FingersKeeper : The World’s First and Only Automatic Door Slam Protector
Let us present to you the FingersKeeper - the first and only automatic door slam protector.
What triggered us to work on FingersKeeper were a few unfortunate incidents around us where children hurt their fingers by slamming doors. After a research on existing products, we saw the need for a product that protects people from door slams while not interfering with people’s daily lives.
As a team of people with various industrial backgrounds and engineering in our bones, we quickly came to the decision of designing such a product ourselves. After years of perfecting our design, we are now ready to introduce to the world FingersKeeper - the world’s first and only automatic door slam protector.
Automatic Reaction to Door Slam
FingersKeeper does not interfere with the opening and closing of the door in normal use. It only goes into action when the door slams at a higher speed than the speed FingersKeeper is set to detect. Once detecting a door slam, FingersKeeper reacts instantly, creating a gap between the door and the frame.
Another important benefit you get from using FingersKeeper is eliminating the bad habit of slamming doors.
How Does It Work?
Now let’s take a look at the physics behind FingersKeeper that allows it to do its magic.
The picture above shows the inside mechanism of FingersKeeper. In normal use of the door, gravity holds the door stopping arm in vertical position, not interfering with the door. In the event of a door slam, the arm will impinge against the diagonal slope, and the door's linear acceleration will be converted to side movement of the arm. The door stopping arm will stick out of FingersKeeper's case, jamming the door and creating a gap between the door and the door frame. Once the arm is out of the case, the magnet on top of the door stopping arm will attract the metal bracket and keep FingersKeeper in the door jamming mode. A quick push on the arm will re-position it inside the case, resetting FingersKeeper and arming it for the next door slam.
FingersKeeper is a patented design. We spent years to perfect the product, designing it from the highest quality materials. Now it is ready for production. We need your help to introduce it to the world and protect the children around us.
FingersKeeper is smaller than most smartphones. It is only 4” (10cm) tall, 2 ⅝ “ (6.7cm) wide, and 2 ¼” (5.7cm) thick.
3 Color Schemes
We carefully selected 3 color schemes for FingersKeeper: brown, black and beige. Based on the theme of your house, you can always find one FingersKeeper that fits your door perfectly.
