Durable filter cage for air-moving system
First Claim
Patent Images
1. An air-moving system coupled with a filter, comprising:
- a cage adapted to be fixedly coupled to a vacuum intake portion of the air-moving system, the cage having a longitudinal axis and comprising;
one or more longitudinally angled ribs disposed at an angle greater than zero degrees and less than 90 degrees to the longitudinal axis and spaced a distance from the longitudinal axis about a perimeter of the cage.

Abstract
The disclosure provides a system having a cage mounted in an air-moving system, such as a wet and dry vacuum cleaner, which provides energy-absorbing structural ribbing for a more robust cage. The energy-absorbing ribs can tolerate impacts better than the relatively stiff, axial ribs aligned in a longitudinal direction of the cage found in prior efforts. The energy-absorbing ribs are formed in a non-aligned direction to the longitudinal axis, that is, at some non-zero angle to the axis. Circumferential ribs can be formed at some angle to the energy-absorbing ribs.
