Description

  The present invention relates to a connecting structure of composite window frames in a continuous window sash formed by connecting a plurality of composite window frames with resin frames attached to the interior side of a metal frame in a horizontal direction through a vertical.

  Patent Document 1 discloses a continuous window sash formed by connecting a plurality of composite window frames provided with a resin frame on the indoor side of a metal frame in a horizontal direction through a vertical. In the connection structure of the composite window frame in this document, the resin frame has an angle portion protruding in an L shape on the indoor side along each side of the substantially square, and the vertical is between the adjacent vertical frames. And the interior of the room extending from the upper end of the upper frame to the lower end of the lower frame and the interior of the interior extending from the angle of the upper frame to the angle of the lower frame. A resin vertical cover is mounted on the side of the room. The vertical cover extends in the vertical direction between the angled portions of the vertical frames that are adjacent to each other, and the upper end surface and the lower end surface of the vertical cover are in positions where the upper frame and the lower frame of the adjacent composite window frame do not exist. There is a gap between the upper and lower ends of the vertical cover and the upper and lower frames, which causes the appearance to be deteriorated, in contact with the lower surface of the upper frame or the upper surface of the lower frame constituting the frame (hereinafter simply referred to as the frame). It is attached so as not to occur.

Accordingly, as shown in FIG. 12, the storage form of the angle portion of the upper frame and the angle portion of the lower frame is a recess (in this application ) for fitting the angle portion to the frame 8 (81, 82) . Is referred to as “shakuri”) (the same figure (a)) and there are two cases (the same figure (b)) when the shank 8a is formed. In either case, the same composite window frame can be attached without changing its dimensions. When there is no shackle, the angle portion 12 of the upper frame protrudes downward from the lower surface of the upper frame 81 by the thickness, and the angle portion 22 of the lower frame extends upward from the upper surface of the lower frame 82 by the thickness. Protruding. When there is a shackle, the angle portion 12 of the upper frame and the angle portion 22 of the lower frame are fitted to the shackle 8a of the upper frame 81 and the shackle 8a of the lower frame 82, respectively, and the lower surface of the angle portion 12 of the upper frame And the lower surface of the upper frame 81 are substantially on the same surface, and the upper surface of the angle portion 22 of the lower frame and the upper surface of the lower frame 82 are approximately on the same surface. In any case, the vertical cover 7 is attached so that the lower end thereof is in contact with the vertically opposed surface of the frame 8, so that the length of the vertical cover 7B when there is shackle is It is necessary to be at least above the length of the vertical cover 7 </ b> A when there is no shackle and shorter by a length equal to the sum of the thicknesses of the angle portions 12 and 22 of the lower frame.

Therefore, conventionally, a vertical cover 7A having a long dimension without shackle is manufactured, and when the storage form is with shackle at the construction site, the vertical cover 7A is placed on the upper and lower frames. The vertical cover 7B was made by cutting a length equal to the sum of the thicknesses of the angle portions.

  Therefore, the prior art has a problem that cutting may be required at the construction site. As in the case of the window sash, there is a trapezoidal window sash formed by connecting a trapezoidal composite window frame in which the upper frame is inclined in a horizontal direction through a vertical, similar to that described in Patent Document 1. In this case, however, the upper surface of the vertical cover is provided with an inclined upper surface that matches the inclination angle of the lower surface of the upper frame. Therefore, there has been a problem that it is not easy to perform processing so that an inclined upper surface having a predetermined angle is formed at the time of on-site cutting.

  The present invention has been made on the basis of the above circumstances, and the problem is that the vertical cover can be attached without the need to remove the vertical cover regardless of the presence or absence of the shackle. An object of the present invention is to provide a composite window frame connection structure that does not generate a gap that causes a decrease in appearance between the cover and the frame.

