Definitions

  • This invention relates to protective footwear.
  • This invention has particular but not exclusive application to workboots for use in firefighting and chemical spill applications, and for illustrative purposes reference will be made to such application. However, it is to be understood that this invention could be used in other applications, such as general purpose workboots and protective footwear.
  • boot production generally revolves around the generation of piecework components of the boot which are then formed up and assembled on a traditional last or bootmaker's anvil, to be then stitched together by skilled machinists.
  • the traditional techniques accordingly suffer from the disadvantages of requiring a high level of machinist skill and time.
  • heel guards and the like must be inserted in the workboot, these are generally incorporated as insert pieces interposed between layers of the traditional boot construction. Accordingly, such protective footwear in generally heavy out of all proportion to the degree of protection afforded by the insert.
  • US-A-3248810 discloses a "safety" shoe which is manufactured by injection moulding.
  • Protective inserts are located on a last by means of studs and than material is injected around openings to fill free space left between the protective inserts and the mould.
  • GB-A-863944 discloses a boot or shoe which incorporates a metal stiffener or toe guard within material forming the toe of the boot or shoe and also a metal sole plate bonded between upper and lower layers of rubber or rubber-like material in the sole of the boot or shoe.
  • DE-A-2136522 discloses a protective boot which incorporates a protective heel, sole and toe portion all of which are separate. These portions are affixed and moulded into a sole portion to hold them together.
  • the present invention provides a protective footwear assembly having an outer sole, a footwear upper affixed to or integral with the outer sole and a protective insert member, the outer sole and the footwear upper arranged to encapsulate the protective insert member to form a protective footwear assembly, characterised in that the protective insert member comprises a flexible inner sole portion, a heel counter portion a toes cap portion, the inner sole portion being integrally formed with at least one of the heel counter portion and toes cap portion and the other one portion being affixed to the inner sole portion, or both the heel counter and toes cap portions being affixed to the inner sole portion, and an arch protector portion connected to the inner sole portion, such as to form a unitary capsule to protect the sole, heel and toes of a foot.
  • the protective insert member comprises a flexible inner sole portion, a heel counter portion a toes cap portion, the inner sole portion being integrally formed with at least one of the heel counter portion and toes cap portion and the other one portion being affixed to the inner sole portion,
  • the sole portion and boot upper portion may each take any form consistent with the function of providing a suitable exterior of a protective work boot.
  • the precise form of the asembly of upper and sole will at least in part be dictated by the type of protection to be afforded.
  • the upper and sole may be generally or specifically constructed or materials proof against the expected contaminants.
  • the protective insert member may take any form consistent with the function of providing some protection to the sole, heel, arch and toes of a wearer of the boot.
  • the protective insert member comprises a moulded polymeric sole portion having integrally formed therewith a heel counter portion, although it is also envisaged that the heel counter portion may be affixed to the sole portion by any suitable means such as interlocking complementary joining means.
  • the heel counter portion is of relatively rigid form compared with the sole portion such that the sole portion retains some flexibility whilst providing penetration resistance, thus promoting a natural and comfortable walking gait, whilst the heel counter provides maximum protection against impact and crushing.
  • the protective insert member further includes a toe cap, and an arch protector.
  • the toe cap and arch protector may be relatively stiff compared to the sole portion in order to maximise impact resistance with a minimum of unnecessary bulk.
  • the toe cap and/or arch protector may take any form consistent with the function of providing protection to the toe region and/or the arch region of a wearer's foot.
  • the toe cap and/or arch protector are moulded integrally with the sole and heel counter to provide an integral, full function protective insert member, providing for foot flexibility as well as penetration resistance and protection against side or rear impacts.
  • the toe cap and arch protector may be affixed to the sole and heel counter moulding or assembly by any suitable means.
