Description

Technical Field

[0001] This invention belongs to the field of door and window manufacturing, and particularly relates to an outward-opening window device and a door / window. Background Technology

[0002] Existing outward-opening windows require manual operation of locking mechanisms (such as bolts) to unlock the window sash from the window frame when the window needs to be opened, followed by control of the window sash opening via a control unit. When the window needs to be closed, the control unit closes the window sash onto the window frame, and then the locking mechanism is manually operated to lock the window sash onto the window frame. This type of window opening and closing structure makes the operation of the window sash cumbersome, the opening and closing efficiency of the window sash low, and the user experience poor. Summary of the Invention

[0003] The outward-opening window device provided by this invention aims to solve the problems of cumbersome operation steps, low efficiency in opening and closing the window sash, and poor user experience caused by the existing window opening and closing structure.

[0004] This invention is implemented as follows: an outward-opening window device, comprising:

[0005] A linkage assembly for movably connecting the window sash and the window frame to drive the window sash to open or close;

[0006] A drive assembly is disposed on the window frame and drives the linkage assembly to open or close the window sash. The drive assembly includes a movable first locking element.

[0007] A clutch assembly is provided on the window frame and connected to the linkage assembly. The clutch assembly can be linked with or disengaged from the drive assembly when the first locking member moves.

[0008] A first lock base is movably disposed on the window sash and can cooperate with the first locking member to move with the locking member;

[0009] The second lock seat is fixed to the window frame;

[0010] The second locking element is movably disposed on the window sash and linked with the second lock seat. The second locking element can cooperate with the second lock seat to lock the window sash onto the window frame.

[0011] When the drive assembly is linked with the clutch assembly, the drive assembly drives the linkage assembly to open or close the window sash;

[0012] When the drive assembly disengages from the clutch assembly, the first locking member engages with the first lock seat, and the drive assembly drives the first locking member to move the first lock seat so that the second locking member engages with or disengages from the second lock seat.

[0013] Furthermore, the driving assembly also includes a first moving member disposed on the bottom edge of the window frame and movable along the length direction of the bottom edge of the window frame. The first locking member is fixedly disposed on the first moving member. The clutch assembly includes a base plate fixedly disposed on the bottom edge of the window frame and a first locking hook movable on the base plate along the length direction of the bottom edge of the window frame. The first locking hook is connected to the linkage assembly. When the first moving member moves to a first preset position in a first direction, the first moving member cooperates with the first locking hook to make the driving assembly and the clutch assembly linked. When the first moving member moves to a second preset position in a second direction opposite to the first direction, the first moving member separates from the locking hook to make the driving assembly and the clutch assembly separate.

[0014] Furthermore, the first moving member is arranged parallel to the base plate and located above the base plate. The base plate is provided with a strip-shaped through groove that extends along the moving direction of the first moving member. The clutch assembly also includes a slider that is slidably disposed in the strip-shaped through groove. The first locking hook is rotatably disposed on the slider in a direction perpendicular to the horizontal direction. The connecting rod assembly is connected to the first locking hook through the slider. The first moving member is provided with a first through groove.

[0015] When the first movable member moves to the first preset position in the first direction, the first locking hook rotates and engages with the first through groove;

[0016] When the first moving member moves to the first preset position in the second direction, the first locking hook rotates and separates from the first through groove.

[0017] Furthermore, the first moving member has a second through groove on one side of the first through groove along its moving direction. The slider and the first locking hook are both placed in the second through groove. When the first moving member moves along the first direction, the side wall of the second through groove near the first through groove can push the slider to move. The front end of the first locking hook has a beveled surface. The clutch assembly also includes a first elastic member disposed on the base plate. The first elastic member provides a preload force to keep the first locking hook horizontal. When the first moving member moves along the first direction to a first preset position, the side wall of the second through groove moves along the beveled surface to make the first locking hook rotate. The first locking hook cooperates with the first through groove. When the first moving member moves along the second direction to a first preset position, the side wall of the strip through groove moves along the beveled surface to make the first locking hook rotate. The first locking hook disengages from the first through groove.

[0018] Furthermore, the driving component also includes:

[0019] The first mounting base is fixed to the bottom edge of the window frame, and the first movable member is movably mounted on the first mounting base. The first movable member is provided with a plurality of limiting parts spaced apart along the moving direction of the first movable member.

