STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT




Not applicable.




BACKGROUND OF THE INVENTION




The present invention relates to portable washstands in general, and to washstands which have an associated water supply and water collection housing in particular.




There are many circumstances where it is desirable or necessary to wash one's hands at a location which is far from running water. In the commercial world, construction sites, remote temporary facilities, farms, orchards, and agricultural facilities are all locations where the limited time of the employment or the variability of location may make permanent sanitary facilities impractical or uneconomical. In the provision of entertainment such as at sporting events, fairs, concerts, and special events, there also will be a need to provide facilities for washing hands, sometimes for many thousands of people, but only for a few days a year. In these circumstances the expense of constructing plumbed facilities is simply not justified. The solution widely adopted is the short term installation of portable toilets and washstands. These devices have fresh water and waste receptacles which are enclosed within the unit and do not connect to any outside water supply or sewerage system.




In order to produce a facility which is lightweight and durable, portable washstands have been fabricated of molded plastic. The plastic washstand can be molded in any desired shape, and hence can—with a few parts—provide multiple functions. Moreover, the plastic washstand is not susceptible to rust, requires no painting, and is waterproof. However, in order to extend the period of functionality of a stand-alone washstand it is necessary to provide significant volume for storage of fresh and waste water. Yet the manufacture of large plastic parts can be expensive, both in the design and manufacture of the molds, and in the actual fabrication of the finished parts. Some portable washstands have reduced the total volume required by combining in a single vessel freshwater and wastewater separated by a flexible membrane. Although this design approach is acceptable, it would be desirable to separate freshwater and wastewater as much as possible. Moreover, different applications may require different washstand features. An industrial application may need to be rugged, but may not require ornamentation; a entertainment application may need to resist vandalism, yet have an attractive appearance. Maintaining a variety of different washstands in inventory can add to a distributor's costs.




What is needed is an economical portable washstand which limits the need to manufacture large specialized molded plastic parts, which is durable, and which is configurable to different needs.




SUMMARY OF THE INVENTION




The portable washstand of this invention has a core module or central column which contains the water pumps, spouts, and connecting conduits. The central column is rigid and durable, and has fasteners for releasibly attaching one or more water receptacles. The fasteners may be in the form of flexible bands or straps which form loops which encircle conventional plastic barrels or drums. The loops are clamped to restrain the barrels, allowing them to serve as the receptacles for the freshwater and the soiled or greywater. By fabricating parts which are readily assembled to conventional drums, the receptacle cost is minimized. This is particularly the case when expendable previously used drum shipping containers, of essentially no value, may be used. The central column extends upwardly from a platform which rests on a molded plastic base. In a two station washstand, the central column has two sets of flexible metal straps, an upper and a lower strap extending outwardly on each side of the column. Adjustable fasteners in the central column apply tension to the straps to retain the two drums in an upright orientation. The open tops of the drums are covered by a molded plastic countertop which has formed therein two washbasins. Each washbasin has a water spout and a foot operated pump. The pumps are associated with a water supply tube which extends into one of the drums which constitutes the freshwater receptacle. The wash stations are drained into the other drum which constitutes the waste water receptacle. The two spouts may be formed as integral parts of the stainless steel central column to resist vandalism. For decorative purposes, a molded front panel extends between the countertop and the base, and together with a sheet rear panel encloses the two drums. Paper towel and soap dispensers may be connected to the central column. For a single wash basin assembly, the same central column, although with only one spout, may be connected with a different countertop and base, with the single drum having a membrane dividing fresh water from waste water. In a similar fashion other assemblies may be constituted employing one or more common parts. For example, the decorative skirt may be omitted in industrial and agricultural applications.




It is an object of the present invention to provide a washstand which can be assembled from modular components about a central core module to permit economical modification of the washstand to suit different needs.




It is an additional object of the present invention to provide a low cost portable washstand which incorporates conventional plastic drums as water containers.




It is another object of the present invention to provide a washstand which is economically transported and may be assembled with locally available parts.




It is also an object of the present invention to provide a portable wash station which is readily modified in its appearance to suit different occasions.




It is a further object of the present invention to provide a sturdy portable washstand which is readily supplied with preloaded containers of water.




It is yet another object of the present invention to provide a washstand which is readily disassembled into component parts for compact shipping to and from the site of use.




Further objects, features and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring more particularly to

FIGS. 1-6

, wherein like numbers refer to similar parts, a portable washstand


20


of this invention is shown in FIG.


