Summary of the Invention

Problems to be Solved by the Invention

[0004] There may be an error between the designed dimensions and the actual dimensions at the construction site of the opening for installing the window sash. Alternatively, there may be an error between the designed dimensions and the manufactured dimensions in the window sash itself or the components connecting the window sashes. Therefore, dimensional confirmation and fine adjustment of the installation position are performed at the construction site.In Patent Document 1, it is necessary to attach components for position adjustment, which is time-consuming.

[0005] The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a continuous window mullion structure and a method for adjusting errors of continuous windows that can easily adjust dimensional errors at the construction site when providing continuous windows in a building opening.

Means for Solving the Problems

[0006] A continuous window mullion structure according to one aspect of the present disclosure comprises a plurality of sashes, each having a panel supported by a frame and arranged in a line in the width direction; a mullion provided between the frames of adjacent sashes and connecting the adjacent frames; a locking piece formed on the frame; and an adjustment part formed to protrude from the side of the mullion so as to be insertable into the locking piece, and for adjusting the widthwise position of the mullion relative to the vertical frame of the frame, wherein the widthwise position of the mullion relative to the vertical frame is determined by the widthwise position of the locking piece within the adjustment part. A method for adjusting the error of a series of windows according to one aspect of the present disclosure involves arranging a sash, in which a panel is supported by a frame, next to a mullion, arranging a locking piece provided on the vertical frame of the frame within an adjustment portion that protrudes outward in the width direction from the side surface of the mullion, adjusting the position of the locking piece in the width direction within the adjustment portion to match the width dimension of the opening in which the sash is installed, and fixing the positioned mullion to the vertical frame.

[0008] (First Embodiment) An embodiment of the continuous window unit 100 will be described below with reference to the drawings. Figures 2 to 13 are diagrams of the AA cross-section shown in Figure 1. The continuous window unit 100 is installed by connecting a plurality of window sashes 110, 120 in an opening in a building. Hereinafter, the window sash 110 will be referred to as "sash". As shown in Figures 2 and 3, the continuous window unit 100 comprises a plurality of sashes 110, 120 and a mullion 1. The sashes 110, 120 have panels 101, 102 housed and fixed within a frame 2. The panels 101, 102 are, for example, double-glazed glass. Each panel may be single-glazed or double-glazed glass. The continuous window unit 100 is composed of two or more sashes arranged side by side, with a mullion 1 provided between adjacent sashes. As an example, an example in which two sashes 110, 120 are arranged side by side is shown, but the number of panels in the continuous window unit 100 is not limited to the illustrated example.

[0009] In the following explanation, the thickness direction of panels 101 and 102 will be referred to as the indoor-outdoor direction Y. Of the directions perpendicular to the indoor-outdoor direction Y, the vertical direction will be referred to as the longitudinal direction Z, and the horizontal direction perpendicular to both the indoor-outdoor direction Y and the longitudinal direction Z will be referred to as the width direction X.

[0010] Frame 2 comprises a pair of vertical frames 2A and 2B, an upper frame 2C, and a lower frame 2D. As shown in Figure 1, the pair of vertical frames 2A and 2B, the upper frame 2C, and the lower frame 2D are formed in a rectangular shape. Frame 2 is a molded material made of a metal material such as an aluminum alloy mold. The upper frame 2C and lower frame 2D may sometimes be referred to as horizontal frames 2C and 2D.

[0011] The horizontal frames 2C and 2D are positioned between the pair of vertical frames 2A and 2B. The longitudinal ends of the horizontal frames 2C and 2D are attached to the pair of vertical frames 2A and 2B.

[0012] In the following description, when viewing the sashes 110 and 120 from the indoor side I to the outdoor side O among the pair of vertical frames 2A and 2B, the left vertical frame of the panel 101 is described as the first vertical frame 2A, and the right vertical frame is described as the second vertical frame 2B. The first vertical frame 2A and the second vertical frame 2B are arranged side by side in the width direction X.

