     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a wheeled platform for a container which is adapted to provide a centrally located compartment for receiving a five gallon bucket surrounded by a plurality of peripheral compartments located on the platform for further storage utility and easy, convenient access to the user of the wheeled platform. 
     2. Description of Related Art 
     The use of bucket containers for transporting tools, gardening implements, or more generally for carrying materials in vehicles, boating activities or home work performing activities is well known in the prior art. The prior art is replete with a myriad of special purpose designs developed for specific objectives and requirements. For example, Schiek, U.S. Pat. No. 1,328,458, discloses a bucket in which the bottom is so constructed that a base normally forming a part of the bucket may be quickly disconnected from the bucket bottom when the occasion requires and when connected therewith will enable the bucket to be slid easily and noiselessly, from point to point, over a supporting surface without injury to the bucket bottom. In Bowers, U.S. Pat. No. 2,321,981, there is disclosed a scrub bucket assembly consisting of a mobile base which serves as a support for a frame, which is adapted to receive a pair of bucket-like receptacles, one adapted to contain soap suds to be used in scrubbing floors, walls, windows, and the like, and the other receptacles adapted to contain clear rinsing water. 
     Reynolds, U.S. Pat. No. 2,772,889, discloses a wheeled support for containers having a bottom flange thereon. The wheeled carrier is adjustable to adapt to various diameters of containers and provides a clamping means along the outer periphery thereof so as to grip a downwardly projecting flange on the bottom of the container. Bard, U.S. Pat. No. 2,947,548, discloses a wheeled bucket used in floor cleaning operations having a resilient bumper assembly installed along the lower periphery so as to prevent damage to the bucket or furniture which it may bump into. 
     Hampton, U.S. Pat. No. 5,806,867, discloses a bucket trolley having a resilient engaging wall for retaining a standard size bucket containing a load. The trolley includes a set of wheels and an interchangeable handle. The bucket is retained by the resilient engaging wall such that the trolley is lifted along with the bucket for moving up and down stairs. Stephan, U.S. Pat. No. 5,472,220, discloses a dolly with an upwardly extending edge that conforms to the size of a standard five gallon bucket. The upstanding edge on the dolly prevents the bucket from tipping as it is pushed or pulled around the worksite. The upstanding edge also contains tightening means in the form of thumb screws at 90° circumferentially spaced intervals, which are hand tightened to prevent the bucket from tipping. Finally, Tagariello, U.S. Pat. No. 6,135,467, discloses a bucket stand which includes a base and at least one receptacle extending generally vertically, provided for storage of elongated items. The stand includes clamp means to secure the bucket or pail to the base with an interference fit. The base includes circumferentially spaced struts connected to the ring base which clamps the bucket. Receptacles, connected to the ring base by the struts, are provided to provide storage of elongated items. 
     Although these various prior art bucket stands or dollies solve some of the shortcomings of the prior art, many provide solutions to single problems identified with the use of prior art bucket stands or dollies. Therefore, what is needed is a wheeled container platform that does not waste material by using deep wells high lips, or expanded peripheral envelope to prevent the bucket from tipping; does not require the time consuming effort of having to loosen screws or thumb screws in order to secure or remove the bucket to or from the platform; is cost effective, easy to manufacture and ergonomically stable in all of its various uses; is convenient to use by providing additional storage receptacles which are conveniently accessible to the user while being easily moved about the worksite without concern of the wheeled platform and associated bucket tipping over. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The invention is a wheeled platform for a container adapted to have a bucket mounted thereon that avoids all of the shortcomings of the prior art. Specifically, the invention is a wheeled platform for material handling which is particularly useful for tradesmen, repairmen, home handymen, or car detailers which is not anticipated or rendered obvious or even implied by any of the known prior art, considered by itself or in combination. 
