Rock-away

Abstract

The invention is a self activated spring supported rocking stool seat that assists in discharging the bowels, by bracing and empowering the hips and buttocks.

Description

ALTERNATIVE EMBODIMENTS

The common geometry of the Rocking-Toilet Seat remains the same configuration throughout. Methods of Manufacture match those of current toilet seats. The coil springs when inserted and provide the strength and flexibility needed.

BACKGROUND OF THE INVENTION

It is well known that dogs when relieving themselves, go through a series of pumping motions while walking, slowly, which enables the dog to gradually eject the stool from his body. In a similar manner, a person, will find relief by rocking front-to-back, or side to side, continuously, on a spring supported, stool seat, until the bowels are discharged. The “Rock-Away,” will be particularly useful to those adults, and children, subject to constipation.

SUMMARY OF THE INVENTION: THE ROCK-AWAY

a.) The device is clipped into place atop the toilet seat by sliding the clips into place. The Rock-Away can be readily lifted, and removed from the toilet seat by removing the 4 clips.

b.) The Rock-Away is designed to be light, compact, easy to attach.

c.) The four spring units and the stool seat will not be exposed since they are inside (2) layers of abrasive resistant nylon.

d.) The Rock-Away will have the same shape as the toilet seat.

e.) The Rock-Away may be used by both children and adults.

f.) The Rock-Away does not become soiled with feces or urine because it is located above and at a sufficient distance from the anus and the uretha.

g.) Both backward forward and sideward angular motion of the Rock-Away may be used alone or with assistance.

h.) For new water closet installations, wherein there is no existing toilet seat already in place, the Rock-Away's bottom seat will be extended 2 inches with bolts supplied, for a normal toilet seat connection.

COIL SPRING DESIGN

Assume torsional modules of elasticity.

Load=80 lb., Mean Spring Diameter=1.5″, C=11, 500,000 psi.

Assume allowable working stress's=60,000 psi $\begin{array}{ccc}d=3\frac{\mathrm{PD}}{0.3S}& & d=\sqrt[3]{\frac{80\#\times {1.5}^{″}}{\mathrm{.3}\times 60,000\mathrm{psi}.}}={\mathrm{.188}}^{″}\end{array}$ Try No. 6 wire=0.192 inches Find Wahl Factor $K=\frac{4C-1}{4C-4}+\frac{0.615}{C}$ Trial wire size $C=\frac{D}{d}=\frac{1.5}{\mathrm{.192}}=7.8\mathrm{inches}=\mathrm{Wahl}\mathrm{Factor}$$S=\frac{8\mathrm{PDK}}{{\left(d\right)}^3}=\frac{8\times 80\times 1.5\mathrm{.1}\mathrm{.19}}{3.1416\times {\left(\mathrm{.192}\right)}^3}=51,500\mathrm{psi}$ stress less than 60,000 psi

Use #7 Wire $f=\frac{{\left(8\mathrm{PD}\right)}^3}{G\times {\left(d\right)}^4}=\frac{8\times 80\times {\left(1.5\right)}^3}{11,500,000\times {\left(0.177\right)}^4}={0.191}^{″}$

Assume clearance between loaded coils={fraction (1/16)}″Then Pitch=L=B+f+d={fraction (1/16)}″+0.0191+0.192″=0.444″Clearance=L−f−d+0.444″−0.191−0.177″=0.076″

Assume solid Length is less than 1{fraction (7/16)}″ $\mathrm{Number}\mathrm{of}\mathrm{coils}=N=\frac{h}{d}=\frac{{1.43}^{″}}{{0.177}^{″}}=8\mathrm{active}\mathrm{coils}$Therefore Solid Length=h=8×0.177=1.4″Free Length=H=8×0.444″=3.5″Pitch L Per Coil=of Loaded Spring=1 Pitch 1 per coil=L−f=0.444−0.191=0.253″/coil

Assume Hw=2.5″ and end coils are squared. $N=\mathrm{number}\mathrm{of}\mathrm{active}\mathrm{coils}=\frac{\mathrm{Hw}-3d}{1}=\frac{{2.5}^{″}-3\times \mathrm{.177}}{\mathrm{.253}}=8\mathrm{coils}$

When N=8 H=8×0.444″+3×0.177=4.1″Total Deflection=N=(L−d)=8(0.444″−0.177″)=2.136″

Working load: Working Deflection: Maximum Load: Maximum Deflection Maximum Working Load=2.136″×80 lb/1.53″=112 pounds

Solid height load $P=\frac{11,500,000\times {\left(0.177\right)}^4\times 2.136}{8\times 8\times {\left(1.5\right)}^3}=112\mathrm{pounds}$

Working Stress: Maximum Stress: Working Deflection: Maximum Deflection $\mathrm{Maximum}\mathrm{Stress}S=\frac{64,500\mathrm{psi}\times 112\#}{80\#}=90,000\mathrm{psi}$

The Ratio of Mean Spring Diameter to Wire Diameter, i.e., the “Spring Index” should be between 6 and 9, wherein 9 is ideal.

Claims

1. The Rock-Away will ease bowel movements through the rocking activity as controlled by the user, or by an assistant.

2. On those installations where new water closets are being installed, the bottom seat of the Rock-Away will be extended 2 inches and bolted directly to the water closet installations, as are toilet seats presently attached.

3. An additional water closet lid will be provided to close-off the water closet when not in use, on new installations, by lengthening the hinges two inches, in order to fold over and close off the Rock-Away openining.

4. For children and handicapped adults, a moveable Rock-Away chair, with casters, will facilitate the activity described in claim 1, and at the same time provide for mobility of the chair, plus removal of wastes.

5. Long periods of time can be spent in the Rock-Away Chair getting plenty of exercize, due to horizontal movement, particularly for the lower leg muscles, where clots-causing strokes due to inactivity originate, and partially eliminate the need for diaper changes.

6. Independent Claim: The invention is a toilet seat for encouraging human bowel movements comprising vertically spaced base and seat members which bound a thorough evacuation passage; and means of supporting the seat member on the base member which allows the seat member to rock relative to the base member as the weight of the human occupant is shifted back and forth.

7. The seat of claim (6) wherein the supporting means is defined by sets of 4 coils, compression springs, whereby the seat member may shift laterally as well as rock vertically to the base member.

8. The seat of either claim (6) or claim (7) wherein the base member is adapted to rest upon the existing seat of a toilet; and which includes shiftable attaching means for securing the base member to said existing seat.

9. The seat of any one of claims 6-8, includes a protective cover of elastic material enclosing the base and seat member, and the supporting means.

10. Long periods of time can be spent on the Rock-Away, getting plenty of exercise, due to front to back as well as side to side movement, particularly for the lower leg muscles where clot-causing strokes due to inactivity originate.

11. This Rock Away should lead to a rapid decline in testing for and performing Colostomys prescribed by doctors.

12. Very little toilet tissue would be utilized because the bowel movement would ordinarily not stain the anus.
