Hereinafter, preferred embodiments of the door and window of the present invention will be described in detail with reference to the drawings.

1 to 5 are views showing a door and window according to an embodiment of the present invention. The door and window exemplified herein has an opening frame 10 and a door leaf (door sash) 20 that is disposed to be openable and closable with respect to the opening frame 10, and the outdoor (second space) and the room are closed by closing the door leaf 20 with respect to the opening frame 10. The first space) is separated between. The opening frame 10 is configured by combining the upper frame 11, the lower frame 12, and the left and right vertical frames 13 into a surrounding frame, and is mounted along an opening (not shown) provided on a wall of the building. The door leaf 20 is configured by attaching the upper frame 22, the lower frame 23, and the left and right vertical frames 24 to the periphery of the glass plate 21 having a rectangular shape. When the door leaf 20 is viewed from the outdoor side, a hinge 1 is provided between the vertical frame 24 located on the right side and the vertical frame 13, and can be opened to the outside by the hinge 1 and opened. 2 and 3, the door leaf 20 is configured such that its dimension along the depth direction is substantially one-half of that of the opening frame 10, and is disposed in a region on the outdoor side of the opening frame 10 when closed.

Here, the depth direction means a direction along the depth of the door and window as indicated by an arrow A in the figure. The face along the depth direction is sometimes referred to as the depth face. Further, in the present embodiment, the term "main view surface direction" is also used. The portion of the main viewing plane direction that extends in the horizontal direction as the frame 11 and the lower frame 12 or the upper frame 22 or the lower frame 23 as described above is a vertical direction orthogonal to the depth direction. A portion extending in the vertical direction, such as the vertical frame 13 or the vertical frame 24, is referred to as a main viewing surface direction along a horizontal direction orthogonal to the depth direction. The face along the direction of the main view is sometimes referred to as the main view.

As shown in Fig. 2, the door and window exemplified in the present embodiment is particularly considered to be unobstructed, and the lower frame 12 of the opening frame 10 is configured to have an upper surface in which the unevenness is rarely flat. On the other hand, the door leaf 20 applied to the door and window is configured to be commonly used for general doors and windows other than the barrier-free type, and the lower frame 23 is not provided with a tight member. That is, in a general door and window, since a door member which protrudes from the upper surface of the lower frame 12 is often provided with a tight member, the lower frame 23 of the door leaf 20 is not provided with a tight member. On the other hand, in the barrier-free door and window, as described above, the upper surface of the lower frame 12 needs to be formed to be almost flat, so that it is difficult to provide a door stopper or a tight member on the upper surface of the lower frame 12. Therefore, in the door and window of the present embodiment, the attachment 40 holding the tight member 30 is attached to the lower frame 23 of the door leaf 20, thereby achieving watertightness between the lower frame 23 and the lower frame 12.

Similarly to the lower frame 23, the attachment 40 is an extruded material formed of a metal such as an aluminum alloy or a resin, and has a substantially uniform cross section in the entire length along the longitudinal direction. As shown in FIGS. 6 to 9, in the present embodiment, an attachment 40 having an upper wall portion 41, a pair of side wall portions 42, and a pair of bottom wall portions 43 is applied. The upper wall portion 41 is a flat portion having a width that can be disposed between the frame drain holes 58 provided in the lower frame 23 . The pair of side wall portions 42 are flat portions that extend downward in the vertical direction from both side edge portions of the upper wall portion 41, and are configured to have substantially the same size as the lower fin portions 52 of the lower frame 23. The pair of bottom wall portions 43 are flat portions that extend substantially horizontally from the lower edges of the pair of side wall portions 42 toward each other. The bottom wall portion 43 on the outdoor side is configured to slightly protrude from the lower fin portion 52 when the upper wall portion 41 is disposed between the frame drain holes 58. The bottom wall portion 43 on the indoor side is configured to have a size in which the extending end surface substantially coincides with the outer surface of the lower fin portion 52 when the upper wall portion 41 is disposed between the frame drain holes 58.

