SKATES-SKIS Russian patent published in 2014 - IPC A63C5/06 

FIELD: transport.

SUBSTANCE: these appliances comprises sliding surfaces composed by replaceable sections secured thereat to allow their rearrangement over the length, block part with friction plate secured therein to contact with running track as the result of block part elastic deformation from dynamic load at leg push. It has bearing plate secured at block part composed of the link. Crank is swivelled on free end of the latter to interact with the slider by opposite end, said slider being fitted on block part with linear displacement adjustment. Replaceable sections are composed of stabilising devices. Each of the latter comprises two channel-like cases swivelling relative to each other on axle fitted at outer case walls. Skate-ski is secured at inner case flange. Outer case bottom part is composed of two cantilever elastically deformable sliding surfaces to trace the running track irregularities and relief. Sliding channels are equipped with balancing devices. The latter are composed of springs that allow tension adjustment to interact with channel swing axle by one end. Opposite end interacts with sliding channel supports. Note here that inner channel-like case comprises devices to adjust and control road clearance. Said skates-skis are equipped with the device to carry, transfer, store, conserve the skates-skis pairs and to vary and damp the slider.

EFFECT: higher operating reliability.
