This shows the upper frame and the watertight packing 70 of the window frame 60. Although illustration of the lower frame is omitted, the watertight packing 70 fixed to the lower frame of the window frame 60 has a drain hole for draining water that has entered between the watertight packing 70 and the window frame 60. Is provided.

Next, details of the cross-sectional shape of the watertight packing 70 will be described in detail with reference to FIG. Here, FIG.
The upper part of the paper surface is also the upper part of the actual watertight packing 70. In addition, on the lower frame side of the window frame 60, the upper side of the paper in FIG. 3 is the lower side in the actual watertight packing 70. The watertight packing 70 according to the present embodiment
A base portion 70A formed of a hard material, which is a portion fixed to the outer peripheral surface of the window frame 60, and a portion provided on the sash frame 40 side of the base portion 70A and in contact with the inner peripheral surface of the sash frame 40. It is integrally formed with a watertight part 70B formed of a certain flexible soft material.

The base portion 70A has a strip-shaped fixing portion 71 which is a portion fixed to the outer peripheral surface of the window frame 60, and a central portion of a cut surface of the fixing portion 71 is projected toward the sash frame 40 side. A ridge curved portion 77 formed by being curved in an inverted U-shape;
A substantially T-shaped central ridge 72 erected from the ridge curved portion 77 to the sash frame 40 side, and two ends of the cut surface of the fixed portion 71 slightly shifted toward the central ridge 72 side. Sash frame 4
A first side standing ridge 73 and a second side standing ridge 74 which are formed by bending the erected members approximately 90 degrees toward the opposite center ridge 72 side. Are formed integrally.

The first side uprights 73 and the second side uprights 7
4 are respectively erected and bent as described above between the fixing portion 71 and the bent portions of the first side erected member 73 and the second side erected member 74. This is because an appropriate gap is formed in the groove, and this gap is used as the window frame engaging groove 79. Therefore, the window frame engaging groove portion 79 is formed on the side surface of the two first side standing ridges 73 and the second side standing ridge 74 and on the side opposite to the center standing ridge 72. . More specifically, the window frame engaging groove 79 is used as follows.

That is, on the outer peripheral surface of the window frame 60, a projecting strip 61A slightly protruding from the both ends in the thickness direction of the window frame 60 toward the sash frame 40, and a front edge of the projecting strip 61A facing each other. Is provided, and when the fixing portion 71 is brought into close contact with the outer peripheral surface of the window frame 60,
The window frame engaging groove 79 is formed so as to be fitted to the locking ridge 61B of the window frame 60.

The sash frame 40 side of the ridge curved portion 77 has a concave portion 71A having a semicircular cross section so as to avoid the head of the fastening member 62 fastened to the outer peripheral surface of the window frame 60. The semi-circular space formed on the side opposite to the sash frame 40 of the ridge curved portion 77 formed and curved in an inverted U-shape is used. The non-curved portion of the fixing portion 71 on the side opposite to the sash frame 40 except for the concave portion 71 </ b> A is pressed against the outer peripheral surface of the window frame 60 when the fixing portion 71 is fixed to the window frame 60. It will be.

Next, the watertight portion 70B will be described. The watertight portion 70B is formed by branching into a T-shape and forming both ends of the upper portion of the central standing member 72 and the front end of the first side standing member 73 and the second side standing member 74 opposite the central standing member 72. And the sash frame 4
The two curved portions 75 having a substantially inverted U-shaped cross section that are in contact with the inner peripheral surface of 0 are connected in a bimodal shape, and are formed integrally with the base portion 70A in a state where the bimodal interior is hollow. It is. This hollow portion, that is, the base portion 70A
And the inner portions of the two curved portions 75 are respectively connected to the hollow portions 7.
5A. In addition, the part between the two curved parts 75 formed by being connected in two ridges is referred to as a valley part 71B for convenience of the following description.

On the side of the hollow portion 75A of the two curved portions 75, an inner groove portion 78 is provided near the center standing line 72, and an outer groove portion 76 is provided near the opposite center standing line 72. These grooves have a substantially semicircular cross section. The height of the watertight packing 70 thus formed is
Is higher than the distance from the outer peripheral surface to the inner surface of the sash frame 40. Therefore, when the window frame 60 is closed with respect to the sash frame 40, the watertight packing 70 is compressed between the sash frame 40 and the window frame 60.

The watertight packing 70 formed as described above
The base portion 70A is formed by integrally molding hard rubber and has water repellency. On the other hand, the watertight part 70B
It is made of soft rubber and has flexibility and water repellency. More specifically, both soft rubber and hard rubber use EPDM, which is ethylene-propylene rubber. The EPDM has a foaming property to change its hardness. That is, EP
DM is used as a soft rubber when the foaming amount is increased, and as a hard rubber when the foaming amount is reduced.

