Technical Field

[0001] This application relates to the field of building safety technology, specifically to a window screen assembly. Background Technology

[0002] Currently, window screens have become an essential accessory in modern homes due to their functions of windproofing, dustproofing, and insect prevention. A common type of window screen consists of a screen attached to a fixed window frame, which must be used in conjunction with a glass window. However, people may forget to close the screen after the window is open, allowing flies and other insects to enter the room. This is especially problematic in households with young children, whose lower immune systems make them more susceptible to illnesses caused by flies and other insects. Furthermore, the lack of safety measures when the window is open increases the risk of accidental objects being thrown from heights or children accidentally falling.

[0003] Therefore, existing window screens need to be improved so that they can automatically close when the window is opened. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a screen window assembly that, by changing the structure of existing screen windows and windows, solves the problem of flies and insects entering the room and spreading infection when the screen window is left open after the window is opened.

[0005] The screen window assembly provided in this application adopts the following technical solution:

[0006] A screen window assembly includes a screen window body installed in a window frame and a limiting component for restricting the movement of the screen window body. The screen window body has a support column protruding inwards. The limiting component can limit the support column on the screen window body and keep the screen window body in a suspended state. When the window is opened, the screen window automatically closes by driving the limiting component away from the support column on the screen window body.

[0007] Furthermore, it also includes a fixing rod assembly disposed between the window frame and the window sash for driving the limiting component, wherein one end of the fixing rod assembly is connected to the window sash and the other end is connected to the limiting component.

[0008] Furthermore, the fixing rod assembly includes a sleeve and a fixing rod, the fixing rod being movable along its length within the sleeve.

[0009] Furthermore, an elastic element is provided between the end of the fixing rod near the window frame and the end of the sleeve near the window frame, and the elastic element is located inside the sleeve.

[0010] Furthermore, the two ends of the fixing rod are respectively connected to the window sash and the elastic element, and the end of the sleeve near the window frame is hinged to the limiting component.

[0011] Furthermore, the fixing rod is evenly provided with a number of elastic buckles in the length direction, and the sleeve is correspondingly arranged with a number of through holes connected to the elastic buckles in the length direction.

[0012] Furthermore, the limiting component is disposed in the groove of the opposite side frame of the window frame away from the connection between the window sash and the window frame.

[0013] Furthermore, the limiting component includes a sliding member disposed at the bottom of the window frame and a buckle for limiting the support column on the screen body, the buckle being hinged within the window frame.

[0014] Furthermore, a pull rope is provided between the slider and the buckle, the pull rope being used to connect the slider and the buckle and to transmit tension to the buckle.

[0015] Furthermore, the top of the sliding member is provided with a connecting part, which is used to hinge with the sleeve of the fixed rod assembly.

[0016] In summary, this application has at least one of the following beneficial effects: the screen window assembly provided by this application can automatically close the screen window when the window is opened, avoiding the safety problems of accidental high-altitude throwing and falling objects, and can also prevent mosquitoes and other insects from entering the room, ensuring safety while ensuring indoor and outdoor air circulation.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] A screen window assembly includes a screen window body installed in a window frame 2 and a limiting component for restricting the movement of the screen window body. The screen window body has a support column 11 protruding inward. The limiting component can limit the support column 11 on the screen window body and keep the screen window body in a suspended state. When the window is opened, the screen window can automatically close by driving the limiting component away from the support column on the screen window body.

[0027] like Figure 1 As shown, the window in this embodiment is a traditional outward-opening single-sash window, which does not occupy indoor space when open; the screen is a framed screen, which can be a single screen or multiple small screens arranged vertically. This embodiment uses a combination of a fixed lower screen and a movable upper screen. The lower screen is fixed to the window frame and does not open; the upper screen 10 can move up and down within the tracks formed by the side frames of the window frame 2; a support column 11 protrudes from the side frame of the upper screen 10 away from the connection between the window sash and the window frame, pointing inward; the support column 11 is located in the upper middle part of the side frame, and the specific position can be determined according to the usage; when the window is closed, the support column 11 is limited by the limiting component, so that the upper screen 10 is in a suspended state, and the upper end of the screen is hidden in the receiving groove opened between the top of the window frame and the wall. When the window is opened to a certain angle, the limiting component disengages from the support column 11, the upper screen 10 loses support, and falls directly to the lower screen to close under the influence of gravity.

