Inflatable streamlining structure for vehicles

Claim 2

A structure for streamlining vehicles comprising: a. an inflatable body comprising when inflated a substantially continuous tube defining the perimeter of said streamlining structure; b. a substantially continuous skirt attached to the perimeter of said inflatable body and attachable to the sides of a vehicle adjacent one end thereof to define a substantially continuous fairing between said one end of said vehicle and said inflatable body when the latter is inflated.

Claim 3

Structure according to claim 1 wherein said substantially continuous tube defines a central opening, and including a second inflatable body spanning said opening and disposed on the side of said tubular member remote from a vehicle to which said streamlining structure is attached such that a portion of said second inflatable body protrudes from said opening beyond the said first inflatable body to define a smoothly contoured wind-breaking surface.

Claim 4

Structure according to claim 2 wherein a portion of said second inflatable body and said skirt are defined by a continuous sheet member.

Claim 5

Structure according to claim 3 wherein said tube defines a substantially rectangular frame and said second inflatable body is generally rectangular and lenticular when inflated, whereby said inflatable bodies together are generally rectangular in planform and streamlined in cross section.

Claim 6

Structure according to claim 2 and including a continuous inflatable inner tube disposed forward of and tangentially contacting the firstmentioned tube and said second inflatable body.

Claim 7

Structure according to claim 5 and including a flexible sheet disposed on the non-streamlined side of said structure and connected to said firstmentioned inflatable tube along the substantial length thereof to restrain same from divergent movement.

Claim 8

Structure according to claim 2 and including a flexible sheet covering said continuous tube and second inflatable body on the windward side thereof.

Claim 9

Structure according to claim 1 wherein said structure includes a plurality of inflatable parallel ribs.

Claim 10

A structure for streamlining vehicles comprising: a. a generally lenticular inflatable body; b. a substantially continuous skirt attached to the perimeter of said inflatable body and attachable to the sides of a vehicle adjacent one end thereof to define a substantially continuous fairing between said one end of said vehicle and said inflatable body when the latter is inflated; and c. means for supporting the perimeter of said inflatable body in spaced relation to one end of a vehicle to maintain said skirt in taut condition.

Claim 11

A structure for streamlining vehicles comprising: a. a generally lenticular inflatable body; b. a substantially continuous skirt attached to the perimeter of said inflatable body and attachable to the sides of a vehicle adjacent one end thereof to define a substantially continuous fairing between said one end of said vehicle and said inflatable body when the latter is inflated; and c. means for supporting the perimeter of said inflatable body in spaced relation to one end of a vehicle to maintain said skirt in taut condition.

Claim 12

A structure for streamlining vehicles comprising: a. a first flexible member comprising an inflatable body having a shape when inflated substantially determined by the pressure within said body; b. a second flexible member comprising a sheet dimensioned to cover said inflatable body and retain same on one end of a moving vehicle; c. means for attaching said sheet to the sides of a vehicle adjacent one end thereof whereby the protruding shape defined by said inflatable body is faired smoothly to an end of the moving vehicle to which it is attached.

Claim 13

A structure for streamlining vehicles comprising: a. a first flexible member comprising an inflatable body having a shape when inflated substantially determined by the pressure within said body; b. a second flexible member comprising a sheet dimensioned to cover said inflatable body and retain same on one end of a moving vehicle; c. means for attaching said sheet to the sides of a vehicle adjacent one end thereof whereby the protruding shape defined by said inflatable body is faired smoothly to an end of the moving vehicle to which it is attached.
