Definitions
- the invention relates to a magnetic card lock with key card according to the preamble of the main claim. 5
- Magnetic card locks with key cards have been known for a long time.
- DE-OS 37 02 730 discloses a magnetic card lock with permanent magnets arranged in the key card, the position and polarization W of which form the key secret.
- the basic structure of a magnetic card lock is evident from European patent application 242 142, the lock having an insertion slot for a key card designed as a magnetic card.
- the lock has a 15 slidable slide into which the magnetic card can be inserted up to a first stop position. If the magnetic key card is correctly coded, this slide can be displaced by an actuation path up to t into a second stop position by further pushing the magnetic card into the lock housing. This relocation results in the release of the locking mechanism.
- the interrogation division, magnetic tumbler pins of the lock device are moved by interactions with the permanent magnets of the key card assigned to them. A key card with the appropriate key secret can then be shifted to a second stop position, the release position.
- the invention is therefore based on the object of designing a generic key card in such a way that a visual display of the locking mechanism position is provided with simple means.
- the position of the lock mechanism can be determined at any time. If the key card j e is first inserted into the magnetic card lock into the first stop position, the interrogation position, then in addition to the first partial surface there is also the second partial surface, which, for example, to stand out visibly from the first partial surface, is one of the first partial surface
- the locking position (query position) is immediately recognizable by the visibility of the second partial area. A user can also determine from a distance that the locking mechanism is not released. To release the lock
- the user advantageous training sets the first sub-area in the direction of insertion into a tapered section.
- the user receives information about the correct insertion direction of the key card.
- the tip of the first partial area lies approximately on that transverse line of the key card which corresponds to the release of the key position when the key card is withdrawn. This provides a visual display of the path by which the card has to be pulled out until the lock can no longer be actuated, * this path being greater than the actuation path.
- a further embodiment of the key card provides for the second partial area to be designed as a strip, the width of which corresponds to the actuation path, and beyond this strip, a third, optically separated partial area t5 which is approximately full when the key pull-out position leading to the release is released ⁇ fills the gripping opening. This also visually indicates the cancellation of the release of the lock.
- the second surface area which indicates the interrogation position of the lock, can have gussets which extend on both sides next to the first partial surface on the longitudinal edges of the key card, so that they are exposed in the first stop position and in the second stop position. 5 position are largely covered by the key card insertion rails.
- the second surface area can also have arrows pointing in the direction of insertion, which ends in the interrogation division with their tips in front of the front edge of the gripping opening. This provides the user 0 with additional information to further insert the key card inserted in the interrogation section into the lock to release the locking mechanism until the second stop position.
- An important advantage of the invention lies in the fact that it is possible in this way without having to change existing locks, to provide this subsequently with a visual display, the key card being used in addition to the function of carrying the key secret as a kind of dipstick to indicate the position of the slide inside the lock and thus its locking mechanism position.
- 1 is a magnetic card lock with magnetic card in a perspective view
- Fig. 2 is a key card
- FIG. 6 shows the section through a magnetic card lock according to line VI-VI in FIG. 4, but without a key card inserted
- Fig. 9 as Fig. 7, but in the release position with 5 key card position at the moment before Cancellation of the release position by pulling out.
- the key card 8 shown in FIGS. 1-5 has a region 100 which is clearly visible.
- This first partial surface 100 is preceded by a second partial surface 101, which extends from one longitudinal edge across the card surface to the other longitudinal edge, interrupted by a tapered section of the first partial surface 100.
- the upper edge 102 of the second partial surface is arranged such that As shown in particular in FIG. 5, it is aligned with the front edge 106 of the gripping opening 107 when the key card is inserted up to the release position. In this position, the rotary knob 4 is due to a displacement of the coupling sleeve 46 with the
- the gussets 108, 109 of the second partial surface 101 are arranged on both sides of the first partial surface such that they are visible in this position and largely through the insert rails when the key card is inserted until the release position
- the base line 103 of the second partial surface is positioned such that it is aligned with the end edge 106 of the gripping opening 107 when the key card is inserted up to the query position.
- the second partial surface 101 has arrows 110, 111 on both sides of the section of the first partial surface 100 which interrupts it and which point in the insertion direction and end with its tip in front of the base line 103.
- the tip 104 of the section of the first partial surface 100 which tapers in the insertion direction of the card is in alignment with the end edge 106 of the gripping opening 107 when the key card 8 is removed the release position of the lock is canceled.
