Document Type and Number:
Japanese Patent JP2015083747
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sound insulation structure of a soundproof door capable of eliminating inconvenience in use caused by providing a door stop.SOLUTION: A soundproof door 1 comprises a door frame 3 and a door panel 5. Two rubber members 7 are attached in two rows to a lower side surface 5a of the door panel 5, while two rows of recessed parts 34 are formed on a surface of the opposed door frames 3. When the door panel 5 is closed to the door frame 3, the rubber members 7 are placed on a tapered part, and move toward the rear side while being elastically deformed, and the tip ends of the rubber members 7 are fitted to the recessed parts 34 to close a clearance formed between the door panel 5 and the door frame 3. Thus, the soundproof door 1 can insulate sound so that the sound generated in a soundproof chamber does not leak to an external part. This soundproof door 1 can also eliminate a danger when a user makes a false step on the door stop since the door stop is not provided on the lower side of the door frame 3.
