Description

  The present invention relates to an apparatus for measuring the position of a plantar arch formed on a human plantar, and more particularly to an apparatus for measuring the apex position of a lateral arch.

  A structure called a “plantar arch” is formed on the plantar of a human who walks upright on two legs in order to efficiently kick the ground and move forward. As shown in FIG. 4, the sole arch has a vertical arch (inside and outside) and a lateral arch, and three lines connecting the three points of the heel, the little finger, and the thumb form a three-dimensional arc. It is a curved surface to draw.

  The plantar arch connecting these three points acts as a spring to soften the impact during walking, and to distribute dynamic loads that take several times the weight of a person when trying to act . Furthermore, when the plantar arch is normally developed, it plays the role of a pump called a second heart that lifts blood (venous blood) by stretching and contracting the plantar arch each time it walks.

  Thus, the maintenance of a normal plantar arch is very important for human health. In order to maintain this plantar arch, conventionally, for example, as described in Patent Document 1, The use of a sole plate having a corresponding convex portion as a shoe sole or an insole of a shoe is performed.

The use of the plantar plate is an effective means for maintaining and forming a normal plantar arch, but it is necessary to accurately align the position of the convex portion formed on the plantar plate with the position of the plantar arch. It is important to match the apex of the convex part of the bottom plate with the apex of the lateral arch (the position corresponding to the bottom interosseous muscle of the sole). Conventionally, however, the positioning is based on the technical experience of engineers, craftsmen, etc., and the shape of the sole is measured with a footprint copier, etc., and the trial by the user is repeated many times. Because it was done by a trial and error method of adjusting based on a sense of incongruity, there was a problem that it was time consuming and troublesome.
Registered Utility Model No. 3055358

  The problem to be solved by the present invention is to provide a plantar arch position measuring device capable of accurately measuring the apex position of the lateral arch of the plantar arch in a short time.

  The plantar arch position measuring device of the present invention is a plantar arch position measuring device for measuring the apex position of a lateral arch in a human plantar arch, the plantar placing plate on which the plantar is placed, And a convex portion attached to the sole placement plate, the convex portion being attached so as to be adjustable in position in the front-rear and left-right directions.

  Moreover, it can be further provided with a correction plate to be brought into contact with the outer side portion of the human sole. In this case, the inclination angle of the correction plate with respect to the longitudinal direction of the sole placement plate is set to 16 degrees equal to the inclination angle of the outer portion of the sole having a normal lateral arch, and the correction plate is set to the longitudinal direction of the sole placement plate. It is attached so that it can move in the direction perpendicular to the direction.

  Further, a heel part inserting member that can be fixed by inserting a heel part of a human sole may be detachably fixed on the sole placement plate.

  Furthermore, the sole mounting plate may be made transparent, and a footprint sheet in which the shape of the sole of the person to be measured is copied may be stuck on the transparent sole mounting plate.

  According to the present invention, the convex portion having a shape corresponding to the apex of the lateral arch is attached on the sole placement plate so that the position can be adjusted in the front-rear and left-right directions. Therefore, the sole is placed on the sole placement plate. By adjusting the position of the convex portion several times, the vertex position of the lateral arch of the sole arch can be accurately determined and measured in a short time. And based on the measurement result of this vertex position, the sole plate which has the convex part corresponding to an exact horizontal arch can be produced easily, and the duplication can also be performed easily.

  In addition, in the case of having a correction plate having an inclination angle equal to the inclination angle (16 degrees) of the outer side of the sole having a normal lateral arch, the sole having a flat foot (open book leg) is broken by the lateral arch. Even in the case of the measurement object, the vertex position of the lateral arch in the normal state can be determined and measured by making the correction plate abut on the outer side of the sole for correction.

  Furthermore, with a heel part insertion member that can be fixed by inserting the heel part of a human sole, the position of the sole can be accurately determined during measurement, and the apex position of the lateral arch can be accurately determined. Can be measured.

  Furthermore, if the sole placement plate is made transparent and a footprint sheet that duplicates the sole shape of the person to be measured is pasted on the transparent sole placement plate, the back surface of the sole placement plate is used. The vertex position of the lateral arch can be determined while checking the sole shape of the person to be measured shown on the footprint sheet from the side, so the vertex position of the lateral arch is accurately determined and measured in a shorter time. be able to.

  Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 is a plan view showing an embodiment of a plantar arch position measuring apparatus according to the present invention. As shown in the figure, the plantar arch position measuring device includes a plantar placing plate 1, and the left and right soles are placed on the plantar placing plate 1 to determine the apex position of the lateral arch. And measure it.

