Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in order to prevent solar heat from flowing into the room through the window in summer and the room temperature from rising, it is desirable to install a shading member such as a shade or a shutter on the outdoor side of the window. Even if a shading member such as a shutter is provided on the outdoor side of the window in the case of an inward-opening window as in the configuration described in Patent Document 1, the shading member and the window body do not interfere when the window is opened. However, in an opening window such as a sliding window having a structure that opens to the outdoor side, it is difficult to install a shading member on the outdoor side because the shading member and the window body interfere when the window is opened.

[0006] On the other hand, it is also conceivable to install the shading member so as to protrude from the outer wall so that the window and the shading member do not interfere, but the design property is impaired.

[0007] The purpose of this disclosure is to realize a sash window that has a structure that opens outwards, is aesthetically pleasing, and prevents interference between the sunshade member and the window body when the window is opened, even when a sunshade member is installed on the outside of the window. [Means for solving the problem]

[0008] The sash window of this disclosure is a sash window comprising a window frame provided at the edge of an opening in a building, an opening window body attached to the window frame and movable to open outwards, and a sunshade member installed on the outdoor side of the opening window body. [Effects of the Invention]

[0009] According to the sash window described herein, in a structure that opens outwards, it offers excellent design and prevents interference between the sunshade member and the window body when opening the window, even if a sunshade member is installed on the outside of the window. [Brief explanation of the drawing]

[Figure 9] This figure corresponds to Figure 4, showing a sash window in another embodiment. [Modes for carrying out the invention]

[0011] Embodiments of this disclosure will be described below with reference to the drawings. The shapes, materials, and quantities described below are illustrative examples and can be modified as appropriate according to the specifications of the sash window. In all drawings below, equivalent elements will be denoted by the same reference numerals. In addition, in the descriptions within the text, previously mentioned reference numerals will be used as necessary.

[0012] Figure 1 is a perspective view of the sash window 10 of the embodiment, seen from the outside. Figure 2 is a perspective view of the lower part of Figure 1, seen from diagonally above. Figure 3 is an enlarged perspective view including the cross-section cut at section AA of Figure 1. Figure 4 is an enlarged view of the cross-section of Figure 3.

[0013] In Figures 1 to 4, the exterior wall 1 of the building is composed of wall panels 2 as the exterior wall structure. The wall panels 2 include a panel core material 3 assembled in a grid or the like, and an exterior material (not shown) placed on the outdoor side of the panel core material 3.

[0014] The sash window 10 comprises a window frame 12 and an opening window body 28 that is attached to the window frame 12 and is movable to open outwards (for example, in the direction of arrow α in Figure 4). The window frame 12 is a frame provided on the exterior wall 1 of the building, on an opening edge 5 (Figure 3) with a rectangular cross-section formed from a panel core material 3. The opening window body 28 comprises a frame 30 assembled inside the window frame 12 and a glass panel 60 attached inside the frame 30. The glass panel 60 is made of single-pane glass or double-pane glass.

[0015] The sash window 10 is formed as a sliding window in which the frame 30 is supported on the outside side relative to the window frame 12 so as to be able to slide open and close. The vertical frame elements 15 and 16 that extend vertically at both the left and right ends of the window frame 12 and the vertical frame elements 31 and 32 that extend vertically at both the left and right ends of the frame 30 are connected by arm members (not shown).

[0016] As shown in FIGS. 3 to 4, the window frame 12 is formed of resin into a hollow rectangular frame shape. The window frame 12 is fixed to the outer wall 1 of the building by fixing means such as screws in a state of being fitted into the opening edge 5 of the building.

[0017] The frame 30 has a frame body 33 made of resin and formed into a hollow rectangular frame shape, and two resin-made pressing edge portions 34 and 35 annularly provided at the inner peripheral side end portions on both sides in the thickness direction in the frame body 33. The two pressing edge portions 34 and 35 elastically press the outer peripheral side end portion of the glass panel 60 from both sides in the thickness direction. The frame 30 is formed by connecting a horizontal frame element 36 and 37 arranged at both upper and lower ends and extending in the left-right direction and vertical frame elements 31 and 32 arranged at both left and right ends and extending in the up-down direction in a frame shape. The horizontal frame elements 36 and 37 at both upper and lower ends and the vertical frame elements 31 and 32 at both left and right ends respectively correspond to frame members.

