Abstract:
An arm assembly comprising:an arm member comprising: (i) a proximal end adapted for connection to an associated boom for pivoting movement about a transverse pivot axis; (ii) a distal end, spaced from said proximal end along a first longitudinal axis; and, (iii) a first recess defined in said distal end, said first recess defined about a first transverse axis that lies parallel to said transverse pivot axis and including an open mouth and a closed inner end; an implement link member comprising: (i) a first end; and, (ii) a second end spaced from said first end along a second longitudinal axis and defining a second recess about a second transverse axis parallel to said first transverse axis, said second recess having an open mouth and a closed inner end, said first and second recesses adapted for respective receipt of first and second associated pins of an associated implement; and, at least one dude link member having a first end pivotably connected to said distal end of said arm member adjacent said first recess and a second end pivotably connected to said distal end of said implement link member adjacent said second recess, said first end of said dude link member defining a third recess having a mouth that opens in a first direction and said second end of said dude link member defining a fourth recess having a mouth that opens in a second direction that is generally opposite said first direction, said at least one dude link member movable between first and second operative positions in response to movement of said implement link member relative to said arm member wherein: (i) in said first operative position, said mouth of said third recess of said dude link member is at least partially registered with said mouth of said first recess so that said first and third recesses are adapted for receipt of a first pin of an associated implement, and said mouth of said fourth recess is non-registered with said mouth of said second recess; and, (ii) in said second operative position, said mouth of said third recess is non-registered with said mouth of said first recess, and said mouth of said fourth recess is at least partially registered with said mouth of said second recess so that said second and fourth recesses are adapted for receipt of a second pin of an associated implement.
