Abstract
Description
Technical Field
[0001] The present invention relates to a window structure capable of opening and closing an opening of a building by moving at least one movable window panel among two or more window panels made of multilayer glass.
Background Art
[0002] In recent years, from the perspective of aiming for so-called carbon neutrality, which makes the overall emission of greenhouse gases zero, efforts to reduce greenhouse gases have also been progressing in the construction industry. As a result, high heat insulation performance has been required for newly constructed buildings, and the construction of heat insulating materials such as glass wool and rock wool has been expanding for ceilings, outer walls, floors, etc. Furthermore, heat insulation is required for openings such as windows, and the adoption of multilayer glass having a hollow layer between glasses has also been increasing.
[0003] Multilayer glass refers to a glass structure formed by arranging two or more glass plates in parallel at a certain interval and sealing the interval with a frame. This multilayer glass prevents heat transfer by enclosing dry air or argon gas, which has a lower thermal conductivity than air, in the hollow layer between the glass plates, or by making it vacuum, thereby enhancing the heat insulation performance. In this multilayer glass, in recent years, a unitized structure in which three or more glasses are stacked with intervals between them has been particularly widespread from the perspective of further improving the heat insulation performance.
[0004] Incidentally, when applying such double-glazed glass to window panels in building structures, its thickness increases compared to single-pane glass. As a result, applying double-glazed glass to window panels in building structures increases the visual and physical volume, inevitably making the window structure itself larger. Consequently, while window structures using double-glazed glass are superior in terms of thermal insulation, they are inferior in terms of visual design. In particular, when double-glazed glass consists of three or four panes of glass, the thickness of the frame itself, which fixes these panes of glass and maintains airtightness in the air gap, also increases accordingly, making the window panel frame visually more prominent.
[0005] Therefore, when applying such double-glazed glass, which has superior thermal insulation performance, to window panels of building structures, it was necessary to minimize the visual and physical sense of volume, at least when the window is closed, and to create a window structure that is visually superior in terms of design.
[0006] Conventionally, Patent Document 1 has proposed an opening and closing device such that the window panels are flush with each other when in the closed position. However, there was a need for a window structure that was smooth and easy to operate when opening and closing the window panels. [Prior art documents] [Patent Documents]
[0007] [Patent Document 1] Japanese Patent Publication No. 2005-256411 [Overview of the Initiative] [Problems that the invention aims to solve]
[0008] Therefore, the present invention was devised in view of the above-mentioned problems, and its objective is to provide a window structure that minimizes the visual and physical sense of volume, at least when the window is in the closed position, is visually superior in terms of design, and is also smooth and easy to operate when opening and closing the window panel. [Means for solving the problem]
[0009] The window structure according to the first invention is a window structure in which an opening in a building can be opened and closed by moving at least one movable window panel from two or more window panels made of double-glazed glass, wherein the movable window panel is made of other Window panel and The window panel is characterized by its ability to move from an open position in parallel to another window panel, making a U-turn via guide rails formed on the upper and lower frames of the opening, respectively, to a closed position where it is flush with the other window panel.
[0010] The window structure according to the second invention is characterized in that, in the first invention, the other window panels are fixed in a way that prevents them from moving.
[0011] The window structure according to the third invention is, in the first or second invention, the abutting surfaces of the movable window panel and the other window panel in the closed position The elastic body It is characterized by being able to be sealed by applying pressure through an intermediary. [Effects of the Invention]
[0012] According to the present invention, which has the above-described configuration, when the window panels are in the closed position, they can be arranged so that they are flush with each other in a straight line without any misalignment.
[0013] In particular, since window panels have a double-glazed structure, they are thicker than single-pane glass, which inevitably increases the visual and physical sense of volume. In contrast, according to the present invention, when the window is in the closed position, the window panels can be arranged so that they are flush with each other, as described above, thereby minimizing the visual and physical sense of volume and making it possible to create a window structure with superior visual design.
[0014] Furthermore, according to the present invention, by configuring the trajectory to make a U-turn from the left end toward the closed position via guide rails, the window panel itself can be moved to the closed position by making a U-turn along these guide rails. As a result, the window panel can be moved from the open position to the closed position very smoothly, and the operability of the opening and closing operation is also excellent.

