Abstract

Abstract A human powered mechanism for propelling a wheeled land vehicle, a water vehicle (a boat or hydroplane) using either a water screw or a jet of water or an ultra-light aircraft with an air screw. The mechanism can utilize either arm or leg muscles or preferably, both arms and legs extending and retracting in a manner similar to walking or running as performed from a semi-recumbent position. Steering or other critical control is accomplished through another mechanism which is guided by the appropriate movement of the operator's head. The operators feet are placed on pedals which are attached to swinging members which pivot in a bearing at the upper end. The operator's hands grasp leverage arms which are cantilevered, the distal ends of which are attached to the same push-pull connecting rods as the above mentioned swinging members with foot pedals attached.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 128 words
In a human powered vehicle including a steering system for regulating vehicle direction, a head actuated steering control apparatus comprising: a steering linkage assembly for controlling said steering system; and a head engaging member for enclosing an operator's head, said head engaging member including an actuating element for selectively linking said head engaging member and said steering linkage assembly in response to a tilting of said head engaging member, a linking of said head engaging member and said steering linkage assembly in response to the tilting of said head engaging member resulting in a change in said vehicle direction, said actuating element further preventing a linking of said head engaging member and said steering linkage assembly in response to a lateral, horizontal rotation of said head engaging member.
Claim 2
Dependent Claim 128 words
In a human powered vehicle including a steering system for regulating vehicle direction, a head actuated steering control apparatus comprising: a steering linkage assembly for controlling said steering system; and a head engaging member for enclosing an operator's head, said head engaging member including an actuating element for selectively linking said head engaging member and said steering linkage assembly in response to a tilting of said head engaging member, a linking of said head engaging member and said steering linkage assembly in response to the tilting of said head engaging member resulting in a change in said vehicle direction, said actuating element further preventing a linking of said head engaging member and said steering linkage assembly in response to a lateral, horizontal rotation of said head engaging member.
Claim 3
Dependent Claim 60 words
The head actuated steering control apparatus according to claim 1 wherein said steering linkage assembly includes a steering lever, and wherein said actuating element includes an aperture for receiving said steering lever therethrough, said aperture having an inner surface, said steering lever selectively engaging the inner surface of said aperture in response to a tilting of said head engaging member.
Claim 4
Dependent Claim 90 words
The head actuated steering control apparatus according to claim 1 wherein said actuating element includes: a first rigid member for selectively linking said head engaging member and said steering linkage assembly in response to a lateral tilting of said head engaging member; a second rigid member for selectively linking said head engaging member and said steering linkage assembly in response to a forwardly or rearwardly directed tilting of said head engaging member; and a pivotable member for pivotally mounting said first and second rigid members to said head engaging member.
Claim 5
Dependent Claim 159 words
A human powered vehicle comprising: a seating arrangement for positioning an operator of said human powered vehicle in a substantially recumbent orientation; a steering system for regulating vehicle direction; a steering linkage assembly for controlling said steering system; and a head actuated steering control apparatus for controlling said steering linkage assembly, said head actuated steering control apparatus including a head engaging member for enclosing the head of skid operator, said head engaging member further including an actuating element for selectively linking said head engaging member and said steering linkage assembly in response to a tilting of said head engaging member, a linking of said head engaging member and said steering linkage assembly in response to the tilting of said head engaging member resulting in a change in said vehicle direction, said actuating element further preventing a linking of said head engaging member and said steering linkage assembly in response to a lateral, horizontal rotation of said head engaging member.
Claim 6
Dependent Claim 159 words
A human powered vehicle comprising: a seating arrangement for positioning an operator of said human powered vehicle in a substantially recumbent orientation; a steering system for regulating vehicle direction; a steering linkage assembly for controlling said steering system; and a head actuated steering control apparatus for controlling said steering linkage assembly, said head actuated steering control apparatus including a head engaging member for enclosing the head of skid operator, said head engaging member further including an actuating element for selectively linking said head engaging member and said steering linkage assembly in response to a tilting of said head engaging member, a linking of said head engaging member and said steering linkage assembly in response to the tilting of said head engaging member resulting in a change in said vehicle direction, said actuating element further preventing a linking of said head engaging member and said steering linkage assembly in response to a lateral, horizontal rotation of said head engaging member.
Claim 7
Dependent Claim 53 words
The human powered vehicle according to claim 4 further comprising: an operator actuated drive mechanism for propelling said human powered vehicle, said drive mechanism including a pair of hand levers and a pair of foot pedals, said hand levers and foot pedals disposed forwardly of said seating arrangement and said head engaging member.
Claim 8
Dependent Claim 58 words
The human powered vehicle according to claim 4 wherein said steering linkage assembly includes a steering lever, and wherein said actuating element includes an aperture for receiving said steering lever therethrough, said aperture having an inner surface, said steering lever selectively engaging the inner surface of said aperture in response to a tilting of said head engaging member.
Claim 9
Dependent Claim 89 words
The human powered vehicle according to claim 4 wherein said actuating element further includes: a first rigid member for selectively linking said head engaging member and said steering linkage assembly in response to a lateral tilting of said head engaging member; a second rigid member for selectively linking said head engaging member and said steering linkage assembly in response to a forwardly or rearwardly directed tilting of said head engaging member; and a pivotable member for pivotally mounting said first and second rigid members to said head engaging member.
