Description

Technical Field

[0001] The invention belongs to the technical field of inward-tilt and side-sliding doors and windows, and relates to a technology for improving the wind pressure resistance, sealing performance and heat insulation performance of inward-tilt and side-sliding doors and windows, and specifically relates to a fixed lower rail for an inward-tilt and side-sliding door and window and an inward-tilt and side-sliding door and window system. Background Art

[0002] The tilt-and-slide door and window is a new window design that uses a multi-axis movable track-changing window sash opening system, which can move the window sash horizontally out of the window frame and slide linearly outside the window frame. This design can not only replace traditional casement windows, but also replace sliding windows, providing a more flexible and convenient use experience. The drift window operates the window sash handle to drive the internal linkage hardware structure, so that the window sash can be in three different states: tilt-and-slide, sideways, and locked. The details are as follows:

[0003] Inward tilt state: When the handle is vertically upward, the window sash tilts inward to provide ventilation and prevent rain from entering.

[0004] Sliding state: When the handle is horizontal, the window sash slides sideways, allowing the window sash to move horizontally out of the window frame to achieve a fully open effect.

[0005] Locked state: When the handle is vertically downward, the window sash is locked to ensure the safety and sealing performance of the window.

[0006] The drift window design currently available on the market can achieve 180° free rotation of the handle, completely avoiding misoperation, and can directly switch to the translation state in the inward-tilted state without the need for resetting operations, solving the problem of difficulty in closing large inward-tilted windows.

[0007] However, there are some problems with the inward-tilted and side-sliding doors and windows in the prior art, which are mainly reflected in the design of the fixed lower rail. Traditional inward-tilted and side-sliding doors and windows can usually only install locking parts on the side frames of the doors and windows, because the fixed lower rail needs to provide a sliding channel for the drift sliding assembly. If the locking parts are also installed on the fixed lower rail, interference between the sliding assembly and the locking parts will occur. This design results in the inward-tilted and side-sliding doors and windows only having two locking points on the side frames, thereby limiting the wind pressure resistance, sealing performance and thermal insulation performance of the doors and windows. Due to the insufficient number of locking points, when encountering strong winds or external forces, the stability and sealing effect of the doors and windows will be affected, reducing the overall performance and service life of the doors and windows. Summary of the invention

[0008] In order to solve the above-mentioned problems in the prior art, the present invention provides a fixed lower rail for an inward-tilt and side-sliding door and window and an inward-tilt and side-sliding door and window system.

DETAILED DESCRIPTION

[0073] 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.

[0074] See also Figures 1 to 10 As shown, the specific embodiments provided by the present invention are as follows:

[0075] like Figures 1 to 3 As shown, the first embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, comprising:

[0076] The first ontology 1 and the second ontology 2;

[0077] Wherein, in the height direction along the first body 1 or the second body 2:

[0078] The first body 1 has a first end surface 101 and a second end surface 102;

[0079] The second body 2 has a third end surface 201 and a fourth end surface 202;

[0080] The first end surface 101 is the wall surface of the first body 1 facing the outdoor side;

[0081] The fourth end surface 202 is the wall surface of the second body 2 facing the indoor side;

[0082] The second end surface 102 and the third end surface 201 face each other;

[0083] Wherein, along the width direction of the first body 1 or the second body 2:

[0084] The second body 2 has a first mounting surface 206 and a second mounting surface 207;

[0085] The first mounting surface 206 is connected to the fourth end surface 202 and extends toward the indoor side;

[0086] The second mounting surface 207 connects the third end surface 201 and the fourth end surface 202;

[0087] Furthermore, the central axis N1 of the first mounting surface 206 and the central axis N2 of the second mounting surface 207 are not coaxial;

[0088] Furthermore, the first mounting surface 206 and the second mounting surface 207 are not coplanar.

[0089] In this embodiment, the first body 1 is the portion close to the outside of the window, and the second body 2 is the portion close to the inside of the window.

