Abstract

The invention relates to a safety container (1) with a money funnel having an armored door (3) precisely matching the door frame located on the front side. Said door has a bolt actuated by a key (8), which engages with the door frame when the door is closed. The armored door (3) initially carries out a parallel movement perpendicular to the front side (2) when it is opened so as to allow access to a safety chamber (11) for cash boxes being protected by the safety container (1), e.g. by rotating around an axis of rotation (10). The door frame has a fold and the armored door (3) includes a matching lateral border which together make it practically impossible to open the armored door (3) with a chisel.

Description

Security container

The invention relates to a security container for cash cassettes according to the preamble of claims 1 and 3.

Such security containers are used at unmonitored paying agencies, such as at public payphones, at toll booths, at all kinds of vending machines, etc., to hold cash cassettes in order to protect them against vandalism or theft and their contents from unauthorized access.

A security container of the type mentioned is known from DE-A 37 16 245. This security container has a door that is pulled particularly firmly against the housing of the security container with a bolt operated by a key as soon as the bolt is closed

Close is pressed. The door has a simple circumferential fold, which positively dips into the housing in order to prevent the housing wall from being dipped in the door area.

It is also known from FR-A 2 461 799 for security containers to store the door in the door hinges in such a way that the door is flush with the housing when closed and in the open state neither over the inner nor the outer wall of the security container protrudes. The door hinges have a parallelogram linkage necessary for the rotary and sliding movement and are housed within the housing so that the door cannot be opened by drilling out the fishing pin.

US-A 4 729 612 describes a box for unspecified purposes, the opening of which is closed by two door leaves. Each door leaf is suspended from two hinges that slide on rails mounted on the inner side wall of the box. When the box is closed, the door leaves rest on a fold and pull the hinges on the rails forward to a stop point in the box opening. As soon as the door leaves have swung open by 90 °, the door leaves with the hinges can be moved into the box parallel to the side wall of the box. A useful device prevents the hinges from sliding on the rails at different speeds and therefore a door wing wedges when it is pushed in or pulled out.

The electromechanical tools that are easily available today pose new challenges for safety container designers. The known security containers have points of attack for tools of this type which enable the security container to be opened violently in a short time, the most important weak point being the door rebate.

The invention has for its object to provide an inexpensive security container that does not offer the known tools a starting point for quick, unauthorized opening. According to the invention, this object is achieved by the features specified in the characterizing part of claims 1 and 3. Advantageous embodiments of the invention result from the dependent claims.

An exemplary embodiment of the invention is shown in the drawings and is described in more detail below.

FIG. 1 shows a view of a security container,

FIG. 2 the security container with the reinforced door,

FIG. 3 shows a section through the security container,

4 shows the extended armored door in section, FIG. 5 shows the armored door in the pivoted state,

6 shows a door hinge on a slide rail and

Figure 7 shows an anchor.

In FIG. 1, 1 means a security container, 2 a front side with an armored door 3, 4 a cover for a key opening, 5 an opening of a money funnel 6 of the security container 1 and 7 an imaginary plane which is oriented perpendicular to the armored door 3 and the security container 1 transversely cuts through. The security container 1 has, for example, the shape of a cuboid or cube. However, depending on the location of the security container 1, other, more complicated forms can also be used. The security container 1 is part of a vending machine (not shown here) of the type mentioned at the outset and protects a cash cassette (not shown here) and its contents. Such cash boxes are e.g. described in DE 37 16 781 C2 and in DE 38 16 016 C2. The cash cassettes have an entry opening for coins or banknotes, which automatically closes when the cash cassette is removed from the security container 1. Because of the great weight of the full cash cassettes, they are not armored themselves, so that they have to be enclosed in the security container 1 at unmonitored places where such vending machines are installed in order to prevent the cash cassette from being broken open quickly.

Preferably, the opening 5 is located in the upper housing wall of the security container 1 as the mouth of the narrow cash funnel 6, which is shown in dashed lines in the drawing in FIG. 1 and ends through the housing wall above the inlet opening of the cash cassette. Coins or banknotes, which are accepted as the equivalent for a service of the vending machine, accumulate in the cash cassette, the coins or banknotes first falling or sliding through the narrow opening 5 of the cash funnel 6 and then through the entry opening of the cash cassette. The armored door 3 is shown in the closed and locked state. To open the armored door 3, the access to the lock of the armored door 3 protected with the cover 4 must be exposed. A cover 4 that can be used for this is described in the German utility model application DE 297 15 732.9 dated 2.07.1997. This cover 4 is a plug inserted into the keyhole, which is anchored in the keyhole with a rotational movement.

