Description
Technical Field
[0001] This invention belongs to the field of casement window manufacturing technology, specifically relating to a multifunctional sliding support and steering angle control component for outward-opening top-hung windows. Background Technology
[0002] Casement windows are a general term for windows that can be opened and closed by both horizontal and vertical rotation. Functionally, they can be divided into four basic types: outward-opening top-hung, outward-opening bottom-hung, inward-opening top-hung, and inward-opening bottom-hung. However, based on practical application needs, outward-opening top-hung windows and inward-opening bottom-hung windows are the two mainstream casement window types on the market. Among them, outward-opening top-hung windows have two opening methods: one side rotates outwards for casement opening and the bottom rotates outwards for tilting. In practical applications, they are often mistakenly referred to as outward-opening bottom-hung windows. However, according to relevant industry standards, outward-opening top-hung windows with the rotating hinge (usually part of the upper sliding support assembly) at the top are called outward-opening top-hung windows, not outward-opening bottom-hung windows. Inward-opening bottom-hung windows have two opening methods: one side rotates inwards for casement opening and the top rotates inwards for tilting. In practical applications, they are often referred to as inward-opening tilt-and-turn windows.
[0003] like Figure 1 and Figure 2 As shown, taking an outward-opening top-hung window as an example, it includes a window frame 3 and a window sash 1. A handle 2 is installed on one side of the window sash 1 (some handles 2 are also installed on the lower side of the window sash 1). A transmission assembly (not marked in the figure, a conventional structure) connected to the handle 2 is installed on the side of the window sash 1 near the handle 2. An upper sliding support assembly (not marked in the figure) is installed on the upper side of the window sash 1, and the upper sliding support assembly is also connected to the upper side of the window frame 3. A lower sliding support assembly (not marked in the figure, a conventional structure) is installed on the lower side of the window sash 1, and the lower sliding support assembly is also connected to the lower side of the window frame 3. The upper end of the transmission assembly can be connected to the transmission rod in the upper sliding support assembly and achieves a 90° turning transmission function through an elastic band (not marked in the figure, a conventional structure, generally a steel band). The lower end of the transmission assembly can be connected to the transmission rod in the lower sliding support assembly and achieves a 90° turning transmission function through an elastic band, thereby realizing corresponding control of the upper sliding support assembly and / or the lower sliding support assembly. When the handle 2 is rotated, the corresponding outward opening (e.g., Figure 1 As shown), open (as shown) Figure 2 The window sash 1 (shown in the diagram) and locking (not shown in the diagram) functions are generally as follows: when handle 2 is in the downward position (generally defined as handle 2 rotated 0°), the window sash 1 is in the closed state and locked to the window frame 3, i.e., the locked state (not shown in the diagram); when handle 2 is in the horizontal position (generally defined as handle 2 rotated 90°), the window sash 1 is in the unlocked state, at which time the handle side of the window sash 1 can be rotated outward to open, i.e., outward opening (as shown in the diagram). Figure 1 As shown), when handle 2 is in the upward position (generally defined as handle 2 rotated 180°), window sash 1 is in the unlocked state. At this time, the lower side of window sash 1 can be rotated outward to open, i.e., open (as shown). Figure 2 (As shown). The inward-opening tilt-and-turn window (i.e., the inward-opening tilt-and-turn window) has a similar structure and working principle as described above, and will not be repeated here.