[0020] A gear is rotatably mounted on the first mounting base and engages with at least two of the limiting portions;

[0021] The handle is located on the inner side of the bottom edge of the window frame and is connected to the gear.

[0022] Furthermore, the drive assembly includes a second moving member and a third moving member disposed on the bottom edge of the window frame and movable along the length direction of the bottom edge of the window frame, the first locking member being disposed on the third moving member, and the clutch assembly including a first locking hook movably disposed on the second moving member, the first locking hook being connected to the linkage assembly;

[0023] When the third moving member moves to the first preset position in the first direction, the second moving member can cooperate with the first locking hook to make the driving component and the clutch component work together.

[0024] When the third moving member moves to the first preset position in a second direction opposite to the first direction, the third moving member can separate from the first locking hook to separate the drive assembly and the clutch assembly. Further, the third moving member is arranged parallel to and above the second moving member. The second moving member has a strip-shaped through groove extending along the moving direction of the second moving member. The clutch assembly also includes a slider slidably disposed within the strip-shaped through groove. The first locking hook is rotatably disposed on the slider in a direction perpendicular to the horizontal direction. The connecting rod assembly is connected to the first locking hook via the slider. The third moving member has a first through groove.

[0025] When the third moving member moves to the first preset position in the first direction, the first locking hook rotates and engages with the first through groove;

[0026] When the third moving member moves to the first preset position in the second direction, the first locking hook rotates and separates from the first through groove.

[0027] Furthermore, the bottom of the second moving member is provided with a blocking member, one end of which extends into the strip-shaped through groove. The third moving member is provided with a second through groove on one side of the first through groove along its moving direction. The slider and the first locking hook are both placed in the second through groove. When the third moving member moves along the first direction, the side wall of the second through groove near the first through groove can push the slider to move. The front end of the first locking hook is provided with a chamfered surface. The clutch assembly also includes a first elastic member provided on the second moving member. The first elastic member provides a preload force to the first locking hook to keep it horizontal. When the third moving member moves along the first direction to a first preset position, the side wall of the second through groove can move along the chamfered surface to make the first locking hook rotate. The first locking hook cooperates with the first through groove. When the third moving member moves along the second direction to a first preset position, the blocking member moves along the chamfered surface to make the first locking hook rotate, and the first locking hook disengages from the first through groove.

[0028] Furthermore, the outward-opening window device also includes a self-locking component that locks the first locking hook to keep it in its current state when the first locking hook is separated from the third moving member.

[0029] Furthermore, the self-locking component includes:

[0030] The second mounting bracket is fixed to the bottom edge of the window frame;

[0031] The second locking hook is rotatably mounted on the second mounting base;

[0032] A limiting member is provided on the slider and can move with the slider. When the third moving member cooperates with the first locking hook and moves to the first preset position in the second direction, the limiting member cooperates with the second locking hook and drives the second locking hook to rotate.

[0033] The support rod has one end rotatably connected to the second locking hook and the other end movably connected to the second mounting base;

[0034] The second elastic element is provided on the support rod. When the limiting element is not engaged with the second locking hook, the second elastic element is in a compressed state. When the limiting element is engaged with the second locking hook, the second elastic element is in a normal state.

[0035] When the limiting member engages with the second locking hook, the restoring force of the elastic member in its normal state provides a resisting force through the limiting member to the first locking hook, keeping it detached from the first through groove.

[0036] Furthermore, the driving component also includes:

[0037] The first movable component is movable along the length of the bottom edge of the window frame and connected to the second movable component. The first movable component is provided with a plurality of limiting parts spaced apart along its moving direction.

[0038] The first mounting base is located on the bottom edge of the window frame;

[0039] A gear is rotatably mounted on the first mounting base and engages with at least two of the limiting portions;

[0040] The handle is located on the inner side of the bottom edge of the window frame and is linked to the gear.

[0041] Furthermore, the linkage assembly includes:

[0042] The first connecting rod is hinged at one end to the bottom edge of the window sash and at the other end to the bottom edge of the window frame.

[0043] The second link is hinged at one end to the first link and movably connected at the other end to the clutch assembly.

[0044] Furthermore, the first elastic element is a helical spring, and the tail end of the first locking hook is rotatably connected to the slider. The slider is provided with a receiving groove near the tail end of the first locking hook to accommodate the helical spring. The tail end of the first locking hook is provided with a snap-fit ​​part, which extends into the receiving groove and is inserted into the helical spring from the side. When the first locking hook is horizontally positioned, the elastic element is in its normal state. When the first locking hook rotates in a direction perpendicular to the horizontal, the snap-fit ​​part pulls the elastic element to stretch it.

