Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a sliding casement door and window. Background Technology

[0002] With the development of building door and window systems, composite doors and windows that combine casement and sliding functions are favored by the market due to their flexible spatial adaptability. These doors and windows usually include casement door and window sashes that are hinged to the door and window frame and sliding door and window sashes that can slide horizontally, achieving multiple opening modes through the combination of the two.

[0003] Currently, most casement sliding doors and windows on the market use horizontally arranged pulley assemblies as the sliding guide mechanism. This type of structure usually requires at least two parallel horizontal pulleys (such as rollers or bearings) to be installed at the bottom or side of the sliding sash to guide the sliding trajectory. However, each pulley in this traditional pulley guide method requires an independent installation space. The axle width, wheel diameter, and necessary protective shell of multiple parallel pulleys, when stacked, result in a significant increase in the thickness of the door and window sash section, affecting the aesthetics of the building facade and the space utilization rate. Utility Model Content

[0004] In view of the above problems, this utility model provides a sliding casement door and window, which includes: a door and window frame, a casement door and window sash hinged to the door and window frame, and a sliding door and window sash slidably disposed on the door and window frame, and further includes:

[0005] A telescopic track assembly, one side of which is connected to the casement door / window sash, and the other side of which is provided with at least one pulley assembly;

[0006] The sliding door / window sash is provided with a guide rail extending along its direction of movement. A first limiting structure and a second limiting structure are provided at intervals on the guide rail. The pulley assembly is slidably disposed within the guide rail and is located between the first limiting structure and the second limiting structure.

[0007] When the sliding door / window sash moves to the point where the first limiting structure contacts the pulley assembly, the sliding door / window sash continues to move, driving the telescopic track assembly to extend; when the sliding door / window sash moves to the point where the second limiting structure contacts the pulley assembly, the sliding door / window sash continues to move, driving the telescopic track assembly to retract.

[0008] In one possible implementation, the telescopic track assembly includes:

[0009] A base track, which is fixed to the side of the casement door / window sash, and the base track is provided with a first guide cavity;

[0010] A first movable track, which slides on the first guide cavity, and the first movable track is provided with a second guide cavity;

[0011] The second movable track is slidably connected to the second guide cavity, and the pulley assembly is disposed on the second movable track.

[0012] In one possible implementation, the sliding casement door and window further includes an operating mechanism, a transmission conversion mechanism, and a locking actuator. The operating mechanism is connected to the transmission conversion mechanism, and the transmission conversion mechanism is connected to the locking actuator. When the operating mechanism is driven, the locking actuator is driven through the transmission conversion mechanism to achieve locking or unlocking.

[0013] The operating mechanism and the transmission conversion mechanism are disposed on the sliding door and window sash. The locking execution mechanism includes a locking point and a locking seat that cooperate with each other. One of the locking point and the locking seat is connected to the transmission conversion mechanism, and the other of the locking point and the locking seat is fixed to the door and window frame.

[0014] In one possible implementation, the operating mechanism includes an operating input and a lock;

[0015] The transmission conversion mechanism includes a transmission distribution component and a transmission rod;

[0016] The operation input device is connected to the transmission distribution device, and the transmission distribution device is simultaneously connected to the lock and the transmission rod.

[0017] One of the locking point and the locking seat is connected to the transmission rod, and the other of the locking point and the locking seat is fixed to the door and window frame.

[0018] In one possible implementation, the guide rail has vertically extending grooves at both ends, and each groove contains an elastically deformable anti-collision member. The anti-collision member at the first end of the guide rail constitutes the first limiting structure, and the anti-collision member at the second end of the guide rail constitutes the second limiting structure.

[0019] In one possible implementation, the pulley assembly includes a pulley seat and a pulley rotatably connected to the pulley seat, the pulley seat being fixed to the lateral mounting surface of the telescopic track assembly by a fastening unit.

[0020] In one possible implementation, the casement door / window sash is equipped with an anti-misoperation lock, the anti-misoperation lock comprising:

[0021] A housing, the housing being fixed to the casement door / window sash;

[0022] An anti-misoperation contact block is provided, which is slidably disposed on the housing and has a limited position and a non-limited position.

