Description

Technical Field

[0001] The invention relates to a door and window. Background Art

[0002] When a frame or a door or window sash is formed by using a longitudinal profile and a transverse profile, the transverse profile is connected to the depth surface of the longitudinal profile through its cut end surface. A sealing member formed in a sheet shape is usually sandwiched between the longitudinal profile and the transverse profile to ensure the desired water tightness at the joint between the two (for example, see Patent Document 1).

[0003] Patent Document 1: Japanese Utility Model Application Laid-Open No. 57-174681 Summary of the invention

[0004] In addition, among the doors and windows that consider heat insulation, there are doors and windows that have non-metal parts formed of resin or wood in addition to metal parts formed of metal such as aluminum alloy as their longitudinal profiles or transverse profiles. That is, by providing the non-metal parts on the indoor side, even when there is a temperature difference between indoor and outdoor, it is possible to prevent condensation from occurring on the frame or the door and window sashes.

[0005] At this time, the longitudinal profile and the transverse profile are not necessarily connected by the same material, and there may be a case where the metal formed part is connected to the non-metal formed part. Therefore, for example, in the case where the transverse profile is connected to the non-metal formed part of the longitudinal profile through the metal formed part, depending on the screwing state of the screw component, the metal formed part as the cut end face in the transverse profile may bite into the resin or wood of the non-metal formed part of the longitudinal profile, causing deformation such as deformation. In the event of such a situation, it will be difficult to ensure the watertightness between the longitudinal profile and the transverse profile. In particular, in the case where the non-metal formed part is wood, there is also a risk that water will enter the interior from the biting part and cause the wood to rot prematurely.

[0006] The present invention is proposed in view of the above-mentioned actual situation, and its object is to provide a door and window that can connect the longitudinal profile with the transverse profile without causing deformation of the longitudinal profile.

[0007] In order to achieve the above-mentioned purpose, the doors and windows of the present invention include a longitudinal profile and a transverse profile, the longitudinal profile having a first formed portion, the transverse profile having a second formed portion with a harderness than that of the first formed portion, and the transverse profile being connected to the depth surface of the longitudinal profile serving as the inner peripheral side through its cut end surface at positions where the first formed portion and the second formed portion correspond to each other, and in the doors and windows, a reinforcing plate with a harderness than that of the first formed portion is sandwiched between the first formed portion and the second formed portion.

[0008] According to the present invention, since a reinforcing plate having a harderness than the first formed portion is sandwiched between the first formed portion of the longitudinal profile and the second formed portion of the transverse profile, even when a screw component is screwed into the longitudinal profile and the transverse profile, deformation such as the transverse profile biting into the longitudinal profile will not occur.

DETAILED DESCRIPTION

[0028] Hereinafter, the preferred embodiments of the doors and windows of the present invention will be described in detail with reference to the accompanying drawings. In addition, in the following, for the sake of convenience, the terms such as depth direction and main viewing direction are sometimes used. The so-called depth direction refers to the direction along the depth of the doors and windows as shown by the arrow A in the figure. The surface along the depth direction is sometimes called the depth surface. The so-called main viewing direction, if it is a component extending in the horizontal direction such as the lower frame, refers to the direction orthogonal to the depth direction and along the up and down direction. If it is a component extending in the up and down direction such as the vertical frame, the direction orthogonal to the depth direction and along the horizontal direction is called the main viewing direction. The surface along the main viewing direction is sometimes called the main viewing surface.

[0029] Figure 1 to Figure 3: is a diagram showing a door and window according to an embodiment of the present invention. The door and window illustrated here is a window called a single-leaf sliding window, which is composed of a frame 10, a fixed window sash 20 and a movable window sash 30 arranged on the frame 10. The frame 10 is composed of an upper frame (frame material) 11, a lower frame 12 and left and right longitudinal frames (frame materials) 13, 14 assembled around. Inside the frame 10, a middle vertical frame 15 is arranged between the upper frame 11 and the lower frame 12 along the up and down direction. The upper frame 11, the lower frame 12 and the left and right longitudinal frames 13, 14 constituting the frame 10 are configured to have approximately the same dimensions along the depth direction. In contrast, the middle vertical frame 15 is configured to have a smaller dimension along the depth direction than the upper frame 11, and is installed in the upper frame 11 and the lower frame 12, respectively, in the portion serving as the outdoor side, at a position approximately equidistant from the left and right longitudinal frames 13, 14.

