Definitions

  • the invention relates to a device for monitoring the closed position of a pivotable closure, a pivoting door or flap of a secured space or container, in particular an armored cabinet door, with an actuating element which can be moved by the pivoting of the closure and a switching element acted upon by this actuating element.
  • a second possibility that has become known consists in displaying the angular position, which is encapsulated in the hinge of the door, as described in WO 79/01028.
  • the actuator is a deflectable or flexible pull element transverse to its longitudinal extension, that one end of this pull element at a distance from the axis of the pivot bearing of the door on a stationary part in the region of the pivot bearing or on the hinge side of the door is attached that the pulling element can be deflected by the pivoting of the door or the like in turn in the pivoting direction of the door (in the same way also of another lock), its end opposite the fastening end being movable relative to the door or the like, and that door-side end in the closed position of the door or the like acts on a switch, a lock or the like and already releases an acute angle in its opening direction when pivoting the door or the like.
  • Such an arrangement can be easily installed - even on an existing lock or door, that is to say later, and is largely secured against manipulation due to the simplicity of the construction, but can also be accommodated and fastened with sufficient protection.
  • the mechanism is very simple and therefore little or not susceptible to malfunction, since it can be exploited that two pivoting parts, which are arranged at a distance from one another and have pivoting parts, one of which is carried by the pivoting of the other, have different, distant paths at their ends or describe curves so that these path differences when pivoting the closure can be used to actuate a switch, a lock or another signal or actuator.
  • the pulling element is guided inside the door or the like and / or a lock housing and protrudes therefrom on the narrow side of the door or the like or the lock housing near the hinge or hinge and is closed on the wall of the door or the like Housing, space or container or attached to the door frame or the like, for example welded.
  • the pivot center lies in the hinge of this door, while the pulling element is pivoted and / or bent relative to an area offset from it at a distance from it, so that its free end is more and more compared to its original position relative to the door want to stay towards their hinge. If the door is pivoted in the closed position, however, this end or the end region is pushed away from the hinge relative to the inside of the door or retracted into an initial position and the switching element can thereby a switch or a mechanical lock.
  • tension element in a manner to be described in several exemplary embodiments expediently be a tensile and compressive, transverse to its longitudinal extent - for example in any cross-sectional area - deflectable or flexible rod-shaped part, i.e. a kind of rod or stable cable can, which part is still referred to as "tension element" in the following.
  • the passage of the pulling element through the narrow side of the door and the outside thereof can be arranged behind at least one fold or the passage through the lock housing behind the door fold, in particular behind the door be.
  • the pulling element is thus largely moved into the interior of the lock or the door or the lock case, where manipulation is therefore almost impossible.
  • the passage of the tension element is also unreachable, at least when the closure is closed.
  • the entry of the tension element from its anchoring point into the narrow side of the lock or into the lock housing is designed as a funnel-shaped opening that narrows from the outside inwards, the narrowest point of which in cross section is equal to or slightly larger than the cross section of the tension element is.
  • a switching bolt or actuator can be arranged, indirectly or directly, with which the switching element of an electrical switch and / or a locking piece of a lock for the bolt or for a drive part of the bolt in the sense of keeping this lock open when the lock is in the closed position is acted upon. If the switch is actuated, the closed position is displayed or, if the closure is not completely closed, there is a corresponding display or reaction signaling this open position.
  • a lock can be actuated so that the bolt can only be moved into its closed position when the lock or door is fully closed, so that mechanical monitoring of the closed position is also possible because only when the bolt is closed also the final closed position of the lock or the door means and closing the bolt past its bolt recess when the door is only ajar can be prevented by the lock.
  • a smooth and well-protected arrangement results when the pulling element with its switching pin or the like is mounted in a guide tube arranged transversely to the pivot axis of the lock or the door, in the case of a vertical pivot axis horizontal, at the end of the switching pin facing away from the hinge when the guide element is closed Door protrudes and into which this switching pin is at least partially retractable when the door is opened. This retraction is brought about by the relative movement already mentioned when the closure is pivoted open.
  • the cross section of the switching pin can correspond approximately to that of the guide tube.
  • the tension element can be constructed in the manner of a flexible shaft or can be composed of tensile and pressure-resistant members that can be pivoted relative to one another, provided it is not designed as a cable.
