Description

Technical Field

[0001] The utility model relates to a door and window, in particular to a window frame and a narrow-frame casement window. Background Art

[0002] In a casement window, the window sash rotates within the window frame to open or close the window. For outward-opening casement windows, since an outer retaining edge is provided on the outdoor side of the window frame, it is usually necessary to add a conversion frame at the bottom of the window frame to raise the position where the bottom of the window frame is connected to the window sash, so that hinges, locks and other hardware can be installed on the top side of the conversion frame to achieve the connection with the window sash. However, this increases the frame height of the window frame, resulting in a relatively large proportion of the window frame in current casement windows, affecting the overall appearance. Therefore, a window frame with a narrower frame height is urgently needed. Utility Model Content

[0003] The purpose of the utility model is to provide a window frame and a narrow-frame casement window to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A window frame includes: a lower frame having a first mounting groove on its top side; a conversion frame connected to the top side of the lower frame, the conversion frame being closer to the indoor side of the lower frame relative to the first mounting groove, and the conversion frame being provided with an upwardly extending baffle.

[0006] This technical solution has at least the following beneficial effects: the first mounting groove is used to install hardware such as external hinges to connect external window sashes, and the baffle used to block and divide the indoor space is set on the conversion frame, and the conversion frame is located near the lower frame and close to the indoor position. At this time, space for installing and accommodating external window sashes is provided at the outdoor position of the lower frame, thereby reducing the structure at the outdoor position, thereby effectively reducing the frame height of the window frame, reducing the area proportion of the window frame in the entire window, and helping to improve the overall appearance.

[0007] As a further improvement to the above technical solution, a second mounting slot is provided on the top side of the conversion frame, closer to the outdoor side of the conversion frame than the baffle. The second mounting slot is used to accommodate external hardware such as locks, which interact with the window sash. This separates the hinges and locks installed on the window sash from the lower frame, allowing for a more rational distribution of the overall structural layout and further reducing the frame height.

[0008] As a further improvement to the above technical solution, a first relief recess is provided at the top of the outdoor side of the lower frame. The first relief recess allows the external window sash to escape when it is closed. At this time, the side of the window moves into the first relief recess. The first relief recess improves the sealing effect of the side of the window sash, making it difficult for rainwater to flow back through the abutment between the window sash and the lower frame.

[0009] As a further improvement to the above technical solution, the lower frame is provided with a drainage hole on the outdoor side of the first mounting groove. When strong outdoor wind pressure causes rainwater to enter the window sash, the rainwater on the window sash can drip into the first mounting groove, collect, and drain outdoors through the drainage hole, and finally be discharged from the first relief concave corner.

[0010] As a further improvement to the above technical solution, a sealing groove is provided on the outdoor side of the baffle. During use, an external sealing strip can be inserted into the sealing groove. When the window sash is closed, the indoor side of the window sash presses against the sealing strip and then against the baffle, thereby further improving the sealing between the window sash and the baffle.

[0011] As a further improvement to the above technical solution, a third mounting slot is provided on the top side of the conversion frame, which is closer to the indoor side of the conversion frame than the baffle. The third mounting slot can also be used to connect external hardware such as locks. When in use, the screen fan can be installed on the lower frame near the indoor side. When the screen fan is closed, the screen fan abuts against the indoor side of the baffle, and the screen window is locked by cooperating with the lock or other hardware installed in the third mounting slot on the lower frame.

[0012] As a further improvement to the above technical solution, a limiting rib is provided on the top side of the lower frame, a second avoidance concave angle is provided on the top of the indoor side of the lower frame, the outdoor side of the conversion frame abuts against the limiting rib, and the indoor side of the conversion frame and the side of the second avoidance concave angle are flush with each other. When installing the conversion frame, the limiting rib can be used to quickly install and position the conversion frame on the lower frame, improving the efficiency and stability of the connection between the conversion frame and the lower frame. In addition, the conversion frame and the indoor side are flush with the side of the second avoidance concave angle, forming a mating surface that abuts against each other when the screen fan is closed, which can not only provide space for the screen fan to avoid when closed, but also make the overall structure more compact.