To remove the cash cassette, the armored door 3 of the security container 1 must be opened. FIG. 2 shows the first phase of opening the armored door 3. With a tool, a person entrusted with this task first removed the cover 4 (FIG. 1) from the keyhole and opens the locking of the armored door 3 with a key 8. In one embodiment the armored door 3 opens in two movement phases, a parallel movement and a rotary movement. First, the armored door 3 is shifted in a straight line and parallel to the front 2 towards the front by pulling on the key 8 in the keyhole. At least one door hinge 9 designed accordingly and described below enables this parallel displacement. As soon as the armored door 3 is sufficiently removed from the security container 1 by this straight-line parallel displacement, the rotary movement takes place, the armored door 3 advantageously being pivoted about an axis of rotation 10 of the door hinge 9 such that the armored door 3 enables access to a security room 11 with the cash cassette. For example, the angle of rotation is at least 90 °. In one embodiment variant, the door hinge 9 is designed such that the armored door 3 is displaced to the side in a semicircular arc parallel to the front side 2 during opening during the entire movement phase and in this way enables access to the security room 11.

FIG. 3 shows a section through the security container 1 at level 7 (FIG. 1), which shows the security container 1 with the closed and locked armored door 3. The walls of the security container 1 are reinforced on the front side 2 in the area of the armored door 3 and form a door frame 12 with a door rebate 13 running around the opening to the security room 11. The door frame 12 preferably has a circular shape or, as seen from the front side 2 shown in Figure 2, the shape of a rectangle with rounded corners. The cash cassette 14 is accommodated in the security room 11 and is inserted in a guide sleeve 15 arranged in the security room.

In the embodiment shown in FIG. 3, the door frame 12 has the door rebate 13 all around, which is formed from a chamfer 16, a groove 17 and a frame surface 18. The chamfer 16 extends the outer lateral boundary of the door frame 12 against the front side 2. The frame surface 18 lies in a plane parallel to the front side 2, the frame surface 18 being arranged behind the front side 2 at least by the thickness of the door leaf of the armored door 3. The groove 17 is embedded in the frame surface 18 and opens against the armored door 3 or front side 2. The edge of the armored door 3 is that Door rebate 13 adapted, ie a projection over the inside of the door leaf of the armored door 3, a spring 19 engages in the groove 17, while lateral edge surfaces 20 of the armored door 3 nestle flat against the chamfer 16. For manufacturing reasons, the spring 19 can also only partially engage in the groove 17 over the circumference of the opening of the door frame 12 or the spring 19 and the groove 17 are replaced by appropriately placed bolts 43 (FIG. 6) and pin holes 44 (FIG. 6). In another embodiment, not shown here, the arrangement of the groove 17 and the spring 17 is interchanged, ie the armored door 3 has on the inside all around a groove which opens against the security space 11 and into which a spring of the door rebate 13 engages. Because of the engagement of the spring 19 in the groove 17, the security container 1 has an advantageously high resistance to deformation of the security container 1 in the door area.

A locking device with a lock 21 is arranged on the inside of the armored door 3. A keyhole 22 leads the inserted key 8 (FIG. 2) to the lock 21 through the door leaf. The key 8 actuates bolts 23 and 23 'arranged on the inside of the armored door 3, so that at least two bolts 23, 23' are guided through guides 24 Guided inside simultaneously engage in two opposite latch supports 25 in the door frame 12 and anchor the armored door 3. In the drawing in FIG. 3, the guide 24 and the latch support 25 are shown only for the one latch 23. When closing, the bolts 23, 23 'pull the boundary surfaces 20 and the spring 19 into the door rebate 13, so that the boundary surfaces 20 lie flat all around on the chamfer 16, so that the outside of the armored door 3 is practically flush with the closed state Front 2 is and the outside of the armored door 3 fits all around in the door opening.

For a particularly safe design of the security container 1, the armored door 3 is drawn through the bolts 23, 23 'into the funnel of the door frame 12 formed by the chamfer 16 in the closed state, so that the lateral boundary surface 20 lies all around on the chamfer 16. For this purpose, the bolts 23 and 23 'have a high strength and are made, for example, from the material CREUSABRO 4000 (Creusot FR), which has a strength four times that of normal structural steel (SO 7).

