Public telephone set

(57)

The device is of modular construction and consists of two superimposed bodies (1, 2), of which the upper body (1) contains the telephone mechanism itself and the lower body (2) a coin box, by which the telephone is activated. The upper body door (3) has a plurality of windows for mounting each module, namely a coin module (11), a credit card module (12), a display module (13), a button module (14), a coin return module (15) and a module to hang up the handset (16).

The invention relates to a public telephone apparatus which is mounted in a telephone box and the like, i.e. in places where there is no direct personal control over it, and therefore there is a risk of theft of its contents.

It is known that public telephones, especially in street telephone booths, attract criminals and must therefore have increasingly durable cabinets, keypads and must be designed in such a way that all their parts cannot be damaged.

However, the solutions used so far are not flexible, since they are designed as a one-piece structure that cannot be changed, so that each particular application for a given type of phone represents a design that differs significantly from the others virtually throughout production. However, practice requires that only coin-operated telephones, credit-card-only telephones, or both, can be provided, so that a telephone must be provided which, with an unchangeable basic design, meets both these types of payment. It is also desirable that, despite the robustness needed, the installation of a telephone be quick and simple, while conventional phones of this type require complex installation.

Another problem with this type of telephone is the existence of certain vulnerabilities. which lead to easy damage, such as a glass display screen, on which the information is for the user. or outlet channel for excess or damaged coins

Another problem with public payphones is the impossibility of effective control of withdrawals, which therefore depends solely on the honesty of the collector; even though electronic devices for counting the coins to be inserted are arranged in the machine, the theoretical number may not correspond to the actual number due to machine malfunctions or various tricks used by some users. The lack of several coins cannot therefore be easily attributed to the ward.

The public telephone set according to the invention fully solves the above problems and has a modular structure which allows the use or discarding of certain components of the device, even though it does. tazi. it is very robudhí, almost impossible to damage, has no weaknesses, and the selection of the accumulated coins is completely and automatically controlled,. The public telephone apparatus according to the invention consists of two bodies, the upper body being provided with a single working mechanism and the lower body acting as a coin collecting box, the two bodies being mutually independent and can be connected to each other by any suitable means: the lower body or the money box does not have to be arranged in the device, especially when the phone is to be used only with Credit Cards.

The door of the upper body in the form of a rectangular pan with a cavity open to the rear are provided with several windows for connecting the individual modules. in particular, there are two upper windows lying side by side, one of which is used to fasten the coin insertion module and the other for credit card insertion. Vertically beneath them is a window for mounting the display module, below it is a window for mounting the module forming the keypad, and below it is a window for the coin return module. Along the last three windows there is another handset hook module

Said structure is further provided with a plurality of turrets which can be attached to individual windows, in particular to replace a coin module, a credit card module and a coin return module, and optionally to replace a display module in those practical embodiments where it is considered unnecessary. .

At the bottom of the upper body just below the coin mod^atThe rim is a conventional coin collector, which has a pivot lever operated by an external button for normal and necessary action on the coin selector, which allows the coins to be jammed in it.

Below the coin selector is a coin stack that can accommodate a considerable number of mines by a telephone microprocessor and which is controlled to allow for a gradual utilization as the call is continued in the relaunch of the call.

which is through the corresponding system. Of course, all these modules located below the button elements, i.e. the coin module, the coin selector, the coin magazine and the coin return module, are omitted in those practical embodiments where the phone is to be used exclusively with credit cards.

The display module is characterized in that the front side of the liquid-crystal screen is protected by a single or laminated glass of sufficient thickness to withstand severe wounds.

The keypad is characterized by this. The system for mounting the pushbuttons on the carrier is designed as a bayonet assembly which allows a very fast and simple mounting of the M-Ί 1JO S'3.5. 31 \. Due to its shape, the mouthpiece, preferably a prism, is fixed only by a common lid provided with windows which correspond in shape, size and position to the buttons.

Both the display module and the push-button module are provided with large screws which pass through the openings of a kind of pan located inside the upper body, the opening of which corresponds to the inner surface of the door, the latter being tightened when it is pulled.

the coin return module into which the coins come from the magazine is shaped like a forward box with a front sloping wall, the bottom of this box having an oblique partition, which is hit by the free edge of the front flap when swiveling . That is, when the box is open to remove the respective coins, the partition closes the upper end of the channel through which the coins fall.

All modules, especially their fronts, are made of very strong and durable material. Attention is drawn to the pivoting suspension of the individual pivoting elements so that the ends of the shafts around which they oscillate fit into the holes specially designed for them and are definitively fixed when the individual elements are joined, thereby closing the holes for these shafts.

The telephone cable, connected to the whole device and to the handset, is shielded and the side wall of the upper body of the device is provided with an opening for the cable, where a mechanism allowing a certain oscillation of approximately q0 ° is arranged so that the cable can have any direction relative to the device it has been damaged.

The safety locks for both the upper door and the lower door contain a large number of bolts and screws and open in both cases by means of a suitable bolt, located on the side wall of the housing or remotely either from the telephone exchange or The housing, where the coin box is, is a drive arm which, upon loosening a group of screws, acts on the door in the sense of opening.
