Description

Technical Field

[0001] The invention relates to the technical field of outward-opening doors and windows, in particular to an outward-opening door and window system with an extremely narrow frame. Background Art

[0002] Outward-opening doors and windows are an important form of door and window opening, and are named because they open toward the outside of the building. Outward-opening doors and windows are widely used because they do not occupy indoor space. With the overall improvement of social quality of life, outward-opening doors and windows have evolved from traditional outward-opening forms to multiple or combined forms that can be tilted in one or more directions to meet more individual specific functional needs such as indoor micro-ventilation.

[0003] Door and window profiles are the main structural frames of doors and windows. For outward-opening doors and windows, they usually include a frame connected to the wall, and the outer and inner frames of the door / window sashes (fans). Among them, the inner and outer frames of the sashes are usually used in pairs. The inner frame is used to install glass, handle hardware, sliding brace / hinge hardware, etc., and the outer frame is used to connect to the frame and install locking points / anchor points, sliding brace / hinge hardware, etc. Among them, the installation positions of locking points / anchor points, sliding braces / hinges, handles, etc. on the profile are generally called the hardware channels of the profile. In the smart door and window system, sensors, power, transmission components, smart system wiring, etc. are usually also chosen to be implemented in the hardware channel.

[0004] Therefore, the existing outward opening door and window system has the following technical problems:

[0005] (1) Usually, the location where the hardware is installed is also the installation channel for the handle and the lock point, and the installation channel for the transmission parts of the handle. When the channel is located on the outdoor side of the outward-opening door and window system, the handle that can only be installed on the indoor side needs to penetrate the entire profile for transmission (transmission from the inner frame of the outward-opening door and window sash profile structure to the outer frame of the outward-opening door and window sash profile structure, and then from the outer frame of the outward-opening door and window sash profile to the outer frame of the outward-opening door and window frame profile structure), that is, there is a long transmission stem. A long transmission stem will deteriorate the transmission accuracy and reliability (for example, there will be problems such as the handle part turning at an angle or the installation and docking of the lock structure being loose). To improve the transmission accuracy and reliability, it is necessary to design a complex transmission system through the cooperation of a large number of transmission structures. These transmission structures are usually arranged at the sash profile structure and the frame profile structure of the outward-opening door and window system. Therefore, the setting of the complex transmission system will make the frame at a wider level, and it is impossible to achieve the design of an extremely narrow frame.

[0006] (2) In the existing outward-opening door and window design, since the transmission structure runs through the outdoor side and the indoor side, the heat conduction path between the indoor and outdoor sides is increased. When faced with the product demand for indoor thermal insulation, the transmission structure of traditional outward-opening doors and windows is not conducive to the realization of thermal insulation and energy saving.

[0007] (3) In the existing outward-opening door and window design, due to the need to maintain a high transmission accuracy and reliability of the transmission structure, a complex transmission system needs to be adopted, which increases the thickness of the frame and thus increases the heat conduction efficiency of the frame to the indoor and outdoor sides.

[0008] (4) The existing outward-opening door and window designs have a relatively thick frame setting, thereby reducing the proportion of glass occupied by the window body, limiting the area of ​​the lighting surface, and affecting the overall design aesthetics of the outward-opening door and window. Summary of the invention

DETAILED DESCRIPTION

[0094] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0095] Reference Figure 1-Figure 12 .

[0096] Embodiment 1:

[0097] The present embodiment provides an extremely narrow frame outward opening door and window system, comprising: an outward opening door and window sash body profile structure having a first outer frame 11 and a first inner frame 12; an outward opening door and window frame profile structure 21 having a second outer frame 21 and a second inner frame 22; a window opening assembly 3 having a first locking structure 31 and a second locking structure 32; wherein the first locking structure 31 is configured on the first inner frame 12, and the second locking structure 32 is configured on the second inner frame 22; wherein the first locking structure 31 has a first state and a second state; Wherein, when the first locking structure 31 is in the first state, the first locking structure 31 cooperates with the second locking structure 32 to limit the relative positions of the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21, so that the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 are in a restricted opening and closing state; wherein, when the first locking structure 31 is in the second state, the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 are in a free opening and closing state.

[0098] In the profile door and window structure, the sash can be divided into open sash and fixed sash according to whether the sash can be opened. Usually, the same opening will have a combination structure of some open sashes and other fixed sashes. In order to make the profile structure present integrity, it is usually necessary to make the profile base frame of the open sash and the fixed sash share the same structure, which forms the frame structure of the door and window. The frame structure is first installed in the opening and fastened to the wall / building. The open sash structure also includes two parts, one part is the outward-opening door and window frame profile structure 21 connected to the frame, and the other part is the outward-opening door and window sash body profile structure connected to the outward-opening door and window frame profile structure 21 (usually) through hardware (such as sliding braces).