Embodiments for Carrying Out the Invention
[0016] Hereinafter, an example of the window structure 100 as an embodiment of the present invention will be described in detail with reference to the drawings.
[0017] Note that the configurations in each figure are schematically described for the purpose of explanation, and for example, the sizes of each configuration and the size ratios for each configuration may be different from those in the figures.
[0018] Referring to FIG. 1, an example of the window structure 100 in the present embodiment will be described. The window structure 100 is used for windows of building structures such as houses, buildings, factories, warehouses, etc.
[0019] The window structure 100 comprises a pair of upper and lower frames 4 and 5, and a pair of left and right vertical frames 6 and 7, which are fixed to the building frame that constitutes the opening 101. The window structure 100 also comprises a window panel 1 located on the left vertical frame 6 side (hereinafter referred to as left X1) when in the closed position, and a window panel 2 located on the right vertical frame 7 side (hereinafter referred to as right X2) when in the closed position, within the frame consisting of the upper frame 4, lower frame 5, left vertical frame 6 and right vertical frame 7. In this window structure 100, the exterior side of the building is referred to as the exterior X3 (depth direction in Figure 1), and the interior side of the building is referred to as the interior X4 (front direction in Figure 1).
[0020] Figure 2 is a plan view of the upper frame 4, and Figure 3 is a cross-sectional view thereof AA'. The upper frame 4 is made of a metal material with a long, roughly U-shaped cross-section. Four through-hole-shaped guide rails 42, 43, 44, and 45 are formed in the web portion 41 of the upper frame 4.
[0021] Of these, the right ends 42a and 43a of the guide rails 42 and 43, which face right X2, are located approximately midway between the left vertical frame 6 and the right vertical frame 7. The guide rails 42 and 43 extend linearly from these right ends 42a and 43a toward left X1, and then curve inward toward left ends 42b and 43b in a roughly circular arc toward X4. Then, from left ends 42b and 43b, the guide rails 42 and 43 curve further inward toward their ends 42c and 43c in a roughly circular arc toward inward X4 and right X2. In other words, the guide rails 42 and 43 trace a trajectory that makes a U-turn toward the ends 42c and 43c via left ends 42b and 43b. The guide rails 42 and 43, which have such a trajectory, are arranged to be equally spaced and parallel to each other.
[0022] Guide rails 44 and 45 have their right ends 44a and 45a, which are oriented towards the right X2, located X2 to the right of the right ends 42a and 43a of guide rails 42 and 43. Furthermore, the right ends 44a and 45a of guide rails 44 and 45 are located X4 inward of the right ends 42a and 43a of guide rails 42 and 43. Guide rails 44 and 45 extend linearly from these right ends 44a and 45a towards the left X1, and then curve inward towards the left ends 44b and 45b in a roughly circular arc X4. Then, from the left ends 44b and 45b, guide rails 44 and 45 curve further in a roughly circular arc toward their ends 44c and 45c, oriented inward X4 and towards the right X2. In other words, guide rails 44 and 45 trace a trajectory that makes a U-turn toward the ends 44c and 45c via the left ends 44b and 45b. Guide rails 44 and 45, which consist of such tracks, are arranged at equal intervals and parallel to each other. Furthermore, the ends 44c and 45c of guide rails 44 and 45 are located to the right X2 and inward X4 from the ends 42c and 43c of guide rails 42 and 43.
[0023] These two sets of guide rails 42 and 43, and guide rails 44 and 45, are composed of independent tracks that do not intersect with each other. As will be described later, all of these guide rails 42 to 45 are provided to guide the window panel 1.
[0024] Figure 4 is a plan view of the lower frame 5, and Figure 5 is a cross-sectional view of its BB'. The lower frame 5 is made of a metal material with a long, roughly U-shaped cross-section. A protruding ridge 57 is formed on the web portion 51 of the lower frame 5, projecting upward. Two groove-shaped guide rails 52 and 54 are formed X4 inside this protruding ridge 57. Further inside X4 from this guide rail 54, a flange 58 is formed.
