ABSTRACT:
A touch panel for a swimming race comprises a rear panel, a front panel spaced from and opposed to the rear panel and movable vertically and horizontally relative to the rear panel, and a top edge panel having a first end portion connected to the rear panel and a second end portion connected to the front panel. A sensor is mounted in the space between the front panel and the rear panel and is actuable in response to rearward horizontal movement of the front panel for generating a signal. An elastic member is movably disposed in a space defined by the front panel, the rear panel and the top edge panel for biasing the top edge panel and the front panel vertically upwardly. A sliding member is disposed between the elastic member and the rear panel for reducing a friction between the elastic member and the rear panel during movement of the elastic member.
