Description

[Technical Field]

[0001] The present invention relates to a multiple window having a plurality of windows arranged opposite each other in an opening in a wall. [Background technology]

[0002] Patent Document 1 discloses a soundproof panel with a window, which includes a pair of exterior panels arranged opposite each other with a gap between them, a window portion formed through the pair of exterior panels, a core that is provided to surround the window portion and separates the gap between the pair of exterior panels into a window panel air space and a sound-absorbing material air space, sound-absorbing material filled in the sound-absorbing material air space, and a pair of window panels attached to both the front and back sides of the window portion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-293126 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the windows to which such soundproof panels are applied are not designed to be fitted into openings formed in partition walls that separate the interior and exterior of a room, nor are they designed to facilitate the replacement of the glass panes of the windows. In other words, the above document does not disclose any structure in which two windows, each having a glass pane, are fitted into an opening in the partition wall in an opposing arrangement, and the glass pane of the window located on the exterior side of the room can be removed from the interior side and replaced.

[0005] An object of the present invention is to provide a multiple window structure in which a plurality of windows, each having a window plate, are fitted into an opening in a wall in an opposing arrangement, and in which, for example, the window plate of the window located on the outside of the plurality of windows can be removed from the inside of the room and replaced. [Means for solving the problem]

[0006] The multiple window of the present invention has at least: a first window having a first window plate, a receiving side frame portion having a contact surface with which an end face of the first window plate contacts and a receiving portion that receives an edge portion on one side of the first window plate, and a pressing side frame portion made up of a plurality of separable rod-shaped bodies that presses the edge portion on the other side of the first window plate; a second window including a second window plate; a receiving side frame portion having a contact surface with which an end face of the second window plate contacts and a receiving portion that receives an edge portion on one side of the second window plate; and a pressing side frame portion made up of a plurality of separable rod-shaped bodies that presses the edge portion on the other side of the second window plate; are disposed opposite to each other and fitted together with the pressing side frame portions positioned on the same side, The size of the second window plate is such that it can be removed from the side where the first window is located when the pressing side frame portion of the first window and the first window plate are removed and the receiving side frame portion remains.

[0007] With the above configuration, the pressing side frame portion and the first window pane of the first window can be removed, and the second window pane can be removed and replaced from the side where the first window is located, while the receiving side frame portion remains. However, if the pressing side frames of the first and second windows were positioned on opposite sides of each other, the second window pane could be replaced independently without removing the first window. However, this hypothetical configuration has the drawback that it would be difficult to replace the second window pane if the second window is located on the atrium side.

[0008] The second window plate may be smaller than the inner surface of the receiving frame portion of the first window and may be removable from the arrangement side of the first window in a vertical position. If the second window plate can be removed from the arrangement side of the first window in this vertical position, the replacement work of the second window plate becomes easier.

[0009] Alternatively, the second window plate may be larger than or equal to the inner surface of the receiving frame portion of the first window, and may be removable from the side of the first window by passing over an inner corner of the receiving frame portion of the first window in a non-vertical position. In this way, even in a configuration in which the second window plate is larger than or equal to the inner surface of the receiving frame portion of the first window, the second window plate can be replaced by being in a non-vertical position.

[0010] The receiving frame portions of the first window and the second window may be fixed to a plate member that forms a periphery of the opening in the wall.

[0011] A decorative member may be provided on the inner surface of a portion of the plate located between the receiving frame portion of the first window and the pressing frame portion of the second window, thereby improving the aesthetic appearance of the multiple window pane.

[0012] Alternatively, the receiving frame of the first window may be fixed to a plate material that forms the periphery of the opening in the wall, and the receiving frame of the second window may be fixed to the receiving frame of the first window. In this way, the receiving frame of the first window itself can improve the aesthetic appearance of the multiple window pane without the need to attach a decorative member.

