DEVICE FOR AT LEAST PARTIALLY BLOCKING AN OPENING AND FORMING A SEAL IN THE OPENING

摘要

A device for at least partially blocking an opening includes a first body, a second body rotatably mounted to the first body and a compressible seal extending from the first body. The seal includes a first portion, a plate having a hole at one end of the first portion, and a second portion extending away from the plate. A hollow shaft extends from the second body and through the first body, the first portion, the hole in the plate, and into the second portion. The shaft has a shoulder in the second portion that is wider than the hole in the plate, and moving the shaft relative to the first body compresses the second body until the shoulder reaches the plate and then compresses the first body. Such compression expands the first and/or second portions and presses them against the inside of the opening to form a seal.

主权项

1. An adapter configured to be mounted in an opening to form a seal with an interior wall of the opening, the adapter comprising:
a first body; a second body rotatably mounted to the first body; a compressible seal extending from the first body, the compressible seal including a compressible seal first portion, the compressible seal first portion having a first end at the first body, a second end and an interior, the compressible seal further including a plate having a hole at the second end of the compressible seal first portion, and a compressible seal second portion having a first end at the plate and a second end and having an interior, and a hollow shaft operably connected to the second body and having a longitudinal axis and a shaft first end at the second body and a shaft second end, the shaft projecting through a passage in the first body, through the interior of the first portion of the compressible seal, through the hole in the plate, and into the interior of the second portion of the compressible seal, the shaft having a shoulder in the interior of the second portion of the compressible seal, the shoulder being spaced from the plate and spaced from the second end, and a width of the shaft at the shoulder being greater than a width of the hole in the plate.
