Flush Closet Seat Assist To Raise User Patents (Class 4/667)
  • Patent number: 9103106
    Abstract: The U-shaped closet flange is an auxiliary closet flange for use with a toilet that is seated onto an existing closet flange. The U-shaped closet flange fits around the rear base of a toilet from above the floor surface, and which improves the overall stability of the toilet by encircling the rear base of the toilet as well as across tops of opposing side lips of said base of said toilet. The U-shaped closet flange includes two generally parallel members that include grooves thereon to accommodate varying locales of bolts and bolt holes that extend up through the base of the toilet. The parallel members each include parallel base members that engage the floor surface, and interconnect with a cross member. Holes provided on the U-shaped closet flange enable screws to secure both the U-shaped closet flange and toilet in place to the surrounding floor.

  • Patent number: 8978173
    Abstract: A portable toilet has a bowl, a seat, and legs. The legs are telescopically extensible to allow positioning of the height of the bowl and wheels are mounted to the lower ends of the legs. The legs are spaced apart for fitting on opposite sides of a conventional building toilet and placing the bowl above the conventional toilet. The bowl has an open lower end which is enclosed by a slide door which is moved to open the lower end of the bowl and allow the contents of the bowl to spill therefrom into the conventional toilet. The contents of the bowl fall through the open lower end of the bowl and into the conventional building toilet. Preferably, pneumatic spring assist or an electric linear actuator are provided to aid in lifting and lowering the bowl after use. Water is provided for sweeping waste from within the bowl.

  • Patent number: 8556347
    Abstract: A sit/stand assistance includes a seat, a frame, a lifting device, and a driving device. This lifting device has a fixed portion connected to the frame and a movable portion pivoted with the seat so as to move the seat up or down. The driving device includes a link, a power portion, and a working rod. One of the power portion and the working rod is pivoted with the link. The other one is pivoted with the frame. When the power portion pushes the working rod, the working rod extends out so as to make said seat moving up or tilting. Hence, it can assist a user from a seated position to a standing position. So, it matches a user's continuous sit-to-stand motion. Plus, it can be directly applied on an existing flush toilet.

  • Patent number: 6161229
    Abstract: An apparatus is disclosed having a frame, front and rear guides rigidly secured to the frame and having front and rear channels passing therethrough, angling rearwardly from top to bottom. A toilet seat is operably connected to the frame and is movable between a lowered position and a raised position. A driver is operably connected to the toilet seat to move the seat between the lowered and raised positions. An armrest is provided, the armrest having front and rear members slidably passing through the front and rear channels of the front and rear guides, respectively. The front and rear armrest members are operably connected to the driver for moving them through the front and rear channels as the armrest moves between a lowered position and a raised position. The armrest may be operably connected to the driver so that a top portion of the armrest remains in a substantially horizontal position as the armrest moves between the lowered position and the raised position.

  • Patent number: 6154896
    Abstract: A powered lift assist toilet seat assembly is disclosed for assisting physically impaired persons in being raised from and lowered to a position above a conventional toilet to perform normal toilet functions. The seat assembly includes a movable platform having a central opening, a toilet seat secured over the opening, and a pair of handrails secured to the platform on both sides of the toilet seat. An arrangement of link members are pivotally connected between the movable platform and a lower frame for controlling a movement of the platform upon actuation of a drive member. The arrangement of link members is such that the movable platform is pivoted and moved forwardly when the platform is raised by actuation of the drive member. The arrangement of link members includes first and second link assemblies positioned on respective sides of the platform which are interconnected by a pair of transverse shafts to increase a load capacity and stabilize the platform during operation.

  • Patent number: 6098215
    Abstract: The present invention features a seat-lifting device for use with commonly available toilets, which is easily manufactured, easily installed in a household about the toilet. Such a seat-lifting device also would be simple and safe to use by the persons who desire to use the toilet. Such a seat-lifting device also would repeatedly, reliably and safely move the person from and between the upright and seated positions. Also featured are methods related thereto. A seat-lifting device according to the present invention features a toilet seat, a motor, a drive mechanism and seat lift linkage. The seat lift linkage is operably interconnected to the motor by the drive means and also is interconnected to the toilet seat. In this way, motion of the motor in a first direction causes the seat lift linkage to move the toilet seat from a one position, corresponding to a seated position, to a second position, an elevated position.

  • Patent number: 6067674
    Abstract: A toilet seat provides a lifting operation to assist a user to safely engage and disengage a toilet. A toilet seat is pivotally arranged to swing between two positions, an incline position and a horizontal position. While the seat is in the incline position, a user may approach it from a slightly bent standing position. By pushing against the seat, the user's weight loads an energy storing strut and forces the seat to lower gently into its horizontal position. After which, the user may benefit from energy stored in the strut. The seat applies a pressure which lifts the user from the toilet and into a natural standing position. In some versions, the seat is powered by a compressed gas strut which is loaded by a user's weight when the user engages the device. The loaded strut energizes the pivoting seat to provide a force which operates to remove the user from the toilet. Additionally, the seat may be arranged with armrests so the user's arm strength may be used to aid the transition to and from the toilet.
