Crown molding with improved mounting surfaces

Abstract

A crown molding unit for engagement with a ceiling surface and an adjacent wall surface of a room has a first surface positioned for flush contact with a ceiling surface and simultaneously, a second surface positioned for flush contact with a wall surface. Each of the first and the second surfaces provide a plurality of side-by-side parallel longitudinal grooves and a plurality of side-by-side parallel lateral grooves, the lateral grooves lie orthogonal to the longitudinal grooves and converge to a depression in the apparatus.

AI Technical Summary

Benefits of technology

[0023] A yet further objective is to provide such a molding that is able to retard shrinkage of the unit after installation.

Problems solved by technology

Our prior art search with abstracts described above teaches molding systems with longitudinal grooves, but fails to teach a lateral groove system used with the prior art longitudinal grooves.

However, the installation and durability of such crown moldings suffer from three deficiencies; first standard moldings, even those with longitudinal grooves do not have adequate groove structure for uniformly spreading bonding agents, as such agents need to be able to move laterally on the contact surface as well as longitudinally, second wall and ceiling surfaces often have rough textures and the use of longitudinal grooves only often results in the grooves sitting up on such textures so that added manicuring must be attended to in order to fill all gaps around the molding, and finally, it has been found that dual orthogonal grooves has the effect of retarding shrinkage of the molding, which is often a major cause for concern.