[0090] Among them, for the first body 1, its first end face 101 is an external viewing face (the end face that can be seen from the outside), and the first end face 101 is a flat plane. The second end face 102 is the face of the first body 1 facing the indoor side, and faces the third end face 201 of the second body 2, and the third end face 201 is the face of the second body 2 facing the outdoor side. The second end face 102 and the third end face 201 make the first body 1 and the second body 2 form a broken bridge structure, and can be engaged with the heat insulation bridge 7 made of heat insulation material.

[0091] The second body 2 is provided with a first mounting surface 206 and a second mounting surface 207. The first mounting surface 206 is used to provide a mounting position for the drift sliding assembly 3, and the second mounting surface 207 is used to provide a mounting position for the locking member 4.

[0092] On the basis of the above, in order to further avoid interference between the drift sliding assembly 3 and the locking member 4, the central axes of the first mounting surface 206 and the second mounting surface 207 are not coaxial. In other words, the first mounting surface 206 and the second mounting surface 207 are two independent end surfaces, and there is no spatial overlap or interlacing between the two, so that the movements of the drift sliding assembly 3 and the locking member 4 are independent of each other and there is no interference.

[0093] Furthermore, the first mounting surface 206 and the second mounting surface 207 are not coplanar. The reason is that, in the height direction along the second body 2, a certain overlap or staggered existence of the first mounting surface 206 and the second mounting surface 207 is allowed, that is, the orthographic projections of the first mounting surface 206 and the second mounting surface 207 partially overlap, thereby increasing the areas of the first mounting surface 206 and the second mounting surface 207 as much as possible while avoiding interference between the drift sliding component 3 and the locking component 4, thereby ensuring that sufficient installation space is provided for the drift sliding component 3 and the locking component 4.

[0094] That is to say, the fixed lower rail 1003 of the inward-tilted sliding door and window provided in this embodiment can realize the independent installation of the drift sliding assembly 3 and the locking member 4 on the fixed lower rail 1003 by setting two non-staggered installation surfaces, namely the first installation surface 206 and the second installation surface 207, thereby at least increasing the locking point of the inward-tilted sliding door and window on the lower side, and there is no motion interference between the drift sliding assembly 3 and the locking member 4, thereby improving the wind pressure resistance of the inward-tilted sliding door and window. Moreover, since the locking member 4 provides a locking force, the sealing and heat insulation performance of the inward-tilted sliding door and window is also improved.

[0095] In a specific embodiment, the first body 1 and the second body 2 are frame structures and are made of aluminum alloy.

[0096] In a specific embodiment, the distance between the first end face 101 and the second end face 102 is 17.5 mm, and the distance between the first end face 101 and the fourth end face 202 is 75 mm. The overall width of the first body 1 and the second body 2 in the coupled state is 110 mm.

[0097] In a specific embodiment, the maximum height of the first end surface 101 is 74 mm, and the height of the second body 2 is 51 mm.

[0098] The second embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, and based on the first embodiment, the first mounting surface 206 has a width W1;

[0099] The second mounting surface 207 has a width W2;

[0100] And, W2=K1*W1;

[0101] K1 is the proportionality coefficient.

[0102] In this embodiment, the width of the first mounting surface 206 and the width of the second mounting surface 207 are limited.

[0103] The reason is that the second mounting surface 207 is functional, that is, it is necessary to provide an installation position for the locking component 4. Therefore, it is necessary to ensure that the second mounting surface 207 can meet the installation requirements of the locking component 4 and improve the connection performance between the two.

[0104] Moreover, both the first mounting surface 206 and the second mounting surface 207 are subjected to stress, and when the door and window are locked, both the first mounting surface 206 and the second mounting surface 207 are stress-bearing surfaces. In other words, both the first mounting surface 206 and the second mounting surface 207 have a problem of large stress concentration.

[0105] Based on this, if the width W2 of the second mounting surface 207 is significantly greater than the width W1 of the first mounting surface 206, the following problems may occur:

[0106] Stress concentration problem: The large width difference leads to uneven stress distribution on the first mounting surface 206 and the second mounting surface 207. When the door and window system is subjected to external forces (such as wind pressure, opening and closing force, etc.), stress is concentrated on the narrower first mounting surface 206, which may cause material fatigue and damage, and reduce the overall strength and life of the door and window system.