[0018] Among the two pressing edge portions 34 and 35, one pressing edge portion 34 provided on the outdoor side is formed by a rectangular frame-shaped pressing edge member 40 which is a separate member from the frame body 33. The pressing edge member 40 has a locking portion 41 fitted and locked into a groove 33a provided over the entire circumference at the outdoor side end portion which is one end portion in the thickness direction of the inner circumference of the frame body 33, and a pressing edge body 42 provided at a portion protruding from the inner peripheral edge of the frame body 33 toward the inner peripheral side, and the cross section is a shape with an inner peripheral side end which is one end of a rectangle opened. The pressing edge body 42 is provided with a groove portion 45 opening toward the inner peripheral side of the frame 30, and each of the groove portions 45 extends along the side of the rectangular inner peripheral edge of the frame 30.

[0019] Also, an airtight member 50 made of rubber is attached to the side surface of the pressing edge body 42 on the glass panel 60 side.

[0020] Thus, the trim member 40 has a groove 45 that is positioned on the outside of the glass panel 60 and opens toward the inner circumference of the frame 30. The groove 45 is provided not only at the lower end of the frame-shaped portion of the frame 30 but also at the upper end. As a result, as shown in Figure 4, a sunshade member 100 such as a retractable or folding shade or shutter that can be unfolded and moved vertically can be installed on the outdoor side of the sash window 10, and the sunshade member 100 can be housed in the groove 45 at either end of the vertical direction. In Figure 4, as an example of a sunshade member 100, a folding shade can be housed in the groove 45 at the lower end. Such grooves 45 are provided so as to be movable integrally with the glass panel 60. Therefore, it is possible to prevent the sunshade member 100 from obstructing the function of the casement window body 28 to open toward the outside. In other words, even if a sunshade member 100 is installed on the outdoor side of the sash window 10, interference between the sunshade member 100 and the casement window body 28 can be prevented. Furthermore, when the sunshade member 100 is not deployed, it can be stored in the groove 45, resulting in superior aesthetics when viewed from the outside.

[0021] Of the two push-edge portions 34 and 35, the other push-edge portion 35 on the indoor side protrudes all the way around from the inner circumference of the indoor end, which is the other end in the thickness direction of the frame body 33. The other push-edge portion 35 is a rectangular frame shape integrated with the other part of the frame body 33. The length of the other push-edge portion 35 in the frame width direction (vertical direction in Figure 4) is the same as the length of the portion of the push-edge member 40 that protrudes inward from the frame body 33 in the frame width direction. A rubber airtight member 51 is attached to the end of the other push-edge portion 35 on the glass panel 60 side. The two push-edge portions 34 and 35 face each other via the airtight members 50 and 51 on both outer surfaces in the thickness direction of the glass panel 60, and the tips of each airtight member 50 and 51 are in contact with the outer surface in the thickness direction of the glass panel 60. Parts of each airtight member 50 and 51 protrude inward from each push-edge portion 34 and 35. The glass panel 60 is held against the frame 30 by the two pressing edges 34 and 35 being pressed against the outer surfaces of the glass panel 60 in the thickness direction via airtight members 50 and 51. Each airtight member 50 and 51 airtightly seals the space between the two pressing edges 34 and 35 and the outer surfaces of the glass panel 60 in the thickness direction.

[0022] The window frame 12 is formed by connecting horizontal frame elements 17 and 18, which are positioned at both ends in the vertical direction and extend in the horizontal direction, and vertical frame elements 15 and 16, which are positioned at both ends in the horizontal direction and extend in the vertical direction, in a frame-like manner, and is attached to the opening edge 5 of the building.

