Abstract

(57) Abstract The glazing unit of the present invention includes four peripheral groove members that are joined to a corner member to form a glazing frame. The two glass panels are spaced apart by this frame to form an inner chamber, within which the venetian blind structure of the present invention is completely disposed. The venetian blind structure comprises a plurality of horizontal slats pivotally supported at a distal end thereof, each having an integral gear engaging a complementary shelf on an actuator bar, the integral gear Is disposed adjacent to the peripheral groove member on the side surface, and further freely moves up and down along the peripheral groove member. This vertical movement imparts a slat to the slat. Furthermore, the venetian blind structure comprises a support groove member for supporting a reversible electric motor having a drive shaft. This shaft is suitably arranged to engage the actuator bar. As the drive shaft rotates, the drive shaft imparts a linear up and down motion to the actuator bar, thereby causing the slat to pivot. Positioning of the shaft is provided by an L-shaped plate, which is perforated and engaged through a registration sleeve, the registration sleeve being coaxially engaged by the drive shaft. The alignment of the shafts prevents the components of the venetian blind structure from moving unnecessarily with respect to each other, thereby reducing the chance of breaking these components.

Description

Description: A venetian blind structure, a double glazing unit and a method of assembling a venetian blind structure Field of the invention The present invention relates to a venetian blind structure for a sealed double glazing unit, and more particularly to an alignment member for a drive shaft of a venetian blind structure. Background of the Invention Double glazing is known to be very effective for efficient insulation. This is because the two glass panels confine a layer of air between them. Of course, the double glazing unit needs to be completely sealed, otherwise its special insulating properties would be lost. Venetian blinds are often used with windowpane structures, each of which has a first state that allows most of the light to pass through the windowpane and a second state that can block most of the light. It can be in any position between the two, and is relatively good in appearance and inexpensive. It is known in the art to incorporate a venetian blind structure into a double glazing unit, where the slats of the venetian blind are placed between two glass panels. In addition, the slats allow a layer of air to exist between the glass panels, so that the glazing unit, if properly sealed, does not lose its insulating properties. One of the main advantages of using this structure is that both the slat and the glazing form a unitary structure, which simplifies the handling of the structure. U.S. Pat. No. 3,702,040 issued to Fernand ROY in 1972 (hereinafter the '040 patent) describes a typical venetian blind structure for a hermetically sealed double glazing unit. Show. The glazing unit 1 is arranged on the axis in a pair of peripheral frames 3 and 4 that separate the glass panel 2 in a parallel state, and is engaged with the slats 9 in a parallel state. It comprises a plurality of stud shafts 10 and 11 to be supported. On one side of the glazing unit inside the frame, the diameter of the stud shaft is enlarged and has an outwardly projecting pin 20, which is in a complementary opening 21 inside the extended vertical actuator bar 22. Is inserted into. As the actuator bar 22 is raised and lowered, the actuator bar 22 will rotate the pin 20 which will cause the stud shafts 10 and 11 and the slat 9 to reciprocate. This opens the user at a desired distance from the desired condition, i.e., partially overlapping and closed, with the venetian blind structure blocking most of the light, and the venetian blind structure opening the venetian blind structure. The slats 9 can be placed in any state between the parts being permeable. The outer gear 42 allows the user to raise and lower the actuator bar, thus simultaneously turning the slats to the desired angle. The structure has three main problems. The first problem is that the control mechanism, for example, the gear 42 of the '040 patent, is located outside the glazing unit. Therefore, there is a need for mounting space around the window, e.g., a hole fitted into the wall adjacent the window for the casing of the gear. In order to accommodate such glazing and venetian blind assemblies, conventional glazing openings need to be modified, which is undesirable because it significantly complicates the installation of the assembly. A second problem is that it is difficult, if not impossible, to completely seal the glazing unit with moving parts that couple the control mechanism to the actuation mechanism. The double glazing unit therefore loses part of its efficiency due to leakage in the adiabatic state. A third problem relates to the fact that once the glazing unit is sealed and mounted, it is very difficult to access the venetian blind structure. However, it is a problem that arises only when it is necessary to reach into the venetian blind structure. Some parts, including moving parts, are fragile and in the art these moving parts are not securely mounted. Indeed, the drive shaft connecting the power means (the manually operated gears 40-42 in the '040 patent) to the actuation means (actuator bar 22 in the' 040 patent) consists of two moving parts: a power means and an actuation means. Thus, since the two end portions are supported, the engagement state with the operating means is easily released. If there is a problem with the venetian blind structure, it is very costly to repair it. Purpose of the invention The main object of the present invention is to provide a venetian blind incorporated in a sealed double glazing unit, the control mechanism of which is arranged inside the frame of the glazing structure so as to realize an integrated unit of standard shape.

