Description

The invention relates to a security cabinet, in particular a vault of rectangular parallelepiped shape, comprising a housing with a base, a ceiling, a rear wall connecting the base and the ceiling, as well as two side walls connecting the base and the ceiling and adjoining the rear wall, and a frame arranged opposite the rear wall, with a door arranged in the frame so as to be pivotable about a pivot axis and closing an opening defined by the frame, wherein the door has a front plate on which a locking box is arranged on the inside.Security cabinets of the generic type are used as intended for secure storage of confidential and secret documents, documents, data carriers and the like, and also for storage of valuables, such as money, ornaments and the like. Such security cabinets generally have an access opening which can be closed by means of a single-leaf or also two-leaf door. Preferably, the security cabinets are cuboidal in design and of high weight in order to make unauthorized removal of the cabinet more difficult as possible.As a rule, such safety cabinets are provided for stationary use, but mobile applications are also used. Stationary located safety cabinets can be set up as free-standing devices. In addition, they can also be connected to masonry, foundations and the like of buildings, buildings or the like in order to largely prevent unauthorized removal of the security cabinet.Housings of such safety cabinets are usually formed from metal panels which have a high resistance to corrosion and mechanical influences. Additional reinforcement measures may be provided. The metal panels are generally welded to one another. Due to the design of the safety cabinets from metal panels, in particular from steel, the safety cabinets are designed with a high weight.A generic security cabinet is disclosed, for example, in DE 101 21 016 C2. This security cabinet consists of a housing which has a floor, a ceiling and two side walls arranged between the ceiling and the floor, and also a rear wall and at least one door. The door closes an opening and is clearly articulated on the housing in the region of a side wall.For stability reasons, the opening has a frame which is connected to the side walls, the floor and the ceiling or is formed integrally therewith. In the frame, a device for the pivotable arrangement of the door is provided. This device generally consists of two coaxially opposite bores in horizontally oriented elements of the frame which serve to receive corresponding pins. The pins are attached to the door.When such a safety cabinet is formed from metal panels which are welded to one another, the problem arises, in particular in the region of the combination of frame and door, that when the door is standing up, this represents a risk of injury when it is in contact with a body part, for example head, arm or leg. The metal panels are generally deburred in the edge region and rounded in their longitudinal direction, but more or less sharp-edged corner regions are nevertheless located here in the transition of the edges of the door, which corner regions can lead to painful injuries when in contact with the body of a person. If such a security cabinet is additionally integrated into a masonry at an ergonomic height, a person erecting from a bent posture can abut with the head or a shoulder against an open door of the security cabinet and damage itself.Furthermore, in the safety cabinets of the prior art described here, a possible relative movability of the door with respect to the frame in the closed state also results. This movability is already caused due to the pivot axis and the material tolerances, since the door is basically arranged in the frame in such a way that the door adjoins the frame flush towards the outside and a gap space between the frame and the door should be as small as possible when the door is closed, in order to make the attachment of break-in tools, for example a cow's foot, more difficult or prevented as much as possible. Here, relative movements between the housing and the door are also entirely to be observed, which allow a relative movement of the door with respect to the frame even when the door is locked.Proceeding from this prior art, the object of the invention is to avoid the above disadvantages and in particular to reduce the risk of injury to persons when the door is open and at the same time to reduce or prevent relative movability of the door with respect to the frame when the door is locked.The solution of this task provides, in a generic security cabinet, that the door has a protective element at least in a corner region of the front panel, which protective element covers at least transition regions of narrow sides of the front panel running at an angle to one another, preferably at an angle of 90°.These protective elements thus cover the narrow sides of the front plate at least in the corner regions. A corner region is to be understood as the region which is equally associated with the narrow sides. The protective elements serve on the one hand to reduce the risk of injury in the event of unintentional contact of a body part with the covered region of the door. At the same time, the protective elements can be designed in such a way that, owing to their material thickness, they fill a gap region between the outer edge of the door and the frame when the door is closed in such a way that frictional contact is established between the door and the frame, which at least restricts the relative movement of the door with respect to the frame when the door is locked.According to a further feature of the invention, it is provided that the protective elements consist of a plate and strips extending perpendicularly