[0107] Structural deformation risk: Due to the large width difference, under stress, there will be significant differences in the stress and deformation behavior between the wider second mounting surface 207 and the narrower first mounting surface 206. This may lead to the incoordination of the overall structure, local deformation, affecting the normal opening and closing of doors and windows, and more seriously, significantly reducing the wind pressure resistance of doors and windows, which can easily cause the doors and windows to fall off.

[0108] Inconsistent thermal expansion: Mounting surfaces of different widths may have different thermal expansion behaviors when the temperature changes. Large width differences may lead to inconsistent thermal expansion, resulting in thermal stress, which in turn causes structural deformation or loosening of connecting parts, affecting the sealing performance and thermal insulation effect of doors and windows.

[0109] Installation tolerance problem: The wider second installation surface 207 may require stricter tolerance control during installation to ensure matching with the sliding assembly and the locking member 4. A larger installation width increases the complexity of processing and installation, requires higher precision, and increases manufacturing costs and installation difficulty.

[0110] Aesthetics and design consistency issues: Significant differences in width may undermine the overall aesthetics and design consistency of doors and windows. In architectural design, the appearance and structural consistency of doors and windows are important considerations, and inconsistent widths may affect the overall visual effect and design style.

[0111] If the width W2 of the second mounting surface 207 is significantly smaller than the width W1 of the first mounting surface 206, the following problems may occur:

[0112] Insufficient structural strength: The second mounting surface 207 with a smaller width may not provide sufficient structural strength to fix the locking member 4. This may cause the locking member 4 to loosen or fall off during use, thereby affecting the locking function and safety of the door and window.

[0113] Insufficient bearing capacity: The narrow second mounting surface 207 may not be able to effectively disperse the force applied to the locking member 4, resulting in insufficient local bearing capacity. In particular, when subjected to wind pressure or external force, the narrow mounting surface may be deformed, and the stability of the locking member 4 cannot be ensured.

[0114] Stress concentration problem: Smaller mounting surfaces can lead to stress concentration, especially when subjected to greater forces. This stress concentration can cause material fatigue and breakage, affecting the overall service life of doors and windows.

[0115] Based on this, the range of the proportional coefficient K1 is set to 0.8 to 1.2, ensuring that the widths of the first mounting surface 206 and the second mounting surface 207 vary within a certain range. This design can avoid the above-mentioned deep-seated problems while ensuring the independent installation and normal operation of the drift sliding assembly 3 and the locking member 4.

[0116] Specifically, when the value of K1 is close to 0.8, the width of the second mounting surface 207 is relatively small, but still within a reasonable range, which can ensure the installation and use stability of the locking component 4; when the value of K1 is close to 1.2, the width of the second mounting surface 207 is relatively large, which can provide a larger installation space and better structural strength, thereby ensuring the overall performance of the inward-tilted and sliding door and window system.

[0117] Through the above design, the fixed lower rail 1003 of the inward-tilting and sliding door and window of this embodiment can effectively solve the problems in the prior art and significantly improve the overall performance and service life of the door and window system.

[0118] The third embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, and based on the previous embodiment, the first mounting surface 206 is concave along its height direction to form a first structural groove 501;

[0119] Furthermore, the first structural groove 501 is used to assemble the drift sliding assembly 3 of the inward tilting and sliding door and window;

[0120] The second mounting surface 207 is concave along its height direction to form a second structural groove 502;

[0121] Furthermore, the second structural groove 502 is used to assemble the various components of the inward-tilting and sliding door and window drift-excluding sliding component 3 .

[0122] In this embodiment, the arrangement of the first structural groove 501 and the second structural groove 502 further optimizes the structural design of the inward tilting and sliding door and window fixing lower rail 1003. By respectively arranging structural grooves on the first mounting surface 206 and the second mounting surface 207, it is possible to better meet the installation requirements of different components and improve the stability and reliability of the overall structure.

[0123] Specifically, the arrangement of the first structural groove 501 enables the drift sliding assembly 3 to be stably mounted on the first mounting surface 206. The drift sliding assembly 3 is closely matched with the first mounting surface 206 through the first structural groove 501 to achieve smooth sliding operation. The design of the first structural groove 501 not only provides an installation position for the sliding assembly, but also protects the sliding assembly to a certain extent, preventing it from being damaged by external impact or environmental factors.

