 ) to the ground.  
     
     
         2 . A device, in accordance with the preceding independent claim, characterized by tubular pieces ( 2 ) that each present end openings ( 2   a ) for the longitudinal connection of successive tubular pieces and, optionally, that present radial openings ( 2   b ) for connecting tubular pieces perpendicular to the longitudinal ones.  
     
     
         3 . A device, in accordance with the preceding independent claims, characterized by at least one of the tubular pieces ( 2 ) presenting an inflation opening ( 2   c ).  
     
     
         4 . A device, in accordance with the preceding independent claims, characterized by the end openings ( 2   a ) and the radial openings ( 2   b ) having a means for interconnection.  
     
     
         5 . A device, in accordance with independent claim number  4 , characterized by the means of interconnecting the tubular pieces ( 2 ) being made up of perimeter strips ( 6 ) set around the openings ( 2   a  and  2   b ) and by a removable strip ( 7 ) designed to externally grip the perimeter strips ( 6 ). The perimeter strips ( 6 ) and the removable strips ( 7 ) thereby make up the complimentary parts of a contact seal.  
     
     
         6 . A device, in accordance with the preceding independent claims, characterized by the tubular pieces ( 2 ) presenting fastening loops ( 2   d ) that are aligned along the sides for hooking the means for fastening the inflatable structure ( 1 ) to the ground.  
     
     
         7 . A device, in accordance with the preceding independent claims, characterized by the means of fastening the inflatable structure ( 1 ) to the ground being made up of a strong cable or rope ( 8 ) that passes through the fastening loops ( 2   d ) and which is fastened in the desired position using lateral tensors ( 9 ) anchored to the ground.
