[0002] As one type of building doors and windows, outward-opening doors and windows are usually used for indoor and outdoor entrances or partitions. The name of this type of doors and windows comes from their operation mode, that is, the door is opened and closed by pushing and pulling toward the outside.

[0042] In order to solve the above-mentioned technical problems existing in the prior art, in the outward-opening door and window system of the present application, the fixed frame is provided with a first frame, the wing edge profile is assembled on the first inner wall of the first frame, and is adjacent to the first outer wall of the first frame and is provided with a first seal; the movable frame is provided with a second frame, the second frame is provided with an extension portion, and the extension portion is provided with a second seal; when the movable frame is deflected to the first target position relative to the fixed frame, the movable frame and the fixed frame are located in the same plane, the second frame and the first frame are parallel to the glass, the first seal is clamped between the wing edge profile and the second frame, and the second seal is clamped between the extension portion and the second outer wall of the first frame; when deflected to the second target position, the second frame is separated from the first seal, and drives the extension portion and the second seal to separate from the second outer wall of the first frame. When the movable frame is deflected to the first target position relative to the fixed frame, the door and window system is in a closed state, and the wing edge profile is arranged between the first inner wall of the first frame and the second frame. In view of the small distance between the first inner wall of the first frame and the second frame, it is equivalent to limiting the wing edge profile to a narrower width, so that a narrower side wing can be set for the fixed frame, thereby reducing the frame width at the junction of the fixed frame and the movable frame.

[0043] The specific expression of parameters such as shape, quantity, size, etc. of any one of the fixed frame, movable frame, first frame, wing edge profile, first seal, second frame, extension portion, and second seal clamp can be determined according to the adaptability required by the actual scenario, and this application does not limit it.

[0044] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly described below in conjunction with specific embodiments and corresponding drawings. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. In the absence of conflict, the following embodiments and their technical features can be combined with each other and also belong to the technical solutions of the present application.

[0045] In the description of the embodiments of the present application, terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", and "counterclockwise" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the corresponding embodiments, rather than indicating or implying that a device or element must have a specific orientation, be constructed and operated in a specific orientation, and should not be understood as a limitation on the present application.

[0046] For the convenience of describing and understanding the scheme of the present application, the gravity direction g is referred to as the second direction y below. When the outward-opening door and window system is installed on a building, the height direction of the door and window system is the second direction y. Correspondingly, the width direction of the door and window system is referred to as the first direction x, and the thickness direction is referred to as the third direction z. The first direction x, the second direction y and the third direction z are perpendicular to each other and can be regarded as the three coordinate axes of the three-dimensional rectangular coordinate system. It should be understood that the so-called verticality in the whole application does not require that the angle between the two must be 90°, but allows a deviation of ±10°, that is, the so-called verticality can be understood as the angle between any two directions is 80° to 100°. Similarly, the so-called parallelism in the whole application does not require that the angle between the two must be 0° or 180°, but allows a deviation of ±10°, that is, the so-called parallelism can be understood as the angle between any two directions is 0° to 10° or 170° to 190°.

[0047] Please also read Figures 1 to 5 As shown, an outward-opening door and window system (may be referred to as "door and window system" or "outward-opening door and window") of an example of the present application includes a fixed frame 1, at least one movable frame 2 and glass 3. Specifically, the fixed frame 1 can be installed on a target wall, that is, the fixed frame 1 can be installed and fixed on the wall of a building as a fixed frame of the outward-opening door and window system, thereby supporting and guiding the movable frame 2 to push and pull to open / close, wherein there is at least one movable frame 2, and is connected to at least one frame of the fixed frame 1, and the connection method includes but is not limited to screwing, etc., and the specific details can be referred to in the prior art, and the fixed frame 1 is deflected relative to the fixed frame 1 on the plane where the fixed frame 1 is located to open / close, because the deflection is achieved by pushing and pulling the movable frame 2, so the deflection opening / closing is also called push-pull opening / closing, and the glass 3 can be a tempered glass 3, and specifically a double-layer glass design can be adopted, and the glass 3 is connected in each movable frame 2, and the part of the fixed frame 1 other than the movable frame 2 can also be provided with glass 3, for example Figure 1 The outward-opening door and window shown can be provided with four glass sheets 3 of different sizes, one of which is located in the movable frame 2, so as to ensure the flexibility and expansibility of the outward-opening door and window system and realize a larger window opening area, that is, a larger see-through area.

