Description

Technical Field

[0001] This invention relates to the field of sliding door and window technology, specifically to an aluminum alloy sliding door and window that can withstand typhoons. Background Technology

[0002] Aluminum alloy sliding doors and windows are widely used in residential, balconies, kitchens, and commercial spaces due to their advantages such as lightweight, high strength, corrosion resistance, and good sealing performance. These doors and windows open and close horizontally on tracks using rollers, without taking up interior space, making them suitable for scenarios with high requirements for lighting and space utilization.

[0003] When using existing aluminum alloy sliding doors and windows, in order to facilitate the disassembly and assembly of aluminum alloy sliding doors and windows, tracks are generally installed on the upper and lower sides of the window frame. Then, the door and window are lifted up so that the groove at the top of the door and window is inserted into the upper track of the window frame. Then, the door and window are released so that the groove at the bottom of the door and window is locked in the lower track of the window frame for sliding. Therefore, there will be sufficient assembly gap between conventional doors and windows and window frame tracks.

[0004] In windy and rainy weather, the latches on the side of the doors and windows are usually rotated to close and lock the two staggered doors and windows. However, in typhoon weather, the connection between the doors and windows and the window frame track will not only sway at different positions, but also cause the conventional latches of the two staggered doors and windows to be damaged and fall off. At the same time, the constantly swaying doors and windows are also prone to vibration and compression of the lower track of the window frame, which will cause deformation of the lower track of the window frame that supports the door and window pulleys. This makes conventional aluminum alloy sliding doors and windows difficult to adapt to typhoon weather. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum alloy sliding door and window that can withstand typhoons, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy sliding door and window that can withstand typhoons, including a window frame embedded in the building wall, an upper track and a lower track respectively provided at the top and bottom of the inner side of the window frame, an inner window and an outer window connected by pulleys on the lower track of the inner side of the window frame, and the inner window and the outer window being closed and locked by a locking assembly;

[0007] The two vertical sides of the inner window and the vertical side of the outer window away from the latch assembly are all embedded with operating mechanisms. The operating mechanisms include notches opened on the front of the vertical sides of the inner and outer windows, and assembly strips fastened by screws are installed in the grooves of the inner and outer windows near the notches.

[0008] The center of the combination strip is provided with a central locking mechanism that locks the inner and outer windows in place to prevent them from being opened. The cooperation between the central locking mechanism and the latch assembly enables the inner and outer windows to be double-locked when closed.

[0009] The upper side of the combination strip is provided with an upper locking mechanism to restrict the top of the inner window and the outer window to the upper track of the window frame, and the lower side of the combination strip is provided with a lower locking mechanism to prevent the bottom of the inner window and the outer window from swaying and to lock them to the lower track of the window frame.

[0010] Preferably, a cover plate with a central hollow section is installed in the recess, and a lever slides inside the cover plate. A push-pull bracket is installed on the side of the lever away from the cover plate, and straight rods are vertically fixed at both ends of the push-pull bracket.

[0011] The upper part of the inner side of the combined strip is provided with a connecting right-angle opening and a guide groove. The right-angle opening is composed of an adjustment port of the vertical section and a self-locking port of the horizontal section. A magnetic block is embedded in the self-locking port of the horizontal section, and stops are symmetrically installed in the guide groove.

[0012] Preferably, the central locking mechanism includes a rack embedded on one side of the lever, a drive gear that meshes with the rack in the inner window near the lock body, and a reserved groove in the middle of the combination bar, with a sleeve and a pad connected in the reserved groove.

[0013] Preferably, a spiral groove is formed on the inner wall of the sleeve, and a protrusion that mates with the spiral groove is fixed on the central shaft of the drive gear;

[0014] A pin is installed at the end of the sleeve that passes through the reserved groove. The outer surface of the pin has a serrated groove. The rotating drive gear drives the protrusion on the central shaft to reciprocate and press the spiral groove, so that the pin of the sleeve can reciprocate and extend along the inner window.

[0015] Preferably, the latch assembly consists of a lock body and a latch hook. The lock body is rotatably connected to the assembly strip on one side of the inner window, and the latch hook is installed on the side of the outer window near the lock body.

[0016] Preferably, a limiting opening is provided on the surface of the outer window near the locking hook, and a locking block is connected inside the limiting opening by a spring.

[0017] Preferably, the upper locking mechanism includes an L-shaped slider that slides in a right-angle opening. The surface of the L-shaped slider has an oblique opening that aligns with the top straight rod of the push-pull frame. The upper side of the L-shaped slider near the oblique opening also has a horizontal cavity, and an upper pull rod is connected inside the horizontal cavity.

