Title: Subashchandra G Rai: Innovator in Lock Mechanisms

Introduction

Subashchandra G Rai is a prominent inventor based in Karnataka, India. He has made significant contributions to the field of lock mechanisms, holding a total of 12 patents. His innovative designs have enhanced the functionality and security of locking systems.

Latest Patents

Among his latest patents is a pushbutton mechanism for locksets. This exemplary mechanism is designed for use with a lockset that includes a spindle and a plunger. It features a first component that is rotationally coupled with the plunger and axially coupled with the spindle. This component can rotate between locking and unlocking orientations. The second component is rotationally coupled with the spindle and can move axially between a depressed and projected position. The cam interface correlates the rotation of the first component with the axial displacement of the second component. Another notable patent is the power boost module, which relates to operating a door closer assembly. This method involves a closer body, a pinion, and a motor with a bidirectional clutch. The clutch allows the pinion to rotate in both directions without transmitting that rotation to the motor shaft. A sensor detects the pinion's rotational position, and a controller compares it with a desired position to drive the motor accordingly.
