Abstract

A motor driven locking mechanism including a door hingably coupled to a door frame at a first side edge thereof, the door having a horizontally orientated channel with a first open end situated on a second side edge of the door opposite the first side edge and a second closed end and a door knob rotatably coupled to the door about an axis which extends above and perpendicular to the channel; a first locking mechanism including a locking rod for slidably inserting within the channel, a strip gear longitudinally situated on a top edge of the locking rod, and a motor located adjacent the closed end of the channel having a rotor extending therefrom with a bevel gear coupled thereto, the bevel gear in threaded engagement with the strip gear for situating the locking rod in an extended orientation with the locking rod engaged with the door frame upon the receipt of a lock signal and a retracted orientation with the locking rod residing only within the channel upon the receipt of an unlock signal; and actuation mechanism adapted to selectively transmit an unlock signal to the motor and further selectively transmit a lock signal to the motor.

Claims

1. A new and improved remote control motor driven locking mechanism comprising, in combination:

a door with a rectangular configuration having a front face, a rear face, and a periphery formed therebetween, the door hingably coupled to a door frame at a first side edge thereof, the door having a horizontally orientated channel with a first open end situated on a second side edge of the door opposite the first side edge and a second closed end and a door knob rotatably coupled to the door about an axis which extends above and perpendicular to the channel;

a first locking mechanism situated between the front face and rear face of the door, the first locking mechanism including a pair of guides each with a generally U-shaped configuration each longitudinally positioned along opposite side edges of the channel, a locking rod having a pair of elongated protrusions situated on opposite side edges thereof for slidably inserting within the guides of the channel, a strip gear longitudinally situated on a top edge of the locking rod, and a motor located adjacent the closed end of the channel having a rotor extending therefrom with a bevel gear coupled thereto, the bevel gear in threaded engagement with the strip gear for situating the locking rod in an extended orientation with the locking rod engaged with the door frame upon the receipt of a lock signal and a retracted orientation with the locking rod residing only within the channel upon the receipt of an unlock signal;

a second locking mechanism also situated between the front face and rear face of the door, the second locking mechanism including a vertically situated disk coupled with respect to the axis about which the door knob rotates and further adapted to rotate coincidentally with the door knob, the disk having a plurality of notches formed on a periphery thereof, the second locking mechanism further including a pivot member situated adjacent the open end of the channel and further adjacent the disk and adapted to pivot about a horizontal axis, the pivot member having a first end having at least one notch situated thereon and a second bevelled end, whereby the pivot member has a first orientation with the at least one notch of the first end thereof residing distant from the disk upon the locking rod being in the retracted orientation thereof thus allowing the door knob to rotate and a second orientation with the at least one notch of the first end thereof engaging the disk upon the locking rod being in the extended orientation thereof thus precluding the door knob from being rotated;

a receiver situated adjacent the motor between the front face and the rear face of the door, the receiver electrically connected to the motor and adapted to transmit an unlock signal thereto upon the receipt of an unlock transmission signal via free space and further adapted to transmit a lock signal thereto upon the receipt of a lock transmission signal via free space; and

a transmitter with a compact rectangular configuration having a top face, a bottom face, and a periphery formed therebetween, the transmitter including a battery for powering purposes, an unlock button positioned on the top face thereof for deploying an unlock transmission signal via free space upon the depression thereof, a lock button positioned on the top face thereof for deploying a lock transmission signal via free space upon the depression thereof, and a light emitting diode positioned on the top face thereof adapted to be actuated upon the battery strength falling below a predetermined level.

2. A motor driven locking mechanism comprising:

a door hingably coupled to a door frame at a first side edge thereof, the door having a horizontally orientated channel with a first open end situated on a second side edge of the door opposite the first side edge and a second closed end and a door knob rotatably coupled to the door about an axis which extends above and perpendicular to the channel;

a first locking mechanism including a locking rod for slidably inserting within the channel, a strip gear longitudinally situated on a top edge of the locking rod, and a motor located adjacent the closed end of the channel having a rotor extending therefrom with a bevel gear coupled thereto, the bevel gear in threaded engagement with the strip gear for situating the locking rod in an extended orientation with the locking rod engaged with the door frame upon the receipt of a lock signal and a retracted orientation with the locking rod residing only within the channel upon the receipt of an unlock signal;

actuation means adapted to selectively transmit an unlock signal to the motor and further selectively transmit a lock signal to the motor; and

a second locking mechanism having a vertically situated disk coupled with respect to the axis about which the door knob rotates and further adapted to rotate coincidentally with the door knob, the disk having at least one notch formed on a periphery thereof, the second locking mechanism further including a pivot member situated adjacent the open end of the channel and further adjacent the disk and adapted to pivot about a horizontal axis, the pivot member having a first end having at least one notch situated thereon and a second bevelled end, whereby the pivot member has a first orientation with the at least one notch of the first end thereof residing distant from the disk upon the locking rod being in the retracted orientation thereof thus allowing the door knob to rotate and a second orientation with the at least one notch of the first end thereof engaging the disk upon the locking rod being in the extended orientation thereof thus precluding the door knob from being rotated.

3. A motor driven locking mechanism as set forth in claim 2 wherein the channel further includes a pair of guides and each with a generally U-shaped configuration each longitudinally positioned along opposite side edges of the channel and the locking rod has a pair of elongated protrusions situated on opposite side edges thereof for slidably inserting within the guides of the channel.

4. A motor driven locking mechanism as set forth in claim 2 wherein the actuation means includes a receiver electrically connected to the motor and adapted to transmit an unlock signal thereto upon the receipt of an unlock transmission signal via free space and further adapted to transmit a lock signal thereto upon the receipt of a lock transmission signal via free space and a transmitter including a battery for powering purposes, an unlock button positioned on a top face thereof for deploying an unlock transmission signal via free space upon the depression thereof, and a lock button positioned on the top face thereof for deploying a lock transmission signal via free space upon the depression thereof.

5. A motor driven locking mechanism as set forth in claim 4 wherein the transmitter has a light emitting diode positioned on the top face thereof adapted to be actuated upon the battery strength falling below a predetermined level.
