Definitions

  • the invention relates to a bolt actuation device with a locking unit having a locking bolt and an electrical actuating device, the locking device having a direct-current, right-handed, direct-current electric motor, the direction of rotation of which can be controlled by polarity changeover, and a gear for converting the motor rotation into a longitudinal movement along the motor rotation axis is.
  • Bolt actuation devices of this type are used in conjunction with an intrusion detection system to prevent a door from being opened when the alarm system is armed. Only when the alarm system is in the disarmed state can the bolt be pushed back and the door opened. It is known to operate the locking bolt with a mechanical key lock. Actuations with the aid of electromagnets are also known, an electromagnet for opening and a further electromagnet for closing the bolt being required.
  • DE 36 31 043 C1 discloses a generic device, in particular for motor vehicle door locks, which has a reversible electric motor. This drives a spindle drive for the bolt via a coupling. Due to its dimensions and construction, such a device is not suitable for installation in a conventional door or door frame of a building.
  • the invention has for its object to provide a bolt actuating device of the type mentioned, which works particularly safely and reliably and can be installed in a conventional door or a conventional door frame.
  • This object is alternatively achieved in that the bolt is aligned transversely to the motor shaft and that there is a flexible shaft or a toggle lever between the gear and the bolt, with which or with which the longitudinal movement is converted into a transverse movement.
  • the invention has the advantage that the individual components can have small geometric dimensions and are therefore suitable for installation in all common door frames and door leaves.
  • the transmission has a spindle drive which is driven by the shaft of the electric motor, that the spindle drive acts on one end of the flexible shaft and that the other end is attached to the bolt. In this way, a positively guided deflection of the longitudinal movement into a cross-bar movement is achieved.
  • housing-fixed guide means preferably spaced bolts, are provided which facilitate the deflection of the flexible shaft.
  • a positively guided deflection of the longitudinal movement into a crossbar movement is achieved in that the spindle drive acts on two articulated lever arms, one of the lever arms being fixed in place and the other articulated on the bolt (toggle lever).
  • a preferred development of the invention is that means for mechanical emergency unlocking in the event of danger are also present in the event of a power failure or functional failure of the actuating device.
  • the bolt can be unlocked using a tool.
  • the bolt has a longitudinal groove for receiving the flexible shaft when the bolt is in a bolt guide.
  • a releasable mechanical blocking device for the bolt In order to prevent an unauthorized person from gaining access by forcibly pushing back the bolt, it is advantageous for a releasable mechanical blocking device for the bolt to be present in its extended position.
  • the blocking device is controlled by the spindle drive.
  • the movement of the spindle drive when the bolt is actuated is simultaneously used to actuate the blocking device.
  • the blocking device has a blocking pin which is moved by a slider which is displaceable on the spindle.
  • the emergency release can be ensured in a simple manner in that the motor and the gearbox are combined as one unit, for example on a mounting plate, that this unit is arranged so that it can be displaced away from the bolt in a housing in the direction of the motor shaft for emergency release, that the bolt is separate is arranged displaceably in the housing, and that a holding device is present, which detachably holds the unit in an operating position.
  • the holding device is a spring which is supported on the housing.
  • the locking bolt prefferably has a round cross section and for the door or door frame side to have a corresponding round bushing for receiving the locking bolt.
  • the round cross-section has the advantage that the bush can be easily installed with a conventional drilling tool.
  • the cross section can be both circular and oval.
  • the operational safety is further increased by the fact that current monitoring and / or torque monitoring is provided to protect the electric motor from being stuck.
  • Another advantageous embodiment of the invention is that a coding device on the switching device side and a decoding device and an evaluation circuit on the adjusting device side are present, and that motor control takes place only when on the electric motor a coding specified in the switching device is present.
  • the direct current motor is energized only if the coding on the alarm center on the one hand and the actuating device on the other hand match. Otherwise the actuator will not be activated.
  • the coding is carried out by means of an electrical signal superimposed on the motor supply voltage. In this way, separate transmission paths for the coding can be omitted.
  • Fig. 1 denotes an actuating device for a locking bolt 3, which is installed in a frame 2 of a door.
  • the associated parts are shown in the drawing in a partial cross section.
  • a bushing 11 with a flange 7 for receiving the locking bolt 3 is installed flush in a door leaf 8, which can be seen in FIG. 1 in the extended locked position (end position) in the bushing 11.
  • the locking bolt 3 is driven by a direct current electric motor 4, which is controlled via a line 12 by an alarm center 10 of an intrusion detection system.
  • the alarm system is armed or disarmed with the aid of a separate control unit 9, which is located outside the area protected by the alarm system.
  • the alarm system can be armed on the control unit 9.
  • the electric motor 4 is energized in the actuating device 1 from the alarm center 10 and extended into the end position shown.
  • the door leaf 8 is thus locked. The door can only be opened if the alarm system on the control unit 9 has previously been switched off or disarmed.
  • the actuating device 1 has a housing 1a, which in the example shown consists of stable zinc die-casting and can be installed in a frame 2.
  • the locking bolt 3 here has a circular cross section.
  • Fig. 2 shows the locking bolt in the retracted state.
  • the electric motor 4 is fastened on a mounting plate 17 which is attached to the inside of the actuating device 1.
  • the electric motor 4 has a shaft 22 which is connected to the locking bolt 3 via a gear mechanism, by means of which the rotary movement is deflected into a transverse bolt movement.
  • the motor shaft 22 is connected to a spindle 13 via a coupling 15.
