Mode for Carrying Out the Invention

[0009] As an example of the fitting of the embodiment, an example of a window fixed to the inner peripheral surface of an opening of a building will be described with reference to the drawings.

[0010] The fitting of the embodiment is, as shown in FIG. 1, a window disposed in an opening B formed in a wall surface W of a building, and includes a frame member 1 fixed to the inner peripheral surface of the opening B, for example, the inner peripheral surface of a wooden lintel member, and a plurality (three in this embodiment) of shoji 2 disposed slidably inside the frame member 1. The frame member 1 of this embodiment has an upper frame member 11, a lower frame member 12, and left and right vertical frame members 13, 13.

[0011] The upper frame member 11 is made of a metal material such as an aluminum alloy. As shown in Fig. 2, it has a prospective wall portion 11a fixed to the upper inner peripheral surface B1 of the opening, and four finding wall portions 11b, 11c, 11d, 11e extending downward from the inner peripheral surface of the prospective wall portion 11a. Three upper guiding portions 11f, 11g, 11h for guiding the upper sides of the sliding doors 2, 2 are formed between the four finding wall portions 11b, 11c, 11d, 11e.

[0012] The upper frame member 11 is arranged such that the prospective wall portion 11a is along the upper inner peripheral surface B1 of the opening, and is fixed by fixing means b1, b1 such as screws at the upper guiding portions 11f, 11h on the indoor side and the outdoor side.

[0013] The lower frame member 12 is made of a metal material such as an aluminum alloy. As shown in Fig. 2, it has a prospective wall portion 12a fixed to the lower inner peripheral surface B2 of the opening, and an inner rail portion 12b, a middle rail portion 12c, and an outer rail portion 12d extending upward from the inner peripheral surface of the prospective wall portion 12a. On the inner rail portion 12b, the middle rail portion 12c, and the outer rail portion 12d of the lower frame member 12, there are formed wheel placement portions that are wider in the prospective direction at the upper part.

[0014] The lower frame member 12 is arranged such that the prospective wall portion 12a is along the lower inner peripheral surface B2 of the opening, and is fixed by fixing means b2, b2 such as screws between the inner rail portion 12b and the middle rail portion 12c, and between the middle rail portion 12c and the outer rail portion 12d.

[0015] The upper frame member 11 and the lower frame member 12 are provided with a plurality of ribs extending in the longitudinal direction on the outer peripheral surfaces of the prospective wall portions 11a, 12a, and are arranged at intervals from the vertical inner peripheral surface B3. At appropriate positions between the outer peripheral surfaces of the prospective wall portions 11a, 12a and the vertical inner peripheral surface B3, a heat-expandable foaming material that expands due to heat during a fire may be arranged as needed.

[0016] The vertical frame member 13 has the same configuration on the left and right sides, and includes a main vertical frame member (main frame member) 131 disposed along the longitudinal direction on the vertical inner peripheral surface B3 of the opening, a sub-vertical frame member (sub-frame member) 132 movably connected to the lower end portion of the main vertical frame member 131 in the longitudinal direction, and an inner peripheral member (cover member) 133 engaged with the inner periphery of the main vertical frame member 131. The vertical frame member 13 can be used as both the left and right vertical frames by rotating 180 degrees around the vertical axis, and is fixed to the vertical inner peripheral surface B3 of the opening with the upper and lower ends in contact with or close to the upper inner peripheral surface B1 and the lower inner peripheral surface B2 of the opening.

[0017] As shown in FIGS. 3(a), (b), (c), FIG. 4(a), FIG. 5, and FIG. 6(a), the main vertical frame member 131 has a prospective wall portion 131a and finding wall portions 131b, 131b extending in the inner peripheral direction from the indoor end and the outdoor end of the prospective wall portion 131a.

[0018] The main vertical frame member 131 is composed of a metal material such as an aluminum alloy and has a long main body portion 131A with a length dimension h131 shorter than the height dimension H of the opening B, and a resin covering portion 131B continuously provided at the longitudinal end portion of the main body portion 131A, which is the lower end portion in this embodiment. As a whole, it has a length dimension h13 approximately equal to the height dimension H of the opening B.