     The present invention consists of a wheeled platform base molded from a high density polyethylene plastic material and having a plurality of upstanding flanges molded therein to define several compartments in combination with a centrally disposed cylindrical compartment adapted to receive a conventional cylindrically shaped five gallon bucket. The five gallon bucket may serve different purposes depending on the user of the wheeled platform. For the tradesman, the bucket may contain an assortment of tools or materials such as paint, tile cement, drywall joint compound or a sealer used in conjunction with the type of work to be performed. For example, a painter, with the use of a form fit throwaway liner that conforms to the bucket and a standard paint roller, can use the invention to perform his work having continuous, ergonomically easy access to the paint and the wheeled platform providing mobility to move the bucket of paint about the worksite. A drywall finisher or tile installer that uses the wheeled platform of the invention to store a bucket of drywall joint compound or tile cement has complete mobility during the course of the job activity since the wheeled platform lends itself to be easily moved about the worksite with little effort. It is no longer necessary for the tradesman to carry the bucket with the material therein to or from, as well as about the worksite since the bucket is completely mobile and is moveable with the simple touch and light pressure exerted by the hand. 
     The base platform also includes a plurality of compartments surrounding the centrally disposed bucket compartment. These compartments are defined by integrally molding upright flanges to the base. The compartments are configured to provide storage for tools and/or materials which may be required for specific applications. For example, a contractor&#39;s wheeled platform may include of one or two large storage compartments for miscellaneous tools or supplies to be stored whereof use may be required frequently while performing the specific work function. Other units may have a plurality of compartments surrounding the centrally disposed bucket compartment to enable storage of accessory containers of cleaners, spot removers, etc., for example, which may be used in the process of washing a passenger car or RV vehicle. Still other applications combine the wheeled platform with specific accessories which are conveniently stored surrounding the bucket as required for specific applications. 
     The platform base is supported by four wheels mounted to the bottom of the base member of the wheeled platform to provide the mobility to allow the wheeled platform to be conveniently moved from one worksite to another or from the tradesman&#39;s vehicle to and about the worksite. Two of these wheels have lockable mechanisms so that when using the wheeled platform on an inclined surface, such as a driveway, these two wheels of the platform can be easily locked to maintain the unit in a specified place. For an ice fisherman, the four wheels are easily removed and replaced with small skis so as to allow the platform base and associated bucket to be easily conveyed across ice or snow. 
     The wheeled platform has an additional feature to provide additional utility to the bucket arrangement during use in the many applications conceivable by the user. At approximately 180° apart, locations about the circumference of the upstanding flange that defines the centrally disposed cylindrical bucket compartment is an integrally molded upwardly and radially extending housing frame consisting of four walls in which one end of a bungee cord is mounted with the use of a locator pin. The opposite end of the resilient bungee cord is attached to the bucket near the top rim of the bucket. By securely attaching the bucket to the wheeled platform with the use of an S-hook in combination with a bungee cord, the handle of the bucket can now be used as a convenient means of lifting the wheeled platform with the bucket mounted thereon to move the entire combined unit from different horizontal levels, across interruptions in the surface upon which the combined unit is placed when it cannot be conveyed by its wheels or over uneven terrains around the worksite. 
     The primary object of the invention is to provide a wheeled platform adapted to receive a standard five gallon bucket for use by tradesman, homeowners, gardeners, or car detailers as an ergonomically convenient material handling device to use in a variety of applications wherein tools and/or material supplies may be conveyed to and from the worksite as well as conveniently used at the worksite while performing the work function. Additionally, it is an object that the wheeled platform and associated bucket provide maximum flexibility while in use by furnishing significant degrees of freedom of motions and mobility with the bucket being transferable on the wheeled platform or alternatively transporting the wheeled platform and bucket as a single unit from one level to another by carrying the platform through the use of the handle on the bucket and the bungee cords secured between the platform and the bucket. Additionally, the bucket is readily storable on the platform and can easily be removed therefrom by unhooking the bungee cords. 
