Abstract
Vaults for financial institutions, night depositories, and automatic teller machines generally have, for access and egress by employees of the financial institution, a mechanical rotary dial lock. Greater security is achieved with a programmable digital lock, now available to the industry and the invention is an adaptor plate assembly which is mounted on the inside vault door over the housing for the rotary digital lock so that the rotary digital lock and its inner tumbler mechanisms can be removed and replaced with the programmable digital lock without the need to alter any of the mechanical levers or sliding bolt arrangements normally mounted on the internal surface of the vault door and which, when latched closed by the prior art combination lock or, according to the invention, by or the programmable digital lock.
Description
CA 0221~080 1997-09-09 SECURITY LOCK INTERFACE
This invention relates to a security lock interface.
More particularly, the invention relates to a mechanical interface adaptor, which when mounted on the interior surface of a vault door, permits the substitution of a conventional mechanical rotary tumbler lock assembly, commonly referred to as a combination lock or conventional mechanical dial lock technology. The dial lock is designed to actuate access into the vault by releasing for movement one or more sliding bolts mounted on the interior vault door.
Generally, the sliding bolts are slid to and fro by a movement on the outside of the door of a bolt actuating lever. The dial lock permits the sliding of the bolt when the dial of the lock is rotated clockwise and counterclockwise to the appropriate sequential numbers on the dial. The mechanical interface adaptor permits the replacement of the mechanical dial lock with a programmable digital lock actuating assembly without the need for tampering or adjusting any of the existing mechanical sliding bolt assemblies.
PRIOR ART
Presently, in vault safes for banks, financial institutions and in other facilities including night depository boxes, and for access and egress into automatic teller machines (ATM), the primary access method or technique has been to use mechanical dial lock technology to latch and unlatch the vault door whereby to again access into and egress out of the vault.
In certain applications, the mechanical dial lock is also time actuated in that one must be at the vault at a certain time in order to activate access through the combination.
In more secure locations, there are two or more mechanical dial lock, one being accessed with a different combination sequence from that of the other so that in fact two different people having two CA 0221~080 1997-09-09 different numerical combination sequences are required to open the vault.
Night depository boxes are mounted on the outside of financial institutions for the receipt of cash and negotiable instruments, which provide a night depository access door on the outside of the building and a mechanical dial lock door on the inside of the building for staff of the financial institution to gain access into the night depository. The same applies in relation to the egress and the deposit into automatic teller machines (ATM) which are capable of dispensing funds using pin numbers and credit cards and the like to clients.
It is known in the financial industry that there are lS inconsistencies in relation to night deposits, of the amount of money alleged to have been deposited by each depositor, according to their tally slips vis-à-vis the actual funds or total deposits received by the institution. In relation to ATM machines, the alleged amount of money deposited into the ATM machines by staff or courier security staff of the financial institution has discrepancies vis-à-vis the amount of money actually available or withdrawn by the customer.
With mechanical dial lock technology, there is no way to determine who had access to the vault or depository in order to effect a proper audit. It is for this reason that programmable digital locks have come into being. On new installations of vaults, night depositories and ATM machines, programmable digital locks are used rather than mechanical dial lock technology. There are a great many existing old dial lock technology vaults, ATM machines and night depositories which have to be replaced.
The advantage to programmable digital locks (PDL) is that they provide an electronic record of access by each person using the PDL; the time and duration of the access or egress. Each person is provided with their own numerical (password) or pin. The pin is entered CA 0221~080 1997-09-09 into a touch key pad mounted on the outside of the door making electrical connection to a computer which when receiving a match to the pin, records in its memory the pin number and access time and actuates a release mechanism releasing for sliding movement the vault bolt mechanism mounted on the inside of the door thereby permitting access into the vault. A typical programmable digital lock is that known as AUDITCON~
supplied by Mas-Hamilton of Lexington, Kentucky, U.S.A.. By using such PDL, formal audit can be conducted electronically by means known now in the art to determine who has had access and egress into such vault. Those skilled in the art will know that the footprint of the inside case for mechanical rotary dial lock is basically standard for a number of different manufacturers of those types of locks and not all of them use a bolt action for the combination but some also use a rotary gate mechanism which allows access into the lock case of the locking bolt assembly on the vault door.