[0023] The locking tongue is slidably disposed on the housing and has a locked position and an unlocked position. The door and window frame is provided with a lock hole for engaging with the locking tongue. When the locking tongue is in the locked position, it engages with the lock hole to lock. When the anti-misoperation contact block is in the limiting position, it prevents the locking tongue from moving from the locked position to the unlocked position. When the anti-misoperation contact block is in the non-limiting position, it releases the obstruction of the locking tongue.

[0024] A first elastic reset element connects the anti-misoperation contact block to the housing. When the anti-misoperation contact block is in a non-limited position, it is automatically reset by the first elastic reset element.

[0025] The second elastic reset element connects the latch and the housing, and the latch is automatically reset when it is in the unlocked position.

[0026] In one possible implementation, the locking tongue is connected to a limiting post, the limiting post having a first diameter segment and a second diameter segment, the first diameter being larger than the second diameter;

[0027] The anti-misoperation contact block is provided with a composite hole, which is composed of a limiting hole area with a first width and a non-limiting hole area with a second width, wherein the second width is greater than the first width, and the limiting hole area and the non-limiting hole area are connected; the limiting post passes through the composite hole;

[0028] When the anti-misoperation contact block is in the limited position, the sidewall of the limited hole area forms mechanical interference with the first diameter segment;

[0029] When the anti-misoperation contact block is in the non-limited position, the first diameter segment moves into the non-limited hole area.

[0030] In one possible implementation, a baffle is provided on the sliding door / window sash, and the baffle is spatially aligned with the anti-misoperation contact block in the horizontal movement direction. When the sliding door / window sash moves to a position that completely overlaps with the casement door / window sash, the baffle contacts and drives the anti-misoperation contact block to move from the limited position to the non-limited position.

[0031] In one possible implementation, the casement door / window sash is equipped with an automatic limiting device, the automatic limiting device comprising:

[0032] A fixed base is installed on the casement door / window sash;

[0033] A movable limiting rod, comprising: an axial sliding section, a radial stop section, and an end limiting section, wherein the movable limiting rod is slidably disposed on the fixed base;

[0034] The third elastic reset component connects the movable limiting rod to the fixed base;

[0035] The sliding door and window sash is provided with a mating hole for cooperating with the terminal limiting part. The movable limiting rod has a limiting state and a releasing state. When the casement door and window sash is in the closed position, the door and window frame contacts and drives the radial stop part, so that the movable limiting rod switches from the limiting state to the releasing state.

[0036] When the movable limit rod is in the limited state, the third elastic reset member naturally extends and the terminal limit part extends into the mating hole, restricting the movement of the sliding door sash relative to the casement door sash;

[0037] When the movable limit rod is in the released state, the third elastic reset member is compressed and contracts, and the terminal limit part disengages from the mating hole.

[0038] The above-described one or more technical solutions in the embodiments of this application have at least one or more of the following technical effects:

[0039] This utility model provides a sliding casement door and window, in which a telescopic track assembly is connected to the casement door and window sash on one side and a pulley assembly is provided on the other side. By replacing the traditional parallel horizontal pulleys with the telescopic track assembly, less space is occupied in the thickness direction of the door and window, significantly reducing the overall thickness requirement of the door and window and achieving a thinner door and window structure. In addition, the first and second limiting structures set at both ends of the guide track precisely constrain the sliding stroke of the pulley assembly, so that the same set of telescopic track assembly can be adapted to different sizes of door and window sashes by adjusting the distance between the two limiting structures, solving the problem of fixed track length and incompatibility. This application not only eliminates the space waste of traditional horizontal pulley groups to achieve thickness optimization, but also breaks through the bottleneck of standardized production through the cooperation of the first limiting structure, the second limiting structure and the pulley assembly, simultaneously achieving the technical effects of structural thinning and standardized production.

Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0063] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0064] The overall concept of the technical solution provided by this utility model is as follows:

[0065] Please see Figures 1 to 19 Sliding and casement doors and windows include:

[0066] The window / door frame 100, a casement window / door sash 200 hinged to the window / door frame 100, and a sliding window / door sash 300 slidably mounted on the window / door frame 100; wherein, the window / door frame 100 serves as the frame structure of the entire window / door, providing support and fixation; the casement window / door sash 200 is hinged to the window / door frame 100 to achieve the casement function, and the casement window / door sash 200 can be connected to the window / door frame 100 via hinges, and the casement window / door sash 200 can rotate around the hinges to open or close; the sliding window / door sash 300 is slidably mounted on the window / door frame 100 to achieve the sliding function. This sliding casement / door window / door also includes:

[0067] A telescopic track assembly 201 is provided, one side of which is connected to the casement door / window sash 200, and the other side of which is provided with at least one pulley assembly 240. One side of the telescopic track assembly 201 can be fixed to the casement door / window sash 200 by means of screws, hinges or clips, so as to ensure that it can move with the casement door / window sash 200. The other side of the telescopic track assembly 201 is designed with at least one pulley assembly 240, which is used to slide within the guide rail 310 to reduce friction and ensure smooth sliding.

[0068] Understandably, the telescopic track assembly 201 is generally composed of multiple nested tracks, typically including an outer track and an inner track. The outer track, as the outermost layer, is usually fixed to the casement door / window sash 200 or the door / window frame 100, providing basic support and guidance. The inner track is usually nested inside the outer track and can slide within the outer track to achieve the telescopic function. With multiple nested tracks, the telescopic track assembly 201 occupies minimal space in the retracted state, effectively reducing the overall thickness and space occupied by the door / window.

[0069] The sliding door / window sash 300 is provided with a guide rail 310 extending along its direction of movement. A first limiting structure 311 and a second limiting structure 312 are spaced apart on the guide rail 310. A pulley assembly 240 is slidably disposed within the guide rail 310 and is located between the first limiting structure 311 and the second limiting structure 312. The guide rail 310 is used to support the pulley assembly 240, ensuring the stability and accuracy of the sliding door / window sash 300 during the sliding process. The first limiting structure 311 and the second limiting structure 312 are used to limit the sliding range of the pulley assembly 240, thereby controlling the sliding range of the sliding door / window sash 300 and ensuring that it moves within a predetermined range.

[0070] When the sliding door / window sash 300 begins to move, the pulley assembly 240 within the guide rail 310 slides accordingly. When the sliding door / window sash 300 moves to the point where the first limiting structure 311 contacts the pulley assembly 240, the continued movement of the sliding door / window sash 300 drives the telescopic rail assembly 201 to extend. When the sliding door / window sash 300 moves to the point where the second limiting structure 312 contacts the pulley assembly 240, the continued movement of the sliding door / window sash 300 drives the telescopic rail assembly 201 to retract. More specifically, the distance between the first limiting structure 311 and the second limiting structure 312 is related to the width of the door / window sash. For example, a wider door / window sash requires a longer sliding distance, so the distance between the first limiting structure 311 and the second limiting structure 312 is longer to ensure that the sliding door / window sash 300 can be fully opened. Generally, the distance between the first limiting structure 311 and the second limiting structure 312 should be set so that the sliding door / window sash 300 can be fully opened. When manufacturing the sliding door and window sash 300, a blocking structure or a hole for installing the blocking structure can be pre-installed in the guide rail 310. This allows sliding door and window sashes 300 of different sizes to use the same set of base rail 210 and telescopic rail assembly 201 during door and window installation, making them more versatile.

