Document Type and Number:
Japanese Patent JP2018126373
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multiple jump detection system that can grasp the jumping number of times in the multiple jump, and provide a jumping rope and a jump board for use in the same.SOLUTION: A multiple jump detection system includes: a jumping rope having grips at both ends of a rope and having a magnet substantially in the center of the rope; a jump board for detecting the change of magnetic field generated by magnetic passage and the vibration being generated by jumping, calculating the jumping number of times and the rotational speed of the rope per 1 jumping based on detection results, and wirelessly transmitting the calculation results to the outside; and a display device for receiving the calculation results from the jump board and displaying the calculation results. The jump board comprises a body part and a leg part. The body part has a coil arranged substantially in the center of the body part; and a wireless module electrically connected with the coil, operated by having electric power supplied from the coil when the magnet passes the upper part of the coil by jumping, and wirelessly transmitting the calculation results to the outside. The leg part has an environmental power generation element electrically connected with the wireless module and generating electricity by the vibration to be generated by the jumping.SELECTED DRAWING: Figure 1
