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.
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'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'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's and homeowner'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.
Referring now to the drawings, in particular
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
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
As shown in detail circle A of
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
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.
As earlier disclosed, the double bucket platform shown in
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
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
From the foregoing, it will be seen that the invention is one well adapted to obtain all the objects herein set forth, together with other advantages which are obvious and which are inherent to the structure.
It will be understood that certain features and sub-combinations are of utility and may be employed without reference to other features and sub-combinations. This is contemplated by and well within the scope of the claims. Although several embodiments have been shown in the drawings, may other embodiments may be made of the invention without departing from the scope thereof. It is to be understood that all matter herein set forth shown in the accompanying drawings is to be interpreted as illustrated and not in a limiting sense.
