Description

  The present invention relates to a stopwatch that is used to measure its own time during sprinting on land.

  Land sprints run from several seconds to several tens of seconds from the start to the goal. In the competition, the rank is determined by a difference of 1/100 seconds, and in practice, the time is measured with an accuracy of about 1/10 seconds. What can be done is required to evaluate running ability. While it is necessary to concentrate on running from the start to the goal in seconds to tens of seconds, the runner himself has both hands on the ground at the crouching start, and it is difficult to operate the stopwatch and the stopwatch switch operation at the goal In general, it is not possible to concentrate on driving, so time measurement is generally performed by a measurer other than the person himself / herself.

  When the person himself / herself measures the time in the practice of short-distance running on land, the stopwatch is pressed with a finger from the standing posture and the measurement is started at the same time as the measurement is started, and thereafter, (a) to (d) in FIG. In this way, a method is used in which the switch is pressed with the tip of the finger simultaneously with the goal while the position of the switch is confirmed by the touch of the tip of the finger in front of the goal point to end the measurement.

  Or, using a stopwatch with an automatic start function, sprinting from the crouching posture at the same time as the start sound, and confirming the position of the switch with the touch of the tip of the finger before the goal point, the switch at the tip of the finger simultaneously with the goal Is used to stop the measurement.

  In the case of short-distance running on land, it is necessary to concentrate the mind from the start preparation to the goal, and the time will be affected if the mind cannot be concentrated. In the above-mentioned method, in the time measurement of the person himself, using a stopwatch with an automatic start function, such as a problem that the running power is reduced due to starting from a standing posture different from the competition and accurate time measurement is not possible. Even if you start from a crouching posture, you can move your arm, use your fingertip sensations, or move your fingertips to check and operate switch positions that are completely unrelated to running before the goal. There was a problem that it was not possible to concentrate on the running, and the running ability was reduced and accurate time measurement was not possible.

  Therefore, the present invention can concentrate the spirit on running from the start position to the start dash, intermediate run, goal, and to measure the exact time in short distance practice. The purpose is to provide a stopwatch.

  In order to achieve the above object, the first invention is arranged to be pressed from the direction parallel to the direction of the finger to the palm side portion of the fingertip side end portion or the counter fingertip side end portion of the finger mounting cover. A finger wearing, characterized in that it has a switch, a calculation unit for processing and timing of the switch signal, a digital display unit, and a sound generation unit, and the stopwatch is activated by pressing the switch with a hand. This is a stopwatch device.

  The second invention is the stopwatch device according to the first invention, wherein when the switch is pressed, a warning sound and a preparation sound are generated, and then a start sound is generated, and at the same time, timing is started. Is a measurement method for displaying the time.

    The effect of the first invention is that when the person presses the switch of the stopwatch with the goal, the switch can be pressed only by holding the hand. It is a motion that can be performed naturally, and by moving the arm, using the sense of the tip of the finger, or moving the tip of the finger to confirm and operate the switch position that is completely unrelated to running as in the past It is possible to solve the problem that the spirit cannot be concentrated on the run, the running ability is reduced and the time cannot be measured accurately.

  The action according to the second invention is that when a switch is pressed, a warning sound, a preparation sound, a start sound are automatically generated, and further, measurement is automatically started simultaneously with the start sound, so it can be started in a crouching posture, By starting from a standing posture different from that at the time of the competition, the running ability will be reduced and the problem that accurate time cannot be measured will be solved.

  When measuring the short-distance time on land by yourself, a warning sound is generated by pressing the switch and the start position is prepared with the following preparation sound in the crouching posture while concentrating the spirit on the running by the sound Concentrate the nerve on the start sound while taking the attitude, and start dash at the same time as the start sound. Move to mid-running, and at the time of the last goal, just hold the hand in conjunction with the goal entry action that pushes out the head and chest, the switch is pressed to stop timing, and the time is displayed on the digital display .

  The person can concentrate on running from the starting position, and can score while keeping the same posture and movement as the competition, so the accurate time can be obtained without lowering the person's running ability. It can be measured.
