Abstract
The invention relates to a volume element (10) comprising at least one inner chamber (12), which is bordered by an at least substantially flexible material and which can be inflated with a gas, and comprising at least one outer chamber (14), which is bordered by an at least substantially flexible material, which is fluidically separated from the at least one inner chamber (12), and which surrounds at least some regions of the outer circumference of the inner chamber (12). Granular material is received in the outer chamber (14) for absorbing pressure forces acting on the volume element (10) from the direction of the outer chamber (14).
Claims10
Volume element (10) including at least one inner chamber (12) bordered by an at least substantially flexible material, which is inflatable with a gas, and including at least one outer chamber (14) bordered by an at least substantially flexible material, which is fluidically separated from the at least one inner chamber (12), and by which the inner chamber (12) is surrounded on the outer circumference at least in certain regions,
- characterized in that
- granular material for absorbing pressure forces acting on the volume element (10) from the direction of the outer chamber (14) is received in the outer chamber (14).
Volume element (10) according to any one of the preceding claims,
- characterized in that
- at least one second outer chamber (14) fluidically separated from the first outer chamber (14) at least in certain regions is provided, wherein the inner chamber (12) is surrounded by one of the two outer chambers (14) on a first side (20) of the volume element (10) and by the other outer chamber (14) on a second side (22) of the volume element (10) facing away from the first side (20) at least in certain regions.
Volume element (10) according to any one of the preceding claims,
- characterized in that
- the outer chamber (14) has a volume fillable with the granular material, which is completely filled with the granular material.
Volume element (10) according to any one of the preceding claims,
- characterized in that
- the flexible material is substantially inelastic.
Volume element (10) according to any one of the preceding claims,
- characterized in that
- the outer chamber (14) is partially bordered by the at least substantially flexible material also at least partially bordering the inner chamber (12).
Volume element (10) according to any one of the preceding claims,
- characterized in that
- the volume element (10) is formed as a water sports equipment, in particular as a surfboard, floating island, airbed or the like.
