Abstract
An assembly “(42)” including a fluid levitated caster and a debris scraper “(31)” device positioned external to a levitation membrane “(11)”. Assembly “(42)” levitates heavy loads upon a near frictionless pressurized fluid, and also sweeps aside potentially membrane destructive debris “(25)” from a floor “(27)” in the path of movement. The external debris scraper “(31)” function does not noticeably increase movement friction, and does not require increased power air flow or consumption.
Claims6
A fluid levitated caster translating device for sweeping aside debris along a movement path surface, comprising:
- (a) a fluid levitated caster means, including a levitation membrane cooperable with said movement path surface to derive fluidic levitating support for said fluid levitated caster,
- (b) a scraper means vertically slideably attached to said fluid levitated caster external to said levitation membrane in cooperation with said movement path surface so as to afford readily debris sweep aside characteristics to the device.
Dependencies are inferred from the claim text.
