DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1, 2 and 3 illustrate a grass hopper cart 12, which consists of a cabinet 14 and a structure 16 within the cabinet 14, for holding a standard paper bag 18 in an opened stationary position (see FIG. 7). A hopper 20 placed into the cabinet 14 above the holding structure 16, so that grass cuttings dumped into the hopper 20 will enter the paper bag 18 for proper disposal.
The cabinet 14 includes a bottom wall 22, with a pair of side walls 24 extending upwardly from the bottom wall 22. A pair of end walls 26 extend upwardly from the bottom wall 22, to form a compartment 28 therein for the holding structure 16 and the hopper 20.
The holding structure 16 is a wire frame 30 sized to fit into the standard paper bag 18, so as to keep the standard paper bag 18 in the opened stationary position. Each of the side walls 24 of the cabinet 14 has a horizontal slot 32 therethrough. The wire frame 30 has extending from each opposite side of its top end, a pair of hooks 34 to engage with one horizontal slot 32 in one side wall 24 of the cabinet 14, so as to suspend the wire frame 30 with the standard paper bag 18 therefrom.
The hopper 20 is a generally funnel-shaped container 36, having a lip 38 about its upper periphery to sit upon the open top of the cabinet 14, so that it will guide the grass cuttings into the standard paper bag 18 below.
When hopper 20 is placed upon cabinet 14, lip 38 comes to rest upon a rectangular supporting surface formed by the tops of side walls 24 and end walls 26. This relationship is shown in the detail of FIG. 12.
The cabinet 14 further includes a plurality of wheel units 40, mounted to the underside of the bottom wall 22, to make the cabinet 14 portable. It can be moved easily from place to place by the wheel units 40 rolled upon a flat ground surface 42. One of the side walls 24 of the cabinet 14 has a large opening 43 therethrough, so that the paper bag 18 can be easily removed from and installed onto the wire frame 30.
The grass hopper cart 12, as shown in FIGS. 1 through 6, further contains a portable staircase ramp 44 and an assembly 46, for coupling the portable staircase ramp 44 to one of the side walls 24 of the cabinet 14. A person can stand upon the portable staircase ramp 44, to dump the grass cuttings into the hopper 20.
The portable staircase ramp 44 consists of a base plate 48 and a pair of riser side rails 50, with each extending upwardly perpendicular from a rear corner of the base plate 48. A cross rail 52 extends horizontally between the upper ends of the riser side rails 50. A pair of stringer side rails 54 are also provided. Each extends upwardly at an angle from a front corner of the base plate 48, to connect with the upper end of one riser side rail 50. A plurality of support rails 56 extend horizontally in spaced apart parallel positions between the riser side rails 50 and the stringer side rails 54, about each side of the base plate 48. A stair tread 58 is mounted horizontally between two support rails 56. A platform 60 is mounted horizontally between the riser side rails 50 and the stringer side rails 54, above the highest stair tread 58.
The coupling assembly 46 includes one side wall 24 of the cabinet 14, having a pair of spaced apart vertical slots 62 therethrough. A pair of connector tabs 64 are affixed in a spaced apart relationship, to the back of the cross rail 52. The connector tabs 64 can engage with the vertical slots 62 in the side wall 24 of the cabinet 14.
The portable staircase ramp 44 further contains a plurality of spring biased wheel units 66, mounted to the underside of the base plate 48 (see FIG. 4). A plurality of legs 68 are mounted to the underside of the base plate 48. The legs 68 are shorter in length than the spring biased wheel units 66. When a person steps onto the portable staircase ramp 44, the weight will cause the spring biased wheel units 66 to collapse. The base plate 48 will be supported on the legs 68 to keep the portable staircase ramp 44 in a stationary position, even when the connector tabs 64 are in engagement with the vertical slots 62 in the side wall 24 of the cabinet 14.
A second type of hopper 20a, shown in FIGS. 8, 9, 10 and 11 includes a bottom wall 70 across a bottom portion of the generally funnel-shaped container 36, so as to mix various materials therein. An exit pipe chute 72 extends downwardly from the bottom wall 70. A sliding damper 74 is in the exit pipe chute 72, so as to open and close the exit pipe chute 72, to transfer the mixed material into other receptacles.
A third type of hopper 20b, as shown in FIG. 11, contains a wet and dry vacuum unit 76 built therein. A shredder unit 78 is also built therein. Various materials can be sucked into the hopper 20b and shredded into smaller particles, to be deposited into the paper bag 18.
The wet and dry vacuum unit 76 includes a suction motor 80. an electrical cord 82 is connected to the suction motor 80. A plug 84 is connected to a distal end of the electrical cord 82, so that it can engage with a socket to provide power to the suction motor 80. An elongated hose 86 is connected to the suction motor 80, so as to draw the various materials into the shredder unit 78 by the suction motor 80. The motor and fan of the vacuum unit 76 are disposed in conventional fashion at the top of and inside the container formed by hopper 20b. Grass cuttings are picked up in hose 86 and conducted by vacuum into hopper 20b.
In the embodiment employing shredder unit 78 in addition to vacuum unit 76, vacuum unit 76 transports cuttings to shredder unit 78. Shredded cuttings are then discharged to the paper bag supported by wire frame 30, in the manner of the first embodiment employing hopper 20 (see FIG. 1).
