Abstract
The arm and leg-exercising machine is an apparatus that targets both the upper body and lower body to provide a full body workout. The upper and lower body workouts can be performed separately or simultaneously. The machine includes a generally U-shaped frame fixed to a base. Pedals and lateral handlebars are provided on the frame for respective leg (lower body) and arm (upper body) exercises. A three-drive mechanism including a plurality of pulleys or sprockets is coupled to the pedals and lateral handlebars and joined by bevel gears. A seat is mounted on the frame for strategically positioning an operator to employ the pedals and lateral handlebars.
Claims14
An exercising machine for optionally exercising upper and lower extremities, comprising:
- a U-shaped frame having a front end and a rear end spaced apart from the front end;
- a horizontal tubular member extending between the front end and the rear end;
- a split drive shaft encapsulated in the horizontal tubular member;
- a seat mounted on the U-shaped frame between the front end and the rear end;
- a front drive mechanism mounted on the frame and disposed adjacent the front end;
- a rear drive mechanism mounted on the frame and disposed adjacent the rear end;
- a middle drive mechanism mounted on the frame and disposed between the front end and the rear end;
- a foot pedal pulley member mounted on the frame, the foot pedal pulley member being connected to the middle drive mechanism and actuating the middle drive mechanism when the foot pedal pulley member is rotated;
- first and second handlebar members disposed on opposite sides of the seat, the first handlebar member being connected to the front drive mechanism and actuating the front drive mechanism when the first handlebar member is pivoted, the second handlebar member being connected to the rear drive mechanism and actuating the rear drive mechanism when the second handlebar member is pivoted;
- wherein a user optionally exercises upper body members by pivoting the handlebars, exercises lower body members by rotating the foot pedal pulley member, or exercises both upper and lower body members by simultaneously pivoting the handlebar members and rotating the foot pedal pulley member.

An arm and leg exercising machine, comprising:
- a U-shaped frame having spaced apart front and rear upright members and a cross member extending between the front and rear upright members;
- a front drive shaft rotatably journaled in the front upright member and extending toward the rear upright member, the front drive shaft having a front end and a rear end;
- a first bevel gear mounted on the rear end of the front drive shaft;
- a rear drive shaft rotatably journaled in the rear upright member and extending toward the front upright member, the rear shaft having a front end and a rear end;
- a second bevel gear mounted on the front end of the rear drive shaft;
- a front drive mechanism having:
- a front upper shaft extending from and rotatably mounted to the front upright member;
- a freewheeling clutch rigidly attached to the front upper shaft;
- an upper pulley mounted on the front upper shaft;
- a lower pulley rigidly mounted on the front end of the front drive shaft;
- and
- a belt extending around the upper and lower pulleys;
- a rear drive mechanism having:
- a rear upper shaft extending from and rotatably mounted to the rear upright member;
- a freewheeling shaft rigidly attached to the rear upper shaft;
- an upper pulley rotatably mounted on the rear upper shaft;
- a lower pulley rigidly mounted on the rear end of the rear drive shaft;
- and
- a belt extending around the upper and lower pulleys of said rear drive mechanism;
- a seat support extending upward from the cross member of the frame;
- a seat mounted on the seat support;
- a first lateral handlebar assembly having:
- a first lever arm rigidly fixed to the freewheeling clutch attached to the front upper shaft;
- a second lever arm rotatably attached to the rear upper shaft;
- and
- a first handlebar extending between the first and second lever arms laterally spaced from the seat, the first handlebar assembly actuating the front drive mechanism when rotated in one direction, but rotating freely on the upper shafts when rotated in an opposite direction;
- a second lateral handlebar assembly having:
- a third lever arm rigidly fixed to the freewheeling shaft attached to the rear upper shaft;
- a fourth lever arm rotatably attached to the front upper shaft;
- and
- a second handlebar extending between the third and fourth lever arms laterally spaced from the seat opposite the first handlebar, the second handlebar assembly actuating the rear drive mechanism when rotated in one direction, but rotating freely on the upper shafts when rotated in an opposite direction;
- a central drive mechanism having:
- a foot pedal-pulley assembly mounted to the frame;
- a double pulley mounted on the frame and spaced apart from the pedal-pulley assembly, the double pulley having a first pulley and a first pulley shaft extending therefrom, and a second pulley and a second pulley shaft extending therefrom orthogonal to the front and rear drive shafts;
- a flywheel mounted on the first pulley shaft;
- a third bevel gear mounted on the second pulley shaft, the third bevel gear meshing with the first bevel gear and also meshing with the second bevel gear;
- and
- a drive belt extending around the foot pedal-pulley assembly and the double pulley;
- whereby a user optionally exercises upper body members by pivoting the handlebars, exercises lower body members by rotating the foot pedal-pulley assembly, or exercises both upper and lower body members by simultaneously pivoting the handlebar members and rotating the foot pedal-pulley assembly.
