Spring loaded level/handle

[KKerr23]

I have a current design that I wish to use a spring loaded lever that can be pulled out in order to obtain different locking positions with a set pin. I know I have seen these types of levers used in other systems but my research has come empty trying to find a company that fabricates these. Are there any companies that do make spring loaded levers or is it something I will have to design from scratch?

Carr in St. Louis specializes in the weirdest clamps I have ever seen!!

I think Fairlane Products is the manufacturer that makes those handles in the reid supply link I gave.

It is similar to the products in those links, but those are mainly for lockling pins. What I am talking about is an actual lever where the handle is spring loaded so that you can pull the handle out to unlock and release to lock. My idea is to add a set pin to the side of this type of lever and use the set pin to lock into a set of teeth. I have seen these types of levers around but I have no clue who would make them.

You mean like a handbrake?

 

[KKerr23]

Not like a hand brake. Like with a spring loaded pin you would pull up the handle to pull the pin out then release to lock it back into place. Instead of the pin locking into a hole, I am installing a set pin on the side of the base to align in a set of teeth

Eh. Kind of like that. Instead of the clutch on the bottom of the lever, it would just be a matter of pulling the handle out axially wrt the shaft to adjust the position of the lever

Like a pop pin?

Ergonomically/mechanically your proposal is likely to be tricky to get working satisfactorily. The Off axis torque on the sliding joint as the operator attempts to pull the handle along it will tend to casue it to bind. I have seen what you propose, but they use a knob not a handle, so there is no off axis torque.