FIG. 2 is an elevational view of the area defined by line 2 of FIG. FIG. 3 is a sectional view taken along line 3-3 in FIG. FIG. 4 is a sectional view taken along line 4-4 in FIG. FIG. 5 is a cross-sectional view taken along line 5-5 of FIG. FIG. 6 is a cross-sectional view of two slat members, showing a common swivel relationship between the members. FIG. 7 is an exploded view of the frame structure of the sealed double glazing unit. FIG. 8 is a partially exploded perspective view of the actuator bar and the idler wheel of the present invention, and shows an enlarged size. Detailed description of the embodiment FIG. 1 shows a double glazing unit 10 incorporating a venetian blind structure 12. The glazing unit 10 comprises two spaced glass panels 14, 16 (FIGS. 3 and 4) and a rectangular glazing frame 18 (FIGS. 1 and 7). FIGS. 1 and 7 show four extended peripheral groove members 20 in which the glazing frame is alternately joined by four L-shaped corner members 22 slidably engaging the inner groove 24 of the peripheral groove member 20. (20a to 20d). The corner members 22 each define a pair of legs 26, which are integrally attached to a wider abutment plate 28. The male leg 26 thus engages the female inner groove 24 of the groove member 20 and the groove member 20 abuts against the abutment plate 28, providing a continuous closed glazing frame 18. The frame 18 separates the glass panels 14, 16 by a fixed distance, and the glass panels 14, 16 are fixed on the frame 18 in a parallel state as is known in the art. Thus, the inner chamber is defined by the area defined by the glass window frame 18 and the glass panels 14,16. FIG. 3 shows that the cross-section of each peripheral groove member comprises a pair of longitudinally outwardly extending webs 30, each having an upwardly extending flange 32 and a downwardly extending and inwardly extending lip 34. Is shown. The upward flange 32 is longitudinally grooved on the inner surface 36 such that the peripheral groove members 20 are present on the outer narrow sides on the surface 38, such that the grooved surfaces 36, 38 face each other. FIG. 1 shows that the venetian blind structure 12 comprises a plurality of known louver members or slat members 40 which are arranged in the interior chamber of the glazing unit 10 and are equidistantly and horizontally arranged. Show. As shown in FIG. 6, the slat members 40 are first generally vertical, slightly overlapping each other to form a generally uniform vertical surface that can substantially completely block light rays through the glass window. From the position (indicated by the solid line), it is possible to pivot to a second, substantially horizontal position (indicated by the dashed line) which allows the light passing through the glazing unit 10 to pass almost completely. Each slat member 40 has, at its upper and lower ends, an abutment member 42 capable of connecting small end surfaces to each other. It is preferable to be able to hook each other using the contact member 42 adjacent to the lower side. The slat member 40 has first and second tips and at least one pivot shaft (not shown) at a first tip that is coaxial with the pivot axis. When the slat member is horizontal, the slat member 40 also has a second pivot shaft at a second tip, as shown in FIGS. Aligned in the direction. FIG. 3 shows that the venetian blind structure 12 further comprises a groove member 44 similar, if not identical, to the peripheral groove member 20. In effect, the cross-section of the support channel member 44 comprises a pair of longitudinally outwardly extending webs 46, each of which has a groove at the inner surface 50 so as to face the grooved outer narrow side surface 52 of the support channel member 44. And a lip 54 extending downwardly and inwardly. An inner groove 56 is arranged inside the support groove member 44. These cross sections are identical because both the support groove member 44 and the peripheral groove member 20 are formed in exactly the same manner, but are each cut to different desired lengths. This significantly reduces manufacturing costs by using one design instead of two for the two different parts of the glazing unit and venetian blind assembly. The support groove member 44 extends over the entire width of the inner chamber of the window glass unit 10 and is arranged in parallel with and spaced apart from the upper peripheral groove member 20a of the window glass frame 18 in parallel. As shown in FIG. 3, the extension strip 57 resiliently engages the lip 54 of the support channel member 44, and a short extended central downwardly extending flange 59 projects therefrom. Top slat member 40 abuts flange 59 and slightly overlaps flange 59. FIGS. 1-5 and FIGS. 7, 8 show that the venetian blind structure 12 ultimately comprises power means 58, actuation means 60 and alignment means 62. The power means 58 is a small reversible electric motor 63 and is preferably connected to a power supply (not shown) by a power supply cable 64. The power means 58 can be operated remotely or by a switch. Further, the power means 58 has a small output shaft 66 driven by the electric