Next, a procedure for attaching the watertight packing 70 formed as described above to the window frame 60 will be described. First,
The watertight packing 70 is bent such that the concave portion 71A of the watertight packing 70 is narrowed. Then, the two window frame engaging grooves 79 approach each other. In this state, the watertight packing 70 is placed on the outer peripheral surface of the window frame 60, and the folded force is released. Then, the window frame engaging groove 79 of the watertight packing 70 that has returned to its original state by the elastic force fits into the locking ridge 61B of the window frame 60, and the fixing of the watertight packing 70 to the window frame 60 is completed. Become.

Next, a case where the window frame 60 is opened to the sash frame 40 and the window frame 60 is closed will be described with reference to FIG. Hereinafter, it is assumed that when the window frame 60 is closed, the right curved portion 75 of the watertight packing 70 comes into contact with the sash frame 40, and the left curved portion 75 in FIG. It is assumed that contact with the sash frame 40 starts toward the near side.

When the window frame 60 starts to be closed, the watertight packing 70 close to the rotation support shaft 60A of the window frame 60, and the vicinity of the outer groove portion 76 on the outer surface of the right-side curved portion 75 formed in a double mountain shape, First, the contact point starts to contact the inner surface of the sash frame 40. The curved portion 75 that has begun to contact the inner surface of the sash frame 40 is deformed inward so as to narrow the hollow portion 75A around the contact point. At the time of the deformation, the bending portion 75 is made of soft rubber, and the bending portion 75 is provided with not only the outer groove portion 76 but also the inner groove portion 78, so that the deformation near those grooves is particularly large. Become. Then, the right curved portion 75 is deformed so as to be biased toward the valley portion 71B. Subsequently, in FIG. 3, the right curved portion 75 is the sash frame 4
0, and the left curved portion 75 starts to contact the sash frame 40. The contact point at this time is near the inner groove 78 on the outer surface of the left curved portion 75. At the time of the deformation, the deformation near the outer groove 76 and the inner groove 78 becomes particularly large. And the left curved portion 75
Will be deformed away from the valley 71B.

Next, a case where the window frame 60 is closed with respect to the sash frame 40 and the window frame 60 is opened will be described. Note that the opening direction of the window frame 60 may be any direction since the sash window on which the watertight packing 70 of the present embodiment is applied can be opened both inside and outside the room. Assuming the cross section of the watertight packing 70 when opening is started, the window frame 60
Is deformed so as to be offset toward the valley 71B, and the other curved portion 75 is deformed so as to be offset toward the anti-valley 71B. As described above, regardless of whether the window frame 60 is closed or opened with respect to the sash frame 40, the watertight packing 70 is resiliently formed by the elastic force at the time of deformation of the curved portion 75 of the watertight portion 70B. Since it is pressed against the frame 40, watertightness is ensured.

The subsequent operation is the reverse operation of the above-described closing operation, and therefore the description is omitted. According to the watertight packing formed as described above, the watertight part 70B
By forming the two curved portions 75 in the shape of two peaks, even when the curved portion 75 which is one of the two peaks is improperly deformed by pressing when the window frame 60 is opened and closed, the other curved portions 75 are formed. The curved portion 75, which is the other peak, is adapted to the inner peripheral surface of the sash frame 40 by appropriate press-contact deformation to ensure watertightness. In this case, since the two curved portions 75 of the watertight portion 70B are formed of soft rubber, when the window frame 60 is opened and closed, the watertight portion 70B is appropriately pressed and deformed against the inner peripheral surface of the sash frame 40 to be watertight. Can be secured.

Further, a soundproofing effect can be ensured. That is, by using the watertight packing 70 according to the present embodiment, the normal packing material has a grade of about 20. However, the watertight packing 70 of the present embodiment has a grade of 35, which is lower than the normal packing material in terms of soundproofing effect. Can also be improved. Further, the watertight portion 70B is formed in a double mountain shape by two curved portions 75 having a substantially inverted U-shaped cross section, and is formed integrally with the base portion 70A in a state where the inside of the double mountain shape is hollow. When opening and closing the window frame 60,
When the OB contacts the inner peripheral surface of the sash frame 40, appropriate deformation can be maintained.

Further, a portion between the two peaks of the curved portion 75 formed in a double peak shape is formed as a valley portion 71B, so that when opening and closing the window frame 60, the watertight packing 70 is formed.
Since water adhering to the room can be captured, water can be prevented from entering the room. The inner groove portion 78 and the outer groove portion 76 are provided on the hollow portion 75A side of the two curved portions 75, respectively, so that the sash frame 40 comes into contact with the curved portion 75, or When the opening 75 is opened, the curved portion 75 is easily deformed. Therefore, opening and closing of the window frame 60 with respect to the sash frame 40 can be performed smoothly.

