Description

Technical Field

[0001] The present disclosure relates to a window structure.

Background Art

[0002] Patent Document 1 discloses an end cover for draining water of a window frame sash. This end cover for draining water of the window frame sash is, for example, for covering the end of the drain located at the waist portion of the window frame sash.

[0003] Patent Document 1 discloses that the end of the drain of the aluminum sash member is in a cut-off state, and as it is, a sharp edge is formed. In particular, in a structure where the drain is located at the waist portion of the window frame sash, there are safety problems such as the user being injured by the sharp edge of the exposed end. It is also disclosed that when covering the end of the drain with an end plate during on-site processing, operations such as bending or chamfering the end plate are required. Further, in order to completely cover such an edge by forming an end cover through on-site processing, not only a great deal of labor is required, but the appearance after construction is also not favorable.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As exemplified in Patent Document 1, in a window structure, devices such as attaching a cover to a portion where the base material is exposed, such as the end of an aluminum sash, have been made.

[0006] In particular, with window structures equipped with shutters, a construction method is sometimes employed in which a portion of the sash frame is cut out before the shutter is fixed to the sash frame. As a result, there are uncovered areas on the sash frame, such as cut marks, and there is a demand to cover these uncovered areas.

[0007] However, depending on the location of the bare material to be covered and the method of covering, there was a risk of compromising the watertight performance of the window structure or increasing the amount of work required on site.

[0008] For example, in a method of attaching a cover member by forming mounting holes in the sash frame as through-holes for attaching the cover member and using these mounting holes to fix the cover member to the sash frame, there was a risk of impairing the watertight performance of the window structure due to the formation of mounting holes. Also, when painting areas where the base material is exposed (so-called touch-up painting), the amount of work increases, and there was a problem that the paint was more likely to peel off and had lower durability compared to when the area was covered with a cover member. Therefore, in the structure of a window equipped with a shutter, there is a need to provide a window structure that covers the base material with less work effort and without impairing watertight performance.

[Figure 7] This is a magnified view of section C shown in Figure 6. [Figure 8] This is an explanatory diagram showing the lower end of the cover component sealed. [Modes for carrying out the invention]

[0027] A window structure according to an embodiment of this disclosure will be described based on the drawings.

[0028] As shown in Figures 1 and 2, the window structure 100 according to this embodiment comprises a sash frame portion 1, a shutter frame portion 5 positioned adjacent to the sash frame portion 1 on the outdoor side in the depth direction of the sash frame portion 1, and a cover member 8 positioned adjacent to the sash frame portion 1 on the outdoor side. As shown in Figure 2, the sash frame portion 1 has a covered portion 31 on its outdoor surface that is covered with a base material and a base material portion 32 that is not covered with a base material, and the cover member 8 covers the base material portion 32.

[0029] The window structure 100 is a window structure equipped with a shutter that covers the base material 32 without compromising watertightness and with minimal labor required for installation.

[0030] The following provides a detailed description of window structure 100.

[0031] The window structure 100 is used as one of the window structures in a building such as a multi-story house with a steel frame. The building in which the window structure 100 described below is used may consist of a reinforced concrete foundation, a frame structure composed of framing members such as columns and beams, and a superstructure fixed to the foundation, which has panels forming walls 9 and floors. The framing members and panels can be standardized in advance. In this case, the framing members and other components can be manufactured in advance at a factory and transported to the construction site for assembly. The window structure 100 may be partially or entirely constructed at a factory, or partially or entirely constructed at the building's construction site.

[0032] As shown in Figure 1, the window structure 100 comprises a sash frame 1, a shutter frame 5, and a cover member 8, as described above. The window structure 100 is constructed, for example, on the wall 9 of a building. Figure 1 shows a front view of the window structure 100 as seen from the outside of the building, along the depth direction of the sash frame 1 of the window structure 100. Here, "outside" refers to the area outside the building where the window structure 100 is installed. Hereafter, the viewpoint along the depth direction of the sash frame 1 will be referred to as the front view. Here, the depth direction of the sash frame 1 refers to the depth direction of the sash frame 1.

[0033] Figure 2 shows a magnified view of section A shown in Figure 1. Figure 3 shows a magnified view of section B shown in Figure 2. Figure 4 shows a cross-sectional view taken along the line IV-IV shown in Figure 1. Figure 5 shows a cross-sectional view taken along the line V-V shown in Figure 1. Figure 6 shows a cross-sectional view taken along the line VI-VI shown in Figure 1.