[0099] The extremely narrow frame outward-opening door and window system provided in this embodiment includes an outward-opening door and window sash body profile structure, an outward-opening door and window frame profile structure 21 and a window opening assembly 3. The first locking structure 31 of the window opening assembly 3 is configured on the first inner frame 12 of the outward-opening door and window sash body profile structure, and the second locking structure 32 of the window opening assembly 3 is configured on the second inner frame 22 of the outward-opening door and window frame profile structure 21. The state control between the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 is achieved by driving and controlling the different states of the first locking structure 31. Among them, when the first locking structure 31 is in the first state (i.e. the locked state), the first locking structure 31 cooperates with the second locking structure 32 to fix the relative position of the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21, so that it is in a restricted opening and closing state; when the first locking structure 31 is in the second state (i.e. the unlocked state), the first locking structure 31 withdraws and cooperates with the second locking structure 32 to release the restriction on the relative position of the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21, so that it is in a free opening and closing state.

[0100] It should be noted that the door and window sash body profile structure is described as having two technical features, the first inner frame 12 and the first outer frame 11, and the outward-opening door and window frame profile structure 21 is described as having two technical features, the second inner frame 22 and the second outer frame 21. However, it should be understood as the relativity between inside and outside, and the relative naming of inside and outside is set to clearly describe the unlocking components, and it is not to first position the door and window sash body profile structure and the outward-opening door and window frame profile structure 21 as "must consist of two parts, inside and outside", that is, the first inner frame 12 and the first outer frame 11, the second inner frame 22 and the second outer frame 21 can be a whole formed of the same material, and do not have to be two parts that can be separated in structure.

[0101] Therefore, this embodiment moves the window opening assembly 3 arranged on the outdoor side in the traditional outward-opening door and window system to the indoor side, that is, the first locking structure 31 originally arranged on the first outer frame 11 of the outward-opening door and window sash profile structure and the second locking structure 32 arranged on the second outer frame 21 of the outward-opening door and window frame profile structure 21 are moved from the outdoor side to the indoor side when opening and closing the window. Since the window opening handle is usually arranged on the indoor side, the transmission distance from the handle to the first locking structure 31 is shortened. With a shorter transmission distance, a high transmission accuracy can be maintained without using a complex transmission system, so that the system has a higher reliability. Compared with the traditional outward-opening door and window system, in order to maintain the transmission accuracy and reliability of the system, a complex transmission system composed of a large number of transmission structures needs to be adopted, resulting in the outward-opening door and window system needing to be configured with corresponding accommodation space to load these transmission structures, thereby making the outward-opening door and window system have a wider frame. When facing the product design requirements of an extremely narrow frame, it is impossible to take into account both product reliability and extremely narrow frame design. This embodiment shortens the transmission distance from the handle to the lock structure, and can maintain a high level of transmission accuracy without using a complex transmission system. As a result, it can achieve both extremely narrow frame product design and high product reliability. In addition, the simplification of the transmission structure reduces the frame thickness of the outward-opening doors and windows, increases the lighting surface, and can make the product more beautiful. On the other hand, the simplification of the transmission structure reduces the frame area of ​​the outward-opening doors and windows, increases the proportion of glass area, and significantly improves the thermal insulation effect.

[0102] At the same time, when facing the product demand for indoor thermal insulation, shortening the transmission structure to the first inner frame and the second inner frame can avoid the heat conduction caused by the transmission structure running through the indoor and outdoor sides in the traditional outward-opening door and window system, and achieve better thermal insulation and energy-saving effects.

[0103] Embodiment 2:

[0104] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the second inner frame 22 comprises: a second inner frame 22 profile body having a second inner frame mounting surface 221 and a second inner frame functional surface 222; wherein the second inner frame mounting surface 221 is the first surface of the inner frame of the second inner frame 22 profile body, which is used for connection with a building body and / or connection with a preassembled body connected to a building body; wherein the second inner frame functional surface 222 is the second surface of the inner frame of the second inner frame 22 profile body, the second inner frame mounting surface 221 is arranged opposite to the second inner frame functional surface 222, and the second locking member 322 is arranged on the second inner frame mounting surface 221.

