Definitions

  • the present invention concerns the field of impact absorbing units, particularly for use in the construction or building trade in which health and safety requirements dictate that exposure to uncushioned falls of greater than 2 metres or so must be prevented.
  • UK Patent GB 2367877 discloses an impact absorbing unit which has a generally rectilinear configuration in the form of an elongate block which has four long surfaces and two short end faces.
  • the blocks are formed from sewn panels of flexible web material. These panels form a rectilinear envelope which is filled with flexible filler material such as polystyrene granules.
  • These impact units provide a cushioning and deceleration effect which limits injury to a person falling onto a floor surface covered by these units.
  • a floor surface may be covered with a coterminous and coherent plurality of the units, effectively forming a false cushioned floor.
  • a problem with the known impact absorbing units is the cost of manufacture involved in attaching seams of several panels to form each unit.
  • the units are also subject to wear at the seams due to the rough manner in which they are handled in the building trade.
  • the seams are particularly vulnerable as they are sewn and therefore tend to detach.
  • laying out the units must be done in a methodical manner as replacement or insertion of single units in a pre-laid plurality is difficult because of the tight tolerances conferred by the rectilinear configuration.
  • an impact-absorbing safety unit comprising a flexible web envelope containing resilient impact absorbing material, which envelope is configured to adopt an elongate and generally cylindrical shape on filling with said resilient material.
  • the units are intended to be placed side by side over floor surfaces, so as to provide protection against falling for workmen or builders working at height.
  • the envelope web may be a heavy duty plastics film, a woven material or a felt.
  • the web is made from heavy duty woven plastics material, such as polypropylene. Other materials or heavy duty textiles may be employed.
  • the polypropylene has a density of approximately 200g/m 2 .
  • the cylindrical shape makes the units easy to lay down and to pick-up even when juxtaposed other neighbouring units. Furthermore, when the units are packed together they tend to deform locally so as to form a flat vertical or side contact surface, whilst maintaining curved edges which reduce exposure to wear and tear. Thus they are capable of covering a floor surface in a reasonably uniform and continuous manner without leaving gaps at the interfaces between units, and without losing useful cushioning in the region of the interface. Furthermore, a further layer of units stacked over the first is particularly stable as it is may be accommodated in the slight troughs formed at the interface between adjacent underlying units.
  • the cylindrical unit upon impact from a falling object, the cylindrical unit is squashed and deforms to take up a flatter configuration.
  • the falling object initially impacts against a slightly convex surface.
  • the unit Upon impact by the falling object the unit forms a substantially horizontal flat surface.
  • This deformation of the unit upon impact increases the time taken for the falling object to be fully decelerated.
  • the falling object experiences lower g-forces than it would falling onto a rectilinear impact absorbing unit. In the case of a falling person, this obviously reduces the chance or severity of any injuries occurring.
  • Said envelope may be formed from a single web panel having a cylindrical sleeve configuration.
  • Said web panel may be formed from a sheet of web material, said web having opposing long sides, which long sides are joined to form the cylindrical sleeve configuration.
  • the use of a single panel and a single seam considerably simplifies manufacture and reduces costs as compared to a rectilinear unit having multiple seams or welds.
  • the cylindrical sleeve could be formed without a seam. This is possible when using a tubular sleeve of material.
  • the impact absorbing material may be a particulate expanded foam polymer material, such as polystyrene fillers, or closed cell foam such as polyethylene.
  • the filler may be provided in one or more loosely packed bags, which bags are placed inside the web envelope before closure of the end portions.
  • the absorbing particulate material in each unit may be held in two elongate bags.
  • the absorbing particulate material may comprise two or more types of material.
  • the different types of material may be separated within the unit. Such separation could involve holding the different types of material in separate bags within the unit.
  • the unit may comprise a central bag containing polystyrene and two end bags containing polyethylene.
  • the different particulate material may be separated by the use of flaps inside the unit.
  • the unit may comprise a central portion containing polystyrene and two end portions containing polyethylene and the portions may be separated by flaps inside the unit.
  • Polyethylene is heavier than polystyrene and retains its shape better than polystyrene. However, it is more expensive than polystyrene.
  • polyethylene only at the ends of the units reduces the cost from using polyethylene throughout the unit. However, it helps the units to retain their shape after impact. This means the ends of the units do not become squashed and deformed after use. This is particularly advantageous as the ends of the units generally provide a particular weak area where two units meet. Furthermore, having polyethylene at the ends of units allows the end of the units to deform to match the shape of an adjacent unit. Hence, the units can fit closer together.
  • one type of material may be contained in an inner cylindrical bag extending the length of the unit and surrounded by an outer layer of another type of material.
  • the inner cylindrical bag may be held in a central location of the unit by the use of hanging loops connecting the inner cylindrical bag to the inside of the unit.
  • the inner cylindrical bag may contain polyethylene and the outer layer may comprise polystyrene.
  • the bags may be made from a thin, rupturable polyethylene material.
  • the loosely packed bags may be placed inside the web envelope and the impact absorbing material emptied from the bags. The empty bags could then be removed before closure of the end portions of the web envelope.
  • the bags may be left open inside the web envelope to allow the impact absorbing material to freely move within the closed web envelope.
