Abstract
A movable toilet seat, the seat portion of which remains horizontal while raising and lowering. An upper frame capable of having a common toilet seat attached raises and lowers with respect to a lower frame. The lower frame provides support for the upper frame and is attached to the toilet. When the upper frame is raised, it also travels forward to allow more clearance from the toilet for the user. When the upper frame is lowered, it travels back to situate the user directly over the toilet bowl. Preferably, a reversible motor is used to raise and lower the upper frame. However, alternative embodiments encompass the use of an air shock absorber and a manual jack.
Claims9
A movable toilet seat, comprising:
- a lower frame;
- an upper frame to which a toilet seat may be attached and upon which a person may stably be seated,
- said upper frame moving relatively forward of said lower frame when said upper frame is raised;
- means for connecting said upper frame to said lower frame, said connecting means pivotally attached to said upper and lower frames so that said upper frame is kept horizontal when said upper frame moves relative to said lower frame;
- and
- means for moving said upper frame relative to said lower frame, said moving means connected to said upper frame.
A movable toilet seat comprising:
- a lower frame;
- an upper frame to which a toilet seat may be attached and upon which a person may stably be seated, said upper frame moving relatively forward of said lower frame when said upper frame is raised;
- a plurality of struts of equal length connecting said upper frame to said lower frame, said plurality of struts each pivotally connected to said upper and lower frames so as to define a parallelogram so that said upper frame is kept horizontal when said upper frame moves relative to said lower frame and said plurality of struts not passing through an angle defined with respect to said lower frame of greater than ninety degrees;
- and
- means for moving said upper frame relative to said lower frame, said moving means pivotally coupled to said upper frame.
