By the way, in each of the above-described composite type sliding windows, only a seal member and a single packing are installed between the resin frame on the outdoor side of the window frame and the resin cage on the indoor side of the shoji. It is easy to pass heat from the outside, such as cold air from the outside, and heat from the outside air is transferred to the indoor side from a metal rod such as a shoji aluminum alloy, so the exposed surface of the indoor side frame is cooled and condensed There is a drawback that may occur.
Particularly in cold regions, joinery is also required to have high heat insulation properties, but such a joinery with high heat insulation properties has not been provided in the past for metal and resin composite joinery.

  The present invention has been made in view of such problems, and in a composite joinery made of metal and resin, it suppresses heat conduction while ensuring airtightness between the shoji and the opening frame. An object of the present invention is to provide a composite joinery that improves heat insulation and dew proofing.

The composite joinery according to the present invention includes an opening frame body provided with a metal frame formed on the outdoor side and a resin frame formed on the indoor side, a metal cage that can be attached to the open frame body and formed on the outdoor side, and the indoor side. The first packing and the second packing are arranged with a gap on the outdoor side end surface of the resin frame between the resin frame of the opening frame and the resin cage of the shoji. The left and right resin vertical frames and the resin upper frame and the resin lower frame, the shoji of the shoji, the first packing, and the second packing are used to insulate the four circumferences between the opening frame and the shoji. The air layer which has property is formed.
According to the composite fitting according to the present invention, since the air layer of the sealed space is formed between the resin frame of the opening frame and the resin cage of the shoji through the first packing and the second packing, the shoji is placed in the opening frame. In the closed state, heat can be insulated by the air layer, heat transfer between the indoor and the outdoor can be reduced, and the temperature drop on the exposed surface of the indoor can be suppressed to prevent condensation. Moreover, the air layer can improve the heat insulation performance without adversely affecting the opening / closing operation and airtightness of the shoji.

Further, the air layer is characterized in that a gap that can maintain heat insulation is formed .
Since the air layer is formed with a gap communicating with the outside, a sealed space of the air layer can be secured, and it is easy to escape to the outside when excessive air pressure is applied in the air layer.

Moreover, it is preferable that said 2nd packing has the said clearance gap between the resin bottles of the said shoji.

The second packing is not continuous four times between the opening frame and the shoji.

Further, at least one of the first packing and the second packing may be formed to have a hollow portion, and another air layer may be formed in the hollow portion.
Thereby, a multilayer air layer is formed between the frame and the shoji by the air layer partitioned by the first packing and the second packing and another air layer formed in at least one of the hollow portions of the first and second packings. Since it can form, heat insulation performance improves further.

  According to the composite joinery of the present invention, since the air layer is formed by providing the first packing and the second packing between the resin frame of the opening frame and the resin cage of the shoji, the operation and airtightness of the shoji are affected. Without being able to improve heat insulation indoors and outdoors by the air layer, it is possible to suppress the heat from being transmitted from the outside to the indoors to cool or condense the interior.

  The frame 2 forms an opening frame composed of a metal frame 4 such as an aluminum alloy provided on the outdoor side and a resin frame 5 made of synthetic resin provided on the indoor side. The metal frame 4 is formed of left and right metal vertical frames 6 and 7, a metal upper frame 8, and a metal lower frame 9. The resin frame 5 includes left and right resin vertical frames 11 and 12 formed on the indoor side of the left and right metal vertical frames 6 and 7, a resin upper frame 13 formed on the indoor side of the metal upper frame 8, and a metal lower frame 9. It is comprised with the resin lower frame 14 formed inside. The metal upper frame 8 is separated into an outer metal upper frame portion 8a on the outdoor side and an inner metal upper frame portion 8b on the indoor side, and the outer metal upper frame portion 8a and the inner metal upper frame portion 8b are made of a resin bridge material. 10 are connected. Thereby, the heat transfer of the metal upper frame 8 can be reduced. Similarly, the metal lower frame 9 is separated into an outdoor-side outer metal lower frame portion 9 a and an indoor-side inner metal lower frame portion 9 b and is connected by a bridge member 15. Can be reduced.