[0071] By replacing the traditional parallel horizontal pulleys with the telescopic track assembly 201, less space is required in the thickness direction of the door and window, significantly reducing the overall thickness requirement of the door and window and achieving a thinner door and window structure. In addition, the first limiting structure 311 and the second limiting structure 312 set at both ends of the guide track 310 precisely constrain the sliding stroke of the pulley assembly 240, so that the same set of telescopic track assembly 201 can be adapted to different sizes of door and window sashes by adjusting the distance between the two limiting structures, solving the problem of fixed track length and incompatibility. This application not only eliminates the space waste of traditional horizontal pulley groups to achieve thickness optimization, but also breaks through the bottleneck of standardized production through the cooperation of the first limiting structure 311, the second limiting structure 312 and the pulley assembly 240, simultaneously achieving the technical effects of structural thinning and standardized production.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0073] Please see Figures 1 to 3 The telescopic track assembly 201 includes:

[0074] The base track 210 is fixed to the side of the casement door / window sash 200. The base track 210 is provided with a first guide cavity 211. Specifically, the base track 210 can be installed on the side facing the sliding door / window sash 300. The base track 210 is provided with a first guide cavity 211 inside, which is used to accommodate the telescopic track assembly 201 and provide it with sliding guidance.

[0075] The first movable track 220 is slidably connected to the first guide cavity 211, and the first movable track 220 is provided with the second guide cavity 221; the main function of the first movable track 220 is to provide primary sliding guidance and to provide support and guidance for the second movable track 230.

[0076] The second movable track 230 is slidably connected to the second guide cavity 221, and the pulley assembly 240 is disposed on the second movable track 230. The main function of the second movable track 230 is to support the pulley assembly 240 and provide secondary sliding guidance.

[0077] When the sliding door / window sash 300 is fully open, such as Figure 18 As shown, the first movable track 220 and the second movable track 230 are both located within the first guide cavity 211 of the base track 210, and the pulley assembly 240 is located at the starting position of the guide track 310. When the sliding door / window sash 300 begins to move, the first limiting member pushes the pulley assembly 240, thereby causing the second movable track 230 to slide within the second guide cavity 221 of the first movable track 220. After the second movable track 230 has completed its travel, it drives the first movable track 220 to slide within the first guide cavity 211 of the base track 210 until the first movable track 220 has completed its travel. Figure 1As shown, the sliding door / window sash 300 is in a fully closed state. When the user pushes the sliding door / window sash 300 in the opposite direction, the second limiting member pushes the pulley assembly 240 in the opposite direction, causing the second movable track 230 and the first movable track 220 to slide in reverse sequentially, returning to the initial fully open state. Through the coordinated work of the double-layer movable tracks and the pulley assembly 240, the sliding casement door / window achieves a smooth sliding from fully open to fully closed. This design not only improves the comfort of using the door / window but also enhances its structural stability and safety.

[0078] Please see Figure 1 , Figure 8 and Figure 9 The sliding casement door and window also includes an operating mechanism 400, a transmission conversion mechanism 500, and a locking actuator 600. The operating mechanism 400 is connected to the transmission conversion mechanism 500, and the transmission conversion mechanism 500 is connected to the locking actuator 600. When the operating mechanism 400 is driven, the locking actuator 600 is driven through the transmission conversion mechanism 500 to achieve locking or unlocking. The operating mechanism 400 can be a handle, knob, or latch, etc., and the transmission conversion mechanism 500 can be a transmission rod 520, gear, or rack, etc. The transmission conversion mechanism 500 is used to convert the linear motion, rotational motion, or other forms of motion of the operating mechanism 400 into the motion of the locking actuator 600.

[0079] The operating mechanism 400 and the transmission conversion mechanism 500 are mounted on the sliding door / window sash 300. The locking actuator 600 includes a locking point 610 and a locking seat 620 that cooperate with each other. One of the locking point 610 and the locking seat 620 is connected to the transmission conversion mechanism 500, and the other of the locking point 610 and the locking seat 620 is fixed to the door / window frame 100. For example, the locking seat 620 is connected to the transmission conversion mechanism 500 and moves with it. The locking point 610 is fixed to the door / window frame 100. As a mating part of the locking point 610, the locking seat 620 provides a channel for the locking point 610 to be inserted and a support point for locking. The locking point 610 is inserted into or disengaged from the locking seat 620 to achieve locking or unlocking.

