Abstract

The application provides a universal anti-rollover louver turner and hollow louver glass using the same. The turner and the lifter are both installed inside an aluminum groove at the edge of the inner cavity of the hollow glass, and comprise a main body, a magnet and a roller. The main body comprises a magnet groove and roller grooves at both ends of the magnet groove. The magnet is installed in the magnet groove, and the roller is installed in the roller groove. New wire grooves are added to both sides of the turner. The new wire grooves increase the width of the turner and make the gap between the turner and the track smaller. When the vertical louver is combined, the problem of self-rotation of the turner during the combination of the vertical hollow louver is solved, and the hidden danger of production failure during the combination of the vertical louver is solved. The design of the double wire grooves makes the turner more versatile, and multiple molds are not needed, thereby reducing the production cost.

Description

Technical Field

[0001] The present invention relates to the field of manufacturing of louvered hollow glass, and in particular to a universal louver flipper capable of resisting self-rollover and hollow louvered glass using the same. Background Art

[0002] As market demand for large-sized internal louvered glass increases, its structure, production equipment, and materials are constantly being improved. Dual-control internal louvered glass features two controllers: one for controlling the raising and lowering of the louver, known as the lifter; the other for controlling the tilting angle of the louver blades, known as the flipper. The aluminum profile spacers, which seal and support the edges of the insulating glass, have aluminum grooves that double as tracks for mounting the lifter and flipper. The lifter or flipper moves within the grooves to control the raising and lowering or flipping of the louver.

[0003] Existing flippers, when used on large-sized Venetian blinds, present the following problems: 1. Existing flippers typically only have two magnets, and the compatible built-in Venetian blinds are relatively small. This makes adjustment difficult and prone to demagnetization when used on large Venetian blinds. 2. If the lifter and flipper are located on the same side of the Venetian blind, the flipper mold requires a wire guide to pass the lifter's cord through and prevent it from becoming entangled with the flipper's cord. However, during actual production and assembly, the lifter and flipper are installed on the left and right sides of the Venetian blind, respectively. Therefore, the flipper's wire guides need to be located on different sides. Different molds and assembly methods prevent universal compatibility, resulting in high production costs and a high probability of operator error during assembly. 3. Since the flipper is slotted on one side and is small in size, there is a large gap between it and the inner wall of the aluminum groove of the hollow louver glass. The original design was for horizontal hollow louver assembly. When the new production method is vertical louver assembly, the flipper will tip over or even completely turn downward due to its own gravity during the assembly process, causing the entire louver system to malfunction, unable to be assembled or the flipper to be unusable. Summary of the Invention

[0004] The present invention aims to solve the shortcomings of the prior art flippers in large-sized blinds and hollow blinds, and proposes a universal blind flipper that resists self-rollover and a hollow blind using the same.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A universal blind flipper that resists self-rollover. The flipper and lifter are cooperatively installed inside a profile spacer at the edge of the inner cavity of a hollow glass. The cavity inside the profile spacer serves as a track. The flipper and lifter are movably arranged in the track. The flipper includes a main body, a magnet, and a roller. The main body includes a magnet slot and roller slots located at both ends of the magnet slot. The magnet is installed in the magnet slot. The length of the magnet slot is not less than the sum of the lengths of three magnets. The roller is installed in the roller slot. When the flipper moves in the track, the roller rolls on the glass sheet along the extension direction of the track.

[0007] The left and right sides of the main body are provided with wire grooves, which are used to pass the pull rope of the lifter and increase the width of the main body; the wire groove on the left side of the flipper is used to pass the pull rope of the lifter when the flipper and the lifter are both located in the left track of the insulating glass; the wire groove on the right side of the flipper is used to pass the pull rope of the lifter when the flipper and the lifter are both located in the right track of the insulating glass; the sum of the gap widths between the left and right sides of the flipper and the track is less than one-third of the thickness of the flipper itself. When the insulating glass undergoes a vertical assembly process, the main body of the flipper swings in the track and returns to its skewed position due to the collision and obstruction of the inner wall of the track.

[0008] Preferably, the magnet slot comprises n magnet grids arranged along the extension direction of the track, wherein n is a natural number and n≥3, and at most one magnet is placed in each magnet grid.

[0009] Preferably, a metal sheet is provided at the bottom of the magnet slot, all the magnet grids are located above the metal sheet, and the magnets are placed in the magnet grids and adsorbed on the metal sheet.

[0010] Preferably, the wire groove is integrally opened on the left and right sides of the roller groove.

[0011] Preferably, the roller grooves at the upper and lower ends of the main body are provided with wire grooves on both the left and right sides.