Waterproof fins 44 and 45 are provided on the upper surface of each of the bottom wall portions 43 of the attachment member 40, and a tight member holding portion 46 is provided on each of the lower surfaces thereof. The waterproof fin portions 44 and 45 are flat portions extending upward from the upper surface of the bottom wall portion 43 in the vertical direction, and are configured such that when the upper wall portion 41 is disposed between the frame drain holes 58 The outer surface can abut against the inner surface of the lower fin 52. As is apparent from the figure, the waterproof fin portion 45 provided on the indoor side has a higher height than the waterproof fin portion 44 provided on the outdoor side. The tight member holding portion 46 is a groove-shaped portion that opens downward, and a continuous tight member 30 is held inside each of the tight member holding portions 46 at a portion penetrating the entire length of the attachment 40. The fastener 30 is held by the base holding portion 46 by the base portion, and the front end portions of the respective tight members 30 extend downward in a substantially parallel state.

As shown in FIG. 9, a plurality of drain holes 47 are provided in the attachment member 40. The drain hole 47 is formed by cutting the upper wall portion 41 and the pair of side wall portions 42 from the extrusion-molded attachment 40, and is provided corresponding to each of the frame drain holes 58 provided in the lower frame 23. More specifically, the drain hole 47 of the attachment member 40 is disposed to coincide with the position at which the frame drain hole 58 is provided in the longitudinal direction of the lower frame 23.

The attachment 40 having the above-described configuration is formed in such a manner that a rectangular parallelepiped portion composed of the upper wall portion 41 and the pair of side wall portions 42 protrudes upward from the two bottom wall portions 43. Therefore, when the waterproof fins 44 and 45 are respectively brought into contact with the lower fins 52, the mounting screws S are screwed to the lower wall 51b of the frame base 51 through the upper wall portion 41, that is, they can be attached to the lower frame 23 .

In this state, the fastener 30 is disposed to extend downward from the edge portion on the outdoor side and the edge portion on the indoor side in the lower portion of the lower frame 23, respectively. Furthermore, between the lower frame 23 and the attachment 40, two open chambers 48 are secured. That is, the lower frame 23 and the attachment 40 are in a state in which the lower fins 52 are in contact with the waterproof fins 44, 45 on the outdoor side and the indoor side, respectively, and in the central portion, the lower wall 51b of the frame base 51 is The upper wall portion 41 is in contact. On the other hand, between the waterproof fins 44, 45 and the side wall portion 42, the lower frame 23 and the attachment member 40 are separated from each other by the lower wall 51b of the frame base portion 51, the lower fin portion 52, and the bottom wall of the attachment member 40. The portion 43 and the side wall portion 42 secure an open chamber 48 that extends in the longitudinal direction of the lower frame 23, respectively. Each of the open chambers 48 communicates with the inside of the frame base portion 51 via the frame drain hole 58, and communicates with the outside via the drain hole 47.

The lower frame 12 of the opening frame 10 is formed of a metal such as an aluminum alloy or an extruded material formed of a resin so as to have substantially the same cross section over the entire length in the longitudinal direction. As shown in Fig. 6, in the present embodiment, the lower frame 12 having the deep wall portion 61, the inner side wall portion 62, the inclined bottom wall portion 63, and the outer side wall portion 64 is applied.

The deep wall portion 61 is a portion that extends in the depth direction. The edge portion 61a on the outdoor side of the deep wall portion 61 is gradually inclined upward toward the outside, and then extends substantially horizontally, and is further curved downward in the vertical direction. The front view wall portion 65 extends downward in the vertical direction at the edge portion of the deep wall portion 61 on the indoor side. The inner side wall portion 62 is a portion that extends downward from the lower surface of the edge portion 61a of the outdoor wall portion 61 on the outdoor side. The inclined bottom wall portion 63 is a portion that is gradually inclined downward from the lower edge of the inner side wall portion 62 toward the outside.

