Abstract: A utility cart has four corner posts arranged in rectangular pattern and at least one lower shelf including a recess in the push side edge and a top shelf that, instead of the recess, includes a handle. The other three sides of each of the shelves are substantially the same size and extend beyond the corner posts. The bottom of each of the shelves may include a wagon wheel structure in each corner which secures and supports the corner posts of the cart.

Abstract: An anti-corrosion support device includes a post and a post protector that is disposed about a bottom portion of the post. An interior surface of the post protector is sized and shaped to fit tightly over an exterior surface of the bottom portion of the post. The anti-corrosion support device also may include an adjustment foot that passes through an aperture formed through a bottom portion of the post protector into an attachment member mounted to the post. An anti-corrosion support system includes several of the anti-corrosion support devices, shelf supporting means, and one or more shelves.

Abstract: A mobile refrigeration cabinet that includes a refrigerated section, a non-refrigerated section that has an aperture in a side thereof, and an opening between the refrigerated and non-refrigerated section. The aperture allows access to the non-refrigerated section. The cabinet may include a movable tray disposed in the non-refrigerated section that is movable through the aperture, and a refrigeration system removably mounted on the movable tray. A biasing system is configured to engage the movable tray so as to bias the refrigeration system towards the opening between the refrigerated section and the non-refrigerated section such that a portion of the refrigeration system sealingly engages the opening.

Abstract: A utility cart includes a sensor or plurality of sensors to determine the state of a cart and secure cart contents. A sensor may be used to determine whether the contents of the cart have been accessed. When the sensor determines that the cart has been accessed, an alarm sequence that sounds an alarm or activates a visual indicator will be initiated. The alarm sequence may be terminated by a kill switch or by using an input device to deactivate the alarm. After the cart is used, the cart is re-stocked and the alarm controller is re-armed to return the cart's alarm system to an access sensing state.

Abstract: A utility cart includes an auxiliary swivel caster wheel assembly, a locking mechanism, and a trigger mechanism for causing the locking mechanism to releasably lock the auxiliary swivel caster wheel assembly. The auxiliary swivel caster wheel assembly is unlocked to enable the auxiliary swivel caster wheel to rotate about a vertical axis for improved maneuverability in small areas, and is locked to hold the auxiliary swivel caster wheel in a predetermined position for improved steering as the cart is moved from one location to another. The trigger mechanism is disposed on a steering handle to enable dynamic actuation of the locking mechanism while the cart is in motion.

Abstract: A lock mechanism for manually or automatically fixing a slide bar in either of two positions. A lock body has a key barrel adapted to rotate a lock cam in a first rotational direction. A latch is biased in a closed position, the latch being adapted to move to an open position when the lock cam is rotated in the first rotational direction. A slide bar is fixable in a locked position and an unlocked position, wherein the slide bar is biased in the unlocked position. A knob slider is adapted to move the slide bar into the locked position such that the latch moves to the closed position and engages a notch of the slide bar to fix the slide bar in the locked position. A servo motor is adapted to rotate a servo cam in a second rotational direction to move the slide bar into the locked position, and is adapted to rotate the lock cam in the first rotational direction to move the slide bar into the unlocked position.

Abstract: An emergency crash cart includes a sealing structure that enables multiple storage sections of the cart to be locked and sealed simultaneously. The locking structure enables one of the storage sections to be unlocked and unsealed without unlocking or unsealing the other storage sections. The locking structure also can be actuated to unlock and unseal all storage sections simultaneously for rapid access to the contents of all storage sections of the cart.

Abstract: A mobile heated cabinet and method of mitigating stratification of temperature within the interior of the mobile heated cabinet are disclosed, wherein the mobile heated cabinet can be used to both (a) store food at a stationary location and (b) store and transport food when moved from the stationary location. The disclosed mobile heated cabinet and method mitigate stratification of temperature by providing a heating device, an air circulating device, an external power source, and a self-contained power source.

Abstract: A banquet cart including a cabinet, a plurality of chimneys, an information center, and releasably lockable swivel casters. The plurality of chimneys are positioned inside the cabinet at different corners of the cabinet. The information center includes at least two of (a) a thermometer display indicating the temperature inside of the cabinet; (b) a display indicating time information from a programmable timer; and (c) an information board for displaying text. The releasably locking swivel casters are unlocked to allow swivel action of the casters when a user actuates a foot-operable lever at the front of the cabinet, and are locked when the user releases the lever and the casters are rotated to a predetermined position.
