ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to telephonic communication apparatus and, more particularly, to private, single-line lockout systems.
BACKGROUND OF THE INVENTION
Teenaged children often linger for hours on the telephone chatting with out-of-town friends or surfing the Internet running up monthly bills in the hundreds of dollars. While these bills often surprise their guardians who are charged with paying them, there has never been a good way to directly reduce billed sums other than to physically remove telephones from rooms in a home where children have access—often a less that desirable problem solution since the guardians' telephone access is equally restricted. A need, therefore, exists for a lockout apparatus that can be used by an adult to control the connection of a number of telephones positioned throughout his home to a telephone network.
SUMMARY OF THE INVENTION
In light of the problems associated with the telephone apparatus commonly installed in homes, it is a principal object of the invention to provide a lockout apparatus that may be easily employed by a user to selectively control communications on a single line telephone system in his home. Briefly, such an apparatus features a principal telephone connected to a remote telephone network. A switch is positioned adjacent the principal telephone that is connected in parallel with the principal telephone and connected to the remote telephone network. A plurality of secondary telephones are connected to the switch such that, when the switch is manually closed, telephonic communications signals may pass between the principal and secondary telephones and the remote telephone network.
It is an object of the invention to provide improved elements and arrangements thereof in a lockout apparatus for the purposes described which is inexpensive to manufacture, easy to install, and fully dependable in use.
The foregoing and other objects, features and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawing.
