Devices and methods for body elevation
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.
1. A device for seat elevation, the device comprising:
a horizontal base portion fixedly connected to a substantially vertical support portion;
an elongated lift generator that extends and contracts along a longitudinal axis, the lift generator pivotally connected to the horizontal base portion;
a plurality of elongate members pivotally connected to the vertical support portion, the plurality of elongate members including a first elongate member pivotally connected to the lift generator on a first side of the horizontal base portion;
a drive shaft coupled to the first elongate member connecting the first elongate member to a second elongate member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the elongated lift generator from the first elongate member to the second elongate member; and
a seat portion attached to a plurality of vertical seat supports positioned substantially perpendicular to the planar seat portion, the plurality of vertical seat supports pivotally connected to the plurality of elongate members;
wherein as the lift generator extends, the plurality of elongate members guide the motion of the seat portion in a direction substantially parallel to the longitudinal axis of the lift generator from a first position, in which the seat portion is substantially horizontal and substantially centered over the base portion, to a second position, in which the seat portion is substantially perpendicular to the longitudinal axis of the lift generator and centered closer to the vertical support portion.
2. The device of claim 1 , further comprising a toilet including a toilet seat, the toilet positioned such that the toilet seat is located underneath the seat portion and within substantial proximity of the seat portion.
3. The device of claim 2 , wherein the seat portion includes a splash guard member extending downward from an inner opening in the seat portion.
4. The device of claim 3 , wherein the splash guard member extends below the toilet seat when the seat portion is in the first position.
5. The device of claim 1 , further comprising a protective cover.
6. The device of claim 5 , wherein the protective cover includes a plurality of one of handles and hand grips.
7. The device of claim 5 , wherein the protective cover includes an upper portion attached to the seat portion and a lower portion attached to one of the horizontal base portion and vertical support.
8. The device of claim 7 , wherein the upper and lower portions of the protective cover are in contact when the seat portion is in the first position.
9. The device of claim 1 , wherein the extension of the lift generator is activated by electronic buttons.
10. A device for seat elevation, the device comprising:
a base portion adapted to be placed around a front of a toilet, the base portion including a vertical support attached near the front of the toilet;
an elongated lift generator pivotally connected to the base portion;
a plurality of elongate members pivotally connected to the vertical support portion, the plurality of elongate members including a first elongate member pivotally connected to the lift generator on a first side of the horizontal base portion;
a drive shaft coupled to the first elongate member connecting the first elongate member to a second elongate member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the elongated lift generator from the first elongate member to the second elongate member; and
a seat portion pivotally connected to the plurality of elongate members;
wherein as the lift generator extends, the plurality of elongate members guide the motion of the seat portion in a direction substantially parallel to a longitudinal axis of the lift generator from a first position, in which the seat portion is substantially horizontal and substantially centered over the base portion, to a second position, in which the seat portion is substantially perpendicular to the longitudinal axis of the lift generator and centered closer to the vertical support portion.
11. The device of claim 10 , further comprising a protective cover, the protective cover including an upper portion attached to the seat portion and a lower portion attached to the base portion.
12. The device of claim 11 , wherein the upper and lower portions of the protective cover are in contact when the seat portion is in the first position.
13. The device of claim 11 , wherein the upper portion includes a splash guard member extending downward from an inner opening in the seat portion.
14. The device of claim 13 , wherein the splash guard member extends below a toilet seat when the seat portion is in the first position.
15. The device of claim 14 , further comprising a toilet including a toilet seat, wherein the splash guard member extends below the toilet seat when the seat portion is in the first position.
16. The device in claim 11 , wherein the upper portion includes a plurality of one of handles and hand grips.
17. A method for elevation of a seat connected to an assembly, the assembly including a horizontal base portion fixedly connected to a substantially vertical support portion, an elongated lift generator pivotally connected to the horizontal base portion, a plurality of elongate members pivotally connected to the vertical support portion, the plurality of elongate members including a first elongate member pivotally connected to the lift generator on a first side of the horizontal base portion, a drive shaft coupled to the first elongate member connecting the first elongate member to a second elongate member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the elongated lift generator from the first elongate member to the second elongate member, and a seat portion attached to a plurality of vertical seat supports positioned substantially perpendicular to the planar seat portion, the plurality of vertical seat supports pivotally connected to the plurality of elongate members, the method comprising:
extending the lift generator along a longitudinal axis;
wherein as the lift generator extends, the plurality of elongate members guide the motion of the seat portion in a direction substantially parallel to the longitudinal axis of the lift generator from a first position, in which the seat portion is substantially horizontal and substantially centered over the base portion, to a second position, in which the seat portion is substantially perpendicular to the longitudinal axis of the lift generator and centered closer to the vertical support portion.
18. The method of claim 17 , further comprising contracting the lift generator along the longitudinal axis.
19. The method of claim 18 , wherein the contracting includes matching an upper portion of a protective housing with a lower portion of the protective housing.
20. The method of claim 17 , wherein the extending is activated upon input from a button coupled to the seat portion.
