Description

TECHNICAL FIELD

[0001] The present application relates to a door and window having a frame material constituting a frame, a surface material provided on the inner peripheral side of the frame, and an attachment member provided between the frame material and the surface material. BACKGROUND

[0002] On a window provided on a building, a surface material such as glass is sometimes provided on the inner peripheral side of the frame. An attachment member is sometimes provided between the frame material constituting the frame and the surface material according to the specifications. As shown in Patent Document 1, the attachment member is effective for a combination window and a segment window, which require different kinds of windows to be provided in a composite manner on the frame material in the same section.

[0003] Patent Document 1: Japanese Realization Publication No. Sho 61-020773 SUMMARY

[0004] On the other hand, the above-described attachment member is restricted by screwing with respect to the frame material. Therefore, the number of components increases and the number of processing / assembly processes increases. Also, since the frame material is fixed by screwing, there is a concern that rainwater will penetrate the screw hole when the screw comes loose or the like, and the main body will leak. Furthermore, even if a fixing means other than a screw is used, the fixing strength must be ensured.

[0005] The present application has been made in view of the above-described problems, and aims to provide a door and window that can reduce the number of components and the number of assembly processes and obtain sufficient fixing strength.

[0006] To solve the above-described problems and achieve the object, the door and window of the present application includes: a frame material constituting a frame; a surface material provided on the inner peripheral side of the frame; and an attachment member provided between the frame material and the surface material, the frame material having a first engaged portion on one side in the depth direction and a second engaged portion on the other side, the attachment member having a first engaging portion engaged with the first engaged portion and a second engaging portion engaged with the second engaged portion, the second engaging portion and the second engaged portion being located on the inner peripheral side than the first engaging portion and the first engaged portion, the first engaged portion allowing the first engaging portion to be unable to move toward the one side, and the second engaged portion allowing the second engaging portion to be unable to move toward the inner peripheral side by snap-fit engagement.

[0007] In the door and window of the present application, since the second engaging portion of the attachment member is engaged with the second engaged portion by snap-fit, the number of components and the number of assembly processes can be reduced without a screw. Also, since the second engaging portion and the second engaged portion are located on the inner peripheral side than the first engaging portion and the first engaged portion, the distance from the center of the surface material can be reduced, and the torque acting in the direction of the snap-fit loosening can be suppressed, thereby obtaining sufficient fixing strength.

[0059] Hereinafter, embodiments of the doors and windows of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, the following embodiments do not constitute a limitation on the invention.

[0060] Figure 1 This is an overall view of the door and window 10 as an embodiment of the present invention, viewed from the interior side. Figure 2 yes Figure 1 Longitudinal section view along arrow II-II. Figure 3 yes Figure 1 Cross-sectional view along arrow III-III. Figure 4 yes Figure 1 Cross-sectional view along arrow IV-IV. The left and right markings in the following description refer to the view from the interior side, i.e., with... Figure 1 Based on.

[0061] In the door and window 10, the left vertical frame 12, the right vertical frame 14, and the upper frame 16 and lower frame 18 arranged between the vertical frames 12 and 14 are assembled into a four-sided frame, and then a crossbeam 20 is arranged between the vertical frames 12 and 14.

[0062] In this application, the depth direction refers to the indoor / outdoor direction of the door / window 10. Figure 1 (Vertical direction of the paper surface). The depth surface refers to the surface extending along the depth direction. The main viewing direction refers to the direction orthogonal to the depth direction. For vertical frames (e.g., 12) with longer vertical dimensions, it refers to the left-right direction orthogonal to its length direction. For upper frames (e.g., 16) with longer left-right dimensions, it refers to the vertical direction orthogonal to its length direction. The main viewing surface refers to the surface along the main viewing direction.

[0063] In addition to the frame whose outer contour is formed by the longitudinal frames 12, 14, 16, and 18, the door / window 10 can also be considered as having two smaller frames contained within it. These two frames refer to a first frame 24a formed by the left longitudinal frame 12, the right longitudinal frame 14, the crossbeam 20, and the lower frame 18, and a second frame 24b formed by the left longitudinal frame 12, the right longitudinal frame 14, the 16, and the crossbeam 20. The first frame 24a and the second frame 24b, arranged vertically, form a segmented window. Alternatively, the door / window 10 can also be a connected window with longitudinal ribs between the 16 and 18, or a segmented window with crossbeams 20 and longitudinal ribs. The door / window using this invention is not limited to connected windows, segmented windows, or segmented windows, but can be applied to doors and windows where the face material is held in place relative to the frame material using fasteners.

