BACKGROUND OF THE INVENTION
[0001] The present invention relates to a window or door frame, including an improved opening
system.
[0002] More specifically, the present invention relates to a window or door frame, which
can be used in buildings having, large glazed surfaces, in which the problem of properly
cleaning the outer surface of the glazed panels frequently occurs.
SUMMARY OF THE INVENTION
[0003] The aim of the present invention is to provide such a window or door frame construction
which has been specifically designed for use in buildings having large glazed surfaces,
to facilitate the cleaning of the outer surface of the glazed panels.
[0004] Within the scope of the above mentioned aim, a main object of the present invention
is to provide such a window or door frame construction which is very strong and reliable
in operation.
[0005] Another object of the present invention is to provide such a window or door frame

[0006] According to one aspect of the present invention, the above mentioned aim and objects,
as well as yet other objects, which will become more apparent hereinafter, are achieved
by a window or door frame construction, including an improved opening system, having
at least an openable glazed panel, characterized in that said panel can be selectively
turned either about a horizontal top side thereof or about a horizontal bottom side
thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] With reference to the number references of the above mentioned figures, the window
or door frame construction, according to the present invention, which has been generally
indicated by the reference number 1, comprises a glazed panel 2, mounted on a fixed
framework 3, applied to a wall 4.
[0009] More specifically, the glazed panel 2 comprises a panel frame 5, coupled to the fixed
frame 3 by bottom pivot means, allowing the glazed panel 2 to turn about its bottom
horizontal side 6, as well as top pivot means allowing the glazed panel 2 to rotate
about its horizontal top side 7.
[0010] Moreover, the glazed panel 2 is coupled to the fixed framework or frame 3 by two
pairs of coupling levers, respectively a top coupling lever 8 and a bottom coupling
lever 9.
[0011] The rotary movement of the glazed panel 2, with respect to the bottom or top pivot
means, can be selectively controlled by control means for controlling the pivot means,
i.e. for respectively engaging and disengaging the pivot means, alternately, by engaging
the bottom pivot means and simultaneously disengaging the top pivot means.
[0012] Thus, it is possible to rotate the glazed panel about the bottom side 6 thereof (figure
2), or engage the top pivot means and, simultaneously, disengage the bottom pivot
means, to allow said glazed panel to rotate about the top side 7 thereof (figure 3).
[0013] The top lever pair 8 will limit the opening of the glazed panel 2, as it is rotated
about the bottom side 6 thereof, whereas the bottom lever pair 8 will hold the glazed
panel 2 at an opened position or condition thereof, as it is rotated about the top
side 7.
[0014] Advantageously, each top lever 8 operates as urged by a resilient element, such as
a coil spring 9, held in the side upright of the fixed frame 3, to dampen the opening
of said glazed panel.
[0015] The above mentioned control means comprises, in particular, a lever 10 which can
be rotated to at least three positions, i.e.: a closed window position, an open window
position, in which the window is open at the top thereof, with a wasistas type of
opening pattern, and a bottom opened window position.
[0016] In particular, as the lever 10 is rotated, it will control a plurality of elongated
elements, which are flexible at least at the corners of the fixed frame 3, and associated
with the pivot means.
[0017] The bottom pivot means comprise at least a pair of bottom pins 11, each associated
with a respective bottom rod 12 in turn coupled to the control lever 10.
[0018] The top pivot means comprise, in turn, at least a pair of top pivot pins 13, each
of which is associated with a respective top rod 14.
[0019] Each said top rod 14 is associated with a corresponding side rod 15, which can slide
along the upright of the fixed frame 3, through a flexible blade element 16 designed
for transmitting the motion of the side rod 15 to the respective top rod 14.
[0020] As is shown, each side rod 15 is coupled to a respective bottom rod 12 by a flexible
blade element 17, designed for transmitting motion from'the bottom rod 12 to the respective
side rod 15.
[0021] The control lever 10 is operatively kinematically coupled to the bottom rods 12,
thereby, for each rotation of said control lever 10, the two rods 12 will be oppositely
driven, i.e. either both outwardly, or both inwardly.
[0022] The control lever 10 defines at least three operating positions: a closed window
position, in which all the bottom pivot pins 11 and top pivot pins 13 engage respectively
recesses formed in the frame 3 and the glazed panel 2 is closed; a position in which
the window is open at the top thereof, with a wasistas type of opening pattern, in
which the bottom rods are urged by the rotating lever 10 outwardly so as to cause
the bottom pivot pins 11 to engage the respective recesses of the fixed frame, whereas
the top pivot pins 13 are withdrawn so as to disengage the top recesses; a position
in which the window is open at the bottom thereof, where the bottom pivot pins 11
are withdrawn so as to disengage their respective recesses, whereas the top pivot
pins 13 engage the respective recesses of the fixed frame.
[0023] In the bottom opened condition of the window, as shown in figures 3 and 5, it is
possible to easily access the outer surface of the glazed panel from inside the building,
to easily clean said outer surface.
[0024] In this connection, it should be pointed out that the opening and closing operations
of the movable window wings would be facilitated by a perfect balancing of said wings,
afforded by the device of the invention.
[0025] This feature would allow to greatly reducing the exposed to the view surfaces of
the wing uprights and cross members.
[0026] It has been found that the invention fully achieves the intended aim and objects.
[0027] In fact, the invention provides a window or door frame, specifically designed for
application in buildings having large glazed surfaces, in which the downward and inward
opening of the glazed panel allows to easily clean the outer surface of said glazed
panel, from the inside of the building.
