发明名称 Starting gate for BMX and mountain bike racing
摘要 A starting gate apparatus and method for use in bicycle races is provided. The starting gate includes a main platform, a plurality of gates connected to the main platform and a gate actuation arrangement to drive the gates from a bike stopping position to a bike releasing position. The gate actuation arrangement permits variations in at least one gate actuation parameter including an intermediate stopping position along a gate travel path, the driving force of the gate along the gate travel path, and/or an interval between initiation of an actuation sequence and actuation of the gate of the starting gate. Embodiments of the gate actuation arrangement permit a gate to independently act on an obstruction, provide for reversing, momentarily actuation of the gate during gate actuation or varying the duration or disposition of the interval of the gate actuation sequence.