  Moreover, the shoji 3 is comprised by the metal cage | basket 16 which consists of metals, such as an aluminum alloy provided in the outdoor side, and the resin-made resin cage | baskets 17 provided in the indoor side. The metal rod 16 is formed of left and right metal vertical rods 18 and 19, a metal upper rod 20 and a metal lower rod 21. The resin rod 17 includes left and right resin vertical rods 23 and 24 formed on the indoor side of the left and right metal vertical rods 18 and 19, a resin upper rod 25 formed on the indoor side of the metal upper rod 20, and the metal lower rod 21. It is comprised with the resin lower collar 26 formed inside. A glass body 31 made of, for example, double-layer glass is fitted inside the metal cage 16 and the resin cage 17 that are framed in a quadrilateral shape of the shoji 3.

  The shoji 3 of the vertically extending window 1 is placed in a closed state by contacting the left and right resin vertical frames 11, 12, the resin upper frame 13, and the resin lower frame 14 of the frame 2, and can be opened only outside the room. Has been. Further, in the shoji 3, a gremon handle 34 is provided as a main lock at the longitudinal center of the resin vertical rod 23 on the door end side (see FIG. 3), and the gremon handle 34 is provided on the metal upper frame 8 and the metal lower frame 9. And a receiving portion (not shown) that can be engaged with each other. A sub-block 36 is installed on the prospective surface of the lower part of the resin downpipe 23.

Further, in the lower frame portion of the frame body 2 shown in FIG. 3, a fitting recess 30 is formed on the outdoor side end surface 14 a of the resin lower frame 14 of the frame body 2, and the first packing 32 </ b> A is formed in the fitting recess 30. One end is fitted and the other end protrudes to the outdoor side. The first packing 32A has, for example, a substantially U shape, and a locking portion such as a protrusion for locking the tip of the first packing 32A may be provided on the end surface 26a of the resin lower collar 26. Further, a second packing 33A is formed so as to protrude further below the first packing 32A on the outdoor side end surface 14a of the resin lower frame 14, and in the example shown in the drawing, the second packing 33A is substantially downward. It has a bent or curved shape.
The first and second packings 32A and 33A are made of a soft material such as PVC (polyvinyl chloride), and the second packing 33A may be integrally formed with the resin lower frame 14, and in this case, the second packing 33A is formed. This portion is extruded with a softer resin than the resin lower frame 14.

  In the closed state in which the shoji 3 is housed in the frame 2, the tip of the first packing 32A is in contact with the indoor side end face 26a of the resin lower rod 26 of the shoji 3, and the tip of the second packing 33A is the end face. 26a (see FIG. 3) or slightly spaced (see FIG. 1). In this case, the first packing 32 is strongly pressed against the end surface 26a of the resin lower collar 26, and the second packing 33A is relatively lightly abutted against the indoor side end surface 26a of the resin lower collar 26, or is separated at least at a minute interval. It can be said that both are almost closed.

  Thus, an air layer 35A that forms a sealed space is formed by the resin lower frame 14, the resin lower collar 26, and the first and second packings 32A and 33A of the frame 2 in a longitudinal sectional view. The air layer 35A can insulate the frame 2 and the shoji 3 from heat, prevent heat such as outdoor cold air from being transmitted to the indoor side, and improve heat insulation and dew proofing. In addition, in the state in which the shoji 3 is closed to the frame 2, the resin lower rod 26 of the shoji 3 comes into contact with the first and second packings 32A and 33A, so that airtightness can be secured and the opening / closing operation of the shoji 3 is affected. Don't give.

  Further, the heat-insulating air layer 35A is formed not only between the resin lower frame 14 and the resin lower collar 26 but also between the resin upper frame 13 and the resin upper collar 25 as shown in FIG. In this case, the rib 32B is formed below the outdoor side end face 13a of the resin upper frame 13, and the packing 33B is formed above the rib 32B at an interval. An air layer 35B is formed by the packing 33B, the rib 32B, and the outdoor side end face 13a. The packing 33B and the rib 32B may be in contact with each other, but may be separated by a fine gap as shown in FIG. 1, and in any case, an air layer 35B in a sealed space can be formed.

  Similarly, as shown in FIG. 2, first packing 32C and 32D are respectively formed on the outdoor side end surfaces 11a and 12a of the left and right resin vertical frames 11 and 12, and the second packings 33C and 33D are spaced apart from each other. Are formed respectively. The first packing 32C, 32D strongly contacts the indoor side end faces 23a, 24a of the shovel 3 of the shoji 3 whose tips are closed, and the second packings 33C, 33D are the left and right resin hoists 23, 24. The end surfaces 23a and 24a are relatively weakly in contact with each other, or are separated by a minute interval. Therefore, the left and right resin vertical frames 11, 12 and the end faces 11a, 12a, 23a, 24a of the resin vertical rods 23, 24, and the first and second packings 32C, 32D, 33C, 33D, the air layer 35C in the sealed space, 35D is formed.