[0048] During the specific implementation process, the fixed frame 1 can be fixed to the wall by expansion bolts, screws, adhesives and the like to ensure that the outward-opening door and window system can be stably and firmly connected to the building, and the connection portion between the fixed frame 1 and the wall can be waterproofed and sealed. Specifically, sealing strips, silicone and other materials are used to fill the gap between the fixed frame 1 and the wall to enhance air tightness and water tightness.

[0049] The fixed frame 1 may be composed of a plurality of frames 10, for example Figure 1In the example shown, the fixed frame 1 includes an installation frame 1a formed by four side frames 10 connected end to end in sequence. The installation frame 1a is used to be fixed to the wall by expansion bolts, screws, adhesives, etc. The fixed frame 1 also includes a cross-shaped middle muntin 1b, and the two ends of any middle muntin 1b of the cross-shaped middle muntin 1b are respectively connected to the two parallel side frames 10 corresponding to the installation frame 1a. The outward-opening door and window of this example is provided with a movable frame 2 and a door formed of glass. The two vertical side frames 20 of the movable frame 2 are respectively arranged adjacent to the vertical and horizontal middle muntin 1b, and the other two vertical side frames 20 are respectively arranged adjacent to the two vertical side frames 10 corresponding to the installation frame 1a. Here, in the example, there are a total of four side frames at the junction of the fixed frame 1 and the movable frame 2, which are respectively Figure 1 The joints shown are A, B, C, and D.

[0050] For ease of description, this document refers to the frame 10 of the fixed frame 1 in each joint as the first frame 10, and the frame 20 of the movable frame 2 as the second frame 20. The first frame 10 of the fixed frame 1 and the second frame 20 of the movable frame 2 are arranged adjacent to each other. The frame of each joint includes the first frame 10 and the adjacent second frame 20. The frame width of each joint can be understood as the sum of the widths of the first frame 10 and the adjacent second frame 20 when the outward-opening door or window is in a closed state.

[0051] The following description will first be made by taking the junction B as an example. Figure 2 is a schematic diagram of the border cross section of the joint B, which is described in terms of Figure 2 The side walls of each structural element are named according to the placement orientation shown.

[0052] Combination Figure 1 and Figure 2 As shown, the first frame 10 is a horizontal middle wall 1b, and the cross section of the first frame 10 is rectangular, and thus includes four side walls. A wing edge profile 110 is assembled on the first inner wall of the first frame 10, and the first inner wall is the side wall facing the movable frame 2. Figure 1 In the scene shown, the first inner wall can be regarded as the upper wall of the first frame 10; the first outer wall 101 and the second outer wall 102 of the first frame 10 are arranged opposite to each other and are both vertically connected to the first inner wall, the first outer wall 101 is arranged toward the interior, and the second outer wall 102 is arranged toward the exterior, and the wing profile 110 is adjacent to the first outer wall 101 and is provided with a first sealing member 111.

[0053] An extension portion 200 is disposed on the second frame 20 , and a second sealing member 201 is disposed on the extension portion 200 .

[0054] The movable frame 2 can be deflected and opened / closed relative to the fixed frame 1, wherein:

[0055] When deflected to the first target position, that is, when the outward-opening door and window in this example is in a closed state, the movable frame 2 and the fixed frame 1 are located in the same plane, the second frame 20 and the first frame 10 are parallel to the glass 3, the first seal 111 is clamped between the wing profile 110 and the second frame 20, and the second seal 201 is clamped between the extension portion 200 and the second outer wall 102 of the first frame 10. At this time, the first seal 111 and the second seal 201 can seal the opposite sides of the first frame 10 and the second frame 20, that is, seal both sides of the frame at the joint B, so that the outdoors and the indoors are sealed and isolated.

