Definitions

  • This invention generally relates to sport pants with an externally located chamois, whereby the chamois comprises at least two layers, whereby the chamois is separated from the body by a protective layer.
  • the sport pants are designed with specialised cut-outs, both for male and female cyclists.
  • the chamois is preferably located near the crotch and buttocks region, and is designed in a way that it conforms the anatomical figure of the athlete, i.e. being able to fit the buttocks to e.g. a saddle in a comfortable manner, thereby reducing the chafing of the body and increasing the adhesion of the body to the saddle. Furthermore, moisture is transported towards the most outer foam-like member, comprising EVAPOR foam which is super breathable, vaporises the moisture and optimizes ventilation.
  • cycling pants comprising an inner pad in the crotch and buttocks region, also known as the chamois.
  • the main goals of the chamois of cycling pants are to fit the buttocks to the saddle in a comfortable manner, thereby reducing the chafing of the body, and to absorb moisture generated during sports practice.
  • Patent US4805243 describes synthetic foam pads
  • Patent IT1235265A uses a flat, shaped element in gel polymer.
  • U.S. Patent 4961233 provides a two-layer, one-piece, heat-formed, and seamless chamois that includes an inner liner imparting chaffing abrasion resistance and made of a synthetic leather-like material, and an outer synthetic fleece member that is compressible imparting cushioning.
  • the inner liner and the synthetic fleece are adhesive bonded.
  • U.S. Patent 5271101 provides cycling shorts that include a padded, three-layer, seat liner having a plurality of embossed break lines specifically positioned such that the liner conforms to the anatomical profile of a cyclist who is positioned in a riding position on a bicycle.
  • the liner is stitched or laminated to a body portion of the cycling pants.
  • the embossed break lines are formed without using stitching or sewn seams by heat moulding the seat liner in a flat position.
  • U.S. Patent 4945571 provides bicycling shorts having a liquid-filled cushion for cushioning the rider thighs and buttocks, the cushion having a plurality of layers of material to facilitate perspiration wickage.
  • the liquid cushions include overlying layers of a polyurethane material and water, non-freezable silicon or glycerin or mixtures thereof, oils or other slippery material.
  • WO2003037059 describes a chamois comprising a first cloth-like member of synthetic leather and a second cloth-like member of non-woven interfacing or a polyester-like batting.
  • US6817037 describes a pair of stretchable athletic pants comprising one or more panels attached together by one or more seams to form the pants in which at least one of the seams comprises an overlapping bonded seam.
  • US2005066423 provides cycling shorts comprising a layered chamois wherein the chamois comprises: a top layer suitable for accepting graphics and providing breath-ability; a cushion layer for providing comfort for a cyclist; and a bottom layer for providing a mate to the top layer so as to enclose the second layer.
  • US7707659 provides a multi-layer pad for bicycling shorts, comprising two distinct layers with a continuous foam layer located between the first cloth layer and the second cloth layer and contacting the first cloth layer and the second cloth layer.
  • chamois and paddings are located inside the pants.
  • DE102008034496 also has a small area located outside the cycling pants, as it provides cycling shorts with a back layer which has an internal and external surface.
  • WO2002024013 describes a seating element for a pair cyclist pants, whereby only the adhesive coating is located on the outside.
  • our invention describes a chamois which is fully located on the exterior side of the sport pants, making it unique among its kind.
  • the present invention describes sport pants with an externally located chamois.
  • the chamois is located onto the sport pants, preferably near the crotch and buttocks region.
  • the sport pants are preferably made of an elastic material such as Lycra, Lycra Polyester, Sport Lycra, Spandex, Elastane, polyester-polyurethane copolymer and can be used in different sports.
  • the externally located chamois comprises at least two different layers, in a preferred embodiment three layers, each layer consisting of a different foam with a different density.
  • foams are made of polyurethane and density lies in a range of 20-120kg/m 3 .
  • the externally located chamois is separated from the body by a protective layer.
  • This layer made of microfibers and with an antibacterial coating, transfers the moisture towards the chamois and protects the skin from friction and inflammation.
  • the inner foam-like member is located closest to the protective layer and has a top and bottom surface, in which the bottom surface is oriented towards the user (i.e. protective layer) and the top surface is oriented away from the user (e.g. towards the saddle), being formed in a shape that provides an enlarged area covering the complete contact zone of the user with the seating area (e.g. saddle). Furthermore, in a preferred embodiment the inner foam-like member has a wide rear part and a narrow front part.
  • the outer foam-like member is located most far away from the body (i.e. protective layer) and has a top and bottom surface in which the bottom surface is oriented towards the user and the top surface is oriented away from the user (e.g. towards the saddle); located on the top surface of the inner foam-like member thereby covering a smaller area than the inner foam-like member.
  • the outer foam-like member is made of reticulated EVAPOR foam, a 3D webbing that reacts differently to vibration and compression and that will rubberize upon impact, thereby creating a shock absorbing layer.
  • an intermediate foam-like member is located between the inner and outer foam-like members.
  • the intermediate foam-like member has a top and bottom surface in which the bottom surface is oriented towards the user and the top surface is oriented away from the user (e.g. towards the saddle); located on the top surface of the inner foam-like member thereby covering a smaller area than the inner foam-like member but a larger area than the outer foam-like member.
  • the intermediate foam-like member has a wide rear part and a narrow front part.
  • the different foam-like members comprise certain cut-outs, which are generally gender specific cut-outs, increasing the comfort based on the anatomical differences between males and females.
  • the main problem for the athlete is the fact that during races or training the crotch and buttocks are subjected to unceasing stresses, since such part of the body is in continuous contact with the seating area (e.g. saddle) and thus is subject to shocks and vibrations of different kinds. Accordingly, localized reddening can be acquired which can degenerate into cuts or blisters which make it difficult if not impossible to practice the sport.
