Glass globe doorknob is a whole-room fisheye for the other side of the door

Hideyuki Nakayama's glass globe doorknob refracts the scene on the other side of the door in its depths, giving you a preview of what's going on in the next room before you turn the knob.

  1. Should be mandatory in high-rise apartment doors for fire safety reasons. Don’t open that door in a fire situation until you’ve had a peek at the other side!

  2. Coming from a door-handle culture: door-know are an abomination before God and men and should should get wiped from the earth. Next to these tiny light switches the anglosphere is so fond of.

    Plus, they are not even cat-proof, which would be their only redeeming value.

    1. I guess I don’t get what is so awful about door knobs or wonderful about handles — I actually had to check to see which my current apartment has (handles). Aren’t they basically the same thing, only we call the roundish ones “knobs”?

  3. Woulnd’t mind one on the front door of my house but I’d want it to look out, not in. My door’s metal and I’m loathe to drill through it to install a peep hole, so this would serve that purpose of showing me who’s knocking on the door.
    But for interior doors, that’s just creepy.

  4. What peter said. Door knobs are an actively bad solution – especially in older houses where the bolt might stick a bit.

    This is very neat, though.

  5. I hate the round door knobs, they are very user-unfriendly. For example: If you carry something big and heavy, you cannot open such a door with your elbow. So you have to put the stuff down, open the door and pick up the stuff again. And it must be even worse for people that does not have a powerful grip like people with reumatism or similar.

  6. I think it’s awesome! If you just wanted it for fire safety purposes, perhaps it can be coated with something that will burn off at a relatively low temperature but otherwise is opaque. IANAMS (I am not a materials scientist).

    I think though a better use, since most people won’t want these in all their interior rooms, is to just replace the standard peephole with one of these. Then you don’t have to look into the tiny hole with bad optics – you’ve got this awesome orb to look at, probably even from several feet away.

  7. Ah, I guess i should have written “door-lever” , as both a handles, of course.

    Try to open a door knob with just your elbows.

    Also, a door knob requires more strength, as it offers less leverage and you have to twist your wrist more.

    I guess they are marginally better in case of zombie outbreaks, as the undead can’t work them, but I consider this to be a minor drawback.

  8. Not really new.

    The Victorians had glass doorknobs. The difference is that they used a brass shaft to connect the two knobs together (this is sounding a bit like a Carry On film now) so that you can turn the door catch. The difference here is that to allow you to see through to the other side a glass shaft is used.