  • the other end of the spindle 13 is mounted in a guide bush 27.
  • a guide piece 16 sits on the spindle 13 for receiving one end of a flexible shaft 18.
  • the guide piece 16 is a slide piece with an internal thread.
  • the spindle drive, formed by the spindle 13 and the guide piece 16 sets the rotary movement of the electric motor 4 into a translational movement of the guide piece and that attached to it flexible shaft 18 um.
  • the guide piece 16 is guided in a guide which can have a mechanical stop, for example. If the guide piece 16 is in the end position - locking bolt 3 extended - the violent pressing in of the locking bolt 3 is prevented.
  • the other end of the flexible shaft 18 is attached to a clamping piece 19 which is connected to the locking bolt 3.
  • guide elements which serve to guide the flexible shaft 18.
  • these can be round bolts, which are fastened vertically offset on the left and right on the housing 1a and thus form a guide for the flexible shaft 18.
  • a circuit board is designated, e.g. Has electronic components for controlling the electric motor 4.
  • a supply line 25 is provided for the electrical connection of the electronic components and is introduced through the housing base.
  • the entire arrangement consisting of motor 4 and mounting plate 17 as well as shaft 22, spindle 13 and guide piece with guide bushing 27 is installed such that it can move vertically. In the normal state, this arrangement is locked vertically and cannot be moved.
  • the device 1 can be mechanically unlocked using a special tool.
  • a special tool for this purpose, there is a bore or recess 23 on the outer housing 1a, into which a special tool can be inserted externally.
  • the flexible shaft 18 can be subjected to both pressure and tension.
  • the flexible shaft 18 is moved in the direction of the spindle 13 or the coaxial motor shaft 22 by the spindle drive 13, 16. Since the flexible shaft is attached to the locking bar 3 on the one hand and is deflected by 90 degrees via the guide elements 20, 21, the longitudinal movement of the guide piece 16 is deflected into a transverse movement of the locking bar 3.
  • the locking bolt causes the device to be locked or unlocked.
  • the flexible shaft 18 is pressurized and thereby pushes the locking bolt outwards.
  • the flexible shaft 18 is subjected to tension and thereby moves the locking bar 3 inwards.
  • the flexible shaft can be made of any flexible material. e.g. round material made of nylon, round spring steel or a flat spring steel can be used. Other materials with similar properties are also conceivable, e.g. a flexible wire with appropriate rigidity and flexibility.
  • position sensors 5, 6, which are queried and evaluated by the alarm center 10.
  • These position sensors 5, 6 can be, for example, contactless fork or reflection light barriers or capacitive or inductive proximity switches.
  • the two end positions of the guide piece 16 and the locking bolt 3 are monitored by position sensors 5, 6, which are queried and evaluated by the alarm center 10.
  • a monitoring unit 64 evaluates the motor operation, for example via a torque monitor or a current monitor, in order to protect it against sticking, for example.
  • a decoding device 65 (FIG. 5) which decrypts and evaluates decoded signals from the alarm center 10.
  • the DC motor 4 is energized only if a permissible code is transmitted.
  • the DC motor 4 runs counterclockwise or clockwise and thus opposite locking movements are achieved by applying different polarities to the power supply.
  • the bolt 3 has a longitudinal groove 30 on its side facing the spindle drive 13, 16. It receives the flexible shaft 18 within a bolt guide 31.
  • the shape of the bolt guide 31 can therefore correspond to the outer contour of the bolt 3.
  • the bolt 3 If the bolt 3 is in the end position, it is secured against being pushed back by a blocking device controlled by the spindle drive 13, 16.
  • a blocking pin 14 fastened to the guide piece 16 moves with the guide piece 16 behind the bolt 3 or into a recess 15 in the bolt 3.
  • the spindle drive 13, 16 moves in the opposite direction, the blocking is released.
  • FIG. 3 shows an emergency release in which the mounting plate, including the components arranged thereon, is pushed down from the operating position shown in FIG. 2 by means of a cam lever 28. Because here automatically the blocking device 14, 15 for the bolt is released, the flexible shaft pulls it back into the housing 1a. The cam lever 28 is accessed via the cutout 23. The spindle drive 13, 16 is not actuated. In the emergency unlocked state, the cam lever 28 spreads in front of the mounting plate 17 and in this way prevents it from being pressed back by the spring 24 into the operating position and the locking position of the bolt 3.
  • Fig. 4 shows the bolt 3 in its retracted position, in which it was brought by operating the motor 4 and the spindle drive 13, 16 in the usual operating mode.
  • the electric motor 4 is pivotally mounted on a pin 54, the pin 54 extending perpendicular to the motor shaft 55.
  • the motor shaft 55 is connected to a spindle drive 13, 16.
  • a toggle lever 53 consisting of two articulated lever arms 57, 58, on the connecting joint 59 of which the guide piece 16 is articulated.
  • the two lever arms 57, 58 are articulated via pins 60, 61 on the housing 1a or on the locking bolt 3, the pins 60, 61 running parallel to the axis of the connecting joint 59 and to the pin 54 on the electric motor 4.
  • the connecting joint 59 is moved in the direction of the spindle 13 or the coaxial motor shaft 55 by the spindle drive 13, 16. Since the spindle 13 or the motor shaft 55 runs at an angle to the imaginary connecting line between the two bearing journals 60, 61 of the lever arms 57, 58, the two lever arms 57, 58 cause a longitudinal displacement of the locking bolt 3.