[0028] In this embodiment, a fixing rod assembly is also included, which is disposed between the window frame 2 and the window sash 1 for driving the limiting component. One end of the fixing rod assembly is connected to the window sash 1, and the other end is connected to the limiting component.

[0029] Combination Figure 3As shown, the left end of the window sash 1 and the left end of the window frame 2 are respectively hinged and rotated by elastic hinges 14. The elastic hinges are in a compressed state when the window is closed, so that the window can provide a certain initial elastic force to the window sash 1 when it is first opened, thereby increasing the opening angle of the window sash. A telescopic fixed rod assembly is installed between the window sash and the window frame. The end of the fixed rod assembly away from the window frame is hinged to a connector fixedly installed at the top or bottom of the window sash, allowing it to rotate around the connector as the window sash opens. The other end of the fixed rod assembly is directly hinged to a limiting assembly installed inside the window frame. The fixed rod assembly can also limit the rotation angle of the window sash when it is opened. The type of fixed rod assembly is not fixed, but it must meet the function of telescopic movement. It can be an electric telescopic rod, a pneumatic telescopic rod, or an elastic telescopic rod assembled from multiple sleeves, inner rods, and elastic elements, etc., which can be selected according to the application.

[0030] In this embodiment, the fixing rod assembly includes a sleeve 4 and a fixing rod 3. The fixing rod 3 can move along the length direction within the sleeve 4. An elastic element is provided between the end of the fixing rod 3 near the window frame 2 and the end of the sleeve 4 near the window frame 2. The elastic element is located inside the sleeve 4.

[0031] Combination Figure 3 and Figure 6 As shown, the fixing rod 3 is mainly a metal rod with a certain rigidity and strength, and its shape includes but is not limited to cylindrical, square, etc.; while the sleeve 4 is a metal tube with an internal cavity. The shape of the cavity needs to be consistent with the shape of the fixing rod 3 and larger than the outer dimensions of the fixing rod, so as to facilitate the movement and accommodation of the fixing rod 3 in the sleeve; the elastic component is an elastic part with elasticity. In this embodiment, it is mainly a spring 12. The spring 12 is installed inside the sleeve. One end of the spring 12 is connected and fixed to the fixing rod 3, and the other end is connected to the end of the sleeve 4 near the window frame 2. The spring 12 is in a compressed state when the window is closed, and can provide a certain elastic force to the window sash 2 when the window is open. Therefore, the size and length of the spring are mainly selected and determined according to the fact that the fixing rod assembly needs to be able to meet the pulling force of pushing the window sash when it is extended and to ensure that the spring will not fail under the ultimate tension state within the safety threshold.

[0032] In this embodiment, combined with Figure 6 and Figure 7As shown, the fixing rod 3 is a rectangular metal rod, while the sleeve 4 is a metal tube with an opening at the bottom. The end of the fixing rod 3 near the window sash 1 is hinged to a connector fixedly installed at the top or bottom of the window sash 1. The other end of the fixing rod 3 is connected to a spring inside the sleeve 4, so that the fixing rod can move within the sleeve 4 as the window sash 1 opens and closes under the action of the spring force. The end of the sleeve 4 where the spring 12 is installed is also directly hinged to the limiting component, so that the sleeve 4 can rotate according to the displacement change of the limiting component within the window frame, thereby realizing the opening and closing of the window sash.

