Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A connector for securing together two structural members comprising a first structural member having a C-shaped channel section with an inwardly directed flange on each side of, and in the plane of, the channel section opening, and a second structural member having a simple channel section consisting of a web joining two spaced side portions, comprising in combination, a sheet metal member having two end portions which lie in a common plane interconnected by a central portion which extends to one side of said common plane so as to define an aperture with said common plane, means for connecting said end portions which lie in a common plane to the inwardly directed flanges in the plane of the first structural member channel opening, said second structural member side portions each having an aperture formed therein for receiving a pin-like member whereby said side portion apertures will be aligned with the aperture defined by the sheet metal member upon juxtopositioning of the structural members together for securement together by the said pin-like member.
Claim 2
Dependent Claim
172 words
A connector for securing together two structural members comprising a first structural member having a C-shaped channel section with an inwardly directed flange on each side of, and in the plane of, the channel section opening, and a second structural member having a simple channel section consisting of a web joining two spaced side portions, comprising in combination, a sheet metal member having two end portions which lie in a common plane interconnected by a central portion which extends to one side of said common plane so as to define an aperture with said common plane, means for connecting said end portions which lie in a common plane to the inwardly directed flanges in the plane of the first structural member channel opening, said second structural member side portions each having an aperture formed therein for receiving a pin-like member whereby said side portion apertures will be aligned with the aperture defined by the sheet metal member upon juxtopositioning of the structural members together for securement together by the said pin-like member.
Claim 3
Dependent Claim
66 words
A connector as claimed in claim 1 in which the means for connecting the end portions to the first structural member consists of each end portion of the sheet metal member having laterally extending portions on both sides thereof which can be located within the channel section of the first structural member so as to engage behind the inwardly directed flanges of the said structural member.
Claim 4
Dependent Claim
59 words
A combination as claimed in claim 2 in which the laterally extending portions of each end portion are joggled with respect to an intermediate portion so that the intermediate portion is received within the opening of the channel section structural member and lies closely adjacent the inner edges of the inwardly directed flanges on each side of the opening.
Claim 5
Dependent Claim
29 words
A combination as claimed in claim 3 in which the sheet metal portion is connected to the said one structural member by being welded thereto by said end portions.
Claim 6
Dependent Claim
33 words
A combination as claimed in claim 4 in which each end portion is welded to said one structural member along the adjacent edges of the intermediate portion and of the inwardly directed flanges.
Claim 7
Dependent Claim
40 words
A combination as claimed in claim 3 in which, when the structural members are connected together, the two side portions of the second structural member are positioned closely adjacent each side of the central portion of the sheet metal member.
Claim 8
Dependent Claim
46 words
A combination as claimed in claim 6 in which the web of the channel section of the second structural member between said apertured side portions is shaped so that it engages the central portion of the sheet metal member when the structural members are connected together.
Claim 9
Dependent Claim
81 words
A combination as claimed in claim 7 in which the structural members are adapted to be assembled together with said first structural member extending substantially vertically and said second structural member extending substantially horizontally with the web uppermost, and in which the web between the apertured side portions is inclined upwards relative to the rest of the web so as to lie on a surface of the central portion of the sheet metal member when the structural members are connected together.
Claim 10
Dependent Claim
68 words
A combination as claimed in claim 6 in which the ends of the apertured side portions of the channel section second structural member are outwardly bent to form flanges adapted to engage the inwardly directed flanges of the first structural member so as to bear against the latter and hold the said first structural member against rotation about the pin-like member when the structural members are connected together.
Claim 11
Dependent Claim
36 words
A combination as claimed in claim 9 in which the central portion of the sheet metal member is V-shaped and the pin-like member engages the angle of the V when the structural members are connected together.
Claim 12
Dependent Claim
30 words
A combination as claimed in claim 9 in which the pin-like member is a bolt and in which a nut is threaded on the bolt to hold it in place.
