Claim 3

The latching lever of claim 1 further including an arm portion, close to said pivot point, for engaging the mating apparatus during entry thereinto, for aiding said entry, and for blocking the removal of said object until said lever is pivoted to an alternate position.

Claim 4

The latching lever of claim 2 wherein said body portion, proximate said pivot point, defines a surface for engaging the mating apparatus during the removal of said object for aiding said removal.

Claim 5

A latching lever for use with a piece of sheet material for aiding the entry of said piece into a mating apparatus, for securing said piece in said mating apparatus, and for aiding the removal of said piece from said mating apparatus, said latching lever characterized by: a body portion for pivotal connection to said object, about a pivot point; a hooked portion, flexibly mounted to said body portion, and projecting therefrom at the end of said body portion remote from said pivot point, for engaging a projection attached to said piece; an actuating member, solidly connected to said hooked portion and protruding therefrom, for moving said hooked portion relative to said body portion, so as to selectively disengage said hooked portion from said projection; a stop portion, solidly connected to said body portion and protruding therefrom, located adjacent said actuating member, but spaced therefrom so as to provide a limit to the movement of said actuating member; an arm portion protruding from said body portion, close to said pivot point, for engaging said mating apparatus during entry thereinto, for aiding said entry, and for blocking the removal of said piece until said lever is pivoted to an alternate position.

Claim 6

A latching lever for use with a piece of sheet material for aiding the entry of said piece into a mating apparatus, for securing said piece in said mating apparatus, and for aiding the removal of said piece from said mating apparatus, said latching lever characterized by: a body portion for pivotal connection to said object, about a pivot point; a hooked portion, flexibly mounted to said body portion, and projecting therefrom at the end of said body portion remote from said pivot point, for engaging a projection attached to said piece; an actuating member, solidly connected to said hooked portion and protruding therefrom, for moving said hooked portion relative to said body portion, so as to selectively disengage said hooked portion from said projection; a stop portion, solidly connected to said body portion and protruding therefrom, located adjacent said actuating member, but spaced therefrom so as to provide a limit to the movement of said actuating member; an arm portion protruding from said body portion, close to said pivot point, for engaging said mating apparatus during entry thereinto, for aiding said entry, and for blocking the removal of said piece until said lever is pivoted to an alternate position.

Claim 7

The latching lever of claim 4 wherein said body portion, proximate said pivot point, defines a surface for engaging the mating apparatus during the removal of said piece for aiding said removal.

Claim 8

The latching lever of claim 5 wherein said piece of sheet material is a printed circuit board.

Claim 9

The latching lever of claim 4, 5 or 6 wherein said lever partially straddles one corner of said piece of sheet material such that at least said hooked portion, said pivot point, and said arm portion are each at least partially bisected by an opening in said lever into which at least one edge of said piece of sheet material protrudes when said latching lever is in its latched position.

Claim 10

The combination of a printed circuit board (PCB) and a latching lever for use in aiding the entry of said PCB into a mating apparatus, for securing said PCB in said mating apparatus, and for aiding the removal of said PCB from said mating apparatus, said combination characterized by: a printed circuit board; at least one latching lever pivotally connected to said printed circuit board; at least one stud attached to said PCB, and protruding from both planar surfaces of said PCB, for engaging said lever, one stud for each said lever; said latching lever comprising: a body portion for pivotal connection to said PCB, about a pivot point; a hooked portion, flexibly mounted to said body portion, and projecting therefrom at the end of said body portion remote from said pivot point, for selectively engaging said stud; an actuating member, solidly connected to said hooked portion and protruding therefrom, for moving said hooked portion relative to said body portion, so as to selectively disengage said hooked portion from said stud; a first stop portion, solidly connected to said body portion and protruding therefrom, located adjacent said actuating member, but spaced therefrom so as to provide a limit to the movement of said actuating member; a second stop portion, solidly connected to said body portion and protruding therefrom, located adjacent said hooked portion, but spaced therefrom so as to provide a limit to the movement of said hooked portion; an arm portion protruding from said body portion, close to said pivot point, for engaging said mating apparatus during entry thereinto, for aiding said entry, and for blocking the removal of said piece until said lever is pivoted to an alternate position.

Claim 11

The combination of a printed circuit board (PCB) and a latching lever for use in aiding the entry of said PCB into a mating apparatus, for securing said PCB in said mating apparatus, and for aiding the removal of said PCB from said mating apparatus, said combination characterized by: a printed circuit board; at least one latching lever pivotally connected to said printed circuit board; at least one stud attached to said PCB, and protruding from both planar surfaces of said PCB, for engaging said lever, one stud for each said lever; said latching lever comprising: a body portion for pivotal connection to said PCB, about a pivot point; a hooked portion, flexibly mounted to said body portion, and projecting therefrom at the end of said body portion remote from said pivot point, for selectively engaging said stud; an actuating member, solidly connected to said hooked portion and protruding therefrom, for moving said hooked portion relative to said body portion, so as to selectively disengage said hooked portion from said stud; a first stop portion, solidly connected to said body portion and protruding therefrom, located adjacent said actuating member, but spaced therefrom so as to provide a limit to the movement of said actuating member; a second stop portion, solidly connected to said body portion and protruding therefrom, located adjacent said hooked portion, but spaced therefrom so as to provide a limit to the movement of said hooked portion; an arm portion protruding from said body portion, close to said pivot point, for engaging said mating apparatus during entry thereinto, for aiding said entry, and for blocking the removal of said piece until said lever is pivoted to an alternate position.

Claim 12

The combination of claim 8 wherein said latching lever partially straddles one corner of said printed circuit board (PCB) such that at least said hooked portion, said pivot point, and said arm portion are each at least partially bisected by an opening in said lever into which at least one edge of said PCB protrudes when said latching lever is in its latched position.