[0019] When the vertical frame member 13 is fixed to the opening, the upper end of the main body portion 131A of the main vertical frame member 131 is brought into contact with or close to the upper inner peripheral surface B1, and the lower end of the covering portion 131B is brought into contact with or close to the lower inner peripheral surface B2, so that the prospective wall portion 131a is arranged along the vertical inner peripheral surface B3 of the opening and is fixed by fixing means b3 such as screws.

[0020] Note that the covering portion 131B of the main vertical frame member 131 may have a prospective wall portion and finding wall portions on the indoor and outdoor sides similar to the main body portion 131A, but it only needs to have dimensions and shapes sufficient to cover the sub-vertical frame member 132 at least when viewed from the indoor side.

[0021] In addition, the means for continuously providing the covering portion 131B to the lower end of the main vertical frame member 131A is not limited. For example, an insertion portion along the inner peripheral surface of the lower end of the main body portion 131A may be provided at an upper portion of the covering portion 131B, and the insertion portion may be provided by adhering it inside the main body portion 131A or the like.

[0022] The main body portion 131A of the main vertical frame member 131 is provided with an engaging piece 131c that extends in the inner peripheral direction from the inner peripheral surface of the expected wall portion 131a and then bends to one side, and an engaging piece 131d that protrudes from the inner side surface of the expected wall portion 131b on one side. A engaged portion for engaging the inner peripheral member (cover material) 133 is formed by both engaging pieces 131c and 131d.

[0023] The engaging piece 131c and the engaging piece 131d of the main body portion 131A of the main vertical frame member 131 are notched in the lower region, preventing interference between the engaging pieces 131c and 131d and the secondary vertical frame member 132 when the secondary vertical frame member 132 is connected to the lower inner periphery of the main vertical frame member 131.

[0024] The main vertical frame member 131 has a long hole 131e that is long in the vertical direction formed in the found wall portion 131b that becomes the outdoor side when arranged at the opening B of the building. Note that the long hole 131e provided in the main vertical frame member 131 may be provided in the found wall portion 131b on the indoor side, or may be provided in both found wall portions 131b.

[0025] The secondary vertical frame member 132 is made of a metal material such as an aluminum alloy, and as shown in FIGS. 3(c), 4(b), 5, and 6(a), is arranged inside the main vertical frame member 131, and has an expected wall portion 132a along the expected wall portion 131a of the main vertical frame member 131, and expected wall portions 132b and 132b that extend in the inner peripheral direction from the indoor end and the outdoor end of the expected wall portion 132a and are along the found wall portions 131b and 131b of the main vertical frame member 131.

[0026] The secondary vertical frame member 132 has screw holes 132e formed in the finding wall portion 132b that becomes the outdoor side when disposed at the opening B of the building. As shown in FIGS. 4(c) and 5, it is disposed inside the primary vertical frame member 131, and a long hole 131e formed in the finding wall portion 131b on the outdoor side of the primary vertical frame member 131 and a screw hole 132e formed in the finding wall portion 132b on the outdoor side of the secondary vertical frame member 132 are fixed and connected by fixing means b13 such as screws.

[0027] The position of the fixing means b13 in the long hole 131e of the primary vertical frame member 131 is adjusted and fixed to a position where the length dimension of the vertical member formed by the primary vertical frame member 131 and the secondary vertical frame member 132 is the same as the height dimension H of the opening B. When the vertical frame member 13 is fixed to the opening, the lower end of the secondary vertical frame member 132 abuts or is close to the lower inner peripheral surface B2.

[0028] It is preferable that the lower end position of the secondary vertical frame member 132 and the lower end position of the covering portion 131B of the primary vertical frame member 131 are the same. However, depending on design errors or errors in the height dimension H of the opening B, the lower end of the secondary vertical frame member 132 may be connected so as to protrude from the lower end of the covering portion 131B.

[0029] Note that the secondary vertical frame member 132 may be attached to the primary vertical frame member 131 so as to be movable in the longitudinal direction so as to absorb the thermal expansion of the primary vertical frame member 131 during a fire, and the portion where the secondary vertical frame member 132 is attached is not limited to the lower end portion of the primary vertical frame member 131. Also, the end of the primary vertical frame member 131 to which the secondary vertical frame member 132 is attached is not limited to the end face portion of the primary vertical frame member 131, and may be a region near the end.