[0012] Preferably, the sum of the gap widths between the left and right sides of the flipper and the track is 1-5 mm.

[0013] Preferably, a first hanging ear is provided at the top end of the main body, and a second hanging ear is provided at the bottom end of the main body. The first hanging ear and the second hanging ear are both tied with a draw rope and enable the flipper to move up and down in the track to flip the blades of the venetian blind.

[0014] Preferably, the shape of the first hanging ear is different from the shape of the second hanging ear.

[0015] A hollow louver glass comprises the universal louver flipper for resisting self-rollover as described in any one of the above items.

[0016] Preferably, a double-sided track is provided inside the cavity formed by the two sheets of glass, and the lifter and the universal blind flipper include the following mounting structure:

[0017] The lifter and the universal shutter flipper are installed together on one of the two side tracks, and the pull rope of the lifter passes through the wire groove of the universal shutter flipper on the same side as the one of the tracks;

[0018] Alternatively, the lifter and the universal shutter flipper are respectively installed in double-sided tracks, the lifter is installed on one of the double-sided tracks, and the universal shutter flipper is installed on the other of the double-sided tracks.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By increasing the size of the magnet slot, it can be compatible with the existing 2-magnet configuration. At the same time, magnets can be added to expand the configuration to 3, 4 or more magnets, which can adapt to larger areas of blinds.

[0021] New wire grooves are added on both sides of the flipper of the present invention. If the lifter and the flipper are located on different sides, the wire groove of the flipper can be left empty; if the lifter and the flipper are both located on the left side track of the louver glass, the pull rope of the lifter passes through the left side wire groove of the flipper; if the lifter and the flipper are both located on the right side track of the louver glass, the pull rope of the lifter passes through the right side wire groove of the flipper; the design of double wire grooves allows the flipper to be used universally in the tracks on both sides of the louver glass, without the need to open multiple molds, thereby reducing production costs.

[0022] The newly added wire groove increases the width of the flipper and reduces the gap between it and the track. During vertical assembly, the problem of the flipper self-rotating during vertical hollow louver assembly is solved, thereby solving the hidden trouble of production during vertical assembly.

[0031] Among them, there are a flipper 100, a lifter 200, a left track 301, a right track 302; a main body 1, a magnet 2, a roller 3, a magnet slot 11, a roller slot 12, a wire slot 13, a magnet grid 111, a metal sheet 112, a first hanging ear 141, and a second hanging ear 142. DETAILED DESCRIPTION

[0032] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0033] Please refer to Figures 1-4 The present invention provides a universal blind flipper that resists self-rollover. The flipper 100 and the lifter 200 are installed in cooperation with the profile spacer at the edge of the inner cavity of the insulating glass. The cavity in the profile spacer serves as a track. The flipper 100 and the lifter 200 are movably arranged in the track. The flipper includes a main body 1, a magnet 2, and a roller 3. The main body 1 includes a magnet slot 11 and roller slots 12 located at both ends of the magnet slot 11. The magnet 2 is installed in the magnet slot 11. The length of the magnet slot 11 is not less than the sum of the lengths of the three magnets 2. The roller 3 is installed in the roller slot 12. When the flipper 100 moves in the track, the roller 3 rolls on the glass sheet along the extension direction of the track.

[0034] A wire groove 13 is provided on both the left and right sides of the main body 1. The wire groove 13 is used to pass the pull cord of the lifter 200 and increase the width of the main body 1. The wire groove 13 on the left side of the flipper 100 is used to allow the pull cord of the lifter 200 to pass through when the flipper 100 and the lifter 200 are both located in the left track 301 of the insulating glass. The wire groove 13 on the right side of the flipper 100 is used to allow the pull cord of the lifter 200 to pass through when the flipper 100 and the lifter 200 are both located in the right track 302 of the insulating glass. The sum of the gap widths between the left and right sides of the flipper 100 and the track is less than one-third of the thickness of the flipper 100 itself. When the insulating glass undergoes a vertical assembly process, the main body 1 of the flipper 100 swings in the track and is blocked by the inner wall of the track to return to its skewed position.

[0035] The size of the magnet slot 11 of the flipper 100 of the present invention is increased compared to the traditional flipper 100. The traditional flipper 100 is equipped with two magnets 2, while the flipper 100 of the present invention can be expanded to accommodate three, four or more magnets 2 in the magnet slot 11, which is more suitable for large-sized blinds and has stronger magnetic force, so the magnetic handle is not easy to fall off.

