An adjustable handcart that provides a horizontal platform for transporting items of cargo or people, such as a patient immobilized upon a spine board. The handcart includes a platform and a platform extension slidably connected at one end and held in place by a lock mechanism. A wheel assembly extends downwardly from the platform to support the platform in a substantially horizontal position off the ground. On the end opposite the platform extension, handles are attached. The handles may be detachable and/or rotatable (to facilitate folding), thereby allowing the handcart to be easily cleaned, stacked, or compacted as needed.

What is claimed is: 1. A handcart, comprising: a platform having a first end and a second end, a platform extension slidably connected to said first end of said platform in coaxial alignment therewith, a lock means for holding said platform extension in a predetermined position, a wheel assembly attached proximally to said first end of the platform and extending downwardly a predetermined distance from said platform, a stand attached proximally to said second end of the platform and extending downwardly from said platform substantially the same predetermined distance as said wheel assembly; and handle means attached to said second end of said platform, wherein said wheel assembly and said stand are spaced apart such that, when said handcart is positioned upside down, a wheel assembly of a second handcart of the invention is receivable between the stand and said second end, thereby positioning said handcart in substantially horizontal stackable arrangement with said second handcart. 2. The handcart of claim 1, wherein said platform further includes at least one clamp assembly disposed upon a top side thereof. 3. The handcart of claim 1, wherein said platform extension further includes a stop plate extending from a connecting end thereof. 4. The handcart of claim 1, wherein said handle means are rotatable in a plane defined by said platform. 5. The handcart of claim 1, wherein said handle means are removable. 6. The handcart of claim 1, wherein said lock means comprises a pull pin. 7. The handcart of claim 1, wherein said platform further includes a stop tab extending from a top side proximate to said second end. 8. The handcart of claim 1, further including a spine board disposed upon a top side of said platform. 9. A handcart, comprising: a platform of parallel spaced-apart rails, said rails each having a first end and a second end, a platform extension slidably connected in coaxial alignment to said first end of each rail of said platform, said platform extension held in a predetermined position by a lock means, a lock means for holding said platform extension in a predetermined position, a wheel assembly attached proximally to said first end of the platform and extending downwardly a predetermined distance from said platform, a stand attached proximally to said second end of the platform and extending downwardly from said platform substantially the same predetermined distance as said wheel assembly; and handle means attached to said second end of said platform, wherein said wheel assembly and said stand are spaced apart such that, when said handcart is positioned upside down, a wheel assembly of a second handcart of the invention is receivable between the stand and said second end, thereby positioning said handcart in substantially horizontal stackable arrangement with said second handcart. 10. The handcart of claim 9, wherein said platform further includes at least one clamp assembly disposed upon a top side thereof. 11. The handcart of claim 9, wherein said platform extension further includes a stop plate extending from a connecting end thereof. 12. The handcart of claim 9, wherein said handle means are rotatable in a plane defined by said platform. 13. The handcart of claim 9, wherein said handle means are removable. 14. The handcart of claim 9, wherein said lock means comprises a pull pin. 15. The handcart of claim 9, wherein said platform further includes a stop tab extending from a top side proximate to said second end. 16. The handcart of claim 15, wherein said handle means rotate and engage said stop tab upon application of a lifting force to said handle means. 17. The handcart of claim 9, further including a spine board disposed upon a top side of said platform. 18. A handcart, comprising: a platform having a first end and a second end, a wheel assembly attached proximally to said first end of the platform and extending downwardly a predetermined distance from said platform, a stand attached proximally to said second end of the platform and extending downwardly from said platform substantially the same predetermined distance as said wheel assembly; and handle means attached to said second end of said platform, wherein said wheel assembly and said stand are spaced apart such that, when said handcart is positioned upside down, a wheel assembly of a second handcart of the invention is receivable between the stand and said second end, thereby positioning said handcart in substantially horizontal stackable arrangement with said second handcart.
