BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to spine boards and more specifically it relates to a wheeled attachment system for efficiently attaching to a spine board to allow the spine board to be easily maneuvered over various surfaces (e.g. flat surfaces, stairs, etc.).
2. Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Spine boards have been in use for years within various fields (e.g. medical, etc.). Spine boards are typically utilized for the immobilization and transportation of patients with suspected neck or spinal injuries. Spine boards are also typically comprised of a hard material, such as wood or plastic to prevent the board from bending while utilizing the present invention.
It is generally necessary when utilizing spine boards for at least two people to carry the board and patient upon the board. When carrying the patient and spine board in hard to maneuver places, such as stairs, one person generally has to walk backward while carrying their end of the board. This can be hazardous for the patient along with the individual carrying the board.
Attempts have been made to attach wheels to an end of the board; however while the wheels may provide easy transportation among flat surfaces they generally are not efficiently maneuverable among stairs. Because of the inherent problems with the related art, there is a need for a new and improved wheeled attachment system for efficiently attaching to a spine board to allow the spine board to be easily maneuvered over various surfaces (e.g. flat surfaces, stairs, etc.).

F. Operation of Present Invention
As illustrated in the embodiment of FIG. 1, the strap 62 is first loosened and the side supports 70 are angled in a manner to conform to the sides of the spine board 12 adjacent the end of the spine board 12 that the present invention is to be attached to. The present invention is then positioned upon the end of the spine board 12 ensuring the retaining portions 32, 42 of the center support 40 and outer supports 30 are positioned upon the end of the spine board 12. The outer supports 30 may need to be slidably adjusted so the side supports 70 are positioned tight against each of the sides of the spine board 12. The strap 62 is now ensured to be properly wrapped around the spine board 12 and through the loop member 72 of the side support(s) 70. The strap 62 is now tightened and the buckle 63 fastener thus securing the present invention to the spine board 12.
As illustrated in the new embodiment of FIGS. 8 through 12, the side supports 70 are pivoted outwards via the slight amount of “play” (i.e. space 78) between the inner receiver opening 77 and the center sleeve 24 surrounding the shaft 22 as illustrated in FIG. 13. The strap 62 may also be loosely strung through the slots 75 of the side supports 70. The spine board 12 is now slid within the rectangular shaped cavity 79 formed between the side supports 70 and through the loop formed by the strap 62. Once the spine board 12 is positioned firmly against the footrest 45 or the center support 40 and within the cavity 79, the side supports 70 may be pivoted inwardly toward and against the spine board 12. The strap 62 may then be cinched tightly thus tightening the side supports 70 further against the spine board 12. A pair of retaining straps 66 may then be secured within the side openings 13 of the spine board 12 and the outer loop member 76 of the side supports 70 and tightened accordingly.
When utilizing the present invention the wheels 56 are able to freely roll, wherein an operator would push or pull the opposing end of the spine board 12 than the present invention is attached. When pulling or pushing the spine board 12 and attached present invention down the stairs 19, the wheels 56 and the hub 50 freely rotate thus allowing the spine board 12 to crawl down or up the stairs 19 in a smooth manner.
