A mobile apparatus for assisting a person with limited mobility. The apparatus is also for developing a higher level of mobility in a person having low mobility. The person may be assisted by the apparatus when walking. The apparatus includes a seating surface resiliently mounted to provide partial body weight support to the person. A person using the mobility assist may grasp lateral handles disposed on the apparatus while walking or he/she may attempt to mobilize without the use of the lateral handles. Multiple elastic cords positioned to generate a lifting force that varies according to the number of elastic cords employed provide the degree of resilience in the seat. The degree of resilience may be adjusted in accordance with the relative collapse of the lower extremities of the person. As the walking ability of the person progresses, such lifting force may be reduced overtime by reducing the number of elastic cords employed.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A mobility assist device comprising: (a) a seat for supporting at least a portion of the weight of a person endeavoring to walk, said seat being located at a height above the ground whereby such person may remain in continuous contact with the ground; (b) a mobile support structure; (c) a rocker beam having a first end and a second end, said rocker beam being carried by a rocking beam pivot at a point intermediate said first end and said second end, said first end of said rocker beam being resiliently coupled to said mobile support structure through a resilient coupling member; and (d) said second end of said rocker beam carrying said seat; whereby said person endeavoring to walk may be assisted in walking by resting at least a portion of the weight of said person upon said seat while the seat is oriented such that said person endeavoring to walk faces away from the support structure and wherein the seat is oriented to provide that the legs of said person endeavoring to walk are substantially free in the user's forward direction from obstructions associated with the mobile support structure. 2. The mobility assist device as claimed in claim 1, further comprising: (e) at least one handle carried by the mobile support structure and positioned for grasping by said person endeavoring to walk. 3. The mobility assist device as claimed in claim 2, further comprising: (f) a seat axle positioned between said seat and said second end of said beam for pivotally supporting said seat. 4. The mobility assist device as claimed in claim 1, wherein said resilient coupling member comprises elastic cord means having a first cord end and a second cord end, and further having cord connection means disposed at each of said first cord end and said second cord end, said cord connections means being positioned for coupling said first cord end to said rocker beam and said second cord end to said mobile structure. 5. The mobility assist device as claimed in claim 4, wherein said elastic cord means comprises a plurality of detachable elastic cords, whereby the resilience of said resilient coupling member may be varied to allow the degree of support provided by the seat to said person endeavoring to walk to be varied in accordance with the number of said detachable elastic cords. 6. The mobility assist device as claimed in claim 1, wherein said mobile structure is mounted on roller supports, thereby to provide mobility to said mobile structure. 7. The mobility assist device as claimed in claim 6, wherein said mobility assist device further comprises a pair of articulated legs, each of said legs being pivotally mounted to said support structure about a substantially-vertical axis, thereby to permit deployment of said legs in a horizontal plane away from said person endeavoring to walk. 8. The mobility assist device as claimed in claim 7, further comprising a lock for locking said articulated legs in a fixed position with respect to said support structure. 9. The mobility assist device as claimed in claim 7 wherein, with the deployment of said legs away from said person endeavoring to walk, the legs of such person have a greater range of freedom in the direction lateral to the forward direction than when such legs are not so deployed. 10. A mobility assist device comprising: (a) a mobile support structure; (b) a beam which is pivotally connected at a pivot point to the mobile support structure; (c) a seat, resiliently supported by the beam, for supporting at least a portion of the weight of a person endeavoring to walk, said seat being located at a height above the ground whereby such person may remain in continuous contact with the ground and being positioned and oriented such that said person endeavoring to walk faces away from the support structure with the legs of said person being substantially free in the person's forward direction from obstructions associated with the mobile support structure whereby said person will be assisted in walking by resting at least a portion of the weight of said person upon said seat. 11. The mobility assist device as claimed in claim 10, comprising resilient means extending between the support structure and the beam to apply an upwardly-directed resilient force to the beam. 12. The mobility assist device as claimed in claim 10, wherein said mobile structure is mounted on roller supports, thereby to provide mobility to said mobile structure. 13. The mobility assist device as claimed in claim 10, wherein said mobility assist device further comprises a pair of articulated legs, each of said legs being pivotally mounted to said support structure about a substantially-vertical axis, thereby to permit deployment of said legs in a horizontal plane away from said person endeavoring to walk. 14. The mobility assist device as claimed in claim 13, further comprising a lock for locking said articulated legs in a fixed position with respect to said support structure. 15. The mobility assist device as claimed in claim 13 wherein, with the deployment of said legs away from said person endeavoring to walk, the legs of such person have a greater range of freedom in the direction lateral to the forward direction than when such legs are not so deployed.
