Description

Technical Field

[0001] The present application relates to the technical field of door and window frame structures, and in particular to a door and window movable glass leaf and a door and window glass leaf lower track system. Background Art

[0002] Inward-tilting and side-sliding doors and windows combine the advantages of casement doors and windows and sliding doors and windows. They can achieve micro-ventilation and opening functions through inward tilting and side sliding without occupying indoor space.

[0003] Glass sash refers to window or door sashes equipped with glass, which are mainly used for lighting, ventilation and other functions of buildings. In modern buildings, glass sashes are not only the basic components of windows, but also an important element connecting indoor and outdoor spaces. The design and manufacture of glass sashes involve knowledge in many fields such as architectural aesthetics, structural mechanics, and material science. The quality of its design and installation directly affects the beauty, safety and functionality of the building.

[0004] The glass sash of the inward-tilted and side-sliding doors and windows includes: Glass: The core part of the glass sash, usually made of tempered glass or insulating glass to provide good thermal insulation and sound insulation;

[0005] Fixed frame: It can be aluminum alloy, wood or other synthetic materials, used to install the glass in the door frame or window frame;

[0006] Movable frame: used to fix glass, which can be moved on the fixed frame to open or close doors and windows;

[0007] Hardware accessories: including but not limited to hinges, handles, locks, etc., which are necessary components for controlling the opening and closing of glass sashes and affect the practicality and durability of doors and windows;

[0008] Sealing strip: Mainly used to improve the sealing performance of glass sashes and prevent the penetration of air and moisture.

[0009] There are some design problems in the existing inward-tilting and sliding doors and windows, which are mainly manifested in the structure of the movable glass leaf. Traditional inward-tilting and sliding doors and windows usually install the locking parts at the connection between the fixed lower rail of the glass leaf close to the outdoor side and the movable glass leaf, or at the connection between the screen leaf and the movable glass leaf. The connection between the movable glass leaf and the screen leaf or the fixed lower rail may cause condensation of water droplets and infiltration into the inner side of the glass leaf due to the temperature difference between the inside and outside of the inward-tilting and sliding doors and windows. The locking parts are mostly made of metal, which is prone to rust when in contact with liquids, resulting in a shortened service life of the locking parts. Utility Model Content

[0010] The purpose of the present application is to provide a door and window movable glass sash and a door and window glass sash lower track system to address the above-mentioned problems, which can reduce the probability of rusting of the locking parts, extend the service life of the locking parts, and improve the above-mentioned problems.

[0011] This application is achieved through the following technical solutions:

[0012] In the first aspect, the present application provides a movable glass sash for doors and windows, which can cooperate with a pressure line to clamp the glass, and the movable glass sash for doors and windows includes a first main body and a second main body; the second main body includes a first component and a second component, and the second component is closer to the indoor side than the first component; wherein the first main body is mechanically connected to the first component, and the first main body and the pressure line connected to the second main body cooperate to clamp the glass, and the first main body is closer to the outdoor side than the second main body; in the height direction of the second main body, a first card groove is provided on the side of the first component facing away from the glass, and the first card groove is lower than the first main body.

[0013] In the technical solution of the embodiment of the present application, the first body and the pressure line connected to the second body cooperate to clamp the glass. The first body is closer to the outdoor side than the second body. The second body includes a first component and a second component. The second component is closer to the indoor side than the first component. The first body is mechanically connected to the first component. A first card slot for installing a locking member is provided on the side of the first component away from the glass. The first card slot avoids the drainage cavity for drainage, thereby reducing the risk of liquids such as water condensed on the glass penetrating into the movable glass leaf of the door and window and contacting the locking member through the connection with the glass pressure line or the first body. The first component is located between the first body and the second body. The first body and part of the first component can enclose a cavity (i.e., the drainage cavity hereinafter) for collecting and discharging liquids such as water penetrating into the frame of the glass leaf of the door and window. The position of the first card slot avoids the position of the drainage cavity, thereby reducing the risk of the locking member rusting due to contact with liquids such as water, extending the service life of the locking member, and reducing the frequency of users replacing the locking member, thereby reducing the use cost of the glass leaf of the door and window.