[0080] Specifically, the user issues a locking command through the operating mechanism 400. The action of the operating mechanism 400 is transmitted through the transmission conversion mechanism 500, driving the locking point 610 or the lock seat 620 in the locking actuator 600 to move. The locking point 610 and the lock seat 620 cooperate with each other, with the locking point 610 inserting into the lock seat 620 or the lock seat 620 wrapping around the locking point 610, thus achieving the locked state of the door and window. Conversely, the user issues an unlocking command through the operating mechanism 400. The action of the operating mechanism 400 is transmitted through the transmission conversion mechanism 500, driving the locking point 610 or the lock seat 620 in the locking actuator 600 to move in the opposite direction. The locking point 610 and the lock seat 620 separate, and the door and window return to the sliding state.

[0081] Please see Figure 8The operating mechanism 400 includes an operating input 410 and a lock 420. The operating mechanism 400 is a component that is directly operated by the user, such as a handle, latch, knob, or button, used to issue locking or unlocking commands. The lock 420 can be a mechanical lock (such as a spring lock, gear lock, or hook lock) or an electronic lock (such as an electromagnetic lock or motor lock). The lock 420 is used to perform locking or unlocking actions to ensure that doors and windows cannot be illegally opened when locked.

[0082] The transmission conversion mechanism 500 includes a transmission distribution component 510 and a transmission rod 520;

[0083] The operation input unit 410 is connected to the transmission distribution unit 510, and the transmission distribution unit 510 is simultaneously connected to the lock 420 and the transmission rod 520;

[0084] One of the locking point 610 and the lock seat 620 is connected to the transmission rod 520, and the other of the locking point 610 and the lock seat 620 is fixed to the door and window frame 100;

[0085] The transmission distribution component 510 is used to distribute the linear or rotary motion of the operation input component 410 to the lock 420 and the transmission rod 520. For example, the transmission distribution component 510 can be a T-shaped transmission component, which is shaped like the letter "T" and can distribute the input motion to multiple output ends, such as simultaneously driving the lock 420 and the transmission rod 520. The transmission rod 520 transmits the motion of the transmission distribution component 510 to the locking actuator 600, realizing the movement of the locking point 610 or the lock seat 620. The transmission rod 520 is usually a rigid rod to ensure the linearity and stability of the motion transmission. Through the coordinated work of the operation mechanism 400, the transmission conversion mechanism 500 and the locking actuator 600, the push-pull casement door and window achieves a safe and reliable locking function.

[0086] Please see Figure 7 The guide rail 310 has vertically extending grooves 313 at both ends, and each groove 313 contains an elastically deformable anti-collision member 314. The anti-collision member 314 at the first end of the guide rail 310 constitutes a first limiting structure 311, and the anti-collision member 314 at the second end of the guide rail 310 constitutes a second limiting structure 312. The design of the anti-collision member 314 effectively prevents damage to the pulley assembly 240 caused by collisions during sliding, thereby improving the service life of the doors and windows. The anti-collision member 314 can be made of commonly used high-elasticity materials such as rubber, silicone, or high-strength plastic, which can effectively absorb collision energy and play a buffering role.

[0087] Please see Figure 3The pulley assembly 240 includes a pulley seat 241 and a pulley 242 rotatably connected to the pulley seat 241. The pulley seat 241 is fixed to the lateral mounting surface of the telescopic track assembly 201 by a fastening unit 243. The pulley seat 241, serving as a support and fixing component for the pulley 242, is typically made of high-strength metal or high-strength plastic to ensure sufficient strength and durability. The pulley 242 contacts and rolls on the guide rail 310, reducing friction during the sliding process of the door / window sash. The pulley 242 is mounted on the pulley seat 241 via a rotatable connection, allowing it to rotate freely. The fastening unit 243 securely fixes the pulley seat 241 to the lateral mounting surface of the telescopic track assembly 201, ensuring that the pulley assembly 240 will not loosen or fall off during sliding. The fastening unit 243 can be a screw, bolt, clip, or other mechanical fastening device. Typically, each sliding door / window sash 300 can be equipped with multiple pulley assemblies 240 to evenly distribute the load during the sliding process and ensure smooth sliding.

