US Patent 7198746 Method of connection with synthetic resin member

A method for connecting a member includes the steps of providing a member to be connected having a flange at an end to be connected with a bucklingly deformable synthetic resin member having an overhanging portion which overhangs the flange. A synthetic resin member is selected from the group a polystyrene, a styrene copolymer, an acrylic resin, a polycarbonate, a polyvinyl chloride, a polymethyl methacrylate, a polyamide, a polyacetal, a polyethylene terephthalate, a fluorocarbon resin and a thermoplastic polyurethane. The overhanging portion of the synthetic resin member is disposed over the flange of the member to be connected with the tip of the overhanging portion being bucklingly deformed toward the member to be connected to the extent that stress rupture does not occur. The flange is locked by the bucklingly deformed tip of the overhanging portion.
