This invention relates to automated banking machines. Specifically this invention relates to a locking bolt work apparatus for a secure enclosure of an automated banking machine, and its method of assembly.
Automated banking machines are known in the prior art. Popular automated banking machines often used by consumers are automated teller machines (ATMs). ATMs are increasingly used by consumers to conduct banking transactions. Common banking transactions conducted by consumers at ATMs include deposits, withdrawals, account transfers, and balance inquiries.
Most ATMs include a secure enclosure. The secure enclosure is used to hold currency and other valuable items inside the machine. Deposits made by customers into an ATM are also preferably held within a secure enclosure until they can be removed by authorized personnel. The secure enclosure also preferably houses portions of the mechanisms used for receiving deposits and dispensing currency. The secure enclosure also preferably houses electronic components of the ATM which may be subject to attack by someone attempting to compromise the security of the ATM or the electronic communications network in which it is operated.
Secure enclosures used in automated banking machines are specifically made for the type of machine in which they are used. Such enclosures, unlike most common types of safes or vaults, include multiple openings through the walls of the enclosure. These openings are precisely positioned. Such precise positioning is necessary to cooperate with the components of the ATM outside the enclosure. For example, an opening through the secure enclosure is required to enable a currency dispenser mechanism within the secure enclosure to pass currency notes to a delivery mechanism outside the enclosure that delivers the notes to the customer. Likewise a precise opening is required to pass deposit envelopes and other valuables from the deposit accepting opening and mechanism outside of the secure enclosure to the depository mechanism inside the secure enclosure. Similarly, wiring harnesses and other connectors for the electronic and alarm components within the enclosure extend through enclosure openings which must be accurately positioned to enable connection to other wiring or devices in the ATM that are outside the enclosure.
There are many types of ATMs. ATMs can be configured as lobby units, which are made to be used within the confines of a building. Other ATMs are made for “through the wall” installation which enables a user outside of a building to use the machine. ATMs vary in physical size due to a number of factors. ATMs that provide a wide variety of functions, such as passbook printing, ticket or stamp dispensing, check cashing and other functions must necessarily be physically larger than machines that do not provide such functions. Such multifunction machines generally have secure enclosures that are much larger than machines that have fewer capabilities. ATMs that provide a single function, such as dispensing cash, often require a much smaller secure enclosure.
Secure enclosures for automated banking machines include, in connection with a moveable door, a locking bolt work apparatus. The locking bolt work is generally in a secure, locking condition when the door is closed. When authorized personnel act to open the door of the secure enclosure, such as by inputting a proper combination to a lock, the locking bolt work is moveable to a second unsecured condition. In the second condition of the bolt work the door is enabled to be opened so that components within the secure enclosure may be accessed.
Due to the incentive for burglars to attack ATMs, the bolt work and other locking mechanisms used in connection with the moveable doors of secure enclosures preferably provide a high degree of resistance to attack. However, providing enhanced security also often comes with a high degree of complexity. This increases the cost of the automated banking machine. Complex mechanisms can also make it more difficult for authorized personnel to gain access to the secure enclosure.
Thus there exists a need for a secure enclosure and a method of manufacturing a secure enclosure for an automated banking machine that is more reliable and economical.
There also exists a need for a locking bolt work apparatus for a door of an automated banking machine that provides enhanced security, but which is also economical with less complexity and which can be quickly opened by authorized personnel. There also exists the need for a method of assembling the locking bolt work apparatus to a secure enclosure that can be readily accomplished in a more efficient manner.
It is an object of an exemplary form of the present invention to provide a secure enclosure for an automated banking machine.
It is a further object of an exemplary form of the present invention to provide a secure enclosure for an automated banking machine that is more readily accomplished.
It is a further object of an exemplary form of the present invention to provide a secure enclosure for an automated banking machine that is more accurate and reliable.
It is a further object of an exemplary form of the present invention to provide a secure enclosure for an automated banking machine that provides enhanced security.
It is a further object of an exemplary form of the present invention to provide a secure enclosure for an automated banking machine that includes a more secure bolt work apparatus.
