Hinge for extended grabber tool

An improvement for elongate tools that are designed to engage objects from remote distances and more particularly those tool that have engagement elements located on a distal end of a first rod, a handle on a proximate end of second rod, a controller on said handle to control said engagement elements, and a linkage between said controller and said engagement elements to control said engagement elements,

• said improvement comprising providing a two part rod, said rod connected together by a locking hinge, said locking hinge located at a medial position between said engagement means and said handle means, and said locking hinge further comprising:
• a first hinge segment comprising a leaf section and opposite first knuckle sections, said first knuckle sections located a predetermined distance apart, said leaf section adapted to be affixed to said distal end of said rod,
• a second hinge segment said second segment also comprising a leaf section and opposite second knuckle section oriented a predetermined distance apart, said leaf section adapted to be affixed to said proximal end of said rod,
• said first and second knuckles comprising planar annular sections oriented parallel with a line formed by said first and said second rods, and said first and said knuckles aligned directly adjacent to one another comprising a first knuckle pair and a second knuckle pair and said knuckle pairs defining a central aperture, said aperture defining an opening that is not round,
• wherein said first and said second knuckle pairs are positioned a predetermined distance apart from one another thereby defining a central gap, said central gap having a width a distance, and
• and a locking pin, said locking pin adapted to be received by said knuckles and further comprising a plurality of axial segments, each segment having a with the same distance as said gap and wherein a number of said segments are round and spaced the same distance apart from one another as the distance separating said knuckles on said second hinge segment and the remainder of said segments have an axial section that are round and can closely fit into the apertures formed by said knuckles,
• wherein said locking pin can be moved in rectilinear fashion into a first locked position wherein said no-round axial profiled sections of said locking pin are aligned with the apertures in said corresponding knuckles and a second free position wherein said round axial sections are aligned with said apertures in said knuckles and thereby provide for limited rotational movement.
