Definitions

  • the invention relates to a security lock with the features of the preamble of independent claims 1, 4 and 6.
  • Such security locks are known.
  • the lock bit of these known security locks can be rotated about its axis with the help of the key. Apart from this rotary movement, the lock bit is rigid. In particular, it cannot be moved or pivoted in the radial direction. Therefore, in the prior art, the recess must also tangibly extend into the fastening part of the housing of this known security lock, in order to make room for the rotary movement of the locking bar.
  • the associated material weakening of the housing represents a tangible security risk because unauthorized persons can easily break through the housing at this weak point, which runs approximately in the center, with the aid of a suitable tool, which then creates free access.
  • the invention avoids these disadvantages. It is based on the task of proposing a security lock with the features mentioned at the outset, which is distinguished by a noticeably increased security.
  • the characterizing features of claim 1 serve to achieve this object. Accordingly, the recess in the housing practically only extends in its cylindrical part, because namely the actuating pin which actuates the bolt can be moved in and out in the radial direction. In its actuated position it is pressed outwards by the spring until it stops and can then carry out its usual actuation of the striking plate or bolt. If you turn the cylinder further with the help of the key and thus also via the pin housing, the head finally comes to rest on the control cam, which runs in such a way that it moves the actuating pin into its inactive position from the outside inward with a further rotary movement leads.
  • the head or the free end of the pin then passes over the now filled part of the cylindrical housing part, where it assumes its inwardly displaced position, in which it practically does not protrude beyond the diameter of the actual locking cylinder. If you turn it further, the guide curve recedes again, so that the actuating pin is finally guided outwards into its active position again by the spring. This movement can be carried out in both directions of rotation, and also from both sides of the door lock.
  • the housing with its locking cylinder protrudes a certain distance over the door, so that the housing can be broken out with a suitable tool.
  • the housing has a cross-sectional weakening at at least one end, preferably at both ends. A burglar is now attacking with pliers or another suitable tool at the protruding end, the housing breaks off in the area of the cross-sectional area, which therefore forms a predetermined breaking point. Then there is no longer a housing part and the lock can no longer be removed.
  • pin housing On both ends of the pin housing, slot-like recesses are provided, into which the key is inserted at one end or the other to actuate the key, so that the pin housing and thus also the actuating pin can then be rotated.
  • a spring-loaded pin is inserted into the inner end face of at least one of the locking cylinders, which pin is opposite a recess in the pin housing. As a result, the pin housing is locked in its correct position, so that the lock can be operated with the key.
  • the locking bit is radially displaceable, specifically via a control cam attached outside the locking cylinder.
  • a control cam attached outside the locking cylinder.
  • a second, but still more preferred embodiment of the invention is characterized by the characterizing measures of claim 4 to solve the problem of the invention.
  • the disadvantageous predetermined breaking point in the central part of the housing is avoided because the housing is sufficiently stable in this area due to a noticeable reduction in the size of the recess, so that it no longer breaks when attempting to break in.
  • the lock bit is moved by a suitable guide so that, despite this filling of the recess, it can rotate through a full angle, in which case it is retracted into the profile of the locking cylinder in the region of the recess while it is in the engagement region with the recess of the
  • the striking plate protrudes so far that the striking plate can be actuated (opened or closed).
  • the necessary retraction or extension of the locking bar into the profile of the locking cylinder or out of it can be done in several ways, for example by a displacement essentially in the radial direction, or also by a pivoting movement. It is preferred if, according to claim 7, the locking bit is guided and pivotally held in a recess in the pin housing in a spring-loaded manner.
  • a very important embodiment of the invention is characterized according to claim 6, characterized in that the housing has a cross-sectional weakening at at least one of its ends. Even if the case is a bigger one Has recess according to the prior art can be prevented by these measures, if necessary, that the housing breaks in the middle in the event of a break-in attempt, rather it will then break there with a corresponding design of the cross-sectional weakening at the end of the housing, which in turn prevents a break-in attempt .
  • the lock bit is pivotally held in the recess of a lock bit housing, care must be taken to ensure that this pivotable lock bit becomes active both when closing and when opening the lock.
  • Such a security lock should be able to be closed from both sides, ie from the inside and from the outside of the door. It is therefore necessary to ensure that only the pair of control cams that is now required becomes active during the respective closing movement.
  • claim 11 proposes a structurally simple and particularly space-saving solution, which ensures that when closing from the outside the outer lock cylinder is coupled to the lock cylinder and these two coupled parts move relative to the stationary inner lock cylinder, which then causes the relative movement between the Pins and the control curves.
  • the security lock is actuated from the inside, the situation is reversed, ie the inner lock cylinder is then coupled to the lock bit cylinder and the two control cams of the outer lock cylinder, which is stationary, become active.
