[0001] The sector of the technique invoked in this patent is that of locks, and particularly
those for locking doors whose closing operation is vertical, sliding or tilting. It
is also the field of locks for electrically operated doors.
[0002] Statement of the prior state of the art. E90904411 for an electrical lock operating
device, especially for motor vehicles, made up of an electrical motor which drives
an endless screw or worm unit; this is housed in a part of the frame of the device
which forms one sole piece with the part of the frame which houses the electric motor.
[0003] Recently remote control units have become well-known in systems for unlocking vehicles
for example. Outdoor blinds and vertical doors are operated at present by motors which
avoid the human work of lifting and lowering these by hand.
[0004] Nevertheless locks which can combine both systems, that of motor-driven lifting and
operation by remote control, have not yet been heard of.
[0005] Unlocking this kind of locks and this kind of doors invokes a series of difficulties
stemming from the fact that the lock action has to be internal, as otherwise the lock
cannot be efficient because it could easily be forced. Furthermore, the fact that
the blind or door mechanically separates from the lock presents problems stemming
from the particular adjustment of each item, and as we will see further on in accordance
with the solution for this problem.
[0006] This invention presents a combined operation lock which, though it can be mechanically
operated, can also be run by remote control and is electrically operable, thus electronically
determining the situation and anomalies of the locking operation.
[0007] There is also a description of an embodiment of the lock consisting in a communication
system using two codified units, one external and another in the lock, which are in
a permanent dialogue situation, so that the motor can only be operated when both units
are in proper communication, and consisting of the set of internal and external devices
for detection of the status of the door and consequently the means for carrying out
opening or closing operations.

[0029] The anchorage 1 has a central form fitted with annular reinforcements 6, whose lower
part has rings 7 for securing these, and its upper part has an edge 5 which aligns
with the outer surface of the place in which this is encased. This can be of the type
which is threaded to the body of the anchorage 1. The inner part with its annular
reinforcements 6 has an internal widening 48 which can retain the balls 14 held in
the rod when these come through the ports opening in the lower side of said rod. The
anchorage has an internal plunger 9 set on a spring 11 which has a recess 12 which
limits its travel upwards in respect of a threaded ring 10 which is inserted in the
inner thread 8. Through the effect of an upward pressure the upper surface of said
plunger 13 gives way until it is lodged in the lower end of the anchorage (fig. 4).
[0030] The rod 3 is joined by means of a thread 32 to the body 2, and can be locked by means
of fixing 47. This thread can also constitute a regulation of the length of the rod
3. Said rod 3 contains the devices for locking and unlocking in respect of the anchorage.
[0031] One embodiment of the rod 3 could be joined by means of a pin device with the same
effect.
[0032] The assembly has for example one or two locks: when installed in a door, one of these
is in a position to be operated from the inside of the premises and the other, fitted
with a cover 16, from the outside.
[0033] The body 2 operates the assembly for the corresponding closing and opening operations.
It can be operated by means of the outdoor lock 15, by the indoor lock 17 and by an
electrical impulse.
[0034] The advertising and informative cover is a part that can be lit up but is not inherent
to the locking device strictly speaking, and is formed of a cover which matches the
body 2 in shape and size, and has a channel 45 through which cables can be threaded
for its electrical connection 46. It has selective lighting and for example words
such as "open" or "closed" or alarm or locking failure symbols.
[0035] The part next to the end of the rod 3 has two balls 14 that can protrude through
the two through holes 49, of greater diameter than these and becoming narrower at
their outer ends by annular neckings 50, which enable a range of movement covering
the cylindrical space lying between them, without letting them drop out.
[0036] A preferential embodiment consists in the one shown in figures 15 to 19, which will
now be explained.
[0037] This embodiment is totally based on the electronic configuration of the two units,
lock and motor control. According to this basic scheme, there needs to be a microprocessor
in the lock, which is set in the housing 63, and a microprocessor in the outer unit,
not shown. The logical system for communication between both microprocessors is highly
complex, but can be schematically expressed in such a way as to outline the basic
functions. Both microprocessors establish a dialogue so that they can recognize each
other. Apart from the recognition code, the lock sends out a status code, which enables
the outer unit to react according to said status. One special function of the lock
processor is to inform of the lock status. Whether dealing with one or two locks,
the motor must be aware that the door lock is open, to allow motor-driven opening,
for if not the motor could operate inefficiently, burn out and furthermore not open
the door. For this reason, in this function, when the remote control unit informs
it that it should open, the motor gives the order to the lock to open. If the lock
does not open, it informs the motor of this circumstance. The motor turns in reverse
to free the balls 14 from its tension. The verification process is continuous, especially
if there are two or more locks on the same door. When it receives the information
that both are open, the motor lifts for the time required and predetermined for the
door to be opened.
[0038] The closing operation is carried out by means of a similar function the other way
round. From the top position, the closing order determines the order in the motor
to lower the door. Detection in the motor of the operation being concluded takes place
by means of the pressure of the rod 20, and a combination of codified impulses which
identity the proper closing. The limiter is bar 20. Otherwise, if the coding is not
correct, the electronic device gives an order to reactivate the system, being set
open again and ready to receive the closing codes. A detector 79, 80 connected to
the electronic system, verifies the impulses, so that the door is left closed. Said
impulses are made, in respect of the contact 80, by the top of the cap which commands
the bar 56 of the pusher moved by the pusher 30 in relation with the movement of the
balls on going through the narrowing of the anchorage 1; as regards the contact 79,
by the lowering process, caused by releasing the thumb latch 70 which holds underneath
the bottom of the cap 60. The thumb latch 70 has a pin 71 which is contacted by the
ball 76 on being pushed by rod 20 set in a recess 77 formed by the cam pivot 73, temporarily
moving the thumb latch by the lifting motion, and said latch returns to its initial
position by means of the spring 75. Once at the top the ball is free to drop, recovering
the hollow 77, and becoming operative once more. The triggering for the closing operation
acts in this way. Nevertheless the closure is definitively determined as follows:
said detector has the two contacts already mentioned, one at the top 80 and one at
the bottom 79. Closing occurs when both are in agreement, as if the lock were to be
manually triggered by means of the closing rod 20, closure of the lower contact 79
would occur without the upper one having received the coding, so that the electronic
system would give the reactivation order, lifting the cap to the top position waiting
for the mechanical triggering to be in accordance with the electronic prompt.
[0039] This can be used in industrial applications for making lock closure devices and especially
those which are combined with motor-driven and/or manually operated movement doors.