[0013] As a further improvement to the above technical solution, a buckle groove is provided on the top side of the lower frame. When the glass needs to be installed, the conversion frame can be removed from the lower frame, exposing the buckle groove on the top side of the lower frame. External buckles can be connected to the buckle groove to secure the glass.

[0014] A narrow-frame casement window comprises a movable sash and the above-mentioned window frame, wherein the window frame is surrounded by at least one opening, the movable sash is located in one of the openings, and a hinge is connected between the bottom side of the movable sash and the first mounting groove.

[0015] This technical solution has at least the following beneficial effects: the window frame is a rectangular frame with openings formed inside. Depending on the needs of use, the number of openings can be one or more. The movable sash is installed in one of the openings in the window frame. At this time, the movable sash is rotatably connected to the first mounting groove on the window frame through a hinge on its bottom side. Since the structure in the outdoor position is reduced inside the window frame, the frame height of the window frame is effectively reduced, and the area proportion of the window frame in the entire window is reduced, which is conducive to improving the overall appearance.

[0016] As a further improvement to the above technical solution, the present invention further includes a fixed sash, the fixed sash being positioned within the other of the openings, the bottom of the fixed sash being formed with a connecting rib that engages with the first mounting groove. When the window frame is also equipped with the fixed sash, the fixed sash is installed within the other opening, the convertible frame is removed from the lower frame, and the connecting rib at the bottom of the fixed sash engages with the first mounting groove, thereby securing the fixed sash.

[0026] Reference Figure 1 A window frame includes a lower frame 100 and a conversion frame 200, wherein a first mounting groove 110 is provided on the top side of the window frame; the conversion frame 200 is connected to the top side of the lower frame 100, and the conversion frame 200 is closer to the indoor side of the lower frame 100 relative to the first mounting groove 110, and an upwardly extending baffle 210 is provided on the conversion frame 200. In actual application, in order to improve the thermal insulation performance of the lower frame 100, an insulation strip can be installed in the lower frame 100. At this time, the first mounting groove 110 is located on the outdoor side relative to the insulation strip, and the conversion frame 200 is located on the indoor side relative to the insulation box.

[0027] As can be seen from the above, the first mounting groove 110 is used to install hardware such as external hinges to connect external window sashes, and the baffle 210 for blocking and dividing the indoor space is arranged on the conversion frame 200, and the conversion frame 200 is located near the lower frame 100 and close to the indoor position. At this time, the outdoor position of the lower frame 100 provides space for installing and accommodating external window sashes, thereby reducing the structure at the outdoor position, thereby effectively reducing the frame height of the window frame, reducing the area proportion of the window frame in the entire window, and helping to improve the overall appearance.

[0028] The lock on the window sash can be installed at a peripheral location where the window sash mounting hinge is located. To accommodate different mounting structures, in this embodiment, a second mounting slot 220 is provided on the top side of the conversion frame 200. The second mounting slot 220 is closer to the outdoor side of the conversion frame 200 than the baffle 210. The second mounting slot 220 is used to accommodate external hardware such as a lock, thereby interoperating with the window sash. Separating the mounting locations of the hinge and lock on the window sash from the lower frame 100 allows for a more rational distribution of the overall structural layout and helps further reduce the frame height.

[0029] To enhance the sealing effect of the external window sash when it is closed and abuts the lower frame 100, in this embodiment, a first relief recess 120 is provided at the top of the outdoor side of the lower frame 100. The first relief recess 120 allows the external window sash to avoid the external window sash when it is closed. At this time, the side of the window moves into the first relief recess 120. The first relief recess 120 can enhance the sealing effect of the side of the window sash, making it difficult for rainwater to flow back from the abutment between the window sash and the lower frame 100. In actual use, a rubber strip can be installed at the bottom of the window sash near the first relief recess 120, so that the rubber strip abuts the inside of the first relief recess 120, thereby further enhancing the sealing effect between the window sash and the lower frame 100.

[0030] In some embodiments, the lower frame 100 is provided with a drainage hole 111 on the outdoor side of the first mounting groove 110. When the outdoor wind pressure is high and rainwater enters the window sash, the rainwater on the window sash can drip into the first mounting groove 110, collect, and drain outdoors through the drainage hole 111, and finally drain out of the first avoidance concave corner 120.