[0056] When deflected to any second target position other than the first target position, for example, when the movable frame 2 and the glass 3 are pushed toward the outside, the outward-opening door and window of this example can be in an open state at any angle, the second frame 20 is separated from the first seal 111, and the extension 200 and the second seal 201 are driven to separate from the second outer wall 102 of the first frame 10, and at this time, the two sides of the frame at the junction B are connected, so that the outside and the room are connected. In the process of switching from the second target position to the first target position, the movable frame 2 and the glass 3 are pulled toward the room, and the second frame 20 moves toward the first seal 111 until it contacts the first seal 111. In this process, the second frame 20 drives the extension 200 and the second seal 201 to move toward the second outer wall 102 of the first frame 10 until it contacts the second outer wall 102 of the first frame 10, so that the first seal 111 is sandwiched between the wing edge profile 110 and the second frame 20, and the second seal 201 is sandwiched between the extension 200 and the second outer wall 102 of the first frame 10.

[0057] When the movable frame 2 is deflected to the first target position relative to the fixed frame 1, the outward-opening door and window is in a closed state, and the wing edge profile 110 is arranged between the first inner wall of the first frame 10 and the second frame 20. In view of the small distance between the first inner wall of the first frame 10 and the second frame 20, it is equivalent to limiting the wing edge profile 110 to a narrower width. At the same time, in order not to affect the deflection of the second frame 20 relative to the first frame 10 at any angle to realize the opening of the outward-opening door and window at any angle, it is also necessary to limit the wing edge profile 110 to a narrower width. Here, the example of the present application can set narrower side wings for the fixed frame 1, which makes the width of the frame 10 of the fixed frame 1 smaller as a whole, and can also reduce the frame width at the junction of the fixed frame 1 and the movable frame 2 without affecting the sealing performance.

[0058] exist Figure 2In the example shown, the fixed frame 1 includes a first inner profile 121, a first outer profile 122 and a first connecting member 123, wherein the first connecting member 123 is disposed between the first inner profile 121 and the first outer profile 122, and the first inner wall of the first frame 10 can be composed of the first inner profile 121, a first connecting member 123 and a side wall of the first outer profile 122 located on the same side, and the three side walls located on the same side are located on the same wall surface as a whole, and the latch teeth disposed on the side of the first inner profile 121 and the first outer profile 122 are externally extending elements or protruding elements disposed on the side wall, and can be integrally formed with the corresponding profile side wall. The inner sides of the first inner profile 121 and the first outer profile 122 are disposed facing each other, and the exposed side of the first inner profile 121 serves as the first outer wall 101 of the first frame 10, and the exposed side of the first outer profile 122 serves as the second outer wall 102 of the first frame 10. The first inner profile 121 is provided with a first latching tooth 124, and the first side of the wing profile 110 is engaged with the first latching tooth 124. The first sealing member 111 is provided at the second side of the wing profile 110. The first side and the second side of the wing profile 110 are respectively two side portions of the wing profile 110 along the width direction. The second outer wall 102 is provided with a second latching tooth 125.

[0059] The movable frame 2 includes a second inner profile 211, a second outer profile 212 and a second connecting member 213, wherein the second connecting member 213 is disposed between the second inner profile 211 and the second outer profile 212. The inner sides of the second inner profile 211 and the second outer profile 212 are disposed facing each other, the exposed side of the second inner profile 211 serves as the third outer wall 202 of the second frame 20, and the exposed side of the second outer profile 212 serves as the fourth outer wall 203 of the second frame 20. A protrusion 214 is disposed on the side of the second inner profile 211 facing the first frame 10, and the protrusion 214 is disposed opposite to the third outer wall 202 of the movable frame 2. The so-called opposite arrangement can be understood as having a minimum distance between the planes where the two are located that is not equal to zero, for example, the side of the protrusion 214 facing the third outer wall 202 can be parallel to the third outer wall 202, thereby forming a notch 215. The extension portion 200 extends along the exposed side of the second outer profile 212 to form the fourth outer wall 203 of the second frame 20.

