Definitions

  • the invention relates to a key card with a regionally magnetized insert between its two parallel broad side surfaces, which have a length and width that is considerably greater than the thickness defined by the wide side spacing.
  • the object of the invention is based on the object of increasing the security value of a key card of the type in question.
  • This object is initially and essentially achieved with a key card with the features of claim 1, the aim being to provide at least one elevation on at least one of the two broad sides, the magnetized regions of the insert lying outside the profiling formed by the elevation.
  • a generic key card of increased security value is specified. Due to the surveys on at least one of the two broad sides, it is largely prevented that the magnetic information from in the immediate vicinity stored code cards is destroyed. The surveys have such an overhang that only weakened field strengths act on the code strip. It was found that, for example, half a millimeter is sufficient for the elevations. Nevertheless, it is ensured that the magnetic areas of the insert, which lie in the valleys of the profiling formed by the elevations, properly perform their closing function. This means that the locking security is not impaired.
  • One way to form the elevations is to provide one or more longitudinal ribs on the broad side surface.
  • the longitudinal rib or the longitudinal ribs are placed on the edge of the card, so that the longitudinal rib can be produced, for example, by bending the longitudinal edge. Furthermore, it is possible to form the elevations by a multiplicity of humps, knobs or projections lying at a distance from one another on the width side surface of the key card. In addition, there is the possibility of producing a U-shaped cross-sectional shape of the key card, the U-legs representing the longitudinal ribs.
  • the locking device consisting of lock and key card, which has a plurality of magnetic hold-ups which can be displaced transversely to the card plane through magnetized areas of the key card, one broad side of which is in an adjacent parallel position to the broad side of a narrow insertion slot for the key card, is characterized in that the broad side of the insertion slot opposite the profiled broad side of the key card has a profile which is essentially negative with respect to the key broad side profiling, the magnetic hold-ups protruding inwards Area of the diaphragm wall profile.
  • the stop shoulder lies outside the slot cross section corresponding to the thickness of the card section forming the coded fields.
  • the increased security value relates in particular to security against manipulation.
  • a key card of a locking device known from the prior art is not able to move the slide even with correct surface coding due to the special position of the stop shoulder of the slide.
  • the stop shoulder extends outside the slot cross section.
  • a corresponding key card must therefore be used, which can act on the stop shoulder of the slide located outside the slot cross section and can thus drag the slide with it.
  • the relevant stop edge of the key card is formed by an elevation of the key card. With the aid of a key card which does not have an elevation, no locking operation can be carried out, apart from merely inserting the key card.
  • Another feature of the invention is characterized in that the stop edge is upstream of at least one coded field in the direction of insertion.
  • the stop edge is formed by the end face of a rib of the key card extending in the direction of insertion. This can be molded on when producing the key card. If necessary, it is possible to subsequently fix a corresponding rib at a predetermined location by gluing, etc.
  • the rib is arranged on the edge of the key card.
  • An advantageous embodiment of the invention is characterized in that the coded fields are magnetized areas of the key card and / or a rib also has magnetically coded fields for interaction with additional tumbler pins arranged on the edge of the slide. In this way, a multiple function of the rib is even realized, since in addition to the slide displacement, it is also used to classify additional tumbler pins.
  • the multiple function of the rib is further increased in that the rib has an incision for engaging a supplementary tumbler or the like which mechanically activates when the slide or the key card is displaced. In the correct key insertion position, the incision is then aligned with this additional tumbler. Only when the slider is moved forward does the supplementary tumbler come into play in conjunction with an entry into the incision of the rib, so that a coupling between the slider and the card is created in this way.
  • a variant of the key card is characterized in that the stop edge is formed by a tab which swings out of the first level when the key card is inserted. Before the key card is inserted, the stop edge therefore extends within the cross-sectional area of the card section forming the coded fields. When the key card is inserted, the flap is then swiveled out in such a way that its stop edge extends outside the cross-sectional area of the card section and accordingly is able to step against a correspondingly positioned stop shoulder of the slider and then drag it along.
  • the procedure is such that the tab forms a control cam protruding from the first level on the side opposite the pivoting direction.
  • this is acted upon by a region on the lock side and connected to a pivoting of the tab, the stop edge of which reaches the position suitable for the control.
  • a channel is provided which adjoins the insertion slot and extends in the insertion direction and which is closed at the end by the stop shoulder.
  • the rib runs through this channel when the key card is inserted until the rib-side stop edge abuts the stop shoulder. Only then is it possible to take the slide with you.
  • the channel is advantageously arranged on the slide side.
  • a recess is arranged in front of it in the plane of the channel for receiving a slide locking lever controlled by the key card.
  • the key card When the key card is inserted, the latter is moved. Then the pilot control of the Slider including the slide locking lever, the latter can be engaged by a retaining spring, which secures the forward position of the slide. Only when the key card is withdrawn can the slide securing lever be pivoted spring-loaded into its starting position, so that a return spring can then pull the slide back into its starting position.
  • the lock has a supplementary tumbler pin opening into the channel.
  • the latter is controlled after the key card has been inserted and the slide has been moved forward in the direction of the key card, and its head enters the rib received by the channel or the incision thereof.
  • the channel is formed in the form of a slide-side corner recess.
  • a variant is characterized in that the stop shoulder is formed by the one arm of a two-armed clutch lever, which has a latching cam which, when the card is inserted, dips into one of the cards associated with the latching recess forming the stop edge. While in the previous exemplary embodiments the stop shoulder is stationary on the slide, there is now a movable stop shoulder, namely on one arm of the clutch lever. When the card is inserted, it is pivoted in a tactile manner, the locking cam being inserted into the locking recess assigned to the card. When the card is inserted further, the stop edge of the locking recess comes into driving connection with the locking cam and thus drags the slider into the operative position via the coupling lever.
  • the clutch lever When the key card is withdrawn, the clutch lever is released for pivoting, the locking cam then leaving the locking recess.
  • the other arm of the clutch lever is used to form the key surface to be acted upon by the face of the key card.
  • a strong joint engagement is achieved by the fact that the locking recess is assigned to the rib.
  • the button is accordingly on the front of the rib and thus also on that of the key card. If the clutch lever in the advanced position of the slide acts together with a retaining spring for locking the feed position of the slide, it is advantageous if the length of the locking recess in the direction of insertion is greater than the length of the locking cam. If the key card is removed, the latching cam can initially move within the latching recess. When it comes to the opposite side of the locking cam, the touch surface releases the other arm of the clutch lever so that it can pivot.
  • the latching cam leaves the latching recess and the retaining spring reaches the clutch lever in the release position.
  • Control engineering advantages result from the fact that the stop edge is the rear slope of the locking recess on which the stop shoulder rests flat.
  • a concept of the invention that is independent of its own is realized by providing a housing bracket that can be fastened to the door leaf and supports the clutch and the clutch actuator. Furthermore, there is a locking mechanism that can be plugged onto the housing bracket and that cooperates with an active extension with the clutch actuating element.
  • the housing bracket and the locking mechanism are overlaid by a hood-shaped housing cover that can be screwed from the inside of the door, the external turning handle coming into rotation with a coupling part when the housing cover is put on. After fixing the housing bracket on the outside of the door leaf, the locking mechanism to be actuated by the key card can be assigned to the housing bracket in a simple manner, and only by way of the plug connection.
  • the locking mechanism By fitting the housing cover and fixing it from the inside of the door, the locking mechanism is in a hiding position. It is possible to replace the locking mechanism if necessary after removing the housing cover.
  • the active extension of the clutch actuator When the locking mechanism is plugged on, the active extension of the clutch actuator is in the ready position for coupling, so that no further measures need to be taken.
  • the assignment of the locking mechanism is ensured in a simple manner by an insertion extension provided on the locking mechanism, which is inserted into an assigned insertion recess in the console when the locking mechanism is inserted which insertion point the locking mechanism can be pivoted into its insertion position while establishing the active engagement between the knitting extension and the coupling actuator.
  • This simple assembly can be carried out quickly and easily, so that, for example, a not inconsiderable time saving is achieved when several corresponding locking devices are attached.
  • the locking mechanism After the locking mechanism has been plugged on, it is secured in that locking arms are arranged on the housing bracket, between which the locking mechanism is held in its locking position.
  • the housing cover can then be placed in a convenient manner. This in turn is designed so that it is hooked with the housing bracket. The fastening screw securing the housing cover is therefore only used to secure hook engagement. Forces acting on the housing cover can therefore be safely absorbed.
  • the locking device designed according to the invention has a lock 1, which is fixed, for example, to a hotel room door 2.
  • the lock has a lock case 3 on the outside of the door, which has a rectangular floor plan and which has an external turning handle 4 at one end. With their help, an unillustrated trap can be withdrawn.