  • the deformability is important at least over the length of the tension element, which lies between its fixed anchoring and the area which, when the door is fully open, penetrates the passage into the door or the lock housing.
  • a flexible shaft is a very inexpensive component, which nevertheless has a high level of stability and, with good flexibility, also good pressure resistance.
  • a relative movement of the switching pin relative to the guide tube can also be arranged between the end of the switching bolt projecting radially from the rod and an abutment spaced therefrom, preferably the insertion funnel for the pulling element, in the guide tube or flexible rod.
  • This spring has the additional advantage that it serves as a spacer between the tension element and the inside of the guide tube, so that the deflected tension element can not or hardly lay against the inside of the guide tube and could make actuation difficult due to high frictional forces.
  • the spring can be designed as a helical spring and with its outer circumference almost fill the inner cross section of the guide tube.
  • a coiled spring can be well adapted to the inner cross section of the guide tube on the one hand, but on the other hand can accommodate a particularly round flexible rod or cable serving as a tension element in its interior.
  • the spring is a compression spring. It can thus assist in closing the relative movement of the switching pin and the pulling element in the interior of the guide tube located on the door or the lock case and make it easy to move. When opened, however, this compression spring is compressed accordingly by the relative movement in which the passage on the door or the lock housing moves away from the anchorage point of the rod.
  • the switching pin can have a tapered, in particular conical or rounded switching area at its free end, which, when the door is only ajar, with its smallest cross section has contact with a switching element or the like of the switch or the mechanical lock, and with its transition area to its largest cross section Switch and / or the mechanical lock actuated. If the door is only slightly open, neither the lock nor a switch is actuated, so that this position can be displayed or made noticeable.
  • the switch can control a display device for the door position and / or an alarm transmitter.
  • the respective position and above all the opening position can thus be made visible and, if necessary, audible.
  • the connection to an alarm device can optionally be switched on separately, so that in this way an additional fuse is also made for the closed door.
  • a particularly effective function of the device is obtained if the switching pin has two switching elements at the same time, namely the switch and the mechanical lock.
  • an indicator can be made visible via an electrical switch and the mechanical lock can be used to ensure that the bolt of the door or the lock cannot be accidentally closed past if the door or the lock are only ajar. If one of these devices fails, the other can still remain effective.
  • the relative movement between the switching pin and the door or the lock can be used in a variety of ways to actuate a mechanical lock.
  • a particularly expedient solution can consist in that the mechanical lock has a locking piece which can be displaced against the spring force transversely to a rod which can be moved with the bolt mechanism and which fits into a recess of this rod when the switching bolt moves back and the bolt mechanism is opened and the rod is shifted accordingly and when closing the door and pushing out of the recess releases the actuating rod and thus the drive linkage of the bolt work.
  • the bolt can actually only be actuated when the door is closed and then released, so that this bolt actuation is still prevented when the door is only ajar.
  • the locking piece can have a U-shaped cross-section, one U-leg of which is loaded with pressure by the switching bolt in the direction of the other U-leg and the other U-leg can extend in a recess on its between the two U-legs and by opening and closing the bolt slidable rod fit and be adjustable when the bolt is open and the switching pin withdraws from the locking piece.
  • the door-side end of the pulling element is arranged on a rotating part and part of the pulling element with the door closed the rotating part is wound and when the door is opened from the rotating part - due to the relative movement that then takes place - the rotating part has or actuates a switching cam which releases the switch, the lock or the like when the door is pivoted through an acute angle in the opening direction .
  • the greater thickness and thus the required greater length of the pulling element can be taken into account, i.e. a longer relative pulling out of the pulling element from the door can be effected without a correspondingly longer path for a relative movement in the direction transverse to the pivot axis in this or the lock case of having to consider the door.
  • a rotating drum provided with at least one circumferential groove which is optionally arranged in a helical manner can be provided as the rotatable part.
  • Rotary drums of this type are known per se and allow automatic winding and space-saving accommodation.
  • the automatic winding movement can - as is common with rotary drums with a winding circumference per se - by a corresponding die Drum driving coil spring can be effected.
  • the switch cam can be arranged relative to the switch, the lock or the like actuating part in such a way that it rotates less than 360 degrees with respect to the switch when the lock or the door is fully opened. As a result, multiple loading during the opening or closing movement can be prevented.
