Description

Technical Field

[0001] This utility model relates to the field of window technology, and more specifically, to a folding balcony window. Background Technology

[0002] A balcony is an extension of the interior of a building, a place for residents to breathe fresh air, dry clothes, and display potted plants. Its design needs to balance practicality and aesthetics. A balcony generally consists of railings, floor, ceiling, and lighting.

[0003] The existing Chinese utility model patent with authorization announcement number CN221568256U, published on August 20, 2024, discloses a folding balcony window. It can drive the power component to work through the cooperation between the traction chain and the first sprocket and the second sprocket, which can stably drive the opening and closing of the balcony window body and improve its safety performance.

[0004] However, in practice, this technology primarily involves mounting the drive motor on the left and right sides of the window sill frame. Firstly, the drive motor is relatively large; mounting it on the left and right sides of the window sill frame requires increasing the dimensions of the frame by approximately 10-20 centimeters to accommodate it. This reduces the length of the base support and the folding window itself, resulting in a smaller usable window length and impacting the user experience. Secondly, mounting the drive motor on the left and right sides of the window sill frame makes disassembly and installation difficult, hindering subsequent inspection, maintenance, and upkeep, thus presenting certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a folding balcony window, which installs the drive motor and reducer on the indoor side of the window frame instead of directly installing the drive motor and reducer on the window frame. This allows for a narrower design on both sides of the window frame, increases the length of the bottom support and the folding window, and increases the usable length of the window after installation. Moreover, it facilitates the disassembly and installation of the drive motor and reducer, making inspection, maintenance and upkeep more convenient.

[0006] The technical solution adopted in this utility model is as follows:

[0007] This application provides a folding balcony window, including a window frame, a base support, a folding window, a railing, and a pull chain. The railing is parallel to the base support, and the folding window is parallel to the window frame.

The bottom of the folding window is rotatably connected to the top of the base support, and the bottom of the base support is rotatably connected to the window frame. A mounting box is provided on the side of the window frame away from the folding window, and a drive device is provided inside the mounting box. One end of the pull chain is rotatably connected to the base support, and the other end of the pull chain is connected to the drive device.

[0008] Furthermore, in some embodiments of this utility model, the driving device includes a drive motor and a reducer fixed in the mounting box. The transmission shaft of the drive motor is connected to the power input end of the reducer, and the power output end of the reducer is provided with a drive shaft horizontally. A drive sprocket is fixedly provided on the drive shaft.

[0009] The mounting box contains a driven sprocket that rotates within it. The driven sprocket is located below the drive sprocket, and a drive chain is wound between the driven sprocket and the drive sprocket. The end of the pull chain away from the base is connected to the drive chain.

[0010] Furthermore, in some embodiments of this utility model, there are two mounting boxes arranged at intervals, and the drive shaft is embedded in the two mounting boxes respectively; each mounting box is provided with a driven sprocket, a drive sprocket and a drive chain.

[0011] Furthermore, in some embodiments of this utility model, a second tension sprocket is rotatably provided in the middle of the side wall of the window frame, and a pull chain is wound around the second tension sprocket.

[0012] Furthermore, in some embodiments of this utility model, a first tension sprocket is rotatably provided inside the mounting box. The first tension sprocket is located above the reducer and the second tension sprocket, and the pull chain is wound around the first tension sprocket.

[0013] Furthermore, in some embodiments of this utility model, the bottom of the folding window and the top of the base are rotatably connected by multiple hinges.

[0014] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0015] This utility model embodiment provides a folding balcony window, including a window frame, a base support, a folding window, a railing, and a pull chain.