[0124] The second structural groove 502 is provided so that other components except the drift sliding component 3 can be stably mounted on the second mounting surface 207. The second structural groove 502 provides mounting positions for multiple components, such as the locking member 4, the sealing structure, etc. Through the design of the second structural groove 502, the locking points and sealing performance of the doors and windows can be increased without affecting the operation of the sliding components, and the wind pressure resistance and heat insulation performance of the doors and windows can be further improved.

[0125] In practical applications, the first structural groove 501 and the second structural groove 502 can be customized and designed according to the size and shape of specific components. For example, the width and depth of the first structural groove 501 can be adjusted according to the size of the sliding component to ensure that the sliding component slides stably in the groove; the size and shape of the second structural groove 502 can be designed according to the installation requirements of the locking member 4 and other components to ensure that each component can be stably installed and perform its function.

[0126] In addition, the design of the first structural groove 501 and the second structural groove 502 can also simplify the installation process to a certain extent. During the production process, the first body 1 and the second body 2 can be manufactured by a one-time molding method of the mold, and the positions of the first structural groove 501 and the second structural groove 502 can be reserved during the molding process. This not only improves production efficiency, but also ensures the consistency of product quality.

[0127] Through the above design, the fixed lower rail 1003 of the inward tilting and sliding door and window of this embodiment is further optimized in structure, and the stable installation of the drift sliding component 3 and other components is achieved, which significantly improves the overall performance of the door and window system. Especially under severe weather conditions, it can effectively enhance the wind pressure resistance and heat insulation performance of the doors and windows, and improve the comfort and safety of the living environment.

[0128] Therefore, by respectively arranging structural grooves on the first mounting surface 206 and the second mounting surface 207, stable installation of the drift sliding component 3 and other components is achieved, thereby improving the stability and reliability of the overall structure.

[0129] The first structural groove 501 provides a smooth sliding channel for the drift sliding component 3, protecting the sliding component from damage caused by external impact or environmental factors.

[0130] The second structural groove 502 provides installation positions for other components, increases the locking points and sealing performance of the doors and windows, and further improves the wind pressure resistance and heat insulation performance of the doors and windows.

[0131] The fourth embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, and based on the previous embodiment, the vertical distance between the first mounting surface 206 and the lower edge of the inward tilting and sliding door and window is L1;

[0132] The vertical distance between the second mounting surface 207 and the lower edge of the inward tilting and sliding door and window is L2;

[0133] Moreover, L1>L2.

[0134] In this embodiment, the vertical distance between the first mounting surface 206 and the lower edge of the inward-tilted sliding door and window is set to L1, and the vertical distance between the second mounting surface 207 and the lower edge of the inward-tilted sliding door and window is set to L2, and L1 is ensured to be greater than L2. The purpose is to optimize the installation position and operating performance of the drift sliding assembly 3 and the locking component 4.

[0135] Specifically, since the vertical distance (L1) between the first mounting surface 206 and the lower edge of the tilt-in sliding door and window is longer, a larger mounting space and better structural stability can be provided, and such a design helps the drift sliding assembly 3 to be smoother and more stable during installation and operation. In addition, the longer vertical distance L1 also helps to provide more adjustment space during the installation of the sliding assembly, thereby improving the installation accuracy and stability of the sliding assembly.

[0136] On the other hand, the vertical distance between the second mounting surface 207 and the lower edge of the inward-tilted sliding door and window is relatively short (L2). This design is mainly to ensure that the locking member 4 can more firmly fix the inward-tilted sliding door and window. The shorter vertical distance allows the locking member 4 to fit the inward-tilted sliding door and window more closely, thereby providing a stronger locking force and enhancing the wind pressure resistance and sealing performance of the inward-tilted sliding door and window. This design can not only effectively lock the door and window, but also resist the influence of external environmental factors (such as wind pressure, rain, etc.) on the door and window to a certain extent, thereby improving the service life and safety of the door and window.