It is a further object of an exemplary form of the present invention to provide a secure enclosure for an automated banking machine that includes a bolt work apparatus that may be more readily installed in the secure enclosure.
Further objects of exemplary forms of the present invention will be made apparent in the following Best Mode for Carrying Out Invention and the appended claims.
The foregoing objects are accomplished in an exemplary embodiment of the present invention by a secure enclosure for an automated banking machine that includes a bolt work apparatus. In the exemplary embodiment of the invention the automated banking machine is an ATM. Precisely positioned openings extend through the secure enclosure. The openings enable cooperation between devices and mechanisms inside and outside of the enclosure, which enables the conducting of banking transactions.
The secure enclosure is a generally rectangular enclosure that includes five panels and a moveable door. The enclosure includes a front panel. The front panel is connected to a hinge side panel and a parallel spaced striker or lock side panel. The striker side panel further includes a plurality of vertically aligned apertures therethrough. The enclosure further includes a top panel and a parallel, spaced bottom panel. An opening to the enclosure extends on a side opposite the front panel when the door is in an open position. Each of the panels preferably includes precisely positioned access openings for cooperating with the components which make up the ATM.
The door has mounted thereon a locking bolt work apparatus or mechanism. The locking bolt work mechanism is moveable responsive to the condition of a lock, between a secure and an open condition. The bolt work mechanism includes a moveable locking bolt with a plurality of locking bolt projections. In the secure condition of the locking bolt the locking bolt projections extend in the apertures in the striker side panel of the enclosure. In the open condition the locking bolt projections are retracted from the apertures enabling movement of the door to the open position.
The locking bolt is moveable in response to an actuating mechanism. The actuating mechanism includes a drive cam. The drive cam is in operative to be secured by the lock and is operative to be moved by a door handle when the lock is in an open condition. The drive cam is connected by a generally vertically extending long link to an idler cam. The drive cam and the idler cam are each rotatably moveable and positioned adjacent to a respective vertical end of the locking bolt. The locking bolt is connected to the drive cam by a generally horizontally extending short link. The locking bolt is also connected to the idler cam by another generally horizontally extending short link.
In the secure condition of the locking bolt, the drive cam and the idler cam are in adjacent abutting position with the locking bolt. In addition, an alignment device is operative to rotatably align the drive cam with the lock to enable locking of the drive cam. The alignment device may act as a stop to prevent further movement of the drive cam in a first rotational direction.
In response to unlocking the lock by authorized personnel, the drive cam of the actuating mechanism is enabled to be rotated. The drive cam can be rotated to cause rotation of the idler cam through the long link. The drive cam and the idler cam can be rotated together in a direction that results in the short links moving the locking bolt in an inward unlocking direction. The locking bolt is enabled to move sufficiently to disengage from the apertures in the striker side panel of the enclosure which enables opening of the door. Thus, the locking bolt work mechanism when arranged with a secure enclosure door enables the drive cam to be rotated in a first direction and a second direction to move the locking bolt relative to the door between an extended door-secured position and a retracted door-open position, respectively.
Referring now to the drawings and particularly to
Door 14 has mounted thereon a locking bolt mechanism 24. Door 14 further includes a dead bolt portion 26. The locking bolt mechanism 24 and the dead bolt portion 26 are operative to secure the door in position closing opening 18.
As shown in
Other openings in the front panel 28 are used in connection with a mechanism that receives deposits from customers. Customers may insert deposits through an opening in a fascia of the ATM, and a mechanism delivers the deposit envelopes through an opening in the front panel 28 to another mechanism within the chest portion. Generally the mechanism places the deposit envelopes in a secure removable container within the enclosure.
The chest portion 12 further includes a hinge side panel 36 and a striker or lock side panel 38. The hinge side and striker side panels extend generally parallel from front panel 28. Striker side panel 38 includes a plurality of vertically aligned locking bolt apertures 46. Locking bolt apertures 46 preferably extend through the striker side panel at a position that is somewhat disposed inwardly from a front surface 48 of the panel which bounds the opening 18. Locking bolt apertures 46 are sized for accepting therein projections on a locking bolt in a manner later explained.