[0105] In this embodiment, the second inner frame 22 can be described as follows: the second inner frame installation surface 221 refers to the downward surface of the second inner frame 22, which can be divided into connection with the basic profile frame or connection with the building according to different installation forms; the second inner frame functional surface 222 refers to the upward surface of the second inner frame 22, on which the second locking member 322 and other hardware can be installed, including but not limited to handles, handle transmission parts, locking pins, locking points, sliding supports, anti-fall components, etc. Therefore, by cooperating with the first locking member 313, the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 can be driven and controlled to be in a free opening and closing state or a restricted opening and closing state.

[0106] Therefore, by arranging the first locking member 313 and the second locking member 322 for driving and controlling the outward-opening door and window sash profile structure and the outward-opening door and window frame profile structure 21 to be in a free opening and closing state or a restricted opening and closing state, as well as the hardware for realizing other outward-opening door and window functions on the indoor side, on the one hand, the transmission distance from the handle to the lock structure can be shortened, thereby improving the transmission accuracy and reliability of the system; on the other hand, it also avoids the situation in which the electrochemical corrosion caused by rain or humid environment that reduces the product life when the lock structure and hardware are arranged on the outdoor side.

[0107] Embodiment 3:

[0108] One of the optional implementation schemes of the extremely narrow frame outward-opening door and window system, the first inner frame 12, comprises: a first inner frame 12 profile body having a first inner frame installation surface 121, a first inner frame functional surface 122 and a first inner frame execution surface 123; wherein the first inner frame installation surface 121 is the first surface of the inner frame of the first inner frame 12 profile body, and is used to connect with the first outer frame 11; wherein the first inner frame functional surface 122 is the second surface of the inner frame of the first inner frame 12 profile body, the first inner frame functional surface 122 is arranged opposite to the second inner frame functional surface 222, the first locking piece 313 is arranged on the first inner frame functional surface 122, and a hardware channel is formed between the first inner frame functional surface 122 and the second inner frame functional surface 222; wherein the first inner frame execution surface 123 is the third surface of the inner frame of the first inner frame 12 profile body.

[0109] In this embodiment, the first inner frame 12 can be described as follows: the first inner frame installation surface 121 refers to the surface of the first inner frame 12 facing the outside of the room, which is used to connect with the first outer frame 11 to form the overall structure of the outward-opening door and window sash profile structure; the first inner frame functional surface 122 refers to the downward surface of the first inner frame 12, on which the first locking member 313 can be installed, and the first locking member 313 is used to cooperate with the second locking member 322 to drive and control the outward-opening door and window sash profile structure and the outward-opening door and window frame profile structure 21 to be in a free opening and closing state or a restricted opening and closing state. At the same time, a hardware channel is formed between the first inner frame functional surface 122 and the second inner frame functional surface 222, which is used to install and set hardware that performs various functions of the outward-opening door and window system; the first inner frame execution surface 123 refers to the surface of the first inner frame 12 facing upward or indoors, which is used to install and set rotating parts 311 such as handles.

[0110] Therefore, by forming a hardware channel between the first inner frame functional surface 122 and the second inner frame functional surface 222, a matching position is reserved for the first locking structure 31 and the second locking structure 32, and hardware for performing various functions of the outward-opening door and window system is installed. Compared with the traditional hardware channel configured on the outdoor side, the hardware channel configured on the indoor side can, on the one hand, shorten the transmission distance from the handle to the lock structure, thereby improving the transmission accuracy and reliability of the system; on the other hand, it also avoids the situation in which the electrochemical corrosion caused by rain or humid environment when the lock structure and hardware are arranged on the outdoor side reduces the product life.

[0112] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the first locking structure 31 comprises: a rotating member 311; a transmission assembly 312; and a first locking member 313; wherein the rotating member 311 is arranged on the first inner frame execution surface 123, and is used to obtain the rotational force when the first locking structure 31 performs the first state switching action; wherein the transmission assembly 312 is arranged on the first inner frame functional surface 122, and is used to transmit the rotational force to the first locking member 313; wherein the first locking member 313 is arranged in the hardware channel between the first inner frame 12 and the second inner frame 22, and is used to cooperate with the second locking structure 32 to drive the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 to perform the second state switching action when the first locking structure 31 performs the first state switching action.

