Discussion Overview

The discussion centers around the search for foot-operated fasteners that can replace traditional screws and bolts. Participants explore various mechanisms that could secure and unsecure items using foot action, considering potential applications and designs.

Discussion Character

  • Debate/contested
  • Exploratory

Main Points Raised

  • Some participants suggest adapting existing foot-operated devices, such as those found on hospital beds or quick-release mechanisms used in bicycles.
  • One participant mentions a cam clamp on a table saw as an example of a foot-operated mechanism.
  • Several participants express the need for more specific details about the application to provide relevant suggestions, highlighting that the current question is too vague.
  • There are mentions of various potential solutions, including pull solenoids with footswitches and toggle or ratchet clamps, but these are contingent on specific application requirements.
  • Some participants express frustration over the lack of clarity in the original question, suggesting that without more information, it is difficult to provide meaningful responses.

Areas of Agreement / Disagreement

Participants generally agree that the original question lacks sufficient detail, leading to confusion and frustration. Multiple competing views on potential solutions are presented, but no consensus is reached regarding the best approach.

Contextual Notes

Limitations include the absence of specific application details such as size, force requirements, orientation, and other parameters that would influence the choice of fastener.

Hello,

Are there any fasteners that can be fit instead of normal screws and bolts and can be secured/unsecured via foot?

I was thinking something that you step on and it secures and you then use a lever or handle to unsecure it.

Is there anything like that?

Only thing I can think of is that some hospital beds have foot operated devices to stop the wheels rotating and the bed moving. I suppose something like that could be adapted.

Perhaps "over centre" devices like those used on quick release bicycle wheels could be foot operated.

Can you describe the application? That might be a better way to get good responses... :smile:

That's an extremely vague question. I agree w/ berkeman ... we need to understand the application
 
I have a cam clamp on the bottom of a table saw, that is foot operated.

@physea we are all going to just keep wasting our time guessing, waiting for you to explain yourself better. How about you do that?

I don't understand why my question is not clear enough.

I want to replace a screw+bolt with something that fixes/unfixes by foot.

So it's totally irrelevant where the screw/bolt are? Doesn't matter how high off the ground they are? Doesn't matter how big they are (# 4 screw for example, vs a 1" diameter bolt)? Doesn't matter whether they are mounted at an angle to the horizontal, or for that matter are vertical? Nothing matters except that you have some very vague requirement which you somehow believe is a sufficient problem statement. Good luck with that.

Because there are perhaps dozens of different ways to go about it, but many of these approaches won't be applicable. For instance, a pull solenoid and footswitch may be just the ticket provided an electrical source is available and the 'screw replacement' locks a detent shaft in place, but totally inappropriate for other applications.

There are likely thousands of fasteners that meet your vague description and which is best for you depends on all the details of your application you haven't told us. How big? How much force? Through or around? What orientation? Tension or shear? Rotation? There are probably at least a dozen parameters, which is why there are so many fasteners.

Some car trunks are operated by waving your foot under a sensor. That's my choice.

'Toggle clamp' and 'ratchet clamp' gives some interesting google results in the category of 'close enough' or 'it can be used so', but without further details...

I don't know about the rest of you (well, except for @phinds :smile:) but I'm done with trying to help this OP with his super-vague question and attitude. I'm Unwatching this thread...
