Definitions

  • the invention relates to a lock that can be used to lock doors and windows used in buildings and in other places, which has an improved locking system due to which the lock can be produced in many different forms - mortise lock, screw-on lock, both small and big - and beside this the locking system can be provided with a rather high number of variations as compared to the ones already known, even in the case of small sizes.
  • Chubb system safety locks that is locks operated with keys with one or two key-bits.
  • these in respect of the number of variations only those meet the safety requirements which extend in the direction of the axis of the key (considering a key put in the lock), that is their plate is thick, and they are rather extended in the other two directions, too.
  • the disadvantages resulting from this are well-known (more material, more cost, a bigger indented hole in the door in the case of indention, which weakens the door, etc.)
  • the task to be solved with the invention is to make a small, safe and otherwise high-strength lock with a high number of varieties, and an improved locking system needed for it.
  • the number of variations is usually especially low as compared to locks operated from one side, e.g.: safe locks.
  • Another task to be solved with the invention is to make the levers in a way that a small locking system, in respect of the width and height of the striking plate, and by this small locks can be made.
  • the invention relates to a locking system of increased safety, which has a striking plate created by a bottom plate, cover plate and front plate, or similar to it, in which - according to any of the already known ways - there is a bolt, making linear motion possible, protruding from the striking plate, connected to the levers in co-operation with it, made in a way that it determines the closed and open positions of the bolt, and on the striking plate there are keyholes made for a turnable key in co-operation with the bolt, realising rotating cyclic mechanism with the levers, and in the striking plate there is a disc provided with at least one tooth, embedded in a way allowing concentric rotation with the keyhole, suitable for taking the key.
  • the stem of the keys (whether they have one or two key-bits) used for the known locks is cylindrical, and for this reason they are expensive to produce, because the key stem cross section which is thicker than the key-bit or the key-head can only be made by casting or by difficult compression.
  • Figure 1 shows a lock according to the invention, with its cover plate taken off, at a scale of 1 : 1, in the basic open position of the lock,
  • Figure 2 shows the lock as in drawing 1, in the A-B section shown there
  • Figure 3 shows the lock according to drawing 1, with the key inserted, in section, in the position after the first quarter turning of the key in the course of the locking process, and in the position after the last quarter turning of the key in the course of the opening process
  • Figure 4 shows the lock according to drawing 3 in the same position, in section C-D shown there
  • Figure 5 shows the disc shown in the previous drawings, axonometricly, at a scale of
  • Figure 6 shows a part of the key, also axonometricly, positioned axially against it
  • Figure 7 shows a part of the lock in a position according to the A-B section (drawing
  • Figure 8 shows another lock made with a lever system different from the one shown in drawings 1-4, in the same way as in drawing 1,
  • Figure 9 shows section E-F shown in drawing 8
  • Figure 10 shows the lever according to another favourable construction shown in drawings 8 and 9, in a position as in drawing 8
  • Figure 11 shows a further favourable arrangement of the disc and the bolt in a position according to section E-F as in drawing 9
  • Figure 12 shows the bolt and the disc together, belonging to the newer lever system shown in drawing 8, the rest of the components have been removed, in a position of the disc, or the key that is not shown here, after one-eighth of a turn
  • Figure 13 also shows a disc, but unlike the above solutions, in a construction suitable for a key with one key-bit, in an axonometric view, at a scale of 1 : 1 used above,
  • Figure 14 shows a disc in axonometric view, at a scale of 2: 1, which has the same central cylindrical tongue as the one in drawing 13, but it is for
  • a lock 1 in basic position, its plate consists of a bottom plate la and a cover plate lb, and the latter one can be seen first in drawing 2.
  • the striking plate is closed with a front plate 2 characteristic of mortise locks, and the bolt-head 3 a of a bolt 3 is put through its opening.
  • the bolt 3 has got a disc-like bolt stem 3b inside the lock 1, as usual.
  • the lock 1 itself is made so that its overall dimensions are not bigger than those of the lock known in Hungary as Elzett 700, but rather it is less wide, which is made possible by its different internal structure.
  • This construction just like any of the other constructions shown in the drawings, is suitable for use in other locks, too, or for making locks constructed like other type of locks, with the same insertion dimensions.
  • the gate pin Id which is favourable fixed into the bottom plate 1 a, is also for driving the bolt 3 straight, so in this case there is also a slot 3d in the bolt stem 3b.
