Abstract
Description
Technical Field
[0001] This application relates to the field of door and window technology, and more specifically, to an anti-fall hanging structure and a top-hung window. Background Technology
[0002] In the process of building decoration, top-hung windows are becoming more and more widely used. Top-hung windows are generally made by rotating the window sash to the window frame and then setting a limit screw to limit the rotation and opening of the top-hung window.
[0003] However, in practical applications, the limit screws can easily come loose due to the opening and closing of top-hung windows or the effects of external wind and rain. In addition, when using limit screws for restraint, installers may forget to install them during the installation of top-hung windows. Whether the limit screws come loose or are forgotten to be installed, the window sash will lose its restraint, making it extremely easy for it to fall.
[0004] To address the aforementioned problems, this application proposes a new solution. Summary of the Invention
[0005] The purpose of this application is to provide a fall-prevention hanging structure and a top-hung window, which have the advantages of safety and stability.
[0006] Firstly, this application provides a fall-prevention mounting structure, the technical solution of which is as follows:
[0007] The window frame includes a window frame and a window sash. The window frame is positioned above the window sash and has a first contact portion that is rotatably connected to the window sash. The window frame also includes:
[0008] The second contact portion is provided with a contact surface, and the first contact portion is provided with a raised first arc surface. The contact surface and the raised side of the first arc surface face each other in the horizontal direction and are spaced apart.
[0009] The window sash includes a window body and a connecting part connected to the window body. The connecting part is disposed between the abutting surface and the first arc surface. The connecting part is provided with an inwardly recessed third arc surface. The third arc surface is movably engaged with the first arc surface. The abutting surface is used to contact and limit the connection part.
[0010] The window frame has a first contact portion with a raised first arc surface. The connecting portion of the window sash has an inwardly recessed third arc surface. The movable fit between the third arc surface and the first arc surface allows the connecting portion to rotate relative to the first contact portion. In addition, the window frame also has a second contact portion with an abutting surface. The abutting surface and the raised side of the first arc surface face each other and are spaced apart. The connecting portion is located between the first arc surface and the abutting surface. When the third arc surface rotates relative to the first arc surface, because the abutting surface and the first arc surface face each other and are spaced apart, if the connecting portion tends to detach from the first contact portion, it will contact and be stopped by the abutting surface, thus preventing the window sash from falling. Since the second contact part is directly installed on the window frame and does not need to be disassembled, it also avoids the situation of forgetting to install it. In addition, the abutting surface and the raised side of the first arc surface are arranged horizontally and are spaced apart. When the window connecting part rotates relative to the first arc surface of the first contact part through the third arc surface, the traction force on the connecting part caused by the gravity of the window can be decomposed into a horizontal force and a vertical force. Since the abutting surface and the raised side of the first arc surface are arranged horizontally and are spaced apart, the decomposed horizontal force will act on the first arc surface or the abutting surface, thereby forming a horizontal support for the connecting part to ensure the stability of the window sash as a whole during the operation. Therefore, the anti-fall hanging structure and top-hung window proposed in this application have the beneficial effect of safety and stability.
[0011] Furthermore, in this application, the contact surface is a raised second arc surface, one side of the raised second arc surface and one side of the raised first arc surface are horizontally oriented towards each other and spaced apart, and the connecting part is provided with a fourth arc surface that is concentric with the third arc surface and protrudes outward, and the second arc surface is used to contact and limit the fourth arc surface.
[0012] The above settings allow for a larger opening and closing angle in the connecting part.
[0013] Furthermore, in this application, the window frame has a cavity, the cavity has an opening communicating with the outside, the opening is located below or diagonally below the cavity, and the first contact portion and the second contact portion are located inside the cavity.
[0014] The above-mentioned design can prevent dust and water damage, and ensure the stability of the connection between the connecting part and the first contact part.
[0015] Furthermore, in this application, the cavity is surrounded by a vertically arranged first sidewall, a second sidewall, and a third sidewall connecting the top of the first sidewall and the top of the second sidewall, with the first contact portion disposed on the first sidewall and the second contact portion disposed on the second sidewall.
