Abstract
Abstract A printed circuit board employs a rigid toothed drive arm driven by an exterior spur gear to actuate a pair of levers pivotably attached to one end of the drive arm. Spur gear rotation moves the drive arm and variously moves the drive arm and levers into “Y” or “T” configurations, and in doing so, pushes against exteriorly mounted cabinet or enclosure pins to effect inward and outward motion of the entire board, even when it is fully populated with printed circuit cards contained in cooperatively acting cartridges.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
A circuit board assembly including a mechanism for insertion and removal of said circuit board, said assembly comprising: a circuit board having an electrical connector affixed to a rear edge thereof; a rigid nonconductive base to which said circuit board is affixed; a rigid driving arm disposed as to be forwardly and backwardly moveable within a first slot disposed within said nonconductive base; at least one lever arm pivotably attached to said driving arm and including a pin therein which rides in a second slot disposed substantially perpendicularly to said first slot, said second slot also being disposed within said nonconductive base; and a moving mechanism affixed to said board or base for urging said driving arm in forward and backward directions within said first slot for insertion and removal operation, wherein said lever arm is pivotably moved by said driving arm whereby said lever arm is also capable of engagement with at least one stationary off-board fixture against which force may be exerted by said lever arm for insertion and removal operations.
Claim 2
Dependent Claim
173 words
A circuit board assembly including a mechanism for insertion and removal of said circuit board, said assembly comprising: a circuit board having an electrical connector affixed to a rear edge thereof; a rigid nonconductive base to which said circuit board is affixed; a rigid driving arm disposed as to be forwardly and backwardly moveable within a first slot disposed within said nonconductive base; at least one lever arm pivotably attached to said driving arm and including a pin therein which rides in a second slot disposed substantially perpendicularly to said first slot, said second slot also being disposed within said nonconductive base; and a moving mechanism affixed to said board or base for urging said driving arm in forward and backward directions within said first slot for insertion and removal operation, wherein said lever arm is pivotably moved by said driving arm whereby said lever arm is also capable of engagement with at least one stationary off-board fixture against which force may be exerted by said lever arm for insertion and removal operations.
Claim 3
Dependent Claim
19 words
The assembly of claim 1 in which said first slot is at least partially defined by said nonconductive base.
Claim 4
Dependent Claim
22 words
The assembly of claim 1 in which said first slot at least partially defined by a recess disposed within said nonconductive base.
Claim 5
Dependent Claim
46 words
The assembly of claim 1 in which said driving arm includes a widened portion which is disposed so as to abut portions of said nonconductive base as said drive arm is moved so as to define limits of forward and backward motion for said driving arm.
Claim 6
Dependent Claim
39 words
The assembly of claim 1 in which said driving arm includes a pin which rides in a third slot which is disposed within said nonconductive base, said third slot lying in substantially the same direction as said first slot.
Claim 7
Dependent Claim
27 words
The assembly of claim 1 in which there are present two lever arms pivotably attached to said drive arm at the same point on said drive arm.
Claim 8
Dependent Claim
35 words
The assembly of claim 1 in which said moving mechanism comprises a turnable gear which is affixed to said base or board and which possesses teeth which mesh with corresponding teeth on said drive arm.
Claim 9
Dependent Claim
17 words
The assembly of claim 1 further including a stiffener disposed between said base and said circuit board.
Claim 10
Dependent Claim
15 words
The assembly of claim 8 in which said moving mechanism is affixed to said stiffener.
Claim 11
Dependent Claim
31 words
The assembly of claim 1 in which said base includes recessed portions therein having dimensions which accommodate motion of said lever arm in a plane substantially parallel to said nonconductive base.