     A further object of the invention is to provide an improved wheeled platform for conveniently and reliably retaining a standard five gallon bucket on the wheeled platform, with the combination further providing a convenient means for alternate ways of providing a material handling device for carrying tools and/or material supplies, as well as for storing the same, so as to be ergonomically accessible to the user while performing the job function. The combination may be used for carrying hand tools, power tools and/or material supplies to and from the worksite and for maintaining such in an orderly fashion as well as to provide easy, convenient access during the performance of the job function. 
     It is a further object of the invention to provide a combination wheeled platform and related bucket which is simple and of sturdy construction while also being lightweight and easy to transport to and from as well as about a worksite. 
     It is still a further object of the invention to provide a combination bucket and platform dolly for performing a variety of tradesman&#39;s and homeowner&#39;s tasks in which tools and material supplies can be stored and transported such that these tools and materials are readily accessible by the user during the performance of the specific tasks. 
     Other advantages and features of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings and claims.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings, in particular  FIGS. 1-5 , a first preferred embodiment of the wheeled platform dolly  10  of the present invention is shown therein. The embodiment is equipped with storage compartments surrounding a centrally disposed cylindrical compartment which is sized to receive a cylindrically shaped five gallon bucket. The wheeled platform base  12  is molded from a high density polyethylene plastic material having a centrally spaced upstanding cylindrical flange  14  molded therein for receiving the five gallon bucket  16 . Although the preferred embodiment discloses the use of a cylindrical bucket, the peripheral shape or configuration of the bucket may be of any shape. Therefore, the upstanding cylindrical flange can also be of any convenient shape complimentary to the peripheral shape of the bucket container. Surrounding the cylindrical flange  14  is a plurality of upstanding flanges defining several different sized compartments  18  which are molded specifically to receive miscellaneous containers of various shapes and sizes which would typically be used in conjunction with the task at hand. For example, for car detailers, various types of spot and grease removers or polish containers may be stored in the compartments surrounding the centrally located cylindrical flange so as to be conveniently accessible to the car detailer. Further, the larger compartments can be used to store sponges, rags, small cleaning brushes or pliable tubes containing lubricants or cleaning products. 
     To provide the structural integrity for the weight of the five gallon bucket container as well as the several conveniently disposed container compartments surrounding the bucket, the underside of the base is adequately ribbed  20  between the upper  22  and lower  24  surfaces of the wheeled platform base  12  to avoid any deflection of either the upper  22  or lower surface  24  of the wheeled platform base  12 . The flanges for each of the compartments  26 ,  28 ,  30 ,  32  surrounding the centrally disposed compartment  15 , including the cylindrical flange  14  that defines the centrally disposed compartment  15 , extend above the top or surface  22  of the wheeled base platform  12  to provide adequate stability to the containers intended to be stored in each of these compartments. Each of the compartments have a floor or bottom surface  33  which may be solid as shown in  FIG. 6  or alternatively each compartment floor  33  may have designated openings  72  therein for drainage purposes as is disclosed hereinafter. 
     The respective ends  34 ,  36  of the wheeled platform dolly  10  have been rounded off to avoid the use of sharp corners along the sidewall of the base platform. Sharp corners are avoided to prevent the wheeled platform dolly  10  from catching onto another sharp corner as the wheeled platform is moved about the worksite. 
     Four caster wheels  38  are attached to the lower surface  24  of the wheeled platform base  12  proximate the four corners thereof. The caster wheels  38  are alike and have respective ground engaging surfaces extending a distance from the bottom surface of the wheeled platform base  12  so as to be generally co-planar with one another. Each caster wheel  38  is adapted to swivel and permit rotational motion, as well as longitudinal movement of the wheeled platform base  12 . Alternatively, it is conceivable to use a straight through independent axle (not shown) on one of the sets of caster wheels while only caster wheels are used on the other set of wheels of the wheeled platform base  12 . Such arrangement will permit uni-directional or 360° rotation of each caster wheel  38  on the plane of contact with the ground surface. Alternatively, the caster wheels  38  may be mounted on a single axle which runs parallel to the ground from one side of the wheeled platform to the opposite side thereof. Preferably, however, the configuration shown in the figures commonly known as a caster wheel assembly is preferred. 
