Abstract
A lifting assembly, including a top plate, a bottom plate, a first pivoting plate assembly including a first plate pivotably connected to the top plate and a second plate pivotably connected to the first plate and the bottom plate, a second pivoting plate assembly including a third plate pivotably connected to the top plate and a fourth plate pivotably connected to third plate and the bottom plate, and a first bladder assembly engaged with the second plate and the bottom plate, the first bladder assembly operatively arranged to be inflated and deflated to displace the top plate with respect to the bottom plate.
Claims19
A lifting assembly, comprising:
- a top plate;
- a bottom plate;
- a first pivoting plate assembly including a first plate pivotably connected to the top plate and a second plate, the second plate including a first end pivotably connected to the first plate and a second end pivotably connected to the bottom plate;
- a second pivoting plate assembly including a third plate pivotably connected to the top plate and a fourth plate pivotably connected to the third plate and the bottom plate;
- and
- a first bladder assembly engaged with the second plate and the bottom plate, the first bladder assembly operatively arranged to be inflated and deflated to displace the top plate with respect to the bottom plate;
- wherein in an inflated state of the first bladder assembly, the first bladder assembly is arranged completely between the first end and the second end.
A lifting assembly, comprising:
- a top plate;
- a bottom plate;
- a first pivoting plate assembly, including:
- a first plate pivotably connected to the top plate proximate a first side of the top plate;
- and
- a second plate pivotably connected to the first plate and the bottom plate;
- a second pivoting plate assembly, including:
- a third plate pivotably connected to the top plate proximate a second side of the top plate, the second side being adjacent to the first side;
- and
- a fourth plate pivotably connected to the third plate and the bottom plate;
- and
- a first bladder assembly engaged with the second plate and the bottom plate, the first bladder assembly operatively arranged to be inflated and deflated to displace the top plate with respect to the bottom plate;
- wherein:
- the first pivoting plate assembly extends radially outward from a perimeter of the top plate in a collapsed state of the lifting assembly;
- and
- the second pivoting plate assembly extends radially inward from the perimeter of the top plate in the collapsed state.