[0004] Currently, traditional outward-opening top-hung windows still have the following drawbacks: First, because rotating the handle can only synchronously drive the transmission rods of the upper and lower sliding support components, when the window is closed, it can only achieve a three-sided locking and sealing function (upper side, lower side, and the vertical side where the handle is located), and cannot achieve a locking and sealing function on the other vertical side, i.e., it cannot achieve a four-sided locking and sealing function, so the locking and sealing effect is not ideal. Second, it cannot achieve window opening control functions that only allow the window to be opened and not allowed to be opened (such as hotels using this function for security reasons) or only allow the window to be opened and not allowed to be opened (this function is generally not used, but may be used in special circumstances), as well as the four-sided locking and sealing function under the corresponding function. Furthermore, it cannot achieve this function through the vertical side without a handle and the corresponding turning angle. In practical applications, the vertical side with a handle and the upper and lower sides require the integration of many structures, making it difficult to set up a reasonable structure to achieve this function. Therefore, the lack of a handle is a more effective solution. The vertical side and corresponding turning angle are crucial for achieving this function; third, the sliding support assembly lacks a function to prevent the handle from rotating after it has been rotated to 180° and is open (this function is beneficial for anti-theft), and it also lacks a function that requires the handle to be rotated to 180° to achieve the open function. Alternatively, if these two functions are present, the structure is not reasonable enough, and the control method is not smooth or reliable enough; fourth, the sliding support assembly does not have the function of reliably controlling the window sash opening angle, open angle, and locking state after opening. In practical applications, for safety reasons, such as in hotels, reliable control of the window sash opening angle, open angle, and locking state after opening is of great significance. It can prevent strong winds from closing the window sash and can also prevent accidents involving children. At the same time, the connection structure of the multiple rotating parts in the sliding support assembly is not reasonable enough, which can easily lead to problems such as either smooth opening and closing but poor stability after opening, or good stability after opening but high opening and closing resistance. Summary of the Invention
[0005] The purpose of this invention is to provide a multifunctional sliding support and steering angle control component for outward-opening top-hung windows that can achieve four-sided locking and sealing functions in order to solve the above-mentioned problems.
[0006] The present invention achieves the above objectives through the following technical solutions:
[0007] A multifunctional sliding support and steering angle control assembly for an outward-opening top-hung window includes a window sash connecting rod for connection to the window sash, a horizontal transmission rod for transmission, and a window frame connecting rod for connection to the lower side of the window frame. A handle is installed on one vertical side of the window sash. The window sash connecting rod and the window frame connecting rod are connected by a rotating assembly. The multifunctional sliding support and steering angle control assembly for an outward-opening top-hung window also includes an "L"-shaped steering angle link, an elastic band, a vertical transmission rod, and a lock seat. The window sash connecting rod is "L"-shaped, with its horizontal bar for connection to the lower side of the window sash and its vertical bar for connection to the vertical side of the window sash without a handle. The rotating assembly is installed on the horizontal bar of the window sash connecting rod and connected to the window frame. Between the rods, the "L"-shaped steering angle connecting rod is installed at the steering angle position of the window sash connecting rod. The steering angle position of the "L"-shaped steering angle connecting rod is arc-shaped and has a strip-shaped limiting groove. The limiting groove is "L"-shaped and its steering angle position is arc-shaped. The elastic band is placed in the limiting groove. The two ends of the elastic band are respectively connected to one end of the horizontal transmission rod and one end of the vertical transmission rod. The vertical transmission rod is provided with a lock head. The lock head passes through the corresponding strip-shaped through hole on the vertical rod of the window sash connecting rod and can be connected to the lock seat (the connection here is actually a tight fit between them, with only blocking and limiting functions between them, without a fixed connection structure). The lock seat is installed on the corresponding vertical side of the window frame. The aforementioned lock base and lock head are conventional components in existing technology. Lock bases installed on window frames generally have a protruding blocking part, and lock heads installed on window sashes are generally protruding posts. When the lock head is located at the corresponding position of the blocking part of the lock base, it can be blocked by the blocking part of the lock base, preventing the window sash from being opened. Moreover, the end surface of the blocking part is generally designed as an arc surface or a bevel, which has the function of allowing the lock head to gradually slide into the corresponding position in the middle of the blocking part. In this way, the tight locking function between the window sash and the window frame is achieved, that is, the locking and sealing function of the window sash is achieved.
[0008] Preferably, to facilitate the control function of allowing only the window sash to be opened (or tilted open) and not tilted open (or tilted open), as well as the locking and sealing function after the window sash is closed under this function, the turning angle position of the window sash connecting rod is an oblique connecting rod. The angles between the two ends of the oblique connecting rod and the horizontal and vertical bars of the window sash connecting rod are both obtuse angles. A screw hole is provided in the middle of the oblique connecting rod, and the control bolt passes through the screw hole. A stop is provided on the elastic band. The stop passes through the corresponding strip-shaped through hole on the bottom of the limiting groove and can be blocked by the control bolt after being screwed in, and can also be not blocked by the control bolt after being screwed out, and satisfy the following conditions: when the stop is blocked by the control bolt, the rotation range of the handle can only realize the tilting function of the window sash and the locking and sealing function after tilting open, and cannot realize the tilting function; or, the rotation range of the handle can only realize the tilting function of the window sash. It can lock and seal after the window sash is opened and closed, but cannot achieve the open-hung function; the lock seat includes two first lock seats and two second lock seats, one of the first lock seats and one of the second lock seats is installed on the corresponding vertical side of the window frame near the upper end, and the other of the first lock seats and the other of the second lock seats is installed on the corresponding vertical side of the window frame near the lower end. The lock head includes two first lock heads and two second lock heads, one of the first lock heads and one of the second lock heads is located on the vertical transmission rod near the upper end, and the other of the first lock heads and the other of the second lock heads is located on the vertical transmission rod near the lower end. The two first lock heads can be connected to the two first lock seats respectively and are used to achieve the locking and sealing function after the window sash is opened and closed. The two second lock heads can be connected to the two second lock seats respectively and are used to achieve the locking and sealing function after the window sash is opened and closed.
