Abstract
(EN)
The present invention is to provide a vernier calliper (100) for measuring linear dimensions of an article. The vernier calliper (100) is having an external jaw (210) including a fixed jaw (110) and a movable jaw (120). The articles for measuring are placed between the fixed jaw (110) and the movable jaw (120). The vernier calliper (100) is also provided with an operating member (130) and a knob (140). The operating member (130) is operably connected to the movable jaw (120) with a gear mechanism (150) therebetween. The operating member (130) is operated manually to move the movable jaw (120) towards and or away from the fixed jaw (110). Further, the knob (140) is arranged on the vernier calliper (100) for changing the direction of movement of the movable jaw (120) upon operating the operating member (130).

La présente invention concerne un pied à coulisse (100) servant à mesurer les dimensions linéaires d'un article. Le pied à coulisse (100) est doté d'une mâchoire externe (210) comprenant une mâchoire fixe (110) et une mâchoire mobile (120). Les articles à mesurer sont placés entre la mâchoire fixe (110) et la mâchoire mobile (120). Le pied à coulisse (100) est également pourvu d'un élément d'actionnement (130) et d'un bouton (140). L'élément d'actionnement (130) est relié fonctionnellement à la mâchoire mobile (120) avec un mécanisme d'engrenage (150) entre eux. L'élément d'actionnement (130) est actionné manuellement pour déplacer la mâchoire mobile (120) vers la mâchoire fixe ou au loin de celle-ci. En outre, le bouton (140) est disposé sur le pied à coulisse (100) pour changer la direction de déplacement de la mâchoire mobile (120) lors de l'actionnement de l'élément d'actionnement (130).
