Stepwell cover apparatus
View Patent ↗A stepwell cover apparatus for use in a vehicle having a stepwell including a step that is located below the floor of the vehicle. The apparatus includes a horizontal cover that may be retracted to a position below the floor in order to expose the steps of the stepwell and may be extended to a position flush with the floor in order to conceal the steps of the stepwell. In addition, the stepwell cover apparatus includes a drive mechanism for driving the horizontal cover between the fully extended and the fully retracted positions, a guide mechanism for guiding the horizontal cover during movement and pivot members that cooperate with the drive and guide mechanisms to raise the horizontal cover to a level flush with the floor when the cover reaches the fully extended position.
1. A stepwell cover apparatus for use in a vehicle having a floor and a stepwell including at least one step including:
a horizontal cover;
a pivoting member having a first end and a second end, the first end being joined to the horizontal cover;
a drive mechanism including a rod and a drive assembly able to traverse the length of the rod and including an arm attached to the second end of the pivoting member;
a guide mechanism including a sliding assembly, the pivoting member pivotally connected to the sliding assembly between the first end of the pivoting member and the second end of the pivoting member;
a first stop member attached to the horizontal cover and including an opening;
a first dowel located within the opening of the first stop member including a first stationary end and a second end;
wherein movement of the drive assembly moves the horizontal cover between a fully retracted position and a fully extended position, the horizontal cover exposing the at least one step and being located below the floor when in the fully retracted position and concealing the at least one step and being located flush with the floor when in the fully extended position.
2. The stepwell cover apparatus as set forth in claim 1 further including a frame having a base and a plurality of walls defining an inner space housing the guide mechanism when in the fully retracted position.
3. The stepwell cover apparatus as set forth in claim 1 further including a plate connected to the first stationary end of the dowel.
4. The stepwell cover apparatus as set forth in claim 3 wherein the plate includes an opening and the first stationary end of the dowel is located within the opening.
5. The stepwell cover apparatus as set forth in claim 1 wherein the drive mechanism further includes a motor and a pulley mechanism, the motor being connected to the rod by way of the pulley mechanism.
6. The stepwell cover apparatus as set forth in claim 1 wherein the drive assembly further includes a nut threaded onto the rod, a nut cage joined to the nut and wherein the arm of the drive assembly extends from the nut cage.
7. The stepwell cover apparatus as set forth in claim 1 further including a bracket attached to the horizontal cover, the bracket connecting the first end of the pivot member to the horizontal cover.
8. The stepwell cover apparatus as set forth in claim 7 further including a second pivot member, the second pivot member having first end joined to the bracket and a second end joined to the sliding assembly.
9. The stepwell cover apparatus as set forth in claim 8 wherein rotation of the pivot members cause a vertical movement of the horizontal cover.
10. The stepwell cover apparatus as set forth in claim 1 further including a vertical cover joined to the horizontal cover.
