Definitions

  • the present invention relates to snowboard boot having an asymmetrical support member and in particular to a support member which provides flexibility to the boot in response to leaning in one direction but rigidity in response to leaning in an opposite leaning direction.
  • Snowboard boots are highly specialized footwear which provide specific foot and leg support for maneuvering a snowboard.
  • movement control such as steering and braking, are effected by leaning in specific directions such that the snowboard engages snow to guide the rider in a desired direction.
  • the snowboarding enthusiast in order to turn in a specific direction, the snowboarding enthusiast must lean in that direction so that the snowboard tilts in that direction.
  • a person riding a snowboard wears snowboard boots that are designed to be rigidly connected to the snowboard.
  • the front of the persons body is usually oriented at a ninety degree angle with respect to the front end of the snowboard with the boots similarly oriented and mounted on the snowboard.
  • a persons left side may be facing forward when mounted on the snowboard, In this orientation, the person must lean backward to effect a left hand turn and must lean forward-to effect a right hand turn.
  • Various other movements are likewise required for maneuvering the snowboard.
  • the requirements of the snowboard boots are such that when a snowboard rider leans in any given direction, the boots must transmit that leaning movement to the snowboard. Therefore, the snowboard boots must be rigid with respect to the leaning directions.
  • the inner side is defined as the left side of the right hand boot.
  • the inner side is also defined as the right side of the left boot.
  • the outer side is defined as the left side of the left boot and the right side of the right boot.
  • the respective inner and outer sides of a snowboard boot ideally should not have the same rigidity.
  • snowboarders have become aware that the inner side of the boot should be flexible such that the boot may accommodate a lean toward the inner side. Further, the ideal situation would be to have inner side be flexible at all times.
  • the outer side should be rigid in leaning toward the inner side and the outer side should be rigid when leaning toward the outer side.
  • Some snowboard boots provide an angled strap on the outer side of the boot which provides the inner and outer sides with rigidity when leaning against the length of the strap but do not provide the outer side with rigidity when leaning toward the inner side.
  • Such a snowboard boot is shown in EP-A-0 646 334.
  • One object of the invention is to provide an inner side of a snowboard boot with rigidity when leaning toward the outer side and flexibility when leaning toward the inner side.
  • an article of footwear includes a sole portion made of a sole forming material having a fastening mechanism incorporated therein.
  • An upper portion is adhered to the sole portion.
  • the upper portion is formed with an outer layer, a support member and an inner liner with the support member being layered between the outer layer and the inner liner.
  • the support member has an inner side and an outer side. The inner side corresponding to an inner ankle side, and the outer side corresponding to an outer ankle side. The inner side and the outer side is asymmetrical with respect to one another.
  • the support member further includes a strap portion that extends between a lower portion of the inner side and the upper portion of the inner side. The strap portion provides tensile force rigidity between the lower and upper portions of the inner side and flexibility in response to compressive force.
  • an upper portion of the inner side and an upper portion of the outer side of the support member is formed with a slit therebetween having a predetermined width, edges of the slit being fixed to one another such that an arc shaped portion is defined between the upper portion of the inner side and the upper portion of the outer side, the arc shaped portion forming an arched shape to a back side of upper portion
  • the edges of the slit are joined by stitching.
  • edges of the slit are joined by an adhesive.
  • the edges of the slit are joined by bonding.
  • the strap portion provides rigidity in response to leaning toward the outer side and flexibility in response to leaning toward the inner side.
  • an article of footwear includes a sole portion made of a sole forming material.
  • the sole portion has a fastening mechanism incorporated therein.
  • An upper portion is adhered to the sole portion.
  • the upper portion is formed with an outer layer, a support member and an inner liner with the support member being layered between the outer layer and the inner liner.
  • the support member has an inner side and an outer side, the inner side corresponding to an inner ankle side, and the outer side corresponding to an outer ankle side.
  • the inner side and the outer side are asymmetrical with respect to one another.
  • An upper portion of the inner side and an upper portion of the outer side are formed with a slit therebetween having a predetermined width.
  • the support member further includes a generally flexible strap portion extending between a lower portion of the inner side and the upper portion of the inner side, the flexible strap portion providing tensile force rigidity between the lower and upper portions of the inner side and flexibility in response to compressive force.
  • the edges of the slit are joined by stitching.
  • edges of the slit are joined by an adhesive.
  • the edges of the slit are joined by bonding.
  • the strap portion provides rigidity in response to leaning toward the outer side and flexibility in response to leaning toward the inner side.
  • a snowboard boot 1 is depicted in Fig. 1 in accordance with one embodiment of the present invention.
  • the snowboard boot 1 is an article of footwear and in-dudes a sole portion 2 that is made of a sole forming material.
  • the sole portion 2 has a fastening mechanism 2a incorporated therein.
  • the upper portion 6 is adhered to the sole portion 2.
  • the upper portion 6 is formed with an outer layer 8, a support member 11 and an inner liner 9 with the support member 11 being layered between the outer layer 8 and the inner liner 9.
  • the support member 11, as shown in Figs. 2, 3, 4 and 5, includes an inner side 20 and an outer side 25.
