It should be noted that the term "window structure" in this application is to be understood in a broad sense to refer to any openable and closable structure, including but not limited to windows, doors, etc.

The following describes the implementation of the examples of the present application with reference to the drawings.

As shown in fig. 1 and 2, the foldable and tiltable window structure includes a frame 1, a first window 2, a second window 3, and a tilting drive 4, an inner space of the frame 1 can be covered by the first window 2 and the second window 3 together, a part of the inner space can be opened by sliding the second window 3, and the entire inner space can be opened by tilting the first window 2 and the second window 3 by using the tilting drive 4.

As shown in fig. 1, 2, 10 and 18, the second window 3 includes a second transparent plate 301 and a second window frame surrounded by two second longitudinal bars 302 and two second cross bars 303, which is fixed to the peripheral edge of the second transparent plate 301 to support the second transparent plate 301.

The second transparent plate 301 shown in fig. 1 and 2 is a square plate, which may be made of glass, and the second window frame is fixed on the inner side surface of the second transparent plate 301, so that on one hand, the outward outer side surface of the second transparent plate 301 is smooth without a convex structure, and on the other hand, the second window frame is conveniently connected with the first window 2 in a sliding manner.

In some embodiments, as shown in fig. 15, the second window 3 is slidably connected to the first window 2 through a sliding rail 5, unlike the prior art in which the sliding rail 5 is disposed between the frame 1 and the window, the sliding rail 5 is disposed between the first window 2 and the second window 3, and the sliding rail 5 is independent of the frame 1, so that the sliding rail 5 does not limit the first window 2 and the second window 3 to be turned over.

In the example of fig. 15, a set of slide rails 5 are provided on opposite sides of the first window 2 and the second window 3, respectively, each set of slide rails 5 including a first rail 501 fixed at a longitudinal side edge of the first window 2, a second rail 502 fixed at a longitudinal side edge of the second window 3, and a retractable slide rail 504 provided between the first rail 501 and the second rail 502, the first rail 501, the second rail 502, and the retractable slide rail 504 each extending in a longitudinal direction of the first window 2 or the second window 3.

As further shown in fig. 15 and 22, the second rail 502 may be fixed on the inner side surface of the second vertical rod 302, where the second rail 502 includes a first side plate 5021, a second side plate 5022, and a connecting plate 5023 connected between the first side plate 5021 and the second side plate 5022, and the first side plate 5021 and the second side plate 5022 are substantially parallel, so that the cross section of the second rail 502 is substantially U-shaped, the first side plate 5021 is located outside the first transparent plate 201 and fixedly connected with the second vertical rod 302, and the second side plate 5022 is located inside the first transparent plate 201 and inserted into the guide groove 503, and thus the second rail 502 and the first rail 501 are in a plug-in fit.

As shown in fig. 23 and 24, the telescopic slide rail 504 is located in the guide groove 503, and the telescopic slide rail 504 includes a plurality of sliding sections which are sequentially slidably connected, so that the plurality of sliding sections can relatively slide, thereby realizing the telescopic movement of the telescopic slide rail 504. The innermost sliding joint is fixedly connected with the first guide rail 501, and the outermost sliding joint is fixedly connected with the second guide rail 502, so that the second guide rail 502 can slide along the guide groove 503 relative to the first guide rail 501, and the telescopic sliding rail 504 stretches and contracts along with the sliding of the second guide rail 502, so that the sliding connection of the first window 2 and the second window 3 is realized. By providing two sets of sliding rails 5, the sliding of the second window 3 is made smoother.

The window structure of this application makes this application can have closed state and different open state through setting up two sets of slide rails.

Fig. 1 and 2 are schematic views of the window structure in a closed state, i.e. the second window 3 is not slid towards the first window 2, and the first window 2 and the second window 3 are in an unfolded state.

Fig. 3 and 4 are schematic views of the window structure in a first sliding open state, i.e. the second window 3 slides a first distance towards the first window 2, the first window 2 and the second window 3 being in a partially overlapping state.

Fig. 5 and 6 are schematic views of the window structure in a second sliding open state, i.e. the second window 3 slides towards the first window 2 by a second distance, the first window 2 and the second window 3 are in a partially overlapped state, the second distance is larger than the first distance, and the open space in the second open state is larger than the open space in the first open state.