[0016] Furthermore, in this application, an extension section is provided between the first contact portion and the first sidewall. One end of the extension section is connected to the first sidewall, and the other end is connected to the first arc surface. Based on the extension section, a groove is formed between the first arc surface and the first sidewall.
[0017] Furthermore, in this application, a connecting rod extends from one end of the connecting part, the connecting rod is connected to the window, the connecting rod is inclined toward the side of the second contact part, the window is set outside the window frame, one end of the connecting rod is connected to the connecting part, and the other end passes through the opening and is connected to the window.
[0018] Furthermore, in this application, the second contact portion includes a rotatably disposed engagement portion, the second arc surface is disposed on the protruding side of the engagement portion, the engagement portion is further provided with a fifth arc surface that is concave inward and concentric with the second arc surface, and the second contact portion is further provided with a sixth arc surface that is movably engaged with the fifth arc surface.
[0019] Furthermore, in this application, the second arc surface is provided with a first convex tooth, and the fourth arc surface is provided with a second convex tooth that meshes with the first convex tooth.
[0020] Furthermore, in this application, the first protruding tooth is provided in multiple forms, and the third arc surface is an open arc.
[0021] Secondly, this application also provides a top-hung window, which includes the aforementioned anti-fall hanging structure.
[0022] As can be seen from the above, the anti-fall hanging structure and top-hung window provided in this application have a first contact portion in the window frame, the first contact portion having a raised first arc surface, and a connecting portion of the window sash having an inwardly recessed third arc surface. The movable cooperation between the third arc surface and the first arc surface allows the connecting portion to rotate relative to the first contact portion. In addition, the window frame also has a second contact portion, the second contact portion having an abutting surface, and the abutting surface and the raised side of the first arc surface are facing each other and spaced apart. The connecting portion is located between the first arc surface and the abutting surface. When the third arc surface and the first arc surface rotate relative to each other, since the abutting surface and the first arc surface are facing each other and spaced apart, when the connecting portion rotates relative to the first arc surface of the first contact portion through the third arc surface, if the connecting portion tends to detach from the first contact portion, it will come into contact with the abutting surface. The first contact part is directly mounted on the window frame and does not need to be disassembled, thus avoiding the possibility of forgetting to install it. In addition, the contact surface and the raised side of the first arc surface face each other horizontally and are spaced apart. When the window body connecting part rotates relative to the first arc surface of the first contact part through the third arc surface, the traction force on the connecting part caused by the weight of the window body can be decomposed into a horizontal force and a vertical force. Since the contact surface and the raised side of the first arc surface face each other horizontally and are spaced apart, the decomposed horizontal force will act on the first arc surface or the contact surface, thereby providing horizontal support for the connecting part to ensure the stability of the window sash as a whole during operation. Therefore, the anti-fall hanging structure and top-hung window proposed in this application have the beneficial effects of safety and stability. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] The structure of a top-hung window is generally as follows: Figure 1 As shown, it includes at least a window frame 001 mounted on a windowsill and a window sash 002 rotatably mounted on the window frame 001. Generally, the rotatable connection between the window sash 002 and the window frame 001 can be achieved by means of hinges, etc. However, in actual applications, the window frame 001 is in a narrow space. In order to facilitate the installation of the window and based on the overall structure of the window, the actual window frame 001 is provided with an upward protrusion 003, and the window sash 002 is provided with a barb 004. The barb 004 hangs upside down on the protrusion 003, thereby realizing the rotatable connection between the window sash 002 and the window frame 001. This rotatable connection method is easy to install and disassemble. Therefore, most top-hung windows currently use this connection structure.
[0033] However, if the window sash 002 is not properly limited by this connection structure, the hook 004 will easily detach from the boss 003 during rotation because the window sash 002 flips upwards during use.