[0013] In these multiple window panes, the first window may be located on the indoor side and the second window on the outdoor side, and the receiving frame portion of the second window may protrude toward the outdoor side beyond the wall surface of the wall. [Effects of the Invention]

[0014] The present invention has the effect of facilitating replacement of window panes in a multiple window in which at least a first window and a second window are arranged opposite each other in an opening in a wall. [Brief explanation of the drawings]

[0016] (Embodiment 1) An embodiment of the present invention will now be described with reference to the accompanying drawings. The multiple window 3 of this embodiment has a structure in which a first window 1 and a second window 2 are fitted in an opening 41 in a partition wall 4 of a soundproof room in an opposing arrangement.

[0017] The first window 1 comprises a first window panel 11 made of a glass plate or the like, a frame-shaped receiving frame portion 12 that receives the first window panel 11, and a frame-shaped pressing frame portion 13 that presses the first window panel 11.

[0018] The receiving frame portion 12 has, at the corners of the inner surface of the receiving frame portion 12, a contact surface 12a against which the end face of the first window plate 11 contacts, and a receiving portion 12b that receives one side edge of the first window plate 11. The receiving frame portion 12 is fixed to plywood (board material) 14 that forms the periphery of the opening 41 of the partition wall 4 by screws that are screwed into the contact surface 12a. The plywood 14 is fixed to crosspieces 42 of the partition wall 4 by screws (not shown).

[0019] The holding side frame portion 13 is made up of a plurality of separable rod-shaped bodies. Screws (not shown) pass through each rod-shaped body and are threaded into the receiving side frame portion 12, thereby pressing the edge portion on the other side of the first window plate 11 and pressing the first window plate 11 against the receiving side frame portion 12. Furthermore, by removing the screws, the holding side frame portion 13 is separated into a plurality of rod-shaped bodies, making it possible to remove the first window plate 11.

[0020] The second window 2 comprises a second window panel 21 made of a glass plate or the like, a frame-shaped receiving frame portion 22 that receives the second window panel 21, and a frame-shaped pressing frame portion 23 that presses the second window panel 21. On the second window 2 side, an adjusting plywood 50 having a thickness similar to that of the plywood 14 is fixed to a crosspiece 42 to adjust for the second window 2 being smaller than the first window 1.

[0021] The receiving frame portion 22 has, at a corner of the inner surface of the receiving frame portion 22, a contact surface 22a against which the end face of the second window pane 21 contacts, and a receiving portion 22b that receives one side edge of the second window pane 21. The receiving frame portion 22 is fixed to a plywood (plate material) 24 that forms the periphery of the opening 41 of the partition wall 4 with screws that are driven into the contact surface 22a. This plywood 24 is fixed to the adjusting plywood 50 with screws (not shown). The receiving frame portion 22 of the second window 2 protrudes outside the room beyond the outside wall surface of the partition wall 4. The receiving frame portion 22 is fixed to the plywood 24 in advance to prevent deformation, but the present invention is not limited to such a pre-fixed structure.

[0022] The holding-side frame portion 23 is made up of a plurality of separable rod-shaped bodies. Screws (not shown) pass through each rod-shaped body and are threaded into the receiving-side frame portion 22, thereby pressing the other side edge of the second window plate 21 and pressing the second window plate 21 against the receiving-side frame portion 22. Furthermore, by removing the screws, the holding-side frame portion 23 is separated into a plurality of rod-shaped bodies, making it possible to remove the second window plate 21.

[0023] The first window 1 and the second window 2 have the pressing side frame portions 13, 23 positioned on the same side (the soundproof room side).

[0024] The size of the second window panel 21 is such that it can be removed from the side where the first window 1 is placed (the inside of the soundproof room) when the holding side frame portion 13 and the first window panel 11 of the first window 1 are removed and the receiving side frame portion 12 remains.

[0025] In this embodiment, the second window plate 21 is smaller than the size of the inner surface of the receiving-side frame portion 12 of the first window 1 and can be removed in a vertical position from the arrangement side of the first window 1. When removing the second window plate 21, as described above, the pressing-side frame portion 23 is separated into a plurality of rod-shaped bodies, so the size of the pressing-side frame portion 23 does not matter. Note that, for example, if a suction cup is attached to the surface of the second window plate 21, it is possible to remove the second window plate 21 without holding the edge with fingers.

