この考案はゴム、糸巻などの硬度を測定するに

じていた。 As this type of hardness tester, one in which a spindle having a pressure needle at one end is connected to a pressure spring is generally used. The pressure needle is pressed against the article, the spindle is displaced against the pressure of the pressure spring, and this displacement of the spindle is measured as the hardness of the article.
However, in the past, the weight of the spindle and the pressure spring acted on the spindle, and as a result, the measured values varied depending on the orientation of the hardness meter when measuring hardness, for example, downward, upward, or sideways.
この考案は前記従来の欠点を除去し、使用時の
硬度計の向きに関係なく、硬度を的確に測定する
ことができるようにしたものである。 This invention eliminates the drawbacks of the conventional methods and makes it possible to accurately measure hardness regardless of the orientation of the hardness meter during use.
以下、この考案の実施例を図面について説明す
る。 Hereinafter, embodiments of this invention will be described with reference to the drawings.

較正することができる。 In the figure, a spindle 1 has a pressure needle 2 at one end and is housed in a casing 3 so as to be axially displaceable. The pressure needle 2 protrudes a certain distance outside the casing 3, and the other end of the spindle 1 is connected to the pressure spring 4.
is connected to. The spindle 1 is connected to a hardness indicating pointer by means of a rack, pinion, etc. Further, in this embodiment, the pressure spring 4 is engaged with the tip of the adjusting screw 5, and by turning the adjusting screw 5, the position of the spindle 1 can be adjusted and the pointer can be calibrated.

９に均衡せしめられているものである。 The casing 3 has a base plate 7 to which a lever 6 is swingably attached. One end of the lever 6 is engaged with an overhanging rod 8 provided on the spindle 1, and a balance weight 9 is attached to the other end. The distance between the connection point of the lever 6 to the base plate 7, i.e. the fulcrum 10, and the contact point of the spindle 1 to the outrigger rod 8
l 1 , the distance between the fulcrum 10 and the connection point to the balance weight 9 l 2 and the weight W of the balance weight 9
is related to the weight P of the spindle 1 and the pressure spring 4, and is set so that the following equation Pl 1 =Wl 2 holds true. That is, the weights of the spindle 1 and the pressure spring 4 are balanced by the balance weight 9.
前述したようにバランスウエイト９がスピンド
ル１と加圧バネ４の自重に均衡するため、使用時

く硬度を的確に測定することができ、前記従来の
ように硬度計の向きによつて測定値にばらつきが
生じるといつたことがない。 As described above, the balance weight 9 balances the weight of the spindle 1 and pressure spring 4, so whether the hardness tester is facing downward, upward, or sideways during use, the weight of the spindle 1 and pressure spring 4 is offset by the balance weight 9 and has no effect on the spindle 1. Therefore, hardness can be accurately measured regardless of the orientation of the hardness tester, and there has been no variation in the measured values depending on the orientation of the hardness tester as in the conventional method described above.

ばらつきは生じない。 As explained above, in this invention, one end of the lever 6, which is swingably attached to the base plate 7, is connected to the spindle 1, and the other end of the lever 6 is equipped with a balance weight that balances the weight of the spindle 1 and the pressure spring 4. Since the weight 9 is attached, the weight of the spindle 1 and the pressure spring 4 can be offset by the balance weight 9 regardless of the orientation of the hardness meter. Therefore, when measuring the hardness of an article, it is not necessarily necessary to point the hardness meter downward, but it is also possible to turn it upward or sideways and press the pressure needle 2 against the article. Regardless of the orientation of the hardness meter, whether it is facing downwards, upwards or sideways,
The pressure needle 2 is only pressed by the elasticity of the pressure spring 4, and the weight of the spindle 1 and the pressure spring 4 does not act. Therefore, regardless of the orientation of the hardness meter, the hardness of the article can be measured under the same conditions and can be measured accurately. Since the weight of the spindle 1 and the pressure spring 4 does not act, there is no variation in the measured values.
