Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a narrow-sided inward-opening window with an L-shaped load-bearing structure. Background Technology

[0002] A window consists of a window frame structure and a window sash structure. The window sash structure with operable glass generally also includes an inner frame, an outer frame, and a thermal insulation strip. The thermal insulation strip overlaps between the inner and outer frames. The inner and outer frames are used to support the operable glass. When the operable glass is closed, the thermal insulation strip is used for sealing and buffering between the window sash structure and the window frame structure.

[0003] In the existing technology, both the inner and outer frames are made of cavity aluminum profiles to ensure the stability of the inner and outer frames in supporting the operable glass. However, the use of cavity aluminum profiles for both the inner and outer frames results in a large space occupied by the inner and outer frames, and the heat insulation strips overlapping between the inner and outer frames are relatively narrow, leading to poor heat insulation performance.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] In this utility model, a narrow-sided inward-opening window with an L-shaped load-bearing structure includes a window frame structure and a window sash structure. The window sash structure rotates relative to the window frame structure and opens towards the interior.

[0009] The window sash structure includes an inner frame, an operable sash glass, a thermal insulation strip, an outer frame, and an L-shaped load-bearing structure. The thermal insulation strip overlaps between the inner frame and the outer frame and is fixed relative to each other. The operable sash glass is located in the support groove formed by the inner frame, the thermal insulation strip, and the outer frame. It is supported by the L-shaped load-bearing structure combined with the inner frame and fixed to the corresponding inner and outer frames by structural adhesive.

[0010] The inner frame is a cavity aluminum profile, and the outer frame is a narrow-edge aluminum plate.

[0011] Furthermore, the side of the L-shaped support structure away from the operable sash glass contacts the inner frame and forms a gap with the heat insulation strip.

[0012] Furthermore, a load-bearing groove is provided on the inner frame, and the load-bearing groove is connected to the support groove;

[0013] The load-bearing groove includes a groove one and a groove two, and groove one and groove two are connected. The depth of groove one is L, and the depth of groove two is L.

[0014] The L-shaped support structure is a load-bearing block made of stainless steel, L-shaped, and connected to the inner frame through a load-bearing groove.

[0015] The length of the load-bearing block located inside the groove along the groove depth direction is L0, and L2 < L0 < L1.

[0016] Furthermore, the operable window glass is located above the load-bearing block, and a buffer block is provided between the operable window glass and the load-bearing block;

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] This application provides a narrow-sided inward-opening window with an L-shaped load-bearing structure, which solves the problem of large space occupied by the inner and outer frames in the prior art and improves the heat insulation effect.

[0036] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0037] In the existing technology, both the inner frame and the outer frame are set as cavity aluminum profiles to ensure the stability of the inner frame and the outer frame in supporting the operable glass. However, the use of cavity aluminum profiles for both the inner frame and the outer frame results in a large space occupied by the inner and outer frames, and the heat insulation strip overlapping between the inner and outer frames is relatively narrow, resulting in poor heat insulation effect.

[0038] Research has found that, for example Figures 1-4 As shown, by setting up an L-shaped load-bearing structure, the operable glass is supported. During the support process, the L-shaped load-bearing structure hooks onto the inner frame and has strong structural force, which can easily support glass weighing over 1 kg, thereby enhancing the load-bearing capacity of the window sash structure. Larger operable glass can be made, and the stable structure of the L-shaped load-bearing structure also extends the service life of the product.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Example:

[0041] like Figures 1-2 As shown, a narrow-sided inward-opening window with an L-shaped load-bearing structure includes a window frame structure 1 and a window sash structure 2, wherein the window sash structure 2 rotates relative to the window frame structure 1 and opens toward the interior.

[0042] The window sash structure 2 includes an inner frame 20, an operable sash glass 21, a thermal insulation strip 24, an outer frame 26, and an L-shaped load-bearing structure. The thermal insulation strip 24 overlaps between the inner frame 20 and the outer frame 26 and is fixed relative to each other. The operable sash glass 21 is located in the support groove formed by the inner frame 20, the thermal insulation strip 24, and the outer frame 26. It is supported by the L-shaped load-bearing structure combined with the inner frame 20 and fixed to the corresponding inner frame 20 and outer frame 26 by structural adhesive.

