Window assembly and fitting therefor

A window frame member comprising:

• a unitary molded half-frame having first, second, third and fourth portions;
• said first and second portions defining spaced-apart top and bottom transverse members of said half-frame;
• said third and fourth portions defining spaced apart left hand and right hand upright members of said half-frame;
• said first, second, third and fourth portions co-operating to form a four-sided surround of an opening in which to mount glazing;
• said half-frame having a forwardly facing fascia, a first rearwardly extending wall terminating in a flange spaced rearwardly from said fascia defining a rearwardly facing land operable to engage the glazing;
• each half-frame having a peripheral second wall located laterally outboard of said first rearwardly extending wall and spaced therefrom, said second wall extending rearwardly from said fascia and defining a stem wall relative thereto;
• an array of securement fittings rooted to said fascia and spaced about said stem wall;
• said array of securement fittings including a set of male securement fittings and a set of female securement fittings, said male securement fittings and said female securement fittings being equal in number and having corresponding mating serrated one-direction engagement serrated profiles;
• said female securement fittings fittings each including a pair of legs abutting said stem wall and co-operating therewith to form a C-shaped section;
• there being a parting line where an inboard edge of said legs of the female securement fittings meet said stem wall;
• said male securement fittings abutting, and merging into, said stem wall, there being a parting line where said male securement fittings meet said stem wall;
• there being an array of plates mounted to said stem wall and co-operating with legs of ones of said female securement fittings to form channel sections, said plates defining insert range of travel limit stops;
• said half-frame having a first direction of formation normal to said opening of said surround;
• said half-frame having at least a second direction of formation on which respective ones of said securement fitting are formed on said first portion of said half-frame, and a third direction of formation on which respective others of said securement fittings are formed on said third portion of said half-frame;
• and
• said fascia of said half-frame being free of mechanical fastener penetrations.

A window frame member comprising:

• a one-piece molding defining first and second spaced apart transverse members and first and second upright members, said upright members and said transverse members co-operating to form a first four-sided half-frame;
• said four-sided half-frame having an outside having an external facing, and an inside;
• said inside having an array of molded securement fittings, said molded securement fittings being operable, on installation, to engage corresponding mating fittings of another co-operating half-frame;
• said first half-frame having a first direction of formation normal to said external facing;
• at least a first of said plurality of molded securement fittings of said first half-frame having at least a second direction of formation;
• said second direction of formation being skewed relative to said first direction of formation;
• said second direction of formation being at least predominantly transverse to said first direction of formation;
• said window frame member includes a fascia defined by said external facing, a peripheral wall extending rearwardly of said fascia, and a rearwardly depending land connected to an inboard margin of said fascia, said rearwardly depending land being spaced from said peripheral wall;
• at least a first female securement fitting abuts said peripheral wall, said first female securement fitting includes first and second spaced-apart legs that stand rearwardly of said fascia and that co-operate with said peripheral wall to form a C-shaped channel section therewith;
• said window frame member includes at least a first plate that co-operates with said first and second legs of said first female securement fitting to form a C-shaped section, said plate is rooted to said peripheral wall, and said plate extends lengthwise beyond said legs of said first female securement fitting, said plate having a distal tip defining an engagement range of travel limit abutment.

A window frame member comprising:

• a unitary molded half-frame having first, second, third and fourth portions;
• said first and second portions defining spaced-apart top and bottom transverse members of said half-frame;
• said third and fourth portions defining spaced apart left hand and right hand upright members of said half-frame;
• said first, second, third and fourth portions co-operating to form a four-sided surround of an opening in which to mount glazing;
• said half-frame having a forwardly facing fascia, a first rearwardly extending wall terminating in a flange spaced rearwardly from said fascia defining a rearwardly facing land operable to engage the glazing;
• each half-frame having a peripheral second wall located laterally outboard of said first rearwardly extending wall and spaced therefrom, said second wall extending rearwardly from said fascia and defining a stem wall relative thereto;
• an array of securement fittings rooted to said fascia and spaced about said stem wall;
• said array of securement fittings including a set of male securement fittings and a set of female securement fittings, said male securement fittings and said female securement fittings being equal in number and having corresponding mating serrated one-direction engagement serrated profiles;
• said female securement fittings fittings each including a pair of legs abutting said stem wall;
• said male securement fittings abutting said stem wall;
• there being an array of plates mounted to said stem wall and co-operating with respective legs of ones of said female securement fittings to form channel sections, said plates defining insert range of travel limit stops;
• and
• said fascia of said half-frame being free of mechanical fastener penetrations.
