Interactive door knob
View Patent ↗A door knob assembly that provides an interactive visual and aural assembly familiar to a room occupant and that responds to variations in the manner of rotation of the knob in a plurality of responses, depending on the direction and rate of rotation applied to the knob, providing messages appropriate to the entertainment, safety and/or training of the knob operator and/or room occupant.
1 . A door knob assembly comprising;
one or more knobs;
a spindle or shaft connected to said one or more knobs, said spindle extending through a deadlatch mechanism for door latch actuation;
knob rotation sensing components coupled to said spindle, said knob rotation sensing components comprised of two tilt switch sensors plus electronics components capable of determining the rate of rotation of said knob based on the difference in time in activation of each said tilt switch sensor; and
a power source.
2 . The door knob assembly of claim 1 wherein;
said electronic components activate the sound features of the system when said knob said knob is rotated at a rate faster than a predetermined rate.
3 . The door knob assembly of claim 2 wherein;
said door knob assembly is equipped with Light Emitting Diodes (LEDs) and/or speakers driven by said activation stage electronic component's activation, so that power up and rate of rotation and/or direction of rotation may be used by the system electronics in generating one or more pre-determined audio and/or visual responses.
4 . The door knob assembly of claim 1 wherein;
said tilt switch sensors are asymmetrically angled.
5 . The door knob assembly of claim 4 wherein;
the first tilt switch sensor is mounted so that when the board is at rest, said first tilt switch sensor is angled at half the angle of the second sensor.
6 . The door knob assembly of claim 5 wherein;
the first tilt switch sensor is mounted so that when the board is at rest the first tilt switch sensor is angled at 22.5 deg. and the second sensor is angled at 45 deg.
7 . The door knob assembly of claim 6 wherein;
said electronic components activate the sound features of the system when said knob said knob is rotated at a rate faster than a predetermined rate.
8 . The door knob assembly of claim 7 wherein;
said door knob assembly is equipped with Light Emitting Diodes (LEDs) and/or speakers driven by said activation stage electronic component's activation, so that power up and rate of rotation and/or direction of rotation may be used by the system electronics in generating one or more pre-determined audio and/or visual responses.