[0025] Of these, the right end 52a of the guide rail 52, which faces right X2, is located approximately midway between the left vertical frame 6 and the right vertical frame 7. The guide rail 52 extends linearly from this right end 52a toward left X1, and then curves toward left end 52b in an approximately circular arc toward inward X4. Then, from left end 52b, the guide rail 52 curves further toward its end 52c in an approximately circular arc, oriented toward inward X4 and right X2. The track of this guide rail 52 is designed to be vertically aligned with the tracks of the guide rails 42 and 43 provided on the upper frame 4. In other words, the guide rail 52 traces a U-turn track toward end 52c via left end 52b.
[0026] The right end 54a of guide rail 54, facing to the right X2, is located X2 to the right of the right end 52a of guide rail 52. Moreover, the right end 54a of guide rail 54 is located X4 inward from the right end 52a of guide rail 52. Guide rail 54 extends linearly from this right end 54a toward the left X1, and then curves inward towards the left end 54b in a roughly circular arc X4. Then, from the left end 54b, guide rail 54 curves further toward its end 54c in a roughly circular arc, oriented inward X4 and toward the right X2. In other words, guide rail 54 traces a trajectory that makes a U-turn toward its end 54c via its left end 54b. The end 54c of guide rail 54 is located X2 to the right and X4 inward from the end 52c of guide rail 52.
[0027] These two sets of guide rails 52 and guide rail 54 are composed of independent tracks that do not intersect with each other. As will be described later, these guide rails 42-45, 52, and 54 are all provided to guide the window panel 1.
[0028] Furthermore, the track of the guide rail 52 provided on the lower frame 5 is designed to be aligned with the tracks of the guide rails 42 and 43 provided on the upper frame 4 in the vertical direction, and similarly, the track of the guide rail 54 provided on the lower frame 5 is designed to be aligned with the tracks of the guide rails 44 and 45 provided on the upper frame 4 in the vertical direction.
[0029] Figure 6 is a cross-sectional view of CC' in Figure 1. As shown in Figure 6, the left vertical frame 6 is made of a metal material with a long vertical section and a roughly U-shaped cross-section. The left vertical frame 6 has a U-shaped pocket 61 formed in its cross-section to secure the movement area of the window panel 1 that is opened and closed. The right vertical frame 7, which is provided opposite the left vertical frame 6 between the left side X1 and the right side X2, does not need to have such a pocket formed in it, so it is sufficient if it is at least flat.
[0030] Next, the configuration of window panels 1 and 2 will be explained. Window panels 1 and 2 are made of so-called double-glazed glass, which is formed by arranging two or more glass plates parallel to each other at a constant distance and sealing the gap with a frame. Figure 7 is a cross-sectional view CC' of window panel 1 shown in Figure 1, which shows the cross-sectional configuration in the planar direction.
[0031] The window panel 1 consists of four glass plates 11a, 11b, 11c, and 11d arranged parallel to each other at regular intervals. A hollow layer 12a is formed between glass plates 11a and 11b, a hollow layer 12b is formed between glass plates 11b and 11c, and a hollow layer 12c is formed between glass plates 11c and 11d. By sealing argon gas in each of these hollow layers 12a to 12c or creating a vacuum, heat transfer can be prevented and the thermal insulation performance can be improved.
[0032] Furthermore, the left ends of the glass plates 11a to 11d are sealed and fixed to each other, thereby creating a closed space in the hollow layers 12a to 12c that is shielded from the outside. Specifically, at the left end X1 of the window panel 1, a spacer 13a is sandwiched between the glass plates 11a and 11b, and an elastic material 14a such as rubber or resin is sandwiched to the left of X1. Similarly, a spacer 13b is sandwiched between the glass plates 11b and 11c, and an elastic material 14b such as rubber or resin is sandwiched to the left of X1. Similarly, a spacer 13c is sandwiched between the glass plates 11c and 11d, and an elastic material 14c such as rubber or resin is sandwiched to the left of X1. At the right end X2 of the window panel 1, a spacer 13a is sandwiched between the glass plates 11a and 11b. Similarly, a spacer 13b is sandwiched between glass plates 11b and 11c. Similarly, a spacer 13c is sandwiched between glass plates 11c and 11d. At the right end X2 of the window panel 1, an elastic body 14d made of rubber, resin, or the like is provided on the right side X2 of these spacers 13a to 13c.
