Definitions

  • the invention relates to socks or stockings, and especially to those destined for use by players of sports such as association football (soccer), rugby and hockey where the use of shin protectors is customary.
  • Sports socks are. of course, known in themselves. In many sports, such as football and hockey, shin protectors are won by the players to protect their shins from injury resulting from impact by balls, hockey sticks, or other players. As technology has entered into the sports arena over the years, the nature of the various elements of the games and associated equipment has evolved. Some of these changes will be discussed with reference to football as just one example.
  • football boots One such development is the nature of football boots.
  • football boots were robustly built, usually from leather, and provided a high degree of protection for the player's feet, not only against mechanical damage, but also from the wet conditions often encountered on a football pitch.
  • football boots have become much lighter items with the design emphasis being on technical features to aid ball control and grip: lightness is a key consideration, and waterproofing is often minimal.
  • lightsness is a key consideration, and waterproofing is often minimal.
  • players' feet often tend to get wet during play, leading to discomfort and a reduction in ball control.
  • FIG. 1 illustrates a typical modem shin protector, generally indicated by 1 , on the leg 2 of a user.
  • the shin protector often comprises a rigid curved plate 3 shaped to sit around the shin area of a user's leg 2.
  • the plate may typically be backed by a layer of compressible, impact-absorbing material located between the plate and the user ' s shin.
  • the shin protector extends from just above the ankle region 4 to just below the knee 5 of the user's leg 2.
  • Attached to the bottom of the plate is an elasticated portion 6 that encircles the user's ankle region. This portion may also be equipped with an elasticated foot strap 7 that passes below the user's foot 8.
  • the plate 3 may also be provided with a releasable elasticated calf strap 9 to encircle the user's calf, and secure the shin protector in place.
  • the invention provides a sock comprising sequentially: a foot portion. configured to cover, in use. a user's foot, toes and ankle region: a shin portion, configured to cover, in use. a user's shin and substantially all of a user ' s calf: and an elasticated cuff portion; and wherein the foot portion, only, is of a waterproof but breathable construction.
  • a shin protector can be accommodated within the sock whilst the waterproof foot portion provides protection to the user ' s foot region.
  • the inventors have found that it is more important to protect a player ' s feet from getting wet during play than other areas, as any moisture in this area tends to be trapped within the boot rather than being able to evaporate as might happen from e.g. the shin area.
  • the shin portion is elasticated and configured to accommodate, in use. a shin protector located on a user's shin.
  • the sock By using an elasticated shin portion, the sock will act to further secure the shin protector in position on a player ' s leg. in addition to the straps 7,9 that might be provided.
  • the foot portion is elasticated so as to conform generally, in use. to the shape of a user's foot region.
  • the effective elastic modulus of the foot portion is greater than that of the shin portion.
  • the foot portion By using an elasticated structure for the foot portion, creasing of the foot portion is avoided in use. thus preventing pressure points and ensuing damage to the foot.
  • the effective elastic modulus of the shin portion By tailoring the effective elastic modulus of the shin portion be less than that of the foot portion, the shin portion can readily expand to accommodate a shin protector without putting undue pressure on a user ' s calf.
  • the effective elastic modulus of the cuff portion is greater than that of the shin portion.
  • the shin portion at least, is provided with a water-repellent finish.
  • Figure 1 is a schematic perspective view of a sports shin protector on a user's leg
  • Figure 2 is a schematic diagram of a sock according to the present invention
  • Figure 3 is a cross-sectional view of a sock of the present invention
  • Figure 4 is a series of cross-sectional views of the waterproof, breathable portion of a sock of the present invention, showing one method of construction.
  • Figure 2 illustrates a sock according to the present invention comprising a foot portion 10, to cover a user's foot, toes and ankle region; a shin portion 11 to cover a user's shin and substantially all of a user's calf, and an elasticated cuff portion 12 to grip a user's leg, typically around a user's knee region.
  • the sock has a turned heel portion 13.
  • the foot portion 10 is constructed from a composite fabric that is waterproof, but breathable. Structures that provide this functionality are known in the art, e.g. in US Patent 5.244.716. A particularly preferred embodiment of a sock, and details of the construction of the waterproof, breathable, section will be described by reference to Figures 3 and 4.