[0026] In this way, with the multiple window pane 3, the pressing side frame portion 13 and the first window pane 11 of the first window 1 can be removed, and the second window pane 21 can be taken out and replaced from the side where the first window is located (the side inside the soundproof room) while leaving the receiving side frame portion 12. Furthermore, if the second window pane 21 can be removed in a vertical position from the side where the first window is located, the replacement work of the second window pane becomes easier.

[0027] Here, the inner surface side (arrow G in FIG. 1 ) of the portion of the plywood 24 of the second window 2 located between the receiving frame portion 12 of the first window 1 and the holding frame portion 23 of the second window 2 is not covered by the receiving frame portion 22, and the plywood 24 is exposed. This reduces the aesthetic appeal of the multiple window pane 3. Therefore, in this embodiment, a trim (e.g., 5.5 mm thick; not shown) serving as a decorative member is attached to the arrow G, thereby improving the aesthetic appearance of the multiple window pane 3. The portion of the plywood 14 exposed on the inside of the soundproof room can be covered with wallpaper attached to the partition wall 4.

[0028] The installation procedure for the multiple window pane 3 is briefly described below. First, the plywood 24, which is already attached to the receiving frame 22 of the smaller second window 2, is fixed to the adjusting plywood 50 with screws. After this, the second window pane 21 is attached and fixed with the holding frame 23. Next, the first window 1 is attached using the same procedure.

[0029] It is also possible to first fix the plywood 24 to the adjusting plywood 50 (with the second window panel 21 and holding side frame 23 not yet attached), then fix the plywood 14 of the receiving side frame 12 of the first window 1 to the crosspiece 24 (with the first window panel 11 and holding side frame 13 not yet attached), then attach the second window panel 21 to the second window 2 and fix it with the holding side frame 23, and then attach the first window panel 11 to the first window 1 and fix it with the holding side frame 13. It is also possible to change the position of the crosspiece 42 on the second window 2 side and fix the plywood 24 to this crosspiece 42 without placing the adjusting plywood 50.

[0030] FIG. 2 shows a multiple window pane 3 applied to a partition wall 4 that is thicker than the partition wall 4 shown in FIG. 1 . Compared to FIG. 1 , there are no significant differences in the structures of the first window 1 and the second window 2, but the spacing between the first window 1 and the second window 2 is wider. The inner surface of the plywood 24 of the second window 2, located between the receiving frame 12 of the first window 1 and the retaining frame 23 of the second window 2 (arrow G in FIG. 2 ), is not covered by the receiving frame 22, exposing the plywood 24. Because the spacing between the first window 1 and the second window 2 is wider as described above, the area G in FIG. 2 is larger. In this embodiment, a decorative baseboard (e.g., 5.5 mm thick; not shown) is attached to the area G to improve the aesthetic appearance of the multiple window pane 3.

[0031] Figure 3 shows a multiple window pane 3 applied to a partition wall 4 that is thicker than the partition wall 4 in Figure 2. In this configuration, the spacing between the first window 1 and the second window 2 is further increased, so the area G indicated by the arrow in Figure 3 is even larger. In this embodiment, wallpaper or decorative plywood (e.g., 5.5 mm thick) (not shown) is pasted at the area G indicated by the arrow to improve the aesthetic appearance of the multiple window pane 3.

[0032] In the multiple window pane 3 shown in Figure 4, the receiving frame portion 12 of the first window 1 is fixed to a plywood (board) 14 that forms the periphery of the opening 41 in the partition wall 4, and the receiving frame portion 22 of the second window 2 is fixed to the receiving frame portion 12 of the first window 1. In the multiple window pane 3 shown in Figure 4, the receiving frame portion 12 of the first window 1 itself improves the aesthetic appearance of the multiple window pane 3 without the need to attach a decorative member.

[0033] Figure 5 shows a multiple window pane 3 applied to a partition wall 4 that is thicker than the partition wall 4 in Figure 4. Compared to Figure 4, there is no particular difference in the structure of the first window 1 and the second window 2, but the spacing between the first window 1 and the second window 2 is wider. Also, in the multiple window pane 3 shown in Figure 5, the receiving frame portion 12 of the first window 1 itself improves the aesthetic appearance of the multiple window pane 3.