Chest portion 12 further includes a top panel 66. Top panel 66 includes an opening 72 for providing access between the components within the secure enclosure and other components of the ATM of which the enclosure is a part. Opening 72 in panel 66 provides access for electronic cabling which communicates with the components inside the chest. Such cabling may be used to transmit signals that control operation of the cash dispensing and depository mechanisms. In addition, wiring harnesses and other cabling provide connections to alarm devices and other equipment that are housed within the secure enclosure.
Chest portion 12 further includes a bottom panel 76. Bottom panel 76 includes access openings 77 for purposes of providing connections to the items within the secure chest. In addition, bottom panel 76 may include plural foot mounting openings (e.g., four openings). Foot mounting openings can accept adjustable feet 88 as shown in FIG. 1. Adjustable feet 88 may be adjusted vertically for purposes of leveling and positioning the ATM of which the secure enclosure 10 is a part.
Door 14 also has a lock 34 mounted thereto. Lock 34 includes a lock bolt member 35 as shown in FIG. 7. Lock bolt member 35 is a member that is moveable between extended and retracted positions. Lock bolt member 35 extends from the case of lock 34 when the lock 34 is in the closed condition. Lock bolt member 35 is retracted into the case of lock 34 when the lock is in the open condition. The lock is operative to be opened from outside of the door 14.
An example of an arrangement of a chest portion and a door for a secure enclosure of an automated banking machine and the assembly thereof may be found in U.S. Pat. No. 6,089,168, the disclosure of which is incorporated herein by reference in its entirety.
An exemplary embodiment of a locking bolt work apparatus 24 is shown in FIG. 4. The locking bolt work apparatus 24 includes a locking linkage arrangement. A drive cam 40 is connected to an idler cam 50 by a connector (e.g., cam link or lever or long link or L-Link) 52. Further embodiments of cam links 134, 196 are shown in
The drive cam 40 is connected to a locking bolt (e.g., lock bar) 60 by a link (e.g., bolt link or lever or upper short link or S-Link) 54. Similarly, the idler cam 50 is connected to the elongated locking bolt 60 by a link (e.g., bolt link or lever or lower short link or S-Link) 56. The bolt links 54, 56 are generally of the same length. Each of the bolt links 54, 56 may also be used with either the drive cam or the idler cam. The short links, 54, 56 are also generally shorter than the long cam link 52. Further embodiments of bolt links are shown in
The locking bolt 60, which is separately shown in
The studs may be fastened to the door in other fastening arrangements. For example, the studs may comprise shoulder bolts which extend into threaded bosses on the door 14. The shoulder bolts can support the locking bolt 60 and enable the locking bolt to slide in supported relation thereon. Although
The locking bolt 60 also has passages or openings 64 to receive an end portion of the bolt links 54, 56. The end portion may comprise a finger, lip, hook, or tab (e.g., FIGS. 13-15).
The operation of the locking bolt mechanism 24 is now explained with reference to
In the secure extended position of the locking bolt 60 shown in
It should also be noted that in the secure position of the locking bolt 60 shown in
As previously discussed, the locking bolt 60 can be held in the secure position shown in
The retraction of the locking bolt 60 causes the locking bolt projections 68 to move out of the locking apertures 46 in the striker side panel 38. This enables the door 14 to be opened. Of course when it is desired to resecure the door, the door may be again moved to the closed position, such as by moving the drive cam in a clockwise direction. In this position the locking bolt 60 may again be extended such that projections 68 engage in the apertures 46 in the striker side panel, and the lock 34 may be changed such that lock bolt member 35 extends into the cut out 42 in the driving cam. This will again place the locking bolt mechanism 24 in a secured or locked condition.
