Abstract

An acoustical seal for the corners of an enclosure comprising a pair of structural members such as a cover 10 and side panel 11 of a housing for a mechanism comprises an angle corner bulb seal 12 interfitted with straight side seals 13 and 14. Corner seal 12 consists of a relatively corner seal 12 are provided with flared ends to allow insertion of the bulb portion of the ends of side seals 13 and 14. Also, the slot 15 in channel section 16 is widened to receive the ends of the channel sections 17 of side seals 13 and 14. Side flanges 18 from cover 10 are inserted in the slot through the joint to maintain a tight fit at the joint. The corner seal 13 has a very thin wall bulb portion so that the joint contact with frame member 11 is very close to prevent or minimize any leakage space.

An acoustical seal for the corners of an enclosure comprising a pair of structural members such as a cover 10 and side panel 11 of a housing for a mechanism comprises an angle corner bulb seal 12 interfitted with straight side seals 13 and 14. Corner seal 12 consists of a relatively corner seal 12 are provided with flared ends to allow insertion of the bulb portion of the ends of side seals 13 and 14. Also, the slot 15 in channel section 16 is widened to receive the ends of the channel sections 17 of side seals 13 and 14. Side flanges 18 from cover 10 are inserted in the slot through the joint to maintain a tight fit at the joint. The corner seal 13 has a very thin wall bulb portion so that the joint contact with frame member 11 is very close to prevent or minimize any leakage space.

This configuration provides good sealing at corners to eliminate noise leakage.
