Is there a lock app that locks from the notification bar?

I don't want my phone locked at home. I would like to have an app that leaves the screen unlocked until I lock it again. But I would like to be able to touch an icon in the notification bar to lock it. Is there such a creature out there? I haven't found what I'm looking for so far. Thanks!

You might search Playstore for a wifi unlocker app. These apps will unlock your phone when a certain wifi is detected... like your home wifi. I don't use any, so I don't know how reliable they are. HERE'S one from playstore. I believe a lot of them are paid apps.
