Description

Technical Field

[0001] This invention relates to the field of architectural window technology, and more particularly to a removable and replaceable centrally located louver. Background Technology

[0002] Center-mounted venetian blinds refer to blinds installed within the sealed cavity of double-glazed windows. The slats are retracted, extended, and tilted for light adjustment via an external magnetic structure or an internal motor. Therefore, center-mounted venetian blinds offer excellent sound insulation, heat insulation, and dustproofing, and are widely used in architectural doors and windows. However, because center-mounted venetian blinds contain mechanical components such as pull cords, slats, and connecting cords, they are prone to wear, breakage, and jamming after a certain period of use. Damaged blinds are generally not reused, and they also negatively impact lighting and the building's appearance.

[0003] In existing center-mounted louvered windows, the louver components are all installed within a sealed cavity, which consists of mutually glued glass panels and the window frame. Once a malfunction occurs, repair and replacement are extremely difficult. When such a malfunction occurs, maintenance personnel typically need to disassemble the entire insulated glass unit, sometimes even damaging the original glass sealant layer, resulting in a large workload and high repair costs. Furthermore, after replacement, external equipment is usually needed to inject inert gas to restore a dry, low-oxygen environment within the sealed cavity; however, this process is cumbersome, requires external equipment, and is costly to implement. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a detachable and replaceable central louver to solve the problems of existing central louvers being difficult to disassemble, repair and replace conveniently, and difficult to efficiently restore the sealed and dry low-oxygen environment in the sealed cavity.

[0005] A detachable and replaceable centrally mounted louver includes: a main frame, a first glass panel, a second glass panel, a spacer frame, a movable frame, a closing assembly, and a louver assembly; the movable frame is rotatably connected to the main frame and has two states: open and closed, with a limit groove on the movable frame; the closing assembly includes a mounting frame and a pressure component, the mounting frame being detachably slidably disposed within the limit groove; the louver assembly is disposed within the mounting frame, the louver assembly including a retractable swing component and a slat assembly, the retractable swing component being drively connected to the slat assembly; when the movable frame rotates to the closed state, the mounting frame contacts the spacer frame, and the mounting frame, the first glass panel, the second glass panel, and the spacer frame together form a louver assembly. A sealed cavity is provided, with the louver assembly located inside. A limiting groove guides the sliding direction of the mounting frame perpendicular to the contact surface between the mounting frame and the spacer frame. A pressure-applying component is located on one side of the mounting frame. The pressure-applying component includes a knob, a cam, a transmission block, and a locking tongue. The knob is rotatably mounted on the movable frame, and the cam and locking tongue are fixedly connected to the knob. A locking hole is provided on the main frame. The cam has a protrusion, and the transmission block is fixedly connected to the mounting frame. When the movable frame is in the closed state, and the cam rotates to a preset position, the protrusion applies pressure towards the spacer frame to the mounting frame by squeezing the transmission block. The locking tongue rotates and engages in the locking hole. When the movable frame rotates to the open state, the mounting frame can be removed from the limiting groove.

[0006] Preferably, a purification component is provided inside the sealed cavity. The purification component includes a receiving frame, a dehumidifying block, and a deoxygenating block. A bottom crossbar is provided at the end of the blade assembly away from the retracting and swinging component. A receiving frame is detachably provided on the bottom crossbar. Several independent receiving cavities are opened on the receiving frame. At least one receiving cavity contains a dehumidifying block, and the remaining receiving cavities contain deoxygenating blocks.

[0007] Preferably, the purification component further includes a covering film, one end of which is attached to one side of the receiving frame to seal the receiving cavity, and the other end of which is fixed to the mounting frame.

[0008] Preferably, the purification component further includes a film peeler and a limiting strip; the limiting strip is fixedly connected inside the mounting frame and abuts against the top surface of the bottom crossbar; the film peeler is fixedly connected to the spacer frame; during the rotation of the movable frame, the film peeler contacts the film, and the movable frame continues to rotate so that the film peeler pushes the film to separate from the receiving frame.