[0014] The first card slot is located close to the indoor side, which reduces the impact of collisions and knocks on the outdoor side on the doors and windows. The temperature of the area close to the indoor side where the first card slot is located can generally be maintained at a relatively mild state, and the temperature is rarely too high or too low, thereby reducing the risk of deformation of the locking part due to thermal expansion and contraction, which causes squeezing of its own components and surrounding components, resulting in deformation of these components, and then causing the coordination effect between the various components of the locking part to deteriorate or even be damaged.

[0015] In some embodiments, an end of the second component facing away from the glass is lower than the first groove, a first surface is formed between the first component and the second component, and the first surface is provided with a second groove protruding from the first surface.

[0016] In the technical solution of the embodiment of the present application, the end of the second component facing away from the glass is lower than the first slot, and the second component can separate the first slot from the room, thereby protecting the locking piece arranged in the first slot from being easily affected by knocks or liquids from the room, thereby extending the service life of the locking piece; a first surface is formed between the first component and the second component, and the first surface is provided with a second slot protruding from the first surface. The second slot can be used to install a sealing piece that separates the installation space of the locking piece corresponding to the first slot from the room, thereby improving the sealing between the first surface and other components, thereby improving the effect of protecting the locking piece from being affected by the indoor environment.

[0017] In some embodiments, in the height direction of the second component, a dimension of the first surface is h, which satisfies 15 mm ≤ h ≤ 30 mm.

[0018] In the technical solution of the embodiment of the present application, in the height direction of the second component, the size of the first surface is h, and the size of h is proportional to the size of the installation space reserved for the locking member in the height direction of the second component. When 15mm≤h≤30mm is satisfied, the size of the installation space reserved for the locking member can meet the strength required for the rated strength of the door and window glass sashes.

[0019] In some embodiments, the first body includes a third component and a fourth component; the third component is closer to the outdoor side than the fourth component, the third component has a second surface facing away from the glass, the fourth component has a third surface facing away from the glass, and the third surface is not flush with the second surface.

[0020] In the technical solution of the embodiment of the present application, the third component can be sealed and connected to the screen fan, and external water and other liquids can penetrate into the frame of the inward-tilted and sliding door and window glass fan through the connection between the third component and the screen fan. The second surface is not flush with the third surface, so that there can be a bending structure between the second surface and the third surface. The liquid can gather at the bending point to form heavier droplets and then drip, reducing the risk of liquid flowing along the first body all the way to the first slot and contacting the locking member.

[0021] In some embodiments, the second surface is higher than the third surface, and the second surface is provided with a protruding first protrusion.

[0022] In the technical solution of the embodiment of the present application, a protruding first protrusion is provided on the second surface, and liquids such as water flowing to the second surface can gather on the first protrusion. When the weight of the liquid on the first protrusion increases to the point where it is difficult to continue to adsorb on the first protrusion, the liquid will drip from the first protrusion, allowing the liquid on the second surface to gather and drip faster, thereby reducing the probability of the liquid flowing through the second surface to the first card slot.

[0023] In some embodiments, the third surface is lower than the second surface, and the third surface is provided with a protruding second protrusion.

[0024] In the technical solution of the embodiment of the present application, the third surface is lower than the second surface, and the third surface is higher than the first card slot, so that the overall thickness of the first main body is thinner, and the cavity inside the assembled door and window glass sash frame is larger. On the one hand, the weight of the door and window glass sash frame is reduced, and the difficulty of installing the door and window glass sash frame is reduced. On the other hand, sufficient space is reserved for the door and window glass sash frame to expand and contract at different temperatures in different seasons; the third surface is provided with a protruding second protrusion, and liquids such as water flowing to the third surface can gather on the second protrusion. When the weight of the liquid on the second protrusion increases to the point that it is difficult to continue to adsorb on the second protrusion, the liquid will drip from the second protrusion, so that the liquid on the third surface can gather and drip faster, thereby reducing the probability of the liquid flowing through the third surface to the first card slot.

