Definitions

  • the present invention relates to a resilient sole cover which can be strapped onto the shoe of a wearer for purposes of providing a layer between the shoe and a floor where the layer can provide additional resilience and/or an anti- slip effect.
  • Anti-fatigue mats have been designed to provide effective shock attenuation to address this problem. These mats are made of various materials including rubber, vinyl, wood and carpeting materials. By alleviating pressure, it can help stimulate blood circulation and possibly reduce stress of the lower back, leg joints, and major muscle groups. The result is an improved workplace with fewer occupational health complaints.
  • One anti-fatigue mat is available from 3M which is formed of a layer of intermingled course strands of heat bondable flexible plastics or rubber material which fibers are bonded together at crossing points to form an interconnected mat.
  • One surface of the layer is relatively flat and the bonding effect is more pronounced with some of the strands clearly melted in the bonding process to form a tight surface while the other surface is looser and the strands less bonded together so that the strands are loose at the surface and stand out from the surface.

The mat is applied to the floor surface such as concrete with the tight surface in contact with the floor and the loose surface facing upwardly. This mat is resistant to wear and to damage from commercial use including material spills and thus is widely used.

  • the projections thus extend through respective holes and the planar web 54 sits between the top surface of the layer and the sole of the shoe.
  • the web is relatively thin and its thickness is absorbed into the resilience of the layer so that its presence is not appreciable by the wearer. The wearer therefore feels as if there are walking on the whole surface of the layer rather than merely on a series of projections which would be uncomfortable under the feet.
  • Each of the projections is moulded from the stiff plastics material but includes a metal insert pin 56 which is inserted into the mould along an axis of each projection so as to provide an additional rigid engagement element which engages the ground in an anti-slip action.
  • the top surface of each projection can thus be moulded into a recess or semi circle 57 which provides engagement with the ground provided by an outer ring 58 and the metal tip 59 of the metal pin 56 in the centre of the ring.
  • This arrangement provides effective gripping action on the ground with sufficient force obtained simply by depressing the projections of the layer which are resilient so as to reduce the force on the layer and increase the force on the stiffer projections of the anti-slip insert 50.
  • the insert 50 can be readily placed onto the layer when the shoe is removed from the layer and pushed through the holes to take its place. When required to be removed, one end of the insert can be grasped at the web 54 pulling the projections out of the holes and removing the insert from the layer so that the layer can be used again with the insert.
  • the insert depends upon the amount of slip on the ground so that in icy conditions where extra grip is required, the insert can be used. On hard surfaces such as oily or greasy concrete or other solid floor, the insert can be removed since it is of less value when the surface is rigid such as concrete.
  • the layer which is a strap on arrangement for attachment to the sole of the shoe of the wearer provides the possibility for the sole to be manufactured from a more resilient, less wear resistant material since the sole can be readily replaced in view of the fact that it is relatively cheap in comparison with complete shoes where the upper also must be replaced.
  • an improved anti-slip arrangement can be provided with the projections on the underside of the layer since they can be formed from a material which provides the maximum anti-slip ability without concern for the increased rate of wear which is therefore obtained.
  • the layer with the simple strapping arrangement can thus be readily discarded when the wear of the projections of the layer exceeds an acceptable limit.
  • Figure 7 is shown a further modified arrangement where the layer is indicated at 60 and the insert at 61.
  • the layer has a bottom surface which is defined by a plurality of evenly spaced cylindrical projections or nubs 62 which project from the bottom surface of the layer for engaging the ground.
  • the nubs thus can individually flex slightly and provide an outside edge which is circular and thus provides a whole series of edges in all directions which can bite into the ground to provide an anti-slip effect.
  • a number of the cylindrical nubs or projections are omitted to provide holes for receiving the projections of the insert which is of the construction shown in Figures 5 and 6.