[0043] The inner frame 20 is a cavity aluminum profile, and the outer frame 26 is a narrow-edge aluminum plate.

[0044] By setting up an L-shaped load-bearing structure, the L-shaped load-bearing structure supports the operable glass 21. During the support process, the L-shaped load-bearing structure hooks onto the inner frame 20 and has strong structural force, which can easily support glass weighing more than 150 kg, thereby enhancing the load-bearing capacity of the window sash structure 2. Larger operable glass 21 can be made, and the service life of the product is also extended due to the structural stability of the L-shaped load-bearing structure.

[0045] Meanwhile, by utilizing the L-shaped load-bearing structure for support, compared to the existing technology where both the inner and outer frames 26 need to be made of cavity aluminum profiles to support the window glass, the improved window sash structure 2 can support the window glass using the load-bearing structure of the L-shaped load-bearing structure. Therefore, the outer frame 26 does not need to use cavity aluminum profiles; only narrow-edge aluminum profiles are needed. Through the above settings, within the same design space, the thermal insulation strip 24 between the inner frame 20 and the outer frame 26 is wider than the thermal insulation strip 24 in the existing technology, achieving a better thermal insulation effect. This solves the problem of the inner and outer frames 26 occupying a large space in the existing technology, thereby improving the thermal insulation effect.

[0046] like Figure 2 As shown, the side of the L-shaped support structure away from the opening sash glass 21 contacts the inner frame 20 and forms a gap 241 between it and the heat insulation strip 24.

[0047] The L-shaped support structure is supported by the inner frame 20. A gap 241 is formed between the L-shaped support structure and the heat insulation strip 24, which avoids the weight of the glass on the operable window 21 acting on the heat insulation strip 24. This effectively prevents the L-shaped support structure from squeezing the heat insulation strip 24 when supporting the operable window 21, thus preventing the heat insulation effect from being reduced.

[0048] like Figures 2-3 As shown, a load-bearing groove 22 is provided on the inner frame 20, and the load-bearing groove 22 is connected to the lifting groove;

[0049] The load-bearing groove 22 includes a groove one and a groove two, and the groove one and the groove two are connected. The depth of the groove one is L1, and the depth of the groove two is L2.

[0050] The L-shaped support structure is a load-bearing block 23. The load-bearing block 23 is made of 304 stainless steel, is L-shaped, and is connected to the inner frame 20 through the load-bearing groove 22.

[0051] The length of the load-bearing block 23 located inside the groove along the groove depth direction is L0, and L2 < L0 < L1.

[0052] By defining the load-bearing groove 22 and setting it to be a combination of groove one and groove two, the load-bearing block 23 after connection is limited by groove two, thereby improving the stability of the connection between the load-bearing block 23 and the inner frame 20, and thus facilitating the stability of the load-bearing block 23 in supporting the opening window glass 21.

[0053] like Figure 2 As shown, the operable window glass 21 is located above the load-bearing block 23, and a buffer block 231 is provided between the operable window glass 21 and the load-bearing block 23.

[0054] The buffer block 231 is fixed to the corresponding load-bearing block 23 and the opening window glass 21 on both the top and bottom surfaces.

[0055] Specifically, structural adhesive can be used to fix the upper and lower surfaces of the buffer block 231 to the corresponding load-bearing block 23 and the operable window glass 21.

[0056] By setting the buffer block 231, it is possible to facilitate the buffering during the assembly of the opening window 21, and the structural adhesive is used to achieve the stability of the installation of the opening window 21 and the load-bearing block 23.

[0057] like Figure 2 As shown, an adhesive strip 251 is installed on the inner frame 20;

[0058] The second adhesive strip 251 is bonded to the operable sash glass 21 and embedded in the inner frame 20 through the adhesive groove 25.

[0059] By opening a groove 25 on the inner frame 20, the second adhesive strip 251 is initially fixed, which facilitates the subsequent fixation of the second adhesive strip 251 with glue.