[0033] The spacers 13 allow the distance between the glass plates 11 to be kept constant, and the elastic body 14 helps to mitigate impacts when the glass plates come into contact with other components.
[0034] The window panel 1 is further provided with a window vertical frame 16 at its left end X1. This window vertical frame 16 is made of resin or metal and has a long, vertically elongated, substantially U-shaped cross-section. This window vertical frame 16 has flanges 16b formed at both ends of a web 16a, and a laminate consisting of glass plates 11a to 11d is sandwiched and fixed between the two flanges 16b. The web 16a of the window vertical frame 16 may have screw holes formed in it as needed, and may also be provided with fastening members such as bolts.
[0035] The right-side X2 end of window panel 1 is located at a point where it comes into contact with window panel 2, which is flush with the window panel 2 when it is closed. To enhance the seal and mitigate the impact between them, the window vertical frame 16 is not provided, and the elastic body 14d is left exposed. When the window panel is closed, the elastic body 14d provided at the right-side X2 end of window panel 1 and the elastic body 14d provided at the left-side X1 end of window panel 2 come into contact with each other and adhere tightly, shielding the outside from the inside of the building, while these elastic bodies 14 also act as a buffer.
[0036] Incidentally, the configuration of window panel 2 is the same as that of window panel 1, consisting of a double-glazed structure, so the explanation below will be omitted. However, window panel 2 has a symmetrical configuration compared to window panel 1, with a window vertical frame 16 provided at the right end X2 of window panel 2, and the elastic body 14d exposed at the left end X1 of window panel 2. This allows the right end X2 of window panel 1 and the left end X1 of window panel 2 to be in contact with each other via the elastic body 14 and to be tightly fixed.
[0037] Figure 8 is a cross-sectional view DD' of window panel 1 shown in Figure 1, which essentially shows the cross-sectional configuration in the vertical direction.
[0038] Similarly, in the vertical direction, spacers 13e to 13g are sandwiched between the upper ends of the glass plates 11a to 11d, and elastic bodies 14e to 14g are sandwiched above them. Similarly, spacers 13e to 13g are sandwiched between the lower ends of the glass plates 11a to 11d, and elastic bodies 14e to 14g are sandwiched below them.
[0039] At the lower end of the window panel 1, a caster 22 and a ball body 23 are further provided, attached to the lower end of a screw 21. The ball body 23, fitted into the caster 22, is capable of moving freely over 360°. The screw 21 attached to the caster 22 may be screwed into a spacer 13 or an elastic body 14 provided at its lower end. Alternatively, the lower end of the window panel 1 may have a frame material (not shown) with a roughly U-shaped cross-section fitted into it, and the screw 21 may be screwed into this frame material (not shown).
[0040] The upper end of the window panel 1 is provided with shafts 24a and 24b, and rollers 25a and 25b that are rotatably mounted around these shafts 24a and 24b. The lower ends of the shafts 24a and 24b may have threads formed on them and be screwed into a spacer 13 or an elastic body 14. Alternatively, the upper end of the window panel 1 may be fitted with a frame material (not shown) with a roughly U-shaped cross-section, and the shafts 24a and 24b may be screwed into this frame material (not shown). Note that the configuration of rollers 25a and 25b is not essential and may be omitted.
[0041] Figure 9(a) shows a plan view of the window panel 1 as seen from above. On the upper surface of the window panel 1, shafts 24a-1 and 24b-1 are provided on the left side X1, and shafts 24a-2 and 24b-2 are provided on the right side X2. The pair of shafts 24a-2 and 24b-2 are provided on the inside X4 from the pair of shafts 24a-1 and 24b-1.
[0042] Figure 9(b) shows a bottom view of window panel 1 as seen from above. On the bottom surface of window panel 1, caster 22-1 and ball body 23-1 are provided on the left side X1, and caster 22-2 and ball body 23-2 are provided on the right side X2. Caster 22-2 and ball body 23-2 are located on the inside X4 compared to caster 22-1 and ball body 23-1.
