ABSTRACT:
A snowshoe includes a perimeter frame carrying sheet-type floatation and having a hinge rod supported transversely of the frame. A bearing sleeve or bushing is disposed about the hinge rod and a cooperates therewith to enable snap-on assembly and release of a claw plate having a binding supported thereon, thereby enabling interchanging of claw plates and bindings for a particular snowshoe frame and decking. The hinge rod and bushing cooperate to vary the frictional resistance to relative rotation between the claw plate and hinge rod, and thereby provide a shock absorber effect. Various features of the claw plate enable adjustment of the frictional resistance to rotation of the claw plate about the hinge rod to accommodate different uses of the snowshoe and different characteristics of the user. Other features include an improved arrangement for securing the outer marginal edge of the sheet-type decking or floatation material to the frame.