[0045] The present invention also provides a door and window, characterized in that it comprises:

[0046] window frame;

[0047] Window sash, movably mounted on the window frame; and

[0048] In the aforementioned outward-opening window device, the linkage assembly is movably connected to the window sash and the window frame to drive the window sash to open or close.

[0049] The beneficial effects achieved by this invention are that by setting the clutch component and the drive component to be separated or engaged, the drive component can be linked or disengaged with the linkage component. That is, when the clutch component and the drive component are engaged, the drive component can drive the linkage component to control the opening or closing of the window sash. When the clutch component and the drive component are disengaged, the connection between the drive component and the linkage component is released, and at the same time, the first locking member and the first locking seat are engaged. The drive component can drive the first locking member to move the first locking seat and the second locking member, so that the second locking member can engage or disengage with the second locking seat. This allows the window sash to be locked to the window frame or unlocked from the window frame, realizing a series of functions such as unlocking, opening, closing, and locking of the window sash. This simplifies the opening and locking operation steps of the window sash and improves the user experience. The advantages of this outward-opening window device are particularly prominent when there are certain obstructions around some doors and windows, such as doors and windows on kitchen countertops, where it is impossible for a person to reach the window sash to operate it.

[0065] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0066] See Figures 1-5 This invention provides an outward window opener 10, which includes a linkage assembly 1, a drive assembly 2, a clutch assembly 4, a first lock seat 5, a second lock seat 6, and a second locking member 7. The linkage assembly 1 is movably connected to the window sash 30 and the window frame 20 to drive the window sash 30 to open or close. The drive assembly 2 is located on the window frame 20 and drives the linkage assembly 1 to open or close the window sash 30. The drive assembly 2 includes a movably disposed first locking member 3. A clutch assembly 4 is located on the window frame 20 and connected to the linkage assembly 1. The clutch assembly 4 can be linked with or disengaged from the drive assembly 2 when the first locking member 3 moves. A first lock seat 5 is movably disposed on the window sash 30 and can cooperate with the first locking member 3 to move with the locking member. A second lock seat 6 is fixed on the window frame 20, specifically located on the side of the window frame 20. A second locking member 7 is movably disposed on the window sash 30 and is linked with the second lock seat 6 so that the second locking member 7 can move when the second lock seat 6 moves. The second locking member 7 can cooperate with the second lock seat 6 to lock the window sash 30 to the window frame 20. When placed on the side of the window frame 20, the second locking member 7 is correspondingly set on the side of the window sash 30. Based on this, the second locking member 7 can be connected to the second lock seat 6 through the angle transmission 100. When the drive assembly 2 is linked with the clutch assembly 4, the drive assembly 2 drives the linkage assembly 1 to open or close the window sash 30. That is, the drive assembly 2 drives the linkage assembly 1 through the clutch assembly 4 to close the window sash 30 on the window frame 20 and put it in an unlocked state or to push the window sash 30 open. When the drive assembly 2 is separated from the clutch assembly 4, the first locking member 3 cooperates with the first lock seat 5. The drive assembly 2 drives the first locking member 3 to move the first lock seat 5 so that the second locking member 7 cooperates or separates from the second lock seat 6, so as to avoid interference from the linkage assembly 1 when the drive assembly 2 drives the first locking member 3 to move the first lock seat 5 and the second locking member 7 to move so that the second locking member 7 separates or cooperates with the second lock seat 6.

[0067] By setting the clutch assembly 4 to be either disengaged or engaged with the drive assembly 2, the drive assembly 2 can be linked or disengaged from the linkage assembly 1. That is, when the clutch assembly 4 and the drive assembly 2 are engaged, the drive assembly 2 can drive the linkage assembly 1 to control the opening or closing of the window sash 30. When the clutch assembly 4 and the drive assembly 2 are disengaged, the connection between the drive assembly 2 and the linkage assembly 1 is released, and at the same time, the first locking member 3 and the first lock seat 5 are engaged. The drive assembly 2 can drive the first locking member 3 to move the first lock seat 5 and the second lock... The movement of the fixed part 7 allows the second locking part 7 to engage or disengage with the second locking seat 6, thereby locking the window sash 30 onto the window frame 20 or unlocking the window sash 30 from the window frame 20. This realizes a series of functions such as unlocking, opening, closing, and locking of the window sash 30, simplifying the opening and locking operation steps of the window sash 30 and improving the user experience. When applied to some doors and windows where there are certain obstructions around them, such as doors and windows on kitchen countertops, and when a person cannot reach the window sash 30 to operate it, the advantages of this outward-opening window device 10 are particularly highlighted.

