STARTING DEVICE FOR COMPETITOR IN SPORTS COMPETITION

摘要

PROBLEM TO BE SOLVED: To accurately measure response time of a competitor at the competition start.;SOLUTION: The starting device 1 includes at least one rear base 2 for fixedly holding the device on a competition surface, at least one detection sensor 3 connected to an electronic processing circuit, and one or two starting blocks 5, 5' for a competitor's foot. Each block is adjustably mounted on a longitudinal bar 10, which is connected to the base and activates the sensor or sensors to determine a response time at the competition start. The longitudinal bar is connected to an H-shaped structure 4, which includes two strips 14, 24, spaced apart. The ends of the two strips are rigidly connected to an immobile portion 7 of the rear base 2, while a central bar 6 connecting the two strips is secured to the rear end of the longitudinal bar. When a force is applied to the block(s), the central bar can be pushed in one direction via the bending of the two strips to activate the sensor, also to determine a response time at the competition start.;COPYRIGHT: (C)2013,JPO&INPIT
