Abstract: A snow shoe (1) has a longitudinal support structure or ridge (18) surrounded by a screen (4). The longitudinal ridge defines a plurality of apertures (180a, 180b, 180c), an upper surface (20), and lower projecting surfaces (21a, 21b, 25a, 25b). A detachable blade or knife (30) includes a central projection (33) which extends through the aperture in the central ridge and mates with portions of the lower ridge which define the aperture. The blade includes a rearward extending tab (330a) which extends through the aperture and engages the upper wall of the central ridge. A rivet or other pivot pin (34) pivotally holds a bar (35) to the upper projection of the blade. When the upper projection is received in the aperture, the bar pivots to engage the upper surface of the central ridge. A plurality of knives or teeth (36a, 36b, 36c, 36d, 37a, 37b, 37c, 37d) extend downward to engage ice or packed snow.

Abstract: A snowshoe (1) has a peripheral frame (2). A deck (4) extends across an interior of the peripheral frame and supports a binding (5) for retaining the boot of the user. The snowshoe has horizontal surfaces for supporting the snowshoe and the user on top of the snow and downward depending on traction members (3a, 3b, 50a, 50b) for engaging the snow to facilitate walking without slipping. The traction members are preferably disposed vertically and extend downward below a horizontal plane (H) of the deck. The traction members have regions of reduced height (100, 100a, 100b, 100c, 100d, 100e, 100f) relative to a forward portion (7a) of the traction members or the rearward portion (7c) of the traction members in a central zone (B) aligned with the region which receives and holds the user's boot (6).

Abstract: A snow shoe (1) has a peripheral frame (2) which defines an interior zone or screen (8). A retention device (3) retains a shoe (4) of a user on the snow shoe. The retention device includes a pivoting plate (7) which is articulated on the screen around a transverse pivoting axle (9), a front strap (10), arranged on the pivoting plate, and a positioning and a control mechanism which permits modification of the longitudinal position of the user's shoe. Specifically, the retention device permits positioning of the front or rear end of the shoe relative to the pivoting axle (7), or of the pivoting axle relative to the screen (8).

Abstract: A snow shoe (1) has a peripheral frame (2) which defines an interior zone. A central part (14) is disposed centrally in the open zone to receive a binding (5). A plurality of support walls (40) extend transversely between the central part and the peripheral frame. The support walls are downwardly concave, having a central portion (40c) disposed between front portions (40a) and rear portions (40b). Forward downward extending edges (42a) extend downward from the front wall portion and rearward downward extending edges (42b) extend downward from the rear wall portions.
