Definitions

  • the invention relates to a combination lock comprising tumblers which can each be displaced in a channel in a release part by means of an adjustable cam so that the release part can be released for motion at a certain cam position and thereby permit opening of the lock, which tumblers each consists of a split tumbler pin whose end piece has a length which is equal to the length of the channel in the release part.
  • Locks of this kind are used wherever there is a demand for a high degree of security in that the number of combinations can be made very large. This is obtained by a suitable choice of tumblers and corresponding code units.
  • Each lock unit is thus built of several code units which are more or less different due to their position in relation to each other relative to the release part and hence the tumblers.
  • the release part can be embodied as a longish body which can be fitted parallel to the upper surface of the lock housing whereby the individual pivotal code units can be enclosed and fitted opposite each a tumbler in the release part.
  • the lock can be coded when it is fitted by changing the angular position of the cam relative to the tumbler. This simplifies the manufacture of the lock, because the coding and the fitting is performed simultaneously.
  • the lock can be disengaged by a single longitudinal impact on the release part.
  • the drawing shows an example of an embodiment of a combination lock as it may be configured for being fitted in a bicycle lock with locking ring or locking arm.
  • the locking arm 1 On one side - the front - the locking arm 1 is provided with a number of channels 17, vide particularly fig. 7, extending in the transverse direction of the arm. Moreover, a number of teeth 2 with inclined side faces are formed on the back of the arm 1 against which teeth a number of click pawls 16 and locking pawls 12, 13 rest.
  • a pressure pin 18 is inserted in the channel 17, vide particularly figs. 2-4, the said pin being divided into two in such a manner that the length of the outermost portion corresponds to the depth of the channel 17 as shown in fig. 6.
  • These pressure pins 18 are all spring-loaded by implied springs 26, vide figs. 2, 6 and 8, which push the pins 18 out through the channel 17.
  • the click pawls 16 are spring-loaded in the same direction by means of implied springs 27, vide figs. 2, 6 and 8, and the locking pawls 12, 13 are impacted on by springs 28 as implied in figs. 3 and 4.
  • the rear of the one locking pawl 12 is provided with a downwards projecting pawl arm 25 being in engagement with a hole in a pivotally mounted further locking pawl 14, vide part. figs. 1 and 7, so that a movement of the locking pawl 12 causes a pivoting or turning of the locking pawl 14, as shown by the arrow in fig. 7.
  • the locking pawl 14 can for example disengage a not-shown fixed locking part.
  • the two locking pawls 12, 13 pointing forwards have different embodiments of their end surfaces for interaction with a bevelled locking groove 23, vide fig. 9 and a straight locking groove 24, see fig. 10, respectively, provided in the locking ring 21 which is disengaged when the locking pawls 12, 13 are carried backwards and out of engagement with the ring 21, as shown in figs. 9 and 10.
  • a pivotal unit 5 acting on the pressure pins 18 is on its outside provided with a cam 9 which can be swung towards the pin and push it into the channel 17, as shown in fig. 6. Where the cam 9 is turned away from this position, the tumbler springs 26 will push the pin out towards the cam shaft 8, as shown in figs. 2-4, whereby the pin 18 will bar the longitudinal displacement of the release arm 1. In this condition the lock will be locked.
  • the pivotal part 5 is constructed, as shown in figs. 2, 6 and 8, with a base 7 being provided with a number of fitting grooves 10 in which assembly pins 22 can be inserted. In the shown example there are eight grooves 10 evenly distributed along the periphery of the base 7. The base is moreover provided with a central upwards extending pin about which the cam shaft 8 can turn.
  • the shaft 8 is further provided with a click disc 6 with eight teeth.
  • a spring force 27 causes the click pawl 16 to engage with the spaces between the teeth on the click disc.
  • the pivotal code units 5 are all identical, and coding of each unit takes place during the actual fitting in the lock housing 19, 20. As shown by black triangles in fig. 1, each unit is differently orientated prior to being pressed into place in assembly pins 22. As implied at the top of fig. 5, each button 11 must hereby be turned a different number of clicks in order to unlock the lock, viz. one, three, four and six clicks, respectively, in the shown example.
  • the tumbler springs 26 and click pawl springs 27 may have different spring tensions which makes it impossible to determine the position of the cams 9. It will be an advantage to apply identical springs which, when fitted in holes or bores of varying lengths, will provide the required variation.
  • the code units 5 are identical as are the pressure pins 18, the click pawls 16 and the springs 26, 27. This makes production less expensive and enables an automated fitting of the lock.
  • coding can be varied by the choice between - in the shown example - eight different positions for one unit.
