Description

[0001] This application is a divisional application of Chinese invention patent application No. 2020100127582, filed on January 7, 2020, entitled "Outward Opening Top-Hung Window Mechanism". Technical Field

[0002] This invention relates to an outward-opening top-hung window device. Background Technology

[0003] Outward-opening top-hung windows are commonly used in the aluminum alloy window industry. When opened, air flows into the room from the side of the window, not directly onto people, resulting in natural ventilation and a more comfortable feeling. It also greatly reduces the possibility of rainwater entering the room. Outward-opening top-hung windows also avoid taking up interior space when the window is open, and avoid interfering with curtains and retractable clothes rods. Top-hung windows are widely used due to their practicality, high security, and excellent ventilation performance.

[0004] When using outward-opening top-hung windows, screens need to be installed to prevent mosquitoes from entering the room. However, due to the constraints of the outward-opening method, there is a conflict between the screen and the window opening handle. The main solutions are as follows: (1) Add a separate invisible screen to the room. Its disadvantage is that the installation cost is high. (2) Add an independent casement screen to the room. Its disadvantage is that it must be equipped with frame and sash hardware, which is costly. Moreover, the screen needs to be opened first every time the window is opened, which is cumbersome and can easily lead to mosquitoes entering the room. It can also interfere with or even damage the indoor window frame. Summary of the Invention

[0031] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention solves the problem of inconvenience in operating the outward-opening top-hung window after the addition of the screen window by using the window opener and the special base. It is simple, practical and beautiful, and has low cost. It is not easy to damage and easy to clean. In addition, the screen window can always block mosquitoes from the outside during the entire operation process, and the insect prevention effect is good; (2) The base also raises the height of the window opener, which can better adapt to the window frame size and ensure that the protruding end of the window opener is horizontally connected to the bottom of the top-hung window sash. At the same time, the window opener can be easily fixed relative to the window frame without damaging the existing interior decoration; (3) Two reinforcing ribs are added inside the base to enhance the biting force of the screws, prevent the window opener from shaking, and ensure that the base is firmly connected to the window frame.

[0032] The design structure of the first wing plate also has the following technical effects: (1) On the one hand, the first wing plate can act as a seal for the window opener, and on the other hand, it can also serve as a track for the screen sash; (2) The top of the first wing plate adopts a staggered structure, and the bottom of the screen sash is equipped with a fourth vertical plate, a fifth vertical plate and a fourth horizontal plate that cooperate with it. In addition to supporting the screen sash and serving as its guide, the first wing plate can also form multiple continuous sealing surfaces with the bottom of the screen sash, enhancing the sealing effect of the bottom of the screen sash and preventing water from entering. At the same time, the second horizontal plate in the staggered structure can also block the contact surface between the window opener and the first vertical plate, preventing water from entering the interior from the protruding end of the window opener and extending the service life of the window opener; (3) The second horizontal plate can support the plastic slider inside the screen sash, ensuring sealing and reducing the collision between aluminum and aluminum.

[0033] The design structure of the second wing plate, the arc plate of the window frame and the bottom of the top-hung window sash has the following technical effects: (1) It can seal the gap formed between the arc plate and the base, preventing dust from entering and making it difficult to clean; (2) The fifth horizontal plate, the seventh vertical plate and the sixth horizontal plate form a convex corner and a concave corner, which can not only enhance the strength of the sash frame, but also form two continuous and perpendicular sealing surfaces with the first sealing strip, improving the sealing effect; (3) The arc plate is not only aesthetically pleasing, but also ensures that the first sealing strip is in close contact with the concave corner, making the space more compact; (4) The ninth horizontal plate can improve the strength of the window frame, and at the same time, it can cover the top of the third screw to prevent it from rusting. The groove it forms can also be fitted with metal reinforcing support plates when assembling at the corner, ensuring the flatness of the assembled profile.

[0034] The pressure strip structure has the following technical effects: (1) It adopts a snap-fit ​​structure, which is simple and easy to install; (2) The bottom of the pressure strip and the lower frame of the top-hung window sash can not only form a continuous sealing surface, but also increase the pressure at the third sealing strip and improve the sealing effect.

Detailed Implementation

[0042] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings:

[0043] like Figure 1 An outward-opening top-hung window mechanism includes a window frame 10 and a top-hung window sash 5 mounted on the window frame 10.

[0044] The mechanism also includes a base 1 installed on the inner side of the bottom of the window frame 10 and a screen sash 4 installed on the base 1; the base 1 is fixedly installed relative to the bottom of the window frame 10.

[0045] The device also includes a hand-cranked window opener 2 mounted on the base 1. The window opener 2 has a chain that is manually operated for extension and retraction. The end of the chain passes through the base 1 and is connected to the bottom of the top-hung window sash 5.

[0046] The base 1 raises the height of the window opener 2, allowing it to better fit the dimensions of the window frame 10. This ensures that the chain of the window opener 2 is horizontally connected to the bottom of the top-hung window sash 5, while also allowing for easy fixing of the window opener 2 relative to the window frame 10 without damaging the existing interior decoration.