It will be appreciated by those skilled in the art that the locking bolt mechanism, because it provides multiple places (e.g., projections 68) for engagement with an enclosure side panel, achieves more secure locking of the door in the closed position. In addition, the mounting of the locking bolt 60, as well as the nature of the forces applied to move the locking bolt, enables the locking bolt to be moved easily when the lock has been opened. This enables the locking bolt to be rapidly changed from a secure condition to an open condition by authorized personnel.
A further advantage of the locking bolt mechanism of the exemplary embodiment is that if one or more, or even all, of the bolt links are disconnected with the locking bolt in the extended position, the locking bolt cannot be moved to the retracted position. This is because the locking bolt engages the drive cam and/or the idler cam and is prevented from moving toward the retracted position until the drive cam and idler cams are properly rotated. This reduces vulnerability to a successful attack.
The assembly and arrangement of the locking bolt mechanism 24 will now be further discussed.
A pin or shaft 78 can be used to secure the drive cam 40 to the door 14 and secure the retainer 90 to the drive cam 40. The shaft 78 may extend through the retainer 90 and the drive cam 40 and be fastened to the door 14. The shaft may comprise a screw or bolt. A nut 80 and a washer 82 may also be used in the fastening arrangement.
Another pin or shaft 70 and washers 74 may be used to operatively connect the links 52, 54 to the drive cam 40. The pin 70 may be free to move axially or it may be attached to the cam link 52 or the bolt link 54. The pin 70 may comprise a freely movable dowel pin or bolt. The drive cam and the bolt link and the cam link are rotatable on the shaft.
As shown in more detail in
The retainer 90 can retain or keep the drive bolt link 54 from be removed from an opening 64 in the locking bolt 60. Therefore, the retainer is operative to prevent disengagement of the bolt link and locking bolt. The retainer 90 can also retain or keep the operative connection of the drive cam 40, cam link 52, and bolt link 54.
The keeper 92 can retain or keep the idler bolt link 56 from be removed from an opening 64 in the locking bolt 60. The keeper is operative to prevent disengagement of the bolt link and locking bolt. The keeper 92 can also keep or retain the operative connection of the idler cam 50, cam link 52, and bolt link 56.
A shaft 59 functions similar to shaft 78. A shaft 98 functions similar to shaft 70. The shaft 98 may comprise a freely movable dowel pin. The idler cam and the bolt link and the cam link are rotatable on the shaft 98.
A dowel pin 96 may be used to position and prevent the retainer or keeper 92 from pivoting or rotating relative to the idler cam 50. Of course it should be understood that a tab may be used in place of a dowel pin. For example, a tab similar to retainer tab 94 may be fastened to or integral with the keeper 92 to function to position and/or prevent rotation of the keeper 92. Likewise, the retainer 90 may be positioned with use of a dowel pin instead of the retainer tab 94. Also, a tab or dowel pin may be positioned at a predetermined location along the length of a retainer. It should also be understood that washers may be associated with the shafts and pins.
A retainer may be engaged with a cam (i.e., drive cam or idler cam) by the use of another groove or slot in the cam. The retainer 108 of
A combination of a retainer tab and a cam groove may also be used.
The retainer 152 shown in
The locking bolt work mechanism may be used with different types of automated banking machine doors. For example, an ATM may have a front load door and/or a rear load door. The invention permits the same bolt work to be used with either a front load door or a rear load door. For example, a locking bolt work mechanism of a front load door may be rotated 180 degrees for additional operation with a rear load door.
It should also be understood that the components described herein may have additional shapes. Additionally, the drive cam, idler cam, locking bolt, and links may have portions removed (e.g., cut outs) therefrom to permit reduction of material.
An assembly embodiment of the locking bolt work mechanism will now be described with reference to
The idler cam 50 is positioned relative to the locking bolt 60 on a fastening stud or bolt 59. A washer is positioned between the idler cam and the inner face of the door. A lip of the bolt link 56 is mounted into an opening 64 of the locking bolt 60. A dowel pin 98 is extended through the cam link 52, the bolt link 56, and washers and into an aperture in the idler cam 50. Another dowel pin 96, which is typically shorter than the dowel pin 98, is positioned in another aperture of the idler cam. A retainer or keeper 92 is positioned in abutting relationship with the idler cam 50. An aperture in the retainer 92 being aligned with and receiving the dowel pin 96. The keeper 92 is aligned such that it covers the dowel pin 98. The keeper 92 is loosely fastened to the idler cam 50 with a nut 86.
