Title: Paul P Krawiec: Innovator in Fastener Technology
Introduction
Paul P Krawiec is a notable inventor based in Hacienda Heights, California. He has made significant contributions to the field of fastener technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
Krawiec's latest patents include a self-expanding blind fastener with a mechanical lock. This innovative fastener is designed for clamping sheet components and features a mechanical lock that prevents loosening. The fastener expands following insertion and engagement of the threaded stem, ensuring a secure fit. It consists of an internally threaded nut body, an externally threaded stem, and a lock sleeve that mates with the nut body. An expandable sleeve is carried on the stem, which expands to engage the underside of the material. The rotation of the stem after insertion draws the stem head and expandable sleeve against the backside of the material, causing the sleeve to expand outwardly. The locking sleeve is pushed beneath the expansion sleeve, wedging between the threaded stem and expansion sleeve, creating a mechanical lock that is resistant to vibration.
Another of Krawiec's patents is a blind fastener with a deformable sleeve. This fastener includes a body, a core bolt, a nut, and a sleeve. The core bolt passes through an axial bore of the body and features an externally threaded portion at its inner end. The nut has an enlarged head, a reduced diameter stem, and a threaded bore for engaging the threaded portion of the core bolt. The sleeve is positioned between the enlarged head of the core bolt and a conically shaped inner portion of the body. In a preferred embodiment, the inner end portion of the sleeve is crimped to the nut, ensuring a secure engagement during the setting of the fastener.