     To maintain the wheeled platform dolly  10  in position on an uneven or inclined terrain, it is foreseeable that caster wheels with an individual locking mechanism (not shown) be used so as to keep the wheeled platform in place by locking at least two of the caster wheels of the assembly. 
     A common problem of prior art single bucket carriers is the instability of the carrier when the bucket  16  is filled with water or a heavy material compound such as tile cement. Accordingly, prior art devices are known to place the wheels as far apart as possible or use additional supporting structure on the bucket dolly to securely hold the bucket to the dolly to prevent it from tipping over. Such arrangements are more expensive and present a larger overall envelope than what is necessary with the current invention. 
     As shown in detail circle B of  FIG. 1 , the present invention utilizes a simple solution to such a problem by providing two small upright housing frames  40  molded into the top surface  22  of the wheeled platform base  12  at approximately 180° apart locations and integral with the upstanding flange  14  for the centrally located cylindrical compartment  15  into which the bucket  16  is placed. Each housing frame  40  consists of three upstanding walls  42 ,  44 ,  46  integrally molded with the cylindrical flange  14  surrounding the bucket compartment  15  and with the top surface  22  of the wheeled platform base  12 . The walls  42 ,  46  that are oriented approximately radially extending from the cylindrical flange have at their center a small aperture  48  to accommodate a small push pin as will be discussed hereinafter. 
     As shown in detail circle A of  FIG. 1 , the typical five gallon bucket  16  is molded with a concentric radially extending downwardly projecting skirt  50  and a plurality of reinforcement collars  51  integral with the outside diameter of the five gallon bucket  16 . Between the skirt  50  and the reinforcement collars  51 , there is generally an outward projection  53  in the wall, which is integrally molded with the skirt  50  at opposing 180° apart circumferential segments. At these two locations, the handle  52  of the bucket  16  is secured to the sidewall of the bucket  16 . The skirt  50  and reinforcement collars  51  arrangement as well as the outward projection  53  provide the structural integrity for the bucket walls to prevent them from radially deflecting when there is a significant weight of material content in the bucket, i.e. water, sand, slag, tile cement, drywall compound, and the like. This skirt  50  is also used to provide a point of attachment for a biasing member or bungee cord  54  as shown in  FIG. 1  and circle A so that the bucket  16  and wheeled platform base  12  can be secured together as a unit. The attachment point consists of a small hole  56  that is drilled in the upper part of the top ledge of the skirt  50  as shown in  FIG. 1 . A link member  58  having one end terminating in a 180° reverse bend hook  60  is installed into one end of an EPDM rubber strap coupling member or bungee cord  54  having terminal ends  62  of a rectangular enlarged end portion with a hole  64  provided centrally therethrough. The reverse bend hook  60  is installed onto one end of the EPDM rubber strap while the opposite end of the bungee cord  54  is mounted in the respective housing frame  40  molded to the top surface  22  of the base  12  of the wheeled platform. A push pin  66  is placed through the hole  48  of each radially extending wall  42 ,  46  of the housing frame  40 , as well as through the hole  64  of the rectangular enlarged terminal end portion  62  at one end of the bungee cord  54  to secure one end of the bungee cord to the base  12  of the wheeled platform. 
     The opposite end of the link member  58  is provided with a reverse bend hook  60  also, but of a larger radius, so that the two ends of the link member  58  face each other but are also offset from one another. Further, the end of the reverse bend hook  60  of the opposite end of the link member  58  has an additional offset which is created by a bend of the end in the outward direction. To the terminating end of the outward bend of the link member  58  is mounted an axle cap nut  70  which is retained to the end of the link member by the interference fingers of the axle cap nut  70 . 