[0047] Specifically, such as Figure 2 The base 1 includes a frame with a rectangular cross-section; a first wing plate 1-1 extends upward from the top of the outer side plate of the frame; the bottom of the screen sash 4 cooperates with the first wing plate 1-1.

[0048] The window opener 2 is installed on the top plate of the frame and connected to the frame by the first screw 3. The bottom of the top plate of the frame is provided with an upper reinforcing rib corresponding to the position of the first screw 3. The protruding end of the window opener 2 passes through the first wing plate 1-1 and is connected to the bottom of the screen sash 4 by the second screw 6.

[0049] The outer side panel of the frame is in contact with the inner side panel of the lower frame of the window frame 10 and is connected by a third screw 9 installed from the outside to the inside. The inner side of the outer side panel of the frame is provided with an outer reinforcing rib corresponding to the position of the third screw 9.

[0050] Two reinforcing ribs can enhance the screw's gripping force, prevent the window opener 2 from shaking, and ensure a stable connection between the base 1 and the window frame 10. Furthermore, the first wing plate 1-1 includes a first vertical plate 1-1-1 with its lower end connected to the frame, a first horizontal plate 1-1-2 with its outer end perpendicularly connected to the upper end of the first vertical plate 1-1-1, a second vertical plate 1-1-3 with its lower end perpendicularly connected to the inner end of the first horizontal plate 1-1-2, and a second horizontal plate 1-1-4 with its outer end perpendicularly connected to the upper end of the second vertical plate 1-1-3.

[0051] The bottom of the screen window sash 4 is provided with a fourth vertical plate 4-1 and a fifth vertical plate 4-2 located inside the fourth vertical plate 4-1. A fourth horizontal plate 4-3 extends horizontally forward from the middle of the fifth vertical plate 4-2.

[0052] The second vertical plate 1-1-3 and the second horizontal plate 1-1-4 are located between the fourth vertical plate 4-1 and the fifth vertical plate 4-2. The lower end of the fourth vertical plate 4-1 is in contact with the top of the first horizontal plate 1-1-2. The inner side of the fourth vertical plate 4-1 corresponds to the outer side of the second vertical plate 1-1-3. The outer end of the fourth horizontal plate 4-3 is located inside the inner end of the second horizontal plate 1-1-4.

[0053] The first wing plate 1-1 not only serves to enclose the window opener 2, but also acts as a track for the screen sash 4. The staggered structure, besides supporting and guiding the screen sash 4, also forms multiple continuous sealing surfaces with the bottom of the screen sash 4. The first horizontal plate 1-1-2 provides a platform for the fourth vertical plate 4-1 to sit on the screen sash 4-1, ensuring that the fourth vertical plate 4-1 is flush with the first vertical plate 1-1-1, guaranteeing a tight seal between the outer skin of the screen sash 4 and the inner skin of the window frame. This enhances the sealing effect at the bottom of the screen sash 4, preventing water ingress. Simultaneously, the second horizontal plate 1-1-4 in the staggered structure also blocks the contact surface between the window opener 2 and the first vertical plate 1-1-1, preventing water from entering the interior from the protruding end of the window opener 2 and extending its service life.

[0054] like Figure 3 A first sealing strip 7 is also provided between the upper-hung window sash 5 and the lower frame of the window frame 10.

[0055] A second wing plate 1-2 extends outward from the outer end of the top plate of the frame of the base 1 to achieve a seal between the base 1 and the window frame 10.

[0056] Specifically, the second wing plate 1-2 includes a third horizontal plate 1-2-1 whose inner end is horizontally connected to the outer end of the top plate of the frame and a third vertical plate 1-2-2 whose upper end is vertically connected to the outer end of the third horizontal plate 1-2-1;

[0057] The inner side panel of the lower frame of the window frame 10 is the twelfth vertical plate 10-1 that contacts the frame body. The lower frame also includes a ninth horizontal plate 10-2 whose left end is connected to the upper end of the twelfth vertical plate 10-1, and an arc plate 10-3 whose lower end is connected to the top surface of the middle part of the ninth horizontal plate 10-2. The center of the arc plate 10-3 is located outside the ninth horizontal plate 10-2. The lower frame also includes a first sealing groove 10-4 with an opening facing outward. The middle part of the inner wall panel of the first sealing groove 10-4 is connected to the upper end of the arc plate 10-3.

[0058] The ninth horizontal plate 10-2 not only increases the strength of the window frame 10, but also conceals the top of the third screw 9 to prevent it from rusting. The resulting groove can also accommodate metal reinforcing support plates during corner assembly, ensuring the flatness of the assembled profiles.

[0059] The first sealing strip 7 is installed in the first sealing groove 10-4;

[0060] The top of the third horizontal plate 1-2-1 is flush with the top of the first sealing groove 10-4, and the third vertical plate 1-2-2 is located on the inner side of the upper part of the inner wall of the first sealing groove 10-4.

