Description

本発明は、例えば各種施設での実習や診察やリハビリテーション等の際に人体の関節回りにおける体幹と上肢または下肢等との角度の測定等に用いられる角度計に関する。   The present invention relates to an angle meter used for measuring an angle between a trunk and an upper limb, a lower limb, or the like around a joint of a human body, for example, in training, examination, rehabilitation, or the like at various facilities.

一般に、リハビリテーションや整形外科等の医療分野では、患者等の関節可動域を定量的に測定する機器として角度計(ゴニオメーター)が使用されている。例えば、身体機能の検査等に際し、体幹と上肢または下肢との角度や上腕と前腕との角度等の身体上の各部位の角度を測定することが行われている。これらの測定に用いられる角度計として、例えば支軸によってコンパス状に形成された第一アーム部と第二アーム部とを備え、一方のアーム部に固定された略円弧状の角度目盛り部によって他方のアーム部との間の角度を測定するようになっている。   In general, in the medical field such as rehabilitation and orthopedics, an goniometer is used as a device for quantitatively measuring a range of motion of a patient or the like. For example, when examining body functions, etc., the angle of each part on the body, such as the angle between the trunk and the upper or lower limbs, or the angle between the upper and lower arms, is measured. As an angle meter used for these measurements, for example, a first arm portion and a second arm portion formed in a compass shape by a support shaft are provided, and the other is provided by a substantially arc-shaped angle scale portion fixed to one arm portion. The angle between the arm portion and the arm portion is measured.

このような角度計では、測定精度を確保するために第一アーム部と第二アーム部の長さをある程度長く(例えば30cm程度)設定する必要がある。   In such an angle meter, it is necessary to set the lengths of the first arm part and the second arm part to be somewhat long (for example, about 30 cm) in order to ensure measurement accuracy.

また、他の角度計として、例えば特許文献1に記載された角度測定器が知られている。
この角度測定器は同一直線上にある第一固定アームと第二固定アームの中間に傾斜角度計が設けられ、この傾斜角度計の中心支軸に重力で垂下する回転バーが設けられている。そして、例えば上腕と前腕との角度を測定する際、上腕に沿って第一固定アームを設置し、関節を介して前腕に回転バーを位置させることで、両者間の角度を傾斜角度計で測定することができるとしている。
As another angle meter, for example, an angle measuring device described in Patent Document 1 is known.
This angle measuring device is provided with a tilt angle meter in the middle of the first fixed arm and the second fixed arm on the same straight line, and a rotating bar that is suspended by gravity is provided on the central support shaft of the tilt angle meter . And, for example, when measuring the angle between the upper arm and the forearm, install the first fixed arm along the upper arm and position the rotation bar on the forearm via the joint, and measure the angle between them with an inclinometer You can do that.

国際公開第2005/012829号International Publication No. 2005/012829

ところが、上述したアーム部の長い角度計はいずれも比較的高価であり、例えばリハビリテーションや整形外科等を専攻する医学生や技師見習いの学生等では個人で購入することが困難な場合がある。そのため、これらの学生等はアーム部の長さが上述した角度計より短い、例えば15cm程度の小型で低廉な角度計を個人で購入し、体幹と上肢または下肢との角度やその他の身体上の角度等を測定するのに用いていた。
しかしながら、角度計のアーム部の長さが短いと上肢や下肢に重ねた際にこれらの方向とずれ易く、正確な角度測定が困難であるという欠点があった。
However, all of the above-mentioned angle meters with long arm portions are relatively expensive, and for example, medical students majoring in rehabilitation, orthopedic surgery, etc., students who are apprentices of engineers, etc., may be difficult to purchase individually. For this reason, these students, etc., purchase a small and inexpensive angle meter with an arm portion shorter than the angle meter described above, for example, about 15 cm, and the angle between the trunk and upper or lower limbs or other physical It was used to measure the angle and the like.
However, if the arm portion of the angle meter is short, there is a drawback that it is difficult to accurately measure the angle because it is likely to deviate from these directions when superimposed on the upper or lower limbs.

