Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
245 words
In a vehicle for developing a driver''s coordination of various controls and capable of motion about the longitudinal, transverse, and vertical axes thereof, said vehicle comprising (a) a frame including a longitudinal member and a transverse member, (b) at least three individually controllable surface engaging members connected to said frame, (c) at least one seat disposed between two of said surface engaging members and fixed with respect to said frame, (d) at least one control lever means for raising and lowering at least one of said surface engaging members with respect to said frame for effecting a turning of said vehicle about at least one of said axes, (e) steering means connected to at least one of said surface engaging members for causing said surface engaging member to rotate about a vertical axis to effect a motion of said vehicle about said vertical axis when moving, the improvement wherein: said control lever means comprises a single rigid bar having one free end constituting a hand grip and having a second free end pivotally connected at one point, directly to one of said surface engaging members, and wherein said bar is pivotally connected to said transverse frame member by means of a bearing connected to said bar at a point thereon closer to said surface engaging member end than to said hand grip end, and further wherein said bar is free to pivot all the way into contact with said surface engaging member on the surface.
Claim 2
Dependent Claim
245 words
In a vehicle for developing a driver''s coordination of various controls and capable of motion about the longitudinal, transverse, and vertical axes thereof, said vehicle comprising (a) a frame including a longitudinal member and a transverse member, (b) at least three individually controllable surface engaging members connected to said frame, (c) at least one seat disposed between two of said surface engaging members and fixed with respect to said frame, (d) at least one control lever means for raising and lowering at least one of said surface engaging members with respect to said frame for effecting a turning of said vehicle about at least one of said axes, (e) steering means connected to at least one of said surface engaging members for causing said surface engaging member to rotate about a vertical axis to effect a motion of said vehicle about said vertical axis when moving, the improvement wherein: said control lever means comprises a single rigid bar having one free end constituting a hand grip and having a second free end pivotally connected at one point, directly to one of said surface engaging members, and wherein said bar is pivotally connected to said transverse frame member by means of a bearing connected to said bar at a point thereon closer to said surface engaging member end than to said hand grip end, and further wherein said bar is free to pivot all the way into contact with said surface engaging member on the surface.
Claim 3
Dependent Claim
66 words
A vehicle in accordance with claim 1 wherein said steering means comprises: a foot lever pivotally connected to said longitudinal frame member; means connected to said foot lever for causing said surface engaging means to turn in a direction opposite to the direction of pivot of said foot pedal; and means therein for limiting the angular range through which said surface engaging member may be turned.
Claim 4
Dependent Claim
109 words
A vehicle in accordance with claim 1, wherein said steering means comprises: a foot lever having a lug integrally attached thereto; a first pivot pin pivotally connecting said lug to said frame; a connecting member connected to said surface engaging means at one end and pivotally connected to said frame at the other end; a slotted plate fixedly connected to said connecting member and having a slot therein; a second pivot pin pivotally connected to said lug and slidingly connected to said slotted plate within said slot; whereby the length of angular motion of the slotted plate about said pivot point is limited by the length of said slot.
Claim 5
Dependent Claim
14 words
A vehicle in accordance with claim 1 wherein said surface engaging members are skids.
Claim 6
Dependent Claim
14 words
A vehicle in accordance with claim 1 wherein said surface engaging members are wheels.
Claim 7
Dependent Claim
14 words
A vehicle in accordance with claim 1 wherein said surface engaging members are floats.
