Abstract
A door operator having an automatic roller closes and opens a door attached to a doorjamb by a door hinge. The roller is actuated by a motor and housed within a protective roller casing affixed to the bottom of a door. The door operator may be integrated with a smart home, thereby allowing a user to close and open a door by voice command. The door operator may be retrofitted to existing doors. A door may also be modified such that only a magnet holds the door closed and a closed position such that the smart home door closing apparatus may be used to open a door. The roller may translate between an extended position engaging the floor below a door and a retracted position above the floor, either inside or adjacent to the door itself.
Claims10
A door operator having an automatic roller comprising:
- a roller engaged with a floor underneath a door, wherein the door rotates about a door hinge attached to a doorjamb of a doorway, and the roller has an axis of rotation substantially parallel to a width of the door and coplanar with an axis of rotation of the door hinge;
- a protective roller case at least partially enclosing the roller and attached to the door;
- a microcontroller inside the protective roller case;
- a motor regulated by the microcontroller which rotates the roller about the axis of the roller;
- wherein the door rotates to a closed position when the roller rotates in a first direction, and translates to an open position when the roller rotates in a second, opposite direction;
- and
- wherein the roller is spherical, and the roller and the motor are attached to a roller hinge, the roller hinge having an axis of rotation substantially perpendicular to both the width of the door and the axis of rotation of the roller.
