Abstract

Abstract In a preferred embodiment of the invention, for securing the concealment against unauthorized use of the dial push-buttons of a push-button telephone, a lock-on mechanism having metal strips that either circumscribe the telephone structure at the position of location of the push-buttons or which - in the absence of circumscribing the entire telephone body - clamp onto edges of the telephone structure, preferably there being included a hinge structure such that the locking abutting ends are at least one pivotal upwardly away from the other to make accessible the pushbuttons, and the button-covering strip of metal having preferably a plurality of downwardly extending parallel flanges running longitudinally along the strip toward the hinge structure such that when in the locked state the substantially perpendicularly extending flanges - relative to the underside face of the metal strip cover - fit between the consecutive rows of push-buttons preventing the possibility of the locked strip from being slipped laterally from over the push-buttons.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 231 words
A button-telephone lock-guard device comprising in combination: at least first and second structure means, one including a first portion of a locking means and the other including a second portion of a locking means, the first and second locking portions comprising in combination a locking means for locking releasably one to the other, at least one of the first and second structure means including at least one downwardly extending partition element of a predetermined size and shape received between adjacent buttons of a push-button telephone when the locking means is in a locked state, each of the first and second structure means including securing means fastened securely to and at least partially circumscribingly of a button-containing portion of the push-button telephone when the locking means is in a locked state such that when each of the first and second structure means are fastened to the push-button telephone having push buttons, and the locking means in a locked state, the at least one downwardly extending partition element extending longitudinally along with of the first and second structure means, providing thereby against lateral shifting of the first and second structure means and also providing thereby a deterrent against access to the buttons, each partition element being an elongated thin flange extending downwardly from an upper portion of at least one of the first and second structUre means at substantially a right angle thereto.
Claim 2
Dependent Claim 231 words
A button-telephone lock-guard device comprising in combination: at least first and second structure means, one including a first portion of a locking means and the other including a second portion of a locking means, the first and second locking portions comprising in combination a locking means for locking releasably one to the other, at least one of the first and second structure means including at least one downwardly extending partition element of a predetermined size and shape received between adjacent buttons of a push-button telephone when the locking means is in a locked state, each of the first and second structure means including securing means fastened securely to and at least partially circumscribingly of a button-containing portion of the push-button telephone when the locking means is in a locked state such that when each of the first and second structure means are fastened to the push-button telephone having push buttons, and the locking means in a locked state, the at least one downwardly extending partition element extending longitudinally along with of the first and second structure means, providing thereby against lateral shifting of the first and second structure means and also providing thereby a deterrent against access to the buttons, each partition element being an elongated thin flange extending downwardly from an upper portion of at least one of the first and second structUre means at substantially a right angle thereto.
Claim 3
Dependent Claim 253 words
A button-telephone lock-guard device comprising in combination: at least first and second structure means, one including a first portion of a locking means at a first end thereof and a hinge element at an opposite end thereof, and the other including a second portion of a locking means at a first end thereof and a second hinge element at an opposite end thereof, a hinge means comprising said first and second hinge elements for pivoting the first and second structure means on one another, the first and second locking portions comprising in combination a locking means for locking releasably one to the other, at least one of the first and second structure means including at least one downwardly extending partition element of a predetermined size and shape received between adjacent buttons of a push-button telephone when the locking means is in a locked state, the at least one downwardly extending partition element extending longitudinally along with of the first and second structure means, providing thereby aghinst lateral shifting of the first and second structure means and also providing thereby a deterrent against access to the buttons, each partition element being an elongated thin flange extending downwardly from an upper portion of at least one of the first and second structure means at substantially a right angle thereto, each of the first and second structure means defining a metal strip being shaped to fit around a body portion of a push-button telephone when the first and second structure means are in a locked state.
Claim 4
Dependent Claim 253 words
A button-telephone lock-guard device comprising in combination: at least first and second structure means, one including a first portion of a locking means at a first end thereof and a hinge element at an opposite end thereof, and the other including a second portion of a locking means at a first end thereof and a second hinge element at an opposite end thereof, a hinge means comprising said first and second hinge elements for pivoting the first and second structure means on one another, the first and second locking portions comprising in combination a locking means for locking releasably one to the other, at least one of the first and second structure means including at least one downwardly extending partition element of a predetermined size and shape received between adjacent buttons of a push-button telephone when the locking means is in a locked state, the at least one downwardly extending partition element extending longitudinally along with of the first and second structure means, providing thereby aghinst lateral shifting of the first and second structure means and also providing thereby a deterrent against access to the buttons, each partition element being an elongated thin flange extending downwardly from an upper portion of at least one of the first and second structure means at substantially a right angle thereto, each of the first and second structure means defining a metal strip being shaped to fit around a body portion of a push-button telephone when the first and second structure means are in a locked state.
Claim 5
Dependent Claim 40 words
A button-telephone lock-guard device of claim 2, in which there are a plurality of said flanges extending parallel to one-another and extending longitudinally of at-least-one said metal strips, substantially all of the flanges extending perpendicularly downwardly from the metal strip.
Claim 6
Dependent Claim 28 words
A button-telephone lock-guard device of claim 1, in which the securing means include terminal U-shaped flanges engageable around opposite bottom edges of side walls to a telephone casing.
Claim 7
Dependent Claim 98 words
A button-telephone lock-guard device of claim 1, in which at least one of said first and second structure means comprises two end-to-end metal strips and hinge structure joining two abutting ends of the metal strips, such that one of the hinged metal strips is a pivotal strip pivotable to and fro between an open position and a closed locking position over push-buttons of a push-button telephone, said plurality of parallel flanges extending downwardly from a lower face of the pivotal strip, one of said locking portions being mounted fixedly on a distal free end of the pivotal strip.
Claim 8
Dependent Claim 50 words
A button-telephone lock-guard device of claim 3, in which one of said locking portions is mounted fixedly on a distal free end of one of the metal strips and the other of said locking portions is mounted fixedly on a distal free end of the other of the metal strips.
