Abstract: A skate and a replaceable skate blade are disclosed. The skate includes a boot and a blade assembly with a blade holder and a blade removable mounted to the holder. A locking pin is displaceable relative the blade holder between a blade locking position in which a tip of the locking pin is in engagement with the blade and a blade releasing position in which the tip of the locking pin is disengaged from the blade. A pin actuator is engageable by a user for translating the pin actuator along a longitudinal axis of the locking pin, wherein translation of the pin actuator induces translation of the locking pin along the longitudinal axis from the blade locking position to the blade releasing position. A biasing element reacts against the pin actuator and biasing the locking pin in the blade locking position.

Abstract: A sport helmet has an outer shell including a first shell and a second shell movable relative to the first shell; levers hingedly connected to the first shell on left and right sides of the sport helmet for adjustably securing the first and second shells together; and finger-engageable locking actuators for selectively allowing movement of the levers from the engaged position to the disengaged position, the finger-engageable locking actuators being engaged to anchoring projections receivable within anchoring apertures, the finger-engageable locking actuators movable between a locked position and an unlocked position, wherein in the locked position movements of the levers relative to the first shell are limited via the anchoring projections, and wherein in the unlocked position the anchoring projections are disengaged from the anchoring apertures such that the levers are pivotable between the engaged position and the disengaged position.

Abstract: A runner for an ice skate. The runner extends along a longitudinal axis between a front end and an opposed rear end. The runner is entirely metal and has a height extending between an ice-contacting portion for engaging an ice surface and an opposed upper portion. The runner has a datum runner thickness defined between outer and inner side surfaces of the runner. The runner has one or more regions of reduced thickness that are recessed inwardly from one or both of the outer and inner surfaces. The regions have a local thickness being less than the datum runner thickness. An ice skate and method of making a runner for an ice skate are also disclosed.

Abstract: A blade holder assembly for a skate including a blade holder having an elongated groove defined in a bottom surface, and a recess extending upwardly therefrom in alignment with a pedestal, for engagement with a blade. The pedestal has an internal cavity defined therein separate and spaced from the elongated groove and the recess. A locking arm is engaged to the pedestal and movable between a locked position and an unlocked position. The locking arm has an engagement end protruding into the recess through an opening defined in a wall of the pedestal. A greater portion of the engagement end protrudes into the recess in the locked position than in the unlocked position. At least a major part of the locking arm, including the engagement end, remains outside of the internal cavity of the pedestal in the locked and unlocked positions. A blade assembly is also discussed.

Abstract: Shock-absorbing helmet liners may be releasably locked to helmet shells using mechanical fasteners.

Abstract: A carrying device uses a folding structural frame covered by a shell. The frame is configured with two rigid members, which are joined together by two pivotable joints. A two-part base piece attaches to the frame and creates a structural bottom for the bag, with the base supporting articles placed inside of the bag. The frame and base create support that enables the bag to stand upright on a flat surface. The shell is made from a soft, flexible fabric material. The assembly is capable of folding to a substantially flat position, with the frame members moving relative to one another around the pivotable joints, and the base folding in half and becoming substantially co-planar with the frame. A strap attaches to the device in multiple configurations, allowing the device to be carried in different ways.