In the present embodiment, the outer side wall portion 64 is provided to extend upward from a portion located substantially in the middle of the inclined bottom wall portion 63, and then gradually slopes upward toward the outside, and further extends upward in the vertical direction.

In the outer side wall portion 64, a portion extending upward from the inclined bottom wall portion 63 is provided with an external discharge port 67 at a plurality of locations. The external discharge port 67 allows the lower end portion of the frame drain passage 66 to communicate with the outside. The extending edge portion 64a of the outer side wall portion 64 is gradually bent upward toward the indoor side, and is bent to be substantially horizontal. The portion of the extending edge portion 64a of the outer side wall portion 64 that is curved toward the indoor side is set to be slightly lower than the edge portion 61a of the deep wall portion 61 on the outdoor side. As can be seen from FIG. 6, the distance between the edge portion 61a on the outdoor side of the deep wall portion 61 and the extending edge portion 64a on the indoor side of the outer side wall portion 64 is set to be closer than that held by the attachment member 40. The front end portions of the members 30 are small in mutual spacing. In the case where the door leaf 20 is closed with respect to the opening frame 10, the front end portion of one of the tight members 30 held by the attachment member 40 abuts against the main viewing surface of the edge portion 61a of the outdoor wall portion 61 on the outdoor side, and The front end portion of the other tight member 30 abuts against the upper surface of the extended side edge portion 64a of the outer side wall portion 64 on the indoor side.

As shown in FIG. 6, in the lower frame 12, a cover member 70 is disposed between the edge portion 61a on the outdoor side of the deep wall portion 61 and the extended edge portion 64a on the indoor side of the outer side wall portion 64. The cover member 70 is an extruded material formed of a metal such as an aluminum alloy or a resin, and has a substantially uniform cross section in the entire length along the longitudinal direction. In the present embodiment, the cover member 70 having the cover base portion 71 having a width smaller than the gap between the outdoor side edge portion 61a and the outer side wall portion 64 on the indoor side extending edge portion 64a is applied. . The lid base portion 71 is gradually inclined downward from the central portion thereof toward the indoor side and the outdoor side, respectively. Mounting fins 72 are provided on the respective lower surfaces of both side edge portions of the cover base portion 71. The cover member 70 is attached between the edge portion 61a on the outdoor side of the deep wall portion 61 and the extending edge portion 64a on the inner side of the outer side wall portion 64 via the attachment fins 72 via the plurality of mounting brackets 73. The upper surface of the cover member 70 is set to have substantially the same height as the upper surface of the extended edge portion 64a of the outer side wall portion 64 on the indoor side. Between the both side edge portions of the cover base portion 71 and the edge portion 61a on the outdoor side of the deep wall portion 61 and the extended edge portion 64a on the indoor side of the outer side wall portion 64, the receiving ports of substantially the same size are secured to each other. 66a.

In the door and window constructed as described above, in the case where the door leaf 20 is closed with respect to the opening frame 10, as described above, the front end portion of the tight member 30 held by the attachment member 40 and the deep wall portion 61 are located in the chamber. The front surface of the outer edge portion 61a and the upper surface of the outer side wall portion 64 on the indoor side extending edge portion 64a abut. Therefore, there is no possibility that water such as rainwater from the outdoor side is infiltrated into the indoor side through the gap between the lower frame 23 of the door leaf 20 and the lower frame 12.

Here, in the case where water is caught between the end surface of the lower fin portion 52 provided in the lower frame 23 and the bottom wall portion 43 of the attachment member 40, between the lower fin portion 52 and the waterproof fin portion 44 which are in contact with each other Capillary phenomenon, water will be sucked up to the indoor side. However, according to this door and window, since the open chamber 48 is secured between the lower frame 23 and the attachment member 40, the capillary phenomenon is blocked in the open chamber 48, and the sucked water does not pass over the open chamber 48 to the indoor side. mobile. Also, the attachment member 40 is provided with a drain hole 47 that communicates with the open chamber 48. Therefore, the water accumulated in the open chamber 48 is discharged to the outside of the attachment member 40 via the drain hole 47 without being immersed in the chamber side. Further, the water discharged to the outside of the attachment 40 via the drain hole 47 passes through the inside of the lower frame 12 through the receiving port 66a of the frame drain passage 66, and is discharged to the outside through the external discharge port 67, so that there is no Dip into the side of the room.

