Abstract: A mop head unit that can be used for cleaning multiple surface types. The mop head unit is disposable and incorporates a mop head frame with a plurality of inflatable air chambers and a cleaning pad/wipe. The mop head frame and the cleaning pad/wipe are incorporated into a single mop head unit. The mop head unit may be used wet or dry.

Abstract: A scale and cover comprises an electronic scale comprising a scale tray and a user control and a first alignment mechanism. A cover for removably receives the electronic scale where the cover defines an aperture communicating the exterior of the cover with the electronic scale. The cover comprises a second alignment mechanism that engages the first alignment mechanism. A tray comprises a leg that is inserted through the aperture and is supported by the scale tray.

Abstract: The cart of the invention utilizes a sliding support to mount a container onto the cart. In one embodiment the container is a linen bag mounted to the cart handles. A shelf or platform is located below the sliding support. The sliding support allows the container to be stored either under the support and over the platform, or if more storage space is required, the sliding support allows the container to slide on the support, providing open space for items to be placed on the platform. The container may also be easily slid off of the cart for removal by the user. The container may be provided with a telescopic handle and wheels for easy transport of the container and its contents.

Abstract: The maintenance cart includes a cart comprising a primary section, a secondary section, and/or a connection mechanism. The primary section may include a body portion including a plurality of storage, a folding shelf attached to an end of the body portion, and a releasably connectable handle mechanism. The secondary section may includes a mop bucket supporting region and a plurality of rolling members. The connection mechanism if for releasably connecting the secondary section to an end of the primary section.

Abstract: A mop bucket system includes a liquid-retaining portion and an energy-dissipation device. The liquid-retaining portion is configured to retain liquid. It has a bottom wall portion, a first sidewall portion, a second sidewall portion facing the first sidewall portion, a third sidewall portion, and a fourth sidewall portion facing the third sidewall portion. The liquid-retaining portion permits retained liquid to move in a liquid-movement direction extending from the first sidewall portion toward the second sidewall portion within a higher-momentum region having a width that is approximately 70% of a distance between the third sidewall portion and the fourth sidewall portion. The energy-dissipation device is disposed within the liquid-retaining portion and extends into the higher-momentum region.

Abstract: A safety device, comprising at least one sensor for sensing the presence of an object and a warning system that emits at least one precreated verbal warning message after the sensor senses an object. The warning system includes a control system that allows a user to select at least one of a plurality of precreated verbal warning messages for emission. In another embodiment, a safety device comprises a safety cone, a sensor disposed on the safety cone and that senses an object, and a warning system disposed at the top of the safety cone and that emits at least one warning signal after the sensor senses an object.

Abstract: A barricade contains at least one extendable beam. The beams are movable between a non-extended position in which they substantially rest within the footprint of a barricade frame and an extended position in which they extend away from the barricade frame. The beams may contain connecting mechanism which enable the beams of like barricades to be connected, thereby creating a longer barricade.

Abstract: A waste container assembly has a shell with a contiguous shell side wall. The side wall defines an open bottom, an open shell top, and a shell interior defined within the shell side wall. A substantially rigid insert has a closed bottom, an open insert top, and a contiguous insert side wall. The closed bottom and the insert side wall together define an interior for refuse collection. The insert is received substantially within the shell interior with the open insert top accessible through the open shell top. A cover has a top panel, a skirt depending from a perimeter of the top panel, and a refuse opening. The skirt is adapted to overlie a portion of an upper end of the contiguous shell wall when installed.