[0137] In addition, the design of L1>L2 can also avoid interference between the sliding assembly and the locking member 4. Since the sliding assembly is installed at a higher position and the locking member 4 is installed at a lower position, there will be no collision or friction between the two during operation, thereby ensuring the normal operation of the sliding assembly and the locking member 4. This design further improves the overall operating performance and stability of the inward-tilting and sliding door and window.

[0138] During the specific operation, when the tilt-and-slide door and window needs to slide, the sliding assembly slides on the first mounting surface 206, and the locking member 4 is fixed on the second mounting surface 207, ensuring that the operations of the sliding assembly and the locking member 4 do not interfere with each other; and when the tilt-and-slide door and window needs to be locked, the locking member 4 is fixed through the second mounting surface 207 to provide a strong locking force. The tilt-and-slide door and window designed in this way is not only easy and flexible to operate, but also has high safety and stability.

[0139] Through the above design, this embodiment provides a more optimized structure of the fixed lower rail 1003 of the tilt-in side sliding door and window, ensuring that the installation position of the drift sliding assembly 3 and the locking member 4 is reasonable and the operating performance is excellent. The setting of L1 and L2 not only improves the operating stability and accuracy of the sliding assembly, but also enhances the locking force and wind pressure resistance of the locking member 4, so that the tilt-in side sliding door and window can simultaneously meet the requirements of smooth operation and stable locking during use, significantly improving the overall performance and user experience of the door and window.

[0140] Therefore, by setting different vertical distances (L1 and L2), the installation positions of the drift sliding assembly 3 and the locking member 4 are ensured to be reasonable, thereby improving the operational performance and stability. The longer L1 ensures that the sliding assembly has more installation and adjustment space, thereby improving the installation accuracy and stability. The shorter L2 ensures that the locking member 4 fits tightly, thereby enhancing the wind pressure resistance and sealing performance of the doors and windows. The design of L1>L2 avoids interference between the sliding assembly and the locking member 4, thereby ensuring the normal operation of both and improving the overall operational performance. This design significantly improves the overall performance and user experience of the inward-tilted sliding doors and windows, making them have the advantages of both smooth operation and firm locking.

[0141] The fifth embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, and based on the previous embodiment, the fourth end surface 202 is recessed toward the outdoor side along its width direction to form a third structural groove 503;

[0142] The third structural groove 503 forms a first stop surface 5031 and a second stop surface 5032 along the width direction of the fourth end surface 202;

[0143] Furthermore, the first stopping surface 5031 and the second stopping surface 5032 face each other.

[0144] In this embodiment, the drift sliding assembly 3 is generally composed of a pulley 301, a sliding member 302 (including an axle body connected to the pulley 301) and a cantilever 303. When the inward tilting and sliding door and window are opened, the drift sliding assembly 3 is generally used to provide support for the door and window. If the door and window are heavy, the load on the cantilever 303 of the drift sliding assembly 3 will also increase, and the cantilever 303 is prone to tilting.

[0145] Therefore, the third structural groove 503 is added in this embodiment. The end of the shaft body is always located in the third structural groove 503 after passing through the pulley 301. When the cantilever 303 is subjected to a load, the end of the shaft body is limited by the first stop surface 5031 and the second stop surface 5032, thereby sharing the load on the cantilever 303 and ensuring the stability of the drift sliding assembly 3.

[0146] In another specific embodiment, the third structural groove 503 can also be used to install a buffer accessory (not shown in the figure). Specifically, when the movable window sash is in a side sliding state, that is, when the glass sash slides on the fixed lower rail through the drift sliding assembly 3, due to factors such as too fast speed after opening and large inertia, the movable window sash and the window frame collide strongly, causing damage to the drift moving assembly 3, the window sash or the window frame. The role of the buffer accessory is to absorb or alleviate the collision kinetic energy generated above, thereby effectively protecting each component.

[0147] The sixth embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, and based on the previous embodiment, the second end surface 102 is formed with a snap-fitting port 1 601;

[0148] The third end surface 201 is formed with a second engagement port 602;

[0149] Furthermore, the axis of the first engagement port 601 and the axis of the second engagement port 602 are coaxial;

[0150] Wherein, a heat insulation bridge 7 is clamped between the clamping port 1 601 and the clamping port 2 602;

[0151] Furthermore, the axis N3 of the heat insulation bridge 7 is coaxial with the axis N4 of the heat insulation strip on the outer side of the inward-tilted sliding door and window.

