Abstract:
A pole for skiing and trekking comprising an axially elongated shaft and a basket having an annular hub detachably mounted on said shaft adjacent one end of said shaft, wherein a bayonet connection is provided between said shaft and said basket, said bayonet connection comprising a first grooved profile disposed internally of said hub and having axially extending grooves alternating with axially extending radial projections and a second grooved profile on said shaft having axially extending grooves alternating with axially extending radial projections extending between axially spaced first and second shoulders on said shaft, said first shoulder closest to said one end of said shaft having circumferential interruptions aligned with respective grooves in said shaft to allow passage of corresponding radial projections on said hub into said grooves on said shaft upon axial movement of said hub toward said second shoulder on said shaft, said radial projections on said hub having an axial length less than a distance between said first and second shoulders on said shaft whereby upon movement of said radial projections on said hub into engagement with said second shoulder said hub may be rotated relative to said shaft to move said radial projections on said hub into engagement with said radial projections on said shaft between said first and second shoulders on said shaft and a locking member having an annular flange slidably mounted on said shaft above said second shoulder and having at least one axially extending tooth disposed in sliding engagement with said shaft in at least one opening in said second shoulder for axial movement internally of the hub of said basket into one of said grooves in said shaft adjacent said radial projection on the hub to prevent reverse rotation of said hub thereby locking said basket on said shaft.
