Abstract

The present invention relates to a device for the shutter-like and tilt-down opening, with respect to a fixed frame, of a window or door-window composed of an upper cross-member and a lower cross-member connected by a pair of uprights on one of which handle is rotatably associated. The peculiarity of the device consists in the fact that it compirses box, arranged on one of the uprights, which is provided with means, actuated by the handle, for tensioning at least one traction element such as cable. This at least one traction element can be advantageously constituted by a first and second cable which actuate a plurality of pins for the temporary closure of the window onto the fixed frame and for coupling to an upper hinge for shutter-like or tilt-down opening. The device furthermore comprises a lower spherical hinge which is provided with a friction action for shutter-like opening and with an articulation action for tilt-down opening. The box finally comprises means adapted to prevent the rotation of the handle starting from the tilt-down condition ot the shutter-like position.

Device for the shutter-like and tilt-down opening, with respect to a fixed frame, of a window or door-window composed of an upper cross-member and a lower cross-member connected by a pair of uprights, a handle being rotatably associated on one of said uprights, said device comprising a box, arranged on one of said uprights, which is provided with means, actuated by said handle, for tensioning at least one traction element which actuates a plurality of pins for the temporary closure onto said fixed frame and for coupling to an upper hinge for shutter-like or tilt-down opening, said device comprising a lower spherical hinge with friction means for shutter-like opening and articulated for tilt-down opening, said box comprising means adapted to prevent the rotation of said handle from the tilt-down opening condition to the shutter-like opening condition, said box being composed of a first and second mutually associated half-shell, wherein said tensioning means are constituted by a cam which has a seat for actuation by means of said handle, said cam interacting with a first and a second dowel which have an essentially cylindrical shape, said cam having a width which is approximately equal to the interspace between said first and said second half-shell and having profiles with a different configuration at said half-shells, said cam having, at said first half-shell, a first planar region on which said first dowel rests when the window is closed, an end of said first dowel being accommodated at an adapted seat provided on said first half-shell while the other end interacts with a first wing of a first slider which has an essentially L-shaped configuration, said first slider being slidably associated at an adapted longitudinal seat provided on said first half-shell.

Device for the shutter-like and tilt-out opening of a window or door-window structure (1) with respect to a fixed frame means (34), said device comprising

a first hinge means (68) interconnected between said structure (1) and said fixed frame means (34) which allows pivoting of said structure (1) with respect to said fixed frame means (34) about both a first tilt-out pivoting axis (3) and a second shutter-like pivoting axis (4), said first and second axes being substantially mutually orthogonal, said first hinge means (68) being arranged substantially at a point where said first and second axes intersect,
a second hinge means (52) interconnected between said structure (1) and said fixed frame means (34) which also allows pivoting of said structure (1) with respect to said fixed frame means (34) about both said first and second axes, said second hinge means (52) being arranged substantially on said second pivoting axis (4) at a distance away from said first pivoting axis (3),
releasable connection means (37,45,51) at least temporarily connected between said structure (1) and said fixed frame means (34),
a manipulation handle means (6) rotatably connected to said structure (1), and
traction element means (10,11) and tensioning means (12), said traction element means (10,11) being interconnected between said second hinge means (52) and said tensioning means (12), said traction element means (10,11) also being interconnected between said releasable connection means (37,45,51) and said tensioning means (12), said tensioning means (12) being actuable by said manipulation handle means (6) to thereby controllably tension said traction element means (10,11) for selectively operating said connection means (37,45,51) and said second hinge means (52) for the shutter-like or the tilt-down opening of said structure (1) with respect to said fixed frame means (34),
wherein said tensioning means comprises a cam element (12), said traction element means comprising a first spring-loaded traction element (10) and a second spring-loaded traction element (11), said cam element (12) defining a first cam profile (15,22,23) for tensioning said first spring-loaded traction element (10) and a second cam profile (24,25,26) for tensioning said second spring-loaded traction element (11), said first (15,22,23) and said second (24,25,26) cam profiles respectively tensioning said first (10) and said second (11) spring-loaded traction elements simultaneously upon actuation of said manipulation handle means (6).
