Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot shape measuring technique, and more particularly to a foot shape measuring apparatus suitable for measuring the size and shape of a foot.

(Prior Art) When selecting a shoe, it is preferable to know the foot length, foot width, foot circumference, etc. in order to select an appropriate size shoe. Therefore, conventionally, a method of measuring each dimension using a tape measure is used. The method of writing the contour of the foot on the paper was used. However, all of the above methods are liable to cause individual differences in measurement and lack accuracy.

Therefore, a foot-type measuring instrument is known as an example of a measuring instrument for measuring the above-mentioned dimensions (see Japanese Patent Publication No. 54-35810). This foot-type measuring instrument is equipped with a foot rest measuring cursor equipped with a foot rest cursor that is loosely fitted to the rail provided on the board, a foot length indicating rod with scales, and a foot width measuring cursor that is loosely fitted to the rail. The foot width measuring section is provided with a scaled support rod and the like, and the ankle height measuring section is provided with a scaled support pillar provided with an ankle height measuring cursor so as to be slidable up and down.

When measuring the foot length, the foot is placed on the substrate, the foot length indicating rod is slid, and the foot length reading unit reads the scale from the tip of the middle finger to the heel to measure the foot length. When measuring the foot width, slide the foot width measuring cursor to read the scale of the supporting rod and measure the foot width. Similarly, at the time of measuring the ankle height, the ankle height measurement cursor is slid to read the scale of the supporting column to measure the size of the ankle.

(Problems to be Solved by the Invention) However, the conventional foot-type measuring instrument has a complicated structure,
The measurement work is complicated and there is a problem in terms of measurement accuracy. That is, when measuring the size of the foot, the foot is placed on the board and the foot rest or foot strut is contacted, and then each cursor is slid to read the scale. The center of must be located at the center of the substrate. in this case,
Sometimes the subject is urged to move his or her feet a few millimeters, but it is difficult for the standing subject to follow the instructions while looking at his / her feet. There was a difficulty that both parties would be burdened. In particular, when measuring the length of the foot, when the center of the foot is from the longest toe to the heel, it is difficult to position the heel and a measurement error is likely to occur. Further, the foot length measuring section, the foot width measuring section and the ankle height measuring section have a structure that cannot be disassembled, and each has many constituent parts, which increases the weight of the entire body, and thus has a drawback that it cannot be easily carried.

The present invention has been made in view of the above problems, and an object thereof is to provide a foot-type measuring device that can measure each dimension of a foot accurately and easily, has a wide measurement range and is easy to carry. .

(Means for Solving the Problem) In order to achieve the above object, a foot-type measuring apparatus according to the present invention is a fixed plate, a footrest mounted at substantially the center of the fixing plate, and a footrest of the footrest. An opening larger than the outer shape is opened,

And a dimension measuring instrument having a positioning probe that is movably provided and is movable in the horizontal and vertical directions.

(Operation) With the above configuration, when measuring the foot length, the measurer previously marks the center of the second finger base on the toe side of the person to be measured and the heel point of the rear end of the heel, which is the last part of the foot. Keep it. Further, the probe of the dimension measuring instrument is horizontally moved so that its tip is aligned with the center line in the length direction of the movable plate. In this state, the feet are placed on the footrest to keep the body stable.

Next, the measurer freely slides the movable plate and moves the probe up and down to align the tip of the probe with the mark of the second finger root, and subsequently, to the mark of the heel point of the rear end of the movable plate. Align the centers. As a result, the center line of the movable plate in the lengthwise direction coincides with the center point of the foot, and the center line and the guide rail become parallel.

After that, two right-angled rulers and the like are used, one side of each right-angled ruler is along the guide rail, and the other side is brought into contact with the longest toe and heel point. Then, measure the distance between the right-angled rulers with a ruler. Then, this distance indicates the longest length of the foot, so that the measurer can know the length of the foot without the need for the person to be measured to move the foot on the footrest.