[0064] A FIX window is formed by the face material 26 on the first frame 24a. A door and window leaf 28 is provided on the second frame 24b, which is supported by a frame around the periphery. The door and window leaf 28 is formed as a vertically sliding window, which is opened in a manner of protruding to the outside by an opening and closing mechanism provided on the second frame 24b. The face material 26 is, for example, a laminated glass.

[0065] The frame materials constituting the vertical frames 12, 14, the upper frame 16, the lower frame 18, and the cross beam 20 are extruded profiles made of metal such as aluminum alloy or resin. In the case of using resin for these frame materials, a metal reinforcing member can be appropriately provided. The vertical frames 12, 14 are made of frame materials having the same cross-sectional shape. The inner peripheral side surface of the upper frame 16 and the lower side surface of the cross beam 20 are the same shape.

[0066] As shown in FIG. 1, the door and window leaf 28 is directly provided on the vertical frames 12, 14 by means of the opening and closing mechanisms 28a, 28b. The face material 26 is attached to the cross beam 20 by means of the attachment member 32 and attached to the vertical frames 12, 14 by means of the attachment member 34 because the shape of the periphery thereof is different from that of the door and window leaf 28. Figure 4

[0067] The attachment members 32, 34 are basically extruded profiles made of metal such as aluminum alloy. By using such attachment members 32, 34, various face materials and door and window leaves can be attached to the frame materials constituting a French window or a casement window. The attachment members 32, 34 can also be formed of a resin material.

[0068] Hereinafter, the first frame 24a, the attachment members 32, 34 attached to the inner peripheral surface of the first frame 24a, and the portions associated therewith will be mainly described. Since the first frame 24a forms one frame, the cross beam 20 will also be referred to as the upper frame 20 for convenience of description. That is, the first frame 24a is a frame formed of the left vertical frame 12, the right vertical frame 14, the upper frame 20, and the lower frame 18, which constitute a four-sided frame.

[0069] Figure 5 FIG. 6 is an enlarged longitudinal sectional view of the upper frame 20, the attachment member 32, and the face material 26. The face material 26 has a plurality of glasses 26a and a seal 26b provided around the periphery of the main surface of each glass 26a on the indoor side and the outdoor side. In the face material 26, the seal 26b on the indoor side is supported by a partition wall 46 to be described later, and the seal 26b on the outdoor side is supported by a press edge 45. The press edge 45 has a main surface piece 45a for supporting the seal 26b on the outdoor side, and a depth piece 45b extending from the outer peripheral end of the main surface piece 45a toward the indoor side. A recess 45c is formed at the outdoor side intersection of the main surface piece 45a and the depth piece 45b.

[0070] ​A face material outer periphery space 30 is formed between the face material 26 and the attachment piece 32. A first fin 20b that protrudes toward the inner periphery side is provided from an inner periphery side deep surface 20a of the upper frame 20. A first bag-shaped recessed portion 37 that opens toward the inner periphery side is formed at an outdoor side end portion of the inner periphery side deep surface 20a. A protrusion 20c that is the outdoor side end portion of the first bag-shaped recessed portion 37 is also an inner periphery side end portion of the outdoor side main surface of the upper frame 20, and protrudes slightly toward the outdoor side, guides water that has fallen from above toward the outdoor side, and prevents the water from permeating into the inside of the first bag-shaped recessed portion 37. A second bag-shaped recessed portion 35 that opens toward the outdoor side is formed in the vicinity of the front end of the first fin 20b.

[0071] By Figure 5 It is understood that the first bag-shaped recessed portion 37 is located more toward the outdoor side (one side) than the second bag-shaped recessed portion 35 in the depth direction and is located more toward the outer periphery side. Conversely, the second bag-shaped recessed portion 35 is located more toward the indoor side (the other side) than the first bag-shaped recessed portion 37 in the depth direction and is located more toward the inner periphery side. Furthermore, if the face material 26 is taken as a reference, the first bag-shaped recessed portion 37 is provided at a position that is more toward the outdoor side than the face material 26 and is more toward the outer periphery side than the outer periphery edge 26c. Similarly, the second bag-shaped recessed portion 35 is provided at a position that is more toward the indoor side than the face material 26 and is more toward the inner periphery side than the outer periphery edge 26c.