  On the sole placement plate 1, a convex portion 2 having a shape corresponding to the apex of the lateral arch of the sole arch is attached. The convex portion 2 is provided so as to be slidable along the vertical slit 1a and the horizontal slit 1b provided on the sole placement plate 1, thereby enabling position adjustment in the front-rear and left-right directions. Further, the convex portion 2 can be fixed at the position after the front / rear / right / left position adjustment by a fixing means (not shown).

  Further, the correction plates 3 are attached to both sides of the sole placement plate 1. The correction plate 3 is attached so that the inclination angle with respect to the longitudinal direction of the sole placement plate 1 is 16 degrees (an angle equal to the inclination angle of the outer side of the sole having a normal lateral arch). The mechanism 4 is movable in a direction orthogonal to the longitudinal direction of the sole placement plate 1. By providing this straightening plate, even when the plantar whose arch is collapsed and becomes a flat foot (opened foot) is a measurement object, it is brought into contact with the outer side of the plantar to form a normal lateral arch. So that the sole can be corrected.

  Furthermore, a heel support plate 5 is erected on the sole placement plate 1 in order to define the position of the heel portion of the sole, and the heel support plate 5 has a heel when placing the sole. Just make contact.

  Also, in order to define the position of the heel portion of the sole, a heel portion insertion member 8 as shown in FIG. 2 can be attached to the proximal end portion of the sole placement plate 1. The heel insertion member 8 has a shape in which the tip of the shoe is opened, and is detachably fixed to the sole placement plate 1 with a hook-and-loop fastener or the like. Further, a fixing tape 8a for fixing the instep portion is attached to the buttock insertion member 8, and fixing and releasing are performed by a hook-and-loop fastener or the like.

  Returning to FIG. 1, a measuring element 7 is slidably attached to the scale portion 6 at the tip portion of the sole placement plate 1 in order to measure the size of the sole. The measuring element 7 has a length of about 2 cm along the longitudinal direction of the sole placement plate 1 and measures the size of the sole, and at the same time, determines the appropriate shoe size (the size of the sole + about 2 cm). You can also.

  Next, a method for measuring the apex position of the lateral arch by the plantar arch position measuring apparatus of the present embodiment will be described.

  First, the convex portion 2 is fixed at an appropriate position, and the sole of the subject is placed on the sole placement plate 1. Next, the correction plate 3 is moved and brought into contact with the outer side of the sole so that the lateral arch of the sole is in a normal state.

  In this state, the subject is stepped on the spot several times, and the position of the convex portion 2 is adjusted as appropriate based on the sense and discomfort, so that discomfort and pain do not occur. Assuming that the position of the convex part 2 corresponds to the apex position of the lateral arch, the position of the convex part 2 is measured and digitized with reference to, for example, the heel part of the sole. In order to facilitate the digitization, scales may be provided on the short side and the long side of the sole placement plate 1. Moreover, you may utilize the position measuring means using a laser beam or infrared rays.

  If the vertex position of the horizontal arch can be determined, the position of the vertical arch associated therewith can also be determined. Then, by digitizing these positions, the same shape can be easily duplicated when producing the second and third footplates.

  FIG. 3 is a plan view showing another embodiment of the plantar arch position measuring apparatus of the present invention. In the figure, the same components as those in the first embodiment shown in FIG.

  In the embodiment shown in FIG. 3, the footrest mounting plate 1 is formed of a transparent plate material, and a footprint sheet 9 obtained by copying the shape of the foot of the person to be measured is formed on the transparent footrest mounting plate 1. It is stuck. The footprint sheet 9 can be produced by an arbitrary method, for example, by applying ink to the measurement subject's sole and transferring it to paper. In addition, FIG. 3 has shown the state which stuck the footprint sheet 9 only on the right side.

  Next, a method for measuring the apex position of the lateral arch by the plantar arch position measuring apparatus of the present embodiment will be described.

  The convex portion 2 is fixed at an appropriate position, and the sole of the person to be measured is placed so as to coincide with the footprint sheet 9 on the sole placement plate 1. Next, the correction plate 3 is moved and brought into contact with the outer side of the sole so that the lateral arch of the sole is in a normal state.

  In this state, the measurer aligns the apex position of the convex portion 2 with the position considered to be the apex position of the lateral arch while viewing the footprint sheet 9 from the back side of the sole placement board 1. Then, the measurement subject is stepped on the spot several times, and the position of the convex portion 2 is finely adjusted based on the sense and the sense of incongruity so that the sense of incongruity and pain do not occur. Assuming that the position of the convex portion 2 corresponds to the vertex position of the lateral arch, the position of the convex portion 2 is measured and digitized in the same manner as in the first embodiment.

  Further, in the present embodiment, with the apex position of the convex portion 2 being matched, the sole of the measurement subject is photographed from the back side of the sole placement plate 1 with a digital camera or the like and recorded. The same shape can be easily duplicated when producing the foot plate of the third and third foot.
