PLATFORM BODY ON AIR CUSHION Russian patent published in 1995 - IPC

FIELD: transport. SUBSTANCE: platform body on air cushion has central unit made up of modules 1 and expanders 2 arranged at sides symmetrically relative to diametrical plane of body in pairs and coupled with central unit by coupling units. Each coupling unit has two rods 3 and tie-up arrangement 4. Ends of rods 3 are connected from inside with one of paired symmetrical expanders 2 and are spaced through distance not exceeding length of rod 3. One of sides of central unit has narrowing trapezium-shaped slot and side of expander 2 adjoining central unit has mating narrowing trapezium-shaped projection. Other side of central unit has narrowing trapezium-shaped projection and adjoining side of expander 2 has narrowing trapezium-shaped slot. Joints 9 of modules 1 and joints 10 of expanders 2 are displaced relative to each other. Rods 3 are connected with arrangement 4. With rods 3 being tied up, above indicated projections get into mating slots, thus forming strong coupling of expanders 2 and modules 1. i. e. form platform body on air cushion. EFFECT: facilitated process of assembling of platform body on air cushion and increased reliability of platform body. 2 cl, 5 dwg