[0013] The vertical frames 2A and 2B include a hollow portion 21, a panel support portion 22, a locking piece 23, and a fixed portion 24. The hollow portion 21 has a substantially rectangular horizontal cross-sectional shape and is arranged on the outdoor side O. The panel support portion 22 is formed to protrude from the side surface 211 in the width direction X of the hollow portion 21. The panel support portion 22 has a shape in which the ends in the width direction X of the panels 101 and 102 can be inserted and held.

[0014] The locking piece 23 is a plate-like piece protruding toward the indoor side O from the indoor side O surface 212 of the hollow portion 21. The locking piece 23 extends along the indoor-outdoor direction Y. The locking piece 23 has a first surface 231 on the side of the panel support portion 22 and a second surface 232 on the side opposite to the first surface 231 in the width direction X. The second surface 232 is a surface facing the side surface 11 of the stile 1.

[0015] The fixed portion 24 is a portion for fixing the vertical frames 2A and 2B to the stile 1 with screws 90. The fixed portion 24 is a flat plate portion extending in the width direction X from the indoor side I ends of the vertical frames 2A and 2B. The fixed portion 24 has screw holes.

[0016] A rib 25 protruding and extending in the indoor-outdoor direction Y is formed in the vicinity of the fixed portion 24. The rib 25 is substantially equal in position in the width direction X to the locking piece 23. The rib 25 can guide the position of the vertical frames 2A and 2B with respect to the stile 1 in the same manner as the locking piece 23. There is a gap in the indoor-outdoor direction Y between the locking piece 23 and the rib 25. The rib 25 is not an essential component.

[0017] A contact portion 213 is provided at the indoor side O end of the hollow portion 21. The contact portion 213 extends along the width direction X from the hollow portion 21. The contact portion 213 is not an essential component.

[0018] The mullion 1 is a profile made of a metal material such as an aluminum alloy. The mullion 1 is a long member arranged along the vertical direction Z. The mullion 1 comprises a main body 4, an adjustment part 3, a fixing part 6, and a cover locking part 7. The main body 4 is a roughly rectangular hollow section. The main body 4 is divided into two sections in the indoor-outdoor direction Y by a partition wall 45. The main body 4 consists of an inner body 4a and an outer body 4b arranged side by side in the indoor-outdoor direction Y. The main body 4 is formed over approximately the entire length in the vertical direction Z, which is the length direction of the mullion 1. The outer body 4b is positioned between panels 101 and 102. The inner body 4a is positioned to protrude further towards the indoor side I than panels 101 and 102.

[0019] The sides of the outer body 4b in the width direction X are referred to as the lateral sides 11. The lateral sides 11 are planes that align with the indoor-outdoor direction Y. The outer surface 15 of the outer body 4b, which is located on the outdoor side O, is a plane that aligns with the width direction X.

[0020] The adjustment section 3 is provided on the side surface 11. In this embodiment, a pair of adjustment sections 3 are provided on the two side surfaces 11 of the outer body 4b. The pair of adjustment sections 3 are provided so as to be symmetrical with respect to the center line in the width direction X of the mullion 1.

[0021] The adjustment section 3 has a substantially L-shaped horizontal cross-section, as shown in Figures 2 and 3, for example. The adjustment section 3 includes a support section 31 and a positioning section 32. The support section 31 protrudes from the lateral surface 11 in the width direction X. The positioning section 32 extends from the protruding end 311 of the support section 31 along the indoor-outdoor direction Y towards the outdoor side O. As shown in Figure 5, the adjustment section 3 has a bottom surface 33 to which the ends 235 of the locking pieces 23 of the vertical frames 2A and 2B abut. The bottom surface 33 is a plane along the width direction X. For example, the adjustment section 3 is a groove with a substantially U-shaped horizontal cross-section. The dimension L31 between the inner surface 321 and the lateral surface 11 in the width direction X is longer than the thickness T23 of the locking piece 23. Therefore, when the locking piece 23 is positioned within the adjustment section 3, a gap is formed between the inner surface 321 and the lateral surface 11 that allows the locking piece 23 to move in the width direction X. This gap is for adjusting for errors during construction. The end of the locking piece 23 abuts against the support portion 31. The support portion 31 supports the locking piece 23. The inner surface 321 is an example of a positioning surface.

