  However, in the sash of Patent Document 1, when the retrofitting bead is pushed between the panel panel-finding surface facing part of the frame and the panel and engaged with the panel panel-finding surface opposing part, the entire retrofitting bead is made of a soft resin. Since the outer peripheral side engaging portion remains elastically deformed, the outer peripheral side engaging portion may not be able to engage with the outer peripheral side engaged portion of the panel facing surface of the frame. The retrofitted bead attached to the upper part (upper frame) of the frame without being engaged may fall by its own weight due to deterioration over time.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a sash that can prevent the fall of a retrofitted bead even when it has deteriorated over time.

The invention according to claim 1 includes a frame, a panel, and a retrofitting bead, and the frame has a panel finding surface facing portion that faces the finding surface of the panel edge, and the panel finding surface facing portion is The inner peripheral side and the outer peripheral side have an engaged portion with which the retrofitted bead is engaged, and the retrofitted bead is solidly formed, and the inner peripheral side engaged portion of the frame panel facing surface facing portion is An inner peripheral engaging portion that engages, and an outer peripheral engaging portion that engages with an outer peripheral engaged portion of the panel facing surface of the frame, and the outer peripheral engaging portion is made of a hard resin. In addition , the sash is characterized in that everything including the panel finding surface side and the inner peripheral side engaging portion side is made of a soft resin with respect to the other outer peripheral side engaging portions .
In the present invention, the frame includes ridges.

According to the first aspect of the present invention, since the outer peripheral side engaging portion is made of hard resin, the retrofitted bead is firmly engaged with the outer peripheral side engaged portion of the panel facing surface of the frame. Since the part other than the side engagement part is made of soft resin and solid, it is firmly sandwiched between the panel and the panel facing part by the elastic force, so even if it deteriorates over time, The attached post-bead can be prevented from falling by its own weight.
Since the post-attached bead is solid and made of a soft resin other than the outer peripheral side engagement, it can be easily inserted between the panel facing part of the frame and the panel so as to be crushed by elastic deformation, Moreover, since the outer peripheral side engaging portion is made of a hard resin, it is possible to push the outer peripheral side engaging portion into the outer peripheral side engaged portion of the panel panel finding surface portion while preventing the outer peripheral side engaging portion from being deformed or crushed. Thus, when the outer peripheral engaging portion is engaged with the outer peripheral engaged portion of the panel facing surface of the frame by pushing the retrofitted bead, a click feeling due to the return of elastic deformation can be obtained. The engagement of the joint can be easily confirmed. Therefore, the outer peripheral side engaging part of the retrofitted bead can be reliably engaged with the outer peripheral side engaged part of the panel facing surface of the frame.
Since the abutment surface of the retrofit bead and the inner peripheral side engaging portion are made of a soft resin, the water tightness can be improved by closely contacting these portions with the panel-facing surface facing portion of the panel and the frame. it can.
Since the rear bead is provided with an inner peripheral side engaging portion that engages with an inner peripheral side engaged portion of the panel facing surface of the frame, for example, when attached to the lower portion (lower frame) of the frame It is possible to prevent the retrofitted bead from falling to the frame side.
The retrofitted bead is made of a hard resin only for the outer peripheral side engaging portion, and the other portions are made of a soft resin that is less expensive than the hard resin. Therefore, it can be handled easily because it can be wrapped around a bead at the time of shipment.
The rear bead is made of hard resin only on the outer peripheral side engaging part that engages the outer peripheral side engaged part of the panel facing part of the frame, and other parts are made of soft resin, so the retrofitted bead is attached to the sash When the inner peripheral side engaging portion and the inner peripheral side portion of the same material are seen as the exposed portion, the exposed portion is one color, so the appearance is good.

As shown in FIG. 3, the retrofit bead 7 has an inner peripheral side contact part 35, an outer peripheral side contact part 37, and an inner peripheral side contact part 35 on the panel contact surface in a state before being attached to the sash 1. Intermediate contact portion 39 located between the inner contact portion 37 and the outer peripheral contact portion 37, and the inner peripheral contact portion 35 and the outer peripheral contact portion 37 are closer to the panel than the intermediate contact portion 39. It protrudes.
Between the inner peripheral contact portion 35 and the intermediate contact portion 39, an inner peripheral recess portion 41 that is recessed on the opposite side to the panel side is formed, and between the outer peripheral contact portion 37 and the intermediate contact portion 39. Is formed with an outer peripheral recess 43 that is recessed on the opposite side of the panel.
The tip end portion of the inner peripheral side abutting portion 35 is formed with an inclined surface 35a inclined so as to project toward the panel side toward the inner peripheral side, and the inclined surface 35a is inclined toward the outer peripheral side.
The outer peripheral side surface of the outer peripheral side contact portion 37 is formed with an inclined surface 37a inclined toward the inner peripheral side toward the distal end side of the outer peripheral side contact portion 37, and the inclined surface 37a is inclined toward the outer peripheral side. Yes.
On the outer peripheral side surface 7a of the main body portion 47 of the retrofitted bead 7, a guide portion 45 protruding from the outer peripheral side is formed. The guide portion 45 has an arrowhead shape protruding on the outer peripheral side by the inclined surface 37a of the outer peripheral side contact portion 37 and the outer peripheral side surface 47a of the main body portion 47 described above.