The drive cam 40 can be appropriately positioned relative to the lock bolt member 35 and the alignment device 44 adjusted to reflect that drive cam position. The fastening nuts 80, 86 can then be firmly tightened to secure the locking bolt work mechanism. Of course it should be understood that the method of assembly described herein is merely an example and that other assembly procedures or steps (and their order) may be used with the disclosed bolt work apparatus of the invention. For example, as previously mentioned, an assembly may include having a cam link intermediate of a cam and a bolt link.
In an exemplary embodiment the bolt work apparatus can be installed to a door using an efficient threaded fastener arrangements (e.g., two threaded bolts or studs and corresponding fastening nuts). Thus, the apparatus can provide for an efficient assembly, both in costs and time.
An alternative exemplary embodiment of a locking bolt work apparatus 200 is shown in FIG. 31.
The bosses 240 can function to locate the locking bolt 220. The wider portion 236 of a key hole 228 is able to slip over a stepped boss head 244. However, the narrower portion 238 of the key hole prevents passage of the head 244 therethrough. Thus, the bosses can be moved (e.g., slipped or slid) into the narrower portion of the key holes to secure the locking bolt in an operating position. For example, the locking bolt can be secured with the boss heads outside of the narrower portion of the key holes, as shown in FIG. 34. The arrangement can eliminate the need of fasteners to secure the locking bolt.
The locking bolt 220 can be arranged to hang from the uppermost (e.g., top) stepped boss. The top boss can be operative to correctly locate (e.g., guide) and align (e.g., position) the locking bolt. In an exemplary form of the apparatus, the top boss alone can support the locking bolt. The other stepped bosses can be used for security only, eliminating the need for machining. For example, the other stepped bosses can be directed to providing securing of the lock bolt 220 via the narrower key hole portions. The locking bolt can be used with little or no machining, especially regarding machining for alignment purposes. In other arrangements plural stepped bosses can be used to support the locking bolt 220.
The locking bolt 220 can also have a powder-coating (e.g., a powder-coat paint) applied thereto. The coating can be operative to reduce friction between mating parts. Thus, the need for (additional) lubrication such as grease can be eliminated. Additionally, the locking bolt 220 can be used for both front and rear load safes.
The drive linkage arrangement includes a drive cam.
The drive cam may comprise a laser cut cam. The connector may comprise a laser cut cam link. The connector may also have substantially flat sides. A flat side can extend from one connector end to the other connector end along a common plane. The cam link may further have a wavy or curving configuration or shape (e.g., a W-shape or a C-shape with oppositely curved ends). The retainer can retain or keep the operative connection of the drive cam 202, the bolt link 204, and the cam link 206. The retainer 208 can comprise a plate.
The drive bolt link 204 and an end (e.g., upper or top portion) of the cam link 206 can be secured to the drive cam 202 by using the drive retainer (or drive plate) 208. The securing arrangement can be absent fasteners. That is, the drive cam, drive bolt link, cam link, and drive retainer connection can be arranged so that no additional fasteners are required. A connector comprising a shaft or pin 210 may be attached to, integral with, or one-piece with the retainer 208. The shaft 210 can protrude through aligned holes in the bolt link 204 and the cam link 206. The shaft 210 can also extend into an opening in the drive cam. The shaft can provide a pivot for the bolt link and the bolt. The shaft 210 connects the drive cam and the bolt link and the cam link. The assembly arrangement can secure the bolt link 204 and cam link 206 intermediate the drive cam 202 and the retainer 208.
A fastener (e.g., a nut) 212 can be used to secure the drive retainer and drive cam. Thus, the fastener 212 can secure the drive linkage arrangement to the door 216. The fastener 212 may be (or include) the same nut that secures a door handle portion 214 to the door 216. The fastener 212 arrangement can provide a pivot for the drive cam and drive retainer.
