Definitions

  • the present invention relates to a skate boot having a tendon guard with a recess for receiving an insert and wherein the flexibility of the tendon guard may be adjusted by a skater between different flexion modes.
  • Tendon guards are known to be used on hockey skates to protect the Achilles heel of the skater from being cut from another ice skate blade or from any other type of impact from another skater.
  • Document EP 1 716 771 discloses a skate boot with a tendon guard according to the preamble of claim 1.
  • tendon guards While tendon guards are capable of providing protection, the implementation of the tendon guard could result in a loss of flexibility of the skater's foot. More specifically, tendon guards which are too rigid can be obstructive to the extension of a skater's foot which regularly occurs during skating maneuvers. Such an obstruction is uncomfortable and undesirable for a skater as it can substantially affect performance.
  • tendon guards have been constructed with substantially flexible material in order to accommodate the flexing action of a skater's foot.
  • a skater is often limited by the design of the manufacturer in terms of the flexibility provided by the tendon guard.
  • skaters may be more likely to omit the use of the tendon guard than to search for a skate or tendon guard providing the desired level offlexibility.
  • skaters are likely to have different needs (and preferences) with regard to the level of flexibility of the tendon guard. For example, some skater's may prefer a tendon guard which exhibits a high level of flexibility while other may prefer a more rigid tendon guard. In addition, individual preferences may change over time, thereby further highlighting the deficiency of prior art tendon guards which are produced with a predefined flexibility.
  • U.S. Publication 2005/0229436 discloses a skate boot having an upper that includes a deformable region for facilitating the elastic dorsiflexion of the upper between an initial upper configuration and a dorsiflexed upper configuration.
  • the deformable region is substantially more elastically deformable than adjacent portions of the upper and provides an elastic force biasing the upper towards the initial configuration.
  • U.S. Patent 4,655,465 discloses a skate boot having a diamond shape cut-out in the back region of the skate boot for allowing forward and rearward flexing of the skate boot about the ankle joint, a cover placed over the cut-out to close it and a reinforcing member that covers the cover and cut-out and that is stitched to the skate boot.
  • the reinforcing member has a number of generally horizontal slits.
  • a skate boot for enclosing a human foot when in use, the foot having a heel, an ankle with a medial malleolus and a lateral malleolus, an Achilles tendon having an upper part and a lower part that projects away from the upper part, the lower part merging with the heel, a plantar surface, medial and lateral sides and toes.
  • the skate boot comprises an outer shell comprising a heel portion for receiving the heel of the foot; an ankle portion for receiving the ankle, the ankle portion comprising a rear portion for facing at least partially the lower part of the Achilles tendon; and medial and lateral side portions for facing the medial and lateral sides of the foot respectively.
  • the skate boot also comprises a tendon guard extending upwardly from the ankle portion of the outer shell for facing at least partially the upper part of the Achilles tendon, the tendon guard allowing backwards flexion of the ankle when the foot moves towards full extension.
  • the tendon guard comprises a recess for receiving an insert being adapted to be removably mounted in the recess.
  • the tendon guard has a first flexion mode when no insert is received in the recess and a second flexion mode when the insert is received in the recess, the second flexion mode being different from the first flexion mode.
  • Shown in Figures 1 and 2 is a typical right human foot F that includes toes T, a plantar surface PS, a medial side MS and a lateral side LS.
  • the human foot F includes a heel H, an Achilles tendon AT and an ankle A having a lateral malleolus LM and a medial malleolus MM, the lateral malleolus LM being at a lower position than the medial malleolus MM.
  • the Achilles tendon AT has an upper part UP and a lower part LP projecting away from the upper part UP, the lower part LP merging with the heel H.
  • FIG. 3 and 4 Shown in Figures 3 and 4 is an ice skate 1 that comprises a skate boot 10 suitable for enclosing the foot F.
  • a skate boot 10 suitable for enclosing the foot F.
  • the skate boot 10 shown in the figures is being used for an ice skate 1, it is understood that the skate boot 10 can be used for a roller skate.
  • the ice skate 1 has an outer shell 12 for receiving the foot F, a toe cap 14 made of rigid molded plastic for facing the toes T, a tongue 16 extending upwardly and rearwardly from the toe cap 14 for covering a forefoot of the foot F, a rigid insert 18 for providing more rigidity around the ankle A and heel H, an inner lining 20, a footbed 22, an insole 24, an outsole 26, an ice skate blade holder 28 and a blade 30.
