Definitions

  • the present invention relates to a tool holder frame versatile device to equip a loader, including a front loader for use mounted on a tractor.
  • Such a charger hydraulically controlled, is designed to be able to handle various materials on a farm, such as straw, hay, manure, soil, fertilizer, cereals, beets, apples of soil, of silage, in particular.
  • These tools are in particular skips, claws, grapples, blades, forks, pallet trucks, or combination tools, such as claws for example.
  • the tool holder attached to the end of the loader arms and the back face of the tool (facing towards the loader) have coupling means the design of which allows the quick change of the tool.
  • a difficulty faced by builders and their customers users is that there is no standardization in this area, so that a tool from a given manufacturer is not necessarily adaptable to a loader / tool carrier assembly from another manufacturer.
  • a first standard, marketed under the brand "MAILLEUX”, is characterized in that the tool holder frame comprises a pair of hands identical fastening of approximately “U” section, the opening of which is directed upwards, arranged coaxially and symmetrically on the the vertical and longitudinal plane of the tool holder frame while the dorsal surface of the tool is provided, at the top, with a pair of bars coaxial, thus dimensioned and positioned that each of them can fit and lodge inside a hanging hand.
  • Each bar is mounted between two fittings, one of which extends downwards, and has a locking hole and a notch.
  • the tool frame is equipped with a locking device comprising a pair of pins movable in translation, adapted to be inserted each in one of these orifices, and ensure the attachment of the tool on the tool holder frame.
  • the notch serves as a support zone for the lower part of the tool against stops the tool holder frame.
  • the locking device is controlled manually, using an operating lever, or hydraulically, by means of a cylinder, as described for example in the document FR 2 776 316.
  • a second standard, especially used on the German market, and commonly referred to as “DGS”, is characterized in that the tool carrier comprises a pair of coaxial catch bars arranged symmetrically with both sides of the vertical and longitudinal median plane of the tool holder frame, while that the dorsal surface is provided, in the upper part, with a pair of coaxial hooks, whose opening is directed downwards, thus dimensioned and positioned as each of them can engage on a bar of attachment, and imprison it.
  • the back of the tool has a pair of fittings having a locking hole, and a bearing area for its lower part.
  • the locking holes, and correlatively the pins that penetrate have different diameters; the diameter of these holes is 30 mm for the first standard and 20 mm for the second.
  • a third standard especially used on the Swedish market, and commonly referred to as "SMS" has a structure roughly 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 not constituted by a bore drilled in a fitting, but by a grommet attached to the base of a flat shank whose upper part carries a hook.
  • each hook is therefore in the same vertical and longitudinal plane as a hole of lock, whereas according to the first two standards, the hooking means (bars or hooks) are offset laterally, outwards, with respect to fittings in which the locking holes are drilled.
  • brackets of the second and third standards both in inverted U shape, have different widths; correlatively, the bars latches have different diameters, with a value of 40 mm for the second standard, and 60 mm for the third.
  • the snap bars of the first standard have, for their part, a diameter having a value of 50 mm.
  • the present invention aims to solve these problems incompatibility by proposing a tool-holder frame capable of being coupled to a tool complies with the aforementioned first standard, and at least one of the other two, this the toolholder frame is nevertheless relatively simple in design, returns acceptable, and convenient to use.
  • the invention therefore relates to a tool holder frame for a loader, especially for agricultural use, which includes a pair of hooking hands identical shaped gutter section of approximately shaped section of "U" whose opening is directed upwards, both hands being arranged symmetrically on both sides of the vertical and longitudinal median plane of the frame tool holder, coaxially along a transverse horizontal axis, this tool holder frame being intended to be coupled to a tool satisfying a given mounting standard, said "first standard", whose dorsal face is provided, in the upper part, with a pair coaxial bars, so dimensioned and positioned that each of them can nest and fit inside a hooking hand, so that the tool conform to the first standard is then properly supported by the frame toolbox.
  • the tool holder frame further comprises at least one pair of coaxial coupling bars arranged symmetrically with both sides of the vertical and longitudinal median plane of the tool holder frame, which allow the coupling of the latter to a tool satisfying at least one other standard of assembly, called "second standard", whose dorsal surface is provided, in upper part, of a pair of coaxial hooks, whose opening is directed towards the down, so sized and positioned that each of them can engage on a hanging bar, and imprison it, so that the tool complies with the second standard is then properly supported by the tool holder
