Introduction: Toilet Assist

This Instructable is more of a presentation, or an example, of a device to solve a problem.

There was a real need for such a support device to assist my wife in helping her with the task of sitting on the toilet. For many this is not a concern, but for her and many others, it is.

For starters, I purchased a stand for the toilet that raised it 3 1/2 inches. This made life a lot easier for both my wife and her mother. I must say that I even got to like it too. But this was not quite enough for them. There was a need for some way of using their arms for lowering themselves.

I did a fairly good search for such an aid. Many I found were not, in my opinion, sane, safe and responsible. Several were to be secured to the toilet, transferring the users weight to the toilet in a manner that the toilet was not designed for, a very poor design. I did find one that did transfer the users weight to the floor, straddling the toilet. It even folded up. I still felt I could design one using PVC that would suffice. I must admit that I did not perform a stress analysis for the one I found or for the one I designed with PVC. I did, however, test the stand with my own weight, bouncing a little, to create a greater loading, and saw very little deflection.

It made life much better for my wife. My mother-in-law really liked it too.

Step 1: Design for Us

Picture of Design for Us

These drawings are of the one for our older, more rounded, toilet.

I've shown the points that are to be adhered to.

The design uses 1 inch PVC, except for one critical area. When the toilet lid is up there is limited space behind and just above it. Here, I used a piece of 3/4 PVC here with reducers.

Step 2: Elongated Toilet Bowl

This design is for an elongated toilet bowl.

It's depth is a little greater, and so the arms are a little longer. Since this will have higher stresses than the one I designed I cannot be responsible for possible failure.

I leave this up to those that may build this one.

A way to reduce the stress would be to use, say 1-1/2 PVC, for the arms, both upper and lower. This would require the need of reducers at the front and rear. The larger arms would also feel better to the users. I had considered that even with mine.

Yes, using reducers at the front and back, will be be structurally sound. The stress is a maximum at the point where the hand will be. Bending stresses will be a minimum here. At the front and back, the major concern is shear stresses and they should be adequately handled. Arm deflection ( a result of bending stresses), although small, would be transferred to the legs. The legs should be able to handle this.

Step 3: Final Remarks

I, or another engineer, should do a stress analysis on both designs.

I, therefore, cannot condone the structural integrity. I cannot be held responsible for any injury incurred from a structural failure.

As such, builder, beware.
