| 摘要 |
The present invention consists of a bar with a mechanism at one end that serves a dual purpose: it allows the user to attach the bar in a non-permanent fashion to a ski pole shaft and it serves as a hinge so that the bar may be fixed in a position either parallel or transverse to the ski pole shaft. In the transverse position the device, when integrated with a ski pole, may be used by an experienced skier to either tow uphill or to control the speed of inexperienced skiers.
