Handcycles

A hand powered cycling device comprising:

• a frame;
• a front wheel mounted on the frame;
• a rear wheel mounted on the frame;
• a hand crank mounted on said frame and a drive member connecting said hand crank and one of said wheels for imparting rotative driving of said wheel;
• a seat on said frame and the frame, wheels and seat in combination structured to provide seating of a person with the person's legs and feet extended forwardly at each side of the front wheel;
• a foot and leg support at each side of the front wheel including a forward most cross brace positioned for engagement by the bottom of the person's feet, said support structured for adjustment of the cross brace to position the cross brace as required for engagement by the bottom of the person's feet for persons having different body lengths;
• said foot and leg support at each side of the front wheel further comprised of a forwardly projected member;
• a rearwardly projected member laterally opposite the forwardly projected member;
• and a secondary cross member located rearward of the front most cross brace.

A hand powered cycling device comprising:

• a frame;
• a front wheel, a rear wheel, a hand crank and a seat including a back rest, all mounted to the frame whereby a person seated in the seat manipulates the hand crank for providing drive power to one of the wheels;
• said back rest including a first spine member extended upwardly from the frame, a pair of U-shaped brackets having upper, lower and center legs extended from opposite sides of the first spine member at a slight forwardly directed angle that positions the center leg substantially parallel to and spaced from the first spine member and slightly forward of the first spine member, each of said lower and upper legs having distal ends loosely coupled to the first spine member and readily decoupled by withdrawing each bracket laterally away from the first spine member;
• said seat bottom including a second spine member extended forwardly, a pair of U-shaped brackets having front, back and center legs extended from opposite sides of the second spine member at a slight upwardly directed angle that positions the center leg substantially parallel to and spaced from the second spine member and slightly above the second spine member, each of said front and back legs having distal ends loosely coupled to the second spine member and readily decoupled by withdrawing each bracket laterally away from the second spine member;
• a back rest cover and a seat bottom cover attached to each center leg of the brackets, respectively and drawn taut between said center legs, said covers as attached preventing withdrawal movement of the brackets and requiring removal of the cover for decoupling of the brackets.

A hand powered cycling device comprising:

• a frame;
• a front wheel, a pair of rear wheels, a hand crank and a seat all mounted to the frame and enabling a person seated in the seat to manipulate the hand crank providing drive power to the front wheel;
• said frame including a front frame portion and a rear frame portion, said front frame portion overlying in part the rear frame portion and the overlying parts of the front and rear frame portions connected together by two spaced apart front and rear pivotal connections, the rear pivotal connection positioned higher than the front pivotal connection and the two pivotal connections forming an axis around which the front frame portion pivots relative to the rear frame portion;
• said front frame portion defining a path of pivotal movement around said axis left and right of a centered position, a right and left resistively collapsible bumper mounted between the rear and front frame portions and projected into the path of movement of the frame portions, said bumpers while being collapsed increasingly resisting but permitting relative movement of the front frame portion and defining right and left limits of relative movement of said front frame portion.