[0068] The outward-opening window device 10 provided by the present invention can realize a series of functions such as unlocking, opening, closing and locking of window sash 30 through the driving component 2, which simplifies the opening and locking operation of window sash 30 and improves the user experience.

[0069] To better understand the working principle of the outward-opening window device 10 provided in this embodiment, this example illustrates the initial state with the window sash 30 closed and locked to the window frame 20 (see [reference]). Figure 3 At this time, the clutch assembly 4 is disengaged from the drive assembly 2, and thus the drive assembly 2 is also disengaged from the linkage assembly 1. The second locking member 7 and the second locking seat 6 are also engaged to lock the window sash 30 onto the window frame 20 (see [link]). Figure 5 );

[0070] When it is necessary to open the window sash 30, the drive assembly 2 causes the first locking member 3 to move away from its current position (i.e., the second preset position described below) in a first direction, thereby disengaging the second locking member 7 and the second lock seat 6 (see...). Figure 4 At this time, the window sash 30 and the window frame 20 are in the unlocked state, but the window sash 30 is still closed on the window frame 20 (see [link]). Figure 3The drive assembly 2 continues to move the first locking member 3 to the first preset position along the current direction. At this time, the drive assembly 2 is linked with the clutch assembly 4. Before this, the window sash 30 is still in the closed state. After the drive assembly 2 and the clutch assembly 4 are linked, the drive assembly 2 is connected with the linkage assembly 1. The drive assembly 2 causes the first locking member 3 to continue to move along the current direction, and the linkage assembly 1 drives the window sash 30 to push out of the window frame to open the window sash. At the same time, the first lock seat 5 also separates from the first locking member 3 as the window sash 30 leaves the first locking member 3.

[0071] When it is necessary to close the window sash 30, the first locking member 3 is moved in a second direction opposite to the first direction by the drive assembly 2. Under the action of the linkage assembly 1, the window sash 30 is pulled back until it is closed on the window frame 20. At the same time, the first locking member 3 moves to the first preset position and the first lock seat 5 engages with the first locking member 3 (see...). Figure 4 or Figure 5 At this first preset position, the clutch assembly 4 and the drive assembly 2 have also separated, causing the first locking member 3 to continue moving in the second direction. The first locking member 3 drives the first lock seat 5 to move, thereby driving the second locking member 7 to move to the second preset position. At this time, the second locking member 7 and the second lock seat 6 cooperate (see...). Figure 5 This will lock the window sash 30.

[0072] See Figures 4-5 Specifically, the first lock seat 5 is provided with a groove 51 that can cooperate with the first locking member 3. The groove 51 has an opening on at least one side along the direction perpendicular to the bottom edge of the window frame 20 for the first locking member 3 to enter and exit (not shown in the figure). The side of the groove 51 with the opening faces the side of the window sash 30 in the closing direction, so that when the drive assembly 2 drives the linkage assembly 1 to drive the window sash 30 to be completely closed on the window frame 20, the first locking member 3 can enter and exit the groove 51 from the opening.

[0073] See Figure 5 Specifically, the second lock seat 6 is provided with a blocking part 61 protruding from the surface of the window frame 20. When the second locking member 7 is moved to the second preset position by the first lock seat 5, the second locking member 7 moves to one side of the blocking part 61, which is the side away from the window sash 30, so as to restrict the window sash 30 from opening outward.

[0074] See Figure 1Specifically, the linkage assembly 1 includes a first linkage 11 and a second linkage 12. One end of the first linkage 11 is hinged to the bottom edge of the window sash 30, and the other end is hinged to the bottom edge of the window frame 20, so as to provide the window sash 30 with the conditions for movement during the opening or closing of the window sash 30. One end of the second linkage 12 is hinged to the first linkage 11, and the other end is movably connected to the clutch assembly 4 so that the clutch assembly 4 can link the linkage assembly 1 with the drive assembly 2. When the drive assembly 2 provides power to the linkage assembly 1, the second linkage 12 can push the first linkage 11 to drive the window sash 30 to rotate.