Next, construction and operational effects of the sash 1 according to the first embodiment will be described.
The construction of the sash 1 is performed by framing the upper frame 9, the lower frame 11, and the left and right eaves frames 13, 13 with the front beads attached to the outdoor panel finding surface facing portions 15 in the factory, and then the panel 5 in the frame 3. And a room-side panel finding surface facing portion (press edge) 17 is attached to the upper frame 9 and the left and right eaves frames 13 and 13.
Thereafter, the retrofit bead 7 is pushed in between each panel-side facing portion 17 of the indoor side panel and the panel 5 to mount the retrofit bead 7. Sequentially push into the facing surface facing portion 15. When the retrofitting bead 7 is pushed in, the guide part 45 of the retrofitting bead 7 is pushed in first. By pushing in, the bead 7 is deformed so that the soft resin portion is elastically deformed and the front end portion of the outer peripheral side contact portion 37 falls to the inner peripheral side on the panel contact surface, and the front end portion of the inner peripheral side contact portion 35 The intermediate contact portion 39 is pushed to the outer peripheral side while being pressed against the panel surface so as to be dragged to the outer peripheral side.
On the other hand, the outer peripheral side engaging portion 31 made of hard resin passes between the protruding portion 33 and the panel 5 with almost no deformation, and the outer peripheral side engaging portion 31 is the outer periphery of the indoor side panel finding surface facing portion 17. When the inner peripheral side engaging portion 29 is engaged with the inner peripheral side engaged portion 25 of the indoor side panel finding surface facing portion 17 while passing through the side engaged portion 27, the soft resin portion is elastically restored. Thus, the outer peripheral side engaging portion 31 engages with the outer peripheral side engaged portion 27 of the indoor side panel finding surface facing portion 17. When the outer peripheral side engaging portion 31 and the outer peripheral side engaged portion 27 are engaged, a gap S is formed as shown in FIG.
As described above, the attachment of the retrofit bead 7 to the indoor side panel finding surface facing portion 17 of the frame 3 is completed.

According to the present embodiment, since the outer peripheral side engaging portion 31 is made of hard resin, the retrofitted bead 7 is firmly engaged with the outer peripheral side engaged portion 27 of the indoor side panel finding surface facing portion 17, Since the portion other than the outer peripheral side engaging portion 31 is made of soft resin and solid, it is firmly sandwiched between the panel 5 and the indoor side panel finding surface facing portion 17 by its elastic force. Even when the aging deteriorates, it is possible to prevent the retrofitted bead 7 attached to the upper frame (upper part of the frame) 9 from dropping due to its own weight.
Since the post-attachment bead 7 is solid and made of a soft resin except for the outer peripheral side engaging portion 31, it is crushed by elastic deformation so that the space between the indoor panel-side panel detection surface facing portion 17 of the frame 3 and the panel 5 is reduced. Since the outer peripheral side engaging portion 31 is made of a hard resin, the outer peripheral side engaging portion 31 is prevented from being deformed or crushed while the outer peripheral side engaging portion 31 is placed on the indoor side of the frame 3. Since it can be pushed into the outer peripheral side engaged portion 27 of the panel facing surface facing portion, the outer peripheral side engaging portion 31 is brought into contact with the outer peripheral side engaged portion 27 of the indoor side panel finding surface facing portion 17 by the pushing of the retrofit bead 7. When engaged, a click feeling due to the return of elastic deformation can be obtained, and the engagement of the outer peripheral side engaging portion 31 can be easily confirmed. Therefore, the outer peripheral side engaging portion 31 of the retrofit bead 7 can be reliably engaged with the outer peripheral side engaged portion 27 of the indoor side panel finding surface facing portion 17 of the frame 3.
Since the post-attach bead 7 has a contact surface with the panel 5 and an inner peripheral side engaging portion 29 made of a soft resin, these portions are in close contact with the panel 5 and the indoor side panel finding surface facing portion 17 of the frame 3. Thus, water tightness can be improved.
The rear bead 7 is provided with an inner peripheral side engaging portion 29 that engages with the inner peripheral side engaged portion 25 of the indoor side panel finding surface facing portion 17 of the frame 3. It is possible to prevent the retrofitted bead 7 from falling to the frame side when it is attached to the lower part 11.
The retrofit bead 7 is made of a hard resin only for the outer peripheral side engaging portion 31 and the other portions are made of an inexpensive soft resin, so that it can be made inexpensive as a whole, and other than the outer peripheral side engaging portion 31 can be made of a soft resin. Therefore, it is easy to handle because the post-attached beads 7 can be wound and transported at the time of shipment.
Since only the outer peripheral side engaging portion 31 that engages with the outer peripheral side engaged portion 27 of the indoor side panel finding surface facing portion 17 of the frame 3 is made of hard resin, and other than that, it is made of soft resin. When the retrofit bead 7 is attached to the sash 1, the inner peripheral side engaging portion 29 and the inner peripheral side portion 7b made of the same material can be seen as an exposed portion, so that the exposed portion has one color, so that the appearance is good.

