TOK Corporation Develops Remote Lock Release Clutch Mechanism
TOK Corporation (Headquarters: Itabashi-ku, Tokyo, President: Keisuke Yoshikawa) has successfully developed a new “Remote Lock Release Clutch Mechanism.” This innovative mechanism enables the remote unlocking of a rotating shaft with a simple push of a button.
This mechanism is built upon the company’s extensive experience and technology in developing mechanical components, particularly one-way clutches. It has been designed as a general-purpose mechanism technology, adaptable to various applications. As an example of its potential, TOK Corporation has been involved in the entire process—from planning and design to product commercialization and market launch—for medical equipment, in collaboration with relevant stakeholders.

Mechanism Details
The Remote Lock Release Clutch Mechanism integrates two one-way clutches with hydraulic control, allowing for remote switching between locked and free states. When the operation button is pressed, the rotating shaft is unlocked (free state); releasing the button automatically engages the lock. The hydraulic control connected to the release button facilitates the simultaneous unlocking of both clutches.
Designed for single-handed operation, the mechanism incorporates a hydraulically controlled wire cord to ensure stable transmission of clutch action. A key feature is the ability to position the release button remotely, enabling lock/free switching even when the operating part is separated from the movable part.
This mechanism is envisioned for products that require repeated adjustments of position or angle, such as flexible arms and smartphone stands, where the adjusted state needs to be maintained. Adjustments are made by unlocking the mechanism, which then automatically locks into place once positioned, offering intuitive operation. Furthermore, as it does not require power or electronic control, the structure is simplified, contributing to overall product compactness and lighter weight. This allows for flexible design tailored to installation conditions and ease of use. The technology related to this mechanism is currently patent pending.

What is a One-Way Clutch?
A one-way clutch is a mechanical component that transmits power in only one direction. It is used to prevent reverse rotation or to engage/disengage power transmission. TOK Corporation has been designing and manufacturing one-way clutches for over 30 years, providing mechanism technology for rotational control and operational state switching to various product development fields.

Developer’s Comment
The development of this technology is rooted in TOK Corporation’s accumulated expertise in one-way clutch design. The focus was on creating a versatile mechanism technology that is independent of operating conditions and installation environments. The company aims to continue leveraging its strength as a manufacturer of mechanical components that do not rely on electricity in various forms moving forward.
