Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a security container that may be installed in a place accessible to customers, such as a vending machine, cash drawer or deposit machine. More specifically, the present invention provides one or more additional obstacles to an attacker when an unreasonable force attack is applied, thereby preventing the attack from occurring before 9m or security personnel arrive to stop the attacker. Contains sheet metal containers that allow a person only a limited amount of time to break the container.

B. Prior Art Security containers are well known in the art and range from large vaults to simple lockable tin boxes. The vault is constructed to withstand prolonged attack by professional vault waves, and is therefore very thick and heavy. They are not suitable for vending machines due to weight, volume and price. Prior art simple sheet metal containers, such as car trunks, function primarily to prevent amateur thieves from accessing their contents. However, when a punch or other sharp instrument is used to apply an inward force to the sheet metal receptacle, the sheet metal deforms and the entire locking mechanism pops out of the opening, allowing access to the latch mechanism. Once the lock is removed, it is often a simple matter to use a screwdriver or other tool to rotate the latch mechanism and open the sheet metal container within a few seconds.

It is known in the prior art to provide interengaging elements around the periphery of a door in order to deform the door or sidewall to release the latch and prevent the door from being opened. An example is US Pat. No. 3,819,228. It is also known to provide pins or other engagement elements to prevent removal of the door simply by removing the hinge, as shown in US Pat. No. 3,970,340.

PROBLEM SOLVED BY THE C0 INVENTION None of these prior art techniques are capable of protecting sheet metal containers following destruction or removal of the locking mechanism.

This issue was addressed in 1873 in US Patent No. 14,678.
Although recognized by the No. 2 patentee, a solution for interlocking latches using deformation has not been invented to date. 1 in U.S. Patent No. 146782
An auxiliary bolt, not connected to the lock, is provided so as to pop out and secure the door when the trigger plate on the lock is pressed.

This technique adds significant cost to the container and does not utilize modification of the material from which the container itself is formed.

Means for Solving the D0 Problem It is an object of the present invention to deform the container's sheet metal wall or sheet metal door sufficiently to cause damage to the lock or latch, respectively. This is accomplished by providing interlocking apertures or projections in the latch and latch bolt.

Even if such an interlock results in the locking mechanism being completely destroyed or forcibly removed.

Release of the latch or latch bolt that holds the door closed is prevented.

E. EXAMPLE FIG. 1 shows a sheet metal automatic teller machine (ATM) container embodying the invention. The container is at the top 11,
It has a bottom part 13, a rear wall and two side pieces 17 and 19. The access door 27 is hinged on the front vertical side of the side wall 17 in a conventional manner to attach the access door 27 to close the front of the container. Side wall 19 has a latch assembly 15 shown in detail in the enlarged inset. The entire hook assembly 15 has a hook pin 21 attached to an angle plate 23 for engaging a latch 41 attached to the door shown in FIG. The latch, in addition to the gold pin 21, has an interlock that interlocks with a mating interlock aperture 47 in the latch 41 to hold the latch in the latched position if the sheet metal container is deformed during attack.
A pin 25 is provided.

It has been found advantageous to manufacture the latch from a hardened material that is not easily welded. Therefore, forming apertures or other mating interlocking surfaces in the latch prior to curing provides a strong assembly.

Access door 27 closes side wall 19 when the door is closed.
It has a plurality of tabs 26 that engage the slots 16 making it difficult to pull the door 27 away from the door. Such tabs are well known in the art to prevent doors from opening due to side wall deformation and are cooperative with, but not part of, the present invention.

Referring to FIG. 2, the inside of access door 27 is shown. The outside of the door 27 is a simple flat surface with a key lock to control the latch to open the door. Door 27 is made from sheet metal and has a number of reinforcing sheet metal bands 29 and 31.

As shown in FIG. 2, a hinge 33 is attached to the left vertical side of the door 27. Tab 28 is formed as part of reinforcing sheet metal 29 and is also shown in FIGS. 3, 4, and 5. Tab 28 extends behind the front edge of side wall 17. Tab 28 prevents removal of door 27 by cutting hinge 33 from either the door or the side wall.

