Abstract: A pin mount system for releasably mounting a sports net to a ground surface, for example a hockey net to an ice surface. The sports net includes at least one post having an end. The pin mount system includes: a pin having a proximal end and a distal end, the proximal end for positioning within the post, a resilient member such as a spring coil in compression to normally exert an extensive force to the pin to extend the distal end of the pin past the end of the post, and a handle operably connected to the pin to retract the pin against the resilient member. The pin is releasable from the ground surface in response to an amount of force applied to the sports net, and the sports net stays in place when minor force is applied, for example.

Abstract: A replaceable blade system for ice skates is provided with a rotary retention latch located within an enclosed chamber of the holder of the skate. The rotary retention latch is configured with a release lever that is adapted to be accessed through an aesthetic aperture in the holder.

Abstract: A replaceable blade ice skate (9) comprising a holder (2), a blade system having at least one blade engagement portion (11) and a blade (4, 52), at least one attachment device (5) mounted to the holder for movement between a blade securing position and a blade releasing position. The attachment device having an attachment engagement portion (6), wherein the blade system is retained in the holder via the blade engagement portion detachably mating with the attachment engagement portion when the attachment device is in the blade securing position. The blade system further comprising a downward facing rocker (3) and a flexible replaceable blade (4) which conforms to the first defined curvature of the rocker when mounted thereon.