Further, in this door and window, in the case where the door leaf 20 is closed with respect to the opening frame 10, the open chamber 48 secured between the lower frame 23 and the attachment member 40 is in communication with the outside via the drain hole 47 and the frame drain passage 66. status. Therefore, even in the case where the wind and rain outdoors is strong, since the open chamber 48 between the lower frame 23 and the attachment member 40 is always the same as the outdoor pressure, there is no possibility that water such as rainwater is immersed in the open due to the pressure difference. The situation inside the chamber 48 is the case.

Further, in the door and window, in the case where the water is immersed in the gap between the face material supporting fin portion 53 of the lower frame 23 and the glass plate 21 or the gap between the crimping edge 25 and the lower frame 23, the immersed water passes through the groove. The drain hole 56 or the pressurizing drain hole 57 is introduced into the inside of the frame base portion 51, and then is dropped to the bottom wall portion 43 of the attachment 40 via the frame drain hole 58. Therefore, the water which is immersed in the gap between the face material supporting fin portion 53 and the glass plate 21 of the lower frame 23 or the gap between the bead 25 and the lower frame 23 may be due to the lower fin portion 52 and the waterproof fin portion 44. Similarly, the water sucked up by the capillary phenomenon is discharged to the outside through the drain hole 47 without being immersed in the inside of the room. Further, in the door and window, the frame drain hole 58 corresponding to the drain hole 47 is provided, so that the water dropped from the frame base portion 51 hardly stays in the bottom wall portion 43 of the attachment member 40 and is quickly discharged from the drain hole 47. To the outside. When the water dropped from the frame base portion 51 is retained in the bottom wall portion 43 of the attachment 40, the waterproof fin portion 45 that largely protrudes from the bottom wall portion 43 is provided on the outdoor side. Therefore, the water accumulated in the bottom wall portion 43 does not reach the ridge between the waterproof fin portion 45 on the indoor side and the lower fin portion 52, and does not cause the oozing out to the indoor side due to the capillary phenomenon.

Further, in the above-described embodiment, the door and window separating the outdoor and the indoor are exemplified. However, the present invention is not limited thereto, and can be applied to, for example, a door and window for a bathroom that partitions between the bathroom and the changing room. In addition, the door sash does not have to be the door leaf 20. Further, although the case where the door sash is opened to the outdoor (second space) side with respect to the opening frame 10 is exemplified, the present invention is not limited thereto, and the door sash can be opened and closed with respect to the opening frame 10.

Further, in the above embodiment, since the two open chambers 48 are provided between the lower frame 23 and the attachment 40, it is possible to more reliably prevent the intrusion of water into the indoor (first space) side, but the open chamber 48 is at least The part located on the side of the indoor (first space) is provided with one foot. Further, since the open chamber 48 is communicated with the outdoor (second space) via the frame drain passage 66 provided in the lower frame 12, there is no risk of water intrusion due to a pressure difference from the outside as described above, but the present invention does not Must be limited to this.

Further, in the above-described embodiment, the drain hole 47 of the attachment 40 is provided in a position in which the frame drain hole 58 is provided in the longitudinal direction of the lower frame 23, so that the water discharged from the frame drain hole 58 can be made as described above. It is hardly retained in the bottom wall portion 43 of the attachment member 40 and is discharged to the outside. However, the drain hole 47 of the attachment member 40 does not have to coincide with the frame drain hole 58 in the longitudinal direction of the lower frame 23, for example, at least partially overlapped. In addition, the drain hole 47 is exemplified by cutting the upper wall portion 41 and the side wall portion 42. However, the present invention is not limited thereto. For example, the drain hole may be provided to penetrate the bottom wall portion 43.