thereto along two edges of the plate. Accordingly, the protecting members are formed of the strips disposed on the narrow sides of the front panel. Furthermore, the strips are connected to one another via the plate, so that the assembly of the protective elements is substantially simplified by forming a one-piece protective element with an L-shaped cross section from the strips and the plate.Preferably, the strips have elements angled at right angles at free edges, so that the panel, the strips and the elements form a U-shaped receptacle in cross section for a corner region of the front panel. In this embodiment, protective elements are provided which can be easily slid over the front panel of the door in the region of a corner region. The U-shaped receptacle has dimensions which are substantially formed with a material thickness of the front plate in the region for receiving the protective element, so that the protective element can be connected to the front plate in a force-fit manner. For this purpose, a frictional force is provided between the protective element and the front plate.Preferably, the elements angled at right angles form a covering element of identical area to the plate. In this embodiment, the protective element can be slid onto the corner region of the front plate without observing a specific orientation. Assembly errors are avoided. Furthermore, this configuration has the advantage that, as a result of a greater surface contact between inner surfaces of the cover element and the plate with the outer surfaces of the front plate, a greater frictional force is provided overall. A larger area of the front plate is also covered by the protective element.According to a further feature of the invention, it is provided that the plate is formed as a right triangle or as an isosceles triangle.The protective element is preferably formed from a compressible plastic which, on the one hand, has an impact-damping effect and, on the other hand, is compressible in the closed position on contact with the frame, so that friction locking is built up between the front plate and the frame.According to a further feature of the invention, the protective element is fixed in a clamping manner on the front plate. Such a protective element can be replaced in a simple manner, for example, in the event of damage. The same applies also in a case in which such a protective element is also intended to develop an aesthetic effect, wherein the user of a corresponding security cabinet has the possibility of adapting the aesthetic effect to his subjective design requirements by replacing protective elements.In order to improve the connection between the protective element and the front plate, it can be provided according to a further feature that the protective element is glued to the front plate. Various adhesives are suitable for the bonding. For example, it can also be provided that a heat-activatable adhesive, a so-called thermoplastic, is used, so that after the protective element has been mounted on the plate, the adhesive can be activated by heating the protective element.Finally, according to a further feature of the invention, it is provided that protective elements are arranged at the corner regions of the front plate, which corner regions are arranged facing away from the pivot axis. It is precisely these regions that are primarily considered for a contact, which causes an injury, between a body part and an open door of the security cabinet.Further features and advantages of the invention will become apparent from the following description of the associated drawings. In the drawing, the following are shown: FIG. 1 shows a security cabinet according to the invention in a perspective front view; FIG. 2 shows a door for a security cabinet according to FIG. 1 in a perspective rear view; FIG. 3 shows a first embodiment of a protective element in a perspective view, shown partially in section; FIG. 4 shows a second embodiment of a protective element in a perspective view, shown partially in section; FIG. 5 shows the protective element according to FIG. 3 in a front view; FIG. 6 shows the protective element according to FIG. 4 in a side view shown in section, and FIG. 7 shows a third embodiment of a protective element in a perspective view, as it is also arranged on the door according to FIG. 2.FIG. 1 shows a security cabinet according to the invention, which is designed as safe 10. The safe 10 consists of a housing 12 which is substantially cuboidal. The housing 12 has a base 14, a ceiling 16, and two side walls 18, 20 arranged between the ceiling 16 and the base 14 at right angles thereto, and a rear wall 22, which surround and define an interior space. Furthermore, a door 24 is provided on the housing 12 and closes an opening 26 of the safe. The door 24 is pivotably articulated to a frame 23 which terminates with the ceiling 16, the floor 14 and the two side walls 18, 20, wherein the frame 23 is welded, for example, to the aforementioned structural elements of the safe 10 or consists of sections of the corresponding structural elements.A locking mechanism 21 is arranged in the door 24, which can be actuated by means of a key, not shown in detail. The closure mechanism 21 actuates a closure mechanism with which the door 24 can be locked in the closed position. The locking mechanism is arranged in a lockbox 11 (FIG. 2 ).It can be seen in FIG. 2 that the lockbox 11 forms the door 24 with a front plate 13. The front plate 13 can also be of double-layered construction, as is illustrated in FIG. 2.FIG. 2 shows the door 24 of the safe 10 according to FIG. 1 in a perspective view seen from the interior side of the safe 10. The front plate 13 is formed from two metal layers