[0060] like Figure 1 and Figure 4 As shown, a fixed sash 10 is also installed on the window frame structure 1. The fixed sash 10 is located below the operable sash glass 21. A rubber strip 11 is installed between the fixed sash 10 and the window frame structure 1.

[0061] The adhesive strip 11 is composed of a rigid adhesive strip and a soft adhesive strip. The side of the adhesive strip 11 that contacts the window frame structure 1 is a rigid adhesive strip, and the side that contacts the fixed sash 10 is a soft adhesive strip in the shape of a rubber brush 113.

[0062] A pad 112 is also provided on the adhesive strip 11. The pad 112 is integrally formed with the adhesive strip 11 and is made of rigid adhesive strip. It is used to buffer the fixing of the sash 10 and the window frame structure 1.

[0063] By setting the rubber strip 11 to a combination of hard and soft rubber, the stability of the rubber strip 11 buffer can be improved while fixing the fan 10 for cushioning.

[0064] like Figure 4 As shown, the hard rubber of the rubber strip 11 has a deformation hole 111, which is elliptical in shape.

[0065] By creating deformation holes 111 in the hard rubber of the rubber strip 11, the deformation holes 111 facilitate the tightness of the connection between the rubber strip 11 and the fixed sash 10 and the window frame structure 1, thereby enhancing the sealing degree of the fixed sash 10.

[0066] During operation, first, install the heat insulation strip 24 between the inner frame 20 and the outer frame 26;

[0067] Next, the L-shaped support structure is inserted into the slot one through the slot two, so that the load-bearing slot 22 limits the L-shaped support structure.

[0068] Then, the operable sash glass 21 is fixed between the corresponding inner frame 20 and outer frame 26 using structural adhesive, and a buffer block 231 is set between the L-shaped support structure and the operable sash glass 21 to buffer the contact surface between the operable sash glass 21 and the L-shaped load-bearing structure. The contact surfaces of the buffer block 231 with the L-shaped load-bearing structure and the operable sash glass 21 are all fixed by adhesive.

[0069] Finally, adhesive strip 251 is used to cover the gap between the inner frame 20 and the operable window glass 21, thereby improving the aesthetics between the visible surface of the inner frame 20 and the operable window glass 21.

[0070] Similarly, the installation of the adhesive strip 11 with the fixed sash 10 and the window frame structure 1 is completed by means of adhesive application.

[0071] In summary, compared with existing technologies, it has the following beneficial effects:

[0072] 1. By setting up an L-shaped load-bearing structure, the operable glass 21 is supported. During the support process, the L-shaped load-bearing structure hooks onto the inner frame 20 and has strong structural force, which can easily support glass weighing more than 150 kg, thereby enhancing the load-bearing capacity of the window sash structure 2. Larger operable glass 21 can be made. Moreover, due to the structural stability of the L-shaped load-bearing structure, the service life of the product is also extended.

[0073] 2. Simultaneously, by utilizing the L-shaped load-bearing structure for support, compared to the existing technology where both the inner and outer frames 26 need to be cavity-type aluminum profiles to support the window glass, the improved window sash structure 2 can support the window glass using the L-shaped load-bearing structure. Therefore, the outer frame 26 does not need to use cavity-type aluminum profiles; only narrow-edge aluminum profiles are required. Through the above arrangement, within the same design space, the thermal insulation strip 24 between the inner frame 20 and the outer frame 26 is wider than the thermal insulation strip 24 in the existing technology, achieving a better thermal insulation effect. This solves the problem of the inner and outer frames 26 occupying a large space in the existing technology, thereby improving the thermal insulation effect.

[0074] 3. The L-shaped support structure is supported by the inner frame 20. A gap 241 is formed between the L-shaped support structure and the heat insulation strip 24, which avoids the weight of the glass on the operable window 21 from acting on the heat insulation strip 24. This effectively prevents the L-shaped support structure from squeezing the heat insulation strip 24 when supporting the operable window 21, thus preventing the heat insulation effect from being reduced.