[0031] When the window sash is closed, a seal is formed on the exterior side of the window sash at the first relief recess 120, and another seal is formed on the interior side of the window sash at the baffle 210. To enhance the sealing effect at this location, in this embodiment, a sealing groove 211 is provided on the exterior side of the baffle 210. During use, an external sealing strip can be inserted into the sealing groove 211. When the window sash is closed, the interior side of the window sash presses against the sealing strip and then against the baffle 210, further enhancing the sealing between the window sash and the baffle 210.

[0032] In some casement windows with mosquito-proofing functions, a screen fan is installed near the indoor location. To achieve mutual cooperation between the screen fan and the conversion frame 200, in this embodiment, a third mounting slot 230 is provided on the top side of the conversion frame 200. The third mounting slot 230 is closer to the indoor side of the conversion frame 200 than the baffle 210. The third mounting slot 230 can also be used to connect external hardware such as locks. When in use, the screen fan can be installed near the indoor side of the lower frame 100. When the screen fan is closed, the screen fan abuts against the indoor side of the baffle 210, and the lock or other hardware installed in the third mounting slot 230 on the lower frame 100 is locked.

[0033] When the screen fan is closed, it can directly rest against the indoor side of the lower frame 100. At this time, the bottom side of the screen fan will protrude from the lower frame 100, affecting the overall appearance. In order to make the overall structure more compact, in this embodiment, a limiting rib 130 is provided on the top side of the lower frame 100, and a second avoidance concave angle is provided on the top of the indoor side of the lower frame 100. The outdoor side of the conversion frame 200 rests against the limiting rib 130, and the indoor side of the conversion frame 200 and the side of the second avoidance concave angle are flush with each other. When installing the conversion frame 200, the limiting rib 130 can be used to quickly install and position the conversion frame 200 on the lower frame 100, thereby improving the connection efficiency and stability between the conversion frame 200 and the lower frame 100. In addition, the conversion frame 200 and the indoor side are flush with the side of the second avoidance concave angle, forming a mating surface that rests against the screen fan when it is closed, which can provide space for the screen fan to avoid when it is closed and make the overall structure more compact.

[0034] In actual application, the conversion frame 200 and the lower frame 100 are detachably connected. Screws can be driven into the conversion frame 200 and connected to the lower frame 100, thereby connecting and fixing the conversion frame 200 and the lower frame 100 to each other.

[0035] The lower frame 100 can be used to mount not only movable window sashes but also fixed window sashes. Therefore, in this embodiment, a buckle strip groove 140 is provided on the top side of the lower frame 100. When fixed glass needs to be installed, the conversion frame 200 can be removed from the lower frame 100, exposing the buckle strip groove 140 on the top side of the lower frame 100. External buckle strips can be connected to the buckle strip groove 140 to secure the glass.

[0036] A narrow frame casement window, such as Figure 2 As shown, it includes: a movable fan 300 and a window frame as mentioned above, wherein the window frame is surrounded by at least one hole, the movable fan 300 is located in one of the holes, and a hinge is connected between the bottom side of the movable fan 300 and the first installation groove 110.

[0037] In this narrow-frame casement window, the window frame is a rectangular frame with openings formed inside. Depending on the needs of use, the number of openings can be one or more. The movable fan 300 is installed in one of the openings of the window frame. At this time, the movable fan 300 is rotatably connected to the first mounting groove 110 on the window frame through the hinge on its bottom side. Since the structure in the outdoor position is reduced in the window frame, the frame height of the window frame is effectively reduced, and the area proportion of the window frame in the entire window is reduced, which is conducive to improving the overall appearance.

[0038] The present invention also includes a fixed fan 400, such as Figure 3 As shown, the fixed sash 400 is located in the other opening, and a connecting rib is formed on the bottom of the fixed sash 400, which is engaged and connected with the first mounting groove 110. When the window frame is also equipped with the fixed sash 400, the fixed sash 400 is installed in the other opening. At this time, the convertible frame 200 is removed from the lower frame 100, and the connecting rib at the bottom of the fixed sash 400 is engaged and connected with the first mounting groove 110 to secure the fixed sash 400. In actual application, the buckle portion of the fixed sash 400 can also be engaged and connected with the third mounting groove 230, thereby connecting and fixing the fixed sash 400 at both the outdoor and indoor positions.

[0039] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
