The toilet seat, the lid and the backrest are connected relative to one another such that they are positionable in alternative chair and toilet-use modes. The lid is behind the generally upright backrest when the assembly is in the toilet-use mode and is on the toilet seat when the assembly is in the chair mode. The assembly can have self-supporting legs whereby it can form a standalone chair remote from the toilet. When in a male urination mode, the toilet seat is lifted and the backrest is in a lifted, generally horizontal position.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of co-pending provisional application Ser. No. 61/726,479, filed Nov. 14, 2012, and whose entire contents are hereby incorporated by reference.


BACKGROUND
With the lid of a toilet in a down position over/on the toilet seat, a person can sit on the lid supported by the toilet bowl. However, this seating arrangement is not attractive, comfortable or flexible in its use.
SUMMARY
According to an aspect of the disclosure provided herein is an assembly that can be easily converted by a user between a non-bathroom (remote) chair mode (suitable for use in a living room or office, for example) and a bathroom seating mode where it can be easily converted to a toilet-use mode over a toilet bowl or the like.
According to one aspect of the disclosure provided herein is an assembly that includes a toilet seat, a chair seat lid and a backrest. The toilet seat, the lid and the backrest are connected relative to one another such that they are positionable in alternative standard seat, toilet seat, and toilet seat-up positions. The backrest is in front of the lid when the assembly is in the toilet seat position (toilet-use mode), and the lid is on the toilet seat when the assembly is in the standard seat position.
According to another aspect of the disclosure provided herein is a chair assembly having an alternative toilet-use mode wherein the backrest can be flipped up and then back down to conceal a raised toilet lid and also position the underside (bowl-facing side) of the toilet lid out of contact with the user.
According to a further aspect of the disclosure provided herein is a toilet chair positionable over a toilet wherein the chair has a toilet seat and a pull-out footrest for a user sitting on the toilet seat. When the footrest is in a stored position it is generally flush with the surrounding skirt of the chair and thus practically invisible.
According to a still further aspect of the disclosure provided herein is a chair assembly positionable in a toilet-use mode with the top surface of its toilet seat exposed and the toilet seat positioned over a toilet bowl and a chair mode distant from the toilet and with its toilet seat separated from the chair. The separated toilet seat can be attached to an operative position on the toilet.
According to another aspect of the disclosure provided herein is a chair assembly that is fully supported by legs thereof such that the chair assembly can be positioned in a usable toilet seat position over a toilet and then moved away from the toilet to form a standalone chair with a seat, which is not the toilet seat, forming the sitting support surface. As an example, the chair can have casters at the end of its legs so that the chair can be easily rolled between a position over a toilet and a position remote from the toilet. The casters can be locked when the chair assembly is in a desired position to prevent it from rolling.
According to yet another aspect of the disclosure provided herein is a chair assembly that forms a chair having a chair seat, a toilet seat, a backrest and arms on opposite sides of the chair seat wherein the arms are adjustable in the x, y and z directions to allow a user to personally customize the positions of the arms for chair mode and for toilet-use mode.
According to still yet another aspect of the disclosure provided herein is a method of reconfiguring a chair assembly herein between a chair mode and a toilet seat mode including raising a backrest to a flipped up position, pivoting a chair seat lid off of a toilet seat lid over a toilet to a raised position behind the flipped-up backrest and lowering the backrest to a flipped-down position so that the chair seat lid is positioned behind the backrest and the backrest is positioned behind a user's back when sitting on the exposed toilet seat.
According to a still further aspect of the disclosure provided herein is a frame (or chair) assembly including a frame, a backrest pivotally attached to an upper location of the frame, a chair seat lid pivotally attached to a lower location, a toilet seat pivotally attached to a lower location and the chair seat lid being pivotal between alternative positions on the toilet seat and behind the backrest. The toilet seat can be detached from the lower location on the frame and pivotally attached to a toilet bowl. For example, the lid and the toilet seat can be pivotally attached to a bottom bar of the frame and the backrest can be pivotally attached with a hinge to a top bar of the frame. An alternative is for the top and bottom bars to be attached to the unit via their own separate supports instead of being attached to one another via the vertical bars of a shared frame.
