Primary Examiner-David Schonberg Assistant Examiner-John A. Pekar  ABSTRACT A trash cart supported on wheels for transporting a plurality of trash contained in plastic trash bags and having a relatively large opening covered by a lid that,
can selectively close said opening for the loading and unloading of bags containing trash within the cart.
8 Claims, 5 Drawing Figures TRASH CART trash cart that is particularly suited to the transport over short distances of plastic bags containing trash and garbage.
Prior art has developed a number of containers and I vehicles for the storage and transport of trash. These include garbage cans with handles that can be lifted and carried from one spot to another over relatively short distances without extreme physical exertion. Other devices include provision of plastic bags that are disposable along with the garbage or trash that they contain.- The usual practice with these plastic bags is to stuff the trash or garbage in the bags and then secure a closure of the top of the bag by means of paper encased wire that is twisted to form a secure closure.
It has been a practice in the past to place the empty plastic bags in open disposition within a garbage can and folding over the top portions of the bag over the rim of the garbage can prior to loading the trash into the bag. After the garbage is loaded into the bag contained within the garbage can, the folded over portions of the bag are unfolded and at least partially twisted and then the bag is removed from the can and the top of the bag is twisted further and the twist tie" or paper or plastic contained wire is twisted around the neck of the bag to form a closure. Bags are then placed in a convenient storage area such as a garage or in an area near the home and then are transported on a periodic basis from that location to a garbage truck which comes usually once a week in most areas.
An alternative to the above procedure in the past has been to simply place the trash in the bag without utilizing the garbage can and again as immediately described above storing the bags in a convenient place near the home such as a garage, basement or other area near the home and then further transporting them across the lawn or residential property to the area where the trash is ultimately collected by a garbage truck.
Both of the immediately above described procedures have been found to be more sanitary, more convenient, and requiring less exertion than simply dumping the trash or garabage into a garbage can and then storing the garbage cans in a place where otherwise plastic bags would be stored and then moving the garbage cans to the point of collection by the garbage truck.
All of the above described means and methods of collecting and storage of trash from the point of disposal within the home to the point of collection by thegarbage truck periodically require the transport of either trash filled bags or garbage cans from one location to another within the curtilage of the residential home. This is an inconvenient method and one often requiring considerable exertion particularly if the distance between the point of storage of trash after placement in bags or cans and the point at which the garbage truck picks up same is considerable.
Accordingly, it is an object of this invention to provide an inexpensive and convenient means of both storing trash after placement within plastic bags and transport of same to the point of collection by the garbage truck. This and other objects of this invention are achieved by the provision of a box-like structure having a substantially curved superstructure in the shape of a lid that can be removed from the cart and wheels provided in order to roll the cart from one location to an other.
These and other objects of this invention can be appreciated from the following specifications and claims.

AS SHOWN ON THE DRAWINGS FIG. 1 isa three-dimensional projection of a trash cart 10. The trash cart has a body portion 12 comprising four side portions 14, 16, 18 and 20. The body 12 is preferably made of a sheet metal such as an aluminum alloy. Starboard side portion 14 is in the shape of a rectangle having the longer side thereof running along a substantial portion of the length of the cart 10.
Side portion 18 is parallel to and on the port side of the cart 12 and has substantially the same length as the side portion 14 but a considerably higher height indicated by the edge 22 between side portion 18 and front portion 16 as compared with the edge portion 24 corresponding to the height of the side portion 14 and being the edge between port portion 14 and the front portion 16.
Front and aft portions 16 and 20, respectively, are substantially congruent and are in the shape of trapezoids having a width corresponding to the substantial portion of the width of the cart 10 as exemplified by the bottomedge 26 of the front portion 16 in meeting the bottom surface of the bottom portion 28. The side portions 14, 16, 18, 20 and the bottom portion 28 are preferably made of the same material and can be joined together by welding or other appropriate securing means in forming a rigid box-like structure.
Forward and aft lid members 30 and 32, respectively, are hingeably attached to the top edge of the trapezoidal-like front and aft sections 16 and 20, respectively. These lid members 30, 32 have an upwardly extending curved top portion 34 extending from the top ledge 36 of the port side portion 18 to the top ledge surface 38 of the starboard side portion 14. Handles 38 are secured near the acme of the curved portion 34 on the exterior surface thereof near the boundary of lid portions 30, 32 indicated at the aft portion top edge 40 of the top portion 34 of the lid member 30.
Forward and aft portions 42 are secured to the forward edge 44 of the forward lid member 30 and the after edge of the after member 32 respectively.
An axle S0.is provided having downwardly extending bracket leg portions 52 and 54 respectively on the port mounted thereon. Tires 60 may be provided for a ground engaging surface of the wheels 56, 58. A forward resting post 61 is provided near the forward end of the cart and has a stopper-like portion 62 which is preferably made of rubber for providing a three point resting configuration in conjunction with the wheels 56, 58 when the cart is at rest. The post 60 may be integral with another tubular element 64 that extends forwardly and upwardly from the post 60 to form a handle tube projection element 66 to which a gripping device 68 may be secured. The gripping device 68 is preferably made of rubber and is in the shape of a cylinder enclosing the tube-like portion 68 and providing a secure gripping element for the manual raising and pulling or pushing of the cart from one location to another.
In FIG. 2 a cross-sectional view through the apparatus in FIG. 1 discloses a trash bag 70 containing trash and having a twist tie comprising plastic enclosed wire 72 twisted and knotted about the, neck 74 of the bag 70. It can be appreciated from the view of the apparatus shown in FIG. 2 that the bag lies entirely within thecart and that the cart is substantially lengthy to contain several bags when the lids 30, 32 are closed.
It can also be appreciated from the apparatus shown in FIG. 1 that when the lids 30, 32 are in an open condition, a bag may be placed within the interior surface of the curved top section 34 to facilitate theplacing of bags during loading and unloading operations.
FIG. 3 illustrates an alternative embodiment of the cart similar to the one shown in FIG. 1 with the exception that in place of the post tubular and handle structure 60, 64, 66 a forward wheel structure 80 and a forward handle structure 82 are provided.
A toe lock device as illustrated in the wheel structure in 80 in FIG. 4 is provided-This toe lock is operable to prevent rotation of the caster structure.
The wheel structure 80 is essentially a caster structure. It comprises a wheel 84 attached to an axle 86 which is journallably mounted on a fender structure 88. The fender structure is in the shape of a ring having flat sides and rounded corners that-surround the central portion of the wheel 84. The ring'or fender structure 88 extends in a substintially horizontal direction. The fender or ring structure 88 is fixed to a bracket member 90 which is rotatably mounted to the bottom 50 of the cart structure 10.
The handle 82 is in the form of a tubular L having a vertically lower depending portion 92 fixedly attached, preferably by means of screws 94 to the forward face 21 of the'closure structure 12. The handle may have a rubber or plastic grip portion 96 attached tothe exterior forward end of the handle portion 82. Another alternative embodiment of the invention is illustrated in FIG. 5. The trash cart 10 therein described is precisely identical to that described and shown in FIGS. 3 and 4 with the exception that instead of the double hinged lid 32, 34 shown in FIG. 3, there is provided a single lid 98 that is simply lifted off the box-like structure 12. The handles and exterior configuration of a single lid 98 are identical to those of the double configuration 32, 34.