In order to solve the above-mentioned problems, the present invention connects a plurality of composite window frames (hereinafter simply referred to as window frames) with a resin frame attached to the interior side of a metal frame in a lateral direction through a vertical. A window sash is formed , and a frame is attached to the outer peripheral side of the angle portion extending in the indoor direction provided on the upper frame, the lower frame, and the vertical frames at both ends, and the resin frame is made of resin on each side of the indoor side. In the connecting structure of the composite window frame to which the vertical cover is attached, the vertical cover is provided between the angled portions of the adjacent vertical frames of the resin frame, and is provided between the upper and lower frame. The height ( H2 ) of the vertical cover is set shorter by a predetermined dimension ( h ) than the distance ( H1 ) between the opposing surfaces of the angle portions of the upper and lower frames of the resin frame, and the lower end of the vertical cover in part, the on the frame of the opposed surfaces of the upper and lower, match fitting the angle portion of the lower frame Surging in response of whether they are provided, characterized by comprising an adjusting member that adjust the length of the lateral upright cover (claim 1).
With the above configuration, when the angle portions of the upper and lower frames of the window frame are attached to the surface of the frame without shakiness, a predetermined dimension (h1) is provided between the lower end surface of the vertical cover and the upper surface of the angle portion of the lower frame. ), A gap equal to the sum of the thicknesses of the upper and lower angle portions (2h1) is generated. However, since an adjustment member is provided at the lower end of the vertical cover, it is interposed between the vertical cover and the upper surface of the lower frame. Then, the gap is closed by the compressed adjustment member. Accordingly, the upper end surface of the vertical cover abuts on the lower surface of the upper frame, and the gap between the lower end surface of the vertical cover and the upper surface of the lower frame is closed by the adjustment member.

According to the present invention, the adjustment member is detachable so as to be interposed between a hard synthetic resin cap attached to the lower end surface of the vertical cover and an upper surface of the cap between the lower end surface of the vertical cover. The predetermined size h is equal to the thickness h1 of the bottom plate of the cap, and the maximum compression amount h2 of the cushion is the thickness h3 of the angle portion of the upper frame of the composite window frame. Equality (claim 2).
With the above configuration, the adjustment member is configured by placing an elastic cushion material on the hard cap. It can be easily manufactured with two parts of a hard cap and an elastic cushion material. Since the adjustment member is divided into a hard cap and an elastic cushion material, the cap part is securely fixed to the vertical cover, and the cushion material has a small gap between the vertical cover and the upper surface of the lower frame. Can respond flexibly.

Further, the present invention is characterized in that the cushion material is composed of two layers of an upper layer having a low compression rate and a lower layer having a high compression rate (Claim 3).
With this configuration, the compressive force applied from the vertical cover to the upper layer of the cushion material is evenly distributed to the lower layer, so that the cushion material is prevented from being partially compressed more than necessary, and is The repulsive force works effectively. Accordingly, the upper end portion of the vertical cover is in close contact with the lower surface of the upper frame.

Further, in the present invention, when the angle portions of the upper frame and the lower frame of the window frame are attached to the surface of the frame without shaki, the adjustment member is used by placing a cushion material on the cap. When the angle part of the lower frame is attached to the surface of the frame having the shackle, the adjustment member is used with the cushion material removed, and in either case, the upper end of the vertical cover is substantially flush with the lower surface of the upper frame. And the cap seals the gap between the lower end of the vertical cover and the upper surface of the lower frame (claim 4).
With the above configuration, when the angled portions of the upper and lower frames of the window frame are attached to the surface of the frame without shackle, when the vertical cover is used without changing the length, the lower end surface of the vertical cover and the lower frame Since the cap and the cushion material are interposed in the gap formed between the upper surface and the gap, the gap is easily and securely closed, and the angle portions of the upper and lower frames of the window frame are attached to the surface of the frame having shackles. Since the cushioning material is removed, the space between the lower end surface of the vertical cover and the upper surface of the lower picture frame can be shielded with a cap as thin as possible.

