Title:
DOOR GAP BLOCKING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/204524
Kind Code:
A1
Abstract:
The present invention is to provide a door gap blocking apparatus for windproof or dustproof, which is operated by an electrical sensor and an electromagnet to block a gap in a door that is manufactured by using reinforced glass or other materials, so as to improve cooling/heating efficiency and shield contaminants such as dust. The door gap blocking apparatus may comprise: an attachment plate (100) which is fixed to the lower end of a reinforced door (10) that is the entrance and is formed of a magnet or metal to which a magnet can be attached; a sensor (200) which senses opening or closing of the reinforced door (10); and a blocking module (300) which drives the electromagnet, when the sensor (200) senses the closing, so that an electromagnetic plate (320) sliding in up and down directions by the electromagnetic force is attached to the attachment plate (100) to block the gap in the entrance.