[0018] The top of the guide groove has a top pin and a sliding sleeve that slide together, with the top pin inserted into the sliding sleeve.

[0019] Both the bottom end of the top pin and the bottom end of the sliding sleeve are embedded with magnets of the same polarity, so that the bottom ends of the top pin and the bottom ends of the sliding sleeve repel each other. A positioning hole is opened on the upper track surface of the window frame near the sliding sleeve.

[0020] Preferably, the upper pull rod is divided into two disconnected rods by a buffer. The buffer is formed by hinged ends of two sets of inner and outer chain plates, and the adjacent ends of the two disconnected rods are respectively hinged to the middle of the opposite sides of the two sets of inner chain plates.

[0021] Preferably, the lower locking mechanism includes a pull rod that moves up and down with the bottom straight rod of the push-pull frame, and a rack is fixed to the bottom end of the pull rod. A gear plate and a clamp are movably connected inside the combined bar.

[0022] Preferably, the gear plate and the clamp are connected by a traction arm, and the gear plate and the rack mesh for transmission. The bottom of the clamp has a U-shaped structure, and the thickness of the side of the bottom of the clamp gradually decreases from top to bottom.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The typhoon-resistant aluminum alloy sliding door and window, through the operating mechanisms on the inner and outer windows, drives the middle locking mechanism, upper locking mechanism and lower locking mechanism to operate synchronously, which can provide multi-point anti-fall locking and anti-sway protection for the inner window, outer window and window frame. At the same time, through the self-locking characteristic of the upper locking mechanism, the upper locking mechanism in the self-locking state can continuously lock and limit the middle locking mechanism and lower locking mechanism, ensuring that the aluminum alloy sliding door and window has a multi-point stable restriction protection effect in typhoon weather. In addition, the lower locking mechanism can also prevent the lower track of the window frame from deforming under the long-term vibration and pressure of the inner and outer windows, preventing the aluminum alloy sliding door and window from shaking and falling due to typhoon weather.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-3 The present invention provides a technical solution: an aluminum alloy sliding door and window that can withstand typhoons, including a window frame 1 embedded in the building wall, an upper track and a lower track respectively provided at the top and bottom of the inner side of the window frame 1, an inner window 2 and an outer window 3 connected by pulleys on the lower track of the inner side of the window frame 1, and the inner window 2 and the outer window 3 are closed and locked by a locking assembly 4.

[0043] Please see Figures 1-6 , Figure 8 , Figure 9 , Figure 13 and Figure 14 Operating mechanisms 5 are embedded in the two vertical sides of the inner window 2 and the vertical side of the outer window 3 away from the latch assembly 4. The operating mechanism 5 includes a notch 502 opened on the front of the vertical side of the inner window 2 and the outer window 3. A combination strip 501 fastened by screws is installed in the groove of the inner window 2 and the outer window 3 near the notch 502. A cover plate 503 with a hollow center is installed in the notch 502, and a lever 504 slides in the cover plate 503. A push-pull bracket 505 is installed on the side of the lever 504 away from the cover plate 503. Straight rods are vertically fixed at both ends of the push-pull bracket 505.

[0044] The upper part of the inner side of the combination bar 501 is provided with a connecting right-angle opening 5011 and a guide groove 5012. The right-angle opening 5011 is composed of an adjustment port of the vertical section and a self-locking port of the horizontal section. A magnetic block 5013 is embedded in the self-locking port of the horizontal section. A stop block 5014 is symmetrically installed in the guide groove 5012.

[0045] In this embodiment, since there are a total of three sets of operating mechanisms 5 on the two vertical sides of the inner window 2 and the vertical side of the outer window 3 away from the locking assembly 4, in typhoon weather, people need to use the three sets of operating mechanisms 5 to lock the window frame 1, the inner window 2 and the outer window 3 at multiple points. This allows the vertical sides of the inner window 2 and the outer window 3 that are offset to be locked, making it convenient to securely restrict the wider inner window 2 and the outer window 3. It also prevents children from accidentally unlocking all the windows when operating one set of operating mechanisms 5.

[0046] Please see Figure 1 , Figure 4 , Figure 5 and Figure 14The latch assembly 4 consists of a lock body and a lock hook. The lock body is rotatably connected to the combination strip 501 on one side of the inner window 2. The lock hook is installed on the side of the outer window 3 near the lock body. When the lock body is rotated in the forward direction and engages with the lock hook, the inner window 2 and the outer window 3 will be locked and closed. When the lock body is rotated in the reverse direction and disengaged from the lock hook, the inner window 2 and the outer window 3 can be pushed and pulled open and closed.

