Why lockable chain window winder??

[Wongo]

Can a wiser person tell me the propose of a lock on a chain window winder?
When it is locked the window cannot be opened or closed. Why?

So the baddies cam't get in

That is what I do not understand. When the window is closed it cannot be opened from the outside whether there is a lock or not.

Hi,
So that the ankle biters can not mess up the ventilation flow.

We have that style of chain window winder with lock - I think you'll find it is possible to lever the windows open from the outside when not locked. It would require considerable leverage (e.g. a crowbar), but can be done, at least on the design we have.

I have the same question as the winders they replaced did not have locks.

Thanks

I have one in the house. I hate it because it is too easy to lock it accidentally and too hard to find the key.

If left a little open, they can be pulled open, with effort. It's how I used to get into Mum and Dad's when I forgot my keys.

After being robbed last year (window jimmied open) I had the choice of putting window locks on all windows or cop a large premium increase.
As I have winders at the back of the house and the bathroom, I asked the same question as the winders replacements for the bathroom cost a bomb and also meant I had to rebuild sections of the sill dressing!
The answer was that people like to leave winder windows partially open for air flow and a thief can get their hand in and wind the window fully open and get in at night when people are sleeping, You can lock the winders in a partially open position. My statement that they would have to be a very thin thief to squeeze in through the window even when it was fully opened was not well received.

Thanks. It makes sense now.

I can't believe this is the best design they could think of for a cheap and practical window opening mechanism. It's terrible. Unless there is something better out there and we are the terrible house owners who select this one. But I'm guilty as well, I searched and this was all I could find, and I installed it, and I hate it with a passion LOL

I have one in my house. The lock button is in the way so the winder gets locked accidentally all the time.

[Skew ChiDAMN!!]

Terrible design, agreed.

But I can understand the market being driven by insurance. Sadly the insurers don't seem to look at actual effectiveness, just so long as the word "lockable" is involved.

eg. Quite a few years back I was living in a high-risk area, in an old house with old sash windows all 'round. I drilled through both sashes in each window and tapped for M4 bolts. These were solid, although I did need to keep a small shifter handy if I wanted to change the openings.

However, I couldn't get the house contents insured until I replaced them all with commercial pins, which served the same purpose.... sort of. Except that the pins were narrower, as the whole thing, body and all, fitted in the holes I'd made for the bolts. Worse, once I didn't align the sashes properly and bent the allegedly toughened pin by simply trying to push it in.

Still, even though these were in no way as strong as my original M4 bolts, the insurer was then happy to cover me.

I guess they feel we must give the bugglars a realistic chance to break in before they'll provide cover.

The windows in my bathroom are casement windows and the winders move a set of arms so the window can be locked in any position from closed to wide open (90o).
Actually not a bad system - better then the chain type.
The lock, however, is a joke! It’s a tiny pin that goes into the end of the handle but it meets the insurance criteria so if their happy, I’m happy.

Hi,
Actually it,s all a joke as windows can be broken.
Or they could ram raid your house.