本発明は、このような実情に鑑みて、アーム部の長さが短くても高精度な角度測定を行えるようにした角度計を提供することを目的とする。   In view of such circumstances, an object of the present invention is to provide an angle meter that can perform highly accurate angle measurement even when the length of an arm portion is short.

本発明による角度計は、第一アーム部と第二アーム部が支軸を中心に相対回転可能に支持され、第一アーム部または第二アーム部の自由端部に周方向に角度目盛りが付された角度表示部が回転可能に設けられ、該角度表示部には重力方向を示す指針が設けられ、角度表示部と指針を収容する表示ケースが設けられていて、該表示ケースは前記角度表示部と一体に回転可能とされ、指針は球体であることを特徴とする。
本発明による角度計によれば、通常は支軸を中心に第一アーム部と第二アーム部との角度を測定できると共に、支軸を挟んで第一アーム部と第二アーム部を直線状に延ばして一方のアーム部の端部に設けた角度表示部を例えば関節等の支点に配設し、第一アーム部と第二アーム部を角度測定の基準となる特定の身体部位、例えば体幹の方向に一致させて重力方向を示す指針に角度表示部の基準角度を位置合わせし、その後、角度表示部を支点として第一及び第二アーム部を例えば上肢または下肢等の他の身体部位の方向に回動させると、指針は重力方向で変わらないから、第一及び第二アーム部の示す方向の測定角度を角度表示部で測定することで、基準角度からの角度を例えば体幹と上肢または下肢との角度として測定できる。しかも、比較的短い長さの第一アーム部と第二アーム部を直線状につなげることで例えばほぼ倍の長さに設定できるから、例えば身体上の基準角度位置と測定角度位置とを高精度に設定して高精度の角度測定ができる。
In the angle meter according to the present invention, the first arm portion and the second arm portion are supported so as to be relatively rotatable about a support shaft, and an angular scale is provided in the circumferential direction on the free end portion of the first arm portion or the second arm portion. The angle display unit is rotatably provided, the angle display unit is provided with a pointer indicating the direction of gravity, and the angle display unit and a display case for accommodating the pointer are provided. It is possible to rotate integrally with the part, and the pointer is a sphere .
According to the angle meter of the present invention, the angle between the first arm portion and the second arm portion can be measured usually around the support shaft, and the first arm portion and the second arm portion are linearly arranged across the support shaft. The angle display part extended to the end of one arm part is arranged at a fulcrum such as a joint, for example, and the first arm part and the second arm part are used as a reference for angle measurement, for example, a specific body part such as a body The reference angle of the angle display unit is aligned with the pointer indicating the direction of gravity in accordance with the direction of the trunk, and then the first and second arm units are used as other fulcrum, such as the upper limb or the lower limb, with the angle display unit as a fulcrum. Since the pointer does not change in the direction of gravity, the angle from the reference angle is measured with the trunk, for example, by measuring the measurement angle in the direction indicated by the first and second arm portions with the angle display portion. It can be measured as the angle with the upper or lower limb. Moreover, by connecting the first and second arm parts with a relatively short length in a straight line, for example, the length can be set to almost double, so that the reference angle position and measurement angle position on the body can be set with high accuracy. High-accuracy angle measurement can be performed by setting to.

しかも、基準角度の設定に際し、重力方向の指針に対して表示ケースを回転させれば角度表示部も一体に回転するから、角度設定や角度調整が容易である。 In addition, when the reference angle is set, if the display case is rotated with respect to the hands in the direction of gravity, the angle display unit is also rotated together, so that angle setting and angle adjustment are easy.

しかも、指針は球体であり、球体は表示ケース内で常に重力方向に静止されるから、第一アーム部及び第二アーム部を他の身体部位の角度に応じて回動させることで、角度表示部が一体回転するため、球体との角度を容易に測定できる。 Moreover, since the pointer is a sphere, and the sphere is always stationary in the direction of gravity in the display case, the angle is displayed by rotating the first arm and the second arm according to the angle of the other body part. Since the part rotates integrally, the angle with the sphere can be easily measured.