  • the rigid insert 18 may be glued to an inner surface of the outer shell 12. It is understood that the rigid insert 18 is an optional component and may be eliminated if the outer shell 12 is sufficiently rigid for supporting the ankle A and heel H. Similarly, the insole 24 and outsole 26 are optional components and may be eliminated if the outer shell 12 is sufficiently rigid for receiving the blade holder 28.
  • the inner lining 20 is affixed to an inner surface of the outer shell 12 and it comprises an inner surface 32 intended for contact with the heel H, ankle A and medial and lateral sides MS, LS of the foot F in use. If the skate boot 10 comprises the rigid insert 18, such rigid insert 18 is sandwiched between the outer shell 12 and inner lining 20 and such inner lining 20 may be glued to the inner surfaces of the outer shell 12 and rigid insert 18 and stitched along its periphery to the outer shell 12.
  • the inner lining 20 is made of a soft material and can be a fabric made of 100% NYLON ® fibers.
  • the footbed 22 is mounted inside the outer shell 12 and it comprises an upper surface 34 for receiving the plantar surface PS and a wall 36 projecting upwardly from the upper surface 34. The wall 36 partially cups the heel H and extends up to a medial line of the foot F.
  • the skate boot 10 also comprises bands 38 secured to upper side portions of the outer shell 12.
  • the bands 38 may be made of fabric, textile or leather and comprise apertures 40. Eyelets 42 are punched into each of the bands 38, outer shell 12 and inner lining 20 vis-à-vis apertures 40.
  • the outer shell 12 may be made of a thermoformable material.
  • thermoformable material refers to a material that is capable of softening when heated and of hardening again when cooled.
  • Some non-limiting examples of different types of thermoformable material comprise ethylene vinyl acetate (EVA) foam, polyethylene foam, polystyrene foam, polypropylene foam and thermoformable materials sold under the trade-marks MEGABIX ® , SURLYN ® , SONTARA ® , FORMO500 ® , BYLON ® , MOSOCA ® and NYLON ® 66.
  • the outer shell 12 comprises a heel portion 44 for receiving the heel H, an ankle portion 46 for receiving the ankle A and medial and lateral side portions 48, 50 for facing the medial and lateral sides MS, LS respectively. These components form a foot receiving cavity that conforms to the general shape of the foot F.
  • the heel portion 44 may be thermoformed such that it is substantially cup shaped for following the contour of the heel H.
  • the ankle portion 46 comprises medial and lateral ankle sides 52, 54.
  • the medial ankle side 52 has a medial cup-shaped depression 56 for receiving the medial malleolus MM and the lateral ankle side 54 has a lateral cup-shaped depression 58 for receiving the lateral malleolus LM.
  • the lateral depression 58 is located slightly lower than the medial depression 56, for conforming to the morphology of the foot F.
  • the ankle portion 46 further comprises a rear portion 60 facing the lower part LP of the Achilles tendon AT.
  • the rear portion 60 may be thermoformed such that it follows the lower part LP of the Achilles tendon AT.
  • the medial and lateral side portions 48, 50 extend forwardly from the heel and ankle portions 44, 46.
  • the outer shell 12 also comprises a tendon guard 43 for facing at least partially the upper part UP of the Achilles tendon AT.
  • the tendon guard 43 allows backwards flexion of the ankle A when the foot F moves towards full extension.
  • the tendon guard 43 may be made of silicone or may be made by injection molding using polyester (e.g. polyester HYTREL ® ) polyurethane, polyamide, or other suitable thermoplastics.
  • the selected material may have enough flexibility to allow the tendon guard 43 to flex rearwardly when pressure is applied on it while it should also have enough resiliency to allow the tendon guard 43 to return to its initial position when pressure is no longer applied on it.
  • Figures 5 to 7 show a skater in different skating positions.
  • the flexing portion 80 allows backwards flexion of the ankle A when the foot F of the skater moves towards full extension.
  • the foot F of the skater moves forwardly without touching the ice and another pushing motion of the foot F will begin once the skate touches the ice again. It is understood that the tendon guard 43 should return to its initial position shown in Figure 5 once the full push extension of the foot is completed.
  • the tendon guard 43 in its initial position shown in full lines, the tendon guard 43 is in a generally vertical position.
  • the tendon guard 43 is then capable of flexing rearwardly of an angle ⁇ which may be up to 90o.
  • the tendon guard 43 will now be described in further detail with reference to Figures 10 to 21 .
  • the tendon guard 43 includes a bottom portion 74 and the flexing portion 80 that projects upwardly from the bottom portion 74 for facing at least partially the upper part UP of the Achilles tendon AT.
