    Bathroom latch problem

    Bathroom latch problem 15th Jul 17 at 4:35 PM
    Once again guys, I need some help

    Hopefully there is a locksmith or someone who knows about the inside gubbins of latches. I bought a new latch, managed to dig out the hole in the door for it but then discovered that the catch was facing the wrong way. A quick google showed that it was simple to open up the latch and twist it round. Right, hmm, not so simple after all. A spring bit has pinged off and I cannot work out where it should be replaced. I can't even see what it's for but I'm afraid that if I leave it out I might end up like the 'old lady locked in the lavatory'! Is there any kind soul who can advise please?

    I'd hazard a guess that the circular portion of the spring goes on one of the lugs in the base, but which one, and what the ends rest against, is hard to tell. Is there another lug or similar on the upper part of the case that you've removed? The fact that it 'pinged' when you took the case apart indicates the spring was under tension, which might give a clue. If you put the handle/lock spindles in and turn them, do they return as expected?

    No, there are no lugs in the upper part of the case. I've tried putting the spring on the other lugs but I can't seem to make sense of what it is for.

    Looks like the spring should hold the the lock-bolt in the locked or unlocked position as necessary, otherwise it looks like the bolt would be free to slide about. For example when the door was pulled shut, is it possible the bolt could be free to slide and lock you out. If you were inside, not a problem as you could unlock it from inside.

    I'd need to be "hands on " to work it out.

    Edit: could it be that the spring should be fitted so it presses against the part that turns when locking/ unlocking? (to cause friction)

    Another edit: In the first pic the cam was in the wrong position. So with the cam in the correct position in the second pic, can you fit the spring so it presses against the cam somehow? This would give a positive lock/ unlock action.

    Remember, it will need to be fitted "under tension". Mind your fingers . . .

    I edited my post again after you'd posted, did you see the edit? I'll post it again:

    "In the first pic the cam was in the wrong position. So with the cam in the correct position in the second pic, can you fit the spring so it presses against the cam somehow? This would give a positive lock/ unlock action."

    No, I hadn't seen your edit but now I know what you mean about 'mind your fingers' Good job I'm wearing specs too, it keeps pinging off. I think I'm getting nearer, I just can't hold it in position and get the case back together. It wasn't like this on YouTube

    Just too late.
    Answer at the end . . .

    There are two independent mechanisms :
    1) A standard door handle latch, which is the wedge-shaped bolt ; bottom of upper picture, lower right of bottom picture
    2) A bathroom-specifc locking latch, which is the square-shaped slotted bolt ; top of upper picture, top left of bottom picture.

    It looks as though the mechanism is mounted face-on to the door, rather than recessed ; so failing everything else, a screwdriver could be used to remove it. Leave one obviously in the bathroom as an emergency.

    (1) is operated by a big handle on either side.
    (2) is operated by a big handle on the inside ; but there might be some small pin on the outside, for emergencies, which can be turned by a coin.

    (1) has 2 coil springs : one ( in the corner ) to put the handle back into its rest position, and one to push the wedge bolt into place. That means the spring belongs to the other mechanism.

    For (2), as societys child says, something needs to stop the bolt moving freely. Apart from anything else, it could slide across as the door is slammed shut, damaging something. Ideally it should force the handle / bolt to either the open or shut position.

    The Answer =

    From the bottom picture, turn the spring over, slide it onto the spike in the middle of the slotted square bolt, then imagining its two ( unequal length ) arms to be the hands of a clock, set it to about 10 past 12. The short end presses against the slotted retainer of the "normal" mechanism, while the long end presses against the "nose" of the "bathroom" square key. The "bathroom" latch should then try to stay at either end, not in the middle.

    Good luck Jim.

    Thanks Geoff1963. Now I'm not sure if I did actually place it as you describe. It does seem to work in that the lock is now sort of springy to move in and out and doesn't just fall out. The question is, do I risk taking it apart to check or do I leave as is and hope it's correct.

    It should be that as you move the locking handle round ( from locked to unlocked, or vice versa ), it gets gradually easier to about half way, then tries to pull itself all the way to the other end. If it's doing that, then it's probably OK.
    Imagine the internal locking handle is connected to an upside-down pendulum.

    If you do take it apart, get another photo.

    Aargh - saw this too late but I'm pretty sure now that I've got it back correctly. The only trouble is, it was all greasy inside and, with so much fiddling, the grease is now all over me and it is dry inside. Ah well, I guess it will work till it seizes up. I'm loath to take it apart again, I needed about four pair of hands to hold all the springs in position.

    Thanks again guys for your help.
