Description

Technical Field

[0001] This disclosure generally relates to the field of side-pressure window technology, and specifically to a thermally insulated side-pressure window. Background Technology

[0002] Thermally broken aluminum side-pressure windows are one of the mainstream products in the current architectural window and door industry. Their core structure employs a thermal break design, effectively blocking heat conduction paths between metal profiles by embedding thermal break strips. This retains the high strength and deformation resistance of the metal profiles, meeting the structural stability requirements of building windows and doors, while reducing indoor-outdoor heat exchange efficiency, thus providing basic energy-saving and thermal insulation performance. Furthermore, the side-pressure opening mechanism of this window type is easy to operate, does not occupy additional outdoor or indoor space during opening, and is suitable for the facade design and usage needs of various building scenarios such as single-level apartments, villas, and office buildings, making it widely used in various construction projects.

[0003] The locking of side-pressure windows usually requires the cooperation of a transmission rod. The transmission rods of existing side-pressure windows are all inside the aluminum alloy groove. Since the transmission rods are generally made of aluminum alloy, this directly causes a thermal bridge to be formed between the inside and outside of the window sash, resulting in the loss of the window's thermal insulation performance.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Please refer to Figures 1-8 This application provides a thermally insulated side-pressure window, including an outer frame 100, a mullion 200, a fixed sash 300, and a movable sash 400. The mullion 200 and the outer frame 100 enclose a first space and a second space. The fixed sash 300 is disposed in the first space. The movable sash 400 is slidably disposed on the outer frame 100 and cooperates with the mullion 200 and the outer frame 100. The movable sash 400 includes: A first profile 410 and a second profile 420 are connected by a first heat insulation strip 430 and a second heat insulation strip 440, and the second heat insulation strip 440 is provided with a guide groove 441. A transmission rod 450 is slidably installed in the guide groove 441 and connected to a handle 401 provided on the movable fan 400; A locking mechanism is connected to the transmission rod 450 and is used to lock the fixed fan 300. A folding screen assembly, which is movably installed within the second space.

[0020] Specifically, the outer frame 100 is made of high-strength aluminum alloy, providing a stable installation foundation and structural support for the entire side-pressure window. The mullion 200 is fixed inside the outer frame 100 with bolts, forming two independent spaces together with the inner wall of the outer frame 100: a first space for installing the fixed sash 300 and a second space for accommodating the folding screen assembly. The fixed sash 300, including the second glass 700, is fixed in the first space by a sealing strip and features a double-layer hollow structure to further enhance the overall insulation effect. The movable sash 400 has its two sides slidably mounted on the track of the outer frame 100 via a pulley assembly, allowing it to slide along the track. One side of the movable sash 400 fits against the side of the mullion 200, and the other side adapts to the inner wall of the outer frame 100, achieving a sealed fit when closed.

[0021] A first glass 600 is installed between the first profile 410 and the second profile 420 of the movable fan 400. Both the first profile 410 and the second profile 420 are special profiles for thermally broken aluminum alloys. They are arranged in parallel and spaced apart, and connected by two parallel first thermal insulation strips 430 and second thermal insulation strips 440, which can effectively block heat conduction between the profiles. A guide groove 441 extending along the length of the thermal insulation strip is integrally formed inside the second thermal insulation strip 440. The cross-section of the guide groove 441 is U-shaped, providing a sliding channel for the transmission rod 450. The transmission rod 450 is a long strip of metal rod, which is integrally fitted and installed in the guide groove 441. It can slide smoothly along the length of the guide groove 441. At the same time, the middle part of the transmission rod 450 is connected to the handle 401 on the outer wall of the movable fan 400. When the handle 401 is turned, the transmission rod 450 can be directly driven to move synchronously. The locking mechanism is installed on the side of the movable sash 400 near the fixed sash 300. Its power input end is fixedly connected to the transmission rod 450. When the transmission rod 450 moves, it can drive the locking tongue of the locking mechanism to extend or retract, thereby achieving locking or unlocking with the fixed sash 300. The folding screen assembly is movably installed in the second space. When not in use, it can be folded and stored on one side of the second space. When in use, it can be unfolded to cover the entire second space, avoiding the problems of conventional hinged screens blocking the view and affecting lighting.

[0022] Furthermore, the guide groove 441 is opened on the side of the second heat insulation strip 440 away from the first heat insulation strip 430, and the opening position is provided with a snap-fit ​​part 442. When the transmission rod 450 is installed in the guide groove 441, it snaps into the snap-fit ​​part 442.

[0023] Specifically, the guide groove 441 is machined on the end face of the second heat insulation strip 440 away from the first heat insulation strip 430. This position can minimize the damage to the double heat insulation structure formed by the first heat insulation strip 430 and the second heat insulation strip 440 caused by the machining of the guide groove 441, ensuring that the overall heat blocking performance of the heat insulation strip is not affected. At the same time, at the opening edge of the guide groove 441, symmetrically arranged snap-fit ​​parts 442 are integrally formed. The snap-fit ​​parts 442 are arc-shaped protrusions extending into the guide groove 441, which neither hinders the sliding of the transmission rod 450 nor limits the movement of the transmission rod 450.

