  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1-3 has shown 1st Embodiment of the fitting of this invention. This joinery is a wind-collecting door installed at a door, etc., and is supported by a frame 8 attached to the opening of the frame so as to open to the outdoor side with a hinge 9, and is suspended from the upper eaves 10 and the lower eaves 11. A rectangular casing is constructed by assembling the former fence 12 and the door-end fence 13 four times, and a raising / lowering window 16 composed of an external reed 14 and an internal reed 15 is provided at the opening of the enclosure. The outer shoji 14 and the inner shoji 15 are connected by an interlocking mechanism (not shown) using a wire and a pulley, and when the inner shoji 15 is raised, the outer shoji 14 descends in conjunction with this, and Wind can be collected through an opening formed below the shoji 15.

As shown in FIGS. 1 and 2, the frame 8 is formed of a resin shape 17 at the interior side, and a tight material 18 that closes the gap between the door and the door is attached to the outside surface of the resin shape 17. .
As shown in FIGS. 1 and 2, the upper rod 10, the lower rod 11, the hanging rod 12, and the door rod 13 constituting the frame are formed with aluminum shapes 19 a, 19 b, 19 c, 19 d on the outdoor side, The indoor side is formed of resin shape members 20a, 20b, 20c, and 20d. Each of the resin shape members 20a, 20b, 20c, and 20d is provided with a large number of partition walls 21 inside, and the internal space is finely partitioned. Each of the scissors 10, 11, 12, and 13 has a groove 7 that opens to the inner peripheral side and squeezes the peripheral edge of the outer / inner limbs 14 and 15.

As shown in FIGS. 1 and 2, the outer shoji 14 and the inner shoji 15 are constructed by assembling an upper collar 2, a lower collar 3, and left and right collars 4, 4 into a rectangular shape, and the multilayer glass 1 in the frame. Installed and configured. Each of the folds 2, 3 and 4 of the shojis 14 and 15 is formed of aluminum profiles 22a, 22b and 22c on the outdoor side, and the resin profiles 23a, 23b and 23c on the indoor side, except for the lower ledge 3 of the shoji 14. It is formed with. The resin shape members 23a, 23b, and 23c are each provided with a partition wall 24, and the internal space is finely partitioned. Since the lower arm 3 of the external shoji 14 overlaps the outdoor side of the upper arm 2 of the inner shoji 15, the entirety is formed of an aluminum shape.
Each of the flanges 2, 3, 4 has a panel holding groove 5 opened on the inner peripheral side, and the multilayer panel 1 is interposed between the outdoor side wall 5 a and the indoor side wall 5 b of the panel holding groove 5 via a bead 27. Holding. The interior side wall 5b and the bottom 5c of the panel holding groove 5 are made of resin (except for the lower collar 3 of the external shoji 14), of which the interior side wall 5b of the panel retaining groove 5 of the upper collar 2 and the collar 4 is removable. It is a free ledge.
The outer shoji 14 and the inner shoji 15 are assembled with the upper eyelid 2, the lower eyelid 3, and the left and right eyelids 4, 4 without the double-glazed glass 1, With the pressing edge 5b removed, the multilayer glass 1 is inserted into the panel holding groove 5 from the indoor side so as to rotate from the lower side to the outdoor side. Therefore, in order to prevent the edge of the double-glazed glass 1 from hitting and breaking when the double-glazed glass 1 is inserted, compared with a general sash shoji that fits the double-glazed glass through a glazing channel. Thus, the space in the glass holding groove 5 of each of the ridges 2, 3, and 4 is widened. The space in the glass retaining groove 5 of the upper collar 2 and the collar 4 is wider than the space in the glass retaining groove 5 of the lower collar 3.

