  • Patent number: 7802581
    Abstract: The invention describes a buffer (2) for a stick (1), in particular for a walking stick or a trekking or Nordic-Walking pole. The buffer (2) has means (10) for being attached to a stick tube (Ia), in particular in the form of a recess, at its upper end (4) and a rolling surface (5) at its lower end. In this case, the rolling surface (5) is of substantially flat or only slightly convex design in a transverse direction (22) in relation to the rolling motion but in a longitudinal direction (21) which is perpendicular thereto is convexly curved in such a way that it forms a rolling surface on a base surface (3) during the pushing-off movement with the stick when the user of the stick (1) moves.