[0088] Please see Figure 1 , 10 to Figure 13 The casement door / window sash 200 is equipped with an anti-misoperation lock 700, which includes:

[0089] The housing 710 is fixed to the casement door / window sash 200. The housing 710 serves as the base for the anti-misoperation lock 700, is fixed to the casement door / window sash 200, and provides installation and support for other components. The housing 710 is typically fixed to a suitable position on the casement door / window sash 200 by means of screws, bolts or other fasteners.

[0090] An anti-misoperation contact 720 is slidably mounted on the housing 710. The anti-misoperation contact 720 has a limited position and a non-limited position. The anti-misoperation contact 720 is used to prevent the bolt 730 from being moved without authorization, thereby preventing misoperation. The anti-misoperation contact 720 is slidably mounted on the housing 710 and has two states: a limited position and a non-limited position. When in the limited position, the anti-misoperation contact 720 blocks the movement of the bolt 730, preventing it from unlocking from the locked position. When in the non-limited position, the anti-misoperation contact 720 releases the obstruction of the bolt 730, allowing the bolt 730 to move.

[0091] A locking tongue 730 is slidably mounted on the housing 710. The locking tongue 730 has a locked position and an unlocked position. The door / window frame 100 is provided with a lock hole 110 for engaging with the locking tongue 730. When the locking tongue 730 is in the locked position, it engages with the lock hole 110 to lock. When the anti-misoperation contact block 720 is in the limit position, it prevents the locking tongue 730 from moving from the locked position to the unlocked position. When the anti-misoperation contact block 720 is in the non-limit position, it releases the obstruction of the locking tongue 730. Please refer to [link to relevant documentation]. Figure 13 The latch 730 is used to cooperate with the lock hole 110 on the door and window frame 100 to lock and unlock the door and window. It has two states: locked position and unlocked position. When it is in the locked position, the latch 730 is inserted into the lock hole 110 of the door and window frame 100 to lock the door and window; when it is in the unlocked position, the latch 730 is withdrawn from the lock hole 110 to unlock the door and window.

[0092] The first elastic reset member 740 is connected to the anti-misoperation contact 720 and the housing 710. When the anti-misoperation contact 720 is in a non-limited position, it is automatically reset by the first elastic reset member 740.

[0093] The second elastic reset member 750 connects the locking tongue 730 and the housing 710. When the locking tongue 730 is in the unlocked position, it is automatically reset by the second elastic reset member 750.

[0094] The first elastic reset member 740 and the second elastic reset member 750 are typically made of springs or other elastic materials.

[0095] Specifically, when the casement door / window is locked, the latch 730 is in the locked position and inserted into the lock hole 110 of the door / window frame 100, thus locking the door / window frame 100. The anti-misoperation contact block 720 is in the limit position, preventing the latch 730 from moving to the unlock position and preventing accidental unlocking of the door / window. When it is necessary to unlock the casement door / window, the user needs to first operate the anti-misoperation contact block 720, moving it from the limit position to the non-limit position to release the obstruction of the latch 730. After the anti-misoperation contact block 720 is released, the user can operate the latch 730, moving it from the locked position to the unlock position to unlock the door / window. After the user completes the unlocking operation, the first elastic reset member 740 automatically resets the anti-misoperation contact block 720 to the limit position, restoring its obstruction of the latch 730. After the user completes the opening or closing operation, the second elastic reset member 750 automatically resets the latch 730 to the locked position, ensuring that the door / window is locked again.

