    • An improved ski pole having an adjustable length is provided with two telescopically movable tube sections. The tube sections are inserted into each other and are movable relative to each other and are provided with a latch and a plurality of catches. When shortening the length of the ski pole, a spring is tensioned. The increasing of the length of the ski pole is caused by the tensioned spring. The switch is arranged at the reverse side of the grip of the ski pole. The latch is arranged fixedly at the inner tube section and the catches are arranged at a pivotable cylinder which can be elevated and lowered as well as rotated. The catches are defined by horizontally extending sections of at least one Z-shaped groove. The pivoting cylinder is connected at a off-center pivot point to the switching or operating, respectively, member. The entire mechanism for the longitudinal adjustment of the ski pole is arranged in the gripping section of the ski pole. This gripping section is easily mounted onto normal ski poles. The ski pole is specifically intended for cross-country skiers, who can adjust the ski pole to have three varying lengths depending upon the prevailing country shape whereby a chosen length is arrested by an interlocking of the tube sections which can be moved in each other. The pivoting cylinder may additionally comprise an axially extending additional coulisse. If the pivoting cylinder is rotated by the operating member such that the additional groove is aligned with the latch, the ski pole is in a condition in which it elastically yields in its longitudinal direction.
    • 具有可调节长度的改进的滑雪杆具有两个可伸缩运动的管段。 管段彼此插入并且可相对于彼此移动并且设置有闩锁和多个卡子。 当缩短滑雪杆的长度时,弹簧被张紧。 滑雪杆的长度的增加是由张紧的弹簧造成的。 开关布置在滑雪杆的手柄的相反侧。 闩锁被固定地布置在内管部分处,并且卡扣布置在可以升高和降低以及旋转的可枢转圆柱体处。 卡扣由至少一个Z形槽的水平延伸部分限定。 枢转气缸在偏心枢轴点处连接到分别切换或操作的构件。 用于滑雪杆纵向调整的整个机构设置在滑雪杆的抓握部分中。 这个抓握部分很容易安装在正常的滑雪杖上。 滑雪杆专门针对越野滑雪者,他们可以根据主要的国家形状调整滑雪杖,具有三种不同的长度,由此通过可相互移动的管段互锁来阻止所选择的长度。 枢转圆柱体可以另外包括轴向延伸的另外的凸缘。 如果枢转圆筒由操作构件旋转,使得附加凹槽与闩锁对准,则滑雪杖处于其纵向方向上弹性产生的状态。
