In one embodiment the invention provides an impact-absorbing unit comprising an outer wear-resistant casing (10) and one or a plurality of inner stress resistant envelopes (20) containing impact absorbing material. The outer envelope is provided with a plurality of interconnection means (65, 70) on at least one surface thereof, whereby a plurality of such units can be connected together in a closely adjacent relationship to define a substantially continuous surface. In another embodimentthe compressible elements are directly enclosed within the casing (10).In another embodiment the loose fill of compressible elements is replaced by at least one open cell foam element and valve means are provided for evacuating air from the foam, whereby to compress the foam and allow subsequent expansion thereof by exposure to ambient air pressure.
An impact-absorbing unit comprising an outer wear-resistant casing and one or a plurality of inner stress resistant envelopes containing impact absorbing material, the outer envelope being provided with interconnection means associated with at least one surface thereof whereby a plurality of such units can be connected together in a closely adjacent relationship to define a substantially continuous surface.
An impact-absorbing unit as claimed in any preceding claim, in which the said interconnection means comprise a clasp or the like
An impact-absorbing unit as claimed in any preceding claim, in which the said interconnection means are arranged to allow interconnection of adjacent upper and lower surfaces of respective units whereby to allow stacking of units to increase the absorbent capacity of the said substantially continuous surface.
An impact-absorbing unit as claimed in any preceding claim, further comprising a handle portion.
An impact-absorbing unit as claimed in any preceding claim, in which the fill density of impact-absorbing material is in the region of 1.85 to 1.90 kg per 0.425 cubic metres of inner envelope.
An impact-absorbing unit comprising an outer wear-resistant casing, a closed inner stress resistant envelope containing a plurality of compressible elements loosely enclosed within it, the said outer wear-resistant casing comprising a plurality of substantially planar flexible panels secured together in such a way as to maintain an external form having at least one substantially flat surface to allow a plurality of such units to be placed adjacent one another with the said at least one surfaces of each unit lying substantially in a common plane whereby to define an overall surface for receiving falling objects.
An impact-absorbing unit comprising an outer wear-resistant casing containing a plurality of compressible elements loosely enclosed within it, the said outer wear-resistant casing comprising a plurality of substantially planar flexible panels secured together in such a way as to maintain an external form having at least one substantially flat surface to allow a plurality of such units to be placed adjacent one another with the said at least one surfaces of each unit lying substantially in a common plane whereby to define an overall surface for receiving falling objects.
An impact-absorbing unit comprising an outer wear-resistant casing, at least one closed inner stress-resistant air-tight envelope containing at least one compressible foam element within the said envelope, and valve means for evacuating air from the said envelope compressing the said foam, the said outer wear-resistant casing comprising a plurality of substantially planar flexible panels secured together in such a way as to maintain an external form having at least one substantially flat surface, when the said foam element is expanded, to allow a plurality of such units to be placed adjacent one another with the said at least one surfaces of each unit lying substantially in a common plane whereby to define an overall surface for receiving falling objects.
A protective surface comprising a plurality of units according to any preceding claim.