[0034] As shown in Figure 1, the sash frame 1 is installed on the wall 9 and is a rectangular-shaped frame in a front view that slidably holds the sash 4 and the like.

[0035] The sash frame section 1 may have vertical sash frames 11, 11 arranged on the left and right sides of its rectangle, an upper horizontal sash frame (not shown) arranged at the top of the rectangle, and a lower horizontal sash frame 15 arranged at the bottom of the rectangle.

[0036] As shown in Figures 4 to 6, the boundary between the sash frame 1 and the wall 9 may be sealed (filled) with a sealant 99 or the like.

[0037] The sash frame 1 shown in Figure 1 may be formed from a metal frame, such as an aluminum frame (a frame material whose base material is mainly aluminum). The sash frame 1 may be covered with a coating, such as a paint film, on its base aluminum substrate (i.e., it may be painted).

[0038] As shown in Figures 2 and 3, the sash frame portion 1 of this embodiment has a coated portion 31 on its outdoor surface, which is covered with, for example, paint, and a bare portion 32, which is the part where the base material is not covered with a coating, i.e., the aluminum is exposed. Details of the coated portion 31 and the bare portion 32 will be described later.

[0039] As shown in Figure 1, the sash vertical frames 11,11 are frame members that extend along the vertical direction (the same as the vertical direction). In Figure 1 and other figures, the sash vertical frame 11 on the left side in a front view is shown as sash vertical frame 11L. Similarly, the sash vertical frame 11 on the right side in a front view is shown as sash vertical frame 11R. In the following explanation, sash vertical frame 11R will be described as sash vertical frame 11, but this explanation is the same for sash vertical frame 11L, except that the left and right sides are reversed.

[0040] The vertical sash frame 11 may be supported by the studs 92 of the wall 9, for example, as shown in Figure 4. That is, the sash frame portion 1 may be supported by the studs 92. The studs 92 are columns that extend vertically in the wall 9. The studs 92 may be positioned on the outdoor side of the wall 9, beyond the interior wall material 91 on the indoor side. Here, "indoors" refers to the space within the building equipped with the window structure 100 (the so-called interior). The studs 92 may also be positioned between the exterior wall material 93 and the sash frame portion 1 of the wall 9. Furthermore, the studs 92 may be positioned on the indoor side of the outer surface of the exterior wall material 93 on the outdoor side.

[0041] As shown in Figure 4, the vertical sash frame 11 has rib-shaped rib portions 21 and 22 that extend outward and along the direction of extension of the vertical sash frame 11, i.e., along the vertical direction. Rib portion 21 is the rib that is on the outside in the in-plane direction of the opening of the sash frame 1 compared to rib portion 22. To illustrate with an example of the vertical sash frame 11R, rib portion 21 is the rib located to the right of rib portion 22.

[0042] Furthermore, the sash vertical frame 11 has rib-removed sections 23 and 24 at its lower end, where the rib portions 21 and 22 (see Figures 2 and 4) have been removed, as shown in Figures 2 and 3. In other words, the rib-removed sections 23 and 24 are located at the lower end of the sash vertical frame 11.

[0043] The rib-removed portions 23 and 24 extend downward from the lower ends of the rib portions 21 and 22, along the direction of extension of the rib portions 21 and 22.

[0044] In other words, the sash vertical frame 11 is formed by cutting off the rib portions 21 and 22 at one end (lower end) from a frame material that has rib portions 21 and 22 formed from one end to the other in its extending direction.

[0045] In the rib-removed sections 23 and 24, the bare aluminum is exposed due to the removal of the rib sections 21 and 22, forming the bare aluminum section 32.

[0046] As shown in Figure 1, the lower horizontal frame 15 of the sash is a frame member that extends along the left-right direction (a direction perpendicular to the vertical direction). The lower horizontal frame 15 of the sash is the lower horizontal frame of the rectangular sash frame section 1 when viewed from the front. The lower horizontal frame 15 of the sash may be supported by a window sill 95 of the wall 9, for example, as shown in Figure 5. That is, the sash frame section 1 may be supported by a window sill 95. The window sill 95 is a horizontal member that extends along the left-right direction in the wall 9.

[0047] In the sash frame section 1, as shown in Figure 4, the relationship between the sash vertical frame 11 and the sash lower horizontal frame 15 is such that the vertical orientation prevails. In other words, the sash frame section 1 is constructed in such a way that the end face (edge ​​face) of the sash lower horizontal frame 15 in the left-right direction faces the sash vertical frame 11.

