OEM Development Case for Building Fixtures: Pull Handle with Assist Mechanism

By arranging the built-in arms in a cross configuration, parallel movement of the handle is possible! Achieves approximately 40% reduction in initial operating force.

In recent years, sliding sash windows have felt heavy to open and close, haven't they? This is because sash windows have been getting larger year by year, and there has also been a demand for improved water and air tightness. In response, our company has developed a "pull handle with assist mechanism" that can be operated with light force, aiming to make life more comfortable for children and the elderly. The design concept is "reducing the initial operating force." When the handle is slid, a built-in arm protrudes, and a tip roller kicks against the sash frame to assist with the initial operation. [Background and Issues] ■ As sash windows have been getting larger year by year, and with the demand for improved water and air tightness, recent sliding sash windows have felt heavy to open and close. *For more details, please refer to the PDF document or feel free to contact us.*
