Mode for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The fitting of this embodiment shows the sliding window 1.

[0009] In this specification, the "looking direction" means the surface direction of the facing materials 35 and 45 in the sliding window 1 housed in the opening formed in the wall of the building, and the "looking direction" means the thickness direction (that is, the depth direction) of the facing materials 35 and 45. The "looking direction" is also the indoor-outdoor direction. The "looking surface" means the respective surfaces facing the outdoor side and the indoor side in the sliding window 1, and the "looking surface" means the surface extending in the indoor-outdoor direction in the sliding window 1. In the drawings, the outdoor side of the sliding window 1 is defined as the outdoor side X1, and the indoor side of the sliding window 1 is defined as the indoor side X2.

[0010] As shown in FIGS. 1 and 2, the sliding window 1 includes a frame body 2 attached to an opening of a building body (not shown), and an outer shutter 3 and an inner shutter 4 disposed inside the frame body 2.

[0011] The frame body 2 is configured by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23 and 24 into a rectangle.

[0012] Both the outer shutter 3 and the inner shutter 4 are sliding doors, and by being configured to be slidable in the left - right direction (horizontal direction) of the viewing direction, an opening of the frame body 2 is closed or opened, constituting a so - called sliding window.

[0013] The outer shutter 3 is configured by storing a face material 35 composed of two pieces of glass inside a frame body 30 formed by framing an upper frame 31, a lower frame 32, a vertical frame 33 arranged on the leading - edge side of the door, and an outer - meeting - frame 34 which is a vertical frame arranged on the trailing - edge side of the door into a rectangle. The outer shutter 3 is arranged to be movable in the left - right direction on the outdoor side X1 within the frame body 2. The frames of the outer shutter 3 (the upper frame 31, the lower frame 32, the vertical frame 33 arranged on the leading - edge side of the door, and the outer - meeting - frame 34 which is a vertical frame arranged on the trailing - edge side of the door) can be formed, for example, by extrusion - molding aluminum. The frames of the outer shutter 3 have a higher thermal conductivity compared to the face material 35 made of glass. Therefore, by reducing the width of the frames in the viewing direction and minimizing the exposure of the frames to the indoor side X2, the heat - insulation performance and dew - prevention performance of the sliding window 1 are enhanced.

[0014] The inner shutter 4 is configured by storing a face material 45 composed of two pieces of glass inside a frame body 40 formed by framing an upper frame 41, a lower frame 42, a vertical frame 43 arranged on the leading - edge side of the door, and an inner - meeting - frame 44 which is a vertical frame arranged on the trailing - edge side of the door into a rectangle. The inner shutter 4 is arranged to be movable in the left - right direction on the indoor side X2 within the frame body 2. The frames of the inner shutter 4 (the upper frame 41, the lower frame 42, the vertical frame 43 arranged on the leading - edge side of the door, and the inner - meeting - frame 44 which is a vertical frame arranged on the trailing - edge side of the door) can be formed, for example, by extrusion - molding aluminum. The frames of the inner shutter 4 have a higher thermal conductivity compared to the face material 45 made of glass. Therefore, by reducing the width of the frames in the viewing direction and minimizing the exposure of the frames to the indoor side X2, the heat - insulation performance and dew - prevention performance of the sliding window 1 are enhanced.

[0015] As shown in FIG. 1, a crescent lock 44a for door closing is provided on the expected surface of the inner calling frame 44 of the inner shutter 4. As shown in FIGS. 2 to 4, on the vertical frame 43 disposed on the door tip side of the inner shutter 4, on the inner ends in the left - right direction of the frame body 40, there are provided indoor - side protruding portions 438 (ridge portions) that constitute a hand - holding portion.

[0016] As shown in FIG. 2, the vertical frame 33 and the outer calling frame 34 of the outer shutter 3 each have a composite structure in which resin frame materials 332, 342 are attached to the indoor side X2 of metal frame materials 331, 341. The vertical frame 43 and the inner calling frame 44 of the inner shutter 4 each have a composite structure in which resin frame materials 432, 442 are attached to the indoor side X2 of metal frame materials 431, 441.

[0017] Next, the structure related to the indoor - side protruding portion 438 that constitutes the hand - holding portion will be described. As shown in FIGS. 2 to 4, on the vertical frame 43 disposed on the door tip side of the inner shutter 4, there is provided an indoor - side protruding portion 438 that constitutes the hand - holding portion.

[0018] The indoor - side protruding portion 438 protrudes from the indoor - side X2 surface of the vertical frame 43 disposed on the door tip side of the inner shutter 4 toward the indoor side X2 and extends in the vertical direction. The vertical frame 43 disposed on the door tip side of the inner shutter 4 is formed with a small width in the finding direction. The vertical frame 43 disposed on the door tip side of the inner shutter 4 is composed of a combination of a metal frame material 431 and a resin frame material 432.