[0009] Preferably, to achieve both smooth opening and closing of the window sash and good stability after opening, the rotating assembly includes a slider, a first rotating rod, a second rotating rod, a third rotating rod, and a fourth rotating rod. The window frame connecting rod has a groove, and the lower part of the slider is placed within the groove and can slide along the length of the window frame connecting rod. The first rotating rod is rotatably connected to the crossbar of the window sash connecting rod near its first end. The second end of the first rotating rod is rotatably connected to the first end of the second rotating rod. The second end of the second rotating rod is rotatably connected to the slider. The first end is rotatably connected, the second end of the slider is rotatably connected to the first end of the third rotating rod, the second end of the third rotating rod is rotatably connected to the middle section of the fourth rotating rod, the first end of the fourth rotating rod is rotatably connected to the window frame connecting rod, the second end of the fourth rotating rod is rotatably connected to the middle section of the first rotating rod, the first rotating rod is located below the crossbar of the window sash connecting rod, and when the first rotating rod is parallel to the crossbar of the window sash connecting rod, the second end of the first rotating rod is close to the turning angle position of the window sash connecting rod.
[0010] Preferably, in order to achieve the function of opening the window sash only when the handle is rotated to 180°, two parallel limiting strips are provided on the upper part of the first rotating rod near its second end, and parallel to the length direction of the first rotating rod. The end of the transverse transmission rod near the elastic band is bent upward to form an arc shape, and a vertical first limiting post is provided at its lower part. The first limiting post passes through the corresponding through hole on the elastic band and is placed between the two limiting strips. It can be limited to move in the length direction of the first rotating rod and satisfy the following conditions: when the handle is rotated to the angle that allows the window sash to be opened, the first limiting post is just separated from the two limiting strips. When the handle is rotated to any other rotation position, the first limiting post is located between the two limiting strips.
[0011] Preferably, to avoid excessive friction between the first limiting post and the limiting strip, which would affect the smoothness of operation, the lower end of the first limiting post is provided with a square mushroom head with a larger outer diameter. In order to facilitate the adjustment of the tightness of the fit between the slider and the slide groove to adjust the tightness of the window opening and closing, the slider is provided with an adjusting screw for adjusting the tightness of the fit between the slider and the slide groove.
[0012] Preferably, to prevent the handle from rotating after it has been rotated 180° and completed the open-window function for security purposes, and to facilitate control of the maximum open-window angle, the first end of the first rotating rod is provided with a positioning groove. The position on the first rotating rod that is rotatably connected to the crossbar of the window sash connecting rod is located on the side of the positioning groove away from the first end of the first rotating rod. The middle position of the first end of the first rotating rod is provided with a notch communicating with the positioning groove. The lower part of the horizontal transmission rod near the positioning groove is provided with a vertical second limiting post. The lower end of the second limiting post passes through the corresponding strip-shaped through hole on the crossbar of the window sash connecting rod and satisfies the following conditions: when the handle is rotated to the angle that allows the window sash to be opened, the lower end of the second limiting post passes through the notch and is placed in the positioning groove; when the window sash is opened, the lower end of the second limiting post is located in the positioning groove and cannot be disengaged from the notch.
[0013] Preferably, for ease of transportation and storage and for easy assembly during installation, the crossbar of the window sash connecting rod includes two independent sections with semi-circular notches at one end of each section that are close to each other. The two semi-circular notches are joined together to form a circular through hole. A rivet is provided on the first rotating rod near its first end. The upper end of the rivet passes through the circular through hole and has a rivet head with an outer diameter larger than the diameter of the circular through hole.