[0072] As described above, the inner periphery side surface of the upper frame 16 and the lower surface of the cross member 20 (upper frame 20) are the same shape, and the upper frame 16 is also provided with the first fin 20b and the bag-shaped recessed portions 35, 37. A waterproof member 38 (see Figure 2 ) is provided in the first bag-shaped recessed portion 37 of the upper frame 16. The waterproof member 38 guides rainwater that has leaked from above toward the outdoor side, so that the water does not easily drip onto the door and window leaf 28. A seal member 36 (see Figure 2 ) is provided in the second bag-shaped recessed portion 35 of the upper frame 16. The seal member 36 is in a watertight structure with the door and window leaf 28. The bag-shaped recessed portions 35, 37 of the upper frame 16 and the cross member 20 are the same shape. Therefore, the first bag-shaped recessed portion 37 of the cross member 20 is a shape in which the waterproof member 38 can be provided, and the second bag-shaped recessed portion 35 of the cross member 20 is a shape in which the seal member 36 can be provided.

[0073] The attachment piece 32 can be divided into an outdoor side portion 32a and an indoor side portion 32b, in which the outdoor side portion 32a has a smaller width in the main surface direction, is disposed at the outer periphery side of the face material 26, and the indoor side portion 32b has a larger width in the main surface direction, is located more toward the indoor side than the outdoor side portion 32a and the face material 26. Here, the outdoor side portion 32a and the indoor side portion 32b are conceptually divided for convenience of explanation.

[0074] In this embodiment, the depth dimension of the outdoor side portion 32a and the indoor side portion 32b is substantially equal. In this embodiment, the depth dimension of the indoor side portion 32b is substantially equal to the front view dimension. The outdoor side portion 32a is a portion that is not exposed to the interior. The outdoor side portion 32a is a portion that supports the face material 26 together with the presser 45. In the indoor side portion 32b, the indoor wall 52, which will be described later, is exposed to the interior. Between the face material 26 and the outdoor side portion 32a of the attachment 32, the face material peripheral space 30 is formed.

[0075] The outdoor side portion 32a includes the face contact portion 40, the inclined wall 42, the tab 44, the partition wall 46, the small wall 48, and the first engaging portion 50. The face contact portion 40 is in contact with the inner peripheral side depth surface 20a, and the depth direction length accounts for a large portion of the outdoor side portion 32a. The partition wall 46 is connected to the indoor side end portion of the face contact portion 40 via the inclined wall 42, and extends in the front view direction. The partition wall 46 supports the glass 26a via the seal 26b together with the front view surface piece 45a of the presser 45. The tab 44 protrudes toward the outdoor side from the connecting portion of the inclined wall 42 and the partition wall 46. The small wall 48 slightly protrudes toward the inner peripheral side from the outdoor side end portion of the attachment 32. The first engaging portion 50 slightly protrudes toward the outer peripheral side from the outdoor side end portion of the attachment 32. The first engaging portion 50 will be described further later.

[0076] The front end 45ba of the depth surface piece 45b in the presser 45 is bent slightly toward the inner peripheral side, into the space between the tab 44 and the inclined wall 42, and engages the front end of the tab 44. The inclined wall 42 is inclined in a manner that approaches the outer peripheral side as it goes from the indoor side toward the outdoor side. The inner peripheral side end portion of the small wall 48 is bent toward the indoor side and engages the recess 45c of the presser 45.

[0077] The indoor side portion 32b has the indoor wall 52, the second fin 54, and the second engaging portion 56. The indoor wall 52 extends from the inner peripheral side end portion of the partition wall 46 toward the indoor side in the depth direction by an appropriate length. The second fin 54 protrudes from a portion of the indoor wall 52 near the second engaging portion 56 toward the outer peripheral side, and the front end abuts the inner peripheral side depth surface 20a of the upper frame 20. The second engaging portion 56 protrudes from the indoor side end portion of the indoor wall 52 toward the outer peripheral side. The second engaging portion 56 will be described further later.

[0078] Figure 6 is an enlarged longitudinal sectional view of the upper frame 20, the first engaging portion 50, and the surrounding area. As Figure 6As shown, the first pocket recess 37 is formed by three walls, a bottom wall 37a, an outdoor side wall (first engaged portion) 37b, and an indoor side wall 37c. Further, the outdoor side wall 37b has a small protrusion (first engaged portion) 37ba protruding toward the indoor side, and the indoor side wall 37c has a small protrusion 37ca protruding toward the outdoor side. The protrusions 37ba, 37ca protrude in an opposing manner, narrowing the opening of the first pocket recess 37.

[0079] The first pocket recess 37 can be provided with a waterproof member 38 (see Figure 2 In this embodiment, the outdoor side wall 37b is used as the first engaged portion 50. That is, the outdoor side wall 37b forms an inner circumferential protrusion protruding toward the inner circumferential side, and has the protrusion 37ba protruding toward the indoor side as the first engaged protrusion, and this shape has an engaged function.

