[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sliding door unit according to one embodiment of the present invention will now be described with reference to the drawings. In this embodiment, a sliding door unit 1 as shown in FIG. 1, which is incorporated into a knock-down curtain wall provided as an exterior wall of a building, will be described as an example.

[0010] As shown in Figures 1 to 4, the curtain wall forming the exterior wall of a building comprises vertical battens 31 or vertical frames 3 attached to multiple mullions 2 supported via fasteners on the building's framework, horizontal members 4 and 5 arranged above and below the vertical battens 31 and vertical frames 3 and spanning the multiple mullions 2, vertical battens 31 and vertical frames 3, and double-glazed glass 6 as a surface material arranged in a space S1 (the space on the left in Figure 1) formed by adjacent vertical battens 31 and vertical frames 3 and a pair of adjacent horizontal members 4 and 5 in the vertical direction. The mullions 2, vertical battens 31 and vertical frames 3 are extruded aluminum members arranged vertically, and the horizontal members 4 and 5 are extruded aluminum members arranged horizontally.

[0011] In the following explanation, when the sliding door unit 1 incorporated into the curtain wall is viewed from the outside, the up and down direction is referred to as the up and down direction, the left and right direction is referred to as the left and right direction, and the depth direction, which is the indoor / outdoor direction, is referred to as the projection direction. Even when each part of the sliding door unit 1, or each component that constitutes the sliding door unit 1 is in a standalone state, the directions will be specified and explained in terms of the up and down direction, left and right direction, and projection direction when the sliding door unit 1 is incorporated into the curtain wall.

[0012] As shown in Figure 2, the sliding door unit 1 of this embodiment is installed in two spaces S1 and S2 that are aligned in the left-right direction. Of the two adjacent spaces S1 and S2, the left space S1 has double-pane glass 6 arranged therein, just like the other spaces S where the sliding door unit 1 is not installed, to form a fixed window 1a, and the right space S2 has an opening 1b formed by a vertical frame 3 and upper and lower horizontal members 4 and 5.

[0013] The sliding door unit 1 has one vertical batten 31 attached to three mullions 2 spaced apart in the left-right direction, two vertical ribs 3, and an upper horizontal member 4 and a lower horizontal member 5 connecting the upper and lower ends of the one vertical batten 31 and the two vertical ribs 3, respectively. The vertical batten 31 is attached to the leftmost mullion 2 of the three mullions 2. The vertical rib 32 attached to the central mullion 2 of the three mullions 2 (hereinafter also referred to as the middle vertical rib) forms a fixed window 1a, and the middle vertical rib 32 and the rightmost vertical rib 33 of the three mullions 2 form an opening 1b that can be closed by a shoji screen 7. The upper and lower horizontal members 4 and 5 are attached between the vertical batten 31 and the right vertical rib 33 and are fixed to the two vertical ribs 32 and 33, respectively. Therefore, the upper and lower horizontal members 4, 5 and the two vertical frames 32, 33 of the sliding door unit 1 can be attached to the mullions 2 in a pre-joined state.

[0014] As shown in Figure 5, the mullion 2 has a substantially rectangular main body 2a and two protrusions 2b and 2c that protrude from the main body 2a toward the outdoors. The two protrusions 2b and 2c are spaced apart in the left-right direction.

[0015] The left protruding portion 2b located on the left side has a left extending portion 2d extending outdoors from the left visible surface of the main body portion 2a, a left opposing portion 2e located on the right side of the left extending portion 2d and facing it at a distance, and a left outdoor surface portion 2f connecting the outdoor ends of the left extending portion 2d and the left opposing portion 2e to form the visible surface.

[0016] The right protrusion 2c located on the right side has a right extension portion 2g extending outdoors from the right visible surface of the main body portion 2a, a right opposing portion 2h located on the left side of the right extension portion 2g and facing it at a distance, and a right outdoor surface portion 2i connecting the outdoor ends of the right extension portion 2g and the right opposing portion 2h to form the visible surface.

[0017] The left opposing portion 2e of the left protruding portion 2b and the right opposing portion 2h of the right protruding portion 2c are opposed to each other with a gap in the left-right direction, and each protrudes to the opposite side and has an engaging portion 2j with which the vertical push edge 31 or vertical bone 3 is engaged.

