Abstract

PROBLEM TO BE SOLVED: To provide a running machine simulating a curve of an actual road surface and an inclination from the center of a road surface to a road side face, for running training, in order to simulate running a straightaway as well as running a curve.SOLUTION: This running machine records position information corresponding to a running distance of an actual running path, and inclination angles of the road surface center and a road side surface of the position thereof, and adds a horizontal rotation angle of the running machine and the lateral inclination of the running machine according to the position information and the inclination angles of the position synchronized with the running distance of the running machine, to reproduce an actual running path.

Description

  The present invention enables running on a curve with a running machine.

  The running machine is called a treadmill or room runner and can run indoors, but it is a device that is fixed to the floor and is linearly moved because it runs on the belt around two rollers. I could only do it.

  When running on the road, the road contains a curve, and the center of the road and the side of the road are inclined.

  The actual road curve can be reproduced by recording the actual road curve data and horizontally rotating the running machine according to the distance traveled.

  When using an automobile traveling road in the running road for marathon running, the center of the road surface is high due to the problem of centrifugal force. An actual road surface cannot be realized with a horizontal running machine.

  The slope of the road surface center and road surface side can be reproduced by recording the slope data of the actual road and tilting the running machine to the left and right according to the current position.

  It is possible to reproduce the running on the inclined curve by horizontal rotation and right / left inclination.

  The problems to be solved are the data recording and the implementation method of the positional relationship between the travel distance and the curve, and the travel distance, the road surface center and the road surface inclination relationship.

  The distance between the mileage and the curve can be recorded from GPS or a map, and the distance between the mileage, the center of the road surface and the slope of the road surface can be recorded by recording data.

  To solve the positional relationship between the distance traveled and the curve, a mechanism that rotates horizontally around the position where the runner on the running machine rides is provided. By rotating the running machine by a necessary angle based on the angle data obtained from the fan-shaped angle between the current position b and the next position c from the center O of the curvature radius r, the same state as the actual road surface can be reproduced.

  The solution for the relationship between the distance traveled, the center of the road surface and the road surface side is provided with a mechanism that tilts the entire running machine to the left and right, placed on a horizontally rotating table, and the recorded distance between the travel distance and the road surface center and the road surface side. Based on this data, it can be reproduced by tilting the angle corresponding to the current position.

  The rotation speed of the angle is calculated by calculating the arrival time from the current speed of the runner and the distance from the current position to the next position, and by controlling to complete the rotation at the calculated time, smooth running is possible. Done.

The rotation amount and the left / right inclination angle can be synchronized with the data position of the running course. This is possible by having the data format as follows at regular distance intervals.
Latitude, longitude, left / right tilt angle

  If data of full marathon distance, 42.195 km is recorded at 1 m intervals, it becomes possible by recording the coordinate values and inclination angles of 42195 points. In addition to the hard disk, recording is possible by using a mass storage device such as a flash memory.

  By using a removable external storage device, the marathon course can be changed.

  In using the present invention, by displaying a landscape image corresponding to the distance traveled by the running machine or a map with a marker indicating the current position, the front state of the runway can be grasped, and a sense of reality can be obtained, and a straight run or a curve run can be obtained. Can be used safely.

  Curve running including road slope can be realized indoors with a running machine.