[0080] The first engaged portion 50 has an outer circumferential protrusion 50a protruding toward the outer circumferential side, and a first engaged protrusion 50b protruding from the outer circumferential protrusion 50a toward the outdoor side. The first engaged protrusion 50b is slightly inclined toward the outer circumferential side. The first engaged portion 50 is engaged with the outdoor side wall 37b in such a manner that the first engaged protrusion 50b is located on the outer circumferential side of the protrusion 37ba, and does not fall toward the inner circumferential side. Further, the tip of the protrusion 37ba is in abutment with the outer circumferential protrusion 50a, so that the first engaged portion 50 cannot move toward the outdoor side. The first engaged portion 50 can also be such that it cannot move toward the outdoor side by being in abutment with the outdoor side wall 37b.

[0081] Figure 7 is an enlarged longitudinal sectional view of the second engaged portion 56 and its surroundings. As shown, Figure 7 The second pocket recess 35 is formed by three walls, a bottom wall 35a, an inner circumferential side wall (second engaged portion) 35b, and an outer circumferential side wall 35c. Further, the inner circumferential side wall 35b has a small protrusion 35ba protruding toward the outer circumferential side, and the outer circumferential side wall 35c has a small protrusion 35ca protruding toward the inner circumferential side. The protrusions 35ba, 35ca protrude in an opposing manner, narrowing the opening of the second pocket recess 35. The bottom wall 35a is a portion of the first fin 20b.

[0082] The second pocket recess 35 can be provided with a sealing member 36 (see Figure 2 In this embodiment, the inner circumferential side wall 35b is used as the second engaged portion 56. That is, the inner circumferential side wall 35b has the protrusion 35ba protruding toward the outer circumferential side as the second engaged protrusion, and this shape has an engaged function.

[0083] The second engaging portion 56 has a base protrusion 56a protruding from the end portion of the indoor wall 52 toward the outer peripheral side, a second engaging protrusion 56b protruding from the front end of the base protrusion 56a toward the indoor side, and a convex portion 56c slightly protruding from the base end of the base protrusion 56a toward the indoor side. In the second engaging protrusion 56b, an angular portion 56ba protruding further toward the outer peripheral side from the front end is provided. The angular portion 56ba is slightly inclined toward the indoor side.

[0084] The second engaging portion 56 engages with the inner peripheral side wall 35b in a manner that the second engaging protrusion 56b is positioned on the outer peripheral side of the protrusion 35ba of the inner peripheral side wall 35b without falling toward the inner peripheral side. The second engaging portion 56 is provided at the front end of the base protrusion 56a, and thus can be displaced in the depth direction due to elastic inclination of the base protrusion 56a caused by external force. The second fin 54 is slightly spaced from the second engaging portion 56, and thus does not interfere with the displacement of the second engaging portion 56 toward the outdoor side.

[0085] The second fin 54 is positioned near the second engaging portion 56, and forms a rectangle with a small depth dimension with the first fin 20b, the second fin 54, the inner peripheral side depth surface 20a, and the indoor wall 52. The first fin 20b and the second fin 54 face each other and extend in opposite directions, and support each other in the front direction at a close position to maintain stability.

[0086] The base protrusion 56a is spaced from the inner peripheral side wall 35b by the protruding amount of the convex portion 56c, and thus does not interfere with each other even if the base protrusion 56a is inclined toward the indoor side. Thus, the second engaging protrusion 56b has a displacement allowance with respect to the indoor side, and thus can be reliably engaged with the inner peripheral side wall 35b. In addition, as described above, the attachment member 32 is an aluminum member having a suitable strength, and the base protrusion 56a has a suitable length, and thus can be elastically displaced as appropriate. Of course, the attachment member 32 can be deformed when the attachment member 32 is a resin material. The second engaging protrusion 56b plugs the opening of the second bag-shaped recess 35.

[0087] The front end of the convex portion 56c abuts against the end surface of the inner peripheral side wall 35b, and thus the second engaging portion 56 cannot be displaced toward the indoor side. Although the convex portion 56c for restricting the displacement toward the indoor side is provided in a portion of the second engaging portion 56 or near the portion, and cooperates with the second engaging protrusion 56b to maintain stability, a member corresponding to the convex portion 56c for restricting the displacement toward the indoor side can be provided at a different position according to design conditions.

