Title: Alfred Tobler: Innovator in Fastening Technology
Introduction
Alfred Tobler is a notable inventor based in Erlen, Switzerland. He has made significant contributions to the field of fastening technology, holding a total of 3 patents. His innovative designs have enhanced the efficiency and effectiveness of fastening elements used in various applications.
Latest Patents
One of Tobler's latest patents is a fastening element assembly with a deformable sleeve. This assembly consists of a nail-like fastening element and a deformable sleeve that is displaceably secured on the fastening element shank. It is designed to secure sheet metal plates to a base material of variable strength. The sleeve has an outwardly extending flange at its leading end. When driven into a receiving material, the sleeve is displaced rearwardly along the shank, which widens conically toward the head. This design allows for radial expansion of the sleeve, converting excess energy during the driving step into deformation work acting on the sleeve.
Another significant patent is for a fastening member intended for securement into hard materials such as concrete, masonry, and rock. This fastening member features an axially extending shank with a drilling head at its leading end and a thread adjacent to its trailing end for connecting a load. A device on the shank engages with a tool to drive the fastening member into the receiving material. Initially, it drills a blind bore, and then an explosive powder charge drives the member into its final position.
