Definitions

  • the invention relates to a device for monitoring the closed position of a pivotable closure according to the preamble of claim 1.
  • Such a device is known from DE-C-473 292.
  • a tensioned protective wire is used to close an alarm circuit using a friction clutch.
  • the protective wire is freely accessible on the side of the closure after which it is pivoted when it is opened. It is therefore freely accessible from this opening side and could therefore be manipulated in a simple manner. This would be completely useless, especially with secured rooms or containers and in particular armored cabinet doors.
  • Such an arrangement can be installed easily - even on an existing lock or door, i.e. also retrospectively, and is largely resistant to manipulation due to the simplicity of the construction but also because of the accommodation inside the door or a lock housing due to the protected accommodation secured.
  • the mechanism is very simple and therefore little or not susceptible to failure, since it can be exploited that two spaced-apart fastening points have pivotable parts, one of which is carried by the pivoting of the other, at their ends different, distant paths or Describe curves so that these differences in path when pivoting the closure to Operate a switch, a lock or another signal or actuator can be used.
  • the pivot center lies in the hinge of this door, while the pulling element is pivoted and / or bent relative to an area which is offset by a distance from it and which is arranged on a stationary inner wall of the locked space, so that its free end is opposite want to remain in its original position relative to the lock or door more and more towards its hinge.
  • this end or the end region is pushed relative to the inside of the lock or the door away from its hinge or withdrawn into an initial position and can thereby actuate the switching element of a switch or a mechanical lock.
  • the pulling element is an electrical cable which has at least two cores and which, when interrupted, triggers a display and / or an alarm
  • the device can be used at the same time as a tamper protection device, because the above-mentioned display and / or alarm is triggered when the cable is cut.
  • the tension element thus has a double function.
  • the traction element in a manner to be described in several exemplary embodiments, expediently be a tensile and pressure-resistant, deflectable or flexible rod-shaped part transverse to its longitudinal extension, for example in any cross-sectional area, that is to say 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 tension 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 at least inaccessible 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 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 tension element is.
  • a switching bolt or actuator can be arranged, directly or indirectly, 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 the 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, on 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. This results in a defined deflection and relative movement of the switching pin with respect to the closure and the opening and closing switching element of a switch or a lock provided there.
  • 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 that 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 that penetrates the passage into the door or the lock housing when the door is fully open.
  • a flexible shaft is a very inexpensive component, which nevertheless has high stability and, with good flexibility, also good compressive strength.
  • 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 opening, 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 anchoring point of the rod more and more.
  • 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 device.
  • 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 securing of the closed door is also established.
  • 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 the fact 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 in 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 boltwork.
  • the bolt can actually be actuated only 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 tension element is arranged on a rotating part and part of the tension element with the door closed the rotary part is wound and when the door is opened from the rotary part - due to the relative movement that then takes place - the rotatable 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 tension element can be taken into account, i.e. a longer relative pull-out of the tension 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.
  • the rotating part can be a rotating drum provided with at least one circumferential groove which is optionally arranged in a helical shape.
  • Such rotating drums are known per se and allow automatic winding and space-saving accommodation.
  • the automatic winding movement can - as is usual 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 - directly or indirectly - a Gearwheel with switching cam applied. With a corresponding reduction it can be achieved that this gear wheel itself makes only one revolution or, for safety reasons, the fraction of a revolution, despite several revolutions of the drum.
  • the gearwheel could mesh directly with the pinion or a chain transmission could be provided - possibly also a belt drive instead of the pinion and gearwheel.
  • the electrical cable can be arranged in a flexible cable sheath. Despite the multiple wires or wires, this results in a uniform tension element.
  • 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 stationary 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 Released position shown in the opening direction, that is, from the switch 2 or the lock 3 - relatively speaking - away.
  • 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 fastened to the wall 8 of the housing or room closed by the door 1 or even to the door frame, welded in the exemplary 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 is equal in cross section or slightly larger than the cross section of the rod 4 is 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 bent too much when opening the door 1 or even kinked and at the same time too heavily loaded by the opening edge.

Since the rod 4 is pressure-resistant, it can, when the door is closed, 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 in a horizontal guide tube 21 in a horizontal guide tube 21 in a manner transverse 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, as shown in 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 resulting 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.

It thus also serves as a spacer for the rod 4 opposite the inside of the tube 1 and facilitates the relative movements occurring between the guide tube 21 and the rod 4 when the door is pivoted.
  • 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 against elastic restoring forces Rod 4 and thus its eventual tilting at the funnel-shaped opening 15 and the eventual 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 locking piece 18 is also pushed out again from 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 shown position 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. If the lock 30 is now brought into the closed position, the rod 20 is raised as shown in FIGS. 5 and 4 so that the locking piece 18 could no longer enter the recess 29.

  • 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 switching cam 35 and thereby the actuation of the switch 2.

  • 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 made 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 tension element 4 to be accommodated on the one hand in a space-saving manner despite the greater length, for example for a correspondingly thick door, in that a 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 necessary in the preceding exemplary embodiments, in that it is an electrical cable connected to a power source.
