Description

ICE SKATE
FIELD
The invention generally relates to ice skates, including their blade holder and their blade.
BACKGROUND
An ice skate includes a skate boot for receiving a skater's foot and a blade holder connecting a blade to the skate boot. Many different types of skate boots, blade holders and blades have been developed in order to provide skates which can accommodate different skating maneuvers as well as to provide certain benefits to skaters.
As with most sports equipment, a visual appearance of a skate is an important consideration for a skater using it. For this reason, various efforts have been made which resulted in numerous skates with different designs of skate boots being available. However, variations in visual appearance of blade holders have been generally limited in comparison. For instance, while blade holders of different shapes have been developed (e.g., depending on different manufacturers), there has been little effort directed to other aesthetic aspects of the blade holders.
Notably, conventional blade holders are typically in a single color, mostly white, and while some blade holders have implemented darker/shaded areas, these are generally limited to logos and/or other graphics that occupy very small areas.
For these and/or other reasons, there is a need to improve ice skates, including their blade holder.

DETAILED DESCRIPTION OF EMBODIMENTS
Figures 1 and 2 show an example of an ice skate 10 in accordance with an embodiment of the invention. The ice skate 10 comprises a skate boot 11 for enclosing a skater's foot, a blade holder 28, and a blade 52 for contacting an ice surface 5 on which the skater skates. In this embodiment, the ice skate 10 is a hockey skate designed for playing ice hockey. In other embodiments, the ice skate 10 may be designed for other types of skating activities.
As further discussed below, in this embodiment, a visual appearance of the blade holder 28 may be designed such that the blade holder 28 has visual characteristics
6 enhancing its aesthetics and/or other aspects related to its visual appearance (e.g., an effect on the skater, elaborateness and/or customization of its visual appearance, etc.).
In this embodiment, this is achieved while the blade holder 28 is lightweight and/or provides other performance benefits to the skater. For example, in this embodiment, selected parts of an exterior 27 of the blade holder 28 are colored differently for aesthetic and/or other purposes. Also, in this embodiment, the blade holder 28 is designed to optimize its weight and performance characteristics, including greater stiffness in certain areas (e.g., front and heel areas) and greater feel and control in other areas (e.g., along an interface with the blade 52). For instance, in this embodiment, the blade holder 28 comprises an arrangement of different materials (e.g., a composite material and a polymeric material) that differ in stiffness and density and are strategically distributed in the blade holder 28. These different materials are related to the selected parts of the exterior 27 of the blade holder 28 that are colored differently.
The skate boot 11 defines a cavity 26 for receiving the skater's foot. With additional reference to Figures 54 and 55, the skater's foot includes toes T, a ball B, an arch ARC, a plantar surface PS, a top surface TS, a medial side MS and a lateral side LS.
The top surface TS of the skater's foot is continuous with a lower portion of the skater's shin S. In addition, the skater has a heel H, an Achilles tendon AT, and an ankle A
having a medial malleolus MM and a lateral malleolus LM that is at a lower position than the medial malleolus MM. The Achilles tendon AT has an upper part UP and a lower part LP projecting outwardly with relation to the upper part UP and merging with the heel H. A forefoot of the skater includes the toes T and the ball B, a hindfoot of the skater includes the heel H, and a midfoot of the skater is between the forefoot and midfoot.
In this embodiment, the skate boot 11 comprises a front portion 17 for receiving the toes T of the skater's foot, a rear portion 19 for receiving the heel H of the skater's foot, and an intermediate portion 21 between the front portion 17 and the rear portion 19.
7 More particularly, in this embodiment, the skate boot 11 comprises an outer shell 12, a toe cap 14 for facing the toes T, a tongue 16 extending upwardly and rearwardly from the toe cap 14 for covering the top surface TS of the skater's foot, a rigid insert 18 for providing more rigidity around the ankle A and the heel H of the skater's foot, an inner lining 20, a footbed 22, and an insole 24. The skate boot 11 also comprises lace members 38 and eyelets 42 punched into the lace members 38, the outer shell 12 and the inner lining 20 vis-à-vis apertures 40 in order to receive laces for tying on the skate 10.
The inner lining 20 is affixed to an inner surface of the outer shell 12 and comprises an inner surface 32 intended for contact with the heel H and medial and lateral sides MS, LS of the skater's foot and the skater's ankle A in use. The inner lining 20 may be made of a soft material (e.g., a fabric made of NYLON fibers or any other suitable fabric). The rigid insert 18 is sandwiched between the outer shell 12 and the inner lining 20 and may be affixed in any suitable way (e.g., glued to the inner surface of the outer shell 12 and stitched along its periphery to the outer shell 12). The footbed 22 is mounted inside the outer shell 12 and comprises an upper surface 34 for receiving the plantar surface PS of the skater's foot and a wall 36 projecting upwardly from the upper surface 34 to partially cup the heel H and extend up to a medial line of the skater's foot.
The insole 24 has an upper surface 25 for facing the plantar surface PS of the skater's foot and a lower surface 23 on which the outer shell 12 may be affixed.
The outer shell 12 is molded (e.g., thermoformed) such that it 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 50, 60 for facing the medial and lateral sides MS, LS of the skater's foot, respectively. The medial and lateral side portions 50, 60 include upper edges 51, 61 which connect to the lace members 38. The heel portion 44 may be formed 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
8 receiving the lateral malleolus LM of the skater. The lateral depression 58 is located slightly lower than the medial depression 56, for conforming to the morphology of the skater's foot. The ankle portion 46 further comprises a rear portion 47 facing the lower part LP of the Achilles tendon AT. The rear portion 47 may be thermoformed such that it follows the lower part LP of the Achilles tendon AT. Furthermore, the skate boot 11 also includes a tendon guard 43 affixed to the rear portion 47 of the ankle portion 46 and extending upwardly therefrom.
The skate boot 11 may be constructed in any other suitable way in other embodiments. For example, in other embodiments, various components of the skate boot 11 mentioned above may be configured differently or omitted and/or the skate boot 11 may comprise any other components that may be made of any other suitable materials and/or using any other suitable processes.
With additional reference to Figures 3 to 8, the blade holder 28 comprises a lower portion 64 comprising a blade-retaining base 80 that retains the blade 52 and an upper portion 62 comprising a support 82 that extends upwardly from the blade-retaining base 80 towards the skate boot 11 to interconnect the blade holder 28 and the skate boot 11. A front portion 66 of the blade holder 28 and a rear portion 68 of the blade holder 28 define a longitudinal axis 65 of the blade holder 28. The front portion 66 of the blade holder 28 includes a front 154 of the blade holder 28 and extends beneath and along the skater's forefoot in use, while the rear portion 68 of the blade holder 28 includes a rear 156 of the blade holder 28 and extends beneath and along the skater's hindfoot in use. An intermediate portion 74 of the blade holder 28 is between the front and rear portions 66, 68 of the blade holder 28 and extends beneath and along the skater's midfoot in use. A length L of the blade holder 28 can be measured from a frontmost point 70 to a rearmost point 72 of the blade holder 28.
