Abstract
Description
- The present invention relates to a remote monitoring device for safety doors for safekeeping means, vaults and the like.
- The aim of the present invention is to provide a device which can remotely monitor all the functions of actuation and management of the moving parts in a safety door, i.e. the rabbet, the lock or locks, the bolts, etc.
- A further object of the present invention is to provide a device which is easy to apply and manage and has a high degree of reliability.
- This aim, this object and others which will become apparent hereinafter are achieved, according to the present invention, by a remote monitoring device for safety doors and the like, which comprises an electronic control computer, a plurality of sensors located in preset positions on the safety door, interface conversion means located between the sensors and the computer, and locking means driven by the computer.
- Further aspects and advantages of the present invention will become apparent from the following detailed description of some preferred but not exclusive embodiments thereof, illustrated only by way of non-limitative example with reference to the accompanying drawings, wherein:
- figures 1 and 1A are views of a printed circuit arranged adjacent to a safety door lock;
- figure 2 is an enlarged-scale front view of the printed circuit of figure 1;
- figure 3 is a view, similar to the view of figure 2, of a printed circuit associated with a mechanical feeler;
- figure 4 is a schematic view of a moving contact which controls a potentiometer;
- figure 5 is a partial schematic view of a multi-pin bolt provided with a moving contact;
- figures 6 and 7 are views of two further embodiments of the printed circuit mounted so as to be controlled by a lock; and
- figure 8 is a block diagram of the connection of various sensors for monitoring a safety door, connected to a remote centralized processing unit.
- In the various figures, identical or similar parts or components have been designated by the same reference numeral.
- With reference to the above figures, the
reference numeral 1 generally designates a mechanical lock which can be operated by means of a key (not shown) which can be inserted in anopening 2. Thelock 1 is provided with abolt 3 and withfixing holes 4 and can be seated in or onto a safety door (also not shown) for safekeeping means, such as safes in general, vaults and the like. - A printed
circuit board 5 can be directly fixed to thelock 1, for example by means of three or more fixing screws -- not shown in the drawings -which pass throughholes 6. An electromechanical component, for example anelectromagnet 7, capable of interfering with at least one movable element of thelock 1, such as a plate, foursensors connectors board 5. Thesensors respective bolt 3 of the lock (assumed to be provided with two bolts), whereas thesensors shaped opening 15 of the board 5 (see also figure 8). Thesensors 8 to 11 may be of any suitable type, such as infrared sensors or magnetically-acting sensors, capable of detecting the states of certain mechanical elements of thelock 1 and/or of other movable elements, such as keys, bolts, rabbet, feelers and the like. Theconnector 12 is meant to establish an electrical connection with a remote sensor, typically a sliding-contact resistive sensor orpotentiometer 14, as will be explained hereinafter, whereas theconnector 13 is meant for connection to an electronic control computer. - Figure 3 illustrates a printed
circuit 5 provided with apotentiometer 14, with which a rod ormechanical feeler 16 can interact; said rod orfeeler 16 can be loaded by areturn spring 17 and is mounted so that it can slide with respect to thepotentiometer 14 but so that it is rigidly associated in motion with thebolt 3, for example by means of alinkage bracket 18 fixed to the bolt. - The
potentiometer 14 can be of the type with a moving contact which moves either along a straight path or along a path which curves about an axis, but is in any case suitable to transduce the position of thefeeler 16 with respect to ajamb 19 against which thelock 1, and thus the door on which it is installed, is to be closed. Thejamb 19 in turn can have an accommodation andengagement seat 20, for the end of thebolt 3 which protrudes from the lock, having a plurality ofdepth levels 21 and 22 (preferably specific for each safety door, i.e. non- repetitive): one for the bolt and the other for the feeler. - The
feeler 16 can be partially rigidly associated in motion either with thebolt 3, as in figure 3, or with the expansion elements (bolt plates) 23 of the bolt or bolts, as shown in figure 5. - In the embodiment of figures 4 and 5, the rod or
feeler 16 is supported in a cantilevered manner by thebolt plate 23 or by a boltplate locking expansion 24 and is slideable with respect to apotentiometer 14, which is fixed to the bolt plate, in contrast with aloading spring 17 which at one end abuts against anexpansion 26 or a sleeve whose position can be adjusted and abuts against thepotentiometer 14 at its other end. At its cantilevered end, therod 16 supports asliding roller 25 for the frictionless abutment against aseat 22 for accommodation in thejamb 19. The signals emitted by thepotentiometer 14, as mentioned above, are transmitted, by means of acable 27 connected to theconnector 12, to anelectronic control computer 28, as schematically shown in figure 8. - In the embodiment of figure 6, similarly to the one of figure 2, the lock requires no additional mechanical components except for one or
