Abstract
Abstract A prefabricated unitary body forming an archway is made of a light, durable material. The body includes a corner bead and abuts against the walls around the archway. The archway is nailed in place and drywall compound is applied, tapering from the corner bead of the archway to fill and cover the seam joining the archway within a framed opening of a doorway or window.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
141 words
A prefabricated archway attached to a framed opening, said prefabricated archway comprising: a single body including a curved section being concavely curved and having a planar face, an exterior surface of a side wall being located adjacent to a longitudinal edge of said planar face, an outer periphery of said side wall being shaped complementary to said framed opening and spacing said planar face from said framed opening when said single body is attached within said framed opening, cohesive means secured to said planar face and to said exterior surface of said side wall for defining an adhesion surface on said planar face and said side wall, and a width of said planar face attached within said framed opening aligns exterior surfaces of said framed opening continuous with the exterior surface of said side wall and continuous with said planar face.
Claim 2
Dependent Claim
141 words
A prefabricated archway attached to a framed opening, said prefabricated archway comprising: a single body including a curved section being concavely curved and having a planar face, an exterior surface of a side wall being located adjacent to a longitudinal edge of said planar face, an outer periphery of said side wall being shaped complementary to said framed opening and spacing said planar face from said framed opening when said single body is attached within said framed opening, cohesive means secured to said planar face and to said exterior surface of said side wall for defining an adhesion surface on said planar face and said side wall, and a width of said planar face attached within said framed opening aligns exterior surfaces of said framed opening continuous with the exterior surface of said side wall and continuous with said planar face.