  • the bottom portion 74 of the tendon guard 43 is affixed to the ankle portion 46 as will be described in further detail below.
  • the tendon guard 43 may also comprise medial and lateral side portions 76, 78 extending forwardly from the bottom portion 74 and being affixed to the respective medial and lateral ankle sides 52, 54 of the ankle portion 46.
  • the bottom portion 74 of the tendon guard 43 acts as an attachment portion for attaching the tendon guard 43 to the outer shell 12. More specifically, the bottom portion 74 of the tendon guard 43 has a substantially U-shaped groove defined by a front wall 77 and a rear wall 79. The front and rear walls 77, 79 are at least partially receiving therebetween the top edge portion of the rear portion 60 of the ankle portion 46 when the tendon guard 43 is positioned onto the outer shell 12. As such, the tendon guard 43 can be easily attached to the outer shell 12.
  • the bottom portion 74 of the tendon guard 43 can form a single wall made of one or more layers that are attached to the inner or outer side of the top edge portion of the rear portion 60 of the ankle portion 46 or that are inserted and glued and/or affixed within layers of the outer shell.
  • the tendon guard 43 can be fixedly attached to the ankle portion 46 via stitching, over molding, thermal bonding, high frequency welding, vibration welding, piping, zipper, adhesive and staples, among other possibilities known in the art.
  • the tendon guard may alternatively form an integral part of the outer shell or the upper part of the ankle portion.
  • the tendon guard may be removably attached to the outer shell such that the skater can replace the tendon guard should the tendon guard be damaged or can select among different tendon guards.
  • the tendon guard 43 has an inner surface 90 and an outer surface 92. As shown in Figure 12 , the inner surface 90 may have a projection 96 for increasing attachment bonding between the tendon guard 43 and the outer shell 12. The inner surface 90 may be covered by the inner lining 20 such that the inner surface of the outer shell 12 shows a uniform lining surface.
  • the outer surface 92 may have a series of reinforcement elements defined by regions of increased thickness (as depicted by projections 98) and/or a series of regions of decreased thickness (as depicted by recesses 99). As such, specific regions of the tendon guard 43 can be made thicker to rigidify the tendon guard 43 in those regions, while other regions can be made thinner to increase the flexibility of the tendon guard 43 in those regions.
  • the tendon guard may also have projections and/or recesses that are for aesthetic value.
  • the tendon guard 43 has a substantially symmetrical arrangement and could be used to protect the Achilles tendon of either of the right or left legs.
  • the tendon guard can be shaped to specifically fit a given one of the right or left legs.
  • different tendon guards can be shaped to have an additional protective portion which at least partially wraps around a lateral portion of the respective leg in order to provide further protection.
  • a given tendon guard may not be symmetrical along its longitudinal axis.
  • the lower region of the flexing portion 80 acts as a flexible hinge. As such, it may be desirable to increase the thickness of the tendon guard 43 in the lower region to enable the tendon guard 43 to sustain tensile and compressive forces incurred during bending and to avoid plastic deformation of the tendon guard 43.
  • the flexibility of the tendon guard 43 can be selectively designed based on different parameters such as its thickness, shape, material and the presence of projections and/or recesses.
  • the tendon guard 43 comprises a recess 100 for receiving an insert 102 (shown in Figures 14 to 16 ).
  • the recess 100 may be a longitudinal recess that extends in a direction generally transverse to a longitudinal axis A-A of the tendon guard 43.
  • the inserts 102 have a core 102A and connection means permitting removable connection between a given insert 102 and the tendon guard 43.
  • the insert 102 may have connection means including protrusions 102B, 102C, 102D and 102E.
  • the recess 100 of the tendon guard 43 may comprise a housing portion 100A with upper and lower walls 100F, 100G provided in the tendon guard 43 and the recess 100 may also comprise grooves extending upwardly and downwardly in the tendon guard 43 (only grooves 100B, 100C are shown in Figure 17 ).
  • the main housing portion 100A of the recess 100 receives the core 102A of the insert 102 while the grooves of the recess 100 cooperate with corresponding protrusions 102B, 102C, 102D, 102E of the insert 102.
  • the tendon guard may include protrusions while the inserts may include respective grooves.
  • the insert can be mounted to the tendon guard 43 by being press-fit or snap-fit into the recess.
  • the recess 100 is shown as having a substantially rectangular shape, the recess can have any shape suitable to receive a correspondingly shaped insert.
  • the flexing portion 80 of the tendon guard 43 can be bent in a forward direction (i.e.: opposite to the bending shown in Figures 18A and 18B ).
