Hello, I want to design a mechanism for tilting an air hose (not more than 10 kg) to a desired angle (anywhere between 0 and 90 degrees depending on operating conditions) and holding it there. I've tried googling this up but just can;t find what I was lookin for. Then I searched for the tilt mechanism of laptop screens but I get results for tilting mechanism patents so not much use there..... Anyone able to suggest resources or links for different types of tilting mechanisms available and the locking methods? Esp for the tilt mechanism for laptops where YOU DON'T HAVE TO LOCK the screen in position...you move it to whatever angle you want and it stays there nicely....... Cheers!
