(10) Front-loading waste-collecting and hauling vehicles 12 are ubiquitous in the commercial refuse collection industry. Typically, when front-loading is employed, a heavy-duty vehicle or truck 12 is provided with a hydraulic-powered lift 13, including a pair of forks 14a and 14b situated to extend in front of the vehicle. The forks 14a and 14b of the truck 12 can be raised, lowered and tilted in front of the driver's cab so that an operator can see the forks, guide the forks into lifting engagement with a front-loadable refuse container 10 and lift the container with the forks. The portable trash container 10 is designed to be utilized in conjunction with a front-loading truck 12. Bulk items may be placed within the portable trash container 10, which is a portable, mesh, low profile container.

(11) As illustrated in FIG. 1, the portable trash container 10 is designed to accommodate of variety of items to be placed in the truck 12, such as a refrigerator 11. The front-loading truck 12 typically has a front cab 12a with a large refuse compartment 12b behind the cab. A hydraulic-powered lift 13, including a pair of forks 14a and 14b extend in front of the truck 12 that are adapted to be inserted into corresponding tubes 18a and 18b associated with the portable trash container 10. Typically tubes 18a and 18b having a rectangular cross section however, any suitable cross section that can receive the forks 14a and 14b can be used. The forks 14a and 14b are able to lift the portable trash container 10 from its initial, refuse collection position on the ground, then over the cab 12a of the truck 12 and invert the container 10 to dump its contents into the refuse compartment 12b located behind the cab for dumping the contents of the trash container there into.

(12) As seen in FIG. 2, the portable trash container 10 consists of an upper frame 20 supporting rectangular tubes 18a and 18b, a collapsible mesh box or container 22, a plurality of support straps 24, including at least first and second straps 24a and 24b, third strap 25 and a plurality of axles 26, including first, second and third axles 26a, 26b, and 26c, having wheels at each end thereof. The portable trash container 10 may be of any appropriate dimensions, with an exemplary height having a range between about 2.5 feet and 3.5 feet, a length having a range between about 5 feet and six feet, and width having a range between about 2.5 feet and 3.5 feet. The portable trash container 10 must be sufficiently large to accommodate a wide array of refuse items of different dimensions and weights, such as furniture, boxes, refrigerators, and any other desired products.

(13) FIG. 2 illustrates the portable trash container 10 in an extended state. The upper frame 20 consists of first and second side walls 20a and 20b, and first and second end walls 20c and 20d.

(14) The side walls 20a and 20b, and end walls 20c and 20d are preferably constructed of a flexible, yet sturdy fabric, such as a heavy nylon strap. The first and second side walls 20a and 20b may have any desired length, with an exemplary range between about 5 feet and six feet and extend the length of the sidewalls 22a and 22b of the mesh container 22. Preferably the fabric end walls 20c and 20d and the fabric sidewalls 20a and 20b are constructed of a single length of fabric forming the upper frame 20.

(15) The rectangular tubes 18a and 18b which accommodate the pair of hydraulic-powered forks 14a and 14b which extend from the truck 12 are disposed adjacent to the first and second end walls 20c and 20d.

(16) The rectangular tubes 18a and 18b support the portable trash container 10 and the item or items therein when the pair of forks 14a and 14b lift the container and dispose of the item within the truck. Each of the rectangular tubes 18a and 18b is constructed of a material such as metal and includes a cavity 19a and 19b there though, respectively, into which the forks 14a and 14b are inserted.

(17) The rectangular tubes 18a and 18b may be attached to first and second end walls 20c and 20d in any desired fashion. For example, the first and second end walls 20c and 20d can have sleeves 23a and 23b, respectively, secured thereto to receive the tubes 18a and 18b, respectively. The fabric end walls 20c and 20d can be secured to the inward facing sides of the sleeves 23a and 23b, respectively. Alternatively, the sleeves 23a and 23b can be formed as an extension of the mesh, i.e., the interwoven strands of metal, fiber, or other flexible/ductile materials, forming end walls 20c and 20d of the upper frame 20. Handles 27a and 27b can be connected to the sleeves 23a and 23b, best shown in FIG. 4.

(18) As illustrated in FIG. 2, the two side walls 20a and 20b are fully extended. It should be noted that since the two side walls 20a and 20b are constructed of a flexible strap of fabric, the rectangular tubes 18a and 18b may be situated closer to each other by narrowing the distance between the two end walls 20c and 20d. Therefore, a wide array of the pair of forks 14a and 14b with varying sizes between the two forks may be utilized with the portable trash container 10. One or more straps 17, such as first and second straps 17a and 17b are attached to the first side wall 20a of upper frame 20. The purpose of the straps 17a and 17b is to provide extra support when the portable trash container 10 is being suspended over the cab 12a of the truck 12 and inverted to dump its contents into the refuse compartment 12b. As illustrated in FIG. 1, the straps 17a and 17b may be secured about a cross bar 13a of the hydraulic-powered lift 13 by any means such as with a Velcro fastener.

(19) As shown in FIGS. 1-4, the portable trash container 10 includes support rods 29a and 29b which are mounted at one end to u-shaped brackets 31a, 31b, respectively, that in turn are affixed to collars 33b (only one of which is shown), respectively, that are mounted to the ends of axle 26b. Projections 35b (only one of which is shown) extending upward from the collars 33b are attached to the U-shaped brackets 31a,31b by a pin so that the brackets and the attached support rods 29a and 29b have restricted movement in a single plane whereby the support rods 29a,29b can move between a position substantially parallel to axle 26b as shown in FIG. 3 to a position substantially perpendicular to axle 26b as shown in FIG. 2. The support rods 29a and 29b are each disposed in a sleeve 37a,37b, respectively, which is secured to the two side walls 20a and 20b of the upper frame 20.