[0075] Example 1

[0076] See Figure 6 Furthermore, the drive assembly 2 also includes a first moving member 21 disposed on the bottom edge of the window frame 20 and movable along the length of the bottom edge of the window frame 20. A first locking member 3 is fixedly disposed on the first moving member 21. The clutch assembly 4 includes a base plate 41 fixedly disposed on the bottom edge of the window frame 20 and a first locking hook 42 movable along the length of the bottom edge of the window frame 20 disposed on the base plate 41. The first locking hook 42 is connected to the linkage assembly 1, that is, the first locking hook 42 is connected to the aforementioned second linkage 12 so that when the locking hook moves, it can drive the second linkage 12 to move, thereby driving the window sash 30 to open or close. When the first moving member 21 moves to the first preset position in the first direction, the first moving member 21 and the first locking hook 42 cooperate to make the drive assembly 2 and the clutch assembly 4 linked, so that the drive assembly 2 can control the linkage assembly 1 to open the window sash (see Figure 2 When the first moving member 21 moves to the first preset position in a second direction opposite to the first direction, the first moving member 21 separates from the locking hook to separate the drive assembly 2 and the linkage assembly 1. The engagement or disengagement of the locking hook with the first moving member 21 allows the drive assembly 2 to control the linkage assembly 1 to close the window sash 30. After that, the drive assembly 2 disconnects from the linkage assembly 1 (see [link]). Figure 6 ).

[0077] See Figure 6 Furthermore, the first moving member 21 is arranged parallel to the base plate 41 and located above the base plate 41. The base plate 41 is provided with a strip-shaped through groove 1a, which extends along the moving direction of the first moving member 21. The clutch assembly 4 also includes a slider 43 slidably disposed in the strip-shaped through groove 1a. The first locking hook 42 is rotatably disposed on the slider 43 in a direction perpendicular to the horizontal direction. The connecting rod assembly 1 is connected to the first locking hook 42 through the slider 43, that is, the second connecting rod 12 of the connecting rod assembly 1 is connected to the slider 43, so that the slider 43, the first locking hook 42, and the connecting rod assembly 1 form a whole. The first moving member 21 is provided with a first through groove 2a. When the first moving member 21 moves to the first preset position in the first direction, the first locking hook 42 rotates and engages with the first through groove 2a (see...). Figure 2This causes the drive assembly 2 and the clutch assembly 4 to move in tandem; when the first moving member 21 moves to the first preset position in the second direction, the first locking hook 42 rotates and separates from the first through groove 2a (see...). Figure 6 or Figure 7 , Figure 6 This refers to the state of the first locking hook 42 and the first through groove 2a when the first locking member 3 moves to the first preset position. Figure 7 The state of the first locking hook 42 and the first through groove 2a when the first locking member 3 moves to the second preset position, so as to separate the drive assembly 2 and the clutch assembly 4. The rotation setting of the first locking hook 42 can realize separation or engagement with the first through groove 2a so that the first locking hook 42 is linked or separated from the first moving member 21. The strip through groove 1a provides a space for the first locking hook 42 to engage with or disengage from the first through groove 2a when it rotates.

[0078] See Figures 7-8 Furthermore, the first moving member 21 has a second through groove 3a on one side of the first through groove 2a along its moving direction. The slider 43 and the first locking hook 42 are both placed in the second through groove 3a. When the first moving member 21 moves along the first direction, the second through groove 3a near the side wall of the first through groove 2a (referred to as the first side wall 3a1, the same below) can push the slider 43 to move. The front end of the first locking hook 42 has a beveled surface 421. The front end is the end of the first locking hook 42 that cooperates with the first through groove 2a. The clutch assembly 4 also includes a first elastic member 44 provided on the base plate 41. The first elastic member 44 provides a preload force to the first locking hook 42 to keep it horizontal. When the first moving member 21 moves along the first direction to the first preset position, the side wall of the second through groove 3a (i.e., the first side wall 3a1) The first locking hook 42 is moved along the inclined surface 421 to provide a direction perpendicular to the horizontal to overcome the force of the first elastic member 44 and rotate. At the same time, during the movement of the first moving member 21, the first side wall 3a1 also pushes the slider 43 to move. When the first locking hook 42 is located below the first through groove 2a, the restoring force of the first elastic member 44 causes the first locking hook 42 to engage with the first through groove 2a. When the first moving member 21 moves along the second direction to the first preset position, the side wall of the strip through groove 1a (i.e., the side wall on the same side as the first side wall 3a1, which is called the second side wall 2a1, hereinafter the same) moves along the inclined surface 421 to provide a direction perpendicular to the horizontal to overcome the force of the first elastic member 44 and rotate, so that the first locking hook 42 disengages from the first through groove 2a.