more abutment protrusions 29 and one ormore engagement recesses 30 to allow the locking and release of anengagement element 31 which can be actuated either by theelectromagnet 7 or by a reversible electric motor 32. - The recess or
recesses 30 can be defined on the bolt or on one or more plates which move rigidly with thebolt 3. - The
actuation components 7 or 32 can be mounted on theelectronic board 5, and engage bolt abutment elements or directly engage the bolt itself, as in figures 6 and 7. - Figure 7 is a view of a
lock 1, in which anengagement element 31, actuatable by anelectromagnet 7 or by a reversible electric motor 32, can engage in arecess 30 defined in aplate 33 provided for this purpose, slideable onfixed guides 34 transversely to the direction of motion of the bolt; said guides are provided with a tooth orabutment 35 which engages ashaped recess 36 with two positions provided in thebolt 3. Theplate 33, when released by theengagement element 31, can be actuated by the key for opening and closing the lock in order to allow the forward or backward movement of the bolt. - Figure 8 illustrates the block diagram which shows the connections of the various electronic components controlled by the
lock 1. - The signals which arrive from the various sensors, i.e. from the
sensors sensors 8 for the first bolt, from thesensor 9 for the second bolt and from thesensor 14 for indicating the adjacent or non-adjacent position of the safety door with respect to thejamb 19, are sent along four separate inputs C1, C2, B and K to a digital-to-analog converter 40, with, for example, 16 output voltage levels, whose output is connected to thecomputer 28. - With this arrangement it is possible to have the following combinations of states. If the four inputs are all at
level 1, this means that the rabbet of the safety door and the bolts are closed and that the key is in the keyhole; if inputs C1, C2 and B are atlevel 1 and input K is at level 0, this means that the bolts and the rabbet are closed and that the key is not inserted; if inputs C1, C2 and K are atlevel 1 and input B is at level 0, this means that the rabbet is open, the key is inserted and the bolts are closed; if inputs C1 and C2 are atlevel 1 and inputs B and K are at level 0, this means that the rabbet is open, the key is not inserted and the bolts are closed; if input C1 is at level 0, input C2 is atlevel 1 and inputs B and K are atlevel 1, this means that the rabbet is closed but that only the second bolt is closed and the key is inserted; if C1 and K are at level 0 and C2 and B are atlevel 1, this means that the rabbet is closed but that only the second bolt is closed and the key is not inserted; if C1 and B are at level 0 and C2 and K are atlevel 1, this means that the rabbet is open, that only the second bolt is closed and that the key is not inserted; if C1 and B are at level 0 and C2 and K are atlevel 1, this means that the rabbet is open, that only the second bolt is closed and that the key is inserted; if C2 is atlevel 1, whereas C1, B and K are at level 0, this means that the rabbet is open and the second bolt is closed; if C1, B and K are atlevel 1 and C2 is at level 0, this means that the rabbet is closed together with the first bolt and the key is inserted; if B and C1 are atlevel 1 and C2 and K are at level 0, this means that the rabbet and the first bolt are closed and that the key is not inserted; if C1 and K are atlevel 1 and B and C2 are at level 0, this means that the rabbet is open but that the first bolt is closed and the key is inserted; if B, C2 and K are at level 0 and C1 is atlevel 1, this means that the rabbet is open, the first bolt is closed and the key is not inserted; if C1 and C2 are at level 0 and B and K are atlevel 1, this means that the rabbet is in contact with the jamb but that no bolt is closed and the key is inserted; if C1, C2 and K are at level 0 and B is atlevel 1, this means that the rabbet is in contact with the jamb, the bolts are open and the key is not inserted; if B, C1 and C2 are at level 0 and K is atlevel 1, this means that the rabbet is open, the bolts are open and the key is inserted; finally, if all the inputs are at level 0, this means that the rabbet is open, the bolts are also open and the key is not inserted. - The
computer 28, in a central control station, can thus intervene according to a program, in hazardous situations, on any one of a plurality of remote safety doors by emitting an output signal directed to anactuation element 7 or 32, locking or interfering with the lock and thus locking the rabbet in the closure position. - One or more display monitors for visual surveillance of the situation of the various remote safety doors may naturally be associated with the
computer 28. - As can be seen, with the monitoring device according to the invention, the
mechanical lock 1 acquires additional functions which combine synergetically with the original ones. However, the specific capabilities of the lock remain unchanged if the monitoring device is removed, in which case the lock can operate with a normal key-based manual actuation. - The invention as described above is susceptible to numerous modifications and variations within the protective scope defined by the content of the following claims.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.
