Description
- This invention relates generally to a mobile sink assembly. More specifically, the present invention relates to a portable or mobile sink assembly utilizing injection molded plastic structural panels having integrally formed connectors. The sink assembly is capable of being packaged and shipped in a knock-down state and assembled into a secure and decorative sink and enclosure assembly without additional fasteners.
- Portable or mobile sinks are very convenient for use wherever access to a water supply and drain facilities are not readily available. Portable sinks have been used in the past to facilitate the preparation of food outdoors and to provide washing and cleaning facilities for patients in nursing homes and hospitals who do not have ready access to conventional washing facilities. It is also very beneficial if there is an area adjacent the sink that can be used to store items related to the washing or cleaning to be done in the sink.

The unit includes a fresh water reservoir, a gray water reservoir, a faucet assembly including a control valve, and a soap dispenser. The majority of the space in the sink enclosure is occupied by the fresh water tank and the gray water tank. Any items to be stored must be kept on the top surface of the enclosure. This area is very small as can be seen in the drawings. The enclosure cabinet is formed from an open frame which is overlaid with a sheet material. This type of structure is not subject to being knocked down for shipment and assembly by the consumer at their location.
- U.S. Pat. No. 6,349,715 discloses another type of mobile sink. This sink is used in conjunction with a mobile cooking device. A water supply is connected to the lower portion of the device to supply water to the faucet adjacent the sink. The used water from the sink drains away from the device through an outlet hose. The device comprises a housing formed of front, back, side top and bottom walls which are permanently attached. This construction is also not subject to being knocked down for shipment and assembly by the consumer.
- Another type of portable sink is disclosed in U.S. Pat. No. 6,836,910. This sink is connected to a water supply to provide water for the sink. The drain empties onto the surface on which the sink is placed. This can lead to a messy and unhealthy situation. The sink enclosure has a drawer for storage but this does not provide a large amount of storage space.
- The present invention provides a portable or mobile sink assembly formed from a plurality of injection molded plastic panels having integrated connectors. The panels and other components are capable of being packaged and shipped in a knock-down state and constructed to form an aesthetically pleasing sink and enclosure. The integrated connection of the side wall panels, back wall panel, front wall panel, bottom panel and sink components simplifies the construction of the sink assembly. The panels are formed from injection molded plastic so as to interlock with one another without the need for separate fasteners or connectors. This assembly incorporates a minimum number of components by integrally forming the connectors into the injection molded panels. The panels are then snapped together to complete the assembly.
