Description
SPECIFICATION
An Electronic Safety Locking Device for Suitcases, Trunks, or the Like
The present invention relates to an electronic locking device the operation thereof is based on the principle of combining- the electronic-counting number, as generated in a device representing an electronic key, and the corresponding electroniccounting numberofa device contained in a safety locking system.
As it is known, the safety locking devices are made by means of conventional mechanic systems or by numerical combinjation locking elements, which may be partly opened, or unlocked, which require mnemonic efforts by the user and which are difficult to be used in the case of poor visibility and as the user has a rather bad sight.
The aforesaid drawbacks are, on the contrary, eliminated by the use of the device according to the present invention.
In fact, by using the instant safety locking device particularly for suit-cases and the like, the mechanism for using an especially provided electronic key does not require any particular expedient, since it is sufficient to merely pluginsert said key in the circuit applied to the suitcase or the like, by an operation which is completely like to that of inserting a plug into the related socket.
Furthermore, for each connector type or model are possible thousands of different electronic combinations, thereby being possible to obtain numberless combinations, simply by passing from a series to the next one, merely replacing the connectors located respecively on the key and on the lock.
Each electronic key may be provided with a matriculation code, printed on the lock itself, thereby permitting to obtain key duplicates in a loss case.
The locking and un-locking operations of the suit-case may also be carried out manually, as in the conventional types of suit-cases, and, furthermore, they may be carried out by operating a small plug-in lever associated to the electronic safety locking device, which lever prevents any attempt of unlocking said lock, unless the corresponding electronic key is used.
Since said electronic key isoperated or actuated by an electric battery therein contained, in order to prevent said battery from discharging, said electronic key is provided with a signalling light, effective to signal to a user the discharged condition of said battery for the replacing.
The electronic safety locking device according to the present invention, is based on the simultaneous electronic-counting principle performed by two binary electronic counters each driven by an oscillator located in the lock mounted on the suit-case, and by an electronic circuit contained in said electronic key.
Said electronic counting is simultaneously started in the two pulse counters, by pressing
down the push-button the electronic key is
provided with.
At the end of the counting as predisposed or
set in each said counters, said electronic counting
is ended and only if the two counters end the
count on the same digit, is actuated the circuit
driving the coil for unlocking the lock.
The aforesaid different counting combinations
are obtained by using two binary counters, for
example of the 1 4-stage type which are able to
count up to 213.
At the outputs of the counters, by means of two diodes, a digit is set corresponding to the lock
unlocking code, that is to the number of pulses which the counters have to count, before allowing for said lock to unlock.
If the two diodes are inserted in the analagous positions of the two counters, at the time at which the outputs will be of positive value, the counting up of said two counters is stopped by means of an inverter, and a transistor goes to its saturation state thereby pulling the keeper and permitting said lock to open.
As for unlocking said lock one uses a key which is different from that supplied with the lock, then two cases may occur: 1) the key combination has a number greater than that of the lock; in this case as the key preset output becomes positive, the transistor does not pass to saturation since it is held at O by counter;
2) the key combination has a number less than that of the lock; the reasoning is similar to he preceding one, since, also in this case, said transistor does not saturate, being held at zero by the key counter.
The device according to the present invention and the operative and structural characteristics thereof will become more apparent from the figures of the accompanying drawings, in which:
Figure 1 is a top view illustrating a suit-case or trunk provided with a safety electronic lock, consisting of an electronic circuit, which is actuated by an electronic key in turn comprising a corresponding driving circuit;
Figure 2 is a side cross-section illustrating the electromechanic lock to be applied to suit-cases, trunks and the like, according to the present invention;;
Figure 3 is another cross-section view illustrating that same lock, in which are shown the multiple socket for plugging-in said electronic key, a locking electronic transistor panel and a signalling light, effective to signal the unlocking of said lock and the discharged condition of the battery as, with the lock in an unlocked condition, said light does not wink;
Figures 4, 5 and 6 are respectively side, front and cross-section views, illustrating an electronic key, in said cross-section view being furthermore represented the driving electronic transistor panel included in said key;
Figure 7 illustrates an exemplary detailed electronic diagram of the instant locking device; and
Figure 8 illustrates, by a block diagram, the operating principle of the electronic safety locking device according to the invention.
Referring particularly to the numbers of the several figures of the accompanying drawings, the electronic safety locking device according to the invention comprises a mechanic part and an electronics part, this latter being divided and distributed in a key (21) and a lock (22), said key (21) comprising a decoder and a binary comparator while said lock comprises an oscillator and a decoder.
This system is able of permitting the carrying out of numberless different combinations, as preprogrammed in the two electronic circuits during the making step.
Said two electronic circuits are preferably formed on a fiber glass support being provided with electrolyte copper paths and tin-lead pattern.
All the components are of the solid state type, and the integrated circuits are of the "CMOS" type, the discrete components being of the silicon type.