  • the key card has on both broad sides A and B elevations 10, 11 such that the magnetized areas 9 'of an insert 9 lie in the valleys of the profiling formed by the elevations 10, 11.
  • the elevations 11 on the broad side A there are longitudinal ribs, one longitudinal rib each being provided on the edge of the card. This results in a U-shaped cross-sectional shape of the key card 8, cf. in particular FIG. 3.
  • the other broad side B has the elevations 10 in the form of protruding wart-like projections. This means that the magnetic areas 9 'are always in the valleys of the elevations 10 and 11, respectively.
  • the elevations 11 designed as longitudinal ribs form stop edges 11 '. Upstream of these is an elongated incision 13, the end flanks of which form bevels 13 ', 13' '.
  • the lock case 3 receives a lock housing 14 in which a plate-shaped slider 15 is guided.

Openings 17 of the locking plate 16 are aligned in the locking position of the lock illustrated in FIG. 4 with bearing recesses 18 of the slide 15 designed as bores.
  • Magnetic tumbler pins 19 lie in the bearing recesses 18. It is not necessary to provide a tumbler pin 19 in each bearing recess 18 since the number, the position and the polarity of the tumbler pins 19 depend on the respectively coded magnetic areas 9 ′ of the key card 8.

  • the slide 15 cannot be moved from its basic position illustrated in FIG. 4, since the engagement of the tumbler pins 19 prevents this.
  • both the guide plate 20 and the anchor plate 21 are angled in opposite directions and form a gusset for the key card 8 to be inserted.
  • a tension spring 23 serving as a return spring is fixed at one end to a cross pin 24 of the lock housing 14.