[0043] It is assumed, but not limited to, that the planar arrangement of caster 22-1 and ball body 23-1 corresponds to shaft bodies 24a-1 and 24b-1, and that the planar arrangement of caster 22-2 and ball body 23-2 corresponds to shaft bodies 24a-2 and 24b-2.
[0044] The configuration of the upper and lower ends of window panel 2 may be the same as that of window panel 1. If window panel 2 is fixed and immovable, and only window panel 1 is configured to be openable and closable, the configuration of casters 22, ball body 23, shaft body 24, and rollers 25 may be omitted for window panel 2.
[0045] Next, the opening and closing operation of the window structure 100 to which the present invention is applied will be described.
[0046] Figure 10(a) is a plan cross-sectional view of the upper end of window panels 1 and 2 in the open position, and Figure 10(b) is a plan cross-sectional view of the lower end of window panels 1 and 2 in the same open position. In this open position, window panels 1 and 2 are arranged in parallel with each other.
[0047] The rollers 25a and 25b, which are rotatably mounted on the shafts 24a-1 and 24b-1 of the window panel 1, are fitted into the guide rails 42 and 43. The rollers 25a and 25b, which are rotatably mounted on the shafts 24a-1 and 24b-1 of the window panel 1, are fitted into the guide rails 42 and 43. The rollers 25a and 25b, which are rotatably mounted on the shafts 24a-2 and 24b-2, are fitted into the guide rails 44 and 45.
[0048] Figure 11 shows the state in which the rollers 25a and 25b, which are provided on the shafts 24a-1 and 24b-1 of the window panel 1, are fitted into the guide rails 42 and 43. As the rollers 25a and 25b rotate along the guide rails 42 and 43, the window panel 1 can move freely to the left X1 or to the right X2.
[0049] Furthermore, the ball body 23-1 fitted into the caster 22-1 provided at the lower end of the window panel 1 is fitted onto a groove-shaped guide rail 52 and is guided via the guide rail 52. Similarly, the ball body 23-2 fitted into the caster 22-2 provided at the lower end of the window panel 1 is fitted onto a groove-shaped guide rail 54 and is guided via the guide rail 54.
[0050] Figure 11 shows the state in which the ball body 23-1, which is fitted into the caster 22-1 provided at the lower end of the window panel 1, is fitted into the groove-shaped guide rail 52. As the ball body 23-1 rotates along the guide rail 52, the window panel 1 can move freely to the left X1 or to the right X2. Similarly, as the ball body 23-2 rotates along the guide rail 54, the window panel 1 can move freely to the left X1 or to the right X2.
[0051] To transition from the open position to the closed position, window panel 1 is moved towards the left X1 as shown in Figure 12(a). During this time, window panel 2 remains stationary without being moved. Window panel 1 moves to the left X1 as the rollers 25a and 25b on shafts 24a-1 and 24b-1 are guided by guide rails 42 and 43, and the rollers 25a and 25b on shafts 24a-2 and 24b-2 are guided by guide rails 44 and 45. Similarly, window panel 1 moves to the left X1 as ball body 23-1 is guided by guide rail 52, and ball body 23-2 is guided by guide rail 54.
[0052] When the window panel 1 is moved to the left side X1 in this manner, as shown in Figure 12(b), the rollers 25a and 25b on the shafts 24a-1 and 24b-1 reach the left ends 42b and 43b of the guide rails 42 and 43, and the rollers 25a and 25b on the shafts 24a-2 and 24b-2 reach the left ends 44b and 45b of the guide rails 44 and 45. In addition, the ball body 23-1 reaches the left end 52b of the guide rail 52, and the ball body 23-2 reaches the left end 54b of the guide rail 54.
[0053] Next, window panel 1 is moved to the right side X2. As a result, as shown in Figure 13(a), the rollers 25a and 25b on shafts 24a-1 and 24b-1 reach the ends 42c and 43c of guide rails 42 and 43, and the rollers 25a and 25b on shafts 24a-2 and 24b-2 reach the ends 44c and 45c of guide rails 44 and 45. Also, as shown in Figure 13(b), ball body 23-1 reaches the end 52c of guide rail 52, and ball body 23-2 reaches the end 54c of guide rail 54. As a result, window panel 1 moves to the closed position in relation to window panel 2.