  • Partial or full relief can be obtained by the placement of one or more inner pads in the crotch and buttocks region, also known as the chamois.
  • the chamois increases the comfort level of the athlete, thereby reducing the chafing of the body. Furthermore, moisture is absorbed by the chamois.
  • the present invention describes sport pants with an externally located chamois, preferably near the crotch and buttocks region.
  • the sport pants are preferably made of an elastic material such as Lycra, Lycra Polyester, Sport Lycra, Spandex, Elastane, polyester-polyurethane copolymer and can be used in different sports.
  • the externally located chamois comprises at least two different layers, in a preferred embodiment three layers, each layer consisting of a different foam with a different density ( figure 1 ).
  • foams are made of polyurethane and density lies in a range of 20-150kg/m 3 .
  • the density of the different layers is the same.
  • the density of the layers is different.
  • the density increases away from the user.
  • the density of the inner foam like member is in the range of 20-120kg/m 3
  • the density of the outer foam like member is in the range of 60-150kg/m 3 .
  • the density of the inner foam like member is in the range of 20-80kg/m 3
  • the density of the intermediate foam like member is in the range of 40-100kg/m 3
  • the density of the outer foam like member is in the range of 70-150kg/m 3
  • the density of the inner foam like member is in the range of 20-40kg/m 3
  • the density of the intermediate foam like member is in the range of 40-70kg/m 3
  • the density of the outer foam like member is in the range of 70-130kg/m 3 .
  • the combination of these foam-like members creates a blend of performance that is 1/3 of the mass and thickness of a regular high density perforated foam.
  • the different foam-like members comprise certain cut-outs ( figure 2 and 6 ), thereby delivering support to specific areas and/or preventing pressure in certain areas.
  • these cut-outs are gender-specific cut-outs, increasing the comfort based on the anatomical differences between males and females.
  • the externally located chamois is separated from the body by a protective layer.
  • This layer made of microfibers and with an antibacterial coating, transfers the moisture towards the chamois and protects the skin from friction and inflammation.
  • the protective layer is the primary connection site (by bonding or stitching) with the rest of the outfit.
  • the inner foam-like member is located closest to the protective layer and has a top and bottom surface, in which the bottom surface is oriented towards the user (i.e. protective layer) and the top surface is oriented away from the user (e.g. towards the saddle), being formed in a shape that provides an enlarged area covering the complete contact zone of the user with the seating area (e.g. saddle). Furthermore, in one embodiment the inner foam-like member has a wide rear part and a narrow front part. The inner foam-like member provides a thickness and density to support certain areas, thereby transporting the evaporated moisture generated during sports practice.
  • the inner foam-like member has a density in the range of 20-120 kg/m 3 ; in particular in the range of 20-80 kg/m 3 ; more in particular in the range of 20-40 kg/m 3 ; even more in particular a density of about 20 kg/m 3 .
  • the water vapor permeability of the foam-like members is greater than 1250 g/m 2 /24h.
  • the water vapor permeability of the foam-like members of the chamois is measured at 37.8°C using the ASTM-E96-66 standard.
  • the water vapor permeability of the foam-like members is greater than 3000 g/m 2 /24h, more particularly greater than 5000 g/m 2 /24h and most particularly the water vapor permeability of the foam-like members is greater than 10 000 g/m 2 /24h.
  • the outer foam-like member is located most far away from the body (i.e. protective layer) and has a top and bottom surface in which the bottom surface is oriented towards the user and the top surface is oriented away from the user (e.g. towards the saddle); located on the top surface of the inner foam-like member thereby covering a smaller area than the inner foam-like member.
  • each distinct area has a wide rear part and a narrow front part.
  • the outer foam-like member is made of reticulated polyurethane foam having a density in the range of 60-150 kg/m 3 and a porosity in the range of 10-90 Pores Per Inch (PPI); in particular a reticulated polyurethane foam having a density in the range of 70-150 kg/m 3 and a porosity in the range of 40-90 Pores Per Inch (PPI); more in particular a reticulated polyurethane foam having a density in the range of 70-130 kg/m 3 and a porosity in the range of 70-90 Pores Per Inch (PPI); even more in particular a reticulated foam having a density of about 70-90 kg/m 3 , herein also referred to as EVAPOR foam, a 3D webbing that reacts differently to vibration and compression and that will rubberize upon impact, thereby creating a shock absorbing layer.
  • PPI Pores Per Inch
  • the 3D webbing material creates high friction on the seating area (e.g. saddle), causing a more stable and supportive ride.
  • the seating area e.g. saddle
  • EVAPOR in his origin is a very rigid and rather hard material, when used as outer foam-like member at least one further foam-like member (inner) and preferably two further foam-like members (inner and intermediate) with a lower density have to be present.
  • EVAPOR foam is super breathable, vaporises the moisture and optimizes the ventilation of the sport pants.
  • an intermediate foam-like member is located between the inner and outer foam-like members.
  • the intermediate foam-like member has a top and bottom surface in which the bottom surface is oriented towards the user and the top surface is oriented away from the user (e.g. towards the saddle); located on the top surface of the inner foam-like member thereby covering a smaller area than the inner foam-like member but a larger area than the outer foam-like member.
  • the intermediate foam-like member has a wide rear part and a narrow front part.
  • the intermediate foam-like member provides a thickness and density to support certain areas, thereby transporting the evaporated moisture generated during sports practice towards the outer foam-like member.
  • the intermediate foam-like member has a density in the range of 20-120 kg/m 3 ; in particular in the range of 40-100 kg/m 3 ; more in particular in the range of 40-70 kg/m 3 ; even more in particular a density of about 40 kg/m 3 .
