Description

Technical Field

[0001] The utility model belongs to the technical field of inward-tilted 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-tilted and side-sliding doors and windows, and specifically relates to a fixed lower rail for an inward-tilted and side-sliding door and window and an inward-tilted and side-sliding door and window system. Background Art

[0002] The tilt-and-slide 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 tilt-and-slide window operates the handle of the window sash to drive the internal linkage hardware structure, so that the window sash can be in three different states: tilt-and-slide, slide-and-lock, 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 inward-tilted side-sliding 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 a reset operation, 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 and airtight 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.

[0065] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0066] See also Figures 1 to 10 As shown, the specific embodiments provided by the utility model are as follows:

[0067] like Figures 1 to 3 As shown, the first embodiment of the utility model provides a fixed lower rail 1301 for an inward tilting and sliding door and window, comprising:

[0068] A first profile 1 having a first end surface 101;

[0069] A second profile 2 having a second end surface 201;

[0070] Bridge connector 3;

[0071] The bridge connection member 3 is connected to the first end surface 101 and the second end surface 201;

[0072] Wherein, the second profile 2 has a first mounting surface 401 and a second mounting surface 402;

[0073] In the first direction, a height H1 of the first mounting surface 401 is greater than a height H2 of the second mounting surface 402;

[0074] Furthermore, the axis L1 of the first mounting surface 401 and the axis L2 of the second mounting surface 402 are not coaxial;

[0075] Furthermore, the first mounting surface 401 is perpendicular to the first direction;

[0076] The second mounting surface 402 is perpendicular to the first direction;

[0077] The first direction is the direction from the fixed lower rail 1301 of the tilt-and-slide door and window to the window glass.

[0078] In this embodiment, the first profile 1 is the portion close to the outdoor side, and the second profile 2 is the portion close to the indoor side.

[0079] Among them, for the first profile 1, its first end face 101 is the surface of the first profile 1 facing the indoor side, and faces the second end face 201 of the second profile 2, and the second end face 201 is the surface of the second profile 2 facing the outdoor side. The first end face 101 and the second end face 201 separate the first profile 1 and the second profile 2 from each other, and can be clamped into a fixed lower rail 1301 as a whole through a bridge connector 3 (referring to a heat-insulating bridge made of heat-insulating material).

[0080] The second profile 2 has a first mounting surface 401 and a second mounting surface 402. The second mounting surface 402 is used to provide a mounting position for the drift sliding assembly 5, and the first mounting surface 401 is used to provide a mounting position for the locking member 6.

[0081] On the basis of the above, in order to further avoid interference between the drift sliding assembly 5 and the locking member 6, the axes of the first mounting surface 401 and the second mounting surface 402 are not coaxial. In other words, the first mounting surface 401 and the second mounting surface 402 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 5 and the locking member 6 are independent of each other and there is no interference.

[0082] Furthermore, the first mounting surface 401 and the second mounting surface 402 are not coplanar. The reason is that, in the height direction along the second profile 2, a certain overlap or staggered existence of the first mounting surface 401 and the second mounting surface 402 is allowed, that is, the orthographic projections of the first mounting surface 401 and the second mounting surface 402 partially overlap, thereby increasing the areas of the first mounting surface 401 and the second mounting surface 402 as much as possible while avoiding interference between the drift sliding component 5 and the locking component 6, thereby ensuring that sufficient installation space is provided for the drift sliding component 5 and the locking component 6.

[0083] That is to say, the fixed lower rail 1301 of the inward-tilted sliding door and window provided in this embodiment can realize the independent installation of the drift sliding assembly 5 and the locking member 6 on the fixed lower rail 1301 by setting two non-staggered installation surfaces, namely the first installation surface 401 and the second installation surface 402, 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 5 and the locking member 6, thereby improving the wind pressure resistance of the inward-tilted sliding door and window. Moreover, since the locking member 6 provides a locking force, the sealing and heat insulation performance of the inward-tilted sliding door and window is also improved.

[0084] In a specific embodiment, the first profile 1 and the second profile 2 are frame structures and are made of aluminum alloy.

[0085] In a specific embodiment, the distance between the first end surface 101 and the second end surface 201 is 17.5 mm. The overall width of the first profile 1 and the second profile 2 in the coupled state is 110 mm.

[0086] The second embodiment of the utility model provides a fixed lower rail 1301 for an inward tilting and sliding door and window, and based on the first embodiment, the first mounting surface 401 has a width W1;

[0087] The second mounting surface 402 has a width W2;

[0088] And, W1=K1*W2;

[0089] K1 is the proportionality coefficient.

