A security device for a handle of a door or a window for protecting against unauthorized actuation has a cover enclosing in a mounted position the handle. A lock is provided that secures the cover on the handle in the mounted position and releases the cover from the handle for removing the cover from the handle. The cover has at least two locking elements. Counter members are disposed on the handle, a handle fixture, a door, or a window, and are matched and interact with the at least two locking elements. One of the locking elements is a locking bar of the lock.

A lock structure for an electrical device is provided. The lock structure includes a rotatable fastener, a lock body, an operation device, and a housing. The lock body is disposed at least partially in the housing, connected with the operation device, and couples with a driving portion. When the lock body is in an unlocked state, the lock body allows the driving portion to move the rotatable fastener. Simultaneously, the operation device can move the driving portion to change the orientation of the rotatable fastener, resulting in the connection/detachment of the lock structure and the electronic device. When the lock body is in a locked state, movement of the driving portion is restricted and the operation device cannot directly or indirectly rotate the rotatable fastener, resulting in the secure connection of the lock structure and the electronic device.

A lock structure for an electrical device is provided. The lock structure includes a rotatable fastener, a lock body, an operation device, and a housing. The lock body is disposed at least partially in the housing, connected with the operation device, and includes or couples with a driving portion. When the lock body is operated to achieve an unlocked state, the lock body allows the driving portion to move the rotatable fastener. At the same time, the operation device achieves an operable status in which the operation device can move driving portion to change the orientation of the rotatable fastener, resulting in the connection/detachment of the lock structure and the electronic device. When the lock body is in a locked state, the movement of the driving portion is restricted and the operation device is not operable to directly or indirectly rotate the rotatable fastener, resulting in the secure connection of the lock structure and the electronic device.

A keyway plug that provides a means for preventing the correct key from opening a tumbler lock, including a plug and an extractor. The plug fits into the keyway to block complete insertion of a key. An arm extends from the tip of the plug across the tumblers, but is short enough so that the outermost tumbler drops to hide the plug. The extractor includes a narrow finger, the end of which pushes the innermost part of the plug upwardly, while the tumblers push the outermost part of the plug downwardly. A chamfer at the outer end of the plug arm pushes the outermost tumbler up out of the way so the plug can be removed. The upper edge of the finger includes a hook that mates with a matching notch in the lower edge of the plug arm. As the extractor is removed, the hooks and notch interlock, pulling the plug from the keyway.

A lockable doorknob enclosure for use on doorknobs of the type having a knob attached to a shaft having a longitudinal axis. The lockable doorknob enclosure comprises: a containment structure having a sealable cavity for enclosing the doorknob and a portion of the shaft; an adjustable spacing mechanism; and a locking mechanism. The containment structure includes first and second pivoting structures which are preferably connected by a hinge. The first and second pivoting structures form a containment cavity of a size sufficient to receive therein the doorknob and a portion of the shaft when the pivoting structures are pivoted into a first, or closed, position. The containment structure has an aperture therethrough of dimensions sufficient to allow the shaft to be installed through the aperture when the first and second pivoting structures are pivoted into a second, or open, position. The adjustable spacing mechanism is located within the containment cavity and is positionable between the door knob and the aperture in a manner such that movement of the doorknob is restricted in a direction along the longitudinal axis of the shaft. An exterior portion of at least one of the first and second pivoting structures preferably includes a padded surface extending therefrom.

An apparatus for secure positioning over and around a steering wheel and steering column to prevent theft. The apparatus comprises a plate positionable over the top of a central part of a steering wheel having a steering column with laterally extending rods for turn signals and the like. The plate has a short post extending downwardly from one edge thereof with an upper end pivotally secured about an axis with respect to the plate and with the lower end having an inwardly projecting leg. The plate also has a long post which extends downwardly from a second edge of the plate diametrically opposite from the first edge with an upper end pivotally secured about an axis with respect to the plate about an axis parallel with the first axis and with a lower end having an outwardly projecting leg. The apparatus further includes a first housing half and a second housing half positionable around the steering column beneath the steering wheel. The first and second housing halves having inner walls and outer walls and planar linear walls therebetween with parallel upper and lower faces. The upper faces have a recess for the removable receipt of the outwardly projecting leg. The upper face of the first housing half is closer to the plate than the upper face of the second housing half. The apparatus further includes means to rotatably couple the first and second housing halves.

The present doorlock closure secures existing doors having conventional doorknobs against entry by enveloping the doorknob with opposed cavity compartments of knob confining segments. Upper and lower housing segments are hinged together such that they may mount elements which form a cam-lever, segment interlocking assembly. The assembly includes a spring-loaded latch and lockable latch lever in the upper segment and a corresponding cam latch release in the lower segment. The housing segments themselves are hinged together for facile clamping upon the doorknob of a door, securing it against entry by persons having a passkey to the doorknob which retains a turnkey lock therein.

The present invention entails a doorknob security device for preventing access to the outer surface of the doorknob and particularly to a keyhole or other locking and unlocking mechanisms formed about the surface of the knob. In particular, the security device of the present invention comprises an outer main housing and a rotatable inner closure panel. The inner closure panel is rotatable from a closed to an open position. In the open position the security device easily accepts a doorknob. In the closed position the security device encompasses and closes the doorknob preventing access to the same.

A barrel lock assembly for use in securing a lock housing over the latch or access point of a securable enclosure, such as a utility meter box, is disclosed, having a bar member with a stop on the distal end for engaging a surface on the lock housing or on the enclosure to be secured. A second bar member is disposed parallel to the first and has a head portion which receives the proximal end of the first bar member. The head and the first bar member have axially aligned apertures for receiving a suitable padlock and holding the assembly together.
