Abstract
Abstract A tool for inserting a printed circuit card into a holder the latter having top and bottom tracks and a rear wall having contacts engageable by terminal tabs on the card, comprising a pistol grip type handle and a shaft extending perpendicularly outward from the handle. The shaft includes a hook on one end with an opposite end mounted to the handle. A plunger is slideably mounted on the shaft and is propelled forward via a spring loaded trigger bracket. With the hook engaged to the bottom guide track the plunger is used to push and insert the card into the holder when the trigger bracket is squeezed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A manipulator for facilitating the insertion of a printed circuit card into a holder, the latter having top and bottom parallel card guides, each card guide including at least one transversely oriented guide track having respective lateral card edges resting therein, said manipulator comprising: a first member having a shaft projecting outwardly perpendicular to said first member and said shaft terminating in an hooked end, said hooked end arranged to engage said bottom card guide adjacent said circuit card; plunger means slideably mounted to said shaft and moveable along said shaft, including a front face arranged to rest against a transverse edge of said circuit card; lever means rotatably mounted to said first member and including first and second sections, said first section in communication with said plunger means and said second section disposed to have manual pressure applied thereto urging said second section toward said first member and said first section in response to said pressure moving said plunger away from said first member thereby applying a force to said circuit card and inserting said card into said holder.
Claim 2
Dependent Claim
180 words
A manipulator for facilitating the insertion of a printed circuit card into a holder, the latter having top and bottom parallel card guides, each card guide including at least one transversely oriented guide track having respective lateral card edges resting therein, said manipulator comprising: a first member having a shaft projecting outwardly perpendicular to said first member and said shaft terminating in an hooked end, said hooked end arranged to engage said bottom card guide adjacent said circuit card; plunger means slideably mounted to said shaft and moveable along said shaft, including a front face arranged to rest against a transverse edge of said circuit card; lever means rotatably mounted to said first member and including first and second sections, said first section in communication with said plunger means and said second section disposed to have manual pressure applied thereto urging said second section toward said first member and said first section in response to said pressure moving said plunger away from said first member thereby applying a force to said circuit card and inserting said card into said holder.
Claim 3
Dependent Claim
46 words
A manipulator as defined in claim 1, wherein: said first member is comprised of a rectangular handle having a square cross section and having said shaft extending outwardly perpendicular from one face of the upper portion of said handle and said shaft hooked end extending downwardly.
Claim 4
Dependent Claim
60 words
A manipulator as defined in claim 1, wherein: said plunger is rectangularly shaped including a longitudinal bore running through said plunger arranged to accept said shaft therein allowing said plunger to be moveable along said shaft, said plunger further including a vertically oriented notch on one face thereof adjacent said handle arranged to accept said lever means first section therein.
Claim 5
Dependent Claim
60 words
A manipulator as defined in claim 1, wherein: said lever means second section is comprised of a triangularly shaped trigger said trigger rotatably mounted to two opposite faces of said handle and having a vertical upstanding leg extending from said trigger forming said lever means first section, said trigger including a wire spring biasing said trigger away from said handle.
Claim 6
Dependent Claim
35 words
A manipulator as defined in claim 1, wherein: said plunger front face includes a vertically oriented channel situated off center on said front face and arranged to receive an edge of said circuit card therein.