  • the features of claim l5 also ensure that the profile channel can be made with relatively simple tools, because it consists of a substantially rectangular profile, which receives its individuality in that the profile strips according to claim l4 are used at predetermined points.
  • the profile strips can have hooks which also prevent the profile strips from being pushed out of their bores.
  • the bores can also be designed as blind bores, which also effectively prevents unauthorized sliding of the profile strips out of their bores.
  • the housing 1 accordingly consists of a cylindrical housing part 2, on the underside of which a fastening part 3 of the housing connects.
  • the fastening part has an essentially square cross section with a rounded underside. Both parts 2, 3 are of approximately the same length.
  • Approximately in the middle of the fastening part 3 runs a threaded bore 4 transversely thereto, via which the housing 1 can be fastened to the housing of the actual lock with the aid of a threaded bolt 5, as is known per se. See also FIG. 2.
  • an essentially cylindrical, continuous bore 6 is created, into which locking cylinders 7 are inserted from the two end faces. These are held by locking rings 8.
  • a recess 9 is provided approximately centrally in the cylindrical housing part 2. In Fig. 5 it is indicated that this recess 9 has extended far into the fastening part 3 in the prior art described at the outset. This is the extension 9a of the recess 9.
  • a peg housing is inserted into the recess 9, which is shown in detail in FIGS. 7 to 11.
  • the pin housing consists of a right plate l0 and a left plate ll. Pins l2 are provided in the left plate 11, which engage in corresponding holes l3 of the other plate. This fixes both plates to each other.
  • a radial guide l4 is formed between the two plates, in which a locking bit l5 designed as a pin can be moved radially.
  • a compression spring l6 At the inner end of the locking bar there is a compression spring l6, the other end of which is supported on the housing.
  • An extension l7 serves as a stop to limit the displacement path of the locking bar l5 along its guidance.
  • the free end of the locking bar is designed as a widened head 18, the top of which has a circular profile. The pin is inserted in the guide against rotation via the extension l7.
  • slots 19 are provided, into which the key for actuation engages.
  • Fig. 2 shows that in the position shown in this figure, the head l8 of the locking bar engages in a recess in a striking plate 20, so that when the cylinder and thus the locking bar l5 rotate in the direction of arrow 2l, the striking plate 20 in the direction the arrow 22 is moved. This unlocks the lock, for example.
  • the head 18 comes to a guide curve 23 of a guide part 24, which holds the pin at its Moves further rotation inwards until the pin and its head no longer protrude beyond the locking cylinder 7.
  • This guide function is performed in the lower part in FIG. 2 by part 9a of the housing. If the cylinder is turned further, the pin moves outwards again. In other words, he carries out a radial movement in the direction of arrow 25.
  • grooves 26 running all around are provided, which represent a cross-sectional weakening of the housing.
  • the housing part 2 has on its top side of the recess 2 widenings 27 of the recess so that the pin housing can be inserted into the housing l.
  • FIGS. L2 and l3 show that a spring-loaded pin 28 is inserted into one of the lock cylinders 7 and engages with its tip in a corresponding recess in the opposite plate 10, 11. As a result, the pin l5 is locked in the position shown in FIG. 2, so that when the key is inserted into the lock, it immediately assumes its correct position.
  • FIG. 14 shows that a lock bit housing 3l with a receptacle 32 is provided for partial locking bars 33 and 34. This part-closing Beards are also shown in FIGS. 15 and 16 in detail.
  • Both part-beards have through holes 35 to form a pivot axis.
  • they are profiled essentially in a T-shape, but with an asymmetrical arrangement of the crossbeams.
  • Their heads 36 have a circular cylindrical outer surface.
  • a leg spring 37 is inserted into a recess in the receptacle 32. The leg spring is pushed onto an axis which is held in a bore 38.
  • the legs 39, 40 of the leg spring each rest on one side of the partial beards 33, 34. See in particular FIGS. L7 to l9.
  • the bias of the spring is such that the partial mustaches are biased downwards by the legs of the spring in the view of Fig. to the mounting part 3 of the housing.
  • the partial locking beards 33, 34 are identical to one another. In addition to the through hole 35, they have a projection 4l.
  • a corresponding circular recess 42 is provided at the other end of the partial locking ridges, into which the tip of the elevation 4l of the other partial locking ridge is inserted.
  • the recess 42 is open towards the edge.
  • a sleeve 43 is inserted through the through hole 35, in which a locking pin 44 is inserted.
  • the sleeve forms the swivel axis for the relevant partial locking beard and the pin 44 engages with its tip in the inactive position of the two partial locking beards shown in FIG. 17 in a recess 45 of the other partial locking beard.
  • This recess 45 is arranged in the middle of the recess 42.