[0113] In this embodiment, by configuring the first locking structure 31 including a rotating member 311, a transmission assembly 312 and a first locking member 313, the rotating member 311 is used to obtain the rotational force when the user performs the first state switching action. The rotating member 311 can be configured to include a handle and a rotating structure connected to the handle. In the smart door and window system, it can also be configured to include a micro motor and a rotating structure connected to the micro motor. When the user applies a rotational force to the handle or the micro motor applies a rotational force to perform the first state switching action, the rotating member 311 obtains the rotational force and transmits it to the transmission assembly 312, and then transmits it to the first locking member 313 through the transmission assembly 312; the transmission assembly 312 can be configured to include A number of mutually connected transmission parts are used to transmit the rotational force to the first locking part 313. Since the present embodiment moves the matching position of the first locking structure 31 and the second locking structure 32 inward to the hardware channel formed between the first inner frame 12 and the second inner frame 22, the number of transmission parts used can be greatly reduced, thereby improving the transmission accuracy of the transmission component 312; the first locking part 313 can generally be configured as a locking tongue or a protruding structure similar to a locking tongue. When receiving the rotational force transmitted by the transmission component 312, the locking tongue is driven to cooperate with the second locking structure 32, and drive and control the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 to be in a free opening and closing state or a restricted opening and closing state.

[0114] Embodiment 5:

[0115] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the first inner frame execution surface 123 is configured as an opposite surface of the first inner frame installation surface 121 and / or an opposite surface of the first inner frame functional surface 122 .

[0116] In this embodiment, the first inner frame execution surface 123 is used to install and set a rotating part 311 such as a handle. In different product requirements, the handle installation position can be set on the opposite side of the first inner frame installation surface 121, or on the opposite side of the first inner frame functional surface 122. In actual applications, a specific position can be selected according to customer needs.

[0117] Embodiment 6:

[0118] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the second locking structure 32 comprises: a fixing member 321; a second locking member 322; wherein the fixing member 321 is arranged on the second inner frame functional surface 222, and is used to connect the second inner frame 22 and the second locking member 322; wherein the second locking member 322 is arranged on the fixing member 321, and is used to cooperate with the first locking member 313 to drive the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 to perform a second state switching action when the first locking structure 31 performs a first state switching action.

[0119] In this embodiment, by configuring a second locking structure 32 including a fixing member 321 and a second locking member 322, the second locking member 322 is fixed to the second inner frame functional surface 222 using the fixing member 321. When the first locking structure 31 is in the first state, the second locking member 322 can cooperate with the first locking member 313 configured on the first inner frame functional surface 122 opposite to the second inner frame functional surface 222, so as to drive and control the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 to be in a restricted opening and closing state; when the first locking structure 31 is in the second state, the second locking member 322 withdraws from the cooperation with the first locking member 313 configured on the first inner frame functional surface 122 opposite to the second inner frame functional surface 222, so as to drive and control the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 to be in a free opening and closing state. The second locking member 322 can generally be configured as a lock core or a groove structure similar to a lock core, and the lock tongue configured by the first locking member 313 cooperates with the lock core to drive and control the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 to be in a free opening and closing state or a restricted opening and closing state. It should be noted that the fixing member 321 and the second locking member 322 are two components that are divided only by function, and both can also be configured as an integrated component provided with a fixing portion and a locking portion, and should not be interpreted as only having to include two components.

[0120] Embodiment 7:

[0121] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, when the first state switching action is switching from the first state to the second state, the second state switching action is switching from the free opening and closing state to the restricted opening and closing state; when the first state switching action is switching from the second state to the first state, the second state switching action is switching from the restricted opening and closing state to the free opening and closing state.

[0122] In this embodiment, the first locking structure 31 switches from the first state to the second state, which means that the first locking structure 31 and the second locking structure 32 change from a non-matching state to a matching state. Furthermore, the lock tongue of the first locking structure 31 extends into the lock core of the second locking structure 32. At this time, due to the limit fixation of the lock tongue and the lock core, the relative position of the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 is fixed, and its state is switched from a free opening and closing state to a restricted opening and closing state. The first locking structure 31 switches from the second state to the first state, which means that the first locking structure 31 and the second locking structure 32 change from a matching state to a non-matching state. Furthermore, the lock tongue of the first locking structure 31 withdraws from the lock core of the second locking structure 32. At this time, due to the release of the limit fixation of the lock tongue and the lock core, the relative position of the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 is released, and its state is switched from a restricted opening and closing state to a free opening and closing state.