[0036] The flipper 100 of the present invention has wire guides 13 on both the left and right sides of the main body 1, creating a double-sided wire guide structure. When the lifter 200 and the flipper 100 are installed on the same side, the pull cord of the lifter 200 must be routed outside the flipper 100. Therefore, when the lifter 200 and the flipper 100 are simultaneously installed on the left side of the insulating glass track, the pull cord of the lifter 200 can be routed through the left wire guide 13 of the flipper 100. When the lifter 200 and the flipper 100 are simultaneously installed on the right side of the insulating glass track, the pull cord of the lifter 200 can be routed through the right wire guide 13 of the flipper 100. Therefore, the flipper 100 of the present invention has enhanced versatility and is suitable for various installation schemes. The flipper 100 of the present invention can be used uniformly in the production of the various types of insulating glass described above, eliminating the need for separate mold production, significantly reducing production costs, and also reducing the risk of mismatching during assembly of the flipper 100.

[0037] The flipper 100 of the present invention has a larger width of the main body 1 than the traditional flipper 100 because of the addition of the wire groove 13, and the gap between the main body 1 and the track is smaller. Therefore, during vertical assembly, the flipper 100 will shake due to its own gravity. However, since the gap is too small, after swinging to a certain angle, it will touch the inner wall of the track on which it is located, preventing the flipper 100 from tipping over and returning it to the right position in time, avoiding the flipper 100 from self-rotating or even turning upside down, solving the hidden dangers of vertical assembly, and thus ensuring that vertical assembly can be completed smoothly.

[0038] In one embodiment, the magnet slot 11 includes n magnet grids 111 arranged along the extension direction of the track, where n ≥ 3. At most one magnet 2 is placed in each magnet grid 111, which facilitates the installation of the magnets 2 and isolates each magnet 2 to prevent the magnets 2 from adsorbing each other and moving in the magnet slot 11 when the total length of the magnets 2 is less than the total length of the magnet slot 11.

[0039] In a more preferred embodiment, a metal sheet 112 is provided at the bottom of the magnet slot 11, and all the magnet grids 111 are located above the metal sheet 112. The magnet 2 is placed in the magnet grid 111 and adsorbed on the metal sheet 112, further fixing the position of the magnet 2 and improving the adsorption and fixing effect of the magnet 2 in the magnet slot 11. At the same time, the detachable installation feature of the magnet 2 is maintained, which facilitates the installation and replacement of the magnet 2. The number of magnets 2 can be flexibly set according to the use requirements of blinds of different sizes, thereby enhancing the versatility of the flipper 100.

[0040] In one embodiment, the wire groove 13 is integrally formed on the left and right sides of the roller groove 12. In the conventional flipper 100, the roller groove 12 is the same width as the magnet groove 11 and extends integrally from both ends of the magnet groove 11. The wire groove 13 of the present invention can be widened at both ends of the conventional roller groove 12, and the wire groove 13 is symmetrically formed on the left and right sides of the widened portion. The newly added wire groove 13 is then located entirely outside the magnet groove 11, making it easy for the pull rope to pass through, and can effectively separate the ropes, thereby preventing the pull ropes of the lifter 200 and the pull ropes of the flipper 100 from getting entangled with each other. In addition, the above structure increases the width of the roller grooves 12 at the upper and lower ends of the flipper 100, reducing the gap between the roller grooves 12 and the track, thereby effectively preventing the flipper 100 from tipping over or flipping downward due to gravity when the flipper 100 is vertically assembled, and preventing the entire blind system from malfunctioning after vertical assembly.

[0041] Furthermore, the roller grooves 12 at the upper and lower ends of the main body 1 have wire grooves 13 on both the left and right sides. When the lifter 200 and the flipper 100 are located on the same side, the pull rope of the lifter 200 needs to pass through the upper and lower wire grooves 13 regardless of whether it passes through the wire groove 13 on the left or right side of the flipper 100, so that the pull rope is effectively limited at two points, avoiding the pull rope from shaking and entanglement, and achieving a better rope separation effect.

[0042] In a preferred embodiment, the sum of the gap widths between the left and right sides of the flipper 100 and the track is 1-5 mm, which can effectively prevent the flipper 100 from tipping over and flipping during vertical assembly, allowing it to return to the center position in time after shaking, and ensure the smoothness of the flipper 100 sliding in the track.

