Description




BACKGROUND OF THE INVENTION




The invention relates to a trash container transporting system. More particularly, the invention relates to a carrier for allowing which allows a plurality of trash or refuse containers to be easily transported along a trash pickup route, whereby empty and full containers are quickly and easily interchanged along the route.




Trash pickup is usually accomplished in one of two ways: small containers located along a pickup route are dumped into a truck having a large hopper as the truck travels the route; or the entire container—usually termed a “dumpster”—is picked up and towed to a waste disposal site.




Typically transporting the entire dumpster is reserved only for large garbage containers, which are typically only used by organizations with large waste disposal needs. However, the bulk of waste carting is for smaller businesses and residential customers who each produce a relatively smaller amount of trash, and thus require smaller containers.




One standard container in common use today is configured as a tall rectangular box, having a pair of wheels on one side, a handle on that side, and a cross bar on the opposite side from the wheels. Because these containers have a fairly high capacity, they are now in common usage, they are often difficult to handle, and are especially difficult to lift for dumping purposes. Accordingly, lifting and dumping these containers is often a two person operation.




U.S. Pat. No. 3,762,738 to Christina and U.S. Pat. No. 3,907,117 to Williams both disclose carts for transporting old-style barrel shaped trash cans.




U.S. Pat. No. 5,135,245 to Pagone discloses a recycling cart which holds a plurality of arcuate bottomed containers to allow various recyclable waste to be separately compartmentalized therein. The contains have arcuate bottoms so that they would tip over without the cart and would thus not likely be stolen.




U.S. Pat. No. Re. 27,437 to Bailey, discloses a double refuse container holder which seemingly requires that the cans be hoisted in order to place the cans within the straps of the holder. Bailey is unsuitable for quick pickup and delivery of refuse containers. U.S. Pat. No. 3,306,464 to Rogers discloses a receptacle holder and support for use by barrel shaped trash cans.




While these units may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present invention as disclosed hereafter.




SUMMARY OF THE INVENTION




It is an object of the invention to produce a trash container transporting system which allows refuse containers to be easily picked up and dropped off. Accordingly, a trailer is provided having a plurality of cradles upon which the refuse containers are easily positioned upon, and are easily removed from.




It is another object of the invention to provide a trash container transporting system which securely holds the refuse container, so that they can be transported over public highways while staying securely in their cradles. Accordingly, a latching system is provided on the carrier, for engaging and securely holding each refuse container.




It is a further object of the invention to provide a trash container transporting system which is operable by one person. Accordingly, a handle is provided immediately adjacent to each cradle for operating the latching system associated with that cradle, so that the trash container may be tipped against the cradle and pushed into the cradle while the latching system is operated.




The invention is a carrier for refuse containers of the type having a front and a back, a top and a bottom, wheels located on the bottom back, and a cross bar located on the front midway between the top and bottom, comprising a longitudinal main beam and a plurality of cradles supported by the main beam. Each cradle is adapted to support one of the refuse containers from the bottom thereof. A locking mechanism includes a latch hook extending from the main beam centered with respect to the cradle to selectively lock onto the cross bar of the trash receptacle, and an operating handle extending alongside the cradle for engaging the latch hook.




To the accomplishment of the above and related objects the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.

for maintaining the refuse container


20


thereon and resisting forces in the longitudinal direction during motion of the carrier


10


. The cradle


32


is generally t-shaped, having a short leg


35


.




Each cradle


32


is attached to the main beam


30


by a vertical support


37


extending substantially perpendicularly upward from the cradle


32


, against which the refuse container


20


rests when it is on the cradle


32


. A spacer beam


38


may be interposed between the vertical support


37


and the main beam


30


to distance the vertical support


37


from the main beam


30


, to allow for the cross bar recess


29


and to provide room for locking mechanisms to operate, as will be described in further detail below.