  • a particularly expedient and simple solution for realizing a single application during possibly several revolutions of the drum can take place in that the rotatable drum or similar winding part has a pinion arranged coaxially to it and connected to it in a rotationally fixed manner, which - indirectly or directly - a Gearwheel with switching cam acted upon.
  • this gearwheel itself only makes one revolution or, for safety reasons, the fraction of a revolution despite several revolutions of the drum.
  • the gear could mesh directly with the pinion or a chain transmission could be provided - possibly also a belt drive instead of the pinion and gear.
  • the tension element can be an electrical cable having at least two wires and can be connected to a circuit by interrupting which a display and / or alarm can be triggered. In this way, the device can also be used as a sabotage protection because an alarm is triggered when the cable is cut.
  • the two-wire electrical cable can be arranged in a flexible cable sheath in order to produce a uniform tension element despite the multiple wires or wires.
  • the electrical cable - forming the pulling element - is continued from the circumference of the rotatable drum to its end face and is arranged in a spiral with as many interlocking turns as the rotating part in Rotates at revolutions, and when the end of the electric cable supplied to the power source comes out of the drum or its housing near the axis of rotation.
  • a device for monitoring the in Figures 1, 4 u. 10 shown closed position of a swing door 1, flap or the like plate-shaped swivel or locking part in the exemplary embodiment for monitoring the closed position of an armored cabinet door, has an actuating element which can be moved by the pivoting of the door 1 and a switching element acted upon by this actuating element for an electrical switch 2 (FIG. 1 to 3 and Fig. 10 to 13) or for a mechanical lock 3 (Fig. 4 to 9).
  • the actuating member is a tension element 4, which is deflectable or flexible transversely to its longitudinal extent and has the shape of a rod-shaped part in the exemplary embodiments according to FIGS. 1 to 9, for which reason it is also called “rod 4" in the following, which rod 4 with its end 5 at a distance from the pivot bearing 6, that is, at a distance from the axis of rotation of the hinge of the door 1 on a fixed part on the hinge side of the door, that is to say on the side of the door 1, where the hinge is located.
  • the stationary part is arranged on a wall 8 of the housing or room closed by the door 1.
  • the tension element is also in the same way 4 according to the exemplary embodiment according to FIGS.
  • the rod 4 can also be deflected in the same direction as the door 1 by pivoting the door 1, its free end 9 opposite the fastening end 5 being shown in FIG
  • the closed position of the door 1 acts and actuates the switch 2 or the lock 3 in a manner to be described, and when the door 1 is pivoted it already by a small or acute angle into that shown in FIG. 2 or 9 Releases shown position in the opening direction, that is, away from the switch 2 or the lock 3 - seen relatively.
  • the switch 2 or the lock 3 move due to the different articulations of the door 1 on the one hand and the rod 4 on the other hand on different arches which bring together in the closed position of the door and in the opening direction of the door from each other remove.
  • the rod 4 is guided inside the door 1 or inside a lock housing 10 of the door 1, the door and its lock housing forming a unit in many armored cabinet doors.
  • the rod 4 protrudes from the lock housing 10 and is attached to the wall 8 of the housing or room closed by the door 1 or even to the door frame , welded in the embodiment.
  • the passage or entry 12 of the rod 4 is seen from the outside 13 of the door behind at least one fold 14 or even behind the door 1, so that at least in the closed position no manipulation of the star 4 and thus protected by the door 1 as a whole its actuating means are possible, from which an unauthorized person could benefit the next time the door is opened.
  • the entry 12 of the rod 4 from its anchoring point into the narrow side of the lock housing 10 is designed as a funnel-shaped opening 15 which narrows from the outside inwards, the narrowest point of which in cross section is equal to or slightly larger than the cross section of the rod 4 and which is located inside the door 1 or the lock housing 10.
  • the rod 4 has play relative to this funnel-shaped opening 15, which facilitates the deformation of the rod according to FIGS. 2, 3 and 9. It is avoided by this funnel-shaped opening 15 and its expansion towards the fixed end 5 of the rod 4 that the rod 4 is too bent or even bent when opening the door 1 and at the same time is too heavily loaded by the opening edge.
