Abstract
Abstract This invention provides an assembly for component parts which can be easily assembled to form a rigid structure such as the frame of an article of furniture, for example a table. The structure is made up of pairs of interengaging elongate elements, one element of each pair having a channel section and the other having a forked end which fits over the channel section to form a T-unit. The channel section element is formed, preferably by stamping, with an internal abutment for the head of a bolt which passes through the intersection of the elements and holds the latter together.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
An assembly of component parts adapted to be assembled to form furniture such as tables, shelving and the like, said assembly comprising at least one first and second elongate elements adapted to fit together, the first element having a channel section with divergent side walls and the second element having a forked end, the internal profile of said forked end being complementary to the external cross-sectional profile of the first element and a tie member adapted to hold said elements tightly interengaged upon assembly thereof, said first element being of sheet metal and including a cut out portion in each side wall which are deformed inwardly with respect to said side walls so that the edges of said cut out portions define an internal abutment within said first element which constitutes a reaction support for one end of said tie member.
Claim 2
Dependent Claim
141 words
An assembly of component parts adapted to be assembled to form furniture such as tables, shelving and the like, said assembly comprising at least one first and second elongate elements adapted to fit together, the first element having a channel section with divergent side walls and the second element having a forked end, the internal profile of said forked end being complementary to the external cross-sectional profile of the first element and a tie member adapted to hold said elements tightly interengaged upon assembly thereof, said first element being of sheet metal and including a cut out portion in each side wall which are deformed inwardly with respect to said side walls so that the edges of said cut out portions define an internal abutment within said first element which constitutes a reaction support for one end of said tie member.
Claim 3
Dependent Claim
58 words
An assembly as set forth in claim 1 further comprising two channel-section strips having flat substantially parallel side walls, said channel-section strips being fitted over and welded to opposite sides of said first member with the opposed ends of said strips being spaced apart to define shoulders which engage and locate the forked end of said second element.
Claim 4
Dependent Claim
154 words
An assembly of component parts adapted to be assembled to form furniture such as tables, shelving and the like, said assembly comprising at least one first and second elongate elements adapted to fit together, the first element having a channel section with divergent side walls and the second element having a forked end, the internal profile of said forked end being complementary to the external cross-sectional profile of the first element, a tie member adapted to hold said elements tightly interengaged upon assembly thereof, and an internal abutment provided in said first element which constitutes a reaction support for one end of said tie member and two channel-section strips having flat substantially parallel side walls, said channel-section strips being fitted over and welded to opposite ends of said first member with the opposed end of said strips being spaced apart to define shoulders which engage and locate the forked end of said second element.
Claim 5
Dependent Claim
154 words