[0014] Preferably, to reliably control the window sash's opening angle, overhang angle, and locked state after opening, a positioning gear is fixedly connected to the lower part of the first end of the fourth rotating rod. The lower part of the vertical connecting screw has external threads, while the upper middle part does not. The lower end of the connecting screw passes through the corresponding through hole at the first end of the fourth rotating rod and the vertical through hole of the positioning gear, and then connects to the corresponding screw hole of the window frame connecting rod. Two compression spring seats are provided on the window frame connecting rod near the positioning gear. Two positioning rods and a control rod are provided on the window frame connecting rod between the two compression spring seats. The first ends of the two positioning rods are respectively rotatably mounted on the window frame connecting rod via pins. One end of the control rod is connected to the two spring seats respectively, and the other end of the two springs is connected to the middle section of the two positioning rods respectively. The control rod is located between the two positioning rods, and a control handle is connected to the upper middle position of the control rod. The second ends of the two positioning rods are located on both sides of the positioning gear and satisfy the following conditions: when the control rod is rotated to the point where neither end of it is in contact with the two positioning rods, the two springs press down on the two positioning rods respectively and make their second ends lock the external teeth on the positioning gear and prevent the positioning gear from rotating; when the control rod is rotated to the point where its two ends are against the two positioning rods respectively, the second ends of the two positioning rods disengage from the external teeth on the positioning gear and allow the positioning gear to rotate.
[0015] Preferably, to further improve the control over the magnitude of the friction force during window sash opening and closing, wear-resistant pads are provided between the upper part of the positioning gear and the nut of the connecting screw, and between the lower part of the positioning gear and the window frame connecting rod. The screw of the connecting screw passes through the central through hole of the two wear-resistant pads. The two compression spring seats, the two positioning rods, the two compression springs, and the control rod are all placed inside the "L"-shaped control cover, and the control handle is located above the control cover. The control rod is mounted on the window frame connecting rod through a rotating shaft to achieve the positioning rotation function. Alternatively, the control rod achieves the positioning rotation function through the connection between itself and the control handle and the control cover.
[0016] Preferably, in order to achieve good corner transmission function, the elastic belt is a thin steel belt.
[0017] The beneficial effects of this invention are as follows:
[0018] This invention designs the window sash connecting rod as an "L" shape and installs an "L"-shaped turning angle connecting rod at its turning angle position. An elastic band is installed at the turning angle position of the "L"-shaped turning angle connecting rod. The elastic band transmits the movement function of the horizontal transmission rod to the vertical transmission rod, and the window sash locking and sealing function is achieved through the vertical side without a handle. Ultimately, it achieves a four-sided locking and sealing function, significantly improving the window sash locking and sealing effect. By designing the turning angle position of the window sash connecting rod as an angled connecting rod, it facilitates the installation of control bolts and easy rotation. A stop is set on the elastic band; rotating the control bolts can stop the stop, preventing further movement of the elastic band and thus preventing further rotation of the handle. Thus, by properly designing the position of the stop on the elastic band, it is possible to achieve window sash opening control functions that allow only cantilevered opening and not hinged opening (e.g., for security reasons in hotels) or only hinged opening and not cantilevered opening (this function is generally not used, but may be necessary in special circumstances). (For use in various situations), and through the design of two first lock heads, two first lock seats, two second lock heads, and two second lock seats, respectively, the locking and sealing functions are realized in the window opening control function that only allows the window sash to be opened and not allowed to be opened, or only allows the window sash to be opened and not allowed to be opened, as well as the locking and sealing function when the handle is in the initial position, i.e., rotated 0°. By setting mutually cooperating limit strips and first limit posts, the function of opening the window sash can be realized only when the handle is rotated to 180°. By setting mutually cooperating positioning grooves and second limit posts, the function of preventing the handle from rotating after it has been rotated to 180° and opened can be realized, so as to avoid malfunction of the handle transmission function, and at the same time, it can limit the maximum opening angle of the window sash. By designing mutually cooperating positioning gears, control rods, positioning rods, and compression springs, the function of reliably controlling the window sash opening angle, opening angle, and locking state after opening can be realized, so that the window sash has stronger wind resistance after opening, and at the same time, the safety of use is improved.

