摘要： A convertible sled can be dragged silently into the woods by the hunter. Once the hunter has bagged his game, he converts the sled into a track-driven and battery-powered cart. The sled portion is at the bottommost part of the assembly on the way into the woods. In this “sledding” mode, the battery pack, the tracks and the frame are situated above the sled. In the “carting” or “track-driving” mode, the sled is detached from the assembly and is remounted above the frame, tracks and battery pack. In this mode, the sled forms a platform upon which the game can be secured. In the carting mode, the hunter activates the track-driven cart to assist with extraction of the game. Activation of the track-driven cart is by means of a handle which extends to the front of the assembly. An alternative embodiment includes a pair of removable wheels mounted to a pair of adjustable wheel supports, which wheels may be used to roll the convertible sled as well.
摘要翻译：一只可转换的雪橇可以被猎人默默地拖入森林里。一旦猎人将他的游戏包装起来，他将雪橇转换成轨道驱动和电池供电的车。雪橇部分在进入树林的路上的组件的最底部。在这种“雪橇”模式中，电池组，轨道和框架位于雪橇上方。在“推车”或“跟踪驱动”模式下，滑板从组件拆下，并重新安装在框架，轨道和电池组上方。在这种模式下，雪橇形成游戏可以保护的平台。在推车模式中，猎人激活轨道驱动的推车以协助提取游戏。轨道驱动推车的激活是通过延伸到组件前部的把手。一个替代实施例包括一对可移动的轮子，其安装到一对可调轮支架上，这些轮子也可以用于滚动可转换滑车。

摘要： To improve convenience of a wheelchair by enabling an outside fitting type of auxiliary power device to be automatically and securely mounted on and removed from the habituated wheelchair, the auxiliary power device, which can be mounted on and removed from the wheelchair and provide power assistance to the wheelchair, comprises photoelectric sensors for detecting positions of predetermined frames of the wheelchair, arms, each having a handle of a shape capable of being engaged with the frames attached to an outer end thereof, and driving motors for displacing the arms. When the frames are determined to be at predetermined positions based on information from the photoelectric sensors, the arms are displaced by the driving motors so as to have the handles engage with the frames.
摘要翻译：为了通过使外部配合型辅助动力装置自动且牢固地安装在习惯轮椅上和从习惯轮椅上移除的辅助动力装置，可以安装在轮椅上并从轮椅上移除并提供动力辅助以提高轮椅的便利性轮椅包括用于检测轮椅的预定框架的位置的光电传感器，每个臂具有能够与附接到其外端的框架接合的形状的手柄，以及用于移动臂的驱动马达。当基于来自光电传感器的信息将帧确定在预定位置时，臂被驱动电机移位，以使把手与框架啮合。

摘要： A conversion kit with track and ski steering assemblies to convert a two-wheeled land vehicle such as a motorcycle or bicycle to a vehicle suitable for over-snow travel. A ski assembly mounts to the steering fork of the land vehicle in place of the front wheel. A track assembly mounts to the land vehicle in place of the rear wheel. A swing arm connects to and pivots upon the land vehicle frame and angles downward behind the frame. A track circulates a fixed path around a track carriage. The track carriage extends forward from a pivot connection with the rear of the swing arm, and pivots vertically under the swing arm in scissors-fashion. The land vehicle is suspended upon the track assembly using a single shock absorber and load-distributing bell crank. A snow compacting ramp attaches to the track carriage compresses the snow ahead of the track.
摘要翻译：具有轨道和滑雪转向组件的转换套件，用于将诸如摩托车或自行车的两轮陆地车辆转换成适合于超雪行驶的车辆。滑雪组件代替前轮安装在陆地车辆的转向叉上。轨道组件安装到陆上车辆以代替后轮。摆臂连接到陆上车架上并在车架后方向后倾斜。轨道围绕轨道车架循环固定路径。轨道滑架从与摇臂的后部的枢轴连接向前延伸，并且以剪刀方式在摆臂下方垂直地枢转。陆地车辆使用单个减震器和负载分配的曲柄曲柄悬挂在轨道组件上。轨道车架上的一个积雪坡道压紧轨道前方的雪。