According another aspect of the present disclosure provided herein is a chair assembly having a backrest, a chair seat lid, a toilet seat and a skirt. The chair assembly is positionable relative to a toilet such that the toilet seat is positionable over the toilet bowl and the skirt surrounds a forward portion of the toilet bowl. The chair assembly includes a footrest positionable in a non-use hidden position and an alternative extended use position. When in the non-use hidden position a bottom face of the footrest forms a portion of the skirt.
According to a further aspect of the present disclosure provided herein is a chair assembly having a seat and a footrest, which is positionable in a non-use position and an alternative extended use position. Movement of the footrest from the hidden position to the use position includes moving the footrest through mechanical means outwardly away from the seat, then pivot (rotate) ninety degrees forwardly and then lift upwardly.
According to a still further aspect of the present disclosure provided herein is a chair assembly having a backrest, a chair seat lid, a toilet seat and a headrest. The chair assembly is positionable relative to a toilet such that the toilet seat is disposed over the toilet bowl. The backrest is curved as is its supporting frame such that the top of the frame is above the tank of the toilet, which allows for the backrest to have additional curvature without impeding on the availability of the surface area of the chair seat lid or the toilet seat. If the backrest has a large convex curvature (lumbar support, for example), it may extend forward far enough that, without such a curvature in the frame, it would obstruct a seated user's access to the full seating surface area of the lid or the toilet seat. The curved frame support allows for the backrest to attach further back so the foremost point of the backrest (the user-facing curvature) does not extend forward so as to be on top of or over the lid or seat area.
According to another definition of the present disclosure provided herein is a chair assembly having a chair mode and an alternative toilet seat mode. The chair assembly when positioned over a toilet and in the chair mode makes the bathroom space conducive to non-toilet-specific activities, such as resting, computer work and reading.
According to a further definition of the present disclosure provided herein is a chair assembly having a toilet seat, a chair seat lid, a backrest and one or more telescoping legs with bottom lockable casters. The chair assembly can be wheeled into position over a toilet bowl and lowered into place via its telescoping legs.
According to yet another definition of the present disclosure provided herein is a chair assembly that includes: a rectangular, frame-like support; a backrest attached to a top bar of the support by a top friction hinge; a chair seat lid attached to a bottom bar of the support by a bottom friction hinge; a toilet seat attached to the bottom bar at either side of the bottom friction hinge by a hinge apparatus with a small opening that allows the toilet seat to be hooked or clipped onto the bottom bar, and also detached from the bar and attached via a similar fixture to the toilet hardware.
According to yet a still further definition of the present disclosure provided herein is a chair assembly having a toilet seat and a chair seat lid and operatively positionable over a bowl of a toilet without a toilet seat. The chair assembly is movable from the operative position to a location remote from toilet. The toilet seat is removable from the chair assembly and operatively attachable to the toilet itself. The chair assembly when in the remote location, the toilet seat removed and the lid in a down position forms an adjustable, attractive and comfortable chair, which in addition to the backrest can have arms and so forth.
Further objects and advantages of the disclosure will become apparent from a consideration of the drawings and ensuing description.

DETAILED DESCRIPTION
A chair assembly of the present disclosure is illustrated generally at 100 in FIG. 1 and shown in position over a toilet as depicted generally at 110 and including a bowl 114 and a tank 118. The chair assembly 100 is illustrated in a bathroom chair mode.
The chair assembly can include a toilet seat 130, a chair seat lid 140, a backrest 150 and a frame 160. The toilet seat 130 and the lid 140 are connected with a hinge 170 at a lower bar 180 of the frame 160, and the backrest 150 is connected with a hinge 190 to an upper bar 200 of the frame. The toilet seat 130 can be made or plastic or porcelain, or cushioned and upholstered in a non-soilable material such as vinyl or leatherette. The lid 140 can have approximate length and width dimensions of nineteen and seventeen inches, respectively. And the backrest 150 can have approximate height and width dimensions of twenty-three inches. The backrest 150 and the lid 140 can be made with a contoured, cushioned surface upholstered in a non-soilable vinyl, rubber or leatherette material. The lid 140 can be a cushioned lid.
