Modular public telephone

The invention relates to a public telephone machine

A payphone) installed in telephone booths, that is, in places where the equipment is not monitored by service personnel and therefore has a high potential for extending.

It is widely known that public telephones, and especially telephones equipped with street badges, attract criminals over a long period of time, so these types of phones had stronger frames, more robust sets of buttons, and the common goal was

- Do not break any unit.

IS U.S. Pat. 4638121 is a known handset with a handset on a lever switch. The coin tray at the top has an open end for receiving coins and the lower end guides the coin to the coin storage.

The telephone has a casing with a dial pad. The lever switch lever is solenoid operated and can be pushed into the coin tray Near its open end to hold the coin in a position where it partially protrudes into the upper end of the tray and can be removed by hand.

When the solenoid is triggered, the lever is pulled out of the trough and the coin in the trough enters. the coin repository when the subscriber responds.

IS U.S. Pat. 4645876 The known telephone-machine has a housing with a camera inside. The telephone unit, housed in a housing, has a digital control unit and a telephone handset. The coin-operated switch is built in so that the coin enters the switch. The microprocessor connecting the switch to the telephone unit controls the operation of the telephone unit when the coin triggers the switch. The mounting device is attached to a stationary support. The housing is secured to the mounting device with a lock.

The above solutions were inflexible because of the unobtrusive design of monobloc apparatus, and the use of this type of telephone for a specific purpose is understood as a new realization substantially different from the others in almost the entire manufacturing process.

In addition, in practice, payphones that can work with coins or credit cards, or with any of these two systems, are sometimes required in practice, and to accomplish any of these requirements, such a phone needs to be redesigned because the base structure has not been changed. .

It is also expedient to have a quick and easy assembly, and the assembly of this type of public telephone was difficult.

These types of phones usually have some kind of weak link, which makes them poorly protected, such as a liquid crystal indicator screen that displays information to the user, or an outlet that defects coins.

Another disadvantage of a public telephone is the lack of ability to effectively control the collection of coins, as it depends on the integrity of the collectors, although the coins falling into the apparatus are controlled by electronic means. Theoretical numbers due to machine defects or some consumer tricks can often differ from the actual volume of coins and prevent the operator or cashier from being blinded by the lack of multiple coins.

The public telephone apparatus of the present invention completely solves the above problems. The phone has a modular structure that allows you to insert or remove blocks, as needed, in a rational assembly that is quick and easy. The handset as a whole is extremely durable, virtually indestructible, has no weaknesses, and has full and automatic cash control.

To accomplish all of this, the public telephone of the present invention comprises two blocks: a block having a plurality of operating mechanisms and a bottom block, which is a coin storage box; both units are physically linked and secured to each other by any means that the safe or bottom unit may not be present when the public telephone is designed to work only with credit cards.

The upper and lower blocks have two doors with reliable locks that completely cover the front of the blocks.

The top unit door is a rectangular pan with an inwardly directed cavity, and has a plurality of windows that accommodate the respective modules, namely the top windows side by side, one for inserting a credit card into the phone's credit card module and the other

- Put coins in the coin module. Below them, vertically below, is a window for inserting the data display unit screen, just below it is another window for the dialer, below it a window for the coin return module and another vertical oblong window to the side of those three windows is the window for the module, for hanging up the handset.

In addition, this design provides a large number of covers that can be used to cover some windows, such as removing the credit card insertion module, coin insertion module and coin return module, and even replacing the data indicator module, covers the window with a non-screen display. .

At the bottom of the top unit, and just below the coin insertion module, is a simple coin box that has a sloping area exposed by an external button to release the coins stuck in the coin indicator.

there is a large amount of coins in the storage beneath the coin selector, and the storage is appropriately controlled by the microprocessor of the telephone. The corresponding module, located below the dialer, uses these coins incrementally and appropriately during the telephone call and returns the unused coins at the end of the call. Not all of these items, ie the coin insertion module, the coin selector, the coin return module, exist when the phone only works with credit cards.