The cap protrudes from the bottom plate covering the lower end surface of the vertical cover, a protrusion protruding from the upper surface of the vertical plate, fitted and fixed to the vertical cover from its lower end, and the indoor end of the bottom plate. An upright portion covering the interior surface of the lower end portion of the vertical cover, a first convex portion protruding on the lower surface of the bottom plate with a height equal to the thickness of the angle portion of the lower frame, and a lower portion of the upright portion And a second convex portion having a break line at the base, and the angle portions of the upper and lower frames of the window frame are attached to the surface of the frame having shackles. In this case, it is desirable that the second convex portion has a structure that can be cut off at the breaking line.
In the above configuration, the bottom plate and the protrusion allow the cap to be securely and stably attached to the vertical cover, the upright portion securely fixes the cap to the vertical cover, and the first convex portion is configured to fix the cap to the lower frame. Hold it stably on the top surface. The second convex portion can be broken along the breaking line.

Further, according to the present invention, the distance between the opposing surfaces of the angle portions of the upper and lower frames is H1, the distance between the lower surface of the upper frame and the upper surface of the lower frame is H3, the thickness of the bottom plate of the cap is h1, and the maximum compression amount of the cushion material Is h2, and the thickness of the angle portion of the lower frame is h3, the length H2 of the vertical cover is the expression H3 = H2 + (h + h3) = H2 + (h1 + h2 + h3) when there is no shackle on the frame, In this case, the expression H3 = H1 = H2-h1 is established (Claim 6).

  The continuous window sash includes a trapezoidal window sash formed by sequentially connecting trapezoidal window frames of different sizes in the horizontal direction. According to the present invention, in such a trapezoidal window sash, the upper end surface of the vertical cover is formed in an inclined shape that is substantially continuous with the lower surface of the angle portion of the upper frame.

  According to the first aspect of the present invention, the height (H2) of the vertical cover is set shorter than the distance (H1) between the opposing surfaces of the angle portions of the upper and lower frames of the window frame by a predetermined dimension (h). The vertical cover has an adjustment member that has a function of adjusting the length of the vertical cover by changing the thickness of the vertical cover and the amount of compression according to the presence or absence of the shank of the frame. When the angle part is attached to the surface of the frame without shackles, a gap of a predetermined dimension (h) generated between the lower end surface of the vertical cover and the upper surface of the angle part of the lower frame is the vertical cover and the lower frame. And is closed by a compressed adjusting member. The upper end surface of the vertical cover is in contact with the lower surface of the upper frame. Therefore, the vertical cover can be used without the need for cutting regardless of the presence or absence of shackle. Therefore, construction on site becomes easy.

  According to the invention of claim 2, the adjusting member is interposed between a hard synthetic resin cap mounted on the lower end surface of the vertical cover and an upper surface of the cap between the lower end surface of the vertical cover. The predetermined dimension h is equal to the thickness h1 of the bottom plate of the cap, and the maximum compression amount h2 of the cushion is the thickness of the angle portion of the upper frame of the composite window frame. Since it is set equal to h3, the adjusting member can be easily manufactured with two parts of a hard cap and an elastic cushion material placed on the hard cap, and is divided into a hard cap and an elastic cushion material. Therefore, it is possible to securely fix the vertical cover and to flexibly cope with the gap formed between the vertical cover and the upper surface of the lower frame by the cushion material.

According to the invention of claim 3, since the cushion material is composed of the upper layer having a small compressibility and the lower layer having a large compressibility, the compressive force applied from the vertical cover to the upper layer of the cushion material is evenly applied to the lower layer. Since it is dispersed, the cushion material is prevented from being partially compressed more than necessary, and the upward repulsive force acts effectively on the vertical cover, so that the upper end of the vertical cover is It is in close contact with the lower surface.

  According to invention of Claim 4, when the angle part of the upper frame of a window frame and a lower frame is attached to the surface of a frame without a shackle, a cap and a cushion between the lower end surface of a vertical cover and the upper surface of a lower frame Since the cushion material is removed when the angled parts of the upper and lower frames of the window frame are attached to the surface of the frame with shackles, even if a vertical cover with the same length is used, Regardless of the presence or absence, an unnecessary gap does not occur between the lower end surface of the vertical cover and the upper surface of the lower frame, and a cap that is as thin as possible can be used.