[0048] The shoji screen 4 may, for example, have a transparent plate 40 such as glass and a rectangular frame 41 that holds the transparent plate 40. Figure 1 illustrates a case in which two shoji screens 4, 4 are fitted into the frame of the sash frame 1 in a manner that allows them to slide open and close together.

[0049] As shown in Figures 1 to 6, the shutter frame 5 is a shutter frame positioned adjacent to the sash frame 1 on the outdoor side in the depth direction of the sash frame 1. The shutter frame 5 is a rectangular frame in a front view that slidably holds the slats (not shown).

[0050] As shown in Figure 1, the shutter frame 5 may have vertical shutter frames 51, 51 arranged on the left and right sides of its rectangle, a slat housing section 50 (not shown) located at the top of the rectangle and extending in the left-right direction, and a lower horizontal shutter frame 55 located at the bottom of the rectangle.

[0051] The shutter frame 5 may be formed from a metal frame, such as an aluminum frame. The shutter frame 5 may be covered with a coating, such as a paint film, on its aluminum base material (i.e., it may be painted).

[0052] The shutter frame portion 5 of this embodiment may have, similar to the sash frame portion 1, a coated portion on its outdoor surface where the base material is covered with, for example, paint, and a bare portion where the base material is not covered with a coating, i.e., the aluminum is exposed.

[0053] The shutter vertical frames 51, 51 are frame members that extend along the vertical direction (the same as the vertical direction). In Figure 1, etc., the left shutter vertical frame 51 in a front view is shown as shutter vertical frame 51L. Also, the right shutter vertical frame 51 in a front view is shown as shutter vertical frame 51R. In the following, shutter vertical frame 51R will be described as shutter vertical frame 51, but this description is the same for shutter vertical frame 51L, except that the left and right sides are reversed.

[0054] As shown in Figures 1 to 4, the shutter vertical frame 51 overlaps with the sash vertical frame 11 in the sash frame section 1 in the depth direction.

[0055] The shutter vertical frame 51 may be supported, for example, by the rib portions 21 and 22 of the sash vertical frame 11 in the sash frame portion 1, as shown in Figure 4.

[0056] In this embodiment, the shutter vertical frame 51 extends toward the indoor side in the depth direction of the sash frame portion 1 of the window structure 100 and has rib-shaped rib portions 61 and 62 that extend along the shutter vertical frame 51, i.e., along the vertical direction.

[0057] The shutter vertical frame 51 may be supported by the sash vertical frame 11 by having its rib portion 61 locked to the rib portion 21. Alternatively, the shutter vertical frame 51 may be supported by the sash vertical frame 11 by having its rib portion 62 locked to the rib portion 22.

[0058] For example, the rib portion 61 and the rib portion 21 may each have hook-shaped tips, and the shutter vertical frame 51 may be supported by the sash vertical frame 11 by interlocking these hook-shaped portions with each other.

[0059] For example, the rib portion 62 and the rib portion 22 can be supported by the sash vertical frame 11, with the rib portion 62 being fixed to the rib portion 22 with a screw 59.

[0060] The lower horizontal frame 55 of the shutter is a frame material that extends along the left-right direction (a direction perpendicular to the vertical direction). The lower horizontal frame 55 of the shutter is the lower horizontal frame of the rectangular shutter frame section 5 when viewed from the front.

[0061] As shown in Figures 1 to 5, the lower horizontal frame 55 of the shutter overlaps with the lower horizontal frame 15 of the sash frame section 1 in the depth direction.

[0062] As shown in Figures 1 to 3 and Figure 5, in this embodiment, the lower end of the lower horizontal frame 55 of the shutter is located above the lower end of the lower horizontal frame 15 of the sash and the lower end of the vertical frame 11 of the sash in the sash frame section 1.

[0063] The lower horizontal frame 55 of the shutter may be supported by the lower horizontal frame 15 of the sash frame 1, for example, as shown in Figure 5. The lower horizontal frame 55 of the shutter may be supported by the lower horizontal frame 15 of the sash frame 15 by hooking its lower end 55b onto a claw portion 15a that forms a downwardly recessed rail-shaped recess formed on the outdoor side of the lower horizontal frame 15, or by fixing it with screws.

[0064] In this embodiment, as shown in Figure 1, the relationship between the shutter vertical frame 51 and the shutter lower horizontal frame 55 is horizontally dominant. That is, the shutter frame 5 is constructed in such a way that the lower end surface (outer edge) of the shutter vertical frame 51 faces the shutter lower horizontal frame 55.

