Abstract
Abstract A framing system for a building, house, storage cabinet, or the like employing a plurality of novel structural members or clip-in-joists and a plurality of other structural members, such as channels, I-beams, or the like. The clip-in-joists are special channel members or extrusion joists which have a slot or cut in each leg thereof opposite each other and near the end of the joist. The slotted end section of the joist is adapted to be inserted or snapped-in a second structural member, such as an I-beam or channel member or other structural member having a similar receiving configuration. The member is preferably made of structural aluminum, but can also be made from metals such as iron, steel and the like or plastics such as PVC, ABS, styrene and the like. A wide variety of structural materials may be used, depending upon the particular requirements of the end or resulting construction. Preferably, the framing system is so constructed that a flush structure is provided on which decking or sheathing may be easily attached or secured thereon.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
239 words
A framing system for a building or structure, comprising: a plurality of special structural connections; each of said special structural connections comprising, a special channel member and a special receiving structural member joined thereto; said special channel member having a pair of vertical legs extending substantially the length thereof and each joined to the base of the channel by an inclined corner wall, each of said channel member legs having leg portions formed on one end thereof by opposing cuts extending through said channel member vertical legs and said inclined walls, said cuts extending the height of said channel member vertical legs; said leg portions being bent toward each other; said special receiving structural member having a pair of legs extending substantially the length thereof, said structural member legs being spaced apart and having an opening therebetween, said opening being of a size sufficiently large for receiving said bent toward each other leg portions but sufficiently small for rejecting said channel member legs; said bendable leg portions of said special channel member being inserted in said opening between said legs of said special structural member in a tight frictional relationship without distortion in said structural receiving member; and, the external surfaces of said vertical legs of said special channel member being substantially flush with the external surfaces of said legs of said special structural receiving member, thereby providing a substantially flat surface for receiving a decking or sheathing member.
Claim 2
Dependent Claim
239 words
A framing system for a building or structure, comprising: a plurality of special structural connections; each of said special structural connections comprising, a special channel member and a special receiving structural member joined thereto; said special channel member having a pair of vertical legs extending substantially the length thereof and each joined to the base of the channel by an inclined corner wall, each of said channel member legs having leg portions formed on one end thereof by opposing cuts extending through said channel member vertical legs and said inclined walls, said cuts extending the height of said channel member vertical legs; said leg portions being bent toward each other; said special receiving structural member having a pair of legs extending substantially the length thereof, said structural member legs being spaced apart and having an opening therebetween, said opening being of a size sufficiently large for receiving said bent toward each other leg portions but sufficiently small for rejecting said channel member legs; said bendable leg portions of said special channel member being inserted in said opening between said legs of said special structural member in a tight frictional relationship without distortion in said structural receiving member; and, the external surfaces of said vertical legs of said special channel member being substantially flush with the external surfaces of said legs of said special structural receiving member, thereby providing a substantially flat surface for receiving a decking or sheathing member.
Claim 3
Dependent Claim
21 words
The framing system of claim 1 wherein said special channel members and said special structural members are made from structural aluminum.
Claim 4
Dependent Claim
16 words
The framing system of claim 1 wherein said special structural members comprise I-beams and channel members.
Claim 5
Dependent Claim
26 words
The framing system of claim 1 wherein said special channel members and said special structural members are made from iron, steel, galvanized steel or the like.
Claim 6
Dependent Claim
31 words
The framing system of claim 1 wherein said special channel members and said special structural members are made from plastic, ABS plastic, PVC plastic, styrene plastic, fiber glass or the like.
