Description

Technical Field

[0001] The utility model relates to the technical field of casement windows, and specifically relates to a casement window that can be opened bidirectionally. Background Technique

[0002] A casement window is a common type of window. Its sash is installed on one side of the window frame through hinges and can be opened inwards or outwards. According to its opening direction and installation position, casement windows can be divided into inward casement windows and outward casement windows. A casement window that can be opened bidirectionally is usually called a "double-opening window" or "bidirectional casement window". This window design allows the sash to be opened inwards or outwards, providing greater flexibility and ventilation effect.

[0003] A patent document with the publication number CN214835742U records a casement window that can be opened bidirectionally inside and outside. The solution recorded therein enables the first window door and the second window door to achieve a double-opening effect under the action of a rotator, and the stability of the first window door and the second window door can be improved by a limiting device, thereby preventing the window door from being damaged due to external factors.

[0004] The above case has the problem that the rolling curtain cannot be stored during ventilation. When this casement window is equipped with a rolling curtain, the rolling curtain cannot be stored during ventilation. When not stored, the wind will directly drive the rolling curtain, causing the rolling curtain to collide with the window frame, which will damage both the curtain box and the window frame, and also generate noise, affecting the quietness and comfort of the room.

By rotating the rotating column 401, the first rotating gear 402 is driven to rotate, thereby driving the first rack 403 and the bending strip 404 to move up and down, and thus driving the retractable roller shutter 300 to move up and down.

[0030] In one embodiment, as Figure 1 、 Figure 2 and Figure 5 shown, the limiting component includes a sliding groove 501, the sliding groove 501 is provided in the upper middle part and the lower middle part of the window frame 100, a limiting plate 502 is slidably connected inside the sliding groove 501, locking nuts 503 are threadedly connected to both ends of one side of the limiting plate 502, and the locking nuts 503 are rotatably connected inside the sliding groove 501. By rotating the locking nuts 503, they are moved away from the limiting plate 502 and the sliding groove 501, so that the limiting plate 502 can slide inside the sliding groove 501.

[0031] In one embodiment, as Figure 3 shown, a positioning component for positioning the window door 200 is provided on the rotating column 401. The positioning component includes a second rotating gear 601, the gear shaft of the second rotating gear 601 is fixedly connected to the other end of the rotating column 401, the second rotating gear 601 meshes with a second rack 602, the second rack 602 is slidably connected in the limiting groove, and a pin block 603 is provided on the side of the second rack 602 close to the window door 200. The pin block 603 is slidably connected inside the window door 200. By rotating the rotating column 401, the second rotating gear 601 is driven to rotate, thereby driving the second rack 602 and the pin block 603 to move, so as to approach or move away from the inside of the window door 200.

[0032] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 andFigure 4 As shown, a fixing assembly for fixing the rotating column 401 is further provided on the rotating column 401. The fixing assembly includes a handle 701. The handle 701 is fixedly connected to the side of the rotating column 401 away from the window frame 100. A limiting hole is provided in the middle and lower part of the window frame 100. A sliding rod 702 is slidably connected to the inner part of the lower middle end of the handle 701. The other end of the sliding rod 702 is slidably connected to the inside of the limiting hole. A grip 703 is provided on the sliding rod 702. A spring is provided between the grip 703 and the handle 701. By pulling the grip 703, the sliding rod 702 is driven to approach the handle 701, so that the sliding rod 702 disengages from the limiting hole. After canceling the pulling force on the grip 703, under the action of the spring, the sliding rod 702 will enter the limiting hole again.

[0033] In one embodiment, as Figure 1 and Figure 2 shown, one end of the lock nut 503 is hexagonal, which is convenient for rotating the lock nut 503.

[0034] In one embodiment, as Figure 1 and Figure 2 shown, rubber pads are provided on both sides of the window door 200 to increase the sealing performance.

[0035] In one embodiment, as Figure 3 shown, the first rack 403 and the second rack 602 are arranged in a staggered manner to prevent interference between the first rack 403 and the second rack 602.

[0036] In one embodiment, as Figure 1 、 Figure 2 and Figure 5 shown, the limiting plates 502 at the upper end of the window frame 100 and the limiting plates 502 at the lower end of the window frame 100 are distributed on both sides of the window door 200, and the front and back of the window door 200 can be limited according to the situation.

[0037] The above embodiments disclose a casement window that can be opened bidirectionally. Among them, when it is necessary to open the window door 200 outward, the locking nut 503 in the middle and lower part of the window frame 100 can be rotated to move it away from the limit plate 502 and the sliding groove 501, so that the limit plate 502 can slide inside the sliding groove 501. After moving to a suitable position, the locking nut 503 is rotated again to make it close to the limit plate 502 and the sliding groove 501, and the limit plate 502 is limited and fixed by increasing the friction force. Subsequently, by pulling the handle 703, the sliding rod 702 is driven to approach the handle 701, so that the sliding rod 702 disengages from the limit hole. Then, the handle 701 is rotated to drive the rotating column 401, thereby driving the second rotating gear 601 to rotate, and then driving the second rack 602 and the pin block 603 to move away from the inside of the window door 200, thus releasing the limit on the window door 200 and enabling it to be opened outward. When the rotating column 401 drives the second rack 602 away from the window door 200, the first rotating gear 402 will be driven to rotate, thereby driving the first rack 403 and the bent strip 404 to rise, and then driving the retractable rolling curtain 300 to rise until it reaches the storage groove for storage, preventing the wind from blowing the retractable rolling curtain 300. When it is not necessary to open the window door 200, the window door 200 can be pulled into the window frame 100. Subsequently, the handle 703 is pulled again to drive the handle 701 and the rotating column 401 to rotate, so that the second rack 602 drives the pin block 603 to approach the inside of the window door 200, thereby limiting and fixing it. After canceling the pulling force on the handle 703, under the action of the spring, the sliding rod 702 will enter the limit hole again to limit the handle 701. When the second rack 602 approaches the inside of the window door 200, the first rack 403 and the retractable rolling curtain 300 will descend, moving away from the storage groove, so that the retractable rolling curtain 300 can be pulled according to needs for shading. When it is necessary to open the window door 200 inward, the locking nut 503 in the middle and lower part of the window frame 100 can be rotated again to make the limit plate 502 reach the bottom of the sliding groove 501. At this time, the locking nut 503 in the upper middle part of the window frame 100 can be rotated to lower the limit plate 502 in the upper middle part of the window frame 100, thereby limiting the window door 200 so that it can only be opened inward into the room.

[0038] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