[0018] Backup material locking portions 2k that protrude outdoors and lock the backup material 8 are provided at the left ends of the left outdoor surface portion 2f and the right outdoor surface portion 2i. Of the two mullions 2 on which the pair of vertical frames 32, 33 that form the opening 1b are provided, the backup material locking portion 2k provided on the right outdoor surface portion 2i of the mullion 2 located on the left side (hereinafter also referred to as the left mullion) 2 locks the middle vertical frame 32, and the backup material locking portion 2k provided on the right outdoor surface portion 2i of the mullion 2 located on the right side (hereinafter also referred to as the right mullion) 2 locks the right vertical frame 33.

[0019] As shown in Figure 2, the vertical ledge 31 also forms the right-hand vertical ledge 31 that constitutes the fixed window 9 in the space S3 to the left of the two spaces S1 and S2 in which the sliding door unit 1 is installed, and the same vertical ledge 31 is also used on the left-hand side that constitutes the fixed window 9 to the left. Note that, except for the spaces S1 and S2 in which the sliding door unit 1 is incorporated, the left and right vertical ledges 31 that form the space S in which the fixed window 9 is installed are the same components as the vertical ledge 31 in the sliding door unit 1.

[0020] The vertical batten 31 has a plate-shaped vertical batten plate portion 31a that forms the visible surface, a vertical batten side engaging portion 31b that is provided on the indoor side of the vertical batten plate portion 31a and engages with the engaging portion 2j of the mullion 2, and a vertical batten outdoor portion 31c that is provided on the outdoor end of the vertical batten plate portion 31a.

The left-right width of the right vertical frame 33 is approximately the same as the left-right width W1 of the vertical ledge outdoor portion 31c and is also approximately the same as the left-right width W2 of the mullion 2.

[0029] The right vertical frame 33 is engaged with the right mullion 2 with the right vertical frame indoor extension portion 33b engaged with the engagement portion 2j of the left protrusion 2b and the backup material engaging portion 2k.

[0030] The outdoor extension surface portion 33d has a water-stopping material 11 provided on the left end side, the right vertical frame projection surface portion 33c, so that it is exposed to the outdoors, and the right end has a right extension portion 33e that extends indoors, and a right vertical frame facing portion 33f that extends leftward from the indoor side end of the right extension portion 33e and faces the right outdoor surface portion 2i of the right protrusion portion 2c of the right mullion 2 with a gap in the projection direction.

[0031] The left peripheral edge of the double-glazed glass 6 arranged in the space S4 on the right side of the sliding door unit 1 is accommodated between the right vertical frame facing portion 33f of the right vertical frame 33 and the right outdoor facing portion 2i of the right mullion 2, and the double-glazed glass 6 is held between the right vertical frame facing portion 33f and the right outdoor facing portion 2i and the double-glazed glass 6 via a backup material 8 and a sealant 10, respectively. When the right vertical frame 33 is engaged with the right mullion 2 and holds the double-glazed glass 6, the right vertical frame front surface portion 33c forms a surface that is flush with the front surface on the left side of the right mullion 2, and the right extension portion 33e is located on the same plane as the front surface on the right side of the right mullion 2. In addition, the outdoor-facing surface of the outdoor extension surface portion 33d is located on the same plane as the outdoor-facing surface of the vertical ledge outdoor portion 31c of the vertical ledge 31.

[0032] As shown in Figure 8(a), the upper cross member (hereinafter also referred to as the upper cross member) 4 has an upper vertical joint 4a having an indoor facing surface and joined to the mullion 2 via a bracket 12, an upper cross member extension 4b extending to the outdoor side from approximately the center of the upper vertical joint 4a, an upper cross member erection portion 4c erected upward from the outdoor end of the upper cross member extension portion 4b, an upper cross member indoor extension portion 4d extending to the indoor side from the upper end of the upper cross member erection portion 4c, an upper cross member opposing portion 4e hanging downward from the indoor edge of the upper cross member indoor extension portion 4d and facing the upper vertical joint 4a with a gap in the forward direction, an upper cross member upper surface portion 4f extending approximately horizontally to the outdoor side from the upper end of the upper cross member erection portion 4c, and an upper cross member hanging plate portion 4g hanging from the outdoor end of the upper cross member upper surface portion 4f.

[0033] The lower peripheral edge of the double-glazed glass 6 arranged in the space S5 above the sliding door unit 1 is accommodated between the upper cross member facing portion 4e and the upper vertical joint 4a of the upper cross member 4, and the double-glazed glass 6 is held between the upper cross member facing portion 4e and the upper vertical joint 4a and the double-glazed glass 6 via a backup material 8 and a sealant 10, respectively. An upper ledge fitting portion 4i into which the upper ledge 4h fits is provided at the outdoor end of the upper cross member extension portion 4b.

