The Joseph Giles unique rota-bearing sprung rose is a mechanism which is concealed within the rose of a lever handle. The Sprung rose helps to support and control the movement of the lever, allowing for a more precise operation.
The Joseph Giles unique rota-bearing sprung rose allows for the seamlessly simplified application of even our heaviest pair of solid brass handles, while the concealed horizontal stop ensures that our lever handles always sit perfectly horizontal. Our unique sprung rose design brings smooth, silent and flawless operation to all Joseph Giles levers.
Designed to deliver a flawless performance, the unique rota-bearing sprung rose has been tested to operate for over 200,000 cycles with no wear or deterioration to its function, making it completely maintenance-free for its lifetime.
As our handles are made from solid brass, they are often too heavy for general latch mechanisms. One of the most beautiful things about the unique rota-bearing sprung rose is that it allows even our heaviest pair of levers to sit completely straight and maintain a centrally fixed axis of rotation.
The mechanism allows for much easier fitting of our handles on any door that has a pre-existing latch.
Initial idea is conceived
The first draft of the sprung rose in completed in January
After 10 months of trying to source materials to make the product oversees, we decide to take a step back and revisit why we began this project
Design review led to us changing the design of the product and deciding to source the materials in the UK.
5 months of research and development has been completed
The Sprung rose design is now completed
The Sprung rose mechanism is officially launched to the market and is now available with all of our lever handles, thumb turns and doorknobs.