connected to one another, wherein the lockbox 11 has a shorter length and a lower height compared to the front plate 13, such that the front plate 13 protrudes beyond the outer dimensions of the lockbox 11.Both the locking mechanism 21 and also elements controlling the locking mechanism are arranged in the lock box 11. It can be seen that two catches 15 protrude from the catch box 11 and are driven movably in their axial direction by the locking mechanism 21. The same applies to a basket latch 17 which projects upwards out of the latch box 11 and which can be moved by means of the locking mechanism 21 in a direction parallel to the direction of movement of the latches 15.On the sides of the lock box 11 opposite the bolts 15, ends of pins of a pivot axis 19 protruding upward or downward are formed. These ends of the studs are arranged, namely welded, by means of blocks 25 on the inside of the front plate 13. The pins of the pivot axis 19 engage in apertures, not shown in detail, in the frame 23, so that the door 24 can be pivoted about the pivot axis 19 relative to the housing 12 via these pins.FIGS. 1 and 2 show protective elements 26 which are arranged at least in a corner region (FIG. 2 ) of the front plate 13. The protective elements 26 cover narrow sides 27 of the front plate 13 running at an angle of 90°.Two embodiments of the protection elements 26 are shown in Figs. 3 to 6, wherein Figs. 3 and 5 show a first embodiment and Figs. 4 and 6 show a second embodiment of a protection element 26.The first embodiment of the protective element 26 according to FIGS. 3 and 5 consists of two plates 28 which are arranged parallel and spaced apart from one another and are of identical surface design, and two strips 29 which extend at right angles to the plates 28 and are formed with inner surfaces 30 for bearing against the narrow sides 27 of the front plate 13. The two plates 28 are connected to one another via the strips 29, wherein the protective element 26 is formed in one piece.The two plates are each triangular, namely formed as isosceles triangles, the two strips 29 being arranged running along the two legs of the plates 28 of equal length. The plates 28 have hypotenuses 31 as an isosceles triangle, which are not connected via a strip 29, so that an opening 32 is formed in this region, which serves to cover the protective element 26 via the front plate 13 in the region of a narrow side 27 running through the two mutually at right angles.The protective element 26 is formed in one piece and consists of a compressible plastic.A second embodiment of a protective element 26 is shown in FIGS. 4 and 6. This embodiment of the protective element 26 differs from the embodiment according to FIGS. 3 and 5 in that a plate 28 is formed as an isosceles triangle, while a part-area holding element 33 is arranged opposite the plate 28, which element extends along the equal-length legs of the protective element 26 parallel to the plate 28 over the entire length of the legs.Both embodiments of the protective element 26 according to FIGS. 3 to 6 can be easily plugged onto the front plate 13. In this regard, the protective elements 26 have a certain elastic deformability, so that, for example, the opening 32 can be formed slightly smaller than the material thickness of the front plate 13. The correct fit of the protective element 26 can be supplemented by an adhesion of the protective element 26 to the front plate 13, wherein it has proven advantageous to use a thermoplastic adhesive for this adhesion, which can be activated by supplying heat. In this case, the protective element 26 can be easily slid onto the front plate 13 and then the thermoplastic adhesive can be activated by the action of heat, so that the protective element 26 is fixed to the front plate 13.Finally, Fig. 7 shows a third embodiment of a protective element 26, in this embodiment a plate 28 is formed by two side elements 34 connected to the strips 29 which extend at right angles to the strips 29 and are interrupted by a recess 35. The recess 35 extends with its longitudinal axis parallel to a bisector of the substantially triangular protective element and is open on one side, while one end of the recess 25 has a semicircular course in the strip 29.The side elements 34 have a free edge 36 which is aligned running parallel to the edge region of the transition of the strips 29 into the side elements 34. These free edges 36 pass rounded into the side regions of the recess 35.A plate 28 disposed opposite the side elements 34 is triangular. Rather, further additions and features are possible without departing from the scope of protection of the invention.For example, two protective elements 26 arranged on the front plate 13 in corner regions can be connected via a strip-shaped cover extending over an entire narrow side 27. This cover can also be partially supported as a U-shaped element on the front plate 13. In the same way, an L-shaped element can also be provided here, which element is arranged, for example, resting only on the outer surface of the front plate 13 or only on the inner side of the front plate 13. It is also possible for the protective element 26 to extend over all edges of the door 24, with the exception of one in the region of the articulation of the door 24 on the frame 23.Reference numerals denote reference numerals10 Safe 11 Lock box 12 Housing 13 Front plate 15 Lock 16 Ceiling 17 Basket lock 18 Side wall 19 Pivot axis 20 Side wall 21 Closure mechanism 22 Rear wall 23 Frame 24 Door 25 Block 26 Protective element 27 Narrow side 28 Plate 29 Strip 30 Inner surface 31 Hypotenuse 32 Opening 33 Holding element 34 Side element 35 Recess 36 EdgeReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