[0022] The adjustment section 3 is shown as an example of a roughly L-shaped form, but is not limited to this shape. The positioning section 32 only needs to have an inner surface 321 facing at least the lateral surface 11 that is a plane along the indoor-outdoor direction Y. The positioning section 32 only needs to have a groove formed that opens along the indoor-outdoor direction Y into which the locking piece 23 can be inserted.

[0023] The fixing part 6 is the part that fixes the part to be fixed 24. The fixing part 6 has an insertion hole 61 that penetrates in the indoor-outdoor direction Y. The insertion hole 61 is sized to allow a screw 90 to be inserted. Figure 6 is a partial cross-sectional view of the mullion 1 along the line C6-C6 shown in Figure 2. As shown in Figure 6, the insertion hole 61 is an elongated hole that is long in the width direction X. The opening dimension of the insertion hole 61 in the width direction X is greater than or equal to the length of dimension L31. As a result of the insertion hole 61 being an elongated hole, adjustment is possible even after installation. A cover locking part 7 is provided at the end of the fixing part 6 in the width direction X. The cover locking part 7 protrudes from the end of the part to be fixed in the width direction X towards the indoor side I along the indoor-outdoor direction Y.

[0024] The structure of the continuous window unit 100 will now be described. The continuous window unit 100 is installed to close off an opening in a building. As shown in Figures 2 and 3, a mullion 1 is provided between two or more adjacent sashes 110, 120 in the width direction X. The outer body 4b is sandwiched between a pair of vertical frames 2A, 2B. The fixed parts 24 of the vertical frames 2A, 2B abut against the fixed part 6 of the mullion 1, and the locking piece 23 is locked to the adjustment part 3. The end 235 of the locking piece 23 abuts against the bottom surface 33. The contact parts 213 of the vertical frames 2A, 2B abut against the outer surface 15.

[0025] The mullion 1 and the vertical frames 2A and 2B are fixed together by a screw 90 passing through in the thickness direction while the fixing part 6 of the mullion 1 and the fixed parts 24 of the vertical frames 2A and 2B are in contact. The inner body 4a of the mullion 1 is covered from the room side O by the mullion cover 8. The mullion cover 8 is attached by locking the locking end 81 of the mullion cover 8 into the cover locking part 7.

[0026] Next, the continuous window mullion structure and the method for adjusting the tolerance of the continuous windows will be described. The continuous window units 100 are manufactured so that they can be installed at a predetermined pitch. However, the dimensions of the building opening and the dimensions of the sashes 110 and 120 may differ slightly from the design dimensions due to manufacturing tolerances and the dimensions of the opening at the construction site. Therefore, fine adjustments are made at the construction site so that the dimensions of the continuous window units 100 match the actual opening dimensions. Fine adjustments may be made after assembling the continuous window units 100 on a flat surface such as the floor at the construction site and then adjusting them to the dimensions of the building opening, or they may be made while temporarily installing them in the opening. The mullion 1 allows for fine adjustment of the width X dimension of the sashes 110 and 120.

[0027] First, when installing multiple windows, several windows are connected while lying flat, and then temporarily installed in the building's opening. After temporary installation, the dimensions are remeasured to confirm that they are correct. If the dimensions are off at this time, they may be removed and the installation redone. Because the insertion hole 61 is an elongated hole, even after temporary installation in the building's opening, fine adjustments can be easily made within the range of the elongated hole's length. The vertical frames 2A and 2B are positioned next to the mullion 1, and the locking piece 23 is inserted into the adjustment section 3. At this time, the rib 25 contacts the side surface 11, allowing the vertical frames 2A and 2B to be smoothly attached to the mullion 1. When the locking piece 23 is inserted into the adjustment section 3, the fixed part 24 abuts against the fixed part 6, and the vertical frames 2A and 2B are temporarily locked to the mullion 1. Next, the position of the mullion 1 in the width direction X relative to the vertical frames 2A and 2B is adjusted to match the width direction X dimension of the opening at the construction site. Specifically, the mullion 1 is moved in the width direction X to adjust the position of the locking piece 23 in the width direction X within the adjustment section 3.

