The side portions 82, 82 are locked in 3,79.

As shown in FIG. 6C, thin portions 75 on both sides are provided.
When the upper and lower connecting pieces 76 are cut off, the resin pieces 8
The surface 84 is exposed above and below the zero. By interposing the resin piece 80 having such a surface 84, the heat-insulated profile 70 that reduces the heat transfer between the indoor piece 72 and the outdoor piece 78 can be obtained. However, the indoor / outdoor pieces 72 and 78 of the aluminum alloy and the resin piece 80 that constitute the heat-insulated shape member 70 are different from each other due to the difference in the material properties between the two.

There is also a form. Even in the heat-insulated profile of this form, the resin piece is thermally shrunk along the longitudinal direction, thereby reducing the bonding strength in the same manner as described above, or forming a gap in the vicinity of a connection portion with another heat-insulated profile. Problem.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, makes it difficult for a resin piece forming a heat insulating structure to thermally shrink, and separates the resin piece from a metal part. It is an object to provide a heat-insulated profile which can prevent the occurrence of a gap with the other heat-insulated profile.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention moves a resin piece placed between metal parts inside and outside a room by heat shrinkage along substantially the entire length in the longitudinal direction. It was made with the idea of blocking.
That is, the heat-insulated profile of the present invention is a heat-insulated profile in which a resin piece is arranged between a metal indoor piece and an outdoor piece to form a heat-insulating structure. And a deformed portion that meshes with the resin piece is provided.
According to this, since the resin piece meshes with the irregularly shaped portion for each portion along the longitudinal direction, the heat shrinkage along the longitudinal direction is smaller than that of a conventional resin piece having the same cross section along the longitudinal direction. It can be suppressed significantly. Therefore, it is possible to prevent a decrease in bonding strength due to peeling from metal outdoor / indoor pieces and to prevent a gap from being formed between adjacently connected other heat-insulated members, and a fitting such as a sash having stable heat insulation performance. Can be formed.

[0007] The outdoor and indoor pieces are mainly made of extruded aluminum alloy, but other metal materials may be used as long as they meet the spirit of the present invention. Can be applied. Also,
The above-mentioned resin piece is formed into a hollow portion or a semi-hollow portion provided between the indoor piece and the outdoor piece, and is injected and solidified in a liquid state,
It also includes a form in which a required cross-sectional shape is formed in advance and both side edges are fixed to the outdoor piece and the indoor piece by caulking or the like.
Further, the material of the resin piece is not particularly limited as long as it has a property of thermally contracting like hard urethane, for example.

[0008] In addition, a heat-insulating shaped material in which the irregularly shaped portion has a substantially continuous corrugated shape or a substantially continuous uneven shape along the longitudinal direction of the resin piece is also included. According to this,
It is possible to reliably suppress the heat shrinkage of each portion of the resin piece extending over substantially the entire length in the longitudinal direction, and to maintain the bonding with the outdoor / indoor pieces firmly. Further, a heat-insulated shape member in which the irregularly shaped portion is formed on a flange or a rib integrally projecting from the indoor piece and / or the outdoor piece along the longitudinal direction of the resin piece is also included.

According to this, an irregularly shaped portion is formed on a flange or the like protruded from at least one of the indoor and outdoor pieces, and the resin piece and the resin piece are engaged substantially over the entire length. Heat shrinkage along the longitudinal direction of the piece can be suppressed more reliably. In this embodiment, the resin piece is injected and solidified into a hollow portion or a semi-hollow portion provided between the indoor piece and the outdoor piece, and at the same time, meshes with each part of the irregularly shaped portion of the indoor / outdoor piece. After being in a state,
The connecting piece forming the hollow portion or the like is cut off, and a part of the surface of the resin piece is exposed to the outside. In addition, when the indoor / outdoor piece is integrally formed with the connecting piece by extrusion molding, the flow of metal that passes through a flange or the like protruding toward the hollow portion side of the indoor / outdoor piece, for example, may be provided. The irregularly shaped portion having the continuous waveform can be formed so as to be non-uniform.

[0010] The irregularly shaped portion is formed as a long piece separate from the indoor piece and the outdoor piece, and the long piece is formed along the longitudinal direction of the resin piece with the indoor piece and / or the outdoor piece. Insulated profiles held in pieces are also included. According to this, a continuous waveform / concavo-convex shape along the longitudinal direction can be easily formed on a long piece having higher rigidity than the material of the resin piece. By injecting and solidifying the resin material in a state where the resin material is held at the position on the part side or the semi-hollow part side, it is possible to reliably form the irregularly shaped portion that engages with the long piece over the entire length of the resin piece.

