Claim 4

Dependent Claim 79 words

The printed circuit card retainer according to claim 2, wherein: said channel having a first side wall, a second side wall, and a bottom wall and a dovetail cross-section, said channel side walls being inclined so that the width of the channel is greater at the channel bottom wall than at the channel opening; and said extrusion is dovetail shaped having side walls which are inclined so that the width of the extrusion increases away from said retainer post.

Claim 5

Dependent Claim 156 words

The printed circuit card retainer according to claim 1, wherein: said elongated retaining post is of rectangular cross-section and includes teeth formed into two opposing sides of said retaining post; said clamp assembly includes a rectangular opening equivalent in dimensions to the rectangular cross section of said retainer post, said rectangular opening being centrally located in the body of the clamp assembly and extending through the clamp assembly body permitting the clamp to be placed over and situated at any position along said retainer post; and said clamp assembly further including two moveable paws located on first and second opposing sides of said clamp assembly body, each one of said paws including teeth which are urged into engagement with the teeth along the sides of said retainer post, each one of said paws also including a lever arm which permits disengaged of the paw teeth from the teeth formed along the sides of said retainer post.

Claim 6

Dependent Claim 63 words

The printed circuit card retainer according to claim 4, wherein said means for engaging the top edge of said circuit card comprises: an extended section extending out from a third side of the clamp assembly body, said extended section including a card receiving notch formed into a bottom surface of said extended section for containing the top edge of said printed circuit card.

Claim 7

Dependent Claim 31 words

The printed circuit card retainer according to claim 1, wherein: said base member includes an adhesive strip for attaching said base member to the side of said circuit card edge connector.

Claim 8

Dependent Claim 234 words

An adjustable retainer for retaining a printed circuit card in a circuit card edge connector, said printed circuit card including a bottom edge for connection with said circuit card edge connector and a top edge opposite said bottom edge, said retainer comprising: an elongated base member for attachment to said circuit card edge connector, said base member including a channel formed along a length of said base, said base member being attached along a side of said circuit card edge connector with said channel opening away from said circuit card edge connector; an elongated retaining post, said post including an extrusion extending out from one side of said retaining post near a first end of said retainer post, said extrusion and channel being formed to permit slideable engagement of said extrusion within said channel, wherein said retaining post is secured in an orthogonal relationship with said circuit card edge connector and parallel with said circuit card installed into said circuit card edge connector, said extrusion and channel permitting attachment of said retaining post to said base member at various positions along the side of said circuit card edge connector; and a clamp assembly slideably attached to said retaining post for engaging the top edge of said circuit card and positionable at various positions along said retaining post, wherein said clamp assembly is capable of being secured into a selected position along said retainer post.

Claim 9

Dependent Claim 234 words

An adjustable retainer for retaining a printed circuit card in a circuit card edge connector, said printed circuit card including a bottom edge for connection with said circuit card edge connector and a top edge opposite said bottom edge, said retainer comprising: an elongated base member for attachment to said circuit card edge connector, said base member including a channel formed along a length of said base, said base member being attached along a side of said circuit card edge connector with said channel opening away from said circuit card edge connector; an elongated retaining post, said post including an extrusion extending out from one side of said retaining post near a first end of said retainer post, said extrusion and channel being formed to permit slideable engagement of said extrusion within said channel, wherein said retaining post is secured in an orthogonal relationship with said circuit card edge connector and parallel with said circuit card installed into said circuit card edge connector, said extrusion and channel permitting attachment of said retaining post to said base member at various positions along the side of said circuit card edge connector; and a clamp assembly slideably attached to said retaining post for engaging the top edge of said circuit card and positionable at various positions along said retaining post, wherein said clamp assembly is capable of being secured into a selected position along said retainer post.