[0096] Understandably, the sliding door / window sash 300 has an initial position and an overlapping position within the door / window frame 100, such as... Figure 1 As shown, the sliding door / window sash 300 is located in its original locked position within the door / window frame 100. In this position, the sliding door / window sash 300 performs basic closing and locking functions, ensuring that the door / window can be safely closed and locked when not in use. When the user pushes the sliding door / window sash 300, causing it to slide from its original locked position within the door / window frame 100, the sliding door / window sash 300 gradually overlaps with the casement door / window sash 200, forming a compound opening mode, such as... Figure 18As shown, the sliding door / window sash 300 eventually slides to the overlapping position on the casement door / window sash 200, completely overlapping with it. When the sliding door / window sash 300 is in the overlapping position, the casement door / window sash 200 can open outwards via hinges and / or latches, simultaneously moving the sliding door / window sash 300 along with it. Figure 19 As shown, this composite opening mode provides a larger ventilation and lighting area, and users can choose different opening methods according to their needs. When the sliding door / window sash 300 is not in the overlapping position, the anti-misoperation contact block 720 is always in the limited position, blocking the movement of the latch 730 and preventing the casement door / window from being opened accidentally. Only when the sliding door / window sash 300 slides to the overlapping position can the anti-misoperation contact block 720 be operated to change it from the limited position to the non-limited position, releasing the obstruction of the latch 730. Through the design of the composite opening mode and the anti-misoperation lock 700, the sliding casement door / window achieves flexible spatial adaptability and high security.

[0097] Please see Figures 10 to 12 The locking tongue 730 is connected to the limiting post 760, which has a first diameter section 761 and a second diameter section 762, with the first diameter being larger than the second diameter.

[0098] The anti-misoperation contact block 720 is provided with a composite hole 721, which is composed of a limiting hole area 721a with a first width and a non-limiting hole area 721b with a second width, wherein the second width is greater than the first width, and the limiting hole area 721a and the non-limiting hole area 721b are connected; the limiting post 760 passes through the composite hole 721.

[0099] When the anti-misoperation contact block 720 is in the limit position, the sidewall of the limit hole area 721a forms mechanical interference with the first diameter segment 761;

[0100] When the anti-misoperation contact block 720 is in the non-limited position, the first diameter segment 761 moves into the non-limited hole area 721b.

[0101] Specifically, the first diameter segment 761 has a larger diameter, used to mechanically interfere with the limiting hole area 721a of the anti-misoperation contact block 720, restricting the movement of the locking tongue 730; the second diameter segment 762 has a smaller diameter, allowing the limiting post 760 to move freely within the non-limiting hole area 721b; for example... Figure 11 As shown, when the anti-misoperation contact block 720 is in the limit position, the sidewall of the limit hole area 721a forms mechanical interference with the first diameter segment 761 of the limit post 760. Due to the mechanical interference, the limit post 760 cannot move, and the locking tongue 730 is restricted to the locked position and cannot be unlocked. In this state, the locking tongue 730 is locked to prevent accidental unlocking of the door and window; please refer to Figure 12When unlocking is required, the user needs to operate the anti-misoperation contact 720 first, moving it from the limited position to the non-limited position. When the anti-misoperation contact 720 moves to the non-limited position, the first diameter segment 761 of the limiting post 760 moves from the limiting hole area 721a to the non-limiting hole area 721b. Since the width of the non-limiting hole area 721b is greater than the first diameter segment 761, the mechanical interference is released, and the limiting post 760 can move freely. After the mechanical interference is released, the user can operate the locking tongue 730, moving it from the locked position to the unlocked position to unlock the casement door / window sash 200.

[0102] Please see Figure 6 and Figure 7 A baffle 320 is provided on the sliding door / window sash 300. The baffle 320 and the anti-misoperation contact block 720 are spatially aligned in the horizontal movement direction. When the sliding door / window sash 300 moves to a position that completely overlaps with the casement door / window sash 200, the baffle 320 contacts and drives the anti-misoperation contact block 720 to move from the limit position to the non-limit position.

