Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a folding skylight and system. Background Technology

[0002] Due to the harsh wind and rain environment at the top of super high-rise buildings in coastal areas, in order to ensure the water tightness and air tightness of the building, roof skylights are generally not equipped with operable sashes. Even if they are, they are usually single sashes that open independently. The operable sash protrudes from the skylight surface and the opening angle is quite limited. After opening, the frame obstructs the view inside the room, which does not help to improve comfort.

[0057] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0058] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a folding skylight, comprising:

[0059] Main framework;

[0060] The skylight unit is movably connected to the main frame.

[0061] The skylight unit includes at least one set of window sashes 5, and two window sashes in the at least one set of window sashes 5 are movably connected to each other.

[0062] Multiple sets of locking devices are evenly distributed on the main frame. When two window sashes in at least one set are closed, the locking devices fix the window sashes to the main frame.

[0063] A drive unit is fixedly connected to the main frame. When the drive unit drives at least one set of window sashes 5 in the skylight unit to move on the main frame, two window sashes in the at least one set of window sashes 5 open or close.

[0064] In this embodiment, the main frame is a frame with a rectangular opening, which provides support for the skylight unit and other components. When installing the skylight, the skylight unit is first movably connected to the main frame, and then the main frame is fixedly connected to the roof to achieve the overall installation of the skylight and improve the installation efficiency and accuracy of the skylight.

[0065] The skylight unit is disposed on the main frame, and its size and shape are consistent with the rectangular opening of the main frame to close the rectangular opening. The skylight unit includes at least one set of window sash groups 5, and each set of window sash groups includes two window sashes of the same size and shape. The two window sashes are arranged side by side and are movably connected to each other to facilitate the opening and closing of the window sashes. When the skylight unit is provided with multiple sets of window sash groups, the multiple sets of window sash groups are arranged sequentially on the main frame, and adjacent sets of window sash groups are movably connected. In practical applications, the number of window sash groups can be set according to actual needs.

[0066] Multiple sets of locking devices are evenly distributed on both sides of the main frame. When at least one set of window sashes 5 is closed, the locking devices fix the two sides of the two window sashes in the window sash set to the two sides of the main frame to ensure that the window sashes can be stably attached to the main frame when the skylight is closed, thus ensuring the stability of the skylight unit.

[0067] The drive unit, fixed to the main frame, drives at least one set of window sashes 5 in the skylight unit to move on the main frame, and further drives two window sashes in the at least one set of window sashes 5 to move, so as to open or close two window sashes in the at least one set of window sashes 5, and realize the overall opening or closing of the skylight.

[0068] Furthermore, the main framework will be described as follows: Figures 4 to 5 As shown, the main frame includes: a first support 11, a second support 12, a third support 13, and a fourth support 14;

[0069] The first bracket 11, the second bracket 12, the third bracket 13 and the fourth bracket 14 are fixedly connected in sequence to form a main frame with a rectangular opening.

[0070] In this embodiment, the first support 11, the second support 12, the third support 13, and the fourth support 14 can be configured as three-dimensional support columns or as support plates. The first support 11 and the third support 13 are arranged parallel to each other. The second support 12 and the fourth support 14 are arranged parallel to each other at the parallel gap formed by the first support 11 and the third support 13. The four supports are sequentially fixedly connected, with the two ends of the second support 12 perpendicular to the first support 11 and the third support 13, respectively, and the two ends of the fourth support 14 perpendicular to the first support 11 and the third support 13, respectively, thus forming a main frame with a rectangular opening. The fixed connection can be welding or screwing. Of course, the first support 11, the second support 12, the third support 13, and the fourth support 14 forming the main frame can also be integrally formed.

[0071] In an optional embodiment of the present invention, such as Figures 1 to 2 As shown, a protective cover is also provided on the outside of the main frame. The protective cover can be welded to the main frame or screwed to it. The protective cover strengthens the rigidity of the main frame and also protects the main frame and the drive unit. The protective cover includes: a first protective cover 1 disposed on the outside of the first bracket 11; a second protective cover 2 disposed on the outside of the second bracket 12; a third protective cover 3 disposed on the outside of the third bracket 13; and a fourth protective cover 4 disposed on the outside of the fourth bracket 14. Preferably, the protective cover can be made of alloy steel, but other materials with high rigidity and corrosion resistance can also be used.

