Abstract
A mechanical advantage device includes a base, a beam pivotably connected to the base at a fulcrum between a first end of the beam and a second end of the beam, a seat at the first end of the beam, and a load at the second end of the beam. In some embodiments, the mechanical advantage device includes structure, such as a linkage, for effecting oscillation of the beam by shifting weight along the beam. The mechanical advantage device may be a single-person seesaw. In some embodiments, the mechanical advantage device may be used to move a car or to generate power.
Claims19
A system for generating power, comprising:
- a base;
- a driving assembly including
- a beam pivotably connected to the base at a fulcrum between a first end of the beam and a second end of the beam;
- a load at the second end of the beam;
- a lock bar secured to the base;
- a lock arm having a first end pivotably connected to the beam by a lock arm support disposed near the second end of the beam and having a second end that is configured to engage the lock bar;
- a first link having a first end pivotably secured to the beam between the fulcrum and the first end of the beam and a second end that is free;
- and
- a cable having a first end connected to the first link near the first end of the link and having a second end connected to the second end of the lock arm,
- wherein rotation of the first link in a first direction pulls the cable to cause the second end of the lock arm to disengage the lock bar and to allow the load to rotate the beam such that a seat positioned at the end of the beam moves upwardly;
- a first driving link having a first end rotatably connected to the beam;
- and
- a second driving link having a first end rotatably connected to a second end of the first driving link and a second end;
- and a power generator operatively coupled to the second end of the second driving link.
