Gate latch/opener design? Answered
I'm building a fence and having trouble figuring out how to do the latch for a walking/utility gate. I want the fence to be almost seamless from the outside, so with a quick glance you couldn't tell there is a gate right there; however, the gate needs to be able to be opened from the outside with a key.
The problem I'm having is that all the hardware I've found for gates use padlocks, so you could only open it from one side if it's locked, and the gate won't be thick enough to use a normal door handle or deadbolt.
The parameters are:
Opens from inside while locked from outside
Outer hardware is minimally intrusive (doesn't stand out much, preferably nothing more than a key hole.)
Actual latch can be surface mounted
So far the only thing I've been able to come up with is to frankenstein the key half of a deadbolt with half of a turn handle latch I found that forks like a regular door knob but can be surface mounted. The problem is that I am afraid that the spring in the handle will be too much tor just the key to turn and it will wear out quickly.
I would appreciate any ideas, and will try to clarify if there's anything someone doesn't understand.
