Description




TECHNICAL FIELD




This invention relates to pallets for storing goods, and particularly relates to the storage of items on wheels such as casters.




BACKGROUND OF THE INVENTION




Goods are often effectively and efficiently stored and transported in stacked configuration. Stacking goods maximizes the use of available storage and transportation space. In addition, it is desirable to manipulate such goods with a forklift for quick handling of the goods. This saves labor and time. Some goods, however, are difficult to store and transport in stacked configuration and are not easily manipulated with a forklift. Wheeled items such as photocopiers on casters are an example of such goods which are difficult to handle.




Typically, an item such as a photocopier on casters has to be placed on skids and secured to the skids to be manipulated with a forklift and stored and transported in stacked configuration. Normally, two laborers and a forklift are required to load and secure a photocopier to skids. The photocopier is secured to the skids by bolting the photocopier to the skids. This is a time consuming task which takes at least about 20 minutes per item.




Alternatively, wheeled items such as photocopiers on casters can be stored on an open floor without stacking the items. Without stacking, however, photocopiers occupy a large space. In addition, photocopiers, unsecured to skids, are difficult to manipulate with a forklift and are rolled about the floor instead. This requires a lot of labor and is time consuming.




Another problem with storing items such as photocopiers on an open floor is that photocopiers are controlled in inventory by serial number. When a specific serial number is requested, an employee must locate the unit within the bulk storage area and retrieve the particular photocopier by moving other photocopiers that obstruct its path. The desired unit is then pushed to the area in which it is to be processed. This is also undesirably time consuming.




Therefore, there is a need for a system for storing and transporting wheeled items such as photocopiers in a manner that allows stacking of the items and their manipulation with a forklift. There is also a need for a system for storing and transporting wheeled items with aligned and offset casters.




SUMMARY OF THE INVENTION




The present invention solves the above-described problems in the prior art by providing a pallet for a wheeled item comprising a plurality of tracks and a plurality of ramps mounted to a base frame having openings for receiving forklift arms. The plurality of tracks and plurality of ramps are structured and arranged so that when the item is shifted on the wheels from the plurality of tracks along the plurality of ramps, the undercarriage of the wheeled item comes to rest on a support surface of the pallet. With the undercarriage of the wheeled item resting on the pallet, rather than the wheels, the wheeled item can be secured to the pallet for storage and transportation. Therefore, the pallet of the present invention provides for swift loading of the wheeled item onto the pallet. The pallet allows the wheeled item to be manipulated with a forklift and stored and transported in a stacked configuration. Manipulation with a forklift reduces labor and time required for handling the wheeled item. In addition, stacking of the wheeled item provides for more effective and efficient use of storage and transportation space.




More particularly, the pallet of this invention is suitable for storing and transporting wheeled items comprising an undercarriage and wheels extending from the undercarriage. The pallet of this invention can accommodate wheeled items having aligned or offset casters. The pallet base frame desirably has openings for receiving forklift arms and extends along a longitudinal axis from a first end to a second end. The plurality of tracks are mounted on the base frame for receiving the wheels of the wheeled item. The plurality of tracks each extend from the first end toward the second end of the base frame substantially parallel to and spaced from one another. The plurality of ramps are also mounted to the base frame and slope from the plurality of tracks toward the base frame. Each of the plurality of tracks extend from the one end of the base frame to a distal end and the plurality of ramps extend from respective distal ends of the plurality of tracks without interrupting an adjacent one of the plurality of tracks. The plurality of ramps are directed so as not to interfere with the travel of casters of the wheeled item along the tracks. Depending on the configuration of the casters or wheels of the wheeled item, the plurality of ramps can extend longitudinally or diagonally from respective distal ends of the plurality of tracks with respect to the longitudinal axis of the base frame or can extend laterally from the plurality of tracks.




For wheeled items with aligned casters, the pallet desirably includes ramps which slope laterally or diagonally from the corresponding plurality of tracks. For storing wheeled items with offset casters, particularly significantly offset casters, the ramps of the pallet desirably extend longitudinally or diagonally from the respective distal ends of the plurality of tracks so that the offset casters do not interfere with adjacent tracks.




