Sensorized device for fastening climbing holds provided with a triaxial load cell

The invention relates to a device for fastening holds (10) for sport climbing equipped with a triaxial load cell (2) comprising two first pairs of strain gauges (A1, A2; A3, A4) and two second pairs of strain gauges (B1, B2; B3, B4) positioned respectively in a first plane (z1) and in a second plane (z2), in which the two planes (z1; Z2) are distinct from each other, are parallel to each other and are parallel to the plane costituted by a climbing wall (6) on which climbing holds are installed, each provided with the device for fastening holds (10); the device for fastening holds (10) further comprises a bushing (4) comprising two third pairs of strain gauges (A5, A6; B5, B6) positioned in a third plane (z3) parallel to the first plane (zl), the second plane (Z2) and the climbing wall (6); all the pairs of strain gauges have strain gauges arranged in parallel to the main axis of the hold fastening device (10); defined a cartesian reference system (x, y, z) for the device for fastening holds (10), in which the x and y axes are contained in the plane formed by the climbing wall (6) and are mutually perpendicular, with x parallel to the ground on which the climbing wall (6) rests, and in which the z axis is perpendicular to the plane of the climbing wall (6) and parallel to the plane of the climbing wall (6) and parallel to the main axis of the hold (10), the hold device (10) detects measurements of deformation in the x, y and z directions, from which the components of force fx Fy and Fz are derived in the corresponding directions x, y and z; the hold device (10) can also comprise an interface (12) and a computer (14) for the force data detected. The present invention finds preferred and advantageous applications in sport climbing training and competitions and also in functional recovery and psychomotricity.