Therefore, the air layers 35A, 35C in the sealed space formed by the first packing 32A, 32C, 32D and the second packing 33A, 33C, 33D between the resin frame 5 of the frame 2 and the resin rod 17 of the shoji 3. 35D, the resin upper frame 13, the rib 32B, and the air layer 35B in the sealed space formed by the packing 33B, are formed in a frame shape that forms each side of a quadrangle.
In the figure, each of the first packings 32A, 32C, 32D is formed in a substantially U shape, and the second packings 33A, 33C, 33D and the packing 33B are formed in a substantially U shape or a J shape. However, each two packing can adopt arbitrary shapes. In the closed state of the shoji 3 with respect to the frame 2, the first packing 32A, 32C, 32D strongly abuts on the resin rod 17, and the second packing 33A, 33C, 33D is weakly abutted on the resin rod 17 or spaced apart at a small interval. It only has to be. As described above, the first packing 32A, 32C, 32D, the second packing 33A, 33C, 33D, the packing 33B, and the rib 32B are made of an elastic member such as a synthetic resin such as PVC softer than the resin frame 5 and the resin rod 17, or rubber. It has become.

The vertical window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next. In the vertical window 1 according to the present embodiment, the lock pin is engaged with the latch receiving portion by operating the main lock gremon handle 34 provided in the metal vertical rod 18 on the door side with the shoji 3 stored in the frame 2. It is combined. In this state, when the outdoor temperature is low, when cold air is transmitted from the metal fence 16 of the outdoor shoji 3 toward the indoor frame 2 side, it is insulated by the air layers 35A to 35D. Heat transfer to the indoor side of cold air is suppressed.
Moreover, the air layers 35A to 35D include the resin rod 17 of the shoji 3, the resin frame 5 of the frame 2, the first and second packings 32A, 32C, 32D, 33A, 33C, 33D, and the resin frame 5, the ribs 32B, and the packing. Since the sealed space is formed by 33B, and the sealed space does not have a metal material such as aluminum, the airtightness can be secured and the transmission of cold air can be suppressed, and the indoor exposed surface of the resin frame 5 of the frame body 2 can be suppressed. Temperature drop is suppressed and condensation is unlikely.

  As described above, according to the vertical extending window 1 according to the present embodiment, the soft first packing 32A, 32C, 32D and the second packing 33A are provided between the resin frame 5 of the frame 2 and the resin rod 17 of the shoji 3. , 33C, 33D, and the resin frame 5, ribs 32B, and packing 33B, the air layers 35A to 35D in the sealed space are formed, so that the heat insulating performance can be achieved without affecting the opening / closing operation of the shoji 3 and the airtightness in the closed state. Can be improved. Therefore, there is an effect that the temperature of the exposed surface of the resin frame 5 on the indoor side can be kept high and condensation is difficult to occur.

  Moreover, the second packings 33A, 33C, 33D are weaker than or in contact with the first packings 32A, 32C, 32D, and the ribs 32B and the packing 33B are also in contact with each other or have a slight gap. When the air pressure is excessively applied to the air layers 35A to 35D when the shoji 3 is closed, the second packing 33A, 33C, 33D and the packing 33B escape from the resin rod 17, so that the air pressure can be released. Moreover, even if the air in the air layers 35A to 35D thermally expands due to heat such as an increase in the outside air temperature or the room temperature, the tips of the second packings 33A, 33C, 33D, and the packing 33B having a weak contact force are the resin cages of the shoji 3 The air can be released away from the 17 and the rib 32B, and deformation or damage of the air layers 35A to 35D due to thermal expansion can be prevented.

The composite joinery according to the present invention is not limited to the vertical extending window 1 according to the first embodiment described above, and can be appropriately changed or replaced without departing from the gist of the present invention.
Although other embodiments and modifications of the present invention will be described below, the same or similar parts as those described in the above-described embodiments will be described using the same reference numerals.
For example, FIG. 4 is a lower longitudinal section of a terrace door 37 which is a composite joinery according to the second embodiment of the present invention. The terrace door 37 shown in FIG. 4 has the shoji 3 stored in the frame 2 in a closed state. And the recessed part 14b is formed in the upper part of the resin lower frame 14 provided in the metal lower frame 9 of the metal frame 4 of the frame 2, The one end of soft 1st packing 38A is fitted by this recessed part 14b, and the other end Protrudes in the outdoor direction and is in contact with the indoor side end face 26a of the resin lower casing 26 of the shoji 3.