Desirably, the pallet of this invention includes a support adjacent the plurality of tracks extending from the pallet in a direction away from the base frame so that when the wheeled item is shifted on the wheels from the plurality of tracks along the plurality of ramps, the undercarriage of the wheeled item comes to rest on the support. In other words, the support extends upwardly from the pallet when the pallet is in loading position on a floor, and preferably, the support extends away from the base of the pallet beyond the plurality of tracks. Desirably, the plurality of ramps of the pallet are sloped toward the base frame relative to the support such that at least a portion of the weight of the wheeled item is shifted from the wheels of the item to the support when the wheeled item is shifted laterally on the wheels from the plurality of tracks, along the plurality of ramps, so that the undercarriage of the wheeled item comes to rest on the support.




According to a simplistic embodiment, the pallet of the present invention includes a base frame, a support mounted on the base frame and having a support surface for receiving the wheels of the item, and a plurality of ramps mounted on the base frame and sloping from proximate the support surface toward the base frame through recesses in the support. The support and the plurality of the ramps are structured and arranged so that when the wheeled item is shifted on the wheels from the support surface along the plurality of ramps, the undercarriage of the wheeled item comes to rest on the support surface.




According to a particular embodiment for a wheeled item having offset wheels, the pallet includes a first pair of tracks and a second pair of tracks spaced inwardly from the first set of tracks. Each of the first and second pairs of tracks extend from the one end of the base frame to a distal end and the plurality of ramps extend from respective distal ends of the first and second pairs of tracks without interrupting an adjacent one of the first and second pairs of tracks. Desirably, the plurality of ramps extend longitudinally or diagonally from respective distal ends of the plurality of tracks.




According to another embodiment particularly suitable for wheeled items with aligned casters, the tracks of the pallet include first and second tracks mounted on the base frame for receiving the wheels of the item to be stored and transported. The first and second tracks extend from the first end of the base frame toward the second end and are substantially parallel and spaced from one another. In addition, the ramps of the pallet include first and second ramps. The first ramp is mounted on the base frame of the pallet between the first and second tracks and slopes laterally with respect to the longitudinal axis of the base frame from the first track toward the base frame and second track. The second ramp is mounted to the base frame such that the second track is between the first and second ramps. The second ramp slopes laterally with respect to the longitudinal axis from the second track toward the base frame. Accordingly, when the wheeled item is shifted on the wheels laterally with respect to the longitudinal axis from the first and second tracks along the first and second ramps, the undercarriage of the wheeled item comes to rest on the pallet.




Still more particularly, the pallet of this embodiment for an item with aligned casters desirably includes first and second supports for receiving the undercarriage of the wheeled item when the wheeled item is shifted laterally down the first and second ramps. The first support extends from the pallet between the first and second tracks and in a direction away from the base frame. Likewise, the second support extends from the pallet in a direction away from the base frame adjacent the second track. The second support is positioned so that the second track is between the first support and the second support.




Desirably, the first and second supports extend away from the base frame of the pallet beyond the first and second tracks and extend from the first and second ramps, respectively. Particularly, the first and second supports suitably comprise a plurality of members spaced from one another between the first and second ends of the base frame and extend substantially perpendicular to the first and second tracks. The first and second ramps of the pallet of this embodiment are sloped toward the base frame relative to the first and second supports such that at least a portion of the weight of the wheeled item is shifted from the wheels of the item to the first and second supports when the wheeled item is shifted laterally on the wheels from the first and second tracks, along the first and second ramps, so that the undercarriage of the wheeled item comes to rest on the first and second supports. The pallet of the present invention is particularly suitable for wheeled items set on casters.




The pallets of the present invention can include first and second side walls extending between the first and second ends of the base frame along respective opposite sides of the base frame from to prevent the wheeled item from rolling laterally off the pallet. In addition, the pallet can include a plurality of pins for securing a strap for holding the wheeled item onto the pallet.




The pallets of the present invention can be made out of a variety of materials, but are desirably made out of polymer resin and, in particular, are preferably made by injection molding with polymer resin such as high density polyethylene.




Accordingly, an object of the present invention is to provide a system for storing and transporting wheeled items in a stacked configuration.




Another object of the present invention is to provide a system for handling wheeled items with a forklift.