The data indicator module is specific in that the front part of the liquid crystal indicator is covered with one or more layers of glass of sufficient thickness to withstand very strong shocks.

The dialer is distinguished by the fact that it has a special dial system on the appropriate dial base, namely a bayonet system, which allows quick and easy dialing, and the dials lock in their positions due to their prismatic polygonal shape. in that correct position they are locked by a common cover containing the windows which, by shape, dimension and position, coincide with the said buttons.

Both modules, the data indicator and dialer module, have long rear threaded screws that are inserted into the holes on the inside of the top unit, the bottom of the mounting pad, and the edges of the pad are specifically aligned with and pressed against the inside surface of the door. nuts, so both of the given modules fit.

The coin return module, which enters the coin from the coin box, has a front open pallet shape and a front hatch with a hinged inward upward door, and the bottom of said coin has an obtuse angular baffle above its rear sloping wall, to the edge, fall into the specified leaning door leaning the door to access it

In fact, the door, leaning against the bulkhead, covers the top of the pallet.

All these modules, especially the front walls, are made of extremely strong material.

Further attention has been paid to the application of hinged, loop-type elements, whereby the ends of the hinged axes engage and engage by connecting the elements to the other elements, forming them and covering the holes in the hoods.

By connecting and securing the handset mechanism to the handset, the cable exits a device on the side of the top unit that allows the cable to tilt approximately 90 °, so that the cable can be conveniently positioned without being damaged.

The top unit door and the bottom unit door are fitted with reliable closures, many slots, and in both cases are opened by an appropriate lock located on the side wall of the unit or remotely from the telephone exchange when required by the operator in the telephone booth. It is important to note the movable lever of the lower unit or safe opening mechanism, which, after loosening a few screws, pushes the door open to open it, which is extremely interesting considering that they are not picked up because of their heavy weight.

when her coins.

sloping

Finally, according to another feature of the invention, the coins inserted into the telephone do not fall directly into the designated bottom block or safe, but fall into the coin box in the safe.

The coin box is characterized by having a sealing cap having a mechanism which, if the coin box is in a safe, detects the holes so that the respective coin vaults in the top block of the S sink into the box and when removed, the said mechanism closes. entrance hole, and the coin box becomes inaccessible. The lid seal must then be removed to allow access to the coins in the box.

FIG. 1 and FIG. 6, it can be seen that the public telephone apparatus of the present invention has two independent units 1 and

2, which may be stacked on top of each other and fixed by conventional means, in addition, block 1 has an operative telephone mechanism, and block 2 has a safe which gradually accumulates coins. It is redundant when the machines only work with credit cards. The front of the unit has the shape of a prismatic rectangular pan with an inwardly directed cavity, a door 3 occupying the entire front of the unit 1, and a safe 2 having a front door 4 not connected to the front unit door.

The upper door 3 has the FIG. Windows 2, 5, 6,

7, 8, 9 and 10 housing the respective modules, namely, the coin insertion module 11C53, the credit card insertion module 12C6J, the data indicator module 13C7J, the dialer module 14C8J, the coin return module 15C9J and the handset hanging module 16C 10J, and some there is no module, for example no module 12, ie when the phone only works with coins, or modules 11 and 15, ie when the phone only works with credit cards, the modules are replaced with matching covers such as the cover 17 shown in detail in FIG. 28-30.

In addition, as shown in Figs. 6, in block 1, below the coin insertion module 11, there is any known type of coin selector 18, below which is a coin depot 19, which holds the coins inserted into the telephone and from which they gradually fall into the safe 2 during the telephone call. the passageways blocks 1 and 2 in channel 20 have opposite openings 21, and at the end of the call, the remaining coins in the coin store 19 fall into the coin return module 15 located below the coin store 19.