[0047] Please see Figures 4-8 and Figure 11 The center of the combination bar 501 is provided with a central locking mechanism 6 to lock the inner window 2 and outer window 3 after they are closed to prevent them from being opened. The cooperation between the central locking mechanism 6 and the latch assembly 4 can achieve double closure and locking of the inner window 2 and outer window 3. The central locking mechanism 6 includes a rack 601 embedded on one side of the lever bar 504. The inner window 2 near the lock body is provided with a drive gear 602 that meshes with the rack 601. A reserved groove is provided in the middle of the combination bar 501, and a sleeve 604 and a pad are connected in the reserved groove. The pad can guide the sleeve 604 in the reserved groove, and when the pad is removed from the reserved groove, it is convenient to disassemble and assemble the sleeve 604 in the reserved groove.

[0048] Please see Figures 4-8 as well as Figures 14-16 The inner wall of the sleeve 604 is provided with a spiral groove 605. The central shaft of the drive gear 602 is fixed with a protrusion 603 that mates with the spiral groove 605. The end of the sleeve 604 that passes through the reserved groove is equipped with a pin 606. The outer surface of the pin 606 is provided with a serrated groove. The rotating drive gear 602 drives the protrusion 603 on the central shaft to reciprocate to press the spiral groove 605, so that the pin 606 of the sleeve 604 can reciprocate to extend and retract along the inner window 2.

[0049] A limiting port 301 is provided on the surface of the outer window 3 near the lock hook, and a locking block 303 is connected inside the limiting port 301 by a spring 302.

[0050] In this embodiment, when the operating lever 504 moves up and down, the lever 504 drives the rack 601 to mesh with the drive gear 602. As a result, the drive gear 602 reciprocates by pressing the spiral groove 605 through the protrusion 603 on the central shaft. This causes the sleeve 604 to reciprocate and extend the pin 606 on one side of the pad. The pin 606, which reciprocates and extends along the inner window 2, will move closer to or away from the outer window 3. When the pin 606 is inserted into the limiting port 301 of the outer window 3, the spring 302 inside the limiting port 301 will press the locking block 303 to lock the serrated groove on the outer surface of the pin 606. This ensures that the closed inner window 2 and outer window 3 are locked in position on their respective sides and can share the pressure of the locking assembly 4. Even if the locking assembly 4 is damaged, the inner window 2 and outer window 3 can still be locked.

[0051] Please see Figure 3 , Figure 4 , Figure 6 , Figures 8-10 , Figure 13 and Figure 14 The upper side of the combination bar 501 is provided with an upper locking mechanism 7 to restrict the top of the inner window 2 and the outer window 3 to the upper track of the window frame 1. The upper locking mechanism 7 includes an L-shaped slider 701 that slides in the right angle opening 5011. The surface of the L-shaped slider 701 is provided with a bevel 702 that connects to the top straight rod of the push-pull bracket 505. The upper side of the L-shaped slider 701 near the bevel 702 is also provided with a horizontal cavity, and an upper pull rod 703 is connected in the horizontal cavity.

[0052] The top of the guide groove 5012 has a top pin 706 and a sliding sleeve 707 that slide together. The top pin 706 is inserted into the sliding sleeve 707. The bottom end of the top pin 706 and the bottom end of the sliding sleeve 707 are both embedded with magnets of the same polarity, so that the bottom end of the top pin 706 and the bottom end of the sliding sleeve 707 repel each other. The upper track surface of the window frame 1 near the sliding sleeve 707 has a positioning hole.

[0053] In this embodiment, by operating the lever 504 inside the cover plate 503 upward, the lever 504 drives the push-pull bracket 505 to move upward. As a result, the push-pull bracket 505 presses the inclined opening 702 on the surface of the L-shaped slider 701 through the straight rod at the top, so that the L-shaped slider 701 pushes the upper pull rod 703 upward along the vertical section adjustment opening of the right angle opening 5011. The upward-moving upper pull rod 703 pushes the top pin 706 upward. Since the bottom end of the top pin 706 and the bottom end of the sliding sleeve 707 are both embedded with magnets of the same polarity, when the top pin 706 moves upward, it will synchronously drive the sliding sleeve 707 to move upward and lead out the top of the combination strip 501. When the top of the sliding sleeve 707 abuts against the surface of the upper track of the window frame 1, the sliding sleeve 707 will immediately stop moving upward. At this time, the top pin 706 pushed by the upper pull rod 703 will move upward and lead out from the sliding sleeve 707.

