Abstract
A mono-air-cell body made of a flexible elastic material and having a hollow interior and no less than one connecting tube for connecting different mono-air-cell bodies together one after another, for making up a shock-absorbing cushion. Each mono-air-cell body can have any shape in its top plan view. Each connecting tube can be a male one having at least one round circumferential groove or a female one having at least one round circumferential ridge so that the male and the female connecting tubes can be joined together, thereby connecting two mono-air-cell bodies together. The shock-absorbing cushion can be composed to have a shape of a band, a plane, a sphere or any three-dimensional shape.
Claims17
A shock-absorbing unit, comprising:
- a hollow body having flexible, elastic walls bounding an interior which contains a compressible fluid medium, said body having a first, hollow connecting tube in fluid communication with the interior, said first connecting tube being integral with, and extending upwardly beyond, one of the walls, said first connecting tube having a first fastener thereon, said body having a second, hollow connecting tube in fluid communication with the interior, said second connecting tube being integral with, and extending outwardly beyond, another of the walls, said second connecting tube having thereon a second fastener, each connecting tube having a frusto-conical shape with a maximum diameter at a junction between the tube and the wall with which the tube is integral and being constituted of the same material as the walls of the body, one of said tubes being selectively movable inwardly and outwardly of a respective wall of the body to form an inwardly extending female connecting tube or an outwardly extending male connecting tube for connection respectively to a corresponding male or female connecting tube of another shock-absorbing unit.
A shock-absorbing structure, comprising:
- a plurality of shock-absorbing units, each including a hollow body having flexible, elastic walls bounding an interior which contains a compressible fluid medium, said plurality including a first body having a first, hollow connecting tube in fluid communication with the interior of the first body, said first connecting tube being integral with, and extending outwardly beyond, one of the walls of the first body, said first connecting tube having a first fastener thereon, said plurality including a second body having a second, hollow connecting tube in fluid communication with the interior of the second body, said second connecting tube being integral with one of the walls of the second body and having a second fastener thereon, each connecting tube having a frusto-conical shape with a maximum diameter at a junction between the tube and the respective wall with which the tube is integral and being constituted of the same material as the walls of the respective body, said second tube being selectively movable between outer and inner positions in which the second tube respective extends outwardly and inwardly of the second body to form a male or female connecting tube respectively, said first and second fasteners detachably mating with each other to form the structure with a predetermined configuration.
