DETAILED DESCRIPTION OF THE INVENTION


FIG. 1 is a full side view of a device 1 of this invention and FIG. 2 is a full front view. There is shown two adjacent, space-apart, parallel struts 2 which form a portion of the back of the device 1. Each strut 2 has a distal end 3 and a near end 4, and in the there is shown a handle 5 attached to the near ends 4. The distal ends 3 are attached to a platform 6 (See FIGS. 2 and 13) all of which will be discussed in detail infra. The distal ends 3 of the struts 2 have an axle 7 through them which supports wheels 8. For this invention, the wheels 8 should be at least 3 inches in diameter, but can be larger, and most preferred is 4¾ inches in diameter.


There is a plurality of cross members 9 extending from one strut 2 to the other strut 2 to stabilize the form of the device 1, and also to allow for certain attachments and for holding equipment as will be discussed infra. Although these cross members 9 can be bolted onto the struts 2, it is preferred that such cross members 9 be welded to the struts 2.


Also shown in FIG. 2 is an extended (telescopic) wheel bar 10 and wheel 11 for the wheel bar 10. The extended wheel bar 10 has a distal end 12 and a near end 13 and the wheel 11 is rotatably mounted on the distal end 12. The near end 13 is fastened to a cross member 9 at the back of the device 1. It is fastened by being rotatably attached to a welded hinge plate 14 that is attached to the cross member 9. Thus, the wheel bar 10 and the wheel 11 are designed to collapse and fit up against the cross member 9 for storage as shown in FIG. 1. FIG. 3 is a full front view of the device 1.



FIG. 4 is a full back view of the device 1 in which like numbers refer to like components as shown in FIGS. 1 and 2.


Also shown is a back plate 15 fixedly mounted on the back of the device 1 and near the distal ends 4 of the strut 2. The back plate 15 forms of the novel system for adjusting the funnel 16, wherein the detail of the funnel 16 will be described infra. The back plate 15 has two parallel, adjacent, evenly spaced, vertical tubular rails 17 attached to it. Each vertical tubular rail has vertically aligned openings 27.


The funnel 16 is removable. Aside from the funnel top 18, the funnel 16 is comprised of four, lower vertical panels 19 that are hinged onto the bottom edges 20 of the funnel top 18 by hinges that will be discussed infra. The panels 19 form a box-like structure 23(see FIG. 8B) on the bottom of the funnel top 18. The panels 19 have attached to them, spring clips 21 (see FIG. 11), that are mounted on the outside surface of the lower vertical panels 19, and are used for holding a trash bag 22 (FIG. 1) on the funnel 16.


Shown in FIG. 4 is a back panel 24(19), which is the back panel of the box-like structure 23. The back panel 24 has fixedly mounted on it, parallel, spaced-apart, bars 28 (see FIG. 5) that have vertical clips (or buttons) 25 attached to them, that align with and have the width of the openings 27 on the back plate 15.


The bars 28 are attached to the back panel 24 as shown in FIG. 6, wherein it is shown that the bars 28 are affixed at the top 29 of the bar 28. The side panel of the vertical tubular rail 26 has been removed so that the relationship of the bar 28 and the vertical tubular rail 26 can be illustrated.


In use, the bar 28 with the vertical clips 25 inserts into the vertical tubular rail 26, and the vertical clips 25 insert into openings 27 in the back plate 15 and hold the funnel 16 and box-like structure 23 in place. To adjust the funnel 16, the clips 25 are removed from the openings 27 by pressing on the back plate 15 and elevating or dropping the funnel 16, until the desired height is obtained, and then the buttons or clips 25 are re-inserted back into the openings 27. FIG. 7 is a full top view of the combination of the bar 28 and the vertical tubular rail 26.


The details of the back plate 15 and the vertical clips or buttons 25, and the back panel 24 and the openings 27 can best be viewed in FIG. 5, which is an enlarged view of said panel and plate.



FIG. 6 illustrates the alignment and interface between the back plate 15 and the vertical clips 25, and the back panel 24 and the openings 27. It should be noted that the buttons or clips 25


In this manner, the trash bag 22 can be filled sequentially from bottom to top without worrying about the trash bag 22 slipping or moving on the device.


The adjustable, extendable bar wheel 10 is affixed to a middle cross member 9 at the back of the back plate 15 which allows the easy transport of the device 1. When the clean up job is finished, or when the trash bag 22 is full, then the device will allow the easy transport to the street or any other denoted dumping site for the trash.


To facilitate the handling of the trash bag 22, and to ensure that the trash bag 22 remains with the device 1 during transport, there is used a strap 37, shown in FIG. 1.


Turning now to a detailed discussion of the funnel 16, reference is made to FIGS. 8A and 8B wherein it is shown in FIG. 8A the funnel 16, showing the funnel top 18 in cross-section taken from FIG. 5, through line A-A, and back panel 24. The cross sectional funnel shows one mode of the interior fastening devices for the four components of the funnel top 18 which are bolts 30, and receivers 31 for the bolts, which, as can be observed from the enlargement FIGS. 9 and 10. FIG. 9 shows two of the funnel components 32 being brought together to fasten with the bolt 30. It is contemplated within the scope of this invention to fasten the funnel components together using hinges for collapsibility purposes. It is also contemplated within the scope of this invention to use magnets 40 (FIG. 8A) to secure such funnel components. The funnel components 32 also have a hinge 40, that hinges the funnel components 32 to each other (See FIG. 8A).


As the trash bag 22 is filled, one can use the rod compactor set forth in FIGS. 12 and 13, wherein FIG. 12 illustrate a rod-like handle 33 which, for illustration purposes, threadedly connects to the platform 34 to form the rod compactor 35, is used to tamp down and compact the trash in the trash bag 22. Also shown in FIG. 14 is an illustration of a strap 37 to hold the trash bag 22 on the device 1 while trash bag 22 is being transported. Finally, there is an adjustable rake 38 that is capable of being mounted on the device 1.



FIG. 16 shows a device 1 of this invention fully loaded with accessories. Shown are water bottle 39, the rake 38, the platform 34, the rod compactor handle 33, the funnel 16 with panels 19 fully collapsed, and a strap 37.


Turning now to another embodiment of this invention there is shown in FIG. 17 a device 42 which has only a single rail 43 adjustment means as opposed to the double rail adjustment means of the first embodiment.


Thus, shown in FIG. 17 is the device 42(top portion shown), along with the funnel 47, the spring clips 49 that hold the trash bag, the vertical tube 45, and the single rail 48.


There are openings 52 in the single rail 48, and openings 53 in the vertical tube 45 and these align with each other. The single rail 48 and the vertical tube 45 are held in place by the insertion of a pin 51 through both holes. To adjust, the pin is removed and the funnel 16 with the single rail 48 is moved up or down to accommodate the desired height and then the pin 51 is re-inserted through the holes to hold them in place.


The devices 1 and 42 of this invention and its accessories are manufactured from aluminum, plastics, or carbon fiber impregnated resins, or a combination of them.


The devices of this invention, i.e., a lawn caddy is for receiving and transporting waste such as grass clippings, leaves, plant vegetation and compost waste. The lawn caddy transports yard waste from one location to another without heavy lifting. It is light and durable, having a maximum weight of 10 to 12 pounds with a capacity to hold 40 pounds or less of yard waste. By filling refuse bags and transporting waste to a curb side shortens time spent in cutting and cleaning lawns.