[0065] As shown in Figures 1 to 3, in this embodiment, the left and right ends of the lower horizontal frame 55 of the shutter overlap in the depth direction with the lower end of the vertical frame 11 of the sash frame 1. Therefore, as shown in Figures 2 and 3, in the vertical frame 11 of the sash, the rib portions 21 and 22 are cut off at the lower end of the vertical frame 11 of the sash to avoid three-dimensional interference between the rib portions 21 and 22 and the lower horizontal frame 55 of the shutter. In this embodiment, as described above, the cut marks left by the removal of these rib portions 21 and 22 are referred to as rib cut sections 23 and 24.

[0066] As described above, and as shown in Figures 2 and 3, the left and right ends of the lower horizontal frame 55 of the shutter overlap in the depth direction with the lower end of the vertical frame 11 of the sash frame 1, but the lower end of the lower horizontal frame 55 of the shutter is located above the lower end of the vertical frame 11 of the sash frame. Due to this positional relationship, the upper ends of the rib-cut portions 23 and 24 (an example of a part of the rib-cut portion) are covered by the vertical frame 51 of the shutter or the lower horizontal frame 55 of the shutter, but the lower ends of the rib-cut portions 23 and 24 (an example of the remaining part of the rib-cut portion) are not covered by the lower horizontal frame 55 of the shutter. Therefore, in this embodiment, the lower ends of the rib-cut portions 23 and 24 (the remaining part of the rib-cut portions 23 and 24 that is covered by the vertical frame 51 of the shutter or the lower horizontal frame 55 of the shutter, that is, the part of the bare material 32 such as the rib-cut portions 23 and 24 that is not covered by the vertical frame 51 of the shutter or the lower horizontal frame 55 of the shutter) are covered by a separately provided cover member 8.

[0067] In the following explanation, we will use the cover member 8 (the cover member 8 on the side of the sash vertical frame 11R) located on the right side of the window structure 100 as shown in Figure 1 as an example. However, the following explanation is the same for the cover member 8 (the cover member 8 on the side of the sash vertical frame 11L) located on the left side of the window structure 100, except that the left and right sides are reversed.

[0068] As described above, the cover member 8 is a member that covers the exposed portion of the bare material 32, such as the rib-cut portions 23 and 24, that is not covered by the shutter vertical frame 51 or the shutter lower horizontal frame 55 (hereinafter referred to as the remaining portion of the rib-cut portions 23 and 24), that is, the exposed portion of the bare material 32, from the outside. The cover member 8 can hide the bare material 32 and improve the aesthetic appearance of the window structure 100. In addition, it can protect the bare material 32 from the outdoor environment and improve the durability of the window structure 100.

[0069] In this embodiment, as shown in Figures 2, 3, and 6, the cover member 8, along with the remaining portions of the rib-cut portions 23 and 24 (see Figures 2 and 3), covers a portion of the left-right ends of the lower horizontal frame 55 of the shutter in the shutter frame portion 5, and a portion of the lower end of the sash vertical frame 11, from the outside. The cover member 8 may further cover a portion of the lower horizontal frame 15 of the sash (see Figures 2 and 3).

[0070] In this embodiment, as shown in Figures 2, 3, and 6, the cover member 8 is a plate-shaped member that covers the remaining portion of the rib-cut portions 23 and 24 (see Figures 2 and 3, the bare material portion 32) and extends from the outdoor surface of the sash vertical frame 11 (mainly the covering portion 31) to the outdoor surface of the lower horizontal frame 55 of the shutter, and along these surfaces. The cover member 8 may be formed from a metal base material such as aluminum.

[0071] The cover member 8 is positioned adjacent to the sash vertical frame 11 and the lower horizontal frame 55 of the shutter. The cover member 8 may be attached to the sash frame 1 and the shutter frame 5 in a state where it is in contact with the outdoor surface of the sash vertical frame 11 and the outdoor surface of the lower horizontal frame 55 of the shutter. The cover member 8 may be shaped in a curved form so as to conform to the outdoor surface of the sash vertical frame 11 and the outdoor surface of the lower horizontal frame 55 of the shutter. By attaching the cover member 8 to the sash frame 1 and the shutter frame 5 to cover the bare material 32 (see Figures 2 and 3), the bare material 32 can be covered with less labor compared to covering the bare material 32 with paint such as touch-up paint.