[0034] In this regard, the existing technology generally involves first hanging the barb 004 upside down on the boss 003, and then setting a limiting screw 005 above the barb 004 to limit the barb 004 and prevent the barb 004 from detaching from the boss 003 during the flipping process.
[0035] However, in actual use, the window sash 002 is usually flipped upwards. During the flipping process, it may come into contact with the limit screw 005. Under the action of external forces such as wind and rain, the limit screw 005 will gradually loosen and fall off. When the limit screw 005 falls off, the window sash 002 will be very likely to fall off during rotation.
[0036] In addition, since the limit screw 005 can only be installed after the barb 004 is hung upside down on the boss 003, it is easy to forget to install the limit screw 005, which will make the window sash 002 very easy to fall off during rotation.
[0037] For this, please refer to Figures 2 to 6 This application proposes a fall-prevention mounting structure, the technical solution of which is as follows:
[0038] The window frame 001 and window sash 002 are included. The window frame 001 is located above the window sash 002. The window frame 001 is provided with a first contact part 100 that is rotatably connected to the window sash 002. The window frame 001 also includes:
[0039] The second contact portion 200 is provided with a contact surface 210, and the first contact portion 100 is provided with a raised first arc surface 110. The raised side of the first arc surface 110 and the contact surface 210 face each other and are spaced apart. A gap is formed between the raised side of the first arc surface 110 and the contact surface 210 due to the spaced arrangement.
[0040] The second contact part 200 can be integrally formed with the window frame 001, which avoids the need to install the second contact part 200 and thus avoids the situation of forgetting to install it.
[0041] The window sash 002 includes a window body 300 and a connecting part 400 connected to the window body 300. The connecting part 400 is disposed in the gap between the protruding side of the first arc surface 110 and the contact surface 210. The connecting part 400 is provided with an inwardly recessed third arc surface 410, which is in movably engaged with the first arc surface 110.
[0042] In order to facilitate installation, the third arc surface 410 of the connecting part 400 is an open arc, specifically a semi-circular arc. In some embodiments, the connecting part 400 can be a hook-shaped structure.
[0043] The relative rotation between the connecting part 400 and the first contact part 100 is achieved through the sliding engagement of the inwardly recessed third arc surface 410 and the protruding first arc surface 110. Since the connecting part 400 is positioned in the gap between the protruding side of the first arc surface 110 and the abutment surface 210, the abutment surface 210 contacts the connecting part 400 to limit its movement. Because a gap is formed between the protruding side of the first arc surface 110 and the abutment surface 210, and the third arc surface 410 is an open arc, the connecting part 400 can be quickly and easily installed within the gap. Rotation is achieved through the movable engagement of the third arc surface 410 and the first arc surface 110. During rotation, if the connecting part 400 tends to detach from the first contact part 100, it will contact the abutment surface 210, which limits its movement and prevents it from falling.
[0044] The contact surface 210 and the first arc surface 110 can be arranged to face each other vertically and at intervals, can be arranged to face each other at intervals in an inclined direction, or can be arranged to face each other at intervals in a horizontal direction.
[0045] In some preferred embodiments, the contact surface 210 and the first arc surface 110 face each other horizontally and are spaced apart.
[0046] This is because the window sash 002 is usually located below the window frame 001. When the window sash 002 needs to be opened, it rotates counterclockwise from a vertical position to a tilted position. When the window sash 002 is tilted, the force under its gravity can be decomposed into horizontal and vertical forces. If the contact surface 210 and the first arc surface 110 are vertically aligned and spaced apart, the horizontal force will be difficult to support, making it more prone to detachment. The contact surface 210 and the raised side of the first arc surface 110 are horizontally oriented towards each other and spaced apart. Since the connecting part 400 is located between the contact surface 210 and the raised side of the first arc surface 110, when the window sash 002 is in the open state, the force decomposed into the horizontal direction can directly act on the contact surface 210 or the first arc surface 110 and be supported by the first contact part 100 or the second contact part 200. Therefore, the window sash 002 can be more stable during rotation, effectively preventing it from falling off and providing a safer effect.