     With one end of the bungee strap  54  secured into the housing frame  40  on the top surface  22  of the base  12  on both sides of the wheeled platform, the bungee cords  54  are each resiliently extended and the end of the link member  58  is placed in the small hole  56  that is drilled into the upper part of the top ledge of the skirt  50  of the bucket wall along each side of the bucket  16  following by mounting the axle cap  70  on the end to secure the end to the bucket. With a bungee cord  54  that is properly sized to the distance between the base  12  of the wheeled platform and the hole  56  in the skirt  50  of the bucket wall, a holding force is applied by the resiliency of the bungee cord  54  so that the bungee cord  54 , as so installed, will prevent the bucket from being unstable when filled with a heavy load such as sand, water, cement, or dry wall spackling compound. Also when it is necessary to lift the wheeled platform dolly  10  for any reason, the handle  52  of the bucket  16  can now be used to lift the bucket  16  and the wheeled platform dolly  10  will lift with the bucket  16  so that the complete assembly can be carried up the stairs, over an impediment, or over uneven terrain, etc. The through holes  72  in the lower surface of the wheeled platform base  12  are for purposes of drainage so as to prevent build up of any spilled material from the bucket  16  in the compartments  15 ,  26 ,  28 ,  30 ,  32 . 
     With reference to  FIG. 6 , there is shown another embodiment of the wheeled platform. This alternate embodiment provides two large compartments  18  surrounding the centrally disposed cylindrical compartment  15  which holds the five gallon bucket  16 . 
     This arrangement is more for a general purpose dolly for a contractor than a specific use application. Like the preferred embodiment, flanges  74 ,  76  are integrally molded to the upper surface  22  of the wheeled platform base  12  to define a centrally disposed compartment  15  sized to contain a five gallon bucket  16  with two large surrounding compartments  18  for containing selective material used in conjunction with the work to be performed. For example, plumbers would use such dolly to transport pipe, fixtures, valves, miscellaneous plumbing appurtenances as well as the heavier plumbing tools, i.e. pipe wrenches, piper cutters, etc., while the various smaller tools and associated materials, i.e. soldering gun, solder, pipe compound, and small hand tools can be carried in the two compartments surrounding the centrally located five gallon bucket  16  compartment. 
     As in the preferred embodiment, the top surface  22  of the base is provided with integrally molded two small upright housing frames  40  consisting of a four wall structure on either side of the centrally disposed cylindrical flange  14  at approximately 180° apart location in which is mounted one end of a bungee cord  54  as earlier disclosed. The opposite end of the bungee cord  54  is located in the small hole placed in the top ledge of the skirt  50  of the five gallon bucket  16  and the bungee cord  54  length is sized so as to place a downward biasing force on the bucket  16  when each end of the bungee cord  54  is attached to the platform and bucket  16  to provide stability to the bucket  16  and allow the bucket handle  52  to be used to pick up the combined bucket  16  and platform when it is necessary to traverse the wheeled platform and bucket  16  over an uneven terrain or up and down steps or stairs. 
       FIG. 7  illustrates yet another variant of the invention. This embodiment of the wheeled platform dolly  10  is proposed for the car detailer to enable the handling of two five gallon buckets  16  mounted side-by-side on the platform. One bucket is intended to contain soapy water for washing purposes while a second bucket is intended to contain rinse water proposed for rinsing purposes. This embodiment can also be used by a contractor where one bucket contains a material compound associated with the specific work activity, i.e. tile cement, grout, drywall mud, etc., and the second bucket contains some form of cleaner or rinse water to clean the tools related to the job activity. 
