  • Publication number: 20120073338
    Abstract: A deadbolt that automatically locks based on the location of a key fob that is in a user's possession. The deadbolt automatically unlocks whenever the key fob is within a designated distance from the deadbolt and automatically locks when the key fob is past a designated distance from the deadbolt. Additionally, a key can be used to manually unlock the deadbolt at anytime and the deadbolt can be switched to manual mode so it functions like a traditional deadbolt.

  • Publication number: 20100313612
    Abstract: A low-cost switch sensor remote dead bolt status indicator includes a switch sensor which starts a transmitter at a door lock location upon sensing of a dead bolt entering into a locked position. The transmitter is provided with a self shut-off feature operating after a fixed duration of minutes length has elapsed. The indicator also includes a receiver in a hand held unit, such as a key fob capable of receiving signals from the transmitter after the user presses an inquiry key on its surface. The hand held receiver having two indicators for alternately displaying the lock's dead bolt status as being locked or unlocked. In an alternate embodiment, the switch sensor is provided as an integral part bonded to the conventional manufactured metal strike plate dead bolt frame that is typically attached to the door jamb.

  • Publication number: 20100307060
    Abstract: The present invention relates to a vault door mechanism that assists a user in opening or closing the door. A hold-open arm and hinge plate pivotally interconnect the door to a surrounding frame and are fixed in place by an associated locking mechanism. The locking mechanism stops the door in the partially opened position prior to being fully opened or closed, thereby assisting the user in handling the door. The details of the present invention, and the manner in which they interrelate, will be described in greater detail hereinafter.

  • Publication number: 20100107707
    Abstract: A dead bolt latch (10) readily adjustable between forward and rear backset positions. A bolt casing (56) connects to a faceplate (48) installed on an outer face of a door (D). A bolt (15) fitting within the casing extends and retracts to latch or unlatch the door. A latch operator (12) and the bolt casing each have slots (64, 78) of a length corresponding to the distance between the backset positions, and a spring (72) seats between the bolt and latch operator. When the latch is being installed and needs to be adjusted between backset positions, the installer blocks movement of the bolt and then, by turning the latch operator, moves the relative position of the latch operator and bolt between backset positions using the force of the spring. This facilitates latch adjustment even by relatively unskilled installers.

  • Publication number: 20080121002
    Abstract: A deadbolt lock device includes a housing having an inner case covered by an outer case, and an adaptor connected to the inner case. The inner case has an annular flange projecting inwardly from an open end thereof in a direction toward the adaptor, and an annular rib projecting transversely from the annular flange. The annular rib defines a through hole receiving a key-operated lock unit. The annular rib has an annular edge surrounding the lock unit and extends inclinedly from the juncture of the annular rib and the annular flange to the annular edge along directions inclining toward the open end. The annular rib is inclined with respect to a plane intersecting perpendicularly an axis of the lock case. The inclined annular rib provides an increased resistance to destructive forces.

  • Patent number: 6688063
    Abstract: A storm door construction includes an internal rectangular frame providing a pane opening, the frame including left and right vertical members, a head panel and a base panel. One of the left and right vertical members comprises upper and lower vertical stile pieces and a mortise box located between the upper and lower vertical stile pieces. The mortise box has an opening sized to receive a mortise lock therein. Inside and outside skin panels shaped to cover both sides of said rectangular frame and having rectangular openings substantially in registry with said rectangular pane opening are laminated onto the frame. Both vertical members can include mortise boxes for alternate left or right side mounting of the door in an external doorframe. Each mortise box can comprise upper and lower tongues, and each upper and lower vertical stile pieces can comprise a groove that is sized and shaped to engage a respective tongue of the mortise box.

  • Patent number: 6449995
    Abstract: An automatic locking mechanism engages a deadbolt lock after a prescribed time interval following entry. The mechanism employs a spring-operated mechanical timer, which may be actuated when a key or thumbturn is turned to unlock the door, and avoids the need for a key to set the deadbolt. The mechanism includes a gear system for retracting and inserting the deadbolt and a mechanical restraint to withhold the deadbolt until the timer has expired. In a suggested embodiment, a cam attached to one of the timer gears removes the restraint when the timer runs down. This deploys the deadbolt, automatically locking the door. In another embodiment, automatic locking may optionally be disabled by inhibiting coupling between the gear system and the timer spring.

  • Patent number: 4697842
    Abstract: A front cover device for small-sized vehicles having a steering support which supports a front wheel steering mechanism. The front cover device comprises a leg shield member which surrounds the steering support portion and which covers the front and lateral sides of the steering support, and a goods accommodating space which is formed within the leg shield member and around substantially the entire circumference of the steering support. The front cover device is relatively solid and light with substantial design freedom for providing a favorable appearance while providing a relatively large goods accommodating space. The leg shield member includes a lid member which is pivotally secured at the lower end thereof to a front portion of the leg shield member through at least one hinge mechanism. Also, the vehicle includes at least one bumper comprising an elastic member which is mounted so as to cover the hinge mechanism, whereby the bumper comprises a forwardmost projection of the front cover device.
