Actuatable compact vehicle step
The invention relates to an actuatable compact vehicle step with first and second step portions that bifurcate from a single axis when moving from nested to extended positions to provide two or more tiered steps, the second step in a position substantially below the first step when deployed. In various embodiments, step portions travel on curved tracks from the nested position to allow them to be both well-concealed when nested and optimally extended when deployed.
1. An actuatable step for a vehicle comprising:
a first step portion,
a second step portion pivotally attached to the first step portion along a single axis, and
an actuator for moving first and second step portions between nested and deployed positions,
wherein the first and second step portions are configured to bifurcate from the single axis when the actuatable step is deployed,
the second step portion located substantially below the first step portion when the actuatable step is in a deployed position.
2. The actuatable step for a vehicle of claim 1 , further comprising a housing portion wherein the first and second step portions are configured to nest.
3. The actuatable step for a vehicle of claim 2 , wherein the first and second step portions are generally perpendicular to a horizontal plane of the ground when the actuatable step is in a nested position.
4. The actuatable step for a vehicle of claim 2 , further having:
a first step portion first end forming a first step,
a first step portion second end for attaching the first step portion to the housing, and two or more followers adjacent to the first step portion second end.
5. The actuatable step for a vehicle of claim 4 , further having two or more curved tracks upon which the two or more followers travel as the actuatable step moves between nested and deployed positions.
6. The actuatable step for a vehicle of claim 5 wherein the two or more curved tracks are substantially S-shaped.
7. The actuatable step for a vehicle of claim 6 , the actuatable step further concealable from the ordinary view of a user from outside of the vehicle when the actuatable step is in a nested position.
8. An actuatable compact vehicle step comprising:
a housing portion,
a first step portion connected to the housing portion,
a second step portion connected to the housing portion and pivotally attached to the first step portion only along a single axis,
an actuator for moving first and second step portions between nested and deployed positions,
the first and second step portions configured to bifurcate from the single axis to a deployed position,
the second step portion located substantially below the first step portion when the actuatable compact vehicle step is in a deployed position.
9. The actuatable compact vehicle step of claim 8 , further having a first step portion first end forming a first step, a first step portion second end for attaching the first step portion to the housing, and two or more followers adjacent to the first step portion second end.
10. The actuatable compact vehicle step of claim 9 , further having two or more curved tracks upon which the two or more followers travel as the actuatable compact vehicle step moves between nested and deployed positions.
11. The actuatable compact vehicle step of claim 10 wherein the two or more generally curved tracks are substantially S-shaped.
12. The actuatable compact vehicle step of claim 8 , wherein the first step portion has one or more acutely angled support members.
13. The actuatable compact vehicle step of claim 12 , wherein the single axis is located adjacent to a vertex of the one or more acutely angled support members.
14. The actuatable compact vehicle step of claim 8 , further configured to be concealable from the ordinary view of a user from outside of the vehicle when the actuatable compact vehicle step is in a nested position.
15. An actuatable step for a vehicle with:
two or more step portions;
an actuator for moving two or more step portions between nested and deployed positions,
one or more support members connected to each of the two or more step portions and actuator, the one or more support members each having two or more followers adjacent to an end; and
two or more S-shaped tracks upon which the two or more followers travel as the step moves between nested and deployed positions.
16. The actuatable step for a vehicle of claim 15 , wherein the one or more step portions are pivotally attached along and bifurcate from a single axis.
17. The actuatable step for a vehicle of claim 15 , the actuatable step further concealable from the ordinary view of a user from outside of the vehicle when the actuatable step is in a nested position.
18. An actuatable step for a vehicle comprising:
a first step portion,
a second step portion pivotally attached to the first step portion along a single axis, and
an actuator for moving first and second step portions between nested and deployed positions,
wherein the first and second step portions are configured to bifurcate from the single axis when the actuatable step is deployed, and
a housing portion wherein the first and second step portions are configured to nest.
19. An actuatable step for a vehicle comprising:
a first step portion,
a second step portion pivotally attached to the first step portion along a single axis, and
an actuator for moving first and second step portions between nested and deployed positions,
wherein the first and second step portions are configured to bifurcate from the single axis when the actuatable step is deployed, and
the actuatable step further concealable from the ordinary view of a user from outside of the vehicle when the actuatable step is in a nested position.
