"Locking with alphanumeric dial and different code number "

The invention relates to locking and built-in security locks which allow handling with an alphanumeric dial without a key. In French patent specification 694o33o, filed on November 24, 1969 in the name of the applicant Georges Pieddeloup the locking and unlocking positions are by means of cams in conjunction with gears powered rocker arm has been achieved. In the present invention, the gears are like Related to index cams, the pawls of these wheels replace and cancel the tilting devices, and simplify the system of mechanical construction and downsize the spatial extent of each code number component.

In the known devices of this type are previously, simultaneously or successively operating sequences with the Use of the dial required; their mechanical design limits the number of digits in the code number and the Versatility of certain switching mechanisms with the use of each digit element of the code number during one after the other The loading from the dial makes these systems vulnerable.

The device of the present invention consists of a drive plate 8, which by interposition a shaft 3 is positively connected to the dial structure 1, the unit being driven by the return spring 5 is held in the rest position and pressed against the abutment IB.

The driver disk 8 causes a pawl 9 held against the disk by a spring Io to tilt by one to support the system locking during operation of the dial existing longitudinal shaft 11. The disc 8 is arcuate in shape and parallel to the dial shaft 3 rotating drive shaft 12 equipped. A certain number are seated on the numeralshaft 3 coded gears. This number depends on the scope of the code number or the available Theoretically unlimited space.

The place value of each row of numbers of the code number is a function of the position of a gear 17 which by a by a spring 22 tensioned pawl 21 is held in its position. This wheel is frictional with a die

Retaining spring 19 receiving Pederkäage 18 connected. The spring cage 18 is penetrated by a shaft 2o which serves as an abutment in the initial position and is in engagement with a gear. This gear has a flatter, the index determining tooth, so that with the help of the spring cage the wheel can turn around the value of the Change code number.

The adjusting pawl 21 of the gear causes its tilting movement about the locking axis 11 that it is for the Unlocking position is located after the interpretation of the path length of the tilting movement over the flatter tooth. The cancellation command of the unit 25 retained by the spring 26 allows the clearance of the gear pawls to be released 21 and thus the release of all the gears held in the rest position by the springs 19. This cancellation command, combined with the opening command also comes into force in the event of incorrect handling. Each gear has a movable driver guide 15, which is triggered when the dial is relaxed with the aid of the spring 15 B, and the driving of the drive shaft 12 and the entry of a digit with a higher-level value for the following gearwheel is permitted. Each The gear wheel, which leaves its rest position, releases a movable counter bearing 13 which, under the spring pressure 13 B tilts and the driver guide 15 of the following gear is activated. This allows commands to be issued one after the other

for all gears of the code number. This ensures that the dial is replaced by one that takes place one after the other Enter the code digits in read order for unlocking to operate, with a single inappropriate place, one of the pawls is located in a protruding tooth and causes the locking. The inventive device can be used in all cases in which there is a lock or a Security lock with keys proves necessary, especially when the operating personnel on a must be limited to a certain number. There are possible applications for the invention for opening doors, protective covers, or for controlling breakers and other electromechanical systems Giving orders.

Claims (5)

- 5th claims; [1.) Device for locking or unlocking with the help of a Identification mechanism and handling with an alphanumeric dial, characterized in that that it has an alphanumeric dial that triggers a certain number of gears, the gears are in the starting position according to a certain number in their rest position, and that the Unlocking unit with the help of a dial of a place value that corresponds to the code number performs. 2. Apparatus according to claim 1, characterized in that the command using a simple dial in given the type of a telephone rotary dial. 3. Apparatus according to claim 2, characterized in that the dial is always consecutively in the same The order in which it is written must be used in order to create the entirety of the code number. 4. Apparatus according to claim 1, characterized in that the point of the code number is formed by a flatter Tooth on each gear is determined. 209824/0050 5. Apparatus according to claim 4, characterized in that a shifting of the gear with the help of its counter bearing the point of the flatter formed, also the Code number determining tooth changes. 6. Apparatus according to claim 1, characterized in that the adjusting pawl of the gear serves as a locking nose due to its tilting movement according to the height of the wheel tooth. 7. Apparatus according to claim 4, characterized in that the input movement of a gear is triggered with the help of a movable driver guide. 8. Apparatus according to claim 4, characterized in that while the gear leaves its rest position, it should be movable counter bearing, which tilts and activates the movable driver guide of the following gear, releases. 9. Apparatus according to claim 1, characterized in that the scope and importance of the code number are limited is only due to the space available. Io.Vorrichtung according to claim 1, characterized in that does not provide any other handling than the unlocking entered after the code number in the dial. 20982 4/0050 ~ ⁷ " 11. The device according to claim 1, characterized in that the movement to open or to cancel in the event of mishandling, the setting pawls of the gears are released, the latter becoming free and return to their position of rest. 209824/0050 Lee r be e
