Turning plate for measuring the pushing-off forces of swimmers

A turning plate for measuring push-off forces of swimmers during turning in a swimming pool defined in part by a pool wall that is disposed generally normal to a pool edge, comprising:

• a stiff plate;
• at least four force sensors for detecting the push-off forces applied by swimmers to the stiff plate;
• a stiff, rectangular frame on which the stiff plate is mounted on in at least four locations under pretension with a respective clamping screw and via a respective force sensor;
• wherein the frame has at least two stiff securing brackets for mounting on the edge of the pool;
• and
• wherein each securing bracket can be attached in two locations by a fixed component to the pool edge, each securing bracket having two slits wherein both of said slits are L-shaped and at least one of the two slits has a wide transversal slit at the inner end of the L for varying during mounting of the turning plate an inclination angle between the stiff plate and the pool edge.

A turning plate for measuring push-off forces of swimmers during turning at an end wall of a swimming pool, comprising:

• a stiff plate defining a center plane;
• a stiff rectangular frame that carries the turning plate, the stiff rectangular frame being configured for being stably attached to the end wall with the center plane of the stiff plate disposed at a predetermined orientation with respect to the end wall, the stiff rectangular frame being connected at four locations to the stiff plate, each of the four locations being spaced apart from one another;
• and
• a plurality of force sensors configured and disposed for detecting the push-off forces exerted against the stiff plate by the swimmers when turning, each one of the plurality of force sensors being spaced apart from each other;
• and
• wherein the stiff plate has a plurality of holes configured for a bow wave to pass therethrough.