また、支軸には第一アーム部と第二アーム部の相対角度を示す角度表示器が設けられている。
通常の使用状態では、支軸と同軸に設けた角度表示器に対して第一アーム部と第二アーム部のなす角度を測定できる。
The support shaft is provided with an angle indicator that indicates a relative angle between the first arm portion and the second arm portion.
In a normal use state, an angle formed by the first arm portion and the second arm portion can be measured with respect to an angle indicator provided coaxially with the support shaft.

本発明による角度計によれば、第一アーム部または第二アーム部の自由端部に角度目盛りが付された角度表示部が設けられているから、第一アーム部と第二アーム部の相対角度を測定できるだけでなく、第一アーム部と第二アーム部を同一直線状に配列させて測定すべき一方の方向を基準として他方の方向との角度を、角度表示部に設けた指針が示す角度によって測定できる。そのため、比較的長さの短い小型で低廉な角度計を用いて、第一アーム部及び第二アーム部を直線状に接続してより長い長さに設定することで、より精度の高い角度測定を行える。
しかも、基準角度の設定に際し、重力方向の指針に対して表示ケースを回転させれば角度表示部も一体に回転するから、角度設定や角度調整が容易である。また、指針は球体であり、球体は表示ケース内で常に重力方向に静止されるから、第一アーム部及び第二アーム部を他の身体部位の角度に応じて回動させることで、角度表示部が一体回転するため、球体との角度を容易に測定できる。
According to the angle meter of the present invention, since the angle display unit with an angle scale is provided at the free end portion of the first arm unit or the second arm unit, the relative relationship between the first arm unit and the second arm unit is provided. Not only can the angle be measured, but the pointer provided on the angle display unit indicates the angle between the first arm and the second arm that are to be measured with the same straight line as the reference and the other direction. Can be measured by angle. Therefore, using a small and inexpensive angle meter with a relatively short length, the first arm and the second arm are connected in a straight line and set to a longer length, allowing more accurate angle measurement. Can be done.
In addition, when the reference angle is set, if the display case is rotated with respect to the hands in the direction of gravity, the angle display unit is also rotated together, so that angle setting and angle adjustment are easy. In addition, since the pointer is a sphere, and the sphere is always stationary in the direction of gravity in the display case, the angle is displayed by rotating the first arm and the second arm according to the angle of the other body part. Since the part rotates integrally, the angle with the sphere can be easily measured.

以下、本発明の実施の形態について、図面に基づいて説明する。
図1は本発明の実施形態による角度計1を示すものであり、例えば15cm程度のほぼ等しい長さの第一アーム部2と第二アーム部3とがそれぞれ一端部で支軸4を中心に相対回転可能に連結されている。支軸4には支軸4を中心にして第一アーム部2と第二アーム部3の幅と同一長さを外径寸法とした全円形の角度表示器5が設けられている。第一アーム部2と第二アーム部3は角度表示器5を挟んで同一直線状に延ばすことで各アーム部2,3の略2倍の長さにすることができる。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an angle meter 1 according to an embodiment of the present invention. For example, a first arm portion 2 and a second arm portion 3 of approximately the same length of about 15 cm are respectively centered around a support shaft 4 at one end. They are connected so that they can rotate relative to each other. The support shaft 4 is provided with an all-round angle indicator 5 whose outer diameter is the same length as the width of the first arm portion 2 and the second arm portion 3 around the support shaft 4. The first arm portion 2 and the second arm portion 3 can be made approximately twice as long as the arm portions 2 and 3 by extending in the same straight line with the angle indicator 5 interposed therebetween.

