Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulated profile used for various sashes.

[0002]

2. Description of the Related Art Conventionally, as the above-described heat-insulated profiles, for example, an indoor-side profile, an outdoor-side profile provided opposite to the indoor-side profile, and a plurality of long sections connecting the two profiles. Some are equipped with a heat-insulating material in the form of a scale, and a heat-insulating resin such as foamed polystyrene or urethane foam is provided in the space formed between the two shaped members and the heat-insulating material facing away from each other. It is.

[0003]

However, in the above-mentioned conventional heat-insulating profiles, a heat-insulating resin such as expanded polystyrene is provided in the space between the two profiles and the heat-insulating material facing each other. Although it is possible to realize the improvement of the above, at the time of manufacturing, after connecting the indoor side profile and the outdoor profile with a plurality of heat insulating materials, it is necessary to perform an operation of filling the space with a heat insulating resin. In addition, there is a problem that the manufacturing cost is increased as much as the material cost and the number of man-hours are increased, and it has been a conventional problem to solve this problem.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a heat-insulated profile capable of realizing an improvement in heat insulation performance and also realizing a reduction in manufacturing cost.

[0005]

According to a first aspect of the present invention, there is provided a heat-insulated section, wherein an indoor section, an outdoor section provided opposite to the indoor section, and both sections are connected. A plurality of long-sized heat insulating materials are provided, and at least one of the heat insulating materials facing each other at a distance from each other, projecting toward the other heat insulating material, and protruding between the two shaped materials and both the heat insulating materials. The space is provided with a protruding portion along the longitudinal direction that blocks the space in the indoor and outdoor directions, and the configuration of the heat-insulated profile is used as means for solving the conventional problems.

[0006] In the heat-insulated profile according to claim 2 of the present invention,
The protrusions are provided on both of the heat insulating materials facing each other at an interval.

According to a third aspect of the present invention, there is provided a heat-insulated profile.
The projections provided on both of the heat insulating materials facing each other at an interval are configured to face each other, and the heat insulating profiles according to claim 4 of the present invention are provided on both of the heat insulating materials facing each other at an interval from each other. The projections are configured to overlap in the indoor and outdoor directions.

In the heat-insulated profile according to the present invention, the projection is brought into contact with the intermediate portion of the heat-insulating material, the tip of the projection, or the indoor / outdoor surface to form a space between the two profiles and the heat-insulating material. When the projection is shielded in the indoor / outdoor direction, and when the protrusion faces the intermediate portion of the heat insulating material and the tip of the protrusion or the indoor / outdoor surface with a space therebetween, the distance between both the shaped material and the heat insulating material is reduced. This includes both cases where the space is blocked in the indoor and outdoor directions.

[0009]

According to the heat-insulating profile according to the first aspect of the present invention, since there is a difference between the ambient temperature at which the indoor-side profile is exposed and the ambient temperature at which the outdoor-side profile is exposed, The protrusions will block convection and heat radiation generated in the space formed between both the shape members and both the heat insulating materials, that is, the heat insulating performance will be improved, and in this case, the space will be made of expanded polystyrene or the like. Since it is not necessary to fill the insulating resin, the manufacturing cost can be reduced.

[0010] In the heat insulating profile according to claim 2 of the present invention,
With the above-described configuration, convection and heat radiation generated in the space between both the shape members and both the heat insulating materials are interrupted by the two projections. In the case where it is shifted, the convection and heat radiation generated in the space are cut off at two places, and the heat insulation performance is further improved.

In the heat-insulating profile according to the third aspect of the present invention, since the above-described configuration is employed, for example, if the protrusions of the opposing heat-insulating materials are set to be equal at intervals, the opposing heat-insulating members can be set. Since the heat insulating material having the same cross-sectional shape can be used for both the members, the productivity can be improved, and the heat insulating profile according to claim 4 of the present invention has the above-described configuration. The heat insulation performance is further improved by the amount that the portions overlap in the indoor and outdoor directions.