[0030] The inner peripheral member (cover material) 133 has a projected wall portion 133a, finding wall portions 133b, 133b extending in the outer peripheral direction from the indoor end and the outdoor end of the projected wall portion 133a, and engaging claws 133c, 133c provided at the outer peripheral ends of the finding wall portions 133b, 133b, as shown in FIGS. 3(a)(b), 5, and 6(b).

[0031] The inner peripheral member 133 is composed of a metal material such as an aluminum alloy and has a main body portion 133A having a length dimension h133 smaller than the length dimension h13 of the main vertical frame member 131, and resin-made end members (cap members) 133B fitted to the upper and lower end portions of the main body portion 133A.

[0032] The end members 133B fitted to the upper and lower end portions of the main body portion 133A protrude by a dimension corresponding to the difference between the dimension h133 of the main body portion 133A and the dimension h13 of the main vertical frame member 131, and as a whole, have a length dimension comparable to the length dimension h13 of the vertical frame member 13.

[0033] The resin-made end members 133B of the inner peripheral member 133 may be provided on both the upper and lower end portions of the main body portion 133A, or may be provided on either the upper end portion or the lower end portion.

[0034] Note that the dimension by which the resin-made end member 133B protrudes from the end of the main body portion 133A means the total amount of protrusion of the upper and lower end members 133B fitted to the upper and lower end portions of the main body portion 133A, and when provided on either the upper end portion or the lower end portion, means the amount of protrusion of the end member 133B provided on that one side.

[0035] Also, the overall dimension including the end member 133B of the inner peripheral member (cover member) 133 is preferably a length dimension comparable to the length dimension h13 of the main vertical frame member 131, but may be shorter than the length dimension h13 of the vertical frame member 13 due to design errors or the like.

[0036] In the inner peripheral member (cover member) 133, cutout walls 133b, 133b are cut from the outer peripheral side in the lower region of the main body portion 133A to form a notch portion 133f.

[0037] The inner peripheral member (cover member) 133 is engaged with the inner periphery of the main vertical frame member 131 by engaging engagement claws 133c, 133c from the inner peripheral side with respect to the engagement pieces 131c, 131d of the main vertical frame member 131. At this time, the inner peripheral member 133 can be accommodated inside the main vertical frame member 131 without interfering with the sub-vertical frame member 132 because the notch portion 133f is located on the inner peripheral side of the sub-vertical frame member 132 connected to the main vertical frame member 131.

[0038] Then, the vertical frame member 13 with the inner peripheral member 133 disposed on the inner peripheries of the main vertical frame member 131 and the sub-vertical frame member 132 has a housing portion 13a for housing the leading edge side of the shoji 2 on the side where the inner peripheral member 133 is not engaged in the prospective direction, as shown in FIGS. 3(a) and 7. The housing portion 13a is formed between the upper inner peripheral surface B1 and the lower inner peripheral surface B2 of the opening and is fixed to the vertical inner peripheral surface B3.

[0039] (Shoji) As shown in FIGS. 2 and 3(a), the shoji 2 of the present embodiment is formed by attaching a door wheel attachment member 22 to the lower side of a fireproof glass plate 20 such as heat-resistant crystallized glass. The shoji 2 is guided by upper guide portions 11f, 11g, 11h formed on the upper frame member 11 at its upper side, and the door wheels 22a of the door wheel attachment member 22 are guided by the inner rail portion 12b, the middle rail portion 12c, and the outer rail portion 12d of the lower frame member 12, and is slidably arranged. Note that the shoji 2 may be mounted with an upper side member 21 made of a resin material or the like at its upper side so as to be guided by the upper guide portions 11f, 11g, 11h of the upper frame member 11.

[0040] Among the plurality of shojis 2, the shojis 2 arranged at the left and right ends may have a handle portion 2a attached thereto. By providing the handle portion 2a, the shoji 2 can be opened and closed by holding the handle portion 2a.

[0041] Also, the shoji 2 may be provided with an engaging portion 2b for interlocking adjacent shojis 2 with each other. For example, as shown in FIG. 3(d), the shoji 2 may be provided with the engaging portion 2b by attaching a flat block-shaped member made of a resin material to the lower portions of the left and right ends of the surface facing the adjacent shoji 2 by fixing means b such as screws. By moving the shoji 2 at the left and right ends to the left and right, the engaging portions 2b, 2b of the adjacent shoji 2, 2 can engage with each other, and the adjacent shoji 2 can be interlocked.

