Abstract:
1. A wear member for being connected to an adaptor in turn joined to a fixing member, the wear member being of the type comprising a body with a hollow, cavity or open box in a rear portion thereof for receiving a projecting area or nose projecting from a front portion of an adaptor member, and at least one opening communicating said hollow with the outside for the subsequent introduction of a pin, wherein the hollow, cavity or open box, conjugated with the projecting area or nose of the adaptor, is symmetrical with respect to the vertical axis and comprises: a proximal portion of decreasing cross section ending in a distal portion of continuous cross section, said decreasing section being formed by two decreasing superimposed sections, one having a larger surface than the other one, coinciding in size and shape in the distal portion of the hollow and which in the proximal portion, the smaller surfaced section partially projects at the lower portion of the larger surfaced section such that, along the length of the hollow defined between the proximal portion and the distal portion, the smaller surfaced section projecting at the lower portion of the larger surfaced section is progressively introduced into the larger surfaced section up to a point in which said smaller surfaced section is hidden inside the larger surfaced section, said point being located in the proximal portion, and at least two interlocking surfaces along the proximal portion of the hollow defining the union of the series of smaller surfaced sections with the series of larger surfaced sections.
