Definitions

  • the invention relates to a burglary alarm for a bicycle, installed inside the bicycle frame.
  • the crank of the bicycle includes a ratchet wheel milled out between two cylindrical stops with a lar- ger diameter than the diameter of the ratchet wheel, and that inside the tube frame of the bicycle a ratchet pawl is installed made to be able to be put in and out of engage ⁇ ment with the ratchet wheel by the means of a turnable, first lock mechanism.
  • a ratchet pawl is installed inside the tube frame of the bicycle a ratchet pawl is installed made to be able to be put in and out of engage ⁇ ment with the ratchet wheel by the means of a turnable, first lock mechanism.
  • the lock mechanism could be made to be operated by a key in such a way that the ratchet mechanism easily can be discon ⁇ nected by the owner, when he wants to use the bicycle.
  • the lock mechanism could be a gear-wheel engaged with a rack installed at the ratchet pawl, so that by turning of the lock mechanism the ratchet pawl can be put in or out of engagement with the ratchet wheel.
  • the burglary alarm also includes a second lock mechanism.
  • At least one of the lock mechanisms could be a cylinder lock and the other lock mechanism could be installed in such a way that it is only accessible through that tube part of the bicycle frame, inside which the lock mechanism is installed.
  • the first lock mechanism could in this way be made to be operated by a key, which is in the owner's possession only, while the other lock mechanism (system locking device) could be made to be operated by f.inst. an authorized bi ⁇ cycle dealer only.
  • FIG. 1 shows a crank with a milled out toothed wheel be- tween two cylindrical stops, which is a part of the burgla ⁇ ry alarm according with the invention.
  • Fig. 2 shows another part of the burglary alarm and
  • Fig. 3 shows a section of a part of the bicycle frame with the crank and the burglary alarm in accordance with the in- vention.
  • the part of the burglary alarm shown in fig. 2, consists of a cylindrical block 1 with milled out holes or passages for a cylinder lock 2, a cylinder lock 4, a toothed wheel 8 and in the block 1 a movable rack 7.
  • the rack 7 is attached to a sliding bolt 3 with a ratchet pawl 9.
  • the cylinder lock 4 is secured in the block 1 by the means of a pin 5.
  • the rack 7 and with that the sliding bolt 3 and the ratchet pawl 9 can be moved back and forth.
  • the ratchet pawl can be put in or out of engagement with the ratchet wheel 10 in the crank 12.
  • a stop 11 is screwed on, which prevents the removal of the crank 12 from the bi ⁇ cycle frame and thereby prevents the dismounting of the bur ⁇ glary alarm when it is in connection, i.e. the ratchet pawl 9 is engaged with the ratchet wheel 10.
  • the burglary alarm can only be dismounted by means of the cylinder lock 2, which can only be operated with an authori ⁇ zed key, and which is only accessible from the end of that tube part of the frame, inside which it is mounted, mainly the tube part of the frame for the bicycle saddle.
  • the invention also covers other mechanisms than the rack/ toothed wheel mechanisms 7, 8, which can put the ratchet pawl 9 in or out of engagement with the ratchet wheel 10.
  • the toothed wheel 8 could be replaced by an eccentric and the rack replaced with a bar with a stop for the eccentric.