[0030] like Figure 1 , Figure 3 As shown, the fixed window sash 20 is formed by arranging a multi-layer glass panel 21 in a portion surrounded by an upper frame 11, a lower frame 12, a longitudinal frame 13 on one side, and a middle vertical frame 15. In this embodiment, the fixed window sash 20 is arranged between the longitudinal frame located on the right side (hereinafter referred to as the right longitudinal frame 13 when it is necessary to distinguish) and the middle vertical frame 15 when viewed from the indoor side. The movable window sash 30 is formed by installing an upper frame 32, a lower frame 33, and left and right longitudinal frames 34 and 35 around a quadrilateral multi-layer glass panel 31, and is arranged in a portion of the frame 10 that is closer to the indoor side than the middle vertical frame 15 so as to slide left and right. When the movable window sash 30 is arranged in the closed position relative to the frame 10, the longitudinal frame 34 arranged on the right side and the middle vertical frame 15 are arranged side by side in the depth direction when viewed from the indoor side, and the longitudinal frame 35 arranged on the left side when viewed from the indoor side and the longitudinal frame arranged on the left side when viewed from the indoor side (hereinafter referred to as the left longitudinal frame 14 when necessary) are in contact with each other through the sealing material 1.

The dimension of the outer peripheral main view plate part 51 along the main view direction is substantially equal to the dimension of the wood frame forming part 11A of the upper frame 11 from the first outer peripheral depth surface 43 to the upper edge position of the inclined surface 44a along the main view direction. The outer peripheral engaging plate part 52 extends from the edge of the outer peripheral main view plate part 51 located on the outer peripheral side toward the room, and then bends at a substantially right angle toward the inner peripheral side. The outer peripheral depth plate portion 53 extends approximately horizontally in the depth direction from the edge of the outer peripheral main viewing plate portion 51 as the inner peripheral side toward the outside, and then slightly tilts toward the inner peripheral side toward the outside. The dimension along the depth direction of the outer peripheral depth plate portion 53 is configured to be larger than the dimension along the depth direction from the first outdoor main viewing surface 44 to the second outdoor main viewing surface 46 in the wood frame forming portion 11A of the upper frame 11. The extended edge of the outer peripheral depth plate portion 53 is bent toward the inner peripheral side. The support leg plate portion 54 protrudes from the depth surface of the outer peripheral depth plate portion 53 as the inner peripheral side toward the inner peripheral side. The dimension along the depth direction from the outer peripheral main viewing plate portion 51 to the support leg plate portion 54 is set to be smaller than the dimension along the depth direction from the first outdoor main viewing surface 44 to the second outdoor main viewing surface 46. The screw hole 55 protrudes downward from the portion of the outer peripheral depth plate portion 53 that is the depth surface of the inner circumference and is closer to the indoor side than the support leg plate portion 54, and is formed into a generally cylindrical shape with an inner circumference opening. The dimension of the screw hole 55 protruding from the outer peripheral depth plate portion 53 is roughly the same as the dimension of the support leg plate portion 54 protruding from the outer peripheral depth plate portion 53. The inner peripheral main viewing plate portion 56 extends from the portion of the outer peripheral depth plate portion 53 that is the depth surface of the inner circumference and is closer to the outdoor side than the support leg plate portion 54 toward the inner circumference along the main viewing direction. The dimension along the depth direction from the outer peripheral main viewing plate portion 51 to the inner peripheral main viewing plate portion 56 is set to be larger than the dimension along the depth direction from the first outdoor main viewing surface 44 to the second outdoor main viewing surface 46.