1


. The washstand


20


has a core module


86


with a central column


22


, preferably formed of stainless steel, to which two drums


24


are clasped. The drums may be formed to a variety of configurations. In a particularly low cost example, conventional molded plastic cylindrical barrels or drums may be used. Another option would be to employ conventional trash receptacles. The column


22


and the drums


24


rest on a molded plastic base


26


which may have two circular rims


28


defining the outer perimeter of the drums. The column


22


has a rectangular foot


30


which extends outwardly and to which two foot operated pumps


32


are mounted. The foot


30


extends partially beneath the drums


24


, thereby contributing to the stability of the upright column


22


. The foot


30


preferably has an upwardly protruding flange or hook


80


which extends frontwardly of the drums


24


. A tie-down strap, not shown, may then be used to restrain the washstand


20


against tipping when it is mounted within a truck, by applying the strap over the foot


30


, and tightening it.




An upper band


34


and a lower band


36


for each drum extend on either side of the column


22


forming coaxial loops within which the drums


24


are received. The bands may be continuous through openings in the column, or, as shown, the bands may have right angle bent segments at each end which have holes which receive fasteners


38


therethrough. The fasteners


38


extend through holes


44


in the column


22


. Tightening the fasteners


38


causes the bands to be clamped tightly around the drums


24


to hold them in place. One drum serves as a freshwater receptacle


40


, while the other drum serves as the wastewater or gray water receptacle


42


.




The bands


34


,


36


permit readily available plastic drums to be used with the washstand


20


without requiring exact tolerances on the manufacture of the drums. Throughout the world, cylindrical drums of a diameter of about 23-24 inches are widely used for the transport of liquids and granular material. This type of drum is not a proprietary product and is manufactured by numerous manufacturers in very large quantities, typically by the process of blow molding. Blow molding is one of the most efficient means of making large hollow parts and is also a speedy process. The volume of these conventional plastic drums is approximately 55 gallons. The drums may be obtained with or without a top. Preferably for use within the washstand


20


drums without a top would be employed, or drums with tops would have the tops removed. Plastic drums are often used for transporting stock materials to end manufacturers, and hence are used by the manufacturer only to receive materials, not to ship finished product. For example a food processor might receive olives, syrups, or oils in plastic drums. Hence manufacturers of plastic drums are located throughout the world, making drums very easy to obtain. In addition, secondhand drums are also readily available. Because the washstand


20


may utilize conventional cylindrical drums it is economically manufactured—it some configurations eliminating the need to manufacture the largest components thereof; and it is also economically shipped overseas, because the largest volume components will be locally obtained. The bands


34


,


36


may be flexible thin metal straps, or they may be braided fabric or fiberglass, or even a flexible rope, or some resilient material. This attachment arrangement allows drums of non-cylindrical or irregular shape to be readily accommodated. The upper and lower bands


34


,


36


need not be of the same size, thus permitting the use of tapered drums. The mechanism illustrated for applying tension to the straps is illustrative, however other tensioning assemblies may be employed.




A molded plastic countertop


46


overlies the two drums


24


and has a downwardly extending skirt


48


which forms a barrier over the joint between the drums and the countertop. The countertop is preferably formed as a unitary molding which incorporates two oval washbasins


50


. The countertop may be formed as a thermoformed thermoplastic part. The countertop


46


has a generally horizontal top wall


52


with the washbasins


50


being concave recesses extending below the top wall. Although each washbasin may be provided with an outlet and a drain which extends into the gray water receptacle


42


, for simplified construction, the washbasin


50


over the gray water receptacle


42


has an outlet


54


at its lowest point which is connected to a drain


56


. The wash water which enters the other washbasin


50


is conducted by a recessed trough


57


which extends from the lowest point of one washbasin into the other washbasin. Thus the washbasin which is connected to the drain


56


will be recessed to a greater extent than the other washbasin. The drain


56


extends into the gray water receptacle


42


.




Two spouts


58


extend upwardly from the column


22


and are bent to face downwardly and to discharge water into a washbasin


50


. The spouts


58


do not have valves or handles associated with them, because water can only be advanced through a spout


58


when a foot pump


32


is operated. The spouts


58


are thus connected to one of the foot pumps


32


by a conduit


88


. The spouts


58


and the conduits


88


may be separate elements housed within the column or, alternatively, the spout may be integrally formed with the central column


22


. The integral assembly has the advantage that the spouts are not removable from the column, and are thus extremely sturdy and resistant to impact. Such sturdiness tends to discourage acts of vandalism directed against the washstand


20


.




