Abstract
An adjustable duct connector includes a base plate, a ring arm slidably coupled to the base plate, and a handle rotatably coupled to the base plate and the ring arm. Rotation of the handle selectively transitions the ring arm between a first position proximate the handle and a second position arranged further from the handle.
Claims20
An adjustable duct connector, comprising:
- a base plate;
- a plurality of ring arms movably coupled to the base plate;
- and
- a handle rotatably coupled to the base plate and to each of the plurality of ring arms through a linkage so that rotation of the handle displaces each of the plurality of ring arms between retracted position and an extended position.
1 more element
An air heater, comprising:
- an air inlet;
- an air outlet;
- a heating device configured to heat air flowing between the air inlet and the air outlet;
- and
- an adjustable duct connector coupled to at least one of the air inlet or the air outlet, the adjustable duct connector comprising:
- a base plate;
- a ring arm slidably coupled to the base plate;
- a handle rotatably coupled to the base plate and the ring arm, wherein rotation of the handle selectively transitions the ring arm between a first position proximate the handle and a second position arranged further from the handle;
- and
- a locking mechanism configured to secure the ring arm in the first position or the second position.

An air heater, comprising:
- an air inlet;
- an air outlet;
- a heating device configured to heat air flowing between the air inlet and the air outlet;
- and
- an adjustable duct connector fixedly coupled to at least one of the air inlet or the air outlet, the adjustable duct connector comprising:
- a base plate including a center portion and a plurality of plate arms extending radially outwardly from the center portion;
- a plurality of ring arms, each being movably coupled to a respective one of the plurality of plate arms;
- and
- a handle rotatably coupled to the center portion and each of the plurality of ring arms, so that each of the plurality of ring arms translates along the respective one of the plurality of plate arms, in response to selective rotation of the handle, between a first position where an outer periphery of the plurality of ring arms defines a first diameter and a second position where the outer periphery of the plurality of ring arms defines a second diameter, wherein the second diameter is greater than the first diameter.
