Need a push to open/lock mechanism

Need a push to open/lock mechanism

(OP)
Have a design which has an 8" x 8" x 5" deep box that has to raise 3" from full close to full open.  I am looking for something like that used on audio cassette doors, only it raises straight up and down not pivot on a hinge.  Does anyone know of someone who makes something like this.

RE: Need a push to open/lock mechanism

You can get touch latches or touch catches from your local hardware store or furnitue shop.  You can also get them from McMaster-Carr for about $4.  
I am going to guess that a constant force spring (like in a lawn mower pull start)might be the best way to supply the force you need which you can also buy many places one of which is McMaster-Carr for about $7 to supply 4 lb of force.  The 3" stroke is not to long a travel for a regular spring but the constant force spring would fit in a much smaller footprint.
As far as drawer rails you can get them about anywhere.