[0088] Figure 8 is a schematic longitudinal sectional view showing the assembly of the attachment member 32 to the upper frame 20. As shown in Figure 8 When the attachment member 32 is assembled to the upper frame 20, first, the first engaging protrusion 50b (see Figure 6) is inserted into the first bag-shaped recess 37, and is disposed on the outer peripheral side of the protrusion 37ba. At this time, as shown by the solid line in FIG. 6, the attachment member 32 is tilted, and the second engaging portion 56 is in a non-engaged state with the inner peripheral side wall 35b, which is located on the inner peripheral side of the inner peripheral side wall 35b. Figure 8

[0089] As shown in FIG. 7, the outer peripheral protrusion 50a and the first engaging protrusion 50b are formed to be slightly narrower than the opening width of the first bag-shaped recess 37, and are easily inserted into the first bag-shaped recess 37. In particular, since the first engaging protrusion 50b is formed in a slightly inclined shape toward the outer peripheral side, it is easily inserted obliquely between the bottom wall 37a and the protrusion 37ba. Figure 6

[0090] The first engaging protrusion 50b has a slight gap with the bottom wall 37a and the protrusion 37ba, respectively, and has a certain amount of movement in the front view direction. Therefore, the first bag-shaped recess 37 does not restrict the attachment member 32, but supports it so that it can rotate with the first engaging portion 50 as the center of rotation C in the non-engaged state before the second engaging portion 56 is engaged.

[0091] Thus, once the attachment member 32 is rotated about the center of rotation C in the counterclockwise direction of FIG. 6, the front end of the corner portion 56ba of the second engaging portion 56 comes into abutment with the inner peripheral side wall 35b. Since the corner portion 56ba is subjected to a reaction force from the inner peripheral side wall 35b toward the room exterior side, the base protrusion 56a is elastically deformed, and the second engaging protrusion 56b and the corner portion 56ba are temporarily displaced toward the room exterior side. Figure 8 Since the corner portion 56ba is formed in a slightly inclined shape toward the room interior side, the second engaging protrusion 56b is temporarily displaced slightly larger toward the room exterior side. Along with the rotation of the attachment member 32 in the counterclockwise direction, the corner portion 56ba is guided while sliding in almost surface contact with the front surface of the protrusion 35ba, and then passes over the protrusion 35ba. Since the reaction force on the second engaging protrusion 56b disappears, the base protrusion 56a returns to the original position, and the second engaging protrusion 56b and the corner portion 56ba enter the gap between the protrusion 35ba and the protrusion 35ca. Thus, the attachment member 32 is installed to the prescribed position as shown by the dotted line in FIG. 6.

[0092] Figure 8

[0093] ​​​​Thus, the second engaging portion 56 is engaged with the inner peripheral wall 35b in a snap-fit manner. Therefore, when the attachment member 32 is assembled to the upper frame 20, it is possible to reduce the number of components and the number of assembly processes without using a screw or a screwdriver. Here, when the attachment member 32 is assembled, it is also possible to gently hit with a hammer or the like depending on the situation. Further, since the attachment member 32 of the door and window 10 is fixed by the snap-fit without using a screw, it is not necessary to worry about loosening due to aging. Since a screw is not used, it is not necessary to worry about water leakage through a screw hole on the upper frame 20 as an installation target.

[0094] When the attachment member 32 is assembled to the upper frame 20, for the outdoor side, the protrusion 37ba (see Figure 6 ) abuts against the outer peripheral protruding portion 50a, and thus the movement is restricted, and for the indoor side, the inner peripheral wall 35b (see Figure 7 ) abuts against the convex portion 56c, and thus the movement is restricted. Further, for the outer peripheral side, the inner peripheral side deep surface 20a abuts against the surface contact portion 40 and the second fin 54, and thus the movement is restricted. Further, for the inner peripheral side, at the outdoor side end portion, the first engaging protrusion 50b is engaged with the protrusion 37ba, and at the indoor side end portion, the second engaging protrusion 56b is engaged with the inner peripheral wall 35b, and thus the movement is restricted. Thus, the attachment member 32 is restricted in movement with respect to four directions, and is stable.

[0095] Figure 9 is a schematic longitudinal sectional view of a state in which an external force Fl acts on the surface material 26 toward the indoor side. Figure 9 、 Figure 10 In the middle, the deformation of the surface material 26 is shown in an exaggerated manner. As shown in Figure 9 , there are cases in which an external force Fl acts on the surface material 26 from the outdoor side toward the indoor side. The external force Fl is mainly a force generated by wind. For modeling, it is assumed that the external force Fl is concentratedly applied to the center of the surface material 26.

[0096] If the external force Fl acts, a counterclockwise torque Ml acts between the upper frame 20 and the attachment member 32. This torque Ml is mainly supported by the first engaging portion 50 (see Figure 6 ) through the protrusion 37ba. Due to the support of the protrusion 37ba, the first engaging protrusion 50b is more strongly abutted against the protrusion 37ba, and it is not necessary to worry about falling from the first bag-shaped recess 37. If the distance between the point of application of the external force Fl and the first engaging portion 50 is LI, the torque Ml acting on the portion of the first engaging portion 50 due to the external force Fl is expressed as Ml = Fl x LI.