A headrest 210 can be attached to an extension 220 of the frame (or the frame) itself and can be pivotable about a hinge 230, as shown for example in FIG. 2.
The frame 160, in turn, can be mounted via screws and/or rivets to a platform support 240 of the chair assembly. The platform support 240 has a large central opening, as can be seen for example in FIG. 17, over the toilet bowl and under the opening of the toilet seat 130 which is in a toilet-use mode. The frame 160 can be made of metal or plastic as can the platform support. The platform 240 can be supported on the floor and over the toilet 110 by height-adjustable (telescoping) legs 260.
A skirt 270 can depend down from the platform support 240, at least partially encircling the toilet 110 to at least partially hide the toilet. The skirt 270 can be made, for example, of plastic, laminate or sealed wood.
Side portions 280 of the skirt can form outward surfaces of side compartments. The side compartment can be a box or sliding drawer 290 such as shown in FIGS. 2 and 21A. Alternatively, the side compartment can be a tilt-down compartment 300 such as shown in FIGS. 6 and 7. The side compartments can be used to hold reading material, toilet tissue or reading glasses, for example, or even a fold-out tray 310 as depicted in FIGS. 21A-21C. When closed, the side portions 280 are flush with the surrounding skirt 270 and thereby are practically hidden. The side compartments can include notches or handles to assist in opening and closing.
A front portion 320 of the skirt can form an outer surface of a footrest 330, as can be understood from FIG. 1, To position the footrest 330 in an operative position, it is pulled out (as shown in FIG. 5), rotated ninety degrees (as shown by the arrow 340 in FIG. 5 and the position of FIG. 6) and then lifted up (as shown by the arrow 350 of FIG. 6 and the position of FIG. 7). The movement can be manually along tracks and by pivots, or it can be done mechanically such as by actuation by a lever or by an electrical motor. The footrest can be positioned even higher than depicted in FIG. 7, such as by the embodiment of FIG. 21A where the footrest when in an operative position can be about twenty-four inches above the floor. Positioning the footrest a distance above the floor and when the chair assembly is in a toilet-use mode assists a user sitting on the toilet seat 130 by raising the user's feet so as to allow for posture more conducive to defecation.
Also attached to and supported by the platform 240 can be left and right chair arms 360 having armrests 370 and elongate connector arms 380. The arms, or more particularly the armrests 370, are repositionable by the user as can be understood from FIGS. 9A, 9B and 9C. Referring thereto it can be seen that the connector arms 380 can be mounted with a ball joint socket 390 in the platform, thereby allowing different angles of rotation, as shown by the arrow 394 in FIG. 9C. The connector arm 380 can also having a telescope construction, allowing it to be shortened and lengthened as can be understood by the arrow 400 in FIG. 9B. The repositioning of the arm 360 allows the user to adjust the armrest 370 as may be needed for his physique and/or for his desires and/or to position the armrest out of the way such as for accessing the fold-up tray 310 or the side compartment 290, 300.
The armrest 370 can have a flip-out construction, allowing a top panel 410 to be rotated outwardly as shown by arrow 420 in FIG. 8. And the arrow 430 in FIG. 8 shows a tray foldout construction 440 to extend over the lap of a user sitting on the lid 140.
The alternative or supplemental tray 310 can be provided as shown in FIGS. 21A-C. Referring thereto, the compartment is pulled out, the tray 310 is (manually) lifted up as shown by arrow 460 in FIG. 21A to the lifted-up position of FIG. 21B. The tray portion 470 is then pulled over as shown by arrow 480 in FIG. 21B to the operative position of FIG. 21C where it is at the side of a user sitting on the lid. The user can then return the tray to its stored position using a reverse movement sequence.