  • a further locking pin 46 can be provided, which is then inserted into a through hole 47 in the housing 3l and which also engages with its tip in a recess 48 corresponding to the recess 45 of the partial locking bit concerned.
  • FIGS. L7 to l9 now show the actuation of the safety lock during the opening process.
  • Fig. 17 shows the starting position, in which the two part-beards 33, 34 point down to the fastening part 3 of the housing l. They lay their heads on the upper wall of the fastening part 3.
  • the leg springs 39, 40 tension the partial closing beards downwards, i.e. in the direction of the central axis of the fastening part 3.
  • Fig. 18 shows the situation after the key and thus the lock has been turned through an angle of approximately 90 ° in the direction of arrow 49. It can be seen that the partial locking bit 34 has been pivoted outwards by the spring 37. In itself, the partial locking bit 33 would have been pivoted outwards by the spring. However, this is not possible, because in this angular position the locking pins 44, 46 engage with cams 50, 5l with their tips in the corresponding recesses of this partial cam 33 and also hold it in its inactive position against the force of the spring 37. The shape of the control curves 50, 5l can best be seen in FIG. 20.
  • control curve 50 extends over an angle of somewhat less than extends 180 ° and has a smaller radius than the control curve 51, which similarly also extends over an angle of somewhat less than 180 °.
  • Both control curves are designed as elevations of a control plate 52 (see Fig. 2l). The control cams thus cause the pins 44, 46 to be pressed into the recesses 45, 48 as soon as the outer ends of the pins 44, 46 ride on the control cams.
  • the partial lock bit 34 is also held in the position shown in FIGS. 18, 19 against the resistance of the bolt 20 because its trunk rests on the widened head 36 of the other partial lock bit 33.
  • the second closing process is carried out analogously, for which the lock is first turned clockwise to that in Fig. L8 shown must rotate back until the head of the partial lock bit 34 active for the locking process engages in the adjacent recess of the striking plate 20.
  • the other partial lock bit 34 is activated.
  • the lock is turned clockwise, the partial cam 33 then being activated, in a manner analogous to that described above.
  • the inactive partial locking bit 33 is locked by the pins 44, 46 and the projection 4l and held in its inactive position.
  • Fig. 14 also shows one of the clutches with which the lock bit housing 3l can optionally be rotatably coupled to the adjacent locking cylinder or the adjacent control plate 52. It should be noted that such a coupling is also provided on the left in FIG. 14; it has only been left out for clarification.
  • the coupling consists of a coupling piece 54 with an axial pin 55.
  • the pin 55 is inserted into a corresponding bore 56 in the housing 3l.
  • a corresponding receptacle 58 is formed in the control plate 52 (see FIG. 20). It should be mentioned that the control plate 52 is inserted into a corresponding receptacle 59 of the adjacent locking cylinder 7 in such a way that the two parts 52, 7 are connected to one another in a rotationally fixed manner. Cf. see Fig. 22.
  • both parts 3l on the one hand and 7, 52 on the other hand can be rotated relative to one another, so that the control cams of this coupling piece then take effect.
  • the coupling piece 54 is pushed out of its receptacle 57 by an appropriate amount, approximately by half its thickness, by inserting a key into the profile channel, the two parts 3l on the one hand and 7, 52 on the other hand are thereby coupled in a rotationally fixed manner.
  • the key channel 60 for inserting the key is formed by means of profile strips 6l, which are made of hardened steel.
  • the profile strips have a simple profile, preferably a circular profile with attached Rectangle.
  • a hook-like extension 62 can be provided, which prevents the profile strips from being pulled out towards the front. It can be seen that the key channel 60 has a rectangular profile and can therefore be produced using simple machines. Several of the profile strips 6l protrude from the side with their rectangular extensions into the key channel and thus form the actual key channel.
  • the bores for the profile strips in the cylinder core are preferably designed as blind bores in such a way that the profile strips are not visible from the front, so that the viewer has an undisturbed surface appearance. See pos. 66 in Fig. 22. This figure also shows how the hook 62 is anchored to the back of the cylinder core.
  • Fig. L5 shows that the outer ends of the pins 44 lie on a larger radius than the outer ends of the pins 46.
  • the pins 44 therefore cooperate with the control curve 5l located on the larger radius and the pins 46 with that on the smaller radius control curve 50.
  • control plate 52 has an annular shoulder 68.
  • Fig. 26 shows very clearly that there the upper lock cylinder 7 is not coupled to the lock case housing 3l because the coupling piece 54 is located entirely in the receptacle in the lock cylinder 7. In the lower part of FIG. 26, however, the other coupling piece 54 is located in the receptacles of both parts 7, 3l, so that these two parts are coupled to one another.
