Further, the invention according to claim 3 is the fitting according to claim 1, further comprising an engaging connection portion for connecting the pair of divided uprights by engagement during construction. The fixed connection portion connects the inner ends of the pair of divided uprights indoors, and the engaging connection portion connects the outer ends of the pair of divided uprights outdoors. Further, the invention according to claim 4 is the fitting according to claim 1, wherein each of the pair of divided uprights includes an edge holding portion for engaging and holding an edge at an outer end. A joint with a predetermined width is formed between the pair of edges engaged and held by the pair of divided uprights, and a joint cap is fitted into the joint.

Advantages of the Invention

[0006] According to the invention of claim 1, the fixed connection portion for connecting the pair of divided uprights includes a first connecting member fixed to one of the divided uprights and a second connecting member fixed to the other divided upright. Since the overlapping portion of the first connecting member and the second connecting member is connected with a screw, based on the dimensional settings of the first connecting member and the second connecting member, the connection interval between the pair of divided uprights and the width of the joint formed between the pair of divided uprights can be easily changed. Further, according to the invention of claim 2, the first connecting member and the second connecting member are engaged and held so as to be movable in the vertical direction and immovable in the left-right direction and the front-rear direction with respect to the divided upright, and then fixed with a screw. Therefore, the positional accuracy and fixing strength of the first connecting member and the second connecting member can be improved. Further, according to the invention of claim 3, it further includes an engaging and connecting portion for connecting a pair of split uprights by engagement during construction. The fixed connecting portion connects the indoor-side ends of the pair of split uprights, and the engaging and connecting portion connects the outdoor-side ends of the pair of split uprights. Therefore, not only can the pair of split uprights be reliably connected on the indoor side and the outdoor side, but also the connecting operation of the pair of split uprights can be performed on the indoor side. Further, according to the invention of claim 4, each of the pair of split uprights is provided with an edge retaining portion for engaging and retaining an edge at the outdoor-side end. A joint with a predetermined width is formed between the pair of edges engaged and retained by the pair of split uprights. Therefore, an upright with a joint can be configured. Further, since a joint cap is fitted into the joint, not only the waterproofness and dustproofness are improved, but also an arbitrary-color joint can be formed on the upright based on the color selection of the joint cap.

[0018] Next, the connection structure of the split post 45 will be described with reference to FIGS. 4 to 7.

[0019] A pair of split vertical members 45 are connected via a fixed connection part J1 and an engagement connection part J2 during construction. The fixed connection part J1 fixedly connects the indoor-side ends of the pair of split vertical members 45, and the engagement connection part J2 connects the outdoor-side ends of the pair of split vertical members 45 in an engaged state.

[0020] As shown in FIGS. 4 and 5, the fixed connection part J1 includes a first connection member 11 fixed to one of the split vertical members 45 and extending toward the other split vertical member 45, and a second connection member 12 fixed to the other split vertical member 45 and extending toward the one split vertical member 45. The first connection member 11 and the second connection member 12 fixed to each split vertical member 45 overlap in the front-rear direction and are connected by a screw N1 when connecting the split vertical members 45 to each other. Thereby, the indoor-side ends of the pair of split vertical members 45 are fixedly connected via the fixed connection part J1.

[0021] The first connection member 11 and the second connection member 12 of the present embodiment are formed of extruded members or bent members having a substantially L-shaped cross section, and have fixing parts 111, 121 fixed to the split vertical members 45 with screws N2, and extending parts 112, 122 extending in the left-right direction from one end in the front-rear direction of the fixing parts 111, 121 integrally. The extending parts 112, 122 overlap in the front-rear direction and are connected by a screw N1 when connecting the split vertical members 45 to each other. Therefore, the extending part 112 of the first connection member 11 and the extending part 122 of the second connection member 12 are formed with their positions shifted by the thickness of the extending parts 112, 122 in the front-rear direction.

[0022] The split vertical member 45 includes a connection member holding part 454 that engages and holds the first connection member 11 or the second connection member 12 so as to be vertically movable and immovable in the left-right and front-rear directions. The first connection member 11 and the second connection member 12 are fixed to the split vertical member 45 with screws N2 while being engaged and held by the connection member holding part 454.

[0023] The connecting member holding portion 454 is formed along the vertical direction at the indoor-side ends of the pair of split uprights 45 at the portions facing each other, and includes a concave groove 454a and a pair of protrusions 454c protruding from the groove side surface portion 454b of the concave groove 454a. The concave groove 454a engages and holds the fixing portions 111, 121 of the first connecting member 11 or the second connecting member 12 so as to be movable in the vertical direction and immovable in the front-rear direction, and the pair of protrusions 454c engage and hold the fixing portions 111, 121 of the first connecting member 11 or the second connecting member 12 so as to be immovable in the left-right direction between the groove bottom portion 454d of the concave groove 454a. Then, the fixing portions 111, 121 of the first connecting member 11 or the second connecting member 12 are fixed to the groove bottom portion 454d of the concave groove 454a via screws N2.