[0060] For Figure 2 In the example shown, when the movable frame 2 deflects relative to the fixed frame 1 , the first seal 111 contacts or separates from the side of the protrusion 214 facing the third outer wall 202 , and the extension 200 drives the second seal 201 to contact or separate from the second latching tooth 125 .

[0061] Optionally, when deflected to the first target position, the width of the wing edge profile 110 is less than the minimum distance between the second frame 20 and the first frame 10. The so-called width refers to the relative direction of the second frame 20 and the first frame 10. Figure 2 The second direction y is shown.

[0062] Please continue reading Figure 2 As shown, when deflected to the first target position, that is, when the outward-opening door and window is in a closed state, the exposed side of the wing edge profile 110, the first outer wall 101 of the first frame 10, and the third outer wall 202 of the second frame 20 can be located on the same wall surface. Here, on the side of the outward-opening door and window facing the indoor room, the frame seam at the joint B (that is, the joint of the first frame 10 and the second frame 20) is relatively smooth, and the coplanarity of the entire outward-opening door and window facing the indoor room is relatively high.

[0063] Optionally, when deflected to the first target position, the cavity formed by the exposed side of the wing edge profile 110, the extension portion 200, the first inner wall of the first frame 10 and the second inner wall of the second frame 20 is a rectangular cavity, where the so-called rectangular cavity means that the cross-sectional shape of the cavity is rectangular, and the second inner wall of the second frame 20 faces the first inner wall of the first frame 10. Figure 1 In the scene shown, the second inner wall can be regarded as the lower wall of the second frame 20. The second inner wall can be composed of a protrusion 214, a second connecting member 213 and a side wall on the same side of the second outer profile 212, and the three side walls on the same side are located on the same wall surface as a whole, and the latching teeth provided on the side of the second outer profile 212 are externally extending elements or protruding elements provided on the side wall, and can be integrally formed with the side wall of the second outer profile 212.

[0064] In one example, the widths of the first connector 123 and the second connector 213 can be equal, so that the distance between the first inner profile 121 and the first outer profile 122 is equal to the distance between the second inner profile 211 and the second outer profile 212. A first isolation cavity 112 is provided between the first side portion and the second side portion of the wing edge profile 110, and the first inner profile 121 and the second inner profile 211 are both provided with a second isolation cavity 113. The thickness of the wing edge profile 110 can be equal to the thickness of the first inner profile 121 and the second inner profile 211, and the widths of the first isolation cavity 112 and the second isolation cavity 113 can be equal, so that the wing edge profile 110 has a larger cavity and good structural strength. The so-called widths of the first isolation cavity 112 and the second isolation cavity 113 refer to the relative directions along the first outer wall 101 and the second outer wall 102.

[0065] Optionally, a heat insulation material is provided in the first isolation cavity 112, which is not shown in the figure. Based on this design, the heat insulation function of the outward-opening door and window can be enhanced, that is, the performance of the outward-opening door and window system can be improved as a whole. The heat insulation material may include polystyrene foam and polyurethane foam. Polystyrene foam acts as a heat insulation barrier to reduce heat conduction, while polyurethane foam further improves the sealing and heat insulation effects through its efficient filling and sealing performance. This double insulation design can improve the performance of the door and window system.

[0066] Specifically, refer to Figure 5 Based on the first isolation cavity 112, the polystyrene foam can be attached to the inner wall of the first isolation cavity 112, and attached around the inner wall, so that the polystyrene foam encloses a material isolation cavity, and then the polyurethane foam is poured into the material isolation cavity, thereby performing a double insulation design.

