Description

Technical Field

[0001] The utility model relates to the technical field of production of casement-hung windows, and in particular to an anti-misoperation device for casement-hung windows. Background Art

[0002] Casement-hung windows are a general term for windows that can be opened and closed both horizontally and vertically. From the perspective of function, there are four basic forms: outward-opening top-hung, outward-opening bottom-hung, inward-opening top-hung and inward-opening bottom-hung. However, according to actual application needs, outward-opening top-hung windows and inward-opening bottom-hung windows are the two mainstream casement-hung windows on the market. Among them, outward-opening top-hung windows have two opening methods: one side rotates outward and opens inward, and the lower part rotates outward and hangs. In actual applications, they are often mistakenly called outward-opening bottom-hung windows. However, according to relevant industry standards, outward-opening top-hung windows with rotating hinges (generally part of the upper support assembly) at the upper end 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 inward and opens inward, and the upper part rotates inward and hangs. In actual applications, they are often called inward-opening tilt windows.

[0003] Its working principle can be found in the specification of the Chinese patent with the authorization announcement number CN220815265U. Figure 1 and attached Figure 2 explanation;

[0004] At present, because the casement and suspended windows have two opening modes, namely, casement and suspension, there is a problem: when the window sash is in either the casement or suspension state, if someone rotates the handle, the opening and closing control structure of the window sash may be disordered and normal opening and closing operations cannot be achieved. Professionals are required to readjust the window sash before normal use. Therefore, an anti-misoperation device is needed to solve this problem.

[0005] A Chinese patent with prior art authorization announcement number CN220815265U discloses an anti-misoperation device for a casement hung window, which enables the casement hung window to achieve the following functions by designing a linkage rod control section and a main control device that cooperate with each other: when the handle of the casement hung window is in a locked state (generally vertically downward), the linkage rod control section and the main control device do not affect each other, and the linkage rod can move freely; when the handle of the casement hung window is in an outward-opening unlocked state (generally horizontally), one of the slots of the linkage rod control section corresponds to the moving section of the moving seat of the main control device. At this time, the moving section can move in the direction of the connecting line at both ends of the moving seat, so that the window sash can be smoothly opened outward. After the window sash is opened outward (the outward-opening angle exceeds a very small limit angle), under the action of the compression spring, the moving seat moves in a direction close to the auxiliary control device, so that the moving section passes through the corresponding slot of the linkage rod control section. At this time, the linkage rod cannot move, ensuring that the handle is in the outward-opening state. The handle of the casement window is in the open state (generally vertically upward), the other slot of the linkage rod control section corresponds to the moving section of the moving seat of the main control device. At this time, the moving section can move in the direction of the line connecting the two ends of the moving seat, so the window sash can be smoothly opened. After the window sash is opened (the opening angle exceeds a very small limit angle), under the action of the compression spring, the moving seat moves in the direction close to the auxiliary control device, so that the moving section passes through the corresponding slot of the linkage rod control section. At this time, the linkage rod cannot move, ensuring that the handle cannot rotate when the window sash is in the open state, thereby realizing the anti-misoperation function. In summary, the utility model can realize the reliable anti-misoperation function of the casement window that the handle cannot rotate in the two states of outward opening and hanging, and the handle can only rotate after the window sash is completely closed. No human adjustment intervention is required, which effectively avoids the problem of confusion of the anti-misoperation function and the need for the manufacturer to send people for repair, which is time-consuming and labor-intensive and affects the normal use of the product.

[0006] Although the above patent can realize the reliable anti-misoperation function that the handle of the casement hanging window cannot be rotated in the two states of outward opening and hanging opening, and the handle can be rotated after the window sash is completely closed, and does not require human adjustment and intervention, it effectively avoids the problem that the anti-misoperation function is disordered and the manufacturer needs to send people to repair, which is time-consuming and labor-intensive and affects the normal use of the product. However, the overall structure of the device is relatively complicated, which is not conducive to cost saving.

[0007] Therefore, the applicant proposes an anti-misoperation device for a casement-hung window to solve the above problems. Utility Model Content

[0021] Compared with the prior art, the utility model provides an anti-misoperation device for a casement-hung window, which has the following beneficial effects:

