Further, the downwardly extending portion 45 of the windshield 40 is formed in a shape along the inclined surface portion 126 and the outer surface portion 127 of the lower frame main body 124. As described above, the windshield plate 40 is in close contact with each part of the lower frame 12, so that the lower frame internal space 125 below the summing unit 23 is separated from the left and right indoor side spaces 125A as shown in FIG. The outer space 125B can be partitioned.

On the other hand, a sliding member 50 serving as a heel-side airtight member is attached to the lower end of the vertical saddle (summing rod) 18B of the outdoor shoji 15B constituting the summing unit 23.
As shown in FIGS. 11 and 15, the sliding member 50 includes a main body 51, two insertion portions 52 and 53 inserted into the vertical rod 18 </ b> B, and a prospective side surface of the vertical rod 18 </ b> B (right side in FIG. 11). A front surface portion 54 exposed on the side surface), a door stop portion 55 projecting from the front surface portion 54, and a sliding piece portion being a hanging piece projecting downward from the main body portion 51. 56 and two projecting pieces 57 and 58 provided on the indoor side surface and bottom surface of the main body 51. Further, a groove-shaped mohair mounting portion 59 is formed on the bottom surface of the main body 51 of the sliding member 50, and a mohair 59A is attached to the mohair mounting portion 59 as shown in FIGS. ing. When the outdoor shoji 15B is opened / closed, the mohair 59A is in sliding contact with the upper surfaces of the outdoor rail portion 30B, the outdoor lateral airtight member 31B, and the inter-rail upper surface members 32C and 32D.
That is, in the state where the shoji 15A and 15B are closed, the upper surfaces of the outdoor rail 30B, the outdoor lateral airtight member 31B, and the upper rail members 32C and 32D are exposed (positioned) in the outdoor space. The mohair 59A is slidably contacted with these upper surfaces to remove dust and sand, or the outdoor rail portion 30B and the door wheel 174 are damaged by the dust and sand. Can be prevented from being attached.
When the outdoor shoji 15B is closed, the mohair 59A is located between the outdoor shoji 15B and the lower frame 12 at a position on the right side in FIG. 10 with respect to a first drain hole 44A of the windshield 40 described later. As a result of the blockage, dust, sand or the like is less likely to enter the first drain hole 44A.

The sliding member 50 is fixed to the vertical rod 18B by screwing from the front surface portion 54 with the insertion portions 52 and 53 inserted from the lower end of the vertical rod 18B. And the protrusion piece part 57 provided in the indoor side surface of the main-body part 51 fits into the notch | incision formed along the smoke return 184 of the indoor side surface of the vertical rod 18B, as shown in FIG. It protrudes to the indoor side from the side surface of the vertical rod 18B, and continues to the lower end portion of the vertical airtight material 185 provided on the indoor side surface of the vertical rod 18B. Note that the vertical airtight member 185 is a member that keeps the airtightness in contact with the outdoor side surface of the vertical rod 18A in the indoor shoji 15A. The door contact portion 55 provided on the front surface portion 54 prevents the vertical contact 18B from directly hitting the vertical frame 13 by the door contact portion 55 coming into contact with the vertical frame 13 when the outdoor shoji 15B is opened. It is for preventing.
Further, as shown in FIGS. 9 and 10, the sliding piece portion 56 of the sliding member 50 is inserted into a gap between the outdoor side airtight material 31 </ b> B and the screen door rail 34, continuing from the hanging piece 175 of the lower rod 17. The outdoor side airtight member 31B is in contact with the indoor side surface of the sliding piece 56. A chamfered portion 56A is formed at the end of the sliding piece portion 56. When the sliding door 15B is transported or attached to or detached from the window frame 14 with the sliding member 50 attached to the vertical rod 18B, the sliding piece 56A is slid. The end portion of the moving piece portion 56 is less likely to collide and become difficult to break. Note that the form of the chamfered portion 56A is arbitrary, and the chamfered portion 56A may be linearly formed with an appropriate inclination.

