1. A clamping apparatus for a hiking pole, trekking pole, Nordic walking pole, cross-country pole or ski pole for axially fixing an inside tube portion, which is insertable into an opening of the clamping apparatus, so as to be releasable,
wherein the clamping apparatus includes a plastic sleeve, which is fastenable on an outside tube portion which is insertable into a further opening of the clamping apparatus, encompasses the inside tube portion substantially directly at least in an axial portion and clamps it when the clamping apparatus is in the closed state, wherein, for the purposes of clampability, the plastic sleeveeither comprises at least one axial slot which makes the circumference of the plastic sleeve variable in said axial portion or is realized at least in regions from a deformable elastomer material,
wherein the clamping apparatus additionally comprises a clamping clip which is arranged coaxially with respect to the plastic sleeve, encompasses the plastic sleeve at least in part in the axial direction and clamps it when closed, wherein the clamping clip, at least in a region encompassing the plastic sleeve, comprises at least one axial slot, which makes the circumference of the clamping clip variable in said region, or elastic region, wherein on the clamping clip a first projection is arranged on a first side of said axial slot or rather elastic region and a second projection is arranged on a second side of said axial slot or rather elastic region, wherein each of said projections comprises a coaxial opening which is arranged in a substantially perpendicular manner to the axis of the inside tube portion, wherein a clamping lever is axially mounted on at least one of the projections, wherein the clamping lever comprises a lever arm which encompasses the clamping clip at least in part when the clamping apparatus is closed, and wherein the clamping lever comprises a roll-off region which is eccentric about a rotational axis of the clamping lever, by means of which roll-off region the spacing between a stop and a counter surface for clamping, which is arranged on the outside surface of the first projection, can be reduced as a result of pivoting the clamping lever into the closed position, and wherein the plastic sleeve is realized from two separate components, of which a first of the two separate components is realized as a tube sleeve, which is arranged coaxially with respect to the clamping clip, for fastening the clamping apparatus on the outside tube portion, and a second of the two separate components is realized as a clamping sleeve, which is arranged coaxially to the tube sleeve and to the clamping clip, for clamping the inside tube portion which is insertable into the outside tube portion. |
