English Abstract


There is described a section element for windows or doors
with receptacle compartment, hardware grooves and/or screw coupling
channels for reception of hardware components, wherein the
receptacle compartments, hardware grooves and/or screw coupling
channels are adapted for the selective incorporation of either
rotate-tip hardware components or casement hardware components.
Further, there is described the corresponding frame components and
from structures.
Preferably a main chamber is provided in the inventive frame
kit and frame structure, in which an outreach opening mechanism of
a casement-system can be mounted.
The invention makes it possible, with a single unitary
operating process to obtain two window or door types which in their
operation are absolutely different, namely rotate-tip or casement
windows.


Claims

Note: Claims are shown in the official language in which they were submitted.


CLAIMS
1. Section element for windows or doors, with receptacle
compartments, hardware grooves and/or screw coupling channels or
channels for conventional window or door hardware, thereby
characterized, that the receptacle compartment, hardware grooves
and/or screw coupling channels are designed or constructed for the
selective installation of rotate-tip hardware components or
casement hardware components.
2. Frame kit, inclusive of the window frame-, windowsill
frame- and as the case may be, glass holder frame section with
respective receptacle compartments, hardware grooves and/or screw
coupling channels for conventional window-or door hardware, thereby
characterized, that the receptacle compartment, hardware, grooves
and/or screw coupling channels are designed or dimensioned for the
selective mounting of rotate-tip-hardware components or casement-
hardware components.
3. Frame kit according to claim 1, thereby characterized,
that a main chamber (19) is provided, into which an opening
mechanism (18) of a casement system can be installed.
4. Window or door frame structure with hardware, inclusive
of section elements according to claim 1, sealing elements and
rotate-tip hardware components or casement hardware components.
5. Window-or door frame structure according to claim 4,
thereby characterized, that a chamber (19) is provided, which
is adapted to receive a mechanism (18) for the outward opening of
a casement system.