[0023] As shown in Figures 3 and 4, the lower horizontal frame element 18 includes a frame body 19 which is roughly rectangular in shape and has multiple partition plates 18a, 18b, 18c, and 18d provided at multiple positions in the thickness direction of the window frame 12, and a projection 20 with a rectangular cross-section that extends inward from the inner circumference of the indoor end of the frame body 19. A rubber airtight member 21 is attached to the inner circumference end of the outdoor end of the projection 20. The tip of the airtight member 21 is pressed against the side surface of the indoor end of the frame body 33. An extension portion 22 is formed extending inward from the side surface of the indoor end of the frame body 19.

[0024] In the window frame 12, an external projection 80 with a roughly rectangular cross-section extending outward is provided on the outer circumference of the outdoor end. The external projection 80 protrudes outward from the outer surface of the exterior material (not shown). In addition, a butt portion 82 extends outward from the outer circumference of the window frame 12 in a direction perpendicular to the thickness direction of the window frame 12, and this butt portion 82 abuts against the outdoor side of the panel core material 3 to position the window frame 12. The configuration of the upper horizontal frame element 17 is the same as that of the lower horizontal frame element 18, except that the vertical relationship is reversed.

[0025] The configuration of the vertical frame elements 15 and 16 at both ends in the left-right direction is the same as the configuration of the horizontal frame element 17 at the top or the horizontal frame element 18 at the bottom, with only the relationship between the up-down and left-right directions being reversed.

[0026] Furthermore, the configuration of the vertical frame elements 31 and 32 at both ends in the left-right direction is the same as the configuration of the upper horizontal frame element 36 or the lower horizontal frame element 37, with only the relationship between the vertical and left-right directions being reversed. For this reason, in the trim member 40, grooves 45 that open toward the inner circumference of the frame 30 are also provided in the parts that make up each vertical frame element 31 and 32.

[0027] According to the above-described sash window 10, even if a sunshade member 100 is installed on the exterior side of the sash window 10 in a structure that opens outwards, interference between the sunshade member 100 and the casement window body 28 can be prevented. Furthermore, since the sunshade member 100 can be housed in the groove 45 of the push edge member 40 when it is not extended, the sunshade member 100 becomes less visible from the outside. In addition, it is not necessary to install the sunshade member 100 so that it protrudes from the exterior wall 1 to the extent that it does not interfere with the sash window 10. This makes it possible to realize a sash window 10 with a structure that is aesthetically pleasing.

[0028] Furthermore, although the above describes the case in which grooves 45 are provided at both the vertical and horizontal ends of the sash window member 40, the invention is not limited to this, and grooves opening toward the inner circumference of the frame may be provided only at both vertical ends of the outdoor side sash member, or only at one vertical end. On the other hand, as in this embodiment, if the outdoor side sash member 34 is configured such that grooves 45 opening toward the inner circumference of the frame 30 are provided at both vertical ends and both horizontal ends, and the cross section has a rectangular shape with one end open, then the horizontal ends of the sunshade member 100 can be inserted into the grooves 45 at both horizontal ends. As a result, when the sunshade member 100 is extended vertically, the horizontal ends become less visible, further improving the aesthetic appeal.

[0029] Furthermore, as in the embodiment, when the window frame 12 and the stile 30 are each made of resin in at least a portion of their structure, that is, when a resin sash is used, the thermal conductivity is lower and the thermal insulation performance is higher compared to a structure using an aluminum sash frame.

[0030] Figure 5 is a diagram corresponding to Figure 3 in the comparative example sash window 10a. Figure 6 is an enlarged view of the cross section of Figure 5. In the comparative example shown in Figures 5 and 6, the push-edge member 40a provided at the outdoor end of the frame 30a does not have a groove that opens to the inner circumference of the frame 30a. The push-edge member 40a has a flat, hollow cylindrical portion 52 arranged in a frame shape, and a locking portion 53 that engages with the groove 33a is provided on the outer circumference of the cylindrical portion 52.

[0031] In such comparative examples, if a sunshade member is to be installed on the outside of the sash window 10a, the sunshade member and the casement window body 28a interfere with each other when the sash window 10a is opened. Therefore, it is difficult to install a sunshade member on the outdoor side of the sash window 10a. On the other hand, according to the embodiments shown in Figures 1 to 5, such inconveniences can be prevented.

