I decided to use a frame of aluminium slot profiles and 3D-printed cuffs. This way I can draft all parts on the computer and just have them created without any manual processing. All printed parts are parametrized and can be adapted to different proportions. The slot profiles form a rectangle. The note plates will only be unscrewed on the side with the alignment helpers. This significantly reduces setup time after the correct positions have been found the first time.
The alignment helpers will keep the nuts at the right position and provide a centering aid for the plates. This way, one corner can be connected in about 30 seconds. The bottom cuff will be connected to the profile with the M5 screws.
The M8 screw is used as a hinge. Since the top part of the cuff will move relative to the screw, it is advisable to reduce wear by using a screw which only has threading at the top. To lock the cuffs, either a second M8 screw or a padlock with a long shackle can be used. For two reasons the neck is handled differently than feet and hands: Firstly, a fixed neck position gets uncomfortable very quickly.
Secondly, and more importantly, it would be a high risk in emergency situations like a circulatory collapse. The snap shackle is meant to hold a collar or a chain to a collar. A snap shackle can be opened without moving the neck back to the floor in contrast to a carabiner.
It is not a panic snap, though, and not designed to be opened under pulling stress! The same principle could also be used to attach other cuffs for the feet, to allow more freedom of movement and more comfort. It is not suitable for the hands, because the shackle could easily be opened. It basically means, that failures should only make it easier to escape, never harder. I use a battery-powered magnet that directly holds the cuff closed. This will ensure that at some point in time you should choose your battery accordingly the magnet will go off, no matter what.
Since electromagnets can retain a certain amount of magnetization, it is important that the magnet applies a force opposite to the opening direction. So if permanent magnetization occurs, the weak remaining force can be overcome with muscles. This requires a certain placement of the magnet, which I did not know how to achieve with commercially available cuffs.
This has been the main reason to use custom cuffs, which provide the necessary connection points for the magnet. Since making the code for all parts available in a usable way would require a lot of additional work, I will not upload it for the moment. If you want to build it yourself, feel free to contact me, I will gladly help out! Du kommentierst mit Deinem WordPress. Du kommentierst mit Deinem Google-Konto.

The floor pillory was planned according to the following criteria: Everything can be built without any manual processing of parts. The cuffs can be placed freely on the frame. The whole pillory can be split into parts for transport and storage as fast and using as few tools as possible. The whole construction is sturdy enough for a normalized human being me.
The locking mechanism is suitable for selfbondage. There should be room for further modification.