Still another object of the present invention is to provide a system for more efficiently storing and transporting wheeled items.




Yet another object of the present invention is to provide a pallet for storing and transporting wheeled items.




A further object of the present invention is to provide a pallet for storing and transporting wheeled items with offset casters.




Other objects, features, and advantages of the present invention will become apparent from the following detailed description, drawings, and claims.

DETAILED DESCRIPTION OF DRAWINGS




Turning now to the drawings in which like numerals reference like parts throughout the several views, a pallet


10


is shown for storing a wheeled item


12


which includes a set of aligned casters


14


extending beneath an undercarriage


16


. The loading of the pallet


10


with the wheeled item is illustrated in FIG.


3


.




Generally described, the pallet


10


includes a base frame


20


, a pair of tracks


22


and


24


for receiving the casters


14


of the wheeled item


12


, a pair of corresponding ramps


26


and


28


extending from respective tracks to the base frame, and two sets of support members


30


and


32


extending from the ramps away from the base frame. The pallet


10


can be made of a variety of materials provided that the pallet can withstand the weight of the item being stored and repeated handling such as with a forklift. Therefore, suitable materials for making the pallet


10


include wood, metal, and polymer resins such as plastic. Polymer resin is particularly desirable for forming the pallet


10


because many polymer resins are strong, durable, lightweight and relatively inexpensive. In addition, many polymer resins can be injection molded. Injection molding is a desirable method of making the pallet


10


. A particularly suitable resin is high density polyethylene.




As shown in

FIGS. 1 and 2

, the base frame


20


of the pallet


10


is substantially rectangular in shape and extends from a first end


34


to a second end


36


along a longitudinal axis and has respective first and second side walls


38


and


40


extending between the first and second ends. In addition, the base frame


20


has a first pair of forklift openings


41


extending from the first end


34


of the base frame to the second end


36


of the base frame and a second pair of forklift openings


42


extending from the first side wall


38


to the second side wall


40


so that the pallet


10


can be manipulated with a forklift from any side of the pallet. The forklift openings


42


are separated by integral middle supports


43


and


44


. The forklift openings


41


and


42


and the middle supports


43


and


44


form part of an underside


46


of the base frame


20


. The underside


46


of the base frame


20


faces downwardly and rests on the floor when the pallet


10


is being used for loading and storing an item. The base frame


20


extends from the underside


46


upwardly to top side


48


which supports the first and second tracks


22


and


24


, the first and second ramps


26


and


28


, and the first and second sets of support members


30


and


32


.




The first and second tracks


22


and


24


are integrally mounted to the base frame


20


and extend, substantially parallel to and spaced from one another, from the first end


34


to the second end


36


of the base frame. In other words, the first and second tracks


22


and


24


are parallel with the longitudinal axis of the pallet


10


. In addition, the first and second tracks


22


and


24


have respective planar surfaces


50


and


52


for receiving the casters


14


of the wheeled item


12


being loaded. The planar surfaces


50


and


52


of the tracks


22


and


24


are substantially horizontal and face upwardly when the pallet


10


is being loaded with or storing a wheeled item.




The first track


22


is positioned adjacent the first side wall


38


of the base frame


20


and the second track


24


is positioned between the first track and the second side wall


40


of the base frame. The first ramp


26


is mounted on the base frame


20


between the first and second tracks


22


and


24


and slopes laterally with respect to the longitudinal axis of the base frame from the first track, downwardly toward the top side


48


of the base frame and toward the second track. The second ramp


28


is mounted to the top side


48


of the base frame


20


such that the second track


24


is between the first ramp


26


and the second ramp. The second ramp


28


slopes laterally with respect to the longitudinal axis of the pallet


10


from the second track


24


, downwardly toward the top side


48


of the base frame


20


. In other words, the second ramp


28


slopes in the same direction as the first ramp


26


.




