ABSTRACT:
A device supported by a ground surface and a structure for at least one of elevating and descending a user. The device includes a first guide rail having a first channel extending along a length thereof and a second guide rail having a second channel extending along the length thereof. At least one connector connects the first guide rail with the second guide rail at a predetermined location along a length thereof so that said first channel and said second channel face inwards towards each other. A platform for supporting the user having a predetermined amount of weight is connected within each of the first and second channels and between the first guide rail and second guide rail. The device further includes means for moving the platform along the length of each of the first channel and the second channel. Upon the moving means being engaged by a user, the platform is moved distally towards at least one of a first end of the guide rails and a second end of the guide rails opposite the first end thereby moving the user therealong.
