Title
(DE) TREKKINGSTOCK MIT STOSSDÄMPFER
(EN) TREKKING STICK COMPRISING A SHOCK ABSORBER
(FR) BATON DE TREKKING DOTE D'UN AMORTISSEUR DE CHOCS
Abstract
(DE) Ein Stock (10) wie Trekking-, Ski-, Wanderstock, ist mit einem Stoßdämpfer (11) zwischen einem ersten und einem zweiten Rohrteil (13, 14) eines mit Handgriff und Stockspitze versehenen Stockrohres (12) versehen, wobei der Stoßdämpfer (11) eine in einem Rohrteil (13, 14) drehfest gehaltene Ftihrungshtilse (16), in der eine am anderen Rohrteil (14, 13) axial festgehaltene Dampferstange (26) geführt ist, und eine zwischen Führungshülse (16) und Dampferstange (26) wirkende Druckfedervorrichtung (30) aufweist. Damit bei einem derartigen Stock die stossdämpfenden Eigenschaften weniger hart und die Rückfederungseigenschaften weniger ruckartig und rückstossfreier sind, ist vorgesehen, dass die Druckfedervorrichtung (30) eine Elastomerfeder (29) aufweist, die in Reihenanordnung zu einer Druckwendelfeder (28) angeordnet ist.
(EN) A stick (10), such as a trekking stick, ski pole or walking stick, is provided with a shock absorber (11) between a first and a second tubular section (13, 14) of a stick shaft (12) that is equipped with a handle and a stick tip. According to the invention, the shock absorber (11) comprises a guide sleeve (16), which is held in a rotationally fixed manner in a tubular section (13, 14) and in which a damping rod (26) that is held in an axially fixed manner on the other tubular section (14, 13) is guided and a compression spring device (30), operating between the guide sleeve (16) and the damping rod (26). The aim of the invention is to obtain softer shock-absorbing characteristics and resilience characteristics that are less abrupt with minimal kickback. This is achieved by the provision of an elastomer spring (29) in the compression spring device (30), said spring being located in series with a helical compression spring (28).
(FR) Bâton (10), tel que bâton de trekking, bâton de ski, canne de promenade, muni d'un amortisseur de chocs (11) entre une première et une seconde section tubulaire (13, 14) d'un tube constituant le bâton (12) muni d'une poignée et d'une pointe. L'amortisseur de chocs (11) comprend un manchon de guidage (16) maintenu bloqué à l'encontre de toute rotation dans une section tubulaire (13, 14) et dans lequel est guidée une tige amortisseuse (26) qui est maintenue axialement fixe sur l'autre section tubulaire (14, 13), et un dispositif à ressort de compression (30) agissant entre le manchon de guidage (16) et la tige amortisseuse (26). En vue d'obtenir des propriétés d'amortissement plus atténuées et des propriétés d'élasticité moins saccadées et exemptes de rebond, l'invention est caractérisée en ce que le dispositif à ressort de compression (30) présente un ressort en élastomère (29) qui est disposé, en série, avec un ressort de compression hélicoïdal (28).
