Introduction
Thomas Granacher is a notable inventor based in Schaan, Liechtenstein. He has made significant contributions to the field of power tools, holding a total of four patents. His innovative designs focus on enhancing the functionality and safety of hand-held power tools.
Latest Patents
One of Granacher's latest patents is a slip clutch for a hand-held power tool. This invention serves to uncouple a tool socket from a driving motor in the event of an overload. The design features an annular running surface with cams projecting radially inward. The slip clutch consists of a set of pairs made up of a preloaded coil spring and a pawl. The coil spring presses the head of the pawl outward onto the running surface. The pawl includes a sheet-metal strip, with one section bent into a hollow prism that is annularly closed, except for a gap, to form the head. An insert is placed into the gap to fill it.
Another significant patent is related to a temperature-controlled fan with delayed shut-off. This invention pertains to a combustion-driven working tool that includes a combustion chamber, a piston guided in a cylinder, and an ignition system for igniting fuel. The fan is designed to ventilate the combustion chamber, with its running time and speed adjustable based on measured temperature. This allows for optimal ignition behavior under varying working conditions, particularly with changing external temperatures. A first temperature sensor measures the combustion chamber temperature, while a second sensor measures the external temperature to aid in calculating the fan's cooling time and speed.