The set of first support members


30


extend upwardly and away from the first ramp


26


of the pallet


10


beyond the first and second tracks


22


and


24


and are spaced from one another from the first end


34


of the base frame


20


to the second end


36


of the base frame


20


. The first support members


30


are parallel to one another and each have an upwardly facing planar support surface


54


for contacting the undercarriage of the wheeled item


12


loaded on the pallet


10


. Likewise, the set of second support members


32


extend upwardly and away from the second ramp


28


of the pallet


10


and are spaced from one another from the first end


34


of the base frame to the second end


36


of the base frame. The second support members


32


are parallel to one another and each have an upwardly facing planar support surface


56


for receiving the undercarriage


16


of the wheeled item


12


being stored. The second support members


32


also extend upwardly beyond the first and second tracks


22


and


24


. Both the first and second support members


30


and


32


extend perpendicularly between the first and second tracks


22


and


24


.




The first and second ramps


26


and


28


slope downwardly relative to the planar support surfaces


54


and


56


of the respective first and second support members


30


and


32


, so that when the wheeled item


12


is shifted on its casters


14


laterally with respect to the longitudinal axis of the pallet


10


from the first and second tracks


22


and


24


along the first and second ramps, the undercarriage


16


of the wheeled item comes to rest on the planar support surfaces of the first and second support members and the casters of the wheeled item fall slightly downwardly from the undercarriage of the wheeled item. In other words, when the wheeled item


12


is shifted laterally along the first and second ramps


26


and


28


, the weight of the wheeled item comes to rest on the first and second supports


30


and


32


and the weight of the wheeled item shifts substantially from the casters


14


of the wheeled item to the first and second support members


30


and


32


of the pallet


10


. This is illustrated in FIG.


3


. With the weight of the wheeled item


12


off of the casters


14


and on the pallet


10


, the wheeled item can be secured to the pallet.




For securing the wheeled item


12


to the pallet


10


, the pallet includes a plurality of pins


58


disposed in recesses


60


in each of the first and second side walls


38


and


40


of the base frame


20


. After the wheeled item


12


is loaded onto the pallet and secured on top of the support members


30


and


32


, the wheeled item can be secured to the pallet


10


by extending one or more straps over the wheeled item and securing the ends of the straps to the pins


58


in the side walls


38


and


40


of the pallet as illustrated in FIG.


3


.




Accordingly, the wheeled item


12


can be easily loaded onto the pallet


10


by positioning the first end


34


of the pallet


10


adjacent a loading ramp


64


, rolling the wheeled item


12


up the loading ramp on the casters


14


of the wheeled item while aligning the casters with the first and second tracks


22


and


24


of the pallet, rolling the wheeled item along the first and second tracks until the casters of the wheeled item are between the first and second ends


34


and


36


of the pallet, and then shifting the wheeled item laterally on its casters down the first and second ramps


26


and


28


until the undercarriage


16


of the wheeled item comes to rest on top of the first and second support members


30


and


32


. The wheeled item


12


is then secured to the pallet


10


with one or more straps


62


as described above. Once loaded and secured on the pallet


10


, the wheeled item can be transported with a forklift.




The pallet


10


can be used to store and transport a variety of wheeled items including but not limited to photocopiers, furniture, safes, televisions, filing cabinets, automated teller machines, main frame computers, computer peripherals, equipment stands, gas grills, and the like. To accommodate the storage and transportation of such items, the pallet


10


can be virtually any size. This invention should not be limited to particular dimensions; however, for most applications, the pallet


10


will have a width from 30 to 80 inches, a length from 30 to 84 inches, a ramp angle from 5 to 40 degrees relative to the horizontal, a ramp length from 5 to 30 inches and support member heights from 2 to 10 inches above the forklift openings. According to a particular embodiment useful for storing and transporting wheeled items having 1 to 3 inch casters which are 16 to 22 inches apart, a width of 34 inches, and a length of 46 inches, the pallet has a width of 4 inches, a length of 48 inches, a track width of 6.5 inches, a ramp angle of 8.6 degrees with respect to the horizontal, and a support member height of 3½ inches from the top side of the base frame.




The pallet


10


enables wheeled items such as photocopy machines to be loaded and secured quickly. A wheeled item can be loaded and secured to the pallet


10


in 30 seconds or less. In addition, the pallet


10


saves space because the pallet allows wheeled items to be stored in multi-level racks. This saves space in storage facilities and in transportation vehicles. Furthermore, the pallet


10


allows wheeled items to be handled more quickly and efficiently because the wheeled items can be manipulated with a forklift after being loaded on the pallet, rather than being wheeled along the floor.




