Abstract
A propulsion and exercise device transmitting human energy from both the upper and lower body simultaneously. A frame (20) contains a rotatable upwardly extending mast (30) to which a foot engaging structure (38) is attached by linkage (48). A collapsible backrest (22) is situated on the frame and movable arms (62) with handles (56) are attached to the mast. Mechanical advantage and energy transmission is accomplished by pushing the foot engaging structure forward with ones legs while pulling the handles rearward propelling a vehicle or exercising the body.
Claims14
A human energy transmitting device comprising:
- (a) a main frame having parallel sides and a structural backrest;
- (b) a pivotal mast disposed between the parallel sides of said frame defining a compound lever freely rotatable thereupon for transmission of human power from combined body members;
- (c) rotatable foot engaging means operatively connected to said frame in a planar relationship positioned in such a manner as to be contiguous with ones feet when in the sitting position between the parallel sides of the frame while recumbently reclining on the backrest;
- (d) a thrust link freely reciprocable having one end pivotally mounted on the mast and the other end pivotally mounted on the foot engaging means for reciprocation of the mast when pressure is exerted upon the foot engaging means transmitting the force from ones feet when extendably pushing against the backrest to the mast;
- and,
- (e) energy transmitting means having handles thereupon yieldingly connected to said mast, receiving combined linear force from both the foot engagement and the handles when gripped thereupon transmitting ones total energy from both the upper and lower parts of the human body onto a resistance medium.
A human energy transmitting device attached to a watercraft comprising:
- (a) a main frame having parallel sides and a structural backrest that is collapsible.
- (b) a pivotal mast disposed between the parallel sides of said frame defining a compound lever freely rotatable thereupon for transmission of human power from combined body members;
- (c) rotatable foot engaging means having foot pads operatively connected to said frame in a planar relationship positioned in such a manner as to be contiguous with ones feet when in the sitting position between the parallel sides of the frame while recumbently reclining on the backrest;
- (d) an adjustable thrust link freely reciprocable having one end pivotally mounted on the mast and the other end pivotally mounted on the foot engaging means for reciprocation of the mast when pressure is exerted upon the foot engaging means transmitting the force from ones feet when extendably pushing against the backrest to the mast;
- (e) energy transmitting means having handles thereupon yieldingly connected to said mast receiving combined linear force from both the foot engagement and the handles when gripped thereupon transmitting ones total energy from both the upper and lower parts of the human body to the water for propulsion;
- and,
- (f) a pair of oars having blades on the ends attached to said energy transmitting means, propelling the craft by placing the oars into the water when the operators knees are bent and the mast is rearwardly positioned characterizing a propulsion stroke by pushing the foot engaging means forward with ones legs while simultaneously pulling the handles rearward causing the craft to be impelled forward in the water.
