Abstract: A device for limiting unauthorized access to a telephone hand set. The device comprises a cabinet for receiving and holding a telephone hand set. The cabinet has an enclosed bottom, enclosed sides and an open top. A removable cover is received into the upper portion of the cabinet and has an open and a closed position. When in its closed position the cover seals the open top of the cabinet to enclose and limit access to the key pad of the telephone hand set while providing unlimited access to the receiver. When in its open position the cover provides unobstructed access to the telephone hand set. The cover allows for the activation of pre-determined keys on the key pad of the telephone hand set when the cover is in its closed position. A lock secures the cover in its closed position.

Abstract: A lockout system for preventing children from accessing parentally-restricted and undesirable electronic information through an interface device of a computer comprises a signal cable connected at one end with a signal port and at the other end with an interface device of a computer through an opening in a case of the computer, so electronic information may pass back and forth between the interface device and port and a locking device coupled in-line with the signal cable. The locking device, when actuated, disables the signal cable to prevent electronic information from passing between the interface device and port so that children cannot gain access to information prohibited by parents. A protective collar is configured for engaging the computer body proximate the opening in the case and maintaining the other end of the signal cable in operable connection with the interface device to hinder a bypass of the lockout system.

Abstract: A lockout telephone comprising a keyswitch for controlling the operation of the telephone's push button keypad and speed dial buttons. The telephone can have a keyswitch with either ON and OFF positions or ON, SPEED DIAL ONLY, and OFF positions. When the keyswitch is in the ON position, the telephone is fully operational. When the keyswitch is in the SPEED DIAL ONLY position, only the speed dial buttons are operational. When the keyswitch without a SPEED DIAL ONLY position is in the OFF position, only the the keypad is inoperative. When the keyswitch with ON, SPEED DIAL ONLY, and OFF positions is in the OFF position, both the keypad and speed dial buttons are inoperative. The lockout telephone can also have an emergency dial button which is always operational, regardless of the keyswitch position.

Abstract: A secure timed telephone switch apparatus for a telephone or telecommunication device wired to a telephone system circuit by at least one pair of wires, one wire being supplied with voltage. The apparatus includes a clock that may be set to provide a signal at predetermined times during a 24 hour period and during a 7 day period. A central processing unit programs and stores information for the predetermined times of the clock. A switch mechanism connected to the voltage supplied wire is responsive to the signal to switch between connection and disconnection of the telephone system circuit, the switch operably engaged with the clock and the central processing unit so that the telephone or telecommunication device will be disconnected and connected to the telephone system in response to the signal.

Abstract: A security bracket for a portable telephone provides locking security for at least the transceiver, battery, and carrying bag of such a telephone installed in a vehicle, while allowing ready access to the telephone handset. An open top container is dimensioned to receive the transceiver, battery and carrying bag, which are locked in place by a hinged, generally U shaped lock bar. The telephone hand set is placed atop and within the U of the lock bar where it also engages the transceiver for normal operation and provides access for ready use at all times. Thus, the security bracket provides deterrence against theft, as the only component readily removable is the telephone hand set, which is of little value without the remaining components which are secured within the container of the security bracket. A base supports the container, the base being securely mounted on the floor of the vehicle. The container may be angularly adjusted with respect to the base for ease of access to the telephone by the user.

Abstract: A building entrance protector unit (20) includes plurality of electrical connectors (86) providing electrical connections between wire pairs (104, 105) leading from telephone stations of subscribers in the building and wire pairs (57,58) from the local telephone networks serving the unit, these connections being interruptible by the subscribers for the purpose of plugging in their telephone sets to the network to test these sets. The connections are tamperproofed by a hasp mechanism (87) providing hasp leaves (130) respective to these connectors and each lockable in a first position impeding access to the corresponding connection by attachment of a padlock (170) to a hasp staple (150) projecting through that leaf. That locking may be overridden by a telephone network technician by a releasing from a held position of a common mounting (111) for all the hasp staples.

Abstract: A quick release latching mechanism is provided for restraining a handset of a telephone set. Easily adaptable to fit most existing telephone sets with minimal modifications, the latching mechanism is also easily manufactured, yet satisfies existing safety requirements by being able to restrain the handset during harsh operating conditions. The handset is securely restrained in the handset cradle of a telephone set base by a floating toggle type latch which is balanced around its pivot point and is the only moving part in the quick release latching mechanism. A coil spring is provided to return this latch to its closed position. Any shock forces encountered by the latch are not absorbed or counterbalanced by the spring force since these shock forces are applied in a direction normal to the force exerted by the spring. The spring force, therefore, does not secure the latch in the closed position. Rathr it simply serves to return the latch to this position when the latch is permitted to move freely.
