Patent number: 6345747Abstract: In a strap assembly for carrying a portable device, in order to protect a user against the action of an unexpected sudden external force, a cord for installing the strap assembly to the portable device is passed through an installation hole of a coupling from the inside such that a knot of a strap is supported by the rim of the installation hole. Coupling holes in both ends of the strap hung from the body of the user are fitted over support posts formed on the inner bases of first and second coupling members. Tapered surfaces are formed on portions of the cylindrical side surfaces of support posts. When the first and second coupling members are closed together with their rims superposed, protrusions of one member engage recesses of another coupling member. If a tension load in excess of a given level is applied to the portable device, a reactive force from the strap acts upon the tapered surfaces, resulting in force components that release the engaged state of these protrusions and recesses.Type: GrantFiled: November 5, 1999Date of Patent: February 12, 2002Assignee: Sony Computer Entertainment, Inc.Inventors: Hiroki Ogata, Yasuhiro Ootori
