发明名称 APPARATUS FOR FORMING CROSS COUNTRY SKI TRACKS
摘要 <p>An apparatus for forming cross country ski tracks in a snow covered surface has a trailer frame adapted to be connected to the rear end of a vehicle. A lifting frame is connected to the trailer frame for pivotal movement about a first horizontal axis. The lifting frame has a pair of parallel guide members extending longitudinally from the trailer frame to a transversally extending crossbar. The guide members are arranged symmetrically on opposite sides of a central axis common to the lifting frame, the trailer frame, and the vehicle. At least one cross country ski track forming device is connected to the crossbar for pivotal movement about a second horizontal axis. A positioning device is connected between the trailer frame and the lifting frame. The positioning device pivotally manipulates the lifting frame about the first horizontal axis between an operative position at which the track forming device extends rearwardly from the trailer frame to contact and impress tracks in the snow covered surface, and an inoperative position at which the track forming device is elevated from the snow covered surface and is folded over the trailer frame.</p>
