DETAILED DESCRIPTION OF THE INVENTION

(7) The present invention relates to the field of sandbagging, and more particularly, to a sandbagging attachment (hereinafter attachment) to a conventional two-wheel dolly of the type also known as a hand truck, two wheeler, stack truck, trundler, box cart, sack barrow, cart, etc. Such a dolly has a small platform, onto which the load is placed. Upon loading, the dolly is tilted back as a first-class lever for placing the load into a position stable on the platform and then tilted down at the place of destination for unloading. The attachment of the invention makes it possible to simply secure this device to any standard tiltable two-wheeler, secure a bag on it, fill the bag with sand without use of shovels, and deliver the filled bag to a required location. All these operations are accomplished without use of manual labor, except for transporting the dolly and removal of the filled bag from the latter.

(8) The attachment of the invention, which in general is designated by reference numeral 20, is shown in an assembled state and in a position secured to a dolly 22 in FIG. 1, which is a three-dimensional view. It can be a standard tiltable two-wheeler, e.g., a Loop Handle Steel Hand Truck with Rubber Wheels Model H-1786, purchasable from Pleasant Prairie, Wis. The dolly 22 has chasses on two wheels 22a, 22b, a load platform 22c, and a frame 22d with a loop-like handle 22e. The dolly of this type is given only as an example and many other dollies are suitable for the purposes of the invention. In any case, the dolly 22 is not a subject of the invention and is beyond the invention scope. It is important, however, that the dolly is a tiltable two-wheeler that can be tilted back as a first-class lever for placing the load into a position stable on the platform and then tilted down at the place of destination for unloading.

(9) The attachment 20 has a connectable/disconnectable dolly connection member 24 shown in more details in FIG. 2, which is a partial three-dimensional view of the attachment 20.

(10) The connectable/disconnectable dolly connection member 24 is formed by a pair of plates, i.e., a front plate 24a and a rear plate 24b, with at least two pairs of aligned openings 24c and 24d (the openings of the front plate 24a are shown by broken lines and not designated) and at least two fastening devices 26a and 26b for securing the connectable/disconnectable dolly connection member 24 to the dolly 20 by sandwiching the lower part of the dolly frame member 22d between the front plate 24a and the rear plate 24b in their connected state shown in FIG. 1. The fastening devices are shown as bolts 26a1, 26b1 and nuts 26a2, 26b2. It is understood that for clamping the attachment connection member 24 to the dolly frame member 22d, the nuts 26a2 and 26b2 are to be threaded onto the ends of the bolts 26a, 26b1 protruding outward through the respective openings of the front plate 24a and tightened on the protruding ends.

(11) Attached, e.g., welded, to the upper face of the rear plate 24b are rotary bearing portions 28a and 28b installed on the left and right sides of the plate 24b. The rotary bearing portions 28a and 28b have aligned openings (only one opening 30a is shown and designated) for insertion of an axle 32 through both openings and through a tubular sleeve 34, which is, as shown in FIG. 2, is placed between the rotary bearing portions 28a and 28b and constitutes a rotationally supported part. The axle 32 is fixed in the rotary bearing portions 28a and 28b by L-shaped pins 36a and 36b through openings 38a and 38b, respectively. The L-shaped pins 36a and 36b are shown as examples, and other means can be used for securing the axle 32.

(12) The sleeve 34 has a sliding fit on the fixed axle 32 so that the tubular sleeve 34 is installed on the axle 32 rotationally.

(13) A foot pedal 40 is attached to the sleeve 34 in a radially outward direction. To prevent contact of the pedal 40 with the front plate 24a, when the pedal is pushed down for rotation in the counterclockwise direction, the front plate 24a has a height H1 lower than the height H2 of the rear plate 24b.

(14) A pair of scoop holding members 42a and 42b, which rigidly support a scoop 44, is rigidly attached, e.g., by welding, at one ends to the scoop 44. At the opposite ends the scoop holding members 42a and 42b are attached to the tubular sleeve 34. The scoop holding members 42a and 42b, and hence the scoop 40, also extend radially outward from the sleeve 34 but are attached to the outer surface of the scoop 44 in an intermediate position between the open front end and the open rear end of the scoop. Angularly, the scoop-holding members 42a and 42b are shifted from the position of the pedal 40 to provide convenient manipulation of the scoop by using the pedal.