A bushing 218 can be fastened to the bolt link 204. Alternative arrangements may include providing the bolt link 204 with an integral (or one-piece) bushing end portion. The bushing 218 can be inserted into a hole in the locking bolt 220. The bushing hole in the lock bolt may comprise a laser cut hole or opening. The bushing may be arranged in the bushing hole without being fastened to the lock bolt. The bushing can be retained in the hole by the securement of the drive retainer. However, alternative arrangements may include fastening the bushing to the lock bolt.
The idler linkage arrangement includes an idler cam.
A fastener (e.g., screw or shoulder screw) 232 can be used to secure the idler keeper and idler cam. The fastener 232 can secure the idler linkage arrangement to the door 216. The fastener 232 arrangement can provide a pivot for the idler cam and idler plate.
A bushing 234 can be fastened to the bolt link 224. Alternative arrangements may include providing the bolt link 224 with an integral (or one-piece) bushing end portion. The bushing 234 can be inserted into a hole (e.g., laser cut hole or opening) in the lock bolt 220. The bushing 234 may be arranged in the bushing hole without being fastened to the lock bolt. The bushing 234 can be retained in the hole by the securement of the idler plate. However, alternative arrangements may include fastening the bushing to the lock bolt.
In an exemplary form of the locking bolt work apparatus 200, the bolt links 204, 224 can be identical. Also, the bushings 218, 234 may be identical. Furthermore, the pins 210, 230 may be identical. Of course other arrangements may use dissimilar links, bushings, and pins.
The locking bolt work apparatus 200 allows for the use of fewer fasteners (e.g., screws), fewer or no washers, a laser cut locking bolt, a flat laser cut cam link, laser cut cams, and laser cut holes. Thus, the locking bolt work apparatus 200 can result in a reduced part count, a reduction in (or elimination of) machining, and easier assembly.
The sleeve can have non-tapered ends which correspond to non-tapered portions on the shaft to provide for alignment of the handle relative to the door. That is, the shaft can have a tapered outer section intermediate a first constant outer diameter surface section 266 and a second constant outer diameter surface section 268. Likewise, the sleeve can have a tapered inner surface section intermediate a first constant inner diameter surface section 270 and a second constant inner diameter surface section 272. The first constant outer diameter surface section can match the first constant inner diameter surface section, and the second constant outer diameter surface section can match the second constant inner diameter surface section. Thus, matching surfaces can achieve alignment of the handle.
The sleeve and the shaft may have angled tapers resulting in engagement over the entire length of the tapered surfaces. The tapered surfaces may also have engaging teeth. The sleeve can be secured to the door, such as by welding or expanding. The sleeve can also have a step or ledge 274 to prevent its passage through (i.e., out of) the door hole, as shown in FIG. 35. The sleeve ledge can extend radially and circumferentially. The sleeve ledge may also comprise a circumferential series of separated radial projections. The shaft may be forced into the sleeve to prevent its removal therefrom.
The door handle assembly 250 provides additional security. For example, if the handle is broken off from the door through its shaft, then the remaining portion of the shaft cannot be forced (e.g., pushed) inwardly through the door. Rather, the two tapered surfaces would be pressed tighter together, preventing the shaft from being pushed through the door. Since the handle (e.g., via the handle shaft) cannot be forced through the sleeve, the locking mechanisms inside the safe would not be able to be disengaged. The safe may be that of an automated banking machine.
The door handle assembly 250 may be used in the locking bolt work apparatus 200. The door can correspond to the door 216. The handle shaft 260 may comprise the door handle portion 214. The shaft 260 may have a threaded portion operative to receive a fastener 212 such as a threaded nut.
The door handle assembly 250, with the relationship of the handle and sleeve as discussed herein, can add a new level of security to a safe.
Thus the new secure enclosure for an automated banking machine and method of the exemplary embodiment of the present invention achieves the above stated objectives, eliminates difficulties encountered in the use of prior devices and methods, solves problems, and attains the desirable results described herein.