  The bottom portion 5c of the panel holding groove 5 of the upper collar 2 and the collar 4 has a fin piece 6 made of a soft resin projecting from the intermediate portion in the indoor / outdoor direction toward the inner peripheral side. The front end is in contact with the fore edge 1a of the multilayer glass 1. This fin piece 6 is integrally formed with the resin shape members 23a and 23c constituting the flanges 2 and 4. Further, the fin piece 6 is slightly inclined toward the indoor side, so that the tip of the fin piece 6 that contacts the small edge 1a of the multilayer glass 1 always bends to the indoor side. The fin piece 6 is provided on the indoor side with respect to the aluminum shape members 22a and 22c arranged on the outdoor side of the bag. By providing the fin pieces 6 in the panel holding groove 5 in this way, the space in the panel holding groove 5 is divided into two in the indoor / outdoor direction. The indoor space 33 partitioned by the fin piece 6 is insulated by being surrounded by a member having a small thermal conductivity, such as the resin fin piece 6, the resin shape members 23a and 23c, the resin pressing edge 5b, and the multilayer glass 1. It is a space.

This joinery is formed by forming the indoor side portions of the frame 8 and the frames 2, 3, 4, 10, 11, 12, 13, etc. with the resin shapes 20 a, 20 b, 20 c, 23 a, 23 b, 23 c In addition to the heat insulation effect due to the fact that the heat transfer through the glass is suppressed and the use of the multi-layer glass 1, as described above, the fin piece made of a soft resin extends from the bottom 5c of the panel holding groove 5 to the small opening 1a of the multi-layer glass 1. 6 is provided and the space in the panel holding groove 5 is partitioned in the indoor / outdoor direction, heat transfer due to air convection in the panel holding groove 5 is hindered, so that the heat insulation performance can be further improved. In particular, when the space in the panel holding groove 5 of the eaves 2, 3 and 4 is wide as in the joinery of this embodiment, providing the fin pieces 6 in this manner is effective in improving the heat insulating performance. .
Since the fin piece 6 is provided on the indoor side of the aluminum shape members 22a and 22c, warm air can be confined to the indoor side, which is effective in improving the heat insulating performance. As will be described later, when a plurality of fin pieces 6 are provided in the indoor / outdoor direction, it is sufficient that at least one fin piece 6 is located on the indoor side of the aluminum shape members 22a and 22c.
Furthermore, since the indoor space 33 divided by the fin pieces 6 is an insulated space surrounded by a member having a low thermal conductivity such as resin, the heat of warm air confined in the space is surrounded by It is effective in preventing escape from traveling along the wall and improving the heat insulation performance.

FIG. 13 is a heat stream diagram showing the result of the simulation of heat transfer performed for the joinery of the first embodiment. The simulation was performed under conditions of external 0 ° C. and internal 20 ° C. The thin lines shown in the figure indicate heat flow lines, and the interval per line is 0.1 W / m. If the heat stream lines are dense, it means that the amount of heat moving is large, and if the heat stream lines are separated, the amount of heat moving is small. For comparison, the same simulation was performed for the panel holding groove 5 in which the fin piece 6 was not provided. The result is shown in FIG.
Comparing FIG. 13 and FIG. 14, the one in FIG. 13 in which the fin piece 6 is provided in the panel holding groove 5 appears in the panel holding groove 5 as compared with the one in FIG. 14 in which the fin piece 6 is not provided. The interval between the heat stream lines is wide and the number of heat stream lines is small. From this, it can be seen that the heat flow in FIG. 13 is less, that is, the heat insulation performance is high. In FIGS. 13 and 14, heat flow lines are concentrated in the aluminum shape member 22 c arranged outside the bag, and the heat in the panel holding groove 5 escapes to the aluminum shape member 22 c where the heat flow lines are dense. As shown in FIG. 13, it is meaningful to partition with a fin piece 6 on the indoor side.

  As described above, the fin piece 6 is provided across the bottom portion 5c of the panel holding groove 5 and the small edge 1a of the multilayer panel 1, and the space in the panel holding groove 5 is divided into the interior and the outside of the panel holding groove 5. Since heat transfer due to air convection is hindered, heat insulation performance can be improved. Since the fin piece 6 is formed of a soft resin and is flexibly deformed, there is no problem in attaching the multi-layer glass 1, and there is no possibility that the edge of the glass 1 is broken. Further, the fin piece 6 is integrally formed with the resin shape members 23a and 23c constituting the flanges 2 and 4, so that it is not necessary to separately attach the fin piece 6 later and the cost is low. Further, by providing the fin piece 6 in the panel holding groove 5 in this way, it is possible to prevent rainwater from flowing into the room, so that the watertight performance can be improved. In the panel holding groove 5 of the lower lid 3 of the shoji 14 and 15, no fin piece 6 is provided in consideration of drainage of rainwater or the like that has entered the panel holding groove 5, but the panel holding groove 5 of the lower lid 3 is not provided. The thermal insulation performance can be further improved by providing the fin pieces 6 therein. In this case, if a hole or a notch for drainage is provided in the fin piece 6 in the panel holding groove 5 of the lower rod 3, there is no problem in drainage.