[0009] Preferably, the mounting frame is provided with a limiting block, and the mounting frame is detachably and slidably disposed in the limiting groove through the limiting block; a magnetic support block is fixedly connected to the movable frame, and the limiting block is magnetically attracted to the magnetic support block.

[0010] Preferably, the retractable swing component includes a retractable pull rope, a swing pull rope, two first built-in magnetic blocks, and two first external magnetic blocks. The retractable pull rope is fixedly connected to one of the first built-in magnetic blocks, and the swing pull rope is fixedly connected to the other first built-in magnetic block. Both first built-in magnetic blocks are located in a sealed cavity. The first external magnetic blocks and the first built-in magnetic blocks correspond one-to-one and are magnetically attracted to each other through a second glass plate. Two guide rails are provided in the spacer frame, and a first built-in magnetic block is slidably connected in each guide rail.

[0011] Preferably, the retractable swing component further includes two winding wheels, two second internal magnetic blocks, and two second external magnetic blocks; each second internal magnetic block is rotatably connected to a winding wheel, the retractable pull rope is wound around one of the winding wheels, and the swing pull rope is wound around the other winding wheel; both second internal magnetic blocks are located in a sealed cavity, the second external magnetic blocks and the second internal magnetic blocks correspond one-to-one and are magnetically attracted to each other through the second glass plate, and each guide rail is slidably connected to a second internal magnetic block.

[0012] Preferably, a sealing ring is provided on one side of the mounting frame or the spacer frame, and when the mounting frame moves to a position close to the spacer frame, the sealing ring fills the gap between the mounting frame and the spacer frame.

[0013] Beneficial effects: (1) By unlocking and rotating the movable frame, maintenance personnel can repair or replace the louver assembly. When the movable frame is rotated back to the closed state and the mounting frame is in contact with the spacer frame again, the pressure component applies pressure to the mounting frame towards the spacer frame so that the mounting frame and the spacer frame are in closer contact. Thus, after replacing the louver assembly, the sealed cavity can still be restored to a sufficient sealing state. In this way, through the rotatable movable frame and the sliding mounting frame, when the louver fails, only the movable frame needs to be opened to replace the entire mounting frame with the louver assembly. The whole process does not require disassembling the glass plate, realizing the quick replacement of the central louver, which greatly reduces the difficulty of maintenance and maintenance costs.

[0014] (2) When the movable frame is rotated to the closed state, the knob is turned so that the protrusion squeezes the transmission block to apply pressure to the mounting frame toward the spacer frame. At this time, the locking tongue rotates and engages in the lock hole. Thus, the locking tongue and the lock hole cooperate to fix the movable frame, and at the same time, the mounting frame and the spacer frame fit more tightly. Through the linkage design of the knob driving the cam and the locking tongue, the maintenance personnel can complete the locking of the movable frame efficiently and quickly with just one rotation operation, and enclose the louver assembly in the sealed cavity, thereby completing the replacement of the central louver more efficiently.

[0015] (3) When the movable frame rotates to the closed state, the dehumidifying block and the deoxygenating block are located in the sealed cavity. The dehumidifying block is used to remove water vapor in the sealed cavity, and the deoxygenating block is used to remove oxygen in the sealed cavity, thereby ensuring that the sealed cavity maintains a dry and low-oxygen environment to prevent the glass from fogging and condensation, and effectively prevents the oxidation of the metal parts of the louvers, significantly extending the product life. In addition, the film is used to block outside air from directly entering the receiving cavity to avoid the dehumidifying block and deoxygenating block in the receiving cavity from failing. When the movable frame rotates from the open state to the closed state, the film peeler touches the film, and then the movable frame continues to rotate so that the film peeler pushes the film to separate from the receiving frame. In this way, the film peeling is completed during the closing process of the movable frame, reducing assembly steps, improving assembly efficiency, and improving the utilization rate of the dehumidifying block and deoxygenating block.

