  • Borderwire hinge clip
    Patent number: 4790519
    Abstract: A clip for use in a hinged border wire assembly, such as a border wire assembly used in a mattress, joins border wire portions together in a manner that permits one border wire section to rotate with respect to the other. This permits folding of a large border wire of the type that would be used on a king-size mattress, for example, in order to pass the mattress through small areas such as doors and stairways. The disclosed embodiment has two border wire sections which are generally U-shaped and which abut along portions formed at the ends of each U. The clip has a pair of adjacent sleeves within which respective abutting border wire portions are received. A barb is formed inwardly of a sleeve to secure the barbed sleeve in place on its border wire portion while allowing the other abutting portion to rotate within its sleeve in hinged fashion.
