Description

Technical Field

[0001] This utility model belongs to the field of skylights, and in particular relates to a skylight. Background Technology

[0002] Skylights are an important component of building envelopes, referring to window-like devices installed on the roof or slope of a building. Their history is long, dating back to ancient times when openings were made in roofs for lighting and smoke extraction. In modern architecture, skylights have become increasingly versatile, serving as a key technological means to achieve architectural aesthetics, natural lighting, passive energy conservation, and healthy ventilation.

[0003] Most skylights are operable, with common types including tilt-and-turn and rise-type. Tilt-and-turn windows can rotate around one side of the window frame to open, while rise-type windows can move vertically up and down relative to the bottom frame to meet ventilation and, when necessary, pedestrian passage needs. Because the windows need to open, the window frame structure must allow for appropriate space for movement.

[0004] Window frames are typically composed of multiple bottom frames, each with a drainage groove. During installation, these bottom frames are usually welded together to form a rectangular frame to support the window sash. However, in actual welding, due to the confined space, operators often struggle to achieve thorough and uniform welding, leading to substandard weld quality and subsequent leakage problems at the welded areas. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a skylight to solve the problem that due to the small space for welding operations, operators often find it difficult to achieve full and uniform welding, which easily leads to substandard weld quality and leakage at the welded parts.

[0006] To achieve the above and other related objectives, this utility model provides a skylight, including multiple water troughs, multiple bottom frames, and a sash; the multiple water troughs are welded together to form a first rectangular frame; the multiple bottom frames are welded together to form a second rectangular frame, the second rectangular frame being located within the first rectangular frame and connected to the first rectangular frame; the sash includes a first abutting component and a second abutting component, the first abutting component being used to abut against the side wall of the water trough facing away from the bottom frame, and the second abutting component being used to abut against the bottom frame.

[0007] Optionally, one side wall of the water tank includes a first vertical wall segment, a convex arc wall segment, and an inclined wall segment connected in sequence; the first vertical wall segment is perpendicular to the bottom of the water tank; the convex arc wall segment protrudes into the water tank; the inclined wall segment is tangentially connected to the convex arc wall segment; the first abutting component includes a first sealing strip, which is used to press and abut against the inclined wall segment and / or the convex arc wall segment of the water tank.

[0008] Optionally, a second vertical wall section is provided at the end of the inclined wall section away from the convex arc wall section, which is parallel to the first vertical wall section; the second vertical wall section is used to abut against the first sealing strip.

[0009] Optionally, the first abutting component further includes a first mounting groove disposed on the opening, the opening of which faces the convex arc wall section, the first mounting groove being used to install the first sealing strip; the bottom of the first mounting groove is provided with a receiving groove for accommodating the deformation of the first sealing strip.

[0010] Optionally, the first mounting slot is a T-slot.

[0011] Optionally, the receiving groove is V-shaped, with its opening facing the opening of the first mounting groove; the width of the receiving groove opening is smaller than the width of the T-shaped end of the first mounting groove.

[0012] Optionally, it also includes a hinge located inside the convex arcuate wall section of one of the water tanks, with a first end connected to the bottom frame and a second end connected to the opening fan so that the opening fan can rotate relative to the bottom frame.

[0013] Optionally, a second mounting groove is provided on the hinge, and the second end of the hinge is accommodated in the second mounting groove.

[0014] Optionally, the second abutment component includes a vibration damper disposed on the bottom frame and located at a position corresponding to the opening when the opening is closed, for reducing the impact and vibration when the opening is closed.

[0015] As described above, the skylight of this utility model has at least the following beneficial effects:

[0016] By separating the water tank and the bottom frame, when welding the water tank to form the first rectangular frame (drainage channel), the welder can work more comfortably because the operating space is not obstructed by the bottom frame, ensuring that the weld is full and continuous, thus eliminating the risk of water leakage caused by welding defects at the source.