[0054] When the straight rod at the top of the push-pull bracket 505 presses the L-shaped slider 701 against the upper edge of the right-angle opening 5011, the lever 504, which continues to move upward to its limit position, will continue to press the inclined opening 702 on the surface of the L-shaped slider 701 through the straight rod. This causes the L-shaped slider 701 to move laterally into the self-locking opening of the horizontal section of the right-angle opening 5011 and magnetically engage with the magnetic block 5013. At this time, the L-shaped slider 701 is magnetically attracted and self-locked in the right-angle opening 5011 by the magnetic block 5013. Simultaneously, the L-shaped slider 701... The upward-moving pull rod 703 will insert the top pin 706 into the positioning hole of the upper track of the window frame 1, thereby locking the top areas of the inner window 2 and the outer window 3 to the upper track of the window frame 1. Since the locking process of the inner window 2, the outer window 3 and the upper track of the window frame 1 involves the sliding sleeve 707 first pressing against the surface of the upper track of the window frame 1, and then inserting the top pin 706 into the positioning hole, the combination of the top pin 706 and the sliding sleeve 707 can provide longitudinal and lateral support for the inner window 2, the outer window 3 and the window frame 1.

[0055] It should be noted that: due to the assembly gap between the top of the inner window 2 and the outer window 3 and the upper track of the window frame 1, the inner window 2 and the outer window 3 can be repeatedly disassembled and reassembled within the window frame 1. When the inner window 2 and the outer window 3 are closed and locked by the locking assembly 4, the top of the inner window 2 and the outer window 3 will have a swaying gap with the upper track of the window frame 1. In strong winds or even typhoons, the closed inner window 2 and the outer window 3 will also sway. By using the multi-position top pin 706 to be inserted into the positioning hole of the upper track of the window frame 1, the top area of ​​the closed inner window 2 and the outer window 3 can be forced to achieve multi-point support between the upper track of the window frame 1, thereby connecting the top area of ​​the inner window 2 and the outer window 3 with the window frame 1 as a whole to suppress vibration and swaying.

[0056] Please see Figures 8-10 The upper pull rod 703 is divided into two disconnected rods by a buffer. The buffer is formed by two sets of inner chain plates 704 and outer chain plates 705 hinged end to end. The adjacent ends of the two disconnected rods are respectively hinged to the middle of the opposite side of the two sets of inner chain plates 704. When the L-shaped slider 701 abuts against the lower end of the right angle opening 5011, the top of the stop block 5014 abuts against the buffer. At this time, the distance between the two rods connected by the buffer is kept at its farthest. When the L-shaped slider 701 abuts against the upper end of the right angle opening 5011, the top of the stop block 5014 separates from the buffer. At this time, the distance between the two rods connected by the buffer is kept at its closest.

[0057] In this embodiment, when the L-shaped slider 701 pushes the upper pull rod 703 upward, the rod at the lower end of the upper pull rod 703 will simultaneously push the buffer to move upward and squeeze the inner chain plate 704 and the outer chain plate 705 to generate rotation. When the rod at the lower end of the upper pull rod 703 continues to push the buffer to move upward, the two sets of hinged inner chain plates 704 and outer chain plates 705 will gradually fold laterally and abut against the side wall of the guide groove 5012.

[0058] When the top pin 706 is inserted into the positioning hole of the upper track of the window frame 1, even if the top pin 706 is squeezed against the upper track of the window frame 1 and squeezes the upper pull rod 703 in the opposite direction, the lower end of the upper pull rod 703 will be self-locked due to the magnetic attraction limit of the L-shaped slider 701 and the magnetic block 5013. At the same time, the top pin 706 is pressed against the side of the flat folded buffer and the guide groove 5012, so that the top pin 706 has the ability to be compressed and buffered but cannot move down and get out of the positioning hole. Therefore, in typhoon weather, the inner window 2 and the outer window 3, which are blown by the wind, cannot fall out of the window frame 1 because the top pin 706 cannot get out of the positioning hole of the upper track of the window frame 1.