[0067] It should be noted that polystyrene foam has good thermal insulation properties, and it can be used as the side wall material of the first isolation cavity 112 to play a thermal insulation role. In addition, polyurethane foam can be poured into the material isolation cavity to further fill the gaps and form a dense structure, thereby improving the air tightness of doors and windows, preventing air leakage and heat loss, enhancing the overall thermal insulation effect, and preventing heat conduction caused by air convection. On the other hand, the preset thickness of the polystyrene foam can be 1 / 5-1 / 3 of the cavity height of the first isolation cavity 112, and the elasticity of the polystyrene foam itself can also be used to buffer the expansion of the polyurethane foam and the hard contact with the first isolation cavity 112 after curing.

[0068] The combination of polystyrene foam and polyurethane foam can bring out the advantages of both materials and optimize the thermal insulation performance of the outward-opening door and window system. At the same time, polystyrene foam can effectively isolate polyurethane foam from the corresponding profiles, facilitating subsequent specific disassembly and assembly needs and facilitating the reuse of profiles.

[0069] In order to allow the polyurethane foam to expand evenly in the material isolation cavity, reinforcing ribs are further provided in the material isolation cavity. The reinforcing ribs extend to the opposite ends of the first isolation cavity 112, and the reinforcing ribs are designed in a bow-shaped structure. The reinforcing ribs can be mixed with the polyurethane foam in the material isolation cavity. Specifically, the bow-shaped reinforcing ribs help to evenly disperse the externally applied pressure throughout the isolation cavity to avoid stress concentration in local areas. Mainly, the polyurethane foam will expand during the infusion process, which may cause uneven foaming. The reinforcing ribs serve as physical barriers to guide the polyurethane foam to diffuse evenly in the material isolation cavity to prevent the formation of voids or air pockets. The uneven foaming area and the reinforcing ribs provide a fixed frame support for the polyurethane foam during the foaming process, preventing the foaming material from flowing too fast or becoming irregularly shaped during expansion, thereby ensuring the integrity of the foaming filling; on the other hand, a certain expansion force will be generated after the polyurethane foam is solidified. The present application uses polystyrene foam as an elastic buffer and divides the solidified area of ​​the polyurethane foam through reinforcing ribs to reduce its expansion force. That is, the bow-shaped reinforcing ribs ensure that the polyurethane foam is evenly filled in the cavity, avoiding the reduction of thermal insulation performance due to the concentration or uneven distribution of the polyurethane foam, and at the same time slowing down the expansion force of the polyurethane foam, thereby improving the comprehensive performance of the outward-opening door and window system.

[0070] like Figure 2 As shown, the protrusion 214 may also be provided with an isolation cavity, referred to as a third isolation cavity 216 , and the third isolation cavity 216 may also be provided with any of the aforementioned examples of heat insulation materials.

[0071] for Figure 1 At any of the joints A, C, and D shown in the figure, the first frame 10 and the second frame 20 may also adopt the aforementioned structural design, such as Figures 3 to 5 As shown, the structures of each joint are not described in detail here. For joint A, the first frame 10 is the vertical middle frame 1b, and the second frame 20 is the left frame of the movable frame 2. For joint C, the first frame 10 is the right frame of the installation frame 1a, and the second frame 20 is the right frame of the movable frame 2. For joint D, the first frame 10 is the upper frame of the installation frame 1a, and the second frame 20 is the upper frame of the movable frame 2.

[0072] It should be noted that any of the above-mentioned first borders 10 is a whole profile, and along the extension direction of the profile, the cross-sectional shape of the profile at any position of the junction with the second border 20 can be exactly the same, and the structure at each position will not be described in detail here.

[0073] In other examples where the fixed frame 1 is not provided with the middle stile 1b, the outward-opening door and window only includes the installation frame 1a, and the first frame 10 is the frame corresponding to the installation frame 1a.
