Definitions

  • the present invention relates to an apparatus comprising a strike pad and in particular to an apparatus where the power of an impact on the strike pad can be measured.
  • the device is for use in the field of martial arts or contact sports but also police, military, medical and recreational pursuits. It can also be used as a training tool in order to develop more power.
  • Practitioners have many kinds of martial arts and have a requirement to determine the force with which they can deliver a particular blow; be it with the hand, foot or other part of the body. Such a requirement can be as part of a training exercise to measure effectiveness or improvement in technique. Alternatively, this can be as part of a competition, where a comparison between different competitors needs to be made.
  • US2007/015637 discloses a training device for measuring the impact of an athlete on the training device. The board is struck which generates a voltage/current and from this information, the force required to generate such voltage or current is calculated.
  • Prior art devices generally measure the force of an impact. However, the force measured is, in part, dependent on the nature of the material being struck. It is also dependent on the area of contact at the point of impact. In addition, prior art devices have been so constructed that they have had difficulty in coping with combat sports in which a series of rapid blows is carried out as the recovery time for the particular measurement device is longer than the gap between adjacent blows.
  • the present invention seeks to address the above problems and provide an apparatus which can withstand higher powered and an increased number of impacts than is presently the case and can also carry out calculations even when a number of blows is quickly delivered.
  • the invention provides an apparatus which can be small, when so required, easily transportable and able to be set up at different locations and in different orientations, and critically, can be used with a partner negating the need for wall mount/load spreader or free standing metal frame.

  • the first resilient layer advantageously comprises a plurality of sub-layers: the different materials of the sub-layers assisting in appropriate energy distribution, which reduces the chance of damage to the user.
  • the second resilient layer is preferably formed from an open cell foam, which further preferably has a density of from 18-65kgm 3 .

  • the resilient first layer 1 1 may be formed of two separate layers (of approximate thickness 10mm and 35 mm respectively) to better absorb the impact, although for some applications, a single layer is sufficient.

This property ensures firstly that the strike pad is able to deal with even the most rapid exponent of a martial arts such as that of Taekwondo where a specialist can easily delivery four blows per second.
