My application needs to have a rail like sliding system but also needs few other properties

  • Vertical Slider
  • Range Lock
  • Range Lock should be adjustable

I've sketched the requirements for better understanding.

Locked state 1

Slider should not go below minimum lock position

Minimum Height Locked State Picture

Locked state 2

Slider should not go above maximum lock position

Maximum height locked state picture

Maximum and minimum lock positions should be adjustable

Range 1

Range 1

Range 2

Range 2

Specifics about use case

  • The force will be from the top and not more than 25 kgs
  • The slide up and down motion will be used 20 times a day
  • The slide range adjustment will be used 5 times a day
  • Maximum height lock need not support weight from above, although additional support is a plus
  • Minimum height in normal state is 28 inches
  • Maximum height in lifted state should be upto 46 inches i.e 18 inches taller

I'm not familiar with different types of slides or hardware for the job.

What are the types of hardware required to accomplish the task efficiently.

  • Is this in some why related to home improvement? - I'm not seeing any sign that it is for the question as it stands - a "slider?" – Ecnerwal Sep 11 '14 at 2:45

    @SathishManohar That's the question you should be asking. Present us with the problem you're trying to solve, (adustable height shelf). You're narrowing the scope of potential good answers by limiting the solutions. Who knows? Someone may have already solved this problem in a completely different way. – Chris Cudmore Sep 11 '14 at 12:32

    Are you trying to make an adjustable shelf? Or a desk that you can adjust so you can sit or stand? – longneck Sep 11 '14 at 13:09

    @ChrisCudmore Will broaden the scope of the question. Thanks for the suggestion. – Sathish Manohar Sep 11 '14 at 13:52

    Can you also explain the difference between the two heights? Is this to raise lower a couple of inches or a couple of feet? – treeNinja Sep 11 '14 at 14:10
