The coin lock to the cashier channel is unlocked under the action of a current impulse magnet

knife test happens, deflects the feeler lever, 20 impulse magnet obeys the cashier impulses, which in thereby a switch releases, whereby this by means of a known manner from the office for each telephone association spring-loaded rotary lever is sent depending on the appropriate fee Storage position is brought and at the same time will be, and that after arrival of the cashier pulse Rotary lever affects a push rod in such a way that the impact movement of the magnet is on the the contact of a second microswitch is closed and transfers the locking lever and the coin lock for

the collection of the coin is unlocked.

A favorable leverage, which only requires a short stroke of the impulse _{magnet, unlocks x} , the coin lock. After unlocking it will

Cashier channel (13) under the action of a current 30 the required spring force for the automatic opening of the push magnet (20) is unlocked by applying the coin lock with a torsion spring.
Impulse magnet obeys the cashier impulses, which Another advantage of the invention is that

In a well-known way from the office for each telephone - only a small mechanical effort is necessary connection has been made depending on the corresponding charge, since the coin lock is locked with a push of the button be sent, and that after arrival of the cashier 35 of the payment button is coupled.

the locking lever (22) transfers and the coin operated inevitably a slightly different operation The lock (21) for collecting the coin (12) is unlocked. and how it works.

2. Table coin phone according to claim 1, not even after lifting the in the drawing

characterized in that the unlocking of the ₄₀ shown handset the speaking guest must insert the coin lock by the current impulse magnet (20) and coin and press the pay button. First

When the coin is checked and in the memory, the speaker can receive the dial tone from the office. Only now he can dial the participant. After the participant has reported, depending on the valid Fee schedule after a certain time the cashier's impulse sent by the office. As mentioned above, This cashier pulse activates the impulse magnet, which unlocks the lock to the coin channel and thus the Releases way for the coins to the cashier channel. If no participant answers or the busy signal sounds, so the inserted, checked and stored coin is automatically activated after the handset is placed on the device directed to the return.

If the coins are too small, the free character is not switched through, since the feeler lever is not deflected and the microswitch B according to patent 24 16 998 is not actuated. The coin immediately slides into the return.

In cases with limited speaking time, an appears

the associated leverage (21,22,23) is triggered, and that the coin lock automatically after unlocking by the torsion spring (23) pops up.

3. Table coin phone according to Claims 1 and 2, characterized in that the locking the coin lock (21) is coupled to pressing the number button (4).

The main patent 24 16 998 relates to a coin checking and cashing device for desk coin operated telephones, which is characterized in that microswitches for the connection of the dial tone from the office are arranged in the coin checking device in such a way that this dial tone is only switched through,

if, after inserting a good coin, the payment button 60 gives a signal for a certain time before the second cashier pulse

printed and this depending on this movement via a pinion and a rack the trigger pin of a slide is transmitted, which on the one hand the contact of a first microswitch closes and the other hand locks the lock to the coin channel, the coin via a pressure plate is pushed that further after the release of the number button the coin is a sensing lever for the purpose of

z. B. optical or acoustic type, with the speaking guest within a period of time a new one Insert a coin, otherwise the connection will be disconnected.

An exemplary embodiment of the invention is explained below with reference to the drawings. It shows

F i g. 3c a partial view of the coin checking and compulsory payment device, which shows the scanning of the coin to the minimum diameter and the deflection of the switch in the storage position,.

F i g. 3d a partial view of the coin checking and compulsory payment device, from which it can be seen how the impulse magnet is activated after the receipt of a cashier pulse is activated, which unlocks the coin lock,

F i g. 4 is a view of the coin checking and compulsory payment device according to FIG. 1, but now in the memory position,

F i g. 5 is a view of the Münzprüf- and compulsory payment device according to Figure 4, but after Triggering of the impulse magnet and unlocked coin block.

The basic mode of operation of the invention according to FIGS. 1 to 5 is the coin validator for two operating modes and compulsory payment device shown. The reference symbols for the individual components are the same as in the main application P 24 16 998 shown.

I. Operating mode 1 for the normal local coin without speaking time limit and

II. Operating mode 2 for the normal local mint with speaking time limitation.

Operating mode 1

35

The mode of operation 1 works as follows; As already known, after the handset, not shown in the drawing, has been lifted off, the coin 12 is thrown through the coin screen 2 (FIG. 1) into the housing 1 of the coin testing device and checked for maximum diameter. F i g. 3a shows how the coin falls into the housing and rests on the pressure plate 6. If the coin is inserted, the number button must be pressed as before, so that the dial tone is now switched through by the office, otherwise the device remains switched off. After pressing the number button 4, this movement is transferred, as is known, via the pinion to the rack of the slide 3, which now fulfills two functions compared to the known device, namely once the closure of the contact from microswitch A as known, and on the other hand the locking for Coin channel (Fig.3b). After releasing the number button 4, the coin 12 is checked by the feeler lever 7 and the switch 8 is rotated into the storage position (FIG. 3c) and the micro switch B is switched. The dial tone can now be switched through and the subscriber dialed. The coin is now cashed automatically, without any interference by the speaking guest, in that after the participant has reported, the office sends cashier pulses after a certain time, depending on the applicable fee schedule. These impulses are obeyed by the current impulse magnet 20, which unlocks the coin blocker 21 via the locking lever 22 (FIG. 3d) so that it springs open by a spring force 23. The coin enters the cashier channel.

After the call has ended, the handset, not shown, is switched to the hook switch in a known manner laid and as described in the main patent 24 16 998, the switch back in the rest position or return position switched and held.

Operating mode 2

In this operating mode, local calls are time-limited and must therefore after the time unit has expired to be paid in arrears.

As described at the beginning of the operating mode 1, the coin 12 is checked, stored and replaced by the first Charge impulse collected. A certain time before the arrival of the second charge pulse is now In addition, a signal is sent, with the speaking guest receiving a new coin within a period of time must throw in, otherwise the connection will be disconnected.

If no participant answers or if the busy signal sounds, the handset must be hung up. The coin can then be removed from the return without the number button as in the main patent 24 16 998 must be pressed, because the hook switch by its weight of the Handset directs the switch with the already stored coin into the return position and the Soft holds on.