[0022] 1. The utility model enables the casement hung window to achieve the following functions through the mutual cooperation of the linkage rod control section, the main control device and the auxiliary control device: when the handle of the casement hung window is in a locked state (generally vertically downward), the linkage rod control section and the main control device do not affect each other. At this time, the linkage rod can move freely, and the linkage rod control section can pass through the moving through slot freely; when the handle of the casement hung window is in an outwardly opened unlocked state (generally horizontally), one of the slots of the linkage rod control section corresponds to the slider lock body, and the slider lock body can pass through the corresponding slot, so the window sash can be smoothly opened outward. After the window sash is opened outward (the outward opening angle exceeds a very small limit angle), under the action of the spring, the slider lock body moves in a direction close to the auxiliary control device, and the slider lock body extends out of the main control box, so that the slider lock body passes through the corresponding slot of the linkage rod control section. At this time, the linkage rod cannot move, ensuring that the handle cannot rotate when the window sash is in the outwardly opened state, thereby achieving error prevention. Operation function: when the handle of the casement hanging window is in the hanging state (generally vertically upward), the other slot of the linkage rod control section corresponds to the slider lock body. At this time, the slider lock body can pass through the corresponding slot, so the window sash can be smoothly hung. After the window sash is hung (the hanging angle exceeds a very small limit angle), under the action of the spring, the slider lock body moves in the direction close to the auxiliary control device, and the slider lock body extends out of the main control box, so that the slider lock body passes through the corresponding slot of the linkage rod control section. At this time, the linkage rod cannot move, ensuring that the handle cannot be rotated when the window sash is hung, thereby realizing the anti-misoperation function; in summary, the utility model can realize the reliable anti-misoperation function of the casement hanging window that the handle cannot be rotated in the two states of outward opening and hanging, and the handle can be rotated after the window sash is completely closed. No human adjustment intervention is required, which effectively avoids the problem of confusion of the anti-misoperation function and the need for the manufacturer to send people for repair, which is time-consuming and labor-intensive and affects the normal use of the product.

[0023] 2. All components of the utility model can be installed on the hinged end of the casement window. When the casement window is in the open state, its opening angle is small. The components of the utility model are relatively hidden and cannot be touched by people outside. Especially when used for outward-opening top-hung windows, the components of the utility model will not be controlled by people outside. Therefore, people outside cannot achieve the purpose of opening the window sash horizontally when it is suspended by controlling the components of the utility model, thereby achieving a reliable anti-theft function.

[0024] 3. Compared with the prior art, the overall structure of the utility model is simpler, which effectively reduces the production cost, is more economical, and is more convenient to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The utility model provides an anti-misoperation device for a casement-hung window, referring to Figures 1 to 10 , comprising: a linkage rod 1, a main control device 2 and an auxiliary control device 3;

[0042] Reference Fig.10 The linkage rod 1 is installed on the sash of the casement window and connected to the handle of the casement window through a transmission device. The middle section of the linkage rod 1 is provided with a linkage rod control section 4. The linkage rod control section 4 can move in the axial direction of the linkage rod 1. The linkage rod control section 4 is provided with a first card slot 5 and a second card slot 6 arranged in an axial direction of the linkage rod 1 at intervals. The first card slot 5 and the second card slot 6 are respectively passed through the linkage rod 1 in the radial direction.

[0043] Among them, refer to Fig.10In this embodiment, connecting racks 7 are provided at both ends of the linkage rod 1, which is a conventional adaptive structure.

[0044] Specifically, one end of the linkage rod 1 is connected to the transmission device through the connecting rack 7, thereby realizing a transmission connection with the handle.

[0045] Reference Figures 7 to 9 The main control device 2 is installed on the sash of the casement window. The main control device 2 includes a main control box 21. A movable groove 22 is provided at one end of the main control box 21. A slider lock body 23 is slidably provided in the movable groove 22. The sliding direction of the slider lock body 23 is perpendicular to the axial direction of the linkage rod 1. A spring 24 is connected between one end of the slider lock body 23 and the inner wall of the movable groove 22 to provide elastic force for the slider lock body 23 to extend out of the main control box 21. The other end of the slider lock body 23 can extend out of the main control box 21. A movable through groove 25 is provided on the slider lock body 23 for the linkage rod control section 4 to pass through.

[0046] Specifically, the movable groove 22 passes through the top of the main control box 21; screw holes are opened on both sides of the movable groove 22 on the main control box 21, and the main control box 21 is installed on the window sash of the casement window by fixing screws; the slider lock body 23 is in an inverted concave shape, and the movable through groove 25 passes through in a direction parallel to the axial direction of the linkage rod 1, and the axial width of the slider lock body 23 in the linkage rod 1 is smaller than the width of the first card slot 5 and the width of the second card slot 6.

[0047] Among them, refer to Figure 4 In this embodiment, a main control box through slot 26 is provided on the main control box 21 for the linkage rod control section 4 to pass through, and the linkage rod 1 is located below the main control box 21 .

[0048] Specifically, the width of the movable through slot 25 in the sliding direction of the slider lock body 23 is the same as the width of the main control box through slot 26 .

[0049] Reference Figure 8 In this embodiment, one side of the main control box slot 26 is connected to the movable slot 22, and the other side of the main control box slot 26 is connected to the slider lock body slot 27, and the slider lock body 23 can extend out of the main control box 21 through the slider lock body slot 27.