[0032] Figure 7 is a diagram corresponding to Figure 4, showing the first example of a sash window 10b, another embodiment of the design. In this example, unlike the configurations in Figures 1 to 5, the push-edge member 40b provided at the outdoor end of the frame 30b has a rectangular frame-shaped flange portion 54 extending outward from the outer peripheral surface of the outdoor end of the push-edge body 42, which has a rectangular cross-section with one end of the inner peripheral side open. The flange portion 54 is formed at the outer peripheral end of the flange portion 54, which is bent toward the indoor side. The length of the flange portion 54 in the frame width direction (vertical direction in Figure 7) is approximately the same as the length of the outdoor side of the frame body 33 in the frame width direction. The tip of the outer peripheral cylindrical portion 55 is close to and opposite the outer peripheral end of the outdoor side of the frame body 33. As a result, the flange portions 54, which are the outdoor ends at both the vertical ends of the push-edge member 40b, are extended outward, covering the outdoor sides of the horizontal frame elements 37 at both the vertical ends.

[0033] With this configuration, the outdoor side of the frame 30b becomes a wide, flat surface perpendicular to the thickness direction of the sash window 10b, reducing the step difference near the outer perimeter of the sash window 10b. This further improves the aesthetic appeal of the sash window 10b. In this example, the other configurations and functions are the same as those in Figures 1 to 5.

[0034] Figure 8 is a diagram corresponding to Figure 4, showing a second example of a sash window 10c, another embodiment of the design. In this example, the frame body 33b of the frame 30c extends further outward at its outdoor end than the frame body 33 in the configurations of Figures 1 to 5, resulting in a greater length of the frame body 33b in the thickness direction of the frame 30c. The outdoor side surface of the frame body 33b is positioned on the same plane as the outdoor side surface of the trim member 40. As a result, the outdoor side surface of the frame 30c, together with the frame body 33b and the trim member 40, forms a wide, planar surface perpendicular to the thickness direction of the sash window 10c, thus reducing the step difference near the outer periphery of the sash window 10c. This further improves the aesthetic appeal of the sash window 10c. In this example, the other configurations and functions are the same as those in the configurations of Figures 1 to 5.

[0035] Figure 9 is a diagram corresponding to Figure 4, showing a third example of a sash window 10d, which is another embodiment of the present invention. In this example, of the two pressing edges 34a and 35a of the frame 30d, the outdoor pressing edge 34a is provided integrally with the other parts of the frame body 33c as part of the frame body 33c. The pressing edge 34a is a rectangular frame shape with an open inner circumference on the frame 30d, and a groove 45 is formed therein. Furthermore, a rubber airtight member 50 is attached to the end of the outdoor pressing edge 34a on the glass panel 60 side, and presses against the side surface of the glass panel 60.

[0036] On the other hand, of the two pressing edges 34a and 35a, the indoor pressing edge 35a is formed by a rectangular frame-shaped pressing edge member 70, which is a separate component from the frame body 33c. The pressing edge member 70 has a locking portion 71 that is fitted and locked into a groove 33d provided around the entire circumference of the indoor end of the inner circumference of the frame body 33c, and a pressing edge body 72 with a rectangular cross-section that is provided on the portion that protrudes inward from the inner edge of the frame body 33c. A rubber airtight member 51 is attached to the side of the pressing edge body 72 on the glass panel 60 side, and presses against the side of the glass panel 60. In this example, the other configurations and functions are the same as those in Figures 1 to 5.

[0037] In the embodiments described above, the configuration of the present disclosure was explained in the case of applying it to a casement window. However, the type of window is not limited to these, and the configuration of the present disclosure can be applied to various types of windows as long as the window opens outwards. Furthermore, in the embodiments described above, the configuration of the present disclosure was explained in the case of applying it to a structure using a resin sash. However, the configuration of the present disclosure can also be applied to a structure using a metal sash, such as an aluminum sash frame.
