Description

[0001] HARDWARE FOR TILT AND TURN WINDOWS DESCRIPTION

[0002] Technical field

[0003] The present invention falls within the technological sector of construction, specifically in the area of ​​window and door fittings, such as doors and windows. More specifically, the invention relates to a hinge for tilt-and-turn windows and doors that allows the use of larger and heavier doors and windows than those permitted by prior art fittings.

[0004] Background

[0005] In the window and door industry, particularly for tilt-and-turn windows, there are several profile channel systems that define the dimensions of the profiles and the resulting channels. For example, one such system is called the "European system" or, equivalently, the "European channel." The dimensions of these channel systems determine, among other things, the dimensions of the hardware that makes up the window and door frame and, therefore, the maximum performance characteristics, such as size and weight, of the windows and doors in which the hardware is installed.

[0006] It is desired, for the predetermined dimensions of each channel system, to be able to mount tilt-and-turn enclosures, both doors and windows, with increased performance, for example, larger size and greater weight.

[0007] Summary description of the invention

[0008] The present invention solves the problems referred to in the background section by means of a hinge for a tilt-and-turn window system which, according to independent claim 1, comprises two pivot angles, one lower and one upper, both intended to be mounted on a sash profile of an active sash of a tilt-and-turn window system, and both configured to lock the active sash in the closed position, the lower pivot angle being further configured to allow the active sash to tilt. The lower pivot angle comprises: a lower angle bracket, intended to be movably mounted on a lower corner of the sash profile of the active sash; a lower metal pointer, movably housed in the lower angle bracket; and a lower metal locking point.The upper redirection angle comprises: an upper angle bracket, designed to be movably mounted on an upper corner of the active leaf's profile; and a metal upper pin, movably housed within the upper angle bracket. The fitting also includes a first upper strike plate, designed to be fixed to a frame profile of the enclosure frame, and which includes: an upper pin housing for the upper pin; and a lower strike plate, fixed to the frame profile, which incorporates both a lower pin housing for the lower pin and a lower locking housing for the lower locking point, to provide tilting of the active leaf on the lower enclosure and allow oscillation of said active leaf.The hardware also includes espagnolette bolts, as well as a bidirectional transmission box to operate the espagnolette bolts and locking points, moving the bolts symmetrically in opposite directions around a horizontal axis of symmetry of the window. The pivot angles are adjustable by the espagnolette bolts, causing the pins to emerge from their corresponding angle, penetrate the corresponding strike plate, and lock the sash. The upper pin and the first upper strike plate, as well as the lower pin and the lower strike plate, serve to lock the active sash in the closed position, while the lower locking point and the lower strike plate allow the active sash to swing open.

[0009] Other optional advantageous features are explained later, in the detailed description of an exemplary embodiment, and in the claims. In particular, the invention also relates to a tilt-and-turn enclosure, such as a door or window, incorporating the described fitting.

[0010] The fitting of the present invention is compatible with various channel systems, including the aforementioned European system, so that, in all channel systems, it provides reinforced performance that allows for an increase in the dimensions and weight of the enclosures.

[0018] Detailed description of an implementation example

[0019] Next, with the aid of the aforementioned accompanying Figures 1-6, a detailed description is provided of a preferred embodiment of a hinge for a tilt-and-turn enclosure (1), such as a door or window, according to the present invention. The figures, without loss of generality, depict an example of the hinge of the invention applied to a tilt-and-turn window-type enclosure (1).

