Abstract

Systems and methods are provided for engaging with a user, the system for transporting the user forward from a first position to a second position. The system can include (A) a frame assembly including: (a) a left leg assembly and (b) a right leg assembly; (B) a Y-connection assembly, the Y-connection assembly connected to both an upper end of the left leg and an upper end of the right leg; (C) a track support assembly, the track support assembly being connected to, and supported under, the Y-connection assembly, the track support assembly extending in a transport direction and along the vertical axis; (D) a track assembly, the track assembly being supported by the track support assembly, and the track assembly including a track; (E) a trolley, the trolley movably positioned upon the track; and (F) a grab device.

What is claimed is: 
     
         1 . A system for engaging with a user, the system for transporting the user forward from a first position, in a transport direction, to a second position, the system comprising:
 a frame assembly including:
 a left leg assembly, the left leg having a left lower end and a left upper end, and the left lower end being secured upon a left supporting base, and 
 a right leg assembly, the right leg having a right lower end and a right upper end, and the right lower end being secured upon a right supporting base, and
 the left leg and the right leg being arranged on opposing sides about a vertical plane that is aligned with the transport direction; 
 
   a Y-connection assembly, the Y-connection assembly connected to both the upper end of the left leg and the upper end of the right leg;   a track support assembly, the track support assembly being connected to, and supported under, the Y-connection assembly, the track support assembly extending in the transport direction and along the vertical axis;   a track assembly, the track assembly being supported by the track support assembly, and the track assembly including a track;   a trolley, the trolley movably positioned upon the track so as to move from the first position to the second position; and   a grab device that is supported by the trolley, the grab device adapted for a user to engage with such grab device.   
     
     
         2 . The system of  claim 1 , wherein:
 the left leg is positioned at a first angle relative to the vertical plane, such that the left lower end is further away from the vertical plane than is the left upper end, the left upper end being forward of the left lower end; and   the right leg is positioned at a second angle relative to the vertical plane, such that the right lower end is further away from the vertical plane than is the right upper end, the right upper end being forward of the right lower end   
     
     
         3 . The system of  claim 2 , wherein:
 the first angle is between 1 degrees and 22 degrees; and   the second angle is between 1 degrees and 22 degrees.   
     
     
         4 . The system of  claim 2 , the first angle and the second angle are substantially the same, such substantially the same meaning within plus or minus 5 degrees from each other. 
     
     
         5 . The system of  claim 1 , the first leg assembly is constructed of a plurality of straight segments; and
 the first leg assembly is constructed of a plurality of further straight segments.   
     
     
         6 . The system of  claim 1 , the grab device is a rope. 
     
     
         7 . The system of  claim 1 , wherein:
 the left leg includes a left leg tube assembly that is constructed of at least one metal tube; and   the right leg includes a right leg tube assembly that is constructed of at least one metal tube.   
     
     
         8 . The system of  claim 1 , the system further including a retraction system, the retraction system retracting the trolley from the second position to the first position. 
     
     
         9 . The system of  claim 8 , the system further includes a weight, and the retraction system is gravity driven by the way, the weight being mechanically attached to the trolley via a pullback line. 
     
     
         10 . The system of  claim 9 , the retraction system including a retraction tube in which the weight is slidably disposed. 
     
     
         11 . The system of  claim 10 , the vertical plane passes through, and is aligned with, both the retraction tube and the track assembly, such that the retraction tube and the track assembly spatially define the orientation of the vertical plane, and are aligned with the transport direction. 
     
     
         12 . The system of  claim 1 ,
 the left supporting base includes a left base plate, the left base plate including fasteners for securement into a supporting surface, such as concrete; and   the right supporting base includes a right base plate, the right base plate including further fasteners for securement into the supporting surface.   
     
     
         13 . The system of  claim 1 , further including a retraction tube assembly that contains a weight, the weight mechanically coupled to the trolley via a retraction cable,
 the weight slidable in the retraction tube assembly so as to impose a force under gravity on the trolley.   
     
     
         14 . The system of  claim 13 , the retraction tube assembly is:
 attached at a top portion of the retraction tube assembly to the left leg assembly and the right leg assembly by a pair of struts; and   attached at a bottom portion of the retraction tube assembly to the left leg assembly and the right leg assembly by a cross-brace.