[0033] In this embodiment, the fixing rod 3 is uniformly provided with a plurality of elastic buckles 5 along its length, and the sleeve 4 is provided with a plurality of through holes connected to the elastic buckles along its length. When the window is closed normally, the elastic buckles 5 are in the extended state and embedded in the through holes on the sleeve, so that the fixing rod 3 is stuck in the sleeve and does not move. When the window is opened, the window sash 2 can rotate outward by the initial elastic force provided by the elastic hinge 14 and the spring 12. At this time, the initial elastic force needs to be greater than the pulling force that limits the elastic buckle 5 after it enters the through hole, until the elastic force of the spring 12 and the elastic hinge 14 and the pulling force of the elastic buckle 5 are in a static equilibrium state, and the window sash stops rotating. After the window sash stops rotating, the user can also manually press the elastic buckle 5 to retract it out of the through hole of the sleeve 4 and adjust the opening angle of the window sash 2 according to the usage requirements.

[0034] In this embodiment, the limiting component is disposed in the groove of the opposite side frame of the window frame away from the connection between the window sash 1 and the window frame 2; the limiting component includes a sliding member disposed in the bottom of the window frame and a buckle 13 for limiting the support column on the screen body, the buckle 13 being hinged in the window frame 2; a pull rope 7 is disposed between the sliding member and the buckle 13, the pull rope 7 being used to connect the sliding member and the buckle 13 and to transmit tension to the buckle.

[0035] Combination Figure 1 and Figure 2As shown, the limiting components are mainly set in the receiving groove on the right side of the window frame 2. By slotting the frame, the limiting components are all arranged inside the window frame, which will not affect the appearance of the window. At the same time, the size of the slot only needs to be sufficient to accommodate the installation of the buckle 13 and not affect the use of the pull rope 7. It can be selected according to the specific use. The slot in this embodiment is only an example. The front end of the buckle 13 is hook-shaped, the rear end is fastened to the pull rope 7, and the middle section is hinged and fixed to the window frame inside the window frame 2. It is necessary to ensure that the front end of the buckle 13 can automatically droop down when not affected by external force. When the window is closed, it is at a 9-degree angle with the pull rope. 0°, its main function is to hook onto the support post 11 on the upper screen window 10, so that the upper screen window 10 is in a suspended state; when the window is opened, the fixing rod assembly pulls the sliding part to the left, the sliding part then moves the pull rope 7, the pull rope 7 pulls the buckle 13 to generate a lever movement at the buckle hinge point, thereby gradually increasing the angle between the buckle 13 and the pull until the buckle 13 slides off the support post 11, and the upper screen window 10 falls down and closes; when the window is closed, the screen window is opened first, and the window sash and window frame are pulled back. The buckle is not affected by other external forces, and under the action of gravity, the front end hangs down and locks onto the support post 11.

[0036] Combined Figure 4 and Figure 5 As shown, a slide rail 8 is arranged along the length of the top or bottom of the window frame 2. The sliding component is mainly used to connect the sliding block 6 of the fixing rod assembly. A pull rope 7 is connected to the right end of the sliding block 6. The sliding block 6 is connected to the buckle 13 through the pull rope 7. A rotation point is set near the end of the slide rail 8 to change the direction of the pull rope 7, so as to realize the transformation of the pull rope 7 from horizontal displacement to vertical displacement. The slide rail 8 has a convex structure that is narrower at the top and wider at the bottom, mainly to limit the displacement of the sliding block 6 in the height direction and prevent the sliding block from flying out of the slide rail 8. The bottom of the slide rail has a certain degree of smoothness, mainly to reduce the friction of the sliding block 6 when it moves in the slide rail 8.

[0037] In this embodiment, combined with Figure 3 and Figure 4 As shown, the top of the sliding block 6 is provided with a connecting part, which is used to hinge with the sleeve of the fixed rod assembly; the connecting part is mainly a connecting post 9 for hinged with the sleeve 4 on the fixed rod assembly. Through the connecting post 9, the sliding block 6 can also move along with the slide rail 8 when the fixed rod assembly rotates with the window sash.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application, and all such modifications or substitutions should be covered within the scope of the claims of this application.