[0152] In this embodiment, by providing the first engagement port 601 and the second engagement port 602 and engaging the heat insulation bridge 7 therebetween, the heat insulation performance of the fixed lower rail 1003 of the inward tilting and sliding door and window can be effectively enhanced. The axis N3 of the heat insulation bridge 7 is coaxial with the axis N4 of the heat insulation strip on the outer side of the inward tilting and sliding door and window, ensuring that the heat insulation line is in the same straight line, improving the consistency of the isothermal line, and thus optimizing the overall heat insulation effect. This design not only improves the energy-saving performance of doors and windows, but also effectively prevents the thermal bridge effect, thereby improving indoor comfort and energy efficiency.

[0153] In addition, the coaxial design of the locking port 1 601 and the locking port 2 602 ensures the stable installation of the insulation bridge 7 in the fixed lower rail 1003, prevents the position displacement of the insulation bridge 7 due to external force, and further ensures the structural stability of the door and window system and the durability of the insulation effect.

[0154] On the basis of the above, the second end surface 102, the insulation bridge 7 and the third end surface 201 enclose a second cavity 802;

[0155] Furthermore, the second cavity 802 is filled with a heat insulating medium 803;

[0156] The axis N5 of the thermal insulation medium 803 and the axis N3 of the thermal insulation bridge 7 are coaxial.

[0157] In this embodiment, the second cavity 802 is provided to further improve the heat insulation performance of the tilt-and-slide door and window. By filling the second cavity 802 with a heat insulation medium 803, indoor and outdoor heat conduction can be effectively blocked to maintain indoor temperature stability.

[0158] Specifically, the second cavity 802 is formed by the second end face 102, the heat insulation bridge 7 and the third end face 201. The heat insulation bridge 7 not only serves as a part of the broken bridge structure, but also further enhances the heat insulation effect by filling the heat insulation medium 803. The heat insulation medium 803 can be made of a material with a low thermal conductivity, such as polyurethane foam, polystyrene foam or other suitable heat insulation materials, to ensure good heat insulation performance.

[0159] The design of the coaxial axis N5 of the heat insulating medium 803 and the axis N3 of the heat insulating bridge 7 ensures the structural unity and functional synergy of the heat insulating medium 803 and the heat insulating bridge 7. The coaxial axis means that the heat insulating medium 803 and the heat insulating bridge 7 form a continuous heat insulating layer in the vertical direction, which effectively prevents heat from being conducted through the second cavity 802, thereby further improving the heat insulating performance of the doors and windows. By ensuring that the heat insulating line (referring to the virtual line that blocks heat formed by the axis N5 of the heat insulating medium 803, the axis N3 of the heat insulating bridge 7, and the axis N4 of the heat insulating strip on the outside of the inward-tilted and side-sliding doors and windows) is in the same straight line, it can be ensured that the isotherms are also in the same straight line, so that the heat insulating effect is optimized.

[0160] In practical applications, the heat insulating medium 803 can be filled into the second cavity 802 by injection or foaming after the second cavity 802 is formed. This filling method can ensure that the heat insulating medium 803 is evenly distributed in the second cavity 802 without gaps or discontinuous areas, thereby ensuring the uniformity and consistency of the heat insulating effect.

[0161] Furthermore, the width of the second cavity is W3>W2 to ensure thermal insulation performance.

[0162] Through the above design, the fixed lower rail 1003 of the inward tilting and sliding door and window of this embodiment is further optimized in structure, which significantly improves the thermal insulation performance of the door and window system. Especially in cold or hot climate conditions, it can effectively reduce the impact of the indoor and outdoor temperature difference on the indoor environment, and improve living comfort and energy efficiency.

[0163] By providing the second cavity 802 and filling it with the heat insulating medium 803, the heat insulating performance of the inward tilting and sliding door and window is significantly improved, the heat conduction loss is reduced, and the indoor temperature is kept stable.