So that the door gap can be kept as small as possible, the chamfer 16 of the door rebate 13 and the side edge surface 20 of the armored door 3 are milled with great care, the side edge surface 20 having an angle of inclination β, measured from the perpendicular to the front side 2, which is at most the same or is smaller than the angle of inclination α. the bevel 16. The angle of inclination α of the

Fasε 16 is selected for example from the range of 5 to 25 degrees. The angle of inclination β of the lateral boundary surface 20 is at most 5 angular degrees smaller than the angle of inclination α of the bevel 16. For example, the chamfer 16 has the angle of inclination 15 ° and the lateral boundary surface 20 has the angle of inclination 14 °. This design has the advantage that the the door gap formed by the boundary surfaces 20 and the chamfer 16 is extremely small and does not form a point of attack for prying open the armored door 3.

The armored door 3 is connected to the rotatable part of the door hinge 9 by means of an arm 26. The non-rotatable part of the door hinge 9 sits on a support 27, which in turn e.g. is connected to a sliding element 29 via an intermediate piece 28. The sliding element 29 slides when the armored door 3 is opened or closed on a slide rail 30 fastened in the security room 11. The carrier 27, the intermediate piece 28 and the sliding element 29 form a sliding arm 31. The heavy load of the armored door 3 creates a one-sided load on the sliding element 29 and places high demands on the sliding element 29 in order to ensure smooth sliding on the sliding rail 30 for a long time. These requirements are met, for example, by a ball bearing linear guide from INA Wälzlager Scheffler KG in Homburg / Saar DE (type KWE1S Wl VO RRF / 117).

In many cases, the cash cassettes 14 themselves have sensors that provide information about e.g. collect the fill level of the cash cassette 14, the position of the closure of the inlet opening, the presence and the identification of the cash cassette 14, etc. Power supply and routing of information signals from the sensors is carried out by means of a plug 32 which engages in the contact coupling 33. A cable harness 34 (e.g. a multi-core flat cable) routes this information and other information coming from the security room 11 through a very narrow gap from the security container 1 to the vending machine. When inserting the cash cassette 14, the guide sleeve 15 guides it so precisely that the plug 32, which is arranged, for example, on the rear wall of the cash cassette 14, is inserted precisely into the contact coupling 33 which is arranged in the depth of the guide sleeve 15 when the cash cassette 14 is in its position Working position is.

FIG. 4 shows a detail from FIG. 3. After unlocking the armored door 3, it has been drawn straight and parallel to the front surface 2 in the direction of an arrow 35 from the door rebate 13 of the door frame 12. The slide arm 31 has slid on the slide rail 30 up to a front boundary surface 36, so that the armored door 3 can now be pivoted freely about the axis of rotation 10 (FIG. 2) without the edge surface 20 striking the door frame 12.

5, the armored door 3 is pivoted counterclockwise (arrow 37) by at least 90 °. The security room 11 (FIG. 3) is freely accessible, but in particular the part of the security room 11 occupied by the guide sleeve 15 (FIG. 3) and the cash cassette 14 (FIG. 3), one from the direction of the guide sleeve 15 to the slide arm 31, with the side wall omitted 38 of the guide sleeve 15 side view is shown in Figure 6. The sliding arm 31 at the front boundary 36 (FIG. 4) carries the door hinge 9 and the armored door 3, which can be pivoted about the axis of rotation 10 and is spaced apart from the axis of rotation 10 by the arm 26. The arm 31 is closed when the armored door 3 is closed Security room 11 to a sensor 39 (e.g. inductive proximity switch, light barrier or a mechanically operated switch, such as

Microswitch, reed switch, etc.). As soon as the sliding arm 31 with the armored door 3 has been retracted to such an extent that the armored door 3 can be locked with the bolts 23 and 23 '(FIG. 3), the sensor 39 changes its information signal which is emitted to a line 40 as soon as the rear end 31' of the Slide arm 31 is in front of the sensor 39. The position of the end 31 'is shown in dashed lines in FIG. The output of the sensor 39 is by means of the line 40, which is part of the

Cable harness 34 (Figure 3) forms connected to the vending machine. In another embodiment, at least one further sensor 41 is arranged in the door frame 12 in the area of the latch support 25 (FIG. 3). The sensor 41 checks whether at least one of the bolts 23, 23 'has moved into the bolt support 25 (FIG. 3), i.e. whether the armored door 3 is properly closed or not. The output signal of the sensor 41 corresponding to the position of the latch 23, 23 'is transmitted via wires 42 of the

Delivered harness 34 to the vending machine.