  • the shapes of the arch protector and toe cap are selected so objects tend to roll off, the shapes of one or more of said arch protector portion and toe cap portion being preferably moulded such that their outer surfaces run away from their respective top centres. It has been found that this arrangement of the toe cap and arch protector substantially overcomes the disadvantages in this regard of standard boots, which generally only have toe caps.
  • the toe caps used by the prior art are generally flat and often angled backwards due to the spring of the shoe, providing no protection for the arch.
  • the sole portion of the protective insert provides protection from penetration through the sole and heel and preferably provides, in conjunction with the toe cap and arch protector if desired, a protective capsule for the foot as a whole from objects impacting on the sides and top.
  • a protective capsule for the foot may protect the foot against injury.
  • the area of the sole portion between the arch protector and the heel counter is arched to provide desirable support for the foot over the full width of the arch to assist with long term wearer comfort and support.
  • the heel counter portion is angled inward towards the top, as does the heel of the foot, to provide better support and stability.
  • the sole portion of the protective insert is preferably provided with a concave depression in the heel area to accept the heel in its natural shape.
  • the relative shapes and hence the distance between the toe cap and arch protector are selected to allow the maximum amount of foot flexing at the ball of the foot whilst maintaining the minimum distance at the top between the two consistent with allowing for the maximum extension of the foot.
  • heel counter portion is an integral part of protective insert it is preferred that the relative stiffnesses of the heel counter portion and sole portion are selected such that sideways forces are not transferred to the counter, a common defect of the prior art which leads to less foot support and tends to cause the counter to degenerate.
  • insert member be fully integral to form a protective foot capsule since this reduces the number of components in the manufacturing process.
  • the toe cap portion and arch protector portion of the protective insert be relatively rigid compared with the sole portion to provide resistance to crushing and impact whilst permitting flexing of the foot.
  • the relatively stiff outer edges of the toe cap portion and arch protector portion may meet the more flexible sole portion, restricting the sole portion from flexing during impact in the region of the toe cap portion and arch protector portion, whilst maintaining the aforementioned flexibility between the relatively rigid portions.
  • the arch protector shape is selected to provide maximum width of the arch protector portion for as much of the height of the arch protector portion as possible to facilitate the free movement in and out of the boot, the widest part of the foot being generally forward of the protector with the angle of entry of the foot being generally higher during entry and exit than during wearing the boot.
  • the shape and configuration of the toe cap portion is preferably selected to yield a toe cap having the shape of a portion of an egg and is both relatively high off the foot at the rear of the toe cap and has no flat surfaces.
  • the height of the preferred toe cap not only allows for objects to roll off the foot but enables the foot to bend fully without the upper rubbing against the top of the foot.
  • the "egg" shape of the preferred toe cap greatly increases its ability to resist impacts and provides a more protective capsule for the toes than toe caps of the prior art.
  • the inside of the boot in the region of the counter portion is padded with a suitable padding material such as a non-flammable cellular elastomer.
  • a suitable padding material such as a non-flammable cellular elastomer.
  • the elastomer is selected from those having a shore hardness of about 25 to provide an acceptable compromise between comfort and strength.
  • Such padding fulfills not only the function of providing comfort and supportive feel for the heel, but also allows for heel abnormalities to be comfortably accommodated.
  • the foot contact area within the protective insert member may also be lined with a comfort promoting material.
  • the boot includes an internal lining sock of fine leather or other suitable material, and the space between the internal lining sock and the protective insert member is preferably padded with a non flammable polymeric foam such as an ester foam.
  • the foam is selected to have a density suitable for providing a firm, comfortable feel without putting any pressure on any foot abnormalities, such as bunions, spurs and the like.
  • Boots manufactured in accordance with the present invention may be provided with a footbed, with it being preferred to use a footbed of a similar type to that used in the mid soling of better quality sporting footwear.
  • the footbed is of a substantially non flammable closed cell foam polymeric material, providing a comfortable and supportive base for the foot.
  • the depth of the sock liner together with its shape may be selected for supportive quality and to provide for orthotic adjustments where necessary.
