Definitions

  • the aforementioned first plate element comprises an annular line of surface discontinuity on the surface adapted to operate in abutment with the first mechanical member.
  • the surfaces of said plate elements may not be perfectly flat with a consequent decrease in the extension of the abutment surface with the first mechanical member, such a line of discontinuity allows to reduce to the minimum the shift between the abutment surfaces of the first plate element and of the first mechanical member, with the advantage of improving the coupling between these two components.
  • the plate element 10 is adapted, in use, to be clamped against a second plate element 20 adapted to operate in abutment against a second mechanical member (not shown in the figures too) .
  • the surface 10b of the plate element 10 is adapted to operate in abutment with one of the two mechanical members to be clamped (for example a wheel to be clamped onto the hub of a vehicle), while the surface 10'b of the plate element 20 is adapted to operate in abutment with the other mechanical member (for example a nut of a clamping bolt of the wheel at the hub of a vehicle) .
  • the recess 12,12' of each plate element 10,20 acts as a housing seat for the tooth 11,11' of the other plate element when the two plate elements are clamped against one another in the use of the device of the present invention.
  • the recess 22,22' of each plate element acts as a housing seat for the tooth 11, 11' of the other plate element when the various plate elements are stacked on top of one another in packaging, transportation and storage of such plate elements. Therefore, the recesses 12,12' and 22,22' shall also be indicated with the term "seats" in the rest of the present description and in the subsequent claims.

Abstract

La présente invention a pour objet un dispositif d'indication visuelle (1) de l'état de couplage entre deux éléments mécaniques, qui comprend un premier élément en plaque (10) adapté pour fonctionner en butée avec un premier élément mécanique, un second élément en plaque (20) adapté pour être serré contre le premier élément en plaque (10) et un élément élastiquement déformable (3) agencé entre les éléments en plaque mentionnés ci-dessus (10, 20), de manière à ce que lorsque les deux éléments mécaniques se trouvent dans un état de couplage souhaité, l'élément (3) adopte une position lui permettant d'occuper au moins une partie d'un espace à l'extérieur des éléments en plaque mentionnés ci-dessus (10, 20), tandis que lorsque les deux éléments mécaniques se trouvent dans un état de couplage non souhaité, l'élément (3) adopte une position différente, la différence de positionnement de l'élément (3) étant visuellement perceptible par un utilisateur. Au moins un des éléments en plaque mentionnés ci-dessus (10) comprend une dent (11) et l'autre élément en plaque (20) comprend un siège (12') adapté pour loger par engagement ladite dent (11), permettant aux éléments en plaque mentionnés ci-dessus (10, 20) de ne faire plus qu'un.
