Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 247 words
A structural joint assembly including a pair of elongate tubular structural members joined together in right angular relationship, comprising a first elongate tubular structural member of substantially rectangularly shaped cross-section and with opposite flat walls and opposite corners, said walls terminating at their longitudinal side edges short of said corners and including inset wall portions defining part of an outwardly opening, closed bottom channel means at the corners, a pair of opposite walls extending at their opposite side edges beyond said inset wall portions and overhanging a portion of said channel means and comprising an outer wall of said channel means flush with a respective one of said pair of walls, so that said channel means open outwardly parallel to the plane of a respective one of said pair of walls, a second elongate tubular structural member of substantially rectangular cross-section and with an open end, a substantially U-shaped fastening clip means with a pAir of spaced apart, resiliently yieldable legs frictionally engaged in said open end with a free end of each leg projecting out of said open end, said U-shaped fastening clip means each spanning a respective one of said pair of walls from one longitudinal edge to the other longitudinal edge thereof, an inturned flange on the free end of each leg and engaged in a respective channel means at opposite edges of one of said walls to releasably secure the second structural member to the first structural member in right angular relationship thereto.
Claim 2
Dependent Claim 247 words
A structural joint assembly including a pair of elongate tubular structural members joined together in right angular relationship, comprising a first elongate tubular structural member of substantially rectangularly shaped cross-section and with opposite flat walls and opposite corners, said walls terminating at their longitudinal side edges short of said corners and including inset wall portions defining part of an outwardly opening, closed bottom channel means at the corners, a pair of opposite walls extending at their opposite side edges beyond said inset wall portions and overhanging a portion of said channel means and comprising an outer wall of said channel means flush with a respective one of said pair of walls, so that said channel means open outwardly parallel to the plane of a respective one of said pair of walls, a second elongate tubular structural member of substantially rectangular cross-section and with an open end, a substantially U-shaped fastening clip means with a pAir of spaced apart, resiliently yieldable legs frictionally engaged in said open end with a free end of each leg projecting out of said open end, said U-shaped fastening clip means each spanning a respective one of said pair of walls from one longitudinal edge to the other longitudinal edge thereof, an inturned flange on the free end of each leg and engaged in a respective channel means at opposite edges of one of said walls to releasably secure the second structural member to the first structural member in right angular relationship thereto.
Claim 3
Dependent Claim 33 words
A structural joint assembly as in claim 1, wherein snap-locking means are on said fastening clip means and complementary snap-locking means are on said second structural member, said snap-locking means being cooperatively interengaged.
Claim 4
Dependent Claim 32 words
A snap-locking structural joint assembly as in claim 28, wherein said U-shaped fastening clip means includes a bight portion and said pair of legs extend from opposite sides of said bight portion.
Claim 5
Dependent Claim 27 words
