Abstract
A cavity floor that includes a profiled sheet material. The sheet material has support feet that are substantially rigid. The surface of the sheet material extending between the support feet is substantially flexible. The thickness of the sheet material and the mutual spacing of the support feet are selected so that the sheet material is sufficiently rigid to support a person and sufficiently flexible to adapt to an uneven floor surface. The deformable surface enables automatic vertical adjustment of the support feet relative to one another when under load.
Claims18
A cavity floor comprising:
- a profiled foil having a thickness and comprising a sheet material provided with formed out parts defining substantially rigid portions and substantially flexible portions, the substantially rigid portions forming support feet that are arranged at mutual distances and the substantially flexible portions defining horizontal upper areas between the support feet, each support foot having a height, an end surface defining a peripheral circle and an open end defining an inner circle,
- said horizontal upper areas constituting deformation areas for automatic vertical adjustment of the support feet relative to one another when under load and said support feet comprising ribs that extend up to the deformation areas, and
- a lime floor layer that covers the support feet and provides a flat floor surface over the foil, characterized in that
- said support feet are provided with a lateral surface having a height and being free of horizontal kink lines;
- the ribs extend over the whole height of the lateral surface;
- the thickness of the foil and the mutual distances for the support feet being selected so that the foil is sufficiently rigid to support a person standing on the foil and sufficiently flexible to adapt to an uneven floor surface and the peripheral circle at the end surface of each support foot and the inner circle at the open end of said support foot both lie on a conical lateral surface with a maximum top angle of 50.degree..
A cavity floor comprising:
- a profiled sheet material having a thickness and defining substantially rigid portions and substantially flexible portions, the substantially rigid portions including a plurality of mutually spaced support feet and the substantially flexible portions including a resilient deformable surface extending between the support feet,
- at least one of the support feet having a bottom end defining a peripheral circle, a top end substantially adjacent the deformable surface and defining an inner circle, and a lateral surface substantially extending from the bottom end to the top end,
- a plurality of ribs substantially extending along the lateral surface from the bottom end to the top end,
- the peripheral circle and the inner circle mutually defining a conical lateral surface having a maximum angle of approximately 50.degree.,
- the thickness of the sheet material and the mutual spacing of the support feet being selected so that the sheet material is sufficiently rigid to support a person standing on the sheet material and sufficiently flexible to adapt to an uneven floor surface,
- whereby the support feet are capable of bearing a walking person and the deformable surface enables automatic vertical adjustment of the support feet relative to one another when under load.
