Abstract: A portable restroom includes an enclosed interior including a door, a waste tank, a commode disposed within the enclosed interior and coupled to the waste tank, a power source, a microprocessor coupled to the power source, a door sensor positioned to sense whether the door is open or closed, and a door lock sensor positioned to sense whether the door is locked or unlocked. Sensors can be provided to sense the closed status of the door and the status of the door lock. Additional sensors can monitor various levels and usage of consumables. The microprocessor monitors the sensed data and wirelessly alerts a service provider when the restroom needs service. A payment receiving means can be provided to the portable restroom and coupled to the microprocessor so that a user can provide payment for access to the portable restroom.

Abstract: A portable restroom includes an automatic continuous flushing feature and a touchless flush request sensor. An automatic light provides welcome lighting in darker locations. An electric fan increases ventilation and reduces odor and temperature in the restroom. Sensors monitor various levels and usage of consumables. A processor monitors the sensed data and wirelessly alerts a service provider when the restroom needs service. A flushing bowl is placed in the commode opening to hide the waste within the tank. The flushing bowl includes a relatively small opening in a forward portion of the inner bowl surface for waste to pass through. A spray nozzle for directing water over the interior of the bowl is provided to minimize the chance that waste sticks to the inner bowl.

Abstract: A portable restroom is designed to provide features which enhance the comfort and appeal to users. These features include a rigid and stable structure, including a rigid floor structure, thus providing a sense of security to the user. Further, flushing and fresh water capabilities are achieved by using a dual tank structure made capable by the base design itself. This dual tank structure is achieved utilizing a unique siphoning pump to provide appropriate functionality.

Abstract: In order to provide additional flexibility in a portable restroom, a base assembly is specifically designed to include an internal tank capable of maintaining and carrying flushing fluid. Thus, when a flushing restroom is desired, an additional tank is not needed. In order to convert to a flushing model, the base assembly is simply filled with appropriate liquid, and a pump is added. In addition to providing additional capabilities, the additional fluid in the base unit provides for more weight, thus increasing the stability. Also, the base assembly has a support structure which can be snap fit to the tank member. By allowing the snap fitting feature, the support structure can be designed very rugged, however will very easily and completely attach to the tank member.

Abstract: A suspension arm mounting assembly for mounting a single or a pair of suspension arm assemblies to an actuator arm. The mounting assembly includes spaced finger projections extending from a base plate member of the suspension arm which extend through a hole in the actuator arm and include shoulder portions for snapping to and being secured against the opposite surface of the actuator arm.

Abstract: A hand-held power driven cultivator incorporating a pair of ground working implements or tillers mounted on a pair of laterally spaced vertical shafts depending from a motor and drive train enclosing housing. The tillers are counter-rotated and include interdigitating tines which engage and move the earth forwardly. A barrier freely surrounds each tiller supporting and driving shaft, and completely encloses the shaft between the tiller and the overlying housing. A scraper blade is associated with each barrier and includes a scraping edge spaced slightly from the barrier so as to enhance the ability of the barrier to repel or prevent the accumulation of weeds, roots, debris, and the like. Support and manipulation of the housing is provided for by an elongated handle including an upper fixed hand grip and power switch, and a lower adjustable hand grip.