[0090] In this embodiment, the width of the first mounting surface 401 and the width of the second mounting surface 402 are limited.

[0091] The reason is that the first mounting surface 401 is functional, that is, it is necessary to provide an installation position for the locking component 6. Therefore, it is necessary to ensure that the first mounting surface 401 can meet the installation requirements of the locking component 6 and improve the connection performance between the two.

[0092] Moreover, both the first mounting surface 401 and the second mounting surface 402 are subjected to stress, and when the door and window are locked, both the first mounting surface 401 and the second mounting surface 402 are stress-bearing surfaces. In other words, both the first mounting surface 401 and the second mounting surface 402 have a problem of large stress concentration.

[0093] Based on this, if the width W2 of the second mounting surface 402 is significantly smaller than the width W1 of the first mounting surface 401, the following problems may occur:

[0094] Stress concentration problem: The large width difference leads to uneven stress distribution on the first mounting surface 401 and the second mounting surface 402. 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 401, which may cause material fatigue and damage, and reduce the overall strength and life of the door and window system.

[0095] 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 402 and the narrower first mounting surface 401. 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 problem of doors and windows falling off.

[0096] 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.

[0097] Installation tolerance problem: The wider second installation surface 402 may require stricter tolerance control during installation to ensure matching with the drift sliding assembly 5 and the locking member 6. A larger installation width increases the complexity of processing and installation, requires higher precision, and increases manufacturing costs and installation difficulty.

[0098] 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.

[0099] If the width W2 of the second mounting surface 402 is significantly greater than the width W1 of the first mounting surface 401, the following problems may occur:

[0100] Insufficient structural strength: The first mounting surface 401 with a smaller width may not provide sufficient structural strength to fix the locking member 6. This may cause the locking member 6 to loosen or fall off during use, thereby affecting the locking function and safety of the door and window.

[0101] Insufficient bearing capacity: The narrow first mounting surface 401 may not be able to effectively disperse the force applied to the locking member 6, 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 6 cannot be ensured.

[0102] 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.

[0103] 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 401 and the second mounting surface 402 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 5 and the locking member 6.

[0104] Specifically, when the value of K1 is close to 0.8, the width of the first mounting surface 401 is relatively small, but still within a reasonable range, which can ensure the installation and use stability of the locking component 6; when the value of K1 is close to 1.2, the width of the first mounting surface 401 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.

[0105] Through the above design, the fixed lower rail 1301 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.

[0106] The third embodiment of the utility model provides a fixed lower rail 1301 for an inward tilting and sliding door and window, and based on the previous embodiment, the first mounting surface 401 is recessed in a direction opposite to the first direction to form a first assembly groove 701;

[0107] The second mounting surface 402 is recessed in a direction opposite to the first direction to form a second assembly groove 702 .

[0108] In this embodiment, the arrangement of the first assembly groove 701 and the second assembly groove 702 further optimizes the structural design of the inward tilting and sliding door and window fixing lower rail 1301. By respectively arranging assembly grooves on the first mounting surface 401 and the second mounting surface 402, it is possible to better meet the installation requirements of different components and improve the stability and reliability of the overall structure.

[0109] Specifically, the second assembly groove 702 is provided so that the drift sliding assembly 5 can be stably mounted on the second mounting surface 402. The drift sliding assembly 5 is closely matched with the second mounting surface 402 through the second assembly groove 702 to achieve smooth sliding operation. The design of the second assembly groove 702 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.

[0110] The first assembly groove 701 is provided so that other components except the drift sliding component 5 can be stably mounted on the first mounting surface 401. The first assembly groove 701 provides mounting positions for multiple components, such as the locking member 6, the sealing structure, etc. Through the design of the first assembly groove 701, the locking points and sealing performance of the doors and windows can be increased without affecting the operation of the sliding components, thereby further improving the wind pressure resistance and heat insulation performance of the doors and windows.

[0111] In practical applications, the first assembly groove 701 and the second assembly groove 702 can be customized according to the size and shape of specific components. For example, the width and depth of the second assembly groove 702 can be adjusted according to the size of the drift sliding component 5 to ensure that the sliding component slides stably in the groove; the size and shape of the first assembly groove 701 can be designed according to the installation requirements of the locking member 6 and other components to ensure that each component can be stably installed and perform its function.

[0112] In addition, the design of the first assembly groove 701 and the second assembly groove 702 can also simplify the installation process to a certain extent. During the production process, the first profile 1 and the second profile 2 can be manufactured by a one-time molding method of a mold, and the positions of the first assembly groove 701 and the second assembly groove 702 can be reserved during the molding process. This not only improves production efficiency, but also ensures the consistency of product quality.