[0017] Secondly, the design achieves a precise division of functions. The drainage channel is dedicated to water discharge, and its circular waterway efficiently collects and guides rainwater; while the base frame focuses on structural load-bearing, stably transferring the skylight body and external loads to the building structure. This division of labor avoids functional overlap, ensuring a clear and unobstructed drainage path. Ultimately, this "drainage-load-bearing" dual-frame system, combined with the precise sealing of the sash joints, forms a robust waterproof barrier, greatly enhancing the overall reliability, durability, and waterproof performance of the skylight.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

[0025] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0026] Please see Figure 1-3This utility model provides a skylight, including a water trough 1, multiple base frames 2, and a sash 3. The multiple water troughs 1 are welded together to form a first rectangular frame. One of the water troughs 1 has a notch for connecting to an external water pipe to drain water from the first rectangular frame. The multiple base frames 2 are welded together to form a second rectangular frame, which is located within and connected to the first rectangular frame. The second rectangular frame is used to connect to concrete or other materials at the installation location, providing an installation space. The sash 3 includes an abutment portion. When the sash 3 is closed, this abutment portion tightly abuts against the side wall of the water trough 1 facing away from the base frame 2, forming an effective seal and jointly realizing the skylight's sealing and opening functions.

[0027] In this embodiment, by separating the water trough 1 and the base frame 2, the welder can work more freely when welding the water trough 1 to form the first rectangular frame (drainage channel) because the working space is not obstructed by the base frame 2. This ensures a full and continuous weld, eliminating the risk of leakage caused by welding defects at the source. Subsequently, the pre-welded second rectangular frame (load-bearing skeleton) is installed into the drainage frame, simplifying the installation process. Secondly, this design achieves a precise division of functions. The water trough 1 is dedicated to drainage, and its annular waterway can efficiently collect and guide rainwater; while the base frame 2 focuses on structural load-bearing, stably transferring the skylight body and external loads to the building structure. This division of functions avoids functional overlap, making the drainage path clear and unobstructed. Finally, this "drainage-load-bearing" dual-frame system, combined with the precise sealing of the opening sash 3, forms a robust waterproof barrier, greatly improving the overall reliability, durability, and waterproof performance of the skylight.

[0028] One side wall of the water tank 1 includes a first vertical wall section 11, a convex arc wall section 12, and an inclined wall section 13 connected in sequence; the first vertical wall section 11 is set perpendicular to the bottom of the water tank 1; the convex arc wall section 12 protrudes into the water tank 1; and the inclined wall section 13 is tangentially connected to the convex arc wall section 12.

[0029] The first abutting component 31 includes a first sealing strip 311, which is used to press and abut against the inclined wall section 13 and / or the convex arc wall section 12 of the water tank 1. The first sealing strip 311 can be made of elastic material such as rubber, and it is set on the opening 3. The first sealing strip 311 is used to press and abut against the inclined wall section 13 and the convex arc wall section 12 of the water tank, thereby preventing water in the water tank 1 from flowing into the bottom frame 2.

[0030] The inclined wall section 13 has a second vertical wall section 14 disposed parallel to the first vertical wall section 11 at one end away from the convex arc wall section 12; the second vertical wall section 14 is used to abut against the first sealing strip 311. When the skylight is closed, the first sealing strip 311 and the second vertical wall section 14 abut against each other to further ensure the sealing effect.

[0031] The first sealing strip 311 is made of rubber or similar material and has an I-shaped structure. Its small end connects to the opening fan 3, and its large end abuts against the side wall of the water tank 1. The small end of the first sealing strip 311 can be connected to the opening fan 3 by adhesive or other means. In this embodiment, the opening fan 3 is provided with a first mounting groove 312 with its opening facing the convex arc wall section 12. The first mounting groove 312 is used to install the first sealing strip 311. The opening width of the first mounting groove 312 is smaller than the groove width of the first mounting groove 312, so as to limit the first sealing strip 311 on the opening fan 3. Preferably, the first mounting groove 312 is a T-shaped groove.

[0032] The bottom of the first mounting groove 312 is provided with a receiving groove 313 for accommodating the deformation of the first sealing strip 311. The receiving groove 313 can be V-shaped, with its opening facing the groove opening of the first mounting groove 312; the opening width of the receiving groove 313 is smaller than the width of the T-shaped end of the first mounting groove 312.