Still referring to FIGS. 21A-C, the skirt 500 is a half-length skirt, which in contrast to the full-length skirt 270 of FIG. 1, for example, provides easier access to the height-adjustable legs 260, and provides for a more pleasing aesthetic appearance when on toilets of generally any height.
The chair assembly 540 can be provided with no skirt as shown in FIGS. 3 and 4. The embodiment of these figures also includes a different footrest construction 520, which includes a first friction hinge 530, attached to a track 540 along the edge of the platform 240, and via a support bar 550 to a second friction hinge 560 on the footrest surface. The first hinge 530 slides in a groove along and around the edge of the platform as shown by the arrow 570 in FIG. 3 and between the front position in FIG. 3 and the out-of-the-way position in FIG. 4. When in the forward position it can be lifted upwards about the pivot axis of the friction hinge attached to the footrest surface to a desired operative raised position and releasably held in place by friction or by notches.
The different relative positions of the lid 140, the backrest 150 and the toilet seat 130 to define different uses or modes of the chair assembly will now be described. With the toilet seat 130 down, the lid 140 down on the seat and the backrest 150 in an upright position, the assembly is in a chair mode. This is shown, for example in FIGS. 1, 3, 11 and 21A. When the assembly is positioned over a toilet 110, the chair mode can be referred to as a toilet chair mode; and when the assembly is remote from the toilet, the chair mode can be referred to as a toilet-remote chair mode.
To position the chair assembly in a toilet-use mode, the backrest 150 is pivoted up about its hinge as shown by the arrow 600 in FIG. 11 to the raised position in FIG. 12. The lid 140 is then pivoted up, as shown by the arrow 610 in FIG. 12 about its hinge to the raised upright position of FIG. 13A. And the backrest 150 is then lowered as shown by the arrow 620 in FIG. 13A to the lowered position as illustrated in FIG. 14, whereby the toilet seat 130 is in an exposed toilet-use seating position above the toilet bowl.
The chair assembly is in a standing male urination position as shown in FIG. 13B with the backrest 150 still in the raised position but with the toilet seat 130 in a raised generally upright position with respect to the bowl 114. Continuing to refer to FIG. 13B, the lid 140 is between the toilet tank 118 and the upright toilet seat 130. In contrast, in the toilet-use mode of FIG. 14, the lid 140 is between the tank 114 and the lowered, generally upright backrest 150.
The legs 260 can be height-adjustable as mentioned above. This allows for easy and accurate placement of the chair assembly over toilet bowls of generally any height. With the chair assembly in a raised position as illustrated in FIG. 10, the lengths of the legs 260 are shortened as depicted by the arrow 630 in FIG. 10 until the chair assembly is at the proper height as shown in FIG. 11.
To assist in the positioning and repositioning of the chair assembly relative to a toilet and to desired remote chair locations, the legs 260 can have lockable casters 640, as shown in FIGS. 15 and 16, for example. This allows the chair assembly to be easily rolled into place over a toilet bowl as shown in FIG. 15, and then later rolled to a remote location as shown by the arrow 650 in FIG. 16.
The toilet 110 of FIGS. 1 and 15, for example, does not have a toilet seat to provide for a better fit of the chair assembly over the toilet bowl. Thus, when the chair assembly is moved away from the toilet, as shown in FIG. 16, the toilet left behind does not have a toilet seat. Advantageously, the toilet seat 130 can be removed from the chair assembly as shown by the arrow 654 in FIG. 17. And the removed toilet seat can be clipped 660 onto the hardware 670 of the toilet, as can be understood from FIGS. 18-20.
