Abstract: A blade for an ice skate (e.g., for playing hockey). The ice skate comprises a skate boot for receiving a foot of a user and a blade holder for holding the blade. The blade may be designed to be lightweight yet strong and possibly provide other performance benefits to the user, including by being made of different materials (e.g., at least three different materials) that are strategically arranged and secured to one another.

Abstract: A 3D printed thermal expansion structure includes a thermoplastic material and a thermal expansion material, wherein the thermoplastic material is in a range from 50 to 90 wt % based on a weight of the 3D printed thermal expansion structure, and the thermal expansion material is in a range from 10 to 50 wt % based on the weight of the 3D printed thermal expansion structure. The thermoplastic material and the thermal expansion material are mixed to form a mixed material, and the mixed material is utilized by a 3D printing apparatus to form a solid object, and the solid object is heated to form the 3D printed thermal expansion structure. A manufacturing method of a 3D printed thermal expansion structure is provided herein.

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: 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. 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: A skate boot comprising an outer shell including medial and lateral side portions for facing the medial and lateral sides of the foot. Each of the medial and lateral side portions has an upper edge. The skate boot also comprises a lace member mounted to either of the upper edges of the medial and lateral side portions. The lace member has at least one opening for receiving an insert. The lace member has a first flexion mode when no insert is received in the at least one opening and a second flexion mode when the insert is received in the at least one opening. The second flexion mode is different from the first flexion mode.

Abstract: A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

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 and a support extending upwardly from the blade-retaining base to interconnect the blade holder and the skate boot. Visual characteristics of the blade holder may enhance 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.). The blade holder may be lightweight and/or provide other performance benefits to the skater.

Abstract: A skate boot comprising an outer shell including medial and lateral side portions for facing the medial and lateral sides of the foot. Each of the medial and lateral side portions has an upper edge. The skate boot also comprises a lace member mounted to either of the upper edges of the medial and lateral side portions.