[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] like Figures 3-10 As shown, the multifunctional sliding support and steering angle control assembly for outward-opening top-hung windows of the present invention includes components for use with the window sash ( Figures 3-9 Not shown, see reference Figure 1 and Figure 2 The window sash 1) is connected to a window sash connecting rod (refer to the horizontal rod 13, vertical rod 5 and diagonal connecting rod 10 below, which are connected together to form a window sash connecting rod), a horizontal transmission rod 18 for transmission, and a rod for connection with the window frame ( Figures 3-9 Not shown, see reference Figure 1 and Figure 2 The window frame 3) is connected to the lower side by a window frame connecting rod 24, an "L"-shaped steering angle connecting rod 8, an elastic band 9, a vertical transmission rod 7, and a lock seat (refer to the first lock seat 6 and the second lock seat 4 below). A handle is installed on one vertical side of the window sash. Figures 3-9 Not shown, see reference Figure 1 and Figure 2The window sash connecting rod and the window frame connecting rod 24 are connected by a rotating assembly. The window sash connecting rod is "L"-shaped, with its horizontal bar 13 connected to the lower side of the window sash and its vertical bar 5 connected to the vertical side of the window sash without a handle. The rotating assembly is installed between the horizontal bar 13 of the window sash connecting rod and the window frame connecting rod 24. The "L"-shaped turning angle connecting rod 8 is installed at the turning angle position of the window sash connecting rod. The turning angle position of the "L"-shaped turning angle connecting rod 8 is arc-shaped and has a strip-shaped limiting groove (in the figure). (Unmarked), the limiting groove is "L" shaped and its turning angle position is arc-shaped. The elastic band 9 is placed in the limiting groove. The two ends of the elastic band 9 are respectively connected to one end of the horizontal transmission rod 18 and one end of the vertical transmission rod 7. The vertical transmission rod 7 is provided with a lock head (refer to the first lock head 42 and the second lock head 40 below). The lock head can be connected to the lock seat (refer to the first lock seat 6 and the second lock seat 4 below) after passing through the corresponding strip-shaped through hole on the vertical rod 5 of the window sash connecting rod. The lock seat is installed on the corresponding vertical side of the window frame.
[0031] like Figures 3-10 As shown, the present invention also discloses the following more optimized specific structures:
[0032] To facilitate the control function of allowing only the window sash to be opened (or tilted open) and not tilted open (or tilted open), as well as the locking and sealing function after the window sash is closed under this function, the turning angle position of the window sash connecting rod is an oblique connecting rod 10. The two ends of the oblique connecting rod 10 form obtuse angles with the horizontal bar 13 and the vertical bar 5 of the window sash connecting rod, respectively. A screw hole is provided in the middle of the oblique connecting rod 10, and the control bolt 32 passes through the screw hole. A stop block 35 is provided on the elastic band 9, and the stop block 35 passes through the corresponding groove bottom of the limiting groove. The strip-shaped through hole can be blocked by the control bolt 32 after being screwed in, and can also be unblocked by the control bolt 32 after being screwed out, and meets the following conditions: when the stop block 35 is blocked by the control bolt 32, the rotation range of the handle can only realize the open-hung function of the window sash and the locking and sealing function after closing the open-hung function, and cannot realize the swing-open function (i.e., the handle can only rotate between 135° and 180°), or, the rotation range of the handle can only realize the swing-open function of the window sash and the locking function after closing the swing-open function. The window sash has a closed sealing function and cannot be opened (i.e., the handle can only rotate between 0° and 90°). The lock base includes two first lock bases 6 and two second lock bases 4. One first lock base 6 and one second lock base 4 are installed on the corresponding vertical side of the window frame near the upper end, and the other first lock base 6 and the other second lock base 4 are installed on the corresponding vertical side of the window frame near the lower end. The lock head includes two first lock heads 42 and two second lock heads 40. One first lock head 42 and one second lock head 40 are located on the vertical transmission rod 7 near the upper end, and the other first lock head 42 and the other second lock head 40 are located on the vertical transmission rod 7 near the lower end. The two first lock heads 42 can be connected to the two first lock bases 6 respectively and are used to realize the locking and sealing function after the window sash is opened and then closed. The two second lock heads 40 can be connected to the two second lock bases 4 respectively and are used to realize the locking and sealing function after the window sash is opened and then closed (lock bases and lock heads are installed at both the upper and lower ends to achieve the best locking and sealing function).