  • the lever 4 is continuously held against the gate pin Id with a spring 4b made in the normal way, attached to the bolt 3, supported against the pin 3e, fixed into the lever 4 at the bottom, or, in the given case it is held against the key-bit in a position stopped from above. It follows from this that the gate pin Id can be fixed onto the bolt stem 3b, and the bolt pin 3c can be fixed onto the bottom plate la by rearranging the window 4a in an appropriate way, and inside this the bolt pin 3 c could also be somewhere close to the bolt head 3 a or somewhere close to the end of the lock 1.
  • a disc 5 is embedded in the lock 1 in a turnable way.
  • a keyhole If is made for the key in the usual way, and for this a connecting hole 5a, the size of which suits the key-bit, is made on the disc 5.
  • the disc 5 is placed axially with respect to the keyhole If, the key inserted into the lock 1 can be turned around.
  • a new development in the case of this solution is the use of the disc 5, because in this way the number of levers on it can be increased, and it has a role in increasing the combinations and the number of variations that can be achieved in the lock 1.
  • connection between the key and the bolt 3 should be created at least on one place - if the bolt stem 3 b is in the middle of the striking plate, on its dividing line - so that this connection results in the progressing movement of the bolt 3 when the key is turned.
  • This is a possible arrangement of the bolt stem 3 b, but not the best one, because on the one side of the bolt stem 3b less than half of the inside dimension of the levers 4 perpendicular to the bolt stem 3b inside the striking plate remains, which can be dissatisfactory especially in the case of mortise locks.
  • the described construction also includes a key 6, which can be seen in drawings 3, 4, 6 and 7, to show how it fits into the disc 5, and to show that the key-bit 6a of the key 6, or in this case its key-bits 6a, are not equipped with parts serving the purpose of direct connection to the bolt stem 3b, and for this reason the complete width of the key-bit 6a is constructed to make connections with the levers 4.
  • Drawings 8-10 show another favourable construction which does not have the same variation possibilities as in the case of the turning levers 4 used in the previous drawings, i.e. that the levers 4 can be constructed in a way that they turn around a point fixed to the bottom plate la or the bolt stem 3b, that is around the bolt pint 3c.
  • the levers 4 are driven along a straight vertical line in relation to the bottom plate la.
  • the levers 4 can also be constructed in a way that they are driven along a straight vertical line with the help of channels made on the bolt stem 3b, on the basis of already known methods.
  • the moving of the levers 4 driven along the bolt stem, both with turning levers and levers driven straight, will be complex in relation to the bottom plate la.
  • drawing 11 is to show that in connection with the construction of the bolt stem 3b, the disc 5 can be placed not only beside the bottom plate la, unlike in the previous cases, so the teeth 5b can even point towards the bottom plate la.
  • drawing 13 The purpose of drawing 13 is to show that on the one part the disc 5 with one tooth 5b can also be used in locks where the key has one key-bit, and on the other part it shows that the central part of the disc 5 can also be made with a cylindrical extension 5c.
  • the cylindrical extension 5c provides the disc 5 with a further possibility of embedding, as it can be made so that it protrudes into the cover plate lb, the central part of the keyhole If extended for this purpose, on the other part with a channel 5d it is made in a shape and in a size suiting the stem 6b of the key 6, which has a circular section in this example.
  • the disc with an extension 5 c can be easily produced from a zinc casting or using powder metallurgy, unlike the disc shown in drawings 1-12, which can also be produced easily from a steel plate, by compression.
  • the disc 5 shown in drawing 13 it can be seen that the most important part of the tooth 5b is the protrusion at the outer end of the connecting hole 5a, but it does not exclude the construction surrounding the connection hole as in drawing 5.
  • the stem 6b of the key 6 is not cylindrical, but flat, and the connecting hole 5a of the disc 5 and the channel 5d in the extension 5 c is made to suit it.
  • the extension 5 c does not necessarily have to be there, because the key 6 can also be turned around in the widened out version of the central part of the keyhole If made in the bottom plate la and the cover plate lb, suiting this flat version of the stem 6b, but it is favourable to have it.
  • keys can be easily produced from a 2-3 mm thick plate, e.g.: from steel or brass.
  • the disc 5 occurs as an extra cost only once per lock, but it is counterbalanced by what you save when you have several keys.
  • the key 6 made with a flat stem 6b can also be used with a disc 5 which does not have a tooth 5b, mainly in the case of traditional locks.
  • the disc 5 can also be made so that it is driven by only the two ends of the extension 5 c, without its circular dimension, only with the part left around the connecting hole 5a.
  • Any version of the disc 5 can be positioned in its basic position in a known way, e.g.: with an arresting device.