[0113] Through the above design, the fixed lower rail 1301 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 5 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.

[0114] Therefore, by respectively providing assembly grooves on the first mounting surface 401 and the second mounting surface 402, stable installation of the drift sliding component 5 and other components is achieved, thereby improving the stability and reliability of the overall structure.

[0115] The second assembly groove 702 provides a smooth sliding channel for the drift sliding assembly 5, protecting the sliding assembly from damage caused by external impact or environmental factors.

[0116] The first assembly groove 701 provides an installation position 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.

[0117] The fourth embodiment of the utility model proposes a fixed lower rail 1301 for an inward tilting and sliding door and window, and based on the previous embodiment, the first end surface 101, the second end surface 201 and the bridge connection member 3 enclose a first cavity 801;

[0118] A heat insulating medium 802 is disposed in the first cavity 801 .

[0119] In this embodiment, the first cavity 801 is provided to further improve the heat insulation performance of the tilt-and-slide door and window. By filling the first cavity 801 with a heat insulation medium 802, indoor and outdoor heat conduction can be effectively blocked to maintain indoor temperature stability.

[0120] Specifically, the heat insulating medium 802 may be made of a material with a low thermal conductivity, such as polyurethane foam, polystyrene foam or other suitable heat insulating materials, to ensure good heat insulating performance.

[0121] The design of the coaxial axis of the heat insulating medium 802 and the axis of the heat insulating bridge ensures the structural unity and functional synergy of the heat insulating medium 802 and the heat insulating bridge. The coaxial axis means that the heat insulating medium 802 and the heat insulating bridge form a continuous insulation layer in the vertical direction, which effectively prevents heat from being conducted through the first cavity 801, thereby further improving the thermal insulation performance of the doors and windows. By ensuring that the insulation line (referring to the virtual line that blocks heat formed by the axis of the heat insulating medium 802 and the axis of the heat insulating bridge) is in the same straight line, it can be ensured that the isotherms are also in the same straight line, so that the thermal insulation effect is optimized.

[0122] In practical applications, the heat insulating medium 802 can be filled into the first cavity 801 by injection or foaming after the first cavity 801 is formed. This filling method can ensure that the heat insulating medium 802 is evenly distributed in the first cavity 801 without gaps or discontinuous areas, thereby ensuring the uniformity and consistency of the heat insulating effect.

[0123] Through the above design, the fixed lower rail 1301 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.

[0124] By providing the first cavity 801 and filling it with the heat insulating medium 802, 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.

[0125] Therefore, the axis of the heat insulation medium 802 is designed to be coaxial with the axis of the heat insulation bridge to ensure that the heat insulation line and the isotherm line are in the same straight line, thereby achieving the best heat insulation effect.

[0126] The fifth embodiment of the utility model provides a fixed lower rail 1301 for an inward tilting and sliding door and window, and based on the previous embodiment, the second profile 2 has a third end surface 202;

[0127] The third end surface 202 is away from the second end surface 201 and faces the indoor side;

[0128] The third end surface 202 is parallel to the first direction;

[0129] The third end surface 202 is recessed perpendicular to the first direction and toward the outdoor side to form a third assembly groove 2021 .

[0130] Furthermore, the third assembly slot 2021 has:

[0131] A first stop surface 20211 and a second stop surface 20212;

[0132] Wherein, the first stop surface 20211 and the second stop surface 20212 face each other;

[0133] Furthermore, the first stopping surface 20211 and the second stopping surface 20212 are perpendicular to the first direction.

[0134] In this embodiment, the drift sliding assembly 5 is generally composed of a pulley, a sliding member (including an axle body connected to the pulley) and a cantilever. When the inward tilting and sliding door and window are opened, the cantilever of the drift sliding assembly 5 generally provides support for the door and window. If the door and window are heavy, the load on the cantilever will also increase, and the cantilever is prone to tilting.

[0135] Therefore, the third assembly groove 2021 is added in this embodiment. The end of the shaft body is always located in the third assembly groove 2021 after passing through the pulley. When the cantilever is subjected to a load, the end of the shaft body is limited by the first stop surface 20211 and the second stop surface 20212, thereby sharing the load on the cantilever and ensuring the stability of the drift sliding assembly 5.

[0136] In another specific embodiment, the third assembly groove 2021 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 5, due to factors such as too fast speed after opening and large inertia, the movable window sash and the window frame collide violently, causing damage to the drift moving assembly 5, 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.

