Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
206 words
An amplifier housing comprising: A top heat sink member including oppositely facing first and second lateral walls, each lateral wall having an upper and a lower end, the top member also including a top wall defined by four edges, two oppositely facing edges of the top wall connected to the upper ends and traversing the distance between the lateral walls, the other two oppositely facing edges of the top wall and adjacent edges of the two lateral walls forming front and back open faces, the other two oppositely facing edges being front and back edges of the top heat sink member; and front and back bottom plates, each bottom plate including a bottom section having oppositely facing internal and external edges and oppositely facing first and second lateral edges, the front and back bottom plates also including upright front and back end walls respectively, each end wall extending upwardly from said external edges; whereby, when assembled the bottom sections traverse the distance between the lower ends of the lateral walls, the bottom sections together traversing less than the entire distance between the front and back edges of said top member, the front and back upright end walls substantially blocking said front and back open faces respectively.
Claim 2
Dependent Claim
206 words
An amplifier housing comprising: A top heat sink member including oppositely facing first and second lateral walls, each lateral wall having an upper and a lower end, the top member also including a top wall defined by four edges, two oppositely facing edges of the top wall connected to the upper ends and traversing the distance between the lateral walls, the other two oppositely facing edges of the top wall and adjacent edges of the two lateral walls forming front and back open faces, the other two oppositely facing edges being front and back edges of the top heat sink member; and front and back bottom plates, each bottom plate including a bottom section having oppositely facing internal and external edges and oppositely facing first and second lateral edges, the front and back bottom plates also including upright front and back end walls respectively, each end wall extending upwardly from said external edges; whereby, when assembled the bottom sections traverse the distance between the lower ends of the lateral walls, the bottom sections together traversing less than the entire distance between the front and back edges of said top member, the front and back upright end walls substantially blocking said front and back open faces respectively.
Claim 3
Dependent Claim
24 words
The housing of claim 1 further including at least one foot extension removably secured to a bottom surface of one of said bottom sections.
Claim 4
Dependent Claim
29 words
The housing of claim 2 wherein said at least one extension member includes two pairs of extension members, each pair of extension members connected to a different bottom section.
Claim 5
Dependent Claim
20 words
The housing as recited in claim 3 wherein each of the extension members if formed of an electrically insulating material.
Claim 6
Dependent Claim
30 words
The housing of claim 1 further including at least one middle bottom plate positioned between the front and back bottom plates, a gap existing between each two adjacent bottom plates.
Claim 7
Dependent Claim
29 words
The housing of claim 1 wherein each of the front and back bottom plates traverses approximately half the distance between the front and back edges of said top member.
Claim 8
Dependent Claim
17 words
The housing of claim 3 wherein the extension members are formed of a pliable and resilient material.
Claim 9
Dependent Claim
39 words
The housing of claim 1 wherein the lower end of each lateral wall defines a downwardly facing shelf, the shelves openly facing each other and wherein the bottom sections are sized so as to be received between said shelves.
Claim 10
Dependent Claim
32 words
The housing of claim 1 wherein the bottom plates are secured to the top heat sink member by fastening means between the bottom sections and the lower ends of the lateral walls.
Claim 11
Dependent Claim
25 words
The housing of claim 9 wherein the fastening means are a plurality of screws which extend through the bottom sections and into said lower ends.
