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.

Claims

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.

3. The system of claim 1, wherein an inner surface of the longitudinally angled ribs extends radially inward relative to an inner surface ofthe circumferential ribs.

4. The system of claim 1, wherein an outer surface of the longitudinally angled ribs extends radially outward relative to an outer surface of the circumferential ribs.

5. The system of claim 1, further comprising:

a mounting assembly to which the cage is coupled;

a filter having a filter element and a seal coupled to the mounting assembly, the cage, or a combination thereof; and

a drum coupled to the mounting assembly.

6. The system of claim 5, wherein the filter comprises a lateral seal portion coupled to the filter element, the filter being removably coupled around at least a portion of the cage, and the lateral seal portion being oriented radially inward toward the longitudinal axis, the lateral seal portion at least partially extending into an undercut area formed in the mounting assembly, the cage, or a combination thereof, the lateral seal portion being adapted to be compressed to seal the filter to the mounting assembly.

7. The system of claim 6, further comprising a filter clamp coupled to the mounting assembly.

2. The system of claim 2, further comprising one or more circumferential ribs disposed at an angle to the longitudinally angled ribs and coupled to the longitudinally angled ribs about the cage perimeter.

8. An air-moving system, comprising:

a mounting assembly of the air-moving system;

a cage adapted to be fixedly coupled to the mounting assembly adjacent a vacuum intake on the 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; and

one or more circumferential ribs disposed at an angle to the longitudinally angled ribs and coupled to the longitudinally angled ribs about the cage perimeter.

9. The system of claim 8, wherein an outer surface of the longitudinally angled ribs extends radially outward relative to an outer surface of the circumferential ribs.

10. The system of claim 8, wherein an inner surface of the longitudinally angled ribs extends radially inward relative to an inner surface of the circumferential ribs.

11. The system of claim 10, wherein an outer surface of the longitudinally angled ribs extends radially outward relative to an outer surface of the circumferential ribs.

12. The system of claim 8, further comprising a filter having a filter element and a lateral seal portion coupled to the filter element

13. The system of claim 12, wherein the filter is adapted to be removably coupled around at least a portion of the cage, and the lateral seal portion being oriented radially inward toward a longitudinal axis, the lateral seal portion at least partially extending into an undercut area of the mounting assembly, the cage, or a combination thereof, the lateral seal portion being adapted to be compressed to seal the filter to the mounting assembly.