[0072] The cover member 8 is fixed to the lower horizontal frame 55 of the shutter in the shutter frame portion 5. For example, the cover member 8 may be fixed to the lower horizontal frame 55 of the shutter using a connecting structure such as a rivet or a snap-fit.

[0073] Figure 7 shows a case where a through hole 55H is formed in the lower surface 55a of the lower horizontal frame 55 of the shutter. It also shows a case where a snap-fit ​​structure 81 extending from the back surface (the surface facing the lower horizontal frame 55 of the shutter) is formed on the back surface of the cover member 8. In this example, the through hole 55H is used as a mounting hole, and the snap-fit ​​structure 81 is fitted into the through hole 55H to fix the cover member 8 to the lower surface 55a of the lower horizontal frame 55 of the shutter in the shutter frame 5. Note that Figure 7 is a magnified view of section C shown in Figure 6.

[0074] In the example shown in Figure 7, the cover member 8 is not fixed to the vertical sash frame 11 in the sash frame portion 1, but merely abuts against the vertical sash frame 11. In this embodiment, "the cover member 8 is not fixed to the vertical sash frame 11" means that there are no through holes formed in the vertical sash frame 11 for fixing the cover member 8 (for example, by screwing it in). In this way, by fixing the cover member 8 to the shutter frame portion 5, such as the lower horizontal frame 55 of the shutter, rather than fixing it to the sash frame portion 1, such as the vertical sash frame 11, it is possible to avoid a decrease in the water-sealing performance of the window structure 100 (see Figure 1, etc.), i.e., the sash frame portion 1 (impairing its water-sealing performance).

[0075] Figures 4 to 6 show an example of a boundary in the window structure 100 where water intrusion from the outside to the inside should be prevented, as shown as the watertight line P. By fixing the cover member 8 to the shutter frame 5 and not fixing the cover member 8 to the sash frame 1 with screws or the like, it is possible to avoid processing the sash frame 1, such as the sash vertical frame 11, which would affect the watertight line P (for example, drilling holes or screwing), and thus avoid a decrease in the watertight performance of the sash frame 1.

[0076] As shown in Figure 7, the lower end portion 82 of the cover member 8 should be thinner towards the bottom. Note that the thickness of the lower end portion 82 in Figure 7 refers to the thickness in the depth direction. By making the thickness of the lower end portion 82 thinner towards the bottom, the cover member 8 becomes less conspicuous, and the aesthetic appearance of the window structure 100 (see Figure 1, etc.) can be improved.

[0077] It is desirable that the lower end of the cover member 8 is located above the lower end of the sash frame portion 1 that is exposed to the outside, that is, above the lower end of the sash vertical frame 11 or the lower horizontal frame 15 of the sash that is exposed to the outside (see Figure 5). In other words, it is desirable that the lower end of the cover member 8 is located below the lower end of the shutter lower horizontal frame 55 in the shutter frame portion 5, and above the lower end of the sash vertical frame 11 or the lower horizontal frame 15 of the sash frame portion 1. This ensures a gap between the lower end of the cover member 8 and the lower end of the sash frame portion 1, as shown in Figure 8, and ensures a sealing allowance when sealing the gap between the lower end of the cover member 8 and the lower end of the sash frame portion 1 with sealant 89. Note that sealant 89 is not essential. Also, the sealing between the lower end of the cover member 8 and the lower end of the sash frame portion 1 by sealant 89 is not included in the concept of fixing the cover member 8 to the sash frame portion 1.

[0078] It is desirable that the lower end of the cover member 8 is located 1 mm to 3 mm above the lower end of the sash frame 1 that is exposed to the outside. By ensuring a gap within this range, this gap becomes sufficient as a sealing allowance, and the aesthetic appearance of the window structure 100 (see Figure 1, etc.) when the gap between the lower end of the cover member 8 and the lower end of the sash frame 1 is sealed with sealant 89 can be improved.

[0079] The exterior color of the cover member 8 is preferably the same as or similar to the exterior color of the sash frame 1 or the shutter frame 5 shown in Figure 1, i.e., an approximate color. This improves the aesthetic design of the window structure 100. It is even more preferable that the exterior colors of the sash frame 1, the shutter frame 5, and the cover member 8 are approximate colors. Note that the exterior color of the sash frame 1, etc., refers to, for example, the color of the coating (e.g., paint film) on their surfaces.

[0080] As described above, in a window structure equipped with a shutter, it is possible to provide a window structure that covers the base material with minimal labor and without compromising watertightness.
