Abstract
This invention relates to doors having internal blocking components that reduce or eliminate telegraphing of the outer surface of the door facings. In particular, the invention relates to steel-edge steel doors that have internal solid wood blocks that have one or more integral cantilever beams formed into the blocks to interact with the adjoined oppositely arranged door facings in order to eliminate visually apparent door telegraphing. The blocks are modified to contain notches formed therein to form the cantilever beams.
Claims19
A method for making a steel-edge door, the method comprising the steps of:
- providing a horizontally extending top rail;
- providing a horizontally extending bottom rail spaced from and parallel to the top rail;
- positioning first and second door facings on opposing sides of the rails, each of the door facing having a steel edge extending perpendicularly to the rails;
- and
- positioning a stile block adjacent to the edge intermediate the top and bottom rails, wherein the stile block has
- a top surface facing the top rail,
- a bottom surface opposing the top surface and facing the bottom rail,
- at least two first parallel notches, each of the at least two first parallel notches is formed in the top surface, extends away from the top rail, and terminates remote from the bottom surface, and
- at least two second parallel notches, each of the second parallel notches formed in the bottom surface, extends away from the bottom rail, and terminates remote from the top surface.