[0028] Specifically, as shown in Figure 5, the dimension L31 between the positioning part 32 and the lateral side surface 11 is set based on the thickness of the locking piece 23, i.e., the dimension T23 in the width direction X. When the locking piece 23 is positioned and locked in the adjustment part 3, a gap S is created in the groove of the adjustment part 3. For example, when the positioning part 32 is inserted into the adjustment part 3, the gap S in the adjustment part 3 is set to 1.0 mm. That is, dimension L31 is 1.0 mm larger than the thickness dimension T23 of the locking piece 23. After inserting the locking pieces 23 of the vertical frames 2A and 2B into the adjustment part 3 of the mullion 1, the locking pieces 23 are brought into contact with the positioning part 32 of the adjustment part 3 or the lateral side surface 11 of the main body 4. Depending on the position of the locking piece 23 in the adjustment part 3, the dimension X in the width direction of the continuous window unit 100 can be adjusted in multiple stages. For example, as shown in Figure 2, when the first surfaces 231 of a pair of locking pieces 23 are in contact with the inner surface 321 of the positioning part 32, the width X dimension of the connected window unit 100 is the longest. As shown in Figure 3, when the second surfaces 232 of a pair of locking pieces 23 are in contact with the lateral surface 11, the width X dimension of the connected window unit 100 is the shortest. As shown in Figure 4, when the second surface 232 of the locking piece 23 of the first vertical frame 2A is in contact with the lateral surface 11, and the first surface 231 of the locking piece 23 of the second vertical frame 2B is in contact with the inner surface 321, the width X dimension of the connected window unit 100 can be made 1.0 mm longer than the length shown in Figure 3. Alternatively, the second surface 232 of the locking piece 23 of the second vertical frame 2B may be in contact with the lateral surface 11, and the first surface 231 of the locking piece 23 of the first vertical frame 2A may be in contact with the inner surface 321. The lateral surface 11 and the inner surface 321 are examples of the first and second ends of the adjustment section.

[0029] For example, as shown in Figure 3, when the second surfaces 232 of the locking pieces 23 of the first vertical frame 2A and the second vertical frame 2B are brought into contact with the horizontal surface 11, the width X dimension of the window unit 100 is set to the same dimension as the standard module. If the measured dimensions of the opening at the construction site are slightly larger than the standard module, as shown in Figure 4, when the second surface 232 of the locking piece 23 of the first vertical frame 2A is brought into contact with the horizontal surface 11, and the first surface 231 of the locking piece 23 of the second vertical frame 2B is brought into contact with the inner surface 321, the width X dimension of the window unit 100 can be made 1.0 mm longer. Alternatively, as shown in Figure 2, when the first surfaces 231 of the locking pieces 23 of the first vertical frame 2A and the second vertical frame 2B are brought into contact with the inner surface 321, the width X dimension of the window unit 100 can be made 2.0 mm longer than the standard module. For example, the longest dimension in the width direction X of the continuous window unit 100 may be set as the standard module, and the configuration may be such that the dimension in the width direction X can be shortened at the construction site. Since the insertion hole 61 of the fixing part 6 is an elongated hole, the relative position in the width direction X between the fixing part 6 and the fixing part 24 can be adjusted when positioning with the screw 90 lightly screwed into the screw hole of the fixing part 24.

[0030] After adjusting the positions of the first vertical frame 2A and the second vertical frame 2B, the fixing part 6 and the fixed part 24 are fixed with screws 90, thereby fixing the vertical frames 2A and 2B to the mullion 1. Through position adjustment and fixing, the distance L2 in the width direction X of the vertical frames 2A and 2B is positioned to a predetermined length. If there are three or more sashes, the above method is repeated sequentially.

[0031] According to the continuous window unit 100 and continuous window mullion structure of this embodiment, the width dimension X of the continuous window unit 100 can be easily adjusted by inserting the locking pieces 23 of the vertical frames 2A and 2B between the adjustment part 3 and the horizontal side surface 11, and bringing one of the surfaces of the locking piece 23 into contact with the inner surface 321 or the horizontal side surface 11.

