Description
(54) INSULATED SECTIONAL DOOR
(71) We, P. C. HENDERSON GROUP LIMITED, a British Company, of
Romford, Essex, RM3 8UL, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to insulated sectional doors having panel sections hingedly interconnected at horizontal adjacent edges.
Generally such doors are movable, in a manner similar to a roll top desk lid, into and out of a closed position in which outer skins of the panel sections are aligned to present a substantially continuous vertical outer surface to the door, by pivotal movement of the panel sections in turn about their hinged horizontal edges in response to panel displacement in the plane of their outer skins and perpendicular to their hinged horizontal edges.
Although it has been proposed to insulate such doors by the insertion of blocks of plastics insulating material between inner and outer skins of the panel sections this manner of construction can require many time-consuming separate manufacturing steps and results in panel sections in which the blocks make little or no contribution to the overall strength of the panel sections. There is, therefore, a need for an improved insulated sectional door.
Accordingly the present invention pr.ovides an insulated sectional door having hingedly interconnected panel sections, wherein at least one panel section has an inner skin, a superimposed outer skin laterally spaced therefrom, plastics edge members closing spaces defined between spaced adjacent edges of the superimposed skins, and plastics insulating material foamed in situ in the space between the skins and edge members and bonded to the skins and edge members.
Preferably the plastics insulating material is polyurethane foam. Advantageously at least one of the skins is made from substantially rigid sheet material, preferably metal. The plastics edge members may be made of polyvinyl chloride, preferably by extrusion, and
conveniently are channel shaped in cross
section and formed to incorporate seal
elements.
For a better understanding of the present
invention and to show how the same may be
carried into effect, reference will now be
made, by way of example, to the accompanying
drawings in which: Fig. 1 is a vertical section of part of an
insulated sectional door according to one
embodiment of the invention, shown in a closed
position,
Fig. 2 is a horizontal section from above
of part of the embodiment of Fig. 1, and
Fig. 3 is a horizontal section from above
of a detail alternative of part of the
embodiment of Fig. 2.
As shown in the drawings, the insulated
sectional door embodiment illustrated has panel sections generally indicated at 1, interconnected by hinges 2. At least one panel
section 1 has an inner skin 3 and a superimpose outer skin 4. Plastics edge members, such as top edge member 5, bottom edge member 6 and end edge members 7 close spaces defined between spaced adjacent edges of the superimposed skins 3 and 4. Plastics insulating material 8, preferably polyurethane, is foamed in situ, in any convenient manner such as by injection, and cured if necessary, in the space between the skins 3, 4 and edge members 5, 6, 7 and bonds to these skins and edge members.
In this way the skins 3, 4 and edge members 5, 6, 7 are bonded together by the material 8 in a beam-like construction involving virtually no relative movement between the skins 3 and 4 to produce a strong panel section in which the material 8 makes a positive contribution to the panel section strength.
As the material 8 bonds the skins 3, 4 and edge members 5, 6, 7 together it is unnecessary to use any mechanical fasteners between the skins and edge members. Moreover, the use of plastics edge members 5, 6, 7, preferably made of polyvinylchloride, avoids any metallic connection between the skins 3 and 4 and thus avoids the formation of any thermal bridge therebetween.
Furthermore by using foamed insulating material 8, which preferably substantially fills the space between the skins 3, 4 and edge members 5, 6, 7, air spaces, which would otherwise allow condensation and absorption of water, are avoided. Moreover in view of the bonding of the material 8 to the skins 3, 4, these need not be made of rigid sheet material but can be made of any material, preferably sheet, to which the material 8 will bond. The skins 3, 4 may have flat surfaces to minimize dust collection and such a door may be fabricated without use of expensive roll forming equipment.
The hinges 2 interconnect horizontal edges of the panels sections 1 and are secured to the inner skins 3 of adjoining panel sections.
Conveniently the hinges are bolted to the skins 3 and to reinforcing stiles P, conveniently made of metal, located between the skins 3, 4 and bonded to the inner skin 3 by the material 8. The edge members are preferably extrusions channel shaped in cross section and may be shaped to provide a mounting for seal elements such as interpanel section seal elements 10 and a bottom seal element 11 on the edge members 6, and a brush seal element 12 on edge member 7 for sealing against door guide tracks 13. This brush seal element 12 preferably is made of silicone rubber and is attached by adhesive to at least one or each edge member 7. Alternatively, as shown in Fig. 3, at least one of the edge members 7 may be recessed to provide a channel in which a polypropylene brush seal element 12 may be inserted.
WHAT WE CLAIM IS:
1. An insulated sectional door having hingedly interconnected panel sections, wherein at least one panel section has an inner skin, a superimposed outer skin laterally spaced therefrom, plastics edge members closing spaces defined between spaced adjacent edges of the superimposed skins, and plastics insulating material foamed in situ in the space between the skins and edge members and bonded to the skins and edge members.

7. A door according to any one of claims 1 to 6, wherein the plastics edge members operatively forming the bottom member of at least one panel section is channel shaped in.
cross section and is shaped to provide a mounting for at least one seal element.
8. A door according to any one of Claims 1 to 7, wherein hinge reinforcing stiles are bonded between the skins.
9. A door according to any one of Claims 1 to 8, wherein at least one of the edge members is provided with a brush seal element.
10. A door according to Claim 9, wherein the brush seal element is attached by adhesive to at least one edge member.