Fig. 7 and 8 are schematic views of the window structure in a third sliding open state, i.e. the second window 3 slides towards the first window 2 by a third distance, the first window 2 and the second window 3 are in a fully overlapped state, the third distance is greater than the second distance, the third distance is approximately equal to the longitudinal width of the second window 3, and is also the maximum sliding travel of the second window 3, and the open space in the third open state is greater than the open space in the second open state.

When the second window 3 slides to a different position, an additional auxiliary positioning means may be used to keep the second window 3 at a corresponding position, for example, an operator may hold the second window 3 by hand to prevent the second window 3 from sliding down.

In order to achieve that the second window 3 is kept in any position within the sliding stroke without the aid of external forces, in some embodiments, as shown in fig. 2, 4, 6, 8, the window structure of the present application further comprises an elastic assembly 6 for providing an upward pulling force to the second window 3, the elastic assembly 6 being connected between the first window 2 and the second window 3, the upward pulling force of the elastic assembly 6 to the second window 3 being substantially equal to the weight of the second window 3, so that the pulling force can keep the second window 3 in any position within its sliding stroke, such as keeping the second window 3 in the position shown in fig. 4 or 6, without the need of external forces to prevent the second window 3 from sliding off.

In addition, because the pulling force of the elastic component 6 basically counteracts the gravity of the second window 3, an operator can easily slide the second window 3 upwards by applying a small force, and the operation is labor-saving and convenient.

Optionally, as further shown in fig. 2, 4, 6 and 8, the elastic component 6 includes a plurality of coil springs 601, a plurality of coil spring shafts 602 are disposed on the first window 2, one ends of the plurality of coil springs 601 are respectively wound on the plurality of coil spring shafts 602, and the other ends of the plurality of coil springs 601 are connected with the second window 3.

In the example of fig. 15 and 18, a plurality of coil spring shafts 602 are provided at the lower end of the first side rail 202 of the first window frame, the plurality of coil spring shafts 602 are sequentially spaced from top to bottom, the plurality of coil spring shafts 602 are covered by a housing 603, the upper ends of the plurality of coil springs 601 are wound around the plurality of coil spring shafts 602, respectively, and the lower ends of the plurality of coil springs 601 extend out of the housing 603 and are connected to the second cross bar 303 below the second window frame.

Optionally, the window structure includes two sets of elastic components 6, where the two sets of elastic components 6 are respectively disposed on opposite sides of the first window 2 and the second window 3, so as to provide symmetrical pulling forces to the second window 3 from two sides of the second window 3, and a sum of the pulling forces of the two sets of elastic components 6 on the second window 3 is substantially equal to a gravitational force of the second window 3.

To prevent the second window 3 from being turned out due to improper force application during the upward sliding of the second window 3 by an operator, in some embodiments, as shown in fig. 4, 6, 15, 16 and 17, opposite sides of the second window 3 are attached to the frame 1 by magnetic attraction so that the second window 3 can slide along the side edges of the first window 2 against the frame 1 and provide friction to the second window 3.

In this embodiment, the sum of the friction force and the upward tension force of the elastic component 6 on the second window 3 is substantially equal to the gravity of the second window 3, so that the second window 3 can hover at any position in the sliding travel without the need of external force to prevent the second window 3 from sliding down.

As shown in fig. 15, 16, 17 and 19, the window structure includes a magnetic positioning assembly 7, the magnetic positioning assembly 7 includes a plurality of magnets 701 provided on the second window 3, and the plurality of magnets 701 contact with the metal frame 1 and attract the frame 1, so that the second window 3 abuts against the frame 1 under the effect of magnetic force, thereby restricting the second window 3 from being turned outwards by means of magnetic force, and providing friction damping for the second window 3.

For example, the magnetic positioning assembly 7 is provided on the sliding rail 5, so that the sliding rail 5 is magnetically attached against the frame 1, thereby enabling the second window 3 to be attached to the frame 1 and to slide against the frame 1. However, the application is not limited thereto, and the magnetic positioning assembly 7 may also be disposed on the frame 1, and the sliding rail 5 is made of metal, so that the sliding rail 5 can be attached to the frame 1 by magnetic attraction.

