Architectural trim
View Patent ↗An improved architectural trim device constructed from cellular polyvinylchloride. The process employs manufacturing dimensionalized cellular PVC architectural components from a single sheet of plastic that can achieve both linear and radius shapes without using heat bending techniques. The process strengthens the cellular PVC, giving it more structural integrity than other products made strictly of cellular PVC. These techniques enable the manufacture of components with tighter tolerances than traditional heat bending techniques which distort the size and shape of the material making accurate and precise assembly difficult.
1. An architectural trim fabricated from a single piece of material, said trim comprising:
a front member having an inner surface and an outer surface with a thickness therebetween, said front member further defined by a rectangular shaped rigid base section coupled to a rectangular shaped curvature section by a first living hinge, said curvature section formed from a plurality of ridge shaped machine cuts placed parallel to each other allowing said curvature section to bend;
a left side member having a first rigid base coupled to a first edge of said rigid base of said front member by a second living hinge, said left side member including a first curved end extending from said first rigid base to a left side distal tip, said first curved section including a first beveled surface for receiving a first edge of said front member curvature section;
a right side member having a second rigid base coupled to a second edge of said rigid base of said front member by a third living hinge, said right side member including a second curved section extending from said first rigid base to a right side distal tip, said second curved section including a second beveled surface for receiving a second edge of said front member curvature section;
wherein said plurality of ridge shaped machine cuts permits said curvature section of said front member to bend conjugate to and interface with said left side member and said right side member, said members held in position with adhesive.
2. The architectural trim according to claim 1 wherein said material is cellular PVC.
3. The architectural trim according to claim 1 wherein said material is a wood-plastic composite.
4. The architectural trim according to claim 1 wherein said front member includes at least one reverse cut positioned along the inner surface providing a step along the outer surface.
5. The architectural trim according to claim 1 wherein said first edge of said rigid base is beveled and adjoined to said first edge of said left member, whereby said beveled edges form a ninety degree angle when juxtapositioned.
6. The architectural trim according to claim 1 wherein said second edge of said rigid base is beveled and adjoined to said second edge of said right member, whereby said beveled edges form a ninety degree angle when juxtapositioned.
7. The architectural trim according to claim 1 wherein said inner surface of said front member is attached to a mechanical fastener secured to a soffit of a building.
