Abstract
Abstract Disclosed is an insulated metal roofing system which includes channel shaped roofing panels locked together in side-by-side relationship at the upwardly projecting edges of the channel legs by means of interlocking flanges, with legs of adjacent panels in abutting relationship. In some embodiments specially configured clip members engage the roofing panels in their regions of abutment and project downwardly therefrom. Channel shaped ceiling panels are hung in side-by-side relationship on the clip members, and part or all of the space between the roofing panels and the ceiling panels is filled with insulation. The clip members are preferably constructed to provide a selection of points of connection between them and the ceiling panels to thereby provide a selection of spacings between the roofing panels and the ceiling panels. In another embodiment, the ceiling panels are connected directly to the roofing panels.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
150 words
An insulatable metal roofing structure comprising: channel shaped roofing members having upstanding side legs with interlockable flanges formed at their upper ends for interlocking a series of said panels together in side-by-side relationship; said roofing members being of selected substantially uniform width; said roofing member legs having outwardly facing detent grooves formed therein and positioned to establish a tube-like detent space between adjacent interlocked roofing members; channel shaped ceiling panels having upstanding side legs, said panels being of a width such that the legs of a ceiling panel are substantially alignable with legs of superjacent roofing members; and ceiling panel suspension means including an element penetrating between legs of adjacent interlocked roofing members from below to detent lock in said detent space to thereby suspend said ceiling panels a selected distance beneath said roofing members, whereby a volume for accommodating insulation above the ceiling and beneath the roof is established.
Claim 2
Dependent Claim
150 words
An insulatable metal roofing structure comprising: channel shaped roofing members having upstanding side legs with interlockable flanges formed at their upper ends for interlocking a series of said panels together in side-by-side relationship; said roofing members being of selected substantially uniform width; said roofing member legs having outwardly facing detent grooves formed therein and positioned to establish a tube-like detent space between adjacent interlocked roofing members; channel shaped ceiling panels having upstanding side legs, said panels being of a width such that the legs of a ceiling panel are substantially alignable with legs of superjacent roofing members; and ceiling panel suspension means including an element penetrating between legs of adjacent interlocked roofing members from below to detent lock in said detent space to thereby suspend said ceiling panels a selected distance beneath said roofing members, whereby a volume for accommodating insulation above the ceiling and beneath the roof is established.
Claim 3
Dependent Claim
41 words
A roofing structure in accordance with claim 1 in which said ceiling panels have a width substantially equal to the width of a roofing member, thereby establishing said alignability of ceiling panel legs with roofing panel legs on a one-panel-for-one-member basis.
Claim 4
Dependent Claim
32 words
A roofing structure in accordance with claim 1 in which said ceiling panel suspension means comprise downturned detent flanges on the legs of said ceiling panels detent lockable in said detent space.
Claim 5
Dependent Claim
51 words
A roofing structure in accordance with claim 1 in which said ceiling panel suspension means comprise clip members having detent locking means thereon for penetrating between legs of adjacent interlocked roofing members to detent lock in said detent space, and further having means engaging the upturned legs of a ceiling panel.
Claim 6
Dependent Claim
18 words
A roofing structure in accordance with claim 4 in which said clip members are formed of insulative material.
Claim 7
Dependent Claim
49 words
A roofing structure in accordance with claim 4 in which said clip members are provided with a plurality of vertically spaced ceiling panel leg engaging means, thereby enabling the distance between roofing members and ceiling panels to be selectively established during the course of installation of said roofing structure.
Claim 8
Dependent Claim
21 words
A roofing structure in accordance with claim 4 in which said ceiling panel leg engaging means comprise outwardly extending detent flanges.
Claim 9
Dependent Claim
62 words
A roofing structure in accordance with claim 4 in which said clip members are substantially H-shaped in profile, the bar of said "H" having a width sufficient to span the underside of a roofing member, the upstanding legs of said "H" having said detent locking means thereon, and the depending legs of said "H" having said ceiling panel leg engaging means thereon.
Claim 10
Dependent Claim
45 words
A roofing structure in accordance with claim 4 in which said clip members are substantially I-shaped in profile, the upper portion of said "I" having said detent locking means thereon, and the lower portion of said "I" having said ceiling panel leg engaging means thereon.
Claim 11
Dependent Claim
101 words
A roofing structure in accordance with claim 1 and further comprising skylight means comprising: an elongated skylight roofing panel formed of light transmitting material and having detent locking means formed along the longitudinal edges thereof for engagement with the interlocking flanges on the legs of said roofing members; a pair of elongated skylight ceiling panel support elements each engaging one of said ceiling panel suspension means, said support elements each having a horizontally projecting flange; and a substantially planar skylight ceiling panel formed of light transmitting material supported on said horizontally projecting flanges along opposed edges of said skylight ceiling panel.
Claim 12
Dependent Claim
135 words
An insulatable metal roofing structure comprising: channel shaped roofing members having upstanding side legs with interlockable flanges formed at their upper ends for interlocking a series of said panels together in side-by-side relationship; said roofing members being of selected substantially uniform width; said roofing member legs having outwardly facing attachment means formed therein; channel shaped ceiling panels having upstanding side legs, said panels being of a width such that the legs of a ceiling panel are substantially alignable with legs of superjacent roofing members; and ceiling panel suspension means including an element penetrating between legs of adjacent interlocked roofing members from below to engage said attachment means to thereby suspend said ceiling panels a selected distance beneath said roofing members, whereby a volume for accomodating insulation above the ceiling and beneath the roof is established.
Claim 13
Dependent Claim
135 words
An insulatable metal roofing structure comprising: channel shaped roofing members having upstanding side legs with interlockable flanges formed at their upper ends for interlocking a series of said panels together in side-by-side relationship; said roofing members being of selected substantially uniform width; said roofing member legs having outwardly facing attachment means formed therein; channel shaped ceiling panels having upstanding side legs, said panels being of a width such that the legs of a ceiling panel are substantially alignable with legs of superjacent roofing members; and ceiling panel suspension means including an element penetrating between legs of adjacent interlocked roofing members from below to engage said attachment means to thereby suspend said ceiling panels a selected distance beneath said roofing members, whereby a volume for accomodating insulation above the ceiling and beneath the roof is established.
Claim 14
Dependent Claim
41 words
A roofing structure in accordance with claim 11 in which said ceiling panels have a width substantially equal to the width of a roofing member, thereby establishing said alignability of ceiling panel legs with roofing panel legs on a one-panel-for-one-member basis.
Claim 15
Dependent Claim
51 words
A roofing structure in accordance with claim 11 in which said ceiling panel suspension means comprise clip members having detent locking means thereon for penetrating between legs of adjacent interlocked roofing members to detent lock with said attachment means, and further having means engaging the upturned legs of a ceiling panel.