第一アーム部2と第二アーム部3はそれぞれ支軸4の中心を通過する中心線2a、3aが設けられている。角度表示器5は例えば第一アーム部2に固定されており、中心線2aに0度の位置が重なっている。そして、角度表示器5は例えば0度を中心に左右両側方向に180度ずつ角度表示されている。そのため、第一アーム部2の中心線2aに対する第二アーム部3の中心線3aのなす角度を角度表示器5で読み取ることで角度測定ができる。また、第一アーム部2には、例えばその長手方向の両端縁に長さの寸法表示がなされている。   The first arm portion 2 and the second arm portion 3 are provided with center lines 2a and 3a passing through the center of the support shaft 4, respectively. The angle indicator 5 is fixed to the first arm portion 2, for example, and the position of 0 degree overlaps the center line 2a. For example, the angle display 5 displays an angle of 180 degrees in both the left and right directions around 0 degrees. Therefore, the angle can be measured by reading the angle formed by the center line 3a of the second arm part 3 with respect to the center line 2a of the first arm part 2 with the angle indicator 5. In addition, the first arm portion 2 is displayed with a length dimension at, for example, both end edges in the longitudinal direction.

図2及び図3において、第二アーム部3の自由端部、即ち角度表示器5と反対側の端部に天板付きで略円筒状の表示ケース7が第二アーム部3に対して回転可能に支持されている。第二アーム部3に対する表示ケース7の回転構造は図では省略されているが、例えば円形の凸部と凹部とを摺動可能に嵌合させた構造等を採用してもよい。
表示ケース7内には全円形の角度表示部8が設けられており、角度表示部8は表示ケース7と一体且つ同軸に回転可能とされている。角度表示部8は例えば0度を中心に左右方向に180度まで例えば5度刻みで目盛りが表示されている。第二アーム部3の中心線3aは角度表示部8の回転中心と一致するものであり、表示ケース7を回転させることで、角度表示部8の0度を中心線3aに一致させることができる。
そして、表示ケース7内には指針をなす球体9が挿入されており、球体9は表示ケース7内を自由に移動可能であり、その停止位置は重力方向の角度目盛りを指示することになる。これら表示ケース7,角度表示部8,球体9は角度器10を構成する。
角度計1は例えばプラスチック製であり、球体9は例えばプラスチック製または金属製である。
2 and 3, a substantially cylindrical display case 7 with a top plate at the free end of the second arm 3, that is, the end opposite to the angle indicator 5, rotates with respect to the second arm 3. Supported as possible. Although the rotation structure of the display case 7 with respect to the second arm portion 3 is omitted in the drawing, for example, a structure in which a circular convex portion and a concave portion are slidably fitted may be employed.
In the display case 7, an all-round angle display unit 8 is provided, and the angle display unit 8 is rotatable integrally with the display case 7 and coaxially. The angle display unit 8 displays scales in increments of 5 degrees, for example, up to 180 degrees in the left-right direction centered on 0 degrees. The center line 3a of the second arm part 3 coincides with the rotation center of the angle display part 8, and by rotating the display case 7, 0 degree of the angle display part 8 can coincide with the center line 3a. .
A sphere 9 serving as a pointer is inserted into the display case 7, and the sphere 9 can freely move in the display case 7. The stop position indicates an angular scale in the direction of gravity. These display case 7, angle display unit 8, and sphere 9 constitute an angle device 10.
The goniometer 1 is made of plastic, for example, and the sphere 9 is made of plastic or metal, for example.

