Abstract
An extruded plastic head rail for a blind of the type having blind elements suspended from such head rail, in which the head rail is reinforced to prevent sagging of the head rail under the load of the blind elements, and in which the head rail is suitable for trimming to length by a point of sale trim cutting apparatus, the head rail having a head rail extrusion extruded from plastic material and, a reinforcement member in the head rail, the reinforcement member extending along at least a median portion of length of the head rail, the reinforcement member supporting the head rail and the blind elements, to prevent bending of the head rail under the load of the blind elements.

An extruded plastic 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 an in store point of sale trim cutting apparatus, said head rail comprising:
- (a) a head rail extrusion extruded from plastic material for forming said head rail and defining at least a front wall and a bottom wall, said head rail being of a predetermined length;
- and
- (b) a reinforcement member in said head rail, said reinforcement member being the same length as said head rail, wherein said reinforcement member is formed of a material adapted to be cut by the in store point of sale trim cutting apparatus, said reinforcement member being adapted to support said head rail and said plurality of blind elements, and to prevent bending of said head rail under the load of said plurality of blind elements.
An extruded plastic 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 a point of sale trim cutting apparatus, said head rail comprising:
- (a) a head rail extrusion extruded from plastic material for forming said head rail and defining at least a front wall, a side wall and a bottom wall;
- (b) a reinforcement member in said head rail, said reinforcement member extending along at least a median portion of said head rail, said reinforcement member being adapted to support said head rail and said plurality of blind elements and to prevent bending of said head rail under the load of said plurality of blind elements, said reinforcement member having at least one planar strip of metallic material;
- (c) said head rail being formed with at least one partition wall along said side wall, defining at least one elongated passage therein;
- and
- wherein at least one metallic strip being received within said at least one passage.
An extruded plastic 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 a point of sale trim cutting apparatus, said head rail comprising:
- (a) a head rail extrusion extruded from plastic material for forming said head rail and defining at least a front wall and a bottom wall;
- (b) a reinforcement member in said head rail, said reinforcement member extending along at least a median portion of said head rail, said reinforcement member being adapted to support said head rail and said plurality of blind elements, and to prevent bending of said head rail under the load of said plurality of blind elements;
- and
- (c) said reinforcement member having a plurality of reinforcement rods embedded in said head rail.
An extruded plastic 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 a reduced length at a point of sale establishment by a trim apparatus, said head rail comprising:
- (a) a head rail extrusion extruded from plastic material for forming said head rail and defining at least one side wall and a bottom wall, said head rail having two ends spaced at a predetermined length;
- (b) said head rail being formed with at least one partition wall along at least one said side wall defining at least one elongated passage therein;
- (c) a reinforcement member in said head rail having at least one planar strip of metallic material, wherein said strip is received within said at least one passage of said head rail;
- (d) said reinforcement member being of a length shorter than said predetermined length of said head rail and extending along a median portion of said head rail and terminating short of said ends of said head rail;
- and
- (e) plug members located in each end of said head rail in which said reinforcement member is absent, wherein said plug members are formed of a material softer than said reinforcement member, whereby said head rail may be cut at each end in the region of said plug members.
An extruded plastic 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 a reduced length at a point of sale establishment by a trim cutting apparatus, said head rail comprising:
- (a) a head rail extrusion extruded from plastic material for forming said head rail and defining at least a front wall, a bottom wall, and two ends separated by a predetermined length;
- (b) a reinforcement member of a material stiffer than said head rail and located in said head rail, said reinforcement member being the same length as said head rail and extending from end to end of said head rail, for supporting said head rail and said plurality of blind elements, and to prevent bending of said head rail under the load of said plurality of blind elements;
- and
- (c) said reinforcement member being formed of a material having characteristics adapting it to be trimmed by the trim cutting apparatus.