  • a switching pin 16 is arranged as an actuator, which when the door 1 is in the closed position according to FIG. 2 and according to FIGS. 4 to 7, the switching element 17 of the electrical switch 2 or a likewise switchable locking piece 18 of the lock 3 for the bolt 19 or for a drive part, in the exemplary embodiment a rod 20 movable with the bolt mechanism in the sense of keeping the lock 3 open. Since the rod 4 is pressure-resistant, when the door is closed, it can fix the switching elements mentioned, that is to say the switching element 17 of the switch 2 or the locking piece 18 of the lock 3, against a restoring force.
  • the rod 4 with its switching pin 16 is mounted on all sides enclosed in a horizontal guide tube 21 in a transverse direction to the pivot axis A of the pivot bearing 6 of the door 1, in the case of the pivot axis A arranged vertically in the exemplary embodiment and led. From this guide tube 21, the switching pin protrudes at its end facing away from the hinge or pivot bearing 6 when the door 1 is closed according to FIGS. 1 and 4 to 7.
  • the switching pin 16 Due to the opening movement of the door, the switching pin 16 is due to the relative movement already described on the one hand the switching pin 16 and on the other hand also the guide tube 21 on different swivel bends, relatively speaking, retractable into the guide tube 21 or vice versa, the guide tube 21 is pushed over the end of the switching pin when the door is opened, but at the same time the switch 2 or the lock 3 be removed from this switching pin 16.
  • the cross section of the switching pin 16 corresponds approximately to that of the guide tube, so that it carries out a precise relative movement.
  • the rod 4 is constructed in the manner of a flexible shaft, so that it the deformations which result when the door is opened, which lead to different bends between its fixed end 5 and the inlet 12 when this inlet 12 becomes more and more different removed the end 5, can perform.
  • the insertion funnel 24 containing the conical or funnel-shaped opening 15 for the rod 1 is a relative movement of the switching pin 16 arranged opposite the guide tube 21 supporting spring 25 which is designed as a helical spring and almost completely fills the inner cross section of the guide tube 21 with its outer circumference. It thus also serves as a spacer for the rod 4 opposite the inside of the tube 1 and facilitates the relative movements occurring when the door is pivoted between the guide tube 21 and the rod 4.
  • the spring 25 is a compression spring, so that it is most tensioned in the largest opening position shown in FIG. 3, even if due to the deformation of the elastic restoring forces Rod 4 and thus its possible tilting at the funnel-shaped opening 15 and the possible tilting of the switching pin 16 with respect to the inside of the guide tube 21 are greatest.
  • the switching pin 16 has at its free end 26 a tapered switching area which is conical according to FIGS. 1 to 3 or rounded according to the other figures and which, with the door only ajar, with its smallest cross section comes into contact with the switching element 17 of the switch 2 or with the locking piece 18 the lock has 3. With its transition area to its largest cross section, this conical end 26 can actuate the switch 2, while in the exemplary embodiment the mechanical lock is brought into the closed position by a tension spring 27 when the switching pin 16 withdraws from the locking piece 18, but conversely the locking piece 18 from the switching pin 16 is actively moved out of its locked position when the door 1 is completely closed (Fig. 5 to 7).
  • the switch 3 can, for example, control a display device for the door position or possibly - also additionally - an alarm transmitter.
  • a display device for the door position or possibly - also additionally - an alarm transmitter can, for example, control a display device for the door position or possibly - also additionally - an alarm transmitter.
  • the leaned position of the door 1 shown in FIG. 2 can also be displayed, in which a bolt 19 could possibly be accidentally closed past its bolt opening 28, so that the door 1 would not be closed at all.
  • the mechanical lock 3 has the locking piece 18 which can be displaced counter to the spring force by the switching pin 16 transversely to the rod 20 which can be moved with the bolt mechanism and which, when the switching bolt 16 retracts and the bolt 19 is open as shown in FIGS. 8 and 9 and the rod 20 correspondingly displaced, into a recess 29 this rod 20 fits and is also indented by spring force.
  • the locking piece 18 is also pushed out of the recess 29 in the rod 20, so that the rod connected to the drive linkage of the bolt work or a lock 30 is returned to the one in FIG. 5 position shown can be moved.
  • FIGS. 6 and 7 show the position in which the lock 30 is open, but the bolt 19 is closed, the locking piece being arranged in the region of the recess 29 of the rod 20, but is out of engagement.
