[0034] When the engaging walls 33 are inserted into and engaged with the engaging grooves 54e, 64i, the batten 3 is positioned and fixed in the projection direction to the second vertical frames 52, 62. When the engaging walls 33 are inserted into and engaged with the engaging grooves 54e, 64i, the batten 3 is positioned and fixed in the projection direction to the mullions 2 via the second vertical frames 52, 62. When the pair of second claws 34 engage with the first claws 27 from outside the room, the batten 3 is positioned and fixed in the horizontal and projection directions relative to the mullions 2.

[0035] 2 and 6, the upper cover member 40 covers the upper end of the batten 3 from the indoor side. The upper end of the upper cover member 40 is located higher than the upper end of the batten 3. The lower end of the upper cover member 40 is located lower than the upper end of the batten 3. The upper cover member 40 has an indoor wall 41, a side wall 42, a first protrusion 43, a locking portion 44, a protruding wall 45, a vertical wall 46, and a pair of third claw portions 47.

[0036] The interior wall 41 is a flat plate facing the batten 3 on the interior side. The lateral dimension of the interior wall 41 is longer than the lateral dimension of the batten 3. The side walls 42 extend from both lateral ends of the interior wall 41 toward the exterior side. The side walls 42 are located on the lateral outer side of the batten 3. The side walls 42 cover the batten 3 from the lateral outer side. The side walls 42 support the batten 3 from the lateral outer side. The projecting wall 45 extends from the upper end of the interior wall 41 toward the interior side. As shown in Figure 7, the projecting wall 45 contacts the projecting wall 14d of the third upper frame 14 from below. The projecting wall 45 contacting the projecting wall 14d also includes the case where an adhesive or the like is interposed between the projecting wall 45 and the projecting wall 14d. The projecting wall 45 is fixed to the underside of the projecting wall 14d using double-sided tape. The vertical wall 46 extends upward from the end of the projecting wall 45 facing the interior of the room. The vertical wall 46 is located on the interior side of the projecting wall 14d. The vertical wall 46 covers the projecting wall 14d from the interior side of the room.

[0037] The first protrusion 43 protrudes from the interior wall 41 toward the exterior side in the projection direction. The first protrusion 43 extends horizontally. The horizontal end of the first protrusion 43 is connected to the side wall 42. The vertical position of the first protrusion 43 is located vertically outward from the vertical end of the batten 3. The vertical position of the first protrusion 43 is located above the upper end of the batten 3. When the protrusion wall 45 is fixed to the underside of the protrusion wall 14d, a vertical gap is formed between the first protrusion 43 and the batten 3.

[0038] The locking portion 44 extends vertically inward from the outdoor-side tip of the first protrusion 43. The locking portion 44 extends downward from the outdoor-side tip of the first protrusion 43. Multiple locking portions 44 are provided at intervals in the horizontal direction. Three locking portions 44 are provided. The locking portions 44 form a gap 44a between them and the indoor wall 41. The gap 44a extends vertically and opens downward. The first protrusion 43 closes the upper side of the gap 44a. The three locking portions 44 form a gap 44a that extends horizontally between two side walls 42 that are separated horizontally. The upper end of the opposing wall 31 of the batten 3 is inserted into the gap 44a from below so as to be slidable vertically. The locking portion 44 locks onto the opposing wall 31 from the outdoor side. When the projecting wall 45 is fixed to the underside of the projecting wall 14d, the locking portion 44 is locked to the opposing wall 31 from the outside of the room.

[0039] The pair of third claw portions 47 are arranged apart in the horizontal direction. The pair of third claw portions 47 are located above the upper end of the batten 3. The vertical position of the upper ends of the pair of third claw portions 47 is the same as the position of the upper ends of the first claw portions 27 on the mullions 2. As shown in Figure 8, the pair of third claw portions 47 protrude from the interior wall 41 towards the outside of the room toward the mullions 2. The third claw portions 47 engage with the first claw portions 27 in the forward direction. The third claw portions 47 engage with the first claw portions 27 from the outside of the room. The upper cover member 40 is formed of a resin material. The upper cover member 40 is an injection-molded body.

