Sports apparatus

Abstract

Sports apparatus, comprising a boxing body, a tensioning rope, a first, in particular upper, fastening, a second, in particular lower, fastening, the tensioning rope being clamped between the two fastenings, the tensioning rope interacting with the boxing body in such a manner that the boxing body is held in a basic position and that the boxing body can be displaced, in particular elastically, out of the basic position by the action of a boxing blow and is subsequently returned to the basic position, wherein the sports apparatus comprises a measuring arrangement which is set up to detect a boxing blow on the boxing body in a metrological manner.

1 . A sports apparatus ( 1 ), comprising a boxing body ( 2 ), a tensioning rope ( 3 ), a first, optionally upper, fastening ( 4 ), a second, optionally lower, fastening ( 5 ), wherein the tensioning rope ( 3 ) is clamped between the two fastenings ( 4 ,  5 ), wherein the tensioning cable ( 3 ) cooperates with the box body ( 2 ) in such a way that the box body ( 2 ) is held in a basic position and that the box body ( 2 ) can be displaced, optionally elastically, out of the basic position by the action of a boxing punch and is subsequently returned to the basic position again, wherein the sports apparatus ( 1 ) further comprises a measuring arrangement ( 21 ) which is set up to detect a boxing punch on the boxing body in a metrological manner. 
     
     
         2 . The sports apparatus ( 1 ) according to the  claim 1 , wherein the sports apparatus is set up to carry out an evaluation of the boxing punch on the basis of the metrological detection and to output an evaluation result to the user. 
     
     
         3 . The sports apparatus ( 1 ) according to the  claim 2 , wherein the boxing body can perform an oscillating movement, a boxing punch acting on the oscillating boxing body, in that the sports apparatus is set up to determine the time of the boxing punch in relation to the oscillating movement and to generate the evaluation as a function of the determined time. 
     
     
         4 . The sports apparatus ( 1 ) according to  claim 3 , wherein the sports apparatus is arranged to detect a rotational acceleration of the boxing body, and in that the sports apparatus is arranged to generate the evaluation as a function of the determined rotational acceleration. 
     
     
         5 . The sports apparatus ( 1 ) according to  claim 1 , wherein the sports device is set up to determine an at least two-dimensional trajectory (TR) of the boxing body, in particular to determine the trajectory in plan view, and that the sports apparatus is arranged to generate the evaluation as a function of the determined movement path (TR). 
     
     
         6 . The sports apparatus ( 1 ) according to  claim 5 , wherein the sports apparatus is arranged, during the generation of the evaluation trajectory (TR) of the boxing body during a first post oscillation (t4−>t6) and/or during a second post oscillation (t6−>t8) be considered. 
     
     
         7 . The sports apparatus ( 1 ) according to  claim 1 , characterized in that the sports apparatus comprises two separate acceleration sensors which are attached to the box body ( 2 ), namely a first acceleration sensor ( 211 ) for detecting a longitudinal acceleration (a), and a second acceleration sensor ( 212 ) for detecting a rotational acceleration (w), wherein the first acceleration sensor ( 211 ) is set up to detect a maximum longitudinal acceleration (a) of at least 100 g, in particular wherein the second acceleration sensor ( 212 ) being set up to detect a maximum rotational acceleration (a) of max. 20 g, in particular relative to a reference point on the surface of the box body to be detected. 
     
     
         8 . Use of the sports apparatus according to  claim 1 , comprising striking the sports apparatus of  claim 1 . 
     
     
         9 . The use according to  claim 8 , wherein, in order to set a preload after a boxing stroke, the period duration of the vibration of the box body generated by the boxing stroke is determined, in that the determined period duration is compared with a preset value, and that, based on the comparison result, the user is prompted to adjust the rope tension. 
     
     
         10 . The use according to  claim 9 , wherein the preset value is variable and is adjusted based on a user input.