[0021] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0022] Example

[0023] Please refer to Figures 1-3 This embodiment provides a folding balcony window, including a window frame 1, a base support 2, a folding window 3, a railing 4, and a pull chain 5. The railing 4 is parallel to the base support 2, and the folding window 3 is parallel to the window frame 1. One end of the railing 4 is rotatably connected to the window frame 1, and the other end of the railing 4 is rotatably connected to the top of the folding window 3. The bottom of the folding window 3 is rotatably connected to the top of the base support 2 through multiple hinges 15, and the bottom of the base support 2 is rotatably connected to the window frame 1. An installation box 6 is provided on the side of the window frame 1 away from the folding window 3. A drive device is provided in the installation box 6. One end of the pull chain 5 is rotatably connected to the base support 2, and the other end of the pull chain 5 is connected to the drive device.

[0024] In this embodiment, the window frame 1 is fixed to the window position of the balcony during installation. The window frame 1 is used to install the base support 2, folding window 3, railing 4 and pull chain 5. The balcony can be opened and closed through the synergistic action of the base support 2 and folding window 3. The base support 2 is used as the balcony floor when the balcony is formed, which can be stepped on by users. The folding window 3 is used to form a frontal safety railing, and the side railing 4 is used to cover the sides of the folding window 3.

[0025] The drive device in this embodiment includes a drive motor 7 and a reducer 8 fixed in the mounting box 6. The drive shaft of the drive motor 7 is connected to the power input end of the reducer 8. The power output end of the reducer 8 is provided with a drive shaft 9 horizontally. The drive shaft 9 is fixedly provided with a drive sprocket 10. A driven sprocket 11 is rotatably provided in the mounting box 6. The driven sprocket 11 is located below the drive sprocket 10. A drive chain 12 is wound between the driven sprocket 11 and the drive sprocket 10. The end of the pull chain 5 away from the base 2 is connected to the drive chain 12.

[0026] In this embodiment, there are two mounting boxes 6 spaced apart, with the drive shaft 9 embedded in each of the two mounting boxes 6. Each mounting box 6 is equipped with a driven sprocket 11, a drive sprocket 10, and a drive chain 12. Both drive sprockets 10 are fixed to the drive shaft 9. There are also two pull chains 5, each corresponding to one of the positions of the two mounting boxes 6. The two pull chains 5 are connected to the two drive chains 12, and can be pulled.

[0027] In actual use, when it is necessary to retract the base support 2 and the folding window 3 into the window frame 1, the drive motor 7 can be activated, such as... Figure 2 As shown, the reducer 8 drives the drive shaft 9 to rotate counterclockwise, which in turn drives the drive sprocket 10 to rotate counterclockwise. The drive sprocket 10 then moves the drive chain 12, which in turn moves the pull chain 5 downwards. This allows the pull chain 5 to pull the base support 2 upwards and into the window frame 1 for storage. When it is necessary to unfold the base support 2 and the folding window 3, the drive motor 7 simply rotates in the opposite direction, following the same principle as existing technologies.

[0028] Because this application uses two mounting boxes 6 on the side of the window frame 1 closest to the interior to install the drive motor 7, reducer 8, and other structures, instead of directly installing the drive motor 7 and reducer 8 onto the window frame 1, the left and right sides of the window frame 1 can be designed to be narrower, allowing for a longer base support 2 and folding window 3, thus increasing the usable length of the window after installation. Furthermore, it facilitates direct disassembly and installation of the drive motor and reducer from within the mounting boxes 6, making inspection, maintenance, and upkeep more convenient. Corresponding inspection ports can be provided on the mounting boxes 6 for inspecting and repairing the drive motor and reducer.

[0029] like Figures 1-3 As shown, in some embodiments, a second tension sprocket 14 is rotatably mounted in the middle of the side wall of the window frame 1, and the pull chain 5 is wound around the second tension sprocket 14. A first tension sprocket 13 is rotatably mounted inside the mounting box 6, located above the reducer 8 and the second tension sprocket 14, and the pull chain 5 is wound around the first tension sprocket 13. This invention, by setting the first tension sprocket 13 and the second tension sprocket 14, facilitates the installation and movement of the pull chain 5, making operation convenient.

[0030] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two. In this application embodiment, the limitations on relative positional relationships such as parallel, perpendicular, and aligned are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallel, perpendicular, and aligned are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.