  In the above-described embodiment, the tip of the fin piece 6 is in contact with the fore edge 1a of the multilayer glass 1, but there may be a slight gap between the tip of the fin piece 6 and the fore edge 1a of the multilayer glass 1. . The size of the gap is preferably 2 mm or less. If the size of the gap is 2 mm or less, air convection can be prevented as in the case of contact, and the heat insulation performance can be improved.

  Further, as shown in FIG. 1, this joinery has a fin piece 28 made of a soft resin hanging down at an intermediate position in the indoor / outdoor direction of the outer peripheral side surface (lower surface) of the lower collar 3 of the inner sward 15. A tip 28 abuts against a bottom surface of the groove 7 of the lower collar 11 of the door body, and a space in the groove 7 is partitioned indoors and outdoors by a fin piece 28. Thereby, since the heat transfer by the convection of the air in the groove | channel 7 is inhibited like the case where the fin piece 6 is provided in the panel holding groove | channel 5, the heat insulation performance improves. Further, the watertight performance is improved by preventing the rainwater from flowing indoors by the fin pieces 28. The fin piece 28 is integrally formed with the resin profile 23b constituting the lower collar 3 of the shoji 15, so that it is not necessary to separately attach the fin piece 28 later, and the cost is low. Since the fin piece 28 deforms flexibly, it does not hinder the opening and closing of the shoji 15. Since the fin piece 28 is disposed on the indoor side with respect to the aluminum shape member 22b disposed on the outdoor side of the bag, warm air can be confined to the indoor side, and there is an effect of improving heat insulation. Moreover, since the indoor space 34 divided by the fin pieces 28 is an insulated space surrounded by a member having a low thermal conductivity such as a resin, the heat of warm air confined in the space 34 is generated. It is effective in preventing the escape through the surrounding walls and improving the heat insulation performance.

4 and 5 show a second embodiment of the joinery of the present invention. In this embodiment, two fin pieces 6 a, 6 b are provided in the interior and exterior direction at intervals from the bottom 5 c of the panel holding groove 5 toward the small edge 1 a of the multilayer panel 1, and the indoor side wall of the panel holding groove 5 is further provided. A fin piece 6 c is also provided on the pressing edge constituting 5 b, and the fin piece 6 c is in contact with the indoor side of the multilayer panel 1. That is, in this embodiment, a total of three fin pieces 6a, 6b, 6c are provided in the panel holding groove 5, and the space in the panel holding groove 5 is partitioned into four in the indoor and outdoor directions. Each fin piece 6a, 6b, 6c is formed integrally with the resin shape members 23a, 23c and the pressing edge 5b.
According to this embodiment, since the space in the panel holding groove 5 is finely partitioned in the indoor / outdoor direction, the heat insulation performance can be further improved.

6 and 7 show a third embodiment of the joinery of the present invention. In this embodiment, a soft protrusion 29 having a substantially semicircular cross section is provided on the bottom 5 c of the panel holding groove 5, and the top of the soft protrusion 29 is in contact with the small edge 1 a of the multilayer panel 1. The soft protrusion 29 is integrally formed with the resin shape members 23a and 23c constituting the flanges 2 and 4.
According to the present embodiment, in addition to partitioning the space in the panel holding groove 5 by the soft protrusion 29, the air inside the soft protrusion 29 is sealed, so that the heat insulation performance is further improved.

