Abstract

Devices and methods are presented for elevating seat devices. The device allows a vertical and forward motion of a seat from a first position to a second position. Such motion more resembles a natural body motion during the standing motion. A similar but converse motion is also possible with movement from a standing position to a sitting position.

Claims (15)

1. A device for seat elevation, the device comprising:

a seat base having a substantially planar seat portion and vertical seat supports positioned substantially perpendicular to the planar seat portion;

an elongated lift generator having a longitudinal axis, a top portion, a bottom portion, and in connection with the vertical seat supports, wherein the lift generator is substantially positioned at an angle from a floor at all times during use with its bottom portion closest to the floor; and

a horizontal base portion fixedly connected to a substantially vertical support portion; wherein the vertical support portion has a first and a second substantially rigid and linear elongate members pivotally connected, the first member near a top point of the vertical support portion and the second member near a middle point of the vertical support portion, the first member extending horizontally, connecting to the lift generator and connecting pivotally to a point of the vertical seat support, and the second member extending at a downward angle from its connection with the vertical support portion and connecting pivotally to a lower point of the vertical seat support than the first member;

wherein the lift generator moves the first member which then moves the seat portion in a direction parallel to the longitudinal axis of the lift generator, from a first position in which the seat portion is substantially horizontal to a second position that is different in vertical, horizontal and rotational tilt placement from the first position such that the seat portion is closer to the vertical support portion and is substantially perpendicular to the longitudinal axis of the lift generator.

2. The device of claim 1 , wherein the first position is substantially horizontal and the second position is higher and more forward than the first position.

3. The device of claim 1 , wherein the seat portion is connected to a toilet seat.

4. The device of claim 3 , further comprising a protective cover.

5. The device of claim 4 , further comprising handles or hand grips attached to the protective cover.

6. The device of claim 4 , further comprising a splash guard member extending downward from a center opening on the protective cover to be placed inside a toilet bowl.

7. The device of claim 1 , wherein the elevation motion is activated by electronic buttons.

8. The device of claim 1 , wherein the lift generator includes an elongated member that connects with the first member.

9. The device of claim 1 , wherein the lift generator pushes the seat portion in the direction of the longitudinal axis when the seat portion travels from the first position to the second position.

10. The device of claim 1 , wherein in the first position, the seat portion is such that a user may sit on the seat portion and whose legs would be closer to the vertical supports than the lift generator.

11. The device of claim 1 , wherein in the second position, the seat portion is angled such that a user may rest his back side against the seat portion and whose legs would be closer to the vertical supports than the lift generator.