[0040] When the locking portion 44 locks onto the upper end of the opposing wall 31 of the batten 3 inserted from below into the gap 44a, the upper cover member 40 is positioned and fixed in the projection direction relative to the batten 3. When the protruding wall 45 is not fixed to the underside of the protruding wall 14d, the upper cover member 40 can descend downward by its own weight. Because the first protrusion 43 closes the upper side of the gap 44a into which the upper end of the opposing wall 31 is inserted, when the upper cover member 40 descends, the first protrusion 43 engages with the upper end of the opposing wall 31 from above. Because the first protrusion 43 engages with the upper end of the opposing wall 31, the upper cover member 40 can be prevented from falling. When the protruding wall 45 is fixed to the underside of the protruding wall 14d and the locking portion 44 locks onto the batten 3 from the outside, the upper cover member 40 is positioned and fixed in the projection direction relative to the batten 3 while being prevented from falling. When the pair of third claws 47 engage with the first claws 27 from outside the room, the upper cover member 40 is positioned and fixed in the horizontal and vertical directions relative to the uprights 2.

[0041] As shown in Figure 2, the lower cover member 70 covers the lower end of the batten 3 from the indoor side. The upper end of the lower cover member 70 is located higher than the lower end of the batten 3. The lower end of the lower cover member 70 is located lower than the lower end of the batten 3. As shown in Figure 9, the lower cover member 70 has an indoor wall 71, a second side wall 72, a first protruding portion 73, a locking portion 74, an inclined wall 75, a vertical wall 76, a second protruding portion 77, and a second locking portion 78.

[0042] The interior wall 71 is a flat plate facing the batten 3 on the interior side. The lateral dimension of the interior wall 71 is longer than the lateral dimension of the batten 3. The second side walls 72 extend from both lateral ends of the interior wall 71 toward the exterior side in the forward direction. As shown in FIG. 10, the second side walls 72 are located laterally outside the side walls 32 of the batten 3. The second side walls 72 cover the batten 3 from the lateral outside. The second side walls 72 support the batten 3 from the lateral outside. The inclined wall 75 extends gradually downward from the lower end of the exterior end of the second side wall 72 toward the interior side in the forward direction. As shown in FIG. 11, the inclined wall 75 contacts the inclined wall 16c of the second lower frame 16 from above. The inclined wall 75 contacting the inclined wall 16c also includes the case where an adhesive or the like is interposed between the inclined wall 75 and the inclined wall 16c. The inclined wall 75 is fixed to the upper side of the inclined wall 16c using double-sided tape. The vertical wall 76 extends downward from the end of the inclined wall 75 on the indoor side. The vertical wall 76 contacts the protruding wall 16d from the indoor side. The vertical wall 76 covers the protruding wall 16d from the indoor side.

[0043] The first protrusion 73 protrudes from the indoor wall 71 toward the exterior side in the forward direction. The vertical position of the first protrusion 73 is located vertically outward from the vertical end of the batten 3. The vertical position of the first protrusion 73 is located below the lower end of the batten 3. The first protrusion 73 supports the opposing wall 31 of the batten 3 from below.

[0044] The locking portion 74 extends vertically inward from the outdoor-side tip of the first protrusion 73. The locking portion 74 extends upward from the outdoor-side tip of the first protrusion 73. The locking portion 74 forms a gap 74a between the locking portion 74 and the indoor wall 71. The gap 74a extends vertically and opens upward. The first protrusion 73 closes the lower side of the gap 74a. The lower end of the opposing wall 31 of the batten 3 is inserted into the gap 74a from above so as to be slidable vertically. The locking portion 74 locks to the opposing wall 31 from the outdoor side. The locking portion 74 has an engaging protrusion 74b that protrudes toward the indoor side. The engaging protrusion 74b clamps the lower end of the opposing wall 31 of the batten 3 between the locking portion 74 and the indoor wall 71.

[0045] The second protrusions 77 protrude laterally inward from the left and right second side walls 72. The vertical positions of the second protrusions 77 are the same as those of the first protrusions 73. The second protrusions 77 support the side walls 32 of the batten 3 from below.

[0046] The second locking portion 78 extends upward from the laterally inner tip of the second protruding portion 77. The second locking portion 78 forms a gap 78a between itself and the second side wall 72. The gap 78a extends in the forward direction and opens upward. The second protruding portion 77 closes the lower side of the gap 78a. The lower end of the side wall 32 of the batten 3 is inserted into the gap 78a from above. The second locking portion 78 locks to the side wall 32 from the laterally inner side. The second locking portion 78 has a second mating protrusion 78b that protrudes laterally outward. The second mating protrusion 78b clamps the lower end of the side wall 32 of the batten 3 between itself and the second side wall 72.

