Abstract
Abstract A panel for use in a sectional door. The panel which is easy to construct and has improved insulating properties, has an elongated insulating core, a first metallic skin on one face of the core and a second metallic skin on the other face of the core. The first and second metallic skins both have crimped edges that are joined together at the sides of the panel with an insulating member interposed between them. The insulating members on the long sides of the panel may include diverging seal arms projecting outwards for providing a seal between adjacent panels. The invention is also directed toward a sectional door incorporating the panels.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A panel for use in a sectional door, said panel comprising: an elongated insulating core having a pair of faces and upper and lower sides; a first metallic skin on one face of said insulating core, said first skin having upper and lower ends crimped back towards themselves to form a first pair of open loops opening toward said first skin; a second metallic skin on the other face of said insulating core, said second skin having upper and lower ends crimped to form a second pair of open loops opening toward said second skin; and an insulating deformable element inserted at said upper and lower sides of said core between said first and second metallic skins to prevent said skins from touching and thus to minimize heat conduction between the same, wherein said first skin is connected to said second skin by hooking said ends of said first pair of open loops into the opening of said second pair of open loops with said insulating element positioned between said ends of said first and second pairs of loops.
Claim 2
Dependent Claim
179 words
A panel for use in a sectional door, said panel comprising: an elongated insulating core having a pair of faces and upper and lower sides; a first metallic skin on one face of said insulating core, said first skin having upper and lower ends crimped back towards themselves to form a first pair of open loops opening toward said first skin; a second metallic skin on the other face of said insulating core, said second skin having upper and lower ends crimped to form a second pair of open loops opening toward said second skin; and an insulating deformable element inserted at said upper and lower sides of said core between said first and second metallic skins to prevent said skins from touching and thus to minimize heat conduction between the same, wherein said first skin is connected to said second skin by hooking said ends of said first pair of open loops into the opening of said second pair of open loops with said insulating element positioned between said ends of said first and second pairs of loops.
Claim 3
Dependent Claim
47 words
A panel as claimed in claim 1, wherein the first and second metallic skins are connected together both at one long side of the core adjacent one face of said core, and at the other long side of the core adjacent the other face of said core.
Claim 4
Dependent Claim
33 words
A panel as claimed in claim 2, wherein each insulation element on the long sides of the panel has sealing means projecting from one end outwardly of the long side of the core.
Claim 5
Dependent Claim
35 words
A panel as claimed in claim 3, wherein said sealing means comprises a pair of diverging sealing arms projecting form the external end of the insulation element outwardly of the long side of the core.
Claim 6
Dependent Claim
193 words
A sectional door comprising a plurality of elongate panels hingedly connected together at their long side, each of said panels comprising: an elongated insulating core having a pair of faces and upper and lower sides; a first metallic skin on one face of said insulating core, said first skin having upper and lower ends crimped back towards themselves to form a first pair of open loops opening toward said first skin; a second metallic skin on the other face of said insulating core, said second skin having upper and lower ends crimped back towards themselves to form a second pair of open loops opening toward said second skin; and an insulating deformable element inserted at said upper and lower sides of said core between said first and second metallic skins to prevent said skins from touching and thus to minimize heat conduction between the same, wherein said first skin is connected to said second skin by said ends of said first pair of open loops being hooked into the opening of said second pair of open loops with said insulating element positioned between said ends of said first and second pairs of loops.
Claim 7
Dependent Claim
193 words
A sectional door comprising a plurality of elongate panels hingedly connected together at their long side, each of said panels comprising: an elongated insulating core having a pair of faces and upper and lower sides; a first metallic skin on one face of said insulating core, said first skin having upper and lower ends crimped back towards themselves to form a first pair of open loops opening toward said first skin; a second metallic skin on the other face of said insulating core, said second skin having upper and lower ends crimped back towards themselves to form a second pair of open loops opening toward said second skin; and an insulating deformable element inserted at said upper and lower sides of said core between said first and second metallic skins to prevent said skins from touching and thus to minimize heat conduction between the same, wherein said first skin is connected to said second skin by said ends of said first pair of open loops being hooked into the opening of said second pair of open loops with said insulating element positioned between said ends of said first and second pairs of loops.
Claim 8
Dependent Claim
51 words
A sectional door as claimed in claim 5, wherein the first and second metallic skins of each panel are connected together at one long side of the core adjacent the one face of the core, and at the other long side of the core adjacent the other face of the core.
Claim 9
Dependent Claim
67 words
A sectional door as claimed in claim 6, wherein each insulation element on the long sides of the panel has sealing means projecting from one end outwardly of the long side of the panel to abut the long side of an adjacent panel when the door is closed, said sealing means including a pair of diverging sealing arms projecting from the external end of each insulation element.
Claim 10
Dependent Claim
34 words
A panel as claimed in claims 1 or 5, wherein each insulation element has means for sealing against an adjacent panel projecting from one end thereof outwardly of the long side of the core.