[0032] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of this invention, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] A type of removable and replaceable center-mounted louver, such as Figures 1-4 and Figure 9 As shown, it includes: a main frame 10, a first glass panel 20, a second glass panel 30, a spacer frame 40, a movable frame 50, a closing assembly 60, and a louver assembly 70; the main frame 10 is a rectangular frame, on which the first glass panel 20 and the second glass panel 30 are provided. The first glass panel 20 is a double-glazed unit with excellent sound insulation. A spacer frame 40 is fixed between the first glass panel 20 and the second glass panel 30; the outer edges of the first glass panel 20, the second glass panel 30, and the spacer frame 40 are flush with each other; a through groove 41 is opened on the spacer frame 40; the lower edge of the movable frame 50 is rotatably connected to the main frame 10, and the movable frame 50 has two states: open and closed. A limit groove 52 is opened on the movable frame 50.

[0037] like Figures 4-9 and Figure 15As shown, the closure assembly 60 includes a mounting frame 61 and a pressurizing component 63. A limiting block 611 is provided on the mounting frame 61, and the mounting frame 61 is slidably disposed within the limiting groove 52 via the limiting block 611. A louver assembly 70 is disposed within the mounting frame 61. The louver assembly 70 includes a retractable swing component 71 and a slat assembly 72. The retractable swing component 71 is pulsatorically connected to the slat assembly 72 to drive the slat assembly 72 to retract, unfold, and swing for dimming. When the movable frame 50 rotates to the closed state, the mounting frame 61 contacts the spacer frame 40, securing the louver. The mounting frame 61, the first glass plate 20, the second glass plate 30, and the spacer frame 40 together form a sealed cavity, and the upper and lower parts of the sealed cavity are connected by the through groove 41; the louver assembly 70 is located inside the sealed cavity; the limiting groove 52 guides the sliding direction of the mounting frame 61 to be perpendicular to the contact surface between the mounting frame 61 and the spacer frame 40; the pressure-applying component 63 is provided on one side of the mounting frame 61 to apply pressure to the mounting frame 61 toward the spacer frame 40; when the movable frame 50 is rotated to the open state, the mounting frame 61 can be removed from the limiting groove 52.

[0038] Specifically, the control line on the sheet group 72 is connected to the retractable swing component 71. The retractable swing component 71 drives several sheets in the sheet group 72 to retract and swing through the traction control line. The retractable swing component 71 is divided into electric and manual types. When using the electric retractable swing component 71, the retractable swing component 71 only needs to control the rotation of the internal motor to drive several sheets to retract and swing. When using the manual retractable swing component 71, the retractable swing component 71 is equipped with a pull rope. The pull rope drives several sheets to retract and swing. Since the pull rope is usually located between two glass plates, magnetic blocks are used to provide traction force between the glass plates. This is a common control method in the prior art and will not be described in detail.

[0039] During normal use, the movable frame 50 rotates to the closed state and locks, and the mounting frame 61 is in close contact with the spacer frame 40. The mounting frame 61, the first glass plate 20, the second glass plate 30, and the spacer frame 40 together form a sealed cavity. The retraction and swinging component 71 drives the leaf assembly 72 to retract, expand, and swing within the sealed cavity to adjust light, thereby achieving the purpose of shading or changing the amount of light entering. In the event of a malfunction of the venetian blind assembly 70, by unlocking and rotating the movable frame 50, causing the movable frame 50 to rotate 180 degrees, as shown... Figure 2In the indicated state, the louver assembly 70 is detached from the sealed cavity, allowing maintenance personnel to repair it. When the louver assembly 70 needs to be replaced, the mounting frame 61 is removed from the limiting groove 52, along with the louver assembly 70. Then, the maintenance personnel install the new mounting frame 61 and the louver assembly 70 into the movable frame 50, and the limiting block 611 on the mounting frame 61 is reinstalled into the limiting groove 52. The movable frame 50 is then rotated back to the closed state and locked, and the mounting frame 61 is once again in close contact with the spacer frame 40.