  • the web envelope may be filled directly with impact absorbing material for example, directly from a storage silo.
  • the density of the particulate foam is preferably between 4.0 to 5.2 Kg per cubic metre.
  • opposite end portions of the cylindrical sleeve are gathered and fastened to form closures at each end.
  • the gathered end portions may be fastened by crimping or any suitable securing means, such as use of a draw string or cord, metal or plastic clamps, gluing etc.
  • the gathered end portions are preferably tucked inwardly back into the envelope so as to provide a generally flat end face at each end of the envelope and reduce potential wear and damage.
  • the use of a drawstring to fasten the ends of the units is especially advantageous.
  • the drawstring may be threaded through hems at the edges of the cylindrical sleeves.
  • a sleeve with a drawstring pre-threaded through it may be stitched around each edge of the cylindrical sleeve.
  • the drawstring is pulled taught the edges of the cylindrical sleeve are gathered towards each other at the ends of the units.
  • the drawstring arrangement does not leave any excess material at the ends of the units that needs to be tucked back into the envelope.
  • the drawstring is contained within a sleeve of material.
  • the sleeve may have a width of approximately 6cm.
  • This drawstring sleeve material may be a heavy duty plastics film, a woven material or a felt. It may be made from a heavy duty woven plastics material, such as polypropylene. It may be the same material as the envelope web. Most preferably, however, it is made from polypropylene with a density of approximately 100 g/m 2 . This density is lower than that preferably used for the envelope web. The lower density material is softer and more flexible and allows the drawstring to be pulled tighter without the sleeve material bunching. Hence, the ends of cylindrical sleeves can be gathered closer together to leave a smaller hole at the ends of the units.
  • the drawstring may comprise tape, string or a plastic tie.
  • the plastic tie may preferably contain a ratchet mechanism (similar to that of a cable tie) to lock it in position once it has been pulled taught and the edges of the sleeve have been sufficiently gathered.
  • the ratchet mechanism is capable of being unlocked.
  • the drawstring may be held taught by one or more lugs.
  • the lugs may comprise a hole through which the drawstring passes.
  • a biased stopping member may be provided on one side of the hole. It may be biased in such a way so as to act to close the hole and hold the drawstring in place between the stopping member and a corresponding surface on the other side of the hole.
  • the biasing force may be provided by a spring.
  • the units may further comprise one or two inner flaps. These inner flaps are placed inside the web envelope across one or each end of the unit.
  • the inner flaps prevent any impact absorbing material escaping from the web envelopes. It is especially advantageous to use inner flaps when a drawstring arrangement is used to gather the edges of the cylindrical sleeves.
  • the inner flaps prevent impact absorbing material escaping through the hole formed by the gathered material.
  • the hole could be approximately 10 mm in diameter.
  • the inner flaps could be circular. They could be of a diameter greater than the diameter of the hole formed by the gathered material.
  • the inner flaps could alternatively be rectangular.
  • the inner flaps may be attached to the inner surface of the web envelope (for example by stitching along one part of the circumference of the flap) or may be loose pieces of material placed inside the web envelope.
  • the inner flaps are made from polypropylene with a density of approximately 100 g/m 2 .
  • the opposite end portions of the sleeve may each be provided with an overlap flap, which flap is attached at one end to an end region of the sleeve and positioned so as to be capable of being drawn across to overlap and cover the end tucks of the gathered and fastened closures.
  • a free end region of each of the overlap flaps may be provided with fastening means for securing the flaps in their overlapped position.
  • the fastening means may comprise a toggle and loop pairing. However suitable fasteners may be used, such as VelcroTM type or plastic rivets, clips or gluing/welding.
  • the flaps are fastened with a combination of VelcroTM strips and straps with buckles, comprising male and female portions.
  • the buckles are such that they require a prising action or similar to be released. This ensures the buckles are not accidentally released during use.
  • the overlap flaps are made from the same material as the envelope web. Most preferably, or alternatively, the flaps are made from polypropylene with an approximate density of 200 g/m 2 .
  • the overlap flaps have a width sufficient to "close off the ends of the units so that any gathered end portions are contained and/or holes in the ends of the unit are covered.
  • the overlap flaps may have a width of approximately 40 cm.
  • the overlap flaps have a length sufficient to extend over the length of an end of the unit from one side of the unit to the other side.
  • the overlap flaps may have a length of approximately 80 cm.
  • An exterior surface of the envelope is provided with a plurality of fasteners, each of which is to be engaged with a corresponding fastener of further units which may be juxtaposed the first unit.

  • the fasteners are preferably positioned so as to allow the units to be positioned side-by-side and coterminous with each other.
  • fasteners may be positioned so as to allow a plurality of units to be fastened side- by-side but non-coterminous so that one unit may be fastened on one side to respective end regions of two units arranged end on end and adjacent the first unit, in a brick work fashion.
  • End fasteners may be positioned so as to permit fastening of adjacent units end-on-end, or in a T-configuration in which an end of one unit is fastened to a side of another unit.
  • the end and side fasteners may be positioned to permit fastening of a plurality of units end-on to the side of another unit.
  • the fasteners may be such that three units can be fastened end-on to the side of another unit. When the units are so fastened, the sides of the outermost end-on units may be coterminous with the ends of the other unit.
