  • Patent number: 5524143
    Abstract: A mechanism prevents explosion damage to coin pay telephones by providing an almost horizontal offset in the coin path so that a wad of paper cannot be moved by the weight of subsequently inserted coins. For existing phones, a retrofit provides a horizontal offset by locating a horizontal slot to one side of the existing coin chute entrance and having in back of it a relatively horizontal slippery surface for sliding the coin sideways and then downwards into a tunnel in alignment with the existing coin chute. The tunnel has a sloping bottom surface so that the coin rolls therein under the force of gravity into the existing coin chute. In another embodiment, the horizontal slot is further arranged perpendicular to the existing slot and the relatively horizontal slippery surface slides the coin back towards the horizontal slot and then downwards into the tunnel with a bottom sloping surface operative to roll the coin into the existing coin chute.

    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.

  • Patent number: 5131035
    Abstract: A protective cover is disclosed for coin operated telephones which includes a coin box for storage of coins and a coin return opening for providing the user with a refund of unused coins. The protective cover is constructed of heavy gauge protective steel plate and is dimensioned to extend across the entire width of the telephone while providing limited, but sufficient access to the coin return opening of the telephone by including a relatively small opening to provide such access. A door which blocks the opening in the steel plate is pivotally mounted to the rear surface of the plate and is dimensioned to pivot rearwardly when returned coins are retrieved by the user, thus preventing stuffing of the coin return area.

  • Patent number: 5128993
    Abstract: An improved telephone handset dispenser stores and dispenses a telephone handset and dispenses the handset upon insertion of an implement such as a credit card. A rectangular front face of a generally box-shaped housing has a longitudinal trough defined therein for receiving the handset. Upon insertion of the implement into a slot defined in the front face of the housing, the handset is dispensed for use. The telephone is electrically attached to the housing by a cord. A rotatably cylindrical cord reel dispenses the cord through the longitudinal trough as the handset is removed, and also stores unused cord. Cord is directed between the cord reel and the longitudinal trough perpendicular to the circumference of the cord reel by a cord guide, thereby permitting the cord reel to be centered in the housing with respect to the longitudinal trough. The housing has two sides and two ends, tapered toward the front face to prevent objects from being placed and retained thereon.

  • Patent number: 5029041
    Abstract: A printed circuit path, which connects to a reference potential point, is provided along a portion, or more, of a printed circuit board (PCB) assembly which requires protection from electrostatic discharge (ESD). This printed circuit board path has a plurality of intentionally pointed protrusion integrally formed along its length and which point preferably toward the direction from which the electrostatic discharge is likely to approach the printed circuit board assembly; i.e. through housing mating edges or housing surface openings. The pointed conductor path is locate closer to the ESD regions of concern than other circuit paths or component solder pads. The pointed protrusion preferentially attract electrostatic discharges to itself rather than allow the discharges to strike other paths or components further in on the PCB assembly, thereby avoiding component damage.
