  TECHNICAL FIELD The present invention relates to various composite fittings such as a composite type squeezed window, a door, and a sliding shoji provided with a frame having a metal frame and a resin frame and a shoji having a metal cage and a resin cage.

2. Description of the Related Art Conventionally, as a composite fitting including a frame body in which a metal such as aluminum and a resin are joined and a shoji, a composite extended window described in Patent Document 1 has been proposed. In this horizontal type composite window, a metal frame is formed on the outdoor side of the window frame forming the opening, and a resin frame is formed on the indoor side. And the shoji attached to a window frame so that opening and closing is possible, the metal cage | basket is formed in the outdoor side, and the resin cage | basket is formed in the indoor side. This shoji has multi-layer glass fitted in a box that is assembled into a quadrangle by upper and lower ridges and left and right vertical folds.
In such an open window or the like, the heat insulation is improved by covering the metal frame with a resin frame when viewed from the indoor side, and the aesthetics are improved by preventing the metal such as aluminum from being seen from the room.

  Moreover, in the composite sliding window described in Patent Document 2, the upper and lower frames and the left and right vertical frames of a frame framed in a quadrangle that houses a shoji are connected to the outdoor metal frame portion and the indoor metal frame. Each was divided into parts, and these were connected and arranged via a resin bridge material. As a result, the outdoor metal frame part and the indoor metal frame part are thermally insulated by the bridge material, the heat transfer between the indoor and the outdoor by the metal frame is blocked by the bridge material, and the heat insulation inside and outside is set high. Yes.

  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 vertical 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 only on the outdoor side. It can be opened. Further, in the shoji 3, a gremon handle 34 is provided as a main lock at the longitudinal center of the metal vertical rod 18 on the door tip side, and the gremon handle 34 is provided on the metal upper frame 8 and the metal lower frame 9 on the door tip side. A receiving portion that can be engaged with the locking component is provided (not shown). A sub-block 36 is installed on the prospective surface of the lower part of the resin vertical rod 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.

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 set to be relatively lightly abutted against the end surface 26a of the resin lower collar 26 or separated at a minute interval. All of them 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 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. Therefore, the outdoor side end face 13a of the resin upper frame 13, the rib 32B, and the packing 33 form an air space 35B in a sealed space.
Similarly, the first packing 32C and 32D are respectively formed on the outdoor side end faces 11a and 12a of the left and right resin vertical frames 11 and 12, and the second packings 33C and 33D are formed at intervals inside thereof.

It only has to be. The first packing 32A, 32C, 32D, the second packing 33A, 33C, 33D, and the packing 33B are made of a synthetic resin such as PVC (polyvinyl chloride) or an elastic material such as rubber.

Next, in the upper frame part of the frame 2 shown in FIG. 4, the metal upper frame 8 of the metal frame 4 is separated from the outer metal upper frame 8a on the outdoor side and the inner metal upper frame 8b on the indoor side on the upper side. Moreover, they are connected with a resin bridge member 37 interposed therebetween. Therefore, heat such as outdoor low temperature transmitted to the outer metal upper frame 8a is blocked by the bridge member 37 and is not transmitted to the inner metal upper frame 8b. The bridge member 37 may have any shape, but is formed to have a wide width so that heat is not transferred between the outer metal upper frame 8a and the inner metal upper frame 8b.
In the example shown in FIG. 4, the bridge member 37 has a substantially polygonal frame shape having a hollow portion 37a inside, for example, a hexagonal cross-sectional frame shape, and ends of the outer metal upper frame 8a and the inner metal upper frame 8b at both ends thereof. Convex parts 37b and 37c which fit into concave parts 38a and 38b formed in the part. Also, the outer metal lower frame 9a on the outdoor side and the inner metal lower frame 8b on the indoor side are separated from each other and connected with the resin bridge member 15 in between.

Further, the lattice-like portion 40 in which the plurality of air chambers 39 a are formed may be provided also on the left and right vertical frames of the frame body 2.

  Moreover, the resin upper frame 13 formed on the indoor side of the inner metal upper frame 8b forms a lattice-like portion 40 that partitions the air chambers 39a (first air chambers) having a plurality of square cross sections that are different in size, and is partitioned by the resin. The plurality of air chambers 39a thus formed constitute a heat-insulating sealed space. The lattice-shaped portion 40 of the resin upper frame 13 is formed in a region facing at least one of the outer metal upper frame 8a, the bridge member 37, and the inner metal upper frame 8b on the indoor side, and here, the shoji 3 Rather than the indoor side. In particular, by installing the air chamber 39a at a position facing the bridge member 37, the heat transfer heat insulation is further enhanced.

  The air chambers 39a partitioned by the lattice-like portion 40 are formed in various sizes, but the air chambers 39a may be arranged in the vertical and horizontal directions in the same size. The portions 40 are formed in a lattice shape having the same dimensions. In addition, the lattice-like portions 40 are configured so that the air chambers 39a are arranged in the vertical and horizontal directions, but may be formed only in the vertical direction or in the horizontal direction. Even in these cases, the heat insulation can be enhanced by the plurality of air chambers 39a. Thus, in the space between the shoji 3 and the outer metal upper frame 8a of the metal upper frame 8, the bridge member 37, and the inner metal upper frame 8b, a plurality of air chambers 39a partitioned by the lattice portion 40 are installed. Therefore, it is possible to reduce the transfer of heat through this space.

