Spring Hinge Solutions for Unique Jobs

Click For Summary

Discussion Overview

The discussion revolves around the design and functionality of spring hinges for specific applications. Participants explore the requirements for a spring hinge that can lock at 90 degrees and potentially open to 180 degrees, while also considering various mechanical constraints and locking mechanisms.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the feasibility of a spring hinge that can lock at 90 degrees and return to a closed position, questioning if it can also open to 180 degrees.
  • Another participant asks for details about the application, including load requirements, design specifications, and quantity considerations, indicating that these factors are crucial for hinge selection.
  • A participant references a patent related to spring hinges, noting issues with accessing the drawings and suggesting that reviewing the patent could provide useful insights.
  • Discussion includes considerations about the locking mechanism, with a participant highlighting the importance of the release sequence and mentioning hinges that can open beyond 360 degrees, although they may have limited applications.

Areas of Agreement / Disagreement

Participants express varying views on the design and functionality of spring hinges, with no consensus reached on specific solutions or mechanisms. The discussion remains open-ended with multiple considerations presented.

Contextual Notes

Participants have not fully defined the application requirements or constraints, and there are unresolved questions regarding the locking mechanism and its operation.

Spring hinges..?

I need a spring type hing to do a particular job. From a closed position when in use it can be pulled open to 90 degrees and locks in position. Then can be released to spring back to closed position? Also could one open to 180 degrees?...is this possible?

thanks

It's all possible. What's your application? What loads do they need to take? Are you designing them or specifying them? Are you buying large quantities? What other constraints are on your selection?
 
Another consideration is how you want the locking mechanism to work, especially what sort of release sequence you want. (Just apply extra force, or have to manually pull some sort of trip system?)
I've seen hinges that almost defy imagination; you can get them to do just about anything. Some will open to over 360 degrees, although they are pretty much limited in applications.
