Controller for an operating device with braking functionality
The patent US12072003B2 describes a controller designed to manage an operating device that features an operating member, which can be pushed by an operator. This operating member is supported by biasing means that return it to its original position. The controller utilizes detecting means to monitor the distance the operating member moves and generates a detection signal based on this movement. When the operating member is pushed to a predetermined retracted position, the controller activates braking means to hold the member in place. Conversely, if the operating member moves back due to a clearance in the drive transmission system, the controller will deactivate the braking means, allowing the member to return.
The claims further elaborate on the drive transmission system, which may include a coupling joint with two rotating joints or a system of meshing gears. The controller is designed to respond to detection signals indicating movement in the return direction due to clearances or backlash in these systems. Additionally, the operating device may incorporate a rotating member that is linked to the operating member through a rack-and-pinion mechanism, with the detecting means potentially being a rotation angle sensor or a linear position sensor. The patent also allows for the predetermined retracted position to be adjustable, enhancing the flexibility of the operating system that includes both the controller and the operating device.
