A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.

A lockable pipe cover includes an inner cap and an outer cover which are selectively coupled together for axial rotation. When the cap is locked, the inner cap and the outer cover are free to rotate independently from one another thus rotation of the outer cover will not remove the cap from the pipe. In the unlocked position, the inner cap and the outer cover are coupled for rotation and thus rotation of the outer cover results in rotation of the inner cap.

A security cover for an automatic gate arm protects against disengagement and removal of the gate arm for the purpose of unauthorized entry through the gate. The security cover comprises four walls and a top plate joined to form a housing that encloses a rotating turret and a portion of a drive arm used to actuate the gate. The security cover mounts over the turret using a vertical rod that extends from above the housing to a location within the drive mechanism of the gate arm motor, and a lock that secures the housing and prevents unauthorized tampering with the drive arm.

There is disclosed an improved lock assembly particularly suited for bulk vending machines, the lock assembly formed by an upper portion including a lock barrel having a lock collar extending downwardly therefrom, the lock collar having a tubular configuration with a hollow interior. A lock pin is secured within the hollow confines of the lock collar. The lock assembly further includes a lock post which is intended to be screwthreadedly mounted to a mounting bar, and the lock post including a first diametric channel cut into the upper portion thereof along a diametric centrally positioned plane, and continues into a curvilinear channel, ending at a pair of opposed stop points, the plane formed by the stop points being exactly 90° perpendicular to the plane formed by the diametric lock channel.

To endow such a device, of the type with a bolt (1) actuated by a key (2), with a high level of tamper-proofing and security without compromising its simplicity and reliability, the device includes two bolt-guiding members (3, 4) carried by one of the two elements, and the bolt includes a key-inserting aperture (114), two guiding ramps (112, 113) cooperating with the guiding members, and a third guiding ramp (115) cooperating with the key (2) when the latter is inserted into the aperture (114), in order to selectively actuate the bolt (1) from a locking position to an unlocking position, and vice versa, by rotation of the key. Use: devices for closing roadway or footway manholes, or underground technical chambers.

A portable lock box includes a box-shaped base member having an open front and top and a box-shaped front closure member having an open back and top. The base and front closure members include complementary horizontal support members and the front closure member is dimensioned to be slidably received through the open front of the base member to form a base assembly that may be filled with ballast. Respective support members define apertures through which elongate fasteners may be extended when aligned so as to couple the front closure member to the base member. A top panel is configured for slidable engagement with the base member so as to cover the open top. The top panel and base member include corresponding bores through which a rod may be extended and locked. Selected items may be stowed for safekeeping in a compartment mounted to an underside of the top panel.

A portable housing device for protectively enclosing the steering wheel and driver's side airbag of an automotive vehicle to prevent theft. The device includes a plurality of sections sharing a common axis member. One section is fixedly connected to the axis member, which serves as a pivot point around which each remaining section may be rotated. An integral keyless locking mechanism is included to automatically secure the device once it has been installed on a steering wheel by fixedly connecting each rotatable section to the axis member. The size of the device is substantially reduced for storage purposes by selectively varying the dimensions of each section and by locating the axis member so that each rotatable section is pivotable in a concentric arc around it to a single nested position including the fixedly connected section. Certain embodiments include an interference bar member, an electronic alarm system, or both, to enhance the anti-theft capability of the device.

A condom case is provided that houses one or more condoms within an enclosure having two distinct and interdependent locking mechanisms. Two separate keys must be employed simultaneously to disengage the locking mechanisms and open the condom case. The condom case pragmatically protects the condom while symbolically promoting the concepts of mutual consent, fidelity, dignity, commitment and intimacy. The keys may be worn around the necks of each individual as an overt talisman of their exclusive relationship.

A locking device for use with a video cassette tape to prevent unauthorized usage in view of its content. The device incorporates a member that is expandable into certain recesses of the cassette when placed into a locking mode and, is not expanded when the cassette is in a non-locking mode. A specialized key is utilized with the device to prevent its duplication.

A locking assembly used to deny access to a nut or to a bolt head to prevent theft of an article that is bolted to a body such as a vehicle. The locking assembly includes a retainer through which the bolt passes and that partially surrounds the nut or bolt head that secures the retainer to the body. The retainer includes a groove that extends circumferentially around it. The locking assembly also includes a housing that fits over the retainer and that is selectively engaged to the retainer by a ball bearing that is pushed into the groove on the retainer when a key turns the shaft of a lock which turns a cam that pushes the ball bearing into the groove. The locking assembly has an exceptionally low profile, made possible by positioning the lock perpendicular to the axis of the bolt. Further strength is imparted to the locking assembly by the fact that the retainer is almost as deep in the axial direction as the housing, and the strength of the retainer reinforces the housing.
