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;
a lift generator that extends and contracts along a longitudinal axis, the lift generator pivotally connected to the horizontal base portion;
a plurality of members pivotally connected to the vertical support portion, the plurality of members including a first member pivotally connected to the lift generator on a first side of the horizontal base portion;
a drive shaft coupled to the first member connecting the first member to a second member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the lift generator from the first member to the second 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 members;
wherein as the lift generator extends, the plurality of 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;
a lift generator pivotally connected to the base portion;
a plurality of members pivotally connected to the vertical support portion, the plurality of members including a first member pivotally connected to the lift generator on a first side of the horizontal base portion;
a drive shaft coupled to the first member connecting the first member to a second member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the lift generator from the first member to the second member; and
a seat portion pivotally connected to the plurality of members;
wherein as the lift generator extends, the plurality of 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, a lift generator pivotally connected to the horizontal base portion, a plurality of members pivotally connected to the vertical support portion, the plurality of members including a first member pivotally connected to the lift generator on a first side of the horizontal base portion, a drive shaft coupled to the first member connecting the first member to a second member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the lift generator from the first member to the second 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 members, the method comprising:
extending the lift generator along a longitudinal axis;
wherein as the lift generator extends, the plurality of 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.