8 and 9 show a fourth embodiment of the joinery of the present invention. In this embodiment, a tight material holder 30 is provided at the bottom 5c of the panel holding groove 5, and three fin pieces 6a, 6b, 6c are provided on the tight material 31 passed through the tight material holder 30 so as to be separated from each other in the indoor and outdoor directions. The fin pieces 6a, 6b, 6c are in contact with the edge 1a of the multilayer glass 1.
According to the present embodiment, the space in the panel holding groove 5 is finely partitioned in the indoor / outdoor direction as in the second embodiment, so that the heat insulation performance is further improved. Further, even when the entire panel holding groove 5 is made of aluminum, the fin pieces 6a, 6b, 6c can be easily installed in the panel holding groove 5.

10-12 has shown 5th Embodiment of the fitting of this invention. This joinery is a coffin door installed at a door, etc., and is supported on a frame 8 attached to the frame opening so as to open to the outdoor side with a hinge 9, and is hung with an upper coffin 10 and a lower coffin 11. A rectangular frame is constructed by assembling the main fence 12 and the door-end fence 13 on four sides, and the panel holding groove 5 formed on the inner peripheral side of each of the fences 10, 11, 12, 13 is formed with gray. The multi-layer glass 1 is fitted through a ging channel 32.
As shown in FIGS. 10 and 11, the glazing channel 32 has two fin pieces 6 a and 6 b projecting on the outer peripheral side face away from each other in the indoor and outdoor directions, and each fin piece 6 a and 6 b is the bottom of the panel holding groove 5. 5c.
The joinery of the present embodiment also has an effect of improving the heat insulation performance by partitioning the space in the panel holding groove 5 into a plurality of indoor and outdoor directions by the fin pieces 6 a and 6 b protruding from the glazing channel 32. By providing the fin pieces 6a and 6b integrally with the glazing channel 32, it is possible to improve the heat insulation performance of all window types simply by winding the glazing channel 32 around the glass 1.

  About the 1st-4th embodiment of the wind door demonstrated above, and the 5th embodiment of the coffin door, the heat transmissivity was calculated | required by calculation. Further, as Comparative Example 1, the heat transmissivity is also obtained for the wind door without the fin pieces 6 in the panel holding groove 5 and as the comparative example 2 with the saddle door having no fin pieces 6 in the panel holding groove 5. Then, the difference in the heat transmissivity between each embodiment and the comparative example was obtained. The results are shown in Table 1 below.

  As is clear from Table 1, the first embodiment of the wind-collecting door has a smaller heat transmissivity than the comparative example 1 without the fin pieces 6 and has excellent heat insulation performance. The second and fourth embodiments in which a plurality of fin pieces 6 are provided, and the third embodiment in which a semicircular soft protrusion 29 is provided have a smaller heat transmissibility and better heat insulation performance than the first embodiment. . The fifth embodiment of the coffin door has a smaller heat transmissivity than the comparative example 2 without the fin pieces 6 and has excellent heat insulation performance.

  Further, in order to investigate the influence of the position of the fin piece 6, as shown in FIGS. 15 (a) to 15 (c), when the fin piece 6 is provided closer to the outdoor side, the fin piece 6 is arranged at the substantially center in the indoor / outdoor direction. In the case where the fin pieces 6 are provided closer to the indoor side (both wind-collecting doors), the heat transmissivity was obtained by calculation. For comparison, the heat transmissivity was also obtained for those without the fin pieces 6. The results are shown in Table 2 below.

  As is clear from Table 2, the heat transmissivity is smaller when the fin piece 6 is provided at the position closer to the outdoor side, at almost the center in the indoor / outdoor direction, or closer to the indoor side than in the case where the fin piece 6 is not provided. It can be seen that the heat insulation performance is improved. In particular, when the fin piece 6 is arranged at the substantially center in the indoor / outdoor direction, the effect is remarkable as compared with the case where the fin piece 6 is arranged near the outdoor side or the indoor side. In this way, the heat insulation performance can be further improved by partitioning the space into almost half by the fin pieces 6.

  The present invention is not limited to the embodiments described above. The frame may be one in which the outdoor side and the indoor side are made of aluminum and a resin bridge member is provided in the middle, or the whole is made of resin or aluminum. The panel does not necessarily need to be a double-glazed glass. The present invention can be applied to any joinery, not limited to a wind door and a coffin door.