[0054] The positions of terminals 42c, 43c, 44c, 45c and terminals 52c, 54c are designed so that when window panel 1 is in the closed position, it is flush with window panel 2. This allows window panel 1 and window panel 2 to be aligned in a straight line from the outside X3 to the inside X4 without any misalignment when in the closed position.
[0055] In particular, since window panels 1 and 2 have a double-glazed structure, their thickness is greater compared to single-pane glass, inevitably increasing the visual and physical sense of volume. In contrast, according to the present invention, when the window is in the closed position, as described above, window panels 1 and 2 can be arranged to be flush with each other, minimizing the visual and physical sense of volume and making it possible to create a window structure with superior visual design.
[0056] Furthermore, according to the present invention, by configuring the trajectory to make a U-turn from the left end toward the closed position via guide rails 42-45, 52, and 54, the window panel 1 itself can be moved to the closed position by making a U-turn along these guide rails 42-45, 52, and 54. As a result, the window panel 1 can be moved from the open position to the closed position very smoothly, and the operability of the opening and closing operation is also excellent.
[0057] Furthermore, by providing a door pocket 61 in the left vertical frame 6, the movable range of the window panel 1 is secured, making it possible to make a U-turn along the guide rail of the window panel 1.
[0058] In this invention, when the window panel 1 and the window panel 2 are in the closed position, they can be sealed by pressing them together via an elastic body 14d provided in place of a window frame. As for the form in which the elastic bodies 14d are pressed together, for example, as shown in Figures 14(a) and (b), one elastic body 14d may be formed in a concave shape and the other in a convex shape, so that the elastic bodies 14d fit together on a concave and convex surface. The shape of this concave and convex surface can be anything, and as shown in Figure 14(a), it may be an angular shape in cross-section, or as shown in Figure 14(b), it may be a rounded, streamlined shape in cross-section.
[0059] Furthermore, as shown in Figure 14(c), the elastic bodies 14d may be configured in a convex shape when pressed together. This allows for a tight seal between the convex elastic bodies 14d. Note that the shape of the elastic bodies is not limited to the form shown in Figure 14, and may be any shape.
[0060] Figure 15 shows another embodiment of the window structure 100' to which the present invention is applied. Figure 15(a) is a plan view of the upper frame 4 of the window structure 100', Figure 15(b) is a front view of the window structure 100', and Figure 15(c) is a plan view of the lower frame 5 of the window structure 100'.
[0061] This window structure 100' includes a window panel 1a located on the left side X1 when in the closed position, a window panel 1b located on the right side X2 when in the closed position, and a window panel 2 located midway between window panel 1a and window panel 1b. In the window structure 100', components and members identical to those in the aforementioned window structure 100 are given the same reference numerals, and their explanation below is omitted.
[0062] In this window structure 100', window panel 2 is fixed so as to be immovable, while window panels 1a and 1b are openable and closable. The opening and closing operation of window panel 1a is the same as that of window panel 1 described in window structure 100, so the following explanation will be omitted by applying the explanation of the operation of window panel 1.
[0063] The opening and closing operation of window panel 1b is identical to that of window panel 1a, except that it is exactly symmetrical to it. The guide rails 42-45, 52, and 54 for window panel 1b are also provided so as to be symmetrical to the guide rails 42-45, 52, and 54 for window panel 1a. Window panel 1b can be moved to the closed position by making a U-turn from the right end towards the closed position via the guide rails 42-45, 52, and 54. This allows window panel 1 to move from the open position to the closed position very smoothly, resulting in excellent operability in terms of opening and closing operation.
[0064] In the window structure 100', by providing a door pocket 61 in the right vertical frame 7, the movable range of the window panel 1b is secured, making it possible to make a U-turn along the guide rail of the window panel 1b. Similarly in this window structure 100', in the closed position, the window panels 1a, 1b and window panel 2 can be aligned in a single straight line from the outside X3 to the inside X4 without any misalignment. Furthermore, both window panels 1a and 1b can move extremely smoothly from the open position to the closed position, resulting in excellent operability in terms of opening and closing operations.
