We had a USA client come up with an idea. He wanted a compression gas spring that could be applied to the sofa with a locking function. But he doesn't want additional control accessories like lockable gas springs.
This means there is no control handle to control/lock the gas spring. The gas spring needs to lock itself inside when the back of the sofa stops in a certain position.
Based on the principle of a press-type ballpoint pen, JP designed a self-lock compression gas spring to help customers solve the problem.
