Abstract
Abstract Building components are disclosed for constructing of frames, enclosures, and the like, comprising hollow edge struts all of uniform cross section, with the ends of each edge strut providing a female joint. Interlocking members are provided having a central member with a plurality of legs extending outwardly from the central member and at fixed angles to each other, the legs each defining a male member adapted to be inserted in said female joint. The legs have locking clip recesses formed therein in at least two adjacent surfaces of the legs, the locking clip recesses spanning substantially the entire width and length of the surfaces of the legs. An abuttment shoulder is formed at the central member and end of the locking clip recess which the edge strut butts up against when installed. Locking clips are provided having arms corresponding in number, and disposed within the locking clip recesses formed in the legs are inserted within the locking clip recesses before the edge struts are interlocked with the legs. The arms on each of the locking clips have a plurality of upstanding locking tabs formed therein to increase the strength of joints. The edge struts are cut to a specific length and interlock together by means of the interlocking members to form frames, enclosures, and the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
192 words
Building components for constructing frames, enclosures and the like comprising, hollow edge struts all of uniform cross-section, the ends of each said strut providing a female joint, interlocking members having a central member with a plurality of legs extending outwardly therefrom and at fixed angles to each other, said legs each defining a male member adapted to be inserted in said female joints and having locking clip recesses formed therein in at least two adjacent surfaces of predetermined ones of said legs, said locking clip recesses spanning substantially the entire width of said surfaces of said legs and substantially the entire length thereof so as to form an abutment shoulder adjacent the ends thereof and the central member, a locking clip having arms corresponding in number to and disposed within said locking clip recesses formed in said legs, said arms each having a plurality of upstanding locking tabs formed therein and having a length and a width co-extensive with those of said locking clip recesses, said edge struts each being cut to a specific length and interlocked together by means of said interlocking members to form said frames, enclosures and the like.
Claim 2
Dependent Claim
192 words
Building components for constructing frames, enclosures and the like comprising, hollow edge struts all of uniform cross-section, the ends of each said strut providing a female joint, interlocking members having a central member with a plurality of legs extending outwardly therefrom and at fixed angles to each other, said legs each defining a male member adapted to be inserted in said female joints and having locking clip recesses formed therein in at least two adjacent surfaces of predetermined ones of said legs, said locking clip recesses spanning substantially the entire width of said surfaces of said legs and substantially the entire length thereof so as to form an abutment shoulder adjacent the ends thereof and the central member, a locking clip having arms corresponding in number to and disposed within said locking clip recesses formed in said legs, said arms each having a plurality of upstanding locking tabs formed therein and having a length and a width co-extensive with those of said locking clip recesses, said edge struts each being cut to a specific length and interlocked together by means of said interlocking members to form said frames, enclosures and the like.
Claim 3
Dependent Claim
44 words
Building components, as claimed in claim 1, wherein, said interlocking members have locking clip recesses formed therein in two adjacent surfaces of predetermined ones of said legs, and wherein said locking clips are L-shaped having two arms disposed at right angles to one another.
Claim 4
Dependent Claim
37 words
Building components, as claimed in claim 2, wherein, at least one leg of said interlocking members has a locking clip recess formed in three adjacent surfaces thereof, and wherein said locking clip is U-shaped having three arms.
Claim 5
Dependent Claim
74 words
Building components, as claimed in claim 1, wherein at least one of said legs of said interlocking members has a leg cavity extending longitudinally through it from its end and the other legs thereof have a recessed cavity formed in their surfaces which face in a direction opposite to the direction of said leg cavity, whereby a lighter-weight interlocking member is provided and said interlocking members can be formed in molds using unidirectional coring.
Claim 6
Dependent Claim
27 words
Building components, as claimed in claim 4, wherein said leg having said leg cavity formed in it has rib means formed on at least one surface thereof.
Claim 7
Dependent Claim
54 words
Building components, as claimed in claim 1, wherein said locking clips are of a substantially sturdy, resilient material and said upstanding locking tabs are partially severed and are folded to extend angularly upwardly so as to frictionally engage the interior surface of said edge struts when the latter are assembled with said interlocking members.
Claim 8
Dependent Claim
191 words
An interlocking member for use with hollow edge struts of uniform cross-section and having ends providing a female joint to construct frames, enclosures and the like, said interlocking members comprising, a central member with a plurality of legs extending outwardly therefrom and at fixed angles to each other, said legs each defining a male member adapted to be inserted in said female joints and having locking clip recesses formed therein in at least two adjacent surfaces of predetermined ones of said legs, said locking clip recesses spanning the entire width of said surfaces of said legs and substantially the entire length thereof so as to form an abutment shoulder adjacent the ends thereof and the central member, a locking clip having arms corresponding in number to and disposed within said locking clip recesses formed in said legs, said arms each having a plurality of upstanding locking tabs formed therein and having a length and a width co-extensive with those of said locking clip recesses, said edge struts each being cut to a specific length and interlocked together by means of said interlocking members to form said frames, enclosures and the like.
Claim 9
Dependent Claim
191 words
An interlocking member for use with hollow edge struts of uniform cross-section and having ends providing a female joint to construct frames, enclosures and the like, said interlocking members comprising, a central member with a plurality of legs extending outwardly therefrom and at fixed angles to each other, said legs each defining a male member adapted to be inserted in said female joints and having locking clip recesses formed therein in at least two adjacent surfaces of predetermined ones of said legs, said locking clip recesses spanning the entire width of said surfaces of said legs and substantially the entire length thereof so as to form an abutment shoulder adjacent the ends thereof and the central member, a locking clip having arms corresponding in number to and disposed within said locking clip recesses formed in said legs, said arms each having a plurality of upstanding locking tabs formed therein and having a length and a width co-extensive with those of said locking clip recesses, said edge struts each being cut to a specific length and interlocked together by means of said interlocking members to form said frames, enclosures and the like.