Further, the lattice-like portion 40 of the resin upper frame 13 is formed by projecting a plurality of protrusions 40a protruding above the air chamber 39a on the surface facing the outer metal upper frame 8a, the bridge member 37 and the inner metal upper frame 8b.

Also by the air chamber 42, the plurality of protrusions 40a are arranged at predetermined intervals in a region facing the outer metal upper frame 8a, the bridge member 37, or the inner metal upper frame 8b, so that heat is generated between the outdoors and the indoors. It is possible to suppress the movement of the material and improve the heat insulation performance.
In particular, one or more (two in the figure) protrusions 40a are provided at positions facing the bridge member 37, and these protrusions 40a make the air chamber 42 an outdoor air chamber 42 and an indoor air chamber 42. It is divided into. As a result, a plurality of air chambers 42 are formed between the bridge member 37 that blocks the movement of heat and the protrusions 40a, so that the movement of air can be suppressed between the outdoor side and the indoor side. Moving to the indoor side can be suppressed.
Furthermore, as described above, the air layer 35B is also formed on the outdoor side of the lattice-like portion 40 of the resin upper frame 13, and this also suppresses the movement of heat indoors and outdoors, so that the heat insulation is improved. . Further, the lattice portion 40 and the plurality of air chambers 39 b are also formed on the resin upper collar 25 and the resin lower collar 26.

Further, in the present embodiment, the lattice-like portion 40 including the large and small air chambers 39 a described above is also formed on the resin lower frame 14. The lattice-shaped portion 40 of the resin lower frame 14 is formed by projecting a plurality of protrusions 40b protruding below the air chamber 39a on the surface facing the outer metal lower frame 9a, the bridge member 15 and the inner metal lower frame 9b. An air chamber 44 (second air chamber) capable of storing air is provided in the recesses between the outer metal lower frame 9a, the bridge member 15 and the inner metal lower frame 9b, and the plurality of protrusions 40b of the lattice-shaped portion 40.

Also with this air chamber 44, heat is transferred between the outdoors and indoors by arranging a plurality of protrusions 40b at predetermined intervals in a region facing the outer metal lower frame 9a, the bridge member 15 or the inner metal lower frame 9b. It is possible to further improve the heat insulation performance.
Further, the protrusion 40 b is provided at a position facing the bridge member 15, thereby dividing the air chamber 44 into an outdoor air chamber 44 and an indoor air chamber 44 by the protrusion 40 b. As a result, a plurality of air chambers 44 are formed between the bridge member 15 that blocks the movement of heat and the protrusions 40b, and air movement can be reduced between the outdoor side and the indoor side, for example, from the outdoor side to the indoor side. The movement of cold air can be suppressed.

The composite joinery according to the present invention is not limited to the vertical extending window 1 according to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention.
Hereinafter, modifications of the present invention will be described, but the same or similar components or members described in the above-described embodiment will be described using the same reference numerals.

  For example, in the embodiment described above, (1) the outer metal upper and lower frames 8a and 9a divided by the bridge members 37 and 15 and the inner metal upper and lower frames 8b and 9b are connected to the metal upper and lower frames 8 and 9 of the frame body 2, (2) A plurality of air chambers 39a and 39b further partitioned by the lattice-like portion 40, and (3) the bridge members 37 and 15, the outer metal upper and lower frames 8a and 9a or the inner metal upper and lower frames 8b and 9b and the lattice-like portion 40. All three sets of the concave air chambers 42 and 44 provided between the two are provided, but the present invention is not limited to such a configuration.

  For example, (2) only a plurality of air chambers 39a and 39b partitioned by the grid portion 40 may be provided, or (3) a resin upper and lower frame facing the metal upper and lower frames 8 and 9 without the bridge members 37 and 15. Protruding portions 40 a and 40 b may be provided on 13 and 14, and only the recessed air chambers 42 and 44 may be provided between the metal upper and lower frames 8 and 9. Alternatively, a combination of (1) and (2), a combination of (1) and (3), or a combination of (2) and (3) may be provided.

  In the above-described embodiment, the first packing 32A to 32D and the second packing 33A to 33D are used for heat insulation between the resin frame on the four sides of the frame 2 and the shoji 3 and the resin frame and the resin basket. Although the layers 35 </ b> A to 35 </ b> D are formed, it is not always necessary to form an air layer 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 35 </ b> A between the lower resin lower frame 14 and the lower resin lid 26, which is easy to transmit cold air from the ground and has a relatively low temperature.

  Further, when the air layers 35A to 35D are formed by the first packing 32A, 32C, 32D and the second packings 33A, 33C, 33D, and the packing 33B, the first packing is used instead of the configuration in which one air layer 35A to 35D is provided. 32A, 32C, 32D or / and the second packing 33A, 33C, 33D, packing 33B may be formed into a shape having an air layer composed of a hollow portion, so that two to three air layers may be formed. In this case, the heat insulation is further improved.

  Moreover, although the composite joinery provided with the metal and the resin according to the present invention is used for the vertical extension window 1 as an embodiment, it is not limited to this, and the horizontal extension window, the sliding window, the sliding door, etc. Needless to say, it can be used in composite joinery such as various windows and doors.
