Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hermetic thermal insulation structure for a door for a door,

The present invention relates to a door hermetic thermal insulation structure for a door and a manufacturing method thereof, and more particularly, to a door hermetic thermal insulation structure for a door and a method of manufacturing the same.

In the case of a window or a door used in a building, it is generally designed by a sliding door or a hinged door, and even when a door or a window is closed, a gap is formed and the door is not completely closed. Therefore, Is used.

The windshield device for a window or a door is generally used for a windshield, a soundproofing, a moisture proofing, a buffering, etc. attached to a window, a window frame or an insect screen frame or the like. In the groove formed in the base band of the synthetic resin base, Has been formed and used in a structure in which airtight means excellent in durability, corrosion resistance, and the like are fixed by ultrasonic waves, strong adhesives, etc., relatively excellent in elasticity and restoring force.

The airtight means used in the conventional windshield device having such a configuration is generally formed in a vertical state, that is, when the window is closed, the front end of the airtight means of the windshield device attached to the groove of the window frame frame, The pressure is applied directly to the tip of the cut airtight means such as mohair, monofilament yarn and nonwoven fabric by being pressed on the frame, so that the airtightness of the various strands is bent in various directions and the functions of wind, soundproofing, Respectively.

Korean Unexamined Patent Publication No. 10-2006-0028093 (published on Mar. 29, 2006) discloses that a hermetic member fixed to a groove of a base band is inclined within a predetermined angle, and the strands of the hermetic member are alternately staggered, In a known windshield member having a base band having a hermetic member fixing groove at the center of the plane and a plurality of airtight sealing members fixed to the hermetic member fixing groove, The groove is tilted to one side from the front side of the base band, the hermetic member is fixed to the hermetic member fixing groove so as to be inclined at a predetermined angle, and the hermetic member is inclined so that the strands are alternately staggered. According to the disclosed technology, even if the hermetic member is pressed against the window for a long time, the hermetic member is excellent in the restoring force and the hermetic effect is excellent, and each strand of the hermetic member is alternately crossed so that the elastic force is increased and no gap is formed in the hermetic member. , Soundproofing, moisture-proofing, buffering and the like, and can significantly extend the service life of the windshield member.

The Korean Patent No. 10-0818322 (registered on Mar. 25, 2008) is very simple to manufacture, and can easily improve the production capacity, and has excellent elastic restoring force, thereby improving the airtightness function. And the elastic member cover is put on the elastic member, so that the contamination by the foreign substance can be reduced and the life of the wind guard member itself can be prolonged. According to the disclosed technology, an elastic member cover body constituting a base sheet and a synthetic resin sheet covering the upper surface of the base band constituting the windshield member and having an elastic member integrally formed with the base band at the central portion of the base band .

Conventional windshield systems for windows or doors as described above generally use mohair as a hermetic means. Such a mohair has a disadvantage that the window is closed for a long time and the mohair is pressed for a long time or exposed to sunlight or rainwater for a long time, the elasticity is lowered and the restoring force is greatly decreased and the airtightness is also deteriorated.

In addition, the conventional windshield device for a window or a door has disadvantages in that, when the airtight means can not perform windshielding or the like due to corrosion or the like, it needs to separate not only the airtight means but also the base band supporting the airtight means.

In the conventional windshield device for a window or a door, if the mohair used as a hermetic means is exposed to sunlight or rainwater for a long time and corroded, the windshield easily breaks into a powdery form, and the corroded mohair flows into the room, Inhalation may cause diseases such as respiratory diseases.