- the rotary knob 4 is then uncoupled from the actuating mandrel 49 by moving the coupling sleeve 46.
- the magnetic card lock 1 shown in FIGS. 6-9 has a lock case 3, which is fixed on the outside of the door and has a rectangular outline, which has an external turning handle 4 at one end, with the aid of which a bolt or a latch, not shown, can be withdrawn.
- the lock case 3 is provided at the other end with an insertion slot 7 for a regionally magnetized key card 8.
- the lock case 3 receives a housing 9 which has a cover 13 which is fixed to the housing 9 by means of screws 16.
- a slider 17 made of plastic and made in the form of a plate.
- the guide surface opposite the cover 13 forms a perforated plate 18 made of brass, which is inserted into the housing 9 from the cover side.
- the holes 20 of the perforated plate 18 are aligned in the position (locking position) of the lock 1 shown in FIG. 6 with corresponding bearing recesses 21 of the slide
- Magnetic locking pins 22 lie in the bearing recesses 21. It is not necessary to provide a tumbler pin 22 in each bearing recess 21, since the number, the position and the polarity of the tumbler pins 22 depend on the respective locking secret of the lock 1.
- the perforated plate 18 On the perforated plate 18 is a copper baffle 23, which is opposite an anchor plate 24. The latter will held in position by compression springs.
- the anchor plate 24 consists of ferro-magnetic material. The anchor plate 24 thus attracts the magnetic tumbler pins 22, as a result of which they engage 5 in the holes 20 of the perforated plate 18. In this position, the slide 17 cannot be shifted from its basic position illustrated in FIG. 6, since the engagement of the tumbler pins 22 in the perforated plate 18 fixed to the housing prevents this.
- Both the anchor plate 24 and the guide plate 23 adjoin the insertion slot 7 of the lock box 3. Their opposite wall surfaces form the key card slot 30. 5
- a tension spring 33 serving as a return spring is fixed at one end to a cross pin 34 of the cover 13. The other end of the tension spring 33 engages on a projection 35 of the slide 17. As a result, the slide is in a basic position limited in FIG. 6
- the bevel 38 of the nose 36 of the slide 17 is designed in the same direction. It engages on the inclined surface 40 of a web 42 of a tongue 43 made of spring material. The latter is positively embedded on 5 of the top of the cover 13 and fixed with the cover screws 16.
- the inclined surface 40 of the web 42 is formed by a bend which is directed away from the bevel 38 and extends in the immediate vicinity in the basic position, cf. Fig. 6.
- the tongue 43 engages with its fork-shaped free end 44 in an annular groove 45 of a coupling sleeve 46.
- the latter is internally toothed.
- cf. Fig. 6 includes the clutch sleeve se 46 exclusively a gear 47.
- This continues in a bearing sleeve 48 with the square pin 49, which is coupled to a door lock.
- the bearing sleeve 48 is rotatably supported in a lock case base plate 50.
- the bearing sleeve 48 is secured against being pulled off by a radially outwardly directed collar 48 'provided on it, which is supported on the inside of the lock case base plate 50.
- a gear 51 is located opposite the gear 47.
- Both gears 47, 51 have the same toothing and are adapted to the inner toothing of the coupling sleeve 46.
- the gear 51 is firmly connected to the external turning handle 4.
- a central pin 52 is used to stabilize the position of the gear wheels 47, 51, but does not influence the rotatability of the gear wheels 47, 51.
- the length of the gearwheel 47 corresponds approximately to that of the coupling sleeve 46. In the uncoupled position, the inner end face of the coupling sleeve 46 ends in front of the facing end face of the gearwheel 51 Square pin 49.
- the slider 17 can be locked in its forward position (release position).
- Resilient locking cams 70 which are formed by locking hooks 41, serve for locking transversely to the slide displacement.
- the latter are rotatably mounted about an axis 39 in the slide 17.
- the latching hooks 41 projecting into the card insertion path have been acted upon, these being correspondingly displaced in the transverse direction in such a way that the latching hooks 70 then protrude into openings in the cover 13.
- the slide 17 is displaced against the force of the tension spring 33.
- the locking cams 70 undercut the resilient stop of a leaf spring 71. As soon as the locking cams 70 have completely undercut the spring 71, these are fixed (FIG. 8). The slide 17 is thereby locked against relocation.
- Uncoupling requires the key card 8 to be withdrawn.