[0059] Conversely, when the lever 504 inside the operating cover 503 moves down, the straight rod at the top of the push-pull bracket 505 will cause the L-shaped slider 701 to disengage from the magnetic block 5013 and move down along the right-angle opening 5011 due to the pressure of the inclined opening 702. Under this operation, the L-shaped slider 701 will pull the upper pull rod 703 down. At this time, the flattened buffer will gradually achieve vertical folding due to longitudinal relaxation, thereby causing the top pin 706 and the sliding sleeve 707 to move down into the combination bar 501, thus facilitating the push-pull movement of the inner window 2 and the outer window 3 between the upper and lower tracks of the window frame 1.

[0060] Please see Figures 3-6 and Figures 11-14 The lower side of the combination bar 501 is provided with a lower locking mechanism 8 to lock the bottom of the inner window 2 and the outer window 3 on the lower track of the window frame 1. The lower locking mechanism 8 includes a pull rod 801 that moves up and down with the bottom straight rod of the push-pull bracket 505. A rack 802 is fixed at the bottom end of the pull rod 801. A gear plate 803 and a clamp 805 are movably connected inside the combination bar 501. The gear plate 803 and the clamp 805 are connected by a traction arm 804, and the gear plate 803 meshes with the rack 802 for transmission. The bottom of the clamp 805 has a U-shaped structure, and the thickness of the side of the bottom of the clamp 805 gradually decreases from top to bottom.

[0061] In this embodiment, when the push-pull bracket 505 is moved upward by the lever 504, the push-pull bracket 505 will pull the pull rod 801 up by the straight rod at the bottom. The lifted pull rod 801 will drive the rack 802 to mesh with the gear plate 803. The rotating gear plate 803 will squeeze the clamp 805 through the traction arm 804, thereby causing the clamp 805 to flip downward and gradually insert the two sides of the bottom of the clamp 805 into the two sides of the lower track of the window frame 1.

[0062] Since the inner window 2 and the outer window 3 move along the lower track of the window frame 1 by means of pulleys installed in the bottom channel, the downward-flipping clamp 805 will block the joint gap between the bottom channel of the inner window 2 and the outer window 3 and the lower track of the window frame 1, preventing the inner window 2 and the outer window 3 from shaking with the window frame 1 during typhoon weather. This can also buffer and protect the lower track of the window frame 1 that supports the inner window 2 and the outer window 3, preventing the lower track of the window frame 1 from deforming under the long-term vibration and pressure of the inner window 2 and the outer window 3. At the same time, the pressure of the clamp 805 between the inner window 2, the outer window 3 and the lower track of the window frame 1 can also drive the pulley to center and correct to the central area of ​​the lower track of the window frame 1, preventing the pulley supporting the movement of the inner window 2 and the outer window 3 from getting stuck in the rolling between the lower track of the window frame 1.

[0063] It should be noted that when the push-pull bracket 505 on one side of the lever 504 drives the L-shaped slider 701 and the upper pull rod 703 through the straight rod at the top, the upward-moving L-shaped slider 701 will magnetically lock with the magnetic block 5013. The push-pull bracket 505 will also synchronously drive the lower pull rod 801 to move upward through the straight rod at the bottom. Furthermore, the upward-moving lever 504 will also drive the drive gear 602 to rotate through the rack 601. Therefore, when the operating mechanism 5 controls the upper locking mechanism 7 to lock the window frame 1, the inner window 2, and the outer window 3, the middle locking mechanism 6 and the lower locking mechanism 8 will also be locked in the same state, ensuring that the middle locking mechanism 6, the upper locking mechanism 7, and the lower locking mechanism 8 have a synchronous locking effect. By utilizing this synchronous locking effect, when the upper locking mechanism 7 is locked, it can prevent the middle locking mechanism 6 and the lower locking mechanism 8 from unlocking prematurely.

[0064] In addition, the magnetic self-locking of the L-shaped slider 701 by the magnetic block 5013 can also restrict the position of the upward-moving lever 504, ensuring that personnel can determine the locking state of the middle locking mechanism 6, the upper locking mechanism 7, and the lower locking mechanism 8 by observing the position of the lever 504 inside the cover plate 503. Since the operating mechanism 5 is embedded on the two vertical sides of the inner window 2 and the vertical side of the outer window 3 away from the latch assembly 4, when the inner window 2 and the outer window 3 are closed, a set of middle locking mechanisms 6 can be used to lock the inner window 2 and the outer window 3 against each other. Then, the three sets of upper locking mechanisms 7 and the three sets of lower locking mechanisms 8 can be used to make the inner window 2, the outer window 3 and the window frame 1 provide multi-point anti-fall locking and anti-sway protection, so that the aluminum alloy sliding door and window has a multi-point stable restriction protection effect during typhoon weather.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