本実施形態による角度計1は上述の構成を備えており、次にその使用方法について説明する。なお、図において、角度計1を用いた測定者は省略する。
まず、鉛直方向において、起立状態の被検査者の体幹に対する腕の持ち上げ角度(大関節)を測定する。そのために、先ず図3及び図4(a)に示すように、被検査者の体幹の方向に沿って角度計1を位置させて下方に延ばす。その際、角度計1の角度器10を上端にして肩峰または肩関節に位置させ、第二アーム部3と第一アーム部2を鉛直方向に直線状に垂下させる。この状態で、球体9はその重力により表示ケース7内で鉛直方向の下端に位置するものであり、角度器10の表示ケース7を回転させて角度表示部8の0度の位置を球体9に一致するように微調整する。角度表示部8のこの位置を角度測定の基準位置とする。
The angle meter 1 according to the present embodiment has the above-described configuration, and the usage method will be described next. In the figure, the measurer using the angle meter 1 is omitted.
First, in the vertical direction, the arm lifting angle (large joint) with respect to the trunk of the subject who is standing is measured. For this purpose, first, as shown in FIGS. 3 and 4A, the goniometer 1 is positioned along the direction of the trunk of the examinee and extended downward. At that time, the angle device 10 of the goniometer 1 is placed at the shoulder peak or shoulder joint with the angle device 10 as the upper end, and the second arm portion 3 and the first arm portion 2 are suspended in a straight line in the vertical direction. In this state, the sphere 9 is positioned at the lower end in the vertical direction in the display case 7 due to its gravity, and the display case 7 of the angle device 10 is rotated so that the 0 degree position of the angle display unit 8 is set to the sphere 9. Fine tune to match. This position of the angle display unit 8 is set as a reference position for angle measurement.

そして、図4(b)に示すように、腕を外転させて上方に持ち上げる。角度器10を中心にして、角度計1全体を反時計回りに回転させて持ち上げた腕に略平行に重ねると、角度表示器8も一体に回転する。この状態で、図4(c)に示すように、球体9は表示ケース7の最下端である重力方向に位置し、その球体9の位置における回転した角度表示部8の目盛り(例えば100度)を読むと、体幹に対する腕の持ち上げ角度を測定できる。   Then, as shown in FIG. 4 (b), the arm is abducted and lifted upward. When the entire angle meter 1 is rotated counterclockwise around the angle device 10 and overlapped with the lifted arm substantially in parallel, the angle indicator 8 also rotates integrally. In this state, as shown in FIG. 4C, the sphere 9 is positioned in the direction of gravity, which is the lowermost end of the display case 7, and the scale (for example, 100 degrees) of the rotated angle display unit 8 at the position of the sphere 9 is provided. Can be used to measure the arm lift angle relative to the trunk.

次に図6に示すように、患者等がベッドに寝た状態から膝を折り曲げて大腿部を上方に回動させた状態における体幹と大腿部との角度(大関節)を測定する。
まず、図5及び図6(a)に示すように、角度計1を水平方向に延びる身体に合わせて直線状をなす第二アーム部3及び第一アーム部2を水平に保持させ、下肢を回動させる支点をなす腰関節の部分に角度器10を位置させる。このとき、図5に示すように、角度器10において球体9はその重力により表示ケース7内の下端に垂下した状態にあるから、球体9の位置に角度表示部8の0度の目盛りが重なるように表示ケース7を回転させて調整する。この位置を基準位置とする。
Next, as shown in FIG. 6, the angle (large joint) between the trunk and the thigh in a state where the patient is lying on the bed and the knee is bent and the thigh is rotated upward is measured. .
First, as shown in FIG. 5 and FIG. 6 (a), the second arm part 3 and the first arm part 2 that form a straight line according to the body extending in the horizontal direction are held horizontally, and the lower limbs are The angle device 10 is positioned at the portion of the hip joint that forms the fulcrum to be rotated. At this time, as shown in FIG. 5, in the angle device 10, the sphere 9 is suspended from the lower end in the display case 7 due to its gravity, and therefore the 0-degree scale of the angle display unit 8 overlaps the position of the sphere 9. Thus, the display case 7 is rotated and adjusted. This position is set as a reference position.