At the center of the right side of the door is a latch 41 operated by a locking mechanism 43. The latch 41 is shown in the latched position where the hook 45 engages the hook pin 21 on the side wall of the container. The latch 41 also has an opening 47 that engages the interlock pin 25 only when the container door or side wall is deformed. The lock 43 allows the latch 41 to be rotated approximately 90 degrees counterclockwise to unlatch the door 27. When latch 41 rotates 90 degrees, bolt 49 and latch 51 also move because they are attached to latch 41 by pins 53 and 55, respectively. Bolt 49 should face down on the inside of the door.

It moves through the bracket 60 and the guide plate 57. They hold the bolt 49 inside the door. Bolts 49 supported by plate 57 are attached to the container door jam when the door is closed and the bolts are extended.
hooks behind the front bottom edge of the door to keep it closed.

When the door is closed and bolt 59 is fully extended, pin 61 on bracket 60 is juxtaposed to opening 62 in bolt 49. When the area of the door lock is attacked, the door deforms inward in the vicinity of the lock, allowing the top of the bolt 49 to move inward. Such movement causes the aperture 62 to
, thereby preventing withdrawal of the bolt 49 even if the lock 43 were eventually broken and the latch 41 could otherwise rotate.

Similarly, an opening 5 that engages the side of the door when the door is deformed.
It has 9.

Referring to FIG. 3, latch 51 extends into opening 64. Referring to FIG. The latch 51 has an opening 59 that is engageable with an interlock projection 63 that is part of the top of the door. If pressure is applied to the outside of the top surface of the door by a hammer or other means, the web 65 with the protrusion 63 will engage the latch 51 as it is supported by a member 67 attached to the top of the container as shown in FIG. It transforms towards you. When the web 65 is deformed, the protrusion 63 is inserted into the opening 59 of the latch 51.
and prevents the latch 51 from rotating out of the opening 64 and releasing the top of the door from the latched position.

FIG. 3 more clearly shows the reinforcing sheet metal strip 29 to which the hinge 33 is attached.

Tab 28 extends behind hinge 33 when door 27 is closed to prevent access by removing hinge 33.

FIG. 4 shows a cross-section of the door in the lock position to more clearly show the configuration of the latch 41 and its relationship to the interlock pin 25. As can be seen more clearly from Figure 4, 1
When a hammer or other tool is used to open or break lock 43, the front of the door near lock 43 deforms inwardly, allowing latch 41 to interlock with pin 47. Thereafter, rotation of latch 41 is prevented even if lock 43 is eventually broken.

Referring to FIG. 5, there is shown a cross-sectional view near the bottom of the door taken along line 5--5 of FIG. Bolt 49 has opening 62
which engages the pin 61 when the bolt 49 is angled from the vertical as a result of the front of the door being pushed inward or the area near the lock of the door being pushed inward. pin 6
1 is mounted at a distance from the bottom of the door, the bolt 49 moves inward and engages the pin 61. The rear support 66 is a heavy component such as a transformer or a frame member, and when a force is applied to the outside of the door 27, the blanket 60
resists moving inward. The unusually large forces that may occur when someone attempts to force open door 27 cause blanket 60 to deform toward latch 49. FIG. 5 also shows that there is a tab 26 on the right hand side of the door and another tab 28 near the hinge. Although these engagement tabs are well known in the art and are useful for improving attack resistance to sheet metal containers, they do not form part of this invention.

Referring to FIG. 6, an alternative technique for latch bolt 57 is shown as bolt 67 having a protrusion 69. Referring to FIG. The interlock support bracket 71 is provided with opening lowers 3 and 75, which engage the engagement protrusion 69 to prevent the bolt from being pulled out when the door is deformed from the front or the entire door is pushed inward. prevent. FIG. 7 depicts the same bolt 67 and blanket 71 from the side.

As can be seen in FIG. 7, when a force is applied to door 27 from the outside, blanket 71 deforms and interlocks latch bolt 67 to prevent its removal.

FIG. 8 shows another example in which the bolt has a recess and the interlock support has a protrusion.

It is clear that other deformable materials, such as plastics, may be used in place of the metal in the present invention.

F6 Effects of the Invention By using the present invention, it is possible to improve the attack resistance of the security container.