     As earlier disclosed, the double bucket platform shown in  FIG. 7 , like the preferred embodiment, is made from a high density polyethylene plastic material having a base  12  defined by an upper and lower surface  22 ,  24  with a specified thickness therebetween. Extending from the upper surface  22  of the base  12  is a pair of cylindrical flanges  14  molded adjacent to each other for receiving a five gallon bucket  16  in each of the pair of cylindrical flanges  14 . Surrounding the pair of cylindrical flanges is a plurality of upstanding flanges  18  defining several different storage compartments in the base  12 . Each compartment  18  being molded in the base  12  to receive miscellaneous containers of various shapes and sizes to be stored therein and which would most typically be used in conjunction with the specific job to be performed by the contractor. For example, floor installers can use this type of double bucket arrangement to carry a bucket of cement in one bucket compartment while the second compartment can accommodate the new tile material to be stacked thereon so that the installer can conveniently guide the wheeled double bucket about the worksite with the new tile and cement conveniently reachable by hand. The installer&#39;s tools can be stored in the compartments surrounding the double bucket arrangement. Drywall installers can use one bucket compartment to store the mud to be applied while the second bucket contains rinse water to keep the tools rinsed and clean. Further, the drywall tape, as well as all of the installer&#39;s tools can be easily stored in the surrounding compartments. 
     To provide the structural integrity for the weight of the five gallon bucket container as well as the several conveniently disposed containers surrounding the bucket, the underside of the base is adequately ribbed  20  between the upper and lower surfaces  22 ,  24  of the base  12  to avoid any deflection of the lower surface  24  of the base  12 . The flanges  18  for each of the compartments surrounding the centrally disposed compartment  15 , including the flanges  14  that define the centrally disposed compartment  15 , extend above the top surface  22  of the base  12  platform to provide adequate stability to the containers intended to be stored in each of these compartments. 
     The respective ends  34 ,  36  of the wheeled platform base  12  have been rounded off to avoid the use of sharp corners along the sidewall of the base platform. Sharp corners are avoided to prevent the wheeled platform from catching onto another sharp corner as the wheeled platform is moved about the worksite. 
     Six caster wheels  38  are attached to the lower surface  24  of the double bucket wheeled platform. One caster  38  is mounted proximate the four corners thereof while two caster wheels are mounted at the center along opposing sides thereof (not shown). The caster wheels  38  are alike and have respective ground engaging surfaces extending a distance from the bottom surface of the base so as to be generally co-planar with one another. Each caster wheel is adapted to swivel and permit rotational motion, as well as longitudinal movement of the wheeled platform. Alternatively, it is conceivable to use a straight through independent axle (not shown) on one of the sets of wheels while only caster wheels are used on the other set of wheels of the wheeled platform. Such arrangement will permit uni-directional or 360° rotation of each caster wheel on the plane of contact with the ground surface. Alternatively, the caster wheels  38  may be mounted on a single axle which runs parallel to the ground from one side of the wheeled platform to the opposite side thereof. Preferably, however, the configuration shown in the figures commonly known as a caster wheel assembly is preferred. 
     Like the preferred embodiment, to maintain the wheeled platform in position on an uneven or inclined terrain, it is foreseeable that some of the caster wheels  38  have an individual locking mechanism (not shown) so as to keep the wheeled platform in place by locking at least two of the caster wheels of the assembly. 
     As earlier discussed, a common problem of prior art bucket carriers is the instability of the carrier when the bucket is filled with water. 
     Like the preferred embodiment, the double bucket wheeled platform is provided with two small upright housing frames  40  molded into the top surface  22  of the base  12  at approximately 180° apart locations and integral with the top surface  22  of the base  12  and each upstanding flange  14  for the adjacent cylindrical compartment  15  into which each bucket  16  is located. Each housing frame  40  consists of three upstanding walls  42 ,  44 ,  46  integrally molded with the cylindrical flange  14  surrounding each bucket compartment and with the top surface  22  of the base as disclosed with respect to the preferred embodiment. The walls  42 ,  46  that are oriented approximately radially extending from the cylindrical flange  14  have at their center a small aperture to accommodate a small push pin as will be discussed hereinafter. 