The coin-insertion module 11, having the same position number 11, has a plate with a slot 22 therein for inserting coins, and in addition to the convenience of inserting the coin, the slot is considerably expanded. Slit 22 connects to channel 23, whose side walls are flattened and have a downward slope, so that the coin rolls down channel 23 towards outlet 24 shown in FIG.

and Figs. 8 in front of the coin selector 18 entrance 25

Czr. FIG. 6 ?.

It is well known that conventional coin selectors have a sliding side baffle to loosen stuck coins.

To operate this side partition, the coin-insertion unit 11 has a button 26, also mounted in a front panel that can rotate, and the top of the button is made in the form of a tongue with two cylindrical diametrically opposed axes. The button is inserted into the back of the plate 11 and is illustrated in detail in FIG.

10 and the back cover 28 is secured to the plate 11 by screws 29 extending from the plate 11 and having folded strips 30 having transversely spaced ends 27 as shown in FIG. 8, moreover, the back cover 28 is in fact a bracket to which a flat coin channel 23 is attached.

When pressed, the button 26 rotates with respect to the axis of rotation and further has a rear projection 31 inserted into the opening 32 in the cap 28 and a protruding end through a roller 33 pivotally connected to a lever 34 having a free end having a hammer 35 which engages the coin selector. movable partitions with reclining lever. The lever 34 rotates about the axis of the shaft 36 in the middle thereof and the shaft is attached to the flat coin channel 23. A spring 37 is disposed on the shaft which returns the lever 34 after it has been folded down when the button 26 is depressed.

The front panel of the credit card insertion module 12 has a slot 38 behind which is a card reader mounted on the inner surface of the plate 12 having screws similar to the screws of the plate 11 securing the modules to the door 3 using nuts. The data indicator module 13 has a very rigid frame 13 and a window 39, which overlooks a conventional type of liquid crystal indicator with a single or multilayer protective glass 40 that is maximally mechanically resistant. As detailed in FIG. 12, having a step on the perimeter of the metal frame 13, on which is placed a rectangular rubber gasket 41 for supporting the glass 40, furthermore threading bolts 42 are provided from the inside to fix the frame to the cover 3 of the telephone unit top unit. mounted on the back, preferably plastic, with a frame 43 holding the glass 40, and attached to it a printed plate 44 with a liquid crystal display

45 located behind the safety glass.

The data indicator module 13, like the dialer module 14 discussed below, is mounted on the door 3 of the telephone unit top unit 1 by inserting it into the respective windows 7 and 8 until it is supported along the perimeter 46 and using a tray 47 and the bolts 42 through which the nuts 47 are screwed on the outer surface of the pallet pass through the pallet

48.

The dialer module 14 also has a very rigid plate 14, the middle portion of which is inclined slightly inclined, which is well illustrated in FIG. 14 and the bottom has holes through which the dial buttons 49 extend.

More particularly, the plate 14, in addition to the screws 50, such as the indicator module screws 42, for attaching the dialer module to the tray 47, has a further 4 return screws 51 for securing the metal frame 52, which is shown in detail in FIG. 23 and 24, and have holes 53 which are fitted with the corresponding buttons 49 on the dialer.