[0079] See Figure 8Furthermore, the drive assembly 2 also includes a first mounting base 22, a gear 23, and a handle 24. The first mounting base 22 is fixed to the bottom edge of the window frame 20. The first moving member 21 is movably mounted on the first mounting base 22. The first moving member 21 is provided with a plurality of limiting parts 211 spaced apart along the moving direction of the first moving member 21. The gear 23 is rotatably mounted on the first mounting base 22 and cooperates with at least two limiting parts 211. The limiting parts 211 can be through slots opened on the first moving member 21. When the gear 23 rotates, it drives the first moving member 21 to move through the limiting parts 211. The handle 24 is located on the inner side of the bottom edge of the window frame 20 and is connected to the gear 23. The handle 24 and the gear 23 can be connected by a square shaft. By rotating the handle 24, the gear 23 can be driven to rotate.

[0080] See Figure 6 Specifically, a groove 4a can be provided on the bottom edge of the first mounting base 22 or the window frame 20 for the first moving part 21 to pass through. The groove 4a can guide the first moving part 21 during movement, improve the stability of the first moving part 21 driving the first locking part 3 during movement, and at the same time improve the installation stability of the first locking part 3.

[0081] Example 2

[0082] See Figure 9 Furthermore, the drive assembly 2 includes a second moving member 25 and a third moving member 26 located at the bottom edge of the window frame 20 and movable along the length of the bottom edge of the window frame 20. A first locking member 3 is located on the third moving member 26. The clutch assembly 4 includes a first locking hook 42 movably located on the second moving member 25. The first locking hook 42 is connected to the linkage assembly 1. When the third moving member 26 moves to the first preset position in the first direction, the third moving member 26 can cooperate with the first locking hook 42 to make the drive assembly 2 and the clutch assembly 4 linked together so that the linkage assembly 1 can be driven by the clutch assembly 4 to control the opening or closing of the window sash 30. When the third moving member 26 moves to the first preset position in the second direction opposite to the first direction, the first moving member 21 separates from the locking hook so that the drive assembly 2 and the clutch assembly 4 separate so that when the window sash 30 is closed on the window frame 20, the drive assembly 2 can independently drive the first locking member 3 to move without interference from the linkage assembly 1 to realize the subsequent locking or unlocking action of the window sash 30.

[0083] See Figures 9-11The third moving member 26 is arranged parallel to and above the second moving member 25. The second moving member 25 has a strip-shaped through groove 1a that extends along the moving direction of the second moving member 25. The clutch assembly 4 also includes a slider 43 that is slidably disposed in the strip-shaped through groove 1a. The first locking hook 42 is rotatably disposed on the slider 43 in a direction perpendicular to the horizontal direction. The connecting rod assembly 1 is connected to the first locking hook 42 through the slider 43, that is, the second connecting rod 12 of the connecting rod assembly 1 is connected to the slider 43, so that the slider 43, the first locking hook 42, and the connecting rod assembly 1 form a whole. The third moving member 26 has a first through groove 2a. When the third moving member 26 moves to the first preset position in the first direction, the first locking hook 42 rotates and engages with the first through groove 2a to make the drive assembly 2 and the clutch assembly 4 linked together (see Figure 9 When the third moving member 26 moves to the first preset position in the second direction, the first locking hook 42 rotates and separates from the first through groove 2a, thereby disengaging the drive assembly 2 from the clutch assembly 4 (see...). Figure 10 or Figure 11 , Figure 10 The state of the first locking hook 42 and the first through groove 2a when the first locking member 3 moves to the first preset position. Figure 11 (This refers to the state of the first locking hook 42 and the first through groove 2a when the first locking member 3 moves to the second preset position). The rotation setting of the first locking hook 42 can realize separation or engagement with the first through groove 2a so that the first locking hook 42 can be linked or separated from the first moving member 21. The strip through groove 1a provides a space for the first locking hook 42 to engage with or disengage from the first through groove 2a when it rotates.

