Abstract: A new keyless door knob security device with stabilizer arm for preventing access to a keyhole of a door knob to prevent unauthorized access. The inventive device includes a central shaft that has first and second ends and a longitudinal axis extending between the ends. A claw ring has a plurality of claws extending outwardly from it and an aperture through it. The central shaft extends through the aperture of the claw ring. The claws are adapted for grasping the door knob. A cover is slidably positionable along the central shaft such that sliding the cover in a first direction presses the claws towards each other such that the claws grasp the door knob. Sliding the cover in a second direction permits the claws to move apart from each other. A locking mechanism permits selective locking of the cover in a locked orientation and an unlocked orientation.

Abstract: Disclosed is a security device for securement to a door in association with a latch mechanism having a face plate and knob to selectively prevent unauthorized turning of the latch mechanism and knob. The device includes a plate for securement to the door in association with the face plate of the latch mechanism.

Abstract: The instant invention is a locking mechanism for transmissions having a floor mounted selector switch. The invention utilizes a base member which is attached to a support post of the transmission selector lever. The base member includes provisions for holding loose coins and miscellaneous items. When the vehicle is left unattended, the locking mechanism utilizes a spherical cap which locks to the base member. With automatic transmissions the handle is locked together so as to conceal the handle and prevent access to the actuator button. When used in combination with a manual transmission, the cap engages the base of the transmission housing to prevent depression or movement of the selector handle. In this manner, the vehicle cannot be moved as the transmission is disabled. The spherical shaped cap inhibits cutting, tensile steel bands used on matching caps prevent the mechanism from being pried apart when locked.

Abstract: A locking device for selectively preventing access to the valve handles of a domestic water tap. The locking device is adapted to prevent a child from playing with the hot water tap handle and potentially getting burned by the hot water emanating from the hot water tap. The locking device has a pair of handle enclosing components which are adapted to enclose the tap handles and prevent access to the latter. Each handle enclosing component has a substantially concave-shaped wall defining a substantially hollow body. Each substantially concave-shaped wall has a corresponding peripheral edge defining a lateral aperture. The handle enclosing components are linked together by a pair of connecting rods extending from the respective peripheral edges of the handle enclosing component. Both connecting rods are attached to a locking block positioned intermediate the handle enclosing components.

Abstract: A locking device for air brake valves on vehicles is provided which comprises releasable elements for engaging an air brake valve control knob at the dashboard of the vehicle to prevent the control knob from being pushed inwardly to release the air brakes when the locking device is properly secured in place between the head of the control knob and the dashboard of the vehicle.

That yoke may reside within a hinged, flanged, and contoured apparatus, comprising the remainder of the protection enclosure, that may be repeatedly and effortlessly installed and removed.

Abstract: A removable protector for a locking mechanism, such as a door knob or window lock is disclosed. The protector comprises a magnetically attractive member, such as a circular base plate, surrounding the locking mechanism and a housing magnetically attached thereover to discourage access. The housing is dome shaped in configuration and has an aperture to receive a lever whereby the housing may be removed from the circular plate to allow full access to the lock.

Abstract: The invention provides an accessory locking mount for removably attaching a CB radio or other electrical accessory to a support member. The mount includes a first, adjustable bracket to which the accessory is rigidly affixed and which tightly embraces the accessory to carry the accessory. The mount also includes a second, adjustable bracket rigidly affixed to a support member and adapted to slidably receive the first bracket. The various elements are assembled by carriage bolts having rounded heads projecting outwardly of the mount. The bolts cannot be loosened or removed from outside the mount so that unauthorized adjustment or removal of the mount is not possible when the first and second brackets are engaged. An internally disposed, ramp-like, plug-in electrical connector is employed to permit the accessory to be carried wherever desired upon disengagement of the first and second brackets.

Abstract: A security locking device for dead-bolt door locks which is distinguished by a shroud that encompasses and grips the dead-bolt actuator at the inside of the door, and is rotatably mounted in a base secured to the inner face of the door, with a handle portion on the shroud exposed to enable the shroud -- and hence the dead-bolt actuator -- to be manually turned. A spring biased security bolt slidably mounted in the base engages a cylindrical side surface of the shroud and snaps into a keeper recess in that surface when the shroud is turned to the position at which the dead-bolt is in its projected door-locking position. A manually rotatable cylinder with an eccentric lug at its inner end to engage one or the other of a pair of opposing shoulders on the security bolt is mounted in the base and operable from inside the door to enable retraction of the security bolt and to selectively hold the security bolt in either its projected operative position or its retracted inoperative position.

Abstract: A locking device for an outboard motor having a C-shaped mounting bracket fitting over the back transom of a boat and containing a mounting screw with a handle at one end for tightening a foot at the other end against the transom, said locking device having a first member with two angular arms, one of which is secured against the transom by the foot of the mounting screw and the other arm locked to a second member having a handle restraining portion located adjacent the handle to prevent rotation of the handle.

Abstract: A lever arm lock for a conventional quick-release hub assembly includes a cover mountable to a first skewer rod end nut supporting a quick-release lever arm. The cover is secured to the end nut with a locking mechanism (combination, magnetic, key, etc.) and maintains the lever arm in a locked position making it impossible to remove the hub. A second skewer rod end nut opposite the first end nut is formed with a substantially smooth outer surface that is continuously inclined with respect to the axle. This surface configuration prevents removal of the locked hub assembly by turning the second end nut with a pliers or other tool. The lever arm lock also prevents the hub from being jarred loose on impact with curbs, rocks, etc. The end nut assemblies have extensions which abut the frame thereby preventing loosening thereof for unauthorized removal.
