Blind with reinforced head rail

An extruded head rail for a blind having a plurality of blind elements suspended from a head rail, said head rail being reinforced to prevent sagging of said head rail under the load of said plurality of blind elements, and being suitable for trimming to length by cutting apparatus, said head rail comprising:

• (a) a head rail extrusion extending along a length to present two opposite ends;
• (b) a reinforcement member in said head rail, said reinforcement member capable of being trimmed by said cutting means;
• (c) a plug member slidingly disposed in each end of said head rail to overlap with said reinforcement member and lock said reinforcement member between said plug member and said head rail to inhibit movement of said reinforcement member when said head rail, reinforcement member and plug members are subjected to cutting.

A plug for an extruded head rail for a blind having a plurality of blind elements suspended from a head rail, said head rail extruded along a length thereof to present two opposite ends, said head rail having a substantially channel-shaped cross-section with a head rail bottom wall, and two spaced head rail upstanding sidewalls, each terminating at an upper edge, said plug disposed for slidable movement in one end of said head rail, said plug including projection means for engaging each said upper edge of said head rail sidewalls to inhibit movement of said sidewalls when trimming said length of of said head rail.