[0084] See Figures 11-12Furthermore, the bottom of the second moving member 25 is provided with a blocking member 9, one end of which extends into the strip-shaped through groove 1a. The third moving member 26 is provided with a second through groove 3a on one side of the first through groove 2a along its moving direction. The slider 43 and the first locking hook 42 are both placed in the second through groove 3a. When the third moving member 26 moves along the first direction, the second through groove 3a near the side wall of the first through groove 2a (referred to as the first side wall 3a1, the same below) can push the slider 43 to move. The front end of the first locking hook 42 is provided with a beveled surface 421. The clutch assembly 4 also includes a first elastic member 44 provided on the second moving member 25. The first elastic member 44 provides a preload force to the first locking hook 42 to keep it horizontal. When the third moving member 26 moves along the first direction, the second through groove 25 is provided with a second elastic member 44. The first elastic member 44 provides a preload force to the first locking hook 42 to keep it horizontal. When the device moves to the first preset position in one direction, the side wall of the second through groove 3a (i.e., the first side wall 3a1) can move along the inclined surface 421 to make the first locking hook 42 rotate. At the same time, during the movement of the third moving member 26, the first side wall 3a1 also pushes the slider 43 to move. When the first locking hook 42 is located below the first through groove 2a, the restoring force of the first elastic member 44 makes the first locking hook 42 engage with the first through groove 2a. When the third moving member 26 moves to the first preset position in the second direction, the first locking hook 42 moves to the end of the blocking part 61. When the third moving member 26 continues to move, the blocking part 9 moves along the inclined surface 421 to make the first locking hook 42 rotate, and the first locking hook 42 disengages from the first through groove 2a. Since the second moving member 25, which installs the first locking hook 42, is in a moving state, the position of the strip through groove 1a also moves at the same time as the second moving member 25 moves. Therefore, the blocking part 9 is provided to assist the first locking hook 42 in smoothly separating from the first through groove 2a.

[0085] See Figure 9 Furthermore, the outward-opening window device 10 also includes a self-locking component 8 that locks the first locking hook 42 when it separates from the third moving member 26, thereby keeping the first locking hook 42 in its current state. The self-locking component 8 enables the following to be achieved when the first locking hook 42 disengages from the first groove: Since the window sash 30 closes onto the window frame 20 simultaneously with the first locking hook 42 disengaging from the first groove, and the window sash 30 and window frame 20 are manufactured to ensure a tight seal between the window sash 30 and the window frame 20 when closed. The window sash 30 is surrounded by rubber strips. When the window sash 30 is closed on the window frame 20, the elastic force generated by the collision of the rubber strips between the window sash 30 and the window frame 20 makes the rotating connection of the first locking hook 42 prone to shaking, resulting in a clattering noise when the window sash 30 is closed. By setting the self-locking component 8, when the first locking hook 42 is disengaged from the first through groove 2a, a resisting force can be applied to the first locking hook 42 to maintain its current state, thereby preventing the first locking hook 42 from shaking and producing the above-mentioned noise, and improving the experience of closing the window.

[0086] See Figure 9Furthermore, the self-locking assembly 8 includes a second mounting base 81, a limiting member 82, a second locking hook 83, a support rod 84, and a second elastic member 85. The second mounting base 81 is fixed to the bottom edge of the window frame 20. The second locking hook 83 is rotatably mounted on the second mounting base 81. The limiting member 82 is mounted on the slider 43 and can move with the slider 43. When the third moving member 26 engages with the first locking hook and moves to the first preset position in the second direction, the limiting member 82 engages with the second locking hook 83 and drives the second locking hook 83 to rotate. One end of the support rod 84 is rotatably connected to the second locking hook 83, and the other end is movably connected to the second mounting base 81. Specifically, the second mounting base 81 is provided with a slot (not shown in the figure). One end of the support rod 84 passes into the slot and can move within the slot to ensure that when the limiting member 82 drives the second locking hook 83 to rotate, the support rod 84 is not restricted by the second mounting base 81 and cannot move with the first locking hook 42. The second elastic member 85 is mounted on the support rod 84. When the limiting member 82 is not engaged with the second locking hook 83, the second elastic member 85 is in a compressed state (see Figure 9 In this state, the space between the connection point of the support rod 84 and the first locking hook 42 and the connection point of the support rod 84 and the second mounting base 81 controls the compression of the second elastic element 85. When the limiting member 82 engages with the second locking hook 83, the second elastic element 85 is in its normal state (see...). Figure 10 When the limiting member 82 engages with the second locking hook 83, it drives the second locking hook 83 to rotate, causing the mounting point of the support rod 84 on the second locking hook 83 to also shift. The distance of the shifted mounting point increases the space, and the second elastic member 85 is released and returns to its normal state. When the limiting member 82 engages with the second locking hook 83, the restoring force of the second elastic member 85 in its normal state can provide the first locking hook 42 with a resisting force to keep it away from the first through groove 2a through the limiting member 82, so as to avoid the rebound force of the rubber strip when the window sash 30 closes to the window frame 20, which would cause the first locking hook 42 to shake and make abnormal noise. In addition, the force generated by the restoring force of the second elastic member 85 on the slider 43 can also be transmitted to the connecting rod assembly 1, thereby assisting the window sash 30 to close tightly.