[0050] Specifically, one side of the main control box through slot 26 is connected to the lower part of the movable slot 22; the slider lock body through slot 27 corresponds to the lower part of the movable slot 22, which facilitates the sliding of the slider lock body 23; when the slider lock body 23 does not extend out of the slider lock body through slot 27, the movable through slot 25 coincides with the main control box through slot 26, which facilitates the free movement of the linkage rod control section 4.

[0051] Reference Figure 7In this embodiment, a spring base 28 is provided in the movable groove 22 , a spring connecting groove 29 is provided on one end of the slider lock body 23 facing the movable groove 22 , and the spring 24 is connected between the spring base 28 and the spring connecting groove 29 .

[0052] Specifically, a fixing column is provided in the spring connection groove 29 , the spring 24 is connected between the spring base 28 and the fixing column, and the spring 24 is sleeved outside the fixing column, so that the adjustment of the slider lock body 23 by the spring 24 is more stable and reliable.

[0053] Preferably, the linkage rod 1 and the main control device 2 are both installed on the upper outer wall of the window sash of the outward-opening and top-hung window, the linkage rod 1 is located below the main control device 2, and one end of the linkage rod 1 is connected to the transmission device through the connecting rack 7, thereby realizing a transmission connection with the handle; when the window sash is closed, the slider lock body 23 can be resisted and retracted by the window frame or the corresponding component installed on the window frame; when the window sash is opened horizontally or hung, the slider lock body 23 can extend out of the main control box 21.

[0054] Reference Figure 5 and Figure 6 The auxiliary control device 3 is installed on the window frame of the casement window, and the auxiliary control device 3 includes an auxiliary control box 31. A block placement groove 32 is provided on the auxiliary control box 31. A first opening 34 connected to the block placement groove 32 is provided on the side of the auxiliary control box 31 facing the main control device 2. A block 33 is slidably provided in the block placement groove 32. An arc-shaped protrusion 8 located in the first opening 34 is installed on the block 33, and the arc-shaped protrusion 8 corresponds to one end of the slider lock body 23 that can extend out of the main control box 21.

[0055] Specifically, the top of the block placement groove 32 and the first opening 34 both pass through the top of the auxiliary control box 31, and the side of the block placement groove 32 close to the first opening 34 and the first opening 34 both pass through the bottom of the auxiliary control box 31; preferably, the side of the slider lock body 23 facing the arc-shaped protrusion 8 is also arranged in an arc shape, and the apex of the arc-shaped protrusion 8 is just flush with the side wall of the auxiliary control box 31, and the block 33 can move up and down in the block placement groove 32, and the block 33 is adjusted by the height of the slider lock body 23, thereby driving the arc-shaped protrusion 8 to move, so that the arc-shaped protrusion 8 can block or resist the slider lock body 23, and when the handle of the casement hanging window is in a locked state, the arc-shaped protrusion 8 resists the slider lock body 23, so that the slider lock body 23 can just not extend out of the slider lock body through groove 27; the auxiliary control device 3 is installed on the upper inner wall of the window frame of the casement hanging window.

[0056] Reference Figure 4When the arc-shaped protrusion 8 is pressed against the slider lock body 23, the condition for the slider lock body 23 to just not extend out of the slider lock body through groove 27 is that the vertex of the arc-shaped protrusion 8 is in line contact with the vertex of the slider lock body 23 (that is, the side of the slider lock body 23 facing the arc-shaped protrusion 8 is also arranged in an arc shape). In the process of hanging, the arc-shaped protrusion 8 and the slider lock body 23 will be misaligned. The side of the stopper placement groove 32 close to the first opening 34 and the first opening 34 are arranged to penetrate the bottom of the auxiliary control box 31, so that the slider lock body 23 can It can better pass through the bottom of the auxiliary control box 31, so that the slider lock body 23 can extend a little more out of the slider lock body slot 27 when it is misplaced, so that the length of the slider lock body 23 passing through the corresponding slot of the linkage rod control section 4 is increased to achieve a more reliable locking function, and prevent the linkage rod 1 from being driven to move when the handle is rotated forcefully due to the window sash being hung too small and the overlapping length of the corresponding slot of the slider lock body 23 and the linkage rod control section 4 being too small, thereby losing the anti-misoperation function and possibly damaging the corresponding components.

[0057] Another situation is that when the handle of the casement window is in a locked state, the arc-shaped protrusion 8 presses against the slider lock body 23. If the slider lock body 23 can extend a portion of the slider lock body slot 27, and the movable slot 25 and the main control box slot 26 are still in an overlapping state, if it is to prevent the overlapping portion of the slider lock body 23 and the corresponding slot of the linkage rod control section 4 from being too short due to the small opening angle of the window sash, and the linkage rod 1 can be driven to move when the handle is rotated forcefully, the upper part of the arc-shaped surface of the slider lock body 23 needs to be in line contact with the lower part of the arc-shaped protrusion 8 to meet the condition.