[0164] Therefore, the axis of the heat insulating medium 803 is designed to be coaxial with the axis of the heat insulating bridge 7 to ensure that the heat insulating line and the isothermal line are in the same straight line, thereby achieving the best heat insulating effect.

[0165] The seventh embodiment of the present invention provides a fixed lower rail 1003 for an inward tilting and sliding door and window, and based on the previous embodiment, the first body 1 forms a third engaging port 603 on the side away from the first end surface 101;

[0166] Furthermore, the engagement port 3 603 faces the indoor side;

[0167] The number of the three engaging ports 603 is 1, and in the direction away from the lower edge of the inward-tilted sliding door and window, the end surface M1 of the first body 1 away from the lower edge of the inward-tilted sliding door and window is coplanar with the end surface M2 of the second body 2 away from the lower edge of the inward-tilted sliding door and window;

[0168] Or, the number of the three engaging ports 603 is 2, and they are respectively arranged on the side away from the lower edge of the inward-tilted side sliding door and window and the side close to the lower edge of the inward-tilted side sliding door and window, and in the direction away from the lower edge of the inward-tilted side sliding door and window, the end surface M1 of the first body 1 away from the lower edge of the inward-tilted side sliding door and window and the end surface M2 of the second body 2 away from the lower edge of the inward-tilted side sliding door and window are not coplanar.

[0169] In this embodiment, the engagement port three 603 is used to engage the sealing strip 901 .

[0170] Furthermore, in the prior art, inward tilting and sliding doors and windows generally have two forms.

[0171] First, the inward tilting and sliding door and window includes a fixed window 1001 and a movable window 1002. At this time, the lower end surface of the fixed lower rail 1003 can be directly connected to the door hole wall or the window hole wall, so it is defined that the end surface M1 of the first body 1 away from the lower edge of the inward tilting and sliding door and window and the end surface M2 of the second body 2 away from the lower edge of the inward tilting and sliding door and window are coplanar. In addition, at this time, it is not necessary to provide a seal between the lower end surface of the fixed lower rail 1003 and the door hole wall or the window hole wall, so the number of the engaging port three 603 can be set to 1 to ensure the sealing performance of the door and window system when the movable window 1002 is closed.

[0172] Secondly, the inward tilting and sliding door and window includes two parts, the upper part includes a fixed window 1001 and a movable window 1002, and the lower part includes two fixed windows 1001. Therefore, the fifth end face 203 of the fixed lower rail 1003 of the movable window 1002, that is, the end face facing the fixed window 1001 of the lower part, is used to fix one of the fixed windows 1001 of the lower part. And the best way is to achieve the installation of the fixed window 1001 without changing the structure of the fixed lower rail 1003. The reason is that when the factory is making it, it is very cost-saving to standardize each structural part. If a variety of structural parts with different structures are required due to different installation conditions, the factory needs to increase production costs.

[0173] Based on this, the fifth end face 203 of the fixed lower rail 1003 is provided with a snap-fit ​​port four 604. It should be noted that no matter which of the above two forms the inward-tilted side-sliding door and window is, the fifth end face 203 is provided with a snap-fit ​​port four 604. When the inward-tilted side-sliding door and window is of the first form, the snap-fit ​​port four 604 can be used to connect with the door opening wall or the window opening wall (for example, concrete pouring). When the inward-tilted side-sliding door and window is of the second form, the snap-fit ​​port four 604 is used to connect with a snap-fit ​​component 605, and the snap-fit ​​component 605 further clamps the glass of the fixed window 1001 at the lower part. Therefore, when the factory mass-produces the fixed lower rail 1003, there is no need to consider which form of the inward-tilted side-sliding door and window the customer will choose, and the installation of the second form of the inward-tilted side-sliding door and window can be completed by adding the snap-fit ​​component 605 produced in a standardized manner. At this time, the number of the locking ports three 603 is two, and the locking port three 603 located at the bottom (close to the lower part of the fixed window 1001) cooperates with the locking component 605 (it is necessary to satisfy the above-mentioned end surface M1 of the first body 1 away from the lower edge of the inward-tilted sliding door and window and the end surface M2 of the second body 2 away from the lower edge of the inward-tilted sliding door and window are not coplanar) to achieve clamping and fixation of the door and window glass.

