发明名称 Snowshoe
摘要 A lightweight snowshoe is disclosed utilizing longitudinally extending spaced apart frame members having a cross-section in the form of a rectangle, preferably with concave sidewalls and end walls. Spaced countersunk openings are provided along the length of the frame member to receive webbing which criss-crosses the area between the frame members. The frame members are flexible along their minor axes but substantially rigid along their major axes. When the weight of the wearer is imposed on the webbing, the flexing of the frame members allows the webbing to sag downwardly to contact the snow and form a traction surface to prevent forward or backward slippage. When the weight on the webbing is relieved the frame members spring back to their original position. The lower edges of the frame members have relatively sharp edges to penetrate the snow and prevent side slippage when traversing sloping terrain.
