Abstract
A device allowing engagement of a conventional keyed deadbolt lock tumbler assembly without use of a key is provided. The device is assembled around the tumbler assembly and is fitted into a standard:door lock cut-out. The device includes a rotatable ring extending substantially around the periphery of the device. At rest the rotatable ring is biased in an original starting position. Upon overcoming the bias, the rotatable ring is moved to a second engaging position. Upon release of the rotatable ring the ring is biased back to the original position, while at the same time the deadbolt remains engaged. The biasing back of the device prevents the lock from binding or jamming.
Claims25
A keyless deadbolt lock engaging apparatus for use with a conventional deadbolt assembly, the apparatus comprising:
- an actuator means to engage the deadbolt assembly;
- a rotatable ring assembled with and capable of rotating against one or bearing surfaces of a body, said rotatable ring capable of rotating from a first position in which the actuator means is in a deadbolt disengaged position to a second position in which the actuator means is in a deadbolt engaged position;
- and
- a biasing means connected with said rotatable ring to return the rotatable ring from the second position to the first position while the actuator means remains in the deadbolt engaged position;
- said actuator means, rotatable ring, and body attached with said conventional deadbolt assembly.
A keyless deadbolt lock engaging apparatus for use with a conventional deadbolt lock assembly, the lock assembly having an axial actuator, the apparatus comprising:
- a body having a center aperture through which the lock assembly is located, the lock assembly being secured to the body;
- a locator ring to secure the apparatus to a door fitted with the conventional deadbolt lock assembly;
- a radial actuator to engage the deadbolt assembly, the radial actuator including an arm extension and a center aperture through which the deadbolt lock assembly axial actuator is located;
- a rotatable ring capable of rotating from a first position in which the actuator means is in a deadbolt disengaged position to a second position in which the actuator means is in a deadbolt engaged position;
- and
- a biasing means connected with said rotatable ring to return the rotatable ring from the second position to the first position while the radial actuator remains in the deadbolt engaged position.
A keyless deadbolt lock engaging apparatus for use in combination with a conventional deadbolt lock tumbler assembly having an axial actuator, the apparatus comprising;
- a locator ring to secure the apparatus to a door to be fitted with the conventional deadbolt lock assembly;
- a body to substantially house the lock assembly;
- a rotatable ring, the rotatable ring including a radial finger;
- a return spring mechanism connected with said radial finger of said rotatable ring;
- and
- a radial actuator having a.projecting arm, the arm being located adjacent to and moveable by the rotatable ring radial finger, the radial actuator further including a center aperture through which the lock tumbler axial actuator is located;
- whereby upon turning the rotatable ring from a first position to a second position the radial finger pushes the radial actuator from a deadbolt disengaged position to a deadbolt engaged position, and further whereby upon release of the rotatable ring the return spring mechanism causes the rotatable ring to rotate back to the first position while allowing the radial actuator to remain in the deadbolt engaged position.
A keyless deadbolt lock engaging apparatus for use in combination with a conventional deadbolt lock tumbler assembly having an axial actuator, the apparatus comprising:
- a locator ring to secure the apparatus to a door fitted with the conventional deadbolt lock assembly, the ring including a projection having an outer shoulder projection of decreased diameter;
- a body including a channel portion, the channel portion including shoulder grooves, the body further including step projections extending into the center of the body, the step projections preventing the body from rotating about the tumbler assembly, the portion of the body adjacent the locator ring being a shoulder of a decreased diameter, the body shoulder and locator ring shoulder forming a radial channel;
- a rotatable ring located within and being rotatable about the radial channel formed by the body and locator ring, the rotatable ring including a radial finger extending inward, the radial finger having a notch;
- a spring ring including a spring stop, a grooved portion and an end stop, the spring ring being located within the body channel, the grooved portion being located within the rotatable ring finger notch;
- a return helical coiled compression return spring coiled about the spring ring, the spring being located between the spring ring spring stop and the body channel shoulder;
- and
- a radial actuator having a projecting arm, the arm being located adjacent to and moveable by the rotatable ring finger, the radial actuator further including a center aperture through which the tumbler actuator is located;
- whereby upon turning the rotatable ring from an original position the radial finger pushes the radial actuator from a deadbolt disengaged position to a deadbolt engaged position, the radial finger further pulling the spring ring by the grooved portion thereby causing the return spring to be compressed between the body shoulder groove and the spring ring spring stop, and further whereby release of the rotatable ring the return spring causes the rotatable ring to rotate back to the original position while allowing the radial actuator to remain in the deadbolt engaged position.