[0032] According to the continuous window unit 100 and continuous window mullion structure of this embodiment, the mullion 1 is provided with two adjustment parts 3, and the positions of the pair of vertical frames 2A and 2B in the width direction X can be positioned respectively. As a result, the width direction X dimension of the continuous window unit 100 can be adjusted in multiple stages.

[0033] According to the continuous window unit 100 and continuous window mullion structure of this embodiment, since the mullion 1 is equipped with an adjustment part 3, the position in the width direction X can be adjusted at any point in the joint between the vertical frames 2A, 2B and the mullion 1. In the case of a continuous window unit 100 that has multiple mullions 1, the range in which the length in the width direction X of the continuous window unit 100 can be adjusted becomes larger.

[0034] (Second embodiment) Referring to Figures 7 to 10, the connected window unit 100A and the connected window mullion structure according to the second embodiment will be described. In the following description, components common to those already described will be denoted by the same reference numerals, and redundant explanations will be omitted. The connected window unit 100A according to this embodiment differs from that of the first embodiment in the shape of the mullion 1A.

[0035] The mullion 1A has an inclined surface 341 formed on the outdoor-side end 34 of the positioning portion 32 of the adjustment portion 3. Specifically, the inclined surface 341 is formed on the outdoor-side end 34 of the inner surface 321 such that the thickness in the width direction X of the positioning portion 32 becomes thinner towards the end 34. The end 34 is an example of an insertion end.

[0036] The mullion 1A further has a reinforcing portion 29. The reinforcing portion 29 is provided to reinforce the rigidity of the mullion 1A. The method of attaching the vertical frames 2A and 2B to the mullion 1A and the method of positioning them are the same as in the first embodiment.

[0037] According to the continuous window unit 100A and continuous window mullion structure of this embodiment, the locking pieces 23 of the vertical frames 2A and 2B are positioned between the positioning piece 32 of the adjustment piece 3 and the horizontal side surface 11, and by bringing one of the surfaces of the locking piece 23 into contact with the inner surface 321 or the horizontal side surface 11, the width dimension X of the continuous window unit 100 can be easily adjusted.

[0038] According to the continuous window unit 100A and continuous window mullion structure of this embodiment, the position of the mullion 1A in the width direction X relative to the vertical frames 2A and 2B can be easily adjusted by bringing the first surface 231 or the second surface 232 of the locking piece 23 into contact with the mullion 1A. Furthermore, since an inclined surface is formed on the inner surface 321 of the positioning part 32, the dimension L31 becomes larger at the end 34, making it easier to insert the locking piece 23.

[0039] (Third embodiment) The continuous window unit 100B and the continuous window mullion structure according to the third embodiment will be described with reference to Figures 11 and 12. At least one adjustment unit 3 is provided on the mullion 1. As shown in Figures 11 and 12, even if the adjustment unit 3 is provided on only one side surface 11 of the main body 4, the width dimension X of the continuous window unit 100 can be adjusted. In this embodiment, as shown in Figure 11, the width dimension X can be adjusted in two stages: a position where the first surface 231 of the locking piece 23 is in contact with the inner surface 321 of the positioning piece 32, and as shown in Figure 12, a position where the second surface 232 of the locking piece 23 is in contact with the side surface 11.

[0040] According to the continuous window unit 100B and continuous window mullion structure of this embodiment, the width dimension X of the continuous window unit 100 can be easily adjusted by inserting the locking pieces 23 of the vertical frames 2A and 2B between the positioning piece 32 of the adjustment piece 3 and the horizontal side surface 11, and bringing one of the surfaces of the locking piece 23 into contact with the inner surface 321 or the horizontal side surface 11.