  • the recess of the tendon guard 43 will therefore open by a substantial amount, thereby permitting a skater to more easily place or remove a given insert into the recess.
  • the natural resiliency of the tendon guard 43 will bias the flexing portion 80 of the tendon guard 43 to its initial position, thereby snugly holding the insert in place and avoiding that the insert become undesirably dislodged from the recess during use of the tendon guard 43.
  • the core 102A of the insert 102 may be made of a resilient material to permit compression of the core 102A when the upper and lower walls 100F, 100G abut against respective upper and lower surfaces 102F, 102G of the insert 102. As such, when the tendon guard 43 bends, the upper and lower walls 100F, 100G will compress the core 102A of the insert 102 by pressing against the upper and lower surfaces 102F, 102G.
  • the resilient material of the core 102A permits such a compression.
  • the core 102A can be made of rubber such as natural rubber, isoprene rubber, polychloroprene, styrene butadiene rubber, etc.
  • the insert 102 and/or core 102A of the insert 102 may have hardness values between 20 Shore A and 70 Shore D.
  • a very hard insert may have a hardness value between 60 and 70 Shore D
  • a hard insert may have a hardness value between 40 and 50 Shore D
  • a medium insert may have a hardness value between 20 and 30 Shore D
  • a soft insert may have a hardness value between 5 and 15 Shore D
  • a very soft insert may have a hardness value between 15 and 25 Shore A.
  • the insert may comprise a frame, skeleton or armature made of a relatively rigid material being covered or overmolded by a material having a hardness value lower from the one of the rigid material.
  • the protrusions 102B, 102C, 102D, 102E of the inserts 102 can be made of a more rigid material in order to be fixedly secured into their corresponding grooves.
  • the protrusions can be made of plastic such as polyvinyl chloride, polytetrafluoroethylene, polyethylene (low density or high density), polypropylene, etc.
  • the core 102A of the insert 102 has a length L, a height H and a thickness T. While the core 102A of the insert 102 is not of exact rectangular geometry, dimensions of length L, height H, and thickness T are used for simplicity. It is nevertheless understood that the core 102A of the insert 102 can have a variety of shapes while remaining within the scope of the present invention. For example, the core 102A of the insert 102 can be generally triangular or can have a curved periphery.
  • Different inserts can therefore be manufactured with different dimensions and different material in order to provide different levels of flexibility to the tendon guard 43 when inserted in the recess 100.
  • the height H and thickness T of the core may largely determine the amount of flexibility permitted by the tendon guard 43.
  • the cores of the inserts can be made of different material but may have the same dimensions of length L, height H and thickness T.
  • the dimensions and the material can be changed from one insert to another. It can therefore be understood that a variety of different inserts can be manufactured to provide different levels of flexibility for the tendon guard 43.
  • a skater is able to adjust the flexibility of the tendon guard 43 as desired. This allows the skater to experiment with several different types of inserts in order to achieve a desired level of flexibility. On the other hand, if the skater determines that the natural resiliency of the tendon guard 43 without an insert is adequate, the tendon guard 43 can simply be used with the recess 100 being free of any inserts.
  • Figures 18A and 18B illustrate a tendon guard 43 having two different flexion modes. While it is understood that, during use, the tendon guard 43 is likely to experience bending under a pressure exerted on its inner surface, an equivalent force vector F is depicted in the figures for simplicity of illustration.
  • flexion force or “pressure” can be understood to represent any type of physical force or pressure capable of bending the tendon guard 43.
  • the tendon guard 43 is shown in an initial position in solid lines and in a bent position in dotted lines.
  • a first insert 102 1 is positioned in the recess 100 of the tendon guard 43 while in Figure 18B , a second insert 102 2 different from the first insert 102 1 is positioned in the recess 100 of the tendon guard 43.
  • Force vector F which schematically depicts a flexion force which would be exhibited by the skater's leg, is the same in both cases and is applied at the same point on the tendon guard 43 in order to represent equivalent pressures in each of Figures 18A and 18B . While force vector F is shown as being applied along a particular line of action, it can be understood that other forces can be applied to the tendon guard 43 along any line of action to cause the tendon guard 43 to experience a backwards bending motion (flexing motion).
  • the tendon guard 43 with the first insert 102 1 ( Figure 18A ) defines a first flexing angle ⁇ 1 (a first bent position of the tendon guard 43 shown in dotted lines), while the tendon guard 43 with the second insert 102 2 ( Figure 18B ) defines a second flexing angle ⁇ 2 (a second bent position of the tendon guard 43 shown in dotted lines), the second flexion mode being different from the first flexion mode because each of the inserts 100 1 , 100 2 has different specifications.