The blade holder 28 comprises a medial side 71 and a lateral side 67 that are opposite one another. The blade holder 28 has a longitudinal direction (i.e., a direction generally parallel to its longitudinal axis 65) and transversal directions (i.e., directions transverse to its longitudinal axis 65), including a widthwise direction (i.e.,
9 a lateral direction generally perpendicular to its longitudinal axis 65). The blade holder 28 also has a height direction normal to its longitudinal and widthwise directions.
The blade-retaining base 80 is elongated in the longitudinal direction of the blade holder 28 and is configured to retain the blade 52 such that the blade 52 extends along a bottom portion 73 of the blade-retaining base 80 to contact the ice surface.
To that end, the blade-retaining base 80 comprises a blade-retention portion 75 to face and retain the blade 52. In this embodiment, the blade-retention portion comprises a recess 76 in which an upper portion of the blade 52 is disposed.
The blade holder 28 can retain the blade 52 in any suitable way. In this embodiment, with additional reference to Figures 23A to 23C, the blade holder 28 comprises a blade-detachment mechanism 55 such that the blade 52 is selectively detachable and removable from, and attachable to, the blade holder 28 (e.g., when the blade 52 is worn out or otherwise needs to be replaced or removed from the blade holder 28).
More particularly, in this embodiment, the blade 52 includes a plurality of projections 531, 532. The blade-detachment mechanism 55 includes an actuator 115 and a biasing element 117 which biases the actuator 115 in a direction towards the front portion 66 of the blade holder 28. To attach the blade 52 to the blade holder 28, the front projection 531 is first positioned within a hollow space 119 (e.g., a recess or hole) of the blade holder 28. The rear projection 532 can then be pushed upwardly into a hollow space 121 (e.g., a recess or hole) of the blade holder 28, thereby causing the biasing element 117 to bend and the actuator 115 to move in a rearward direction. The rear projection 532 will eventually reach a position which will allow the biasing element 117 to force the actuator 115 towards the front portion 66 of the blade holder 28, thereby locking the blade 52 in place. The blade 52 can then be removed by pushing against a finger-actuating surface 123 of the actuator 115 to release the rear projection 532 from the hollow space 121 of the blade holder 28.
Further information on examples of implementation of the blade-detachment mechanism 55 in some embodiments may be obtained from U.S. Patent 8,454,030 hereby incorporated by reference herein. The blade-detachment mechanism 55 may be configured in any other suitable way in other embodiments.
In this embodiment, the blade-retaining base 80 comprises a plurality of apertures 811-814 distributed in the longitudinal direction of the blade holder 28 and extending from the medial side 71 to the lateral side 67 of the blade holder 28. In this example, respective ones of the apertures 811-814 differ in size. More particularly, in this example, the apertures 811-814 decrease in size towards the front portion 66 of the blade holder 28. The apertures 811-814 may have any other suitable configuration, or may be omitted, in other embodiments.
The blade-retaining base 80 may be configured in any other suitable way in other embodiments.
The support 82 is configured for supporting the skate boot 11 above the blade-retaining base 80 and transmit forces to and from the blade-retaining base 80 during skating. In this embodiment, the support 82 comprises a front pillar 84 and a rear pillar 86 which extend upwardly from the blade-retaining base 80 towards the skate boot 11. The front pillar 84 extends towards the front portion 17 of the skate boot 11 and the rear pillar 86 extends towards the rear portion 19 of the skate boot 11. The blade-retaining base 80 extends from the front pillar 84 to the rear pillar 86. More particularly, in this embodiment, the blade-retaining base 80 comprises a bridge 88 interconnecting the front and rear pillars 84, 86.
The support 82 and the skate boot 11 can be connected to one another in any suitable way. In this embodiment, the support 82 is affixed to the skate boot 11.
More particularly, in this embodiment, the front and rear pillars 84, 86 are fastened to the skate boot 11 by fasteners (e.g., rivets, screws, bolts). In this example, each of the front and rear pillars 84, 86 comprises a flange 87 including a plurality of apertures 891-89F to receive respective ones of the fasteners that fasten the blade holder 28 to the skate boot 11. The support 82 may be affixed to the skate boot 11 in any other suitable manner in other embodiments (e.g., by an adhesive).
The support 82 may be configured in any other suitable way in other embodiments.
The visual appearance of the blade holder 28 may be designed to enhance its aesthetics and/or other aspects related to its visual appearance. Notably, in this embodiment, substantial parts 1601-160p of the exterior 27 of the blade holder are colored differently for aesthetic and/or other purposes. In that sense, with the substantial parts 1601-160p of its exterior 27 being chromatically different, the blade holder 28 may be referred to as being a "polychromatic" blade holder.
The exterior 27 of the blade holder 28 is that outer part (e.g., surface) of the blade holder 28 that is visible and faces outwardly away from the blade holder 28.
It comprises the medial side 71, the lateral side 67, the front 154, and the rear 156 of the blade holder 28. Thus, the exterior 27 of the blade holder 28 includes an exterior 162 of the support 82 and an exterior 164 of the blade-retaining base 80, which are respectively that outer part (e.g., surface) of the support 82 that is visible and faces outwardly away from the support 82 and that outer part (e.g., surface) of the blade-retaining base 80 that is visible and faces outwardly away from the blade-retaining base 80. The exterior 162 of the support 82 comprises a lateral side 166, a medial side 167, a front 170, and a rear 173 of the support 82, while the exterior 164 of the blade-retaining base 80 comprises a lateral side 174, a medial side 176, a front 178, and a rear 180 of the blade-retaining base 80.
More particularly, in this embodiment, the exterior 162 of the support 82 and the exterior 164 of the blade-retaining base 80 are at least mainly (i.e., mainly or entirely) colored differently. That is, at least a main part (i.e., a main part or an entirety) of the exterior 162 of the support 82 and at least a main part of the exterior 164 of the blade-retaining base 80 exhibit different colors. Any suitable colors may be used, such as, for example: white, black, and gray, which are considered colors herein; red, blue, yellow, etc.; and any shade thereof.
The different colors exhibited by the exterior 162 of the support 82 and the exterior 164 of the blade-retaining base 80 may be arranged in any suitable way. In this embodiment, a relatively lighter portion of the exterior 27 of the blade holder 28 (i.e., exhibiting one or more lighter colors such as white or whitish shades) may be significant, whereas a relatively darker portion of the exterior 27 of the blade holder 28 (i.e., exhibiting one or more darker colors such as gray, black, red, blue or darker shades) may be more limited or less noticeable by the skater while skating. In some cases, this may be desirable as blade holders which are too dark have sometimes been less appreciated by skaters who may be perceived by others as skating slower when wearing blade holders which are too dark and/or who may sometimes feel that this affects their performance, such as by apparently making them believe or feel that they skate slower.
In this embodiment, at least a majority (i.e., a majority or the entirety) of the exterior 162 of the support 82 is colored differently than at least a majority of the exterior 164 of the blade-retaining base 80.