motor 63. The shaft 66 is inserted into a complementary coaxial hole 68 at a first end 70 a of the drive shaft 70 and is fixed using a pair of set screws 72, and the shafts 66 and 70 are provided by the motor 63. Try to share the same rotational movement. The drive shaft 70 has a second end 70b opposite the first end 70a. The motor 63 is mounted on a support 74 supported on the support groove member 44, fixed by bolts 76, and fixedly holds the motor 63 on the support groove member 44. The actuation means 60 comprises a known system as described in the '040 patent in the background of the invention. One rail member 78a, 78b (FIG. 7) is attached to each of the side peripheral groove members 20c, 20d. In effect, the rail members 78a, 78b comprise an outer flange 79 (FIG. 4) adapted to engage the lip 34 in a resilient engagement. The rail members 78a, 78b span the full height of the inner chamber of the glazing unit 10 and are provided with shoulder members 80a, 80b (FIG. 7) for supporting the support groove members 44, so that at both ends thereof. The support groove member 44 is supported. Each rail member 78a, 78b, such as the rail member 78a shown in FIGS. 4 and 5, includes a pair of rails 82 having a flat surface 83 tangentially engaged by a plurality of idler wheels 84. The operating means 60 is disposed on one rail member, that is, the rail member 78a, is movable between the rails 82, has substantially the same length as the rail member 78a, and has a peripheral groove member 20d and a cover plate 89 ( (FIG. 3). Actuator bar 88 has a plurality of spaced-apart outwardly directed openings 90 (FIG. 8) on both ends thereof, openings 90 are precisely dimensioned and have cutouts in radial grooves 91 of idler wheel 84. And the thickness of the actuator bar 88 is equal to or slightly smaller than the width of the radial groove 91 so that the groove 91 of the idler wheel 84 captures the actuator bar 88. In use, the idler wheel 84 is positioned between the rail 82 and the actuator bar 88, which engage in rolling and move along the rail member 78a as they move linearly upward or downward. Induce 88 movement. FIGS. 5 and 8 show that the actuator bar 88 has a plurality of equally spaced lateral openings 92 in its intermediate portion. One such lateral opening 92 corresponds to each slat member 40. A vehicle couples the opening 92 to the slat member 40 and imparts a pivoting movement to the slat member 40 as the actuator bar moves linearly. As shown in FIG. 5, the vehicle is engaged with a complementary gear 96 which is integrally and coaxially secured to the first pivot shaft of the corresponding slat member 40. An integrated gear cutting shelf 94 cut-out portion inside 92. Thus, as the actuator bar 88 moves linearly, the gear rack 94 imparts rotational movement to the gear 96, thereby causing the slat member 40 to pivot. The length of the opening 92 (and the hob 94) is precisely sized and allows the slat member to pivot from a first vertical position to a second horizontal position. The slat member 40 is held at a second end by a second pivot shaft, and pivotally engages a support member (not shown) of the rail member 78b. In addition, the actuator bar 88 has a wide lateral groove 98 (FIG. 5) at its upper end. As shown in FIGS. 3 and 4, the positioning means 62 includes a positioning member 100, a positioning sleeve 102, and a sealing collar 104. The alignment member 100 is a generally flat, L-shaped plate with a first leg 106 and a second leg 108 (FIG. 7). The male first leg 106 is precisely sized and engages with the groove 56 at the female end 110 of the support groove member 44, and the bolt 76 holding the motor support 74 is mounted on the upper side of the groove member 44. It is secured by passing through the surface and the first leg 106. The second leg 108 is securely fixed (eg, using bolts 111) to the rail member 78a, is further drilled, is threaded in the hole, and the alignment sleeve 102 is engaged therethrough. The drive shaft 70, near its second end 70b, axially engages the alignment sleeve 102 and can rotate freely with little or no radial movement. Drive shaft 70 includes a radial flange 112 at a second end 70b and abuts a corresponding shoulder 114 on alignment sleeve 102 (FIG. 4). The sealing collar 104 abuts the alignment sleeve 102 in the axial direction and is secured by a set screw 116 to prevent the alignment sleeve 102 from loosening and disengaging from the alignment member 100. The end of the drive shaft 70 opposite the motor 63 is flat and has a small eccentric rotatable stud 118 projecting therefrom. Stud 118 engages groove 98 in actuator bar 88. In this way, the positioning means 62 will not move and the drive shaft 70 will be reliably supported by the positioning means 62 in order to realize reliable support. The alignment member 100 and the alignment sleeve 102 prevent the drive shaft 70 from moving in any radial direction, and further, the collar 104 and the alignment sleeve 102 abut, and the radial flange 112 and the shoulder 114 abut. This prevents the drive shaft 70 from moving in any radial direction. Thus, the drive shaft 70 will