  • Figure 3a shows a cross-section through a sock of the present invention, having a foot portion 10. a shin portion 1 L and a cuff portion 12.
  • the shin portion 11 in this figure is shown reduced in length, for clarity, and would in practice be long enough to cover, in use. a user ' s shin and substantially all of a user ' s calf.
  • the outer layer of the sock 14. that forms the cuff, shin and outer layer of the foot portion is constructed from a knitted fibre, such as woven acrylic. Knitting patterns and/or choice of fibres are selected to provide a differential effective elastic modulus between the three portions.
  • the effective elastic modulus of the material is. as is known in the art, the force required to stretch the fabric from its "at rest' * configuration.
  • the appropriate effective elastic modulus may be measured by determining the slope of the stress-strain relationship of aportion of the sock along a direction circumferential to an intended user's leg or foot, and for extensions within the substantially linear, initial portion of that relationship.
  • the effective elastic modulus may be varied by choice of knit/weave pattern or, e.g. by the inclusion of elastic fibres within the weave.
  • the elastic modulus of such fibres, their size, and the number of fibres used call all be employed to control the effective elastic modulus of the complete fabric.
  • the elasticity of the foot and shin portions. 10 and 1 1 respectively) of the outer layer 14 may have a broadly similar effective elastic modulus.
  • the effective elastic modulus of the foot section 10 is reduced, producing a close, but non-restrictive fit to a user ' s foot.
  • an inner layer 15 constructed from a knitted wool.
  • Other materials may be employed to form this inner layer, and the materials and kit, or weave, pattern is selected to create an elastic, stretchable fabric.
  • the inner layer may be made of a synthetic fibre such as that sold under the registered trade mark Coolmax, typically blended with a small amount of elastic material to produce the correct elasticity.
  • the inner layer 15 extends only within the foot portion 10. and terminates just above the ankle, in use. of a user.
  • Membranes of this type are known in themselves, such as the hydrophilic polyurethane membrane sold under the registered trade mark Porelle.
  • the three elements of outer 14, inner 15 and membrane 16 layers are bonded by an array of dots of heat-activated adhesive 17.
  • Figure 3b is a close-up cross- section of part of the foot portion 10 of the sock, and illustrates the configuration of the three layers. Methods of construction of such elastic, waterproof breathable composite materials are known in the art, but for clarity will be described by reference to Figure 4.
  • Figure 4 illustrates stages in production of the three-layer stretchable, waterproof and breathable fabric composite.
  • Figure 4a illustrates an outer woven layer 14. an inner woven layer 15, and the waterproof breathable membrane 16 with an array of heat- activatable adhesive dots 17 located on each side of the membrane 16.
  • the inner 15 and outer 14 layers are stretched to have the same approximate area as the membrane 16 which itself is considerably larger (by perhaps 2-3 times) than the required surface area of the finished article.
  • the three layers (14, 15, 16) are brought into close contact with each other, as illustrated in Figure 4b: this may readily be achieved by the use of a former, over which the three elements are placed.
  • the outer layer 14 may be stretched over a former, the membrane 16 then placed over the inner layer, and finally the inner (smaller) layer 15 stretched over the membrane 16. Then, the whole assembly is pressed together and heat is applied to activate the adhesive 17, which bonds the three layers together.
  • the composite may then be removed from the former, whereupon the effective elastic modulus of the inner and outer layers returns the composite to approximately the original unstretched size of the inner and outer layers, and causes the membrane 16 to adopt a ruched or puckered configuration as illustrated in Figure 4c.
  • a composite is formed that has the required waterproof breathable properties, whilst retaining the stretchablility of the inner and outer layers in the face of the relatively inelastic membrane 16.
  • the bonding of the three layers in the foot portion is particularly important in a sporting context.
  • the bonding ensures that there is no damage to the membrane as a result of the high impact activity of the players. More importantly, however, the bonding of the layers ensures that there is no slip between the three layers that might otherwise interfere with the control that a player needs to exercise over feet, boot and ball, and that requires a firm connection between the three.
  • the shin portion 11 is further treated with a water-repellent coating to shed any water coming into contact with the sock to prevent it wicking along the fabric and into the user's shoe, or onto the elasticated portion 6 of a shin protector 1 worn by a user.
  • a water-repellent coating are known in the art. often comprising a heat-activated fluorinated finish, known in the art as "DWR".
