21 Deadbolt lock US13998319 2013-10-21 US20140110954A1 2014-04-24 John Nichol
A lock consists of an elongated track which is attached to the panel of a door. A slider runs in the track from a retracted position in which the slider is spaced apart from the knob which operates the deadbolt to an engaged position in which the slider is in contact with the knob and prevents it from turning. The slider can be locked in that position by means of a locking pin. The pin may also be used to immobilizes the slider in the retracted position.

An improved security system to prevent unwanted entrance through a hinged barrier, such as, but not limited to a door, is provided and comprises a member associated with the barrier, whether internal or eternal to the barrier, and adapted to extend from a first length to a second length. An actuation mechanism is coupled to the member and is adapted to extend the member from the first length to the second length and to contract the member from the second length to the first length. A receptacle is provided adjacent the barrier for receiving a portion of the member when the member is extended by the actuating mechanism. A hinge assembly is provided and is disposed substantially opposite the receptacle and adjacent the barrier and is coupled to another end of the member, such that when the member is actuated to the extended position, the member, receptacle and hinge assembly form a security system to prevent unwanted entrance through the barrier.
24 DEADBOLT LOCKING DEVICE US13539502 2012-07-02 US20130000369A1 2013-01-03 ELTON G. DAVIS
Deadbolt locking devices for preventing a deadbolt from being unlocked from the outside are provided. The deadbolt locking devices may include a connecting assembly, for engaging a door knob to provide leverage to resist turning of the handle of the deadbolt, and a housing member for engaging the handle of the deadbolt when in a locked position. The deadbolt locking devices can accommodate various configurations of door hardware without sacrificing convenience of use and without sacrificing confidence in its correct placement. Various configurations of door hardware can include the position of the deadbolt knob in relation to the door knob, the angular position of the handle of the deadbolt when it is in the locked position, whether the door is hinged on the left or right side and whether the deadbolt knob turns clockwise or counter-clockwise to lock the door.

26 Compact folding deadbolt restrictor US11498601 2006-08-04 US07418847B2 2008-09-02 Marjan Kosi
An apparatus for preventing a deadbolt lock from being opened from the outside of a door with a key. The base is constructed from resilient material, the base defining at least one aperture for receiving one of a plurality of types of finger actuator in one of a plurality of orientations, the aperture shaped to prevent a finger actuator inserted therein from rotating relative to the base. A U-shaped plate is coupled to the base and is moveable between an extended position wherein the U-shaped plate is engageable with a member extending outwardly from the door and a storage position wherein the U-shaped plate is adjacent to the base. When a finger actuator is in the locked position and inserted into the aperture, and when the U-shaped plate is engaged with the member extending outwardly from the door, the finger actuator is prevented from moving into the unlocked position.

28 Dead bolt lock US10699342 2003-11-03 US06993944B2 2006-02-07 Thurman B. Hicks
A dead bolt lock having a slot or slots for insertion on a dead bolt and legs for spanning the underlying door knob of a door to secure the dead bolt. In an adjustable embodiment the dead bolt lock includes a lock housing having a circular rim and downwardly-extending legs, with notches disposed around the curved top portion of the housing rim. A round opening in the center of the housing rotatably accommodates at least a middle plate, closed by front plate, and a rear plate, the middle plate provided with a middle plate profile slot for receiving a sliding retainer block. The retainer block alternately recesses in a corresponding retainer block slot adjoining the middle plate profile slot and extends into the middle plate profile slot for selective engagement with the dead bolt when the dead bolt lock is in locked configuration. The front plate and rear plate are connected to the middle plate and each have slots that correspond to the middle plate profile slot for accommodating the dead bolt. Spring-loaded adjusting and keeper mechanisms are slidably recessed in the middle plate to facilitate rotating and locking the rear plate, middle plate and front plate in concert on a dead bolt oriented in any angular locked position on a door. Fixed, vertical, horizontal, X-slot and cross-slot configurations are also alternatively provided in the lock housing for accommodating dead bolts in various angular locked configurations.
29 Door lock lever hold US11035496 2005-01-14 US20050193787A1 2005-09-08 Hollis Davis
The nature of my invention is to hold the turn lever knob for some home entrance doors in it's set position even when a key is used from the outside side of the door for the dead bolt door lock system. There are no moving parts and no construction modifications are required when the corresponding size device is used. The device interlocks with the rectangular turn lever knob controlling the locking function at the top of the device while also interlocks with the door knob and the door knob's axle at the lower end to counter resist against the use of a key from the outside to unlock the lock. The device is useful when dead bolt lock key is missing, lost or stolen. Until the lock is replaced entrance with a key must be granted by the person on the inside side of the entrance door.

A security locking assembly comprises a face plate locatable upon a dead bolt lock having a turn knob and a C-shaped component. The face plate has first and second apertures extending through it above and below the turn knob. A planar member with a circular hole is affixed to the face plate and extends within the dead bolt lock opposite from the turn knob. The C-shaped component includes a first horizontal bar, a second horizontal bar and a vertical bar. Each horizontal bar has an inboard end and an outboard end. The vertical bar includes an upper end, a lower end and a center point. The first and second horizontal bars are pivotally coupled in a generally perpendicular orientation to the upper and lower ends of the vertical bar, respectively. The vertical bar is pivotally coupled to the planar member by a hinge pin coupled through the aligned central hole of the vertical bar and circular hole of the planar member. The outboard extent of the first and second horizontal bars extend through the apertures of the face plate adjacent to the turn knob.

34 Accessory for doors having supplemental locks US268488 1988-11-08 US4885921A 1989-12-12 Vera Sharav
A cover for the various locks that are often placed a few inches above the door-knob is provided. The cover is an elongated plate spaced from the door and having sidewalls extending almost to the door. The cover has a downwardly extending portion that surrounds the shaft of the door-knob and has a hole through the shaft of the door-knob and has a hole through which the door-knob passes when the cover is rotated on its hinges to an open position. A jamming device has an indent for receiving the key or handle of one of the locks on the door. The jamming device bears against the shaft of the door-knob and prevents the key or handle of the lock from turning. Hence, the lock remains locked when the jamming device is used.
