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 allowing the temporary storage of various objects by the public.
  • the invention solves this problem by making it impossible to reconstruct the coding combination without having a special device which can only be accessible to specialized personnel and which can be stored in a safe or the like. .
  • the coding device for furniture locks and the like and for locating said coding comprising a bolt which can be operated by a shaft from a button external to the cabinet is characterized in that it includes coding buttons with step-by-step operation for also step-by-step driving of coding wheels each having a notch and a magnet, said coding wheels being arranged around a swash plate comprising fingers which have entered the notches of the various coding wheels during the '' establishment of 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 operation of a shaft leading to the erasure of a dog and the pivoting of the swash plate so that the coding buttons freely drive the coding wheels without it being possible to retract the bolt then maintained by the dog and a finger of the swash plate, sleeves being provided near the coding wheels for the installation of a magnetic detector so that the position of the magnet of each coding wheel can be identified with the aid of said detector in case of forgetting to the
  • Fig. 1 is a schematic elevation, partially broken away, of the coding device for a lock according to the invention.
  • Fig. 2 is a section taken substantially along 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 comprises.
  • Fig. 5 is a sectional elevation of the device member allowing the identification of the code.
  • the device illustrated by figs. 1, 3 and 4, comprises a housing 1, for example made of folded sheet metal, inside which is arranged a compartment 2 for a coin-operated device designated as a whole by the reference 3.
  • the coin device not directly forming part of the invention is not described in detail in the following but is simply illustrated to show the position occupied by a coin 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 has two branches 15, respectively 16.
  • the branch 16 is used to lock a bolt 19 when the latter is released as illustrated in FIG. 3, position in which said branch 16 enters a notch 20 in said bolt, which is shown in FIG. 3.
  • the bolt 19 is on its side moved by a lever 17 mounted on an operating shaft 18 actuated from outside the housing 1.
  • the housing 1 contains a guide plate 21 which is fixed thereto and in which notched openings are made 22.
  • the number of notches 23 is normally ten to correspond to a graduation formed for example for the numbers 0 to 9 carried on a plate front panel 24 through which pass coding buttons 25 which can be advanced step by step from one notch to another by means of balls 26 (fig. 2) which contain and which are pushed by springs 27 into successive notches 23.
  • the coding buttons 25 have a core or shaft 28 mounted in a bearing 29.
  • the bearings 29 are formed by coding wheels 30 which can be driven by balls 31 pushed by springs 32.
  • the balls 31 and the springs 32 appear at the fig. 1 and are shown diagrammatically in FIG. 2. They can be angularly offset relative to the 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 coding wheels are each provided with a small magnet 35 disposed opposite the guide plate 21 which is provided with sets of metal studs 36 disposed opposite each coding button as illustrated in FIGS. 1 and 4.
  • the device comprises a swash plate 37 mounted on an axis 38.
  • the swash plate is provided with four oblong slots 40.
  • the four oblong slots 40 allow the passage of four sleeves 39 which are an integral part of the guide plate 21.
  • the shape of the swash plate is chosen so that it has an off-center part 37a 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 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 located in the position of fig. 1 can, by acting on the coding buttons 25, compose a four-digit code of his 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 measurement, which prevents a user who does not know the combination displayed from bringing in the bolt by acting on the shaft 18.
  • the user recomposes the combination so that the position of the notches of the coding wheels again corresponds to that of the fingers of the swash plate which rocks by gravity to occupy a position which authorizes, via the dog, the retraction 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 collective furniture, clothing lockers, locker room doors. In these applications, the user sometimes forgets the combination created.
  • This member comprises a head 42 containing a micro-switch 43 with flexible blades.
  • the head 42 is also provided with a keying device 44 whose male shape corresponds to a female shape given to the sleeves 39 or to a part of these.
  • the conductive blades of the microswitch are connected to a diode 45 and to batteries 46 placed 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 into a first sleeve 39, then the corresponding coding button 25 is rotated step by step. This has the effect of bringing the magnet 35 of the corresponding coding wheel into a position for which the magnetic field of this magnet can polarize the two blades of the microswitch 43 which then close the electrical circuit of the coding detector device.
  • the purpose of the metal studs 36 is to channel the magnetic field of each magnet 35 and to prevent its dispersion. When the magnetic field is maximum, the blades of the microswitch 43 are closed and, consequently, the diode 45 is lit.
  • the identified position thus corresponds to a first position of the coded combination.
  • the same procedure is carried out for the other coding wheels by acting on their respective coding button and by introducing the head 42 into the corresponding sleeves.
