Abstract
Abstract In a disclosed panel frame system at least one sill assembly is supported by an elongated base member, with a pair of vertically extending mullion or jamb assemblies disposed on the base member at opposite ends of the sill assembly, and with an elongated head channel assembly secured to the ceiling in alignment with the base member. The sill, mullion, and head channel assemblies each include a removable plate which may be snapped into rigid mating relationship with the sill, mullion, or head channel members. The inwardly facing surfaces of the sill, mullion and head channel plates may be provided with a panel receiving recess. The lower extremity of a mullion member broad wall defines a pair of notches which snugly receive flanged sidewalls of the base member. A single base rail embodiment and a ledge sill embodiment of the frame system are also disclosed.

Claim 1
Independent Claim
422 words
A panel frame assembly comprising: an elongated base member having a bottom wall and a pair of parallel sidewalls, said bottom wall defining a pair of ledge portions respectively extending beyond said sidewalls, at least one of said sidewalls defining near its upper extremity an inwardly projecting longitudinal flange portion having a flat surface disposed parallel to said sidewalls; at least one sill member having a pair of sidewalls disposed parallel to and outwardly of said sidewalls of said base member, each of said sidewalls of said sill member defining at its lower extremity at least one inwardly projecting portion resting on the adjacent one of said base member ledge portions and the inner edge of which is disposed adjacent one of said base member sidewalls; first and second vertical frame members disposed on said base member at opposite ends of said sill member, each said vertical frame member having a first broad wall of a width greater than the distance between said sidewalls of said base member and disposed perpendicular to said sidewalls of said base member, a pair of sidewalls, and a pair of broad wall portions spaced from said first broad wall and extending inwardly from the respective vertical frame member sidewalls into contact with the outer surfaces of the respective base member sidewalls, said first broad wall defining adjacent its bottom end a pair of notches having their respective outer edges contacting the respective outer surfaces of said base member sidewalls and each notch being dimensioned to snugly receive said one of said base member sidewalls and its flange portion, an elongated plate adapted to contact the inner extremities of said broad wall portions of each said vertical frame member in engaging relationship therewith, the lower edge of said plate being adapted to rest on the upper extremity of said one of said base member sidewalls; an elongated head channel member adapted to be affixed to a ceiling surface in substantial alignment with said base member, said head channel member defining a top wall and a pair of sidewalls disposed parallel to said sidewalls of said base member, said head channel member sidewalls being spaced from one another by a distance slightly greater than the width of said vertical frame member first broad wall and each being adapted to contact the outer surface of one of said sidewalls of each said vertical frame member, an elongated head channel plate adapted to contact said head channel member in engaging relationship therewith at a location opposite to said top wall.
Claim 2
Dependent Claim
422 words
A panel frame assembly comprising: an elongated base member having a bottom wall and a pair of parallel sidewalls, said bottom wall defining a pair of ledge portions respectively extending beyond said sidewalls, at least one of said sidewalls defining near its upper extremity an inwardly projecting longitudinal flange portion having a flat surface disposed parallel to said sidewalls; at least one sill member having a pair of sidewalls disposed parallel to and outwardly of said sidewalls of said base member, each of said sidewalls of said sill member defining at its lower extremity at least one inwardly projecting portion resting on the adjacent one of said base member ledge portions and the inner edge of which is disposed adjacent one of said base member sidewalls; first and second vertical frame members disposed on said base member at opposite ends of said sill member, each said vertical frame member having a first broad wall of a width greater than the distance between said sidewalls of said base member and disposed perpendicular to said sidewalls of said base member, a pair of sidewalls, and a pair of broad wall portions spaced from said first broad wall and extending inwardly from the respective vertical frame member sidewalls into contact with the outer surfaces of the respective base member sidewalls, said first broad wall defining adjacent its bottom end a pair of notches having their respective outer edges contacting the respective outer surfaces of said base member sidewalls and each notch being dimensioned to snugly receive said one of said base member sidewalls and its flange portion, an elongated plate adapted to contact the inner extremities of said broad wall portions of each said vertical frame member in engaging relationship therewith, the lower edge of said plate being adapted to rest on the upper extremity of said one of said base member sidewalls; an elongated head channel member adapted to be affixed to a ceiling surface in substantial alignment with said base member, said head channel member defining a top wall and a pair of sidewalls disposed parallel to said sidewalls of said base member, said head channel member sidewalls being spaced from one another by a distance slightly greater than the width of said vertical frame member first broad wall and each being adapted to contact the outer surface of one of said sidewalls of each said vertical frame member, an elongated head channel plate adapted to contact said head channel member in engaging relationship therewith at a location opposite to said top wall.
Claim 3
Dependent Claim
92 words
A panel frame assembly according to claim 1 and further including a removable sill member adapted to contact said sill member in engaging relationship therewith, said removable sill member and the upper portion of said sill member together defining a panel receiving recess; and wherein said head channel plate and at least one of said vertical frame member first broad wall and the said elongated plate in engaging relationship with the inner extremities of said broad wall portions of said vertical frame member defines a panel receiving recess on its outer surface.
Claim 4
Dependent Claim
32 words
A panel frame assembly according to claim 1 wherein said inwardly projecting longitudinal flange portion of said one of said sidewalls of said elongated base member has an essentially C-shaped cross section.
Claim 5
Dependent Claim
50 words
A panel frame assembly according to claim 1 wherein said vertical frame member first broad wall defines a panel receiving recess having a pair of parallel sidewalls, at least one of which is disposed at a location adjacent said longitudinal flange portion of said one of said base member sidewalls.
Claim 6
Dependent Claim
58 words
A panel frame assembly according to claim 1 wherein each of said sidewalls of said sill member defines a plurality of inwardly projecting longitudinal ridge portions having flat surfaces contacting the adjacent one of said base member sidewalls, the bottom ridge portion of each sill member sidewall resting on the adjacent one of said base member ledge portions.
Claim 7
Dependent Claim
40 words
A panel frame assembly according to claim 5 wherein each of said sidewalls of said elongated base member defines near its upper extremity an inwardly projecting longitudinal flange portion having a flat surface disposed parallel to said base member sidewalls.
Claim 8
Dependent Claim
89 words
A panel frame assembly according to claim 1 wherein said sill member has a pair of bottom wall portions extending inwardly from the lower extremities of the respective sill member sidewalls to a preselected distance such that the spacing between the respective inner extremities of said bottom wall portions is slightly less than the width of said base member bottom wall, said sill member bottom wall portions each defining an inwardly and upwardly projecting flange portion adapted to rest on the adjacent one of said base member ledge portions.