[0097] Figure 10 is a schematic longitudinal sectional view of a state in which an external force F2 acts on the surface material 26 toward the outdoor side. As shown in Figure 10As shown, an external force F2 acts on the face material 26 from the indoor side toward the outdoor side at times. The external force F2 is, for example, a force generated by a Karman vortex caused by wind. For modeling, it is assumed that the external force F2 acts centrally on the face material 26.

[0098] If the external force F2 acts, a clockwise torque M2 acts between the upper frame 20 and the attachment member 32. This torque M2 is mainly supported by the second engaging portion 56 (see Figure 7 ) via the inner peripheral wall 35b. Due to the support of the inner peripheral wall 35b, a force is applied in a direction in which the second engaging protrusion 56b is released from the inner peripheral wall 35b. If the distance between the point of action of the external force F2 and the second engaging portion 56 is L2, the torque M2 acting on the portion of the second engaging portion 56 by the external force F2 is expressed as M2 = F2 x L2.

[0099] On the other hand, since the second engaging portion 56 and the inner peripheral wall 35b as the second engaged portion are located at the inner peripheral side than the first engaging portion 50 and the outdoor side wall 37b as the first engaged portion, L2 < LI. Therefore, if the external force Fl and the external force F2 are appropriately the same size, the torque M2 acting on the second engaging portion 56 is suppressed to be smaller than the torque Ml acting on the first engaging portion 50. Therefore, although the torque M2 acts in a direction in which the second engaging portion 56 is released from the inner peripheral wall 35b, since the torque M2 is small, the second engaging portion 56 can be prevented from being released. Thus, the attachment member 32 can obtain sufficient fixing strength without using a fastener such as a screw.

[0100] In addition, since the first engaging portion 50 and the first bag-shaped recess 37 are provided at the outer peripheral side than the outer peripheral edge 26c of the face material 26, and the second engaging portion 56 and the second bag-shaped recess 35 are provided at the inner peripheral side than the outer peripheral edge 26c, the second engaging portion 56 is reliably located at the inner peripheral side than the first engaging portion 50. Since the first bag-shaped recess 37 and the first engaging portion 50 are provided at the outer peripheral side than the outer peripheral edge 26c, there is no hindrance in assembling the face material 26 to the attachment member 32. Since the first bag-shaped recess 37 is provided at the outer peripheral side than the outer peripheral edge 26c, it is positionally suitable for providing the waterproof member 38. Since the second bag-shaped recess 35 is provided at the inner peripheral side than the outer peripheral edge 26c, it is positionally suitable for providing the sealing member 36.

[0101] Figure 11 is an enlarged cross-sectional view of the left longitudinal frame 12, the attachment member 34, and the face material 26. In addition, the right longitudinal frame 14 and the attachment member 34 and their assembled configuration are left-right symmetrical to those shown in Figure 11 , and thus the illustration and description thereof are omitted.

[0102] As shown in Figure 11As shown, in the face material 26, the seal member 26b on the indoor side is supported by the partition wall 46, and the seal member 26b on the outdoor side is supported by the press edge 45. The press edge 45 is in contact with the inner peripheral side of the inner peripheral side deep face 12a of the vertical frame 12. Figure 5 As shown, the same space as the space between the face material 26 and the attachment member 32 (see FIG. 1) is formed between the face material 26 and the attachment member 34. That is, the face material peripheral space 30 is formed so as to communicate at the entire periphery of the face material 26. Figure 5

[0103] A first fin 12b protruding toward the inner peripheral side is provided from the inner peripheral side deep face 12a of the vertical frame 12. The first fin 12b is the same shape as the first fin 20b in the upper frame 20, and a second bag-shaped recess 35 is formed in the vicinity of the front end thereof, which is open on the outdoor side. The second bag-shaped recess 35 is the same as the second bag-shaped recess 35 shown in FIG. 1. Figure 5 Figure 7 As shown, the same space as the space between the face material 26 and the attachment member 32 (see FIG. 1) is formed between the face material 26 and the attachment member 34. That is, the face material peripheral space 30 is formed so as to communicate at the entire periphery of the face material 26.

[0104] The attachment member 34 is provided with the same face contact portion 40, inclined wall 42, small piece 44, partition wall 46, indoor wall 52, second fin 54, and second engagement portion 56 as the attachment member 32. In addition, these constituent elements in the attachment member 34 differ somewhat in size from the constituent elements in the attachment member 32 in a strict sense, but the same reference numerals are assigned for easy understanding, and detailed description is omitted.

