The second mating protrusion 78b sandwiches the lower end of the side wall 32 of the batten 3 between itself and the second side wall 72.

This section describes a construction method for fixing a batten 3 to a mullion 2 in a building fixture 10. The construction method for a continuous window batten in this disclosure is a construction method for fixing a batten 3 located on the interior side of the mullion 2 in the projection direction and extending vertically to a mullion 2 that connects the vertical frames 4 of a sash frame 1, and includes an interior wall 41, 71 that faces the batten 3 on the interior side, a first protrusion 43, 73 that is located vertically outward of the vertical end of the batten 3 and protrudes from the interior wall 41, 71 to the exterior side in the projection direction, and a second protrusion 43, 73. The process also includes 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 that extend vertically inward from the tips of the locking portions 44, 74 and form gaps 44a, 74a that extend vertically inward and open between the interior walls 41, 71, and then 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.

The upper cover member 40 and 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.

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

The lower end of the side wall 32 pressed into the gap 78a is engaged from the inside in the horizontal direction by the second locking portion 78, and is sandwiched between the second mating 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, horizontal and vertical directions relative to the batten 3.

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. With the upper end of the opposing wall 31 inserted into the gap 44a, the upper cover member 40 is positioned laterally because the side wall 42 is located laterally outward of 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. When the upper cover member 40 is not fixed vertically, it descends and the first protrusion 43 engages with the upper end of the batten 3 to attach it.

For the batten 3 to which the upper cover member 40 and 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 engagement 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 engagement 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.

The batten 3, whose second claws 34 engage with the first claws 27 and whose engagement walls 33 are in the fitting grooves 54e, is positioned and fixed in the horizontal and vertical directions relative to the mullion 2. The lower cover member 70, which is positioned and fixed in the horizontal, vertical, and vertical directions relative to the batten 3, is positioned and fixed in the horizontal and vertical directions relative to the mullion 2 via the batten 3. The upper cover member 40, whose third claws 47 engage with the first claws 27, is positioned and fixed in the horizontal and vertical directions relative to the mullion 2.

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 lower cover member 70 are positioned and fixed horizontally, vertically, and vertically relative to the mullion 2.

The upper cover member 40 that is not fixed vertically is slid upward relative to the batten 3, and the protruding wall 45 is fixed to the protruding wall 14d using double-sided tape, as shown in Figure 7. When the protruding wall 45 is fixed to the protruding wall 14d, the upper cover member 40 is positioned and fixed horizontally, vertically, and in the front direction relative to the mullion 2.

According to the end structure of the multi-window batten and the installation method for the multi-window batten of this embodiment, the second claw portion 34 of the batten 3 engages with the first claw portion 27 of the mullion 2, and the engaging wall 33 of the batten 3 engages with the mating walls 54c, 54d, 64g, 64h of the second vertical frames 52, 62, thereby fixing the mullion 2 and the batten 3 in place, eliminating the need to use a resin vertical frame specifically for multi-windows. Because there is no need to selectively use resin vertical frames for single windows and resin vertical frames for multi-windows, the production efficiency of the vertical frames 4 can be improved.

The batten 3 is not fixed to the mullions 2 with screws, but is fixed by the engagement between the second claw 34 and the first claw 27, and the engagement wall 33 and the mating walls 54c, 54d, 64g, and 64h, thereby reducing the amount of work required during construction.

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. Therefore, when the upper end of the opposing wall 31 of the batten 3 is inserted into the gap 44a from below, the upper cover member 40 can be attached to the batten 3 without screw fastening. Attaching the upper cover member 40 to the batten 3 without screw fastening reduces construction labor and improves design.

The first protrusion 43 on the upper cover member 40 closes the upper side of the gap 44a, so when the upper cover member 40 is lowered, the first protrusion 43 engages with the upper end of the opposing wall 31 of the batten 3, preventing it from falling.

The pair of third claws 47 on the upper cover member 40 engage with the pair of first claws 27 on the upright 2 in the forward direction, allowing the upper cover member 40 to be stably attached to the upright 2 in both the horizontal and forward directions.

The locking portion 74 of the lower cover member 70 has a mating protrusion 74b that protrudes toward the interior of the room. The lower end of the opposing wall 31 of the batten 3 is sandwiched between the mating protrusion 74b and the interior wall 71, allowing the batten 3 to be stably fixed.

The lower cover member 70 is positioned vertically at the same position as the first protrusion 73. It has a second protrusion 77 that protrudes laterally inward from the second side wall 72, and a second locking portion 78 that extends upward from the tip of the second protrusion 77 and locks onto the side wall 32 of the batten 3 from the horizontal inside. This allows for stable positioning of the opposing wall 31 as well as the side wall 32 of the batten 3 in the horizontal direction.

The second locking portion 78 has a second mating projection 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 projection 78b and the second side wall 72, allowing the batten 3 to be fixed more stably.