[0034] An upper ledge 4h is fitted into the upper ledge fitting portion 4i provided between the central vertical frame 32 and the vertical ledge 31. The upper end of the double-glazed glass 6 arranged between the central vertical frame 32 and the vertical ledge 31 is accommodated between the upper ledge 4h and the upper vertical joint 4a, and the double-glazed glass 6 is held between the upper ledge 4h and the upper vertical joint 4a and the double-glazed glass 6 via a backup material 8 and a sealant 10, respectively. Here, the space between the upper ledge 4h and the upper vertical joint 4a corresponds to the panel accommodation portion 4j in which the upper end of the double-glazed glass (panel) 6 is accommodated.

[0035] As shown in Figure 8(b), an upper closing member 13 is fitted between the middle vertical rib 32 and the right vertical rib 33 of the upper cross member 4 and below the upper cross member extension 4b, connecting with the underside of the upper vertical joint 4a to form a flat surface. The outdoor end of the upper closing member 13 is fitted into the upper ledge fitting portion 4i, and a water-stopping material 11 is provided below the upper ledge fitting portion 4i so as to be exposed to the outdoor side.

[0036] The upper indoor extension portion 4d and the upper cross member upper surface portion 4f form a connected horizontal plane and are located at the same height as the upper surface of the upper vertical joint portion 4a. Furthermore, when the double-glazed glass 6 is held in place, the outdoor surface of the upper horizontal member standing portion 4c and the outdoor surface of the upper batten 4h are located on the same plane as the outdoor surfaces of the outdoor extension surfaces 32d, 33d of the middle vertical frame 32 and the right vertical frame 33, and the outdoor surface of the vertical batten outdoor portion 31c of the vertical batten 31.

[0037] The area of ​​the upper cross member 4 facing outdoors beyond the upper cross member erection part 4c, the upper cross member upper surface part 4f and the upper cross member hanging plate part 4g has a shoji receiving part 4k which is a groove-like opening downward, and is provided over the entire longitudinal length of the upper cross member 4. The shoji receiving part 4k receives the upper end of the shoji 7 and serves as a guide part to guide the shoji 7 as it slides left and right.

[0038] As shown in Figure 9(a), the lower cross member (hereinafter also referred to as the lower cross member) 5 has a lower vertical joint 5a which has a visible surface facing indoors and is joined to the mullion 2 via a bracket 12, a lower cross member extension 5b which extends outdoors below the lower vertical joint 5a, and a lower cross member outdoor extension 5c which extends further outdoors from the outdoor end of the lower cross member extension 5b.

[0039] The outdoor end of the lower cross member extension 5b is provided with a lower ledge fitting portion 5e into which the lower ledge 5d is fitted. The lower ledge 5d is fitted into the lower ledge fitting portion 5e provided between the central vertical frame 32 and the vertical ledge 31, and the fitted lower ledge 5d faces the lower vertical joint 5a. The lower end of the double-glazed glass 6 arranged between the central vertical frame 32 and the vertical ledge 31 is accommodated between the lower ledge 5d and the lower vertical joint 5a, and the double-glazed glass 6 is held between the lower ledge 5d and the lower vertical joint 5a and the double-glazed glass 6 via a backup material 8 and a sealant 10, respectively. Here, the space between the lower ledge 5d and the lower vertical joint 5a corresponds to the panel accommodation portion 5f into which the lower end of the double-glazed glass (panel) 6 is accommodated.

[0040] As shown in Figure 9(b), a lower blocking member 14 is fitted on top of the lower horizontal member extension 5b between the middle vertical rib 32 and the right vertical rib 33 of the lower horizontal member 5, connecting with the upper surface of the lower vertical joint 5a to form a flat surface. The outdoor end of the lower blocking member 14 is fitted into the lower edge fitting portion 5e, and a water-stopping material 11 is provided on top of the lower edge fitting portion 5e so as to be exposed to the outdoor side.

[0041] When the double-pane glass 6 is held in place, the outdoor surface of the fitted lower edge 5d is located on the same plane as the outdoor surfaces of the outdoor extension surfaces 32d, 33d of the middle vertical frame 32 and the right vertical frame 33, and the outdoor visible surface of the vertical edge outdoor portion 31c of the vertical edge 31.

[0042] In the lower cross member 5, at approximately the center of the projecting direction of the lower cross member outdoor extension portion 5c, which is located on the outdoor side of the fitted lower edge 5d, a rail 5g is provided that protrudes upward and runs along the left-right direction, serving as a guide portion to guide the shoji screen 7, which slides left and right.