FIG. 22 shows that the frame 680 can have a curved configuration. This figure also shows that the backrest 690 is also curved. Thus, the top 700 of the frame is above the tank 118 of the toilet. This arrangement allows for the backrest 690 to have additional curvature without impeding on the availability of the surface area of the chair seat lid 140 or the toilet seat 130. If the backrest 690 has a large convex curvature (lumbar support, for example), it may extend forward far enough that, without such a curvature in the frame, it would obstruct a seated user's access to the full seating surface area of the lid or the toilet seat. Thus the curved frame 680 allows for the backrest 690 to attach further back so the foremost point of the backrest (the user-facing curvature) does not extend forward so as to be on top of or over the lid or seat area.
Instead of making for an entire chair assembly with a support platform, the disclosure can take the form of a chair or seat assembly as shown in FIGS. 23-26. This simpler and cheaper construction still provides for a chair mode as depicted in FIG. 24 with the toilet seat 700 on the bowl, the chair seat lid 710 on the toilet seat (to define a chair seating surface) and the backrest 720 (which a typical toilet does not have) generally upright and between the toilet tank and the bowl.
The toilet seat and the lid are connected by a hinge 730 to a support frame 740 of the assembly. And the backrest is attached to an opposite upper bar of the support frame by another hinge. The assembly can be attached to existing hardware 750 of the toilet with the toilet's seat removed, as depicted in FIG. 23.
Then to reconfigure the assembly into the toilet-use mode the backrest 720 is lifted and the lid 710 is lifted up behind the frame 740, as shown in FIG. 25. Then with the backrest 720 adjacent to the toilet tank, the backrest is lowered to an upright backrest position as shown in FIG. 26, whereby the user can sit on the exposed toilet seat 700 with his back resting comfortably against the cushioned backrest.
Similar to the previously-discussed embodiments, the assembly can be positioned in a standing male urination mode with the backrest 720 in a raised substantially horizontal position and the toilet seat 700 in a raised generally vertical or a little past vertical position. (A less desirable configuration can be with the backrest sandwiched between the raised toilet seat and the raised lid, similar to the relationship of FIG. 23.)
A chair assembly of the present disclosure can be used as a medical device for people who are unable to stand from a seated position, moving to the bathroom and sitting on a toilet. This chair assembly can have the locking casters as shown in FIGS. 15 and 16. When the chair assembly is in a remote chair location the backrest, toilet seat and chair seat lid are in the relative position as best shown in FIG. 1 and the toilet seat is in the position as best shown in FIG. 19. When the chair is positioned over a toilet and in a toilet-use mode they are in the relative position as best shown in FIG. 14. This chair assembly can optionally be equipped with the reclining backrest capability as shown in FIG. 27 at 760. The equipment to move the backrest from an upright position to a releasable reclined position for example can be a lever which allows the amount of recline to be adjusted through a series of notches set at predetermined angles, or a turnable knob which allows the recline to be adjusted at a custom angle via a friction hinge.
A preferred embodiment of the chair assembly can include: the foldout footrest of FIGS. 5-7; the tilt-out side compartment of FIG. 6 on one side; the pullout compartment with lift-up and pivot tray of FIGS. 21A-C on the other side; the roll-out, fold-out tray of FIG. 8 on both sides of the chair; the telescoping legs with lockable casters of FIGS. 15-16; the curved frame with attachment point over the toilet tank, curved backrest and head rest of FIG. 22; the arms having the repositionable capabilities as shown in FIGS. 9A-C; the telescoping arms having the up-down positioning capabilities of FIGS. 14 and 21A; the lift-up toilet seat and lift-up backrest of FIG. 13B; the toilet-use mode of FIG. 14 with the backrest in the lifted position; the removable toilet seat of FIGS. 17-20; the half-length skirt of FIG. 21A; and the footrest of FIGS. 5-6 positioned at the higher position as shown in FIG. 21A.
Although the present inventions have been described in terms of preferred and alternative embodiments above, numerous modifications and/or additions to the above-described embodiments would be readily apparent to one skilled in the art. The embodiments can be defined as methods of use or assembly carried out by anyone, any subset of or all of the components and/or users; as systems of one or more components in a certain structural and/or functional relationship; and/or as subassemblies or sub-methods. The inventions can include each of the individual components separately.