For instance, in some embodiments, at least 75%, in some cases at least 90%, and in some cases substantially an entirety of the exterior 162 of the support 82 may be colored differently than at least 75% of the exterior 164 of the blade-retaining base 80.
In some embodiments, at least the majority of the exterior 162 of the support 82 may be darker than at least the majority of the exterior 164 of the blade-retaining base 80. In other words, at least a majority of the exterior 162 of the support 82 may contrast at least the majority of the exterior 164 of the blade-retaining base 80. For example, a color 135 of the exterior 162 of the support 82 that is at least predominant (i.e., a predominant or sole color) on the exterior 162 of the support 82 may be different from a color 137 of the exterior 164 of the blade-retaining base 80 that is at least predominant on the exterior 164 of the blade-retaining base 80.
Notably, in some cases, the color 135 of the exterior 162 of the support 82 that is at least predominant on the exterior 162 of the support 82 may be darker than the color 137 of the exterior 164 of the blade-retaining base 80 that is at least predominant on the exterior 164 of the blade-retaining base 80.
As such, a sole or main color 135 of the exterior 162 of the support 82 may be different from a sole or main color 137 of the exterior 164 of the blade-retaining base 80. For example, the sole or main color 135 of the exterior 162 of the support may be darker than the sole or main 137 color of the exterior 164 of the blade-retaining base 80.
In this example, the exterior 162 of the support 82 includes an exterior 139 of the front pillar 84 and an exterior 141 of the rear pillar 86. In some cases, at least a majority of the exterior 139 of the front pillar 84 and at least a majority of the exterior 141 of the rear pillar 84 may be colored differently than at least the majority of the exterior 164 of the blade-retaining base 80; in some cases, at least 75% of the exterior 139 of the front pillar 84 and at least 75% of the exterior 141 of the rear pillar 86 may be colored differently than at least 75% of the exterior 164 of the blade-retaining base 80; in some cases, at least 90% of the exterior 139 of the front pillar 84 and at least 90% of the exterior 141 of the rear pillar 86 may be colored differently than at least 90% of the exterior 164 of the blade-retaining base 80; and in some cases, substantially an entirety of the exterior 139 of the front pillar 84 and substantially an entirety of the exterior 141 of the rear pillar 86 may be colored differently than substantially an entirety of the exterior 164 of the blade-retaining base 80. For instance, in some examples of implementation, at least the majority of the exterior 139 of the front pillar 84 and at least the majority of the exterior 141 of the rear pillar 86 may be darker than at least the majority of the exterior 164 of the blade-retaining base 80.

In some embodiments, a color 142 of the exterior 139 of the front pillar 84 that is at least predominant on the exterior 139 of the front pillar 84 and a color 143 of the exterior 141 of the rear pillar 86 that is at least predominant on the exterior 141 of the rear pillar 86 may be different from the color 137 of the exterior 164 of the blade-retaining base 80 that is at least predominant on the exterior 164 of the blade-retaining base 80. For example, the color 142 of the exterior 139 of the front pillar 84 and the color 143 of the exterior 141 of the rear pillar 86 may be darker than the color 137 of the exterior 164 of the blade-retaining base 80.
Moreover, in some embodiments, a sole or main color 142 of the exterior 139 of the front pillar 84 and a sole of main color 143 of the exterior 141 of the rear pillar 86 may be different from the sole or main color 137 of the exterior 164 of the blade-retaining base 80. For example, the sole or main color 142 of the exterior 139 of the front pillar 84 and the sole or main color 143 of the exterior 141 of the rear pillar 86 may be darker than the sole or main color 137 of the exterior 164 of the blade-retaining base 80.
In some embodiments, as shown in Figure 22, the exterior 162 of the support 82 may have a plurality of colors CLi-CLN. Moreover, the exterior 162 of the support 82 may have more colors CLi-CLN than the exterior 164 of the blade-retaining base 80.
For example, in some cases, the colors CLi-CLN of the exterior 162 of the support 82 may include at least two colors, in some cases at least three colors, in some cases at least four colors, and in some cases even more colors. Although in this embodiment, the exterior 164 of the blade-retaining base 80 is illustrated as having a single color 137, the exterior 164 of the blade-retaining base 80 may have a plurality of colors.
Moreover, in some embodiments, the exterior 162 of the support 82 may exhibit a gradual variation between respective ones of its colors CLi-CLN. That is, a transition region 165 may exist between the different colors CLi-CLN of the exterior 162 of the support 82 where a given one of the colors CLi-CLN of the exterior 162 of the support 82 gradually (i.e., rather than abruptly) changes into another of the colors CLi-CLN of the exterior 162 of the support 82.
In some embodiments, an interface 105 of the different colors of the support 82 and the blade-retaining base 80 may extend over at least a substantial part of the length L of the blade holder 28. That is, the interface 105 between one or more of the colors CLi-CLN of the exterior 162 of the support 82 and the color 137 (or the plurality of colors) of the blade-retaining base 80 may extend longitudinally along a significant portion of the length L of the blade holder 28. For instance, in some cases the interface 105 of different colors of the support 82 and the blade-retaining base 80 may extend over at least 20% of the length L of the blade holder 28, in some cases over at least 30% of the length L of the blade holder 28, in some cases over at least a majority of the length L of the blade holder 28, and in some cases even more.
In this embodiment, the blade holder 28 is characterized by a material distribution profile to optimize its weight and performance characteristics. Notably, in this embodiment, the material distribution profile of the blade holder 28 results in a variation in density and a variation in rigidity across certain areas of the blade holder 28 to reduce its weight while providing greater stiffness in some areas (e.g., the front and rear pillars 84, 86) where more rigidity may be desirable (e.g., to better transmit forces) and greater compliance (i.e., less stiffness) in other areas (e.g., along the blade-retaining base 80) where less rigidity may be desirable (e.g., for better feel and control). In this example, the material distribution profile of the blade holder 28 is used to provide the substantial parts 1601-160p of its exterior 27 that are differently colored.
The material distribution profile is designed such that the blade holder 28 comprises an arrangement of different materials M1, M2 disposed in selected areas of the blade holder 28. The different materials M1, M2 belong to different classes of materials (i.e., polymers, metals, ceramics and composites) and/or exhibit substantially different values of a given material property (e.g., modulus of elasticity, tensile strength, density, etc.).

In this embodiment, the material M1 is stiffer (i.e., more rigid) than the material M2 and makes up at least a major part (i.e., a major part or an entirety) of the support 82 of the upper portion 62 of the blade holder 28, while the material M2 makes up at least a major part of the blade-retaining base 80 of the lower portion 64 of the blade holder 28. More particularly, in this embodiment, the material M1 makes up at least a major part of each of the front and rear pillars 84, 86 and the material M2 makes up at least a major part of the blade-retaining base 80. This makes the front and rear pillars 84, 86 of the blade holder 28 stiffer, which may better transmit forces and provide more strength during skating, while making the blade-retaining base 80 less stiff, which may allow for better feel and control during skating.