[0019] As shown in FIG. 2, in the vertical frame 43 formed by combining the metal frame material 431 and the resin frame material 432, on the inner side in the left - right direction of the vertical frame 43, there is formed a face - material swallowing portion 430 where the left - right ends of the face material 45 are disposed.

[0020] The metal frame member 431 is disposed on the outdoor side X1 of the vertical frame 43 disposed on the door tip side. The metal frame member 431 has a hollow portion 431a, a swing prevention member mounting frame 431b formed on the outer side in the left-right direction of the hollow portion 431a, and an outdoor side frame 431c formed on the outdoor side X1 on the inner side in the left-right direction of the hollow portion 431a. A swing prevention member 5 for suppressing the swing of the inner shutter 4 with respect to the vertical frame 24 is disposed on the swing prevention member mounting frame 431b.

[0021] As shown in FIG. 2, the resin frame member 432 is attached to the indoor side X2 of the metal frame member 431. The resin frame member 432 has a first hollow portion 433 formed on the inner side in the left-right direction, a second hollow portion 434 formed on the outer side in the left-right direction of the first hollow portion 433, and a T-shaped portion 435 formed at the end on the indoor side X2 of the first hollow portion 433 and having a T-shaped cross section. As shown in FIG. 2, the first hollow portion 433 and the second hollow portion 434 of the resin frame member 432 are provided on the indoor side surface, thereby blocking cold air from the outside and enhancing the heat insulation performance and dew prevention performance. A heat insulation space is formed by the T-shaped portion 435 and the grating channel 439 that holds the end portions on the vertical frame 43 side in the left-right direction of the face material 45 of the inner shutter 4, thereby enhancing the heat insulation performance and dew prevention performance.

[0022] As shown in FIG. 5, the first hollow portion 433 and the second hollow portion 434 extend in the vertical direction. A first hooking engagement portion 433a is formed on the surface of the end portion on the inner side in the left-right direction of the first hollow portion 433 on the outdoor side X1. A second hooking engagement portion 434a is formed on the surface of the end portion on the outer side in the left-right direction of the second hollow portion 434 on the outdoor side X1. The first hooking engagement portion 433a and the second hooking engagement portion 434a are hooked and engaged with the metal frame member 431 when the resin frame member 432 is attached to the metal frame member 431, as shown in FIG. 2.

[0023] The T-shaped portion 435 constitutes a portion on the indoor side X2 of the recessed portion 430 of the vertical frame 43. On the outdoor side X1 of the T-shaped portion 435, the end portions in the left-right direction of the face material disposed in the recessed portion 430 are disposed.

[0024] As shown in FIGS. 2 and 5, the T-shaped part 435 has an indoor-side left-right extending part 436 that extends inward in the left-right direction from the indoor-side end of the first hollow part 433, an outdoor-side protruding part 437 that protrudes toward the outdoor side X1 from the left-right inner end of the indoor-side left-right extending part 436, and an indoor-side protruding part 438 that protrudes toward the indoor side X2 from the left-right inner end of the indoor-side left-right extending part 436.

[0025] As shown in FIG. 5, the indoor-side left-right extending part 436 is formed in a plate shape extending in the vertical and left-right directions, and extends across the entire vertical range of the first hollow part 433.

[0026] The outdoor-side protruding part 437 is formed in a plate shape extending in the vertical and prospective directions. The outdoor-side protruding part 437 extends in the vertical direction with a length shorter than the vertical length of the indoor-side left-right extending part 436.

[0027] The indoor-side protruding part 438 is formed in a plate shape extending in the vertical and prospective directions. The indoor-side protruding part 438 extends in the vertical direction with a length shorter than the vertical length of the indoor-side left-right extending part 436 and longer than the vertical length of the outdoor-side protruding part 437. The indoor-side protruding part 438 constitutes a handhold part that a user can grasp when opening and closing the inner shutter 4.

[0028] The indoor-side protruding part 438 has a thickness in the left-right direction and is formed in a plate shape that protrudes toward the indoor side X2 and extends in the vertical direction. The indoor-side protruding part 438 constitutes a handhold part that can be grasped to perform an opening and closing operation when opening or closing the inner shutter 4. The indoor-side protruding part 438 extends along the vertical direction (longitudinal direction) of the inner calling frame 44.

[0029] In this embodiment, the vertical frame 43 is a frame with a small width in the finding direction. Therefore, even for a vertical frame 43 with a small width in the finding direction that does not have the width in the finding direction required when providing, for example, a concave part as a handhold part, the indoor-side protruding part 438 can be formed with a small width in the left-right direction inside the left-right direction of the vertical frame 43.