[0047] The construction method for fixing the batten 3 to the mullions 2 in the building fixture 10 will be described. The construction method for the continuous window batten in the present disclosure is a construction method for fixing the batten 3 located on the room inside in the projection direction of the mullions 2 to the mullions 2 that connect the vertical frames 4 of the sash frames 1, and extending vertically, and includes an interior wall 41, 71 that faces the batten 3 on the room inside, first protruding parts 43, 73 that are located vertically outside the vertical end of the batten 3 and protrude from the interior wall 41, 71 to the room outside in the projection direction, and the first protruding parts 43, The method includes a step of inserting the vertical end of the batten 3 from the vertical inside into the gaps 44a, 74a of the upper cover member 40 and the lower cover member 70, each of which has locking portions 44, 74 extending vertically inward from the tip of 73 and forming gaps 44a, 74a that extend vertically inward and open between the interior walls 41, 71, and engaging the locking portions 44, 74 with the batten 3 from the outside of the room to cover at least one of the upper and lower ends of the batten 3.

[0048] An upper cover member 40 and a lower cover member 70 are attached to the batten 3. When attaching the lower cover member 70 to the batten 3, the lower ends of the opposing walls 31 and side walls 32 of the batten 3 are inserted into the gaps 74a and 78a of the lower cover member 70 and pushed downward. The lower ends of the opposing walls 31 and side walls 32 pushed into the gaps 74a and 78a, respectively, are positioned vertically in contact with the upper sides of the first protrusions 73 and second protrusions 77.

[0049] The lower end of the opposing wall 31 pressed into the gap 74a is locked from the outside of the room by the locking portion 74, and is sandwiched between the fitting protrusion 74b and the indoor wall 71. The lower cover member 70, whose lower end of the opposing wall 31 is pressed into the gap 74a, is positioned and fixed in the vertical and horizontal directions relative to the batten 3.

[0050] The lower end of the side wall 32 pressed into the gap 78a is locked from the inside in the horizontal direction by the second locking portion 78, and is sandwiched between the second fitting protrusion 78b and the second side wall 72. The lower cover member 70, with the lower end of the side wall 32 pressed into the gap 78a, is positioned and fixed in the vertical and horizontal directions relative to the batten 3. The lower cover member 70 is positioned and fixed in the vertical, front and horizontal directions relative to the batten 3.

[0051] When attaching the upper cover member 40 to the batten 3, the upper end of the opposing wall 31 of the batten 3 is inserted into the gap 44a of the upper cover member 40. The upper cover member 40, with the upper end of the opposing wall 31 inserted into the gap 44a, is positioned laterally because the side wall 42 is located laterally outward relative to the batten 3. When the protruding wall 45 is not fixed to the protruding wall 14d, the upper cover member 40 is not fixed vertically. The upper cover member 40 that is not fixed vertically descends, and the first protruding portion 43 engages with the upper end of the batten 3 and is attached.

[0052] For the batten 3 to which the upper cover member 40 and the lower cover member 70 are attached, the pair of second claws 34 are pushed toward the first claws 27 on the mullions 2 to engage them from the outside of the room. While engaging the second claws 34 with the first claws 27, the side walls 32 are elastically deformed in directions that move the engagement walls 33 laterally away from each other so that they face the openings of the fitting grooves 54e, and then the elastic deformation of the side walls 32 is released. By releasing the elastic deformation of the side walls 32, the engagement walls 33 are inserted into the fitting grooves 54e from the outside in the lateral direction. When engaging the second claws 34 on the batten 3 with the first claws 27 on the mullions 2, the third claws 47 on the upper cover member 40 are engaged with the first claws 27 on the mullions 2.

[0053] The batten 3, with the second claw portions 34 engaged with the first claw portions 27 and the engagement walls 33 in the fitting grooves 54e, is positioned and fixed in the horizontal and front directions relative to the mullions 2. The lower cover member 70, positioned and fixed in the horizontal, front and vertical directions relative to the batten 3, is positioned and fixed in the horizontal and front directions to the mullions 2 via the batten 3. The upper cover member 40, with the third claw portions 47 engaged with the first claw portions 27, is positioned and fixed in the horizontal and front directions relative to the mullions 2.