  • the door 1 is thus closed, so that the aforementioned actuation of the lock 30 for closing the bolt 19 can take place unlocked. 5 and 4, the rod 20 is raised so that the locking piece 18 could no longer enter the recess 29.
  • Fig. 8 and 9 it is shown that the lock 30 and the bolt 19 are open, so that from the position shown in Figs. 6 and 7 after pulling back the bolt 19, the door swung into the position shown in Fig. 9 can be, then the locking piece 18 gets into the recess 29, so that now the closing of the lock 30 - with little open and even more completely open door - is prevented.
  • the lock 3 actuated by the rod 4 and the switching pin 16 thus serves to be able to operate the lock 30 only when the door 1 is completely closed, and thus allows the closed position of the door 1 to be checked in this way.
  • the locking piece 18 has a U-shaped cross section, one U leg 31 of which is loaded with pressure by the switching pin 16 in the direction of the other U leg 32.
  • This other U-leg 32 fits into the recess 29 on the extending between the two U-legs 31 and 32 and displaceable rod 20 and is adjustable in this locked position when the lock 30 and thus the bolt 19 are open and the switching pin 16 when swiveling the door backs away from the locking piece 18. This is shown in Figures 8 and 9.
  • the switching pin 16 or switching block When the door is closed, the switching pin 16 or switching block is pushed at the end of the flexible rod 4 in the direction of the switch 2 or the locking piece 18 and can thus actuate and actuate the switch or the lock so that the complete closing of the door 1 is indicated or the door can only be locked when it is fully closed.
  • the necessary parts, namely the rod 4 to be fixed to the wall 8, the guide tube 21 and a switch 2 or a lock 3 can also be retrofitted to such a door 1 or in its lock housing 10, so that these Securing option even with existing systems without their complete replacement, that is, can be realized with relatively low investment costs.
  • this third exemplary embodiment differs from the two solutions described above in that the door-side end of the tension element 4 is arranged on a rotatable part and part of the tension element 4 is wound on this rotatable part when the door 1 is closed and can be unwound when the door 1 is opened , as the comparison of Figures 10 and 11 illustrates.
  • the rotatable part is a rotary drum 34 provided with at least one helically arranged circumferential groove 33, which in the manner to be described still has or actuates a switching cam 35 which, when the door 1 is pivoted through an acute angle in the opening direction, is also provided in this exemplary embodiment Switch 2 - but possibly also a lock 3 - releases.
  • the switch cam 35 is arranged relative to the switch 2 - possibly to the lock 3 - in such a way that it rotates less than 360 degrees with respect to the switch 2 when the lock or door 1 is fully opened. This is because the rotary movement of the rotary drum 34 is used for the aforementioned movement of the switch cam 35 and thereby the actuation of the switch 2.
  • the rotating drum 34 in the exemplary embodiment has a pinion 36 which is arranged coaxially with it and connected to it in a rotationally fixed manner and which acts on a gear 37 having the switching cam 35 to such an extent that, when the rotating drum is rotated several times, it performs only one or less than one revolution and thus avoids multiple loading of the switch 2 with the switching cam 35.
  • the tension element 4 in this exemplary embodiment is, instead of a flexible and deflectable rod, an electric cable 39 having at least two wires 38, which wires 38 have a common insulating sheath 40, for example a round wire sheath.

  • the end of the electrical cable which can be supplied to the power source emerges from the drum 34 or its housing 43 near the axis of rotation 41, so that a firm connection is established is possible with a circuit or a power source and sliding contacts can be avoided despite the rotary movement.
  • the end 5 of the tension element 4 facing away from the rotary drum 34 has in this case a cable loop 44 so that the two wires 38 can merge into one another continuously. This loop can be seen in FIG. 12.
  • FIGS. 10 to 14 advantageously allows a pulling element 4 to be accommodated on the one hand in a space-saving manner despite a greater length, for example for a correspondingly thick door, in that part of its length is closed, for example with a coil spring, when the door is closed
  • Rotary drum in particular can be wound up automatically and, on the other hand, the pulling element 4 can also be designed as a sabotage protection, if appropriate in the preceding exemplary embodiments, in that it is an electrical cable connected to a power source.