[0026] In the technical solution of the embodiment of the present application, the fixed lower rail of the door and window is coupled with the movable glass leaf of the door and window, and the first seal is arranged between the first slot and the fixed lower rail of the door and window; the second seal is arranged between the second component and the fixed lower rail of the door and window, the first seal, the first main body, the second main body and the fixed lower rail of the door and window form a drainage cavity, the first through hole connects the drainage cavity and extends to the outdoor side, the water and other liquids entering the door and window glass leaf frame can be concentrated in the drainage cavity, and then discharged through the first through hole, so that the inner side of the door and window glass leaf frame can be kept in a relatively dry state, reducing the risk of liquid causing the parts of the door and window glass leaf frame to rust or penetrate into the room; the first channel is the installation space reserved for the locking member, the first seal and the second seal respectively block the liquid or gaseous water on the outside and inside of the door and window glass leaf from entering the first channel and contacting the locking member which is generally made of metal, reducing the probability of the locking member in the first channel getting damp and rusted.

[0027] In some embodiments, a third seal is also included, and an extension section is provided at one end of the second component facing away from the glass, and the extension section extends away from the glass along the height direction of the second main body; the third seal is arranged between the extension section and the fixed lower rail of the door and window; the third seal, the fixed lower rail of the door and window, the second seal and the second component form a second channel.

[0028] In the technical solution of the embodiment of the present application, the third seal, the door and window fixed lower rail, the second seal and the second component form a second channel. On the one hand, the extended section can protect the components located in the second channel from being easily affected by the indoor environment; on the other hand, there is a double barrier of the second seal and the third seal between the first channel and the indoor side, thereby improving the protection effect of the locking member in the first channel.

[0029] In some embodiments, the first sealing member has a slope, an end of the slope close to the second body is higher than an end of the slope close to the door and window fixing lower rail, and the lowest point of the slope is closer to the first through hole than the highest point of the slope.

[0030] In the technical solution of the embodiment of the present application, part of the liquid entering the drainage cavity will drip onto the slope surface, then flow along the slope surface at a faster speed toward the first through hole, and then be discharged to the outdoor side of the door and window glass frame, thereby accelerating the speed at which the liquid in the drainage cavity is discharged, and allowing the drainage cavity to be in a dry state for a longer period of time.

[0031] In some embodiments, it also includes a screen fan and a fourth seal. The screen fan is arranged between the fixed lower rail of the door and window and the first main body.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0045] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0048] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0049] The movable glass panels of doors and windows provided in the present application can be applied to various types of doors and windows. The present application is described using inward-tilting and side-sliding doors and windows as an example.

[0050] The inventors of the present invention have noticed that during the use of the inward-tilted and side-sliding doors and windows, since the locking member that controls the movable frame to switch between a fixed position state and a movable state relative to the fixed frame is generally arranged near the connection between the movable frame and the screen fan or the fixed frame, the area is close to the drainage cavity of the glass fan frame, and the locking member is easily in contact with liquids such as water. The locking member is generally made of metal, and the locking member may rust due to contact with water, which shortens the service life of the locking member. Users need to frequently replace the locking member, resulting in an increase in the cost of using the inward-tilted and side-sliding doors and windows.

[0051] Based on the above considerations, in order to alleviate the problem of the locking parts of the inward-tilted and sliding doors and windows being deformed and damaged due to rusting in contact with water or being knocked, extreme temperatures, etc., the inventors have designed, after in-depth research, an inward-tilted and sliding door and window movable glass leaf, comprising a first main body and a second main body, the second main body comprising a first component and a second component, a first card slot being provided on the side of the first component facing away from the glass, the first card slot being used to install the locking part, and by installing the locking part in the first card slot separated from the drainage cavity and close to the indoor side, the risk of the locking part being rusted in contact with water or deformed and damaged by external influences is reduced.