The inner peripheral depth plate portion 57 extends from the inner peripheral edge of the inner peripheral main viewing plate portion 56 toward the indoor room in the depth direction. The extended edge of the inner peripheral depth plate portion 57 is bent toward the outer peripheral side. The dimension from the bent edge of the inner peripheral depth plate portion 57 to the bent edge of the outer peripheral engaging plate portion 52 is substantially equal to the dimension along the depth direction from the outer peripheral side engaging groove 43a to the inner peripheral side engaging groove 41a. The main viewing cover arm portion 58 extends from the inner peripheral edge of the inner peripheral main viewing plate portion 56 toward the outdoor room in the depth direction, and then extends toward the inner peripheral side in the main viewing direction. The inner protruding plate portion 59 extends from the extended edge of the main viewing cover arm portion 58 toward the indoor room.A groove portion 59 a opening toward the interior of the room is provided at an extended edge portion of the inner protruding plate portion 59 .

[0036] The metal frame forming parts (third forming parts) 13B and 14B of the longitudinal frames 13 and 14 are formed by integrally forming the outer peripheral main view plate part 61, the outer peripheral engaging plate part 62, the outer peripheral depth plate part 63, the inner peripheral main view plate part 64, and the inner peripheral depth plate part 65. The outer peripheral main view plate part 61 extends along the main view direction. The dimension of the outer peripheral main view plate part 61 along the main view direction is slightly smaller than the dimension along the main view direction from the first outer peripheral depth surface 43 to the second outer peripheral depth surface 45 in the wood frame forming parts 13A and 14A of the longitudinal frames 13 and 14. The outer peripheral engaging plate part 62 extends from the edge of the outer peripheral main view plate part 61 on the outer peripheral side toward the room, and then bends at a substantially right angle toward the inner peripheral side. The outer peripheral depth plate part 63 extends substantially horizontally along the depth direction from the edge of the outer peripheral main view plate part 61 on the inner peripheral side toward the outside of the room. The dimension along the depth direction of the outer peripheral depth plate portion 63 is configured to be larger than the dimension along the depth direction from the first outdoor main viewing surface 44 to the second outdoor main viewing surface 46 in the wood frame forming portion 13A, 14A of the longitudinal frame 13, 14. The inner peripheral main viewing plate portion 64 extends from the depth surface as the inner peripheral side of the outer peripheral depth plate portion 63 toward the inner peripheral side along the main viewing direction, and then bends toward the room and extends. A groove portion 64a opening toward the room is provided at the extended edge of the portion of the inner peripheral main viewing plate portion 64 extending toward the room. The dimension along the depth direction from the outer peripheral main viewing plate portion 61 to the inner peripheral main viewing plate portion 64 is set to be larger than the dimension along the depth direction from the first outdoor main viewing surface 44 to the second outdoor main viewing surface 46. The dimension along the main viewing direction from the outer peripheral depth plate portion 63 to the edge of the inner peripheral main viewing plate portion 64 located on the inner peripheral side is larger than the dimension along the main viewing direction from the second outer peripheral depth surface 45 to the inner peripheral depth surface 41. The inner peripheral depth plate portion 65 extends from the main viewing surface of the inner peripheral main viewing plate portion 64 facing the room toward the room in the depth direction. The extended edge of the inner peripheral depth plate portion 65 is bent toward the outer peripheral side. The dimension along the main viewing direction from the outer peripheral depth plate portion 63 to the inner peripheral depth plate portion 65 is slightly larger than the dimension from the second outer peripheral depth surface 45 to the inner peripheral depth surface 41. The dimension from the bent edge of the inner peripheral depth plate portion 65 to the bent edge of the outer peripheral engaging plate portion 62 is approximately equal to the dimension along the depth direction from the outer peripheral side engaging groove 43a to the inner peripheral side engaging groove 41a.