A utilities support


62


extends above the countertop


46


and may be welded to the column


22


or otherwise attached to it. The utilities support


62


may have a bracket


64


to which a towel dispenser


66


is attached. The bracket


64


may extend horizontally as shown, or may extend vertically to permit the attachment of conventional towel dispensers which are configured for attachment to a vertical wall. A conventional soap dispenser


68


may be mounted to the utilities support


62


below the towel dispenser


66


. Alternatively, the soap dispenser may be formed integrally with the column


22


.




Water is supplied to the foot pumps


32


by a water intake tube


70


which extends from the column


22


at a level above the freshwater receptacle


40


and which descends into the freshwater receptacle drum to a level adjacent the bottom of the drum. The intake tube


70


is preferably a flexible plastic tube which will not interfere with the removal or installation of the receptacle


40


. A perforated weight


94


, as shown in

FIG. 3

, is preferably attached to the bottom of the water intake tube


70


to maintain the tube inlet at the lowest level within the fresh water receptacle, and to prevent the mouth of the tube becoming blocked by suction attachment to the bottom of a drum.




For cosmetic purposes, and to restrict access to the drums, the volume between the base


26


and the countertop


46


is enclosed by a molded front panel


72


and a rear panel


74


. The front panel


72


and rear panel


74


may be received within a lip


76


protecting upwardly from the base


26


. The front panel


72


is preferably molded in a single sheet thermoforming process and may have decorative indicia


78


molded therein. The decorative indicia


78


may be of a variety of decorations or patterns, allowing different front panels


72


to be attached to the washstand


20


for different occasions. For example, a pastel colored plastic front panel with floral decorations may be employed for use of the washstand at an outdoor wedding, while a gray or black undecorated front panel may be used when the washstand is placed at a construction site. The front panel may be molded in a splayed configuration to eliminate undercut portions in the mold, and then folded to assume the desired configuration. The rear panel which will typically not be visible may be formed of a rectangular extruded and cut sheet of plastic material. The rear panel


74


also may be received within the lip


76


on the base


26


, and extends from the base to the countertop


46


. The upper edges of the front panel


72


and rear panel


74


may be retained between the countertop skirt


48


and the drums


24


.




The countertop may be provided with removable fittings


82


at the rear which permit the waste water to be drained from the grey water drum, and fresh water to be added to the freshwater drum. The fittings may have a simple lock mechanism, not shown, to restrict tampering with the drum contents.




The washstand


20


is formed around a core module


86


, which as shown in

FIG. 3

, includes the central column


22


and the essential plumbing elements of the washstand. Variable practical and ornamental accessories work in conjunction with the core module


86


to provide a washstand


20


for a particular application. In the core module


86


, the central column


22


extends upwardly from the stabilizing foot


30


which supports both the column and the foot pumps


32


. The central column


22


has an interior cavity which receives elements of the washstand plumbing. The core module


86


includes all the core mechanics and plumbing required to unite the receptacles


40


,


42


, with the washbasins


50


. The conduits


88


between the foot pumps


32


and the spouts


58


, the water intake tube


70


and the connections


90


between the intake tube and the foot pumps, and the fastening mechanism for attachment of the receptacles are all united with the central column


22


of the core module


86


.




Although the central column


22


will usually not be the primary structural support for the countertop, it does have mechanical functions. First, it is sufficiently strong to hold the two receptacles together as they are moved. Second, the column


22


will need to have some torsional stiffness, as it will be subjected to impacts such as by collision or dropping which will tend to twist it. In the structure illustrated, the column is a single rectangular channel, with flexible nylon, rubber, or neoprene hoses


88


,


90


which connect the pumps to the spouts, and the water intake tube


70


with the pumps. Alternatively, the column could be formed of three rectangular or cylindrical steel tubes welded together, with one serving as a conduit or store of soap, and one serving as a conduit between a foot pump and each spout. In such an arrangement, several steel brackets are welded to the three conduit tubes to accept the flexible bands for securing the water receptacles.




Because the freshwater receptacle is a drum which is easily separated from the remainder of the washstand, the washstand


20


is readily supplied with fresh water in cases where potable water is not available at the final site, by shipping one or more drums prefilled with approved potable water, and sealing the drum with a removable seal. Many shipping devices such as forklift trucks are already configured for moving loaded drums of this type, so the filled plastic drums are readily moved from place to place with conventional equipment.