(20) The support rods 29a and 29b are provided to strengthen the side walls 22a and 22b of the mesh container when the latter is fully open as shown in FIG. 2. The support rods 29a and 29b ensure that the mesh container does not collapse when it is raised over the driver's cab and turned over to dump the contents into the refuse container behind the driver's cab.

(21) As illustrated in FIG. 3, the portable trash container 10 is in a collapsed state. The two side walls 20a and 20b of the upper frame 20 are caused to be curved inward toward each other because the support rods 29a and 29b within the sleeve 37a,37b, move downwards with respect to collars 33a and 33b, respectively, that are mounted to the ends of axle 26b to a location a location parallel are to the axle 26b. When the portable trash container 10 is in the collapsed state as shown in FIG. 3, it can be rolled up beginning with the tube 18a within the sleeve 23a until it reaches the tube 18b within the sleeve 23b.

(22) The mesh container 22 is a net barrier textile in which the strands of material forming the mesh container are looped or knotted at their intersections, resulting in a fabric with open spaces between the strands of material. Typically, the mesh container 22 is constructed of connected strands of metal, fiber, or other flexible/ductile materials. The material from which the mesh container 22 must be robust and durable so as to support a variety of items with varying shapes and weights. For example, the mesh container 22 may be constructed of plastic coated steel cable, or alternatively braided nylon or a similar material. Further, the nominal mesh openings in the mesh container 22 formed between the connected strands of material may have sizes of any desired dimension.

(23) The mesh container 22 is secured to the upper frame 20 by any desired fashion such as by sewing the mesh container to the flexible strap forming the side walls 20a and 20b and end walls 20c and 20d. The attachment must be sturdy enough such that a particularly cumbersome or heavy article of refuse will not sever the connection between the mesh container 22 and the portable trash container 10.

(24) The support straps 24, including first and second straps 24a and 24b are attached to the bottom surface 22e of container 22, to the first and second end walls 22c and 22d of the mesh container, and to the first and second end walls 20c and 20d of the upper frame 20. Typically, the support straps 24a and 24b will be constructed of the same material as the first and second end walls 20c and 20d and the first and second side walls 20a and 20b, although they may be constructed of any desired material. The straps 24a and 24b are designed to provide additional support to the portable trash container 10. A first end 28a and 28b of the first and second straps 24a and 24b, respectively, attach to the first end wall 20c. The straps 24a and 24b extend about the mesh container 22, as illustrated in FIG. 2, and attach to the second end wall 20d at a second end 30a and 30b of the first and second straps 24a and 24b, respectively. The first end 28a and 28b and the second end 30a and 30b may attach in any desired fashion, such as being sewn thereto or with an adhesive.

(25) A third support strap 25 extends around the container 22 and is attached to the first and second side walls 22a and 22b, respectively and to the first and second end walls 22c and 22d, respectively. The third support strap 25 can be disposed between the upper frame 20 and the bottom surface 22e of mesh container 22. The strap 25 and 24b are designed to provide additional support to the portable trash container 10.

(26) As illustrated in FIG. 2 and FIG. 4, the plurality of axles 26, including first, second and third axles 26a, 26b, and 26c (26a-26c) are disposed below the bottom wall 22b of the mesh container 22 and the support straps 24. The axles 26a-26c may have any desired length of about 3 feet. The axles 26a-26c are disposed within elongated sleeves or housings 32a, 32b, and 32c (32a-32c), respectively. Housings 32a-32c are typically lengths of material which may be attached directly to the bottom wall 22b of the mesh container 22, or to the first and second straps 24a and 24b, or a combination thereof. The axles 26a-26c are rotatable within the housings 32a-32c. Each of the axles 26a-26c has a wheel 34 on both ends, which allows the portable trash container 10 to be easily wheeled around. The wheels 34 may be mounted to the axles 26a-26c in any desired manner.

(27) A method of use is provided using a portable trash container 10 with a hydraulic-powered lift 13 having a pair of forks 14a and 14b extending from a truck 12. The method includes providing the portable trash container 10 with an upper frame 20 constructed of first and second side walls 20a and 20b and first and second end walls 20c and 20d and a collapsible mesh container 22 secured to the upper frame. Further, a pair of tubes 18a and 18b is secured to the first and second side walls 20c and 20d. The collapsible mesh container 22 can be moved in a collapsed state to a location away from the truck 12 using handle 27a. Then, the mesh container can be expanded as shown in FIG. 2 with the support rods 29a,29b moved to a position substantially perpendicular to axle 26b. The one or more items can be placed within the collapsible mesh container and the collapsible mesh container 22 can be moved to a location adjacent the hydraulic-powered lift 13 having a pair of forks 14a and 14b extending from the truck 12. The pair of forks 14a and 14b are inserted into the pair of tubes 18a and 18b, and the forks are raised to raise the collapsible mesh container 22 while in an extended state above the cab of the truck. The collapsible mesh container is inverted and dumped so that the item therein is dumped into a refuse compartment 12b behind the cab of the truck 12. Note that the support rods 29a,29b prevent the container from collapsing when the container is inverted prior to dumping the contents into the refuse compartment.
