Articulated work holder for a remote controlled vehicle and the like

An articulated work holder for a fractional dimension, performance vehicle, and the like, comprising:

• a base member operable to engage and to be releasably affixed to a stationary support;
• a first support arm having a first end connected to said base member and a second end projecting away from said base member;
• a second support arm having a first end operably connected to said second end of said first support arm and said second support arm having a second end, said second support arm operably connected to said second end of said first support arm are provided with,
• an adjustable pivot connection operable to permit selective angular adjustment of said second support arm with respect to said first support arm, said second support arm including,
• a first member integral with said first end of said second support arm;
• and
• a second member integral with said second end of said second support arm and said first and second members being operable to interconnect and axially translate with respect to each other;
• and
• a mechanism connected to at least one of said first and second member to selectively lock relative axial translation between said first and second members of said second support arm;
• a third support arm having a first end pivotally connected to said second end of said second support arm and said third support arm having a second end projecting away from said first end;
• a fourth support arm having a first end and a second end and operable extending between a second end of said first support arm and a first end of said second support arm;
• a selectively pivotal connection connecting said second end of said first support arm with said first end of said fourth support arm for selectively setting an angular relationship between said first support arm and said fourth support arm of said articulated work holder;
• and
• a selectively pivotal connection connecting said second end of said fourth support arm with said first end of said second support arm for selectively setting an angular relationship between said fourth support arm and said second support arm of said articulated work holder;
• said base member includes a generally planar base plate;
• and
• a selectively rotatable mounting between said first end of said first support arm and said base member base plate and wherein an imaginary longitudinal axis of said first support arm is approximately normal with respect to said generally planar base plate, said selectively rotatable mounting comprises,
• a collar fixedly mounted upon said generally planar base plate and having a plurality of apertures uniformly spaced about and through the periphery of said collar;
• said first support arm comprises a tubular member having said first end dimensioned to snuggly fit at least one into or around said collar and said first end of said tubular first support arm having at least one set of opposing apertures extending diametrically through said first end of said first support arm such that angular rotation of said first support arm with respect to said collar is operable to bring said at least one set of opposing apertures of said first end of said first support arm into angular registry with opposing apertures of said collar such that a pin may be operable inserted through the opposing apertures of said first support arm and concomitantly through selected opposing apertures of said collar member to lock the angular relationship of said first support arm with respect to said collar and said base of said articulated work holder;
• said first, second and third support arms being composed of tubular members having approximately the same external diameters,
• a fifth support arm having a first end and a second end and being pivotally connected at said first end of said fifth support arm to a lateral portion of said first support arm and being pivotally connected at said second end of said fifth support arm to a lateral portion of said second support arm;
• said fifth support arm comprising at least two members operable to inter-engage and to longitudinally translate with respect to each other;
• and
• means to selectively lock translation of said two members of said fifth support arm such that said fifth support arm operable serve as a supporting brace between the angular relationship of said second support arm with respect to said first support arm of said articulated work holder;
• and
• a vise member connected to said second end of said third support arm and having opposing vehicle contact pads operable to selectively closed or opened with respect to each other to selectively hold a vehicle to be worked on between the contact pads in a desired position for fabrication, maintenance or repair of the fractional dimension, performance vehicle.