  According to the fifth aspect of the present invention, the cap is reliably and easily attached to the vertical cover by the bottom plate and the protrusion, and is securely fixed to the vertical cover by the standing portion, and the lower end of the vertical cover Generation of a gap between the lower frame is prevented, and the cap is held in a stable state on the upper surface of the lower frame by the first convex portion. In addition, the second convex part can be cut off at the breaking line when the angle part of the upper frame and lower frame of the window frame is attached to the surface of the frame having the shackle, so that the cap is stably fitted and fixed to the shackle. Is done.

According to the invention of claim 6, the distance between the opposing surfaces of the angles of the upper and lower frames is H1, the distance between the lower surface of the upper frame and the upper surface of the lower frame is H3, the thickness of the bottom plate of the cap is h1, and the maximum cushion material When the amount of compression is h2, and the thickness of the angle portion of the lower frame is h3, the length H2 of the vertical cover is expressed by the formula H3 = H2 + (h1 + h2 + h3) when there is no shackle on the frame, and when the frame has shackle. Since the expression H3 = H1 = H2-h1 is established, the length H2 of the vertical cover is set to the thickness h1 of the bottom plate of the cap, the maximum compression amount h2 of the cushion material, and the thickness h32 of the angle portion of the lower frame. It can be set easily and reliably corresponding to the above.

  According to the invention of claim 7, in the trapezoidal window sash formed by sequentially connecting the trapezoidal window frames of different sizes in the horizontal direction, the upper end surface of the vertical cover is substantially continuous with the lower surface of the angle portion of the upper frame. When the angled parts of the upper and lower frames are attached to the surface of the frame without shackles, the distance between the lower end of the vertical cover and the upper surface of the lower frame is Some variation occurs depending on the inclination angle of the lower surface of the angle portion, but the variation is absorbed within the range of compressibility of the cushion material.

  As shown in FIG. 1, the window frame connecting structure of the trapezoidal window sash in the illustrated embodiment is configured such that a plurality of window frames 1 are connected in a horizontal direction via a stand 2.

  Each window frame 1 has an upper frame 10 and a lower frame 20 in which the resin frame 4 is coupled to the interior side of the metal frame 3 and left and right vertical frames 30 and 30 in a trapezoidal shape so that the upper frame 10 is inclined. Is. The left and right vertical frames 30 and 30 have different lengths, but the lower frame 20 is arranged substantially horizontally with the lower ends thereof arranged at the same height. On the other hand, the vertical frame 30 is erected, and the upper ends thereof have different heights. Therefore, the upper frame 10 is disposed in an inclined shape, and the upper end portion of the vertical frame 30 and the vertical frames 30 and 30 of the upper frame 10 are arranged. Both end portions that are abutted against are cut obliquely with respect to the material axis so as to match the inclination angle of the upper frame. Thus, the upper frame 10 is disposed so as to be suspended between the upper ends of the vertical frames 30 and 30 having different heights, thereby forming a trapezoidal window frame 1.

  The resin frames 4 of the upper and lower frames 10 and 20 and the left and right vertical frames 30 and 30 have angle portions 12, 22, and 32 protruding in an L shape on the indoor side, as in the known composite window frame. That is, the resin upper frame 11 has the upper angle portion 12 over substantially the entire length, the resin lower frame 21 has the lower angle portion 22 over the substantially entire length, and the resin vertical frame 31 has the almost entire length. Vertical angle portions 32 are respectively formed. The upper angle portion 12, the lower angle portion 22, and the left and right vertical angle portions 32, 32 are continuous along substantially four sides of the trapezoidal resin frame.

  In the figure, 5 is a glass plate housed in each window frame 1, and 6 is a pressing edge provided over the entire length in the longitudinal direction with respect to the resin 3 of the upper frame 10, the lower frame 20 and the vertical frame 30. The glass plate 5 is sandwiched and fixed between the convex edges 13, 23, 33 formed on the metal frame 2 of the upper frame 10, the lower frame 20, and the vertical frame 30.