More particularly, in this embodiment, with additional reference to Figures 10 to 21, each of the front and rear pillars 84, 86 is at least mainly (i.e., mainly or entirely) made of the material M1, while the blade-retaining base 80 is at least mainly made of the material M2. In this example, each of the front and rear pillars 84, 86 is entirely made of the material M1, while a major part 63 of the blade-retaining base 80 is made of the material M2 and a thin upper part 69 of the bridge 88 of the blade-retaining base 80 is made of the material M1 (i.e., at least a majority of the bridge 88 is made of the material M2). More specifically, in this example, the thin upper part 69 of the bridge 88 of the blade-retaining base 80 is integrally formed and continuous with the front and rear pillars 84, 86 such that the thin upper part 69 of the bridge 88 and the front and rear pillars 84, 86 constitute a monolithic one-piece upper component 77 of the blade holder 28 that is made of the material M1, while the major part 63 of the blade-retaining base 80 constitutes a monolithic one-piece lower component 78 of the blade holder 28 that is made of the material M2. In other embodiments, different parts of the front and rear pillars 84, 86 and the blade-retaining base 80 may be made of the materials M1, M2.
The materials M1, M2 may differ in rigidity to any suitable degree. For example, in some embodiments, a ratio A1/A2 of a modulus of elasticity A1 (e.g., tensile modulus) of the material Mi over a modulus of elasticity A2 of the material M2 may be at least 2, in some cases at least 5, in some cases at least 10, in some cases at least 20, in some cases at least 50, and in some cases even more (e.g., at least 100). This ratio may have any other suitable value in other embodiments.
For instance, in some embodiments, the modulus of elasticity Ai of the material Mi may be at least 25 GPa, in some cases at least 50 GPa, in some cases at least GPa, and in some cases even more (e.g., at least 150 GPa or 200 GPa), and/or the modulus of elasticity A2 of the material M2 may be no more than 20 GPa, in some cases no more than 10 GPa, in some cases no more than 5 GPa, and in some cases even less (e.g., no more than 2 GPa or 1 GPa). The modulus of elasticity Ai of the material Mi and/or the modulus of elasticity A2 of the material M2 may have any other suitable value in other embodiments.
In this embodiment, the material Mi is denser than the material M2 and, thus, in addition to making the blade-retaining base 80 less stiff for better feel and control, the material M2 which is less dense than the material Mi helps to reduce the weight of the blade holder 28.
The materials M1, M2 may differ in density to any suitable degree. For example, in some embodiments, a ratio p1/p2 of a density pi of the material Mi over a density p2 of the material M2 may be at least 1.1, in some cases at least 1.2, in some cases at least 1.3, and in some cases even more (e.g., at least 1.5). This ratio may have any other suitable value in other embodiments.
For instance, in some embodiments, the density pi of the material Mi may be at least 1 g/cm3, in some cases at least 1.2 g/cm3, in some cases at least 1.4 g/cm3, in some cases at least 1.8 g/cm3, in some cases at least 2 g/cm3, and in some cases even more (e.g., at least 2.5 g/cm3 or 3 g/cm3), and/or the density p2 of the material M2 may be no more than 2 g/cm3, in some cases no more than 1.8 g/cm3, in some cases no more than 1.4 g/cm3, in some cases no more than 1.2 g/cm3 and in some cases even less (e.g., no more than 1 g/cm3 or 0.8 g/cm3). The density pi of the material Mi and/or the density p2 of the material M2 may have any other suitable value in other embodiments.
Moreover, in some embodiments, the materials M1, M2 may also be visually contrasting. For instance, in this embodiment, a color of the material Mi may be different from a color of the material M2. As such, the substantial parts 1601-160p of the exterior 27 of the blade holder 28 that are colored differently may be provided by the choice of materials M1, M2 used for the support 82 and the blade-retaining base 80. For example, the color of the material Mi may be darker than the color of the material M2.
In this embodiment, the material Mi is a composite material and the material M2 is a non-composite material (i.e., a material that is not a composite material). In this example, the non-composite material M2 is a non-composite polymeric material.
More particularly, in this embodiment, the composite material Mi is a fiber-matrix composite material that comprises a matrix 90 in which fibers 921-92F are embedded.
The matrix 90 may include any suitable substance. In this embodiment, the matrix 90 is a polymeric matrix. Thus, in this example of implementation, the composite material Mi is a fiber-reinforced plastic (FRP ¨ a.k.a., fiber-reinforced polymer). The polymeric matrix 90 may include any suitable polymeric resin. For instance, in some examples, the polymeric matrix 90 may include a thermoplastic or thermosetting resin, such as epoxy, polyethylene, polypropylene, acrylic, thermoplastic polyurethane (TPU), polyether ether ketone (PEEK) or other polyaryletherketone (PAEK), polyethylene terephthalate (PET), polyvinyl chloride (PVC), poly(methyl methacrylate) (PMMA), polycarbonate, acrylonitrile butadiene styrene (ABS), nylon, polyimide, polysulfone, polyamide-imide, self-reinforcing polyphenylene, polyester, vinyl ester, vinyl ether, polyurethane, cyanate ester, phenolic resin, etc., a hybrid thermosetting-thermoplastic resin, or any other suitable resin. In this embodiment, the polymeric matrix 90 includes an epoxy resin.
The fibers 921-92F may be made of any suitable material. In this embodiment, the fibers 921-92F are carbon fibers. The composite material M1 is thus a carbon-fiber-reinforced plastic in this example of implementation. Any other suitable type of fibers may be used in other embodiments (e.g., polymeric fibers such as aramid fibers (e.g., Kevlar fibers), boron fibers, silicon carbide fibers, metallic fibers, glass fibers, ceramic fibers, etc.).
In this embodiment, the fibers 921-92F are continuous such that they constitute a continuous fiber reinforcement of the composite material M1. For example, in this embodiment, the fibers 921-92F may be provided as layers of continuous fibers (e.g.
pre-preg (i.e., pre-impregnated) layers of fibers held together by an amount of matrix material, which is destined to provide a respective portion of the matrix 90 of the composite material Mi).
In this example, respective ones of the fibers 921-92F are oriented differently. For example, in some embodiments, the fibers 921-92F are arranged in layers stacked upon one another and may extend parallel or at an oblique angle to the longitudinal axis of the blade holder 28. For instance, given ones of the fibers 921-92F in the layers that are stacked may be oriented at 00, +/-45 and +/-90 in an alternating manner. The fibers 921-92F may be arranged in any other suitable way in other examples.
In this embodiment, the polymeric material M2 is a thermoplastic material.
More particularly, in this example, the polymeric material M2 is nylon (polyamide).
The polymeric material M2 may be any other suitable thermoplastic material in other examples (e.g., thermoplastic polyurethane (TPU), acrylonitrile butadiene styrene (ABS), etc.). The polymeric material M2 may be a thermosetting material or any other suitable polymer in other embodiments (e.g., polypropylene, polyethylene (e.g., HDPE), polycarbonate, etc.).