  Further, in the metal lower frame 9, a recess 9a is formed at a position that contacts the outdoor side end surface 14a of the resin lower frame 14, and one end of the soft second packing 39A is fitted into the recess 9a, and the other end is in the outdoor direction. Projecting to the indoor side end face 26a of the lower plastic casing 26 of the shoji 3. The second packing 39 </ b> A has a frame shape with a hollow section inside, and its tip is in light contact with the indoor side end surface 26 a of the resin lower shell 26. The hollow portion of the second packing 39A forms a second air layer 41A. In addition, although the shape of the hollow part of the 2nd packing 39A was made into the rectangle in the figure, appropriate hollow shapes, such as circular and a polygon, are employable. The first and second packings 38A and 39A are made of the same material as the first and second packings of the first embodiment.

Further, the tip of the second packing 39A may be slightly separated from the end surface 26a of the resin lower collar 26, and in this case as well, the first air layer 40A is configured as a sealed space. The second packing 39A is supported by the recess 9a of the metal lower frame 9, but the sealed space constituting the first air layer 40A is formed by the resin lower frame 14, the resin lower collar 26, and the first and second packings 38A and 39A. It is formed and its thermal conductivity is small.
Therefore, in the lower part of the shoji 3, the first and second packings 38A and 39A are partitioned between the frame 2 and the shoji 3 by the end surface 14a of the resin lower frame 14, the end surface 26a of the resin lower rod 26, and the first and second packings 38A and 39A. An air layer 40A is formed, and further, a double air layer composed of a hollow second air layer 41A partitioned by the second packing 39A is formed.

  Accordingly, since the second packing 39A is weaker than the first packing 38A and is in contact with the resin lower shell 26 or has a slight gap, the air in the first air layer 40A is increased by an increase in the outside air temperature, the room temperature, etc., heat, or the like. Even if the thermal expansion of the second packing 39A, the tip of the second packing 39A having a weak contact force can move away from the resin lower collar 26 of the shoji 3 to allow air to escape, thereby preventing deformation or breakage of the first air layer 40A due to thermal expansion. Can do. The closed second packing 39A forming the second air layer 41A has no gap in the hollow portion, but the hollow portion of the second packing 39A may be divided to form a slight gap.

  In the terrace door 37 according to the second embodiment, the configuration including the first and second air layers 40A and 41A described above is not only the resin lower frame 14 of the resin frame 5 of the frame 2, but also the resin upper frame 13 and the left and right sides. The vertical air frames 40A and 41A can be formed on the four sides of the frame body 2 of the terrace door 37, respectively.

In the first embodiment described above, the air layer 35B is formed by the rib 32B, the packing 33B, and the resin frame 13, but the same configuration as the other air layers 35A, 35C, and 35D may be adopted.
In each of the above-described embodiments, the first packing and the second packing, or the packing and ribs, an air layer for heat insulation between the resin frame on the upper, lower, left and right sides of the frame 2 and the shoji 3 and the resin cage. However, the air layer is not necessarily formed on all sides, and may be formed only on a part of the sides. In that case, it is preferable to form an air layer between the lower resin lower frame 14 and the lower resin rod 26, which are easy to transmit cold air from the ground and have a relatively low temperature.
Further, the arrangement of the first packing and the second packing or the packing and ribs on each side forming the air layer may be exchanged.

  Moreover, when forming an air layer, it is not limited to two air layers of one air layer 35A-35D or the first air layer 40A and the second air layer 41A, but three or more air layers are formed. It may be formed. Or you may change the air layer installed by each edge | side into one layer, two layers, etc. In the second embodiment described above, the second packing 39A has the hollow second air layer 41A. Instead, the first packing 38A has the second air layer 41A having a hollow portion. May be. Further, both the first packing 38A and the second packing 39A may have a hollow air layer. In this case, a three-layer air layer is formed, and the heat insulation is further improved.

  In addition, the composite joinery comprising metal and resin according to the present invention can be used not only for the vertical extending window 1 and the terrace door 37 but also for various types of windows and doors such as a horizontal extending window, a sliding window, and a sliding door. It goes without saying that it can be adopted.