[0123] Embodiment 8:

[0124] One of the optional implementation schemes of the extremely narrow frame outward-opening door and window system also includes: an outward-opening door and window sealing strip 4 having a strip supporting body 41 with a first connecting surface and a second connecting surface; wherein the first connecting surface is provided with a connecting portion 42, and the connecting portion 42 is used to connect to the outward-opening door and window sash profile structure; wherein the second connecting surface is provided with a sealing portion 43, and the sealing portion 43 includes a first sealing component 431 and a second sealing component 432; wherein the first sealing component 431 is used to form a first sealing structure with a first sealing fitting configured with the outward-opening door and window frame profile structure 21 when performing a window closing action; wherein the second sealing component 432 is used to form a second sealing structure with a second sealing fitting configured with the outward-opening door and window frame profile structure 21 when performing a window closing action.

[0125] The present embodiment is provided with a sealing strip arranged between the outward-opening door and window frame profile structure 21 and the outward-opening door and window sash profile structure, and is connected to the outward-opening door and window sash profile structure through the outward-opening door and window sealing strip 4, so that when the window is opened and closed, the outward-opening door and window sealing strip 4 moves with the outward-opening door and window sash profile structure, and when the window is closed, the outward-opening door and window sealing strip 4 forms a first sealing structure and a second sealing structure with the outward-opening door and window frame profile structure 21, thereby realizing the integrated formation of the first sealing structure and the second sealing structure, facilitating the installation and replacement of the sealing strip, and also improving the overall sealing performance.

[0126] It should be noted that the connecting portion 42 of the first connecting surface of the rubber strip support body 41 is connected to the outward-opening door and window sash body profile structure, and the sealing portion 43 of the second connecting surface of the rubber strip support body 41 forms a first sealing structure and a second sealing structure with the outward-opening door and window frame profile structure 21. The sealing portion 43 includes a first sealing member 431 and a second sealing member 432. The first sealing member 431 and the first sealing member configured with the outward-opening door and window frame profile structure 21 form a first sealing structure close to the outside, and the second sealing member 432 and the second sealing member configured with the outward-opening door and window frame profile structure 21 form a second sealing structure close to the inside. The first sealing structure close to the outside and the second sealing structure close to the inside formed by integration provide two layers of sealing for the outward-opening door and window system, thereby improving the sealing capability.

[0127] Therefore, this embodiment provides two layers of sealing structures, and provides a hardware channel for installing hardware such as the first locking structure 31 and the second locking structure 32 on the indoor side behind the two layers of sealing structures. This can change the current situation in which the hardware channels in traditional outward-opening door and window systems are easily subject to electrochemical corrosion due to rain or humid environments, provide sufficient watertight protection for the hardware, and improve product life.

[0128] Embodiment 9:

[0129] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the first sealing structure is a sealing structure close to the outside, and the second sealing structure is a sealing structure close to the inside; wherein, the distance from the sealing position of the second sealing structure to the rubber strip support body 41 is smaller than the distance from the sealing position of the first sealing structure to the rubber strip support body 41.

[0130] In the present embodiment, the distance from the sealing position of the second sealing structure to the rubber strip support body 41 is smaller than the distance from the sealing position of the first sealing structure to the rubber strip support body 41, thereby forming a stepped two-layer sealing system, which on the one hand can prevent the inflow of rainwater when the power water breaks through the first sealing structure; on the other hand, compared with the design of the traditional raised groove structure, the present embodiment forms a descending stepped sealing system extending outward, which can help rainwater discharge and hygienic cleaning.

[0131] Embodiment 10:

[0132] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the first sealing member 431 is a first sealing protrusion; the first sealing fitting member is a first sealing surface; wherein the first sealing protrusion and the first sealing surface form a first sealing structure through a first interference fit.

[0133] In this embodiment, the first sealing component 431 of the outward-opening door and window sealing strip 4 adopts a first sealing protrusion, and the corresponding first sealing mating component configured on the outward-opening door and window frame profile structure 21 is a first sealing surface. The first sealing protrusion is abutted against the first sealing surface to form a first sealing structure to provide a first layer of sealing and blocking for external rainwater.

