DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, FIG. 1 illustrates a mobile sanitary bedside commode 10 in accordance with the present invention. The bedside commode 10 is generally comprised of a wheeled frame structure 12 having an uppermost portion attached to a toileting platform assembly 14.
The wheeled frame structure 12 includes a pair of left and right, spaced-apart, U-shaped frames 16 having uppermost horizontal sections 18 joined to an underside of the platform assembly 14. Each frame 16 has a front tubular upper leg portion 20 and a back tubular upper leg portion 22, both of which are formed with a plurality of vertically spaced holes 24. The front and back tubular upper leg portions 20, 22 on each frame 16 are telescopically received in a front tubular lower leg portion 26 and a back tubular lower leg portion 28, respectively. Each of lower leg portions 26, 28 are provided with a swiveling, floor-engaging caster wheel 30 which provides for mobility of the commode 10 in all directions of movement. Certain of the wheels 30, preferably those on the back lower leg portions 28, are provided with rearwardly oriented clamping or braking devices 32 which extend upwardly along the leg portions 28 for easy access to the hand of a user of the commode 10. The braking devices 32 are intended to stabilize the commode 10 when it is not being transported from one position to another. The frame structure 12 supporting the platform assembly 14 is made height adjustable by inserting pins 34 through holes 36 formed on the lower leg portions 26, 28 that are aligned with desired holes 24 formed on the upper leg portions 20, 22. With this construction, the platform assembly 14 can be set at a height level with the top and side of a user's bed.
The platform assembly 14 includes a generally rectangular platform 38 having a back end 40 adapted to be positioned adjacent a user seated on a bed, and a front end 42 spaced from the seated user. The front end 42 includes a pair of rounded corners 43 that form a gripping arrangement to be grasped by a user's hands during use. The platform 38 is formed with a toilet cutout 44 (FIG. 4) therethrough which is aligned with a sanitary waste container 46 that is removably mounted in a retainer 48 fixed beneath the platform 38. The cutout 44 includes a forwardly opening portion at front end 42. In the preferred embodiment, the sanitary waste container 46 is a cylindrical vessel that is equipped with a sliding door 50 which can be opened and closed as desired by the user. A toilet seat 52 is pivotally secured to the platform 38 by a hinge 54 located near the back end 40 of the platform 38. The toilet seat 52 is provided with an opening 56 that overlies the platform cutout 44 and includes a forwardly opening recess 58 at its front end. The toilet seat 52 lies above and is generally coextensive with substantially the entire width and length of the platform 38 as seen in FIG. 3. The toilet seat 52 is normally in a down position lying on top of the platform 38 when in use as seen in solid lines of FIGS. 1-3. The toilet seat 52 may be pivoted upwardly (as shown in phantom lines in FIG. 1 and solid lines of FIG. 4) when it is desired to access the sanitary waste container 46 from its retainer 48. It should be appreciated that the toilet seat 52 defines one sliding support surface during use of the commode 10 as will be understood hereafter. It can also be seen that the top of the platform 38 lies beneath the top plane of the toilet seat 52 as seen best in FIG. 2.
A ramp arrangement 60 is pivotally mounted about a rod 62 at the back end 40 of the platform 38. The ramp arrangement 60 is pivotable between a vertical, downwardly suspended storage position (FIG. 2) and a horizontal bridging position (FIG. 3). The ramp arrangement 60 defines a bridge and another sliding support surface between the platform 38 and the edge of a bed to facilitate use of the commode 10. The frame structure 12 is adjusted to a height which will cause the platform 38 and the ramp 60 to be substantially level with the top of a bed.
Use of the mobile bedside commode is depicted in FIGS. 5-9. A user U seated on the edge of a support surface such as a bed B with his/her feet on or adjacent the floor F accesses the commode 10 by positioning the frame structure 12 and the back end 40 of the platform assembly 14 adjacent the bedside. In the course of pulling the commode 10 toward the seated user U, the ramp arrangement 60 is pivoted from the vertical storage position to the horizontal bridging position so that the ramp arrangement 60 overlies the edge of bed B as shown in FIG. 6. The user U may then set the braking device 32, to stabilize the commode 10. At this point, the user U straddles the rear of the frame structure 12 and leans forward grasping the front end 42 of the platform 38, preferably at the front corners 43 thereof. The user U then pulls one's buttocks forwardly along the ramp arrangement 60 and the toilet seat 52, as seen in FIG. 7, until the user U is in an upright sitting position (FIG. 8) at which time the toileting function may occur. Following use of the commode 10, the user U again leans forward slightly lifting one's buttocks and pushes rearwardly while grasping the front corners 43 of the platform 38 in the straddled position. The user U slides rearwardly along the toilet seat 52 and the ramp arrangement 60 back onto the bed B as shown in FIG. 9. During use of the commode 10, it should be appreciated that the user U may slide freely back and forth using the front corners 43 or front end 42 as an anchor point without any obstructions rising from the toilet seat 52, or extending from the frame structure 12 or platform assembly 14. If desired, the commode 10 may be used to provide transport from one location to another.
Following use, the user may lift up the toilet seat 52 so as to remove the sanitary waste container 46 to empty and clean same.
In an alternative design shown in FIG. 10, the commode 10 could be used to transport a user to and from a conventional toilet seat TS of a toilet T in a bathroom. In this design, a horizontal mounting member 64 extends between lower leg portions 26, 28 on each side of the commode 10. A propulsion wheel 66 having a diameter which is substantially larger than caster wheels 30 is rotatably mounted to the center region of each horizontal mounting member 64. The bottom of each wheel 66 engages the floor F, and the top of each wheel 66 is engageable by the hands of the user U when seated on the commode 10. The larger diameter wheels 66 are positioned so that they do not protrude from the sides of the commode 10. This allows the user U to again slide freely back and forth onto the toilet seat 52 without any side obstructions. The center of each wheel 66 may be connected together by a cross member 68 to provide stability for the device. This design thus functions similarly to a wheelchair and allows a user to propel himself (herself) with their feet and/or with the use of their hands propelling the wheels 66 along the floor F. This is a particularly advantageous feature to enable a faster, easier transport of the seated user U, especially one who may have a foot or leg handicap.
In the FIG. 10 embodiment, a user U would mount the commode 10 in the manner described above. Then, the user U seated on the commode 10 would propel himself (herself) along the floor to a bathroom, positioning the back end 40 of the platform assembly 14 at the front end of the toilet T. The ramp arrangement 60 can be pivoted to the horizontal bridging position so that the ramp arrangement 60 is aligned with and overlies the toilet seat TS. Upon setting the braking device 32 to stabilize the commode 10, the user U then pushes and slides oneself backwards onto the toilet seat TS of the conventional toilet. After the toileting function is complete, the user U then grasps the front end 42 or corners 43 of platform 38, and slidably pulls oneself forward across the ramp arrangement 60 and back onto the toilet seat 52 of the commode 10. The user U then transports oneself back to a bedside B or other resting position by means of the wheeled commode 10.
It should further be understood that the commode 10 may be used generally as a transport device to move a seated user U from one position to another, if desired.
The present invention thus provides a bedside commode which provides for long term, unassisted, easy mounting and dismounting, and is particularly useful for elderly persons who wish to have their continued independence and maintain greater self reliance. Use of the commode requires minimal limb strength and relies instead upon a convenient, unobstructed, sliding on-off motion.
While the invention has been described with reference to a preferred embodiment, those skilled in the art will appreciate that certain substitutions, alterations and omissions may be made without departing from the spirit thereof. Accordingly, the foregoing description is meant to be exemplary only and should not be deemed limitative on the scope of the invention set forth with the following claims.
