、１８ｂ、１８’ｂを中心に回転する。こうすると梃子
１６ａの三角溝２６ａ。26'a is fitted with the knife fittings 32, 32' of the rods 30, 30' which protrude from the sides of the cup-shaped suppressor 28. The flat pieces 26b and 26'b provided on the lower surface of the center side end of the lever 16b are knife fittings 32 of the rods 30 and 30'.
．． 32'. The lower surface of the center of the suppressor 28 presses a load measuring element 38 fixed to the base 12 via three balls 34 and a receiver 36 arranged in a triangular shape by a shallow recess. The load measuring element 38 is connected to a display device (not shown).゛This vehicle scale operates as follows. When the wheels are placed on the base plate 10, the flat pieces 24a, 24'a, 24b
, 24'b is the knife lever 22a of levers 16a and 16b.
, 22'a, 22b, 22'b, the levers 16a, 16b are the knife levers 18a, 18'a.
, 18b, 18'b. In this way, the triangular groove 26a of the lever 16a.
２６′ａおよび梃子１６ｂの平面片２６ｂ、２６’ｂは
ナイフェツジ３２ 、３２’を押し下げるので、押圧体
２８は球３４を介して荷重測定素子３８を押し下げる。26'a and the flat pieces 26b, 26'b of the lever 16b press down on the knives 32, 32', so that the pressing body 28 presses down the load measuring element 38 via the ball 34.
荷重測定素子３８は荷重を電気信号に変換し、その出力
信号により表示装置は重量測定値を表示する。The load measuring element 38 converts the load into an electrical signal, and the output signal causes the display device to display the weight measurement value.
このときこのはかりでは梃子１６ａ、１６ｂの回転運動
によって生ずるナイフェツジ３２゜３２′すなわち抑圧
体２８の水平方向の変位は、球３４の転勤によって吸収
されるので、荷重測定素子３８に水平方向の力は加わら
ない。しかも球３４は三角形状に配置されているので、
抑圧体２８は傾くことなく垂直に荷重測定素子３８を押
圧する。At this time, in this balance, the horizontal displacement of the knife 32° 32', that is, the suppressor 28, caused by the rotational movement of the levers 16a and 16b is absorbed by the displacement of the ball 34, so that no horizontal force is applied to the load measuring element 38. I won't join. Moreover, since the spheres 34 are arranged in a triangular shape,
The suppressor 28 presses the load measuring element 38 vertically without tilting.

素子１３８には水平方向の力が加わるので測定誤差を生
ずる。この誤差を減少させるにはナイフェツジ１３２，
１３２’とナイフェツジ１３４との高さの差を太きくし
なければならず、こうするとはかり全体の高さが高くな
り、車輪を乗り上げる際に使いにくくなる。そこでこの
型式のはかりでは全体の茜さを１２０−程度とし、測定
誤差を２００分の１程度としたものが使われている。As shown in FIG. 7 (the members indicated by the numbers in these figures correspond to the members shown in FIGS. 1 to 5, the numbers obtained by subtracting 100 from the reference numbers correspond to the members shown in FIGS. 1 to 5), a deep cup-shaped suppressor 128 has a structure in which the load measuring element 138 is pressed through a knife 134 formed on the inner bottom thereof and a receptor 136 having a triangular groove that fits with this knife 3, so that the horizontal direction of the knives 132, 132' The displacement will be absorbed by rotation of the suppressor 128 about the knife blade 134. Since a horizontal force is applied to this load measuring element 138, a measurement error occurs. To reduce this error, the knife 132,
The height difference between the scale 132' and the knife 134 must be widened, which increases the overall height of the scale, making it difficult to use when riding on wheels. Therefore, in this type of scale, the overall degree of madness is set to about 120 -, and the measurement error is set to about 1/200th.
一方本発明はかりは上述の動作をするので、測定誤差は
極めて小さく、シかも浅いカップ状抑圧体を用いること
ができるのではかりの高さを低くシ、使いやすいものと
することができる。On the other hand, since the scale of the present invention operates as described above, the measurement error is extremely small, and since a shallow cup-shaped suppressor can be used, the height of the scale can be kept low and easy to use.
すなわちはかりの高さを１００ｍ程度としながら、測定
誤差を１０００分の１以下にすることができるのである
。なお抑圧体２８の水平方向の変位によシ、梃子１６ｂ
の平面片２６ｂ。In other words, the measurement error can be reduced to 1/1000 or less while the height of the scale is approximately 100 m. Note that depending on the horizontal displacement of the suppressor 28, the lever 16b
flat piece 26b.
２６′ｂがナイフェツジ３２ 、３２’と続する位置は
移動するが、このために生ずる測定誤差は極めて小さい
。Although the position where 26'b is connected to the knives 32, 32' moves, the measurement error caused by this movement is extremely small.
本発明車両用はかりは以上の特徴を有するので、ボータ
プル型として使用するのに最適であるが、据置型にも使
用でき、また車両用以外のはかりにも応用できるなどの
すぐれた特徴がある。Since the vehicle scale of the present invention has the above-mentioned features, it is most suitable for use as a botple type, but it also has excellent features such as being usable as a stationary type and being applicable to scales other than vehicles.