[0134] In actual application, the first sealing surface is configured as the surface of the first position of the outward-opening door and window frame profile structure 21. Since the outward-opening door and window sealing strip 4 is connected to the outward-opening door and window sash body profile structure and moves with the outward-opening door and window sash body profile structure, when performing the window closing action, the outward-opening door and window sash body profile structure rotates around the rotation axis close to the outward-opening door and window frame profile structure 21. Therefore, the first sealing protrusion of this embodiment is configured to be perpendicular or substantially perpendicular to the first sealing surface when the outward-opening door and window sash body profile structure and the outward-opening door and window frame profile structure 21 are closed. In addition, the first sealing protrusion and the first sealing surface are abutted by interference fit, thereby, through the position driving of the first sealing member 431 by the outward-opening door and window sash body profile structure and the squeezing of the first sealing member 431 by the outward-opening door and window frame profile structure 21, a relatively firm first sealing structure is realized to prevent the breakthrough and inflow of rainwater with a certain kinetic energy or less. The first sealing protrusion is abutted against the first sealing surface to form a first sealing structure to perform a first layer of sealing and blocking of external rainwater. In a preferred embodiment, the first sealing protrusion is generally a protruding sheet-shaped rubber strip.

[0135] Embodiment 11:

[0136] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the first sealing component 431 is a first sealing protrusion; the first sealing matching component is a first sealing surface; wherein the protruding direction of the first sealing protrusion points to the first sealing surface, and an isobaric channel is left between the first sealing protrusion and the first sealing surface to form a first sealing structure.

[0137] In this embodiment, the first sealing component 431 of the outward-opening door and window sealing strip 4 adopts a first sealing protrusion, and the corresponding first sealing mating component configured on the outward-opening door and window frame profile structure 21 is a first sealing surface. The first sealing protrusion pointing to the first sealing surface and the isobaric channel formed by the first sealing surface are used to achieve an isobaric setting with the external space.

[0138] In practical applications, although the first sealing structure using interference fit proposed in the above-mentioned embodiment can seal and block kinetic water with a certain kinetic energy by "blocking", in some cases, the door and window system may also face kinetic water with greater kinetic energy (for example, when there is strong wind pressure on the outdoor side, the outdoor atmospheric pressure is greater than the air pressure of the sealed space formed by the first sealing structure and the second sealing structure). At this time, the first sealing structure cannot effectively waterproof and seal the kinetic water by "blocking", especially considering the outward-opening door and window sealing strip 4 around the outward-opening door and window sash profile structure, the sealed space formed inside is an annular space. If the first sealing structure adopts a tight-fitting interference fit, if kinetic water enters the upper part of the annular space, it will flow to the lower part of the annular space and cannot be discharged.

[0139] Therefore, unlike the above-mentioned embodiment, this embodiment forms an isobaric channel between the first sealing protrusion and the first sealing surface by setting the first sealing structure so that the first sealing protrusion is close to but not close to the first sealing surface. Under the premise of blocking the entry of kinetic energy water to a certain extent, the isobaric channel forms equal pressure between the inner and outer spaces, opens the drainage channel, and can discharge rainwater entering the sealed space, that is, the drainage of rainwater entering the annular space is achieved by "draining", which improves the waterproof effect of the door and window system, can change the current situation that the hardware channels in the traditional outward-opening door and window system are easily subject to electrochemical corrosion due to rainwater or humid environment, provide sufficient watertight protection for the hardware, and increase the product life.

[0140] Embodiment 12:

[0141] One of the optional implementation schemes of the extremely narrow frame outward-opening door and window system, wherein the second outer frame 21 comprises a second outer frame 21 profile body having a second outer frame installation surface 211 and a second outer frame functional surface 212; wherein the second outer frame installation surface 211 is the first surface of the outer frame of the second outer frame 21 profile body, which is used for connecting to a building body and / or connecting to a preassembled body connected to a building body; wherein the second outer frame functional surface 212 is the second surface of the outer frame of the second outer frame 21 profile body; and the first sealing surface is configured as the second outer frame functional surface 212.

[0142] In this embodiment, the second outer frame 21 can be described as follows: the second outer frame installation surface 211 points downward, and can be divided into a surface connected to the basic profile frame or a surface connected to the building according to different installation forms. The second outer frame installation surface 211 refers to the surface of the second outer frame 21 facing upward, which serves as the first sealing surface for forming the first sealing structure. Thus, through the cooperation between the first sealing surface and the first sealing protrusion, the first sealing structure is formed when the outer-opening door and window sash profile structure performs the window closing action, providing the first seal for the outer-opening door and window system.

[0143] Embodiment 13:

[0144] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the second sealing member 432 is a second sealing protrusion; the second sealing fitting is a second sealing surface; wherein the second sealing protrusion and the second sealing surface form a second sealing structure through a second interference fit.