[0033] To ensure both smooth opening and closing of the window sash and good stability after opening, the rotating assembly includes a slider 21, a first rotating rod 12, a second rotating rod 20, a third rotating rod 22, and a fourth rotating rod 25. A groove (not marked in the figure) is provided on the window frame connecting rod 24. The lower part of the slider 21 is placed within the groove and can slide along the length of the window frame connecting rod 24. The first rotating rod 12 is rotatably connected to the crossbar 13 of the window sash connecting rod near its first end. The second end of the first rotating rod 12 is rotatably connected to the first end of the second rotating rod 20. The second end of the second rotating rod 20 is connected to the slider. The first end of the slider 21 is rotatably connected to the second end of the third rotating rod 22. The second end of the third rotating rod 22 is rotatably connected to the middle section of the fourth rotating rod 25. The first end of the fourth rotating rod 25 is rotatably connected to the window frame connecting rod 24. The second end of the fourth rotating rod 25 is rotatably connected to the middle section of the first rotating rod 12. The first rotating rod 12 is located below the horizontal bar 13 of the window sash connecting rod. When the first rotating rod 12 is parallel to the horizontal bar 13 of the window sash connecting rod, the second end of the first rotating rod 12 is close to the turning angle position of the window sash connecting rod.
[0034] To enable the handle to be rotated to 180° for the window sash to open, two parallel limiting strips 11 are provided on the upper part of the first rotating rod 12 near its second end. The transverse transmission rod 18 is curved upward at one end near the elastic band 9 to form an arc-shaped part 33, and a vertical first limiting post 33 is provided at its lower part. The first limiting post 33 passes through the corresponding through hole on the elastic band 9 and is placed between the two limiting strips 11. It can be limited to move in the length direction of the first rotating rod 12 and meets the following conditions: when the handle is rotated to the angle that allows the window sash to open (i.e., when the handle is rotated to 180°), the first limiting post 33 is just separated from the two limiting strips 11. When the handle is rotated to any other rotation position, the first limiting post 33 is located between the two limiting strips 11.
[0035] To avoid excessive friction between the first limiting post 33 and the limiting strip 11, which would affect the smoothness of operation, the lower end of the first limiting post 33 is provided with a square mushroom head with a larger outer diameter. In order to facilitate the adjustment of the tightness of the fit between the slider 21 and the slide groove to adjust the tightness of the opening and closing of the window sash, the slider 21 is provided with an adjusting screw 41 for adjusting the tightness of the fit between the slider 21 and the slide groove.
[0036] To prevent the handle from rotating after it has been rotated 180° and completed its open-end function, thus enhancing security and facilitating control of the maximum open-end angle of the window sash, a positioning groove 15 is provided at the first end of the first rotating rod 12. The position on the first rotating rod 12 that is rotatably connected to the horizontal bar 13 of the window sash connecting rod is located on the side of the positioning groove 15 away from the first end of the first rotating rod 12. A notch 23 communicating with the positioning groove 15 is provided in the middle of the first end of the first rotating rod 12. A vertical second limit is provided on the lower part of the horizontal transmission rod 13 near the positioning groove 15. Position post 16, the lower end of the second limiting post 16 passes through the corresponding strip-shaped through hole on the crossbar 13 of the window sash connecting rod and satisfies the following conditions: when the handle is rotated to the angle that allows the window sash to be suspended (i.e., when the handle is rotated to 180°), the lower end of the second limiting post 16 passes through the notch 23 and is placed in the positioning groove 15. When the window sash is suspended, the lower end of the second limiting post 16 is located in the positioning groove 15 and cannot be disengaged from the notch 23. The window sash suspension angle corresponding to the lower end of the second limiting post 16 and the positioning groove 15 moving to the point where they cannot move is the maximum angle at which the window sash can be suspended.
[0037] To facilitate transportation and storage and easy assembly during installation, the crossbar 13 of the window sash connecting rod includes two independent sections with semi-circular notches at one end of each section that is close to each other. The two semi-circular notches are joined together to form a circular through hole. A rivet 14 is provided on the upper part of the first rotating rod 12 near its first end. The upper end of the rivet 14 passes through the circular through hole and has a rivet head with an outer diameter larger than the diameter of the circular through hole.
