Abstract

PURPOSE: To enable the detecting and displaying of the distribution of a physical weight and shifting condition thereof accurately with a simple structure by computing outputs of a plurality of pressure sensors arranged on a plane at each position thereof to display the magnitude of a pressure at each position. CONSTITUTION: A plurality of capacitance type pressure sensors 12 are arranged on the rear of a plate member as holding body through a rubber spacer. For example, when viewing changes (moving) in the physical weight working on both feet in golf swing, a subject is placed on the plate member and firstly, outputs (pressure data) of the sensors 12 are inputted into a computer 20 as changes in the frequency of an oscillation circuit 14 in an initial state to compute a pressure value. Then, the outputs of the sensors 12 are inputted at each about 0.3sec. to be stored while the pressure value is computed to be displayed on a monitor 26 by five stages of cycles indicating the difference of the pressure as changes in the distribution of the physical weight per about 0.3sec. from the initial state. This allows the determining of the shifting of the physical weight in time series with respect to the motion of a human body thereby accomplishing a variety of diagnosis and guidance easily and accurately.

According to the present invention, a plurality of pressure sensors such as a capacitive pressure sensor are arranged in a plane, and a holding member such as a plate member holding the plurality of pressure sensors on a plane is provided. A weight movement display device is provided with a computing means such as a computer for computing the output of each sensor for each position and a display means such as a CRT for displaying the magnitude of the computed pressure.

Further, according to the present invention, the pressure sensor has five positions for each foot according to the shape of a person's foot.
They are arranged in pairs, and the value of the pressure at each location is calculated by the calculation means and displayed by the display means. Further, the calculating means fetches the output value of each pressure sensor for every predetermined time and calculates the value, and displays the value of each pressure sensor for each time in whole or in part by the display means. .

[0007]

In the weight movement display device of the present invention, the weights at a plurality of places are detected by the pressure sensor, and the weight distribution is displayed as it is by the display means so that the weight distribution at that time can be surely visually recognized. It is a thing. Furthermore, by detecting and displaying the weight at each position in time series,
The movement and distribution of weight can be visually recognized.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention, and a weight movement display device 10 of this embodiment has an oscillation circuit 14 having a capacitive pressure sensor 12. The oscillator circuit 14 includes a pressure sensor 12, resistors 15 and 16, and amplifiers 17 and 18. And the pressure sensor 1
The output of 2 is input to the computer 20 which is a calculation means.

The oscillator circuits 14 are each provided with a capacitive pressure sensor 12, and two sets of five each are used. Each output is input to the computer 20. The arrangement of the five pressure sensors 12 in each set is as shown in FIG.
Five pieces are arranged around the circumference of the toe, one piece on the toe part, two pieces on both sides of the central portion, and two pieces on both sides of the heel.

Each pressure sensor 12 is arranged on the back side of the plate member 24, which is a holder, via a rubber spacer (not shown). One plate member 24 is provided for each foot shape 22, is supported by a rubber spacer, and is provided so as to be slightly tiltable as the center of gravity of a heavy object placed thereon moves.

The operation and action of the weight movement display device of this embodiment is such that, for example, when observing a change in how the weight of both feet is applied during a golf swing, the subject rides on the plate member 24 and moves on each foot 22. Swing with your left and right feet together. Then, at the time of this swing, the output value of each pressure sensor 12 is captured by the computer 20, calculated, and displayed.

In the calculation by the computer 20, for example, in the case of a golf swing, first, the output of each pressure sensor 12 in the initial state is fetched and the pressure value is calculated. The pressure data should be read as the frequency change of the oscillation circuit 14. Then, the output of each pressure sensor 12 is taken in every 0.3 seconds,
The pressure value is calculated while being stored. As shown in FIGS. 3 and 4, the calculation result is visually displayed on the monitor 26, which is a display means, as a six-step circle mark as a change in distribution of the weight every 0.3 seconds from the initial state.

In the case of this embodiment, what is shown in FIG. 3 is the result of weight shift measurement of a general subject, and what is shown in FIG. 4 is the result of weight shift measurement of a single player.
As described above, in the weight movement display device of this embodiment, the movement of the weight is moved, but it is clearly visible with the passage of time. Compare with the ideal state of weight movement in FIG. This makes it possible to see at a glance when and how to correct the weight.

The weight movement display device of the present invention is not limited to the above-mentioned embodiment, and can be used for health examinations and the like when examining a subject's sense of balance. Further, it can be used for inspection and practice of various sports. Further, the type and arrangement of the pressure sensor can be appropriately selected, and the detection means can detect not only the frequency but also the voltage value, and the calculation can be performed by a computer or a comparator. It is also possible to use and to perform a stepwise comparison display. Further, the holding member of the pressure sensor may be a plate member or a member divided for each pressure sensor, as long as each pressure sensor can detect the pressure at that position.
