Double groove sliding window made of synthesized resin

Abstract

The invention aims to provide a synthetic resin double groove sliding window with good decoration and a combined supporting part which achieves enough air-tightness and excellent heat-shielding performance using a metal smoke stopping component. In the invention, the enough air-tightness of the combined supporting part can be obtained by fixing a metal indoors side smoke stopping component 40 on the outdoors side surface 23a of synthetic resin combined supporting frame 23 of the inner sash 2 and fixing a metal outdoors side smoke stopping component 50 on the indoors side surface 33a of synthetic resin combined supporting frame 33 of the outer sash 3; an extruding piece (26) disposed on the combined supporting frame 23 extending towards outdoors side comparing to its outdoors side surface 23a can reduce the contact of the indoors air and the indoors side smoke stopping component 40, which is hardly seen from indoors; an extruding piece 36 disposed on the combined supporting frame 23 extending towards indoors side comparing to its in doors side surface 23a can reduce the contact of the outdoors air and the outdoors side smoke stopping component 50, which is hardly seen from outdoors. The combined supporting part achieves excellent heat-shielding performance and good decoration performance.

Description

technical field [0001] The present invention relates to a synthetic resin double-slot sliding window, which combines an inner partition and an outer partition made of synthetic resin with a frame body made of synthetic resin in a push-pull manner. Background technique [0002] Conventionally, various synthetic resin double-slot sliding windows have been proposed in which an inner partition and an outer partition made of synthetic resin are slidingly combined with double grooves on the indoor side and the outdoor side of a synthetic resin frame body. [0003] On the other hand, although in the double-slot sliding window made of aluminum, the smoke blocking sheet is integrally arranged on the closing frame of the inner partition and the outer partition to improve the airtightness of the closing part, etc., but in the above-mentioned In the synthetic resin double-slot sliding window, since the hinged frame is made of synthetic resin, the smoke blocking sheet is also made of syn...

Problems solved by technology

[0008] In addition, since the smoke-blocking parts fixed on the closing frame of the inner partition are exposed indoors and are in direct contact with the indoor air, the heat in the room is easily transferred to the smoke-blocking parts.

[0009] Therefore, the heat of the outdoor air or the heat of the indoor air is transferred to the metal smoke-blocking member, and is easily transferred to the indoor air or the outdoor air, and the heat insulation performance of the joint portion deteriorates.

[0010] Therefore, it is not good as a synthetic resin double-slot sliding window for the purpose of insulating indoors and outdoors and making it difficult to transfer heat.

[0011] In addition, since the metal smoke blocker is adjacent to the synthetic resin hinged frame and can be seen from the outside and indoors, it does not fit well, and the decoration of the hinged portion is poor.