[0033] In this embodiment, the inclusion of the receiving groove 313 provides a pre-defined space for the deformation of the first sealing strip 311, allowing sufficient and controllable radial deformation. This ensures that the sealing strip always operates within its optimal elastic range, maintaining sufficient and uniform contact pressure with the wall of the water tank 1, thereby significantly improving the static sealing reliability in the closed state. Furthermore, the presence of the receiving groove 313 guides and constrains the deformation of the sealing strip, concentrating the deformation within the groove and avoiding stress concentration and irregular twisting, thus effectively slowing down material aging and extending the service life of the sealing strip. Moreover, it provides better tolerance for machining accuracy and assembly errors of the opening sash 3 and the water tank. The additional deformation space provided by the receiving groove 313 can absorb minor dimensional deviations, ensuring that even with errors, the sealing strip can be smoothly installed and achieve effective sealing, improving the overall yield and reliability of the product.

[0034] The skylight provided in this embodiment also includes a hinge 4, which is located on the inner side of the convex arc wall section 12. The first end of the hinge 4 is fixedly connected to the bottom frame 2 by screws or other structures, and the second end is fixedly connected to the opening sash 3 by screws or other structures, so that the opening sash 3 can rotate relative to the water tank. That is, the skylight provided in this embodiment is a side-opening type.

[0035] The skylight provided in this embodiment can be opened or closed by rotating the opening sash 3 relative to the bottom frame 2 via a motor or manual operation. During rotation, the first sealing strip 311 maintains sliding contact with the convex arc wall section 12 and / or inclined wall section 13 of the water tank 1, forming a continuous dynamic sealing barrier. This design has the following significant advantages:

[0036] Excellent dynamic sealing and waterproof performance: By setting convex arc wall section 12 and inclined wall section 13 that continuously abut against the sealing strip on the rotation path, it is ensured that the opening sash 3 can effectively isolate the rainwater and dust accumulated in the water tank 1 at any opening position, which greatly reduces the risk of rainwater seeping into the hinge 4 area and the room through the rotation gap, and improves the applicability and reliability of the skylight in changeable weather.

[0037] Smooth operation and minimal wear: The curvature center of the convex arc wall section 12 coincides or nearly coincides with the rotation axis of the hinge 4, making the sliding trajectory of the sealing strip on the wall section smooth and unobstructed. This effectively reduces frictional resistance and abnormal wear of the sealing material during rotation, improves the operating feel, and extends the service life of the sealing strip.

[0038] The sash 3 is provided with a second mounting groove 33, and the second end of the hinge 4 is accommodated within the second mounting groove 33. The sidewall and bottom of the second mounting groove 33 abut against the corresponding sidewall of the second end of the hinge 4 to achieve quick and accurate positioning of the hinge 4. Then, the hinge 4 is fixed to the sash 3 using screws or other structures. The second mounting groove 33 allows the force and torque acting on the hinge 4 to be more evenly transmitted to the entire sash 3 structure through the sidewall and bottom of the second mounting groove 33 when the sash rotates or is subjected to wind pressure, rather than being borne solely by the fastening screws. This reduces the shear stress on the screws and enhances the overall strength, stability, and fatigue resistance of the connection.

[0039] The skylight in this embodiment also includes a second sealing strip. A third mounting groove 34 is provided on the sash 3. The third mounting groove 34 has a T-shaped structure, and the second sealing strip has an I-shaped structure made of rubber or similar material. The third mounting groove 34 is used to install the second sealing strip, and the second seal 5 is used to seal the gap between the sash 3 and the glass. During installation, the glass is usually bonded to the sash 3 with silicone sealant. In this embodiment, the second sealing strip prevents the glass and sash 3 from rigidly contacting each other during installation, thus avoiding scratches on the glass and preventing sealant leakage.

[0040] The second abutment component in this embodiment includes a vibration damper 32, which can be a rubber damping pad, or it can have the same structure as the first sealing strip 311 and the second sealing strip. A fourth mounting groove for mounting the vibration damper 32 is provided on the bottom frame. The fourth mounting groove can be a T-shaped groove, and the vibration damper 32 can also be an I-shaped structure. The fourth mounting groove is located at the position corresponding to when the opening fan 3 is closed, and is used to reduce the impact and vibration when the opening fan 3 is closed.

[0041] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