[0038] To reliably control the window sash's opening angle, overhang angle, and locking status after opening, a positioning gear 26 is fixedly connected to the lower part of the first end of the fourth rotating rod 25. The lower part of the vertical connecting screw 27 has external threads, while the upper middle part does not. The lower end of the connecting screw 27 passes through the corresponding through hole at the first end of the fourth rotating rod 25 and the vertical through hole of the positioning gear 26, and then connects to the corresponding screw hole of the window frame connecting rod 24. Two spring seats 29 are located on the window frame connecting rod 24 near the positioning gear 26. Two positioning rods 36 and a control rod 37 are located on the window frame connecting rod 24 between the two spring seats 29. The first ends of the two positioning rods 36 are rotatably mounted on the window frame connecting rod 24 via pins 38. One end of spring 39 is connected to two spring seats 29 respectively, and the other end of spring 39 is connected to the middle section of two positioning rods 36 respectively. Control rod 37 is located between two positioning rods 36. Control handle 30 is connected to the upper middle position of control rod 37. The second ends of the two positioning rods 36 are located on both sides of positioning gear 26 and meet the following conditions: when control rod 37 rotates to the point where neither end of it contacts the two positioning rods 36, the two springs 39 press down on the two positioning rods 36 respectively and make their second ends lock the external teeth on positioning gear 26 and prevent positioning gear 26 from rotating. When control rod 37 rotates to the point where its two ends press against the two positioning rods 36 respectively, the second ends of the two positioning rods 36 disengage from the external teeth on positioning gear 26 and allow positioning gear 26 to rotate.
[0039] To further improve the control over the friction force of opening and closing the window sash, wear-resistant shims 28 are provided between the upper part of the positioning gear 26 and the nut of the connecting screw 27, and between the lower part of the positioning gear 26 and the window frame connecting rod 24. The wear-resistant shims 28 can be made of copper. The screw of the connecting screw 27 passes through the central through hole of the two wear-resistant shims 28. The two spring seats 29, the two positioning rods 36, the two springs 39 and the control rod 37 are all placed inside the "L"-shaped control cover 31 and the control handle 30 is located above the control cover 31. The control rod 37 is mounted on the window frame connecting rod 24 through a rotating shaft to achieve the positioning rotation function. Alternatively, the control rod 37 achieves the positioning rotation function through the connection between itself and the control handle 30 and the control cover 31.
[0040] To achieve good corner transmission function, the elastic belt 9 is a thin steel belt.
[0041] Figure 3 and Figure 6 The diagram also shows a limiting screw 17 installed on the crossbar 13 of the window sash connecting rod. The limiting screw 17 passes through a corresponding strip-shaped through hole on the transverse transmission rod 18 to limit the movement of the transverse transmission rod 18. Figure 3 and Figure 8Also shown is a drive rod 19 for connection to or extension of a handle, which is connected to the transverse drive rod 18 and the two are interconnected by a rack; these are all conventional adaptive structures.
[0042] Combination Figures 1-10 In application, the multifunctional sliding support and steering angle control assembly described in this invention are installed on an outward-opening top-hung window, and the horizontal bar 13 and vertical bar 5 of the window sash connecting rod are respectively connected to the window sash (see reference). Figure 1 and Figure 2 The lower side of window sash 1) and without handle (see reference) Figure 1 and Figure 2 Connect the vertical side of handle 2) to the window frame connecting rod 24 and the window frame (see reference). Figure 1 and Figure 2 The lower side connection of the window frame 3); the following is a detailed explanation of its various functions based on the rotation angle of the handle:
[0043] When the handle is in its initial state, i.e. rotated 0° or vertically downward, the two second lock heads 40 and the two second lock seats 4 are engaged and connected to achieve the locking and sealing function between the vertical side of the window sash without the handle and the window frame. The locking and sealing function of the other three sides (i.e., the upper side, the lower side and the vertical side with the handle) between the window sash and the window frame is achieved using existing conventional technology.
[0044] Before opening the window sash, first rotate the control handle 30 so that the control lever 37 rotates until its two ends abut against the two positioning levers 36. At this time, the second ends of the two positioning levers 36 separate from the external teeth of the positioning gear 26, and the fourth rotating lever 25 can rotate freely relative to the window frame connecting rod 24. Alternatively, if the control handle 30 is already in this state, no operation is required. Then, use a tool such as an "L" wrench to loosen the control bolt 32 slightly (only a small movement is needed to achieve this), so that the inner end of the control bolt 32 does not block the stop block 35 on the elastic band 9. Alternatively, if it is necessary to achieve a control function that only allows the window sash to open and not to be suspended, as well as a locking and sealing function after the window sash is closed under this function, use a tool such as an "L" wrench to loosen the control bolt 32 slightly (only a small movement is needed to achieve this), so that the inner end of the control bolt 32 can block the stop block 35 on the elastic band 9. Alternatively, if the control bolt 32 is already in this state, no operation is needed. Then you can rotate the handle.
