Definitions

  • the embodiments described herein relate to a portable and collapsible barrier unit that is lightweight and can be easily transported and erected.
  • the barrier unit includes a diaphragm that can be expanded with a medium to a desired shape that will act as a barrier.
  • Each barrier unit can be used alone or with other barrier units to create a wall.
  • saw horses or metal gates are sometimes used to contain crowds.
  • a problem with saw horses, metal gates and other similar barriers is they can not contain bulk materials and liquids such as soil, grain or water.
  • Such bulk materials and liquids require barriers that, for example, can span large distances, can hold back the weight of bulk materials and liquids and do not have any holes that would allow the bulk materials or liquids to pass through the barrier.
  • Each barrier unit has a rigid base, which can be a carrying case with a top, and an inflatable enclosed volume such as a flexible diaphragm that rests on the base.
  • the side walls of the volume can have any constructions such as an accordionlike construction.
  • the volume can be secured to the base.
  • the volume will have an inlet hole through which a medium such as a gas or liquid can be pumped into the volume to inflate the volume. When the volume is inflated, the volume will act as a barrier for holding back bulk materials or liquids.
  • Each barrier unit can be anchored using, for example, ballast.
  • a number of barrier units can be connected together to form a wall or corral.
  • the barriers can be connected using any conventional techniques.
  • the barrier units can be sealed together using any conventional technique to prevent bulk materials or liquids from seeping between the barrier units.

  • Each enclosed volume of each barrier unit can be connected to separate mediums sources or can be connected in parallel to the same medium source.
  • the volumes of the barrier units can be connected in series so the medium enters one volume to inflate that volume and then can exit that volume and enter the next volume to inflate that volume and then continue on to the other volumes.

Abstract

La présente invention concerne une barrière portable et pliable qui est légère et peut être facilement transportée et érigée. La barrière comprend une base, un haut et un volume fermé tel qu'un diaphragme qui peut être élargi à l'aide d'un médium tel qu'un gaz ou un liquide selon la forme souhaité par un utilisateur. Le volume élargi agira comme une barrière. Lorsqu'une série de barrières élargies sont raccordées, elles formeront un mur qui peut contenir des matériaux en vrac ou des liquides.