  The trapezoidal window sash S shown in FIG. 1 connects three window frames 1 whose heights are gradually lowered via a stand 2. As shown in FIGS. 2, 4, and 5, the vertical 2 is provided between the vertical frames 30 that are adjacent to each other on the left and right, and connects and fixes the vertical frames 30. The vertical 2 is made of a metal member having a substantially T-shaped cross section, and integrally includes an outdoor portion 41 corresponding to a vertical portion of the T shape and an indoor portion 42 corresponding to a horizontal portion of the T shape. The outdoor part 41 has a length longer than the distance between the upper angle part 12 and the lower angle part 22 of the window frame 1, but the upper part and the lower part of the indoor part 42 are cut off at the upper angle part. 12 has a length slightly shorter than the distance between the lower angle portion 22 and the lower angle portion 22. And the lower end 41a of the outdoor part 41 is cut | disconnected horizontally according to the lower end of the lower frame 20, and the upper end 41b is cut | disconnected diagonally according to the upper frame 10 inclined. Moreover, both the upper end and lower end of the indoor part 42 are cut | disconnected horizontally.

  The outdoor exterior 41 of the vertical 2 holds the tight material 43 over substantially the entire length in the longitudinal direction and connects the tight material 40 in close contact with the vertical frame 30 to secure the water tightness of the sash. Yes. Further, the vertical 2 is a bent projecting edge provided with engaging portions 44 and 45 formed at the distal end portion and the intermediate portion of the outdoor portion 41 at the outdoor end portion and the intermediate portion of the metal frame of the vertical frame 30, respectively. 34, 35, and both sides of the indoor portion 42 are brought into contact with the bent protrusion 36 provided at the indoor side end of the metal frame of the vertical frame 30, and screwed at several points in the longitudinal direction from the indoor portion 42. By doing so, the vertical frame 30 is connected and fixed.

  When adjacent vertical frames 30, 30 are connected by the vertical 2, a recess is formed by the indoor portion 42 of the vertical 2 and the vertical angle portions 32, 32 protruding to the indoor side of each vertical frame 30. And the standing cover 7 is mounted | worn and fixed so that the opening surface of this recessed part may be covered.

The vertical cover 7 is made of a resin hollow shape having a hollow portion 71 and covers the indoor side surface of the metal vertical 2 for the purpose of improving the heat insulation and design of the sash. The vertical cover 7 is fixed by screwing from the vertical angle portion 32. In this case, since the metal part of the window frame does not intervene, the heat insulating property of the sash is prevented from being lowered. The vertical cover 7 also covers the indoor side surface of the vertical angle portion 32 , and is configured to substantially cover the connecting portion of the window frame 1 viewed from the indoor side. Further, since the vertical cover 7 is formed to have the same size as the vertical direction of the vertical angle portion 32 , the vertical cover 7 is attached to the vertical 2, so that the window frames 1 and 1 can be viewed from the indoor side. Can be provided with an integrally continuous appearance.

Further, when the frame 8 is attached to the trapezoidal window sash S as shown in FIG. 9, the vertical cover 7 includes the upper angle portion 12 of one window frame and the other of the window frames 30, 30 adjacent to the left and right. and extending over until the gap between the lower angle portion 22 of the lower angle portion 22 and the other of the window frame of one window frame from the gap between the angle portion 12 on the window frame. For this reason, the lower end 73 of the vertical cover 7 is cut horizontally so as to fit the upper surface of the lower frame 82. On the other hand, the upper end 72 of the vertical cover 7 is cut obliquely so as to fit the lower surface of the inclined upper frame 81. By forming the vertical cover 7 in this way, it is possible to ensure an external appearance of the continuous window sash after the vertical cover is mounted. As shown in FIGS. 1 and 10, the upper surface of the vertical cover 7 is disposed so as to be substantially continuous with the upper surface of the inclined upper angle portion 12.

As described above, the vertical frames 30 and 30 are fixed to the vertical 2 in the indoor portion 42 of the vertical 2. Here, the indoor portion 42 is disposed so as to be lower than the surface connecting the lower surfaces of the upper angle portions 12 and 12 of the window frame 1 to which the upper ends thereof are connected. Since the above-described vertical cover 7 is provided on the indoor side of the indoor portion 42 and the indoor portion 42 is not directly exposed to the indoor side, the upper end of the vertical indoor portion 42 is formed as shown in the present embodiment. It is not always necessary to cut obliquely in accordance with the inclined upper frame 10.

