We claim: 1. A handle swivel assembly for a vehicle having a frame and a plurality of wheels comprising: a rear support base having a vertically oriented bearing support; a pivot pin disposed through the bearing support and pivotally coupled to the frame with a support structure thereby facilitating pivotal movement of the rear support base about a vertical axis relative to a front end of the rear support base; a first vertically oriented side plate coupled to the support base and having a first pivot link aperture disposed adjacent to an upper end thereof and a first handle pivot aperture forwardly disposed adjacent to a lower end thereof; and a generally horizontally oriented front support plate coupled to the side plate adjacent to the upper end thereof and having a substantially centrally disposed tie rod aperture for pivotal engagement with a tie rod that is operably coupled to a wheel for directional manipulation thereof. 2. The handle swivel assembly as claimed in claim 1 wherein the rear support base includes upper and lower horizontal plates vertically spaced relative to each other and integrally coupled to an upstanding wall disposed rearwardly relative to the side plate, each horizontal plate having a centrally disposed aperture in substantial vertical axial alignment relative to each other for receiving the bearing support. 3. The handle swivel assembly as claimed in claim 2 wherein the first side plate is coupled to the upper and lower horizontal plates. 4. The handle swivel assembly as claimed in claim 3 further comprising a second vertically oriented side plate coupled to the support base in transversely opposing relation to the first side plate and having a second pivot link aperture disposed adjacent to an upper end thereof in substantial horizontal axial alignment with the first pivot link aperture and a second handle pivot aperture forwardly disposed adjacent to a lower end thereof in substantial horizontal axial alignment with the first handle pivot aperture. 5. The handle swivel assembly as claimed in claim 4 wherein the front support plate is disposed between the first and second side plates thereby aligning the tie rod aperture in substantial equidistant relation to the first and second side plates. 6. The handle swivel assembly as claimed in claim 1 wherein the support structure includes a frame support fixedly secured to the frame and having a substantially horizontal channelway defined by two spaced apart, horizontally aligned sidewalls terminating on each end with a substantially vertically aligned frame bearing. 7. The handle swivel assembly as claimed in claim 6 wherein each sidewall includes a base pivot aperture disposed in substantial equidistant relation to the bearings and in substantial vertical axial alignment with each other. 8. The handle swivel assembly as claimed in claim 7 wherein the pivot pin is disposed through the pivot apertures and the bearing support thereby pivotally coupling the support base to the support structure. 9. The handle swivel assembly as claimed in claim 8 further comprising a wheel support having a generally outwardly extending spindle for operable engagement with a wheel and coupled to a base portion having inwardly extending upper and lower flanges, each flange having a flange bearing aperture in substantial vertical alignment relative to each other. 10. The handle swivel assembly as claimed in claim 9 wherein the upper flange includes a forwardly disposed tie rod support aperture for operably coupling the wheel support to the front support plate with the tie rod. 11. The handle swivel assembly as claimed in claim 10 wherein the wheel support is pivotally coupled to the support structure by disposing a pivot pin through the flange bearing apertures and the frame bearing. 12. The handle swivel assembly as claimed in claim 4 further comprising a pivot link having a horizontally aligned pivot link bearing disposed between the first and second side plates in substantial horizontal axial alignment with the first and second pivot link apertures. 13. The handle swivel assembly as claimed in claim 12 wherein the pivot link is pivotally coupled to the first and second side plates with a pivot link pin disposed through the first and second pivot link apertures and the pivot link bearing. 14. The handle swivel assembly as claimed in claim 13 wherein the pivot link includes a depending integral swing arm terminating with a substantially horizontal, transversely disposed cam bearing. 15. The handle swivel assembly as claimed in claim 14 further comprising a handle having a substantially elongated portion terminating with a horizontally oriented handle bearing disposed between two opposing, longitudinally extending cam plates, each cam plate having a cam structure disposed adjacent to an edge thereof. 16. The handle swivel assembly as claimed in claim 15 wherein the cam structure includes a substantially arcuate cam follower path with a retaining structure disposed in the approximate middle of the path. 17. The handle swivel assembly as claimed in claim 16 wherein the handle bearing is disposed between the first and second plates in substantial horizontal axial alignment with the first and second handle pivot apertures. 18. The handle swivel assembly as claimed in claim 17 wherein the handle is pivotally coupled to the first and second support plates with a handle pivot pin disposed through the first and second handle pivot apertures and the handle bearing. 19. The handle swivel assembly as claimed in claim 18 further comprising a brake control cable operably coupling the handle to a braking assembly that is operably coupled with a wheel and having a first terminal end with a cable connector having a vertically resisted portion with a centrally disposed cam pin aperture, the cable being coupled to the cam plate with a cam pin disposed through the cam pin aperture and the cam structure, wherein pivoting the handle about a horizontal axis from either a first position or second position causes a forwardly directed force in the cable to actuate the braking assembly to a non-braking condition.
