Abstract
Abstract A printed circuit card retainer and rack assembly is described. The retainers comprise resilient arcuate channel members of chamfered U-shaped cross section permitting vertical alignment of cards of diverse thickness. The retaining force exerted by the resiliency and deformation of the members is in the direction parallel to the face of the card.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
86 words
A printed circuit card rack having parallel support members joined to end plates forming a solid cage, a plurality of card retainers held between adjacent support members and disposed in spaced relation between opposite support members for accommodating a card between a pair of oppositely disposed retainers, each of said retainers comprising resilient channel members of arcuate shape slideably accepting a card for retention by the force exerted due to the rectilinear distortion of the arcuation of said members effected by the presence of said card.
Claim 2
Dependent Claim
86 words
A printed circuit card rack having parallel support members joined to end plates forming a solid cage, a plurality of card retainers held between adjacent support members and disposed in spaced relation between opposite support members for accommodating a card between a pair of oppositely disposed retainers, each of said retainers comprising resilient channel members of arcuate shape slideably accepting a card for retention by the force exerted due to the rectilinear distortion of the arcuation of said members effected by the presence of said card.
Claim 3
Dependent Claim
86 words
A printed circuit card rack having parallel support members joined to end plates forming a solid cage, a plurality of card retainers held between adjacent support members and disposed in spaced relation between opposite support members for accommodating a card between a pair of oppositely disposed retainers, each of said retainers comprising resilient channel members of arcuate shape slideably accepting a card for retention by the force exerted due to the rectilinear distortion of the arcuation of said members effected by the presence of said card.
Claim 4
Dependent Claim
86 words
A printed circuit card rack having parallel support members joined to end plates forming a solid cage, a plurality of card retainers held between adjacent support members and disposed in spaced relation between opposite support members for accommodating a card between a pair of oppositely disposed retainers, each of said retainers comprising resilient channel members of arcuate shape slideably accepting a card for retention by the force exerted due to the rectilinear distortion of the arcuation of said members effected by the presence of said card.
Claim 5
Dependent Claim
56 words
A printed circuit card rack in accordance with claim 1 wherein said channel members terminate in flat end portions adapted to be bent over slots provided in said support members, said slots being of sufficient width to permit axial movement of said members upon rectilinear distortion of their arcuation, due to the insertion of a card.
Claim 6
Dependent Claim
33 words
A printed circuit card rack in accordance with claim 1 wherein said channel members have an angularly chamfered U-shaped cross sectional configuration for the vertical center line alignment of cards of diverse thickness.