[0047] Similarly, if the contact surface 210 and the first arc surface 110 are inclined towards each other and spaced apart, the contact surface 210 or the first arc surface 110 cannot fully withstand the force that is decomposed into the horizontal direction, so its safety and stability are still insufficient.
[0048] Therefore, in a preferred embodiment, the contact surface 210 and the first arc surface 110 face each other horizontally and are spaced apart, which has a safer and more stable effect.
[0049] The contact surface 210 is a surface used to limit the connection part 400. The contact surface 210 can maintain continuous contact with the connection part 400, or it can leave a gap between the contact surface 210 and the connection part 400. When the connection part 400 is rotating and comes into contact with the contact surface 210 again, the contact surface 210 can be used to limit the connection part 400. Since the contact surface 210 is mainly used to limit the connection part 400, it can be a plane or a curved surface, and it can be an inwardly concave curved surface or an outwardly convex curved surface.
[0050] While ensuring high safety and stability during the opening and closing of window sash 002, improving the opening angle of window sash 002 has become a challenge. Generally speaking, the larger the opening angle of window sash 002, the better the view obtained when opening window sash 002. Therefore, top-hung windows with large opening angles are a major demand direction in the current market. However, due to limited space, window structure and other factors, especially when using a hanging structure, the opening angle of window sash 002 is relatively small. This is because a limiting structure is needed to limit the rotation of window sash 002 to prevent it from falling off. However, the limiting structure itself will interfere with the rotation of window sash 002, making it difficult to achieve a large opening angle.
[0051] In this application, the limiting structure is the abutment surface 210 of the second contact portion 200. The abutment surface 210 is used to contact and limit the connection portion 400, thereby preventing the connection portion 400 from disengaging from the first arc surface 110 during rotation. While limiting the connection portion 400, the abutment surface 210 also affects the opening angle of the window sash 002. In particular, in order to ensure the safety and stability of the window sash 002 during the opening and closing process, the abutment surface 210 and the protruding side of the first arc surface 110 are set to face each other in the horizontal direction, which further affects the opening angle of the window sash 002.
[0052] Since the influence on the opening angle of the window sash 002 is mainly caused by the contact surface 210, this application will further improve the contact surface 210 to increase the opening angle of the window sash 002.
[0053] In this application, the contact surface 210 is configured as a curved surface that protrudes toward the first arc surface 110, that is, a protruding second arc surface. The connecting part 400 is provided with a fourth arc surface 420 that is concentric with the third arc surface 410 and protrudes outward. The second arc surface is used to contact and limit the fourth arc surface 420.
[0054] When the third arc surface 410 rotates relative to the first arc surface 110, the fourth arc surface 420 will also rotate concentrically. Since the second arc surface and the first arc surface 110 face each other and are spaced apart, the second arc surface is located on the side closer to the fourth arc surface 420 and is used to contact the fourth arc surface 420. When the connecting part 400 rotates relative to the first arc surface 110 of the first contact part 100 through the third arc surface 410, if the connecting part 400 tends to detach from the first contact part 100, the fourth arc surface 420 will be limited by the contact of the second arc surface, thereby preventing the window sash 002 from falling.
[0055] In this process, the contact surface 210 is configured as a second arc surface that protrudes towards the first arc surface 110, and the side of the connecting part 400 near the second arc surface is configured as a fourth arc surface 420 concentric with the third arc surface 410. The fourth arc surface 420 rotates concentrically with the third arc surface 410, which can reduce the interference between the connecting part 400 and the second contact part 200. Specifically, when the connecting part 400 disengages from the first arc surface 110 during rotation, since the side of the connecting part 400 near the second contact part 200 is the fourth arc surface 420 that protrudes outward and is concentric with the third arc surface 410, there will be no extra interference between the fourth arc surface 420 and the second contact part 200 during rotation. The second contact portion 200 has a raised second arc surface on the side near the connecting portion 400. That is, the closer the second arc surface is to the connecting portion 400, the more its surface tapers inward. Since the window sash 002 needs to rotate and swing during the opening and closing process, the closer the second arc surface is to the rotation center of the connecting portion 400, the more its surface tapers inward, which can reduce interference with the connecting portion 400 and thus reduce the impact on the opening and closing angle of the connecting portion 400.