[0037] The metal frame forming part 11B of the upper frame 11 is maintained in a state of being attached to the wood frame forming part 11A of the upper frame 11 by engaging the bent extension of the outer peripheral engaging plate part 52 with the outer peripheral side engaging groove 43a and engaging the bent extension of the inner peripheral depth plate part 57 with the inner peripheral side engaging groove 41a. In this state, the outer peripheral main viewing plate part 51 is in contact with the first outdoor main viewing surface 44, and the outer peripheral depth plate part 53 is in contact with the second outer peripheral depth surface 45 through the support leg plate part 54, and the outer edge surface 11a facing the outside is provided along the main viewing direction at the outer peripheral side portion of the upper frame 11 by the outer peripheral main viewing plate part 51. In the wood frame forming part 11A of the upper frame 11, the portion closer to the indoor side than the middle vertical frame 15 is provided with an upper guide rail 11C over substantially the entire length along the longitudinal direction of the depth surface as the inner peripheral side. The upper guide rail 11C is used to guide the sliding of the movable window sash 30 by cooperating with the lower guide rail 12C provided in the lower frame 12. The above-mentioned wood strip 2 is provided in a portion located between the middle vertical frame 15 and the right vertical frame 13 in the wood frame forming part 11A of the upper frame 11 so as to protrude toward the inner peripheral side on the depth surface as the inner peripheral side, and the upper edge of the panel 21 is sandwiched between the above-mentioned wood strip 2 and the inner protruding plate portion 59 provided in the metal frame forming part 11B of the upper frame 11 through the bonding material 6. The cover support member 11D is provided in a portion located between the middle vertical frame 15 and the left vertical frame 14 on the depth surface as the inner peripheral side, and the cover member 11E is provided between the above-mentioned cover support member 11D and the inner protruding plate portion 59 provided in the metal frame forming part 11B of the upper frame 11.

[0038] Similarly, by engaging the bent extension of the outer peripheral engaging plate portion 62 with the outer peripheral side engaging groove 43a, and engaging the bent extension of the inner peripheral depth plate portion 65 with the inner peripheral side engaging groove 41a, the metal frame forming portions 13B and 14B of the vertical frames 13 and 14 are maintained in a state of being attached to the wood frame forming portions 13A and 14A of the vertical frames 13 and 14. In this state, the outer peripheral main viewing plate portion 61 is in contact with the first outdoor main viewing surface 44, and the outer edge surfaces 13a and 14a facing the outside of the vertical frames 13 and 14 are provided along the main viewing direction at the outer peripheral side of the vertical frames 13 and 14 by the outer peripheral main viewing plate portion 61. The above-mentioned wood strip 2 is provided as the inner circumferential side depth surface in the wood frame forming part 13A of the right vertical frame 13 in a manner protruding toward the inner circumferential side, and the right edge of the panel 21 is sandwiched between the above-mentioned wood strip 2 and the inner circumferential main viewing plate part 64 provided in the metal frame forming part 13B of the right vertical frame 13 through the bonding material 6. In addition, the left edge of the panel 21 is sandwiched between the wood strip 2 installed on the middle vertical frame 15 and the metal frame forming part 15B of the middle vertical frame 15 through the bonding material 6. The cover support member 14D is provided as the inner circumferential side depth surface in the wood frame forming part 14A of the left vertical frame 14 in a manner protruding toward the inner circumferential side, and the cover member 14E is provided between the above-mentioned cover support member 14D and the inner circumferential main viewing plate part 64 provided in the metal frame forming part 14B of the left vertical frame 14. Furthermore, the inner peripheral side of the wood frame forming portion 15A of the middle vertical frame 15 is covered by a cover member 15E provided between the wood frame forming portion 15A and the metal frame forming portion 15B.

[0039] The upper frame 11 and the left and right vertical frames 13 and 14 are arranged in the opening b2 of the wall body B in a state where the outer edge surfaces 11a, 13a, 14a of the upper frame 11 and the outer surface b1 of the wall body B facing the outside are located on the same plane, and screw members S are screwed from the inner peripheral side of the upper frame 11 and the outer edge surfaces 13a and 14a of the vertical frames 13 and 14, thereby being attached to the wall body B. Waterproof cloths WP are provided on the outer edge surface 11a of the upper frame 11 and the outer edge surfaces 13a and 14a of the vertical frames 13 and 14, respectively, from the outer surface b1 of the wall body B. Thus, it is possible to prevent outdoor water from entering the room through the space between the wall body B and the upper frame 11 and between the wall B and the vertical frames 13 and 14. In particular, according to the upper frame 11 and the longitudinal frames 13 and 14 of the embodiment, since the outer surface b1 of the wall body B and the outer edge surfaces 11a, 13a, 14a are located on the same plane, that is, they are arranged side by side without any height difference, it is possible to set the waterproof cloth WP from the outer surface b1 of the wall body B to the outer edge surfaces 11a, 13a, 14a without pinholes or bends in the middle, thereby improving water tightness. Then, the outer wall material EM is arranged on the outdoor side from the outer surface b1 of the wall body B in a manner opposite to the outer edge surfaces 11a, 13a, 14a of the upper frame 11 and the longitudinal frames 13 and 14, and the sealing material ES is filled between the end surface of the outer wall material EM and the outer peripheral depth plate portions 53 and 63.

