Abstract
The present invention relates to an energy absorbing apparatus. Specifically, the apparatus comprises a first disk and a second disk atop the first disk, and a plurality of collapsible arms around the perimeter of the disks connecting the first disk and the second disk, and an elastic material disposed between at least two of the collapsible arms, wherein collapsing of the arms causes the elastic material to stretch, storing kinetic energy from the vertical direction as potential energy in the horizontal direction, wherein release of the potential energy from the elastic material causes the arms to return to an uncollapsed state. Systems utilizing the energy absorbing apparatus, methods of making and methods of using the same are further provided.
Claims12
An energy absorbing apparatus comprising:
- a first planar element and a second planar element, the first planar element disposed adjacent to and in face-to-face relation with the second planar element;
- a plurality of bendable arms, each of the bendable arms disposed between the first planar element and the second planar element, a first end of each of the bendable arms hingedly connected to the first planar element, and a second end of each of the bendable arms hingedly connected to the second planar element, each of the bendable arms further comprising a hinge at a midpoint between the first and second ends thereof and an aperture through each of the bendable arms at the midpoint thereof such that movement of the first planar element toward the second planar element causes the arms to bend outwardly;
- and
- an energy storage element connected between the plurality of arms and sandwiched between the first and second planar elements, the energy storage element storing kinetic energy as potential energy when the first planar element moves toward the second planar element, the stored potential energy transforming into kinetic energy to move the first planar element away from the second planar element,
- wherein the energy storage element comprises an elastic band comprising a central portion and a plurality of legs extending from the central portion outwardly, each of the plurality of legs having a terminal end, each terminal end having an upwardly extending tab and a downwardly extending tab, the terminal end of each of the plurality of legs extending through the aperture of each of the respective bendable arms, wherein the upwardly extending tab and the downwardly extending tab of each of the plurality of legs of the elastic band are held on an outside surface of each of the bendable arms via a hook.
A system for absorbing energy comprising:
- an article;
- and
- at least one energy absorbing apparatus disposed on or within the article comprising a first planar element and a second planar element, the first planar element disposed adjacent to and in face-to-face relation with the second planar element, a plurality of bendable arms, each of the bendable arms disposed between the first planar element and the second planar element, a first end of each of the bendable arms hingedly connected to the first planar element, and a second end of each of the bendable arms hingedly connected to the second planar element, each of the bendable arms further comprising a hinge at a midpoint between the first and second ends thereof and an aperture through each of the bendable arms at the midpoint thereof such that movement of the first planar element toward the second planar element causes the arms to bend outwardly, and an energy storage element connected between the plurality of arms and sandwiched between the first and second planar elements, the energy storage element storing kinetic energy as potential energy when the first planar element moves toward the second planar element, the stored potential energy transforming into kinetic energy to move the first planar element away from the second planar element, wherein the energy storage element comprises an elastic band comprising a central portion and a plurality of legs extending from the central portion outwardly, each of the plurality of legs having a terminal end, each terminal end having an upwardly extending tab and a downwardly extending tab, the terminal end of each of the plurality of legs extending through the aperture of each of the respective bendable arms, wherein the upwardly extending tab and the downwardly extending tab of each of the plurality of legs of the elastic band are held on an outside surface of each of the bendable arms by a hook.