The frame is positioned between the electrical insulating bracket 59 and the printed circuit board 55. The front surface of the circuit board 55 has an elastic membrane 56 with sectors of conductive rubber 57 located in front of the buttons 49 which engage the labeled circuits upon pressing the respective button. All of these parts are secured to the insulating bracket 59 by carriage screws 58. 17-213, furthermore, in each bracket are provided sockets 60 having cylindrical holes with two protrusions 61 on opposite sides which hold the central bushing 62 guiding the axial shaft 63 of the respective button and the spring 64 rests on the front of the said bushing 62. part and is located in the inner cavity of the button 49 and pushes the button back, that is, when the button is pressed, the spring returns it. Each button 49 is shown in detail in FIG. 205 is a polygonal prismatic shape, hollow, closed at the front, which, in addition to said axial shaft 63, has a cylindrical neck 65 surrounded by a bushing 62. At the junction of the prismatic button 49 and the cylindrical neck 65 are two opposing planar extensions 66 having the shape of a circular trapezoid with a 90 ° apex, each having radial projections 67 on opposite sides, such as small extensions 68 of the socket 60 of the bracket 59. which allow the insertion of buttons and are locked in a defined position by simple rotation, pressing the button 49 in the axial direction 'defeats the resistance of the spring 64 and aligns the lateral projections 67 with the slots 68, then rotates along the internal recesses 69 where the slots 68 are indicated. 175. After assembly in the bracket 59, the buttons 49 are secured by a provided plate or an additional cover 70 having polygonal holes, their number, location, and shape coinciding with the number and location of the buttons 49. The plate 71 is also bolted to the bracket 59 and secures the buttons to prevent them from turning and falling, despite the bayonet-shaped mounting.

The shape, dimensions and position of the windows of the panel or lid 70 also match the windows of the front panel 14 through which the buttons 49 extend outward, but note that when the bracket 59 has the maximum number of slots 60 for the corresponding buttons 49, the panel or the cover 70 must have the same windows as the front panel 14, viz the front visible panel is a security feature of the module and may have the same or a smaller number of windows, but corresponding to the number of buttons provided for the telephone in each case, depending on the particular features of the particular telephone set provided.

The coin return module 15 has a front frame as well

15, whose stepped rear surface 73 sits in the perimeter window 9 of the top unit cover 3, and frame 15 has a large window 74, normally closed by a door 75 rotating about its axis 7uje.

Clamped to the rear surface of frame 15 and fixed by two lateral projections 76, box 77 forms a straight, trapezoidal, inverted profile container or trough open from above and from the front containing said window 74.

It is to be noted that the upper cylindrical edge of the part 75 constituting the container door has two cylindrical projections 78 forming a pivot axis which is inserted into the projections or steps 79 located in the boxes 77 in the upper front corners of the side walls. 25, and the door is locked in the opening direction When the module 1 is inserted, the window 9 of the front door 3 is closed, since the edge of the window 9 covers the recess or steps 79 with an axis 78.

For mounting the module in the door, as in the previous case, four threaded pins 80 are provided on the rear surface of the frame 15, closer to its corners. It is also appropriate to draw attention to the plate 81 provided in the coin return module located above the rear sloping wall 82 of the container, which is shown in FIG. The 27D is also sloping but with a smaller slope. Further, the plate 81 has two lateral wings 83 folded upwards and then outwardly to secure it to the box 77 by bolts 84 in the free and wide holes 85 of the wings 83 allowing the plate 81 with its rear upper edge to fold down slightly. displaced to accommodate the rear upper wall 82 of the box 77, the front lower edge of the plate having a wide and shallow notch 87, 1 supported by the lower edge of the door 75 when, pressing them inside 1 opens them.

In the manner shown in Figs. 27, the coins fall on a plate 81 well distant from the door 75 and fall on the bottom of the container 77. To reach the coins, the door 75 has to be folded inwardly and, when unlocked, together with the plate 81 securely seals the interior of the telephone. Because of the wide holes 85, the plate 81 is sliding and, for coins

If you get stuck, you can jump over the plate.

As stated above, if the phone only has to work with credit cards, it is not a coin return module and window 9 is enclosed in FIG. 28-30, which is a rectangular plate, has the same shape and dimensions and is perimeter 88 with an internal step inserted into window 9, and screws 80 on its rear surface are securely fixed to the door unit 3 of the telephone unit top panel. in former cases.

Finally, the window 10 of the front door 3 of the top unit 1 of the telephone set is for, FIG. 31-36 for a clearly illustrated telephone handset hanging module 90.

The module has a rectangular plate 90, with the same degree of circumference 91 as the previous blocks for insertion of window 10 in the bot, and the same fixing screws 92.

