Abstract
In a tread for a power-driven ski type of device having a chain with a plurality of spaced propulsion cleats, an outwardly protruding propulsion cleat, constructed with a venting passage and with resiliency to enable it to bend and thereby withstand the dynamic forces associated with its protruding construction, and to vent snow which is continuously trapped between itself and the sprockets, when the cleat swings over and around these sprockets.
Claims10
In a power driven ski type of a device using a tread of the type having an endless linked chain adapted to circulate over a sprocket and a plurality of spaced propulsion cleats, each of said cleats having a snow engaging side opposite from a sprocket engaging side, a propulsion cleat comprising in combination;
- a cleat attachment link adapted to form a part of said chain and having an attachment plate, and
- a snow engaging section made of a resilient material attached to said attachment plate and having a roof-plate integral with a protruding blade,
- wherein said protruding blade is resiliently connected to said attachment link, for preventing the creation of a destructive shock by said protruding blade between said attachment link to said sprocket and said power driven ski type of a device, when said protruding blade accelerates and decelerates over said sprocket.
A tread having a plurality of cleats attached to a chain, for a power driven ski type of a device, comprising in combination:
- said chain, adapted to circulate over a sprocket, and containing a plurality of cleat's attachment links, each of said links having an attachment plate,
- a snow engaging section made of a resilient material attached to said attachment plate and having a roof-plate integral with a protruding blade,
- wherein said protruding blade is resiliently connected to said attachment link, for preventing the creation of a destructive shock by said protruding blade between said attachment link to said sprocket and said power driven ski type of a device, when said protruding blade accelerates and decelerates over said sprocket.
