FIG. 4 is a diagram showing a state in which a centrifugal toe force is measured by a toe force measuring device, and (a) is an enlarged side view of a main part showing a state of position adjusting means when a toe is fitted on a ring. FIG. 4B is an enlarged side view of the main part showing the state of the position adjusting means when the position of the ring is adjusted. FIG. 5C is a state when the toes are separated from the ring by pulling the ring by the position adjusting means. FIG.

<Checking the ring>
As shown in FIGS. 4A and 4B, it is checked whether the toe to be measured enters the ring 4 or not. If the size of the ring 4 does not match the size of the toe, the ring 4 is replaced with another ring 4 that matches the toe to be measured by the measurement subject.

At this time, if the toe is protruding from the recess 2c, the set screw N is loosened and the support plate 14 is moved in the front-rear direction so that the finger to be measured enters the recess 2c. adjust.

<Adjusting the direction of the toes>
Next, as shown in FIG. 3A, the toe to be measured is put in the ring 4, and the foot is placed so that the arm 12, the pulling wire 9 and the center of the ring 4 are in a straight line. The mounting plate 13 is rotated to align the ring 4. By doing so, as shown in FIG. 3A, the arm 12, the pulling wire 9 and the center of the ring 4 are aligned, and the pulling wire 9 comes into contact with the opening end of the notch portion 12c to cause friction. Resistance can be prevented from affecting the measured value. Therefore, the position of the toe fitted to the ring 4 can be adjusted by rotating the direction of the finger from the thumb to the little finger in an appropriate direction for measuring the pulling wire 9.

<Ring position adjustment>
Further, the connecting means 5 including the arm 12 and the pulling wire 9 is disposed between the lever 3c and the ring 4, so that the pulling wire 9 is freely bent and the position state of the ring 4 is reached. Can be changed freely. Thereby, the measurer who measures the toe force can freely move the ring 4 fitted to the toe, so that it is easy to measure the toe force.

Subsequently, as shown in FIG. 1, the measurer rotates the handle 22 in the direction of arrow A while watching the state of the person being measured, and rotates and adjusts the take-up bar 20, the gear 19 and the shaft 18 together. The wire 16 winds the connection member 8 so as to move in the forward direction of the arrow C (see FIG. 4B). Then, the connecting member 8 moves the measuring instrument main body 3a, the lever 3c, the arm 12, the pulling wire 9 and the ring 4 forward while the slider 8a is guided by the slide guides 2b and 2b and linearly moves forward. The position of the toe force measuring device 1 is adjusted by rotating the handle 22 to such an extent that the adjusting wire 16, the arm 12, the pulling wire 9 and the ring 4 do not swing (no play). Is completed (see FIG. 4B). This position-adjusted state prevents the adjusting wire 16 from moving backward in the direction of the arrow D by preventing the restraining means 21 from meshing with the tooth groove of the gear 19 and rotating backward. , Retained. This point is set as 0 point.
Then, the person to be measured signals to the measurer who winds the pulling wire 9 that the preparation for measurement is ready.

<Measurement of centrifugal toe force>
Next, the start switch 3f is turned on, and the measuring instrument 3 is brought into a state where the toe force can be measured.
As shown in FIG. 4B, in this state, the measurer instructs the subject to be pulled with the maximum gripping force. The person to be measured bends in the direction of grasping the toes and pulls the ring 4 backward. At this time, the toes of the foot are bent toward the upper surface 2a side of the pedestal 2, but since the recess 2c is formed under the toes and the ring 4, the fingertips and the ring 4 are in contact with the pedestal 2. Can be prevented. As a result, the toes and the ring 4 come into contact with the pedestal 2 and an extra burden is placed on the toes during measurement, thereby preventing hindrance measurement.
The measurer rotates the handle 22 in the arrow A direction at a constant speed to wind up the adjustment wire 16 and pulls the ring 4 in the forward direction of the arrow D.

As shown in FIG. 4 (c), the person to be measured will eventually be unable to withstand the force that the measurer rotates the handle 22 and pulls the ring 4, and a "Please stop" declaration, or The measurement is stopped when the toe is detached from the ring 4. At this time, the toe force endured by the toes is measured by the measuring mechanism 3d (see FIG. 2).
This toe force pulls the lever 3c rearward through the ring 4, the pulling wire 9, the connecting pin 11, and the arm 12, and is loaded on the load detection unit 3h (see FIG. 2).

The toe force is read by the load detector 3h shown in FIG. 2 and converted into an analog signal.