[0056] Furthermore, referring to Figure 4 In some embodiments, the window frame 001 has a cavity 120, the cavity 120 has an opening 160 communicating with the outside, the opening 160 is located below or diagonally below the cavity 120, and the first contact portion 100 and the second contact portion 200 are located inside the cavity 120.
[0057] Specifically, the cavity 120 is surrounded by a vertically arranged first sidewall 130, a second sidewall 150, and a third sidewall 140 connecting the top of the first sidewall 130 and the top of the second sidewall 150. A first contact portion 100 is disposed on the first sidewall 130, and a second contact portion 200 is disposed on the second sidewall 150.
[0058] By setting up a cavity 120 and placing the first contact part 100 and the second contact part 200 inside the cavity 120, dust and water can be prevented, thereby ensuring the connection stability between the window sash 002 and the first contact part 100 and improving the service life.
[0059] Furthermore, since the cavity 120 is formed by being surrounded by the first sidewall 130, the second sidewall 150, and the third sidewall 140, and the first contact portion 100 is disposed on the first sidewall 130, the second contact portion 200 is disposed on the second sidewall 150, and the first arc surface 110 protruding on the first contact portion 100 and the abutting surface 210 on the second contact portion 200 are horizontally oriented towards each other and spaced apart, the distance between the first sidewall 130 and the second sidewall 150 can be made farther apart, which is more beneficial to the overall stress stability of the window frame 001 compared with the prior art.
[0060] Generally, hinges or pivots are used to achieve a rotatable connection between two components. However, in top-hung windows, due to the limited space of the window frame 001, a hook-and-loop connection is used between the window sash 002 and the window frame 001 for ease of installation and based on the window's structural design. Specifically, in this application, the first contact portion 100 has a raised first arc surface 110, and the connecting portion 400 has a third arc surface 410. The third arc surface 410 is an open arc, allowing the connecting portion 400 to be hung upside down on the first contact portion 100. The connection is achieved through the third arc surface 410 and the first arc surface 110. The rotation of the connecting part 400 and the first contact part 100 is achieved through the movement of the 0. In this case, in addition to the contact of the abutting surface 210 with the connecting part 400 affecting the opening and closing angle, the cooperation between the third arc surface 410 and the first arc surface 110 also affects the opening and closing angle. This is because the third arc surface 410 is an open arc and hangs on the first arc surface 110 in an inverted manner. Therefore, the contact position between the connecting part 400 and the first contact part 100 is usually a hook-shaped structure, and the contact position of its end with the connection between the first contact part 100 and the first side wall 130 will affect the opening and closing angle of the connecting part 400.
[0061] To address this, the connection position between the first contact portion 100 and the first sidewall 130 can be further improved so that the connection portion 400 has a larger opening and closing angle.
[0062] Specifically, an extension 170 is provided between the first contact portion 100 and the first sidewall 130. One end of the extension 170 is connected to the first sidewall 130, and the other end is connected to the first arc surface 110. Based on the extension 170, a groove 180 is formed between the first arc surface 110 and the first sidewall 130.
[0063] Specifically, the method of forming a groove 180 between the first arc surface 110 and the first sidewall 130 based on the extension 170 can be to make the thickness of the extension 170 smaller than the diameter of the first arc surface 110. Specifically, the first arc surface 110 can be a sphere or a cylinder.
[0064] If the first contact portion 100 is directly disposed on the first side wall 130, the first side wall 130 will be directly connected to the first arc surface 110. The connecting portion 400 will be in active cooperation with the first arc surface 110 through the third arc surface 410. This will cause the end of the connecting portion 400 to easily contact and interfere with the first side wall 130, thereby affecting the opening and closing angle of the connecting portion 400.