[0024] When the transmission rod 450 is installed in the guide groove 441, the outer walls on both sides of the transmission rod 450 will fit tightly against the arc-shaped inner wall of the locking part 442, forming a stable locking relationship. This locking structure can prevent the transmission rod 450 from shifting up and down or falling off during the sliding process along the guide groove 441, ensuring that the transmission rod 450 always moves along the preset trajectory, thereby ensuring the stability of the subsequent transmission connection with the locking mechanism; on the other hand, the fit between the locking part 442 and the transmission rod 450 can also reduce the gap between the two, preventing external airflow from entering through the gap, and further helping to improve the sealing and heat preservation effect of the side pressure window.

[0025] Furthermore, the locking mechanism includes a first locking component 460, which comprises: The first fixing locking part 461 is installed on the side of the outer frame 100 away from the fixing fan 300; The first movable locking part 463 is connected to the transmission rod 450 and is connected to the handle 401 via the first positioning plate 462. When the handle 401 rotates, the first movable locking part 463 moves along a first direction to engage with the first fixed locking part 461, and drives the transmission rod 450 to slide in the guide groove 441. The first direction is the direction in which the first profile 410 and the second profile 420 are arranged.

[0026] Specifically, the first fixed locking part 461 is a metal part fixed inside one side of the outer frame 100, and it is provided with a sliding groove. The first movable locking part 463 is provided on the side of the movable fan 400 corresponding to the first fixed locking part 461. In this embodiment, the first movable locking part 463 is a sliding pin, which is connected to the handle 401 through the first positioning plate 462. At the same time, the first positioning plate 462 also plays a role in the transmission between the sliding pin and the handle 401. The sliding pin is held tightly on the transmission rod 450. While the sliding pin is controlled to move by the handle 401, the transmission rod 450 also slides in the guide groove 441, thereby transmitting the action to several other locking components. The transmission structure between the sliding pin and the handle 401 is prior art and will not be described in detail here.

[0027] By rotating the handle 401, the sliding pin can slide in the slide groove, locking the sliding pin and the slide groove, thereby locking the movable fan 400 and the outer frame 100.

[0028] Furthermore, the locking mechanism further includes a second locking component 470, which includes: The second fixing locking part 471 is fixedly installed on the middle muzzle 200; The second positioning plate 472 is fixed at both ends to the first profile 410 and the second profile 420 respectively. The second movable locking part 473 is movably mounted on the second positioning plate 472. When the transmission rod 450 moves, it drives the second movable locking part 473 to slide along the first direction so as to engage with the second fixed locking part 471.

[0029] Specifically, in this embodiment, the second fixed locking part 471 is a hanging plate fixed to the center mullion 200. A second positioning plate 472 is installed on the movable fan 400 at the position corresponding to the second fixed locking part 471. Both ends of the second positioning plate 472 are fixed to the first profile 410 and the second profile 420 respectively by screws. This installation direction improves installation stability compared to the traditional method of installing the locking mechanism on the reinforcing rib between the first profile 410 and the second profile 420, and further secures the first profile 410 and the second profile 420, increasing the connection strength between the profiles. In this embodiment, the second movable locking part 473 is a hook plate, movably installed on the second positioning plate 472. The hook plate can move relative to the second positioning plate 472 through the transmission action of the transmission rod 450. The transmission structure between the hook plate and the transmission rod 450 is prior art and will not be described in detail here.

[0030] When the handle 401 is rotated, the transmission rod 450 transmits the action to the hook plate, causing the hook plate to move closer to the hanging plate and lock with the hanging plate, further locking the movable fan 400 to the outer frame 100.

[0031] Furthermore, the locking mechanism further includes a third locking component 480, which includes: The third fixing locking part 481 is fixedly installed on the top of the outer frame 100 corresponding to the second space; The third positioning plate 482 is fixed at both ends to the first profile 410 and the second profile 420, respectively. The third movable locking part 483 is movably mounted on the third positioning plate 482. When the transmission rod 450 moves, it drives the third movable locking part 483 to move along the first direction so as to engage with the third fixed locking part 481.

[0032] Specifically, in this embodiment, the third fixing locking part 481 is an abutment block fixed to the top of the outer frame 100. A third positioning plate 482 is installed on the movable fan 400 at the position corresponding to the third fixing locking part 481. The installation method of the third positioning plate 482 is the same as that of the second positioning plate 472, both being fixed at both ends to the first profile 410 and the second profile 420 respectively with screws. In this embodiment, the third movable locking part 483 is an abutment joint, which is movably installed on the third positioning plate 482. The abutment joint and the abutment block move relative to each other through the transmission action of the transmission rod 450. The transmission structure between the abutment joint and the transmission rod 450 is prior art and will not be described in detail here.

[0033] When the handle 401 is rotated, the transmission rod 450 transmits the action to the abutment, causing the abutment to move closer to the abutment block and finally abut against the abutment block, further locking the movable fan 400 to the outer frame 100.