[0052] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of door and window glass sashes provided in some embodiments of the present application, wherein the inward-tilting and sliding door and window glass sashes are arranged on the ground or on a work platform, and the glass sashes include a fixed frame 1, a movable frame 2 and a glass 3, the glass 3 is fixed to the movable frame 2, the movable frame 2 is slidably arranged in the fixed frame 1, and the fixed frame 1 is fixedly installed on the door frame or the window frame.

[0053] Please refer to Figure 1 and Figure 2 The movable frame 2 and the fixed frame 1 are both composed of four sides. The side of the movable frame 2 closest to the ground or the working platform is the movable glass leaf 20 of the door and window, and the side of the fixed frame 1 closest to the ground or the working platform is the fixed lower rail 10 of the door and window.

[0054] According to some embodiments of the present application, optionally, Figure 2 to Figure 7As shown, the present application provides a movable glass leaf 20 for doors and windows, which can cooperate with a pressure line 203 to clamp the glass 3. The movable glass leaf 20 for doors and windows includes a first main body 200 and a second main body 201; the second main body 201 includes a first component 2010 and a second component 2011, and the second component 2011 is closer to the indoor side than the first component 2010; wherein the first main body 200 is mechanically connected to the first component 2010, the first main body 200 and the pressure line 203 connected to the second main body 201 cooperate to clamp the glass 3, and the first main body 200 is closer to the outdoor side than the second main body 201; in the height direction of the second main body 201, a first card groove 20100 is provided on the side of the first component 2010 away from the glass 3, and the first card groove 20100 is lower than the first main body 200.

[0055] Taking door and window glass as an example, the top mentioned in this application is the side of the door and window glass facing away from the ground, and the bottom mentioned in this application is the side of the door and window glass close to the ground or the work platform.

[0056] The first body 200 and the second body 201 may both be profiles, and the material of the first body 200 and the material of the second body 201 may be the same or different;

[0057] When the first body 200 and the second body 201 are made of the same material, the first body 200 and the second body 201 are designed to be separate, which reduces the risk of defects on the components when molding larger components, improves the quality of the first body 200 and the second body 201 themselves, and thus improves the quality of the inward-tilted and sliding door and window movable glass sash 20 formed by the two.

[0058] The pressure line 203, also known as the glass 3 pressure line 203, is an indispensable component in the installation of the door and window glass 3. Its main function is to fix the glass 3 and ensure the stability and safety of the glass 3 in the window frame. It is generally set on the inner side of the glass 3. In addition, the glass sash pressure line 203 also plays a sealing role, preventing moisture and gas from penetrating from the gap between the glass 3 and the window frame, thereby enhancing the air tightness and water tightness of the doors and windows.

[0059] The indoor side mentioned in this application means the inner side of the building where the glass fan (or glass 3) is installed; the outdoor side mentioned in this application means the outer side of the building where the glass fan (or glass 3) is installed.

[0060] The first body 200 and the second body 201 can be connected by snapping together.

[0061] The first body 200 and the pressure line 203 connected to the second body 201 cooperate to clamp the glass 3. The first body 200 is closer to the outdoor side than the second body 201. The second body 201 includes a first component 2010 and a second component 2011. The second component 2011 is closer to the indoor side than the first component 2010. The first body 200 is mechanically connected to the first component 2010. The first component 2010 is provided with a first groove 20100 for installing the locking member 6 on the side away from the glass 3. The first groove 20100 is arranged to avoid the drainage cavity 102, so as to reduce the water condensed on the glass 3 and other liquids passing through the glass 3. The risk of the pressure line 203 or the connection of the first body 200 penetrating the door and window movable glass leaf 20 and contacting the locking member 6 is reduced. The first component 2010 is located between the first body 200 and the second body 201. The first body 200 and part of the first component 2010 can enclose a cavity (i.e., the drainage cavity 102 hereinafter) for collecting and discharging water and other liquids that penetrate into the door and window glass leaf frame. The position of the first card slot 20100 avoids the position of the drainage cavity, thereby reducing the risk of the locking member 6 rusting due to contact with water and other liquids, extending the service life of the locking member 6, and reducing the frequency of users replacing the locking member 6, thereby reducing the use cost of the door and window glass leaf;