The plate 90 has a top sector 93, which is bolted to a decoration 94, below which is a recess 95, suitable in shape and size for the handset 16, and the lower portion has a front extension 96 forming a slot for the end of the telephone 16, namely a microphone. slot 97 for telephone cable 98.

The lower edge of the penetration 95 has a large step and a window with a small lever 99 which completely covers the specified window and is made of very strong metal, as is the plate 90 of this module and the plates of all other modules.

Lever 99 has two small cylindrical side projections 100 forming a pivot axis 1, inserted into the back of plate 90, enclosed by a bracket 101 to which a telephone handset sensitive knob is mounted 102, and the bracket is a U-shaped plate end projections 103 for securing the bracket to the plate 90 by tightening the nuts 104 on the bolts which have come out of the plate. The front ends 105 of the plates are laterally covered by C as shown in FIG. 36Z) spacing 100 of the shaft 100, with the middle portion of the plate much narrower than the lateral and extending through the trailing edge, at the same time curved upwardly as an extension 106 to which the microswitch 102 is actually attached, and this extension 106 has another extension 107 , in which one end of a spring 108 which engages the bracket 101 with the lever 109, which is part of the lever 99 and actually depresses the microswitch lever 110, is mounted.

Redial button 111,. shown in Figs. 37-39, is anchored below the same plate 90. Specifically, this button 111 is hollow with the inside exposed. At its perimeter 112 is a wing which rests on the step 114 of the stepped perimeter 113 in the plate 90 of the handset hanging module, furthermore said button 111 has an axial shaft 115 which operates a microswitch 116 attached to a corner bracket 117 screwed to the plate. 90 rear wall screws 118 on each side of the Carba windowZ&gt; 114. In addition, as shown in Figs. 39, the bracket 117 covers almost the entire window 114 and has a shaft 115 that passes through a hole 119, along with a support for the spring 120, and the spring pushes the button 111 until the button flange 112, as shown in FIG. 39, leaning on step 113.

The door 3, hinged to the hinges of the telephone unit top unit 1, has a safety lock 121 which interacts with the closing mechanism 122 accessible as shown in FIG. 1, i S one side of the block wall.

The lock is double and has a slider 121 with wide holes 123 as guide projections 124 on the side wall of the top unit. The slider ends 125 extend into the loops 125 'of the door 3, and the ends of the latches are movable by a rod 126 which is connected to a shutter roll 127 moving through a wide opening 128 in the center of the slider 121.

It should be noted that the lock may have an additional interlock controlled by a telephone exchange connected to the telephone. Without the prior permission and the signal from the telephone exchange, the telephone will not open even to join the EU too laterally.

Shielded telephone cable 98 connecting the telephone handset 16 and the apparatus 98 enters the top unit 1 of the apparatus, more particularly one of the side walls of the unit, and the loop mechanism allows the direction of the cable to be varied within the required limits.

Specifically, and more specifically, the side wall of unit 1 has a wide circular hole 129, and a part 130 inserted therein, aligned with the outside of the unit, is made of the same metal as the other outer elements of the apparatus. The piece 130 has a hollow cylindrical neck 131 which is inserted into a block bore 129 and is internally connected to a bushing 132 having a circular collar 133 on which it rests on the inner surface of the block 1, covering the bore 129, and finally screws. 134 is attached to block 1. The neck 131 of the piece 130 further has a step 135 along the circumference that restricts the axial connection between the bushing 132 and the neck and prevents the wall 1 between the collar 130 and the collar 133 of the sleeve 132 from being rotated to prevent the rotation 130 of the piece 130. , FIG. 41 black-staggered, stepped steps that limit the rotation of the workpiece 130, and about 90 ° the workpiece 136 ends. Additionally, the member 130 has a second hollow neck 139 perpendicular to the neck 131, i.e., radially directed, having a clamp 140 for clamping the screen end of the telephone cable 98 which is secured by a screw 142 and forming a continuous channel between the clamp 140 and cavity 131 in block 1. , cavities 143.

