Benefits of technology

The present invention provides a fire rated door core that meets fire certification requirements. The core is made of a fire resistant center panel and an extruded fire resistant border. The fire resistant center panel is made of a first fire resistant material, while the extruded fire resistant border is made of a second fire resistant material with higher density. The extruded fire resistant border is attached to the center panel using a stile and rails. The core has a bottom, top, sides, ends, and a central void that is filled with a first fire resistant material. The extruded fire resistant border is made of a second fire resistant material. The technical effects of this invention include improved fire resistance and a simplified manufacturing process.

Problems solved by technology

But most of these prior art designs do not lend themselves well to fully automated manufacturing processes.
Moreover, the prior art fire rated doors are expensive and require the internal mineral core.
The internal core can be exposed in routed details and may reduce the strength of the door as a result of the reduced thickness of the door panels.
In addition, alignment of the panels during assembly can be troublesome and require additional finishing to square the door after assembly.

Abstract

A core for a fire rated door includes a fire resistant center panel and an extruded fire resistant border. The fire resistant center panel has a bottom, a top, a first side, a second side, a first end and a second end. The fire resistant center panel is made of a first fire resistant material. The extruded fire resistant border is attached to the first side, the second side, the first end and the second end of the fire resistant center panel. The extruded fire resistant border is made of a second fire resistant material having a higher density than the first fire resistant material.

Description

PRIORITY CLAIM AND CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This patent application is related to U.S. patent application Ser. No. ______ filed on Jun. 29, 2012 and entitled “Fire Rated Door”, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to the field of door manufacturing and, more particularly, to a fire rated door core.BACKGROUND OF THE INVENTION[0003]Many methods and techniques for manufacturing fire rated doors have been developed over time. But most of these prior art designs do not lend themselves well to fully automated manufacturing processes. Moreover, the prior art fire rated doors are expensive and require the internal mineral core. The internal core can be exposed in routed details and may reduce the strength of the door as a result of the reduced thickness of the door panels. In addition, alignment of the panels during assembly can be troublesome and require additional finishing to squa...