Further, the irregularly shaped portion is formed as a long piece separate from the indoor piece and the outdoor piece, and the long piece is embedded in the resin piece over substantially the entire length in the longitudinal direction. , And heat-insulated profiles. According to this, before molding into a resin piece having a required cross-sectional shape in advance, a long piece having a corrugated / concavo-convex shape that is continuous along the longitudinal direction is inserted into the mold, and the resin material is removed. By injecting and solidifying, it is possible to reliably form a deformed portion that meshes with the long piece over the entire length of the resin piece without performing special processing on the indoor / outdoor piece. By fixing the resin pieces to the indoor / outdoor pieces at both side edges by caulking or the like, it is possible to obtain a heat-insulated profile having the resin pieces in which the heat shrinkage is suppressed. Or indoors
By arranging the long piece along the longitudinal direction in the hollow portion or semi-hollow portion between the outdoor pieces, and also by injecting and solidifying a resin material in such a hollow portion, the heat-shrinkable resin piece is suppressed. It is possible to obtain a heat-insulated profile having: In addition, as the material of the long piece, it is possible to apply a metal, ceramic, or the like, which has higher rigidity than the resin piece and has a thermal expansion coefficient equal to or smaller than that of the indoor / outdoor piece made of metal. . Thereby, the coefficient of thermal expansion of the entire resin piece can be controlled to the same degree as that of the indoor / outdoor piece, so that a shearing force is not generated or hardly generated on the bonding surface between them.

[0012]

Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1A shows an end face of a heat-insulated profile 1 made of an aluminum alloy constituting a sash frame. As shown in the figure, the profile 1 includes an indoor piece 2, an outdoor piece 12,
And a pair of upper and lower connecting pieces 6 for connecting the two, and a hollow portion 10 is formed between them. Each connecting piece 6 is connected to the indoor / outdoor pieces 2 and 12 via the thin portions 7 on both the inside and outside. The horizontal portions 3a and 15 of the indoor and outdoor pieces 2 and 12 adjacent to the thin portions 7 have hollow portions 1 and 2, respectively.
In the middle of the vertical walls 3 and 13 forming the hollow portion 10 of the indoor piece 2 and the outdoor piece 12, flanges 4 and 14 extending horizontally from the left and right face each other. It is protruding. Fig. 1 (B)
As shown in FIG. 2, the wavy shapes 8, 18 which are irregularly shaped portions in the present invention are formed continuously along the entire length of the flanges 4, 14 in the longitudinal direction.

In order to apply the corrugated shapes 8 and 18 to the flanges 4 and 14, for example, as shown in FIG. Of the port portion 24 located inside the portion 22 with a gap between the tip portion 27 of the flange forming groove 26
Is shorter than the length of the base end 28. That is, FIG.
In (b), the distance (the length) of the metal flow along the front-back (depth) direction is set shorter at the distal end 27 of the groove 26 and longer at the base end 28. As a result, a large amount of the aluminum alloy metal heated to the required temperature and softened flows toward the front end portion 27 of the flange forming groove 26, and flows only slightly toward the base end portion 28. Due to the non-uniformity of the metal flow, in the flanges 4 and 14 formed by the metal that has passed through the grooves 26, excess metal is cooled while waving along the vicinity of the tip 27, so that the flanges 4 and 14 Waveforms 8 and 18 waving more toward the tip
Can be formed.

Next, as shown in FIG. 1 (C), for example, a hard urethane liquid is injected into the hollow portion 10 of the profile 1 from one end thereof and solidified, so that the cross section follows the cross section of the hollow portion 10.

Can obtain the heat-insulated profiles 1 having a heat-insulating structure connected to each other only through the resin pieces 30. In FIG. 1 (A), even when the connecting piece 6 is located only below and the semi-hollow part (10) having an opening without the connecting piece 6 above, the material of the resin piece 30 is also removed from the opening. After pouring and solidifying along the longitudinal direction of the semi-hollow portion (10), the same heat-insulated profile 1 can be obtained by cutting off the lower connecting piece 6.

Accordingly, the indoor / outdoor piece 2, made of aluminum alloy,
In the case of 12, the heat transfer is prevented by the resin pieces 30, so that the indoor and outdoor directions can be insulated and the indoor temperature can be easily maintained without being affected by the outside air. Moreover, the resin piece 30 of the heat-insulated profile 1
As described above, the flanges 4, 1 of the indoor / outdoor pieces 2, 12 are provided.