[0062] The first card slot 20100 is located close to the indoor side, which reduces the impact of collisions, knocks and the like on the outdoor side on the doors and windows. The temperature of the area close to the indoor side where the first card slot 20100 is located can generally be maintained at a relatively mild state, with the temperature rarely being too high or too low, thereby reducing the risk of deformation of the locking member 6 due to thermal expansion and contraction, which causes squeezing of its own components and surrounding components, resulting in deformation of these components, and then causing the risk of deterioration or even damage to the coordination between the components of the locking member 6.

[0063] According to some embodiments of the present application, optionally, Figure 3 to Figure 7 As shown, the end of the second component 2011 away from the glass 3 is lower than the first groove 20100 , a first surface 2012 is formed between the first component 2010 and the second component 2011 , and the first surface 2012 is provided with a second groove 20120 protruding from the first surface 2012 .

[0064] The first surface 2012 can be in contact with the locking member 6, and the first surface 2012 can further limit the installation position of the locking member 6, or the first surface 2012 can be separated from the locking member 6 to provide a larger installation space for the locking member 6, thereby facilitating the installation or disassembly of the locking member 6.

[0065] The end of the second component 2011 facing away from the glass 3 is lower than the first slot 20100, so the second component 2011 can separate the first slot 20100 from the room, thereby protecting the locking member 6 disposed in the first slot 20100 from being easily affected by knocks or liquids from the room, thereby extending the service life of the locking member 6;

[0066] A first surface 2012 is formed between the first component 2010 and the second component 2011. The first surface 2012 is provided with a second slot 20120 protruding from the first surface 2012. The second slot 20120 can be used to install a seal that separates the installation space of the locking member 6 corresponding to the first slot 20100 from the indoor environment, thereby improving the sealing between the first surface 2012 and other components, thereby improving the effect of protecting the locking member 6 from the influence of the indoor environment.

[0067] According to some embodiments of the present application, optionally, Figure 5 and Figure 7 As shown, in the height direction of the second component 2011, the dimension of the first surface 2012 is h, which satisfies 15 mm ≤ h ≤ 30 mm.

[0068] When h is less than 15 mm, the installation space reserved for the locking member 6 is small. In order to match the size of the installation space, only a smaller locking member 6 can be installed. The smaller locking member 6 has a lower strength and is difficult to meet the use requirements of the door and window glass leaf, and is easily damaged.

[0069] When h>30mm, the installation space reserved for the locking member 6 is too large. On the one hand, under the premise that the size of the door and window glass panels is constant, less installation space is reserved for other components. On the other hand, the restriction effect on the shape and position of the locking member 6 is weak, and the locking member 6 is prone to deformation and damage.

[0070] In the height direction of the second component 2011, the size of the first surface 2012 is h, and the size of h is proportional to the size of the installation space reserved for the locking member 6 in the height direction of the second component 2011. When 15mm≤h≤30mm is satisfied, the size of the installation space reserved for the locking member 6 can meet the rated strength required for the use of door and window glass sashes.

[0071] According to some embodiments of the present application, optionally, Figure 3 to Figure 7 As shown, the first main body 200 includes a third component part 2000 and a fourth component part 2001; the third component part 2000 is closer to the outdoor side than the fourth component part 2001, the third component part 2000 has a second surface 20000 away from the glass 3, the fourth component part 2001 has a third surface 20010 away from the glass 3, and the third surface 20010 is not flush with the second surface 20000.