[0145] In this embodiment, the second sealing member 432 of the outward-opening door and window sealing strip 4 adopts a second sealing protrusion, and the corresponding second sealing mating member configured on the outward-opening door and window frame profile structure 21 is a second sealing surface. The second sealing protrusion is used to abut against the second sealing surface to form a second sealing structure to provide a second layer of sealing and blocking for rainwater that breaks through the first sealing structure. In a preferred embodiment, the second sealing protrusion can adopt a protruding structure of any shape, for example, it can be a protruding sheet-like strip, or it can be a strip of any shape protruding toward the second sealing surface.

[0146] In actual application, the second sealing surface is configured as the surface of the second position of the outward-opening door and window frame profile structure 21. Since the outward-opening door and window sealing strip 4 is connected to the outward-opening door and window sash profile structure and moves with the outward-opening door and window sash profile structure, when the window closing action is performed, the outward-opening door and window sash profile structure rotates around the rotation axis close to the outward-opening door and window frame profile structure 21, and the distance from the sealing position of the second sealing structure to the strip support body 41 is smaller than the distance from the sealing position of the first sealing structure to the strip support body 41. Therefore, the second sealing protrusion can be configured to be perpendicular to the first sealing surface or to be in close contact with the first sealing surface at any angle when the outward-opening door and window sash profile structure and the outward-opening door and window frame profile structure 21 are closed. In addition, the second sealing protrusion is abutted against the second sealing surface by interference fit, thereby, a relatively strong second sealing structure is realized through the position driving of the second sealing member 432 by the profile structure of the outward-opening door and window sash body and the extrusion of the second sealing member 432 by the profile structure 21 of the outward-opening door and window frame. The distance from the sealing position of the second sealing structure to the rubber strip support body 41 is smaller than the distance from the sealing position of the first sealing structure to the rubber strip support body 41, further blocking rainwater that enters after breaking through the first sealing structure. The sealing performance of the system is improved. At the same time, on the other hand, compared with the multiple protrusion groove sealing structures set in the traditional door and window system, this embodiment also solves the problems of drainage and sanitation.

[0147] Embodiment 14:

[0148] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the interference amount of the second interference fit is greater than the interference amount of the first interference fit; and the first sealing structure and the second sealing structure form a sealed space with an internal air pressure greater than the atmospheric pressure when performing the window closing action.

[0149] In the present embodiment, the interference fit between the second sealing protrusion and the second sealing surface is greater than the interference fit between the first sealing protrusion and the first sealing surface. Thus, the integrated rubber strip forms an airtight space in the first and second sealing cavities. This enclosed space will form a certain positive pressure due to the squeezing of the sealing strip when the window is closed. When the positive pressure acts on the gap between the first sealing strip and the window body, it can further block the entry of water through the gap, which can change the current situation in which the hardware channels in the traditional outward-opening door and window system are easily susceptible to electrochemical corrosion due to rain or humid environment, provide sufficient watertight protection for the hardware, and improve product life.

[0150] Embodiment 15:

[0151] One of the optional implementation schemes of the extremely narrow frame outward-opening door and window system, the outward-opening door and window sash profile structure, also includes: a first connecting bridge 13 having a first thermal break connecting portion 42131; wherein the first thermal break connecting portion 42131 is configured to be connectable to the first inner frame 12 and / or the first outer frame 11 of the outward-opening door and window sash profile structure; wherein the first connecting bridge 13 has a first thermal break functional surface 132; the first thermal break functional surface 132 is configured with a connecting fitting portion 133, and the connecting fitting portion 133 is used to connect to the connecting portion 42 of the outward-opening door and window sealing strip 4.

[0152] Embodiment 16:

[0153] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the outward-opening door and window frame profile structure 21 also includes: a second connecting bridge 23 having a second thermal break connecting portion 42231; wherein the second thermal break connecting portion 42231 is configured to be connectable to the second inner frame 22 and / or the second outer frame 21 of the outward-opening door and window frame profile structure 21; wherein the second connecting bridge 23 has a second thermal break functional surface 232; and the second sealing surface is configured on the second thermal break functional surface 232.

[0154] In the above-mentioned embodiments 15 and 16, a first connecting bridge 13 having a first thermally broken bridge connecting portion 42131 is arranged between the first inner frame 12 and the first outer frame 11 of the outward-opening door and window sash profile structure, and a second connecting bridge 23 having a second thermally broken bridge connecting portion 42231 is arranged between the second inner frame 22 and the second outer frame 21 of the outward-opening door and window frame profile structure 21; the connecting matching portion 133 of the first connecting bridge 13 is connected to the connecting portion 42 of the sealing strip, and the second sealing surface of the second connecting bridge 23 is connected to the second sealing member 432 of the sealing strip to form a sealing structure, thereby fixing the inwardly moved sealing strip and forming a second sealing structure together with the outward-opening door and window sealing strip 4, thereby blocking rainwater that breaks through the first sealing structure and improving the overall sealing of the outward-opening door and window system.