be immobile in all directions except for on-axis rotation. In addition, since the actuator bar 88 is also guided into the rail member 78a and does not move unnecessarily, the movable parts of the venetian blind structure 12 similarly cannot deviate from the range of the position where they are given. Absent. Preventing the drive shaft 70 from moving radially by the alignment means 62 is an important advantage of the present invention. While it is very important that the shaft 70 remains normally aligned, it is not possible to repair a defective Venetian blind structure once the glazing unit 10 is sealed and embedded in the wall. This is because it is a very time-consuming and costly operation. Proper positioning of the individual moving parts is very important, since the moving parts are fragile parts. This is the reason why the drive shaft 70 is relatively resistant and is positioned via the highly accurate positioning means 62. Of course, the fit between the alignment sleeve 102 and the drive shaft 70 is probably not perfect, ie there will be a small radial play between the two, but the shaft 70 has a high rotational speed This play will not significantly impede the movement of the shaft 70, as it is, and is not designed to apply a large amount of torque. In use, when the motor 63 is driven, the drive shaft 70 rotates via the output shaft 66, and the stud 118 rotates around the rotation axis of the drive shaft 70. Stud 118 can roll or slide freely laterally within groove 98, while its upward or downward movement will impart the same amount of movement to actuator bar 88. . Thus, as the drive shaft 70 rotates, the actuator bar 88 moves up and down, thereby causing the slat member 40 to pivot. Since there are no other movable parts in the inner room of the window glass unit 10, the window glass is completely sealed. A suitable sealing material 120 (FIGS. 3-5) is used around the entire glazing unit 10 and is mounted on the peripheral groove member 20, as is known in the art. Once dried, it will be held in place by the teeth because the sealing material 120 will be embedded between the teeth 36 and 38 of the upper flange 32 and the narrow sides of the peripheral groove member 20 and will keep the windowpane unit 10 in a secure state. Will be sealed. In order to incorporate the venetian blind structure 12 inside the glazing unit 10, a more precise procedure must be carried out step by step. Assembly of the venetian blind structure must take place before assembly of the glazing unit. The method generally comprises the following steps. a) attaching the actuation means along at least one peripheral groove member; b) pivotally engaging the actuating means with the slat member pivot shaft; c) bringing the second leg of the alignment member into contact with the actuating means and fixing it there. d) engaging the drive shaft with the actuating means via the hole in the second leg of the alignment member. e) A step of axially engaging the alignment sleeve around the drive shaft. f) securing the alignment sleeve in the bore of the second leg of the alignment member, thereby axially disposing the drive shaft with respect to the alignment member and the actuating means. g) engaging and securing the first leg of the alignment member in the support groove member. h) connecting the power means to the drive shaft. i) A step of fixing the power means to the support groove member. Engaging the sealing collar around the drive shaft, abutting the sealing collar on the alignment sleeve, and securely securing the sealing collar to the drive shaft, steps f) and g). While a conventional rectangular glazing unit is disclosed in the present invention, it will be appreciated that any other shape is possible. For example, a hexagonal windowpane unit may be used so that the windowpane frame comprises six peripheral groove members and the same number of corner members, so that an obtuse angle is formed instead of an L-shape. In the case of providing two actuator bars that are coupled to each other, one carries the other according to the movement of the drive shaft, and the radius of the gear or the pitch between the gear and the shelf is changed on the actuator bar to be carried, so that two actuator bars are provided. The difference in travel resulting from the angle between the bars would have to be compensated. Also, by providing a desired angle on the side surface of the groove member to which the panel is fixed, a non-parallel window glass panel could be realized. Further, within the scope of the present invention, a vertical slat member which requires only one support shaft at its upper end in order for the slat member to keep its vertical position down due to the weight of the slat member itself Can be provided. The actuator bar will of course be horizontal above the inner chamber of the glazing unit 10. It will also be appreciated that the actuation means may be of another type different from the described characteristics. For example, the actuator bar may be a long actuator rod, and the shelf and gear assembly may be a small metal rod eccentrically coupled to the actuator rod.
