A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The first material may have a wicking barrier that inhibits wicking when the bag assembly becomes wet. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank and, together with the wicking barrier and a properly chosen first material, enhances performance of the vacuum bag assembly when wet.Type: GrantFiled: March 28, 2019Date of Patent: May 25, 2021Assignee: SHOP VAC CORPORATIONInventors: James P.

Patent number: 10292551Abstract: A switch assembly for a wet/dry vacuum cleaner is disclosed. The switch assembly includes a switch movable by a user between an ON position and an OFF position. An automatic shutoff assembly is operable in conjunction with the switch assembly to turn the switch to the OFF position in the event that a level of liquid within a tank of the wet/dry vacuum cleaner rises above a predetermined level. When triggered, the automatic shutoff assembly exerts a biasing force urging the switch toward the OFF position. A user can manually override the automatic shutoff assembly by providing a force sufficient to overcome the biasing force.Type: GrantFiled: February 16, 2017Date of Patent: May 21, 2019Assignee: SHOP VAC CORPORATIONInventors: Craig A. Seasholtz, Robert Lent Crevling, Jr., Randy L. Buss, Kevin D. Fry

Patent number: 9167942Abstract: A new vacuum cleaner has a removable rack that combines both tool storage elements and hose fence elements in a compact arrangement. The rack is snapped in place. Laterally-spaced fence elements help hold the hose against the main body of the vacuum cleaner, and hooked upper ends help to retain the hose in place. The outer surfaces of the fence element have adjacent concave outer surfaces that form parts of two separate tool storage elements. One of the retainers has opposed ends that form a clip that can hold a vacuum hose accessory in place. The other retainer has a lower lateral end that extends radially outwardly to an upwardly projecting stem section. The stem section is sized to fit within an interior portion of a vacuum hose accessory.Type: GrantFiled: July 29, 2014Date of Patent: October 27, 2015Assignee: SHOP VAC CORPORATIONInventors: Craig A. Seasholtz, Robert Lent Crevling, Jr.

Patent number: 8689396Abstract: Mating connectors enable a vacuum cleaner section to be releasably attached to a toolbox section. The connectors include a downward-facing tongue that fits in a corresponding horizontal slot. The tongue has a vertical slot that corresponds with a vertical flange adjacent the slot. An interacting tab and slot prevent the vacuum cleaner section from being removed from the toolbox section when a closeable top on the toolbox section is closed. The two sections attach in a position in which upright side walls on the vacuum cleaner section align with the upright sides on the toolbox section, and an extended horizontal work surface is formed by portions of the hinged top on the toolbox section and the vacuum cleaner section. A handle on the vacuum cleaner section can form part of the horizontal work surface, which has parallel lateral grooves with co-linear segments on opposite sides of a recessed channel.Type: GrantFiled: July 7, 2011Date of Patent: April 8, 2014Assignee: Shop Vac CorporationInventors: Melvin E.