According to another embodiment of the present invention, a pallet


100


for storing wheeled items with offset casters is illustrated in the

FIGS. 4-7

. This pallet


100


is suitable for holding two types of wheeled items with offset casters. Loading of pallet


100


with these items is illustrated in

FIGS. 6 and 7

.




In

FIG. 6

, the pallet


100


is shown supporting a wheeled item


102


with double offset casters. This wheeled item


102


includes a pair of front casters


104


spaced from one another proximate one end of the wheeled item and a pair of rear caster


106


offset from the front casters proximate another end of the wheeled item. The rear casters


106


are offset inwardly from the front casters


104


. The front and rear casters


104


and


106


extend beneath the undercarriage


108


of the wheeled item.





FIG. 7

illustrates the pallet


100


holding a wheeled item


110


with a single offset caster. This wheeled item


110


also has a pair of front casters


114


proximate one end of the wheeled item and a pair of rear casters


116


proximate another end of the wheeled item. One of the rear casters


116


is offset inwardly from the corresponding front caster


114


. Again, the front and rear casters


114


and


116


extend downwardly from the undercarriage


118


of the wheeled item


110


.




The pallet


100


for wheeled items with offset casters includes a base frame


120


, best illustrated in FIG.


4


. The base frame


120


has a conventional pallet design that includes fork lift openings


122


extending from a first end


124


to a second end


126


. The pallet


100


also includes an upper frame


128


mounted to the base frame for supporting the wheeled items


102


or


110


. As with the pallet


10


illustrated in

FIGS. 1-3

, the pallet


100


for offset wheeled items can be made of a variety of materials provided that the pallet can withstand the weight of the item being stored and repeated handling with a forklift. Again, suitable materials for making the pallet


100


include wood, metal, and polymer resins such as plastic. A particularly suitable resin is high density polyethylene and the pallet


100


is desirably made by plastic molding techniques such as injection molding, rotary molding, or blow molding.




The base frame


120


and the upper frame


128


of the pallet


100


are substantially rectangular in shape and extend from the first end


124


to the second end


126


of the base frame along a longitudinal axis. The upper frame


128


includes an integral raised pallet support


130


for supporting the undercarriage of wheeled items loaded onto the pallet


100


. The raise pallet support


130


includes side portions


130


and


134


and a middle portion


136


between the side portions. The raised pallet support


130


forms a planar support surface


138


for contacting the undercarriage of the wheeled items.




Elongate planar tracks


140


,


142


,


144


,


146


,


148


, and


150


extend parallel to one another from the first end of the base frame


120


toward the second end


126


of the base frame between the side portions


132


and


134


of the raised pallet support


130


. Each of the tracks


140


,


142


,


144


,


146


,


148


, and


150


extend from the first end


124


of the base frame


120


to respective distal ends


152


,


154


,


156


,


158


,


160


, and


160


. the tracks


140


,


142


,


144


,


146


,


148


, and


150


are arranged in pairs for receiving casters of wheeled items.




Tracks


140


and


142


form a first outer pair of tracks. One of the outer tracks


140


extends adjacent a side wall


164


formed by one side portion


132


of the raised pallet support


130


. The other


142


of the outer pair of tracks extends along a side wall


166


formed by the opposite side portion


134


of the raised pallet support


130


. A pair of lateral ramps


168


and


170


formed by corresponding recesses


172


and


174


in the side portion


132


of the raised pallet support


130


slope from the first outer track


140


toward the base frame


120


and away from the opposite outer track


142


. One of the lateral ramps


168


is positioned toward the first end


124


of the base frame


120


and the other of the lateral ramps


170


is positioned proximate the distal end


152


of the first outer track


140


. Another ramp


175


extends laterally from the distal end


154


of the other outer track


142


and slopes laterally and downwardly toward the base frame


120


and the middle portion


136


of the raised pallet support


130


.