[0041] (Fourth embodiment) The window unit 100C and window mullion structure according to the fourth embodiment will be described with reference to Figure 13. The window unit 100 may also be provided with spacers 5. As shown in Figure 13, in this embodiment, a spacer 5 is attached to one side of the locking piece 23 in advance. The spacer 5 is a flat plate member. The thickness of the spacer 5 is set to a dimension where the sum of the thickness of the spacer 5 and the thickness of the locking piece 23 is approximately equal to the dimension L31. The position where the first surface 231 of the locking piece 23 contacts the inner surface 321 of the positioning part 32 is a dimension that conforms to a standard module. When the opening dimensions of the installation site match the standard module, as a result of providing the spacer 5, when the locking piece 23 is inserted, the locking piece 23 contacts the inner surface 321 via the spacer 5, and a window unit 100 that conforms to the standard module can be assembled without any adjustment work. On the other hand, if the width X dimension of the opening in the building is smaller than the standard module, one or both spacers 5 can be removed at the construction site, and the width X dimension can be adjusted in the same manner as in the first embodiment. Spacer 5 is provided adjacent to locking piece 23. Spacer 23 may also be provided on positioning portion 32.

[0042] In the example shown in Figure 13, spacers 5 are also attached to the rib 25 and the reinforcing part 29. By providing spacers 5 to the rib 25 and the reinforcing part 29, alignment can be easily achieved when locking the mullion 1 with the vertical frames 2A and 2B. If the spacers 5 on the locking piece 23 are removed during construction, the spacers 5 on the rib 25 and the reinforcing part 29 should also be removed.

[0043] According to the continuous window unit 100C, continuous window mullion structure, and continuous window error adjustment method of this embodiment, a standard module continuous window unit 100 can be easily assembled. In addition, by removing the spacer 5, the width dimension X of the continuous window unit 100 can be easily adjusted, similar to the first embodiment.

[0044] The spacer 5 may be attached to the lateral surface 11 of the mullion 1 at a position opposite to the adjustment portion 3. The spacer may also be attached to the inner surface 321 of the positioning portion 32. The spacer 5 is not limited to being provided at all three locations in the above example. For example, it may be provided at least one of the locking piece 23, the rib 25, and the reinforcing portion 29.

[0045] For example, by adjusting the thickness of the spacer 5 relative to the adjustable dimension of the locking piece 23 within the adjustment section 3, the width X dimension of the connected window unit 100A can be further adjusted in multiple steps. For example, if the width X dimension of the connected window unit 100B can be adjusted in 1.0 mm increments depending on the position of the locking piece 23 within the adjustment section 3, by setting the thickness of the spacer to 0.5 mm, the width X dimension can be further adjusted in multiple steps by attaching and detaching the spacer 5.

[0046] According to the connected window units 100, 100A, 100B, 100C and connected window mullion structures of the above embodiments, an adjustment part 3 is provided that protrudes from the lateral side surface 11 of the mullion 1. When the locking pieces 23 provided on the vertical frames 2A, 2B are inserted into the adjustment part 3, a gap S is created within the adjustment part 3. Therefore, by moving the mullion 1 in the width direction X, the position of the mullion 1 in the width direction X relative to the vertical frames 2A, 2B can be easily adjusted. The position of the mullion 1 in the width direction X relative to the vertical frames 2A, 2B can be adjusted by bringing one side of the locking piece 23 into contact with the lateral side surface 11 or the inner surface 321. The position in the width direction X can be changed by a predetermined length depending on whether the locking piece 23 is in contact with the inner surface 321 of the adjustment part 3 or with the lateral side surface 11. Therefore, positioning can be done with simple operation without performing millimeter-level positioning work at the construction site, improving work efficiency.

[0047] According to the above embodiment of the continuous window units 100, 100A, 100B, 100C and the continuous window mullion structure, the mullion 1 is provided with two adjustment parts 3, and the positions of the pair of vertical frames 2A and 2B in the width direction X can be positioned accordingly. As a result, the width direction X dimension of the continuous window unit 100 can be adjusted in multiple stages.

[0048] According to the connected window units 100, 100A, 100B, and 100C of the above embodiments, the length of the adjustment section 3 in the width direction X is greater than the thickness T23 of the locking piece 23 in the width direction X. Therefore, when the locking piece 23 is inserted into the adjustment section 3, a gap S is formed between the inner surface 321 and the lateral surface 11. Thus, the position of the locking piece 23 in the width direction X within the adjustment section 3 can be adjusted.

