Device for opening a container

Description

[0001] The present invention relates to a device for opening a container.

[0002] The device of the present invention is particularly suitable for opening security cases and, in the following, will be described with reference to its use in opening such security cases. However, the device of the present invention is not limited to such a use and can be used to open a variety of containers having a base with a lid hinged thereto.

[0003] When collected from or delivered to shops, factories, banks, post offices and the like, cash and similar valuable commodities are often transported in a standard security case. The case includes a base with a hinged lid and is typically formed of a tough plastics material. The lid is lockable to the base by means of an electronic mechanism and often a physical locking mechanism.

[0004] Currently, when such a security case is to be emptied at, for example, a bank or a vehicle used to transport the cash or other valuable commodity, the case is opened by the carrier of the case who has the necessary keys to open the electronic and physical locking mechanisms of the case. The carrier thus has full access to the contents of the case.

[0005] For security reasons, it is desirable that, when the case is to be opened, the carrier of the case does not come into contact with the contents of the case.

[0006] According to the present invention, there is provided a device for opening a container of the type having a base with a lid hinged thereto and means for locking the base to the lid, said device comprising:

first means for receiving the container;

second means for holding at least a part of the container in a predetermined orientation; and

third means for opening the container,

   the arrangement being such that receipt of a container by said first means causes said third means to open the container, the device being characterised in that said first means includes an aperture and a surface positioned beyond the aperture to receive the container for sliding movement thereover, said second means comprising a crossbar for engaging the base of the container to hold it in a predetermined orientation and move therewith, said crossbar extending over at least a part of said surface so as to be substantially perpendicular to the direction in which said container, in use, slides over said surface and being linked by linkage means to said third means, said third means including a cross piece for engaging said lid, said linkage means being operable such that said cross piece is movable between a first position above said crossbar and in which, in use, said container is closed and a second position in which, in use, said container is open.

[0007] A device according to the preamble of the preceding paragraph is known from German Offenlegungsscrift No. 1,497,466 which is concerned primarily with opening of film cassettes where avoidance of exposure to light on opening rather than security is a major concern.

[0008] The device of the present invention enables a container to be opened automatically when it is received by the first means. Thus, the carrier of the container is not involved with the opening of the container and therefore does not have any contact with the contents thereof. The contents of the case may be unloaded automatically by gravity so that there is no need for anyone to come into contact with them.

[0009] By virtue of its position, the second means is able to detect when a container is received by the first means and causes the third means to open the case. The second means moves when a container is received by the first means, movement of the second means causing the third means to open the container. The second means may be physically linked to the third means such that movement of said second means causes said third means to open the container. In this embodiment, physical loading of the container into the device causes the detection of the device and hence causes it to be opened.

[0010] Alternatively, the link between the second means and the third means may be, for example, electronic.

[0011] The first means includes an aperture and a surface, the container, in use, being passed through said aperture and slid over the surface to be received by the first means. Preferably, the device is constructed such that the interior of the container is contained within the device when the container is opened, thereby preventing access to the interior of the container from the aperture. Such a construction further ensures that the carrier of the container does not have any contact with the contents thereof.

[0012] The second means is arranged to hold the base in a predetermined orientation and the third means is arranged to open the lid when a container is received by the first means.

[0013] In greater detail, the second means comprises a crossbar for engaging said base, said crossbar extending above at least a part of said surface substantially perpendicular to the direction in which said case is, in use, slid over said surface and being arranged so as to move substantially in the direction of travel of said container. Preferably, the crossbar is biased to move in a direction substantially opposite the direction of travel of said container. The crossbar may then include a plate for separating said base and said lid.

[0014] The device may further comprise means for unlocking said means for locking the container.

[0015] The device may also further comprise means for securing said container in an open position.

[0016] For a better understanding of the invention, and to show how the same may be carried into effect, reference will now be made, by way of example only, to the accompanying drawings, in which:-

Figure 1 is a schematic side view of a device in accordance with the present invention; and

Figure 2 is a schematic front view of the device of Figure 1.