[0103] Specifically, in the initial state, the sliding door / window sash 300 is located in its original locked position or not fully overlapped position within the door / window frame 100. The anti-misoperation contact block 720 is in a limited position, blocking the movement of the latch 730 and preventing the door / window from unlocking. The baffle 320 does not contact the anti-misoperation contact block 720 and does not affect the state of the anti-misoperation contact block 720. When the user pushes the sliding door / window sash 300, moving it from its original locked position towards the hinged door / window sash 200, the sliding door / window sash 300 and the hinged door / window sash 200 gradually overlap. When the sliding door / window sash 300 moves to overlap with the hinged door / window sash 200... When fully overlapped, the baffle 320 and the anti-misoperation contact block 720 are spatially aligned in the horizontal movement direction. The baffle 320 contacts the anti-misoperation contact block 720 and pushes it from the limited position to the non-limited position, releasing the obstruction of the latch 730. After the anti-misoperation contact block 720 is released, the user can operate the latch 730 to move it from the locked position to the unlocked position, thus unlocking the door and window. The casement door and window sash 200 can be opened outwards via hinges and / or latches, simultaneously moving the sliding door and window sash 300 together, forming a compound opening mode. The cooperation between the baffle 320 and the anti-misoperation contact block 720 enables the automatic unlocking function when the sliding door and window sash 300 moves to a specific position, reducing the user's operation steps and improving ease of use.

[0104] Please see Figure 1 , Figures 14 to 18 The casement door / window sash 200 is equipped with an automatic limit device 800, which includes:

[0105] The fixed base 810 is installed on the casement door / window sash 200. The fixed base 810 serves as the mounting base for the automatic limit device 800. It is fixed on the casement door / window sash 200 to provide support and guidance for the movable limit rod 820. The fixed base 810 is usually fixed in a suitable position on the casement door / window sash 200 by screws, bolts or other fasteners.

[0106] The movable limiting rod 820 includes an axial sliding section 821, a radial stop section 822, and a terminal limiting section 823. The movable limiting rod 820 is slidably disposed on the fixed base 810. The axial sliding section 821 allows the movable limiting rod 820 to slide axially on the fixed base 810. The radial stop section 822 contacts the door / window frame 100 to sense the closed state of the door / window and triggers the switching of the limiting state. The terminal limiting section 823 engages with the mating hole 330 on the sliding door / window sash 300 to restrict its movement relative to the casement door / window sash 200.

[0107] The third elastic reset element 824 connects the movable limit rod 820 and the fixed base 810. The third elastic reset element 824 is used to provide elastic force so that the movable limit rod 820 automatically switches between the limited state and the released state. The third elastic reset element 824 can usually be made of spring or other elastic material.

[0108] The sliding door / window sash 300 is provided with a mating hole 330 for cooperating with the terminal limiting part 823. The movable limiting rod 820 has a limiting state and a releasing state. When the casement door / window sash 200 is in the closed position, the door / window frame 100 contacts and drives the radial stop part 822, so that the movable limiting rod 820 switches from the limiting state to the releasing state.

[0109] When the movable limit rod 820 is in the limited state, the third elastic reset member 824 naturally extends, and the terminal limit part 823 extends into the mating hole 330, restricting the movement of the sliding door and window sash 300 relative to the casement door and window sash 200.

[0110] When the movable limit rod 820 is in the released state, the third elastic reset member 824 is compressed and retracts, and the terminal limit part 823 disengages from the mating hole 330.

[0111] Specifically, when the casement door / window sash 200 is closed, the door / window frame 100 contacts and pushes the radial stop portion 822 of the movable limit rod 820. The radial stop portion 822 is pushed, causing the movable limit rod 820 to switch from a limited state to a released state. The third elastic reset member 824 is compressed and contracts, and the terminal limit portion 823 of the movable limit rod 820 disengages from the mating hole 330, allowing the sliding door / window sash 300 to move freely. The user can freely push or pull the sliding door / window sash 300 because the terminal limit portion 823 has disengaged from the mating hole 330 and its movement is not restricted. When the casement door / window sash 200 is opened, the door / window frame 100 moves away from the radial stop portion 822 and no longer pushes the movable limit rod 820. The third elastic reset member 824 naturally extends, and the terminal limit portion 823 of the movable limit rod 820 extends into the mating hole 330, switching to the limited state. Figure 17 As shown, the terminal limiting part 823 extends into the mating hole 330 to restrict the movement of the sliding door / window sash 300 relative to the casement door / window sash 200, preventing accidental sliding. The automatic limiting device 800 can automatically switch the limiting state according to the state of the casement door / window sash 200, without requiring manual operation by the user, thus improving the convenience of use.