The inner safe 2 has a locking mechanism similar to that of the upper unit 1, i.e. the lateral locking mechanism 144 is connected to a shaft 145 having a shaft 146 movable through a wide opening 147 of the slider 148. The slider 148 has wide holes 149 - guide projections 150 located in the respective in the sidewall, and the projections ribs 151 extending into the apertures 152 of the U-shaped transverse 152 on the inner surface of the door 4.

In this case, as a complement to the embodiment described, the front portion of the shaft .145 has a shoulder 153 which terminates on a spindle 154 and Sis pushes as shown in the arrow of FIG. 43, the door 4 when it opens, and interestingly the door, which is seen in Figs. 1, have no handles, they are retracted, as shown in FIG. 43, into the hole in the safe and are needed to protect the safe 2. It is to be noted that the closing mechanism of this door may also have an additional interlock controlled by an S telephone station connected to the telephone, and without the prior authorization and unblocking of the telephone station, the telephone signal will not open even laterally.

Inside Safe 2 is a money-saving coin box with a sealed lid 155 and has a connecting band for this.

156, lugs 157 with holes at one end and at the other edge

158 for stamping. The inner surface of the tooth 155 has an additional wall 159 forming a shallow tray which fits on the inner surface of the lid, is bolted 160 and forms a flat cavity between the two walls.

161 rotating plate 162, which has a window 163 for coins falling into the coin box, coinciding with the same windows 164 and 165 on the outer and inner lid wall, which is clearly shown in enlarged scale in FIG. 45.

The plate 162 rotates about axis 166 with the aid of axis 167 extending from the ceiling or wall of the safe 2, which moves simultaneously in a slot 168 in an auxiliary plate 169 also inserted in a flat cavity 161 and bolted 170 171, so obviously the auxiliary fixed plate 169 has another window for the 172 coins to fall, coinciding with the windows on the inner and outer walls of the lid

164 and 165, preceded by a rotating plate window 163.

This construction has a metal strip 173 which acts on the edge 174 of the rotating plate 162 against its axis 166.

The strip stabilizes the specified member by acting on the brake principle, furthermore, the lower surface of the pivoting plate has an axis 175 movable in the arcuate slot 176 of the auxiliary plate 169, and further has a rod 177 mounted so that it can oscillate on the shaft 178. coupled to a cam 179 mounted on a rotatable shaft 180 having a drive head 180 'which is capable of being shown in FIG. 45, accessed from the inside of the tooth, the rod having an angular gap 168 in which, as shown below, said axis 175 and rotating plate 162 are blocked.

In this embodiment, when in the safe 2, as shown in FIG. 46, a coin box is inserted, a rotating plate 162 occupying a position in which a hole 171 of its slot coincides with a hole 168 of a slot 169. At the beginning of the coin-box installation, the axis 167 of the safe ceiling is over two slits. As the box is pushed into the safe, axis 167 moves along slit 168, pulling plate 162 and rotating it to the extreme position shown

FIG. 47, corresponding to the complete insertion of a coin box into the safe when the rod and cam are in the position shown in FIG. 47.

The position 163 of the pivoting plate 162 coincides with the holes of the top wall of the lid, the auxiliary plate 169 and the bottom or inner wall 159 of said lid.

164, 172, and 165, so that the coins inserted gradually into the telephone set fall into said coin box at the appropriate time, since all said holes are located at the hole 21 connecting the telephone unit or the side unit to the lower safe 2 CFig. 63.

As the coin box is pulled outward, the aisis 167 rotates the plate 162 in the opposite direction. In the final take-off position, with cam 179 in the position shown in FIG. 48, aSis 175 enters the step 171 of the strut 177 and therefore the movement of the rotating plate in the opposite direction is impossible, i.e. coin box i This time the stick cannot be pushed back into the safe and the long piece cannot rotate the plate 162 and match the hole 163 with the other holes in the lid to pull coins out of the box bots.