[0043] The shoji screen 7 has a frame body 70 made up of upper and lower horizontal frames 7a and left and right vertical frames 7b joined in a rectangular shape, and is installed so that the peripheral edge of the double-glazed glass 6 is housed inside the frame body 70. The lower horizontal frame 7a of the shoji screen 7 is equipped with a roller 71, and the upper horizontal frame 7a is housed in the shoji housing portion 4k of the upper cross member 4, and the roller 71 rolls on the rail 5g attached to the lower cross member 5, allowing the shoji screen 7 to slide left and right.

[0044] The shoji receiving portion 4k and the rail 5g of the lower horizontal member outdoor extension portion 5c are provided on the outdoor side of the upper and lower ledges 4h and 5d that hold the double-glazed glass 6, so the shoji 7 can slide left and right on the outdoor side of the double-glazed glass 6. Furthermore, the upper horizontal member 4 with the shoji receiving portion 4k and the lower horizontal member 5 with the rail 5g are provided between the vertical ledge 31 and the right vertical frame 33, so the shoji 7 is configured to be movable from a closed position where the left and right vertical frames 7b face the middle vertical frame 32 and the right vertical frame 33 to close the opening 1b, to an open position where they face the fixed window 1a of the sliding door unit 1 and most of the opening is open. When the shoji screen 7 is in the closed position, the frame 70 abuts against the water-stopping material 11 provided on the middle vertical frame 32, right vertical frame 33, upper horizontal member 4 and lower horizontal member 5, thereby preventing water from entering between the frame 70 and the middle vertical frame 32, right vertical frame 33, upper horizontal member 4 and lower horizontal member 5.

[0045] The left and right vertical frames 7b of the shoji screen 7 have a width W3 in the left-right direction that is approximately equal to the width W2 of the upright 2 and the width W1 of the vertical edge 31 and vertical frame 3 in the left-right direction, and when the shoji screen 7 is in the closed position, the vertical frames 7b are positioned so as to overlap the upright 2, vertical edge 31 and vertical frame 3 in the forward direction, and therefore do not protrude to the left or right of the upright 2, vertical edge 31 and vertical frame 3.

[0046] According to the sliding door unit 1 of this embodiment, the horizontal members 4, 5 located above and below the middle vertical frame 32 and the right vertical frame 33 are extended further to the left than the distance between the middle vertical frame 32 and the right vertical frame 33, and a shoji screen accommodating section 4k and a rail 5g that guide the shoji screen 7 are provided on the outdoor side of the panel accommodating sections 4j, 5f that accommodate the upper and lower ends of the double-glazed glass 6, so that the shoji screen 7 can be moved left and right on the outdoor side of the fixed window 1a to open and close the opening 1b.

[0047] Furthermore, the shoji screen 7 closes the opening 1b formed by the middle vertical frame 32, right vertical frame 33, upper horizontal member 4, and lower horizontal member 5, with the vertical frame 7b positioned opposite the middle vertical frame 32 and right vertical frame 33 in the front direction, so that when the opening 1b is closed, the vertical frame 7b is positioned opposite the middle vertical frame 32 and right vertical frame 33 in the front direction, and the vertical frame 7b is unlikely to be exposed to the interior side. Therefore, it is possible to provide a sliding door unit 1 that has excellent design while being equipped with a shoji screen 7 that serves as a sliding door.

[0048] Furthermore, when the shoji screen 7 closes the opening 1b, the vertical frame 7b, whose width W3 in the left-right direction is approximately the same as the width W2 of the mullion 2 and the width W1 of the middle vertical frame 32 and right vertical frame 33, does not protrude to the left or right of the mullion 2, middle vertical frame 32, or right vertical frame 33. This allows for a narrower joint where the vertical frame 7b overlaps with the vertical frame 2, the middle vertical frame 32, or the right vertical frame 33. This results in an excellent design whether viewed from indoors or outdoors. Furthermore, if the width W3 of the vertical frame 7b is less than the width W2 of the mullion 2 and the width W1 of the vertical edge 31 and vertical frame 3, the vertical frame 7b is less likely to be exposed indoors, thereby further enhancing the design.

[0049] Furthermore, when the shoji screen 7 opens the opening 1b, the shoji screen 7 can be moved to a position where the vertical frame 7b faces the vertical edge 31 and the central vertical rib 32 in the projection direction, so that even when the shoji screen 7 opens the opening 1b, it is possible to narrow the width of the so-called joint where the mullion 2, the vertical edge 31 or the central vertical rib 32 and the vertical frame 7b overlap in the projection direction. Therefore, even when the shoji screen 7 opens the opening 1b, it has an excellent design whether viewed from inside or outside.