[0024] When connecting the pair of split uprights 45, a tool (not shown) is inserted through the indoor-side gap S1 formed between the pair of split uprights 45, and the extending portions 112, 122 of the first connecting member 11 and the second connecting member 12 are connected by screws N1. Thereafter, an indoor-side cap 13 is fitted into the gap S1, and the first connecting member 11, the second connecting member 12, and the screw N1 are concealed. Note that the second connecting member 12 of the present embodiment includes a cap holding portion 123 for engaging and holding the indoor-side cap 13.

[0025] As shown in FIGS. 4 and 6, the engagement connecting portion J2 includes an L-shaped engagement piece 455 protruding from the opposing surfaces of the pair of split uprights 45 and overlapping in the left-right direction when connecting the pair of split uprights 45, and an engagement member 14 fixed to one of the split uprights 45 by a screw N3. The engagement member 14 includes a U-shaped engagement connecting portion 141 that can engage with the engagement piece 455 overlapping in the left-right direction from the indoor side. When the engagement connecting portion 141 engages with the engagement piece 455 overlapping in the left-right direction, the movement of the pair of split uprights 45 in the separating direction is restricted, and the engagement connection state of the pair of split uprights 45 is maintained.

[0026] According to such a connection structure of the split mullion 45, after fixing the first connecting member 11 to one split mullion 45 and fixing the second connecting member 12 and the engaging member 14 to the other split mullion 45, the pair of split mullions 45 are abutted in a state where they are displaced in the front-rear direction (a state where the other split mullion 45 is displaced inward of the room). Then, when the front-rear positions of the pair of split mullions 45 are aligned, the engaging pieces 455 of each split mullion 45 are engaged with the engaging connection portion 141 of the engaging member 14 while overlapping in the left-right direction. Further, since the extending portions 112 and 122 of the first connecting member 11 and the second connecting member 12 also overlap in the front-rear direction, the extending portions 112 and 122 are connected to each other by a screw N1. As a result, the pair of split mullions 45 are connected in an engaged state with the outer ends on the outdoor side connected via the engaging connection portion J2 and the inner ends on the indoor side connected in a fixed state via the fixed connection portion J1.

[0027] Also, as shown in FIGS. 4 and 7, when connecting the pair of split mullions 45, a spacer 15 and a sealing material 16 are arranged in the outdoor gap S2 formed between the pair of split mullions 45. Further, a joint M5 having a predetermined width A is formed between the pair of edge pressing members 7A engaged and held by the edge pressing holding portions 453 of the pair of split mullions 45. A joint cap 17 is fitted into this joint M5. The fitted joint cap 17 is prevented from coming off by the edge pressing holding portions 453 of the pair of split mullions 45.

[0028] According to the present embodiment configured as described above, the fitting 1 including at least two rows of windows 1a, 1b, 1c arranged in the left-right direction, the mullion 2 arranged between the windows 1a, 1b, 1c includes a pair of split mullions 45 split in the left-right direction, and the pair of split mullions 45 are connected via the fixed connection portion J1 during construction. The fixed connection portion J1 includes a first connecting member 11 fixed to one split mullion 45 and extending toward the other split mullion 45, and a second connecting member 12 fixed to the other split mullion 45 and extending toward the one split mullion 45. The first connecting member 11 and the second connecting member 12 overlap in the front-rear direction and are connected by a screw N1. Therefore, based on the dimension settings of the first connecting member 11 and the second connecting member 12, the connection interval of the pair of split mullions 45 and the width of the joint M5 formed between the pair of split mullions 45 can be easily changed.

[0029] Further, one of the divided vertical members 45 includes a connecting member holding portion 454 that engages and holds the first connecting member 11 so as to be movable in the vertical direction and immovable in the left-right and front-rear directions. The first connecting member 11 held by the connecting member holding portion 454 is fixed to the one divided vertical member 45 with a screw N2. The other divided vertical member 45 includes a connecting member holding portion 454 that engages and holds the second connecting member 12 so as to be movable in the vertical direction and immovable in the left-right and front-rear directions. The second connecting member 12 held by the connecting member holding portion 454 is fixed to the other divided vertical member 45 with a screw N2. Therefore, the positional accuracy and fixing strength of the first connecting member 11 and the second connecting member 12 can be improved.

[0030] Further, the fitting 1 further includes an engaging connection portion J2 that connects the pair of divided vertical members 45 by engagement during construction. The fixed connection portion J1 connects the indoor-side ends of the pair of divided vertical members 45, and the engaging connection portion J2 connects the outdoor-side ends of the pair of divided vertical members 45. Therefore, not only can the pair of divided vertical members 45 be reliably connected indoors and outdoors, but also the connection work of the pair of divided vertical members 45 can be performed indoors.

[0031] Further, each of the pair of divided vertical members 45 includes an edge holding portion 453 that engages and holds an edge 7A at the outdoor-side end. A joint M5 with a predetermined width A is formed between the pair of edges 7A engaged and held by the pair of divided vertical members 45, and a joint cap 17 is fitted into the joint M5. Therefore, not only is the waterproofness and dustproofness improved, but also a joint M5 of any color can be formed on the vertical member 2 based on the color selection of the joint cap 17.

[0032] Further, in the fitting 1 of the present embodiment, not only the width dimension A of the joints M1 to M5 formed in the frame body 4 but also the width dimension B of the edges 7A and 7B are unified, so that a good appearance can be obtained.