[0030] The outdoor protruding portion 437 and the indoor protruding portion 438 are formed by being notched so as to avoid the L-shaped angle 211 of the upper frame 21 and the L-shaped angle 221 of the lower frame 22 at the upper and lower ends of the vertical frame 43 disposed on the door tip side of the sash 4, as shown in FIG. 4.

[0031] Specifically, as shown in FIG. 5, at the upper and lower ends in the vertical direction (longitudinal direction) of the resin frame material 432 of the vertical frame 43, a notch processing surface 440 obtained by notching a part of the outdoor protruding portion 437 and a part of the indoor protruding portion 438 is formed.

[0032] Here, a procedure for performing notch processing at the upper and lower ends of the resin frame material 432 of the vertical frame 43 will be described. The resin frame material 432 is processed to notch the indoor protruding portion 438 at the upper and lower ends as in the processing steps of FIGS. 6 and 7.

[0033] First, starting from the state shown in the leftmost figure of FIG. 6 and the upper left figure of FIG. 7, as shown in the second figure from the left of FIG. 6 and the lower left figure of FIG. 7, at the upper and lower ends of the resin frame material 432, the outdoor protruding portion 437 is cut to perform a process of separating a substantially rectangular outdoor protruding portion separated piece 437a.

[0034] Specifically, as shown in the second figure from the left of FIG. 6 and the lower left figure of FIG. 7, the outdoor protruding portion 437 is cut at the upper and lower ends at the connection portion with the indoor protruding portion 438 along the cutting surface 438d in the left-right direction and the finding direction, and is cut at the cutting surface 437c along the horizontal plane in the prospective direction at the connection portion with the outdoor protruding portion 437.

[0035] Thereby, a process of separating a substantially rectangular outdoor protruding portion notched and separated piece 437a from the outdoor protruding portion 437 is performed. When the outdoor protruding portion 437 is cut to separate the substantially rectangular outdoor protruding portion separated piece 437a, when the resin frame material 432 is viewed from the inner side in the left-right direction of the sash 4, the outdoor protruding portion 437 and the indoor protruding portion 438 are formed in a stepped shape.

[0036] In this state, as shown in the second figure from the left in FIG. 6 and the lower left figure in FIG. 7, the cut surface 438d of the indoor-side protruding portion 438 of the resin frame member 432 faces the outdoor side X1, and the cut surface 437c of the outdoor-side protruding portion 437 of the resin frame member 432 faces upward or downward.

[0037] Next, from the state shown in the second figure from the left in FIG. 6 and the lower left figure in FIG. 7, as shown in the third figure from the left in FIG. 6 and the upper right figure in FIG. 7, the upper and lower ends of the indoor-side protruding portion 438 are cut to separate a substantially rectangular indoor-side protruding portion separated piece 438a.

[0038] Specifically, as shown in the third figure from the left in FIG. 6 and the upper right figure in FIG. 7, the indoor-side protruding portion 438 is cut at the upper and lower ends and at the cut surface 437b along the left-right direction and the up-down direction at the connection portion with the outdoor-side protruding portion 437.

[0039] Also, at a position a predetermined distance below the upper end of the indoor-side protruding portion 438 and at a position a predetermined distance above the lower end, it is cut at the cut surface 438b along the horizontal plane in the expected direction on the outdoor side X1, and it is cut along the cut surface 438c that slopes downward forward with respect to the horizontal plane in the expected direction on the indoor side X2. In this way, a substantially rectangular indoor-side protruding portion separated piece 438a is separated from the indoor-side protruding portion 438.

[0040] In this state, as shown in the third figure from the left in FIG. 6 and the upper right figure in FIG. 7, the cut surfaces 438b and 438c of the outdoor-side protruding portion 437 of the resin frame member 432 are exposed upward or downward, and the cut surface 437b of the outdoor-side protruding portion 437 is exposed on the indoor side X2. Here, since the cut surface 437b of the outdoor-side protruding portion 437 is exposed on the indoor side X2, the cut surface 437b of the outdoor-side protruding portion 437 is in a state where it can be visually recognized from the indoor side X2.

[0041] Next, from the state shown in the third figure from the left in FIG. 6 and the upper right figure in FIG. 7, as shown in the fourth figure from the left in FIG. 6 and the lower right figure in FIG. 7, at the inner ends in the left - right direction of the indoor - side left - right extending portion 436, the upper and lower ends in the longitudinal direction are cut to separate a substantially rectangular left - right inner separation piece 436b.

[0042] Specifically, as shown in the third figure from the left in FIG. 6 and the lower right figure in FIG. 7, at the upper and lower ends of the inner end in the left - right direction of the indoor - side left - right extending portion 436, the indoor - side protruding portion 438 is cut at the upper and lower ends and at the connection portion with the indoor - side left - right extending portion 436 along the cutting plane 436a along the prospective direction and the up - down direction, and is cut at the cutting plane 438e along the horizontal plane in the prospective direction at the connection portion with the indoor - side protruding portion 438.

