Definitions

  • the invention relates to a coding device comprising a new device for locating said coding of locks for furniture, for example for locker room furniture, chests and the like for temporary storage various objects by the public.
  • the invention solves this problem by ensuring that it is impossible to reconstruct the coding combination without having a particular device that may not be accessible specialized personnel who can be stored in a safe or the like.
  • the device for coding and locating said coding for furniture locks and the like comprising a bolt operable by a tree from a knob outside the cabinet is characterized in that it comprises step-by-step coding buttons for also step-by-step drive of coding wheels presenting each a notch and a magnet, said coding wheels being arranged around a swash plate comprising fingers that got into the notches of the different encoder wheels when establishing a combination coded by rotation of the coding buttons with respect to a graduation of a front plate, the exit of the bolt by the maneuvering a tree causing the erasure of a dog and the swiveling of the swash plate so that the coding freely drive the coding wheels without it is possible to retract the bolt while maintained by the dog and a finger of the swash plate, sleeves being provided near the coding wheels for setting up a magnetic detector making the position of the magnet each coding wheel can be identified using said detector in case of forgetting the coded combination so as to find the combination.
  • Fig. 1 is a diagrammatic elevation, partially broken away, of the coding device for a lock according to the invention.
  • Fig. 2 is a section taken substantially along the line II-II of fig. 1.
  • Fig. 3 is a schematic elevation, similar to FIG. 1, illustrating a characteristic position of the device.
  • Fig. 4 is a schematic elevation, similar to FIG. 1, showing particular elements that the device.
  • Fig. 5 is a sectional elevation of the device member allowing the location of the code.
  • the device illustrated by figs. 1, 3 and 4, includes a case 1, for example in folded sheet, inside which there is a compartment 2 for a coin-operated device designated as a whole by the reference 3.
  • the device coin mechanism not directly part of the invention is not described in detail in the following but is simply illustrated to show the position of a piece of currency or other token 4.
  • the part 4 is provided to descend along a ramp of 5 to pass through a passage 6 in which it occupies at a time position 4, this piece, when released, falling to the position 4b .
  • a dog 9 whose function is described in the following is articulated on an axis 14 and comprises two branches 15, respectively 16.
  • the branch 16 is used to lock a bolt 19 when the latter came out as illustrated in FIG. 3, position in which said branch 16 enters a notch 20 of said bolt, which is shown in FIG. 3.
  • the bolt 19 is moved by a lever 17 mounted on a shaft maneuver 18 operated from outside the housing 1.
  • the housing 1 contains a guide plate 21 which is there fixed and in which notched openings are made 22.
  • the number of notches 23 is normally ten for correspond to a graduation constituted for example for numbers 0 to 9 carried on a front panel 24 by which pass coding buttons 25 which can be advanced step by step not from one notch to another by means of balls 26 (fig. 2) which they contain and which are pushed by springs 27 in the successive notches 23.
  • the coding buttons 25 have a core or shaft 28 mounted in a bearing 29.
  • the bearings 29 are formed by encoder wheels 30 which can be driven by balls 31 pushed by springs 32.
  • the balls 31 and the springs 32 appear in fig. 1 and are shown schematically in fig. 2. They can be angularly offset by compared to balls 26 and springs 27.
  • the coding wheels 30 also each delimit ten notches designated by 33 in fig. 1.
  • the periphery of the coding wheels 30 has for each of them a notch 34, 34 a , 34 b , 34 c ...
  • the encoder wheels are each provided with a small magnet 35 placed opposite the guide plate 21 which is provided with sets of metal studs 36 arranged in look of each coding button as illustrated in figs. 1 and 4.
  • the device includes a swash plate 37 mounted on an axle 38.
  • the swash plate is provided with four oblong lights 40.
  • the four oblong lights 40 allow the passage of four sleeves 39 which are part integral with the guide plate 21.
  • the shape of the swash plate is chosen so that it has an off-center part 37 a tending to make it rotate clockwise under the action of its own weight.
  • the swash plate is, moreover, provided with fingers 41 four in number to correspond to the number of notches 34, 34 a , 34 b ... This position is illustrated in FIG. 1 and, in this case, the coding wheels 30 cannot be driven by the coding buttons 25. In fact, the fingers 41 prevent this rotation but the coding buttons 25 can rotate since the balls 31 as well as the balls 26 (fig. 2) can go from one notch to another.
  • the user of the lock in the position of fig. 1 can, by acting on the coding buttons 25, dial a four-digit code of your choice.
  • the branch 15 of the dog is in the low position since the branch 16 is located in the notch 20.
  • the swash plate 37 can pivot, the fingers 41 then emerging from the notches 34, 34 a , 34 b ... of so that the coding wheels can be driven by the coding buttons of any measure, which prevents a user who does not know the combination displayed from bringing in the bolt by acting on the shaft 18.
  • the encoder wheels can be driven at the same time time as the coding buttons, the combination performed remains in memory.
  • the user redials the combination so that the position of the wheel notches again the coders correspond to that of the fingers of the plate oscillating which rocks by gravity to occupy a position which authorizes, through the dog, the re-entry of the bolt and therefore the opening of the lock.
  • the lock coding device described in the foregoing is intended to be used in particular in furniture communities, clothes lockers, doors cloakrooms. In these applications, it sometimes happens that the user forget the combination created.
  • This member comprises a head 42 containing a microswitch 43 with flexible blades.
  • the head 42 is also provided a key 44 whose male shape corresponds to a shape female given to scabbards 39 or a part thereof.
  • the conductive blades of the microswitch are connected to a diode 45 and to batteries 46 arranged in the body 47 which supports the head 42.
  • the body 47 can be removable if it is desired to be able to change the battery or batteries 46.
  • the head 42 is introduced in a first sleeve 39, then we rotate step by step the corresponding coding button 25.
  • This has the effect of bringing the magnet 35 of the corresponding coding wheel in a position for which the magnetic field of this magnet can polarize the two blades of microswitch 43 which then close the electrical circuit of the detector device coding.
  • the purpose of the metal studs 36 is to channel the magnetic field of each magnet 35 and avoid its dispersion. When the magnetic field is maximum, the microswitch 43 blades are closed and, by Consequently, the diode 45 is lit.
  • the identified position thus corresponds to a first position of the coded combination. It is done in the same way for the other coding wheels by acting on their button respective coding and by introducing the head 42 in the sleeves correspondents.
