摘要： A ski area trail map holder is provided for use with a ski pole. In one form, the holder comprises a tubular housing having a spring biased roller therein. The housing is attachable to the ski pole at any point along the pole. The ski area trail map is releasably secured to a map cover which is extendable from a retracted position in which it is rolled on the roller, to an extended position in which it is outside of the housing. The map cover comprises two transparent sheets, each of which is attached at one end to the roller and each of which has a free end located outside of the housing. A locking mechanism is provided for securing the map cover and/or map in an extended position. In a second embodiment, the ski pole itself acts as the outer housing for the map holder.

摘要： An amphibious vehicle is disclosed which is adapted for alternative land and water modes of operation and in which both modes of operation are performed efficiently. The amphibious vehicle includes a vehicle body supported, during land-bound operation, by a front pair of wheels and a rear pair of wheels. Each of the wheels of the vehicle are surrounded by specially-configured fender/sponson units which are rotatable between first and second operational positions through an angle of approximately 180.degree. about the encompassed wheel. In the first operational position, the fender/sponson units function as wheel tenders for land operation. In the second operational position, the fender/sponson units function as sponsons providing floatation to the vehicle and effectively contributing to the streamlined character of the vehicle during traverse through the water by presenting nautical wedges to the water. A rotation mechanism is provided for selectively rotating each of the fender/sponson units between their first and second operational positions. A drive train is provided to selectively propel the vehicle in the land and water modes of operation. The drive train includes a front wheel drive configuration for land-bound operation and a propeller for propelling the vehicle during water-borne operation. A transfer case directs the drive to either the front wheels or the propeller which can be selectively lowered, along with a rudder, for water-borne operation.

摘要翻译： 公开了一种适用于替代陆地和水运行模式的两栖车辆，并且其中有效地执行了两种操作模式。 水陆两用车辆包括在陆地操作期间由前一对车轮和后一对车轮支撑的车体。 车辆的每个车轮被特别配置的翼子板/支架单元围绕，该翼子板/支架单元可围绕围绕的轮在第一和第二操作位置之间旋转大约180度的角度。 在第一个操作位置，挡泥板/保护单元作为陆上作业的轮子投标。 在第二操作位置，挡泥板/保护单元用作向车辆提供漂浮的赞助商，并且通过向水中呈现航海楔形物来有效地促成车辆在穿过水中时的流线型。 提供旋转机构用于在其第一和第二操作位置之间选择性地旋转每个翼子板/支撑单元。 提供传动系以在陆地和水的操作模式中选择性地推进车辆。 传动系包括用于陆上操作的前轮驱动配置和用于在水上操作期间推进车辆的推进器。 分动箱将驱动装置引导到前轮或螺旋桨，其可以选择性地降下，并与方向舵一起用于水性操作。

摘要： An amphibious vehicle having retractable wheels and sliding hull sections. A novel suspension system is disclosed for raising and lowering the wheels on the vehicle. A coil spring/shock absorber is connected to a linkage which moves horizontally by action of a motor and worm gear coupled to the linkage. The lateral movement of the linkage results in vertical movement of the wheel. The amphibious vehicle may be driven directly into the water, and the wheels raised. Sliding hull sections are then positioned over the wheel wells to give the vehicle a streamline outer hull for water-borne travel.