[0040] When the movable frame 50 rotates back to the closed state and the mounting frame 61 comes into contact with the spacer frame 40 again, pressure is applied to the mounting frame 61 toward the spacer frame 40 by the pressure-applying component 63. It should be noted that when the pressure-applying component 63 applies pressure to the mounting frame 61 toward the spacer frame 40, the mounting frame 61 moves slightly toward the spacer frame 40, but the limiting block 611 on the mounting frame 61 cannot disengage from the limiting groove 52. This allows the mounting frame 61 to fit more tightly with the spacer frame 40, so that after replacing the louver assembly 70, the sealing cavity can still be restored to a sufficient sealing state. Thus, through the rotatable movable frame 50 and the sliding mounting frame 61, when the louver malfunctions, only the movable frame 50 needs to be opened to replace the entire mounting frame 61 with the louver assembly 70 installed. The whole process does not require disassembling the glass panel, realizing the quick replacement of the centrally located louver, greatly reducing the difficulty of inspection and maintenance costs.

[0041] Specifically, the pressurizing component 63 can also be an elastic component, with one end abutting against the main frame 10 and the other end abutting against the mounting frame 61; the pressurizing component 63 can also be a telescopic component, which is installed on the main frame 10 and abuts against the mounting frame 61 after it extends.

[0042] More preferably, such as Figures 4-9 and Figure 15As shown, the pressurizing component 63 includes a knob 631, a cam 632, a transmission block 633, and a locking tongue 634. The knob 631 is rotatably mounted on the movable frame 50. The cam 632 and the locking tongue 634 are fixedly connected to the knob 631. The main frame 10 has a locking hole 11 corresponding to the locking tongue 634. The cam 632 has a protrusion 6321 with a first flat surface. The transmission block 633 is fixedly connected to the mounting frame 61. When the movable frame 50 is in the closed state and the cam 632 rotates... When the preset position is reached, the protrusion 6321 presses the transmission block 633 to apply pressure toward the spacer frame 40 to the mounting frame 61. The transmission block 633 radially abuts against the protrusion 6321 to restrict the rotation of the cam 632. The transmission block 633 is provided with a second plane corresponding to the first plane. The first plane and the second plane abut against each other. The two ends of the first plane are located on both sides of the rotation center of the cam 632. At this time, the torque on the cam 632 is zero. At this time, the locking tongue 634 rotates and engages in the locking hole 11.

[0043] When the movable frame 50 is rotated to the closed state, the knob 631 is rotated to cause the protrusion 6321 to press the transmission block 633, thereby applying pressure to the mounting frame 61 toward the spacer frame 40. At this time, the locking tongue 634 rotates and engages in the lock hole 11. Thus, the locking tongue 634 and the lock hole 11 cooperate to fix the movable frame 50, while making the mounting frame 61 and the spacer frame 40 fit more tightly. Through the linkage design of the knob 631 driving the cam 632 and the locking tongue 634, maintenance personnel can efficiently and quickly lock the movable frame 50 and seal the louver assembly 70 in the sealed cavity with only a single rotation operation, thereby completing the replacement of the central louver more efficiently.

[0044] More preferably, such as Figure 4 , Figure 6 , Figure 9 and Figure 10 As shown, a purification component 80 is provided inside the sealed cavity. The purification component 80 includes a receiving frame 81, a dehumidifying block 82, and a deoxygenating block 83. A bottom crossbar 73 is provided at the end of the blade assembly 72 away from the retracting swing component 71. The receiving frame 81 is detachably provided on the bottom crossbar 73. Specifically, the receiving frame 81 is snapped onto the bottom crossbar 73 by a clip 812. The receiving frame 81 has several independent receiving cavities 811, of which at least one receiving cavity 811 contains a dehumidifying block 82, and the remaining receiving cavities 811 contain deoxygenating blocks 83.

