The challenge
In our previous versions of the criterion B positive mechanism we went along with EN 1906, which prescribes a return action on the door handle so as to achieve a predefined position by means of spring pre-tensioning. At the same time, EN 1906 is silent on the actual return position of the handle and does not prescribe anything specific in this respect.
Practice hitherto
Anything not governed by some form of rule is all too often per - emptorily swept under the carpet. That’s what’s happened here too: to date none of our fellow-competitors has come up with a solution that deals with the return action stipulated from an aesthetic point of view. It’s high time handles were really straightened out!
Our solution
FSB wouldn’t be FSB if we did not apply the aspect of a return action to architecture and hence harness it for a product that is wholly thought through and which, once fitted to the door, meets the most exacting aesthetic demands long-term. By suitably fashioning the bearing areas for the positive mechanism springs, the carrier plate and the bump stops in the base, by delivering positive locking and an exact fit of the handle in this mechanism, and by turning all the constituent parts into a smoothly interacting whole, we quickly set about ensuring that, assuming proper fitting, the handles in AGL® furniture will always come to rest horizontally. That’s really the way it needs to be, after all.