Elongate dividers


176


and


177


separate the first outer pair of tracks


140


and


142


from the adjacent second pair of tracks


144


and


146


. The second pair of tracks


144


and


146


are positioned between the outer tracks


140


and


142


and extend from the first end


124


of the base frame


120


longitudinally toward the second end


126


of the base frame to respective distal ends


156


and


158


. Longitudinal here means parallel to the longitudinal axis of the base frame


120


. Respective longitudinal ramps


180


and


182


extend from the distal ends


156


and


158


of the second pair of tracks


144


and


146


longitudinally toward the second end


126


of the base frame


120


. These longitudinal ramps


180


and


182


slope downwardly from the second pair of tracks


144


and


146


toward the base frame


120


. The longitudinal ramps


180


and


182


extend from the second pair of tracks


144


and


146


stop well short of the distal ends


152


and


154


of the adjacent outer tracks


140


and


142


and are disposed between the respective outer tracks and the middle portion


136


of the raised pallet support


130


.




The third and innermost pair of tracks


148


and


150


extend longitudinally adjacent respective ones of the second pair of tracks


146


and


148


. The middle portion


136


of the raised pallet support


130


separates the third pair of tracks


148


and


150


and dividers


184


and


186


separate the third pair of tracks from the second pair of tracks. The third pair of tracks


148


and


150


are much shorter than the second pair of tracks


144


and


146


. Longitudinal ramps


188


and


190


extend from the respective distal ends


160


and


162


of the third pair of tracks


148


and


150


and slope downwardly from the third pair of tracks toward the base frame


120


. The longitudinal ramps


188


and


190


also stop well short of the distal ends


156


and


158


of the second pair of tracks


144


and


146


.




A lateral divider


196


separates the longitudinal ramp


190


of one of the innermost tracks


150


from a ramp


198


sloping laterally from the adjacent track


146


downwardly toward the base frame


120


and toward the middle portion


136


of the raised pallet support


130


.





FIG. 6

illustrates the wheeled item


102


having double offset casters


106


mounted on the pallet


100


. The wheeled item


102


is shown in phantom lines. To load the wheeled item


102


, the wheeled item is loaded onto the pallet


100


by means such as a ramp or forklift so that the outwardly positioned front casters


104


travel along the outwardly positioned first pair of tracks


140


and


142


and the inwardly offset rear casters


106


travel along second pair of tracks


144


and


146


. The wheeled item


102


is pushed on the casters


104


and


106


along the ramps


144


,


146


,


148


, and


150


and then down the longitudinal ramps


180


,


182


,


188


, and


190


until the undercarriage


108


of the wheeled item rests fly on the planar support surface


138


of the raised pallet support


130


. The wheeled item


102


can then be secured to the pallet


100


with straps attached to pins


210


mounted in recesses


212


along with side portions


132


and


134


of the raised pallet support


130


.




It should be understood that although the ramps


180


,


182


,


188


, and


190


are illustrated as longitudinal, such ramps can be diagonally directed or otherwise laterally directed provided that the ramps do not intersect any of the adjacent ramps and interfere with the casters traveling down the tracks. Furthermore, the longitudinal ramps


180


,


182


,


188


, and


190


desirably slope so that the weight of the wheeled item


102


shifts from the casters to the raised pallet support


130


and the casters fall slightly downwardly from the undercarriage


108


.





FIG. 7

illustrates how the pallet


100


can also accommodate the wheeled item


110


with the single offset rear caster


116


. In this mode, the front casters


114


of the wheeled item


110


travel along the outermost pair of tracks


140


and


142


, one of the rear casters


116


travels along one of the outer tracks


140


, and the slightly inset one of the rear casters


116


travels along one of the second pair of tracks


146


. The front and rear casters


114


and


116


are then shifted laterally along the lateral ramps


168


,


170


,


175


, and


190


until the undercarriage


118


of the wheeled item


110


rests on the planar support surface


138


of the raised pallet support


130


. Again, the lateral ramps


168


,


170


,


175


, and


190


are sloped to a degree such that the weight of the wheeled item


110


shifts from the casters to the raised pallet support


130


and the casters fall slightly away from the wheeled item


130


. As with the other wheeled items, this wheeled item


110


can be secured to the pallet


100


with straps, or the like.




It should be understood that the foregoing relates to particular embodiments of the present invention, and that numerous changes may be made therein without departing from the scope of the invention as defined by the following claims.