In this embodiment, as shown in Figure 5, a maximal longitudinal dimension LP
(i.e., a maximal dimension in the longitudinal direction of the blade holder 28) of each of the front and rear pillars 84, 86 may be relatively significant. For instance, in some embodiments, a ratio LP/L of the maximal longitudinal dimension LP of the front pillar 84 or the rear pillar 86 over the length L of the blade holder 28 may be at least 0.2, in some cases at least 0.3, and in some cases even more (e.g., 0.4).
With continued reference to Figures 3 to 21, in this embodiment, since it includes the composite material M1 providing greater stiffness, parts of the blade holder 28 that are made of the composite material M1 may be reduced in size in order to reduce the weight of the blade holder 28.
For instance, in this embodiment, the blade holder 28 comprises a void 94 between the front and rear pillars 84, 86 that may be relatively large and thus help to reduce its weight. Notably, in this example, the front and rear pillars 84, 86 are significantly spaced apart in the longitudinal direction of the blade holder 28. A
longitudinal extent V of the void 94 (i.e., a maximal distance between the front and rear pillars 84, 86 in the longitudinal direction of the blade holder 28) is relatively large and a minimal longitudinal dimension C of each of the front and rear pillars 84, 86 (i.e., a minimal dimension in the longitudinal direction of the blade holder 28 of each of the front and rear pillars 84, 86) may be relatively small.
For example, in some embodiments, the longitudinal extent V of the void 94 between the front and rear pillars 84, 86 may be greater than a sum of the minimal longitudinal dimension C of the front pillars 84 and the minimal longitudinal dimension C of the rear pillar 86.

As another example, in some embodiments, the longitudinal extent V of the void between the front and rear pillars 84, 86 may be greater than the minimal longitudinal dimension C of each of the front and rear pillars 84, 86. For instance, in some embodiments, a ratio V/C of the longitudinal extent V of the void 94 between the front and rear pillars 84, 86 over the minimal longitudinal dimension C of each of the front and rear pillars 84, 86 may be at least 1.8, in some cases at least 2, in some cases at least 2.2, and in some cases even greater. This ratio may have any other value in other embodiments.
As yet another example, in some embodiments, a ratio V/L of the longitudinal extent V of the void 94 between the front and rear pillars 84, 86 over the length L
of the blade holder 28 may be at least 0.4, in some cases at least 0.5, in some cases at least 0.6, and in some cases even greater. This ratio may have any other value in other embodiments.
For instance, in this embodiment, the length L of the blade holder 28 may be about 30 cm, the minimal longitudinal dimension C of the front pillar 84 may be about 7 cm, the minimal longitudinal dimension C of the rear pillar 86 may be about 7 cm, and the longitudinal extent V of the void 94 between the front and rear pillars 84, 86 may be about 15 cm for a size 8. The length L of the blade holder 28, the minimal longitudinal dimension C of each of the front and rear pillars 84, 86, and the longitudinal extent V of the void 94 between the front and rear pillars 84, 86 may have any other suitable values in other embodiments.
In this embodiment, each of the front and rear pillars 84, 86 comprises a wall 95 that defines a cavity 96. In this example, the wall 95 is made of the composite material M1 and can be relatively thin. For instance, in some embodiments, a thickness T of the wall 95 may be no more than 5 mm, in some cases no more than 4 mm, in some cases no more than 3 mm, in some cases no more than 2 mm, and in some cases even less. The thickness T of the wall 95 may have any other suitable value in other embodiments.

In this example of implementation, each of the front and rear pillars 84, 86 comprises a top opening 97 that leads to its cavity 96 and faces the skate boot 11 when the blade holder 28 is mounted to the skate boot 11.
Also, in this example of implementation, each of the front and rear pillars 84, 86 comprises a peripheral opening 98 that leads to its cavity 96 such that its cavity 96 is exposed from outside of the skate 10 when the blade holder 28 is mounted to the skate boot 11. That is, each of the front and rear pillars 84, 86 is open peripherally such that its cavity 96 opens up to the outside of the skate 10 when the blade holder 28 is mounted to the skate boot 11. More particularly, in this example of implementation, the peripheral opening 98 of the front pillar 84 and the peripheral opening 98 of the rear pillar 86 face one another.
Therefore, in this embodiment, even though it includes significant parts made of the composite material M1, in view of a reduction in size of these parts and/or use of the polymeric material M2 which is less dense, the weight of the blade holder 28 can be relatively low. For example, in some embodiments, a ratio of the weight of the blade holder 28 over the length L of the blade holder 28 may be no more than 4.3 g/cm, in some cases no more than 4 g/cm, in some cases no more than 3.7 g/cm, in some cases no more than 3.5 g/cm, and in some cases even less (e.g., no more than 3.3 g/cm). For instance, in some embodiments, if the length L of the blade holder 28 is about 30 cm (e.g., for a size 8), the weight of the blade holder 28 may be no more than 130 g, in some cases no more than 120 g, in some cases no more than 110 g, in some cases no more than 105 g, and in some cases even less (e.g., no more than 100 g). The weight of the blade holder 28 may have any other suitable value in other embodiments.
The composite material M1 and the polymeric material M2 making up respective portions of the blade holder 28 may be interconnected in any suitable way.

In this embodiment, the composite material M1 and the polymeric material M2 are mechanically interlocked. That is, the composite material M1 and the polymeric material M2 are in a mechanical interlock relationship in which they are interconnected via a part of the blade holder 28 made of a given one of the composite material M1 and the polymeric material M2 extending into a part of the blade holder 28 made of the other one of the composite material M1 and the polymeric material M2. More specifically, the part of the blade holder 28 made of the given one of the composite material M1 and the polymeric material M2 comprises an interlocking space (e.g., one or more holes, one or more recesses, and/or one or more other hollow areas) into which extends an interlocking portion of the part of the blade holder 28 made of the other one of the composite material M1 and the polymeric material M2.
Moreparticularly, in this embodiment, with additional reference to Figure 28, the upper component 77 of the blade holder 28 made of the composite material M1 and including the front and rear pillars 84, 86 and the thin upper part 69 of the bridge 88 comprises an interlocking space 102 into which extends an interlocking portion of the lower component 78 of the blade holder 28 made of the polymeric material M2 and including the major part 63 of the blade-retaining base 80. In this example, the interlocking space 102 of the upper component 77 of the blade holder 28 made of the composite material M1 comprises a plurality of holes 1061-106H (e.g., which may have been pre-molded or drilled) and the interlocking portion 104 of the lower component 78 of the blade holder 28 made of the polymeric material M2 comprises a plurality of elements 1081-108H that extend into respective ones of the holes 106i-106H to interlock the composite material M1 and the polymeric material M2 together.
In this example of implementation, the blade holder 28 is manufactured using an overmolding process in which the polymeric material M2 is overmolded onto the composite material M1 to create an overmolded joint 112 between the polymeric material M2 and the composite material M1. More particularly, during the overmolding process, the polymeric material M2 flows into the holes 1061-106H of the upper component 77 of the blade holder 28 made of the composite material M1 where it is captured to mechanically interlock the polymeric material M2 and composite material M1 at the joint 112. In some cases, the thermoplastic material M2 and the matrix 90 of the composite material M1 may enhance retention of the materials M1, M2 together (e.g., by creating a chemical bond between them).
