[0001] The utility model relates to a split window technical field. BACKGROUND

[0002] Split windows are designed with false mullions for aesthetics and functionality, which can provide similar decorative effects as ordinary mullions when the window is closed, are not limited by the size of the window body, are convenient for construction, and have sound insulation, waterproof, and dustproof functions.

[0003] Existing split windows include active and passive fans, and the false mullion is usually connected to the frame profile of the active or passive fan, which increases the width of the frame on one side of the active or passive fan. After closing the window, the width of the middle profile increases, affecting the overall aesthetics, reducing the area of the glass, and reducing the light transmittance. SUMMARY

[0004] To solve the above problems of the prior art, the utility model provides a split window, which directly uses a false mullion as a side frame, which can serve as a frame and also retains the structure of the false mullion, saving materials and reducing the width of the middle profile, making the overall more aesthetically pleasing and better for light transmittance.

[0005] The technical scheme adopted is as follows:

[0006] A split window includes a window frame, an active fan and a passive fan arranged in the window frame, a false mullion arranged between the active fan and the passive fan, the false mullion directly serving as a side frame of the active fan or the passive fan, and the side frame being arranged at the connection between the active fan and the passive fan.

[0007] Further, the passive fan includes a passive fan frame, and the passive fan frame includes an upper fan frame and a lower fan frame.

[0008] Further, the false mullion directly serves as a side frame of the passive fan on the side close to the active fan, and connects the upper fan frame and the lower fan frame.

[0009] Further, at least one connecting piece is arranged between the false mullion and the upper fan frame, and at least one connecting piece is arranged between the false mullion and the lower fan frame.

[0010] Further, a connecting groove is arranged on the false mullion, and a connecting block matched with the connecting groove is arranged on the connecting piece.

[0011] Further, the connecting piece has two.

[0012] Further, the false mullion includes an upper profile and a lower profile.

[0013] Furthermore, the upper frame is provided with a first mounting block extending in the direction of the passive sash for mounting glass, and the connection between the first mounting block and the upper and lower sash frames is provided with a chamfer.

[0014] Furthermore, the upper frame is provided with an extension plate extending in the direction of the active fan for connecting the active fan.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention provides a double-leaf window with a false center mullion structure, which directly serves as the frame of one side of the active or passive sash. Compared to existing technologies that connect the false center mullion to the sash frame, this invention eliminates part of the sash frame structure and the connecting piece between the false center mullion and the sash frame, resulting in a narrower sash frame width, saving materials and reducing costs. The narrower central profile increases the glass area and improves light transmission. The false center mullion, as a side sash frame, is connected to the upper and lower sash frames via connectors, making it easy to manufacture, disassemble, and install. Attached Figure Description

DETAILED DESCRIPTION

[0026] The utility model will be further described below in combination with specific embodiments.

[0027] Reference Figures 1-7 A split window, comprising a window frame, a driving fan 1 and a passive fan 2 arranged in the window frame, a false mullion 3 arranged between the driving fan 1 and the passive fan 2, the false mullion 3 directly serving as a side sash frame on one side of the driving fan or the passive fan, and the side sash frame being arranged at the connection between the driving fan and the passive fan.

[0028] The passive fan 2 comprises a passive fan frame 4, and the passive fan frame 4 comprises an upper sash frame 401 and a lower sash frame 402.

[0029] At least one connecting piece 5 is arranged between the false mullion 3 and the upper sash frame 401 and between the false mullion 3 and the lower sash frame 402. The false mullion 3 is provided with a connecting clamping groove 6, and the connecting piece 5 is provided with a connecting clamping block 501 matched with the connecting clamping groove. Preferably, two connecting pieces 5 are arranged. One end of the connecting piece 5 is inserted into the hollow profile of the upper sash frame and the lower sash frame, and the other end is connected to the false mullion 3 through the connecting clamping block 501. In order to facilitate installation, the upper and lower end faces of the false mullion 3 need to be end-milled to form a flat surface during processing. After installation, end covers need to be arranged on the upper and lower ends to block the hollow structure of the false mullion 3, so that the overall structure is more stable, and the effect of beauty and dust prevention can also be achieved. The connecting piece 5 is clamped with the false mullion 3, and the installation and disassembly are convenient.

[0030] The false mullion 3 comprises an upper profile frame 301 and a lower profile frame 302. The upper profile frame 301 is provided with a first mounting block 7 extending towards the passive fan 2 and used for mounting a glass 11, and a chamfer 8 is arranged at the connection between the first mounting block 7 and the upper and lower sash frames. The first mounting block 7 is arranged to facilitate the installation of the glass on the passive fan 2. In order to prevent the extended first mounting block 7 from interfering with the upper and lower sash frames, a chamfer 8 needs to be arranged at the connection between the first mounting block 7 and the upper and lower sash frames, and the chamfer 8 is in close contact with the edges of the upper and lower sash frames.

[0031] The upper mold frame 301 is provided with an extension plate 9 extending to the direction of the active fan 1 and used for connecting the active fan 1. The lower mold frame 302 is connected with a second mounting block 10 used for mounting the glass 11 near the passive fan side, and the lower mold frame 302 is provided with a mounting groove 12 matched with the second mounting block 10. The second mounting block 10 is directly mounted on the false centering 3 through the mounting groove 12. The glass 11 is arranged between the first and second mounting blocks, and a rubber strip is further arranged between the glass and the first and second mounting blocks. The false centering 3 can meet the requirements of the fan frame and the false centering, and seal the gap between the active fan and the passive fan.

[0032] The upper and lower plugs are fixed by screws and are stable and not easy to fall off.

[0033] In the existing split window, the false centering is arranged on the fan frame of any one of the active fan and the passive fan, and the width of the fan material profile provided with the false centering is the sum of the width of the fan frame and the width of the false centering. In addition, a connecting structure is arranged between the false centering and the fan frame for connection. The false centering is directly used as the side fan frame in the utility model, so the width of the fan material profile is the width of the false centering. Compared with the prior art, the utility model is more material-saving, has lower cost, and has smaller width of the middle profile. The area of the glass arranged on the two fans can be larger, the light transmission effect is better, and the utility model is more beautiful.

[0034] In the embodiment, the false centering is used as the side fan frame of the passive fan. The structure is also applicable to the active fan, and will not be described here again. When being opened, the active fan is opened first, and then the passive fan is opened. When being closed, the active fan is closed first, and then the passive fan is closed. The opening mode is the same as that of the prior art.

[0035] The above description is only optional embodiments of the utility model, and does not limit the patent range of the utility model. Any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the utility model and the contents of the utility model specification and drawings are included in the patent protection range of the utility model.
