Device for instructing downswing in golf swing
First Claim
1. A start timing instructing device for informing a player of a body start timing for downswing in a golf swing, the device comprising:
- a sensor attachable to a wrist or a waist of the player and configured to detect changes in angle and acceleration associated with a backswing movement of the player;
a microprocessor configured to (i) set and adjust a predetermined start timing associated with a predetermined angle and acceleration data, (ii) identify a top position of the backswing movement based on the angle and acceleration data detected by the sensor, and (iii) generate a start timing instruction based on comparison between the predetermined angle and acceleration data and the detected angle and acceleration data; and
a stimulator attachable to the player and configured to generate a vibration, sound or electric stimulation upon receiving the start timing instruction from the microprocessor to inform the player of the body start timing for the downswing,wherein the predetermined start timing is adjustable with the microprocessor so as to instruct the player to start the body movement toward the downswing at a timing immediately before the detected backswing movement reaches at the identified top position, andwherein the microprocessor is configured to execute the following computer program list (A), (B) or (C);
(A) computer program list for a control using an angular velocity sensorAngular Velocity Sensor of lower limbs attached file

Abstract
A start timing instructing device includes a sensor attachable to the body of a player to detect changes in angle and/or acceleration associated with a backswing movement of the player. A variable resistor sets a start timing associated with a predetermined angle and/or acceleration data and has a volume by which the set start timing is adjustable. A microprocessor calculates an angle and/or acceleration data of the backswing movement based on the detected angle and/or acceleration and generates a start timing instruction if the calculated angle and/or acceleration data meet the angle and/or acceleration data which have been set and adjusted through the variable resistor and the volume. The microprocessor controls a stimulator attached to the body of the player to generate a vibration, sound or electric stimulation upon receiving the start timing instruction so as to inform the player of the body start timing for the downswing.