  • the tendon guard 43 has the flexing portion 80.
  • the flexing portion 80 flexes from its initial position to a first bent position being at a first angle ⁇ 1 from its initial position ( Figure 18A ), and when the second insert 102 2 is received in the recess 100, the flexing portion 80 flexes from its initial position to a second bent position being at a second flexing angle ⁇ 2 from its initial position ( Figure 18B ), the first angle ⁇ 1 being different from the second flexing angle ⁇ 2 because each of the inserts 100 1 , 100 2 has different specifications.
  • a first backwards flexion of the skater's ankle A is permitted when the first insert 102 1 is received in the recess 100 of the tendon guard 43, which then has a first flexing mode
  • a second backwards flexion of the skater's ankle A is permitted when the second insert 102 2 is received in the recess 100 of the tendon guard 43, which then has a second flexing mode, the second flexing mode being different from the first flexing mode.
  • this tendon guard 43 may return to its initial position shown in solid lines according to different counter-forces because each of the inserts 102 1 , 102 2 produces a determined force which counters the backwards bending of the tendon guard 43. More specifically, the upper and lower walls 100F, 100G will compress the inserts 102 1 , 102 2 when the flexing portion 80 is bent. As such, the different inserts 102 1 , 102 2 (which have different specifications) will exert different amounts of counter-force on the upper and lower walls 100F, 100G.
  • Specifications may refer to any mechanical property or dimension of a given insert (such as hardness, density, shape, thickness, etc.).
  • the first insert 102 1 is different from the corresponding specification of the second insert 102 2 .
  • the first insert 102 1 is made of a material which has a greater hardness value than the material of the second insert 102 2 .
  • the first insert 102 1 may have a hardness value higher than 30 Shore A while the second insert 102 2 may have a hardness value lower than 30 Shore A, or the first insert 102 1 may have a hardness value higher than 40 Shore A while the second insert 102 2 may have a hardness value lower than 40 Shore A, or the first insert 102 1 may have a hardness value higher than 50 Shore A while the second insert 102 2 may have a hardness value lower than 50 Shore A, etc.
  • the first insert 102 1 has a different physical dimension (such as a greater height H) than the second insert 102 2 .
  • the first insert 102 1 may have a full body while the second insert 102 2 may have a slit, groove or opening provided therein.
  • the shape and/or dimension of the first insert 102 1 is designed such that the first insert 102 1 is substantially confined in the recess when received therein while the shape and/or dimension of the first insert 102 2 is designed such that the second insert 102 2 is slightly smaller than the recess thereby creating a gap between the insert 102 2 and the walls of recess when the second insert 102 2 is received in the recess.
  • Figure 19 to 21 show a tendon guard 243 with a central slit 245 in order to facilitate the placement and removal of the inserts 102 1 , 102 2 in the recess 100.
  • the slit 245 extends from the bottom portion of the tendon guard 243 in a direction towards the flexing portion of the tendon guard 243 and is generally parallel to the longitudinal axis A-A of the tendon guard 243. As shown, the slit 245 crosses the recess 100, and generally splits the tendon guard 243 into two portions (namely, a left portion 243A and a right portion 243B) thereby allowing a skater to bend the tendon guard 243. While the two portions 243A, 243B are shown to be of substantially similar size, it can be understood that the slit 245 can be cut onto the tendon guard such as to create left and right portions of different sizes and dimensions.
  • the tendon guard 243 may be seen as being within a plane P.
  • the tendon guard 243 is capable of experiencing out-of-plane bending (as shown in Figure 20 ) as well as in-plane bending (as shown in Figure 21 ). More specifically, the out-of-plane bending allows one portion (243B) to move relative to the other portion (243A) such that they define an angle ⁇ between one another ( Figure 20 ). In addition, the in-plane bending allows the portions 243A, 243B to define an angle ⁇ ( Figure 21 ).
  • angle ⁇ can have a value between 0° and 45° and angle ⁇ can have a value between 0° and 30°.
  • the dimensions of the slit 245 can also determine the possible ranges of angles ⁇ and ⁇ . It is understood that the slit 245 may be replaced by a recess or groove generally extending along the longitudinal axis A-A for allowing the in-plane bending only.
  • the ability of the portions 243A, 243B to exhibit in-plane and out-of-plane bending facilitates the placement and removal of the inserts into the recess 100.
  • the tendon guard would be removably attached to the outer shell 12 such that the skater is able to remove the tendon guard 243 from the outer shell 12 if he or she desires changing the insert.