[0034] Figure 6 shows a multiple window pane 3 applied to a partition wall 4 that is thicker than the partition wall 4 in Figure 5. In this configuration, the spacing between the first window 1 and the second window 2 is further increased, but the receiving frame portion 12 of the first window 1 itself improves the aesthetic appearance of the multiple window pane 3.

[0035] In addition, in a thick partition wall 4, three or more windows may be arranged opposite each other and fitted into the opening 41 to form a multiple window.

[0036] In the installation work of the multi-window 3 shown in FIGS. 4, 5, and 6, first, after fixing the plywood 14 of the receiving frame portion 12 of the first window 1 to the cross member 24, the plywood 24 of the receiving frame portion 22 of the second window 2 is fixed to the receiving frame portion 12 of the first window 1. Then, in the second window 2, the second window plate 21 is fixed by the pressing frame portion 23, and then, in the first window 1, the first window plate 11 is fixed by the pressing frame portion 13.

[0037] (Embodiment 2) Hereinafter, other embodiments of the present invention will be described based on FIG. 7. The multi-window 3A of this embodiment has a structure in which the first window 1 and the second window 2 having equal heights are fitted and arranged opposite to the opening 41 of the partition wall 4 of the soundproof room. That is, the second window plate 21 has a length greater than or equal to the height of the inner surface of the receiving frame portion 12 of the first window 1 in the height direction. On the other hand, in the lateral width direction, the second window plate 21 is shorter than the lateral width of the inner surface of the receiving frame portion 12 of the first window 1.

[0038] And the second window plate 21 is in a non-vertical posture (tilted posture) where the upper end face of the second window plate 21 contacts the corner of the contact surface 22a, and the lower end face of the second window plate 21 can exceed the inner surface side corner of the receiving frame portion 12 in the first window 1. Thus, if the lower end face can exceed the inner surface side corner of the receiving frame portion 12, the second window plate 21 can be tilted further in the direction of lying down, and the second window plate 21 can be moved to the inside of the soundproof room.

[0039] Even in the multi-window 3A having such a configuration, with the pressing frame portion 13 and the first window plate 11 of the first window 1 removed and the receiving frame portion 12 remaining, the second window plate 21 can be tilted and taken out and replaced from the arrangement side (inside the soundproof room) of the first window.

[0040] Here, the distance D from the corner of the contact surface 22a to the inner surface side corner of the receiving frame portion 12 (see the virtual line arrow viewing section in the figure) depends on the separation distance between the first window 1 and the second window 2, and when the height of the second window plate 21 is H, the relationship H < D is satisfied with respect to the distance D.

[0041] In the above multiple window 3A, the second window pane 21 is tilted about a horizontal axis along the upper edge face of the second window pane 21, but the same applies when the second window pane 21 is tilted about a horizontal axis along the lower edge face of the second window pane 21. Furthermore, the second window pane 21 can also be tilted about a vertical axis along the left and right edge faces of the second window pane 21, allowing the second window pane 21 to be moved into the soundproof room and replaced. In this configuration, the height of the second window 2 is made shorter than the height of the inner surface of the receiving frame portion 12 of the first window 1.

[0042] In other words, in the multiple window pane 3A of this embodiment, the height or width of the second window pane 21 is greater than or equal to the height or width of the inner surface of the receiving side frame portion 12, while the width or height of the second window pane 21 is less than the width or height of the inner surface of the receiving side frame portion 12, so that it can be removed from the side where the first window 1 is located by passing over the inner corner of the receiving side frame portion 12 in a non-vertical position.

[0043] Furthermore, if the heights and widths of the receiving frame portions 12 and 22 of the first window 1 and the second window 2 are the same, a deep groove will be formed between the receiving frame portion 12 and the holding frame portion 23, and there is a risk that this deep groove will not be able to be properly decorated. In light of this, the multiple window pane 3 shown in Figure 1 etc. has the advantage that such deep grooves are less likely to be formed, making it easier to properly decorate using trim or baseboards.

[0044] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
