Abstract
A vehicle, designed to move across an external curved surface such as that of a pipe or cable, for example to monitor the condition of the surface or enable the application of a treatment to the surface, comprises two generally hollow bodies, interconnected by means to move the bodies towards and away from each other, each body having generally parallel, generally flat resilient members each having a generally central aperture, which apertures are in general alignment.
Claims15
A surface-traversing vehicle which comprises two generally hollow bodies interconnected by means to move the bodies towards and away from each other, each said body having a plurality of generally parallel, generally flat resilient members extending across the interior of the body, each said resilient member having an aperture within the region of the centre thereof, the apertures within each body being in general alignment.
A surface-traversing vehicle which comprises two generally hollow bodies interconnected by means to move the bodies towards and away from each other, each said body having a plurality of generally parallel, generally flat resilient members extending across the interior of said body and formed of a material selected from the group consisting of natural rubber, synthetic rubber, and polymeric material, each said resilient member having an aperture within the region of its centre, the apertures within each said body being in general alignment.
A surface-traversing vehicle which comprises two generally hollow bodies interconnected by means to move the bodies towards and away from each other, each said body having a plurality of generally parallel, generally flat resilient members extending across the interior of said body and formed of a resilient metal, each said resilient member having an aperture within the region of its centre, the apertures within each said body being in general alignment.
A surface-traversing vehicle which comprises two generally hollow bodies interconnected by means to move the bodies towards and away from each other, each said body having a plurality of generally parallel, generally flat resilient members extending across the interior of said body, each said resilient member having an aperture within the region of its centre, the apertures in each body being generally aligned with each other, at least one of said generally hollow bodies further having means to grip the surface being traversed by the vehicle, whereby to enable the direction of traverse to be reversed.