[0072] In an optional embodiment of the present invention, the skylight unit further includes: a window frame fixed to a rectangular opening of the main frame; two window sashes in the at least one set of window sash groups 5 are arranged sequentially on the window frame; wherein, one side of the first window sash 51 in the at least one set of window sash groups 5 is movably connected to one side of the window frame by a plurality of hinges 127, and the first window sash 51 and the second window sash 52 in the at least one set of window sash groups 5 are movably connected by a plurality of hinges 127.

[0073] In this embodiment, the window frame and the main frame can be welded together. Waterproof strips are provided on both sides of the fixed connection between the window frame and the main frame to improve the overall waterproof performance of the skylight. The size of the window frame matches the size of the rectangular opening on the main frame, further strengthening the rigidity of the main frame. Preferably, both the main frame and the window frame can be made of alloy steel, but other materials with high rigidity and corrosion resistance are also acceptable.

[0074] Furthermore, such as Figure 2 , Figure 4As shown, at least one set of window sashes 5 in the skylight unit is arranged sequentially along the window frame. When multiple sets of window sashes are provided, adjacent sets of window sashes are movably connected by multiple hinges 127, and the first and second window sashes in each set are also movably connected by multiple hinges 127; preferably, as Figure 14 As shown, the specific position of the hinges between two adjacent window sash groups can be set on the outside or inside of the window sash according to the opening trend of the window sash. When the hinges between two adjacent window sash groups are set on the outside of the window sash, the hinges between the two window sashes in each group should be set on the inside of the window sash. When the hinges between two adjacent window sash groups are set on the inside of the window sash, the hinges between the two window sashes in each group should be set on the outside of the window sash to achieve the folding purpose of the window sash when opening. At the same time, the hinge connection can allow for flexible control of the opening angle of the window sash when opening, thereby increasing the opening area of ​​the window sash and further improving the lighting effect when the window sash is open. Figures 5 to 8 As shown, the maximum opening (folding) angle of two window sashes in the at least one group of window sashes is 90°. At this time, the window sashes in all the window sash groups are folded and attached to one side of the first bracket 11.

[0075] When the at least one set of window sashes 5 are arranged sequentially along the window frame, one side of the first window sash in the first set of the at least one set of window sashes 5 is movably connected to one side of the window frame by multiple hinges 127, achieving folding during the opening or closing of the window sash; when the skylight is open, all window sashes in the window sash set are folded to one side of the window frame (the window sash is close to the first bracket 11 when folded), and one side of the second window sash in the last set of the at least one set of window sashes is away from the other side of the window frame (away from the third bracket 13); when the skylight is closed, one side of the second window sash in the last set of the at least one set of window sashes is fitted against the other side of the window frame (fitted against the third bracket 13); preferably, as Figure 9 , 10 As shown in Figures 1 and 13, the two sides of the hinge 127 are respectively fixed to two adjacent window sashes by screws.

[0076] In an optional embodiment of the present invention, such as Figures 9 to 10As shown, a water guide groove 7 is provided on the side where the first window sash 51 and the second window sash 52 overlap in the at least one set of window sashes 5. When the skylight is closed, the second window sash 51 and the first window sash 52 form a certain overlap relationship through the window sash profile construction. The outer end of one side of the second window sash 52 overlaps on one side of the first window sash 51. At the same time, a water guide groove 7 is provided on the side where the first window sash 51 and the second window sash 52 overlap. When the skylight is closed, it can achieve the purpose of waterproofing with a combination of blocking and drainage, which improves the reliability and durability of the skylight waterproofing and changes the status quo of traditional skylights that rely entirely on sealant for waterproofing. At the same time, a waterproof strip is provided on the outer side of the contact surface between the first window sash 51 and the second window sash 52. After the skylight is closed, the waterproof strip squeezes against each other to play a role in sealing and waterproofing.

[0077] like Figure 2 As shown, in an optional embodiment of the present invention, the main frame further includes: a first load-bearing support 111 vertically disposed at one end of the first support 11; and a second load-bearing support 112 symmetrical to the first load-bearing support 111 and vertically disposed at the other end of the first support 11.
