SKATE-SKIS Russian patent published in 2014 - IPC A63C5/00 

FIELD: personal use articles.

SUBSTANCE: skate-skis contain gliding surfaces designed in the form of replaceable profiles mounted on the skate-ski so that to enable the profiles relocation along the skate-skis length, a stock part with a friction overlay mounted thereon so that to enable contact with the race track as a result of plane-parallel movement within the vertical plane of the stock part induced by the dynamic load of a leg push; a support pad mounted on the stock part and designed in the form of a swinging arm at the free end whereof a crank is pivotally connected, the other end interacting with the slider installed on the stock part with linear movement regulation. The replaceable profiles are designed in the form of stabilising devices, each of them containing two bodies turning relative to each other by means of the axle installed in the holes in the outer bodies walls. On the shelf of the inner body the skate-ski is mounted while the bottom side of the outer body is designed in the form of two coaxially resiliently deformable gliding surfaces so that to enable the race track unevenness and relief. The gliding profiles are equipped with balancing devices designed in the form of springs so that to enable tensioning force regulation and pivotally interacting with the profiles axis pin via one end and with the gliding profiles consoles - via the other.

EFFECT: increased operational reliability.
