Abstract
A stair transport device (1) having a planar top platform (2), two legs (3) connected to a front end (17) on each side (20) and a cross bar (4) with T-ends (23) connecting the two legs. Each leg has two sections (3 a & 3 b) slidably connected with apertures into which a pin can be inserted to adjust the height thereof. The back end (18) end of the top platform can be placed over a top stair of a plurality of stairs to provide a horizontal platform level with the guide wheels (10) of a gurney (8) for transport of medical patients and other items.
Description
- This invention relates to transport platforms and more particularly a platform that provides a level surface over stairs for transporting medical patients and other items.
- Stairs can present a major obstacle for anyone who desires to transport anything up them particularly anything on wheels, such as a wheeled gurney used to transport medical patients. When faced with such an obstacle, most often a patient has to be removed from a wheeled gurney and carried up the stairs by one or more persons, particularly if a patient is heavy. When doing so there is a risk that a patient can be dropped and injured or condition worsened by not being maintained in a horizontal position. Also, as medical transport vans are normally operated by a single worker, often another person must be called to assist to carry a person up stairs, thereby incurring additional labor and costs.
- Therefore, a need exists for a transport platform that can be used to transport items on wheels over stairs that is adjustable to accommodate varying number of stairs and is collapsible for east storage and portability.
- The primary object of the present invention is to provide a platform device for that allows persons and other items to be easily and safely transported over stairs.
- Another object of the present invention is to provide such a device that is adjustable in height to accommodate a range of stair levels.
- An additional object of the present invention is to provide a device that is collapsible for convenient handling and storage.
- The present invention fulfills the above and other objects by providing a stair transport device having three major components—a planar platform having a top, bottom, two sides, a front end and a rear end; a leg attached to each side at the front end of the planar platform; and a cross support bar connecting the two legs, said cross bar having a T at each end which the legs pass through. Preferably, each leg has a top section and a bottom section, each section having a plurality of apertures, the bottom section having a cross section less than the cross section of the upper section such that the lower section can slide up or down into the top section. The T ends of cross support section each have at least one aperture with a pull pin for insertion into the at least one aperture in each T end and the top and bottom sections to adjust a height of the platform. The platform preferably has raised edges on the two sides thereof to guide wheeled transport devices on the platform. The stair platform device is collapsible as the legs are rotatably attached to the platform by a connection plate having an aperture into which a pin can be inserted to maintain the legs in a vertical and perpendicular position relative to the platform during use and to maintain the legs in a folded position when the platform is in a collapsed mode for handling and storage.
- The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.

- With reference to the drawing figures,
FIG. 1 illustrates a perspective view of thestair transport device 1 of the present invention in use. Thestair transport device 1 has three essential component: one, a planartop platform 2 having twosides 20, afront end 17, aback end 18 and a bottom 16; two, a pair oflegs 3 connected on eachside 20 at thefront 17 of theplatform 2 by aconnection plate 19; and three, across bar 4 connecting thelegs 3 at a desired height. When a wheeled object, like agurney 8 as shown inFIG. 1 , carrying apatient 9 over aground surface 22 onground surface wheels 11 approaches theplatform 2 withupper guide wheels 10, thegurney ground wheels 11 fold up compact under thegurney 8 and thegurney 8 is pushed over and across theplatform 2. Theplatform 2 preferably has two raisedrails 5 on each side to prevent theguide wheels 10 ofgurney 8 from falling off thesides 20 of theplatform 2. Additionally, theplatform 2 may have non-skid tape or material 7 on top to provide traction and deter slippage during use. Thelegs 3 haveapertures 13 along the length thereof to allow pins to be placed for height adjustment purposes. Thelegs 3 preferably have arubber base 12 to provide traction for thelegs 3 on aground surface 22. As shown in use inFIG. 1 theback end 18 ofplatform 2 is placed over thetop step 24 to provide a level runway with thegurney guide wheels 10. - As also illustrated in
FIG. 2 , thelegs 3 consist of two sections, atop section 3 a and abottom section 3 b. The cross section of thelower leg section 3 b is less than the cross section of theupper leg section 3 a so thelower section 3 b slidably fits into theupper section 3 a so it can be moved up or down within theupper section 3 a depending on the height of thestairs 21 being transported over so that theplatform 2 is level over a top stair. Thecross bar 4 has T ends which encompass thelegs 3 andapertures 13 into which pull pins 6 b can be inserted to affix thelegs 3 at a desired height to match the height of thestairs 21. Thelegs 3 andplatform 2 are maintained in a perpendicular use position as shown inFIGS. 1 and 2 bytop pull pin 6 a inserted through an aperture in theconnection plate 19 andtop section 3 a of thelegs 3. - Referring now to
FIGS. 3 and 4 , side and top views of thetransport device 1 of the present invention, respectively, are illustrated showing the component discussed above in relation toFIGS. 1 and 2 . -
FIGS. 5 and 6 illustrate thetransport device 1 when it is positioned in a collapsed mode for easy handling and storage when not in use. Thetransport device 1 is placed in a collapsed mode by simply pulling theupper pull pin 6 a at the top of eachleg 3 and rotating eachleg 3 upward in line with theplatform 2 and then reinserting thepin 6 a to secure the device in the collapsed mode.FIG. 5 also more clearly shows theplatform holding bolts 15 andleg holding bolts 14 in theconnection plate 19. - 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.
- 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.
