Teleskopiskt fjädrande gåstav för träning

Patentradars sammanfattning

This invention by Sports Progress International AB relates to a telescopic spring-loaded training/walking pole (Nordic walking stick) comprising an outer tube, an inner tube, and a tube-sleeve bushing incorporating a distinctively shaped staple clamp (bygelformad krampa). The clamp features a neck portion with an external thread carrying a cap nut, plus an axially projecting leg pair terminating in radially directed flange-edge portions that serve as axial stops against the outer tube end and delimit band grooves receiving the doubled-over end portions of the elongated elastic element (band/rubber strap). A first slide guidance is achieved between the circular-segment-shaped free surfaces of the flange edges and the inner tube exterior, while a second slide guidance is provided by the elastic element end portions seated in the band grooves acting against the inner tube exterior, eliminating the need for a separate ring-shaped bushing guide and enabling a slimmer overall pole profile with easy elastic element exchange.