It is an object of the invention to provide a simple means or interface to substitute the mechanical tumbler vault lock mechanism for a digital vault lock mechanism without the need to replace, re-design or machine the opening door mechanism to accommodate the digital vault lock access mechanism. Conventionally without this invention, it takes between 8 and 12 hours of skilled machinists who are also financially bonded to mechanically substitute a rotary tumbler mechanical vault lock mechanism with a digital vault lock mechanism so that the digital vault lock mechanism can access the opening sequence for the vault.
The invention will now be described by way of example and reference to the accompanying drawings in which:
Figures 1 and lA are outside and inside perspective views of conventional mechanical dial lock assemblies;

Figure 7 is an assembly view of the housing portion with the adaptor plate, according to the invention;
Figure 8 is a rear plan view along section lines VIII-VIII of Figure 4;
Figure g is a perspective of a dial housing modified according to the invention.
Referring to the prior art Figures 1, lA, 3 and 6 and 6A, a vault door is generally shown as (VD) and has a mechanical dial lock assembly (10) mounted on the vault door, with the rotary dial (11) on the outside surface of the door and a dial housing (12) seen in Figure lA, mounted on the inside of the door, with a dial shaft (13) extending through the vault door, most clearly seen in the cross-sectional Figure 3. The housing (12) has its case (14) mounted directory onto the interior surface of the vault door (VD) with a CA 0221~080 1997-09-09 cover plate (15) removably secured to the case (14) so as to complete the housing (12). Within the housing (12), and shown in phantom in Figure 3, is a tumbler assembly (16).
Referring to Figures 6 and 6A, the tumbler assembly (16) consists of a plurality of co-axially spatially disposed tumbler plates or disks but only one is shown in Figure 6 and 6A being tumbler disk (17). Each tumbler disk (17) of the assembly (16) is essentially circular with a single peripheral notch (18) and when all the disks (17) have their respective notches (18) in registration and the dial (11) is counter-rotated, arrow (A) in Figure 6, a cam lever indexing assembly (19) is grasped by the notch shoulder on counter-rotation of the dial (11), laterally pulling a bridge assembly (19) upon which there is secured a bolt connector (22) which makes mechanical connection to a bolt carriage assembly which is generally shown in Figure lA as (23), that assembly carrying bolts which travel to and fro and are activated by the partial rotation of a lever (L) mounted on the front door in the conventional manner so that when the lever (L) is rotated, in the drawings in a counterclockwise direction, travelling bolts with the bolt carriage assembly index out of the surrounding outer walls of the vault door and into the vault door and thereby, the vault door may be swung open in the conventional manner known.
A programmable digital lock unit (PDL), (30) is mounted for rotation within its exterior housing portion (32), the dial (31) having a shaft (33) extending through the exterior housing portion (32) through the vault door (VD), and into the case (14) of the prior art, through the novel adaptor plate assembly (40), according to the invention and rearward to a rearward digital lock internal housing (32') being part of the programmable digital lock unit (30).
Within the outer housing (32), not shown, the prior art CA 0221~080 1997-09-09 programmable digital lock has a built-in computer and logic circuits and there is a multi-track conductive foil (35) electrically connecting the logic of the computer in the exterior housing (32) to an actuator (36) within the internal housing (32'). The prior art programmable digital lock (30) is operated by rotating the dial (31) in one direction which drives a dynamo, (not shown), within the exterior housing (32) to generate electricity and to charge an electronic storage device, for instance, a capacitor whereupon the person wishing to access the vault enters in their pin number onto a digital key pad (36) located on the upper surface of the outer housing (32), as shown in Figure 5. After entering the appropriate pin sequence, a signal is sent by the computer in the exterior housing portion (32) over or through the foil assembly (35) to a relay (37) located in the internal housing (32'). On its activation of the actuator (36) into a nested retracted position, and on further counter-rotation of the dial (31), a latch allows the travel of the bolt connector (22) into the case (14) in the fashion as will be described with reference to the assembly Figure 7 and Figures 8 and 9.
Referring to the assembly Figure 7, 8 and 9, the existing housing (14) of the mechanical dial lock of the prior art is employed but all the internal components including the rotary disk tumblers (17) are removed and discarded, but retaining its sliding lock bolt (20), the existing lock housing (14) yet removing pin (25) to be replaced with longer lever pin (45), (see Figure 7) indexing into the same aperture (25).
