As shown in FIGS. 9 and 10, the disclosed device may further include a handle 13 for carrying the device and an inclined or angled edge 14 at the distal end 24 of the device 10 for sliding the distal end of the device under a load to be carried by a hand truck.

[0035] FIGS. 11 and 12 illustrate another exemplary embodiment of the disclosed device 10 wherein the device generally includes a top surface 16; a first retaining member 26a including a first retaining bar 28a slidably coupled to the top surface 16, and a first retaining lip 29a extending from the first retaining bar, the first retaining lip defining a longitudinally extending bottom surface 17a; a first longitudinal channel 30a formed between the top surface 16 and the first retaining lip 29a; a second retaining member 26b including a second retaining bar 28b slidably coupled to the top surface 16, and a second retaining lip 29b extending from the second retaining bar, the second retaining lip defining a longitudinally extending bottom surface 17b; and a second longitudinal channel 30b formed between the top surface 16 and the second retaining lip 29b; wherein the first longitudinal channel 30a and the second longitudinal channel 30b define a hand truck nose receiving slot 11 for receiving and retaining the load supporting nose 19 of a conventional hand truck. In this embodiment, the first retaining bar 28a may be attached to the top surface 16 via a fastener 12 disposed in an aperture 32 formed in the first retaining bar, wherein the aperture 32 defines an elongated hole for receiving and retaining the fastener 12, the aperture being arranged and configured to provide for lateral movement of the first retaining bar by loosening the fastener 12, laterally sliding the first retaining bar 28a and then tightening the fastener 12 to fix the first retaining bar in a desired position. Additionally, in this embodiment, the second retaining bar 28a may be attached to the top surface 16 via a fastener 12 disposed in an aperture 32 formed in the second retaining bar, wherein the aperture 32 defines an elongated hole for receiving and retaining the fastener 12, the aperture being arranged and configured to provide for lateral movement of the second retaining bar by loosening the fastener 12, laterally sliding the second retaining bar 28a and then tightening the fastener 12 to fix the second retaining bar in a desired position. As illustrated in FIGS. 11 and 12, the first retaining bar and the second retaining bar may each include two apertures, each configured to receive one fastener. In other embodiments, the first retaining bar and the second retaining bar may each include one aperture or a plurality of apertures, each aperture being configured for receiving and retaining a fastener, said fastener being adjustable from a fastened position, which holds the retaining bar in a securely fastened position, to an adjustable position which allows the retaining bar to be moved laterally to a desired position until the fastener is adjusted back into a fastened position. Other embodiments are contemplated wherein the first retaining bar and the second retaining bar are slidably coupled to the top surface using other means known to those skilled in the art. In these embodiments, the position of the first retaining bar and the position of the second retaining bar are adjustable so that the device can be used on multiple hand trucks having differently sized load supporting noses.

[0036] In the exemplary embodiment shown in FIG. 13, the device further includes a first wing member 27a coupled to the device and a second wing member 27b coupled to the device, wherein the wing members are independently extendable from between the top and bottom surface of the device. The first wing member and the second wing member may be pivotably coupled to the device. Alternatively, the first wing member and the second wing member may be slidably coupled to the device. The wing members provide an even greater surface area to the disclosed device.

[0037] FIG. 14 illustrates an exemplary embodiment of the disclosed device 10 attached to the load supporting nose 19 of a conventional hand truck 18. The hand truck 18 comprises an elongated frame 20 having a handle 21 formed at an upper end thereof, a load supporting nose or platform 19 that extends perpendicularly from a lower end thereof, and a pair of wheels 22 connected to the frame by an axle 23.