More particularly, in this example of implementation, the upper component 77 of the blade holder 28 made of the composite material M1 may be manufactured by providing a plurality of layers of fibers, which are destined to provide the fibers 92i-92F of the composite material M1, onto one another on a supporting structure which is then placed in a mold to consolidate the composite material M1. In this embodiment, each of these layers of fibers is provided as a pre-preg (i.e., pre-impregnated) layer of fibers held together by an amount of matrix material, which is destined to provide a respective portion of the matrix 90 of the composite material M1. The supporting structure onto which the pre-preg layers of fibers are layered may be implemented in any suitable manner (e.g., one or more silicone mold parts, one or more inflatable bladders, etc.). In other embodiments, the matrix 90 of the composite material M1 may be provided separately from (e.g., injected onto) the layers of fibers. The holes 1061-106H for eventual interlocking of the polymeric material M2 may be molded in the mold in which the composite material M1 is consolidated or may be drilled after consolidation of the composite material M1 in the mold. Various other manufacturing techniques may be used to make the upper component 77 of the blade holder 28 made of the composite material M1.
Once the upper component 77 of the blade holder 28 made of the composite material M1 is formed, in this example of implementation, the lower component 78 of the blade holder 28 made of the polymeric material M2 may be manufactured by overmolding the polymeric material M2 onto the composite material M1. For instance, the polymeric material M2 may be injected into a mold in which the upper component 77 of the blade holder 28 is disposed.

At this stage, in some embodiments, as shown in Figure 38, an overlay 182 may be provided on the exterior 27 of the blade holder 28 to provide a particular aesthetic appearance to the blade holder 28. For instance, in this embodiment, the overlay 182 may be provided on the support 82 such that the support 82 comprises the overlay 182.
The overlay 182 may have various different visual characteristics that provide a desired aesthetic appearance to the blade holder 28. For instance, the overlay may comprise a plurality of colors 1841-184N (or in some cases a single color). One or more of the colors 1841-184N of the overlay 182 may be different from the color 137 of the blade-retaining base 80. For example, a color 184, of the overlay 182 may be darker than the color 137 of the blade-retaining base 80. Moreover, in some embodiments, the overlay 182 may exhibit a gradual variation between respective ones of its colors 1841-184N. That is, the overlay 182 may comprise a transition region (not shown) between given ones of the different colors 1841-184N where a given one of the colors 1841-184N of the overlay 182 gradually (i.e., rather than abruptly) changes into an other of the colors 1841-184N of the overlay 182.
In some embodiments, the overlay 182 may comprise a graphic 186. For example, the graphic 186 may be a shape, a symbol, a word, a picture or any other suitable type of visual element.
Moreover, in some embodiments, at least part of the overlay 182 may be transparent. That is, the overlay 182 may comprise a transparent region 188 through which a person can see such that a surface of the material M1 of the support underlying the transparent region 188 is visible through the overlay 182. In such embodiments, the overlay 182 and the surface of the material M1 underlying the transparent region 188 of the overlay 182 form part of the exterior 162 of the support 82. The transparent region 188 may vary in size in accordance with different embodiments. For instance, the transparent region 188 of the overlay 182 may extend throughout substantially an entirety of the overlay 182 such that substantially an entirety of the overlay 182 is transparent. In addition, in some embodiments, the overlay 182 may exhibit a gradual variation in transparency. That is, the overlay 182 may comprise a transition region 190 between its transparent region 188 and a non-transparent region (i.e., a more opaque region) of the overlay 182, the transition region 190 being less transparent than the transparent region 188 but more transparent than the non-transparent region of the overlay 182.
The overlay 182 may be disposed on the support 82 of the blade holder 28 in various ways. For instance, in some embodiments, the overlay 182 may be adhesively bonded to the material M1 of the support 82. For example, in such cases, the overlay 182 may be a sticker. In other embodiments, the overlay 182 may be a decal that is configured to transfer a design (e.g., its colors, graphics, etc.) onto the material M1 of the support 82.
The blade holder 28 can be manufactured using any other suitable process in other embodiments.
In this embodiment, the blade-detachment mechanism 55 of the blade holder 28 to selectively attach and detach the blade 52 to and from the blade holder 28 is disposed in a cavity 130 defined by a wall 132 of the blade-retaining base 80 made of the polymeric material M2. The polymeric material M2 is thus disposed between the blade 52 and the composite material M1. The greater compliance of the polymeric material M2, and possibly its greater ductility, may help to isolate the composite material M1 from the blade 52 and the blade-detachment mechanism 55 and thus reduce a potential for rattling or other vibrations to be transmitted to the composite material M1 (e.g., thereby reducing a potential for local stresses and crack formation in the composite material Mi). The polymeric material M2 may thus serve as a "bumper" between the blade 52 and the composite material M1. In this example, the cavity 130 is contiguous to the cavity 96 defined by the wall 95 of the rear pillar 86 such that an opening 136 links the cavity 130 and the cavity 96 which constitute a common continuous hollow space. In other examples, the cavity 130 may be isolated from the cavity 96 defined by the wall 95 of the rear pillar 86.
The blade 52 comprises an ice-contacting material 140 including an ice-contacting surface 127 for sliding on the ice surface while the skater skates. In this embodiment, the ice-contacting material 140 is a metallic material (e.g., stainless steel). The ice-contacting material 140 may be any other suitable material in other embodiments. Also, in this embodiment, an entirety of the blade 52 is made of the ice-contacting material 140.
The ice skate 10, including the blade holder 28, may be implemented in any other suitable way in other embodiments.
For example, in other embodiments, the substantial parts 1601-160p of the exterior 27 of the blade holder 28 that are colored differently may be arranged in any other suitable manners.
For instance, in some embodiments, as shown in Figure 39, the exterior 27 of the blade holder 28 may comprise a checkered pattern 192. Notably, in some embodiments, the checkered pattern 192 may extend over a substantial part of the exterior 27 of the blade holder 28 but does not extend over another substantial part of the exterior 27of the blade holder 28.
For example, in this embodiment, the exterior 162 of the support 82 comprises the checkered pattern 192. The checkered pattern 192 may extend over a limited portion of the exterior 162 of the support 82 or, in some cases, may extend over a significant portion of the exterior 162 of the support 82. For instance, in some cases, the checkered pattern 192 may occupy at least 10% of the exterior 162 of the support 82, in some cases at least 25% of the exterior 162 of the support 82, in some cases at least 50% of the exterior 162 of the support 82 (i.e., at least the majority of the exterior 162 of the support 82), in some cases at least 75% of the exterior 162 of the support 82, in some cases at least 90% of the exterior 162 of the support 82, or in some cases even more (e.g., substantially an entirety of the exterior 162 of the support 82).