[0137] The sixth embodiment of the utility model provides a fixed lower rail 1301 for an inward tilting and sliding door and window, and based on the previous embodiment, the first end surface 101 is formed with a snap-fitting port 1 901;

[0138] The second end surface 201 is formed with a second engagement port 902;

[0139] Furthermore, the bridge connection member 3 is engaged between the first engaging port 901 and the second engaging port 902 .

[0140] In this embodiment, by providing the first engagement port 901 and the second engagement port 902 and engaging the heat insulation bridge therebetween, the heat insulation performance of the fixed lower rail 1301 of the inward tilting and sliding door and window can be effectively enhanced. The axis L3 of the heat insulation bridge is coaxial with the axis L4 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 isotherm, 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.

[0141] In addition, the coaxial design of the locking port 1 901 and the locking port 2 902 ensures the stable installation of the thermal insulation bridge in the fixed lower rail 1301, prevents the position displacement of the thermal insulation bridge due to external force, and further ensures the structural stability of the door and window system and the durability of the thermal insulation effect.

[0142] The seventh embodiment of the utility model proposes a fixed lower rail 1301 for an inward tilting and sliding door and window, and based on the previous embodiment, the end surface of the bridge connecting member 3 facing the window glass is provided with a third engaging port 903;

[0143] Furthermore, the engagement port three 903 is configured to assemble the sealing strip 10 .

[0144] In this embodiment, the engagement port three 903 is used to engage the sealing strip 10 .

[0145] The locking sealing strip 10 is used to prevent rainwater from penetrating into the first mounting surface 401 to corrode the locking member 6 .

[0146] In addition, in the prior art, inward tilting and sliding doors and windows generally have two forms.

[0147] First, the inward tilting and sliding door and window comprises a fixed window 11 and a movable window 12. At this time, the lower end surface of the fixed lower rail 1301 can be directly connected to the door hole wall or the window hole wall.

[0148] Secondly, the inward tilting and sliding door and window includes two parts, the upper part includes a fixed window 11 and a movable window 12, and the lower part includes two fixed windows 11. Therefore, the fourth end face 203 of the fixed lower rail 1301 of the movable window 12, that is, the end face facing the fixed window 11 of the lower part, is used to fix one of the fixed windows 11 of the lower part. And the best way is to achieve the installation of the fixed window 11 without changing the structure of the fixed lower rail 1301. 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.

[0149] Based on this, the fourth end face 203 of the fixed lower rail 1301 is provided with a snap-fit ​​port four 904. It should be noted that no matter which of the above two forms the inward-tilted and side-sliding door and window is, the fourth end face 203 is provided with a snap-fit ​​port four 904. When the inward-tilted and side-sliding door and window is of the first form, the snap-fit ​​port four 904 can be used to connect with the door opening wall or the window opening wall (for example, concrete pouring). When the inward-tilted and side-sliding door and window is of the second form, the snap-fit ​​port four 904 is used to connect with a fixed sash window frame, and the fixed sash window frame further clamps the glass of the fixed window 11 at the lower part. Therefore, when the fixed lower rail 1301 is mass-produced in the factory, there is no need to consider which form of the inward-tilted and side-sliding door and window the customer will choose, and the installation of the second form of the inward-tilted and side-sliding door and window can be completed by adding standardized fixed sash window frames.

[0150] like Figures 4 to 10 As shown, the eighth embodiment of the utility model provides an inward tilting and sliding door and window system, comprising:

[0151] The inward tilting and sliding door and window fixing lower rail 1301 as described in any one of the above embodiments;

[0152] Fixed upper rail 1302;

[0153] Border 1303;

[0154] The frame 1303 connects the fixed lower rail 1301 and the fixed upper rail 1302 of the inward-tilting and sliding door and window into a frame structure.

[0155] Specifically, in the height direction of the window, the upper part of the inward tilting and sliding door and window fixed lower rail 1003 is used to install the movable window 12, and the lower part is used to install the fixed window 11. That is to say, for the movable window 12, its upper end is connected to the upper rail 1302, and its lower end is connected to the inward tilting and sliding door and window fixed lower rail 1301, and the frame 1303 is pulled through along the height direction of the window to connect the horizontal upper rail 1302 and the lower rail 1301 to form a frame structure. Among them, the drift sliding assembly 5 is located between the lower rail 1301 and the glass sash of the fixed movable window 12.

[0156] In this embodiment, all the above-mentioned beneficial effects are achieved, which will not be described in detail here.