The schematic diagram is illustrated in figure 8 where (23) indicates an oscillator, (24) a code, (25) an encoder, (26) a decoder and (27) a code.
The operation of the instant electronic safety locking device provides for the using of a key (21) having a plurality of plugs (21') which are inserted into corresponding sockets (28) forming a connector (I).
As it is shown in Figure 7, by pressing down the aforesaid push-button (2), upon having inserted the key (21) into the sockets (28), the circuit "R/l", "C/I", generates a reset pulse clearing the two counters "M/l", "M/2".
Simultaneously the oscillating circuit formed by "R/2", R/3" and "C/2" and by the inverters "I/l", "1/2" and "1/3" starts to generate a square wave which, at the same time at which the reset imputs of the counters return to "zero", causes said counters to count up. Said counters are two multiple-stage binary counters effective to provide very high counts.
At the output of said counter, through the diodes "D/l" and "D/2" a digit is set provided for constituting the unlocking code of the lock, that is the number of the pulses which have to be counted by said two counters, before permitting said lock to unlock.
If the two diodes are inserted on the analogous positions of the two counters, at the time at which both the outputs thereof pass to the 1-state, through the inverter "1/4", the clock to the two counters is disabled, and the transistor "T/l" will saturate, thereby causing the transistor "T/2" to pass to the off state, which transistor "T/2" will in turn saturate the transistor "T/3" thereby energizing the coil (8) which will pull up the keeper (7), in such a way as to remove the impediment to the unlocking of the lock due to the presence of the keeper (6).
As for unlocking the lock one uses a key different from that supplied with the lock, two cases may occur:
10) the key combination has a number greater than that of the lock: in this case as the output preset by the counter "M/2" goes to "1", the transistor "T/I" will be not driven, since it will be held at "zero" by the counter "M/l";
20) the key combination has a number less than that of the lock; the reasoning is similar to the preceding one, with the exception that this time will be the counter "M/I" to firstly pass to "1" and "M/2" to hold in an off condition the transistor "tit".
The combinations which may be obtained, for example, may be given by 213+212+...
23+2 =8186 times the possible combinations due to the five contacts of the connector. If, due to safety reasons, the positions of the two power supply terminals are not varied, then the remaining three terminals provide six possible combinations, which, multiplied by the preceding combinations, provide a possibility of making 49116 different combinations.
In order to permit to monitorthe battery status, in parallel to the driving coil "8" a "LED" (14) diode has been connected. Said "LED" will turn on each time the lock is operated, and only as the battery voltage will drop for example under 6V said LED will be off due to the Zener diode series connected with respect to said LED. In this case the lock will be capable of operating, but the user will know that the battery has to be replaced.
The electronic safety locking device according to the invention comprises furthermore a battery (4) effective to supply current to the coil of an electromagnet (8), which is able of exercising a pulling action on the end (7') of a keeper (7) able of oscillating on a pivot (38), a spring (31) biassing said keeper (7) against the end (6') of said lever (6) as said electromagnet is disenergized.
The aforesaid lever (6) may swing on the pivot (33), and is provided with a spring (32) biassing
upwardly the end (6") of said lever (6) and biassing downwardly the end (6') thereof.
The instant device comprises furthermore an opening and closure sliding element (5) in turn provided with a top ridge (34) thereagainst abuts the end (6") of said lever (6).
As said sliding element is in a locked condition,
it presents the locking member (22) from
unlocking, said locking member being pivoted to a fixing member (11).
The plugging in of the device for locking said
sliding element (5) is obtained by the push. button (12) effective to upwardly slide, in such a way as to upwardly move the end (6') of the lever (6), while the end (7') of the keeper (7), by moving
under the end (6') of the lever (6), preverits this
latter from sliding the unlocking and locking
sliding element (5).
The unlocking of the instant device is obtained
by inserting the key (21) in the multiple socket (9)
which is electrically connected to the electronic
transistor panel of the lock (10) which panel
provides the power supply to the electromagnet
(8).
This latter, by pulling the end (7') of the keeper (7), causes the end (6') of the lever or keeper (7) to lower and hence the sliding element (5) and locking member (22) to unlock.
The instant device also comprises an electronic key (21) provided with a plug-in type of multiple connector (1) including a plurality of plug elements (21) to be inserted into corresponding sockets (22) formed in a multiple socket (9) for the key.
The aforesaid electronic key (21) is also provided with an electronic transistorizated panel (3) which, jointly to the electronic transistorized panel;(1 0) included in the locking device proper, is effective to drive the mechanical part of the lock for unlocking said lock.
It should be noted that the electronic safety unlocking device according to the invention has been thereinbelow described and illustrated only as a non limitative example.
Accordingly, to the electronic safety unlocking device according to the invention modifications and variations may be brought without departing from the invention scope.