[0049] According to the connected window units 100, 100A, 100B, 100C and connected window mullion structures of the above embodiments, the adjustment part 3 is formed protruding from the lateral side surface 11 of the mullion 1, and the adjustment part 3 has an inner surface 321 which is a positioning surface that extends parallel to the lateral side surface 11, and a locking piece 23 is arranged between the lateral side surface 11 and the inner surface 321. The length of the lateral side surface 11 and the inner surface 321 in the width direction X is greater than the width direction X dimension of the locking piece 23, and a gap S is formed inside the adjustment part 3 when the locking piece 23 is positioned in the adjustment part 3. Therefore, the position of the locking piece 23 in the width direction X within the adjustment part 3 can be adjusted. The position of the mullion 1 in the width direction X relative to the vertical frames 2A, 2B is positioned by the locking piece 23 contacting the inner surface 321 or the lateral side surface 11. As a result, positioning can be done with simple operation without performing millimeter-level positioning work at the construction site, improving work efficiency.

[0050] According to the continuous window unit 100A and continuous window mullion structure of each embodiment described above, the end portion 34 of the adjustment portion 3 has an inclined surface 341, making it easier to insert the locking piece 23 into the adjustment portion 3 and improving workability. In particular, when the vertical frames 2A and 2B are attached from a position inclined relative to the mullion 1, the locking piece 23 is less likely to come into contact with the adjustment portion 3 and can be inserted smoothly.

[0051] According to the connected window units 100, 100A, 100B, 100C and connected window mullion structures of the above embodiments, the vertical frames 2A and 2B are provided with ribs 25 whose position in the width direction X coincides with the inner surface 321 of the adjustment part 3. Therefore, when attaching the vertical frames 2A and 2B close to the mullion 1, the positioning by the locking piece 23 can be guided by the ribs 25. When positioning or fixing the vertical frames 2A and 2B relative to the mullion 1, rattling of the vertical frames 2A and 2B can be suppressed, allowing for smooth assembly work.

[0052] According to the connected window unit 100C and connected window mullion structure of each embodiment described above, the width X dimension of the connected window unit 100 can be easily adjusted by removing the spacer 5. The width X dimension of the connected window unit 100A can be further adjusted in multiple stages by adjusting the thickness of the spacer 5 relative to the adjustable dimension of the locking piece 23 within the adjustment section 3.

[0053] In the embodiments described above, the adjustment portion 3 is shown to be formed protruding from the lateral side surface 11 in the width direction X. However, the position of the adjustment portion 3 is not limited to the lateral side surface 11 of the mullion 1. For example, the adjustment portion 3 may be provided on the outer surface 15 of the outer body 4b on the outdoor side O. Specifically, instead of the L-shaped cross-sectional adjustment portion 3 in the embodiments described above, a pair of positioning portions may be provided that protrude from the outer surface 15 towards the outdoor side O and extend parallel to each other to form a slit-shaped groove. The locking pieces of the vertical frames 2A and 2B are inserted into the groove, and one surface of the locking piece is brought into contact with the positioning portion to position the vertical frames 2A and 2B in the width direction X.

[0054] In the embodiments described above, examples of the adjustment section 3 having a substantially L-shaped horizontal cross-section were shown, but the shape of the adjustment section is not limited thereto. The adjustment section only needs to include a positioning section that protrudes from the side surface of the mullion 1 and extends along the indoor-outdoor direction Y. For example, the adjustment section may have a substantially L-shaped cross-section in the vertical direction Z.

[0055] In the above embodiment, an example was shown in which the gap S between the adjustment part 3 and the locking piece 23 was unified, but the invention is not limited to this example. For example, the dimensions of the gap S may be set to different dimensions for each adjustment part 3 of the mullion 1, and further fine adjustment may be made. For example, the dimensions L31 of each adjustment part 3 may be set so that the size of the gap S of one adjustment part 3 is 1.0 mm and the size of the gap S of the other adjustment part 3 is 1.5 mm. In this case, the range of fine adjustment of the width X dimension of the continuous window unit 100 is further widened.

[0056] The embodiments described above are illustrative and not limited to the scope of the above disclosure. The embodiments described above can be carried out in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the disclosure. These embodiments and their variations are included in the claims and their equivalents. [Explanation of Symbols]
