[0044] With reference to the drawing figures, FIG. 1 illustrates a perspective view of the stair transport device 1 of the present invention in use. The stair transport device 1 has three essential component: one, a planar top platform 2 having two sides 20, a front end 17, a back end 18 and a bottom 16; two, a pair of legs 3 connected on each side 20 at the front 17 of the platform 2 by a connection plate 19; and three, a cross bar 4 connecting the legs 3 at a desired height. When a wheeled object, like a gurney 8 as shown in FIG. 1, carrying a patient 9 over a ground surface 22 on ground surface wheels 11 approaches the platform 2 with upper guide wheels 10, the gurney ground wheels 11 fold up compact under the gurney 8 and the gurney 8 is pushed over and across the platform 2. The platform 2 preferably has two raised rails 5 on each side to prevent the guide wheels 10 of gurney 8 from falling off the sides 20 of the platform 2. Additionally, the platform 2 may have non-skid tape or material 7 on top to provide traction and deter slippage during use. The legs 3 have apertures 13 along the length thereof to allow pins to be placed for height adjustment purposes. The legs 3 preferably have a rubber base 12 to provide traction for the legs 3 on a ground surface 22. As shown in use in FIG. 1 the back end 18 of platform 2 is placed over the top step 24 to provide a level runway with the gurney guide wheels 10.

[0045] As also illustrated in FIG. 2, the legs 3 consist of two sections, a top section 3a and a bottom section 3b. The cross section of the lower leg section 3b is less than the cross section of the upper leg section 3a so the lower section 3b slidably fits into the upper section 3a so it can be moved up or down within the upper section 3a depending on the height of the stairs 21 being transported over so that the platform 2 is level over a top stair. The cross bar 4 has T ends which encompass the legs 3 and apertures 13 into which pull pins 6b can be inserted to affix the legs 3 at a desired height to match the height of the stairs 21. The legs 3 and platform 2 are maintained in a perpendicular use position as shown in FIGS. 1 and 2 by top pull pin 6a inserted through an aperture in the connection plate 19 and top section 3a of the legs 3.

[0046] Referring now to FIGS. 3 and 4, side and top views of the transport device 1 of the present invention, respectively, are illustrated showing the component discussed above in relation to FIGS. 1 and 2.

[0047] FIGS. 5 and 6 illustrate the transport device 1 when it is positioned in a collapsed mode for easy handling and storage when not in use. The transport device 1 is placed in a collapsed mode by simply pulling the upper pull pin 6a at the top of each leg 3 and rotating each leg 3 upward in line with the platform 2 and then reinserting the pin 6a to secure the device in the collapsed mode. FIG. 5 also more clearly shows the platform holding bolts 15 and leg holding bolts 14 in the connection plate 19.

[0048] It is to be understood that while a preferred embodiment of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown.

[0049] It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and drawings.