この状態から、図6(b)に示すように、膝を折り曲げて大腿部を上方に回動させて保持する。そして、角度計1について角度器10を中心にして反時計回りに回動させて第二アーム部3及び第一アーム部2が一直線状のまま大腿部に略平行に重なるように保持する。
この状態で、表示ケース7内で重力方向の位置にある球体9に対して、角度器10を回動の支点として第二アーム部3及び第一アーム部2を直線状に保持して大腿部の角度まで回動させるため、図6(c)に示すように、角度器10も大腿部の持ち上げ角度まで回動した位置にある。この状態で、図6(c)に示すように、球体9は表示ケース7の最下端である重力方向に位置し、その球体9の位置における回転した角度表示部8の目盛り(例えば105度)を読むと、体幹に対する大腿部の持ち上げ角度を測定できる。
そのため、角度計1によって大腿部が例えば105度の角度まで回動したことを測定できる。
From this state, as shown in FIG. 6 (b), the knee is bent and the thigh is rotated upward and held. Then, the angle meter 1 is rotated counterclockwise around the angle device 10 so that the second arm portion 3 and the first arm portion 2 are kept in a straight line so as to be substantially parallel to the thigh.
In this state, the second arm portion 3 and the first arm portion 2 are held linearly with the angle device 10 as a fulcrum of rotation with respect to the sphere 9 located in the gravity direction in the display case 7. In order to rotate to the angle of the part, as shown in FIG. 6C, the angle device 10 is also in the position rotated to the thigh lifting angle. In this state, as shown in FIG. 6C, the sphere 9 is positioned in the gravity direction, which is the lowermost end of the display case 7, and the scale (for example, 105 degrees) of the rotated angle display unit 8 at the position of the sphere 9. Can be used to measure the thigh lift angle relative to the trunk.
Therefore, it can be measured by the goniometer 1 that the thigh has been rotated to an angle of, for example, 105 degrees.

なお、手首の角度や指の角度等、小関節における腕や指等の角度を測定する場合には、角度表示器5を小関節に重ねて配設し、第一アーム部2と第二アーム部3をそれぞれの指や前腕部等に重ねることで、従来の小型の角度計と同様に角度表示器5によって角度測定が行える。   When measuring the angle of the arm or finger at the small joint, such as the wrist angle or the finger angle, the angle indicator 5 is placed over the small joint, and the first arm unit 2 and the second arm By overlapping the part 3 on each finger, the forearm part, etc., the angle can be measured by the angle indicator 5 as in the conventional small angle meter.

上述のように本実施形態による角度計1は、垂直面内において、垂直方向の体幹に対する腕部の回動角度や、水平方向の体幹に対する大腿部の上方への回動角度を、第一アーム部2及び第二アーム部3を直線状に延ばした状態で、第一及び第二アーム部2,3の約2倍の長さのアーム部として角度の測定ができる。そのため、第一アーム部2と第二アーム部3の長さが比較的短い小型の角度計1を用いても、第一アーム部2及び第二アーム部3の約2倍の長さのアーム部を基準として体幹に対する腕部や大腿部の曲がり角度等の測定を行うことができて、より高精度な角度測定が行える。
また、通常の測定に用いられる、第一アーム部2に対する第二アーム部3の角度についても支軸4を中心とした角度表示器5によって測定できる。
As described above, the angle meter 1 according to the present embodiment, in the vertical plane, the rotation angle of the arm part with respect to the trunk in the vertical direction and the rotation angle of the upper part of the thigh with respect to the trunk in the horizontal direction, In the state where the first arm portion 2 and the second arm portion 3 are linearly extended, the angle can be measured as an arm portion having a length approximately twice that of the first and second arm portions 2 and 3. Therefore, even if the small angle meter 1 in which the lengths of the first arm part 2 and the second arm part 3 are relatively short is used, the arm is approximately twice as long as the first arm part 2 and the second arm part 3. The angle of the arm and thigh with respect to the trunk can be measured with reference to the body, and more accurate angle measurement can be performed.
Further, the angle of the second arm portion 3 with respect to the first arm portion 2 used for normal measurement can also be measured by the angle indicator 5 with the support shaft 4 as the center.

