Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
350 words
An electronic circuit card cage including two end plates, spaced-apart first and second upper support members adjustably secured between said end plates, said first and second upper support members each having a horizontal upper connector wall, both said upper connector walls lying in a first common horizontal plane, first arcuate bridges formed on said upper connector walls of said first and second upper support members and defining therewith spaces into which members can be inserted, said arcuate bridges being spaced apart on the length of said upper connector walls, each arcuate bridge on one upper connector wall being aligned with an arcuate bridge on the other upper connector wall, spaced-apart first and second lower support members adjustably secured between said end plates, said first and second lower support members each having a horizontal lower connector wall, both said lower connector walls lying in a second common horizontal plane, second arcuate bridges formed on said lower connector walls of said first and second lower support members and defining therewith spaces into which members can be inserted, said arcuate bridges being spaced apart on the length of said lower connector walls, each second arcuate bridge on one lower connector wall being aligned with an arcuate bridge on the other lower connector wall, said first and second horizontal planes being spaced from each other and defining a space within which electronic circuit cards can be positioned, and first channel-shaped elongated card-support members coupled between said first and second upper support members, and second channel-shaped elongated card-support members coupled between said first and second lower members, all of said first and second channel-shaped members having end portions which enter the spaces formed by and engage said arcuate bridges whereby each channel-shaped member can be secured in place between aligned arcuate bridges on a first and on a second upper or lower support member, each first channel-shaped member being disposed vertically above a second channel-shaped member with the first member facing down and the second member facing up so that an electronic circuit card can be inserted between them and supported in their facing channels.
Claim 2
Dependent Claim

An electronic circuit card cage including two end plates, spaced-apart first and second upper support members adjustably secured between said end plates, said first and second upper support members each having a horizontal upper connector wall, both said upper connector walls lying in a first common horizontal plane, first arcuate bridges formed on said upper connector walls of said first and second upper support members and defining therewith spaces into which members can be inserted, said arcuate bridges being spaced apart on the length of said upper connector walls, each arcuate bridge on one upper connector wall being aligned with an arcuate bridge on the other upper connector wall, spaced-apart first and second lower support members adjustably secured between said end plates, said first and second lower support members each having a horizontal lower connector wall, both said lower connector walls lying in a second common horizontal plane, second arcuate bridges formed on said lower connector walls of said first and second lower support members and defining therewith spaces into which members can be inserted, said arcuate bridges being spaced apart on the length of said lower connector walls, each second arcuate bridge on one lower connector wall being aligned with an arcuate bridge on the other lower connector wall, said first and second horizontal planes being spaced from each other and defining a space within which electronic circuit cards can be positioned, and first channel-shaped elongated card-support members coupled between said first and second upper support members, and second channel-shaped elongated card-support members coupled between said first and second lower members, all of said first and second channel-shaped members having end portions which enter the spaces formed by and engage said arcuate bridges whereby each channel-shaped member can be secured in place between aligned arcuate bridges on a first and on a second upper or lower support member, each first channel-shaped member being disposed vertically above a second channel-shaped member with the first member facing down and the second member facing up so that an electronic circuit card can be inserted between them and supported in their facing channels.
Claim 3
Dependent Claim
64 words
The apparatus defined in claim 1 wherein each channel-shaped member includes a channel portion and said end portions, said end portions being offset from the channel portion between them whereby, when said channel-shaped members are coupled to said support members, they are disposed below the upper support members and above the lower support members so that circuit cards can be inserted between them freely.
