Title: The Innovative Mind of Helmut Vollmer
Introduction
Helmut Vollmer, an accomplished inventor based in Balzers, Liechtenstein, has made significant contributions to the field of engineering through his innovative designs and patents. With two patents to his name, Vollmer demonstrates a keen understanding of mechanical principles, particularly in the area of dowel assembly systems.
Latest Patents
Vollmer's latest patents reflect his expertise in creating solutions that enhance performance and safety. One notable patent is for a "Means for maintaining axial stress on a dowel assembly." This innovation features a dowel assembly designed to be anchored in a borehole of a receiving material. It includes a uniquely shaped container that sits around the axis of the borehole, allowing it to maintain pressure even when the initial force between the dowel assembly and the receiving material begins to relax. The container is constructed from two parts, where one part can telescope into the other. Importantly, it is filled with an expandable hydraulic mass that activates upon contact with a reaction liquid, which can be introduced by immersing the container in water. This innovative feature ensures sustained force on the dowel assembly, enhancing its reliability in construction applications.
Another key patent introduced by Vollmer is the "Expansion Dowel," which comprises an axially elongated sleeve and an expansion body. This design allows for the expansion of at least an axially extending part of the sleeve, providing a secure fitting. The expansion body includes an annular shaped constriction, facilitating deformation once specific force thresholds are reached. This innovation provides versatility and strength, critical for various applications in construction and engineering.