[0174] In a specific embodiment, the first body 1 and the second body 2 are both produced in a standardized manner. There are two standard models of the first body 1, one is a structural form in which the end surface M1 of the first body 1 away from the lower edge of the inward-tilted sliding door and window and the end surface M2 of the second body 2 away from the lower edge of the inward-tilted sliding door and window are coplanar, and the other is a structural form in which the end surface M1 of the first body 1 away from the lower edge of the inward-tilted sliding door and window and the end surface M2 of the second body 2 away from the lower edge of the inward-tilted sliding door and window are not coplanar. Moreover, the engaging member 605 is a frame structure, and can be engaged with the engaging port 4 604, which is also produced in a standardized manner. The first body 1, the second body 2 and the engaging member 605 can be connected accordingly according to the installation requirements.

[0175] The eighth embodiment of the present invention proposes a fixed lower rail 1003 for an inward-tilting and sliding door and window, and based on the previous embodiment, the second body 2 is formed with a first cavity 801 .

[0176] It is further found that the usual installation method for the fixed lower rail 1003 in the prior art is to set a connector near the indoor side and the outdoor side of the fixed lower rail 1003, such as a mounting bolt, and first connect the mounting bolt to a mounting member, such as a mounting plate, and then connect the mounting plate to the door opening or window opening. The reason is that the fixed lower rail 1003 in the prior art lacks installation space, and it only has a larger width in the sliding channel of the drift sliding assembly 3 (i.e., the first mounting surface 206 of the present application), so as to meet the installation of high-strength bolts. However, if the high-strength bolts are installed at this position, it will interfere with the sliding of the drift sliding assembly 3. Therefore, it can only punch holes and install high-strength bolts in the part of the fixed lower rail 1003 close to the outdoor side (i.e., the part of the first body 1 of the present application close to the outdoor side), and the part of the fixed lower rail 1003 close to the indoor side (i.e., the part of the second body 2 of the present application close to the indoor side). Furthermore, since both the first body 1 and the second body 2 have a certain height, if high-strength bolts are drilled in the direction toward the door hole wall or window hole wall (referring to the wall portion where the door hole or window hole is connected to the fixed lower rail 1003) so that the door hole wall or window hole wall is directly connected to the fixed lower rail 1003, the first body 1 and the second body 2 need to be drilled through completely, which significantly reduces the structural strength. Therefore, it is only possible to drill high-strength bolts in the fixed lower rail 1003 in the direction of the door hole wall or window hole wall so that the fixed lower rail 1003 is first connected to the mounting plate, and then the mounting plate is connected to the door hole wall or window hole wall.

[0177] In this embodiment, the first cavity 801 can be used to install high-strength bolts, so that the fixed lower rail 1003 can be directly connected to the door hole wall or window hole wall without the need for a mounting plate. This design avoids structural damage to the first body 1 and the second body 2, and maintains the overall strength and stability of the fixed lower rail 1003.

[0178] like Figures 4 to 10 As shown, the ninth embodiment of the present invention provides an inward tilting and sliding door and window system, comprising:

[0179] The inward tilting and sliding door and window fixing lower rail 1003 as described in any one of the above embodiments;

[0180] Upper track 1004;

[0181] Border 1005;

[0182] The inward-tilting and sliding door and window fixed lower rail 1003, upper rail 1004 and frame 1005 form a frame structure.

[0183] Specifically, in the height direction of the window, the upper part of the fixed lower rail 1003 of the tilt-and-slide door and window is used to install the movable window 1002, and the lower part is used to install the fixed window 1001. That is to say, for the movable window 1002, its upper end is connected to the upper rail 1004, and its lower end is connected to the fixed lower rail 1003 of the tilt-and-slide door and window, and the frame 1005 is pulled through along the height direction of the window to connect the horizontal upper rail 1004 and the lower rail 1003 to form a frame structure. Among them, the drift sliding assembly 3 is located between the lower rail 1003 and the glass sash of the fixed movable window 1002.
