Definitions

  • a further trick lock is the coded type having an adjustable code mechanism, together with the safe-key with its disadvantages described above.
  • These locks are considerably complicated for making the opening of the locks difficult; however, the code mechanisms are located on the door and therefore susceptible to direct or indirect observation.
  • the number of code combinations is rather restricted; additionally, the coder is easily accessible and can be passed through quickly, while the normal manipulation with it is rather slow.
  • trick locks are provided with coding devices which are brought into operation by moving the key, or by electric impulses; even these are not entirely secure because the movements and the click of the key, as well as the electric impulses, are susceptible to direct or indirect observation.
  • Another disadvantage is their slow and rather difficult locking and unlocking.
  • a mechanical coded trick lock wherein there is a magazine (1), whose base has a'smaller or a greater number of holes -in which the pins (7) are placed, which pins are supported by springs (12) whose other ends lay on the grating
  • a coding block is mounted, including an upper matrix (3), a lower matrix (4) and a grid (6), located between the two matrixes.
  • the slits of the grid (6) are narrower than the diameters of the working cylinders (8) and wider than the diameter of the necks of the same cylinders.
  • the key (13) is preferably a plate with punched holes, forming a code combination.
  • the present invention solves many problems arising from the disadvantages of the locks of the prior art.
  • the key hole is a thin slit of 0.05 to 0.5 mm. into which it is not possible to fit a forged key or other instrument.
  • the lock is supplied with an unlimited number of cylinders n, forming 2" combinations.
  • the cylinders have double-direction action and the possibility to fix them in final position with various substances makes it impossible to unlock them.
  • the active parts of the lock (the cylinders) are preferably of plastics, which prevents an undesirable unlocking through contemporary scientific methods. Manipulating with this lock is extremely easy and quick. Rapid change of code combination is possible.
  • FIG. 1 is full-view illustration of the lock.
  • FIG. 2 is a sectional view along the line A--A of FIG. 1
  • FIG. 3 is a sectional view along the line BB of FIG.
  • FIG. 4 is a sectional view along the line CC of FIG. 3.
  • Pro. '5 is asectional view along the line 13-1) of FIG.
  • the lock consists of a magazine (1), a cap (2), an upper matrix (3), a lower matrix (4), a grating (5), a grid (6), pins (7), cylinders (8), springs (9, 11, 12), a key (13) and a button (14).
  • the magazine (1) is a box with a base supplied with a smaller or greater number of holes. In the hollow space of the magazine pins (7 are placed on a spring (9), a pin in each hole, so that they do not stick out below the base. Each pin has at its middle a flange on which the springs (9) rest.
  • the upper matrix (3) and the lower matrix (4) each have, respectively, as many holes as the magazine.
  • Each hole of the lower matrix (4) has a bottom and each hole of the upper matrix have a narrowing.
  • the two matrixes are assembled to each other below the magazine. Between the two matrixes, in the hollow space of the upper one the grid 6 is placed, which can move longitudinally for about 3mm.
  • On the base of the magazine there is a channel and when the .matrixes are assembled a slit (10) is formed therein,
  • the unlocking is done as follows: the punched tapekey (13) is placed in the slit (10) between the magazine (1) and the upper matrix (3), so that the punching of the key should fit to the punching of the magazine (I). As illustrated in FIG. 4, there may be 3 such holes.
  • a button (14) or a mechanism a lever is driven which exercises pressure on the grating (5), which through the spring (12) pushes those pins only below which there is a hole in the key.
  • the pins push only the respective cylinders (8), and thus the necks of all the cylinders move to a position exactly in the plane of the grid (6) which on its turn can move and set free the blocking mechanism.
  • the reverse process of locking is performed by setting free the grid and the spring (9) push the pins (7) back to the initial position, after which they key (13) can be taken out.
  • the lock can be used for various boxes, boards, desks, room doors, steel and fire-proof safes, automobiles, carriages, airplanes and other uses apparent to the art-skilled worker. It can be used either by itself or as an additional lock brought into operation by the key of the chief lock, after the code plate (13) has been inserted.
  • a mechanical codedtrick lock wherein there is provided a magazine having a base with a plurality of holes and having placed therein pins, said pins being supported by springs whose opposite ends lay on a grating, and wherein under said magazine a coding block is mounted, including an upper matrix, lower matrix and the grid located between the two matrixes, said plurality of holes of the coding block containing cylinders supported by the springs whereby the mechanical coded trick lock is brought into operation by inserting into it a key.