The windshield plate 40 and the sliding member 50 as described above constitute an airtight and watertight structure below the summing portion 23 of the sliding window 10 of the present embodiment.
That is, as shown in FIGS. 9 and 10, when the shoji 15 is closed, the projecting piece 43 of the windshield 40 and the projecting piece 58 of the sliding member 50 come into contact with each other, and the projecting piece of the sliding member 50 is brought into contact. The portion 57 abuts against the vertical side 18A (not shown) of the indoor shoji 15A, and the hanging piece 175 (not shown) at the lower end of the indoor shoji 15A is connected to the projecting piece 43 of the windshield 40 and the By contacting the first sub-projecting piece 43A, the gap between the indoor and outdoor shojis 15A and 15B and the lower frame 12 is closed, and the indoor and outdoor spaces are blocked. Thus, a horizontal airtight line in the lower frame 12 and the indoor and outdoor shojis 15A and 15B and a vertical airtight line in the summing unit 23 are formed.
Of the drainage holes 44 provided on the left and right sides in the lower frame longitudinal direction (right and left sides in FIG. 10) of the projecting piece 43 of the windshield plate 40, one drainage hole 44 (on the right side in FIG. 10) has a lower frame. The first drain hole 44 </ b> A communicated with the outdoor space 125 </ b> B of the internal space 125, and the other drain hole 44 (the left side in FIG. 10) is the second drain water communicated with the indoor space 125 </ b> A of the lower frame internal space 125. It is a hole 44B.

  When rainwater with wind blows from the outside in the direction in which the vertical rod 18B is found in the outdoor shoji 15B (right side in FIG. 10), the vertical rod 18B and the rail upper surface member 32C exposed to the outside The rainwater tries to enter the lower part of the summing portion 23 along the upper surface of the upper surface member 32C between the rails and between the rails. The rainwater enters the chamber of the lower frame internal space 125 from the first drain hole 44A of the windshield plate 40. It falls into the outer space 125B, flows through the inclined surface portion 126 of the lower frame main body 124, and is drained into the outdoor space through the drain hole 127A. Even if a part of the rainwater exceeds the first drain hole 44A of the windshield 40, the rainwater is in contact with the projecting piece 43 of the windshield 40 and the projecting piece 58 of the sliding member 50. Therefore, it cannot enter the indoor side and is drained from the first drain hole 44A in the same manner as described above. Furthermore, even if rainwater exceeds the protruding piece 43 of the windshield plate 40 and the protruding piece 58 of the sliding member 50, the rainwater flows into the lower frame from the second drain hole 44 </ b> B of the windshield 40. It falls into the indoor space 125A of the space 125 and is drained into the outdoor space via the drain hole 127A and the drain valve 39, and does not enter the indoor space along the upper surface of the rail upper surface member 32B.

  In the above, the upper end of the projecting piece portion 43 of the windshield 40 contacts the projecting piece portion 58 of the sliding member 50, but does not contact the other portions of the outdoor shoji 15B. The lower end of the protruding piece portion 58 of the sliding member 50 is in contact with the protruding piece portion 43 of the windshield plate 40 but is not in contact with other portions of the lower frame 12. That is, only when the outdoor shoji 15B is completely closed, the projecting piece 43 of the windshield 40 and the projecting piece 58 of the sliding member 50 come into contact with each other. Thereby, when opening and closing the outdoor shoji 15B, the protruding piece 43 of the windshield 40 does not slide in contact with the outdoor shoji 15B, and the protruding piece 58 of the sliding member 50 is the lower frame 12. Therefore, the opening / closing resistance is reduced, and the sliding door 15B on the outdoor side can be smoothly opened / closed even with a small force.

According to this embodiment, there are the following effects.
(1) That is, the indoor and outdoor rail portions 30A and 30B attached to the lower frame 12, the indoor and outdoor horizontal airtight materials 31A and 31B, the inter-rail upper surface member 32, the indoor upper surface member 33, and the upper end of the screen door rail 34 Are provided at substantially the same height, so that the upper surface of the lower frame 12 can be formed flat, and there is a sense of incongruity when the upper surface of the lower frame 12 is stepped on with a foot or rattling when passing by a wheelchair. Thus, the sliding window 10 that can be barrier-free can be configured.

(2) Further, the rail upper surface member 32 is divided on both sides of the windshield plate 40, and the handle portion 322 on the lower frame longitudinal direction center side end side is brought into contact with the windshield plate 40, thereby the rail upper surface member. There is no possibility of rainwater entering the room through the member 32. Further, the wind stop plate 40 that partitions the lower frame internal space 125 can surely prevent the intrusion of rainwater, and can sufficiently secure the water stop performance.