[0040] On the other hand, as for the lower frame 12, as described above, the portion from the portion protruding to the outdoor side to the portion arranged in the opening b2 of the wall body B is composed of the metal frame forming portion 12B, and the wood frame forming portion 12A is only provided at the portion closer to the indoor side than the middle vertical frame 15. Among them, the metal frame forming portion 12B of the lower frame 12 includes an outdoor side portion 22 and an indoor side portion 23, and the outdoor side portion 22 and the indoor side portion 23 are connected by two stages of bridge materials 24 and 25 formed of resin. Therefore, although the dimension of the metal frame forming portion 12B along the depth direction is formed large, the heat insulation of the lower frame 12 is not affected. The lower frame 12 is installed between the vertical frames 13 and 14 in the following manner, that is, the screw member is screwed into the screw hole 12a of the lower frame 12 through the vertical frames 13 and 14 in a state where the cut-out end surface of the lower frame 12 is opposite to the recessed portions 13F and 14F provided on the inner peripheral side of the vertical frames 13 and 14.

[0041] Here, if Figures 4 to 6 As shown, regarding the longitudinal frames 13 and 14, the proportion of the wood frame forming parts 13A and 14A in the depth direction is greater than the proportion of the metal frame forming parts 13B and 14B. Therefore, if the cut-out end face of the lower frame 12 is directly installed at a position opposite to the depth surface of the longitudinal frames 13 and 14, the metal frame forming part 12B of the lower frame 12 will be connected to the wood frame forming parts 13A and 14A of the longitudinal frames 13 and 14. Depending on the screwing state of the screw components, the metal frame forming part 12B as the cut-out end face in the lower frame 12 may cause deformation such as biting into the wood frame forming parts 13A and 14A of the longitudinal frames 13 and 14. Therefore, in the doors and windows of this embodiment, reinforcing plates 70 made of metal such as aluminum alloy are provided on the wood frame forming parts 13A and 14A of the longitudinal frames 13 and 14 to prevent the above-mentioned problems before they occur. More specifically, as Figure 7 to Figure 9 As shown in FIG. 1 , a flat reinforcing plate 70 is provided on the inner side of the longitudinal frames 13 and 14 at the portion from the metal frame forming portion 13B and 14B to the wood frame forming portion 13A and 14A. The reinforcing plate 70 can be provided at the portion corresponding to the screw hole 12a provided in the metal frame forming portion 12B of the lower frame 12. The reinforcing plate 70 does not need to be provided at the portion corresponding to the metal frame forming portion 12B of the lower frame 12 except for the screw hole 12a. Then, as shown in FIG. Figure 10 to Figure 12As shown, a sealing member 71 having a planar shape is disposed on the surface of the reinforcing plate 70, and in this state, the cut end surface of the lower frame 12 is brought into contact with the sealing member 71, and the screw member is passed through the vertical frames 13, 14 and screwed into the screw hole 12a. According to this door and window, since the reinforcing plate 70 is interposed between the metal frame forming part 12B of the lower frame 12 and the vertical frames 13, 14, even when the screw member is firmly screwed, the metal frame forming part 12B of the lower frame 12 will not bite into the wood frame forming parts 13A, 14A of the vertical frames 13, 14, and the watertightness between them will not be affected.