As shown in FIG. 3, the retrofitted bead 7 before mounting has the inner peripheral side abutting portion 35 and the outer peripheral side abutting portion 37 projecting more toward the glass side than the intermediate abutting portion 39. As described above, the panel 5 can be strongly pressed on the inner peripheral side and the outer peripheral side, so that the panel 5 is prevented from being inclined and a stable mounting posture of the panel 5 is easily maintained. Further, since a gap is hardly formed between the inner peripheral side contact portion 35 and the panel surface, the water tightness is high.
As shown in FIGS. 1 and 3, the retrofitted bead 7 is provided with the inner peripheral side concave portion 41, so that the inner peripheral side abutting portion 35 is more likely to fall down. Insertion between the facing portion 17 and the panel 5 can be easily performed. Similarly, since the outer peripheral side concave portion 43 is provided in the retrofitted bead 7, the outer peripheral side abutting portion 37 is more likely to fall down, so that the frame 3 is positioned between the indoor side panel finding surface facing portion 17 and the panel 5. Can be easily inserted.
The retrofit bead 7 is in close contact with the panel in a state where the inner peripheral side contact portion 35 and the outer peripheral side contact portion 37 are pushed down, and the intermediate contact portion 39 is in close contact with the panel in a state where the intermediate contact portion 39 is expanded. Since the gap between the panel 5 and the panel 5 is firmly held between the panel-side facing portion 17 and the panel 5 of the frame 3, even the outer peripheral engagement portion 31 and the inner Even if the engagement of the circumferential engagement portion 29 is loosened, it is possible to prevent the rear bead 7 itself from falling due to its own weight.
As shown in FIG. 3, the tip of the inner peripheral side abutting portion 35 of the retrofit bead 7 is provided with an inclined surface 35 a that is inclined so as to protrude toward the panel side toward the outer peripheral side, and the outer periphery of the outer peripheral side abutting portion 37. Since the inclined surface 37a inclined so as to protrude toward the panel is provided on the inner peripheral side, as shown in FIG. 1, when the retrofitted bead 7 is mounted, these inclined surfaces 35a and 37a are formed on the panel surface. Water tightness is good because it adheres along The inner periphery side contact portion 35 and the outer periphery side contact portion 37 are provided on the inner periphery side contact portion when the rear beat 7 is inserted between the indoor side panel finding surface facing portion 17 of the frame 3 and the panel 5. Since the inclined surface 35a of the portion 35 and the inclined surface 37a of the outer peripheral side contact 37 are inclined along the insertion direction, the outer peripheral side contact portion 37 and the inner peripheral side contact portion 35 are likely to fall down during insertion and These twists can be prevented.
Since the bead-shaped guide portion 45 is provided on the outer peripheral side surface of the retrofit bead 7, it is easy to insert the retrofit bead 7 into the narrow gap between the indoor-side panel detection surface facing portion 17 of the frame 3 and the panel 5. .
The retrofitting bead 7 has an inner peripheral side engaged portion 25 and an outer peripheral side formed in the indoor side panel locating surface facing portion 17 of the frame 3 with an interval K2 between the inner peripheral side engaging portion 29 and the outer peripheral side engaging portion 37. Since the gap S, which is the size of the difference, is formed slightly larger than the gap K1 between the engaged portion 27 and the soft resin portion elastically returns, the outer peripheral side engagement made of hard resin is performed. When the mating portion 31 engages with the outer peripheral engaged portion 27, the elastic resin portion can be reliably restored elastically and the outer peripheral engaging portion 31 can be engaged. Further, by making the gap S small, the lowering of the retrofit bead 7 can be reduced after the retrofit bead 7 is attached to the upper frame (upper part of the frame) 9.