The checkered pattern 192 may be provided on the exterior 162 of the support 62 in various ways. For instance, in some embodiments, the checkered pattern 192 may be defined by intersecting elements 1941-194N of the composite material M1.
For example, the intersecting elements 1941-194N of the composite material M1 may be elements of tape of the composite material M1 that are woven, interlaced or otherwise intersect one another.
In contrast, in this embodiment, at least part of the exterior 164 of the blade-retaining base 80 may be free of checkering. That is, at least part of the exterior 164 of the blade-retaining base 80 may not comprise a checkered pattern like the checkered pattern 192. In this example, at least a majority (i.e., a majority or an entirety) of the exterior 164 of the blade-retaining base 80 is free of checkering. More particularly, in this example, substantially the entirety of the exterior 164 of the blade-retaining base 80 is free of checkering.
Various other configurations of the blade holder 28 may be possible in other embodiments.
Examples of other possible configurations are shown in Figures 40 to 47. For instance, in one example, as shown in Figure 40, a darker color CLD of the exterior 162 of the support 82 may be provided at a top portion of each of the front and rear pillars 84, 86 and at a bottom portion of the support 82 (e.g., at an interface with the color 137 of the blade-retaining base 80). A lighter color CLL, for example similar to the color 137 of the blade-retaining base 80, may be provided at an intermediate portion of the support 82 between the top portions of the pillars 84, 86 and the bottom portion of the support 82. In another example, as shown in Figure 41, the top portion of each of the front and rear pillars 84, 86 may be provided with the lighter color CLL while the darker color CLD of the exterior 162 of the support 82 may be provided at the bottom portion of the support 82 exclusively. In both embodiments show in Figures 40 and 41, a transition region may be provided between the darker color OLD of the exterior 162 of the support 82 and the lighter color CLL of the exterior 162 of the support 82 such that the exterior 162 of the support 82 may exhibit a gradual variation between respective ones of its colors CLi-CLN.
As yet another example, as shown in Figure 42, the darker color OLD of the exterior 162 of the support 82 may not necessarily be above or below the lighter color CLL of the exterior 162 of the support 82. For instance, in this example, the darker color OLD is positioned rearwardly of the lighter color CLL such that a transition region between the darker color OLD and the lighter color CLL provides a gradual variation between the darker and the lighter colors OLD, CLL in the longitudinal direction of the blade holder 28. Moreover, in this example, the lighter color CLL extends along at least a majority of the front pillar 84. Alternatively or additionally, in other examples, the lighter color CLL may extend along at least a majority of the rear pillar 86.
In the example of Figure 43, the darker color OLD of the exterior 162 of the support 82 occupies the bottom portion of the support 82 and the exterior 162 of the support 82 has no transition region between the darker color OLD and the lighter color CLL
and therefore there is an abrupt variation between the colors OLD, CLL of the exterior 162 of the support 82. In the examples of Figures 42 and 43, the darker color OLD
has a greater extent in the rear pillar 86 than in the front pillar 84. That is, the darker color OLD extends along a greater portion of the rear pillar 86 than a portion of the front pillar 84.
As yet another example, as shown in Figure 44, the darker color OLD of the exterior 162 of the support 82 may be provided at the top portion of each of the front and rear pillars 84, 86 and at the bottom portion of the support 84, while the intermediate portion of the support 82 between the top portion of the pillars 84, 86 and the bottom portion of the support 82 is provided with the lighter color CLL. As such, in this example, each of the front and rear pillars 84, 86 comprises a pair of regions that are not continuous to one another and that are provided with the darker color CLD.
As yet another example, as shown in Figure 45, the darker color CLD may occupy at least a majority of the exterior 162 of the support 82. For example, a lighter color (e.g., similar to the color 137 of the blade-retaining base 80) may occupy a small top portion of the front and rear pillars 84, 86 while a remainder of the support 82 is provided with the darker color CLD.
As yet another example, as shown in Figure 46, the darker color CLD of the exterior 162 of the support 82 may extend mainly along a region adjacent the void 94 of the blade holder 28. For instance, a rear portion of the rear pillar 86 and a front portion of the front pillar 84 may be provided with a lighter color (e.g., similar to the color 137 of the blade-retaining base 80).
In the example shown in Figure 47, a majority of the exterior 141 of the rear pillar 86 has the darker color CLD while about half the exterior 139 of the front pillar has the darker color OLD.
In other embodiments, the blade holder 28 may have any other suitable shape.
For instance, in other embodiments, the support 82 and/or the blade-retaining base 80 may be shaped in various other ways (e.g., the front and rear pillars 84, 86 may be shaped differently; the blade-retaining base 80 may have more, fewer, or no apertures such as the apertures 811-814; etc). As an example, Figure 48 shows an embodiment in which the front and rear pillars 84, 86 are open only at their top opening 97 (i.e., they lack any peripheral opening such as the peripheral opening 98). As another example, Figure 50 shows an embodiment in which in which the blade-retaining base 80 has five apertures such as the apertures 811-814. As yet another example, Figure 49 shows an embodiment in which the blade-retaining base 80 has no apertures such as the apertures 811-814. As yet another example, Figure 52 shows an embodiment in which the support 82 and the blade-retaining base 80 are shaped differently than in embodiments considered above. For instance, the front and rear pillars 84, 86 of the support 82 may be shaped differently such that the void 94 between the front and rear pillars 84, 86 is shaped differently (e.g., has a more square, rounded, or polygonal shape). At least the majority of the exterior 162 of the support 82 is colored differently than at least the majority of the exterior 164 of the blade-retaining base 80.
As mentioned above, in some situations, blade holders which are too dark may have a visual and/or psychological effect on skaters that may sometimes make them feel as though they are skating slower than they are in reality. In that context, the blade holder 28 may be configured to provide the exterior 162 of the support 82 with a darker portion while ensuring that the skater cannot observe or can observe a limited portion of the darker portion of the exterior 162 of the support 82 while the skater is skating. For instance, with reference to Figure 53, in some embodiments, the blade holder 28 may be configured such that, when the skate 10 is at an angle a relative to the ice surface 5, at least a majority of the darker portion of the exterior 162 of the support 82 is not visible when viewed perpendicularly to the ice surface 5. In some cases, the angle a may be at least 15 , in some cases at least 20 , in some cases 30 , in some cases 45 and in some cases even more. In other embodiments, the blade holder 28 may not be configured as such.
In other embodiments, the composite material M1 and the polymeric material M2 of the blade holder 28 may be interconnected in any other suitable way.