[0065] In this application, an extension 170 is provided between the first sidewall 130 and the first arc surface 110, and the thickness of the extension 170 is less than the diameter of the first arc surface 110. This allows a groove 180 to be formed between the first arc surface 110 and the first sidewall 130. During the process of the connecting part 400 moving and engaging with the first arc surface 110 of the first contact part 100 through the third arc surface 410, the groove 180 can accommodate the end of the connecting part 400, thereby increasing its opening and closing angle.
[0066] When the window sash 002 is closed, it is in a vertical position. At this time, the connecting part 400 applies a downward vertical force to the window frame 001. Since the connecting part 400 is in contact with the first arc surface 110 of the first contact part 100 through the third arc surface 410, the force mainly acts on the first contact part 100. In some of the above embodiments, an extension section 170 is provided between the first contact part 100 and the first side wall 130. Even if the window sash 002 is supported by other structures, the first contact part 100 or the extension section 170 may still be damaged by long-term stress.
[0067] In this regard, refer to Figure 5 Furthermore, this application provides a connecting rod 500 extending from one end of the connecting part 400. The connecting rod 500 is connected to the window 300. The connecting rod 500 is inclined toward the second contact part 200. The window 300 is located outside the window frame 001. One end of the connecting rod 500 is connected to the connecting part 400, and the other end passes through the opening 160 and is connected to the window 300.
[0068] The window 300 and the connecting part 400 are connected by an inclined connecting rod 500, which converts the originally vertically downward gravity into a tensile force along the inclined direction of the connecting rod 500. Since the tensile force is inclined towards the second contact part 200, it can be decomposed into a horizontal force pointing towards the second contact part 200 and a vertical force. Since the connecting part 400 is located between the first arc surface 110 and the abutment surface 210, and the first arc surface 110 and the abutment surface 210 are horizontally oriented towards each other and spaced apart, the force decomposed into a horizontal force pointing towards the second contact part 200 will cause the connecting part 400 to contact the abutment surface 210, which will be borne and supported by the second contact part 200. Through force decomposition, the force exerted by the window sash 002 on the first contact part 100 is reduced, thereby improving the service life of the first contact part 100 and the extension 170.
[0069] Furthermore, in some embodiments, the second contact portion 200 includes a rotatably disposed engagement portion 220, a second arcuate surface is disposed on the protruding side of the engagement portion 220, the engagement portion 220 is also provided with a fifth arcuate surface 230 that is concave inward and concentric with the second arcuate surface, and the second contact portion 200 is also provided with a sixth arcuate surface 250 that is movably engaged with the fifth arcuate surface 230.
[0070] If the connecting part 400 tends to disengage from the first contact part 100 during the opening and closing process, the fourth arc surface 420 will contact the engaging part 220 provided on the second contact part 200. The second arc surface on the engaging part 220 will contact and limit the fourth arc surface 420. The engaging part 220 is rotatably provided. When the second arc surface is contacted by the fourth arc surface 420, the engaging part 220 can rotate, which can change the original sliding friction into rolling friction. Therefore, the friction force can be reduced, making the connecting part 400 safer and more stable during the opening and closing process, and extending its service life.
[0071] Furthermore, in some embodiments, a first protruding tooth 240 is provided on the second arc surface, and a second protruding tooth 430 that meshes with the first protruding tooth 240 is provided on the fourth arc surface 420.
[0072] Specifically, there are multiple first protruding teeth 240, which are distributed along the arc direction of the sixth arc. There are multiple second protruding teeth 430, which are distributed along the arc direction of the fourth arc surface 420.
[0073] By engaging the first tooth 240 and the second tooth 430, the force can be transmitted more smoothly, making the connecting part 400 safer and more stable during opening and closing rotation.
[0074] Secondly, this application also provides a top-hung window, which includes the aforementioned anti-fall hanging structure.
[0075] Applying the aforementioned anti-fall hanging structure to top-hung windows makes them safer and more stable.
[0076] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
