Abstract: A hockey-stick blade includes a heel region, a toe region spaced longitudinally from the heel region, and a mid-region located between the heel region and the toe region. The toe region includes one or more reinforcing elements, optionally of different lengths, located at different vertical positions within the toe region. The blade further includes a hosel that optionally is tailored to substantially match the strength and stiffness characteristics of an attached or integral hockey stick shaft. The mid-region of the blade exhibits improved feel and flexibility characteristics due to the increased stiffness in the toe region.

The U-shaped outer member has an elongated blade-supporting base and front and rear pillars that are spaced apart in a longitudinal direction of the blade holder. At least part of the elongated blade-supporting base, front pillar and rear pillar is made of a composite material such as a fiber-matrix composite material. The ice skate also has a blade comprising a runner and a body made of composite material with a matrix and a plurality of fibers embedded in the matrix.

Abstract: Protective headgear that is wearable on a head of a user and may be configured to provide impact protection and contaminant protection. The protective headgear may comprise a helmet configured to protect the user's head against impacts and a contaminant blocker configured to protect against contaminants (e.g., infectants), such as pathogens (e.g., viruses, bacteria, or other microorganisms) or other biohazards, chemical hazards, or other hazardous substances, transmittable to or from the user (e.g. as part of spatter, an aerosol, or other droplets). The helmet and the contaminant blocker may be configured to connect or otherwise interact with one another to be usable together. This may facilitate their use to enhance protection of the user and/or an environment of the user, while maintaining performance of the user, including by providing breathability, being spatter proof, ensuring proper vision, being antifogging, being customizable, and/or having other desirable attributes.

Abstract: A helmet for protecting a head of a wearer, such as a hockey, lacrosse, football or other sports player. The helmet may have various features to protect the wearer's head against impacts, such as linear impacts and rotational impacts. For example, pads of the helmet may be movable relative to one another in response to an impact on the helmet. The helmet may comprise a frame comprising a plurality of frame members carrying respective ones of the pads and configured to move relative to one another in response to the impact to allow relative movement of the pads.

Abstract: Hockey goalkeeper leg pads wearable on legs of a hockey goalkeeper to protect the legs, in which protective parts (e.g., pad members) of the hockey goalkeeper leg pads are adjustable to adjust how the hockey goalkeeper leg pads fit on the legs, and their adjustability is provided in a way that may be relatively light, easy to use, and simple to manufacture.

Abstract: A construct for a hockey skate outsole formed from layers of sheet molding compound material. The sheet molding compound material may be manufactured to have shorter average fiber lengths with random orientation in order to enhance the mechanical properties of the formed hockey skate outsole.

Abstract: A blade holder for an ice skate (e.g., for playing hockey). The ice skate comprises a skate boot for receiving a foot of a skater. The blade holder comprises a blade-retaining base to retain a blade. The blade-retaining base comprises a first material (e.g., a non-composite polymeric material). The blade holder comprises a support extending upwardly from the blade-retaining base to interconnect the blade holder and the skate boot. The support comprises a second material (e.g., a composite material) different from (e.g., stiffer than) the first material.

Abstract: Articles of sports equipment, such as striking implements (e.g., sticks) and wearable articles (e.g., skates, helmets) for playing hockey or other activities, in which at least one of the characteristics (e.g., stiffness) of the articles of sports equipment is adaptable and can be altered during use of the sports equipment, such as by comprising an alterable component coupled to a controller, by comprising an alterable component that is autonomously alterable, and/or by an alterable component that can be altered in response to a command of a remote device.

Abstract: Methods and systems for customizing wearable equipment such as athletic equipment, including ice skates and protective equipment such as masks. For example, a hockey goaltender mask may comprise a shell a liner attached to the shell, the liner being customized for a face of a user. The liner may be produced using a customized mold. Such customized mold may include a base mold and at least one attachment attached to the base mold; wherein each of the at least one attachment is characterized by at least one feature determined based on computer processing of data representative of the face of the user.

Abstract: A goalie skate for a hockey goalkeeper. The goalie skate may comprise a skate boot for receiving a foot of the hockey goalkeeper, a blade for contacting ice, and a blade holder between the skate boot and the blade. The skate boot comprises an outer shell comprising a synthetic material. The goalie skate may be cowlingless.

Abstract: A skate boot comprising an outer shell with 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 comprising a recess for receiving an insert. 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 is different from the first flexion mode.

Abstract: An ice skate comprising a blade holder having U-shaped inner and outer members that are spaced apart to define a hollow space therebetween. The U-shaped outer member has an elongated blade-supporting base and front and rear pillars that are spaced apart in a longitudinal direction of the blade holder. At least part of the elongated blade-supporting base, front pillar and rear pillar is made of a composite material such as a fiber-matrix composite material.

Abstract: A sporting implement, such as a blade or shaft for a hockey stick, may include a boron-enhanced fiber material configured to increase the strength and reduce the weight of the structure. This boron-enhanced material may form all or a portion of the sporting implement.

Abstract: A hockey-stick includes a blade and a shaft. The blade includes a heel region, a toe region spaced longitudinally from the heel region, and a mid-region located between the heel region and the toe region. The blade optionally also includes a hosel to which the shaft is attached. One or more tuning rods or similar structures are positioned in the blade to increase the blade's stiffness to substantially match the stiffness of the shaft. The tuning rods are optionally located in the mid-region of the blade and may extend into the hosel and, in some cases, into the shaft or the toe region.

Abstract: A construct for a hockey stick blade and paddle structure having a spine that protrudes from a back face and provides structural rigidity, as well as recessed areas that reduce the mass of the paddle structure.

Abstract: A construct for a hockey stick that includes a shaft having with variable cross-sectional geometry. The shaft may include one or more portions with pentagonal and heptagonal cross-sections that increase the bending stiffness of the hockey stick shaft.

Abstract: A skate (e.g., an ice skate) or other footwear for a user, in which a skate boot or other foot-receiving structure for receiving a foot of the user may be configured to enhance power transfer of the user (e.g., for push-off and skating straight), agility of the user (e.g., for turns), and/or other aspects of performance of the user, such as by comprising a sole region that is configured to be disposed under the user's foot and includes different materials strategically distributed (e.g., in a longitudinal direction of the skate boot or other foot-receiving structure) or otherwise implements these enhancements.
