Definitions

  • the present invention relates to safes, and more specifically to safes having mechanisms which bring about an additional locking effect in the event of an unauthorized attack being made on a safe, in a bid to remove some of its contents.
  • safes may be used in automated teller machines (ATMs) and typically comprise a welded steel container having a hinged door.
  • re-lockers When such additional locking mechanism is activated, it may cause a spring loaded bolt to fire into a position which will either cause additional blocking, thus preventing the safe door from being opened, or which will prevent the safe locking boltwork mechanism from being unlocked.
  • re-lockers One type of re-locker is a thermal re-locker which is designed to be activated when an attempt is made to break into a safe using thermal tools.
  • the re-locker 10 includes a bolt 12 primed by means of a compressed spring 14 and held in a tubular container 16 fixed, in this instance, by four bolts 18 to a safe door 20.
  • the spring 14 is prevented from firing the bolt 12 by having a retaining string 22 attached to the bolt 12, the other end of the string being anchored at a point 24, so that the string is under tension.
  • the string is routed over two pulley wheels 26 so as to avoid obstacles.
  • the material of the string 22 has thermal properties, such that the string 22 will break when the surrounding air reaches a certain temperature. This string breakage will cause the bolt 12 to fire, thereby locking the safe door 20 by means of the bolt being pushed into a recess 28 in the jamb 30 of the safe door.
  • thermal re-locker Another disadvantage of this known thermal re-locker is that the string can deteriorate, such as by abrasion effects during alarm fitting or maintenance, or through environmental conditions, such as high humidity. This can lead to premature firing of the locking bolt, causing unwanted lock-outs on the safe.
  • a thermal re-locker in accordance with the invention makes use of an actuating member made of a special alloy which exhibit temperature controlled, reversible mechanical memory behaviour known as shape memory effect.
  • shape memory effect By varying the components and actual proportions of an alloy, a shape memory effect alloy can be produced which will abruptly change its crystalline state, and thereby its physical properties such as its shape or stiffness if its temperature is raised above a specified level. Also, an item made of such an alloy may change its shape if its temperature is raised above said specified level. Correspondingly, if the temperature later falls to an appropriate level, the shape memory effect alloy will abruptly regain its original properties.
  • Shape memory effect alloys are known as memory metals.
  • a technical paper "Shape Memory Alloys" by D E Hodgson, M H Wu and R J Biermann, available from Shape Memory Applications Inc., 2380 Owen Street, Santa Clara CA 95054 gives details of the types of alloys used, their composition and the current uses of memory metals.
  • a safe having at least one thermal re-locker which includes a re-locking bolt, characterized in that said bolt is movable between a locking and a non-locking position under the control of an actuating member of memory metal, said bolt being held in its non-locking position when the temperature of said actuating member is below a predetermined value.
  • FIG. 2 an ATM 100 having a safe 102 is shown. Access to the safe 102 is by a hinged door 104. The door 104 is locked by a boltwork mechanism 106. On the inside of the door 104 are fixed several thermal re-lockers 108.
  • a thermal re-locker 108 is shown in its retracted, non-locking position.
  • the re-locker 108 includes a tubular container 110 which is fixed by means of an integral flange 112 to the inside of the safe door 104 by four bolts 114.
  • a re-locking bolt 116 Suitably mounted within the container 110 is a re-locking bolt 116 which has a recess 118 into which one end of the shaft 120 of a plunger 122 is fixed.
  • the shaft 120 passes through a hole in a partition plate 124 which divides the container 110 into first and second tubular portions 126 and 128, the tubular portion 126 serving to accommodate the bolt 116 when in its retracted position.
  • the other end of the shaft 120 is attached to the head 130 of the plunger 122, the head being slidably mounted within the second tubular portion 128.
  • a cap 132 is fixed to and covers the end of the container 110 remote from the re-locking bolt 116.
  • a compressed spring 134 of memory metal is disposed between one side of the head 130 and the cap 132, while a compressed metal spring 136 of non-memory metal is disposed between the other side of the head 130 and the partition plate 124. It will be appreciated that the springs 134, 136 are mounted so as to exert opposing forces on the head 130 and thereby on the bolt 116. As will be explained later, the spring serves as an actuating member for bringing about activation of the re-locking bolt 116.
  • a suitable memory metal for the spring 134 is a nickel-titanium alloy with a composition of 49 atoms of nickel to 51 atoms of titanium.
  • re-locking bolt 116 there is a recess 138 in a jamb 140 associated with the safe door 104. Part of the bolt 116 is pushed into the recess 138 if the re-locker 108 is activated.
  • the memory metal spring 134 gives a soft springing action so that the strength of the compressed spring 136 is greater than the memory metal spring 134.
  • the strength of the spring 136 is sufficient to hold the re-locking bolt 116 in its retracted position in the tubular portion 126, with the free end of the bolt 116 being flush with the edge of the safe door 104 adjacent the jamb 140.
  • the temperature of the spring 134 of one or more of the re-lockers 108 is likely to rise to a sufficiently high temperature (typically around 80°C) to trigger the shape memory effect of the relevant spring 134.
  • the spring 134 would then abruptly become much stiffer, compressing the non-memory metal spring 136 and pushing part of the re-locking bolt 116 into the recess 138 in the jamb 140 thus locking the safe door 104.
  • thermal re-lockers 108 described serve as a highly effective defence to a thermal attack.
  • An alternative arrangement could be such that the re-locking bolt 116 would block the locking boltwork mechanism so that the safe could not be opened. Its compactness could allow it to be randomly positioned at several possible points within the locking boltwork thus presenting even knowledgeable safe attackers extra problems and uncertainty as to which areas to attack.
  • thermal re-locker 108 described above is less labour intensive and time consuming to set up than known thermal string re-lockers.
  • Another advantage is that the memory metal re-locker 108 is less likely to cause a premature lock out than a conventional thermal string re-locker, since the former would not be as vulnerable to abrasion or environmental conditions.
