Title: Helmut K Waibel: Innovator in Impact Printing Technology

Introduction

Helmut K Waibel is a notable inventor based in Fremont, CA (US), recognized for his contributions to impact printing technology. With a total of 8 patents to his name, Waibel has made significant advancements in the design and functionality of impact printers.

Latest Patents

One of his latest patents is the "Impact Printer Platen Support." This invention addresses the challenges faced by serial impact printers by providing a platen that can withstand rapidly repeating, long-duration, high-impact loads without generating extraneous noise. The design includes a central shaft and a cylindrical impact-absorbing sleeve, ensuring that the ends of the shaft are securely captured in seats that can endure high-impact printing forces.

Another significant patent is the "Impact Mechanism for Impact Printer." This mechanism is designed to deliver a printing force to drive a character element against a platen. It features a rockable bail bar constrained to limited angular movement, which is connected to a prime mover. The push rod interconnects the print tip and the bail bar, allowing for efficient delivery of impact forces to the platen while also providing a decoupling mechanism for easy removal of the character element.