[0061] The second wing plate 1-2 can seal the gap formed between the arc plate 10-3 and the base 1, preventing dust from entering and making it difficult to clean.

[0062] The bottom of the top-hung window sash 5 is provided with a sixth vertical plate 5-1, and the second screw 6 passes through the sixth vertical plate 5-1 and connects to the outer end of the protruding end of the window opener 2.

[0063] The bottom of the top-hung window sash 5 is also provided with a fifth horizontal plate 5-2 whose inner end is perpendicularly connected to the lower part of the sixth vertical plate 5-1. The fifth horizontal plate 5-2 is located below the second screw 6. The bottom of the top-hung window sash 5 also includes a seventh vertical plate 5-3 whose upper end is perpendicularly connected to the outer end of the fifth horizontal plate 5-2 and a sixth horizontal plate 5-4 whose inner end is perpendicularly connected to the lower end of the seventh vertical plate 5-3.

[0064] The outer side of the first sealing strip 7 is in contact with the convex corner formed by the seventh vertical plate 5-3 and the sixth horizontal plate 5-4.

[0065] The fifth horizontal plate 5-2, the seventh vertical plate 5-3, and the sixth horizontal plate 5-4 form an inside corner and an outside corner, which not only enhances the strength of the fan frame, but also creates two continuous and perpendicular sealing surfaces with the first sealing strip 7, improving the sealing effect. Meanwhile, the arc plate 10-3 is not only aesthetically pleasing, but also ensures a tight contact between the first sealing strip 7 and the outside corner, resulting in a more compact space.

[0066] like Figure 5 The lower frame of the top-hung window sash 5 is provided with a second sealing groove 5-17 with an opening facing inward on the outer side, and a second sealing strip 8 is installed in the second sealing groove 5-17; the lower frame of the window frame 10 is provided with a thirteenth vertical plate 10-5 on the outer side, and the inner side of the second sealing strip 8 is in contact with the outer side of the thirteenth vertical plate 10-5.

[0067] The first sealing strip 7 and the second sealing strip 8 form a sealing cavity, constituting two layers of sealing, which significantly improves the sealing performance when the window is closed, keeping wind and rain out of the window.

[0068] like Figure 4 A third sealing strip 5-15, which is installed by a pressure strip, is provided between the lower frame of the top-hung window sash 5 and the glass plate 5-16;

[0069] The outer top of the lower frame is provided with a first slot plate 5-5 and a second slot plate 5-6 arranged opposite to each other. Both are inverted L-shaped with their horizontal edges at the top and arranged opposite to each other; the first slot plate 5-5 is located outside the second slot plate 5-6.

[0070] The cross-section of the pressure strip is inverted U-shaped;

[0071] The pressure strip includes an inclined plate 5-10 that slopes outward from top to bottom, a tenth vertical plate 5-11 whose lower end is connected to the upper end of the inclined plate 5-10, an eighth horizontal plate 5-12 whose inner end is perpendicularly connected to the upper end of the tenth vertical plate 5-11, a lower protrusion 5-13 located at the bottom of the outer end of the eighth horizontal plate 5-12, and an eleventh vertical plate 5-14 whose lower end is perpendicularly connected to the right end of the eighth horizontal plate 5-12.

[0072] The inner end of the top horizontal edge of the first slot plate 5-5 has a chamfer that matches the inclined plate 5-10. A gap is left between the eighth horizontal plate 5-12 and the top of the first slot plate 5-5 for sealing with glue. The lower protrusion 5-13 is in contact with the top of the first slot plate 5-5.

[0073] The pressure strip also includes an eighth vertical plate 5-7 and a seventh horizontal plate 5-8 located outside the second slot plate 5-6. The inner end of the seventh horizontal plate 5-8 is perpendicularly connected to the upper end of the eighth vertical plate 5-7. The pressure strip also includes a ninth vertical plate 5-9 whose lower end is perpendicularly connected to the outer end of the seventh horizontal plate 5-8.

[0074] The inner side of the ninth vertical plate 5-9 is in contact with the outer end face of the horizontal plate of the second slot plate 5-6.

[0075] The inner side of the top of the pressure strip is in contact with the third sealing strip 5-15.

[0076] The third sealing strip 5-15 is installed via a pressure strip, which is simple in structure and easy to install. The bottom of the pressure strip and the lower frame of the top-hung window sash 5 can not only form a continuous sealing surface, but also increase the pressure at the third sealing strip 5-15, thereby improving the sealing effect.

[0077] This device solves the problem of inconvenient operation of outward-opening top-hung windows after adding a screen by using the window opener 2 and a special base 1. It is simple, practical and beautiful, with low cost, not easy to damage, easy to clean, and the screen sash 4 can keep mosquitoes and insects outside throughout the entire operation, with better insect prevention effect.