(15) The scoop 44 itself is defined by sidewalls 44a, 44b and a bottom plate 44c. The scoop 44 has an open front end 44d and an open rear end 44e (FIG. 2) for forming a through passage between the front end and the rear end and thus for passing a scoopable material, such as sand, grain, or the like, through the scoop to a bag B which can be fitted onto the scoop from the open rear end. For this purpose, gaps G1 and G2 are formed between the sidewalls 44a, 44b and the scoop-holding members 42a and 42b. The front end of the bag is inserted into the gaps G1 and G2.

(16) The front end of the bag is secured to the sides of the scoop 44 by the bag securing devices for keeping the bag open during the scooping operation. For this purpose a small bag-securing device 46a is used (a similar bag-securing device not seen in the drawings is located on the other side 44b). The securing device may be represented, e.g., by toggle clamps located near said intermediate positions and attached to the outer surfaces of the sidewalls 44a and 44b (FIG. 1). An example of such a securing device is a toggle clamp E-TING New 4PCS Hand Tool Toggle Clamp 201A Antislip Red Horizontal Clamp 201-A, available from Amazon.

(17) For preventing sticking of the edge of the open front end 44d of the scoop 44 into the ground G and for scooping the sand S only, the scoop 44 has on the outer side of the bottom plate 44c near the open front end an arc-shaped slider 48. The slider 48 may extend over the entire width of the front edge of the scoop 44 or may consist of two arc-shaped portions installed on the sides of the bottom plate.

(18) An operation of the attachment 22 will now be described with reference to FIGS. 3A, 3B, and 3C.

(19) If the attachment 22 is stored separately from the dolly 20, it should first be firmly secured to the dolly by clamping the front and rear plates 24a and 24b to the lower part of the frame member 22d of the dolly 20. This is done by sandwiching the lower part of the frame member 22d between the plates 24a and 24b and tightening the nuts 26a2 and 26b2 on the ends of the bolts 26a1 and 26b1 inserted into and protruding from the openings 24c and 24d. The plates are secured in positions shown in FIGS. 1 and 2 so that the scoop 44 extends in a forward direction of the dolly. In this state, the foot pedal is oriented in a position convenient for pressing by foot.

(20) A bag B is fitted onto the scoop 44 from the side of the rear open end 44e and guided further over the scoop through the gaps G1 and G2 to the area where the front end of the bag B can be clamped to the outer surfaces of the sidewalls 44a and 44b by toggle clamps, such as the clamp 46a (FIG. 2). This is necessary to keep the bag in an open state during scooping. The attachment is now ready for use.

(21) In FIG. 3A, the attachment 22 is shown in a position for scooping a portion of sand S from a pile P. A user (not shown) pushes the dolly 20, and hence the scoop 44, forward for digging the sand. The bag is filled to a certain level leaving the upper part of the bag free for tying it up.

(22) Next, upon completion of the filling operation, the user pushes down on the pedal for turning the scoop 44 with the filled bag B to a counterclockwise direction. Under its own weight, the filled bag goes down until it rests on tubular sleeve 34. This condition is shown in FIG. 3B. The user then raises the bag and places it onto the load platform 22c of the dolly. In this position, which is shown in FIG. 3C, the dolly 20 may transport the filled bag to the destination without a risk of rollover.

(23) Although the attachment of the invention was shown and described with reference to specific embodiments, it is understood that these embodiments cannot be considered as limitative and that any changes and modifications are possible without deviation from the scope of the attached claims. For example, the attachment may be used for bagging grains, wooden chips, or any other bulk and scoopable materials. The connection member can be secured to the frame of the dolly by means other than threaded fasteners. Hooks can be used for securing the upper end of the bag to the scoop. The pedal may be removable. The axle may remain loose in the bearing supports. Additional bag security means such as a chain or rope may be used for fixing the bag during the transportation.