The washbasins are accessed by two persons standing in the recess


84


defined between the two adjacent drums, the washbasins being positioned along an axis which is about


30


degrees from the column


22


. The front to back dimension of the washbasin is about 10 inches, and sufficient clearance is provided such that the user may stand at the washbasin, washing his hands and rinsing up to elbow height.




An alternative embodiment washstand


120


may be provided with a countertop


122


which has two molded washbasins


124


and integral attachment surfaces for a paper towel dispenser


66


and two soap dispensers


68


. As shown in

FIG. 2

, the countertop


122


has a frontwardly facing segment


126


extending above the connecting trough


128


between the washbasins


124


. A paper towel dispenser


66


is attachable to the segment


126


. Side segments


130


extend from the frontwardly facing segment


126


which extend above each washbasin. A soap dispenser


68


may be mounted by screws to each side segment


130


. Alternatively, the frontwardly facing segment and the side segments may be configured to permit two paper towel dispensers to be positioned on either side of a single soap dispenser. Fittings


82


seal the entrances


132


to the drums provided adjacent each basin. The spouts will extend through the countertop


122


through openings


134


near each washbasin. As in the countertop discussed above, both washbasins drain through a single drain


136


.




The washstand will typically be provided as a kit of parts for assembly by the end user into a washstand while using locally supplied drums. The design lends itself to modular assembly into different washstand configurations. For example, a single wash basin washstand, for use where space is at a premium, or where usage levels are lower, could be formed with a similar central column, but having only a single spout, and instead of two drums, having only a single drum with a collapsible membrane suspended within the drum to variably define a barrier between fresh water and waste water.




The central column, which is typically the most costly element of the washstand, can be configured with differing accessories to suit particular needs. For example, the decorative front panel


72


may not be attached for units being employed at purely industrial or agricultural sites, thus extending the life of the front panels for use in more consumer-oriented venues such as concerts and fairs. Likewise, the plastic base may be omitted in some situations.




Although cylindrical drums have been illustrated as receptacles for the fresh water and the gray water, it should be noted that rectangular, square, or irregular shaped drums may also be used. Or, alternatively, specially formed drums which have molded elements which snap onto portions of the central column, or onto portions of the opposing drum could also be used. Moreover, a custom drum may be molded with a square mounting flange which would be bolted directly to the central column. For further stiffness in the assembled washstand, the custom molded drum may have a downwardly opening straight channel which overlies a projecting flange formed on the column's metal foot


30


.




Another alternative embodiment washstand


200


is shown in

FIGS. 4-6

. The washstand


200


uses a combination of pin connection and a flexible strap to secure the drums


202


to the central column


204


. The central column


204


is a rearwardly opening U-channel to which two spouts


206


are fixed. As shown in

FIG. 5

, conventional cylindrical drums which serve as a freshwater receptacle


208


and a wastewater receptacle


210


, are provided with cutout openings


212


in the drum rims


214


to provide clearance for the connecting trough


216


of the countertop


218


washbasins


220


. A pin hole


222


is drilled in the drum rim


214


on either side of the opening


212


.




A yoke


224


engages the two drums


202


and connects them to the column


204


. The yoke


224


is a stiff metal member having a center segment


226


which extends between the two drums


202


and which extends parallel to planes tangent to the two drums. The center segment


226


may be a flat barstock piece having a frontward bail opening


228


which projects through a rectangular slot


230


in the front wall


232


column


204


. The bail opening


228


receives the bail of a padlock or other conventional lock.




Two spacer blocks


234


are fixed to the center segment


226


. Each spacer block


234


has a pin


236


which extends from each side of the block and through one of the pin holes


222


. The spacer blocks position the drums


202


the desired distance apart. Once the pins


236


are extended through their respective pin holes


222


, spring clips


238


are inserted through clip holes


240


in the pins


236


on the interior of the drums


202


to fix the yoke


224


to the drums. In order to keep the spring clips


238


associated with the yoke


224


, a wire


242


is looped beneath the two pins


236


which extend from each spacer block


234


and is crimped above the center segment


226


. The spring clips


238


are connected to the free ends of the wire


242


which extend from the loop.




As shown in

FIG. 6

, the drums


202


are clamped to the column


204


by a single flexible strap


244


which is looped around the lower portion of the drums. The strap


244


has a J-shaped metal hook


246


attached to each of the two free ends


248


of the strap. Each hook


246


has a slot


250


opposite a semicircular hook end


252


. A free end


248


of the strap


244


extends through the slot


250


around a rectangular member


254


, back through the same slot


250


and then beneath the strap. Hence, when tension is removed from the strap


244


, it is possible to adjust the distance between the two hooks


246


. Such an adjustment would be needed if drums of different sizes were to be substituted.