The cradles


32


are preferably arranged in pairs, whereby each cradle


32


is preferably mated with another cradle


32


at the same longitudinal position along the main beam


30


, but on an opposite side of the main beam


30


, by a transverse support


36


, which is generally an extension of the short leg


35


of both cradles


32


, extending coplanar thereto. Accordingly, a rigid cradle network is provided by a combination of two cradles


32


, vertical supports


37


which attach each cradle to the main beam


30


, and the transverse support


36


which attaches the two cradles


32


and is coplanar with both.




Each refuse container


20


is held in place on the cradle, resisting transverse forces by a combination of the vertical support


37


and a latching mechanism


50


. One latching mechanism


50


is provided for and associated with each of the cradles


32


, in order to securely hold each of the refuse containers


20


placed therein. The latching mechanisms


50


helps facilitates the easy pick-up and drop-off of the refuse containers in accordance with the primary goals of the invention.




Each latching mechanism


50


comprises a latch hook


52


, extending transverse to the main beam centered within one of the cradles


32


, toward said cradle, for selectively engaging the cross bar


27


of the refuse container


20


. Each latching mechanism also comprises an operating handle


54


which extends alongside said cradle


32


, for allowing a user to actuate the operating handle


54


while pushing the refuse container


20


onto the cradle


32


.




In

FIG. 2

, two latching mechanisms


50


are illustrated, symmetrically mounted on the main beam


30


. The latching mechanisms


50


are in different operative positions to illustrate modes of operation thereof. The latch hook


52


and cross bar


27


are both separately mounted to a back plate


55


. Both the latch hook


52


and cross bar


27


are mounted for rotary movement with respect to the back plate on parallel axis. As illustrated, the latch hook


52


selectively pivots upward to release the cross bar


27


, or pivots downward to lock onto the cross bar


27


. A cam


56


is fixedly mounted to the release handle


43


at the back plate


55


to cause the latch hook


52


to raise when the operating handle


54


is lifted.





FIG. 3

illustrates the carrier


10


in use, wherein a first refuse container


20




a


is located on a first cradle


32




a


, and a second refuse container


20




b


is about to be stowed on a second cradle


32




b


. A first latching mechanism


50




a


, associated with the first cradle


32




a


and first refuse container


20




a


is naturally locked in place. A second latching mechanism


50




b


, however, has been released so that it is ready to secure onto the cross bar


27




b


of the second refuse container


20




b


. The second latching mechanism


50




b


has a second operating handle


54




b


, which has caused its associated second latch hook


52




b


to be raised in anticipation of the second refuse container


20




b


being moved into position. The second refuse container


20




b


is tilted backward on the wheels, by the handle


23


and leaned against the second cradle


32




b


. The refuse container


20




b


is then pushed up onto the second cradle


32




b


, and the operating handle


54




b


is released to cause the latch hook


52




b


to lock onto the cross bar


27




b


. Now, both the first refuse container


20




a


and the second refuse container


20




b


are ready for transporting.




Referring now back to

FIG. 1

, it can be noted that the operating handle is a compound structure, having an operating handle main portion


60


which extends transverse to main beam


30


and extends between the cradles


32


, and an operating handle axle


62


which extends along the main beam toward the back plate


55


which is centered with respect to the cradle. The operating handle axle


62


thus allows the operating handle main portion


60


to be positioned in a location where it is easily used by a single person while hoisting or lowering the refuse containers, while allowing the latch hook to be centered on the cradle to grab the cross bar in the middle of the refuse container. Each operating handle axle


62


is supported so that it is maintained parallel to the main beam


30


by an axle support


64


mounted to the main beam


30


, which allows the operating handle axle


62


to rotate freely therethrough.





FIG. 4

illustrates another portion of the carrier


10


, wherein a vehicle axle


70


extends transverse to, and supports the main beam


30


. By having one or more vehicle axles


70


, carrier


10


may be towed behind a motor vehicle. In general, each trailer can easily have ten or more carriers. Trailers can be combined so that a single motor vehicle can easily tow twenty or thirty refuse containers.




In conclusion, herein is presented a carrier for trash containers having a plurality of cradles for supporting the trash containers, which allows the trash containers to be easily and safely transported, and allows the trash containers to be quickly and easily picked up and dropped off.