[0058] Reference Figure 5 and Figure 6 In this embodiment, the auxiliary control box 31 is provided with sliding grooves 35 on both sides of the block placement groove 32, and a slide plate 36 is slidably provided in the sliding groove 35, and a positioning screw 37 is threadedly connected to the slide plate 36.

[0059] Specifically, the top of the slide groove 35 passes through the top of the auxiliary control box 31; the position of the stopper 33 is fixed by a positioning screw 37; preferably, the slide groove 35 is T-shaped.

[0060] Among them, refer to Figure 5 and Figure 6 In this embodiment, second openings 38 communicating with the slide slots 35 are provided on both sides of the auxiliary control box 31 to facilitate installation of the positioning screws 37 .

[0061] Specifically, the stopper 33 is placed in the stopper placement groove 32 , and the slide plate 36 is placed in the slide groove 35 . After adjusting the heights of the stopper 33 and the slide plate 36 , the positioning screw 37 is installed from the second opening 38 to fix the position of the stopper 33 .

[0062] Reference Figures 1 to 6 In this embodiment, an auxiliary control box mounting plate 39 is provided on the top of the auxiliary control box 31 .

[0063] Specifically, the tops of the block placement groove 32, the first opening 34 and the slide groove 35 all pass through the top of the auxiliary control box mounting plate 39, which facilitates the installation of the block 33, the arc-shaped protrusion 8 and the slide plate 36; screw holes are provided on the auxiliary control box mounting plate 39, and the auxiliary control device 3 is installed on the window frame of the casement window by fixing the screws.

[0064] Working principle: When the window sash is in the closed state, the slider lock body 23 is held against by the arc-shaped protrusion 8 on the stopper 33, so that the slider lock body 23 can just not extend out of the slider lock body slot 27. At this time, the movable slot 25 is correspondingly connected with the slot 26 of the main control box, and the linkage rod control section 4 can slide in the movable slot 25. This device does not limit the position of the linkage rod 1, and the handle can be rotated as needed; if the user wants to lock the window sash, the handle is rotated downward to make it vertically downward, and the window sash cannot be opened at this time; if the user wants to open the window sash outward, the handle is rotated upward to make it horizontal, and at this time the first card slot 5 on the linkage rod control section 4 (or the second slot 6) just corresponds to the slider lock body 23, the slider lock body 23 can move relative to the linkage rod 1, at this time the user can open the window sash outward; after the window sash is opened outward (the outward opening angle exceeds a very small limit angle), under the action of the spring 24, the slider lock body 23 moves in the direction close to the auxiliary control device 3, the slider lock body 23 extends out of the main control box 21, so that the slider lock body 23 passes through the corresponding slot of the linkage rod control section 4, at this time the linkage rod 1 can no longer move axially, thereby ensuring that the handle cannot be rotated when the window sash is in the outward opening state (rotation in any direction cannot be achieved), thereby realizing the anti-misoperation function.

[0065] If the handle is to be rotated, the window sash needs to be closed first, and the slider lock body 23 is again held by the arc-shaped protrusion 8 on the stopper 33, and the handle 2 can be rotated upward or downward as needed.

[0066] If the user wants to suspend the window sash, the handle is rotated upward to make it in a vertical upward state. At this time, the second slot 6 (or the first slot 5) of the linkage rod control section 4 just corresponds to the slider lock body 23. At this time, the slider lock body 23 can move relative to the linkage rod 1, and the user can rotate the lower end of the window sash outward to open it, that is, suspend it; after the window sash is suspended (the suspension angle exceeds a very small limit angle), under the action of the spring 24, the slider lock body 23 moves in the direction close to the auxiliary control device 3, and the slider lock body 23 extends out of the main control box 21, so that the slider lock body 23 passes through the corresponding slot of the linkage rod control section 4. At this time, the linkage rod 1 can no longer move axially, thereby ensuring that the handle cannot be rotated when the window sash is in the outward opening state (rotation in any direction cannot be achieved), thereby realizing the anti-misoperation function; in this state, people outside cannot control the components of the utility model, so the locked state cannot be released, and the window sash cannot be opened outward while suspended by rotating the handle, thereby realizing the anti-theft function.

[0067] If the handle is to be able to rotate downward, the window sash needs to be closed first, and the slider lock body 23 is again held by the arc-shaped protrusion 8 on the stopper 33. At this time, the handle can be rotated downward to return to the desired position for opening outward or locking.
