Said hollow geometrically shaped body or alternatively referenced as chassis frame or chassis body 101 having a front 106, rear 107, top 108, bottom 109, right 110, and left side 111 surfaces. Said top 108, bottom 109, right 110, and left 111 sides surfaces forming the length of the device which is longer than its said cross-sectional width, in total having a substantially rectangular shape. The length of said chassis frame may be any length but is preferably 6.5 feet long (78 inches) or alternatively a preferred length of under 8 feet long. The height of side surfaces may be up to 36 inches but is preferably 11 inches tall according to the preferred embodiment of this invention. Said front 106, rear 107, top 108, bottom 109, right 110, and left 111 side surfaces having an external surface 112 facing the external environment and an internal surface facing the internal space within said hollow geometrically shaped body 101. The width of said top 108 and bottom 109 surfaces may be up to 36 inches wide but is preferably 13 inches wide according to the preferred embodiment of this invention. Said hollow geometrically shaped body 101, comprising said front 106, rear 107, top 108, bottom 109, right 110, and left 111 side surfaces of this preferred embodiment comprising the chassis body (or alternatively referred to as the chassis frame) 101 of this invention.
(19) Said rotatable resting element 102 comprising a planar panel 115 of substantially similar cross-sectional width as said top surface 108 of said chassis frame 101 and rearwardly disposed within the rear half along the length of said chassis frame 101. Said planar panel 115 of said resting element 102 having a length that is greater than its width. Said length comprising a left 116 and right side 117 parallel to the left 111 and right 110 sides of said chassis frame. Said planar panel 115 terminating at a top 118 and bottom 119 side. Said top side 118 of said planar panel element 115 terminating beyond the rear end 107 of said chassis frame 101 while the bottom end 119 terminates within the rearward half of said top surface of said chassis frame 101. A rotating mechanism comprising a bar 120 sleeved through perforations 121 along the left 111 and right 110 side surfaces of said chassis frame 101.

Said linear actuator 402 comprising a length of threaded screw with any preferred length between one (1) to 5 (five) feet, said linear actuator 402 being disposed centrally along the front half of said chassis frame 404. Said linear actuator 302 having a first end 303 closer to the front end of said chassis frame and a second end farther 304 away from the front end of said chassis frame. Said linear actuator 402 connected to a motor drive 401 wherein said motor drive 401 is electrically driven to rotate in two opposing directions by threaded screw element. The driven movement of said motor drive 401 causing said threaded screw element 402 to rotate in either of two opposing direction. A carriage 301 is detachably connected to said linear actuator 402 at the lower end of said carriage 301. Said connection may be by threaded screw and bolt connection, hook style connection, clip style connection, pneumatic style connection, or any known means for a removable and secure positioning of said carriage 301 on said linear actuator 302 wherein said carriage is rollably seated on either said two parallel guide tracks 305. The top surface 306 of said carriage element 301 is further attachable to optional tools by detachable connection means (i.e. threaded screw means, clamping means, hook means, etc.).

To facilitate smooth traversal along the length of said chassis frame and threaded screw drive of said linear actuator, a cross-bar 310 is fixedly attached at the rearward end of said two parallel guide track 305 across the cross-section of said chassis frame 309 to maintain the two parallel guide tracks 305 in fixed parallel position. This is especially important in lieu of high amount of usage by multiple different users or alternatively shifting weight of the user seated thereon, which could throw off parallel alignment of the guide tracks 305. A loss of parallel alignment of the two parallel guide tracks 305 would otherwise cause the traversal movement of the rollers along the guide track to seize. The cross-bar 310 in this case would serve to hold the two parallel guide tracks 305 in fixed parallel position in spite of pressures thereon and will further serve to block continued traversal of said carriage 301 beyond and past the terminal end of said two parallel guide tracks 305.
