Abstract
A portable structure for use in building pipelines and the like including an inflatable flexible elongated structure having sides and open ends, support track means operably engaged with each side of said structure and extending the structure length, and a plurality of anchor means or assemblies thereof, each including a device to engage the track means, a part of the anchor means engaging the ground to hold the structure against vertical upward movement, but permitting relative movement between the track means and the anchor means so that the structure can be operatively positioned by the anchor means but be movable in relation thereto.
Claims8
A portable inflatable shelter and attaching means therefor comprising
- an inflatable flexible structure of elongate shape and having open ends, and being of arcuate shape in vertical section,
- track means at each side of said structure and extending substantially the length thereof and being operatively secured to said structure, and
- a plurality of movable anchor means each including pivotal devices to engage said track means at spaced portions thereof and hold said structure against vertical upward movement but permitting relative movement between said devices and said track whereby said structure can be operatively positioned by said anchor means but be movable in relation thereto.
A portable inflatable shelter for movement along a continuous work area on the ground surface, as for use in building a pipeline or the like, and attaching means therefor and comprising
- an inflatable flexible structure having an arcuate shape in vertical section and having a top, sides and open ends, and a center axis,
- reenforcing members operatively engaging said structure and extending the width of the structure from one side thereof across the top to the other side thereof, separate reenforcing members engaging spaced portions of said structure,
- a support track at each side of said structure and extending the length thereof, said reenforcing members engaging said support track, and
- a plurality of anchor means movably supported on the ground and each including roller devices to engage said track at spaced portions thereof and hold said flexible structure against vertical upward movement, whereby said structure can be operatively positioned by said anchor means and be moved in a generally axial direction by being moved in relation to said anchor means.