[0042] The upper sides of the plurality of shoji 2 in the closed state are respectively covered by the finding wall portions 11b, 11c, 11d, 11e that constitute the upper guide portions 11f, 11g, 11h. The vertical sides on the door tip side of the shoji 2 arranged at the left and right ends abut or are close to the inner peripheral surface of the vertical frame member 13 and are arranged in the accommodation groove portion 13a of the vertical frame member 13 and covered from the indoor and outdoor sides.

[0043] (Function and Effect of the Fittings of the Present Embodiment) The fittings of the present embodiment cover the indoor and outdoor surfaces of the outer periphery of the shoji made of a fire-resistant glass plate with a metal frame member, making it difficult to form a passage for flames indoors and outdoors and enabling the maintenance of fire prevention performance.

[0044] And in the event of a fire, elongation is likely to occur in the metal frame member, particularly the vertically long vertical frame member 13, and the fittings may be damaged due to this elongation. However, in the fittings of the present embodiment, since the vertical frame member 13 is formed by movably connecting a metal sub-vertical frame member 132 below the metal main vertical frame member 131, even if the vertical frame member 13 elongates due to heat during a fire, as shown in FIGS. 4(d), 8, and 9, the fixing means b13 connecting the main vertical frame member 131 and the sub-vertical frame member 132 shifts within the long hole 131e of the main vertical frame member 131, so that the connecting portion moves and the elongated portion of the main vertical frame member 131 can be absorbed. Therefore, during a fire, it is possible to suppress the destruction of the fittings due to the elongation of the vertically long vertical frame member 13 and suppress the communication between the indoor and outdoor.

[0045] Moreover, since the main vertical frame member 131 is provided with a resin covering portion 131B at the end of the metal main body portion 131A, it prevents the exposure of the sub-vertical frame member 132 arranged inside the main vertical frame member 131 during normal times, and during a fire, it does not hinder the absorption of thermal expansion by melting and the main vertical frame member 131 and the sub-vertical frame member 132.

[0046] In addition, for the fitting of this embodiment, since the inner peripheral member (cover member) is arranged inside the inner periphery of the main vertical frame member 131 of the vertical frame member 13, it is possible to protect the inner periphery of the vertical frame member 13 other than the accommodation portion 13a for housing the leading edge side of the shoji 2, and it is possible to protect the inner peripheral surface of the vertical frame member 13 where the shoji 2 is not arranged and the fixing portion for fixing the vertical frame member 13 with screws or the like. Furthermore, by forming a hollow portion with the main vertical frame member 131 and the inner peripheral member (cover member) 933, it is possible to protect the accommodation portion 13a during a fire.

[0047] And, since the end portion of the inner peripheral member 133 of this embodiment is provided with an end member 133B made of resin, even if the inner peripheral member 133 expands due to heat during a fire at the inner peripheral position of the main vertical frame member 131, as shown in FIGS. 8 and 9, the end member 133B melts and can absorb the expansion of the inner peripheral member (cover member) 133. Therefore, it is possible to suppress the destruction of the fitting due to the expansion of the inner peripheral member (cover member) 133 and suppress the communication between the indoor and outdoor areas.

[0048] -Other Embodiments- The upper frame member and the lower frame member are not limited as long as they have a fixing portion for fixing to the inner peripheral surface of the opening portion and a guiding portion for guiding the upper and lower portions of the shoji. In addition, the cross-sectional shape of the left and right vertical frame members is not limited as long as a visible wall portion (accommodation portion) for covering the leading edge of the shoji from the indoor and outdoor areas is formed.

[0049] Furthermore, the materials of the upper frame member, the lower frame member, and the vertical frame member are not particularly limited for the non-combustible portions of the upper frame member, the lower frame member, and the vertical frame member, such as metal materials made of stainless steel or aluminum, and other flame-retardant materials.

[0050] Note that the frame member configuration including the main frame member, the sub-frame member, and the inner peripheral member shown in the above embodiment is not limited to the vertical frame member, and can also be adopted for the horizontal frame member. The above embodiments do not limit the invention described in the claims, and it goes without saying that they are treated as examples.
