Optimised Form Fit for System Ankle Joints in 16 and 20mm System Widths
We are pleased to present an important new development in our system ankle joints: The system joints in the 16 and 20mm system widths now feature a completely redesigned connection between the cover plate and the joint’s upper part. Both system widths have now been converted to the precise pre-milled form fit without feather keys. This will be the basis for the plug + go modularity for these system widths in the future.
What is Improved
Cut-outs on the sides of the innovative form fit allow for a precise fit of the cover plate and joint’s upper part. This means that the previous feather keys can be omitted entirely. This design makes assembly easier, as there are no more small parts to be inserted or checked. The new connection is more durable and even more reliable in day-to-day use. In addition, the optimisation prevents minor movements that previously caused occasional grinding noises.
Important: The new form fit is not compatible with previous components. Joint’s upper parts and cover plates with feather keys cannot be combined with the new components. The assembly/lamination dummies for the 20mm system width have been adapted accordingly.
Restoring plug + go Modularity
Once all affected joints have been converted, you can again take full advantage of the plug + go modularity within the respective system width.
The NEURO CLASSIC‑SWING and NEURO CLASSIC‑SPRING system joints, which do not have plug + go modularity, will be converted as before. It is still possible to file down the foot piece that is explained in the online tutorials.
You can find further information on the FIOR & GENTZ website and in the respective instructions for use and maintenance plans. The product catalogue "System joints and System Side Bars" contains comprehensive tables showing previous components with feather keys and the new variants without feather keys.