[0105] The attachment member 34 is provided with a small wall 62. The small wall 62 corresponds to the small wall 48 in the attachment member 32, but the front view dimension is shorter than that of the small wall 48. Instead of the first engagement portion 50 in the attachment member 32, the attachment member 34 is provided with a first engagement portion 64. The first engagement portion 64 and the first engaged portion 60 will be described later.

[0106] The attachment member 34 is provided with a partition wall 66. The partition wall 66 protrudes from the indoor side end of the small piece 44 toward the outer peripheral side, and the end thereof is in contact with the inner peripheral side deep face 12a. The partition wall 66 and the partition wall 46 extend in the front view direction in substantially the same straight line. The partition wall 66 partitions a first space 68 on the outdoor side up to the inclined wall 42 and a second space 70 on the indoor side up to the second fin 54. In addition, the second fin 54 partitions a second space 70 on the outdoor side and an auxiliary space 72 on the indoor side up to the first fin 12b. The first space 68, the second space 70, and the auxiliary space 72 communicate in the up-down direction, and each of the lower end portions thereof communicates with the outside air. The face material peripheral space 30 also communicates with the outside air at the lower end portion.

[0107] ​​The first space 68 and the second space 70 are spaces in which the outside air is communicated to become equal pressure spaces. Although it is generally considered that rainwater outside the room penetrates along the surface contact portion 40 between the inner peripheral side depth surface 12a and the attachment member 34, since the surface contact portion 40 is appropriately long in the depth direction, the rainwater hardly reaches the first space 68. Further, the first space 68 does not have a pressure difference from the outside air and does not have a function of sucking water since it is the outside air pressure. Even if water reaches the first space 68, since the second space 70 and the first space 68 are equal pressure, there is no pressure difference, and there is no function of the second space 70 sucking water from the first space 68, and water hardly reaches the second space 70. The second space 70 is located on the room inner side, but ensures an appropriately large area and is easily maintained at the outside air pressure.

[0108] Figure 12 is an enlarged cross-sectional view of the longitudinal frame 12, the first engaging portion 64, and the periphery thereof. As shown in Figure 12 , the first engaged portion 60 protrudes from the inner peripheral side depth surface 12a of the longitudinal frame 12 toward the inner peripheral side. Further, the first engaged portion 60 has a small protrusion 60a protruding toward the room inner side at the front end portion.

[0109] The first engaging portion 64 has a small first engaging protrusion 64a protruding toward the room outer side, and a small recessed portion 64b recessed toward the room inner side between the first engaging protrusion 64a and the small wall 62. The first engaging protrusion 64a is the room outer side end portion of the surface contact portion 40.

[0110] The first engaging portion 64 is engaged with the first engaged portion 60 in such a manner that the first engaging protrusion 64a is located on the outer peripheral side of the protrusion 60a without falling toward the inner peripheral side. Further, the front end of the protrusion 60a abuts against the recessed portion 64b so that the first engaging portion 64 cannot move toward the room outer side. The first engaging portion 64 can also be such that the first engaging protrusion 64a cannot move toward the room outer side by abutting against the first engaged portion 60.

[0111] Such an attachment member 34 is attached to the longitudinal frame 12 by causing the first engaging portion 64 and the second engaging portion 56 to function similarly to the first engaging portion 50 and the second engaging portion 56 in the above-described attachment member 32. The attachment member 34 does not require a screw at the time of assembly, and can reduce the number of parts and the number of assembly processes.

[0112] At the time of attachment of the attachment member 34 to the longitudinal frame 12, which is omitted from the drawing, first, the first engaging protrusion 64a of the first engaging portion 64 is located on the room outer side of the protrusion 60a in advance, and the attachment member 34 is rotated with the portion as a center of rotation, and the second engaging portion 56 is inserted into the second bag-shaped recessed portion 35. This is substantially the same as the assembly method of the attachment member 32 described with reference to Figure 8 .

[0113] The second engaging portion 56 in the attachment 34 is located on the indoor side and inner peripheral side relative to the first engaging portion 64, which can suppress the action as follows. Figure 10 The torque M2 generated by the external force F2 from the indoor side toward the outdoor side, as shown, provides sufficient fixation strength.