  • the inner side 20 corresponds to an inner ankle side
  • the outer side 25 corresponds to an outer ankle side.
  • the inner side would therefore correspond to the left side of a right hand boot.
  • the inner side would correspond to right side of a left boot.
  • the outer the inner side would correspond to -right side of a left boot.
  • the outer side would correspond to the left side of the left boot and the right side of the right boot.
  • the support member 11 is preferably made of a generally rigid plastic or polymer material, but may alternatively be made of other generally stiff (but slightly bendable) materials.
  • the inner side 20 and the outer side 25 are asymmetrical with respect to one another.
  • the support portion 11 is removed from the boot 1 and laid out flat.
  • An upper portion 21 of the inner side 20 extends outward as shown in Fig. 2 for connection to a strap 30, which is described in greater detail below.
  • An upper portion 26 of the outer side 25 extends outward in a direction opposite the upper portion 21, with respect to the depiction of the support member 11 in Fig. 2.
  • a lower portion 22 of the inner side 20 and a lower portion 27 of the outer side 25 also extend in opposite directions, with respect the depiction in Fig. 2.
  • the support member 11 is shown in perspective, as it would appear within the boot 11, but with the boot 1 removed for clarity.
  • the lower portion 22 and the lower portion 27 extend in directions generally parallel to one another to provide strength to the sides of the boot 1.
  • the upper portions 21 and 26 extend in a somewhat parallel manner with respect to one another to provide an upper portion of the boot 1 with support.
  • the support member 11 is formed at lower edges thereof with fingers F which extend under the area where the foot is placed in the boot 1, between the sole portion 2 and the upper portion 6.
  • a slit S is formed between the upper portion 21 and the upper portion 26.
  • the slit may be cut out of the support member or may be formed in a production process as the support member 11 is formed.
  • the sides of the slit S are fixed to one another to close the gap G defined by the slit, thus pulling the upper portion 21 and upper portion 26 toward one another.
  • the action of closing the gap G causes the upper portions 21 and 26 to define an arcuate shape A on the back side of the support member 11 and hence the boot 1, as shown in Figs 4 and 5.
  • the fixing of the sides of the slit S and the contour of the arcuate shape A are generally desirable for providing a rigid back for the boot 1.
  • a rigid back for the boot 1 is necessary for leaning operations of a snowboarder when riding a snowboard.
  • the support member further includes the strap portion 30 which extends between lower portion 22 of the inner side 20 and the upper portion 21 of the inner side 20.
  • the strap portion 30 provides tensile force rigidity between the lower and upper portions 22 and 21 of the inner side 20 and flexibility in response to compressive force.
  • the strap portion 30 may be made of any of a variety of materials, such as textile, plastic or the like.
  • the strap portion 30 may be fixed to the upper portion 21 and lower portion 22 by any of a variety of means, such as stitching, adhesive, or heat bonding with the material which forms the support member 11.
  • the slit S may be closed, with the sides fixed to one another by a variety of means such as stitching, joining by an adhesive or joining by heat bonding.
  • One of the main purposes of the strap portion 30 is to provide the boot 1 with rigidity in response to leaning toward the outer side and flexibility in response to leaning toward the inner side, as is described in greater detail below.
  • the snowboarder When a snowboarder is riding a snowboard and is wearing boots such as the boot 1, the snowboarder leans in various directions in order to steer.
  • the snowboarder is fixed to the snowboard by the boots, such as boots 1, with the boots extending in a direction generally perpendicular to the length of the snowboard.
  • Leaning backward, with respect to the direction of the boots causes the snowboard to turn in one direction.
  • Leaning forward, with respect to the boots causes the snowboard to turn in an opposite direction.
  • Leaning to the left or right, with respect to the direction of the boots provides a variety of steering and maneuvering effects. It is desirable for the boots to be responsive to the needs of the snowboarder, specifically to transmit specific body movements from the snowboarder, through the boots and to the snowboard.
  • the stiffness provided by the joined slit S gives rigidity to the back side of the boot 1 making it possible for the leaning backward movement of the snowboarder to be transferred to the snowboard.
  • the snowboarder may lean to a right side and to a left side (with respect to the boot 1).
  • the boot 1 In such movements, it is desirable for the boot 1 to be rigid when leaning toward the outer side 27 of the boot 1.
  • the strap portion 30 and the thickness of an upright portion 28 of the outer side 25 assures the rigidity of the boot 1.
  • flexibility is desirable.
  • a smaller upright portion 23 of the inner side 20 and the flexibility of the strap portion 30 allow for flexibility when leaning toward the inner side 20.
  • the support member 11 of the boot 1 was described with respect to inner and outer sides. It should therefore be understood that, although only one boot is described, the description refers to symmetrical right and left boots, each boot having an inner and an outer side.
  • the present invention relates to a snowboard boot having a support member that is asymmetrical.
  • the support member has inner and outer sides, each side having an upper and a lower portion.
  • the outer side is generally larger than the inner side.
  • the inner side includes a strap portion which extends within the boot from the upper portion and the lower portion of the inner side. The configuration of the strap portion and the support member provides the boot with rigidity in response to forces due to leaning toward the outer side of the boot and flexibility in response to leaning toward the inner side.