The locking bolt (20) is held within the case by a spacer plate (41) which is profiled at (42) to allow the extended lever pin (45) to pass therethrough. The back plate (15) of the prior art locking housing (14) is discarded and replaced with new adaptor plate (44) defining a slot (42') through which the lever pin (45) can extend. As well, the shaft (33) of the dial (31) CA 0221~080 1997-09-09 extends through the apertures (46), and (65) as will be described, to index into the digital lock housing (32').
The adaptor plate (44) provides a fulcrum pin (48') on its exterior rearward face. The pin (48') acts as the fulcrum to an actuator bar (47). The actuator bar (47) defines at its lower extremity an accommodating aperture (48) for the extended lever pin (45) as its fulcrum. There is a second aperture (49) in the actuator (47) and that aperture acts as the effort point and into the second aperture (49) indexes a protruding pin (50) located on a bolt mounting adaptor plate (51), generally formed in the shape of the letter "L" which is provided with two counter-sunk apertures at the foot of the "L" to accommodate flat head machine screw (53) which is threaded into an existing threaded aperture pair located in a travelling bolt unit of the internal housing (32) of the programmable digital lock.
There is a lock mounting plate (60) which has a rectangular notch (61) for accommodating the to and fro travel of the bolt lock mounting plate (60). The bolt lock mounting plate (60) also provides aperture (65) while at the same time, the adaptor plate t44) provides the aperture (46). Those two apertures are in relative registration to permit the passing of the programmable digital lock dial shaft (33) therethrough so that shaft (33) can extend into the rear digital lock housing (32') in the fashion conventionally known for that lock assembly. The actuator (47) has a third inclined, essentially obround, aperture or cam slot (50) to accommodate travel within that cam slot (50) of the extended pin (45) in the fashion, as will now be described. When the dial (31) is counter-rotated, the shaft (33) is also counter-rotated and activates the egress and access of the bolt (54) causing the extended pin (51), which is indexed in aperture (49), to move the actuator bar (47) in a clockwise or counterclockwise direction. The extended lever pin CA 0221~080 1997-09-09 (45) thereby travels up and down slot (50), as shown in the phantom and solid lines of Figure 8 the fixed distance (D) which is the extent of travel of the bolt head (27) of the carriage (20). By judicially altering the length of the slot (50) and the relative centres of the apertures (48) and (49), a greater or lesser throw is achieved so that the mechanical leverage of the distance of travel(d) of the bolt (54) of the programmable digital lock assembly (30) can be adjusted to satisfy the demanded distance of travel (D) for the existing locking bolt (20).
This invention relates to a security lock interface.
More particularly, the invention relates to a mechanical interface adaptor, which when mounted on the interior surface of a vault door, permits the substitution of a conventional mechanical rotary tumbler lock assembly, commonly referred to as a combination lock or conventional mechanical dial lock technology. The dial lock is designed to actuate access into the vault by releasing for movement one or more sliding bolts mounted on the interior vault door.
Generally, the sliding bolts are slid to and fro by a movement on the outside of the door of a bolt actuating lever. The dial lock permits the sliding of the bolt when the dial of the lock is rotated clockwise and counterclockwise to the appropriate sequential numbers on the dial. The mechanical interface adaptor permits the replacement of the mechanical dial lock with a programmable digital lock actuating assembly without the need for tampering or adjusting any of the existing mechanical sliding bolt assemblies.

Referring to the prior art Figures 1, lA, 3 and 6 and 6A, a vault door is generally shown as (VD) and has a mechanical dial lock assembly (10) mounted on the vault door, with the rotary dial (11) on the outside surface of the door and a dial housing (12) seen in Figure lA, mounted on the inside of the door, with a dial shaft (13) extending through the vault door, most clearly seen in the cross-sectional Figure 3. The housing (12) has its case (14) mounted directory onto the interior surface of the vault door (VD) with a CA 0221~080 1997-09-09 cover plate (15) removably secured to the case (14) so as to complete the housing (12). Within the housing (12), and shown in phantom in Figure 3, is a tumbler assembly (16).
Referring to Figures 6 and 6A, the tumbler assembly (16) consists of a plurality of co-axially spatially disposed tumbler plates or disks but only one is shown in Figure 6 and 6A being tumbler disk (17).

A programmable digital lock unit (PDL), (30) is mounted for rotation within its exterior housing portion (32), the dial (31) having a shaft (33) extending through the exterior housing portion (32) through the vault door (VD), and into the case (14) of the prior art, through the novel adaptor plate assembly (40), according to the invention and rearward to a rearward digital lock internal housing (32') being part of the programmable digital lock unit (30).
