産業上の利用分野
この発明は、人間の歩行運動、特に肢体不自由

ものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a gait analysis device for analyzing the walking motion of humans, especially the walking motion of physically disabled people during rehabilitation.
More specifically, the present invention relates to a support mechanism for a gait analysis device developed to improve the measurement accuracy of analysis results.
従来技術
歩行解析装置（いわゆるフオ−スプレ−ト）
は、人間の歩行状態を解析するための装置であ
り、その概要は３個または４個の荷重計を介して
支持された少なくとも一枚の平板を有し、この平
板上を歩行する人間の足底が受ける体重の変化を
荷重計により反力として計測し、この計測デ−タ
から歩行時における体重の揺動や足底に投影され
た重心の変化を定量的に解析しようとするもので
ある。Conventional technology Gait analysis device (so-called force plate)
is a device for analyzing human walking conditions, and its outline is that it has at least one flat plate supported through three or four load cells, and the human foot walking on this flat plate is used to analyze human walking conditions. The purpose is to measure the change in weight exerted on the sole of the foot as a reaction force using a load meter, and use this measurement data to quantitatively analyze the fluctuation of the body weight during walking and the change in the center of gravity projected onto the sole of the foot. .
ところで、歩行解析装置による解析結果の測定
精度は平板の材質や形状に大きく支配され、例え
ば低速で歩行する被測定者の歩行変化を高精度で
測定するには平板の振動モ−ドができるだけ高い
こと、つまり平板は可及的に剛体であることが必
要であり、また、歩行状態の十分な把握のために
は当然のことながら平板はある程度大きな歩行面
を有する必要がある。したがつて、満足すべき解
析結果を得るためには、歩行解析装置は形状的に
も重量的にも大きなもの（例えば歩行距離が２メ
−トル程度とれ、被測定者の体重の５〜６倍程度
の重量を有するもの）が要求される。 By the way, the measurement accuracy of the analysis results by the gait analysis device is largely controlled by the material and shape of the flat plate. For example, in order to accurately measure the gait changes of a subject walking at low speed, the vibration mode of the flat plate must be as high as possible. In other words, the flat plate needs to be as rigid as possible, and in order to fully understand the walking state, the flat plate needs to have a fairly large walking surface. Therefore, in order to obtain satisfactory analysis results, the gait analysis device must be large both in shape and weight (e.g., the walking distance is about 2 meters, and the measurement subject's weight is 5 to 6 meters). (about twice the weight) is required.
一方、解析結果の良否は測定感度に左右され、
被測定者が例えば子供のような場合には平板の反
力が小さくなるので、荷重計の感度を著しく上げ
る必要が生じ、さらにはＳ／Ｎ比は可能な限り良
好にすることが望ましい。 On the other hand, the quality of the analysis results depends on the measurement sensitivity.
If the person to be measured is a child, for example, the reaction force of the flat plate will be small, so it will be necessary to significantly increase the sensitivity of the load meter, and furthermore, it is desirable to make the S/N ratio as good as possible.
このため、従来の歩行解析装置はその設置場所
における各種外部振動を可能な限り排除すべく、
その多くは精密工作機械の据付工事に相当する十

歩行解析装置は、通常、建物の１階あるいは地下
階に設置するものとされ、高階への設置は考えら
れていなかつた。 For this reason, conventional gait analysis devices are designed to eliminate as much as possible various external vibrations at the installation location.
Most of them were installed in buildings with sufficient foundation work equivalent to the installation work of precision machine tools, or required reinforcement of the foundation work. Therefore,
Gait analysis devices are usually installed on the first floor or basement floor of a building, and installation on higher floors has not been considered.

蒙る肢体不自由者のリハビリテ−シヨンの便益に
十分供し得ない。Problems to be Solved by the Invention However, this limitation of installation locations not only increases installation costs;
This results in limited or missed opportunities for measurement, and as a result, it is not possible to provide sufficient benefits to the rehabilitation of physically disabled people, who would most benefit from this gait analysis device.

配置として現れるので図示を省略している。Embodiment As shown in FIGS. 1 and 2, the gait analysis device main body 1 includes a rectangular flat plate 2 and four load cells that detect reaction force components in the vertical direction (Z-axis direction) on the flat plate 2. 3, and two loads placed on each side of the flat plate 2 to detect the reaction force components of the flat plate 2 in the horizontal and vertical directions (X-Y direction) in FIG. 1, respectively. It is roughly composed of a total of 5 and 6 pieces. Here, the flat plate 2 preferably has a sandwich structure in which an aluminum honeycomb core material is sandwiched between carbon fiber-reinforced plastic plates, and each of the load cells 3, 5, and 6 has a strain gauge attached thereto. Preferably. In addition,
In FIG. 1, the upper half appears as a centrally symmetrical arrangement with the lower half, so illustration is omitted.

It is supported by 0. The flat plate 10 of the female support member 8 is mounted on a fixing plate 11, and the fixing plate 11 is fixed to a foundation stone 14 on a floor 13 via bolts 12.

The output from 6 is supplied to a subsequent data processing section via a preamplifier and a main amplifier. In addition, 17 is an air injection hole, and 18 is an air retention part.

When compressed air is supplied from 5, the male support member 7
An air layer is formed between the male support member 7 and the female support member 8, and the male support member 7 rises from the female support member 8.
That is, the gait analysis device main body 1 is in a state in which direct external vibrations from the floor 12 and the like are blocked.

動調芯が可能となる。 In the case of this embodiment, the male support member 7 and the female support member 8 have substantially trapezoidal side surfaces, so when focusing on one male support member 7, for example, in the X direction, Although free movement is ensured, the movement is restricted in the Y direction orthogonal to this. However, if we focus on the other male support member 7, on the contrary, it is restricted in the X direction, but free movement is ensured in the Y direction. In other words, the male support member 7 and the female support member 8 disposed below the flat plate 2 are arranged center-symmetrically, in other words, in a swastika shape, so when the flat plate 2 is installed, In this case, the movements in the X direction and the Y direction are mutually restrained, so even if the flat plate 2 floats, the position of the flat plate 2 will not shift significantly while the subject is walking. The center position of the flat plate 2 can always be kept at a predetermined position, making so-called automatic centering possible.

度良く確実に測定できるようになる。 In addition, by making the flat plate 2, floating plate 4, etc. have a multilayer structure, the load cells 5 and 6 that detect the reaction force component in the X-Y direction, the load cell 3 that detects the reaction force component in the Z-axis direction, and each layer This means that it can be placed separately for each
Interference between each reaction force component is avoided, and each reaction force component can be measured accurately and reliably.
また、上記実施例においては流体として空気を

どでも差し支えなく、また、雄型支持部材の形状
も、例えば半球状にすることも差し支えない。 Furthermore, although air is used as the fluid in the above embodiments, other fluids such as viscous oil may be used, and the shape of the male support member may also be, for example, hemispherical.

This eliminates the possibility of adverse effects, and has the effect of improving measurement sensitivity and measurement accuracy.
