A vehicle designed specifically to pull persons standing upright on roller skates, ice skates, skis etc. The invention can be configured to operate on any surface and comprises of an engine driving a wheel or track, connected through a frame to a body pad complete with shoulder and arm supports. The body pad can pivot independently of the frame. Handgrip controls contain actuators for acceleration and braking. The purpose of the invention being to produce a vehicle that allows the operator to be in complete control and to be able to make abrupt turns, accelerate or decelerate, all in an efficient manner. The operator of the vehicle remains in close contact with the vehicle by means of a torso clamp or belt securing the operator to a body pad. The torso clamp or belt can be adjusted to automatically release and disengage the operator in the event of a fall. Direction changes are accomplished by pulling against one of the handgrips, which has the effect of causing the body pad to pivot on its axis, effecting a change in the direction of travel. More pronounced turns require a combination of pivoting the body pad while shifting body weight and leaning in the desired direction of travel. Other versions of the vehicle have a complete crash guard around the operator and a wheel or ski joined directly of the body pad allowing its use without the need to wear skates, skis, etc.

A modular bridge apparatus, comprising: a) left and right trusses; b) each truss having a top and bottom, a plurality of upper longitudinal chord members defining the top and a plurality of lower longitudinal chord members defining the bottom; c) a plurality of laterally extending beams that extend between the left and right trusses; d) a plurality of inclined beams that span between and directly connect to upper and lower chord members, and include at least some diagonally extending beams; e) a plurality of joints that connect beams together, including upper joints that connect one or more upper longitudinal chord members to an inclined beam and lower joints that connect one or more lower longitudinal beams to an inclined beam and at least one diagonal beam; f) a plurality of transverse horizontal beams extending between the left and right trusses, connecting thereto at intermediate joints above the elevation of the lower joints, some of the transverse horizontal beams being longer beams that extend laterally beyond the longitudinal chord members; g) a plurality of diagonally and laterally extending inclined beams that each extend between an end portion of a laterally extending horizontal beam and a truss at a position near an upper chord member; and h) an expanse of bridge decking that is attached to the truss at the transverse horizontal beams. 23. The modular bridge apparatus of claim 22 wherein there are a first plurality of laterally extending deck beams of a first shorter length and a second plurality of longer laterally extending deck beams of a second length. 24. The modular bridge apparatus of claim 22 wherein there are a plurality of said diagonally and laterally extending inclined beams. 25. The modular bridge apparatus of claim 22 wherein the joints include bolted connections. 26. The modular bridge apparatus of claim 22 wherein the bridge decking is positioned at an elevation that is spaced above the lower longitudinal chord members. 27. The modular bridge apparatus of claim 22 wherein the decking has a width and at least some of the transverse beams extend transversely beyond the width of the decking. 28. The modular bridge apparatus of claim 22 wherein the decking has left and right sides, and at least some of the transverse deck beams extend transversely to the sides of the decking and other of the transverse beams extend transversely beyond the width of the decking and beyond both sides of the decking. 29. The modular bridge apparatus of claim 22 wherein the diagonally and laterally extending beams are provided on both sides of the decking. 30. The modular bridge of claim 28 wherein the deck beams include longer deck beams that have end portions, both end portions of a longer deck beam having one of said diagonally and laterally extending inclined beams attached thereto.