以上、本発明の実施の形態による角度計1について説明したが、本発明は上記した実施の形態に限定されるものではなく、その趣旨を逸脱しない範囲内で適宜変更可能である。
例えば、角度器10において、指針として球体9に代えて表示ケース7及び角度表示部8の回転中心に軸部を設けて、この軸部から重力方向に垂下させた指示針を設けてもよい。特に指示針の重量を比較的大きくすれば、より精度よく重力方向に垂下させて指示することになる。
この場合には、表示ケース7は必ずしも設けなくてもよい。
また、上述の実施形態では、角度器10を第二アーム部3の自由端部に設けたが、これに代えて第一アーム部2の自由端部に設けてもよいことはいうまでもない。また、第一アーム部2及び第二アーム部3の自由端部にそれぞれ角度器10を設けてもよい。
なお、指針としての球体9や指示針は透明体に形成してもよく、この場合には角度指示部8の目盛りをより精度良く目視確認できる。
The angle meter 1 according to the embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.
For example, in the angle device 10, instead of the sphere 9 as a pointer, a shaft portion may be provided at the rotation center of the display case 7 and the angle display portion 8, and an indicator needle suspended from the shaft portion in the gravity direction may be provided. In particular, if the weight of the indicator needle is made relatively large, the instruction is made by hanging down in the direction of gravity more accurately.
In this case, the display case 7 is not necessarily provided.
Moreover, in the above-mentioned embodiment, although the angle device 10 was provided in the free end part of the 2nd arm part 3, it cannot be overemphasized that it may replace with this and may be provided in the free end part of the 1st arm part 2. . Moreover, you may provide the angle device 10 in the free end part of the 1st arm part 2 and the 2nd arm part 3, respectively.
Note that the sphere 9 or the indicator needle as a pointer may be formed on a transparent body, and in this case, the scale of the angle indicator 8 can be visually confirmed with higher accuracy.

また、本実施形態では、角度計10について身体における体幹や上肢、下肢等との間の関節回りにおける相互の回転角度を測定するものとしたが、本発明は、このようなリハビリテーション用や医療検査用等における身体の角度測定用の角度計に限定されるものではなく、鉛直方向または重力方向における他の適宜の相互の部材間の角度測定にも用いることができる。
なお、上述した本発明による角度計1は角度器10が鉛直面内または鉛直方向を含む傾斜面内に保持され、指針が重力方向を指示する状態で各種の部材間等の角度の測定に用いることができる。角度器10を完全な水平面内に保持した場合には指針が重力方向を指示しないので、角度測定にはそぐわないことがある。
Further, in the present embodiment, the angle meter 10 is used to measure the mutual rotation angle around the joint between the trunk, the upper limb, the lower limb, etc. of the body, but the present invention is applicable to such rehabilitation and medical treatment. It is not limited to an angle meter for measuring the body angle in inspection or the like, but can also be used for angle measurement between other appropriate members in the vertical direction or the gravity direction.
The angle meter 1 according to the present invention described above is used to measure angles between various members in a state where the angle device 10 is held in a vertical plane or an inclined plane including a vertical direction, and the pointer indicates the direction of gravity. be able to. When the angle device 10 is held in a complete horizontal plane, the pointer does not indicate the direction of gravity, so that it may not be suitable for angle measurement.

本発明による角度計は、支軸で支持する第一アーム部と第二アーム部の挟角を測定すると共に、両アーム部を一直線状に延ばして第一アーム部または第二アーム部の自由端部に角度目盛りが付された角度表示部を回転可能に設けて、小型且つ低廉であっても、重力方向を示す指針との関係で精度の良い角度測定ができるようにしたものである。この角度計はリハビリテーション用や医療検査用等における身体の角度測定用だけなく、任意の分野における鉛直方向または重力方向における適宜の相互の部材間の角度測定にも用いることができる。   The angle meter according to the present invention measures the included angle between the first arm part and the second arm part supported by the support shaft, and extends both arm parts in a straight line so that the free end of the first arm part or the second arm part An angle display unit with an angle scale attached to the unit is rotatably provided so that even if it is small and inexpensive, it can measure the angle with high accuracy in relation to the pointer indicating the direction of gravity. This angle meter can be used not only for measuring the angle of the body for rehabilitation and medical examination, but also for measuring the angle between appropriate members in the vertical direction or gravity direction in any field.