[0017] Referring to the drawings, device 10 is for automatically opening a security case 11 to facilitate loading and unloading thereof. Such a device may be located in the wall of a safe in, for example, a bank or in the side of a vehicle, so that a security case can be inserted from one side of the wall, and the contents of the case can be accessed from the other side of the wall.

[0018] A standard security case 11 comprises a base 12 and a lid 13 hinged at hinge 13a. A handle (not shown) is included at the end of case 11 opposite hinge 13a. Base 12 and lid 13 are lockable together by means of an electronic locking device and catches adjacent the handle (not shown).

[0019] Device 10 comprises a frame 14 of sufficient rigidity to withstand the forces exerted on it during operation. Supported within frame 14 is an inclined open tray 15 for receiving (and therefore slightly wider than) the security case 10. A crossbar 16 is supported within tray 15 with either end thereof being located in an inclined slot 17 cut into the sides of tray 15 parallel to the base thereof. Crossbar 16 can slide up and down along slots 17, but is urged to the upper end of slots 17 by means of springs 18. Crossbar 16 is of square section to prevent any rotation thereof and includes a plate 19 (see Fig. 2), the purpose of which will be described below.

[0020] Each end of crossbar 16 has attached thereto a linkage arm 20a, 20b. The upper end of each linkage arm is rotatably attached to a pivot member 21a, 21b (not shown) which, in turn, is fixed to a pivot arm 22a, 22b. Connecting the pivot arms 22a, 22b is a pivot cross piece 23. Pivot arms 22a, 22b and pivot cross piece 23 form a pivot cradle. Pivot cross piece 23 rests slightly above crossbar 16 and includes a pair of key pins 24 for engaging the catches on the security case 11.

[0021] It will be appreciated that movement of crossbar 16 down slots 17 will cause the pivot cradle to pivot upwardly about a pivot point 25 by means of the linkage arms 20a, 20b and pivot members 21.

[0022] Device 10 also includes a latching device 26 which is positioned in frame 14 to secure the lid 13 of the case 11 when the case is opened. In addition, a roller bar 27 extends across frame 14, the distance between roller bar 27 and the bottom of tray 15 being slightly greater than the height of a security case.

[0023] In use, case 11 is inserted, handle first, into tray 15 and a force is applied to it in the direction of arrow A. This causes a proximity switch (not shown) to allow an electronic switch to release the electronic locking device of the case in a known manner. In addition, the end of the case having the handle thereon is caused to come into contact with crossbar 16 and pivot cross piece 23, base 12 contacting crossbar 16 and lid 13 contacting pivot cross piece 23.

[0024] Contact with pivot cross piece 23 causes the catches on the case 11 to be disengaged by key pins 24. Contact with the crossbar 16 causes plate 19 to separate base 12 from lid 13 of case 11.

[0025] Further application of force substantially in the direction of arrow A (see Fig. 1) pushes crossbar 16 down slots 17. This causes the pivot cradle to rotate about pivot point 25. Because lid 13 is in engagement with pivot crosspiece 23, lid 13 is opened upwardly away from base 12, rotating about hinge 13a. Base 12 is held on tray 15 by plate 19 of crossbar 16.

[0026] Lid 13 is secured open by latching device 26. The positions of the pivot cradle and the crossbar 16 when the case is fully inserted are indicated by the dotted lines in the drawings. Unloading (or unloading) of the contents of the case can then take place. Preferably, unloading is by means of gravity, the contents of the case dropping into a safe.

[0027] After completion of loading/unloading operations, the case 11 is withdrawn from device 10. This causes lid 13 to be released from latching device 26. Springs 18 then return crossbar 16 to its rest position. This also returns the pivot cradle to its rest position and pushes the case 11 out of tray 15 in a movement opposite to the insertion thereof.

[0028] The roller bar 27 ensures that the lid 13 of the case 11 is fully closed as the case 11 is removed from the device 10, thereby causing the catches on the case to engage. Removal of the case 11 from the device 10 causes the electronic locking device of the case to be locked by an electronic switch in a known manner.

[0029] In this way, the person who inserts the case into the device has no contact with the contents of the case. The case is automatically opened by its insertion into the device, allowing it to be loaded or unloaded more efficiently than if a separate opening operation is needed.
