Definitions

  • the present invention relates to a versatile toolholder frame intended to equip a loader, including a front loader for agricultural use mounted on a tractor.
  • Such a hydraulically operated loader is designed to handle various materials on a farm, such as straw, hay, manure, soil, fertilizer, cereals, beets, potatoes , silage, in particular.
  • These tools are in particular skips, claws, grapples, blades, forks, pallet trucks, or combined tools, such as clamshells, for example.
  • the tool holder frame attached to the end of the loader arms and the back face of the tool (face facing the loader) have complementary coupling means whose design allows the rapid change of the tool.
  • a difficulty encountered by manufacturers and their user customers lies in the fact that there is no standardization in the field, so that a tool from a given manufacturer is not necessarily adaptable on a loader assembly / tool holder frame from another manufacturer.
  • a first standard, marketed under the trademark "MAILLEUX”, is characterized in that the tool holder frame comprises a pair of identical hooking hands of approximately “U” -shaped section, whose opening is directed upwards, arranged coaxially and symmetrically on both sides of the vertical and longitudinal median plane of the tool frame, while the dorsal surface of the tool is provided, at the top, with a pair of bars coaxial, so dimensioned and positioned that each of them can fit and be housed inside a gripping hand.
  • Each bar is mounted between two fittings, one of which extends downwards, and has a locking hole and a notch.
  • the tool-holder frame is equipped with a locking device comprising a pair of pins movable in translation, each adapted to fit into one of these orifices, and ensuring the attachment of the tool to the frame-holder tool.
  • the notch serves as a bearing area of the lower part of the tool against appropriate stops which is provided with the tool holder frame.
  • the locking device is controlled manually, using an operating lever, or hydraulically, by means of a jack, as described for example in the document FR 2,776,316 which describes a tool holder according to the preamble of claim 1.

  • the locking holes, and correlatively the pins that penetrate have different diameters; the diameter of these orifices is 30 mm for the first standard and 20 mm for the second.
  • a third standard particularly used on the Swedish market, and commonly referred to as "SMS" has a structure similar to that of the second standard, the bars being carried by the tool holder frame, and the hooks by the tool.
  • each of the locking holes is constituted not by a bore drilled in a fitting, but by an eyelet fixed to the base of a flat rod whose upper part carries a hook.
  • each hook is therefore in the same vertical and longitudinal plane as an orifice of locking, while according to the first two standards, the hooking means (bars or hooks) are offset laterally outwardly relative to the fittings in which are drilled the locking holes.
