An impact absorption apparatus includes a force transfer member including a base and a sidewall extending from the base, the base including an opening, a shock absorber disposed within the force transfer member and resting on the base, the shock absorber including a through hole, a plate disposed within the force transfer member and resting on the shock absorber, the plate including a through hole, and a fastener that extends through the base opening, the shock absorber through hole, and the plate through hole, the fastener including an end protruding from the base opening, the fastener end configured to secure the force transfer member to a support surface. The force transfer member is configured so that when an impact force is applied to the force transfer member, the force is transferred from force transfer member to the shock absorber.
1. An impact absorption apparatus comprising:
a force transfer member including:
a base having an opening; and
a bumper including a sidewall extending from the base, the sidewall of the bumper including an impact deflection portion and one or more flanges extending from the impact deflection portion, each of the one or more flanges including a notch causing at least a portion of the flange to be elevated above a support surface,
a shock absorber disposed within the force transfer member and resting on the base, the shock absorber including a through hole,
a plate disposed within the force transfer member and resting on the shock absorber, the plate including a through hole, and
a fastener that extends through the base opening, the shock absorber through hole, and the plate through hole, the fastener including an end protruding from the base opening, the fastener end configured to secure the force transfer member to the support surface, and
the force transfer member being configured so that when an impact force is applied to the force transfer member, the force is transferred from force transfer member to the shock absorber.
2. The impact absorption apparatus of claim 1 wherein a diameter of the opening of the base is greater than a diameter of the fastener.
3. The impact absorption apparatus of claim 1 wherein the impact deflection portion has a substantially semi-circular shape.
4. The impact absorption apparatus of claim 3 wherein the base has a substantially semi-circular shape.
5. The impact absorption apparatus of claim 3 wherein the shock absorber has a substantially semi-circular shape.
6. The impact absorption apparatus of claim 3 wherein the plate has a substantially semi-circular shape.
7. The impact absorption apparatus of claim 1 wherein the notch has a rectangular shape.
8. The impact absorption apparatus of claim 1 wherein the notch has a triangular shape.
9. The impact absorption apparatus of claim 1 wherein each of the one or more flanges has a substantially triangular shape.
10. The impact absorption apparatus of claim 1 wherein the impact absorption apparatus is configured to evenly distribute a force of impact from the force transfer member into the shock absorber.
11. The impact absorption apparatus of claim 1 wherein the shock absorber comprises an elastomeric material.
12. The impact absorption apparatus of claim 11 wherein the elastomeric material is a rubber material.
13. The impact absorption apparatus of claim 1 wherein the fastener comprises a bolt.
14. The impact absorption apparatus of claim 1 wherein the sidewall has an elongate tubular shape with a first cross-sectional diameter.
15. The impact absorption apparatus of claim 14 further comprising:
a cover having an elongate tubular shape with a second cross-sectional diameter greater than the first cross-sectional diameter,
wherein the sidewall is disposed within the cover and the cover is able to rotate relative to the sidewall.