Optionally, a plurality of magnets 701 are fixed on the second side plate 5022 of the second rail 502, the plurality of magnets 701 are located outside the guide groove 503 of the first rail 501, and the plurality of magnets 701 are arranged on the second side plate 5022 at intervals along the longitudinal direction of the second window 3 to increase the range of magnetic force, and increase the magnetic force between the second window 3 and the frame 1.

Alternatively, a plurality of magnets 701 are arranged at intervals over the entire longitudinal width of the second window 3 so that the entire side edge of the second window 3 closely fits the frame 1.

Although the window structure may be partially opened by sliding the second window 3 toward the first window 2, space requirements may not be satisfied in some cases, in order to provide a larger window opening space, the first window 2 and the second window 3 may need to be integrally flipped, and thus, when the second window 3 is slid to overlap the first window 2 (as shown in fig. 7), the stacked first window 2 and second window 3 may be integrally flipped by driving the flipping driver 4, thereby opening the entire inner space of the frame 1.

Fig. 8 provides an installation example of the two turnover drivers 4, the two turnover drivers 4 are respectively arranged at two opposite sides of the first window 2, the turnover drivers 4 are gas springs, one ends of the gas springs are hinged with the longitudinal supporting rods 101 of the frame 1, and the other ends of the gas springs are hinged with the first longitudinal rods 202 of the first window 2, so that the gas springs can drive the first window 2 and the second window 3 to turn or reset through expansion and contraction.

Fig. 7 and 8 are schematic views of the window structure in an unopened state, i.e. the piston rod 401 of the gas spring is not extended, the second window 3 is tightly attached to the frame 1, and the first window 2 and the second window 3 are kept in a vertical state.

Fig. 9 and 10 are schematic views of the window structure in a first flipped open state, i.e. the piston rod 401 of the gas spring extends a first length, driving the first window 2 and the second window 3 to flip a first angle relative to the frame 1. For example, the first angle is 30 ° or 45 °.

Fig. 11 and 12 are schematic views of the window structure in a second flipped open state, i.e. the piston rod 401 of the gas spring extends out a second length, and drives the first window 2 and the second window 3 to flip relative to the frame 1 by a second angle, wherein the second length is greater than the first length, and the second angle is greater than the first angle. For example the second angle is 60.

Fig. 13 and 14 are schematic views of the window structure in a third flipped open state, i.e. the piston rod 401 of the gas spring extends a third length, and drives the first window 2 and the second window 3 to flip relative to the frame 1 by a third angle, wherein the third length is greater than the second length, and the third angle is greater than the second angle. For example, the second angle is 90 °.

When the first window 2 and the second window 3 are turned to different positions, the gas spring can keep the first window 2 and the second window 3 at the corresponding positions without worrying about automatic turning and resetting of the first window 2 and the second window 3. The piston rod 401 of the gas spring drives the first window 2 and the second window 3 to reset by retracting.

The gas spring is only an example of the flip actuator 4, and does not limit the scope of the present application, but the flip actuator 4 may be other telescopic driving means.

In order to enable the second window 3 and the first window 2 to remain in a stacked state, the second window 3 is prevented from sliding down relative to the first window 2 during overturning, in some embodiments, as shown in fig. 8, 16 and 20, the window structure of the present application further includes a first locking mechanism 8 for releasably locking the stacked first window 2 and second window 3, the first locking mechanism 8 includes a first lock tongue 801 and a first lock 802 that can be mutually clamped, one of the first lock tongue 801 and the first lock 802 is provided on the first window 2, and the other is provided on the second window 3, and the first lock tongue 801 and the first lock 802 lock the first window 2 and the second window 3 together by clamping to prevent the second window 3 from sliding down accidentally.

In the example of fig. 16 and 20, the first latch 801 is disposed on the first rail 203 below the first window frame, the lower end of the first latch 801 has a first hook 803, the second lock 902 is disposed on the second rail 303 below the second window frame, the first lock 802 has a second hook 804 that can be ejected and retracted, the second hook 804 has a guiding inclined surface toward the first window 2, and when the second window 3 slides up to overlap with the first window 2, the first hook 803 slides down the guiding inclined surface to the lower side of the second hook 804 and is engaged with the second hook 804, thereby locking the first window 2 and the second window 3 together. When unlocking is required, the button 805 on the first lock body 802 is pressed to retract the second hook 804, so that the second hook 804 and the first hook 803 can be released from being clamped, and the second window 3 can be slid downwards to close the window structure.