[0045] Specifically, the accommodating frame 81 has two independent accommodating cavities 811, which can exchange heat. One accommodating cavity 811 contains a dehumidifying block 82, and the other accommodating cavity 811 contains a deoxygenating block 83. The dehumidifying block 82 is mainly composed of non-woven fabric and 3A molecular sieve powder, with the non-woven fabric wrapping the 3A molecular sieve powder. The deoxygenating block 83 is mainly composed of non-woven fabric and a water-self-sufficient deoxidizer, with the non-woven fabric wrapping the water-self-sufficient deoxidizer. During the dehumidification and deoxygenation reaction, the 3A molecular sieve powder absorbs water and reacts exothermically, while the water-self-sufficient deoxidizer reacts faster when heated, thus promoting each other to achieve more efficient dehumidification and deoxygenation. It should be noted that the volume of the accommodating cavity 811 should be slightly larger than that of the dehumidifying block 82 and the deoxygenating block 83 to ensure that the dehumidifying block 82 and the deoxygenating block 83 do not overflow from the accommodating cavity 811 after the reaction expansion.

[0046] When the movable frame 50 is rotated to the closed state, the dehumidifying block 82 and the deoxygenating block 83 are located in the sealed cavity. The dehumidifying block 82 is used to remove water vapor in the sealed cavity, and the deoxygenating block 83 is used to remove oxygen in the sealed cavity, thereby ensuring that the sealed cavity maintains a dry and low-oxygen environment to prevent the glass from fogging and condensing, and effectively prevents the oxidation of the metal parts of the louvers, significantly extending the product life.

[0047] More preferably, such as Figure 9 As shown, the purification component 80 also includes a covering film 84, one end of which is attached to one side of the receiving frame 81 to seal the receiving cavity 811, and the other end of which is fixed to the mounting frame 61.

[0048] By applying a covering film 84 to prevent outside air from directly entering the receiving cavity 811, the dehumidifying block 82 and deoxygenating block 83 inside the receiving cavity 811 are prevented from becoming ineffective. After installing the new mounting frame 61 and louver assembly 70, the covering film 84 is peeled off so that the covering film 84 no longer seals the receiving cavity 811. Then, the movable frame 50 is rotated to the closed state to complete the replacement and sealing of the central louver, thereby ensuring the effective use of the dehumidifying block 82 and deoxygenating block 83.

[0049] More preferably, such as Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 14 As shown, the purification component 80 also includes a film peeling sheet 85 and a limiting strip 86; the limiting strip 86 is fixedly connected to the mounting frame 61 and abuts against the top surface of the bottom crossbar 73; the film peeling sheet 85 is fixedly connected to the spacer frame 40; during the rotation of the movable frame 50, the film peeling sheet 85 contacts the covering film 84, and the movable frame 50 continues to rotate so that the film peeling sheet 85 pushes the covering film 84 to separate from the receiving frame 81.

[0050] When the movable frame 50 rotates from the open state to the closed state, the film peeler 85 contacts the covering film 84. Then the movable frame 50 continues to rotate, so that the film peeler 85 pushes the covering film 84 to separate from the receiving frame 81. The limiting strip 86 abuts against the top surface of the bottom crossbar 73 to prevent the receiving frame 81 from moving upward, ensuring that the covering film 84 separates smoothly from the receiving frame 81. In this way, the covering film 84 is peeled off during the closing process of the movable frame 50, reducing assembly steps, improving assembly efficiency, and increasing the utilization rate of the dehumidification block 82 and the deoxygenation block 83.

[0051] More preferably, such as Figure 4 , Figure 6 and Figure 15 As shown, a magnetic support block 51 is fixedly attached to the movable frame 50, and a limiting block 611 is magnetically attached to the magnetic support block 51; in this embodiment, the limiting groove 52 is located on the magnetic support block 51 of the movable frame 50.

[0052] To facilitate the disassembly of the mounting frame 61, the mounting frame 61 and the louver assembly 70 are installed when the magnetic support block 51 and the limiting block 611 are magnetically attached. When the pressure member 63 applies a force toward the spacer frame 40 to the mounting frame 61, causing it to move slightly, the magnetic support block 51 disengages from the limiting block 611. When the pressure member 63 stops applying pressure toward the spacer frame 40 to the mounting frame 61, the magnetic support block 51 and the limiting block 611 re-magnetically attach.