[0050] Furthermore, since the middle vertical frame 32, right vertical frame 33 and upper horizontal member 4 and lower horizontal member 5 can be joined while they are separated from the mullions 2, it is possible to join the middle vertical frame 32, right vertical frame 33 and upper horizontal member 4 and lower horizontal member 5 in equipment such as a factory, and then attach them to the mullions 2 in this joined state at the construction site. This allows the middle vertical frame 32, right vertical frame 33 and upper horizontal member 4 and lower horizontal member 5 to be joined more accurately, and improves workability at the construction site.

[0051] In the above embodiment, the sliding door unit 1 has been described as an example in which a fixed window 1a and a shoji screen 7 form a single sliding door with a closable opening 1b, and the shoji screen 7 can move to one side in the left-right direction from a state in which the opening 1b is closed until it overlaps with the fixed window 1a. However, this is not limited to this. For example, the sliding door unit may be a free-standing single sliding door in which the upper and lower cross members extend on both sides of the opening in the left-right direction, and the shoji screen can move to either side in the left-right direction from a state in which the opening is closed, until it overlaps with the fixed window 1a on either side. In this case, it is possible to provide a sliding door unit that is even easier to use.

[0052] Furthermore, the above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.

[0053] The present embodiment includes at least the following inventions. The structure comprises a pair of vertical ribs provided on a pair of adjacent uprights among a plurality of uprights spaced apart from each other in the left-right direction, the pair of uprights protruding to the exterior side from the pair of uprights; a vertical push edge provided on the exterior side of one of the pair of uprights and the other adjacent upright on the opposite side of the other of the pair of uprights; horizontal members extending in the left-right direction beyond the gap between the pair of vertical ribs and positioned above and below the pair of vertical ribs; and a shoji screen supported by the horizontal members and movable in the left-right direction. The horizontal member has a panel storage section in which the upper and lower ends of the panel member are stored, and a guide section located on the outdoor side of the panel storage section that guides the shoji screen; the panel member is arranged with its ends stored in one of the vertical bones, the vertical push edge, and the upper and lower horizontal members; the shoji screen closes the opening formed by the pair of vertical bones and the horizontal member when the vertical frame is positioned opposite the pair of vertical bones in the front direction, and opens the opening by moving the panel member to the outdoor side.This is a sliding door unit characterized by the above.

[0054] With this type of sliding door unit, the horizontal members located above and below a pair of vertical beams are arranged to extend further left and right than the distance between the pair of vertical beams, and a guide section is provided to guide the shoji screen to the outside side of the panel material storage section in which the upper and lower ends of the panel material are stored, so that the shoji screen can be moved left and right outside the panel material to open and close the opening.

[0055] In addition, the shoji screen closes the opening formed by the pair of vertical ribs and horizontal members with the vertical stiles facing the pair of vertical ribs in the projection direction, so when the opening is closed, the vertical stiles are positioned facing the pair of vertical ribs in the projection direction, and are not easily exposed to the interior. This makes it possible to provide a sliding door unit with excellent design while still having a sliding door.

[0056] Such a sliding door unit is characterized in that the width of the vertical frame in the left-right direction is equal to or less than the width of the upright in the left-right direction, and does not protrude to the left or right of the upright when the opening is closed.

[0057] With this type of sliding door unit, the vertical frame does not protrude to the left or right of the upright when the shoji screen is closed, so it is possible to narrow the width of the so-called joint (visible width) where the upright and vertical frame overlap in the front direction.This makes it an attractive design when viewed from both indoors and outdoors.

[0058] The sliding door unit is characterized in that the pair of vertical frames and the horizontal member can be joined in a state separated from the mullions. With this type of sliding door unit, the pair of vertical frames and horizontal members can be joined together while separated from the upright, so the vertical frames and horizontal members can be joined together in a facility such as a factory, and then attached to the upright in that joined state at the construction site. This allows for more accurate joining of the vertical frames and horizontal members, and improves workability on site.

[0059] In such a sliding door unit, the horizontal member extends beyond the opening on both sides in the left-right direction. With this type of sliding door unit, the horizontal members extend to both sides of the opening in the left-right direction, so the shoji screen can be moved to either side in the left-right direction when the opening is closed, making it possible to provide a sliding door unit that is easy to use.
