Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A solar energy collector comprising an enclosure including an outer peripheral wall having spaced first and second protrusions formed integral therewith, said protrusions having extensions generally parallel to said wall in spaced relation thereto, said first protrusion extension defining the end wall of a channel and terminating in an enlarged formation, a support member affixed to said second protrusion extension and having a supporting surface defining one side wall of said channel, at least one glazing panel within said enclosure, and detachable retainer means for securing said glazing panel in place and comprising a first element mechanically interlocked with said enlarged formation and having a portion defining the other side wall of said channel and overlying the marginal edge of said glazing panel, a sealing member disposed in said channel about the marginal edge of said glazing panel, said retainer means including a second element urging said first element in interlocked relation with said enlarged formation of said first protrusion.
Claim 2
Dependent Claim
160 words
A solar energy collector comprising an enclosure including an outer peripheral wall having spaced first and second protrusions formed integral therewith, said protrusions having extensions generally parallel to said wall in spaced relation thereto, said first protrusion extension defining the end wall of a channel and terminating in an enlarged formation, a support member affixed to said second protrusion extension and having a supporting surface defining one side wall of said channel, at least one glazing panel within said enclosure, and detachable retainer means for securing said glazing panel in place and comprising a first element mechanically interlocked with said enlarged formation and having a portion defining the other side wall of said channel and overlying the marginal edge of said glazing panel, a sealing member disposed in said channel about the marginal edge of said glazing panel, said retainer means including a second element urging said first element in interlocked relation with said enlarged formation of said first protrusion.
Claim 3
Dependent Claim
52 words
A solar energy collector according to claim 1, wherein said first element comprises a unitary one-piece construction of sheet material having a flange constituting said side wall defining portion and a right angularly related leg portion having an enlarged head at the distal end thereof for interlocking engagement with said enlarged formation.
Claim 4
Dependent Claim
31 words
A solar energy collector according to claim 2, including a fluid tight sealant adjacent the free end of said flange disposed in the space between said flange and said glazing panel.
Claim 5
Dependent Claim
52 words
A solar energy collector according to claim 2, wherein said second element comprises a unitary one-piece construction of sheet material having a tongue portion disposed between said leg portion and said enclosure wall with a friction fit therebetween for urging said leg portion head in such interlocked engagement with said enlarged formation.
Claim 6
Dependent Claim
47 words
A solar energy collector according to claim 4, wherein said tongue portion is arcuately curved in transverse cross section to provide a central curved surface in bearing engagement against said leg portion and end portions retreating away from said curved surface and bearing against said enclosure wall.
Claim 7
Dependent Claim
39 words
A solar energy collector according to claim 4, wherein said second element is formed with a lip projecting laterally from one end of said tongue portion and overlying a portion of said first element flange in bearing engagement thereagainst.
Claim 8
Dependent Claim
110 words
A solar energy collector according to claim 1, wherein said first element comprises a unitary one-piece construction of sheet material having a flange overlying the marginal edge of said glazing panel in spaced relation thereto and a right angularly related leg portion having an enlarged head at the distal end thereof adapted to fit behind said enlarged formation of said first protrusion extension for interlocking engagement therewith, said second element comprising a unitary one-piece construction of sheet material having a tongue portion disposed between said leg portion and said enclosure wall with a friction fit therebetween for urging said leg portion head in such interlocked engagement with said enlarged formation.
Claim 9
Dependent Claim
47 words
A solar energy collector according to claim 7, wherein said tongue portion is arcuately curved in transverse cross section to provide a central curved surface in bearing engagement against said leg portion and end portions retreating away from said curved surface and bearing against said enclosure wall.
Claim 10
Dependent Claim
39 words
A solar energy collector according to claim 8, wherein said second element is formed with a lip projecting laterally from one end of said tongue portion and overlying a portion of said first element flange in bearing engagement thereagainst.