[0054] The lower cover member 70 that is not fixed vertically is moved upward together with the batten 3, and the inclined wall 75 is fixed to the inclined wall 16c using double-sided tape, as shown in Figure 11. When the inclined wall 75 is fixed to the inclined wall 16c, the batten 3 and the lower cover member 70 are positioned and fixed in the horizontal, front and vertical directions relative to the mullions 2.

[0055] The upper cover member 40 that is not fixed in the vertical direction is slid upward relative to the batten 3, and the projecting wall 45 is fixed to the projecting wall 14d using double-sided tape, as shown in Figure 7. When the projecting wall 45 is fixed to the projecting wall 14d, the upper cover member 40 is positioned and fixed in the horizontal, front and vertical directions relative to the mullions 2.

[0056] According to the multi-window batten fixing structure of this embodiment, the mullions 2 and batten 3 are fixed when the second claws 34 of the batten 3 engage with the first claws 27 of the mullions 2 and the engaging walls 33 of the batten 3 engage with the mating walls 54c, 54d, 64g, 64h of the second vertical frames 52, 62, so there is no need to use a resin vertical frame specifically for multi-windows. Because there is no need to selectively use a resin vertical frame for a single window or a resin vertical frame for a multi-window, the production efficiency of the vertical frames 4 can be improved.

[0057] The batten 3 is not fixed to the upright 2 with screws, but is fixed by the engagement between the second claw portion 34 and the first claw portion 27, and the engagement wall 33 and the mating walls 54c, 54d, 64g, 64h. This eliminates the need for work to fix the screws and the screws are not exposed, reducing the amount of work required during construction and improving the design.

[0058] The upper cover member 40, which covers the upper end of the batten 3 from the indoor side, is located above the upper end of the batten 3 and has a first protrusion 43 that protrudes from the indoor wall 41 toward the outdoor side in the forward direction, and a locking portion 44 that extends upward from the tip of the first protrusion 43 and forms a gap 44a that extends vertically between the indoor wall 41 and opens downward, so that when the upper end of the opposing wall 31 of the batten 3 is inserted from below into the gap 44a, the upper cover member 40 can be attached to the batten 3 without screw fixing. Because the upper cover member 40 is attached to the batten 3 without screw fixing, no work is required for screw fixing and the screws are not exposed, which reduces the number of steps during construction and improves the design.

[0059] Since the first protrusion 43 on the upper cover member 40 blocks the upper side of the gap 44a, when the upper cover member 40 is lowered, the first protrusion 43 engages with the upper end of the opposing wall 31 on the batten 3, preventing it from falling.

[0060] Since a pair of third claw portions 47 on the upper cover member 40 engage with a pair of first claw portions 27 on the upright 2 in the forward direction, the upper cover member 40 can be stably attached to the upright 2 in the horizontal and forward directions.

[0061] The locking portion 74 of the lower cover member 70 has an engaging protrusion 74b that protrudes toward the inside of the room, and the lower end of the opposing wall 31 of the batten 3 is sandwiched between the engaging protrusion 74b and the interior wall 71, so that the batten 3 can be stably fixed.

[0062] The lower cover member 70 has a second protrusion 77 that is positioned vertically in the same position as the first protrusion 73 and protrudes laterally inward from the second side wall 72, and a second engagement portion 78 that extends upward from the tip of the second protrusion 77 and engages with the side wall 32 of the batten 3 from the horizontal inside, so that the side wall 32 of the batten 3 can be stably positioned in the horizontal direction in addition to the opposing wall 31.

[0063] The second locking portion 78 has a second mating protrusion 78b that protrudes outward in the horizontal direction, and the lower end of the side wall 32 of the batten 3 is sandwiched between the second mating protrusion 78b and the second side wall 72, allowing the batten 3 to be fixed more stably.

[0064] While preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to these examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

[0065] For example, in the above embodiment, a configuration in which the mullions 2 are formed from a metal material is exemplified, but this configuration is not limited to this. A configuration in which a portion of the mullions 2 is formed from a resin material and other portions are formed from a metal material is also possible. In the above embodiment, a configuration in which the battens 3 are formed from a resin material is exemplified, but this configuration is not limited to this. A configuration in which the battens 3 are formed from a metal material is also possible. A configuration in which a portion of the battens 3 is formed from a resin material and other portions are formed from a metal material is also possible. [Explanation of symbols]
