Construction for artificial ski run - has arms of V=shaped plastic moulded units fastened together to form track with sides as guides

摘要

The artificial ski run is constructed from separate units. Each is moulded from plastic and has two horizontal arms (1, 2) attached to a common vertical plate (6) at one end. This is notched (8) to enable the arms to spread in the form of a vee. Each arm has a curved cross section (4), the lower outer edge (3) resting on the ground. The upper surface has shallow bosses (5) and the other end of each arm has a side stop (9). Units are fastened together at these latter ends, each arm having a peg (14) entering a hole (13) in the adjoining unit to form a complete track.