[0043] In this state, as shown in the third figure from the left in FIG. 6 and the lower right figure in FIG. 7, the cutting plane 436a of the indoor - side left - right extending portion 436 of the resin frame member 432 is exposed to the inner side in the left - right direction, and the cutting planes 438b, 438c, 438e of the outdoor - side protruding portion 437 of the resin frame member 432 are exposed to the upper side or the lower side.

[0044] In this way, by notching the upper and lower ends of the resin frame member 432 of the vertical frame 43, a notched surface 440 can be formed. The notched surface 440 is composed of the cutting plane 436a of the indoor - side left - right extending portion 436, the cutting planes 438b, 438c, 438e of the outdoor - side protruding portion 437, the cutting plane 437c of the outdoor - side protruding portion 437, and the cutting plane 438d of the indoor - side protruding portion 438, as shown in FIG. 5. The cutting plane 436a of the indoor - side left - right extending portion 436 is a prospective surface facing the inner side in the left - right direction. The cutting planes 438b, 438c, 438e of the outdoor - side protruding portion 437 and the cutting plane 437c of the outdoor - side protruding portion 437 are surfaces facing the upper side or the lower side. The cutting plane 438d of the indoor - side protruding portion 438 is a finding surface facing the outdoor - side X1 and is not visible from the indoor side. In this embodiment, the notched surface 440 is composed of including the prospective surface (the cutting plane 436a of the indoor - side left - right extending portion 436). No finding surface facing the indoor side is formed on the notched surface 440.

[0045] Here, if we assume a case where the indoor-side protruding portion 438 is cut along the finding direction, the finding surface is exposed to the indoor side X2. On the other hand, in this embodiment, in the resin frame member 432, the cutout processed surface 440 is configured to include the prospective surface (the cut surface 436a of the indoor-side left-right direction extending portion 436). Therefore, a part of the cutout processed surface 440 (the cut surface 436a of the indoor-side left-right direction extending portion 436) becomes difficult to be visually recognized from the indoor side X2, and the cutout processed surface 440 can be made less conspicuous in the external view from the indoor side X2.

[0046] As described above, by cutting the upper and lower ends of the resin frame member 432, as shown in the right figure of FIG. 6 and the lower figure of FIG. 7, the cut surface 436a of the indoor-side left-right direction extending portion 436 of the resin frame member 432 constitutes a prospective surface that is exposed to the inner side in the left-right direction, and the cut surface 438d of the indoor-side protruding portion 438 of the resin frame member 432 constitutes a finding surface facing the outdoor side X1. Thereby, even when the upper and lower ends of the resin frame member 432 are notched, the cutout processed surface 440 can be formed in a state where there is no finding surface exposed to the indoor side X2. Therefore, the cutout processed surface 440 can be made less conspicuous.

[0047] According to this embodiment, the following effects are achieved. The shoji 4 of this embodiment is a shoji 4 including a frame body 40 having a vertical frame 43, and the vertical frame 43 is provided inside the frame body 40 and protrudes indoors and has an indoor-side protruding portion 438 that constitutes a hand-holding portion. Thereby, even when the width of the vertical frame 43 in the finding direction is reduced to enhance the heat insulation performance and the dew prevention performance, the opening and closing operation of the inner shoji 4 can be ensured. That is, by providing the indoor-side protruding portion 438 on the vertical frame 43 having a small width in the finding direction, the indoor-side protruding portion 438 can be configured as a hand-holding portion, and the opening and closing operation of the inner shoji 4 can be ensured. Therefore, it is possible to achieve both reducing the width of the vertical frame 43 in the finding direction and ensuring the opening and closing operation of the inner shoji 4.

[0048] In this embodiment, the indoor-side protrusion 438 is formed to extend along the longitudinal direction of the vertical frame 43. At the longitudinal end of the vertical frame 43, a notch processing surface 440 is formed by cutting out a part of the indoor-side protrusion 438. The notch processing surface 440 is composed of a prospective surface. Thereby, the notch processing surface 440 can be formed in a state where there is no exposed surface on the indoor side X2. Therefore, the notch processing surface 440 can be made less conspicuous. Thus, the design property can be improved.

[0049] As described above, a preferred embodiment of the present disclosure has been described. However, the present disclosure is not limited to the above-described embodiment and can be appropriately changed.

[0050] For example, in the above embodiment, the indoor-side protrusion 438 is formed to extend in a wide range in the vertical direction of the vertical frame 43. However, it is not limited thereto. For example, the indoor-side protrusion may be provided in a part of the vertical direction of the vertical frame. In that case, the indoor-side protrusion may be provided at one location or at a plurality of locations. Further, the indoor-side protrusion 438 does not have to be formed in a plate shape.