For example, in some embodiments, as shown in Figures 50 and 51, the upper component 77 of the blade holder 28 made of the composite material M1 comprises a plurality of projections 1531,1532 that project towards the lower component 78 of the blade holder 28 made of the polymeric material M2 and that include part of the interlocking space 102 into which extends the interlocking portion 104 of the lower component 78 of the blade holder 28. In this embodiment, each of the projections 1531,1532 is a flap, the part of the interlocking space 102 of the upper component 77 of the blade holder 28 formed by each of the flaps 1531,1532 comprises a plurality of holes 1551,1554 (e.g., which may have been pre-molded or drilled), and the interlocking portion 104 of the lower component 78 of the blade holder 28 comprises a plurality of elements 1681-1688 that extend into respective ones of the holes 1551-1554 of each of the flaps 1531,1532 to interlock the composite material M1 and the polymeric material M2 together. Thus, in this embodiment, the holes 1061-106H
and the holes 1551-1554 of the interlocking space 102 of the upper component 77 of the blade holder 28 are oriented differently such that the elements 1081-108H and the elements 1681-1688 of the interlocking portion 104 of the lower component 78 of the blade holder 28 extend transversally to one another (e.g., in this case, the elements 1081-108H extend into the holes 1061-106H generally vertically and the elements 1681-1688 extend into the holes 1551-1554 generally horizontally). In some cases, this may help to further enhance mechanical interlocking of the composite material M1 and the polymeric material M2.
As another example, in some embodiments, as shown in Figure 29, instead of or in addition to the upper component 77 of the blade holder 28 made of the composite material M1 comprising the interlocking space 102 into which extends the interlocking portion 104 of the lower component 78 of the blade holder 28 made of the polymeric material M2, the lower component 78 of the blade holder 28 made of the polymeric material M2 may comprise an interlocking space 116 into which extends an interlocking portion 118 of the upper component 77 of the blade holder 28 made of the composite material M1. For instance, in this embodiment, the interlocking space 116 of the lower component 78 of the blade holder 28 made of the polymeric material M2 comprises a plurality of holes 1201-120j (e.g., which may have been pre-molded or drilled) and the interlocking portion 118 of the upper component 77 of the blade holder 28 made of the composite material M1 comprises a plurality of elements 1221-122j that extend into respective ones of the holes 1201-120j to interlock the composite material M1 and the polymeric material M2 together.
In this example, the thermoplastic resin of the matrix 90 of the composite material M1 when provided (e.g., injected) flows into the holes 1201-120j defined by the polymeric material M2 to create the elements 1221-122j that interlock the composite material M1 and the polymeric material M2 together.
As another example, in some embodiments, as shown in Figure 30, instead of or in addition to the composite material M1 and the polymeric material M2 being mechanically interlocked, the composite material M1 and the polymeric material may be adhesively bonded by an adhesive 124. The adhesive 124 may be an epoxy-based adhesive, a polyurethane-based adhesive, a methacrylate adhesive, a methyl methacrylate adhesive, or any other suitable adhesive for bonding the composite material M1 and the polymeric material M2.
As another example, in some embodiments, as shown in Figure 31, instead of or in addition to the composite material M1 and the polymeric material M2 being mechanically interlocked and/or adhesively bonded, the composite material M1 and the polymeric material M2 may be fastened using one or more fasteners 128.
Each fastener 128 may be a rivet, a screw, a bolt, or any other suitable mechanical fastener While in embodiments considered above the different materials M1, M2 making up respective parts of the blade holder 28 include a composite material and a non-composite polymeric material, the different materials M1, M2 may include any other suitable combination of materials in other embodiments. For example, in some embodiments, the material M1 may be a composite material and the material M2 may be a different composite material (e.g., less stiff than the composite material M1, by including fewer and/or less rigid fibers in its matrix and/or having its matrix more compliant than the composite material Mi). For instance, in some embodiments, the composite material M1 may include continuous fibers (e.g., pre-preg layers of fibers) providing a continuous fiber reinforcement as discussed above, while the composite material M2 may include discontinuous (e.g., chopped) fibers randomly dispersed within its matrix. For example, in some cases, the composite material M2 may include a nylon matrix in which are dispersed chopped fibers (e.g., 10% or 20%

chopped fibers) such as carbon or aramid fibers, which may also enhance abrasion resistance). Thus, in some embodiments, the composite material M2 may include a polymeric matrix (e.g., nylon) that is reinforced with fibers.
Also, while in embodiments considered above there are two different materials M1, M2 making up respective parts of the blade holder 28, the material distribution profile of the blade holder 28 may include three or more different materials making up respective parts of the blade holder 28 such as described above in relation to the materials M1, M2.
In other embodiments, the blade holder 28 may retain the blade 52 in any other suitable way. For instance, instead of being selectively detachable and removable from and attachable to the blade holder 28, in other embodiments, the blade 52 may be permanently affixed to the blade holder 28 (i.e., not intended to be detached and removed from the blade holder 28). As an example, in some embodiments, as shown in Figures 30 and 31, the blade holder 28 may retain the blade 52 using an adhesive 172 and/or one or more fasteners 175. For instance, in some embodiments, as shown in Figure 32, the recess 76 of the blade holder 28 may receive the upper part of the blade 52 that is retained by the adhesive 172.
The adhesive 172 may be an epoxy-based adhesive, a polyurethane-based adhesive, or any suitable adhesive. In some embodiments, instead of or in addition to using an adhesive, as shown in Figure 33, the recess 76 of the blade holder 28 may receive the upper part of the blade 52 that is retained by the one or more fasteners 175.
Each fastener 175 may be a rivet, a screw, a bolt, or any other suitable mechanical fastener. Alternatively or additionally, in some embodiments, as shown in Figure 34, the blade-retention portion 75 of the blade holder 28 may extend into a recess 181 of the upper part of the blade 52 to retain the blade 52 using the adhesive 172 and/or the one or more fasteners 175. For instance, in some cases, the blade-retention portion 75 of the blade holder 28 may comprise a projection 188 extending into the recess 181 of the blade 52. As another example, in some embodiments, as shown in Figure 35, the blade 52 and the blade-retaining base 80 of the blade holder 28 may be mechanically interlocked via an interlocking portion 191 of one of the blade-retaining base 80 and the blade 52 that extends into an interlocking void 193 of the other one of the blade-retaining base 80 and the blade 52. For instance, in some cases, the blade 52 can be positioned in a mold used for molding the blade holder 28 such that, during molding, the interlocking portion 191 of the blade-retaining base 80 flows into the interlocking void 193 of the blade 52 (i.e., the blade holder 28 is overmolded onto the blade 52).
The blade 52 may be implemented in any other suitable way in other embodiments.
For example, in some embodiments, as shown in Figures 36 and 37, the blade 52 may comprise a runner 145 that is made of the ice-contacting material 140 and includes the ice-contacting surface 127 and a body 148 connected to the runner and made of a material 150 different from the ice-contacting material 140. The runner 145 and the body 148 of the blade 52 may be retained together in any suitable way. For example, in some cases, the runner 145 may be adhesively bonded to the body 148 using an adhesive. As another example, in addition to or instead of being adhesively bonded, the runner 145 and the body 148 may be fastened using one or more fasteners (e.g., rivets, screws, bolts, etc.). As yet another example, the runner 145 and the body 148 may be mechanically interlocked by an interlocking portion of one of the runner 145 and the body 148 that extends into an interlocking space (e.g., one or more holes, one or more recesses, and/or one or more other hollow areas) of the other one of the runner 145 and the body 148 (e.g., the body 148 may be overmolded onto the runner 145).
