Portable Dual-Sink Hand-Washing Station

Abstract

A portable dual-sink hand-washing station which includes a base supporting a sink structure thereabove, the sink structure defining an upper surface area, and a station top supported above the sink structure and having a vertical support structure defining a diagonal divide of the upper surface into two sections, each section having a sink opening with a rear edge along the vertical support structure such that each sink opening has a larger end and a smaller end, whereby each larger end provides increased clearance for hand-scrubbing. At least one of the sink openings has an increased maximum length to accommodate forearm-scrubbing. Various embodiments with preferred features are also disclosed.

1 . A portable dual-sink hand-washing station comprising:
 a base supporting a sink structure thereabove, the sink structure defining a substantially-horizontal upper surface area;   a station top supported above the sink structure and including vertical support structure defining a diagonal divide of the upper surface area into two sections; and   each section having a sink opening with a rear edge along the vertical support structure such that each sink opening has a larger end and a smaller end,   whereby each larger end provides increased clearance for hand-scrubbing.   
     
     
         2 . The portable dual-sink hand-washing station of  claim 1  wherein at least one of the sink openings has an increased maximum length to accommodate forearm-scrubbing. 
     
     
         3 . The portable dual-sink hand-washing station of  claim 1  wherein at least one sink opening is quadrilateral in shape. 
     
     
         4 . The portable dual-sink hand-washing station of  claim 1  wherein the sections are quadrilateral sections each having at least one pair of opposite sides of unequal length. 
     
     
         5 . The portable dual-sink hand-washing station of  claim 4  wherein at least one sink opening is quadrilateral in shape. 
     
     
         6 . The portable dual-sink hand-washing station of  claim 1  wherein the station top includes one or more hang-members configured to hold user accessories. 
     
     
         7 . The portable dual-sink hand-washing station of  claim 6  wherein the station top includes one or more vertical post structures each at an opposite end of the diagonal vertical support structure, each post structure having a post distal end which forms one of the hang-members. 
     
     
         8 . The portable dual-sink hand-washing station of  claim 7  wherein the hang-member(s) is/are integrally-formed with the vertical support structure. 
     
     
         9 . The portable dual-sink hand-washing station of  claim 1  further including:
 a grey-water storage tank positioned in the base, the tank receiving grey water draining from the sinks; 
 a suction tube extending from an inlet end thereof within the grey-water storage tank upwardly and from there downwardly to an outlet end thereof at a bottom portion of the base; and 
 a check valve in the suction tube, the check valve having a cracking pressure sufficient to prevent flow from the grey-water storage tank through the suction tube without application of suction at the outlet to overcome the cracking pressure. 
 
     
     
         10 . The portable dual-sink hand-washing station of  claim 9  wherein the check valve is at the inlet end. 
     
     
         11 . The portable dual-sink hand-washing station of  claim 9  wherein the check valve is positioned outside the grey-water storage tank. 
     
     
         12 . The portable dual-sink hand-washing station of  claim 9  wherein the suction tube has a highest point positioned above a highest level of grey-water storage. 
     
     
         13 . The portable dual-sink hand-washing station of  claim 12  wherein the check valve is positioned in the tube above the highest level of grey-water storage. 
     
     
         14 . The portable dual-sink hand-washing station of  claim 1  further including an outlet valve at the outlet end of the suction tube. 
     
     
         15 . The portable dual-sink hand-washing station of  claim 1  wherein the base further includes four handles spaced around the base. 
     
     
         16 . The portable dual-sink hand-washing station of  claim 1  further including a fresh-water tank and for each sink a spigot above the sink and a foot-pedal-actuated pump unit for user actuation of fresh-water flow, wherein:
 the base has a main upper structure and a ground-engaging lower structure, the pedal-actuated pump units being attached to the lower structure; and 
 each pump unit has a plurality of attachments to the lower structure, one or more of which are fastener-free, 
 thereby facilitating pump-unit installation and removal. 
 
     
     
         17 . The portable dual-sink hand-washing station of  claim 16  wherein the fastener-free attachments each engage a complementary receptor on the lower structure. 
     
     
         18 . The portable dual-sink hand-washing station of  claim 17  wherein each fastener-free attachment is a tab on a pump unit and each complementary receptor is a tab-receiving pocket on the lower structure.
