Window handles
Window handles automatically retain the design of a room’s door fittings in standard practice, obviously enough. Our range of products provides a great many compelling answers to questions of both form and functionality – on offer, for instance, are window handles in over 35 design variants on oval or angular roses boasting a wealth of differing technical functions for specific areas of application.
Window handles for special requirements
New: Flush window handle
Set a stylish accent, or integrate minimally reserved into the surrounding space. FSB combines the simplest design with the highest level of technical sophistication, complementing the existing flush portfolio with an innovative solution for wooden and metal windows that is as elegant as it is functional.
Lockable windows handles
Lockable FSB window handles are a reliable hardware solution for burglary-resistant elements that also meet the security criteria and design requirements of the RAL quality standards and DIN EN 13 126-3, or in some cases even significantly exceed them.
Window handles with push-to-unlock mechanism
Press the window handle, turn and open the window: FSB window handles with push-to-unlock mechanism are recommended, e.g. B. for children's rooms, in which the window opening is to be made more difficult. An optional unlocking button enables additional internal and external security.
Window handles for narrow profiles
Standard window handles do not harmonise adequately with narrow window profiles. FSB has slimmed down the rose fitted to such profiles in such a way that it no longer extends beyond the glazing fillet, thus according perfectly with the window’s restrained overall appearance.
Window handles with flush rose
It is not out of modesty that we set our fittings so deep as to be virtually imperceptible. Rather, FSB is echoing trends in architecture towards paring structures and functional detail down to what is absolutely necessary. They are the perfect companions to our flush-fitting lever/lever sets and flush pulls.
Plug-in handles
What a difference less can make! With its radically pared-down rose, the FSB plug-in handle is ideal for any window profile – whether timber or metal. There is nothing reductionist about the range of variants available, though: awaiting assembly are 37 different handle designs in Aluminium, Stainless Steel, Brass and Bronze.
Technical information
FSB's newly conceived ball-catch mechanism – a particularly rugged fusion of components in hardened and tempered steel, high-grade steel and glass fibrereinforced plastic – is further enhanced by its compact design and ideal mode of assembly.
The new system is operated in the same way as FSB's long-standing ball-catch mechanism for roses, employing both tactile and audible means to aid dependably correct operation of the window to ergonomic effect. Key to this is the way the handle can be felt and heard clicking into position at 90° intervals when the window is opened, closed or tilted. FSB’s fine new hardware is engineered to deliver 25,000 operations/150,000 click-stop events (180° turn-and-tilt cycles), earning it the highest quality rating for operating endurance of 5/180 under EN 13 126-3. The RAL Quality Assurance Association has re-aligned its requirements with the criteria set forth in DIN EN 13 126-3, meaning that hardware merely now needs to endure 10,000 tilt-turn cycles in 180° mode to qualify for the RAL quality kitemark.
EN 13 126-3 defines requirements for window handles that serve to ensure unchanging quality and fitness for function over a great many years.
Engineered to deliver sustainable longterm functioning, the mechanism comprises steel ball bearings and attendant steel springs housed in recesses within the rose assembly. Bearings and springs are arranged in double formation around a high-grade steel disc that has four recesses for this purpose and is rigidly attached to a dedicated adaptor. The resultant turnably fixed ball-catch mechanism ensures that each act of repositioning the window handle can be felt and heard. The actual window handle is fitted to the front of the adaptor. Running axially along the inside of the latter, meanwhile, is a square-sectioned spindle that can be variably positioned to facilitate flexible spindle projections. A cup point screw is used to secure the window handle to its spindle once the rose assembly has been fitted.
Tilt-to-turn
Special-action lockable handles are required in conjunction with the “tilt-toturn” window drive mechanisms often fitted in schools, offices and hospitals to prevent unauthorised operation whilst guaranteeing adequate ventilation.
Please note: windows with a “tilt-to-turn” action are fitted with non-standard-conformant window drive mechanisms in order to ensure the function described. On its own, a window handle equipped accordingly does not fulfil this function. Please take this into account at the planning and tendering stages.
Tilt-to-turn window handles do not conform to either the RAL quality standard or DIN EN standards 1627 to 1630, furthermore.
