DETACHABLE HANDLE FOR SIRIUS CREMONE | POLARIS HANDLE
In a market where security has become one of the most important demands of the client, the cremones and handles have evolved towards systems which incorporate security mechanisms which restrict opening of the window via detachable handles.
The market leading SIRIUS DETACHABLE CREMONE from STAC stands out for the standards of quality and innovation which make it a highly desirable product in the market for cremones with removable handles.
In keeping with this trend, clients have been asking for smaller, sleeker mechanisms for handles with spindles and so STAC has added the POLARIS DETACHABLE HANDLE to their hardware range. This new product offers a solid and robust solution for the demanding market of door and window hardware.
The Polaris detachable handle has the following innovative features:
| > Micro-ventilation |
The Polaris detachable handle allows controlled air flow into the internal space in the micro-ventilation position in compliance with the minimum ventilation levels set by the Spanish Building Code (Código Técnico de la Edificación). The micro-ventilation system favours circulation of air and allows for savings without losing the comfort of a fresh environment and without brusque temperature fluctuations.
As the handle reaches the active positions an audible click allows the user to know that the handle is being used correctly.
Both products stand-out from other detachable cremones and handles thanks to the following characteristics:
The new Sirius cremone has a base component over the backplate in where the generally squared cavity that is use to pull has been changed to a “TT” shape double slot.
We have developed a similar component for the handle but with the corresponding counter shape so that the end user fits the handle slotting it in to the base and therefore eliminating the risk of it falling off.
The new double “T” transmission components completely secure the handle over the base making it possible to pull the handle for a casement opening as well as being able to swivel it to tilt the window.
This is another change in this new design. We have developed and integrated in to the assembly a retaining component that impedes the handle coming out of the grooves during normal cremone use and being able to be installed and operative for as long as is required as well as being able to leave the tilted window with the handle in place without any risk of it falling out.
To unblock it, the end user simply lightly presses the retention clip
As a result of the previous points, this has converted together with a base cremone and detachable handle in to a 100% functional cremone if the end user so requires. Therefore the mechanism has been researched from the point of view of cycle resistance. The T mechanism is designed to maximise the contact faces between the handle transmission components and the backplate and at the same time the contact point with the rotation shaft is avoided in order to reduce the torque.
From the inception of the product we considered being able to offer a minimalist mechanism in relation to the cremone base which integrates with the backplate, this being the component that highlights its aesthetic lines.
The channel groove is hidden in the transmission shaft and is imperceptible from the front and is only 4 mm high with respect to the base.
The components have been developed in Zamak so that they can be painted in any of the RAL chart colours for total integration with any aluminium system.