[0045] When the handle is rotated 90° to the horizontal position, the two second lock cylinders 40 separate from the two second lock seats 4. At this time, the window sash can be opened outwards. The user can open the window sash by holding the handle and pushing it outwards. Figure 8As shown, during the outward opening process, the first rotating rod 12 does not rotate, while the second rotating rod 20, the third rotating rod 22, the fourth rotating rod 25, and the positioning gear 26 rotate adaptively, and the slider 21 moves adaptively, working together to complete the outward opening function. The friction force during the opening process, i.e., the opening resistance, is mainly determined by the friction force between the slider 21 and the slide groove, and the friction force between the wear-resistant pad 28 and the associated components. When the window sash is in the outward opening state, the first limiting post 33 is always located between the two limiting strips 11, and the window sash cannot achieve the suspended opening function. In this state, if the user needs to lock the opening angle and the stable state of this angle, the control handle 30 is rotated to make the control rod 37 rotate until its two ends are separated from the two positioning rods 36 respectively. At this time, the second ends of the two positioning rods 36 abut against the outer teeth of the positioning gear 26 under the action of the corresponding compression springs 39, and the fourth rotating rod 25 cannot rotate freely relative to the window frame connecting rod 24, thus realizing the locking function of the outward opening angle of the window sash.
[0046] When the user needs to open the window, firstly, use a tool such as an "L" wrench to loosen the control bolt 32 slightly (only a small movement is needed to achieve this), so that the inner end of the control bolt 32 does not block the stop 35 on the elastic band 9. Alternatively, if the control bolt 32 is already in this state, no operation is required. Then, the user holds the handle to close the window sash, and then rotates the handle upwards by 90° (a total rotation of 180°, i.e., vertically upwards). At this point, the first limiting post 33 separates from the two limiting strips 11, and simultaneously, the lower end of the second limiting post 16 passes through the notch 23 and is placed in the positioning groove 15. At this point, the window sash can achieve the open / close function. If the control handle 30 locks the positioning gear 26 and prevents it from rotating, the control handle 30 needs to be rotated in the aforementioned manner to allow the positioning gear 26 to rotate freely in order to achieve the open / close function. The user can directly push the lower side of the window sash to a suitable or extreme position to complete the open / close function. Figure 9As shown, during the opening process, the first rotating rod 12, the second rotating rod 20, the third rotating rod 22, the fourth rotating rod 25, and the positioning gear 26 rotate adaptively, and the slider 21 moves adaptively, working together to complete the opening function. At this time, if it is necessary to achieve the control function that only allows the window sash to be opened and not allowed to be opened horizontally, as well as the locking and sealing function after the window sash is closed under this function, the control bolt 32 is screwed in a little bit using a tool such as an "L" wrench (only a small movement is needed to achieve the purpose), so that the inner end of the control bolt 32 can block the stop block 35 on the elastic band 9. In this state, the handle can only rotate between 135° and 180° and cannot return to 90°, so the horizontal opening function cannot be achieved; at the same time, the lower end of the second limiting post 16 is placed in the positioning groove 15 and cannot be disengaged from the positioning groove 15 through the notch 23. The handle can only rotate slightly within the range limited by the positioning groove 15 to the second limiting post 16, thus avoiding the problem of mutual interference of transmission functions caused by the random rotation of the handle. In this state, if the user needs to lock the opening angle and its stable state, rotating the control handle 30 causes the control rod 37 to rotate until its two ends separate from the two positioning rods 36. At this time, the second ends of the two positioning rods 36 abut against the outer teeth of the positioning gear 26 under the action of the corresponding compression springs 39. The fourth rotating rod 25 cannot rotate freely relative to the window frame connecting rod 24, thus realizing the locking function of the window sash opening angle. If the user wants to close the window sash, he first holds the handle and pulls the window sash back. At this time, the lower end of the second limiting post 16 separates from the positioning groove 15 through the notch 23. Then, the handle is rotated to 135°, and the two first lock heads 40 are respectively engaged with the two first lock seats 4 to realize the locking and sealing function between the vertical side of the window sash without the handle and the window frame. The locking and sealing function of the other three sides (i.e., the upper side, the lower side, and the vertical side with the handle) between the window sash and the window frame is realized using existing conventional technology, thus realizing the window sash locking and sealing function under the open function.

Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