[0053] More preferably, such as Figure 3 , Figure 11 , Figure 12 and Figure 13 As shown, when the manual retractable swing component 71 is selected, the retractable swing component 71 includes a retractable pull rope 711, a swing pull rope 712, two first internal magnetic blocks 714, and two first external magnetic blocks 715; the retractable pull rope 711 is fixedly connected to one of the first internal magnetic blocks 714, specifically, both ends of the retractable pull rope 711 pass through the first internal magnetic block 714, with only one end fixedly connected to the first internal magnetic block 714; the swing pull rope 712 is fixedly connected to the other first internal magnetic block 714, specifically, both ends of the swing pull rope 712 pass through the other first internal magnetic block 714, specifically, both ends of the swing pull rope 712 pass through the other first internal magnetic block 714, specifically, both ends of the swing pull rope 712 pass through the other first internal magnetic block 714, specifically, both ends of the swing pull rope 715 ... The first built-in magnetic block 714 is passed through, with only one section fixed to the first built-in magnetic block 714; both first built-in magnetic blocks 714 are located in the sealed cavity, and the first external magnetic block 715 and the first built-in magnetic block 714 correspond one-to-one and are magnetically attracted to each other through the second glass plate 30; the spacer frame 40 is provided with two guide rails 43, and each guide rail 43 is slidably connected to a first built-in magnetic block 714. In order to facilitate picking up and putting down, the first built-in magnetic block 714 includes several small magnetic blocks, and the small magnetic blocks are connected from top to bottom through flexible connectors.

[0054] After installing the mounting frame 61 and the venetian blind assembly 70 into the movable frame 50, the first built-in magnetic block 714 is placed into the guide rail 43. Then, the movable frame 50 is rotated to the closed state, and the first external magnetic block 715 is placed on the side of the second glass plate 30 away from the first built-in magnetic block 714 to complete the installation of the first built-in magnetic block 714 and the first external magnetic block 715, so that the present invention can be used for manually pull-cord type venetian blinds.

[0055] More preferably, such as Figure 3 , Figure 11 , Figure 12 and Figure 13 As shown, the retractable swing component 71 also includes two winding wheels 713, two second built-in magnetic blocks 716, and two second external magnetic blocks 717; each second built-in magnetic block 716 is rotatably connected to a winding wheel 713, the retractable pull rope 711 is partially wound around one of the winding wheels 713, and the swing pull rope 712 is partially wound around the other winding wheel 713; both second built-in magnetic blocks 716 are located in a sealed cavity, the second external magnetic blocks 717 and the second built-in magnetic blocks 716 correspond one-to-one and are magnetically attracted to each other through the second glass plate 30, and each guide rail 43 is slidably connected to a second built-in magnetic block 716.

[0056] After installing the mounting frame 61 and the louver assembly 70 into the movable frame 50, first place the second built-in magnetic block 716 and the winding wheel 713 into the guide rail 43, then place the first built-in magnetic block 714 into the guide rail 43, and then rotate the movable frame 50 to the closed state. Place the second external magnetic block 717 on the side of the second glass plate 30 away from the second built-in magnetic block 716. The winding wheel 713 is supported by the magnetic attraction of the second built-in magnetic block 716 and the second external magnetic block 717. Move the second external magnetic block 717 to drive the second built-in magnetic block 716 downward, so that the retractable pull rope 711 and the swing pull rope 712 are tightened. Compared with the traditional bolt and support to support the winding wheel 713, it has the advantages of quick installation and removal and no need to remove the glass plate during replacement.

[0057] The structure of this invention can accommodate both the electric retraction and swing component 71 and the traditional manual pull-rope retraction and swing component 71, thus meeting the application needs of different grades and scenarios without complicated modifications.
