Definitions

  • the invention relates to a mechanically and electrically coded device for Locking and unlocking a movable in a first fixed part stored second part with the help of locking means, by one as electromechanical Transformer trained actuator are separated and from one Actuator assigned, movable by this on an axis
  • a actuator Implementation of the locking and unlocking are so adjustable that the in the first part led locking means in the locked state in at least one Grab the second part and get out of the unlocked state Engage with the second part and its movement relative to the first Allow part, provided that the user codes are predefined to the aforementioned ones Codes fit.
  • From DE 40 29 208 A1 is a cylinder lock with mechanical and electronic Coding known.
  • This lock has a locking mechanism also from an electromagnetic actuator, which if there is a match the user code is triggered with a predefined code and acts on locking agents. These are formed by a locking pin that with an annular locking disk assigned to your cylinder core of the lock cooperates. This is placed on the cylinder core and by means of it a penetrating fastening pin rotatably connected.
  • the lock washer has a recess into which one of the free ends of the actuator is energized the intended pin and thus block or release the Cylinder core can cause.
  • Such an embodiment also has one Large number of interacting, complicated to manufacture individual parts and is therefore expensive to manufacture and quite voluminous.
  • the object of the invention is to provide a locking device, which with high functional reliability and relatively simple function from only consists of few parts, is small in size and manufactured at particularly low cost can be.
  • the locking means preferably consist of at least a rolling element that during the unlocking process only under the influence of Gravity automatically on its trajectory in the aforementioned first position can roll if the course of this path in relation to axis A like mentioned is chosen.
  • the actuating element is expediently a pressure piece with an inclination to the axis A. Roof surfaces formed over which the locking means or rolling elements Movement of the pressure piece on the axis A in one direction, with vertical Position axis A upwards, be pressed into its second position.
  • Each rolling element is provided with a roof surface that leads to the movement path of the associated rolling body is inclined at a predetermined angle.
  • a particularly favorable version of the device gives you two Rollers are provided as locking means, which are associated with their Movement path and roof area each diametrically and mirror-symmetrically symmetrical opposite to axis A, since it is achieved in this way that on the Actuator and the moving parts assigned to it do not have any side forces can.
  • an actuator that can be controlled electrically via a predetermined code comes as an actuator Magnet into consideration.
  • other actuators are also suitable, such as electrically controllable expansion body to be operated with electricity.
  • electrically controllable and actuatable magnets prove themselves particularly well, however, because these magnets depend on the task at hand can be designed as a lifting magnet or as a pull magnet, which depends on whether in the electrically de-energized state the movably mounted second part of the Locked or unlocked device with the first fixed part should. If both parts are locked in the de-energized state of the magnet, it must energized to unlock the magnet. Then there is a pull magnet required that unlocks the device when energized. The opposite is true itself when the device is in the de-energized state of the actuator or magnet should be unlocked. Then the actuator must be locked after entering the specified codes are energized. A lifting magnet then moves the locking means with the help of the roof-shaped pressure piece in their respective recordings.
  • expansion bodies have also proven themselves as actuators because they sometimes even smaller than electromagnetic actuators.
  • Can be used as an expansion body For example, a bi-metal can be used that heats up by energization and is deflected sideways. This deflection can vary depending on the predefined Initiate the task of locking or unlocking the device. in the the other advantage of such a solution is that up to the inverted Execution of an entered signal after its delete command certain delay occurs due to the cooling time of the bi-metal. This can Particularly important for safety-relevant locking mechanisms to have.
  • the locking mechanism on the electrical side through a self-sufficient energy supply e.g. through an accumulator or a battery, powered, bending piezo elements can also be used as actuators be.
  • actuators e.g. through an accumulator or a battery, powered, bending piezo elements
  • These are in effect and execution related to the execution of the Input signal commands comparable to the mode of action of a bimetal. she However, due to their piezoelectric properties, they only need to be used during the actual movement time of less than a millisecond of energy. Even If the input signal is present for a longer period, there is practically no power needed because these elements then behave like a charged capacitor and only a negligibly low leakage current is required.
  • actuators made of shape memory metals.
  • the actor is forced into a form that he takes only when a certain temperature is reached. If this temperature is exceeded or fallen below, the actuator takes another predetermined form on.
  • such an actuator can, for example, consist of a spiral or Coil spring exist, which is a large preloaded in the normal temperature range Has length and exerts a force which, for example, is designed as a rolling body Locking means fixed in their receptacles. If this spring z. B. as electrical resistance element formed, which is when an electrical The current is heated to the specified temperature, the is reduced Length of the spring to its predetermined value. Here, the rolling elements released and the device unlocked. Lowering this elevated temperature then the spring returns to its original value exerting length, and the rolling elements are again in the recordings moved and fixed and thus locked the device.
  • the cylinder lock 1 consists of a first fixed part 2 and one guided here, rotatably mounted second part 3, which with a rotating Groove 3.1 is provided, which in the unlocked state of the lock Latch means 4, which here consist of two rolling elements 5 and 6, by partial This rolling element engages in the groove without the locking means Exercise the blocking function (Fig. 2 and 4).
  • the groove 3.1 with recesses to form Provide recordings 8.1, 8.2 for one roll body each. These recordings are introduced at an angle ⁇ obliquely to the longitudinal axis A of the actuator 7 in the part 3.
  • the rolling elements 5 and 6 are each based on an associated roof-shaped Sloping surface 9.1, 9.2 of a pressure piece 9, the roof surfaces one Include angle ⁇ and run symmetrically to axis A.
  • the actuator 7 is a pull magnet.
  • This consists of a current-carrying coil 10.1, which is applied to a coil body 10.2 is which has a hollow receptacle. In this one is in the one of the movable one Part 3 facing away from a ferritic core 10.3 firmly introduced.
  • an armature 10.4 is axially movable. The armature is de-energized by the core by a spring 10.5 10.3 kept at a distance. Otherwise, the pressure piece 9 is with the anchor 10.4 connected.
  • the core 10.3 pulls the Anchor 10.4 against the force of the spring 10.5.
  • the two rolling elements 5, 6 can then roll out of the recordings 8.1, 8.2 and attach to the respective one Roof area 9.1, 9.2 of the pressure piece 9 obliquely as shown down and inside on the part 2, the rolling elements also on the side leading motion trajectories 2.1, 2.2 roll until they finally only in Area of the circumferential groove 3.1 of the movable second part 3 are. This is then unlocked from the first part 2 (Fig. 2) and freely around its longitudinal axis for example rotatable with a key.
  • the device shown in FIG. 4 it is in the de-energized state Actuator in the unlocked state.
  • the armature 12 of the actuator or magnet is included a tappet 13 connected on which the pressure piece already described 9 is attached to the armature end facing the movable part 3.
  • the plunger 13 penetrates the core 11 in an axially movable manner.
  • the force of the compression spring 10.5 causes the armature 12 at a distance from the core 11 in the de-energized state is held.
  • the armature 12 When the coil 10.1 is energized, the armature 12 is pulled against the core 11, the plunger 13 lifts the pressure piece 9 and this in previously described Way the rolling body 5, 6 with an axially and radially directed movement component moved on the trajectories in the first part 2. If in this state, the recordings 8.1, 8.2 do not overlap with one the rolling element are located and they only engage in the circumferential groove 3.1, is the second part 3 still rotatable, with a mechanically suitable coded Key until the recordings 8.1, 8.2 finally face the rolling elements and the rolling elements that are still under the force of the actuator in their respective recording can be pushed. Then the one shown in Fig. 3 Condition reached and the device locked.