[0087] See Figures 9-10 Specifically, the second locking hook 83 is provided with a limiting groove 831. During the movement of the limiting member 82 with the slider 43, the limiting member 82 is located in the limiting groove 831 and drives the second locking hook 83 to rotate.

[0088] See Figure 11 Furthermore, the drive assembly 2 also includes a first moving member 21, a first mounting base 22, a gear 23, and a handle 24. The first moving member 21 can move along the length of the bottom edge of the window frame 20 and is connected to the second moving member 25. The first moving member 21 is provided with a plurality of limiting parts spaced apart along its moving direction (the structure of the limiting part 211 is the same as that of the limiting part 211 in Embodiment 1, which can be referred to). Figure 8 The first mounting base 22 is located on the bottom edge of the window frame 20. The gear 23 is rotatably mounted on the first mounting base 22 and cooperates with at least two of the limiting parts. The limiting parts can be through slots opened on the first moving member 21. When the gear 23 rotates, it drives the first moving member 21 to move through the limiting parts, thereby driving the second moving member 25 to move. The handle 24 is located on the inner side of the bottom edge of the window frame 20 and is linked with the gear 23. The handle 24 and the gear 23 can be connected by a square shaft. By rotating the handle 24, the gear 23 can be driven to rotate.

[0089] See Figure 9 Specifically, a groove 4a can be provided on the bottom edge of the window frame 20 for the third moving part 26 to pass through. The groove 4a can guide the third moving part 26 during the movement process, improve the stability of the third moving part 26 driving the first locking part 3 during the movement process, and at the same time improve the installation stability of the first locking part 3.

[0090] In this embodiment, the first mounting base 22 and the second mounting base 81 can be configured as an integral structure, which can reduce the number of parts and simplify the installation steps.

[0091] In the above embodiments one and two, specifically, the slider 43 includes a first part (not shown in the figure) and a second part (not shown in the figure) of a split structure. The first part and the second part are located on the upper and lower sides of the base plate 41 and are connected. A groove 4a for accommodating the base plate 41 is formed between the first part and the second part, so that the slider 43 is installed on the strip groove 1a.

[0092] See Figure 13 In the above embodiments one and two, the first elastic element 44 can be a helical spring. The tail end of the first locking hook 42 is rotatably connected to the slider 43. The slider 43 is provided with a receiving groove 431 near the tail end of the first locking hook 42 to accommodate the helical spring. The receiving groove 431 provides installation space for the first elastic element 44. The tail end of the first locking hook 42 is provided with a snap-fit ​​part 422. The snap-fit ​​part 422 extends deep into the receiving groove 431 and is inserted into the helical spring from the side of the helical spring. When the first locking hook 42 is horizontally set, the elastic element is in the normal state. When the first locking hook 42 rotates in a direction perpendicular to the horizontal, the snap-fit ​​part 422 also rotates, thereby pulling the elastic element to be stretched.

[0093] See Figure 1 This invention also provides a door and window, including a window frame 20, a window sash 30, and the aforementioned outward-opening window device 10. The window sash 30 is movably mounted on the window frame 20, and the connecting rod assembly 1 of the outward-opening window device 10 is movably connected to the window sash 30 and the window frame 20 to drive the window sash 30 to open or close.

[0094] The door and window provided by the present invention can realize a series of functions such as unlocking, opening, closing and locking of window sash 30 through the operation drive component 2, which simplifies the opening and locking operation of window sash 30 and improves the user experience.

[0095] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