[0114] Furthermore, in the above embodiment, it is assumed that the first engaging portions 50 and 64 are located on the outdoor side and outer periphery, and the second engaging portion 56 is located on the indoor side and inner periphery. However, the indoor and outdoor sides can also be interchanged. That is to say, the upper frame 16 with the same structure as the crossbeam 20 on the inner periphery side (see...) Figure 2 The shape corresponds to the outward-opening door / window sash 28. However, if the door / window sash 28 is an inward-opening structure, the relative positions of the second pocket-shaped recess 35 and the first pocket-shaped recess 37 are reversed. Therefore, the relative positions of the second pocket-shaped recess 35 and the first pocket-shaped recess 37 with respect to the crossbeam 20 are also reversed. The first engaging portions 50 and 64 are located on the indoor side and the outer periphery, while the second engaging portion 56 is located on the outdoor side and the inner periphery. In this case, the same effect as in the above embodiment can be obtained.

[0115] The door and window of the present invention includes: a frame material forming a frame body; a face material disposed on the inner peripheral side of the frame body; and an attachment material disposed between the frame material and the face material. The frame material has a first engaging portion on one side and a second engaging portion on the other side in the depth direction. The attachment material has a first engaging portion engaging with the first engaging portion and a second engaging portion engaging with the second engaging portion. The second engaging portion and the second engaging portion are located on the inner peripheral side of the frame body, respectively. The first engaging portion prevents the first engaging portion from moving to the first side, and the second engaging portion prevents the second engaging portion from moving on the inner peripheral side by means of a snap-fit ​​engagement.

[0116] In this type of door and window connector, the second engaging part engages with the second engaged part via a snap-fit ​​mechanism, eliminating the need for screws and reducing the number of components and assembly steps. Furthermore, because the second engaging part and the second engaged part are located on the inner periphery compared to the first engaging part and the first engaged part, the distance from the center of the surface material is reduced, thereby suppressing the torque acting in the direction of loosening of the snap-fit ​​and achieving sufficient fixing strength.

[0117] In the doors and windows of the present invention, the first engaging portion is supported such that when the second engaging portion is in a non-engaged state relative to the second engaging portion, the attachment can rotate around the first engaging portion. This makes the assembly of the attachment easier.

[0118] In the door and window of the present application, the first engaged portion can have an inner peripheral protruding portion protruding toward the inner peripheral side, and a first engaged protrusion protruding from the inner peripheral protruding portion toward the other side. The first engaging portion can have an outer peripheral protruding portion protruding toward the outer peripheral side, and a first engaging protrusion protruding from the outer peripheral protruding portion toward the one side and positioned on the outer peripheral side of the first engaged protrusion. Thus, the first engaging portion and the first engaged portion are reliably engaged, and movement toward the inner peripheral side is restricted.

[0119] In the door and window of the present application, the second engaged portion can have a second engaged protrusion protruding toward the outer peripheral side. The second engaging portion can have a second engaging protrusion positioned on the outer peripheral side of the second engaged protrusion and elastically displaceable in the depth direction. Thus, the second engaging portion and the second engaged portion are reliably engaged and become a snap-fit structure.

[0120] In the door and window of the present application, the first engaged portion can be a part of a first bag-shaped recess portion in which a waterproof member can be provided. When a door and window sash or the like is installed without providing an attaching member on a frame, a waterproof member providing portion needs to be additionally provided. However, according to the door and window of the present application, it is not necessary to additionally provide a waterproof member providing portion, and this is very desirable.

[0121] In the door and window of the present application, the second engaged portion can be a part of a second bag-shaped recess portion in which a sealing member can be provided. When a door and window sash or the like is installed without providing an attaching member on a frame, a sealing member providing portion needs to be additionally provided. However, according to the door and window of the present application, it is not necessary to additionally provide a sealing member providing portion, and this is very desirable.

[0122] In the door and window of the present application, the first engaging portion and the first engaged portion can be provided at the outer peripheral side than the outer peripheral edge of the face material, and the second engaging portion and the second engaged portion can be provided at the inner peripheral side than the outer peripheral edge of the face material. Thus, the second engaging portion and the second engaged portion are reliably positioned at the inner peripheral side than the first engaging portion and the first engaged portion, and the distance from the center portion of the face material can be reduced.

[0123] In the door and window of the present application, the frame can have a first fin protruding from an inner peripheral side depth surface wall toward the inner peripheral side, the attaching member can have a second fin protruding from the vicinity of the second engaging portion toward the outer peripheral side and abutting against the inner peripheral side depth surface wall of the frame, and the second engaged portion can be provided at the first fin. The first fin and the second fin complement each other and support each other, and the surrounding portion of the second engaging portion and the second engaged portion is kept stable.

[0124] Of course, the present application is not limited to the above-described embodiments, and can be freely changed within the scope of the gist of the present application.