[0155] Compared with the thermal break structure in the traditional outward-opening door and window system, this embodiment sets a connecting matching part 133 on the first thermal break functional surface 132, and uses the connecting matching part 133 to connect with the connecting part 42 configured with the outward-opening door and window sealing strip 4, so as to achieve fixed connection of the sealing strip; sets a second sealing surface on the second thermal break functional surface 232, and uses the second sealing surface and the second sealing member 432 configured with the sealing strip to form a sealing structure; at the same time, it can drive the sealing strip to follow the movement of the outward-opening door and window sash body profile structure. When the outward-opening door and window sash body profile structure performs the window opening action away from the outward-opening door and window frame profile structure 21, the sealing strip follows the first connecting bridge 13 to perform the action away from the outward-opening door and window frame profile structure 21. When the outward-opening door and window sash body profile structure performs the window closing action close to the outward-opening door and window frame profile structure 21, the sealing strip follows the first connecting bridge 13 to approach the outward-opening door and window frame profile structure 21 to form a sealing structure. In this way, the sealing strip is fixed to the broken bridge structure for connecting the outer frame and the inner frame, and the broken bridge structure and the sealing strip are used to form a second sealing structure to block rainwater that breaks through the first sealing structure.

[0156] Thus, a first sealing structure is formed by the cooperation between the second outer frame functional surface 212 and the outward-opening door and window sealing strip 4, and a second sealing structure is formed by the cooperation between the broken bridge structure and the outward-opening door and window sealing strip 4, thereby providing better watertight protection for various hardware parts arranged in the hardware channels. This can change the current situation in which the hardware channels in traditional outward-opening door and window systems are easily susceptible to electrochemical corrosion due to rain or humid environments, provide sufficient watertight protection for the hardware, and improve product life.

[0157] Embodiment 17:

[0158] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the second connecting bridge 23 comprises: a middle sealing slope surface 234 having a slope bottom 2341, a slope top 2342 and a slope connecting surface 2343; the middle sealing slope surface 234 is arranged on the second thermal insulation functional surface 232; wherein the middle sealing slope surface 234 is configured to connect the second inner frame functional surface 222 and the second outer frame functional surface 212; the slope bottom 2341 is connected to the second outer frame functional surface 212; the slope top 2342 is connected to the second inner frame functional surface 222; wherein the slope connecting surface 2343 is a surface connecting the slope bottom 2341 and the slope top 2342.

[0159] In this embodiment, the second connecting bridge 23 is used to connect the second inner frame 22 and the second outer frame 21 of the outward-opening door and window frame profile structure 21. A middle sealing slope 234 having a slope bottom 2341, a slope top 2342 and a slope connecting surface 2343 is configured on the second connecting bridge 23. The slope bottom 2341 and the slope top 2342 are used to form a middle sealing slope 234 with a high and low drop structure. In actual applications, such a high and low drop structure can block rainwater that breaks through the first sealing structure so that it will not flow directly to the second sealing structure, thereby reducing the watertight pressure of the second sealing structure.

[0160] Embodiment 18:

[0161] In one optional implementation scheme of the extremely narrow frame outward-opening door and window system, the second sealing surface is configured on the slope connecting surface 2343.

[0162] In this embodiment, the slope connection surface 2343 is a connection surface connecting the slope top 2342 and the slope bottom 2341, so the slope connection surface 2343 is usually a non-horizontal surface such as an inclined surface or a vertical surface. In practical applications, the second sealing surface can be set on the slope connection surface 2343, and the second sealing member 432 of the outward-opening door and window sealing strip 4 is set at a position corresponding to the slope connection surface 2343, so that the sealing position of the sealing structure formed by the second sealing surface and the second sealing member 432 is higher than the plane corresponding to the slope bottom 2341. Therefore, when the height difference structure such as the middle sealing slope surface 234 is used to block and collect rainwater that breaks through the first sealing structure, it is not easy for rainwater to enter the sealing structure formed on the slope connection surface 2343, which can further alleviate the watertight pressure of the second sealing structure and prevent rainwater from entering the indoor side. It can change the current situation that the hardware channel in the traditional outward-opening door and window system is easily corroded by electrochemical corrosion due to rainwater or humid environment, provide sufficient watertight protection for hardware, and improve product life.