As described above, a plurality of window frames 1 are connected laterally through the vertical 2 and the window sash S with the vertical cover 7 attached to the vertical interior surface is attached to the building, and then each angle is set. The frame 8 is attached to the outer peripheral side of the parts 12, 22, 32. The frame 8 is formed by continuously connecting an upper frame 81, a lower frame 82, and left and right vertical frame 83 into a rectangle (a trapezoid in the case of a trapezoidal window sash). As shown in FIG. 9, the window 8 has the upper angle portion 12 and the lower angle portion 22 accommodated in the frame 8 as shown in FIG. In the former case, the lower angle portion 12 is attached in such a manner that the lower surface protrudes from the lower surface of the upper frame 81 and the upper surface of the lower angle portion 22 protrudes from the upper surface of the lower frame 82 . In the latter case, the upper angle portion 12 and the lower angle portion 22 are fitted to shackles formed on the upper frame 81 and the lower frame 82 , respectively, so that the lower surface of the upper angle portion 12 and the lower surface of the upper frame 81 are The upper surface of the lower angle portion 22 and the upper surface of the lower frame 82 are attached in such a manner that they exist on the same plane.

Therefore, the distance between the opposing surfaces of the upper and lower frame in the former storage form is larger than that in the latter storage form by a distance equal to the sum of the thickness of the upper angle part and the thickness of the lower angle part. In addition, in order to improve the appearance of the continuous window sash, the vertical cover 7 is required to have its lower end portion abutted against the opposing surfaces of the upper and lower frame so that no gap is generated therebetween.
Conventionally, in order to respond to such a demand, a vertical cover having a different length depending on a storage form has been used, so that there has been a problem as described above.

  In the present invention, in order to solve the problem, first, as shown in FIG. 11, the height (length) H <b> 2 of the vertical cover 7 is higher than the distance H <b> 1 between the opposing surfaces of the lower angle portions 12 and 22. It was set shorter by a predetermined dimension h. And as shown in FIG. 7, the adjustment member 9 was provided in the lower end part of the vertical cover 7. As shown in FIG. The adjustment member 9 has a function of adjusting the length of the vertical cover 7 by changing the thickness and compression amount of the frame 8 depending on whether or not the frame 8 is shaved.

  The adjusting member 9 having the function of adjusting the length of the vertical cover 7 by changing its own thickness and compression amount is, as shown in FIG. 7 and FIG. 8, an example of a hard composite mounted on the lower end surface of the vertical cover. It consists of a resin cap 9a and a compressible elastic cushion material 9b that is detachably mounted on the upper surface of the cap so as to be interposed between the lower end surface of the vertical cover.

  The cap 9a includes a bottom plate 91 that covers the lower end surface of the vertical cover 7, a protrusion 92 that protrudes from the upper surface of the vertical plate, and is fitted and fixed to the vertical cover from the lower end thereof. An upright portion 93 that stands up from the bottom and covers the interior surface of the lower end portion of the vertical cover, and a first convex portion 94 that protrudes from the bottom surface of the bottom plate 91 with a height equal to the thickness of the lower angle portion 22 of the window frame, The second projection 96 has a second projection 96 that protrudes to a position equal to the lower surface of the first projection 94 below the standing portion 93 and has a break line 95 at the base. The second convex portion 96 is cut off at the breaking line 95 when the angle portions 12 and 22 of the upper and lower frames of the composite window frame are attached to the surface of the frame 8 having the shackle.

  On the other hand, as illustrated in FIG. 8D, the cushion material 9b is composed of two layers of an upper layer 97 having a low compression rate and a lower layer 98 having a high compression rate. The cushion material is formed with a hole 99 and a small hole 910 penetrating in the thickness direction at the center and both sides thereof. The cap material 9 a is also provided with small projections 911 corresponding to the small holes 910 on both sides of the projection 92. Therefore, by placing the cushion material 9b on the cap 9a, and fitting the protrusion 910 into the hole 99 and the small protrusion 911 into the small hole 910, the cushion material 9b can be attached to and detached from the upper surface of the cap 9a. It is fixed.