(3) Furthermore, by providing the windshield plate 40 with the first and second drain holes 44A and 44B, rainwater entering the indoor side from below the summing portion 23 of the shoji 15 is projected from the windshield plate 40. The rainwater can be dropped and drained from the first drainage hole 44A to the outdoor space 125B of the lower frame internal space 125 by being blocked by the piece 43 and the protruding piece 58 of the sliding member 50.

(4) Even if rainwater exceeds the protruding piece 43 of the windshield plate 40 and the protruding piece 58 of the sliding member 50, the rainwater is lowered from the second drain hole 44B of the windshield 40. It can be dropped and drained into the indoor space 125A of the frame internal space 125, and rainwater can be prevented from entering the indoor space to further improve the water stopping performance.

(5) Moreover, since the rail part 30 is not divided | segmented regarding the longitudinal direction of the lower frame 12, and is comprised from one continuous member without a joint on the way, when opening / closing the shoji 15, the doorwheel 174 is a seam. It is possible to smoothly guide the door 174 of the shoji 15 without being rattled or making a sound.

(6) Further, by removing the inter-rail upper surface member 32, the indoor side upper surface member 33, and the screen door rail 34, it is possible to clean the groove portions 121D and 122D between the rail portions 30 and indoors without removing the rail portion 30. The cleaning operation can be performed with peace of mind without the possibility of the shoji 15 falling off during cleaning.

(7) Further, the upper end of the projecting piece portion 43 of the windshield 40 is located below the bottom surface of the shoji 15, and the lower end of the projecting piece portion 58 of the sliding member 50 is located above the upper surface of the lower frame 12. When the outdoor shoji 15B is opened and closed, the protruding piece 43 of the windshield 40 does not slide on the outdoor shoji 15B, and the protruding piece 58 of the sliding member 50 does not slide on the lower frame 12. Therefore, the opening / closing resistance is reduced, and even with a small force, the outdoor shoji 15B can be opened / closed smoothly, and the operability can be improved.

(8) Further, gaps are formed on the outdoor sides of the indoor and outdoor lateral airtight materials 31A and 31B, and the lateral airtight materials 31A and 31B come into contact with the hanging pieces 175 of the shoji 15 inserted in these clearances. An airtight line between the lower frame 12 and the shoji 15 is formed. The width dimension of the gap provided along the horizontal airtight materials 31A and 31B only needs to have a minimum dimension that allows the drooping piece 175 to be inserted, and the airtight line can be formed only by providing the minimum gap. Since it can be formed, it is not necessary to provide a large gap or unevenness, so that the upper surface of the lower frame 12 can be formed further flat.

(9) Further, by inserting the hanging piece 175 of the shoji 15 into the gap along the lateral airtight members 31A and 31B, the gap between the lower edge of the shoji 15 and the upper surface of the lower frame 12 cannot be seen on the appearance of the window, and the appearance The design is improved, and the act of removing the shoji 15 by inserting a tool such as a bar from the outdoor side between the lower end of the shoji 15 and the lower frame 12 can be prevented, and the crime prevention performance can be improved.

(10) Further, since the inter-rail upper surface member 32 is divided into four at the midway position in the longitudinal direction of the lower frame 12, it is not necessary to remove the shoji 15 only by bringing the shoji 15 to one side of the window frame 14. The inter-rail upper surface member 32 can be easily detached.

(11) Further, since the horizontal airtight materials 31A and 31B are detachably provided from the upper surface side of the lower frame 12, even when the horizontal airtight materials 31A and 31B are worn, it is easy from above the lower frame 12. It is possible to replace the side airtight materials 31A and 31B.

(12) Furthermore, since the rail portion 30 is detachable from the lower frame main body 124, the rail portion 30 can be replaced even if the rail portion 30 is damaged. Moreover, even if the door guides 301 and 302 of the rail portion 30 are changed to a convex shape or a concave shape according to the form of the door wheel 174 of the shoji 15, there is no need to change the shape of the lower frame main body 124. This can be dealt with by replacing only the unit 30.

(13) Further, in the lower frame main body 124 in which the indoor member 121 and the outdoor member 122 are connected by the heat insulating member 123, the indoor rail portion 30A located in the indoor space when the shoji 15 is closed, the indoor upper surface A sliding window which is a heat insulating sash by providing the member 33 and the side airtight material 31A on the indoor member 121 and making the rail upper surface members 32A and 32B located in the indoor space when the shoji 15 is closed from resin.