The central column


204


has two side flanges


256


which extend rearwardly from the front wall


232


a distance of about one and ¼ inch. Narrow slots


258


are formed in each side flange


256


to receive the hook ends


252


of the hooks


246


. Tension is applied to the strap


244


by a tension applying mechanism


260


. The mechanism


260


has a rod


262


which extends rearwardly from the central column


204


. A rear block


264


has a threaded hole which receives the threaded end


266


of the rod


262


. The rear block


264


may be a solid block of metal, or it may be a bent strip, as shown. The rod


262


is passed through a hole


268


formed in the flexible strap


244


. The hole


268


is preferably formed by breaking a minimum number of the threads of the strap which extend circumferentially. The block


264


may be about two inches wide and engages the strap across this width. The front end


270


of the rod


262


extends through an opening


272


in the front wall


232


of the column


204


at about the level of the hook slots


258


. The front end


270


of the rod


262


is also threaded and is received within a conventional cam crank


274


. The cam crank


274


is of the type which permits the rod to be rotated when the crank is turned, to thereby draw the rear block


264


closer to the column


204


and thereby apply tension to the strap and secure the drums to the column. By releasing the cam crank


274


, tension is taken off the strap, and the forward tipping of the column


204


is made possible.




To facilitate tilting the column away from the barrel to allow the cover to be pivoted, a quick release mechanism on the strap tightening shaft may be employed as illustrated. Rotating the crank handle draws the rear block


264


and the column


204


together taking up slack in the barrel clamping strap. Rapid release is facilitated by a threaded spring loaded pawl which is engaged by the threaded shaft.




In normal operations a spring holds the pawl engaged with the threads of the shaft so that rotating the shaft causes the rear block


264


to approach the crankshaft which is mounted for nonthreaded rotation on the shaft. To rapidly release the column from the rod, the pawl is pushed against the spring, disengaging the threads on the pawl from the shaft allowing the shaft to slide towards the rear block


264


releasing tension on the clamping straps holding the barrels together with the column


204


. Other conventional arrangements for releasing the tension may also be used, for example a cam connected to the handle, whereby pivoting of the handle causes a slackening of tension.




As shown in

FIG. 4

, the tipping of the column


204


may be desirable in an embodiment in which the countertop


218


is connected by a hinge


276


to one of the drums


202


. The hinge


276


is connected to the drum


202


by two hinge attachment pins


278


, which extend through holes in the rim


214


of the drum. The hinge


276


permits the countertop


218


to be pivoted sidewardly about the hinge. However, it will be noted that the column


204


with its projecting spouts


206


interferes with this sideward pivoting. Therefore, it is necessary to tip the column forward, to then lift the countertop, to return the column to its upright position, and to then rest the underside of the countertop on top of the spouts


206


. With the countertop in this pivoted orientation, both drums are accessible for maintenance. More particularly, with the countertop hinged to the wastewater receptacle


210


, and supported on the spouts, it is possible to unclip the strap


244


and remove the fresh water receptacle


208


and replace it with another. This would permit prefilled and sanitized drums of fresh water to be changed out for the depleted drums. The wastewater receptacle


210


could then be drained of the used wash water.




An alternative approach to accessing the drums is shown on the washstand


200


, although both approaches need not necessarily be provided in a single washstand. As shown in

FIG. 1

, a paper towel and soap dispenser housing


280


is hinged to the upper ledge


282


of the countertop


218


by a hinge rod


284


. The hinge knuckles


286


on the countertop


218


are spaced frontwardly from the rear of the countertop and are positioned above the connecting trough


216


. The housing


280


knuckles


288


are also positioned along the front wall of the housing, and are connected to the countertop knuckles


286


such that the entire housing may be pivoted frontwardly until it abuts against the upwardly protruding spouts


206


. In this pivoted condition, the housing exposes two access holes


290


in the countertop upper ledge


282


which permit a drainage or supply hose to be introduced into the drums without requiring the countertop


218


to be itself moved. The housing


280


may have front walls


292


disposed at an angle to each other, for example about


90


degrees, which corresponds to the angle between the upwardly inclined portions


294


of the spouts, so that the tilted housing rests comfortably between the spouts. The housing


280


has a cover