The information such as “armored door 3 not properly closed”, “none, a closed or a full cash box 14 (FIG. 3)” advantageously prevents the vending machine from working, so that it does not provide any service without being able to retain the corresponding monetary value .

In the embodiment according to the drawing in FIG. 6, the armored door 3 has a simple fit in the door rebate 13 and on the inside all around in the area of the frame surface 18 the bolt 43 projecting vertically from the door leaf. When the armored door 3 is closed, the bolts 43 move into the pin holes 44 in a frame part 12 'of the door frame 12 (FIG. 3) and guide the armored door 3 so precisely into the door rebate 13 that the door gap can be kept below one tenth of a millimeter. The retraction of the bolts 43 is facilitated by a conical shape of the bolt end 45. The anchoring of the closed armored door 3 by means of the bolts 43 in the door frame 12 has the advantage that it is practically impossible to deform the security container 1. The pin holes 44 have an air duct 46 in order to allow the air enclosed by the bolts 43 to escape when the bolts 43 are retracted or to prevent a vacuum from forming when the bolts 43 are extended.

The frame part 12 'forms a threshold at the entrance to the security room 11. So that the full and therefore heavy cash cassette 14 (FIG. 3) can be easily replaced, the bottom of the guide sleeve 15 guides the cash cassette 14 when it is removed via this threshold.

In the embodiment according to FIG. 4, the armored door 3 has only the boundary surfaces 20 adapted to the chamfer 16 but no spring 19 (FIG. 3). The security against the deformation of the

Security container 1 is only guaranteed here by a reinforced door frame 12, 12 '(FIG. 6), which, however, significantly increases the total weight of the security container 1.

Back to figure 3! The security container 1 and the armored door 3 are made entirely of high manganese steel, which due to its toughness cannot be processed with normal tools. Should the If key 8 (FIG. 2) is lost or broken off in lock 21, the cash cassette and its contents remain enclosed in security container 1. A hidden emergency entry into the security room 11 is provided so that the operator of the vending machine can replace the lock 21. The

Emergency entry is only accessible after partial disassembly of the vending machine. The emergency entry allows the release of an access guard with the help of special tools, which gives access to the security room 11 and allows the bolts 23, 23 'to be opened without actuating the lock 21 when the armored door 3 is closed. This is a smaller and therefore lighter version

Armored door 3 is not connected to the security container 1, i.e. in this embodiment the hinges 9, slide rail 30 and slide arm 31 shown in the drawing of FIG. 3 are not present. The unlocked armored door 3 can be lifted out with the key 8 (FIG. 2) and removed entirely. When closing the armored door 3 is reinserted in the door rebate 13 and with the

Key 8, the bolts 23, 23 'inserted into the bolt supports 25.

In an embodiment according to FIG. 7, the armored door 3 has no handles which offer a point of attack for a violent opening. The anchoring of the key 8 in the keyhole 22 is reinforced, for example, by a fork-shaped tab 47. When unlocking, the bolt 23 driven by the mechanism of the lock 21 and running in the guide 24 with the tab 47 fastened thereon moves laterally into the keyhole 22 in the direction of an arrow 48. The tab 47 engages in an anchoring groove 50 running around the key land 49 in such a way that the key 8 is prevented from being pulled out. To open the security room 11 (FIG. 3), the key 8 is inserted into the keyhole 22 and the armored door 3 is unlocked, the key 8 being anchored in the keyhole 22 such that the armored door 3 is moved out of the door fold 13 with the handle of the key 8 can. As soon as the bolts 23, 23 '(FIG. 3) lock the armored door 3 and the tab 47 moves in the direction of the arrow 48, the key 8 is anchored in the keyhole 22 again so that the key 8 can be removed again. After inserting the cover 4 (FIG. 1) into the keyhole 22, the outer surface of the armored door 3 has the advantage that it is largely smooth and does not offer any points of attack that enable the armored door 3 to be opened violently.