     As hereinabove disclosed, the skirt  50  and reinforcement collars  51  on each of the buckets provide the structural integrity for the bucket  16  walls to prevent them from radially deflecting when there is a significant weight of material content in the bucket, i.e. water, sand, slag, tile cement, drywall compound, and the like. This skirt  50  is also used to provide a point of attachment for a bungee cord  54  so that the bucket  16  and wheeled platform base  12  can be secured together as a unit as heretofore disclosed. The attachment point consists of a small hole  56  that is drilled in the upper part of the top ledge of the skirt  50  as shown in detail circle A of  FIG. 1 . A link member  58  having one end terminating in a 180° reverse bend hook  60  is installed into one end of an EPDM rubber strap coupling member or bungee strap  54  having terminal ends  62  of a rectangular enlarged end portion with a hole  64  provided centrally therethrough. The hook  60  is installed into one end of the EPDM rubber strap while the opposite end of the bungee strap  54  is mounted in the respective housing frame  40  molded to the top surface  22  of the base  12  of the wheeled platform. A push pin  66  is placed through the hole  48  of each radially extending walls  42 ,  46  of the housing frame  40 , as well as through the hole  64  of the rectangular enlarged terminal end portion  62  at one end of the bungee cord  54  to secure one end of the bungee cord  54  to the base  12  of the wheeled platform. 
     The opposite end of the link member  58  is provided with a reverse bend hook  60  also, but of a larger radius, so that the two ends of the link member  58  face each other but are also offset from one another. Further, the end of the reverse bend hook of the opposite end of the link member has an additional offset which is created by a bend of the end in the outward direction. To the terminating end of the outward bend of the link member  58  is mounted an axle cap nut  70  after the link member  58  is placed through the hole  56  in the skirt  50  of the bucket which is retained to the end of the link member by the interference fingers of the axle cap nut  70 . 
     With one end of the bungee strap  54  secured into the housing frame  40  on the top surface  22  of the base  12  on both sides of the wheeled platform, the bungee cords  54  are each resiliently extended and the opposite end of the link  58  is placed in the small hole  56  that is drilled into the upper part of the top ledge of the skirt  50  of the bucket wall along each side of each of the buckets  16 . The axle cap nut  70  is thereafter placed on the end of the link  58 . With a bungee cord  54  that is properly sized for the distance between the base  12  of the wheeled platform and the hole  56  in the skirt  50  of the bucket wall, a biasing force is applied by the resiliency of the bungee cord  54  so that the bungee cord  54 , as so installed, will prevent the bucket  16  from being unstable when filled with a heavy load such as sand, water, cement, or dry wall spackling compound. Also when it is necessary to lift the wheeled platform base  12  for any reason, the handle  52  of either of the buckets can now be used to lift the bucket  16  and the wheeled platform  12  will lift with the buckets  16  so that the complete assembly can be carried up the stairs, over an impediment, or over uneven terrain, etc. 
     As can be seen in  FIG. 2 , the lower surface  24  in each of the cylindrical flange compartments  18  have through holes  72  so that spills of liquid or powder material will not accumulate in the bucket compartment and interfere with the bucket installation. 
       FIG. 8  illustrates a further variant of the wheeled platform and associated bucket. In  FIG. 8  each of the caster wheels  38  have been removed from the bottom of the platform and replaced with small ski runners  88  for use by the ice fisherman. The wheeled platform base  12  with attached ski runners  88  is used to convey fishing gear from a vehicle to and from an ice shanty located at the fishing site. The storage platform and bucket arrangement is used to carry an ice auger and a tip up fishing rig. The smaller compartments  18  can be used to store miscellaneous fishing equipment which are cumbersome to carry and often require several trips from the fishing site to and from the vehicle. For obvious reasons the bottom surface of the base in each compartment is provided with through holes  72  as shown in  FIG. 2  so liquid that could develop as a result of ice accumulation can melt and run off through the through holes  72  in the bottom surface  24  of the base  12  of the wheeled platform.