  • the protective footwear in accordance with the present invention may be closed by any suitable means.
  • the protective footwear is closed by means of self adjusting, non flammable elastomer such as that having similar qualities to the elastic in elastic sided boots.
  • the protective footwear may also be provided with a quick close/release attachment, preferably of the type useful to surround the ankle and the top of the protective footwear.
  • the elastomeric adjustment allows for comfort of fit, the elasticity thereof also providing support whilst not overly reducing movement of the foot.
  • protective footwear in accordance with the present invention are provided with ankle restraining means to provide ankle support whilst not totally eliminating for and aft movement of the foot, a movement which is important, particularly when driving.
  • the ankle support means also serves to help prevent the foot slamming against the toe cap, for example, when going down hill.
  • the ankle support means takes the form of a flexible strap member angled from the base of the achilles tendon, across the ankle and over the instep.
  • similar support is provided for the lower leg by means of a supporting closure at the top of the boot which may also serve the purpose of providing closure against the trouser leg of the wearer.
  • the outer sole portion of the protective footwear may take any suitable form, generally dictated by the use to which the footwear is put.
  • a particular type of outer sole is amenable for use in a wide variety of applications, such as fireman's boots for use in both chemical spill and firefighting applications.
  • firemen it has generally been necessary for firemen to maintain a plurality of specialized footwear for use in such diverse applications.
  • a fire boot may not have the chemical resistance of a specialised chemical-spill boot, this has generally occurred because the soling of the chemical boot was unsuitable for use in a fireboot and accordingly it was not worth making the fire boot chemical resistant.
  • the footwear sole portion includes
  • the flexible body of the boot sole may take any suitable form and is preferably of a fire and chemical resistant natural or synthetic resilient material.
  • the body member is an integral moulding of two parts, namely, a tough outer skin of heavy duty rubber providing abrasion and penetration resistance and an enclosed cellular layer allowing for considerable weight saving and improved shock absorption.
  • the body is of a wedge shape, rather than the conventional sole and heel moulding to provide more even support. It has been found that the use of the wedge shape provides for lift at the toes is similar to sporting footwear as opposed to the rather gumboot-like action of conventional protective footwear.
  • the body may be provided with an upper peripheral extension to facilitate bonding or other attachment to a boot upper as well as providing additional protection from aggressive chemicals and abrasion.
  • the upper peripheral extension is angled inward from the periphery of the sole and is provided with an internal ridge, allowing the sole to engage a protective insert such as that hereinbefore described.
  • the transverse depressions include a relatively large depression in the region of the instep of the sole, to provide enhanced ability to safely engage ladder rungs and the like.
  • the depressions towards the toe and heel of the sole from the instep depression may be identical or may vary, with it being preferred that the sole be provided with progressively smaller depressions towards the toe and heel, providing for a gradation of sole flexibility away from the instep.
  • a relatively large ridge between depressions in the region of the ball of the foot of the wearer, the ridge and adjacent depressions forming a concave portion on either side of the ball of the foot, provide for enhanced foot flexibility with the minimum of movement of the outer sole, and a preferably longer convex portion under the ball of the foot to provide additional support.
  • the ground engaging surface may be smooth or may be provided with a textured surface to improve the grip of the sole.
  • the ground engaging surface is provided with a textured surface comprising generally transverse ripples or creping, the textured surface providing grip in both traction and braking.
  • the wave shape of the sole and the small ripples are selected such that walking shock is dissipated along the sole rather than directly upwards to the foot.
  • the wave shape of the preferred soles also allows stones, caked mud and the like to be released from the sole due to the normal walking action causing the sole to flex, periodically opening out the depressions.
  • the ridges are also provided with a plurality of substantially longitudinal depressions cutting through the crests of the ridges between the transverse depressions, the wave shape, together with the longitudinal channels, allowing fluids to pass under the sole without around the sole and reduce the hydroplane effect.