  When the adjustment member 9 pushes the protrusion 92 of the cap 9a into the hollow portion 71 from the lower end portion of the vertical cover 7 with the cushion material 9b attached to the cap 9a or with the cushion material 9b removed, The bottom cover is fixed in a state in which the lower end edge of the vertical cover is held against the upper surface of the bottom plate 91 of the cap. In that case, the standing portion 93 of the cap 9a covers the interior surface of the vertical cover, and its lateral end is bent outward. This bent portion also covers the lateral end surface of the indoor wall of the vertical cover. Thereby, rattling of the mounted adjustment member is prevented.

  The predetermined dimension h in which the length H2 of the vertical cover 7 is upper and shorter than the distance H1 between the opposing surfaces of the lower angle portions 12 and 22 is equal to the thickness h1 of the bottom plate 91 of the cap 9a. The maximum compression amount h2 of the cushion is at least equal to the thickness h3 of the upper angle portion 12. Further, the heights of the first convex portion 94 and the second convex portion 95 of the cap 9a are at least equal to the thickness h3 of the lower angle portion 22.

The mode of use and action and effect of the adjustment member 9 for the vertical cover 7 differ depending on how the adjusting window 9 is fitted to the frame of the continuous window sash. This will be described with reference to FIG.
First, as shown in FIG. 5A, when attaching the frame 8A without shackle, the adjustment member 9 in which the cushion material 9b is placed on the cap 9a is attached to the vertical cover 7.
In this case, the second convex portion 96 of the cap remains attached. Therefore, when a shackleless frame is attached to the continuous window sash fitted with the vertical cover 7 to which the adjustment member is attached, the lower end surface of the adjustment member at the lower end from the upper end surface of the vertical cover 7, that is, The distances to the lower end surfaces of the first and second convex portions 95 and 96 are substantially equal to the distance H3 between the opposing surfaces of the upper and lower picture frames 81 and 82. Accordingly, no gap is generated between the upper end surface of the vertical cover 7 and the lower surface of the upper frame 81, and the upright portion 93 of the cap 9 a and the lower frame 82 are provided between the lower end surface of the vertical cover 7 and the lower frame 82. It is shielded by the second convex part 96.

  Next, as shown in FIG. 5B, when attaching the frame 8B with shackle, the adjustment member 9 obtained by removing the cushion material 9b from the cap 9a is attached to the vertical cover 7. In this case, the second convex portion 96 of the cap is cut off from the cutting line, and only the first convex portion 94 of the cap is stably fitted to the shackle of the lower frame 82, and the first convex portion 94 of the bottom plate 91 is The surface after the two convex portions are removed is brought into contact with the upper surface of the lower frame 82. The upper end surface of the vertical cover 7 is in contact with the lower surface of the upper frame 81 and is fixed in a state where the bottom surface of the bottom plate 91 of the cap of the adjustment member is in contact with the upper surface of the lower frame. Therefore, even in this stowed configuration, no gap is generated between the upper end surface of the vertical cover 7 and the lower surface of the upper frame 81, and a cap is not provided between the lower end surface of the vertical cover 7 and the lower frame 82. It is shielded by the standing part 93 of 9a.

  As described above, according to the present embodiment, in the case of a frame without shackle, the adjustment member 9 formed by coupling the cushion material 9b to the cap 9a is attached to the vertical cover. By attaching only the cap 9a from which the cushion material has been removed to the vertical cover, the vertical cover having the same dimensions can be used regardless of the presence or absence of shackle. Therefore, it is not necessary to cut the vertical cover at the construction site, so that the construction cost is reduced. In particular, in the case of a trapezoidal window sash, when performing a vertical cutting process at the construction site, the cutting angle must be matched with the inclination angle of the upper angle, but this difficulty is eliminated.

  In the above embodiment, the case of the trapezoidal window sash has been described. However, the present invention can be similarly applied to a window sash formed by connecting rectangular composite window frames whose upper frames are horizontal. Further, in the present embodiment, the sash in which the three window frames 1 are connected in the lateral direction is shown. However, the number of connections may be any number, and the vertical 2 and the adjusting member may be adapted to each connection portion. The attached side cover 7 may be used.