[0043] In one embodiment, a first lug 141 is provided at the top of the main body 1, and a second lug 142 is provided at the bottom of the main body 1. Both the first lug 141 and the second lug 142 are connected to a draw cord, allowing the flipper 100 to move up and down within the track to flip the blades of the Venetian blind. Furthermore, the shape of the first lug 141 and the second lug 142 can be different, with one end being arc-shaped and the other end being square, which effectively prevents fools. The flipper 100 of the present invention can be used for the left track 301 or the right track 302 of the hollow louver glass, but the upper and lower ends of the flipper 100 need to be accurately installed on the tracks on different sides. In the actual assembly process, since the traditional flipper 100 is a symmetrical structure up and down, it is difficult to distinguish the upper and lower ends. It is very easy for the upper and lower ends of the flipper 100 to be installed upside down, affecting the flipping effect of the louver. The upper and lower ears of the flipper 100 of the present invention have different shapes. In this way, no matter which side of the track of the hollow louver glass the flipper 100 needs to be installed on, the ears of a certain shape are fixed at the top during assembly, and the ears of another shape are fixed at the bottom during assembly. The installer only needs to quickly and accurately install the flipper 100 according to the shape of the ears, which greatly reduces the error rate of installation.

[0044] Please refer to Figure 5-Figure 8 The present invention also protects a type of hollow louvered glass, specifically a type of hollow louvered glass with a venetian blind. The louver's lifting and lowering control is achieved using a lifter 200, and the louver's blade angle is controlled using a universal louver flipper 100 of the present invention, which resists self-rollover. This dual-control hollow louvered glass has dual tracks within the cavity formed by the two panes of glass. The profile spacers within the hollow glass are hollow structures, with the left and right profile spacers serving as dual tracks. The lifter 200 and the universal louver flipper 100 comprise the following mounting structure:

[0045] The lifter 200 and the universal shutter flipper 100 are installed together on one of the two-sided tracks, and the pull rope of the lifter 200 passes through the wire groove 13 of the universal shutter flipper 100 on the same side as the one of the tracks;

[0046] Alternatively, the lifter 200 and the universal shutter reversing device 100 are respectively installed in the double-sided tracks, the lifter 200 is installed on one of the double-sided tracks, and the universal shutter reversing device 100 is installed on the other of the double-sided tracks.

[0047] First, please refer to Figure 5 The lifter 200 and the universal blind flipper 100 are located together on the right track 302. The pull rope of the lifter 200 needs to pass through the wire groove 13 on the right side of the flipper 100, and the wire groove 13 on the left side of the flipper 100 is empty.

[0048] Second, please refer to Figure 6 The lifter 200 and the universal blind flipper 100 are located together on the left track 301. The pull rope of the lifter 200 needs to pass through the wire groove 13 on the left side of the flipper 100, and the wire groove 13 on the right side of the flipper 100 is empty.

[0049] Third, please refer to Figure 7 , the lifter 200 is installed on the left track 301, the universal shutter flipper 100 is installed on the right track 302, and the wire grooves 13 on the left and right sides of the flipper 100 are empty;

[0050] Fourth, please refer to Figure 8 The lifter 200 is installed on the right track 302, and the universal shutter flipper 100 is installed on the left track 301. The wire grooves 13 on the left and right sides of the flipper 100 are both empty.

[0051] The above-mentioned hollow louver glasses with different installation structures can all adopt the universal louver flipper 100 of the present invention. There is no need to replace the flippers 100 of different models. The production cost is low, and the assembly process is simpler and more accurate. The flipper 100 can be effectively prevented from tipping over during vertical assembly, and the failure rate is effectively reduced.

[0052] As described above, the universal blind flipper that resists self-tipping of the present invention improves the structure of the traditional flipper, increases the length of the magnet slot and thus increases the number of magnets that can be placed, making it more suitable for large-sized hollow blind glass; by adding wire grooves on both sides of the traditional flipper, it can be installed in any track on the left and right sides of the hollow blind glass, has stronger versatility, and does not require changing or adding any assembly process, and at the same time has the effect of increasing the width of the flipper body, so that the gap between it and the track is smaller, which solves the problem that the flipper is prone to self-tipping, flipping over, and flipping out of the track in the track during vertical splicing, resulting in the inability to complete vertical splicing, or the flipper cannot be used after splicing; at the same time, since the flipper of the present invention is more versatile and can be installed in the track on either side of the hollow glass, but the accuracy of its installation direction directly affects the use effect of the flipper, the hanging ears at the upper and lower ends of the flipper are also designed with anti-foolproof design to help assembly workers quickly distinguish the installation direction of the flipper and improve installation accuracy. The universal blind flipper protected by the present invention, through minor structural improvements and adjustments, does not add any assembly steps and even simplifies the assembly difficulty, while achieving the effects of improving versatility, adapting to large-sized insulating glass, reducing the probability of self-rolling, and improving the success rate of vertical assembly.

[0053] In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0054] The present application has been described by the above-mentioned related embodiments, however the above-mentioned embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, modifications and improvements made without departing from the spirit and scope of the present application are within the scope of the patent protection of the present application.