[0042] In the above embodiment, the reinforcing plate 70 is provided between the metal frame forming parts 13B and 14B of the vertical frames 13 and 14 and the wood frame forming parts 13A and 14A. However, for example, the reinforcing plate 70 may be provided. Figure 13 to Figure 17 As shown in the modified example, only the wood frame forming parts 13A and 14A of the vertical frames 13 and 14 are provided with reinforcing plates 72. That is, in the door and window of the modified example, first Fig.13 and Fig.14 As shown in FIG. 1 , a concave portion 73 corresponding to the thickness of the reinforcing plate 72 is pre-formed at the position where the reinforcing plate 72 is to be provided in the wood frame forming portion 13A, 14A of the longitudinal frame 13, 14. Then, as shown in FIG. Figure 15 to Figure 17 As shown in the figure, the reinforcing plate 72 is arranged in the recessed portion 73 to cover the wood frame forming portion 13A, 14A corresponding to the metal frame forming portion 12B of the lower frame 12, and the surface of the reinforcing plate 72 and the metal frame forming portions 13B, 14B of the longitudinal frames 13, 14 are arranged on the same plane. The position of setting the reinforcing plate 72 is the same as that of the embodiment. In this modified example, the metal frame forming portions 13B, 14B of the longitudinal frames 13, 14 or the reinforcing plate 72 is sandwiched between the metal frame forming portion 12B of the lower frame 12 and the longitudinal frames 13, 14, so that even when the screw member is firmly screwed, the metal frame forming portion 12B of the lower frame 12 will not bite into the wood frame forming portions 13A, 14A of the longitudinal frames 13, 14, and the watertightness between them will not be affected.

[0043] In addition, in the above embodiment, a single-leaf sliding window is exemplified, but it can also be applied to other types of windows. In addition, as the first forming part, a part formed of wood or the like is exemplified, and as the second forming part and the third forming part, a part formed of metal is exemplified, but the present invention is not limited to the above combination. For example, the first forming part may be formed of resin, and the second forming part may be formed of metal.

[0044] In addition, in the above embodiment, as the vertical frame, a vertical frame having a metal frame forming portion is exemplified, but a vertical frame formed only by a wood frame forming portion may be provided. Similarly, as the horizontal profile, a horizontal profile having a wood frame forming portion is exemplified, but a horizontal profile formed only by a metal frame forming portion may be provided.

[0045] As described above, the doors and windows of the present invention include a longitudinal profile and a transverse profile, wherein the longitudinal profile has a first formed portion, and the transverse profile has a second formed portion having a harderness than that of the first formed portion. At positions where the first formed portion and the second formed portion correspond to each other, the transverse profile is connected to the depth surface of the inner circumference of the longitudinal profile through its cut end surface. In the doors and windows, a reinforcing plate having a harderness than that of the first formed portion is sandwiched between the first formed portion and the second formed portion.

[0046] According to the present invention, since a reinforcing plate having a harderness than the first formed portion is sandwiched between the first formed portion of the longitudinal profile and the second formed portion of the transverse profile, even when a screw component is screwed into the longitudinal profile and the transverse profile, deformation such as the transverse profile biting into the longitudinal profile will not occur.

[0047] In addition, in the above-mentioned doors and windows of the present invention, a third formed portion having a harderness than that of the first formed portion is exposedly provided on the depth surface of the longitudinal profile serving as the inner circumferential side, the second formed portion of the transverse profile has a portion corresponding to both the first formed portion and the third formed portion, and the reinforcement plate is continuously arranged across the second formed portion and the portions corresponding to the first formed portion and the third formed portion.

[0048] According to the present invention, since the reinforcing plate is continuously provided from the first formed portion to the third formed portion, even when the vertical profile is used alone, it is advantageous in terms of strength.

[0049] In addition, in the above-mentioned doors and windows of the present invention, a third formed portion having a hardness greater than that of the first formed portion is exposedly provided on the depth surface of the longitudinal profile serving as the inner circumferential side, the second formed portion of the transverse profile has portions corresponding to both the first formed portion and the third formed portion, and the reinforcement plate is only sandwiched between portions corresponding to the second formed portion and the first formed portion.

[0050] According to the present invention, it is possible to prevent the transverse profile from biting into the longitudinal profile using the minimum necessary reinforcing plate.

[0051] In addition, in the above-mentioned door and window of the present invention, the reinforcing plate and the second molded portion are formed of the same material.

[0052] According to the present invention, the second molded portion does not bite into the reinforcing plate.
