Abstract
Abstract The present invention relates to a safety handle for a ski pole and a safety knob for such handle, wherein said knob has a buffer body of elastic material, said body having at least one substantially elliptical cross-sectional area extending perpendicularly to the longitudinal axis of the ski pole. The safety knob is provided with means for attachment to the upper end of a conventional ski pole handle or the knob and the handle are constructed as an integral unit. In the latter instance the safety knob portion of the handle also comprises means for attaching the integral unit to the top of the ski pole.

Claim 1
Independent Claim
217 words
In a safety knob for the handle of a ski pole having a longitudinal ski pole axis which lies in a plane of symmetry for said knob, wherein a buffer body made of elastic material forms said knob, the improvement comprising an upwardly bulging first portion forming an ellipsoid having a minor axis and a major axis, said major axis extending in said plane of symmetry and perpendicularly to said ski pole axis, said major axis having a length corresponding substantially to the breadth of a human hand, a downwardly extending second portion facing toward said handle, said second portion merging into said first portion along the periphery of a first plane section defined by said minor and major axes, said second portion having a shape so that any one of a number of further plane sections extending in parallel to said first plane section is substantially an ellipse, said second portion tapering downwardly towards the ski pole in such a manner that said further plane sections diminish in area from said first plane section toward said ski pole, whereby said first and second portions together are shaped to provide in combination an elastical yielding of the knob in the direction of said ski pole axis and a large surface area on top of said first portion.