On the other hand, since the fixing portion 71 is formed of hard rubber, the fixing to the window frame 60 is strengthened.
The center standing line 72, the first side standing line 73, and the second side standing line 74 formed of the same hard rubber can be appropriately supported. In addition, since the center standing ridge 72, the first side standing ridge 73, and the second side standing ridge 74 are formed of hard rubber, the watertight portion 70B formed of soft rubber is appropriately supported, and ,
Improper deformation of the watertight part 70B can be prevented.

The sash frame 40 side of the ridge curved portion 77 is formed as a concave portion 71A that can avoid the head of the fastening member fastened to the outer peripheral surface of the window frame 60. The base portion 70A of the watertight packing 70 can be fixed to the window frame 60 without being affected by the fastening member fastened to the outer peripheral surface. Further, a window frame engaging groove 79 which can be fitted to the locking ridge 61B is formed on the side surface of the first side standing ridge 73 and the second side standing ridge 74 on the side opposite to the center standing ridge 72. This facilitates fixing the fixing portion 71 to the outer peripheral surface of the window frame 60.

The recess 71A, the inner groove 78, and the outer groove 7
6 has a substantially semicircular cross section, so that it is possible to avoid the concentration of bending stress at a specific location, and it is difficult to tear even when subjected to repeated deformation. Next, the long fastening portion cross section 81 will be described with reference to FIG. The long fastening section 81 is a section passing through the fastening member 69 in the long packing 80A as described above. The cross-sectional shape is almost the same as the typical cross-section described with reference to FIG. That is, a base portion 81A formed of a hard material, which is a portion fixed to the outer peripheral surface of the window frame 60, is provided on the sash frame 40 side of the base portion 81A, and is in contact with the inner peripheral surface of the sash frame 40. It is formed integrally with a watertight portion 81B formed of a flexible soft material as a portion. Base part 8
1A is provided with a centering hole 81C for molding. In addition, the detailed description, such as the fact that it has a two-ridged hollow watertight portion 81B, is omitted because it is duplicated.

Subsequently, based on FIG.
Will be described. The corner fastening section cross section 82 is a section passing through the fastening member 69 in the square packing 80B, and both the base section 82A corresponding to the base section 70A in FIG. 7 and the water tight section 82B corresponding to the water tight section 70B in FIG. It is formed with. Further, unlike the base portion 70A in FIG. 7, the base 82A does not have the concave portion 71A for the fastening member 69, and conversely has a fastening portion cutout portion 82C that is not present in the base portion 70A in FIG. . But,
The cross-sectional shape of the other portions is substantially the same as that shown in FIG. 7 and has a hollow watertight portion 82B having a double mountain shape.

Subsequently, referring to FIG.
Will be described. The support shaft section 83 is a cross section passing through the rotary support shaft 60A in the square packing 80B. Both the base section 83A corresponding to the base section 70A in FIG. 7 and the water-tight section 83B corresponding to the water-tight section 70B in FIG. The point formed of rubber is the same as the cross section 82 of the corner fastening portion. The point different from the corner fastening section cross-section 82 is that two hollow ridges formed by the watertight part 83B are located apart from each other, and a through hole 83C corresponding to the rotation support shaft 60A of the window frame 60 is provided between the two ridges.
Is provided.

Subsequently, the corner cross section 84 will be described with reference to FIG.
Will be described. The corner cross section 84 is a cross section at a position closer to the corner than the rotation support shaft 60A in the corner packing 80B. The base portion 84A corresponding to the base portion 70A in FIG. 7 and the water-tight portion 84B corresponding to the water-tight portion 70B in FIG. 7 are both formed of hard rubber, and the two hollow portions formed by the water-tight portion 84B. Are similar to the support shaft section 83. The difference from the support shaft section 83 is that the through hole 83C provided in the support shaft section 83 is continuously provided without being provided between the two peaks of the watertight portion 84B. The continuous portion between the two peaks is slightly dented toward the window frame 60.

Next, the angular section 85 will be described with reference to FIG. The corner cross section 85 is a cross section of a corner of the corner packing 80B. The base portion 85A corresponding to the base portion 70A in FIG. 7 and the water-tight portion 85B corresponding to the water-tight portion 70B in FIG. 7 are both formed of hard rubber, and the two hollow portions formed by the water-tight portion 85B. The point that is located apart from each other and is continuous between them,
This is the same as the corner cross section 84. The difference from the corner cross-section 84 is that the dent of the continuous portion between the two peaks toward the window frame 60 is larger than the corner cross-section 84 and the corner of the sash frame 40 from the top position of the two peaks of the watertight portion 85B. This is a point having a protruding portion 85C protruding toward the portion.

Next, the packing sectional structure 80 as described above is used.