[0034] Furthermore, the locking mechanism further includes a fourth locking component 490, which includes: The fourth fixing locking part 491 is fixedly installed on the bottom of the outer frame 100 corresponding to the second space; The fourth positioning plate 492 is fixed at both ends to the first profile 410 and the second profile 420, respectively. The fourth movable locking part 493 is movably mounted on the fourth positioning plate 492. When the transmission rod 450 moves, it drives the fourth movable locking part 493 to move along the first direction so as to engage with the fourth fixed locking part 491.

[0035] Specifically, in this embodiment, the fourth fixing locking part 491 is a protrusion fixed to the bottom of the outer frame 100. A fourth positioning plate 492 is installed on the movable fan 400 corresponding to the fourth fixing locking part 491. The installation method of the fourth positioning plate 492 is the same as that of the second positioning plate 472 and the third positioning plate 482, both ends being fixed to the first profile 410 and the second profile 420 respectively with screws. In this embodiment, the third movable locking part 483 is an abutment wheel. The outer periphery of the abutment wheel has a groove corresponding to the protrusion. The abutment wheel is movably installed on the fourth positioning plate 492. Through the transmission action of the transmission rod 450, the abutment wheel moves relative to the protrusion. The transmission structure between the abutment wheel and the transmission rod 450 is prior art and will not be described in detail here.

[0036] When the handle 401 is rotated, the transmission rod 450 transmits the action to the abutment wheel, causing the abutment wheel to move closer to the protrusion and finally abut against the protrusion, further locking the movable fan 400 to the outer frame 100.

[0037] Furthermore, the transmission rod 450 includes a guide portion 451 and a transmission portion 452. The guide portion 451 is slidably installed in the guide groove 441 and engages with the engaging portion 442. The transmission portion 450 is located on the side of the engaging portion 442 away from the second heat insulation strip 440 and is connected in a transmission manner to the first movable locking portion 463, the second movable locking portion 473, the third movable locking portion 483, and the fourth movable locking portion 493.

[0038] Specifically, the transmission rod 450 is integrally formed from the guide part 451 and the transmission part 452, both made of the same material to ensure structural strength. The cross-section of the guide part 451 is adapted to the guide groove 441 of the second heat insulation strip 440, allowing it to slide smoothly when fully embedded in the groove. Both sides are tightly engaged with the locking parts 442 at the openings of the guide groove 441, preventing dislodgement and ensuring stability. The transmission part 452 is connected to the outside of the guide part 451, positioned on the side of the locking part 442 away from the second heat insulation strip 440, and engages with the movable locking parts of the four locking components for transmission. When the handle 401 moves the transmission rod 450, the transmission part 452 synchronously drives the four movable locking parts to move along the first direction, ensuring that each locking component engages or disengages synchronously, improving locking reliability.

[0039] Furthermore, the second positioning plate 472, the third positioning plate 482 and the fourth positioning plate 492 are all heat insulation plates.

[0040] Specifically, the second positioning plate 472, the third positioning plate 482 and the fourth positioning plate 492 can be made of fiberglass composite thermal insulation material to effectively prevent heat transfer between the first profile 410 and the second profile 420.

[0041] Furthermore, the folding screen assembly includes a folding screen 500, one end of which is fixed to the outer frame 100 via a fixing seat 510, and the other end is equipped with a push-pull handle 520, which is slidably connected to the outer frame 100 and can be engaged with the center mullion 200.

[0042] Specifically, in this embodiment, the foldable mesh 500 is a foldable mesh. One end of the foldable mesh 500 is fixedly installed via a fixing base 510 and tightly secured to the inner wall of the outer frame 100 corresponding to the second space with screws. The fixing base 510 has a mesh folding structure inside, which helps the foldable mesh 500 maintain its neat shape when stored. The other end of the foldable mesh 500 is fixedly connected to the push-pull armrest 520 with rivets. Its outer wall is covered with a non-slip rubber sleeve, which not only makes it convenient for users to grip and apply force, but also prevents hand injuries during operation. The upper and lower ends of the push-pull armrest 520 are also provided with sliders adapted to the slide rails. The sliders are embedded in the preset tracks at the top and bottom of the outer frame 100 corresponding to the second space, so that the push-pull armrest 520 can drive the foldable mesh 500 to slide smoothly along the tracks.

[0043] Furthermore, the folding screen assembly also includes a pair of guide blocks 530, which are respectively installed on the upper and lower sides of the folding screen 500 and are slidably connected to the top and bottom of the outer frame 100.

[0044] Specifically, the two guide blocks 530 are fixed to the upper and lower edges of the folding screen 500 with screws, and are perpendicular to the folding direction of the screen. During installation, the upper guide block 530 is embedded in the elongated groove on the inner top wall of the outer frame 100, and the lower guide block 540 is embedded in the corresponding groove on the inner bottom wall of the outer frame 100, forming a synchronous sliding engagement with the slider of the push-pull handle 520, ensuring that the screen moves in a straight line when unfolding / folding, without deviation or jamming, and ensuring the smooth use of the screen assembly.
