Among his latest inventions is the "Self-expanding blind fastener with mechanical lock." This innovative fastener is designed for clamping sheet components and features a mechanical lock that prevents loosening. The fastener expands automatically after insertion and engagement of the threaded stem. It consists of an internally threaded nut body, an externally threaded stem, and a lock sleeve that securely holds the nut body. The expandable sleeve engages the underside of the material, ensuring a tight fit. The rotation of the stem draws the head and sleeve against the material, causing the sleeve to expand outwardly. The locking sleeve is positioned beneath the expansion sleeve, creating a mechanical lock that resists vibration and secures the fastener.
Another significant patent is the "Blind fastener with deformable sleeve." This fastener includes a body, a core bolt, a nut, and a sleeve. The core bolt passes through the body and features an externally threaded portion. The nut has an enlarged head and a reduced diameter stem, which engages the threaded portion of the core bolt. The sleeve is positioned between the nut's head and the conically shaped inner portion of the body. The inner end of the sleeve is fixed to the nut's stem, ensuring a robust connection during the fastening process.