[0020] The tilt-and-turn enclosure (1) in which the hardware of the invention is mounted comprises a frame and two sashes. Of the two sashes, one is an active sash, i.e., designed to bear a handle for selectively opening the enclosure (1) in a tilt-and-turn fashion, opening in a tilt-and-turn fashion, and closing manner, while the other sash is a passive sash, i.e., without a handle. The enclosure (1) also includes a profile system which, as is conventional, comprises: a sash profile (2) for each sash, and a frame profile (3). The profile system may be a European system, or any other system. The frame profile (3) forms part of the frame, while each sash profile (2) forms part of its corresponding sash. The hardware comprises two redirect angles – lower (4) and upper (5) – which are mounted, internally and superiorly, respectively, in corresponding corners of the sash profile (2) of the active sash.Each of the redirect angles (4, 5) is mounted, preferably by direct mounting, i.e., by means of a form-lock fastening system (6), for example, a clip, in a channel of the leaf profile (2) of the active leaf, see figures 5 and 6. The term “direct mounting”, referring to the redirect angles (4, 5), means that it is not necessary to machine grooves at the ends of the leaf profile (2) to leave the channel open and insert the redirect angles (4, 5), but rather each of the redirect angles (4, 5) is positioned on the channel and, by means of a twist, is inserted directly into said channel, being fixed by means of a form-lock fastening, using, as a fastening system (6), an additional deformable plastic piece to adjust according to form-lock.

[0021] Each of the redirection angles (4, 5) comprises an angle bracket (7, 16), intended to be movably mounted on a corner of the sheet profile (2). One of the angle brackets (7, 16) is a lower angle bracket (7) of the lower redirection angle (4), and the other is an upper angle bracket (16) of the upper redirection angle (5). Each redirection angle (4, 5) also comprises a respective metal pointer (9, 17), made of steel, for reinforcement, housed in the corresponding angle bracket (7, 16), i.e., a lower pointer (9) for the lower redirection angle (4), and an upper pointer (17) for the upper redirection angle (5). Finally, the lower redirection angle (4) also has a lower locking point (10), and the upper redirection angle (5) may optionally include an upper locking point (18).The upper redirection angle (5) serves to lock the active leaf in the closed position, while the lower redirection angle (4), in addition to locking the active leaf in the closed position, also serves to allow the active leaf to swing.

[0022] Specifically, with regard to the upper redirect angle (5), for closing, the fitting additionally comprises a first upper strike plate (14), also called a "pointer strike plate", fixed to the frame profile (3) and including an upper pointer housing (not shown), to house the upper pointer (17), as well as, optionally, a second upper strike plate (8), which includes an upper locking housing (not shown), to house the upper locking point (18).For its part, with regard to the lower redirection angle (4), for effecting closure, the fitting comprises a lower strike plate (11), also called a “tilting strike plate”, fixed to the frame profile (3), and which incorporates both a lower pointer housing (not shown) to house the lower pointer (9), as well as a lower locking housing (not shown) to house the lower locking point (10), providing tilting, on the lower strike plate (11), of the active leaf and allowing oscillation of said active leaf.

[0023] The fitting also includes espagnolettes (12), as well as a bidirectional transmission box (13), to operate the espagnolettes (12) and the lower locking point (10), as well as, where applicable, the upper locking point (18), moving the espagnolettes (12) symmetrically in opposite directions with respect to a horizontal axis of symmetry of the window (1).

[0024] The first upper strike plate (14), and its corresponding upper pivot (17), provide added security when the window is in the closed position. In particular, the redirect angles (4, 5) are displaced by the bolts (12), causing the pivots (9, 17) to emerge from their corresponding angle (7, 16) and penetrate their strike plate (11, 14). That is, the first upper strike plate (14) engages the upper pivot (17), and the lower strike plate (11) engages the lower pivot (9), thus locking the closure (1).The locking points (10, 18) are movable thanks to internal plates (15), which are connected to said locking points (10, 18), and which are draggable by the bolts (12), to transmit the movement of the transmission box (13) in a first direction which, as shown in the embodiment of the figures, is a vertical direction, in a movement of the locking points (10, 18) in a second direction different from the first direction which, as shown in the embodiment of the figures, is a horizontal direction.

[0025] The bidirectional transmission box (13) allows operation of both the lower redirection angle (4) and the upper redirection angle (5), thereby activating the pointers (9, 17), both upper (17) and lower (9), to reinforce the corners, both upper and lower, respectively.
