LENGTH-ADJUSTABLE POLE AND CLAMPING DEVICE THEREFOR

摘要

The invention relates to a clamping apparatus (1) for a hiking pole, trekking pole, nordic walking pole, cross-country skiing pole or skiing pole for detachably axially fixing a pipe section (3) that can be inserted into an opening of the clamping apparatus, wherein the clamping apparatus comprises a plastic collar (5), which substantially directly encloses the pipe section (3) at least in an axial section and clamps the same in the closed state, wherein at least in the region (5b) enclosing the pipe section (2) the plastic collar (5) comprises at least one axial slot (6, 15) making the circumference of the plastic collar variable in said region and is designed in a substantially peripheral manner in the remaining axial region (5a), wherein on either side of said slot (6) a projection (13, 14) is arranged on the plastic collar (5), wherein said projections (13, 14) comprise a coaxial passage opening (23) which is arranged substantially perpendicular to the axis (24) of the pipe section (3) and through which a transverse pin (11) penetrates, which on the outside of the second projection (14) has a stop (12) and which on the outside of the first projection (13) has a rotational axis (7) for a clamping lever (4), the axis being arranged perpendicular to the axis of the transverse pin (11) and perpendicular to the axis (24) of the pipe section (3), wherein the clamping lever (4) comprises a lever arm (9), which at least partially encloses the plastic collar (5) when the clamping apparatus (1) is closed, and wherein the clamping lever (3) comprises a roll-off region (8), which is eccentric with respect to the rotational axis (7) and by means of which the distance between the stop (12) and a counter surface (19) arranged on the outside of the first projection (13) for clamping can be reduced by pivoting the clamping lever (4) into the closed position, and wherein the counter surface (19) is designed in the form of a metal element (16, 27) arranged at least partially in the first projection (13) in a depression (18).
